                             ____________ ___, 1996

Dear Fellow Shareholder:

        You are cordially invited to attend the Annual Meeting of Shareholders
of Vancouver Bancorp ("VB"), which will be held on Tuesday May 28, 1996, at
5:00 p.m., local time, at the Royal Oaks Country Club, 8917 N.E. Fourth Plain
Boulevard, Vancouver, Washington.

        At the Annual Meeting, you will be asked to consider and ratify a Plan
and Agreement of Reorganization and Merger, dated as of February 15, 1996 (the
"Merger Agreement"), between VB, West Coast Bancorp ("WCB") and HB Acquisition
Corporation ("HB"), WCB's wholly owned subsidiary, under the terms of which VB
will be merged with and into HB (the "Merger"), with the result that VB
shareholders would become shareholders of WCB.  The Merger is subject to
various conditions which are contained in the Merger Agreement.  The terms of
the Merger are described in the attached Proxy Statement, which also serves as
a Prospectus of WCB for its Common Stock to be issued in the Merger.  The
complete text of the Merger Agreement appears as Appendix A to the
Prospectus/Proxy Statement.  If the Merger is approved, each VB shareholder
will receive shares of WCB Common Stock for each share of VB Common Stock
owned, based on an exchange formula detailed in the Prospectus/Proxy Statement
which is intended to provide WCB shares with a market value of approximately
$66.95 for each share of VB exchanged in the merger.  The Board of Directors
has received an opinion from Columbia Financial Advisors, Inc. to the effect
that the consideration to be received by VB's shareholders in the Merger is
fair from a financial point of view.

        At the Annual Meeting, you will also be asked to elect seven directors
to VB's Board of Directors, each to serve a one- year term or until their
respective successors are elected and qualified, or until such time as the
Merger is effective.

        YOUR BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS IN THE BEST
INTERESTS OF VANCOUVER BANCORP AND ITS SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS
THAT YOU VOTE IN FAVOR OF THE MERGER.  YOUR BOARD OF DIRECTORS ALSO RECOMMENDS
THAT YOU VOTE FOR THE ELECTION OF THE SEVEN NOMINEES FOR DIRECTOR.  Approval of
the Merger requires the affirmative vote of the holders of a majority of the
outstanding shares of VB Common Stock.  Directors are elected by a plurality of
the votes cast for nominees.  We urge you to read the attached Prospectus/Proxy
Statement and to consider your vote carefully.  If you have any questions
regarding this material in advance of the Annual Meeting, please feel free to
call Anne M. Ryan, VB's Vice President and Secretary, at (360) 695-3439.
Regardless of the size of your holdings, it is important that your shares be
voted at the Annual Meeting.

        WHETHER OR NOT YOU PLAN TO ATTEND THE ANNUAL MEETING, PLEASE BE CERTAIN
TO COMPLETE, SIGN AND DATE THE ENCLOSED PROXY, AND RETURN IT PROMPTLY IN THE
POSTAGE-PAID ENVELOPE PROVIDED.  IF YOU ATTEND THE ANNUAL MEETING, YOU MAY VOTE
IN PERSON IF YOU WISH, EVEN THOUGH YOU HAVE PREVIOUSLY RETURNED YOUR PROXY.  IF
FOR ANY REASON YOU SHOULD DESIRE TO REVOKE YOUR PROXY, YOU MAY DO SO AT ANY
TIME BEFORE IT IS VOTED AT THE ANNUAL MEETING.

                               Very truly yours,


        James J. Pomajevich                           Lee S. Stenseth
        Chairman of the Board                         President

         PLEASE COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD

                            TO BE HELD MAY 28, 1996


TO THE SHAREHOLDERS OF VANCOUVER BANCORP:

        NOTICE IS HEREBY GIVEN that the Annual Meeting of Shareholders of
Vancouver Bancorp ("VB") will be held on Tuesday May 28, 1996, at 5:00 p.m.,
local time, at the Royal Oaks Country Club, 8917 N.E. Fourth Plain Boulevard,
Vancouver, Washington.  The Annual Meeting is for the following purposes:

        1.       MERGER AGREEMENT.  To consider and vote upon a proposal to
approve the Plan and Agreement of Reorganization and Merger, dated as of
February 15, 1996, as more fully described in the accompanying Prospectus/Proxy
Statement, and attached as Appendix A thereto.

        2.       ELECTION OF DIRECTORS.  To elect seven directors, each to hold
office for a one-year term, or until their respective successors are elected
and qualified, or until such time as the Merger is effective.

        3.       OTHER MATTERS.  To act upon such other matters as may properly
come before the Annual Meeting or any adjournment thereof.

        Only holders of record of the VB Common Stock, $1.00 par value per
share, at the close of business on April 18, 1996, the record date for the
Annual Meeting, are entitled to notice of and to vote at the Annual Meeting or
any adjournments or postponements thereof.  Shareholders desiring to do so may
dissent from the Merger and obtain payment for their shares in accordance with
the provisions of the Washington statute, RCW 23B.13, a copy of which is
included in the Prospectus/Proxy Statement.  See "THE MERGER -- Dissenters'
Rights of Appraisal" and Appendix C.

        All shareholders are cordially invited to attend the Annual Meeting
personally.  Whether or  not you are able to do so, it is important that you
complete, sign, date, and promptly return the accompanying proxy in the
enclosed postage-paid envelope in order to vote your shares of VB Common Stock.
Shareholders may revoke proxies previously submitted by completing a later-
dated proxy, by written revocation delivered to VB's secretary at or prior to
the Annual Meeting, or by appearing and voting at the Annual Meeting in person.
Attendance at the Annual Meeting will not of itself revoke a previously
submitted proxy.

                                       By Order of the Board of Directors,


                                       Anne M. Ryan, Secretary
Vancouver, Washington
__________ ___, 1996

YOUR VOTE IS IMPORTANT REGARDLESS OF THE NUMBER OF SHARES YOU OWN.  APPROVAL OF
THE MERGER REQUIRES THE AFFIRMATIVE VOTE OF HOLDERS OF A MAJORITY OF THE
OUTSTANDING SHARES OF VB COMMON STOCK.  IN ORDER TO ENSURE THAT THE REQUISITE
VOTES ARE OBTAINED, AND IN ORDER TO ENSURE A QUORUM, WE URGE YOU TO SIGN, DATE
AND RETURN THE ENCLOSED PROXY.

INTRODUCTION

        Pursuant to the Merger Agreement, WCB proposes to acquire VB by means
of a triangular merger, whereby VB would be merged with and into HB, WCB's
wholly-owned subsidiary, with the result that VB shareholders would become
shareholders of WCB, and the Bank of Vancouver (the "Bank") would become a
wholly-owned subsidiary bank of WCB.

        The respective Boards of Directors ("Boards") of WCB, HB and VB have
unanimously adopted the Merger Agreement.  The VB Board has unanimously
recommended that the shareholders of VB vote to approve the Merger Agreement.
Subject to approval by VB's shareholders, receipt of required regulatory
approvals, and satisfaction of certain other conditions, VB will be merged with
and into HB.  VB's shareholders will receive shares of WCB Common Stock in
exchange for their shares of VB Common Stock.  See "THE MERGER -- Basic Terms
of the Merger."

VB SHAREHOLDER MEETING

        An Annual Meeting ("Meeting") of VB's shareholders will be held on
Tuesday May 28, 1996, at 5:00 p.m., local time, at the Royal Oaks Country Club,
8917 N.E. Fourth Plain Boulevard, Vancouver, Washington.  The purposes of the
Meeting are (i) to vote to approve the Merger Agreement providing for the
merger of VB with and into HB, and (ii) to elect seven nominees to the VB
Board, each of whom will serve a one-year term, or until his or her successor
has been elected and qualified or the Merger is consummated.

        Only shares of VB Common Stock held of record as of April 18, 1996 (the
"Record Date") are entitled to notice of, and to vote at, the Meeting.  On the
Record Date, there were 141,461 shares of VB Common Stock outstanding.  The

<PAGE>   13
between former West Coast Bancorp ("Old WCB") and Commercial, Old WCB and
Commercial were merged on February 28, 1995, with WCB as the surviving
corporation.  Old WCB was a one-bank holding company headquartered in Newport,
Oregon.  The combined company commenced operations on March 1, 1995 and, with
approximately $517 million in total assets at December 31, 1995, is the second
largest bank holding company based in Oregon.

        WCB is headquartered in Lake Oswego, Oregon, and its principal business
activities are conducted through its three bank subsidiaries, The Commercial
Bank -- Valley Commercial Bank, and The Bank of Newport -- each of which is an
Oregon state- chartered, full-service commercial bank with deposits insured by
the Federal Deposit Insurance Corporation ("FDIC").  At February 29, 1996,
WCB's subsidiary banks had facilities in a total of 21 cities and towns in
Oregon, operating a total of 26 full-service branches and two limited service
branches.

        In October 1994, WCB and The Commercial Bank entered into a merger
agreement with Great Western Bank of Dallas, Oregon.  Under the terms of the
merger agreement, Great Western Bank was merged into The Commercial Bank on
March 31, 1995, and the shareholders of Great Western Bank received shares of
WCB Common Stock in exchange for their shares.  At March 31, 1995, Great
Western Bank had total assets of approximately $8.1 million and shareholders'
equity of approximately $873,000.

        WCB's executive offices are located at 5335 S.W. Meadows Road, Suite
201, Lake Oswego, Oregon  97035, and its telephone number is (503) 684-0884.
Additional information concerning WCB and its business is included in the

"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

        HB.  HB is a Washington bank holding company that was incorporated in
1996 to facilitate WCB's acquisition of VB.  HB is WCB's wholly owned
subsidiary.  Immediately after Closing of the Merger, WCB intends to merge HB
with and into WCB.  HB's address and telephone number are the same as WCB's.

        VB.  VB is a Washington corporation that was incorporated in 1994 for
the purpose of being a holding company for the Bank, under an agreement and
plan of exchange pursuant to which shareholders of the Bank became shareholders
of VB.  VB is registered with the Board of Governors of the Federal Reserve
System as a bank holding company under the Bank Holding Company Act of 1956, as
amended ("BHCA"), and has no significant operations separate from the Bank.

        The Bank is a state-chartered bank organized under Washington law in
June, 1989.  The Bank, which has a sole office in Vancouver, Washington, is a
local community bank with a commitment to service to the businesses and
residents of Clark County, Washington.  The Bank offers commercial banking
services (including commercial loans, accounts receivable and inventory
financing, consumer installment loans, acceptance of deposits, and personal
savings and checking accounts), primarily to small- and medium-size businesses,
professionals and retail customers.  Its deposits are insured by the FDIC.  As
of December 31, 1995, the Bank had deposits of approximately $70.7 million and
assets of approximately $78.9 million.

        VB's principal offices are located at the main office of the Bank, at

THE MERGER; EXCHANGE RATIO

        In accordance with the Merger Agreement, on the Effective Date, VB will
be merged with and into HB, with HB as the surviving corporation.  Upon
consummation of the Merger, each holder of shares of VB Common Stock, other
than dissenting shares, will be entitled to receive, in exchange for each share
of VB Common Stock held of record by such shareholder as of the Effective Date,
the number of shares of WCB Common Stock obtained by dividing $11,581,000 by
the Average Closing Price or the Modified Average Closing Price, whichever
applies, and by further dividing such quotient by the aggregate number of
shares of VB Common Stock that are issued and outstanding, including shares
subject to unexercised options, as of the Effective Date.  The formula is
designed to result in VB shareholders receiving WCB Common Stock having a
market value at the time of Closing of approximately $66.95 in exchange for
each share of VB Common Stock held, so long as the WCB Common Stock is trading
at a price between $15.30 and $18.70 per share.  Cash will be paid in lieu of
issuing fractional shares of WCB Common Stock.  Upon completion of the Merger,
shareholders of VB will no longer own any stock in VB.

        For more detailed information concerning the Merger, and how VB
Shareholders may exchange certificates representing shares of VB Common Stock,
see "THE MERGER -- Basic Terms of the Merger; Cash for Fractional Shares;
Exchange of Stock Certificates."

EFFECTIVE DATE

        The parties presently expect to consummate the Merger during the second
quarter of 1996, although the timing is subject to the satisfaction of certain
conditions.  The date on which the Merger is consummated, even if this date is
the Postponed Effective Date under the Merger Agreement, is referred to in this
Prospectus/Proxy Statement as the "Effective Date."  The Merger Agreement
provides that if the Merger has not been consummated by October 31, 1996, at
any time after such date, the Board of either WCB or VB may vote to abandon the
Merger.  See "THE MERGER -- Basic Terms of the Merger."

REASONS FOR THE MERGER; RECOMMENDATION OF THE VB BOARD

        The VB Board has unanimously determined that the Merger is fair to and
in the best interests of VB's shareholders.  In making this determination, the
VB Board considered a variety of factors, including the value of the WCB Common
Stock that the shareholders of VB will receive in exchange for their shares of
VB Common Stock, the continued ability of the Bank to continue to provide
competitive and comprehensive services in the markets in which it operates, and
the parties' shared belief in community banking, which emphasizes
responsiveness to local markets and the delivery of personalized services to
customers.  The VB Board believes that the Merger will allow the Bank to
continue to provide the advantages of personal community banking to VB's
current customers, and will also allow VB to realize a premium, thus enhancing
shareholder value.  THE VB BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AS ADVISABLE AND IN THE BEST INTERESTS OF VB AND ITS SHAREHOLDERS AND
RECOMMENDS THAT VB'S SHAREHOLDERS APPROVE THE MERGER AGREEMENT.  See
"BACKGROUND OF AND REASONS FOR THE MERGER."

OPINION OF FINANCIAL ADVISOR

        Columbia Financial Advisors, Inc. ("CFA"), VB's financial advisor, has
delivered a written opinion to the VB Board dated the date of this
Prospectus/Proxy Statement, to the effect that the Merger is fair, from a
financial perspective, to VB and its shareholders.  A copy of CFA's opinion
setting forth the limits of its review, assumptions made, matters considered
and procedures followed, is attached to this Prospectus/Proxy Statement as
Appendix D and should be read in its entirety by VB's shareholders.  See
"BACKGROUND OF AND REASONS FOR THE MERGER -- Opinion of VB Financial Advisor."

BOARD OF DIRECTORS AND EXECUTIVE OFFICERS OF WCB AND THE BANK

        Upon consummation of the Merger, the WCB Board will consist of 12
current directors of WCB, in addition to James J.  Pomajevich, who is presently
the Chairman of the VB Board.  WCB has agreed to appoint Mr. Pomajevich to the
WCB Board upon consummation of the Merger, effective as of the Effective Date.
WCB will also permit Lee S. Stenseth, the Bank's President, to attend meetings
of the WCB Board as an ex-officio member until the end of his service as
President of the Bank.  The respective executive officers of WCB and the Bank
in office immediately before the Effective Date are expected to remain
unchanged following consummation of the Merger.  On the Effective Date, the
Bank's Board will consist of all persons who were directors of the Bank
immediately before the Merger, plus an additional WCB director to be designated
by WCB to the Bank's Board.  See "THE MERGER -- Directors and Officers;
Interests of Certain Persons in the Merger."

TRADING MARKET

        The WCB Common Stock is quoted on the Nasdaq Stock Market under the
symbol "WCBO," and is registered as a class with the SEC under the Exchange
Act.  Accordingly, WCB is required to file certain periodic and annual reports
with the SEC and make information about WCB available to its shareholders and
the public.  VB is not subject to the information and reporting requirements of
the Exchange Act and its Common Stock is not actively traded or listed on any
market system.

CONDITIONS; REGULATORY APPROVALS

        Consummation of the Merger is conditioned on (a) approval of the Merger
Agreement by the holders of not less than a majority of the outstanding shares
of VB Common Stock; (b) receipt of all necessary approvals of the Merger by
governmental regulatory agencies, including the FRB and the Director of the
Washington State Department of Financial Institutions ("Washington Director");
(c) receipt by each party of a favorable tax opinion from Graham & Dunn, P.C.;
(d) receipt of a letter from Arthur Andersen LLP to the effect that the Merger
qualifies for pooling of interests accounting treatment; (e) the continuing
accuracy of the representations and warranties of each party; (f) the
performance of specified obligations by each party; and (g) certain other
conditions.  WCB has filed with the FRB and the Washington Director the
appropriate applications for approval of the Merger, each of which has been
accepted for processing.  See "THE MERGER -- Conditions to the Merger" and
"SUPERVISION AND REGULATION."

TERMINATION AND AMENDMENT OF THE MERGER AGREEMENT

        The Merger Agreement may be terminated, and the Merger abandoned,
before the Effective Date, whether before or after its adoption by the
shareholders of VB by (i) the respective majority votes of the



                                     - 4 -
<PAGE>   16
WCB and VB Boards, or (ii) either the WCB or the VB Board under certain
specified circumstances, including a failure to consummate the Merger by
October 31, 1996.  The Merger Agreement may be amended at any time before the
Effective Date if both the WCB and VB Boards approve, but no amendment reducing
the amount or changing the form of any consideration which is to be received by
VB shareholders can be effected without the approval of VB shareholders.  See
"THE MERGER --  Amendment and Termination of Merger Agreement."

TAX TREATMENT OF THE MERGER

        Consummation of the Merger is conditioned upon receipt by WCB, and
delivery to VB, of an opinion from Graham & Dunn, P.C. to the effect that (i)
the Merger will constitute a tax-free reorganization within the meaning of
Section 368(a)(1)(A) of the Internal Revenue Code of 1986, (the "Code") as
amended, (ii) pursuant to the provisions of Section 354(a)(i) of the Code, no
gain or loss will be recognized with respect to each shareholder of VB who
exchanges his or her shares of VB Common Stock solely for shares of WCB Common
Stock, and (iii) the payment of cash to a shareholder of VB in lieu of a
fractional share of WCB Common Stock will be treated as a distribution in
redemption of the fractional share interest, subject to the limitations of
Section 302 of the Code.  See "THE MERGER -- Certain Federal Income Tax
Matters."

ACCOUNTING TREATMENT OF THE MERGER

        It is anticipated that the Merger will be accounted for as a pooling of
interests by WCB under generally accepted accounting principles.  The Merger
Agreement provides that, as a condition to WCB's obligation to consummate the
Merger, WCB must receive a letter from Arthur Andersen LLP, WCB's independent
auditors, to the effect that the Merger will qualify for pooling of interests
accounting treatment.  See "THE MERGER -- Accounting Treatment of Merger."

DISSENTERS' RIGHTS OF APPRAISAL

        Holders of VB Common Stock have the right to dissent from the Merger
and, if they follow certain procedures and the Merger is effectuated, to obtain
payment of the fair value of their shares in cash, in accordance with
applicable provisions of Washington state law.  A SHAREHOLDER'S FAILURE TO
FOLLOW EXACTLY THE PROCEDURES SPECIFIED IN THE WASHINGTON STATUTE WILL RESULT
IN LOSS OF SUCH SHAREHOLDER'S DISSENTERS' RIGHTS.  Accordingly, the
shareholders of VB wishing to dissent from the Merger are urged to read
carefully "THE MERGER -- Dissenters' Rights of Appraisal," and the copy of
Chapter 13 of the Washington Business Corporation Act set forth in Appendix C
to this Prospectus/Proxy Statement.

<PAGE>   17
INTERESTS OF CERTAIN PERSONS IN THE MERGER

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

        As a condition to the execution of the Merger Agreement, the Bank has
entered into an employment agreement with Mr.  Stenseth, under the terms of
which he will continue as President of the Bank after the Merger.  Further, WCB
will permit Mr.  Stenseth to attend meetings of the WCB Board as an ex-officio
member until the end of his service as President of the Bank.  WCB has also
agreed to appoint Mr. Pomajevich, currently the Chairman of the VB Board, to
the WCB Board effective upon Closing.  The directors and management of the Bank
are expected to retain in their respective positions with the Bank after the
Merger.  For additional information regarding these matters, see "THE MERGER --
Interests of Certain Persons in the Merger."

COMPARISON OF SHAREHOLDERS' RIGHTS

        Shareholders of VB who receive shares of WCB Common Stock in exchange
for their shares of VB Common Stock will be governed, with respect to their
rights as shareholders, by WCB's Articles of Incorporation and Bylaws, and by
Oregon law.  Prior to the Merger, the rights of VB's shareholders are
determined under VB's Articles of Incorporation and Bylaws, and under
Washington law.  For a discussion of certain material differences in the rights
of shareholders of WCB and VB and an explanation of certain possible
antitakeover effects of certain provisions in WCB's Articles of Incorporation
and Bylaws, see "COMPARISON OF SHAREHOLDERS' RIGHTS."

STOCK OPTION AGREEMENT

        As an inducement to WCB to enter into the Merger Agreement, VB has
granted an Option to WCB, by agreement dated as of February 15, 1996, to
purchase up to approximately 19.9% of the then-outstanding VB Common Stock at a
price equal to $64.00 per share.  WCB may exercise the Option only upon (i) the
occurrence of certain events (none of which have occurred), and (ii) obtaining
any regulatory approvals necessary for the acquisition of the VB Common Stock
subject to the Option.  At the request of WCB, under limited circumstances, VB
will repurchase for a formula price the Option and any shares of VB Common
Stock purchased upon exercise of the Option and beneficially owned by WCB at
that time.  See "THE MERGER - Stock Option Agreement."

                        EQUIVALENT PER COMMON SHARE DATA
                                  (UNAUDITED)

        The following table presents selected per common share data for (i)
WCB, (ii) WCB and VB pro forma combined, (iii) VB and (iv) equivalent pro forma
data per share of VB after giving effect to the Merger on a pooling of
interests basis.  The pro forma condensed combined financial data are not
necessarily indicative of actual or future operating results or the financial
position that would have occurred or will occur upon the consummation of the
Merger.  The pro forma equivalent data are based on the respective pro forma
combined amounts per shared multiplied by three different exchange ratios,
assuming the Average Closing Price for WCB Common Stock was: (i) $17.00 per
share, (ii) $15.30 per share, and (iii) $18.70 per share.  On April 18, 1996,
the last trading day prior to the date of this Proxy Statement/Prospectus, the
closing price of WCB Common Stock was $18.25 per share; if that price were the
Average Closing Price under the Merger Agreement, the exchange ratio would be
3.6684 WCB shares for each share of VB outstanding.  This data should be read
in conjunction with the financial statements and other financial and pro forma
financial information with respect to WCB and VB included elsewhere in this
Prospectus/Proxy Statement or incorporated herein by reference.

                       ANNUAL MEETING OF VB SHAREHOLDERS

DATE, TIME, AND PLACE

        The Meeting will be held on Tuesday May 28, 1996, at 5:00 p.m., local
time, at the Royal Oaks Country Club, 8917 N.E.  Fourth Plain Boulevard,
Vancouver, Washington.

PURPOSE OF THE MEETING

        The purpose of the Meeting are as follows:  (i) to consider and vote
upon approval of the Merger Agreement; (ii) to elect seven directors to serve a
one-year term each, or until their respective successors have been elected and
qualified, or until the Merger is consummated; and (iii) to act upon such
matters, if any, as may properly come before the Meeting.

SHARES OUTSTANDING AND ENTITLED TO VOTE; RECORD DATE

        The VB Board has fixed the close of business on April 18, 1996 as the
Record Date for determining the holders of shares of VB Common Stock entitled
to notice of and to vote at the Meeting.  At the close of business on the
Record Date, there were 141,461 shares of VB Common Stock issued and
outstanding held by approximately 200 holders of record.  See "INFORMATION
CONCERNING VB -- Security Ownership of Certain Beneficial Owners and
Management."  Holders of record of VB Common Stock on the Record Date are
entitled to one vote per share, and are also entitled to exercise dissenters'
rights if certain procedures are followed.  See "Dissenters' Rights of
Appraisal" and Appendix C.

VOTE REQUIRED

        The affirmative vote of a majority of all shares of VB Common Stock
outstanding on the Record Date is required to approve the Merger Agreement.  A
plurality of the votes cast at the Meeting by holders of shares of VB Common
Stock is required for the election of persons nominated to serve as directors.
As to both the Merger and the election of each director nominee to the VB
Board, VB's shareholders are entitled to one vote for each share of VB Common
Stock held.  The presence of a majority of the outstanding shares of VB Common
Stock in person or by proxy is necessary to constitute a quorum of shareholders
for the Meeting.  For this purpose, abstentions and broker nonvotes (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 broker or nominees do not have
discretionary power to vote) are counted in determining the shares present at a
meeting.  For voting purposes, however, only shares affirmatively voted for the
approval of the Merger Agreement, and neither abstentions nor broker nonvotes,
will be counted as favorable votes in determining whether the Merger Agreement
is approved by the holders of VB Common Stock.  As a consequence, abstentions
and broker nonvotes will have the same effect as votes against approval of the
Merger Agreement.

        As of the Record Date, VB's directors and executive officers and their
affiliates owned and were entitled to vote 50,855 shares at the Meeting,
representing approximately 35.9 percent of the outstanding shares of VB Common
Stock.  Each VB director has agreed to vote all shares of VB Common Stock held
or controlled by him or her (a total of 50,289 shares) in favor of approval of
the Merger.

VOTING, SOLICITATION, AND REVOCATION OF PROXIES

        If the enclosed proxy is duly executed and received in time for the
Meeting, it will be voted in accordance with the instructions given.  If no
instruction is given, it is the intention of the persons named in the proxy to
vote the shares represented by the proxy FOR THE ELECTION OF THE BOARD'S



                                     - 14 -
<PAGE>   26
NOMINEES FOR DIRECTOR, FOR THE APPROVAL OF THE MERGER AGREEMENT AND IN THE
PROXY'S DISCRETION ON ANY OTHER MATTER COMING BEFORE THE MEETING, unless
otherwise directed by the proxy.  Any proxy given by a shareholder may be
revoked before its exercise by written notice to the Secretary of VB, or by a
subsequently dated proxy, or in open meeting before the shareholder vote is
taken.  The shares represented by properly executed, unrevoked proxies will be
voted in accordance with the instructions in the proxy.  With respect to both
the approval of the Merger and the election of each director nominee to the
open positions on the VB Board, shareholders are entitled to one vote for each
share of VB Common Stock held on the Record Date.

        The proxy for the Meeting is being solicited on behalf of the VB Board.
VB will bear the cost of solicitation of proxies from its shareholders.  In
addition to using the mails, proxies may be solicited by personal interview,
telephone, and wire.  Banks, brokerage houses, other institutions, nominees,
and fiduciaries will be requested to forward their proxy soliciting material to
their principals and obtain authorization for the execution of proxies.
Officers and other employees of VB may solicit proxies personally.  VB is not
expected to pay any compensation for the solicitation of proxies, but will,
upon request, pay the standard charges and expenses of banks, brokerage houses,
other institutions, nominees, and fiduciaries for forwarding proxy materials to
and obtaining proxies from their principals.

                    BACKGROUND OF AND REASONS FOR THE MERGER

BACKGROUND OF THE MERGER

        Since its formation in 1989, VB has enjoyed progressive earnings gains
and strong asset growth in its Vancouver, Washington market.  Although VB's
founding directors anticipated that they might consider a sale of the company
after the Bank was well-established and profitable, the VB Board and management
have not seriously pursued a possible sale or merger given their record of
performance.  In early 1995, VB received an unsolicited inquiry from another
community banking organization concerning a possible merger of their companies.
This inquiry gave the VB Board and management an opportunity to reassess their
organization, their success to date, the circumstances under which they might
be interested and/or required to consider a merger possibility.  Discussions
with the community banking organization broke off in July of 1995.

        In September 1995, Rodney B. Tibbatts, WCB's Co-President and Co-Chief
Executive Officer, contacted Mr. Stenseth, President of both VB and the Bank,
to arrange a luncheon meeting.  The purpose of the meeting was to gain insight
into VB and the Bank's strategic plans for the future, along with informing Mr.
Stenseth of WCB's mission and strategic intent.  Mr.  Tibbatts indicated that
WCB desired to have a presence in southwest Washington and that VB could
represent a viable partner to enable this goal to be achieved.  Mr. Stenseth
indicated the conversation was timely in that VB was holding a directors
retreat in the near future to discuss strategies for 1996 and beyond.
Following the VB Board retreat, it was concluded that the timing could be
opportune to pursue discussions with WCB.  Accordingly, in October 1995,
Messrs. Stenseth and Pomajevich, the Chairman of the VB Board, met with Mr.
Tibbatts and Victor L. Bartruff, WCB's other Co-President and Co-Chief
Executive Officer, along with Lester Green and Gary Putnam, the Chairman and
Vice Chairman, respectively, of the WCB Board, to share the philosophies of the
two organizations in order to determine if further discussions would be
productive.  The parties reported on their respective conversations at their
next Board meetings and, feeling that a combination of the two institutions
would be consistent with the objectives of both parties, on October 17, 1995,
WCB and VB signed a Confidentiality Agreement.  Subsequently, in late October,
a joint dinner meeting was held involving  the seven members of the VB Board,
the six- member Executive Committee of the WCB Board, and WCB's Chief Financial
Officer, Donald A. Kalkofen.

        Subsequently, certain directors and management teams of both parties
held a series of meetings to further explore the possible combination of WCB
and VB.  WCB and VB then conducted detailed due diligence



                                     - 15 -
<PAGE>   27
reviews of each other's assets, business and financial conditions, consulting
on the proposed transaction with their respective independent public
accountants, legal counsel, and Board members.  Also, the WCB negotiating team
of Messrs. Tibbatts, Bartruff, Green, Putnam and Kalkofen met on several
occasions with Messrs. Stenseth and Pomajevich, and on occasion other VB
directors.  After reaching a consensus on a number of basic issues involving a
combination of the companies, including a stock exchange ratio, VB retained a
financial advisor.  On December 12, 1995, the WCB Board met and on December 21,
1995 the VB Board met, and both approved proceeding with formal negotiations
towards a definitive Merger Agreement.

        At special meetings of the VB and WCB Boards held on February 15, 1996,
the proposed combination was considered in detail.  The WCB Board, along with
its counsel, Graham & Dunn, P.C., reviewed the Merger Agreement together with
its exhibits.  After considering 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, the WCB Board unanimously
approved the transaction.  The VB Board, with advice from its legal counsel,
Foster Pepper & Shefelman, reviewed the Merger Agreement and considered the
potential benefit of the proposed Merger to VB and its shareholders, taking
into account the financial and valuation analysis of the Merger, the terms of
the Merger Agreement and a report regarding the fairness of the transaction,
from a financial point of view, presented by VB's financial advisor, CFA.  At
this meeting, the VB Board unanimously determined that the proposed Merger was
fair to and in the best interest of VB and its shareholders, and therefore
recommended that the Merger Agreement be submitted to VB's shareholders for
approval.  At each meeting, the Merger, Exchange Ratio, and related
transactions were unanimously approved by all members of the respective Boards
present, subject to the approval of VB shareholders, obtaining necessary
regulatory approvals, and the further conditions set forth in the Merger
Agreement.

REASONS FOR THE MERGER - GENERAL

        VB and WCB share a community banking philosophy and strategy, which
emphasizes responsiveness to local markets and delivery of personalized service
through locally managed banks.  The parties believe that a bank holding company
composed of autonomous banks, emphasizing high quality personalized customer
service and strong local identification is a viable alternative to the
super-regional organizations which have acquired many smaller independent banks
in recent years and operated them as branches.  WCB expects to continue to
emphasize this strategy after the Merger and intends to operate  the  Bank of
Vancouver along with its present subsidiaries -- The Bank of Newport, The
Commercial Bank and Valley Commercial Bank -- as separate subsidiaries with
local management and directors that are involved in, and knowledgeable about,
the respective communities of WCB's subsidiary banks.

        The parties believe that the Merger will enable the Bank to provide
enhanced services to customers and to compete more effectively in the present
banking environment, which is dominated by much larger institutions.  The
parties' geographic markets and products are complementary.  The Bank is
located in Vancouver, Washington, with its primary market area Clark County,
Washington.  This market is immediately adjacent to the greater Portland,
Oregon, market in which several offices of WCB's three present subsidiary banks
are located.  The city of Vancouver, Washington, and Clark County are
considered a part of the Portland metropolitan area.  VB's primary focus is on
the small- to medium-sized businesses within its market area which is
consistent with the niche banking philosophy of the three business banking
offices of The Bank of Newport located in the Portland, Oregon area.

        While VB's loan portfolio focuses on business lending, with a
concentration in real estate developments, the institutions' portfolios
complement each other both geographically and by industry types.  WCB's loan
portfolio has a broad diversity with some concentration in the agricultural,
manufacturing, fishing, tourism, and real estate industries.  WCB offers a
range of non-traditional products, such as annuities, mutual funds and
brokerage services, which are not presently offered by VB.  In addition WCB,
through its Trust Division -- West Coast Trust -- offers trust and employee
benefit plans which are not presently offered by VB.  It is



                                     - 16 -

expected that the parties' complementary market areas, product mixes and areas
of expertise will provide additional opportunity for growth, revenue
enhancement, and increased quality of customer services.

        To a lesser extent, the Merger is expected to provide benefits to the
parties through increased efficiencies and other savings, particularly in the
areas of data processing, loan participation, and through enhanced marketing
efforts.  Moreover, having banking offices on both sides of the Columbia River
is expected to enable the parties to more effectively pursue their strategy of
providing community-style banking services to small and medium-sized businesses
throughout the entire metropolitan area, including those in Oregon and Clark
County, Washington.

REASONS FOR THE MERGER - WCB

        At its meeting on February 15, 1996, the WCB Board determined that the
Merger and Merger Agreement are fair to and in the best interests of WCB and
its shareholders.  In considering the Merger, the WCB Board determined that the
Merger would be consistent with WCB's strategic intent in expanding its
community banking organization.  With VB, WCB can potentially provide customers
and shareholders with certain advantages of a community banking organization as
well as the larger banking organization.

        WCB determined that the Merger would advance WCB's strategic plan
because of its belief that the Merger will combine two financially-sound
institutions with complementary businesses and strategies, thereby creating a
stronger combined organization with greater size, flexibility, efficiency, and
profitability.  The WCB Board believes that (i) each institution is currently
well-managed, (ii) the companies have compatible management philosophies and
strategic focuses, (iii) each institution will contribute complementary
business strengths resulting in a well meshed diversified institution, and (iv)
the strong capitalization of the combined organization will allow it to take
advantage of future acquisition opportunities.  The WCB Board also believes
that the Merger will allow the combined organization to compete effectively in
the rapidly changing marketplace of banking and financial services and to take
advantage of opportunities for growth and diversification in both Oregon and
Washington.

        In reaching its determination, the WCB Board consulted with WCB's
management as well as WCB's accounting and legal advisors and considered a
number of factors, including the following:

        -        The effectiveness of the Merger in implementing WCB's basic
                 strategy, and in responding to changes in the banking industry
                 which have made competing as a community banking organization
                 more difficult;

        -        The WCB Board review based in part on a presentation by WCB
                 management regarding (i) its due diligence review of VB,
                 including the business, operations, earnings, asset quality,
                 financial condition and corporate culture of VB on a
                 historical, prospective and pro forma basis, (ii) product mix,
                 the compatibility of corporate roles and the respective
                 contributions the parties would bring to a combined
                 organization, and (iii) the expanded opportunities for revenue
                 enhancement and synergies that are expected to result from the
                 Merger;

        -        The terms of the Merger Agreement, the VB Stock Option
                 Agreement and the other documents executed in conjunction with
                 the Merger;

        -        WCB's long-term strategy of seeking to expand its operations
                 along the I-5 corridor and particularly its stated goal of
                 expanding its banking operations throughout the
                 Portland-Metropolitan area, including southwest Washington;
                 and





                                     - 17 -
<PAGE>   29
        -        The current and prospective economic environment facing
                 financial institutions generally and WCB in particular.

The WCB Board did not assign any specific or relative weight to the foregoing
factors in the course of its consideration.

REASONS FOR THE MERGER - VB

        The VB Board believes that the terms of the Merger, which are the
product of arms length negotiations between representatives of VB and WCB, are
fair and in the best interests of VB and its shareholders.  In the course of
reaching its determination, the VB Board consulted with legal counsel with
respect to the legal duties of the VB 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.

        At its meeting on February 15, 1996, the VB Board unanimously
determined that the Merger and Merger Agreement are fair to, and in the best
interests of VB and its shareholders and recommended the Merger Agreement be
submitted to the shareholders of VB for approval.  In addition to the overall
objectives of enhancing shareholder value and providing high-quality community
banking services in Vancouver and surrounding communities, the VB Board
considered the fairness opinion of CFA, and a number of additional factors,
including the following:

        -        VB shareholder value would be significantly enhanced by the
                 value of WCB Common Stock being issued in the Merger;

        -        WCB stock is relatively actively traded, thus creating a far
                 more marketable and liquid security for VB shareholders;

        -        The Merger is structured as a tax-free exchange of stock,
                 permitting VB shareholders the opportunity to continue to
                 invest in a community banking organization;

        -        WCB's financial condition, businesses and prospects and the
                 economic prospects of the markets served by both parties
                 appear to be attractive;

        -        The Merger would allow VB to provide trust, investment and
                 mortgage services to VB customers;

        -        The combined organization would enable the Bank to offer
                 larger loans to customers due to higher legal lending limits;

        -        The combined organization is expected to provide increased
                 opportunities to employees;

        -        The structure of the Merger would allow the Bank to retain its
                 name and local identity, Board and management team, enabling
                 it to continue to provide responsive, quality, community
                 banking services to its customers; and

        -        The Merger is expected to receive regulatory approval and is
                 not conditioned upon the approval of any shareholder group
                 other than VB.

The VB Board did not ascribe relative or specific weights to any factor in its
evaluation of the Merger.

OPINION OF VB FINANCIAL ADVISOR

        VB retained CFA as its exclusive financial advisor pursuant to an
engagement letter dated February 5, 1996 (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 VB, having
acted as its financial advisor in connection with initiating and participating
in the negotiations with WCB leading to the Merger Agreement.  The VB Board
selected CFA to act as VB's exclusive financial advisor based on CFA's
experience in mergers and acquisitions and in securities valuation generally.

        On February 15, 1996, CFA issued its opinion to the VB 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 VB and its
shareholders.  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 VB shareholder as to how such shareholder
should vote at the Meeting.  No limitations were imposed  by the VB Board on
CFA in respect to the investigations made or procedures followed by CFA in
rendering its opinions.

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

        CFA analyzed the total Purchase Price 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 cost and varying account 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 VB's assets and liabilities, customer relations, market
presence, image and reputation, staff expertise and depth, little weight is
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



                                     - 19 -
<PAGE>   31
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 weight 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 institutions 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 VB,
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 $100 million that sold for 100% common stock from
January, 1988 to January, 1996.

        Comparable Sales Multiples.  CFA calculated a "merger consideration
multiple" of VB's Adjusted Book Value (using the estimated June 30, 1996,
stockholders' equity) based on the ratio of price to adjusted stockholders'
equity for a sample of Northwest banking institutions with assets below $100
million which sold between January, 1988 and January, 1996, and a sample of
banking institutions located in western Washington and western Oregon with
total assets below $100 million which sold between March, 1990 and January
1996.  Based on these two samples, the merger consideration multiple values
suggested for VB shares based on the estimated June 30, 1996 stockholders'
equity were $60.42 and $74.52, respectively.

        Transaction Value as a Percentage of Total Assets.  CFA calculated the
percentage of total assets which the transaction represents as a price level
indicator.  The transaction value as a percentage of total assets facilitates a
truer price level comparison with comparable banking organizations, regardless
of the differing levels of stockholders equity and earnings.  In this instance,
a transaction value of $66.95 per share results in a transaction value as a
percentage of total assets of 13.52%.  The median price as a percentage of
total assets for a sample of Northwest banking institutions with assets below
$100 million which sold between January, 1988 through January, 1996, and a
sample of Northwest banking institutions with total assets below $100 million
which sold between 1990 and 1995, was 13% and 15%, respectively.

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

        Net Present Value Analysis.  The investment or earnings value of any
banking organization's stock is an estimate of the present value of future
benefits, usually earnings, dividends, or cash flow, which will accrue to the
stock.  An earnings value is calculated using an annual future earning stream
over a period of time of not less than five years, and the residual or terminal
value of the earnings stream after five years, using VB's estimates of future
growth and an appropriate capitalization or discount rate.  CFA's calculations
were based on an analysis of the banking industry, VB's earnings estimates for
1996-2000, historical levels of growth and earnings, and the competitive
situation in VB's market area.  Using discount rates of 16% and 18%, acceptable
discount rates considering the risk-return relationship most investors would
demand of an investment of this type, as of the valuation date, the "Net
Present Value of Future Earnings:  provided a range of $63.13 to $67.76 per
share.

        When the net asset value, market value and investment value approaches
are subjectively weighed, using the appraiser's experience and judgment, 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, VB has agreed to pay
CFA a fee of $15,000.  In addition, VB has agreed to reimburse CFA for its
reasonable out-of-pocket expenses, including the fees and disbursements of its
counsel, and to indemnify CFA against certain liabilities.

PROSPECTUS/PROXY STATEMENT, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS
CONSIDERED, AND LIMITS ON THE REVIEW UNDERTAKEN BY CFA IS ATTACHED TO THIS
PROSPECTUS/PROXY STATEMENT AS APPENDIX D.  THE SHAREHOLDERS OF VB ARE ADVISED
TO READ THIS DOCUMENT IN ITS ENTIRETY.  CFA'S OPINIONS ARE DIRECTED ONLY TO THE
EXCHANGE RATIO IN THE MERGER AND DO NOT CONSTITUTE RECOMMENDATIONS TO ANY VB
SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE VB MEETING.  FURTHER,
THE SUMMARY OF THE OPINION OF CFA SET FORTH IN HEREIN IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION CONTAINED IN APPENDIX D.
THE CFA OPINION DELIVERED TO THE VB BOARD AND DATED FEBRUARY 15, 1996, IS
SUBSTANTIALLY IDENTICAL TO THE OPINION ATTACHED HERETO.

RECOMMENDATION OF THE VB BOARD

        THE VB BOARD UNANIMOUSLY RECOMMENDS THAT THE VB SHAREHOLDERS VOTE FOR
THE APPROVAL OF THE MERGER AGREEMENT.

                                   THE MERGER

GENERAL

        The following description of certain aspects of the Merger does not
purport to be complete and is qualified in its entirety by reference to the
Merger Agreement.  All VB shareholders are urged to read the Merger Agreement
carefully.  VB shareholders are being asked to approve the Merger in accordance
with the terms of the Merger Agreement.

BASIC TERMS OF THE MERGER

        The Merger Agreement provides for the merger of VB with and into HB,
WCB's wholly-owned subsidiary, with the result that VB shareholders would
become shareholders of WCB and the Bank would become a wholly-owned subsidiary
of WCB.  VB would cease to exist after the Merger.  While WCB and VB 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 the Merger."

        Under the terms of the Merger Agreement, WCB would acquire VB for an
aggregate purchase price of $11,581,000, or $66.95 per share of VB Common
Stock.  WCB would acquire VB by means of a triangular merger through which VB
would be merged with and into HB, WCB's wholly-owned subsidiary organized
solely to effect this transaction.  As a result, VB shareholders, other than
those who duly exercise dissenters' rights, would become shareholders of WCB
(See "THE MERGER -- Dissenters' Rights of Appraisal").  Upon consummation of
the Merger, each holder of shares of VB Common Stock, other than dissenting
shares, will be entitled to receive shares of WCB Common Stock in exchange for
the shares of VB Common Stock held of record by such shareholder as of the
Effective Date.  The number of shares of WCB Common Stock to be received for
each share of VB Common Stock is the number obtained by dividing $11,581,000 by
either the Average Closing Price or the Modified Average Closing Price (as
defined in the Merger Agreement and discussed in more detail below), whichever
applies, and by further dividing such quotient by the aggregate number of
shares of VB Common Stock that are issued and outstanding or subject to
unexercised options on the Effective Date.  So long as the Average Closing
Price of WCB Common Stock is between $15.30 and $18.70 per share, the formula
is designed to result in VB shareholders receiving WCB Common Stock having a
market value of approximately $66.95 for each share of VB exchanged in the
Merger.



                                     - 21 -
<PAGE>   33
        The Average Closing Price is equal to the average of each Daily Sales
Price of WCB Common Stock for the ten consecutive trading days ending on and
including the fifth trading day preceding the Effective Date ("Pricing
Period").  But, the Average Closing Price in the Merger Agreement includes a
"floor" and a "ceiling" price, respectively 10% below and above a midpoint
price of $17 (representing the average closing price of WCB Common Stock prior
to the execution of the Merger Agreement).  Accordingly, if the average Daily
Sales Price over the Pricing Period is less than $15.30, the Average Closing
Price will be $15.30.  If, on the other hand, the Average Daily Sales Price
over the Pricing Period is greater than $18.70, the Average Closing Price will
be $18.70.

        The Modified Average Closing Price is the Average Closing Price not
subject to the "floor" price described above.  The Modified Average Closing
Price will be used in place of the Closing Price only if (i) the Average Daily
Sales Price over the Pricing Period is below $15.30 and has declined more than
5% in excess of any corresponding decline in a selected index of peer group
stock prices, (ii) VB is entitled to and does exercise its provisional right to
terminate the Merger Agreement under Subsection 7.2.5(a), and (iii) WCB removes
the limitation otherwise imposed by the "floor" as permitted by Subsection
7.2.5(b) of the Merger Agreement.  See "Termination of the Merger Agreement --
Decline in Value of WCB Stock."

        As an example of the operation of the formula for computing the
exchange ratio, recognizing the $11,581,000 Purchase Price, using the midpoint
price of $17 as the Average Closing Price, and assuming 172,984 shares of VB
Common Stock issued and outstanding or subject to unexercised options, the
number of shares of WCB Common Stock that will be exchanged for each share of
VB Common Stock would be determined as follows:  11,581,000 / 17 = 681,235.29 /
172,984 = 3.9381 shares of WCB Common Stock for each share of VB Common Stock.

        The following table sets forth examples showing the approximate number
of shares of WCB Common Stock a VB shareholder would receive in exchange for
100 shares of VB Common Stock.  The table is based upon various hypothetical
Average Closing Prices and assumes that 172,984 shares of VB Common Stock are
issued and outstanding or subject to unexercised options as of the Effective
Date.  On April 18, 1996, the price per share of the WCB Common Stock was
$18.25.  However, no assurance can be given as to the market value of WCB
Common Stock during the Pricing Period.

        number of shares issuable would continue to increase proportionately
        for values below $15.30 per share.

        The Merger will close and become effective on the Effective Date (as
defined in the Merger Agreement, within five business days after the
fulfillment or waiver of each condition set forth in the Merger Agreement),
unless extended by the parties.  Closing is anticipated by the summer of 1996.

Closing does not occur before October 31, 1996, either VB or WCB may terminate
the Merger Agreement.  See "THE MERGER  -- Conditions to the Merger."

CASH FOR FRACTIONAL SHARES

        WCB will not issue certificates for fractional shares of WCB Common
Stock.  Each VB shareholder who is otherwise entitled to receive a fractional
share, will receive cash in lieu thereof in an amount equal to the product of
such fraction multiplied by the Average Closing Price of WCB Common Stock, and
such VB shareholder will have no other rights with respect to such fractional
shares or other shares.

EXCHANGE OF STOCK CERTIFICATES

        On and after the Effective Date, certificates representing VB Common
Stock will be deemed to represent only the right to receive WCB Common Stock or
cash as provided in the Merger Agreement.  Upon surrender to the Exchange Agent
designated by WCB and VB, of certificates that, before the Effective Date,
represented shares of VB Common Stock, together with a properly executed
transmittal letter form and any other required documents, the holder
surrendering the certificates will be entitled to receive certificates
representing the number of shares of WCB Common Stock, and cash, if any, to
which he or she is entitled in accordance with the terms of the Merger
Agreement.  DO NOT SEND IN YOUR CERTIFICATES AT THIS TIME.  VB shareholders
will receive written instructions and the required letter of transmittal after
the Merger is effective.

        All WCB Common Stock issued pursuant to the Merger Agreement will be
deemed issued as of the Effective Date.  No distributions or dividends paid
upon shares of WCB Common Stock after the consummation of the Merger will be
paid to holders of VB Common Stock who are entitled under the Merger Agreement
to receive WCB Common Stock until such holders have surrendered the
certificates formerly representing shares of VB Common Stock, at which time any
accumulated dividends and distributions since the Effective Date, without
interest, will be paid.

DIRECTORS AND OFFICERS

        In connection with the Merger, WCB intends to appoint Mr. Pomajevich to
the WCB Board.  Mr. Pomajevich is currently the Chairman of the VB Board.  This
appointment will be effective on the Effective Date.  In addition, after the
Merger Mr. Stenseth will continue as the President of the Bank and, until the
end of his service as President, will be allowed to attend WCB Board meetings
as an ex-officio member of the WCB Board.

        The Bank's Board before the Merger will remain the same after the
Merger, except that an additional director (one of WCB's current directors)
will be appointed by WCB to the Bank's Board.  Consequently, on the Effective
Date, the Bank's Board will consist of all persons who were directors of the
Bank immediately before the Merger, plus a WCB director designated by WCB.  The
Bank's directors will serve until the 1997 annual meeting of the Bank's
shareholders or until their successors have been elected and qualified.  At the
1997 annual meeting of the Bank's shareholders, the directors then serving on
the Bank's Board may propose a slate of directors for election to the Bank's
Board until the 1998 annual meeting of the Bank's shareholders.  WCB, as the
Bank's sole shareholder, has agreed to elect the slate of directors proposed by
the outgoing VB directors in 1997, although WCB has the right to refuse to
elect any of the proposed directors if it has good cause for such refusal.

        As a condition to the execution of the Merger Agreement, each member of
the Board of VB entered into a Director Noncompetition Agreement with WCB, HB,
and VB.  Except under certain


                                     - 23 -
<PAGE>   35
limited circumstances, the Director Noncompetition Agreement prohibits these
directors from competing with WCB in Clackamas, Lincoln, Marion, Multnomah and
Washington Counties, Oregon and Clark County, Washington, for the lesser of (a)
two years after the director's service as a director of the Bank, WCB, or any
affiliate of WCB, is terminated or (b) three years from Closing of the Merger.

        As a further condition to the execution of the Merger Agreement, the
Bank entered into an employment agreement with Mr.  Stenseth, which was
ratified by WCB.  Under the employment agreement, Mr. Stenseth will continue as
President of the Bank after the Merger under the terms set forth in the
employment agreement.

EMPLOYEE BENEFIT PLANS

        The Merger Agreement confirms WCB's intention to allow the Bank's
employees who continue as employees of the Bank after the Merger to participate
in certain WCB employee benefit plans.  VB's employee benefit plans will be
terminated as soon as practical after the Merger, and the employee interests in
those plans will be transferred or merged into WCB's employee benefit plans.

MECHANICS OF THE MERGER

        On the Effective Date, VB will be merged with and into HB which itself
will be merged into WCB immediately after Closing.  At that time, all business,
assets, and liabilities formerly carried on or owned by VB will be transferred
to and vested in WCB.  VB will cease to have a corporate existence separate
from WCB, and the Bank will be a directly owned subsidiary of WCB.

CONDUCT PENDING CONSUMMATION OF THE MERGER

        The Merger Agreement provides that, until the Merger is effective, VB
will, and will cause the Bank to, conduct its business only in the ordinary and
usual course, and use all reasonable efforts to preserve its present business
organization, retain the services of its present management, and preserve the
goodwill of all parties with whom it has business dealings.  The Merger
Agreement also provides that, unless WCB otherwise consents in writing, VB will
refrain from engaging in various activities such as, effecting any stock split
or other recapitalization, disposing of assets or making material commitments,
acquiring real property without conducting an environmental evaluation, and
entering into transactions or incurring any expenses that are not in the
ordinary course of business.

CONDITIONS TO THE MERGER

        Consummation of the Merger is subject to various conditions.  No
assurance can be provided as to whether these conditions will be satisfied or
waived by the appropriate party.  Accordingly, there can be no assurance that
the Merger will be completed.  In the event that conditions to the Merger
remain unsatisfied and the Merger has not been effected on or before October
31, 1996, the Merger Agreement may be terminated by either party to the Merger
Agreement.

        The Merger can occur only if the holders of the shares of VB Common
Stock approve the transaction.  In accordance with VB's Articles of
Incorporation and Washington law, approval of the Merger requires the
affirmative vote by the holders of a majority of all shares outstanding.  In
addition, approval of the Merger Agreement is required from the FRB and the
Washington Director.  Applications are pending with both agencies.  Although no
assurance can be given, the parties expect to receive both approvals in due
course.


                                     - 24 -
<PAGE>   36
        Certain conditions must be satisfied or events must occur before the
parties will be obligated to complete the Merger.  Each party's obligations
under the Merger Agreement are conditioned on satisfaction by the other parties
of their conditions.  Some of these conditions are as follows: (a) the
representations and warranties of each party are true in all material respects
(as of Closing), and each party has complied with its covenants in the Merger
Agreement; (b) no Material Adverse Effect has occurred with respect to a party;
(c) each party's Board and VB's shareholders have approved the Merger; (d) WCB
has appointed, effective as of Closing, a VB director to serve on WCB's board
of directors; (e) the parties have provided one another with the counsel, tax,
accounting treatment, and fairness opinions required by the Merger Agreement;
(f) WCB has assumed or paid VB's note with Security State Bank and secured a
release from Security State Bank of VB's stock pledged as security for the
note; (g) the SEC has declared the effectiveness of the registration statement
for the shares of WCB common stock to be issued in the Merger; (h) VB and the
Bank have met certain financial condition requirements; (i) no action or
proceeding has been commenced or is threatened by any governmental agency to
restrain or prohibit or invalidate the Merger; (j) the aggregate of the cash to
be paid to VB shareholders in accordance with the Merger Agreement will not
exceed 10% of the value of the WCB common stock to be issued in the Merger; and
(k) all appropriate regulatory agencies have approved the Merger.

        Either WCB or VB may waive any of the other party's conditions, except
those that are required by law (such as receipt of regulatory and shareholder
approval).  Either WCB or VB may also grant extended time to the other party to
complete an obligation or condition.

AMENDMENT OF THE MERGER AGREEMENT

        The Merger Agreement may be amended or supplemented at any time by
written agreement of the parties, whether before or after the Meeting.  To the
extent permitted under applicable law, the parties may make any amendment or
supplement without further approval of VB's shareholders, except amendments
which would reduce the amount or change the form of consideration VB
shareholders will receive in the Merger transaction.

TERMINATION OF THE MERGER AGREEMENT

        The Merger Agreement contains several provisions entitling either VB or
WCB to terminate the Merger Agreement under certain circumstances.  The
following briefly describes these provisions:

        Lapse of Time.  If the Merger has not been consummated by October 31,
1996, then at any time after that date, either WCB or VB may terminate the
Merger Agreement if failure of the parties to consummate the Merger by October
31, 1996, was not due to the terminating party's breach of its obligations,
representations, or warranties under the Merger Agreement.

        Mutual Consent.  The parties may terminate the Merger Agreement at any
time before Closing, whether before or after approval by VB's shareholders, by
mutual consent.

        Failure of VB to Recommend Approval or Stock Option Becomes
Exercisable.  WCB may terminate the Merger Agreement before VB shareholders
approval if the VB Board fails to recommend (or adversely modifies, withdraws
or changes its recommendation) approval of the merger to its shareholders.  WCB
may also terminate the Merger if the Option under the Stock Option Agreement
becomes exercisable by WCB, unless WCB has exercised such Option.

        Decline in Value of WCB Stock.  VB has certain rights, tied to a
reduction in value of WCB Common Stock, to terminate the Merger Agreement
during the three-business-day period beginning five


                                     - 25 -
<PAGE>   37
calendar days before the Effective Date of the Merger.  These termination
rights are generally subject to WCB's right to avoid termination by increasing
the number of WCB shares VB shareholders will receive (the so-called "right to
fill").  However, VB may terminate the Merger Agreement, and WCB has no right
to avoid termination, if, during the three-business-day period identified
above, the Modified Average Closing Price is less than $13.60.

        Impracticability.  Either WCB or VB may terminate the Merger Agreement
upon written notice to the other parties if its Board determines, in good faith
and after due consultation with counsel, that the Merger is inadvisable or
impracticable by reason of the institution of litigation by the federal
government or the governments of Washington or Oregon to restrain or invalidate
the transactions contemplated by the Merger Agreement.

        Allocation of Costs Upon Termination.  If the Merger Agreement is
terminated, WCB and VB will each pay their own out-of- pocket costs incurred in
connection with the transaction, and will have no other liability to any other
party.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

        Certain members of the VB Board and management may be deemed to have
interests in the Merger, in addition to their interests as shareholders of VB.
The VB Board was aware of these factors and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby.

        Employment Agreement.  WCB has ratified an employment agreement entered
into between the Bank and Mr. Stenseth, President of the Bank.  The term of the
employment agreement begins on the Effective Date and ends on May 31, 1998.
The Bank may terminate the agreement at any time for cause without incurring
any post-termination obligation to Mr. Stenseth, or without cause, in which
case the agreement provides severance benefits.  Mr. Stenseth is generally
prohibited from competing with WCB in its market area for the lesser of (a) two
years after termination or (b) three years from the Effective Date.

        Appointments to the WCB Board.  WCB has also agreed to appoint Mr.
Pomajevich, currently the Chairman of the VB Board, to the WCB Board, effective
on Closing.  In addition, Mr. Stenseth will be allowed to attend WCB Board
meetings as an ex-officio member, until the end of his service as President of
the Bank.  Finally, the current directors of the Bank will continue to serve as
directors following the Merger.

CERTAIN FEDERAL INCOME TAX MATTERS

        The Merger is intended to qualify as a tax-free reorganization under
Section 368(a) of the Code for federal income tax purposes.  VB and WCB will
receive at Closing an opinion from Graham & Dunn, P.C. that the Merger will
constitute a tax-free reorganization for federal tax purposes.  Such opinion
will not bind the Internal Revenue Service or preclude the Internal Revenue
Service from adopting a contrary position.  The opinion is based upon facts and
assumptions and representations and assurances made by VB and WCB.  THE FEDERAL
INCOME TAX DISCUSSION SET FORTH BELOW MAY NOT APPLY TO PARTICULAR CATEGORIES OF
HOLDERS OF VB COMMON STOCK SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL
INCOME TAX LAWS, SUCH AS FOREIGN HOLDERS OR HOLDERS WHOSE STOCK MAY HAVE BEEN
ACQUIRED AS COMPENSATION.  IN ADDITION, THERE MAY BE RELEVANT STATE, LOCAL OR
OTHER TAX CONSEQUENCES, NONE OF WHICH ARE DESCRIBED BELOW.  SHAREHOLDERS ARE
URGED TO CONSULT THEIR ADVISORS TO DETERMINE THE SPECIFIC PERSONAL TAX
CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN,
STATE, LOCAL, AND OTHER TAX LAWS.


                                     - 26 -
<PAGE>   38
        The Graham & Dunn, P.C. opinion will state that:

        1.       The merger of VB with and into HB will constitute a tax-free
                 reorganization.

        2.       No gain or loss will be recognized by either VB or WCB as a
                 result of the Merger.

        3.       The tax basis and holding period for the VB assets that are
                 received by WCB in the Merger will be the same as the tax
                 basis and holding period of the assets held immediately before
                 the exchange by VB.

        4.       No gain or loss will be recognized by holders of VB Common
                 Stock upon the receipt of WCB Common Stock in exchange for VB
                 Common Stock pursuant to the Merger.

        5.       The tax basis of the WCB Common Stock received in the Merger
                 by VB shareholders will be the same as the tax basis of the
                 shares of VB Common Stock surrendered in the exchange, reduced
                 by any basis allocable to a fractional share interest in the
                 WCB Common Stock for which cash is received.  The holding
                 period for the shares of WCB Common Stock received in the
                 Merger will include the holding period of VB shares exchanged,
                 provided that VB shares were held as capital assets at the
                 time of the Merger.

        6.       Gain or loss will be recognized by VB shareholders who receive
                 cash in lieu of fractional shares of WCB Common Stock, or who
                 exercise dissenters' rights and receive cash for their shares.
                 The amount of such gain or loss will be the difference between
                 the cash received and the basis of the shares or fractional
                 share interests surrendered in the exchange.  Such gain or
                 loss will be a capital gain or loss provided that the shares
                 of VB Common Stock surrendered were capital assets at the time
                 of surrender, and will be long-term capital gain or loss if
                 such shares of VB have been held for more than one year.

ACCOUNTING TREATMENT OF MERGER

        It is anticipated that the Merger will be accounted for as a pooling of
interests for accounting purposes.  Under this method of accounting, assets and
liabilities of VB and WCB are carried forward at their previously recorded
amounts, and operating results of WCB and VB will represent the combined
results for periods before and after the Merger.  No recognition of goodwill
arising from the Merger is required of any party to the Merger.  Under the
Merger Agreement, receipt of a letter from Arthur Andersen LLP that the Merger
will qualify for the pooling of interests treatment is a condition to the
obligation of WCB to consummate the Merger.

        The unaudited condensed pro forma combined financial information
contained in this Prospectus/Proxy Statement has been prepared using the
pooling of interests accounting method to account for the Merger.  See
"UNAUDITED CONDENSED PRO FORMA COMBINED FINANCIAL STATEMENTS," including the
related Notes.


                                     - 27 -
<PAGE>   39
DISSENTERS' RIGHTS OF APPRAISAL

        Under Washington state law (RCW 23B.13), a shareholder of VB may
exercise "dissenters' rights" and receive the fair value of his or her shares
in cash, if certain procedures are followed.  To exercise these rights, a VB
shareholder must (1) deliver to VB, before the vote on approval of the Merger
is taken, written notice of intent to demand payment for his or her shares if
the Merger is effected, and (2) not vote in favor of the Merger.  Following
consummation of the Merger, WCB will send a Dissenters' Notice to each VB
shareholder who has properly perfected his or her dissenters' rights.  A
dissenting shareholder must also follow the procedures set forth in the
Dissenters' Notice.  The Dissenters' Notice will include instructions to
completing the exercise of dissenters' rights, including that the dissenting
shareholder must (1) make written demand for payment of the fair value of his
or her shares in the form sent to the shareholder by the corporation along with
the Dissenters' Notice (this notice will prescribe a time period within which
the demand must be made), (2) certify that beneficial ownership of his or her
VB Common Stock shares was acquired before the date set forth in the
Dissenters' Notice, and (3) surrender his or her stock certificates
representing shares of the VB Common Stock in accordance with the Dissenters'
Notice.  If a shareholder exercises dissenters' rights, the dissenting
shareholder is entitled to receive the fair value of his or her shares in cash.
Such value may be higher or lower than the value of WCB Common Stock issuable
pursuant to the Merger Agreement.

        The failure of a shareholder of VB to comply strictly with the
statutory requirements will result in a loss of dissenters' rights.  A copy of
the relevant statutory provisions is attached as Appendix C.  VB shareholders
should refer to this Appendix for a complete statement concerning dissenters'
rights, and the foregoing summary of such rights is qualified in its entirety
by reference to such Appendix C.

RESALES OF STOCK RECEIVED IN THE MERGER BY VB AFFILIATES

        The WCB Common Stock to be issued in the Merger will be transferable
free of restrictions under the Securities Act, except for shares received by
persons, including directors and executive officers of VB, who may be deemed to
be "affiliates" of VB, as that term is used in (i) paragraphs (c) and (d) of
Rule 145 under the Securities Act and/or (ii) Accounting Series Releases 130
and 135, as amended, of the SEC.  Affiliates may not sell their shares of WCB
Common Stock acquired pursuant to the Merger, except (a) pursuant to an
effective registration statement under the Securities Act covering those
shares, (b) in compliance with Rule 145, or (c) in the opinion of counsel
reasonably satisfactory to WCB, pursuant to other applicable exemptions from
the registration requirements of the Securities Act.  SEC guidelines further
indicate that the pooling of interests method of accounting will generally not
be challenged on the basis of sales by affiliates of the acquiring or acquired
company if such affiliates do not dispose of any of the shares of the acquiring
or acquired company they owned before the consummation of a merger or shares of
the acquiring corporation they receive in connection with the merger during the
period beginning 30 days before the merger and ending when financial results
covering at least 30 days of post-merger operations of the combined
organization have been published.  WCB has obtained customary agreements with
all VB directors, officers, and affiliates of VB and WCB, under which such
persons have represented that they will not dispose of their shares of WCB
received in the Merger or the shares of capital stock of VB or WCB held by them
before the Merger, except (i) in compliance with the Securities Act and the
rules and regulations promulgated thereunder, and (ii) in a manner that would
not adversely affect the ability of WCB to treat the Merger as a pooling of
interests for financial reporting purposes.  This Prospectus/Proxy Statement
does not cover any resales of the WCB Common Stock received by affiliates of
VB.


                                     - 28 -
<PAGE>   40
NO SOLICITATION

        VB has agreed in the Merger Agreement that, except as required by law,
neither VB nor any of its officers or directors will (i) solicit, encourage,
entertain or facilitate any other proposals or inquiries for an acquisition of
the shares or assets of VB or its subsidiaries, (ii) enter into discussions
concerning any such acquisition, or (iii) furnish any nonpublic information
relating to WCB's business or organization to any person that is not affiliated
with VB or WCB.

EXPENSES

        WCB and VB will each pay their own expenses in connection with the
Merger Agreement and the transactions contemplated thereby, except that
printing expenses for this Prospectus/Proxy Statement will be shared by both
parties.

STOCK OPTION AGREEMENT

        As a condition to WCB's willingness to enter into the Merger Agreement,
and in consideration thereof, VB issued to WCB an irrevocable Option to
purchase, under certain conditions, up to 28,144 shares of VB Common Stock at a
price of $64.00 per share, subject to adjustment in certain circumstances, such
as in the event of issuance of additional shares (other than pursuant to stock
options).  The Option was granted to WCB pursuant to the Stock Option Agreement
between WCB and VB dated as of February 15, 1996.  The number of shares of VB
Common Stock subject to the Option represents approximately 19.9% of the
outstanding shares of VB Common Stock as of February 15, 1996, before giving
effect to the issuance of such shares.

        Prior to exercising the Option, WCB will not have any voting rights
with respect to the shares of VB Common Stock subject to the Option.  WCB may
exercise the Option only upon the occurrence of certain events (described
below) and obtaining any regulatory approvals necessary for the acquisition of
the VB Common Stock subject to the Option.  To WCB and VB's knowledge, no event
which would permit the exercise of the Option has occurred as of the date of
this Prospectus/Proxy Statement.  At the request of WCB, under limited
circumstances, VB will repurchase for a formula price the Option and any shares
of VB Common Stock purchased upon exercise of the Option and beneficially owned
by WCB at that time.

        WCB may not exercise the Option during any period in which it is
failing in any material respect to perform its obligations or observe its
covenants under the Merger Agreement, unless the reason for such failure is
that VB is failing in any material respect to perform its obligations or
observe its covenants under the Merger Agreement.  Further, WCB may not
exercise the Option if any governmental approvals required for the issuance of
the shares of VB Common Stock to be purchased under the Option have not been
obtained, or the issuance would violate applicable laws or regulations.
Otherwise, WCB may exercise the Option in whole or in part, but only if both an
Initial Triggering Event (defined below) and a Subsequent Triggering Event
(defined below) occur before the occurrence of an Exercise Termination Event
(defined below).  WCB must notify VB in writing of its intention to exercise
the Option within 30 days after the Subsequent Triggering Event, or such longer
period as provided in the Stock Option Agreement.

        The term "Initial Triggering Event" means any of the following events
or transactions which occurs after February 15, 1996:

        (i)      VB or any of its subsidiaries taking certain actions (each an
"Acquisition Transaction"), including authorizing, recommending or entering
into an agreement with any third party, without WCB's



                                     - 29 -
<PAGE>   41
prior written consent, to effect (a) a merger, consolidation or similar
transaction involving VB or any of its significant subsidiaries, (b) a sale,
lease or other disposition of all or substantially all of the assets of VB or
any of its significant subsidiaries, (c) a sale or other disposition (including
by way of merger, consolidation, share exchange or otherwise) of securities
representing 15% or more of the voting power of VB or any of its significant
subsidiaries, or (d) a transaction substantially similar to any of the
foregoing;

        (ii)     A third party acquiring or having the right to acquire an
aggregate of 15% or more of the outstanding shares of VB Common Stock;

        (iii)    A third party making a bona fide proposal to VB or its
shareholders by public announcement or written communication that becomes the
subject of public disclosure to engage in an Acquisition Transaction;

        (iv)     After a proposal is made by a third party to VB or its
shareholders to engage in an Acquisition Transaction, VB breaching any covenant
or obligation contained in the Merger Agreement that would entitle WCB to
terminate the Merger Agreement and is not cured during the period provided; or

        (v)      A third party filing an application or notice with the Federal
Reserve Board or other federal or state bank regulatory authority, that is
accepted for processing, for approval to engage in an Acquisition Transaction.

        The term "Subsequent Triggering Event" means either of the following
events or transactions which occurs after February 15, 1996, such an event also
constituting an Initial Triggering Event:

        (i)      A third party acquiring beneficial ownership of 25% or more of
the then outstanding shares of VB Common Stock; or

        (ii)     VB or any of its subsidiaries taking certain actions,
including authorizing, recommending or entering into an agreement with any
third party, without WCB's prior written consent, to effect (a) a merger,
consolidation or similar transaction involving VB or any of its significant
subsidiaries, (b) a sale, lease or other disposition of all or substantially
all of the assets of VB or any of its significant subsidiaries, (c) a sale or
other disposition (including by way of merger, consolidation, share exchange or
otherwise) of securities representing 25% or more of the voting power of VB or
any of its significant subsidiaries, or (d) a transaction substantially similar
to any of the foregoing.

        The term "Exercise Termination Event" means the earliest to occur of
the following: (a) the Effective Date of the Merger; (b) termination of the
Merger Agreement in accordance with its terms  (with certain limited
exceptions, before the occurrence of an Initial Triggering Event); (iii) 12
months after the termination of the Merger Agreement, if the termination
follows the occurrence of an Initial Triggering Event (or a termination by WCB
under certain circumstances); (iv) the second anniversary of the date of the
Stock Option Agreement (that is, February 15, 1998); or (v) the exercise by WCB
of its right to terminate the Merger Agreement under a certain provision of the
Merger Agreement.

        Anti-Dilution Provisions.  In addition to typical antidilution
provisions which protect against the effects of stock dividends, stock splits
and other similar transactions, the Option provides that if the additional
shares are issued, the number of shares which may be purchased under the Option
will increase to maintain WCB's purchase percentage at 19.9, and, unless those
shares are issued pursuant to a pre-existing agreement (such as the outstanding
stock options), the exercise price will be adjusted so that the



                                     - 30 -
<PAGE>   42
aggregate price paid by WCB will be the same.  This is the case even if the new
shares are issued for market value consideration.

        Registration Rights.  If the right to exercise the Option is triggered,
WCB has the right to request registration of the shares to be issued to it
under the Securities Act.  Should registration be required, it would result in
a significant expense, both in connection with the initial registration and
because VB would then be subject to ongoing reporting under the Exchange Act.

        Repurchase of Option or Option Shares.  In the event the right to
exercise the Option is triggered, WCB or the owner of the shares received in
exercise of the Option will have the right to require VB to repurchase the
Option or the shares.  The repurchase price is to be based upon the highest of
the following during the preceding six months:  (a) the price at which a tender
or exchange offer has been made; (b) the price paid, or agreed to be paid, by a
third party for VB shares; (c) the highest closing market price; and (d) in the
event of an asset sale, a price based upon the price paid for the assets sold
plus the value of the remaining assets as determined by a nationally recognized
investment banking firm selected by WCB or the owner of the shares (the
"Market/Offer Price").

        Substitute Option.  In the event of a merger in which VB is not the
surviving entity, a merger in which VB is the surviving entity but increases
the number of its shares outstanding by more than 50 percent, or a sale of all
or substantially all of the assets of VB, WCB is entitled to a Substitute
Option in VB (if it is the surviving entity), the acquiring company or a person
in control of the acquiring company, selected at WCB's option.  The number of
shares is to be based upon the product of the number of shares then covered by
the Option multiplied by the Market/Offer Price (computed as described in the
preceding paragraph) divided by a computed average price for the entity in
which the Substitute Option is granted.  This could result in a number of
shares different from those received by other shareholders.  The exercise price
for the Substitute Option will be adjusted based on the difference in the
number of shares for which the initial Option is exercisable as compared to the
number of shares for which the Substitute Option is exercisable.  If the effect
of this computation would be to give a Substitute Option for more than 19.9
percent of the surviving entity, the Substitute Option will only be for 19.9
percent, but WCB would be entitled to a cash payment for the value of the
reduction.  The Substitute Option would be subject to standard antidilution
provisions, but not the additional price adjustments for the original Option.

        The Stock Option Agreement and the Option are intended to compensate
WCB in the event that that the Merger is not consummated according to the terms
set forth in the Merger Agreement, and may have the effect of discouraging
competing offers to acquire VB from potential third party acquirors because the
Option could increase the cost of such an acquisition.  A copy of the Stock
Option Agreement is set forth as Appendix B to this Prospectus/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.

                     NOTES TO UNAUDITED PRO FORMA COMBINED
                              FINANCIAL STATEMENTS

1.      Intangibles

        Core deposit intangibles of $283,290 at WCB are being amortized over
        seven and ten year lives with approximately six years remaining.

2.      Adjustments

        The unaudited pro forma combined balance sheet reflects the issuance of
        WCB Common Stock, no par value, as the issuance of 552,141 shares to VB
        shareholders using the exchange ratio of 3.9381, in addition to the
        4,804,441 shares already outstanding to WCB's shareholders.  These
        shares were derived by using the respective company's outstanding
        shares at December 31, 1995.  An adjustment of $549,971 to common stock
        and capital surplus is necessary to reflect the difference between
        issuance of 552,141 shares of WCB Common Stock, no par value, with an
        aggregate par value of $690,176 and the value of VB Common Stock that
        will be canceled which is $141,461.  The pro forma adjustments were
        based on the midpoint of the proposed exchange ratio collar generating
        the issuance of 552,141 shares.  The estimated maximum number of shares
        to be issued would be 613,495 (except under certain circumstances) and
        the estimated minimum number of shares to be issued would be 501,947,
        based on December 31, 1995 financial information.  There were no other
        significant adjustments made to the historical balance sheets or
        statements of income of WCB and VB to arrive at the unaudited pro forma
        combined balance sheets.

3.      Transaction Costs

        Total costs to be incurred by WCB and VB in connection with the Merger
        are estimated to be $300,000.  These costs, relating to legal,
        accounting, printing and other related expenses, will be charged
        against net income of the combined organization in the period incurred.
        The effect of the costs has not been reflected in the Pro Forma
        Combined Financial Statements.

                           INFORMATION CONCERNING WCB

        WCB is a bank holding company headquartered in Lake Oswego, Oregon,
eight miles south of downtown Portland.  The community banking organization
currently comprises three member banks, The Bank of Newport, The Commercial
Bank, and Valley Commercial Bank, and has long-standing roots in Oregon dating
back to 1925.  A broad range of community banking services are offered
throughout the 28-office network stretching from Portland south along I-5 to
the greater Salem area and west to the central Oregon Coast.

        WCB's expansion plans include internally-generated growth from
strategically-located existing branches, some selected new branch expansion and
expansion into southwest Washington.  In addition to limited de novo branching,
WCB's management strategy has also been to pursue attractive alliance
opportunities with other well-run community banks such as the proposed
transaction with VB, as well as other financial service related companies.  In
June 1994, WCB concluded a successful offering of the WCB Common Stock, which
contributed over $5 million in additional capital to help finance WCB's
expansion plans.  During the interim period, WCB has continued to invest
significantly in management, technology, and other resources (such as a new
data center) to support its expansion.

        Financial and other information regarding WCB, including information
relating to WCB's directors and executive officers, are set forth in the WCB
1995 10-K and the WCB 1996 Proxy incorporated by reference herein.  See
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and "AVAILABLE INFORMATION."

                           INFORMATION CONCERNING VB
BUSINESS

        VB was organized under Washington law in 1994 for the purpose of
becoming a holding company of the Bank, under an agreement and plan of exchange
pursuant to which shareholders of the Bank became shareholders of VB.  VB is
registered with the Board of Governors of the Federal Reserve System as a bank
holding company under the BHCA, and has no significant operations separate from
the Bank.  The principal offices of VB are located at the main office of the
Bank at 801 Main Street, Vancouver, Washington.

        The Bank is a state-chartered bank organized under Washington law in
June 1989.  It engages in commercial banking activities from its sole office
located at 801 Main St., Vancouver, Washington.  The Bank was organized to meet
a perceived need for the services of a local community bank with a commitment
to service to the businesses and residents of Clark County, Washington.  The
Bank offers commercial banking services, primarily to small- and medium-size
businesses, professionals and retail customers, including commercial loans,
accounts receivable and inventory financing, consumer installment loans,
acceptance of deposits, and personal savings and checking accounts.  The Bank
offers residential mortgage loans in association with PHW Mortgage Co.

        The Bank's accounts are insured by the FDIC.  As of December 31, 1995,
the Bank had deposits of approximately $70.7 million and assets of
approximately $78.9 million.

COMPETITION

        Competition in the banking industry is significant and has intensified
with interest rate deregulation.  Furthermore, competition from outside the
traditional banking system from investment banking firms, insurance companies
and related industries offering bank-like products has widened the competition
for deposits and loans.


                                     - 38 -
<PAGE>   50
        The banking industry in the Bank's primary market area is characterized
by well-established branches of large banks with headquarters located generally
outside the primary market area.

        The Bank's traditional competition for deposits comes from commercial
banks, savings and loan associations, credit unions, and money market funds,
many of which have more locations or offer higher rates of interest than the
Bank.  Competition for funds also comes from issuers of corporate and
governmental securities, insurance companies, mutual funds, and other financial
intermediaries.  Other than with respect to large certificates of deposit, the
Bank competes for deposits by offering a variety of deposit accounts at rates
generally competitive with similar financial institutions in the area.  The
Bank's principal competitive advantage with respect to the larger state-wide
financial institutions is its status as a local community bank, offering
products and services tailored to the needs of the community.  In addition, as
a result of the absence of costs associated with operating a branch system, the
Bank, operating from just one office, can and sometimes does pay a higher rate
on deposits.

        In competing for deposits, the Bank is subject to certain limitations
not applicable to non-bank competitors.  Legislation enacted in the 1980s
authorized banks to offer deposit instruments with rates competitive with money
market funds, but subject to restrictions not applicable to those funds.
Legislation has also made non-bank financial institutions more effective
competitors.  Savings and loan associations and credit unions are now permitted
to offer checking accounts and to make commercial loans with certain
limitations.

        The Bank's competition for loans comes primarily from the same
financial institutions with which the Bank competes for deposits.  The Bank
competes for loan originations primarily through the level of interest rates
and loan fees charged, the variety of commercial and mortgage loan products
offered, and the efficiency and quality of services provided to borrowers.
Factors which affect loan competition include the availability of lendable
funds, local and national economic conditions, current interest rate levels,
and loan demand.  The Bank does not engage in mortgage banking activities, and
loan origination for mortgage loans is limited by the Bank's regulatory lending
limits.

        The offices of the major banks and savings and loan associations have
competitive advantages over the Bank in that they have high public visibility
and are able to maintain advertising and marketing activity on a much larger
scale than the Bank can economically maintain.  Because single borrower lending
limits imposed by law are dependent on the capital of the institution, the
branches of larger institutions with substantial capital bases are also at an
advantage with respect to loan applications which are in excess of the Bank's
legal lending limits.

        At present, there are five commercial banks, five thrifts and 19 credit
unions operating in the Bank's market area which offer some of the services
offered by the Bank, and which may be in direct competition for the customers
which the Bank seeks to attract.  Because of the extensive experience of
management of the Bank in its trade area and the business contacts of
management and the directors, management believes that the Bank is able to
compete effectively for business.

FACILITIES

        The principal offices of VB are located at the main office of the Bank
at 801 Main Street, Vancouver, Washington.  Approximately 14,400 square feet of
space, constituting the Bank's premises, are leased by the Bank pursuant to
three leases, for an aggregate monthly rate of $13,975.50.  The leases expire
on January 31, 2001.


                                     - 39 -
<PAGE>   51
        The Bank owns the building in which its former office was located at
109 E. 13th St., Vancouver, Washington, subject to a ground lease which expires
in the year 2015 and carries a monthly rent of $750.  The building is leased to
Washington Mutual, Inc. at a monthly rent of $6,250.00.

EMPLOYEES

        As of March 31, 1996, the Bank had 34 full-time equivalent employees.
VB has no employees separate from those of the Bank.  The employees are not
represented by a union organization or other collective bargaining group, and
management considers its relations with the employees to be very good.

LEGAL PROCEEDINGS

        The Bank is from time to time a party to various legal proceedings
arising in the ordinary course of the Bank's business.  Management believes
that there is no threatened or pending proceedings against VB or the Bank
which, if determined adversely would have a material effect on the business or
financial position of either, respectively.

                   VB MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following discussion of VB's consolidated financial condition and
results of operations is intended to be read in conjunction with, and is
qualified in its entirety by reference to, the selected consolidated financial
and other data, the consolidated financial statements and relates notes
included elsewhere in this Prospectus/Proxy.

        General.  The Bank's business consists primarily of attracting deposits
from the public and originating commercial and real estate loans.  The Bank's
net income is derived principally from net interest income.  The Bank exceeded
all of its regulatory capital requirements at December 31, 1995.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        Years ended December 31, 1995 and 1994

        Overview.  Total assets of $78.9 million as of December 31, 1995,
represents a 23.4% increase over total assets of $64.0 million as of December
31, 1994.  Most of the growth is a result of the increases within the loan
portfolio.

        Net Income.  For the years ended December 31, 1995 and 1994, VB's net
income was $891,000 and $664,000, respectively.  Income increased $227,000, or
34.2% from 1995 to 1994.  Earnings per share for the two years ended 1995 were
$6.10 and $4.71, respectively.

        Net Interest Income.  During the years ended December 31, 1995 and
1994, average interest earning assets grew to $66.6 million, from $50.9
million.  For the same periods, average interest bearing liabilities were $55.1
million and $41.2 million, respectively.  During the same periods, net interest
margins decreased to 4.34% from 4.50%, due mainly to a rising interest rate
environment and an increase of high yield savings accounts.  Net interest
income increased $839,000 or 31.1% to $3.5 million in 1995 from $2.7 million in
1994.  The increased net interest income was caused by the offsetting factors
of increased asset growth and a declining net interest spread.  This represents
an increase of 30.8% in 1995 from 1994.  The average yield earned on interest
earning assets increased to 10.01% in 1995 from 8.70% in 1994.  For the same
periods, average rates paid for interest-bearing liabilities increased from
4.20% to 5.67% in 1995.

        Average Balances and Average Rates Earned and Paid.  The following
table sets forth, for the periods indicated, information with regard to average
balances of assets and liabilities, the total dollar amounts in interest income
on interest earning assets and interest expense on interest bearing
liabilities, resulting yields or costs, net interest income, and net interest
margin.  Loan fees are recognized as income using the interest method over the
life of the loan.

        Non-Interest Expenses.  Non-interest expenses for the year ended
December 31, 1995, increased $525,000, or 30.66%, from 1994.  The 1995 increase
is due primarily to increased personnel and occupancy costs associated with the
Bank's move to a new facility as well as continued growth in loans and
deposits.  Loans increased $19.3 million, or 45.77%, to $61.4 million in 1995
from $42.1 million in 1994.

        Provision for Loan Losses.  The allowance for loan losses represents
management's current estimate of amounts required to absorb losses on existing
loans.  The $848,207 allowance at December 31, 1995, is an increase of
$297,110, or 53.9%, from the 1994 allowance of $551,097.  The allowance
represents 1.39% of total loans at December 31, 1995, as compared to 1.31% at
December 31, 1994.  Determination of the appropriate allowance level is based
on, among other things, an analysis of various factors including historical
loss experience based on volumes and types of loans, volumes and trends in
delinquencies and non- accrual loans, trends in portfolio volume, results of
internal and independent external credit reviews, and anticipated economic
conditions in the Bank's market area.  Based on this analysis, management
considers the allowance for possible loan losses to be adequate.

        Liquidity and Sources of Funds.  The Bank's primary sources of funds
are customer deposits, maturities of investment securities, sales of "available
for sale" securities, loan repayments, net income, and advances from the
Federal Home Loan Bank of Seattle (FHLB).  Scheduled loan repayments are
relatively stable sources of funds while deposit inflows and unscheduled loan
prepayments are not.  Deposit inflows and unscheduled loan prepayments are
influenced by general interest rate levels, interest rates available on other
investments, competition, economic conditions, and other factors.

        Total deposits were $70.7 million at December 31, 1995, up from $57.6
million at December 31, 1994.  The Bank does not generally accept brokered
deposits.  A concerted effort has been made to attract deposits in the market
area it serves through competitive pricing and delivery of quality products.

        Management anticipates that the Bank will continue relying on customer
deposits, maturity of investment securities, sales of "available for sale"
securities, loan repayments, net income and FHLB borrowings to provide
liquidity.  Although deposit balances have shown historical growth, such
balances may be influenced by changes in the banking industry, interest rates
available on other investments, general economic conditions, competition and
other factors.  Borrowings may be used on a short-term basis to compensate for
reductions in other sources of funds.  Borrowings may also be used on a
long-term basis to support expanded lending activities and to match maturities
or repricing intervals of assets.  The sources of such funds will most likely
be borrowings from the FHLB.

        Capital.  The primary capital-to-asset leverage ratio for the Bank was
8.95% at December 31, 1995, as compared to 9.59% at December 31, 1994.  In
1989, the banking regulators adopted risk based capital guidelines under which
one of four risk weights is applied to balance sheet assets, each with
different capital requirements based on the credit risk of the asset.
Risk-adjusted capital-to-asset ratios were 11.45% and 13.90% at December 31,
1995 and 1994, respectively.  As of December 31, 1995, the Bank was considered
"Well Capitalized" per regulatory risk based capital guidelines.

        As the following table indicates, the Bank currently exceeds the
regulatory minimum capital ratio requirements.

LENDING

        The Bank's principal lending activity is the origination of commercial
real estate and real estate construction loans.  The Bank's policy is to
originate loans primarily in its local market area.

        The Bank's loan underwriting policies focus on assessment of each
borrower's ability to service and repay the debt, and the availability of
collateral that can be used to secure the loan.  Depending on the nature of the
borrower and the purpose and amount of the loan, the Bank's loans may be
secured by a variety of collateral, including business assets, real estate and
personal assets.  Many business loans may also be dependent upon the personal
guarantees of owners of the business.  The Bank's loans are generally
classified by the ability of the borrower to repay and the principal asset
pledged as collateral to secure the loan.

        The Bank's commercial and industrial loans consist primarily of secured
revolving operating lines of credit and business term loans.  Commercial real
estate loans include loans for various purposes where the primary collateral is
commercial real estate.  Real estate construction loans include loans made in
connection with custom and "spec" (build to sell) construction of residential
and commercial buildings and loans made to borrowers who build residential and
commercial buildings for resale.  The majority of loans within the Bank's
portfolio have terms of five years or less or have adjustable interest rates.
Such rates are principally tied to the prime rate, or to a similar extent, a
treasury-base index.

        Consumer installment loans and other loans, while representing a small
percentage of total outstanding loans, include home equity loans, auto loans
and Visa cards.

        In addition to interest earned on loans, the Bank receives fees for
originating loans and for providing loan commitments.  These fees, net of costs
to originate the loans, are deferred and amortized into interest income over
the life of the loan.  Loans are originated principally as a result of contact
with and referrals from existing customers and through the efforts of Bank
staff.

        Types of Loans.  The following table sets forth the composition of the
Bank's loan portfolio by type of loan as of the date indicated.  The
composition of loans at December 31 was as follows:

</TABLE>

Interest income on non-accrual loans that would have been recorded in the
period ended December 31, 1995, was $18,657.  Interest income collected on such
loans and included in income was $20,285.  Past due loans continue to be
minimal.

        Loan Administration.  With the Bank's primary lending focus on
commercial, commercial real estate and real estate construction, risk is
generally correlated with the health of the business community.  The risk is
mitigated by monitoring the financial condition of the Bank's customers, and by
maintaining adequate collateral margins.  The Bank has adopted comprehensive
lending policies that provide detailed underwriting guidelines, as well as
procedures for the identification and monitoring of potential problem loans.
The loan committee meets regularly and reviews various reports pertaining to
the performance, quality and composition of the loan portfolio, as well as
detailed credit information regarding new loans extended during the period.
The VB Board, as a whole, serves as the loan committee.

<PAGE>   58
        Non-Performing Loans.  Accrual of interest on loans is discontinued
when reasonable doubt exists as to the collectibility of the loan or the unpaid
interest, or when payment of principal or interest is contractually 90 days
past due, unless the loan is well secured and in the process of collection.
Upon such discontinuance, the loan is placed on non-accrual status and any
accrued but unpaid interest is charged against income in that period.  Accrual
of interest is resumed only when the borrower demonstrates an ability to make
scheduled payments of both principal and interest.

        At December 31, 1995, there were no commitments to lend additional
funds to borrowers whose loans were classified as non-accrual.  The Bank is not
aware of any loans that continue to accrue interest at December 31, 1995, that
management reasonably expects will have a materially negative impact on future
operating results.  The Bank's management is not aware of any information
concerning any material loans, other than those discussed as risk elements
above, that causes them to have doubts as to the ability of the borrowers to
comply with the terms of the loans.

SUMMARY OF LOAN LOSS EXPERIENCE

        Analysis of Allowance for Loan Losses.  The Bank maintains the
allowance for loan losses at a level sufficient to provide for estimated loan
losses based on evaluating known and inherent risks in the loan portfolio.
Management determines the adequacy of the allowance based on reviews of
individual credits, recent loss experience, current economic conditions, the
risk characteristics of classified loans, and other pertinent factors.  Credits
deemed uncollectible are charged to the allowance.  Provisions for credit
losses and recoveries on loans previously charged off loans are added to the
allowance.  The following is an analysis of the activity in the allowance for
loan losses for the years ended December 31, 1995 and 1994:

        Asset and Liability Management.  The Bank's results of operations
depend substantially on net interest income.  Interest income and interest
expense are affected by general economic conditions, competition in the market
place, market interest rates and repricing and maturity characteristics of the
Bank's assets and liabilities.

        Exposure to interest rate risk is primarily a function of differences
between the maturity and repricing schedules of assets (principally loans and
investment portfolio securities) and liabilities (principally deposits).
Assets and liabilities are described as interest sensitive for a given period
of time when they mature or can reprice within that period.  The difference
between the amount of interest sensitive assets and interest sensitive
liabilities is referred to as the interest sensitivity "GAP" for any given
period of time.

        As a general rule, in periods of falling interest rates, banks with
positive interest sensitivity GAPs are more susceptible to a decline in net
interest income.  In periods of rising interest rates, banks with negative
interest sensitivity GAPs are more likely to experience declines in net
interest income.  The actual effect that rising and falling interest rates have
on the Bank's net interest income depends, however, not only on the interest
sensitivity GAP, but also the relative changes in interest rates that occur
when assets and liabilities are repriced, unscheduled repayments of loans,
early withdrawals of deposits and other factors.

        As of December 31, 1995, the Bank had a negative interest sensitivity
GAP and thus is most vulnerable to rising interest rates.  Bank management
attempts to limit exposure to interest rate risk by maintaining a balance sheet
posture such that net interest income is not significantly affected by market
fluctuations in interest rates.  The Bank utilizes interest sensitivity GAP
reports in conjunction with simulation modeling to measure the effect of
varying interest rate scenarios and balance sheet strategies on net interest
income.

        Certain shortcomings are inherent in the interest sensitivity GAP
method of analysis presented in the following table.  For example, although
certain assets and liabilities may have similar repricing characteristics, they
may react in different degrees to changes in market interest rates.  Also, the
interest rates on certain types of assets and liabilities may fluctuate in
advance of changes in market interest rates, while interest rates on other
types may lag behind changes in market rates.

        The following table sets forth the dollar amount of interest sensitive
assets and interest sensitive liabilities at December 31, 1995, and the
difference between them for the maturity or repricing periods indicated.

        Investment Activities.  The Bank has adopted, as required, Statement of
Financial Accounting Standards ("SFAS") No. 115 "Accounting for Certain
Investments in Debt and Equity Securities."  This Statement requires investment
securities to be segregated as trading securities, held-to-maturity or
available-for-sale based upon management's intent as to the ultimate
disposition of each security acquired.  Investments classified as
held-to-maturity are accounted for at amortized cost, but an institution must
have both the positive intent and the ability to hold those securities to
maturity.  There are very limited circumstances under which securities in the
held-to-maturity category can be sold without jeopardizing the cost basis of
accounting for the remainder of the securities in this category.  Unrealized
gains and losses on available-for-sale securities are excluded from earnings
and reported, net of federal income taxes, as a separate component of
stockholders' equity.

        The Bank's investment policy is approved by its Board.  It has been the
policy of the Bank to maintain relatively high levels of liquidity to meet loan
funding and deposit outflow requirements.  The following table sets forth the
investment securities portfolio of the Bank.

RECENT EVENTS

        There were no material changes in the statement of income for the three
months ended March 31, 1996.  Net income for the first three months in 1996 was
$300,675 or $2.13 per share.  The loan portfolio increased to $65,351,518 from
$61,410,516 at December 31, 1995.  Total deposits were $77,178,590 at March 31,
1996, compared to $70,673,109 at year-end.  Total assets were $86,696,720
compared to $78,927,446 at December 31, 1995.  This growth during the first
quarter of 1996 represents the normal cycle of increased loan demand for real
estate construction purposes.

        Executive Supplemental Income Plan.  The Bank has a nonqualified
Executive Supplemental Income Plan covering 6 officers.  The plan provides
benefits payable upon death, disability or retirement.  Such benefits are
payable monthly over a fifteen year term.

        Employee Stock Ownership Plan.  VB has an Employee Stock Ownership Plan
with 401(k) features ("KSOP") which covers substantially all employees.  The
Plan is a deferred compensation plan in which Bank contributions are used to
provide participating employees with stock in VB.  Employees may choose to
contribute a percentage of their monthly salary on a pre-tax basis to the Plan,
subject to certain limitations.  The Bank currently makes discretionary
matching contributions, subject to a vesting schedule based on length of
service.  In 1995, the Bank contributed $36,502 to the Employee Stock Ownership
Plan.  As of March 31, 1996, the KSOP held 4,602 shares of VB common stock.

        1989 Stock Option Plan.  VB also has a 1989 Stock Option Plan for

options as defined by Section 422A of the Internal Revenue Code, as amended.
Incentive stock options are exercisable at not less than 100% of the fair
market value of the stock at the time of the grant.  The plan also provides for
grants of non-qualified options at the discretion of the administrators of the
plan.  There are 18,522 shares of Company stock reserved for possible issuance

DIRECTOR COMPENSATION

        Directors receive a fee, based on meetings attended during the year,
for serving on the Board of VB or the Bank.  Currently, directors receive
$500.00 per month and $125.00 per special committee meeting.  Directors also
receive incentive compensation based on the return on assets of the Bank.



                                     - 53 -
<PAGE>   65
During 1995, incentive pay was $2,250 per director.  During 1992, each director
then serving was awarded an option to purchase 1,877 shares at an exercise
price of $30.51 per share for 10 years.  The newest member of the VB Board
received an option for 1,877 shares at $40.76 per share after he was elected to
the VB Board in 1995.

CERTAIN TRANSACTIONS AND RELATIONSHIPS

        None of the directors or executive officers of the Bank have or have
had any material interest in any transactions to which the Bank was or is a
party, outside of the ordinary course of the Bank's business, except as set
forth below.

        Certain directors and officers of the Bank, and the companies with
which they are associated, have had and are expected to continue to have
banking transactions with the Bank from time to time in the ordinary course of
business.  Any loans and commitments to lend included in such transactions have
been and will continue to be made in accordance with all applicable laws and
regulations and on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
other persons of similar credit worthiness.

        From time to time the Bank enters into loan participation agreements
with other institutions and individuals in order to facilitate loans which
otherwise would exceed the Bank's legal lending limits.  Pursuant to such an
agreement, the Bank is currently participating in a commercial loan with a
current balance of $1,055,035 to PPI, owned by Mr. Pomajevich, the Chairman of
the Board of the Bank.  The Bank's portion of the outstanding balance is
$196,197.  Robert V. Hyde, a director of the Bank, is participating as a
co-lender of this loan.  Mr. Hyde's portion of the outstanding balance is
$260,475.  Mr. Hyde is also participating as a co-lender of a loan to VB by
Security State Bank of Central Washington.  The loan amount is $1,350,000, of
which Mr. Hyde's portion is $225,000.  This loan will be paid off by WCB on the
Effective Date.  Amounts paid to Mr. Hyde are not considered compensation for
services to the Bank.  In addition, Mr. Hyde is a participating co-lender in
two loans to nonaffiliates of the Bank with an aggregate outstanding balance of
approximately $303,000.

        The Bank does not consider such a loan participation to constitute a
sale of assets for regulatory purposes, and believes the terms of the loan, and
of the agreement, are substantially the same as those prevailing in other
similar loans and participation agreements at the time this loan was made, and
at the time the participation agreement was executed.  The Bank believes that
the loan and the participation agreement are in all respects fair to the Bank.

COMMITTEES OF THE BOARD OF DIRECTORS

        VB has no separate audit or compensation committees.  The entire VB
Board (with the exception of Mr. Stenseth) handles those responsibilities.

                           SUPERVISION AND REGULATION

        The following generally refers to certain statutes and regulations
affecting the banking industry.  These references provide brief summaries only
and are not intended to be complete.  These references are qualified in their
entirety by the referenced statutes and regulations.  In addition, some
statutes and regulations which apply to and regulate the operation of the
banking industry might exist which are not referenced below.  Changes in
applicable statutes and regulations may have a material effect on the business
of WCB, VB and their respective subsidiaries.

                                   WCB AND VB

GENERAL

        As bank holding companies, WCB and VB are subject to the Bank Holding
Company Act of 1956 ("BHCA"), as amended, which places them under the
supervision of the Board of Governors of the Federal Reserve System ("FRB").
In general, the BHCA limits the business of bank holding companies to owning or
controlling banks and engaging in other activities related to banking.  Certain
recent legislation designed to expand interstate branching and relax federal
restrictions on interstate banking will continue to be phased in over the next
two years and may expand opportunities for bank holding companies (for
additional information see below under the heading "WCB's Subsidiary Banks --
Interstate Banking and Branching").  However, the full impact of this
legislation on WCB and VB is unclear at this time.

HOLDING COMPANY STRUCTURE

        FRB Regulation.  A bank holding company must obtain the approval of the
FRB: (1) before acquiring direct or indirect ownership or control of any voting
shares of any bank if, after such acquisition, it would own or control,
directly or indirectly, more than 5% of the voting shares of such bank; (2)
before merging or consolidating with another bank holding company; and (3)
before acquiring substantially all of the assets of any additional banks.

        WCB and VB file annual and certain interim reports as may be required
from time to time by the FRB.  In addition, the FRB performs periodic
examinations of WCB and VB.

        Holding Company Control of Nonbanks.  With certain exceptions, the BHCA
prohibits bank holding companies from acquiring direct or indirect ownership or
control of voting shares in any company which is not a bank or a bank holding
company unless the FRB determines that the activities of such company are so
closely related to banking or managing or controlling banks as to be a proper
incident thereto.  In making such determinations, the FRB considers whether the
performance of such activities by a bank holding company would offer advantages
to the public that would outweigh possible adverse effects.  For example, the
FRB has by regulation determined activities such as, among others, operating an
industrial loan company, industrial bank, savings association, mortgage
company, finance company, trust company, credit card company or factoring
company, performing certain data processing operations, leasing personal or
real property, subject to certain exceptions, and providing investment and
financial advice, are so closely related to banking as to be a proper incident
thereto within the meaning of the BHCA.  On the other hand, activities such as
real estate brokerage and syndication, land development,



                                     - 56 -
<PAGE>   68
property management, underwriting of life insurance not related to credit
transactions, and with certain exceptions, securities underwriting and equity
funding, are not so closely related to banking as to be a proper incident
thereto within the meaning of the BHCA.  In the future, the FRB may from time
to time add to or delete from the list of activities permissible for bank
holding companies.

        Transactions With Affiliates.  WCB and its subsidiary banks, and
likewise VB and the Bank, are deemed affiliates within the meaning of the
Federal Reserve Act and transactions between affiliates are subject to certain
restrictions.  Covered transactions include, subject to specific exceptions,
loans by bank subsidiaries to affiliates, investments by bank subsidiaries in
securities issued by an affiliate, the taking of such securities as collateral,
and the purchase of assets by a bank subsidiary from an affiliate.  When the
Merger is consummated, WCB and its subsidiary banks will be deemed affiliates
within the meaning of the Federal Reserve Act.

        Support of Bank Subsidiaries.  Under FRB policy, a bank holding company
is expected to act as a source of financial and managerial strength to, and
commit resources to support, each of its subsidiary banks.  Any capital loans a
bank holding company makes to its subsidiary banks are subordinate to deposits
and to certain other indebtedness of those subsidiary banks.  The Crime Control
Act of 1990 provides that, in the event of a bank holding company's bankruptcy,
the bankruptcy trustee will assume any commitment the bank holding company has
made to a federal bank regulatory agency to maintain the capital of a
subsidiary bank and this obligation will be entitled to a priority of payment.

        Tie-In Arrangements.  WCB, VB and the bank subsidiaries are prohibited
from engaging in certain tie-in arrangements in connection with any extension
of credit, sale or lease of property or furnishing of services.  For example,
with certain exceptions, neither WCB, VB nor the bank subsidiaries may
condition an extension of credit to a customer on either (1) a requirement that
the customer obtain additional services provided by it or (2) an agreement by
the customer to refrain from obtaining other services from a competitor.

        State Law Restrictions.  As an Oregon corporation, WCB is subject to
certain limitations and restrictions under applicable Oregon corporate law.
Similarly, as a Washington corporation, VB is subject to certain limitations
and restrictions under applicable Washington corporate law.  For example, state
law restrictions in both Oregon and Washington include limitations and
restrictions relating to: indemnification of directors, distributions to
shareholders, transactions involving directors, officers or interested
shareholders, maintenance of books, records, and minutes, and observance of
certain corporate formalities.

        Securities Registration and Reporting.  The common stock of WCB is
registered as a class with the SEC under the Exchange Act and thus is subject
to the periodic reporting and proxy solicitation requirements and the
insider-trading restrictions of that Act.  The periodic reports, proxy
statements, and other information filed by WCB under that Act can be inspected
and copied at or obtained from the Washington, D.C., office of the SEC.  In
addition, the securities issued by WCB are subject to the registration
requirements of the Securities Act of 1933 and applicable state securities laws
unless exemptions are available.

CONTROL TRANSACTIONS

        The Change in Bank Control Act of 1978, as amended, prohibits a person
or group of persons from acquiring "control" of a bank holding company unless
the FRB has been given 60 days' prior written notice of the proposed
acquisition, and within that time period, the FRB has not issued a notice
disapproving the proposed acquisition or extending for up to another 30 days
the period during which such a disapproval may be issued.  An acquisition may
be made before the expiration of the disapproval



                                     - 57 -
<PAGE>   69
period if the FRB issues written notice of its intent not to disapprove the
action.  Under a rebuttable presumption established by the FRB, the acquisition
of 10% or more of a class of voting stock of a bank holding company with a
class of securities registered under Section 12 of the Exchange Act would,
under the circumstances set forth in the presumption, constitute the
acquisition of control.

        In addition, any company would be required to obtain the approval of
the FRB under the BHCA before acquiring 25% (5% if the company is a bank
holding company) or more of the outstanding shares of WCB or VB, or to
otherwise obtain control over the WCB or VB.

                             THE BANK SUBSIDIARIES

GENERAL

        Despite some recent legislative initiatives to reduce regulatory
burdens, banking remains a highly regulated industry.  Legislation enacted from
time to time may increase the cost of doing business, limit or expand
permissible activities, or affect the competitive balance between banks and
other financial and nonfinancial institutions.  Proposals to change the laws
and regulations governing the operations and taxation of banks and other
financial institutions are frequently made in Congress, in state legislatures,
and before various bank regulatory agencies.  In addition, there continue to be
proposals in Congress to restructure the banking system.

        Some of the significant areas of bank regulation, including significant
federal legislation affecting state-chartered banks, are generally discussed
below.

REGULATION OF STATE BANKS

        Oregon state banks, such as WCB's bank subsidiaries, are subject to
primary regulation and examination by the Oregon Department of Consumer and
Business Services ("Oregon Department").  As a Washington State bank, the Bank
is subject to primary regulation and examination by the Washington Director.
WCB's bank subsidiaries are also subject to supervision, examination, and
regulation by certain federal banking agencies, including, in the case of
Valley Commercial Bank (which is a Federal Reserve member bank), the FRB.  The
deposits of each of WCB's bank subsidiaries are insured (to applicable limits)
by, and therefore are subject to regulation by, the FDIC.

        Applicable federal and state statutes and regulations governing a
bank's operations relate, among other matters, to capital requirements,
required reserves against deposits, investments, loans, legal lending limits,
certain interest rates payable, mergers and consolidations, borrowings,
issuance of securities, payment of dividends (see below), establishment of
branches, and dealings with affiliated persons.  The FDIC has authority to
prohibit banks under their supervision from engaging in what they consider to
be an unsafe and unsound practice in conducting their business.  Depository
institutions, such as the bank subsidiaries, are affected significantly by the
actions of the FRB as it attempts to control the money supply and credit
availability in order to influence the economy.

        Washington state banking law provides that the amount of funds which a
bank may lend to a single borrower is generally limited to 20% of capital and
surplus.  For this purpose, capital includes (i) the amount of common stock
outstanding and unimpaired, (ii) the amount of preferred stock outstanding and
unimpaired, and (iii) capital notes or debentures issued pursuant to RCW 30.36.
Surplus includes capital surplus, reflecting the amounts paid in excess of the
par or stated value of capital stock, or amounts contributed to the bank other
than for capital stock, and undivided profits.



                                     - 58 -
<PAGE>   70
DIVIDENDS

        Dividends paid to WCB by its bank subsidiaries are a material source of
WCB's cash flow.  Likewise, dividends paid to VB by the Bank are a material
source of VB's cash flow.  Various federal and state statutory provisions limit
the amount of dividends the bank subsidiaries are permitted to pay to WCB and
VB, respectively,  without regulatory approval.  FRB policy further limits the
circumstances under which bank holding companies may declare dividends.  For
example, a bank holding company should not continue its existing rate of cash
dividends on its common stock unless its net income is sufficient to fully fund
each dividend and its prospective rate of earnings retention appears consistent
with its capital needs, asset quality, and overall financial condition.

        If, in the opinion of the applicable federal banking agency, a
depository institution under its jurisdiction is engaged in or is about to
engage in an unsafe or unsound practice (which, depending on the financial
condition of the institution, could include the payment of dividends), the
agency may require, after notice and hearing, that such institution cease and
desist from such practice.  In addition, the FRB and the FDIC have issued
policy statements which provide that insured banks and bank holding companies
should generally pay dividends only out of current operating earnings.

        Oregon law imposes the following limitations on the payment of
dividends by Oregon state banks: (1) no dividends may be paid that would impair
capital; (2) until the surplus fund of a bank is equal to 50% of its paid-in
capital, no dividends may be declared unless at least 20% of the bank's net
profits for the dividend period have been carried to the surplus account; (3)
dividends cannot be greater than net undivided profits then on hand minus
losses, certain bad debts, certain charged-off assets or depreciation and
accrued expenses, interest, and taxes; and (4) if the surplus fund does not
exceed 50% of paid-in capital at the time of a reduction in the surplus due to
losses, dividends cannot be declared or paid in excess of 50% of net earnings
until the surplus fund is restored to at least the amount from which the
surplus was originally reduced.

        Under these restrictions, as of December 31, 1995, WCB's bank
subsidiaries could have declared dividends of approximately $10.7 million in
the aggregate, without obtaining prior regulatory approval.  The payment of
dividends by banks may also be affected by other factors, such as capital
maintenance requirements.

        Washington statutes prohibit a bank from paying any dividends in an
amount greater than the bank's retained earnings, without approval of the
Washington Director.  The Washington Director has authority to require a bank
to suspend payment of all dividends until the bank has complied with any
requirements made by the Washington Director.

REGULATION OF MANAGEMENT

        Federal law: (1) sets forth circumstances under which officers or
directors of a bank may be removed by the institution's federal supervisory
agency; (2) places restraints on lending by a bank to its executive officers,
directors, principal shareholders, and their related interests; and (3)
prohibits management personnel of a bank from serving as a director or in other
management positions of another financial institution whose assets exceed a
specified amount or which has an office within a specified geographic area.

CONTROL OF FINANCIAL INSTITUTIONS

        No person may acquire "control" of a bank unless the appropriate
federal agency has been given 60 days prior written notice and within that time
the agency has not disapproved the acquisition.



                                     - 59 -
<PAGE>   71
Substantial monetary penalties may be imposed for violation of the change in
control or other provisions of banking laws.  Washington banking laws further
require that 30 days before the acquisition of control, defined as direct or
indirect ownership, control or power to vote 25% or more of the outstanding
stock of a bank, the acquiring party must file with the Washington Director an
application containing certain specified information.  Acquisitions of control
in violation of the statute are deemed void.

FIRREA

        The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") became effective on August 9, 1989.  Among other things, this
far-reaching legislation (1) phased in significant increases in the FDIC
insurance premiums paid by commercial banks; (2) created two deposit insurance
pools within the FDIC, one to insure commercial bank and savings bank deposits
and the other to insure savings association deposits; (3) for the first time,
permitted bank holding companies to acquire healthy savings associations; (4)
permitted commercial banks that meet certain housing-related asset requirements
to secure advances and other federal services from their local Federal Home
Loan Banks; and (5) greatly enhanced the regulators' enforcement powers by
removing procedural barriers and sharply increasing the civil and criminal
penalties for violating statutes and regulations.

FDICIA

        The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") was enacted into law in late 1991.  As required by FDICIA, numerous
regulations have been adopted by federal bank regulatory agencies, including
the following: (1) federal bank regulatory authorities have established five
different capital levels for banks and, as a general matter, enable banks with
higher capital levels to engage in a broader range of activities; (2) the FRB
has issued regulations requiring standardized disclosures with respect to
interest paid on deposits; (3) the FDIC has imposed restrictions on the
acceptance of brokered deposits by weaker banks; (4) the FDIC has implemented
risk-based deposit insurance premiums; and (5) the FDIC has issued regulations
requiring state-chartered banks to comply with certain restrictions with
respect to equity investments and activities in which the banks act as a
principal.

        FDICIA recapitalized the Bank Insurance Fund ("BIF") and required the
FDIC to maintain the BIF and Savings Association Insurance Fund ("SAIF") at
1.25% of insured deposits by increasing deposit insurance premiums as necessary
to maintain such ratio.  FDICIA also required federal bank regulatory
authorities to prescribe, by December 1, 1993, (1) non-capital standards of
safety and soundness; (2) operational and managerial standards for banks; (3)
asset and earnings standards for banks and bank holding companies addressing
such areas as classified assets, capital, and stock price; and (4) standards
for compensation of executive officers and directors of banks.  However, this
provision was modified by recent legislation to allow federal regulatory
agencies to implement these standards through either guidelines or regulations.

INTERSTATE BANKING AND BRANCHING

        The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
(the "Interstate Act") will, over the next two years, permit nationwide
interstate banking and branching under certain circumstances.  This legislation
generally authorizes interstate branching and relaxes federal law restrictions
on interstate banking.  Individual states have the authority to "opt out" of
certain of these provisions.  The Interstate Act currently allows states to
enact "opting-in" legislation that (i) permits interstate mergers within their
own borders before June 1, 1997, and (ii) permits out-of-state banks to
establish de novo branches within the state.  As of September 29, 1995, bank
holding companies may purchase banks in any state, and states may not prohibit
such purchases.  Additionally, beginning June



                                     - 60 -
<PAGE>   72
1, 1997, banks will be permitted to merge with banks in other states as long as
the home state of neither merging bank has opted out.  The Interstate Act
requires regulators to consult with community organizations before permitting
an interstate institution to close a branch in a low-income area.

        Oregon, effective as of February 27, 1995, and Washington, effective
June 6, 1996, have each enacted "opting in" legislation generally permitting
interstate mergers, subject to certain restrictions.  Given that Oregon and
Washington have permitted interstate banking for a number of years, this
legislation is not expected to have a profound impact on banking in Oregon or
Washington or on WCB, VB or the bank subsidiaries' operations in particular.
Nevertheless, the impact that the Interstate Act might have on WCB, VB and the
bank subsidiaries is impossible to predict with accuracy.

CAPITAL ADEQUACY REQUIREMENTS

        The FRB, the FDIC, and the OCC (collectively, the "Federal Banking
Agencies") have established uniform capital requirements for all commercial
banks.  Bank holding companies are also subject to certain minimum capital
requirements.  A bank that does not achieve and maintain required capital
levels may be subject to supervisory action through the issuance of a capital
directive to ensure the maintenance of adequate capital levels.  In addition,
banks are required to meet certain guidelines concerning the maintenance of an
adequate allowance for loan and lease losses.

        The Federal Banking Agencies' "risk-based" capital guidelines establish
a systematic, analytical framework that makes regulatory capital requirements
more sensitive to differences in risk profiles among banking organizations,
takes off-balance sheet exposures into explicit account in assessing capital
adequacy, and minimizes disincentives to holding liquid, low-risk assets.  The
risk-based ratio is determined by allocating assets and specified off-balance
sheet commitments into several categories, with high levels of capital being
required for the categories perceived as representing greater risk.  The risk
weights assigned to assets and credit equivalent amounts of off-balance sheet
items are based primarily on credit risk.  Other types of exposure, such as
interest rate, liquidity and funding risks, as well as asset quality problems,
are not factored into the risk-based ratio.  Such risks, however, will be taken
into account in determining a final assessment of an organization's capital
adequacy.  Under these new regulations, banks were required to achieve a
minimum total risk-based capital ratio of 8% and a minimum Tier 1 risk-based
capital ratio of 4%.

        The Federal Banking Agencies also have adopted leverage ratio standards
that require commercial banks to maintain a minimum ratio of core capital to
total assets (the "Leverage Ratio") of 3%.  Any institution operating at or
near this level is expected to have well-diversified risk, including no undue
interest rate risk exposure, excellent asset quality, high liquidity and good
earnings, and in general, to be a strong banking organization without any
supervisory, financial or operational weaknesses or deficiencies.  Any
institutions experiencing or anticipating significant growth would be expected
to maintain capital ratios, including tangible capital positions, well above
the minimum levels (e.g., an additional cushion of at least 100 to 200 basis
points, depending upon the particular circumstances and risk profile).

        Regulations adopted by the Federal Banking Agencies as required by
FDICIA impose even more stringent capital requirements.  The regulators require
the OCC and other Federal Banking Agencies to take certain "prompt corrective
action" when a bank fails to meet certain capital requirements.  The
regulations establish and define five capital levels at which an institution is
deemed to be "well-capitalized," "adequately capitalized," "undercapitalized,"
"significantly undercapitalized" or "critically undercapitalized." In order to
be "well-capitalized," an institution must maintain, at least 10% total
risk-based capital, 6% Tier 1 risk-based capital, and a 5% Leverage Ratio.
Increasingly severe restrictions are imposed on the payment of dividends and
management fees, asset growth and other aspects of the



                                     - 61 -
<PAGE>   73
operations of institutions that fall below the category of "adequately
capitalized" (which requires at least 8% total risk-based capital, 4% Tier 1
risk-based capital, and a 4% Leverage Ratio).  Undercapitalized institutions
are required to develop and implement capital plans acceptable to the
appropriate federal regulatory agency.  Such plans must require that any
company that controls the undercapitalized institution must provide certain
guarantees that the institution will comply with the plan until it is
adequately capitalized.  As of December 31, 1995, the bank subsidiaries were
not subject to any regulatory order, agreement, or directive to meet and
maintain a specific capital level for any capital measure.

        The Oregon Department has authority under Oregon law to require
shareholders of an Oregon state bank to contribute additional capital to the
bank if its capital becomes impaired.  The capital of a bank is deemed to be
impaired under Oregon law if the value of the bank's assets is insufficient to
pay its liabilities (excluding any liability on outstanding capital debentures)
plus the amount of its paid-in capital.

        The minimum ratio of total capital to risk-adjusted assets (including
certain off-balance sheet items, such as stand-by letters of credit) required
by the FRB for bank holding companies is 8%.  At least one-half of the total
capital must be Tier 1 capital; the remainder may consist of Tier 2 capital.
Bank holding companies are also subject to minimum Leverage Ratio guidelines.
These guidelines provide for a minimum Leverage Ratio of 3% for bank holding
companies meeting certain specified criteria, including achievement of the
highest supervisory rating.  All other bank holding companies are required to
maintain a Leverage Ratio which is at least 100 to 200 basis points higher (4%
to 5%).  These guidelines provide that banking organizations experiencing
internal growth or making acquisitions are expected to maintain strong capital
positions substantially above the minimum supervisory levels, without
significant reliance on intangible assets.

        In August of 1995, the Federal Banking Agencies adopted a final rule
implementing the portion of Section 305 of FDICIA that requires the banking
agencies to revise their risk-based capital standards to ensure that those
standards take adequate account of interest rate risk.  Effective September 1,
1995, when evaluating the capital adequacy of a bank, the Federal Banking
Agencies' examiners will consider exposure to declines in the economic value of
the bank's capital due to changes in interest rates.  A bank may be required to
hold additional capital for interest rate risk if it has a significant exposure
or a weak interest rate risk management process.  Concurrent with the
publication of this final rule, the Federal Banking Agencies proposed for
comment a joint policy statement describing the process the Federal Banking
Agencies will use to measure and assess a bank's interest rate risk.  As
indicated by both the final rule and the joint policy statement,  the Federal
Banking Agencies intend, through a future proposed rule, to incorporate
explicit minimum requirements for interest rate risk into their risk- based
capital standards.  Although the Federal Banking Agencies have indicated that
they anticipate any proposed capital requirement would be based on the
measurement framework described in the joint policy statement, neither the
likelihood that the Federal Banking Agencies will in fact propose such a rule,
the actual requirements or standards established by any such rule nor the
impact the Federal Banking Agency activities discussed above may have on the
bank subsidiaries can be predicted with accuracy at this time.

FDIC INSURANCE

        Generally, customer deposit accounts in banks are insured by the FDIC
for up to a maximum amount of $100,000.  The FDIC has adopted a risk-based
insurance assessment system.  Under this system, depository institutions, such
as the bank subsidiaries, with BIF-insured deposits, are required to pay an
assessment to the BIF ranging from $.0 to $.27 per $100 of deposits based on
the institution's risk classification.  This assessment range is significantly
higher for depository institutions with SAIF-insured

deposits.  Banks at the zero assessment rate will pay the statutory minimum of
$2,000 for deposit insurance.

        The risk classification is based on an assignment of the institution by
the FDIC to one of three capital groups and to one of three supervisory
subgroups.  The capital groups are "well capitalized," "adequately
capitalized," and "undercapitalized."  The three supervisory subgroups are
Group "A" (for financially sound institutions with only a few minor
weaknesses), Group "B" (for those institutions with weaknesses which, if
uncorrected, could cause substantial deterioration of the institution and
increase risk to the deposit insurance fund), and Group "C" (for those
institutions with a substantial probability of loss to the fund absent
effective corrective action).  All the bank subsidiaries are currently deemed
well capitalized and all in Group "A", qualifying for the lowest assessment
classification, presently set at zero.

                   COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF
                            VB AND WCB COMMON STOCK

        The Oregon Business Corporations Act ("OBCA"), as amended,  and WCB's
Articles of Incorporation and Bylaws, both as amended, govern the rights of WCB
shareholders and will govern the rights of VB shareholders who become
shareholders of WCB through the Merger.  The rights of VB shareholders are
currently governed by the Washington Business Corporations Act ("WBCA"), as
amended, and by VB's Articles of Incorporation and Bylaws.  The following is a
brief summary of certain differences between the rights of VB shareholders and
WCB shareholders' rights.  This summary does not purport to be complete and is
qualified by the documents and statutes referenced and by other applicable law.

GENERAL

        Under its Articles of Incorporation, WCB's authorized capital stock
consists of 15,000,000 common stock shares, no par value, and 10,000,000
preferred stock shares, no par value.

        VB's authorized capital stock consists of 10,000,000 common stock
shares with a $1 per share par value and 1,000,000 preferred stock shares with
a $1 per share par value.

        The following is a more detailed description of WCB's and VB's capital
stock.

PREFERRED STOCK

        As of April 18, 1996, neither WCB nor VB had any shares of preferred
stock issued.  The WCB Board is authorized, without further shareholder action,
to issue preferred stock shares with such designations, preferences and rights
as the WCB Board may determine.  Likewise, the VB Board is authorized, without
further shareholder action, to issue preferred stock shares with such
designations, preferences and rights as the VB Board may determine.

COMMON STOCK

        As of April 18, 1996, there were 4,807,679 shares of WCB Common Stock
issued and outstanding, in addition to options for the purchase of 343,431
shares of WCB Common Stock under WCB's employee and director stock option
plans.

        As of April 18, 1996, there were 141,461 shares of VB Common Stock
issued and outstanding, in addition to options for the purchase of 31,523
shares of VB Common Stock under VB's employee and director stock option plans.

DIVIDEND RIGHTS

        Dividends may be paid on WCB Common Stock as and when declared by the
WCB Board out of funds legally available for the payment of dividends.  The WCB
Board may issue preferred stock that is entitled to such dividend rights as the
WCB Board may determine, including priority over the common stock in the
payment of dividends.  The ability of WCB to pay dividends basically depends on
the amount of dividends paid to it by its subsidiaries.  Accordingly, the
dividend restrictions imposed on the subsidiaries by statute or regulation
effectively may limit the amount of dividends WCB can pay (See "SUPERVISION AND
REGULATION -- The Bank Subsidiaries; Dividend Restrictions").  Under the OBCA,
the WCB Board is barred from making any dividend payment if, after giving
effect to such payment, WCB is either unable to pay its debts as they become
due in the usual course of business or WCB's total assets would be less than
the sum of its total liabilities, as more fully provided in ORS 60.181.

        Dividends may be paid on VB Common Stock as and when declared by the VB
Board out of funds legally available for the payment of dividends.  The VB
Board may issue preferred stock that is entitled to such dividend rights as the
VB Board may determine, including priority over the common stock in the payment
of dividends.  The ability of VB to pay dividends basically depends on the
amount of dividends paid to it by its subsidiary.  Accordingly, the dividend
restrictions imposed on its subsidiary by statute or regulation effectively may
limit the amount of dividends VB can pay (See "SUPERVISION AND REGULATION --
The Bank Subsidiaries; Dividend Restrictions").  Under the WBCA, the VB Board
is barred from making any dividend payment if, after giving effect to such
payment, VB is either unable to pay its debts as they become due in the usual
course of business or WCB's total assets would be less than the sum of its
total liabilities, as more fully provided in RCW 23B.06.400.

VOTING RIGHTS

        All voting rights are currently vested in the holders of WCB Common
Stock and VB Common Stock, respectively, each share being entitled to one vote.

        Both WCB's and VB's Articles of Incorporation provide that shareholders
do not have cumulative voting rights in the election of directors.  The WCB
Board and the VB Board are each authorized to determine the voting rights of
any preferred stock that may be issued.

PREEMPTIVE RIGHTS

        Neither the holders of WCB Common Stock nor the holders of VB Common
Stock have preemptive rights to subscribe to any additional securities that may
be issued.

LIQUIDATION RIGHTS

        If WCB is liquidated, the holders of WCB Common Stock are entitled to
share, on a pro rata basis, WCB's remaining assets after provision for
liabilities.  The WCB Board is authorized to determine the liquidation rights
of any preferred stock that may be issued, including priority over the
liquidation rights of holders of WCB Common Stock.

        Similarly, VB Common Stock holders are entitled to share, pro rata,
VB's remaining assets after provision for liabilities, if VB is liquidated.
The VB Board is authorized to determine the liquidation rights of any preferred
stock that may be issued, including priority over the liquidation rights of
holders of VB Common Stock.

ASSESSMENTS

        All outstanding shares of VB Common Stock and of WCB Common Stock are
fully paid and nonassessable.

BOARD OF DIRECTORS

        WCB's Articles of Incorporation provide for division of its Board into
three classes, as nearly equal in number as possible.  Each director serves for
a three-year term, and the classes are staggered so that one class is elected
each year.  The WCB Board must consist of at least eight (8), but no more than
twenty (20) directors; the WCB Board sets the exact number by resolution.
Currently, the WCB Board has thirteen (13) directors.  A WCB director may not
be removed without cause before his or her term expires, unless two-thirds of
the shareholders entitled to vote on the matter, vote in favor of removal.

        VB's Bylaws provide that each member of its Board serves for a one-year
term (or until the next annual shareholders' meeting and until the director's
successor is elected and qualified).  The VB Board must consist of at least
five (5), but no more than fifteen (15) directors; the VB Board sets the exact
number by resolution.  Currently, the VB Board has seven (7) directors.  VB's
shareholders, by an affirmative majority vote, may remove any director from
office, with or without cause, before his or her term expires.

INDEMNIFICATION AND LIMITATION OF LIABILITY

        WCB's Articles of Incorporation provide for indemnification, to the
fullest extent permissible under the OBCA, of its directors against all
expense, liability, and loss (including attorneys' fees) incurred by him or her
by reason of or arising from the fact that he or she is or was a director of
WCB or is or was serving at WCB's request as a director, officer, partner,
trustee, employee, or agent of another foreign or domestic corporation,
partnership, joint venture, trust, employee benefit plan, or other enterprise,
and these indemnification rights continue as to a person who has ceased to be a
director, officer , partner, trustee, employee, or agent and inure to the
benefit of his or her heirs, executors, and administrators.  WCB's Articles of
Incorporation authorize WCB, through its Bylaws, and the WCB Board to provide
indemnification to WCB's officers, employees, and agents, to the extent
permitted by law.  WCB's Bylaws provide that WCB will indemnify its directors
and officers to the full extent permitted by the OBCA.  However, WCB will not
provide indemnification when (a) a director or officer commits intentional
misconduct or knowingly violates the law; (b) a director or officer is adjudged
liable to WCB in a proceeding by or in the right of WCB; or (c) a director or
officer is adjudged liable in any proceeding charging improper personal benefit
on the basis that the director or officer improperly received a personal
benefit.  Indemnification rights and procedures, including entitlements to
advanced expenses, are set forth in more detail in WCB's Bylaws.

        VB's Articles of Incorporation provide that a director is not
personally liable to VB or VB's shareholders for monetary damages for conduct
as a director, except for (a) intentional misconduct or knowing violations of
law; (b) conduct violating RCW 23B.08.310 (unlawful distributions); or (c)
transactions from which the director will personally receive a benefit in
money, property or services to which the director is not legally entitled.
VB's Articles of Incorporation provide for indemnification of directors and
officers under certain circumstances.  The VB Board may authorize
indemnification of VB's other employees and agents in accordance with VB's
Articles of Incorporation.  Indemnification rights and procedures, including
entitlements to advanced expenses, are set forth in more detail in VB's
Articles of Incorporation.

AMENDMENT OF ARTICLES OF INCORPORATION AND BYLAWS

        Under Oregon law, WCB's shareholders may amend WCB's Articles of
Incorporation by an affirmative majority vote of the shares entitled to vote on
the matter.  The WCB Board may make the amendments listed in ORS 60.434 to the
Articles of Incorporation without shareholder approval.  Either the
shareholders or, subject to certain restrictions, the WCB Board may amend WCB's
Bylaws.

        Unless the corporation's Articles of Incorporation provide otherwise,
the WBCA requires approval of two-thirds of the shareholders entitled to vote
on the matter in order to amend the corporation's articles.  VB's Articles
allow VB's shareholders to amend VB's Articles by an affirmative majority vote
of the shares entitled to vote on the matter.  The VB Board may make the
amendments listed in RCW 23B.10.020 to the Articles of Incorporation without
shareholder approval.  Either the shareholders or the VB Board may amend VB's
Bylaws.

REPURCHASE OF SHARES

        Under Oregon and Washington law, a corporation may acquire shares of
its own stock.  Therefore, both WCB and VB may, under applicable state law,
repurchase shares of their own capital stock.

DISSENTERS' RIGHTS

        Under the WBCA, a shareholder is entitled to dissent from, and, upon
perfection of the shareholder's appraisal right, to obtain the fair value of
his or her shares in the event of certain corporate actions, including certain
mergers, share exchanges, sales of substantially all assets of the corporation,
and certain amendments to the corporation's articles of incorporation that
materially and adversely affect shareholder rights.

        Similar dissenters' rights are generally provided to shareholders under
the OBCA.  However, under the OBCA, dissenters' rights are not available to
shareholders of any class or series if the shares of that class or series were
registered on a national securities exchange or quoted on the National
Association of Securities Dealers, Inc. Automated Quotation System as a
National Market System issue on the record date for the shareholders' meeting
at which the corporate action ordinarily entitling the shareholders to
dissenters' rights was taken or on the date a copy or summary of the plan of
merger is mailed to shareholders under ORS 60.491.

SALES OF ASSETS, MERGERS AND DISSOLUTIONS - VOTING

        Under the WBCA, unless the articles of incorporation provide for a
lesser vote (but not less than a majority), approval by at least two-thirds of
the outstanding shares entitled to vote or two-thirds of each voting group is
required for mergers, assets sales, and dissolutions.  Separate voting by
voting groups is required (i) on a plan of share exchange and (ii) on a plan of
merger if it contains provisions that would require separate voting if
contained in an amendment to articles of incorporation.  VB's Articles of
Incorporation reduce the VB shareholder vote otherwise required under the WBCA
for mergers, asset sales, and dissolutions to a simple majority of all votes
entitled to be cast by each voting group.  The OBCA requires approval by the
holders of a majority of the shareholders entitled to vote on the matter for
assets sales, mergers and dissolutions.  Both the OBCA and the WBCA contain
provisions setting forth certain circumstances under which no vote by the
shareholders of a corporation surviving a merger is required.

POTENTIAL "ANTI-TAKEOVER" PROVISIONS

        WCB's Articles of Incorporation and Oregon and Washington statutes
contain certain provisions which may limit or prevent certain acquisitions.
These provisions are briefly summarized below.

        1.       WCB's Articles of Incorporation.

        WCB's Articles of Incorporation include certain provisions that could
make more difficult the acquisition of WCB by means of a tender offer, a proxy
contest, merger or otherwise.  These provisions include (1) restrictions on
removal of directors which could limit changes in the composition of the WCB
Board (See "Board of Directors," above); (2) certain nonmonetary factors that
the WCB Board may consider when evaluating a takeover offer (discussed in more
detail below); and (3) a requirement that at least two-thirds of the
shareholders approve a Change in Control of WCB or a sale of substantially all
of WCB's assets, unless the transaction is approved by 75% of the WCB Board.

        In addition, the authorization of preferred stock, which is intended
primarily as a financing tool and not as a defense against takeovers, may
potentially be used by management to make more difficult uninvited attempts to
acquire control of WCB (e.g., by diluting the ownership interest of a
substantial shareholder, increasing the amount of consideration necessary for a
shareholder to obtain control, or selling authorized but unissued shares to
friendly third parties).

        WCB's Articles of Incorporation allow the WCB Board to consider
nonmonetary factors in evaluating another party's offer to (a) make a tender or
exchange for any equity security of WCB, (b) merge or consolidate WCB with
another corporation or association, or (c) purchase or otherwise acquire all or
substantially all of WCB's assets.  Specifically, the Articles allow the WCB
Board, in determining what is in the best interests of WCB and its
shareholders, to consider all relevant factors, including the effects on its
employees, customers, suppliers, and other constituents of WCB and its
subsidiaries and on the communities in which WCB and its subsidiaries are
located.

        The staggered terms for WCB's directors, provisions in WCB's Articles
of Incorporation permitting the removal of directors only for cause except by a
super-majority shareholder vote, requirement of a super-majority vote of
shareholders to approve change-in-control transactions unless such transactions
receive a super-majority approval of the WCB Board, permitting the
consideration of nonmonetary factors in evaluating takeover proposals, the
availability of WCB's preferred stock for issuance without shareholder
approval, and the WCB Board's ability to expand the Board size and fill
resulting vacancies, may have the effect of lengthening the time required for a
person to acquire control of WCB through a tender offer, proxy contest, the
election of a majority of the WCB Board, or otherwise, and may deter any
potential unfriendly offers or other efforts to obtain control of WCB.  This
could deprive WCB's shareholders of opportunities to realize a premium for
their WCB Common Stock and could make removal of incumbent directors more
difficult, even in circumstances where such action was favored by a majority of
WCB's shareholders.

        2.       Oregon Law.

        Oregon's significant anti-takeover provisions are generally described
below.

        ORS 60.357(5), a statutory provision similar to the provision described
above in WCB's Articles of Incorporation, allows directors to consider
nonmonetary factors when evaluating a takeover offer.

        ORS 60.157 allows a corporation's board of directors to impose certain
restrictions or conditions on rights, options or warrants issued by the
corporation for the purchase of shares, without violating the



                                     - 67 -
<PAGE>   79
general rule (see ORS 60.131) that all shares within the same class must have
identical preferences, limitations, and relative rights.  With respect to any
person (or such person's transferee) owning or offering to acquire a specified
number or percentage of the outstanding stock or other securities of the
corporation, this statute allows the board to (a) preclude or limit such
person's exercise, transfer, or receipt of rights, options or warrants and (b)
invalidate or void the rights, options or warrants held by such person.  This
permits the adoption of a Shareholder Rights Plan or a so called "Poison Pill."

        The Oregon Control Share Act (ORS 60.801, et.seq.) ("OCSA") operates to
deny voting rights to potential acquirors of a corporation who trigger the OCSA
by purchasing enough shares to cross certain thresholds designated in the
statute.  Under the OCSA, the shares of an "acquiring person" obtained in a
"control share acquisition" are denied voting rights unless (a) the target's
board or shareholders approve the acquisition in advance; (b) a majority of the
disinterested shareholders approve restoration of the acquiring person's voting
rights; (c) the acquiring person sells the shares to an unaffiliated person; or
(d) the corporation, in its Articles of Incorporation or Bylaws, "opts out" of
the control share provisions.  At this time, WCB has not opted-out of the OCSA.
Transactions in which the corporation acquires its own shares and mergers
involving an agreement and plan of merger to which the corporation is a party
are excluded from the definition of "control share acquisition."

        ORS 60.835 prohibits business combinations with interested shareholders
for a period of three years following the date the shareholder becomes
interested, unless an exception applies.  A shareholder becomes interested when
the shareholder acquires 15% or more of the outstanding voting stock of the
corporation.  Business combinations with an interested shareholder are not
prohibited if (a) the board of directors approves in advance either the
business combination or the transaction in which the shareholder becomes an
interested shareholder; (b) the shareholder acquires 85% or more of the
outstanding voting stock in the same transaction in which the shareholder
becomes interested; or (c) the board of directors approves the business
combination and at least two-thirds of the outstanding voting stock (excluding
the interested shares) approve the transaction (by affirmative vote and not by
written consent).  ORS 60.835 does not apply if a shareholder inadvertently
becomes interested and divests as soon as practicable.

        3.       Washington Law.

        Washington's significant anti-takeover provisions are generally
described below.

        RCW 23B.17.020 provides that all shareholders of Washington business
corporations, like VB, are entitled to receive equal consideration for their
shares in certain business combinations.  This statute generally provides that
an interested person exercising control cannot exercise such control in
connection with certain corporate transactions unless the transaction is
approved by the affirmative vote of the holders of two-thirds of the shares
entitled to vote.  Shares owned by interested persons are not entitled to vote
in connection with such business combinations, but are counted for the proposes
of quorum requirements.  An "interested shareholder" is a person, including
affiliates of such person, who beneficially owns 20% or more of the outstanding
shares of a corporation.  The two-thirds vote requirement is not applicable if
(i) a majority of the company's board of directors approves the transaction,
(ii) a majority of the company's board of directors determines that the fair
market value of the consideration to be received by noninterested shareholders
is not less than the highest price paid by any interested shareholder within
two years before the transaction, or (iii) a company's initial or amended
Articles specifically exclude the provision's applicability.

        RCW 23B.17.020 is designed to discourage the two-step, front-end loaded
tender offer.  Typically, that occurs when a person makes a cash tender offer
to a premium above the current market price for a majority of the company's
voting stock, and then follows that purchase with a later business



                                     - 68 -
<PAGE>   80
combination, such as a merger, that "freezes out" the remaining minority
shareholders at a lower price than that paid in the cash tender offer.

        Washington law also requires prior approval by a majority of the board
of directors of the target company in certain acquisition transactions.  RCW
23B.19.040 prohibits corporations that have a class of voting stock registered
with the SEC pursuant to Section 12 of the Securities Exchange Act of 1934 from
engaging in any Significant Business Transactions (including, mergers or
consolidations; certain sales, leases, exchanges, mortgages, pledges,
transfers, or other dispositions or encumbrances of assets; termination of 5%
or more of the corporation's employees; issuances or redemptions of stock;
sales of assets, liquidation, or dissolution of the corporation;
reclassifications of the corporation's securities; and allowing the acquiring
person or an affiliate or associate to receive any disproportionate benefit as
a shareholder) for a period of five years after a person or group acquires 10%
or more of the corporation's outstanding voting stock, unless the acquisition
is approved in advance by majority vote of the board of directors.  The statute
will not apply to a person who "inadvertently" acquires 10% of the shares, if
such person divests itself as soon as practicable of sufficient shares to fall
below the 10% threshold.  Any acquisition that violates this statute is deemed
to be void and the proposed acquiror's certificate of authority to transact
business in Washington is revoked.  As the Common Stock is not currently
registered under Section 12 of the Securities Act, these state law provisions
do not apply.

                             CERTAIN LEGAL MATTERS

        The validity of the WCB Common Stock to be issued in the Merger will be
passed upon for WCB by its counsel, Graham & Dunn, a professional corporation,
Seattle/Tacoma, Washington.  Graham & Dunn, P.C. also will give an opinion
concerning certain tax matters related to the Merger.

                                    EXPERTS

        The consolidated financial statements of WCB as of December 31, 1995,
1994 and 1993, and for each of the three years in the period ended December 31,
1995, incorporated by reference into this Prospectus/Proxy Statement, have been
audited by Arthur Andersen LLP, independent public accountants, as indicated in
their reports with respect thereto, and are included therein in reliance upon
the authority of such firm as experts in giving said reports.

        The financial statements of VB included in this Prospectus/Proxy
Statement and in the Registration Statement have been audited by Moss Adams
LLP, independent certified public accountants, to the extent and for the
periods set forth in their report appearing elsewhere herein, and are included
in reliance upon such report given upon the authority of said firm as experts
in auditing and accounting.

                                 OTHER MATTERS

        The VB Board is not aware of any business to come before the Meeting
other than those matters described above in this Prospectus/Proxy Statement.
However, if any other matters should properly come before the Meeting, it is
intended that proxies in the accompanying form will be voted in respect thereof
in accordance with the judgment of the persons voting the proxies.

                          INDEPENDENT AUDITOR'S REPORT

To the Board of Directors and Stockholders
Vancouver Bancorp

We have audited the accompanying consolidated balance sheets of Vancouver
Bancorp as of December 31, 1995 and 1994, and the related consolidated
statements of income, retained earnings, and cash flows for the years then
ended. These financial statements are the responsibility of Vancouver Bancorp's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Vancouver Bancorp as of
December 31, 1995 and 1994, and the results of their operations and their cash
flows for the years then ended in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           DECEMBER 31, 1995 AND 1994

NOTE 1  -    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         (a) Organization - In March 1994, Vancouver Bancorp (Bancorp) was
established for the purpose of becoming a holding company of Bank of Vancouver
(the Bank) by acquiring 100% of its outstanding common stock. This
reorganization was accomplished by each share of common stock of Bank of
Vancouver being converted and exchanged for a share of Bancorp's common stock.
All intercompany activity has been eliminated in the preparation of these
consolidated financial statements.

         (b) Nature of operations - The Bank is a state chartered institution
authorized to provide banking services by the State of Washington. Bank of
Vancouver began operations on June 27, 1989. The Bank offers commercial banking
services primarily to small and medium-sized businesses, professionals, and
retail customers in Clark County, Washington.

         (c) Management's estimates and assumptions - In preparing the
consolidated financial statements, management is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of the
date of the balance sheet and revenues and expenses for the period. Significant
estimations made by management primarily involve the calculation of the
allowance for loan losses. Actual results could differ significantly from those
estimates.

         (d) Investment securities - Vancouver Bancorp adopted the Financial
Accounting Standards Board's Statement No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," as of January 1, 1994. The
pronouncement requires the Bank to specifically identify its investment
securities as "held-to-maturity," "available-for-sale," or "trading accounts."
Accordingly, management has determined that all investment securities held at
December 31, 1995 and 1994, as either "held-to-maturity" or "available-for-sale"
and conform to the following accounting policies:

             Securities held-to-maturity - Bonds, notes, and debentures for
which the Bank has the intent and ability to hold to maturity are reported at
cost, adjusted for premiums and discounts that are recognized in interest income
using the interest method over the period to maturity.

             Securities available-for-sale - Available-for-sale securities
consist of bonds, notes, debentures, and certain equity securities not
classified as held-to-maturity securities. Unrealized gains and losses, net of
tax, on available-for-sale securities are reported as a net amount in a separate
component of equity until realized. Fair values for investment securities are
based on quoted market prices. Gains and losses on the sale of
available-for-sale securities are determined using the specific-identification
method.

             Declines in the fair value of individual held-to-maturity and
available-for-sale securities below their cost that are other than temporary,
result in write-downs to their fair value. The write-downs would be included in
earnings as realized losses. Premiums and discounts are recognized in interest
income using the effective interest method over the period to maturity.

         (e) Loans net of allowance for loan losses and unearned income - Loans
are stated at the amount of unpaid principal, reduced by an allowance for
estimated losses on loans and unearned income. Interest on loans is calculated
by using the simple-interest method on daily balances of the principal amount
outstanding. The allowance for loan losses is established through a provision
for loan losses charged to expenses. Loans are charged against the allowance for
loan losses when management believes that the collectibility of the principal is
unlikely. The allowance is an amount that management believes is adequate to
absorb possible losses on existing loans that may become uncollectible, based on
evaluations of the collectibility of loans and prior loan loss experience. The
evaluations take into consideration such factors as changes in the nature and
volume of the loan portfolio, overall portfolio quality, review of specific
problem loans, and current economic conditions that may affect the borrower's
ability to pay. Accrual of interest is discontinued on a loan when management
believes, after considering economic and business conditions, collection efforts
and collateral position, that the borrower's financial condition is such that
collection of interest is doubtful. Loan origination fees and certain direct
origination costs are capitalized and recognized by the effective interest
method as an adjustment to the yield of the related loan.

             The Bank adopted the Financial Accounting Standards Board's
Statements No. 114 "Accounting by Creditors for Impairment of a Loan" and No.
118 "Accounting by Creditors for Impairment of a Loan - Income Recognition and
Disclosures" as of January 1, 1995. These pronouncements require that impaired
loans be measured based on the present value of expected future cash flows
discounted at the loan's effective interest rate or at the loan's market price
or the fair value of the collateral if the loan is collateral dependent. The
adoption of these statements did not have a material effect on the consolidated
financial statements.

         (f) Property and equipment - Property and equipment are stated at cost,
less accumulated depreciation, computed principally by the straight-line method
over the estimated useful lives of the assets which range from three to five
years for furniture and equipment and 31-1/2 years for building premises.

         (g) Income taxes - Deferred tax assets and liabilities are reflected at
currently enacted income tax rates applicable to the period in which the
deferred tax assets or liabilities are expected to be realized or settled. As
changes in tax laws or rates are enacted, deferred tax assets and liabilities
are adjusted through the provision for income taxes.

             (Continued)

         (h) Net income per share - Earnings per share were computed by dividing
net income by the weighted average number of shares of common stock and common
stock equivalents outstanding for the years ending December 31, 1995 and 1994.
Common stock equivalents include the number of shares that would have been
purchased with the proceeds from the exercise of the options based on the
average price of common stock during the year.

         (i) Off-balance-sheet financial instruments - In the ordinary course of
business, the Bank has entered into off-balance-sheet financial instruments
consisting of commitments to extend credit as well as commercial letters of
credit and standby letters of credit. Such financial instruments are recorded in
the financial statements when they are funded or related fees are incurred or
received.

             The Financial Accounting Standards Board issued Statement No. 119
"Disclosures about Derivative Financial Instruments and Fair Value of Financial
Instruments" which became effective for the Bank for the year ending December
31, 1995. This pronouncement requires that banks holding derivative financial
instruments, disclose quantitative and qualitative information about the
instruments. As of December 31, 1995, and for the year then ended, the Bank held
no derivative financial instruments.

         (j) Fair value of financial instruments - The following methods and
assumptions were used by the Bank in estimating fair values of financial
instruments as disclosed herein:

             Cash and cash equivalents - The carrying amounts of cash and
short-term instruments approximate their fair value.

             Held-to-maturity and available-for-sale securities - Fair values
for investment securities, excluding restricted equity securities, are based on
quoted market prices. The carrying values of restricted equity securities
approximate fair values.

             Loans receivable - For variable-rate loans that reprice frequently
and have no significant change in credit risk, fair values are based on carrying
values. Fair values for certain mortgage loans (for example, one-to-four family
residential), credit card loans, and other consumer loans are based on quoted
market prices of similar loans sold in conjunction with securitization
transactions, adjusted for differences in loan characteristics. Fair values for
commercial real estate and commercial loans are estimated using discounted cash
flow analyses, using interest rates currently being offered for loans with
similar terms to borrowers of similar credit quality. Fair values for impaired
loans are estimated using discounted cash flow analyses or underlying collateral
values, where applicable.

<PAGE>   93
NOTE 1  -    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - 
             (Continued)

             Deposit liabilities - The fair values disclosed for demand deposits
are, by definition, equal to the amount payable on demand at the reporting date
(that is, their carrying amounts). The carrying amounts of variable-rate,
fixed-term money market accounts and certificates of deposit (CDs) approximate
their fair values at the reporting date. Fair values for fixed-rate CDs are
estimated using a discounted cash flow calculation that applies interest rates
currently being offered on certificates to a schedule of aggregated expected
monthly maturities on time deposits.

             Short-term borrowings - The carrying amounts of federal funds
purchased, borrowings under repurchase agreements, and other short-term
borrowings maturing within 90 days approximate their fair values. Fair values of
other short-term borrowings are estimated using discounted cash flow analyses
based on the Bank's current borrowing rates for similar types of borrowing
arrangements.

             Long-term debt - The fair values of the Bank's long-term debt are
estimated using discounted cash flow analyses based on the Bank's current
borrowing rates for similar types of borrowing arrangements.

             Accrued interest - The carrying amounts of accrued interest
approximate their fair values.

             Off-balance-sheet instruments - The Bank's off-balance-sheet
instruments include unfunded commitments to extend credit and standby letters of
credit. The fair value of these instruments is not considered practicable to
estimate because of the lack of quoted market prices and the inability to
estimate fair value without incurring excessive costs.

         (k) Statement of cash flows - Cash equivalents are generally short-term
investments with a maturity of three months or less. Cash and cash equivalents
normally include cash on hand and amounts due from banks.

         (l) Reclassifications - Certain reclassifications have been made to the
1994 financial statements to conform with current year presentations.

             During 1995, pursuant to implementation guidance on accounting for
certain investments in debt and equity securities issued in a Special Report by
the Financial Accounting Standards Board, the Bank reassessed the
appropriateness of its classifications for investment securities. Accordingly,
securities with an amortized cost of $1,526,194 were transferred from the
held-to-maturity category to the available-for-sale category. This resulted in
the recognition of an unrealized gain on available-for-sale securities, net of
tax, of approximately $34,300 at the time of transfer.

             As of December 31, 1995 and 1994, investment securities with a book
value of $1,832,443 and $1,450,802, respectively, have been pledged to secure
public deposits and for other purposes required or permitted by law.

             Impaired loans of $268,129 at December 31, 1995, have been
recognized in conformity with FASB Statement No. 114 as amended by FASB
Statement No. 118. The investment in impaired loans at December 31, 1995, was
$218,684. The total allowance for loan losses related to these loans was $49,445
on December 31, 1995. Interest income on impaired loans of $20,285 was
recognized for cash payments received in 1995. Had the impaired loans performed
according to their original terms, additional interest income of $18,657 would
have been recognized during 1995.

             While these estimates of fair value are based on management's
judgment of the most appropriate factors, there is no assurance that were the
Bank or Bancorp to have disposed of such items at December 31, 1995, the
estimated fair values would necessarily have been achieved at that date, since
market values may differ depending on various circumstances. The estimated fair
values at December 31, 1995, should not necessarily be considered to apply at
subsequent dates.

             In addition, other assets and liabilities of the Bank and Bancorp
that are not defined as financial instruments are not included in the above
disclosures, such as property and equipment. Also, nonfinancial instruments
typically not recognized in the financial statements nevertheless may have value
but are not included in the above disclosures. These include among other items,
the estimated earnings power of core deposit accounts, the earnings potential of
loan servicing rights, customer goodwill, and similar items.

NOTE 10  -   TRANSACTIONS WITH RELATED PARTIES

             Certain directors, executive officers, and principal stockholders
are customers of and have had banking transactions with the Bank, and the Bank
expects to have such transactions in the future. All loans and commitments
included in such transactions were made in compliance with applicable laws on
substantially the same terms (including interest rates and collateral) as those
prevailing at the time for comparable transactions with other persons and do not
involve more than the normal risk of collectibility or present any other
unfavorable features. The amount of loans outstanding to directors, executive
officers, principal stockholders, and companies with which they are associated
was as follows:

NOTE 11  -   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

             In the normal course of business to meet the financing needs of its
customers, the Bank is a party to financial instruments with off-balance-sheet
risk. These financial instruments include commitments to extend credit and the
issuance of letters of credit. These instruments involve, to varying degrees,
elements of credit and interest rate risk in excess of the amount recognized in
the statement of financial position. The contract amounts of those instruments
reflect the extent of involvement the Bank has in particular classes of
financial instruments.

NOTE 11  -   FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK - (Continued)

             The Bank's exposure to credit loss in the event of nonperformance
by the other party to the financial instrument for commitments to extend credit
and letters of credit written is represented by the contractual amount of those
instruments. The Bank uses the same credit policies in making commitments and
conditional obligations as it does for on-balance-sheet instruments. Unless
noted otherwise, the Bank does not require collateral or other security to
support financial instruments with credit risk.

</TABLE>

             Commitments to extend credit are agreements to lend to a customer
as long as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. The amount of collateral obtained, if deemed
necessary by the Bank upon extension of credit, is based on management's credit
evaluation of the counterparty. Collateral held varies but may include accounts
receivable, inventory, property, plant and equipment, and income-producing
properties.

             Letters of credit are conditional commitments issued by the Bank to
guarantee the performance of a customer to a third-party. Those guarantees are
primarily issued to support public and private borrowing arrangements, including
commercial paper, bond financing, and similar transactions. The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loan facilities to customers.

NOTE 12 -    CONCENTRATIONS OF CREDIT RISK

             All of the Bank's loans, commitments, commercial letters of credit,
and standby letters of credit have been granted to customers in the Bank's
market area. The majority of such customers are also depositors of the Bank.
Investments in state and municipal securities involve governmental entities
within the Bank's geographical region. The concentrations of credit by type of
loan are set forth in Note 3. The distribution of commitments to extend credit
approximates the distribution of loans outstanding. Commercial and standby
letters of credit were granted primarily to commercial borrowers as of December
31, 1995. The Bank's loan policy does not allow the extension of credit to any
single borrower or group of related borrowers in excess of $300,000 without
approval from the Board of Director's loan committee.

         (b) Legal contingencies - In the ordinary course of business, the Bank
may become involved in litigation arising from normal bank activities. In the
opinion of management and legal counsel, the ultimate disposition of these
actions will not have a material adverse effect on the Bank's financial position
or results of operations.

NOTE 14 -    CREDIT ARRANGEMENTS AND NOTE PAYABLE

             The Bank is a member of the Federal Home Loan Bank (FHLB) of
Seattle. As a member, the Bank has a committed line of credit up to 10% of total
assets. During 1994, the collateral arrangement was changed from physical
possession to a blanket pledge agreement. Borrowings generally provide for
interest at the then current published rates. The Bank had no borrowings
outstanding from the FHLB at December 31, 1995 or 1994.

NOTE 15 -    STOCK OPTION PLANS

             The Board of Directors and Stockholders adopted an Employee Stock
Option Plan (the "Plan") in June 1989 for the benefit of the Bank's and
Bancorp's key employees. Under the Plan, which offers both incentive and
nonqualified stock options, the maximum number of shares which may be optioned
and sold is 18,552 shares of Bancorp's outstanding common stock, subject to
adjustment for changes in the Bank's capitalization. Options granted under the
Plan are exercisable at any time by the grantee up to the 10th anniversary of
the date of the grant. The option price for the shares of common stock to be
issued under the Plan is established by the Board of Directors or its committee,
but, in the case of incentive stock options, will be no less than the fair
market value of the stock on the date of grant.

             In October 1989, the Bank entered into incentive and nonqualified
stock option agreements with its President, pursuant to the Plan. Under the
incentive stock option agreement, the President was given options to purchase
4,000 shares of the Bank's common stock at $25 per share for a 10-year period
from the date of grant. Under the nonqualified stock option agreement, the
President was given options to purchase up to 5,914 shares of common stock for
$22 per share also for a 10-year period. As of December 31, 1995, the President
had exercised no options to acquire Bank or Bancorp stock.

             In December 1992, an Incentive Stock Option and Nonstatutory Stock
Option Plan was approved and adopted. This Plan provides nonstatutory stock
options for both directors and employees as well as incentive stock options for
employees of Bancorp. The maximum number of shares optioned and sold under this
Plan is 30,000, subject to adjustment for changes in Bancorp's capitalization.
Options granted under the Plan will be evidenced by Stock Option Agreements
stipulating terms and conditions under which the options have been granted. All
options under the Plan are exercisable by the grantees up to the 10th
anniversary of the date of grant. However, incentive stock options do not become
exercisable for a period of one year after the date of grant. In no event will
the shares granted under either the nonstatutory or incentive.

options, be exercisable at prices less than 100% of the fair market value of the
stock at the time of grant.

             In February 1993, the President and certain officers were granted
incentive stock options to acquire 5,342 shares of common stock at a price of
$30.51 per share. Simultaneously, nonstatutory stock options for 11,262 shares
of common stock at $30.51 per share were granted to directors of the Bank. In
December 1993, other officers were granted incentive options to acquire 3,128
shares of common stock at a price of $35.10. In June 1995, nonstatutory options
to acquire 1,877 shares of common stock at a price of $40.76 were granted to a
Director.

             In 1995, nonstatutory stock options for 1,877 shares were exercised
by a Bank director and resulted in the recognition of $57,261 of additional
capital.

             The following table summarizes options granted and exercisable as
of December 31, 1995:

NOTE 16 -    EMPLOYEE BENEFIT PLANS

             Effective January 1, 1992, the Bank adopted a Salary Savings Plan
which allowed employees to defer certain amounts of compensation for income tax
purposes under Section 401(k) of the Internal Revenue Code. The Plan was amended
and incorporated into an Employee Stock Ownership Plan (KSOP) on November 18,
1992. The KSOP is a deferred compensation plan in which Bank contributions are
used to provide participating employees with stock in the Bank and in which
employee contributions are made on a before-tax basis pursuant to provisions
under Internal Revenue Code Section 401(k). Essentially all full-time employees
over the age of 21 and meeting length of service requirements are eligible to
participate in the Plan.

Employees may elect to contribute and defer, within statutory limits, up to 15%
of their annual compensation into the Plan. Their contributions and those of the
Bank will be invested by Plan Trustees into either an equity or general
investment fund. The equity fund will focus on the

NOTE 16 -    EMPLOYEE BENEFIT PLANS - (Continued)

acquisition of the Bancorp's common stock. The general investment fund will be a
diversified portfolio.

             Employer contributions to the Plan are all discretionary and
consist of basic, optional, and matching allocations. Employee contributions are
fully vested at all times. Basic and optional contributions are primarily
invested in Bancorp stock and fully vested when participating employees have six
or more years of service. Matching contributions relate to employee salary
reduction elections and contributions to the Plan. Matching contributions also
vest when participating employees have six or more years of service. For the
years ended December 31, 1995 and 1994, the Bank contributed cash of $36,502 and
$24,571, respectively, into the KSOP.

             During 1992, the Bank also adopted and implemented an Executive
Supplemental Income (ESI) Plan. The Plan was established to provide retirement
benefits for officers key to the Bank's growth and profitability. The Plan,
which covers certain executive officers, is being indirectly funded through the
purchase of corporate owned life insurance. The accumulated asset value of
acquired insurance policies will serve to pay future retirement benefits of
covered executives. However, these future retirement benefits are earned through
the working lifetime of covered executives and, once fully vested, are only
equal to the excess of the cash value of the corporate life insurance policy
over premiums paid by the Bank. As of December 31, 1995, the cash value of the
policies approximated the total premiums paid and, therefore, no employee
benefit obligation has been accrued.

             As of December 31, 1995 and 1994, the cash surrender value of the
corporate owned life insurance policies was $616,192 and $448,740, respectively.

NOTE 19 -    SUBSEQUENT EVENT

             On February 15, 1996, Bancorp entered into a definitive agreement
to merge with West Coast Bancorp (WCB). The agreement provides that, upon
consummation of the merger, stockholders of Bancorp will receive WCB stock worth
$11.6 million. Based upon the terms of the merger agreement, the exchange ratio
is subject to the average price of WCB stock over a ten-day period prior to the
closing of the merger. While it is anticipated that the merger will be completed
in mid-1996, the acquisition is subject to certain conditions, including the
approval of Bancorp's shareholders. If completed, it is expected the merger will
be accounted for using the pooling of interests method. Transactions accounted
for as a pooling of interests reflect the assets, liabilities, stockholders'
equities, and results of operations of the separate entities as though the
entities had been combined as of the earliest date reported.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         WCB's Articles of Incorporation provide for indemnification, to the
fullest extent permissible under the OBCA, of its directors against all expense,
liability, and loss (including attorneys' fees incurred by him or her by reason
of or arising from the fact that he or she is or was a director of WCB or is or
was serving at WCB's request as a director, officer, partner, trustee, employee,
or agent of another foreign or domestic corporation, partnership, joint venture,
trust, employee benefit plan, or other enterprise, and these indemnification
rights continue as to a person who has ceased to be a director, officer ,
partner, trustee, employee, or agent and inure to the benefit of his or her
heirs, executors, and administrators. WCB's Articles of Incorporation authorize
WCB, through its Bylaws, and the WCB Board to provide indemnification to WCB's
officers, employees, and agents, to the extent permitted by law. WCB's Bylaws
provide that WCB will indemnify its directors and officers to the full extent
permitted by the OBCA. However, WCB will not provide indemnification when (a) a
director or officer commits intentional misconduct or knowingly violates the
law; (b) a director or officer is adjudged liable to WCB in a proceeding by or
in the right of WCB; or (c) a director or officer is adjudged liable in any
proceeding charging improper personal benefit on the basis that the director or
officer improperly received a personal benefit. Indemnification rights and
procedures, including entitlements to advanced expenses, are set forth in more
detail in WCB's Bylaws.

ITEM 22.  UNDERTAKINGS

         (a) The undersigned registrant hereby undertakes:

             (1) To file, during any period in which it offers or sells
securities, a post-effective amendment to this registration statement to;

                 (i)   Include any prospectus required by Section 10(a)(3) of 
the Securities Act;

                 (ii)  Reflect in the prospectus any facts or events which,
individually or together, represent a fundamental change in the information in
the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation
from the low or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b)
if, in the aggregate, the changes in volume and price represent no more than a
20 percent change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
and

                 (iii) Include any additional or changed information on the plan

<PAGE>   109
             (2) For determining liability under the Securities Act, to treat
each such post-effective amendment as a new registration statement of the
securities offered, and the offering of the securities at that time shall be
deemed to be the initial bona fide offering.

             (3) To file a post-effective amendment to remove from registration
any of the securities that remain unsold at the end of the offering.

         (b) To advise all directors and officers that insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.

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

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

                PLAN AND AGREEMENT OF REORGANIZATION AND MERGER
                                    BETWEEN
                WEST COAST BANCORP, HB ACQUISITION CORPORATION,
                                      AND
                               VANCOUVER BANCORP

dated as of February 15, 1996, is between WEST COAST BANCORP ("WCB"), an Oregon

VANCOUVER BANCORP ("VB"), a Washington corporation.

                                    PREAMBLE

         The management of WCB and VB believe that the merger of VB with and
into HB, on the terms and conditions set forth in this Agreement, is in the best
interests of the stockholders of WCB and VB.

         under Oregon law and is a registered bank holding company under the
         Bank Holding Company Act of 1956, as amended ("BHCA").  WCB's principal
         offices are located in Lake Oswego, Oregon.  WCB owns all of the

         Commercial Bank, Valley Commercial Bank and West Coast Mortgage, Inc.
         HB is a corporation duly organized and validly existing under
         Washington law.  HB's principal offices are located in Seattle,
         Washington.  VB is a corporation duly organized and validly existing
         under Washington law and is a registered bank holding company under the
         BHCA.  VB's principal offices are located in Vancouver, Washington.  VB
         owns all of the outstanding shares of common stock of the Bank of
         Vancouver ("Bank").

B.       THE MERGER.  At the Effective Date, the following will occur:

         1.       VB will merge with and into HB ("Merger") and HB will be the
                  surviving corporation under the name HB ("Combined
                  Corporation").

         2.       Except as otherwise provided in this Agreement, the
                  outstanding shares of VB Common Stock will be converted into
                  the right to receive shares of WCB Common Stock.

C.       BOARD APPROVALS.  The respective boards of directors of WCB, HB, and VB
         have approved this Agreement and authorized its execution and delivery.

<PAGE>   125
D.       OTHER APPROVALS.  The Merger is subject to:

         1.       satisfaction of the conditions described in this Agreement;

         2.       approval by the shareholders of VB;

         3.       approval by WCB as the sole shareholder of HB; and

         4.       approval or acquiescence, as appropriate, by (i) the Board of
                  Governors of the Federal Reserve System ("Federal Reserve
                  Board") and (ii) the Director of the Washington Department of
                  Financial Institutions (collectively, "Regulatory Approvals").

E.       EMPLOYMENT AGREEMENT.  WCB has entered into an employment agreement
         with  Lee S. Stenseth, President and Chief Executive Officer of the
         Bank,  which will take effect on the Effective Date.

F.       DIRECTOR NONCOMPETITION AGREEMENT.  Each Director of VB and the Bank's
         board of directors has signed a Director Noncompetition Agreement.
         These noncompetition agreements will take effect on the Effective Date.

G.       STOCK OPTION AGREEMENT.  As an inducement to and condition of WCB's
         execution of this Agreement, VB has approved the grant of an option to
         WCB under the Stock Option Agreement, as provided in Subsection 1.8.

H.       INTENTION OF THE PARTIES. The parties intend the Merger to qualify, for
         accounting purposes, as a "pooling of interests." The parties intend
         the Merger to qualify, for federal income tax purposes, as a tax-free
         reorganization under Section 368 of the Internal Revenue Code of 1986,
         as amended ("IRC").

                                   AGREEMENT

         In consideration of the mutual promises set forth in this Agreement,
WCB, HB, and VB agree as follows:

                                   SECTION 1.
                              TERMS OF TRANSACTION

         1.1. TRANSACTION. Subject to the terms and conditions set forth in this
         Agreement and in the other documents referred to in this Agreement, VB
         will merge with and into HB in the Merger. The term "Transaction" means
         the Merger transaction contemplated by this Agreement, subject to any
         modifications WCB elects in accordance with Subsection 1.5.

         1.2. MERGER. On the Effective Date, VB will merge with and into HB,
         with HB being the surviving corporation ("Combined Corporation"), in
         accordance with the provisions of, and with

                                      -2-
<PAGE>   126
         the effect provided in RCW Title 23B. On the Effective Date, the
         articles of incorporation and bylaws of the Combined Corporation will
         be the articles of incorporation and bylaws of HB in effect immediately
         before the Effective Date. On the Effective Date, the directors and
         officers of HB will become the directors and officers of the Combined
         Corporation. On the Effective Date, HB's shares then issued and
         outstanding will become issued and outstanding shares of the Combined
         Corporation. The Combined Corporation's name will be HB, and VB's
         principal office before the Merger will be the Combined Corporation's
         principal office.

                  1.2.1. CLOSING OF THE MERGER. Closing of the Transaction will
                  take place in accordance with Section 2 ("Closing"). Except
                  for Dissenting Shares, all shares of VB Common Stock issued
                  and outstanding immediately before Closing will be converted
                  into the right to receive the consideration described in
                  Subsection 1.3 at Closing, by virtue of the Merger and under
                  RCW 23B, without any action on the holder's part.

                  1.2.2. THE BANK. By virtue of the Merger, the Bank will become
                  the Combined Corporation's wholly owned subsidiary. On the
                  Effective Date, the Bank's board of directors will be all
                  directors who are the Bank's directors immediately before the
                  Merger plus one additional WCB director designated by WCB.
                  These directors will serve on the Bank's board of directors
                  until the next annual meeting of the Bank's shareholders or
                  until their successors have been elected and qualified. At the
                  1997 annual meeting of the Bank's shareholders, the directors
                  then serving on the Bank's board of directors may propose a
                  slate of directors for election to the Bank's board. WCB, as
                  the Bank's sole shareholder, will elect these proposed
                  directors to serve on the Bank's board of directors until the
                  1998 annual meeting of the Bank's shareholders, but WCB may
                  refuse to elect any of these proposed directors if WCB has
                  good cause to do so. Nothing in this Subsection 1.2.2 or this
                  Agreement restricts in any way any rights of the Bank's
                  shareholders and directors at any time after the Effective
                  Date to nominate, elect, select, or remove the Bank's
                  directors.

         1.3.     CONSIDERATION.

                  1.3.1. AMOUNT OF CONSIDERATION. Except as otherwise provided
                  in Subsection 1.4, the aggregate consideration ("Purchase
                  Price") VB's stockholders will be entitled to receive from WCB
                  in connection with the Transaction will be WCB Common Stock
                  with an aggregate value equal to $11,581,000, as calculated in
                  accordance with Subsection 1.3.2.

                                      -3-
<PAGE>   127
                  1.3.2. FORM OF CONSIDERATION. Subject to the terms, conditions
                  and limitations set forth in this Agreement, holders of VB
                  Common Stock will be entitled to exchange their VB Common
                  Stock shares for WCB Common Stock shares, upon surrender of
                  the holder's certificate or certificates in accordance with
                  Subsection 1.3.8. Each holder, in exchange for each share of
                  VB Common Stock the stockholder holds of record on the
                  Effective Date, will be entitled to receive that number of
                  shares of WCB Stock calculated by dividing the Purchase Price
                  by the Average Closing Price (or the Modified Average Closing
                  Price in the circumstances specified in Subsection 7.2.5), and
                  by further dividing the number so reached by the aggregate
                  number of shares of VB Common Stock that on the Effective Date
                  are either (i) issued and outstanding or (ii) subject to
                  unexercised options. The shares of WCB Common Stock to be
                  issued to VB Shareholders under this Agreement in connection
                  with the Transaction are referred to as the "WCB Shares."

                  1.3.3. AVERAGE CLOSING PRICE. For the purpose of this
                  Agreement, the "Average Closing Price" means the average
                  (rounded to the nearest penny) of each Daily Sales Price of
                  WCB stock for the ten consecutive trading days ending on and
                  including the fifth trading day preceding the Effective Date.
                  But, if this average is less than $15.30, the Average Closing
                  Price will be $15.30, and if this average is more than $18.70,
                  the Average Closing Price will be $18.70. All prices per share
                  under this Subsection 1.3.3 will be appropriately adjusted to
                  account for stock dividends, split-ups, mergers, combinations,
                  conversions, share exchanges or the like.

                  1.3.4. DAILY SALES PRICE. For the purposes of this Agreement,
                  "Daily Sales Price" means for any trading day, the arithmetic
                  average (unrounded) of the closing bid and asked prices of WCB
                  stock in the over-the-counter market as such prices are
                  reported by the automated quotation system of the National
                  Association of Securities Dealers, Inc., or in the absence of
                  this source, by any other source that WCB and VB mutually
                  agree on.

                  1.3.5. NO FRACTIONAL SHARES. WCB will not issue fractional
                  shares of WCB Common Stock. In lieu of fractional shares of
                  WCB Common Stock, if any, each shareholder of VB who is
                  otherwise entitled to receive a fractional share of WCB Common
                  Stock will receive an amount of cash equal to the product of
                  such fraction times the Average Closing Price. Such fractional
                  share interest will not include the right to vote or receive
                  dividends or any interest on dividends.

                  1.3.6. EFFECT ON HB SHARES. HB's Common Stock shares issued
                  and outstanding immediately before the Effective Date will
                  remain outstanding and unchanged after the

                                      -4-
<PAGE>   128
                  Transaction. After the Transaction, these shares will
                  constitute all of the issued and outstanding shares of the
                  capital stock of the Combined Corporation.

                  1.3.7. OPTIONS. For purposes of this Agreement, the term "VB
                  Options" means options issued by VB or the Bank in accordance
                  with its employee and director stock option plans. Each holder
                  of these VB Options will be entitled to receive, in exchange
                  for all of his VB Options, options to purchase that number of
                  WCB Common Stock shares to which such holder would have been
                  entitled under Subsection 1.3.2 if such holder had exercised
                  such VB Options immediately before Closing. All such options
                  will be subject to the same terms as the VB Options exchanged
                  in accordance with this Subsection 1.3.7.

                  1.3.8.            CERTIFICATES.

                           (a)      Surrender of Certificates.  Each certificate
                                    evidencing VB Common Stock (other than
                                    Dissenting Shares) will, on and after the
                                    Effective Date, be deemed for all corporate
                                    purposes to represent and evidence only the
                                    right to receive WCB Common Stock or cash in
                                    accordance with the provisions of this
                                    Subsection 1.3, until the VB stockholder
                                    surrenders the certificate to an agent
                                    designated by WCB and VB to effect the
                                    exchange of VB Common Stock for WCB Common
                                    Stock or cash ("Exchange Agent"), together
                                    with a properly completed and executed form
                                    of transmittal letter.  Until any such
                                    certificate evidencing VB Common Stock is so
                                    surrendered, the holder of such VB Common
                                    Stock will not have any right to receive any
                                    certificates evidencing WCB Common Stock or
                                    cash in lieu of fractional shares.

                           (b)      Issuance of Certificates in Other Names.  If
                                    any certificate evidencing WCB Common Stock
                                    is to be issued in a name other than that in
                                    which the certificate(s) for VB Common Stock
                                    surrendered in exchange is registered, the
                                    person requesting this exchange must first:
                                    (1) establish the right to receive the
                                    certificate evidencing WCB Common Stock and
                                    (2) either pay to the Exchange Agent any
                                    transfer or other taxes required by reason
                                    of the issuance of such certificate in a
                                    name other than the registered holder of the
                                    certificate surrendered or establish to the
                                    satisfaction of the Exchange Agent that such
                                    tax has been paid or is not applicable.

                                    If the Exchange Agent receives: (1)
                                    satisfactory evidence of VB Common Stock
                                    ownership represented by a missing
                                    certificate and (2) any indemnification
                                    assurances that the Exchange Agent may
                                    require from persons claiming such
                                    ownership, the Exchange Agent will be
                                    authorized to issue WCB Common Stock for any
                                    VB Common Stock certificate that has been
                                    lost, stolen or destroyed.

                           (d)      Rights to Dividends and Distributions.
                                    After the Effective Date, no holder of a
                                    certificate evidencing shares of VB Common
                                    Stock will be entitled to receive any
                                    dividends or other distributions otherwise
                                    payable to holders of record of WCB Common
                                    Stock on any date after the Effective Date
                                    unless the holder (1) is entitled to receive
                                    WCB Common Stock and (2) has surrendered his
                                    or her certificates evidencing shares of VB
                                    Common Stock in exchange for WCB Common
                                    Stock.  This surrender of certificates will
                                    not deprive the holder of any dividends or
                                    distributions that the holder is entitled to
                                    receive for a date before this surrender as
                                    a record holder of VB Common Stock.  When
                                    the holder surrenders his or her
                                    certificates, the holder will receive the
                                    amount, without interest, of any cash
                                    dividends and any other distributions
                                    distributed after the Effective Date on the
                                    whole number of shares of WCB Common Stock
                                    the holder's VB Common Stock was converted
                                    into at the Effective Date.

                           (e)      Checks in Other Names. If any check for cash
                                    in lieu of fractional shares is to be issued
                                    in a name other than the name that the VB
                                    Common Stock certificate surrendered in
                                    exchange for cash is registered in, the
                                    person requesting the exchange must
                                    establish the right to receive this cash.

         1.4. PAYMENT TO DISSENTING SHAREHOLDERS. For purposes of this
         Agreement, "Dissenting Shares" means those shares of VB Common Stock as
         to which shareholders have perfected their dissenters' rights under RCW
         23B.11.070(2)(b) and RCW 23B.13. Each outstanding dissenting share of
         VB Common Stock will be converted at Closing into the rights provided
         under RCW 23B.11.070(2)(b) and RCW 23B.13.

         1.5. ALTERNATIVE STRUCTURES. Subject to the conditions set forth below,
         WCB may, within 60 days of the execution of this Agreement and in its
         sole discretion, elect to consummate the Transaction by means other
         than those specified in this

                                      -6-
<PAGE>   130
         Section 1. If WCB so elects, any means, procedures or amendments
         necessary or desirable to consummate the Transaction, in the opinion of
         WCB's counsel, will supersede any conflicting, undesirable or
         unnecessary provisions of this Agreement; but, unless this Agreement is
         amended in accordance with Section 9, the following conditions will
         apply: (1) the type and amount of consideration set forth in Subsection
         1.3 will not be modified and (2) the tax consequences to VB and its
         shareholders will not be adversely affected. If WCB elects an
         alternative structure under this Subsection 1.5, VB will cooperate with
         and assist WCB with the following: (1) any amendments to this Agreement
         necessary or desirable in the opinion of WCB's counsel and (2) the
         preparation and filing of any applications, documents, instruments and
         notices necessary or desirable, in the opinion of WCB's counsel, to
         obtain the necessary shareholder approvals and approvals of any
         regulatory agency, administrative body or other governmental entity.

         1.6. LETTER OF TRANSMITTAL. WCB will prepare a transmittal letter form
         reasonably acceptable to VB for use by shareholders holding VB Common
         Stock. Certificates representing shares of VB Common Stock must be
         delivered for payment in the manner provided in the transmittal letter
         form. On or about the Effective Date, WCB will mail the transmittal
         letter form to VB shareholders.

         1.7. UNDELIVERED CERTIFICATES.  If outstanding certificates for VB
         Common stock are not surrendered or the payment for them is not claimed
         before such payments would escheat or become the property of any
         governmental unit or agency, the unclaimed items will, to the extent
         permitted by abandoned property or any other applicable law, become the
         property of WCB (and to the extent not in its possession will be paid
         over to WCB), free and clear of all claims or interests of any person
         previously entitled to such items. Notwithstanding the foregoing,
         neither WCB nor any other party to this Agreement will be liable to any
         holder of VB Common Stock for any amount paid to any governmental unit
         or agency having jurisdiction over any such unclaimed items under the
         abandoned property or other applicable law of the jurisdiction, and WCB
         will pay no interest on amounts owed to shareholders for shares of VB
         Common Stock.

         1.8. STOCK OPTION AGREEMENT.  As a condition to the execution of this
         Agreement, WCB and VB will sign a Stock Option Agreement of even date
         with this Agreement.

                                   SECTION 2.
                           CLOSING OF THE TRANSACTION

         2.1. CLOSING. Closing will occur on the Effective Date (or the
         Postponed Effective Date if Subsection 7.2.5.(b) applies). If Closing
         does not occur on or before October 31, 1996 ("Termination Date"),
         either WCB or VB may terminate this

                                      -7-

         Agreement in accordance with Section 7. Unless WCB and VB agree upon
         another date, the Effective Date will be a date selected by WCB and
         within five (5) business days after the following:

                           been either fulfilled or waived; and

                  (b)      each approval required by Section 5 has been granted,
                           and all applicable waiting periods have expired.

         2.2. EVENTS OF CLOSING. On the Effective Date, all properly executed
         documents required by this Agreement will be delivered to the proper
         party, in form consistent with this Agreement. If any party fails to
         deliver a required document on the Effective Date or otherwise defaults
         under this Agreement on or before the Effective Date, then the
         Transaction will not occur unless the adversely affected party waives
         the default.

         2.3. PLACE OF CLOSING.  Unless WCB and VB agree otherwise, the Closing
         will occur at the corporate office of WCB, Lake Oswego, Oregon at 10:00
         a.m. on the Effective Date, or any other time during normal business
         hours WCB and VB may agree on.

                                    "Executive Officers") know of no reason why

                  respective businesses only in the ordinary and usual course of
                  the businesses and (2) no change or development or combination
                  of changes or developments has occurred that, individually or
                  in the aggregate, is reasonably likely to result in a Material
                  Adverse Effect with respect to it or its subsidiaries. For
                  purposes of this Agreement, "Material Adverse Effect" with
                  respect to any corporation means an effect that: (1) is
                  materially adverse to the business, financial condition,
                  results of operations or prospects of the corporation and its
                  subsidiaries taken as a whole; (2) significantly and adversely
                  affects the ability of the corporation to consummate the
                  transactions contemplated by this Agreement by the Termination
                  Date or to perform its material obligations under this
                  Agreement; or (3) enables any persons to prevent the
                  consummation by the Termination Date of the transactions
                  contemplated by this Agreement. No Material Adverse Effect
                  will be deemed to have occurred on the basis of any effect
                  resulting from actions or omissions of the corporation taken
                  with the prior consent of the other parties to this Agreement.

                  3.1.7.            MATERIAL AGREEMENTS.

                                    plan, as of the last day of the most recent
                                    plan year ended before the date of this
                                    Agreement, the actuarially determined
                                    present value of all "benefit liabilities"
                                    within the meaning of ERISA Section
                                    4001(a)(16) (as determined on the basis of
                                    the actuarial assumptions contained in the
                                    Pension Plan's most recent actuarial
                                    valuation), did not exceed the then- current
                                    value of the assets of such Pension Plan,
                                    and to the knowledge of its Executive
                                    Officers, there has been no change in the
                                    financial condition of such Pension Plan
                                    since the last day of the most recent plan

                                    change such conclusion. There would be no

                                    contributed during the preceding 12 months,
                                    if such withdrawal liability were determined
                                    as if a "complete withdrawal," within the
                                    meaning of ERISA Section 4203, had occurred
                                    as of the date of this Agreement.

                                    Statements, neither it nor its subsidiaries
                                    have any obligations for retiree health and
                                    life benefits.

                                    this Agreement, the transactions
                                    contemplated by this Agreement and the Stock

                                    of time or the giving of notice would be
                                    reasonably likely to result in noncompliance
                                    with such Environmental Laws.

                           (c)      To the knowledge of its Executive Officers,

                           (d)      To the knowledge of its Executive Officers:
                                    no storage tanks underground or otherwise
                                    are present on the Subject Property or, if
                                    present, none of such tanks are leaking and
                                    each of them is in full compliance with all
                                    Environmental Laws.  With respect to any
                                    Subject Property, it and its subsidiaries do
                                    not own, possess or control any PCBs, PCB-

                                    emitted, or are threatened to be discharged,
                                    released or emitted, at or on any Subject
                                    Property, except for those types and
                                    quantities of Hazardous Substances typically
                                    used in an office environment and that have
                                    not created conditions requiring remediation
                                    under any Environmental Law.

                           (e)      To the knowledge of its Executive Officers
                                    and except for the investigation or
                                    monitoring by the Environmental Protection
                                    Agency or similar state agencies in the
                                    ordinary course, no part of the Subject
                                    Property has been or is scheduled for
                                    investigation or monitoring under any
                                    Environmental Law.

         3.3.     EXCEPTIONS TO REPRESENTATIONS AND WARRANTIES.

                  3.3.1. DISCLOSURE OF EXCEPTIONS.  Each exception set forth in
                  a Schedule is disclosed only for purposes of the
                  representations and warranties referenced in that exception;
                  but the following conditions apply:

                           (a)      no exception is required to be set forth in
                                    a Schedule if its absence would not result
                                    in the related representation or warranty
                                    being found untrue or incorrect under the
                                    standard established by this Subsection 3.3;
                                    and

                           (b)      the mere inclusion of an exception in a
                                    Schedule is not an admission by a party that
                                    such exception represents a material fact,
                                    event or circumstance or would result in a
                                    Material Adverse Effect with respect to that
                                    party.

                  3.3.2. NATURE OF EXCEPTIONS. No representation or warranty
                  contained in Subsection 3.1 or 3.2 will be found untrue or
                  incorrect and no party to this Agreement will have breached a
                  representation or warranty due to the following: the existence
                  of any fact, circumstance or event if that fact, circumstance
                  or event, individually or taken together with all similar
                  facts, circumstances or events, would not, or, in the case of
                  Subsection 3.2.5, is not reasonably likely to, have a Material
                  Adverse Effect with respect to such party.

                           (a)      VB will make VB's, and cause its

                                    representatives.  These items will be open
                                    for inspection, audit and direct
                                    verification of: (1) loan or deposit

                                    subsidiaries to, cooperate fully in any such
                                    inspection, audit, or direct verification
                                    procedures, and VB will, and will cause its
                                    subsidiaries to, make available all
                                    information reasonably required by or on
                                    behalf of WCB.

                           (b)      At WCB's request, VB will request any third

                                    or Subsequent VB/Bank Financial Statements
                                    to disclose to WCB the work papers or any
                                    similar materials related to these financial
                                    statements.

                  4.1.2.            ORDINARY AND USUAL COURSE.  Without the
                  prior written consent of WCB, VB will, and will cause the Bank
                  to, conduct its business only in the ordinary and usual course

                                    Agreement);

                                    other distribution, either directly or

                                    Transaction, which expenses are estimated
                                    not to exceed $120,000.

                  4.1.3. CONDUCT REGARDING REPRESENTATIONS AND WARRANTIES. VB
                  will not do or cause to be done anything that would cause any
                  representation or warranty in Subsection 3.1 or 3.2 to be
                  untrue or inaccurate if made at Closing, except as otherwise
                  contemplated or required by this Agreement or consented to in
                  writing by WCB.

                  practice.

                  will cause the Bank to, use all reasonable efforts to:

                  or higher.

                  4.1.7. COMPENSATION. VB will not, and will not allow the Bank

                  directors, officers, employees, agents or consultants other
                  than normal increments in compensation in accordance with VB's
                  past practices with respect to the timing and amounts of such
                  increments. Without the prior written approval of WCB, VB will
                  not, and will not allow the Bank to, commit to, execute or
                  deliver any employment agreement with any party not terminable

                                    of VB and the Bank;

                           (b)      will present fairly the financial position
                                    and operating results of VB and the Bank at
                                    the times indicated and for the periods
                                    covered;

                           (d)      will reflect all VB's and the Bank's
                                    liabilities, contingent or otherwise, on the
                                    respective dates and for the respective

                                      -30-
<PAGE>   154
                                    (1) not required to be so reflected in
                                    accordance with GAAP or (2) not significant
                                    in amount.

                  4.1.9. NO SOLICITATION. Neither VB nor any of its officers or
                  directors, directly or indirectly, will solicit, encourage,
                  entertain, or facilitate any other proposals or inquiries for
                  an acquisition of the shares or assets of VB or its
                  subsidiaries or enter into discussions concerning any such
                  acquisition, except as otherwise required by law. No such
                  party will make available to any person not affiliated with VB
                  or WCB any information about its business or organization that
                  is not either routinely made available to the public generally
                  or required by law.

                  4.1.10. TITLE POLICIES. At WCB's request, VB will provide WCB
                  with title reports issued by a title insurance company
                  reasonably satisfactory to WCB, showing unencumbered fee
                  simple title or vendee's interest to all real Property owned
                  by VB or the Bank, other than other real estate owned, and
                  unencumbered leasehold interests in all real Property leased
                  by VB or the Bank, and containing only such exceptions,
                  reservations and encumbrances as may be consented to in
                  writing by WCB or may be consistent with Subsection 3.2.3. For
                  purposes of this Agreement, "Property" includes any property
                  that VB or the Bank has owned or leased, or in which VB or the
                  Bank holds any security interest, mortgage, other lien or
                  interest.

                  4.1.11. REVIEW OF LOANS. VB will, and will cause the Bank to,
                  permit WCB to conduct an examination of the Bank's loans to
                  determine credit quality and the adequacy of the Bank's
                  allowance for loan losses. WCB will have continued access to
                  the Bank's loans through Closing to update the examination. At
                  WCB's reasonable request, VB and the Bank will provide WCB
                  with current reports updating the information set forth in
                  Schedule 7.

         4.2.     REGISTRATION STATEMENT OR FAIRNESS HEARING.  At WCB's sole
                  discretion, the parties will follow either: (1) the procedures
                  listed in Subsection 4.2.1 or (2) the procedures listed in
                  Subsection 4.2.2. WCB will make this election within 60 days
                  after this Agreement is signed. If WCB chooses Subsection
                  4.2.2, WCB may subsequently cancel this choice at any time and
                  elect Subsection 4.2.1 if WCB reasonably and in good faith
                  determines that proceeding under Subsection 4.2.2 and relying
                  on the exemption in Section 3(a)(10) of the Securities Act
                  from registration of the WCB Shares would be materially
                  disadvantageous to WCB, HB or their shareholders or might give
                  rise to legal or regulatory penalties.

                                            Statement.

                                    (3)     Nothing will be included in the

               destruction or loss (whether or not covered by insurance) has
               occurred, and no other event, individually or in the aggregate,
               having or potentially having a Material Adverse Effect with
               respect to VB or the Bank has occurred. VB's certificate referred

                        31, 1995, required by Federal Accounting Standards
                        ("FAS") 115);

                    (b) all of the Bank's deposits, other than: (1) brokered
                        deposits, (2) public funds, and (3) certificates of

                        losses (taking into account any recommendations made by
                        VB's certified public accountants) and (2) at Closing
                        will be not less than 1.5% of the Bank's aggregate loans
                        and leases; and

                    (d) the reserves set aside for the contingent liabilities
                        reflected in the Subsequent VB/Bank Financial Statements
                        will be adequate to absorb all reasonably anticipated
                        losses.

               information revealed during WCB's previous examinations of the

               substance reasonably satisfactory to VB and its counsel, to the
               effect that consummation of the Transaction will not result in a
               taxable event for VB or WCB, and otherwise will have each of the
               effects specified below:

                     (a) The Transaction will qualify as a reorganization within
                         the meaning of IRC Section 368(a)(1)(A).

                     (b) Under IRC Section 354(a)(i), VB's stockholders who, in
                         accordance with Section 1, exchange their VB Common
                         Stock shares solely for WCB Common Stock shares will
                         not recognize gain or loss on the exchange.

                         interest, subject to the

                         the extent that enforcement (but not validity) may be
                         limited by bankruptcy, insolvency, reorganization,
                         moratorium, or similar laws generally affecting the
                         enforcement of the rights of creditors and by generally

                     (a) If the parties proceed under Subsection 4.2.1, the
                         Registration Statement, as it may have been amended,
                         required in connection with the shares of WCB Common
                         Stock to be issued to Shareholders under Subsection 1.3
                         and as described in Subsection 4.2 will have become
                         effective, and no stop order suspending the
                         effectiveness of such Registration Statement will have
                         been issued or will remain in effect, and no
                         proceedings for that purpose will have been initiated
                         or threatened by the SEC the basis for which remains in
                         effect.

                     (b) If the parties proceed under Subsection 4.2.2, the
                         Oregon Director will have issued an order of
                         registration and a finding that the Plan of Exchange is
                         fair, just, and equitable and free from fraud and the
                         WCB Shares will be exempt from registration under the

               dated immediately before VB mails the Prospectus/Proxy Statement
               or Proxy/Disclosure Statement to its shareholders, to the effect
               that the financial terms of the Transaction are financially fair
               to VB's shareholders. WCB will provide VB's investment advisor
               with such information as it may reasonably request in order to

               5.2.19.   ACCOUNTING TREATMENT. It will have been determined to
               the satisfaction of WCB that the Transaction will be treated for
               accounting purposes as a "pooling of interests" in accordance
               with APB Opinion No. 16, and WCB will have received a letter to
               such effect from Arthur Andersen, LLP, certified public
               accountants.

               5.2.20.   SOLICITATION OF EMPLOYEES. Neither any member of VB's

               affiliated will have solicited any employee of VB, WCB or HB with
               the intention of causing such employee to terminate his or her

               earlier date, in which case they will be true in all material
               respects as of that earlier date). These representations and
               warranties will have the same force and effect as if they had
               been made at Closing. WCB and HB will have delivered to VB their
               respective certificates, executed by duly authorized officers of

               destruction or loss (whether or not covered by insurance) has
               occurred, and no other event, individually or in the aggregate,
               having or potentially having a Material Adverse Effect with
               respect to WCB has occurred. WCB's certificate referred to in
               Subsection 5.3.2 will state that the conditions identified in
               this Subsection 5.3.3 are satisfied.

               5.3.4. NO GOVERNMENTAL PROCEEDINGS. No action or proceeding will
               have been commenced or threatened by any governmental agency to
               restrain or prohibit or invalidate the Transaction.

               5.3.6. TAX OPINION. The tax opinion specified in Subsection

                        equitable and free from fraud (if the parties proceed
                        under Subsection 4.2.2).

               5.3.8.   CASH PAID. The aggregate of the cash paid to holders of
               VB Common Stock under this Agreement and applicable law will not

               effective as of Closing, a VB director satisfactory to VB to

               5.3.11.  APPROVAL BY COUNSEL. All actions, proceedings,
               instruments and documents required in connection with this
               Agreement, the Transaction, and all other related legal matters

               5.3.12.  OTHER MATTERS. VB will have received such other 
               opinions, certificates, and documents as VB may reasonably
               request in connection with this Agreement and the Transaction.

                                   SECTION 6.
                        DIRECTORS, OFFICERS AND EMPLOYEES

         6.1.  DIRECTORS. As a condition to the execution of this Agreement, VB
         will cause each member of VB's and the Bank's board of directors to
         enter into a written noncompetition agreement on or before the date
         this Agreement is signed. These noncompetition agreements will take
         effect on the Effective Date.

         6.2.  EMPLOYMENT AGREEMENT. As a condition to the execution of this
         Agreement, Lee S. Stenseth will make himself available to continue as
         President of the Bank, in accordance with the terms and conditions set
         forth in an employment agreement of even date with this Agreement,
         which will take effect on the Effective Date.

         6.3.  DIRECTOR AND EX-OFFICIO MEMBER APPOINTED. On the Effective Date,
         WCB will cause one director, acceptable to WCB, who is a director of VB
         immediately before the Effective Date, to be elected or appointed to
         WCB's board of directors to serve until his successor is elected and
         qualified. As of the Effective Date and until the end of his term as
         President of the Bank, WCB will allow Lee S. Stenseth to attend the

                                      -43-
<PAGE>   167
         meetings of WCB's board of directors as an ex-officio member of WCB's
         board of directors. Nothing in this Subsection 6.3 or this Agreement
         restricts in any way any rights of the WCB's shareholders and directors
         at any time after the Effective Date to nominate, elect, select, or
         remove WCB's directors.

         6.4. EMPLOYEES. WCB presently intends to allow the Bank's employees who
         are employed with the Combined Corporation following the Transaction
         ("Continuing Employees") to participate in certain employee benefit
         plans in which employees of WCB and HB currently participate. WCB
         intends to grant Continuing Employees credit for prior service with the
         Bank for purposes of determining eligibility and vesting, but
         Continuing Employees will not receive this credit for purposes of
         determining benefit accruals. This expression of intent is not a
         contract with the Bank's employees and will not be construed to create
         a contract or employment right with the Bank's employees.

         6.5. EMPLOYEE BENEFIT ISSUES.

              6.5.1. COMPARABILITY OF BENEFITS. WCB confirms to VB its present
              intention to provide Continuing Employees with employee benefit
              programs which, in the aggregate, are generally not less favorable
              than those being provided to WCB employees.

              6.5.2. TRANSFER OR MERGER OF GROUP PLAN. As soon as practicable
              after Closing, VB's employee benefit plans will be terminated and
              the interests of VB's employees in those plans will be transferred
              or merged into WCB's employee benefit plans.

              6.5.3. NO CONTRACT CREATED. Except as provided in Subsection 6.2,
              Nothing in this Agreement gives any VB employee a right to
              continuing employment.

                                   SECTION 7.
                          TERMINATION OF AGREEMENT AND
                           ABANDONMENT OF TRANSACTION

         7.1. TERMINATION BY REASON OF LAPSE OF TIME. If Closing does not occur
         before the Termination Date, either WCB or VB may terminate this
         Agreement and the Transaction if all of the following conditions are
         present:

              (a)   the terminating party's board of directors decides to
                    terminate by a majority vote of its members;

              (b)   the terminating party delivers to the other party written
                    notice that its board of directors has voted in favor of
                    termination; and

              (c)   the failure to consummate the Merger by the Termination Date
                    is not due to a breach by the 

                                      -44-
<PAGE>   168
                    party seeking termination of any of its obligations,
                    representations or warranties under this Agreement.

         7.2. OTHER GROUNDS FOR TERMINATION. This Agreement and the Transaction
         may be terminated at any time before Closing (whether before or after
         applicable approval of this Agreement by VB's shareholders, unless
         otherwise provided) as follows:

              7.2.1. MUTUAL CONSENT. By mutual consent of the parties to this
              Agreement, if the boards of directors of each party agrees to
              terminate by a majority vote of its members.

              7.2.2. CONDITIONS OF VB NOT MET. By WCB's board of directors if,
              by October 31, 1996, any condition set forth in Subsections 5.1 or
              5.2 has not been satisfied.

              7.2.3. VB FAILS TO RECOMMEND STOCKHOLDER APPROVAL OR TRIGGERING
              EVENT OCCURS. By WCB's board of directors (a) before VB's
              shareholders approve the Transaction, if VB's board of directors:
              (1) fails to recommend to its stockholders the approval of the
              Transaction or (2) modifies, withdraws or changes in a manner
              adverse to WCB its recommendation to shareholders to approve the
              Transaction; or (b) an Initial Triggering Event (as defined in the
              Stock Option Agreement), and a Subsequent Triggering Event (as
              defined in the Stock Option Agreement) occur, unless WCB exercises
              the Stock Option Agreement.

              7.2.4. CONDITIONS OF WCB OR HB NOT MET. By VB's board of directors
              if, by October 31, 1996, any condition set forth in Subsections
              5.1 or 5.3 has not been satisfied.

              7.2.5. DECLINE IN VALUE OF WCB STOCK. By VB's board of directors,
              in accordance with the following provisions:

                    (a) Subject to Subsection 7.2.5.(b), at any time during the
                        three-business-day period commencing on the fifth
                        calendar day preceding the Effective Date (the
                        "Determination Date"), if both of the following
                        conditions are satisfied:

                        (1) The Modified Average Closing Price (determined for
                            purposes of this Subsection 7.2.5.(a)(1) as the
                            Average Closing Price without the limitations set
                            forth in the second sentence of Subsection 1.3.3) is
                            less than $15.30; and

                                      -45-
<PAGE>   169
                        (2) The number, expressed as a percentage, obtained by
                            dividing the Modified Average Closing Price by
                            $17.00 is more than five percentage points less than
                            the Index Differential.

                    (b) If VB exercises its termination right under Subsection
                        7.2.5.(a), it will give immediate written notice to WCB.
                        If VB gives this notice, the Effective Date will
                        automatically be postponed to a date ("Postponed
                        Effective Date") 10 business days from the date of this
                        notice, unless the parties agree on another date, and
                        all references to the Effective Date in this Agreement,
                        except in Subsections 1.3.3, 2.1, 7.2.5.(a) and
                        7.2.5.(b), will mean the Postponed Effective Date.
                        Unless Subsection 7.2.5.(c) applies, during the five-
                        business-day period beginning on the day WCB receives
                        VB's termination notice, WCB has the option to increase
                        the consideration to be received by VB shareholders by
                        using the Modified Average Closing Price in place of the
                        Average Closing Price. If WCB so elects within the
                        five-business-day period, it will give immediate written
                        notice to VB, and no termination will have occurred
                        under this Subsection 7.2.5, and this Agreement will
                        remain in effect in accordance with its terms (except
                        for the substitution of the Modified Average Closing
                        Price for the Average Closing Price and Postponed
                        Effective Date for Effective Date).

                    (c) At any time during the three-business-day period
                        commencing on the Determination Date, if the Modified
                        Average Closing Price is less than $13.60. If VB
                        exercises this right, it will give immediate written
                        notice to WCB.

                    (d) For purposes of this Subsection 7.2.5, the terms listed
                        below have the following meanings:

                        (1) Index Price. For any member of the Index Group, the
                            Modified Average Closing Price calculated using,
                            instead of WCB stock, the common stock of that
                            member of the Index Group.

                        (2) Index Differential. The sum of the respective
                            numbers (expressed as percentages), for each of the
                            members of the Index Group, obtained by multiplying
                            the weighting (as set forth in Schedule 14) of that
                            member of the Index Group times the quotient of the
                            Index Price for that member of the Index Group
                            divided by the Base Price (as set forth in 

                                      -46-
<PAGE>   170
                            Schedule 14) for that member of the Index Group.

                        (3) Index Group. The companies set forth in chart form
                            in Schedule 14, the common stock of all of which
                            will be publicly traded and as to which no publicly
                            announced Acquisition Proposal for the company will
                            have been made between the day before the date this
                            Agreement is signed and the Determination Date.

                        (4) Acquisition Proposal. A company within the Index
                            Group has received an Acquisition Proposal if it
                            receives a proposal for a transaction, which if
                            consummated as proposed would immediately thereafter
                            result in its equity holders' controlling 50% or
                            less of the equity of the entity resulting from the
                            combination.

                    (e) If the common stock of any of the companies listed in
                        Schedule 14 ceases to be publicly traded or an
                        Acquisition Proposal is announced with respect to that
                        company between the day before the date this Agreement
                        is signed and the Determination Date, that company will
                        be removed from the Index Group, and the weights
                        attributed to the remaining companies will be adjusted
                        proportionately for purposes of determining the Index
                        Price.

                    (f) All prices per share under this Subsection 7.2.5 will be
                        appropriately adjusted to account for stock dividends,
                        split-ups, mergers, combinations, conversions, exchanges
                        of shares or the like.

               7.2.6.   IMPRACTICABILITY. By either WCB, HB, or VB upon written
               notice given to the other parties if the party seeking
               termination under this Subsection 7.2.6's board of directors has
               determined in its sole judgment, made in good faith and after due
               consideration and consultation with counsel, that the Transaction
               has become inadvisable or impracticable by reason of the
               institution of litigation by the federal government or the
               government of either the State of Washington or the State of
               Oregon to restrain or invalidate the transactions contemplated by
               this Agreement.

         7.3. COST ALLOCATION UPON TERMINATION. In connection with the
         termination of this Agreement under this Section 7, VB, WCB and HB each
         will pay their own out-of-pocket costs incurred in connection with this
         Agreement, and will have no other liability to any other party.

         8.2. WAIVERS AND EXTENSIONS. Subject to Section 9, WCB, HB or VB may
         grant waivers or extensions to the other parties to this Agreement, but
         only through a written instrument executed by the Chief Executive
         Officer of the party granting the waiver or extension. Waivers or
         extensions which do not comply with the preceding sentence are not
         effective. In accordance with this Section 8.2, a party may extend the
         time for the performance of any of the obligations or other acts of any
         other party, and may waive:

              (a)   any inaccuracies of any other party in the representations
                    and warranties contained in this Agreement or in any
                    document delivered in connection with this Agreement;

<PAGE>   172
              (b)   compliance with any of the covenants of any other party; and

              (c)   any other party's performance of any obligations under this
                    Agreement and any other condition precedent set out in
                    Section 5.

         8.3. GENERAL INTERPRETATION. Except as otherwise expressly provided in
         this Agreement or unless the context clearly requires otherwise: (1)
         the defined terms defined in this Agreement include the plural as well
         as the singular and (2) references in this Agreement to Sections,
         Subsections, Schedules, and Exhibits refer to Sections and Subsections
         of and Schedules and Exhibits to this Agreement. Whenever the words
         "include", "includes", or "including" are used in this Agreement, the
         parties intend them to be interpreted as if they are followed by the
         words "without limitation." All pronouns used in this Agreement include
         the masculine, feminine and neuter gender, as the context requires. All
         accounting terms used in this Agreement that are not expressly defined
         in this Agreement have the respective meanings given to them in
         accordance with GAAP.

         8.4. CONSTRUCTION AND EXECUTION IN COUNTERPARTS. Except as otherwise
         expressly provided in this Agreement, this Agreement: (1) contains the
         parties' entire understanding, and no modification or amendment of its
         terms or conditions will be effective unless in writing and signed by
         the parties, or their respective duly authorized agents; (2) will not
         be interpreted by reference to any of the titles or headings to the
         Sections or Subsections, which have been inserted for convenience only
         and are not deemed a substantive part of this Agreement; (3) includes
         all amendments to this Agreement, each of which is made a part of this
         Agreement by this reference; and (4) may be executed in one or more
         counterparts, each of which will be deemed an original, but all of
         which taken together will constitute one and the same document.

         8.5. SURVIVAL OF REPRESENTATIONS, WARRANTIES, AND COVENANTS. Except for
         Subsection 4.8 (confidentiality) and Subsection 7.3 (expense
         allocation), the representations, warranties and covenants in this
         Agreement will not survive Closing or termination of this Agreement.

         8.6. ATTORNEYS' FEES AND COSTS. In the event of any dispute or
         litigation with respect to the terms and conditions or enforcement of
         rights or obligations arising by reason of this Agreement or the
         Transaction, the prevailing party in any such litigation will be
         entitled to reimbursement from the other party for its costs and
         expenses, including reasonable judicial and extra-judicial attorneys'
         fees, expenses and disbursements, and fees, costs and expenses relating
         to any mediation or appeal.

<PAGE>   173
         8.7. ARBITRATION. At either party's request, the parties must submit
         any dispute, controversy or claim arising out of or in connection with,
         or relating to, this Agreement or any breach or alleged breach of this
         Agreement, to arbitration under the American Arbitration Association's
         rules then in effect (or under any other form of arbitration mutually
         acceptable to the parties). A single arbitrator agreed on by the
         parties will conduct the arbitration. If the parties cannot agree on a
         single arbitrator, each party must select one arbitrator and those two
         arbitrators will select a third arbitrator. This third arbitrator will
         hear the dispute. The arbitrator's decision is final (except as
         otherwise specifically provided by law) and binds the parties, and
         either party may request any court having jurisdiction to enter a
         judgment and to enforce the arbitrator's decision. The arbitrator will
         provide the parties with a written decision naming the substantially
         prevailing party in the action. This prevailing party is entitled to
         reimbursement from the other party for its costs and expenses,
         including reasonable attorneys' fees.

         8.8. GOVERNING LAW. This Agreement will be governed by and construed in
         accordance with the laws of the State of Washington, except to the
         extent that certain matters may be governed by federal law.

         8.9. SEVERABILITY. If a court determines that any term of this
         Agreement is invalid or unenforceable under applicable law, the
         remainder of this Agreement is not affected, and each remaining term is
         valid and enforceable to the fullest extent permitted by law.

                                   SECTION 9.
                                   AMENDMENTS

         9.1. BOARD ACTION. At any time before the Effective Date, whether
before or after the parties have obtained any applicable shareholder approvals
of the Transaction, the boards of directors of WCB,HB, and VB may: (1) amend or
modify this Agreement or any attached Exhibit or Schedule and (2) grant waivers
or time extensions in accordance with Subsection 8.2; but after the VB
shareholders have approved this Agreement, the parties' boards of directors may
not without VB shareholder approval amend or waive any provision of this
Agreement if the amendment or waiver would reduce the amount or change the form
of consideration VB shareholders will receive in the Transaction. All
amendments, modifications, extensions and waivers must be in writing and signed
by the party agreeing to the amendment, modification, extension or waiver.
Failure by any party to insist on strict compliance with any obligation,
agreement or condition of the other parties under this Agreement, does not
without a writing operate as a waiver or estoppel with respect to that or any
other obligation, agreement or condition.

                               AMENDMENT NO. 1 TO
                                MERGER AGREEMENT

         This Amendment No. 1, dated April 8, 1996, amends the Plan and
Agreement of Reorganization and Merger ("Merger Agreement") between West Coast
Bancorp ("WCB"), HB Acquisition Corporation ("HB") and Vancouver Bancorp ("VB"),
signed by the parties on February 15, 1996.

                                    RECITALS

A.       After the Merger Agreement was signed, it was determined that the
         numbers representing VB's and WCB's issued and outstanding shares of
         capital stock were inadvertently understated in the Merger Agreement.
         Also, due to options in the process of exercise under a WCB Stock Plan
         at the time the Merger Agreement was signed, the number representing
         the WCB Common Stock shares outstanding under the WCB Stock Plans was
         overstated in the Merger Agreement. Each party was unaware when the
         Merger Agreement was signed of these technical discrepancies in the
         other party's disclosures.

B.       The parties wish to correct their respective disclosures in the Merger
         Agreement to reflect the actual numbers of each of their issued and
         outstanding shares as of February 15, 1996, and the actual number of
         the WCB Common Stock shares outstanding under the WCB Stock Plans as of
         February 15, 1996.

         Therefore, in consideration of the mutual promises set forth below and
in the Merger Agreement, the parties amend the Merger Agreement as follows:

                                                     AGREEMENT

1.       DEFINITIONS. Capitalized terms not expressly defined in this Amendment
         No. 1 have the meaning assigned to those terms in the Merger Agreement.

2.       AMENDMENT TO WCB'S REPRESENTATIONS AND WARRANTIES. WCB's representation
         and warranty in Subsection 3.1.3(a)(1) is amended by inserting
         4,807,679 in place of 4,805,689 as the number of WCB Common Stock
         shares which are issued and outstanding. WCB's representation and
         warranty in Subsection 3.1.3(a)(2) is amended by inserting 343,431 in
         place of 344,420 as the number of WCB Common Stock shares outstanding
         under the WCB Stock Plans.

3.       AMENDMENT TO VB'S REPRESENTATIONS AND WARRANTIES. VB's representation
         and warranty in Subsection 3.1.3(b)(1) is amended by inserting 141,461
         in place of 141,428 as the number of VB Common Stock shares which are
         issued and outstanding.

4.       FULL FORCE AND EFFECT. The Merger Agreement remains in full force and
         effect, except as specifically amended by this Amendment No. 1.
<PAGE>   179
5.       GOVERNING LAW. This Amendment No. 1 is governed by Washington State
         law.

6.       COUNTERPARTS. The parties may execute this Amendment No. 1 in one or
         more counterparts. All counterparts will be construed together and
         constitute one originally executed document.

Signed as of April 8, 1996:

                                       WEST COAST BANCORP

                             STOCK OPTION AGREEMENT

         STOCK OPTION AGREEMENT ("Agreement"), dated as of February 15, 1996,
between WEST COAST BANCORP ("WCB"), an Oregon corporation, and VANCOUVER BANCORP
("VB"), a Washington corporation.

                                    RECITALS

A.       WCB, VB, and HB Corporation ("HB") are signing and delivering a Plan
         and Agreement of Reorganization and Merger ("Merger Agreement") dated
         as of February 15, 1996, concurrently with this Agreement.

B.       As a condition to and in consideration of WCB's signing of the Merger
         Agreement, VB has agreed to grant WCB the Option described in this
         Agreement.

                                    AGREEMENT

         In consideration of the mutual promises set forth in this Agreement and
in the Merger Agreement, the parties agree as follows:

1.       GRANT OF OPTION. VB grants to WCB an irrevocable option ("Option") to
         purchase, subject to the terms of this Agreement, up to 28,144 fully
         paid and nonassessable shares of VB Common Stock, no par value ("Common
         Stock") (which represents 19.9% of VB's total stock issued and
         outstanding), at a price of $64 per share; but if VB issues or agrees
         to issue any shares of Common Stock (other than as permitted under the
         Merger Agreement or in accordance with existing stock options) at a
         price less than $64 per share (as adjusted in accordance with
         Subsection 6.3), such price shall be equal to such lesser price (such
         price, as adjusted if applicable, the "Option Price"). The number of
         shares of Common Stock that may be received upon the exercise of the
         Option and the Option Price are subject to adjustment as set forth in
         this Agreement.

2.       EXERCISE OF OPTION.

         2.1      Exercise of Option. The Holder (defined below) may exercise
                  the Option, in whole or part, if, but only if, both an Initial
                  Triggering Event (defined below) and a Subsequent Triggering
                  Event (defined below) shall have occurred before the
                  occurrence of an Exercise Termination Event (defined below);
                  provided that the Holder shall have sent the written notice of
                  such exercise (as provided in Subsection 2.2) within 30 days
                  following such Subsequent Triggering Event (or such longer
                  period as provided in Section 10). This Option shall not be
                  exercisable: (a) during any period in which WCB is



                                      - 1 -
<PAGE>   181
                  failing in any material respect to perform its obligations or
                  observe its covenants under the Merger Agreement, unless the
                  reason for such failure is that VB is failing in any material
                  respect to perform its obligations or observe its covenants
                  under the Merger Agreement; (b) if any governmental approvals
                  required for the issuance of the shares of Common Stock to be
                  purchased shall not have been obtained or if such issuance
                  would violate applicable laws or regulations.

         2.2      Notice. In the event the Holder is entitled to and wishes to
                  exercise the Option, it shall send to VB a written notice (the
                  date of which is referred to in this Agreement as the "Notice
                  Date") specifying (a) the total number of shares it will
                  purchase pursuant to such exercise and (b) a place and a date
                  not earlier than three business days nor later than 30
                  business days from the Notice Date, for the closing of such
                  purchase (the "Closing Date"); provided that if the closing of
                  the purchase and sale pursuant to the Option cannot be
                  consummated by reason of any applicable judgment, decree,
                  order, law or regulation, the period of time that otherwise
                  would run pursuant to this sentence shall run instead from the
                  date on which such restriction on consummation has expired or
                  been terminated; and provided further that if prior
                  notification to or approval of the Board of Governors of the
                  Federal Reserve System ("Federal Reserve Board") or any other
                  regulatory agency is required in connection with such
                  purchase, the Holder shall promptly file the required notice
                  or application for approval and shall expeditiously process
                  the same and the period of time that otherwise would run
                  pursuant to this sentence shall run instead from the date on
                  which any required notification periods have expired or been
                  terminated or such approvals have been obtained and any
                  requisite waiting period or periods shall have passed. Any
                  exercise of the Option shall be deemed to occur on the Notice
                  Date relating thereto.

         2.3      Payment. At the closing referred to in Subsection 2.2, the
                  Holder shall pay to VB the aggregate purchase price for the
                  shares of Common Stock purchased pursuant to the exercise of
                  the Option in immediately available funds by wire transfer to
                  a bank account designated by VB, provided that failure or
                  refusal of VB to designate such an account shall not preclude
                  the Holder from exercising the Option. At such closing,
                  simultaneously with the delivery of immediately available
                  funds as provided in this Subsection 2.3, VB shall deliver to
                  the Holder a certificate or certificates representing the
                  number of shares of Common Stock purchased by the Holder and,
                  if the Option is exercised in part only, a new Option
                  evidencing the rights of the Holder thereof to purchase the
                  balance of the shares purchasable under this


                                      - 2 -
<PAGE>   182
                  Agreement and the Holder shall deliver to VB a copy of this
                  Agreement and a letter agreeing that the Holder will not offer
                  to sell or otherwise dispose of such shares in violation of
                  applicable law or the provisions of this Agreement.

         2.4      Legend. Certificates for Common Stock delivered at a closing
                  under this Agreement may be endorsed with a restrictive legend
                  that shall read substantially as follows:

                        "The transfer of the shares represented by this
                        certificate is subject to certain provisions of an
                        agreement between the registered holder hereof and VB
                        and to resale restrictions arising under the Securities
                        Act of 1933, as amended, and applicable state securities
                        laws. A copy of such agreement is on file at the
                        principal office of VB and will be provided to the
                        holder hereof without charge upon receipt by VB of a
                        written request therefor."

                  It is understood and agreed that: (a) the reference to the
                  resale restrictions of the Securities Act of 1933, as amended
                  ("1933 Act"), in the above legend shall be removed by delivery
                  of substitute certificate(s) without such reference if the
                  Holder shall have delivered to VB a copy of a letter from the
                  staff of the Securities and Exchange Commission ("SEC"), or an
                  opinion of counsel, in form and substance satisfactory to VB,

                        obligation contained in the Merger Agreement and such
                        breach: (1) would entitle WCB to terminate the Merger
                        Agreement (without regard for any cure periods, if any,
                        provided therein unless such cure is promptly effected
                        without jeopardizing consummation of the merger pursuant
                        to the terms of the Merger Agreement) and (2) shall not
                        have been cured prior to the Notice Date; or

                  e.    Any person other than WCB or any WCB Subsidiary, other
                        than in connection with a transaction to which WCB has
                        given its prior written consent, shall have filed an
                        application or notice with the Federal Reserve Board, or
                        other federal or state bank regulatory authority, which
                        application or notice has been accepted for processing,
                        for approval to engage in an Acquisition Transaction.

         3.4      Subsequent Triggering Event. The term "Subsequent Triggering
                  Event" means either of the following events or transactions
                  occurring after the date of this Agreement (it being
                  understood that the occurrence of either such event would also
                  constitute an Initial Triggering Event):

                  a.    The acquisition by any person, alone or together with
                        such person's affiliates and associates, or any group,
                        subject to the same exceptions as those set forth in
                        Subsections 3.3.b(1) and 3.3.b(2), of beneficial 
                        ownership of 25% or more of the then outstanding Common
                        Stock; or

                  b.    The occurrence of an Initial Triggering Event described
                        in Subsection 3.3.a, except that the percentage
                        referred to in clause (3) shall be 25%.

         3.5      Triggering Event and Notice. VB shall notify WCB promptly in
                  writing of the occurrence of any Initial Triggering Event or
                  Subsequent Triggering Event (collectively, a "Triggering
                  Event"), it being understood that the giving of such notice by
                  VB shall not be a condition to the right of the Holder to
                  exercise the Option.

4.       COVENANTS OF VB. VB agrees that: (a) it shall at all times maintain,
         free from preemptive rights, sufficient authorized but unissued or
         treasury shares of Common Stock so that the Option may be exercised
         without additional authorization of Common Stock after giving effect to
         all other options, warrants, convertible securities and other rights to
         purchase Common Stock; (b) it shall 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 by VB


                                      - 6 -
<PAGE>   186
         under this Agreement; (c) it shall promptly take all action as may from
         time to time be required (including (1) complying with all premerger
         notification, reporting and waiting period requirements specified in 15
         U.S.C. Section 18a and regulations promulgated thereunder and (2) if,
         under the Bank Holding Company Act of 1956, as amended, or the Change
         in Bank Control Act of 1978, as amended, or any 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 the 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 the Holder to exercise the Option and VB duly and
         effectively to issue shares of Common Stock in accordance with this
         Agreement; and (d) it shall promptly take all action provided in this
         Agreement to protect the rights of the Holder against dilution.

5.       EXCHANGE OF OPTION. This Agreement (and the Option granted by this
         Agreement) are exchangeable, without expense, at the option of the
         Holder, upon presentation and surrender of this Agreement at VB's
         principal office, for other Agreements providing for Options of
         different denominations entitling the Holder thereof to purchase, on
         the same terms and subject to the same conditions as are set forth in
         this Agreement, in the aggregate, the same number of shares of Common
         Stock purchasable under this Agreement. The terms "Agreement" and
         "Option" as used in this Agreement include any Stock Option Agreements
         and related Options for which this Agreement (and the Option granted by
         this Agreement) may be exchanged. Upon receipt by VB 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, VB 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 VB, whether or not the Agreement
         so lost, stolen, destroyed or mutilated shall at any time be
         enforceable by anyone.

6.       ANTI-DILUTION ADJUSTMENTS. The number of shares of Common Stock
         purchasable upon the exercise of the Option and the Option Price shall
         be subject to adjustment from time to time as follows:

         6.1      In the event of any change in Common Stock by reason of stock
                  dividends, split-ups, mergers, recapitalizations,
                  combinations, subdivisions, conversions, exchanges of shares
                  or the like, the type and number of shares of Common Stock
                  purchasable upon exercise hereof shall be appropriately
                  adjusted, and proper provision shall be made in the agreements
                  governing such transaction so that WCB shall receive upon
                  exercise of the Option the number



                                      - 7 -
<PAGE>   187
                  and class of shares, other securities, property or cash that
                  WCB would have received in respect of the Common Stock subject
                  to the Option if the Option had been exercised and the Common
                  Stock subject to the Option had been issued to WCB immediately
                  prior to such event or the record date therefor, as
                  applicable.

         6.2      In the event that any additional shares of Common Stock are
                  issued or otherwise become outstanding after the date of this
                  Agreement (other than as described in Section 6.1 or pursuant
                  to this Agreement), including, without limitation, pursuant to
                  stock option plans and in connection with acquisitions and
                  other transactions permitted by the Merger Agreement, the
                  number of shares of Common Stock subject to the Option shall
                  be increased so that, after such issuance, it equals 19.9% of
                  the number of shares of Common Stock then issued and
                  outstanding without giving effect to any shares subject or
                  issued pursuant to the Option. Nothing contained in this
                  Agreement shall be deemed to authorize VB or WCB to breach any
                  provision of the Merger Agreement.

         6.3      Subject to the following sentence, whenever the number of
                  shares of Common Stock purchasable upon exercise hereof is
                  adjusted as provided in this Section 6, the Option Price shall
                  be adjusted by multiplying the Option Price by a fraction, the
                  numerator of which shall be equal to the number of shares of
                  Common Stock purchasable prior to the adjustment and the
                  denominator of which shall be equal to the number of shares of
                  Common Stock purchasable after the adjustment. The foregoing
                  adjustment to the Option Price shall not apply to adjustments
                  in the number of shares of Common Stock issuable under this
                  Option caused by an issuance of additional shares of Common
                  Stock for consideration pursuant to an agreement entered into
                  before the date of this Agreement.

         6.4      In no event shall the aggregate number of shares for which
                  this Option is exercisable (including pursuant to all
                  adjustments as provided for in this Agreement) exceed 19.9% of
                  VB's outstanding Common Stock prior to exercise.

7.       REGISTRATION RIGHTS. Upon the occurrence of a Subsequent Triggering
         Event that occurs before an Exercise Termination Event, VB shall, at
         the request of WCB delivered within 30 days of such Subsequent
         Triggering Event (whether on its own behalf or on behalf of any
         subsequent Holder of this Option (or part thereof) or any of the shares
         of Common Stock issued pursuant to this Agreement), promptly prepare,
         file and keep current a shelf registration statement under the 1933 Act
         covering the Option and any shares issued and issuable pursuant to this
         Option and shall use its best efforts to cause such registration
         statement to become effective and remain current in order to permit the
         sale or other



                                      - 8 -
<PAGE>   188
         disposition of any shares of Common Stock issued upon total or partial
         exercise of this Option ("Option Shares") in accordance with any plan
         of disposition requested by WCB. VB will use its best efforts to cause
         such registration statement first to become effective and then to
         remain effective for such period not in excess of 180 days from later
         of (i) the date of the closing under this Agreement or (ii) the date
         such registration statement first becomes effective, or such shorter
         time as may be reasonably necessary to effect such sales or other
         dispositions. WCB shall have the right to demand two such
         registrations. The obligations of VB under this Agreement to file a
         registration statement and to maintain its effectiveness may be
         suspended for one or more periods of time that do not exceed 60 days in
         the aggregate if VB's board of directors shall have determined that the
         filing of such registration statement or the maintenance of its
         effectiveness would require disclosure of nonpublic information that
         would materially and adversely affect VB. The foregoing
         notwithstanding, if at the time of any request by WCB for registration
         of the Option and/or the Option Shares as provided above, VB is in
         registration with respect to an underwritten public offering of shares
         of Common Stock, and if in the good faith judgment of the managing
         underwriter or managing underwriters, or, if none, the sole underwriter
         or underwriters, of such offering the inclusion of the Option and/or
         Option Shares would interfere with the successful marketing of the
         shares of Common Stock offered by VB, the number of Option Shares which
         in either case are to be covered in the registration statement
         contemplated by this Agreement may be reduced; provided, however, that
         after any such required reduction the number of Option Shares to be
         included in such offering for the account of the Holder shall
         constitute at least 25% of the total number of shares to be sold by the
         Holder and VB in the aggregate; and provided further, however, that if
         such reduction occurs, then VB shall file a registration statement for
         the balance as promptly as practical and no reduction shall thereafter
         occur. Each Holder whose Option and/or Option Shares are registered
         under this Agreement shall provide all information reasonably requested
         by VB for inclusion in any registration statement to be filed under
         this Agreement. If requested by any such Holder in connection with such
         registration, VB shall become a party to any underwriting agreement
         relating to the sale of such shares, but only to the extent of
         obligating itself in respect of representations, warranties,
         indemnities and other agreements customarily included in such
         underwriting agreements for the VB. Upon receiving any request under
         this Section 7 from any Holder, VB agrees to send a copy thereof to any
         other person known to VB to be entitled to registration rights under
         this Section 7, in each case by promptly mailing the said postage
         prepaid, to the address of record of the persons entitled to receive
         such copies.

8.       REPURCHASE OF OPTION OR OPTION SHARES.

         8.1      Repurchase of Option or Option Shares. Upon the occurrence of
                  a Subsequent Triggering Event that occurs prior to an Exercise
                  Termination Event, (a) at the request of the Holder, delivered
                  within 30 days of such occurrence (or such longer period as
                  provided in Section 10), VB shall repurchase the Option from
                  the Holder at a price (the "Option Repurchase Price") equal to
                  the product of the excess of (i) the Market/Offer Price (as
                  defined below) over (ii) the Option Price, multiplied by the
                  number of shares for which this Option may then be exercised,
                  and (b) at the request of the owner of Option Shares from time
                  to time (the "Owner"), delivered within 30 days of such
                  occurrence (or such later period as provided in Section 10),
                  VB shall repurchase such number of the Option Shares from the
                  Owner as the Owner shall designate at a price (the "Option
                  Share Repurchase Price") equal to the product of the
                  Market/Offer Price multiplied by the number of Option Shares
                  so designated. The term "Market/Offer Price" means the highest
                  of the following amounts with respect to the six-month period
                  immediately preceding the date the Holder gives notice of the
                  required repurchase of this Option or the Owner gives notice
                  of the required repurchase of Option Shares, as the case may
                  be (a) the price per share of Common Stock at which a tender
                  offer or exchange offer therefor has been made; (b) the price
                  per share of Common Stock paid by any third party or to be
                  paid pursuant to an agreement with VB entered into during the
                  period; (c) the highest closing price for shares of Common
                  Stock reported in the principal market for such shares within
                  the period; or (d) in the event of a sale of all or
                  substantially all of VB's assets, the sum of the price paid in
                  such sale for such assets and the current market value of the
                  remaining assets of VB as determined by a nationally
                  recognized investment banking firm selected by the Holder or
                  the Owner, as the case may be, and VB divided by the number of
                  shares of Common Stock of VB outstanding at the time of such
                  sale. In determining the Market/Offer Price, the value of
                  consideration other than cash shall be determined by a
                  nationally recognized investment banking firm selected by the
                  Holder or Owner, as the case may be, and VB. Notwithstanding
                  the foregoing, if the same person who has participated in a
                  Triggering Event has entered, or after such Triggering Event
                  has occurred enters, into any agreement or understanding with
                  WCB relating to WCB's rights under this Option or with respect
                  to the Option Shares or directly or indirectly relating to VB,
                  WCB shall, notwithstanding the terms of such agreement or
                  understanding, at any time upon the occurrence of a Subsequent
                  Triggering Event of the type set forth in Subsection without
                  VB's approval, recommendation or consent, promptly request
                  that VB



                                     - 10 -
<PAGE>   190
                  repurchase the Option and any Option Shares held by WCB as
                  provided in this Section 8 and VB shall do so.

         8.2      Holder Election. The Holder and/or the Owner, as the case may
                  be, may exercise its right to require VB to repurchase the
                  Option and any Option Shares pursuant to this Section 8 by
                  surrendering for such purpose to VB, at its principal office,
                  a copy of this Agreement or certificates for Option Shares, as
                  applicable, accompanied by a written notice or notices stating
                  that the Holder or the Owner, as the case may be, elects to
                  require VB to repurchase this option and/or the Option Shares
                  in accordance with the provisions of this Section 8. As
                  promptly as practicable, and in any event within five business
                  days after the surrender of the Option and/or certificates
                  representing Option Shares and the receipt of such notice or
                  notices relating thereto, VB shall deliver or cause to be
                  delivered to the Holder the Option Repurchase Price and/or to
                  the Owner the Option Share Repurchase Price therefor or the
                  portion thereof that VB is not then prohibited under
                  applicable law and regulation from so delivering.

         8.3      Prohibitions of Law. To the extent that VB is prohibited under
                  applicable law or regulation, or as a consequence of
                  administrative policy, from repurchasing the Option and/or the
                  Option Shares in full, VB shall immediately so notify the
                  Holder and/or the owner and thereafter deliver or cause to be
                  delivered, from time to time, to the Holder and/or the Owner,
                  as appropriate, the portion of the Option Repurchase Price and
                  the Option Share Repurchase Price, respectively, that it is no
                  longer prohibited from delivering, within five business days
                  after the date on which VB is no longer so prohibited;
                  provided, however, that if VB at any time after delivery of a
                  notice of repurchase pursuant to Subsection 8.2 is prohibited
                  under applicable law or regulation, or as a consequence of
                  administrative policy, from delivering to the Holder and/or
                  the Owner, as appropriate, the Option Repurchase Price and the
                  Option Share Repurchase Price, respectively, in full (and VB
                  hereby undertakes to use its best efforts to obtain all
                  required regulatory and legal approvals and to file any
                  required notices as promptly as practicable in order to
                  accomplish such repurchase), the Holder and/or Owner may
                  revoke its notice of repurchase of the Option or the Option
                  Shares either in whole or to the extent of the prohibition,
                  whereupon, in the latter case, VB shall promptly (a) deliver
                  to the Holder and/or the Owner, as appropriate, that portion
                  of the Option Purchase Price or the Option Share Repurchase
                  Price that VB is not prohibited from delivering; and (b)
                  deliver as appropriate, (1) to the Holder, a new Stock Option
                  Agreement evidencing the right of the Holder to purchase that
                  number of shares of Common


                                     - 11 -
<PAGE>   191
                  Stock obtained by multiplying the number of shares of Common
                  Stock for which the surrendered Stock Option Agreement was
                  exercisable at the time of delivery of the notice of
                  repurchase by a fraction, the numerator of which is the Option
                  Repurchase Price less the portion thereof theretofore
                  delivered to the Holder and the denominator of which is the
                  Option Repurchase Price, and/or (2) to the Owner, a
                  certificate for the Option Shares it is then so prohibited
                  from repurchasing, and VB shall have no further obligation to
                  purchase such Option or Option Shares.

9.       ISSUANCE OF SUBSTITUTE OPTION UPON CERTAIN MERGERS, ETC.

         9.1      Issuance of Substitute Option. In the event that before an
                  Exercise Termination Event, VB shall enter into an agreement
                  (a) to consolidate with or merge into any person, other than
                  WCB or one of its Subsidiaries, and shall not be the
                  continuing or surviving corporation of such consolidation or
                  merger; (b) to permit any person, other than WCB or one of its
                  Subsidiaries, to merge into VB and VB shall be the continuing
                  or surviving corporation, but, in connection with such merger,
                  the then outstanding shares of Common Stock shall be changed
                  into or exchanged for stock or other securities of any other
                  person or cash or any other property or the then outstanding
                  shares of Common Stock shall after such merger represent less
                  than 50% of the outstanding shares and share equivalents of
                  the merged company; or (c) to sell or otherwise transfer all
                  or substantially all of its assets to any person, other than
                  WCB or one of its Subsidiaries then, and in each such case,
                  the agreement governing such transaction shall make proper
                  provision so that the Option shall, upon the consummation of
                  any such transaction and upon the terms and conditions set
                  forth in this Agreement, be converted into, or exchanged for,
                  an option (the "Substitute Option"), at the election of the
                  Holder, of either (1) the Acquiring Corporation (as defined
                  below), (2) any person that controls the Acquiring
                  Corporation, or (3) in the case of a merger described in
                  clause (b) of this Subsection 9.1, VB.

         9.2      Definitions. The following terms have the meanings indicated:

                  a.    "Acquiring Corporation" means (1) the continuing or
                        surviving corporation of a consolidation or merger with
                        VB (if other than VB); (2) VB in a merger in which VB is
                        the continuing or surviving person; and (3) the
                        transferee of all or substantially all of VB's assets.


                                     - 12 -
<PAGE>   192
                  b.    "Substitute Common Stock" means the common stock of the
                        issuer of the Substitute Option upon exercise of the
                        Substitute Option.

                  c.    "Assigned Value" means the Market/Offer Price, as
                        defined in Section 8; provided, however, that in the
                        event a sale of all or substantially all of VB's assets,
                        the Assigned Value shall be the sum of the price paid in
                        such sale for such assets and the current market value
                        of the remaining assets of VB as determined by a
                        nationally recognized investment banking firm selected
                        by Holder, divided by the number of shares of Common
                        Stock of VB outstanding at the time of such sale.

                  d.    "Average Price" means the average closing price of a
                        share of the 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 VB is the issuer of the Substitute
                        Option, the Average Price shall be computed with respect
                        to a share of common stock issued by the person merging
                        into VB or by any company which controls or is
                        controlled by such person, as the Holder may elect.

         9.3      Exercise of Substitute Option. The Substitute Option shall be
                  exercisable for such number of shares of Substitute Common
                  Stock as is equal to the Assigned Value multiplied by the
                  number of shares of Common Stock for which the Option is then
                  exercisable, divided by the Average Price. The exercise price
                  of the Substitute Option per share of Substitute Common Stock
                  shall then be equal to the Option Price multiplied by a
                  fraction, the numerator of which shall be the number of shares
                  of Common Stock for which the Option is then exercisable and
                  the denominator of which shall be the number of shares of
                  Substitute Common Stock for which the Substitute Option is
                  exercisable.

         9.4      Terms of Substitute Option. 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 (including, without limitation,
                  those relating to repurchase of the Option and the Option
                  Shares) shall be as similar as possible and in no event less
                  advantageous to the Holder. The issuer of the Substitute
                  Option shall also enter into an agreement with the then Holder
                  of the Substitute Option in substantially the same form as
                  this Agreement, which shall be applicable to the Substitute
                  Option. The number of shares issuable and the exercise price
                  under the


                                     - 13 -
<PAGE>   193
                  Substitute Option shall be subject to adjustment in the manner
                  provided in Sections 6.1 and 6.3 of this Agreement, but,
                  notwithstanding the foregoing, adjustments to the number of
                  shares issuable and the exercise price per share resulting
                  from the application of Section 6.2, and the price adjustment
                  provided for in the first sentence of Section 1, shall not
                  apply to such Substitute Option.

         9.5      Limitation on Exercise of Substitute Option. In no event,
                  pursuant to any of the foregoing paragraphs, shall the
                  Substitute Option be exercisable for more than 19.9% 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 shares of Substitute Common Stock outstanding before
                  exercise but for this Subsection 9.5, the issuer of the
                  Substitute Option (the "Substitute Option VB") shall make a
                  cash payment to the Holder equal to the excess of (a) the
                  value of the Substitute Option without giving effect to the
                  limitation in this clause 9.5 over (b) the value of the
                  Substitute Option after giving effect to the limitation in
                  this Subsection 9.5. This difference in value shall be
                  determined by a nationally recognized investment banking firm
                  selected by the Holder.

         9.6      Assumption of Agreement. VB shall not enter into any
                  transaction described in Subsection 9.1 unless the Acquiring
                  Corporation and any person that controls the Acquiring
                  Corporation assumes in writing all the obligations of VB under
                  this Agreement.

10.      EXTENSION OF TIME PERIOD. The 30-day periods for exercise of certain
         rights under Sections 2, 7, 8, and 12 shall be extended so that each
         such period expires 30 days after all regulatory approvals required for
         the exercise of such rights have been obtained and all statutory
         waiting periods have expired; and shall be further extended to the
         extent necessary to avoid liability under Section 16(b) of the 1934 Act
         by reason of such exercise. No such extensions shall extend the period
         for the Holder to exercise the Option to a date more than 2 years after
         the date of this Agreement.

11.      VB'S REPRESENTATIONS AND WARRANTIES. VB represents and warrants to WCB
         as follows:

         11.1     Authority. VB has full corporate power and authority to
                  execute and deliver this Agreement and to consummate the
                  transactions contemplated by this Agreement. The execution and
                  delivery of this Agreement and the consummation of the
                  transactions contemplated by this Agreement have been duly and
                  validly authorized by VB's board of directors and no other
                  corporate proceedings on


                                     - 14 -

                  the part of VB are necessary to authorize this Agreement or to
                  consummate the transactions so contemplated. This Agreement
                  has been duly and validly executed and delivered by VB. This
                  Agreement is the valid and legally binding obligation of VB.

         11.2     Corporate Action. VB has taken all necessary corporate action
                  to authorize and reserve and to permit it to issue, and at all
                  times from the date of this Agreement through the termination
                  of this Agreement in accordance with its terms will have
                  reserved for issuance upon the exercise of the Option, that
                  number of shares of Common Stock equal to the maximum number
                  of shares of Common Stock at any time and from time to time
                  issuable under this Agreement, and all such shares, upon
                  issuance pursuant to this Agreement will be duly authorized,
                  validly issued, fully paid, nonassessable, and will be
                  delivered free and clear of all claims, liens, encumbrances
                  and security interests and not subject to any preemptive
                  rights.

12.      ASSIGNMENT. Neither of the parties may assign any of its rights or
         obligations under this Agreement or the Option created under this
         Agreement to any other person, without the express written consent of
         the other party, except that in the event a Subsequent Triggering Event
         shall have occurred before an Exercise Termination Event, WCB, subject
         to the express provisions of this Agreement, may assign in whole or in
         part its rights and obligations under this Agreement within 30 days
         following such Subsequent Triggering Event (or such longer period as
         provided in Section 10); provided, however, that until the date 30 days
         following the date on which the Federal Reserve Board approves an
         application by WCB under the Bank Holding Company Act to acquire the
         shares of Common Stock subject to the Option, WCB may not assign its
         rights under the Option except in (a) a widely dispersed public
         distribution; (b) a private placement in which no one party acquires
         the right to purchase in excess of 2% of the voting shares of VB; (c)
         an assignment to a single party (e.g., a broker or investment banker)
         for the purpose of conducting a widely dispersed public distribution on
         WCB's behalf; or (d) any other manner approved by the Federal Reserve
         Board. Any assignment by WCB shall be made only in compliance with
         federal and applicable state securities laws.

13.      BEST EFFORTS. Each of WCB and VB will use its best efforts to make all
         filings with, and to obtain consents of, all third parties and
         governmental authorities necessary to the consummation of the
         transactions contemplated by this Agreement, including without
         limitation making application to list the shares of Common Stock
         issuable under this Agreement on any securities exchange on which the
         Common Stock is then traded and applying to the Federal Reserve Board
         under the Bank Holding Company Act for approval to acquire the shares
         issuable under this Agreement, but WCB shall not be obligated to apply
         to state banking authorities for approval to acquire


                                     - 15 -
<PAGE>   195
         the shares of Common Stock issuable under this Agreement until such
         time, if ever, as it deems appropriate to do so.

14.      TERMINATION OF OPTION. Notwithstanding anything to the contrary in this
         Agreement, in the event that the Holder or Owner or any Related Person
         (as defined below) thereof is a person making an offer or proposal to
         engage in an Acquisition Transaction (other than the transaction
         contemplated by the Merger Agreement), then (a) in the case of a Holder
         or any Related Person thereof, the Option held by it shall immediately
         terminate and be of no further force or effect, and (b) in the case of
         an Owner or any Related Person thereof, the Option Shares held by it
         shall be immediately repurchasable by VB at the Option Price. A
         "Related Person" of a Holder or Owner means any "affiliate" (as defined
         in Rule 12b-2 of the rules and regulations under the 1934 Act) of the
         Holder or Owner and any person that is the beneficial owner of 25% or
         more of the voting power of the Holder or Owner, as the case may be.

15.      EQUITABLE RELIEF. The parties to this Agreement acknowledge that
         damages would be an inadequate remedy for a breach of this Agreement by
         either party and that the obligations of the parties shall be
         enforceable by either party through injunctive or other equitable
         relief.

16.      ENFORCEABILITY. If any term, provision, covenant or restriction
         contained in this Agreement is held by a court or a federal or state
         regulatory agency of competent jurisdiction to be invalid, void or
         unenforceable, the remainder of the terms, provisions and covenants and
         restrictions contained in this Agreement shall remain in full force and
         effect, and shall in no way be affected, impaired or invalidated. If
         for any reason such court or regulatory agency determines that the
         Holder is not permitted to acquire, or VB is not permitted to
         repurchase pursuant to Section 8, the full number of shares of Common
         Stock provided in Section 1 (as adjusted pursuant to Section 6), it is
         the express intention of VB to allow the Holder to acquire or to
         require VB to repurchase such lesser number of shares as may be
         permissible, without any amendment or modification hereof.

17.      NOTICES. All notices, requests, claims, demands and other
         communications under this Agreement shall be deemed to have been duly
         given when delivered in person, by cable, telegram, telecopy or telex,
         or by registered or certified mail (postage prepaid, return receipt
         requested) at the respective addresses of the parties set forth in the
         Merger Agreement.

18.      GOVERNING LAW. This Agreement shall be governed by and construed in
         accordance with the laws of the state of Washington, regardless of the
         laws that might otherwise govern under applicable principles of
         conflicts of laws thereof.

19.      COUNTERPARTS. This Agreement may be executed in two or more
         counterparts, each of which shall be deemed to be an original, but all
         of which shall constitute one and the same agreement.

20.      EXPENSES. Except as otherwise expressly provided in this Agreement,
         each of the parties shall bear and pay all costs and expenses incurred
         by it or on its behalf in connection with the transactions contemplated
         under this Agreement, including fees and expenses of its own financial
         consultants, investment bankers, accountants and counsel.

21.      ENTIRE AGREEMENT. Except as otherwise expressly provided in this
         Agreement or in the Merger Agreement, this Agreement contains the
         entire agreement between the parties with respect to the transactions
         contemplated under this Agreement and supersedes all prior arrangements
         or understandings with respect thereof, written or oral. The terms and
         conditions of this Agreement shall inure to the benefit of and be
         binding upon the parties and their respective successors and permitted
         assigns. Nothing in this Agreement, expressed or implied, is intended
         to confer upon any party, other than the parties to this Agreement, and
         their respective successors and assigns, any rights, remedies,
         obligations or liabilities under or by reason of this Agreement, except
         as expressly provided in this Agreement.

22.      MISCELLANEOUS. Capitalized terms used in this Agreement and not defined
         in this Agreement shall have the meanings assigned to them in the
         Merger Agreement. Section and Subsection headings are for convenience
         and reference only and shall not affect the meaning or construction of
         this Agreement. Except as otherwise provided in this Agreement,
         Sections and Subsections refer to Sections and Subsections of this
         Agreement.

         IN WITNESS WHEREOF, each of the parties has caused this Agreement to be
executed on its behalf by its officers thereunto duly authorized, all as of the
date first above written.

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

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

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

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

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

         (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

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

                  (d) An amendment of the articles of incorporation that
materially reduces the number of shares owned by the shareholder to a fraction

RCW 23B.06.040; or

                  (e) Any corporate action taken pursuant to a shareholder vote

to dissent and obtain payment for their shares.

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

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

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

         (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:


<PAGE>   199

under this chapter and be accompanied by a copy of this chapter.

         (2) If corporate action creating dissenters' rights under RCW
23B.13.020 it taken without a vote of shareholders, the corporation, within ten
days after [the] effective date of such corporate action, shall notify in
writing all shareholders entitled to assert dissenters' rights that the action

<PAGE>   200



              (c) Supply a form for demanding payment that includes the date of
the first announcement to news media or to shareholders of the terms of the

              (d) Set a date by which the corporation must receive the payment

SECTION 23B.13.260   FAILURE TO TAKE ACTION.

         (1) If the corporation does not effect the proposed action within sixty

SECTION 23B.13.270   AFTER-ACQUIRED SHARES.

         (1) A corporation may elect to withhold payment required by RCW

corporate action.

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

SECTION 23B.13.280   PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR 
OFFER.

         (1) A dissenter may notify the corporation in writing of the

23B.13.270 and demand payment of the dissenter's estimate of the fair value of
the dissenter's shares and interest due, if:


<PAGE>   201



              (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.

SECTION 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.

         (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


<PAGE>   202


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.

SECTION 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

Vancouver, Washington  98666


Members of the Board:

         You have requested our opinion as to the fairness, from a financial
point of view, to the shareholders of Vancouver Bancorp and its wholly-owned
subsidiary, Bank of Vancouver ("VB" or the Company"), of the consideration to be
received by such shareholders pursuant to the terms of the Merger Agreement and
Plan of Merger, dated February 15, 1996, (the "Agreement") between VB and West
Coast Bancorp, Inc. ("WCBO").

         In connection with the proposed merger transaction (the "Merger")
whereby VB will be merged into HB Corporation, a wholly-owned subsidiary of
WCBO, each issued and outstanding share and option of the Company common stock
(along with its associated rights) at the effective time of the Merger (other
than (i) shares of holders of which are exercising appraisal rights pursuant to
applicable law and (ii) shares held directly by or indirectly by VB, 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 the amount determined by the division of $11,581,000 (the
Merger "Consideration") by the five-day average of the bid and ask prices of
WCBO common stock two days prior to the closing date, 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. 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
WCBO pursuant to the Merger, CFAI has advised Washington and Oregon community
banks regarding fairness of capital transactions. VB 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 VB's financial and related audited
financial information for the twelve months ended December 31, 1994 and for the
interim nine month period ending September 30, 1995; (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 WCBO's audited financial information for the
fiscal year ended December 31, 1995 and financial information for the 9 months
ended September 30, 1995 including the Form 10- KSB filed with the U.S.
Securities and Exchange Commission; (viii) reviewed the price ranges and
dividend history for WCBO common stock; (ix) 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 or WCBO. 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. We have not been
authorized to solicit and did not solicit other entities for purposes of a
business combination with VB.

         This opinion is based upon the information available to us and facts
and circumstances as they exist and are subject to evaluation on the date
hereof. We are not expressing any opinion

herein as to the prices at which shares of WCBO Common Stock have traded or may
trade at any future date.

         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 VB pursuant to the Agreement is fair, from a financial point of
view, to the shareholders of VB.

         We hereby consent to the reference to our firm in the proxy statement
or prospectus related to the merger transactions and to the inclusion of our
opinion as an exhibit to the proxy statement or prospectus related to the merger
transaction.

                                              Very truly yours,

         RE:      ISSUANCE OF SECURITIES BY WEST COAST BANCORP IN
                  CONNECTION WITH THE ACQUISITION OF SHARES OF
                  VANCOUVER BANCORP

Gentlemen:

         We are acting as counsel for West Coast Bancorp, an Oregon bank holding
company ("WCB"), in connection with the registration under the Securities Act of
1933, as amended (the "Act"), of a maximum of 757,000 shares of common stock of
WCB, no par value per share (the "Shares"). A Registration Statement on Form S-4
(the "Registration Statement") is being filed under the Act with respect to the
offering of the Shares pursuant to the proposed acquisition of Vancouver
Bancorp, a Washington bank holding company ("VB").

         In connection with the offering of the Shares, we have examined: (a)
the Plan and Agreement of Reorganization and Merger between WCB, HB Acquisition
Corporation and VB dated as of February 15, 1996 (the "Agreement"), attached as
Appendix A to the Prospectus/Proxy Statement, included in the Registration
Statement; (b) the Registration Statement; and (c) such other documents as we
have deemed necessary to form the opinion expressed below. As to various
questions of fact material to such opinion, where relevant facts were not
independently established, we have relied upon statements of officers of WCB.

         Based and relying solely upon the foregoing, we advise you that in our
opinion, the Shares, or any portion thereof, when issued pursuant to the
Agreement after the Registration Statement has become effective under the Act,
will be legally issued under the laws of the State of Oregon and will be fully
paid and nonassessable.

         Consent is hereby given to the filing of this opinion as an exhibit to
the Registration Statement and to the legal reference to this firm under the
caption "Certain Legal Matters" as having passed upon the validity of the
Shares. In giving this consent, we do not admit that we are experts within the
meaning of the Act.

         This opinion has been prepared solely for your use in connection with
the Registration Statement and, in that regard, may also be relied upon by the
shareholders of VB.

                                           Very truly yours,

         Re: Holding Company Merger--Tax Consequences

Ladies and Gentlemen:

         This letter responds to your request for our opinion as to certain of
the federal income tax consequences of the proposed merger (the "Merger") of
Vancouver Bancorp ("VB") into HB Acquisition Corporation ("HB"), a wholly-owned
subsidiary of West Coast Bancorp ("WCB").

         We have acted as legal counsel to HB and WCB in connection with the
Merger. For the purpose of rendering this opinion, we have examined and relied
upon originals, certified copies, or copies otherwise identified to our
satisfaction as being true copies of the originals of the following documents,
including all exhibits and schedules attached to them:

         a.       The Plan and Agreement of Reorganization and Merger, dated as
                  of February 15, 1996, between VB and WCB (the "Merger
                  Agreement");

         b.       Form S-4 Registration Statement of WCB filed with the
                  Securities and Exchange Commission on April 22, 1996;

         c.       The Proxy Statement of VB (included as part of the
                  Registration Statement);

         d.       The factual representations set forth in a letter from WCB, VB
                  and HB, dated April 5, 1996; and

         e.       Such other documents, instruments, records and information
                  pertaining to the Merger as we have deemed necessary for
                  rendering our opinion.

         We have assumed, without independent investigation or review, the
accuracy and completeness of the facts and representations and warranties
contained in those documents or otherwise made known to us, and that the Merger
will be effected in accordance with the terms of the Merger Agreement.

         In connection with the Merger and pursuant to the Merger Agreement,
each share of VB voting common stock will be exchanged for that number of shares
of WCB voting common stock based on the exchange rate established in the Merger
Agreement. WCB will remain the sole shareholder of HB. No fractional shares will
be involved. VB shareholders who perfect their dissenters rights under state law
will be paid the cash value for their VB shares. Such payments will be made by
VB without reimbursement by WCB. Upon the consummation of the Merger, HB will
continue the historic business of VB.

         Based upon our review of the facts described above and our analysis of
the law, and subject to the qualifications and limitations set forth herein, and
the completion of the transactions described in the matter contemplated, it is
our opinion that:

1.       The merger of VB into HB solely for WCB voting common stock, as
         described above, will constitute a reorganization within the meaning of
         Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal Revenue Code, as
         amended (the "Code"). VB, HB and WCB will each be a "party to a
         reorganization" within the meaning of Section 368(b) of the Code.

2.       No gain or loss will be recognized by VB shareholders upon the receipt
         of WCB voting common stock solely in exchange for their shares of VB
         stock, pursuant to Section 354(a)(1) of the Code.

3.       The basis of the shares of WCB voting common stock received by VB
         shareholders will be the same as the basis of the VB stock surrendered
         in exchange therefor, pursuant to Section 358(a)(1) of the Code.

4.       The holding period of the shares of WCB voting common stock received by
         VB shareholders will include the holding period during which the VB
         stock surrendered in exchange therefor was held, provided that the
         shares of VB stock were held as a capital asset in the hands of the
         exchanging shareholders on the date of the exchange, pursuant to
         Section 1223(1) of the Code.

5.       Where cash is received by any dissenting shareholder of VB in exchange
         for the surrender of all of such shareholder's VB stock, the cash will
         be treated as received by the shareholder as a distribution in
         redemption of his or her VB stock, subject to the provisions and
         limitation of Section 302 of the Code.

6.       No gain or loss will be recognized by VB upon the transfer of its
         assets to HB, pursuant to Sections 361 and 357(a) of the Code.

7.       The basis of the assets of VB acquired by HB will be the same as the
         basis of VB in the assets immediately before the Merger, pursuant to
         Section 362(b) of the Code.

8.       The holding period of the assets acquired by HB will include the period
         such assets were held by VB, pursuant to Section 1223(2) of the Code.

9.       No gain or loss will be recognized by WCB or HB upon the receipt by HB
         of the assets of VB, as described above.

         Our opinion represents only our best legal judgment as to the probable
federal income tax consequences of the transaction described, based upon
existing law. Our opinion is not intended to be a conclusive statement as to all
of the tax consequences of the transaction and is expressly limited to the
matters addressed. Further, our opinion is not binding upon the Internal Revenue
Service (the "IRS") or any court and has no official status of any kind, and no
private ruling regarding the matters discussed has been or will be requested
from the IRS. The IRS has ruled in a number of private rulings that transactions
substantially identical to the Merger result in tax consequences consistent with
those described in this opinion. Although such rulings do not constitute
authority on which we can rely in expressing our opinion, such rulings generally
do reflect the position of the IRS. Each shareholder, however, is urged to
consult with his or her own tax advisor with respect to their individual tax
situation. Our opinion is intended solely for the benefit of WCB, HB and the
shareholders of WCB, and may not be relied upon for any other purpose or by any
other person or entity or made available to any other person or entity without
our prior written consent.

                                     Very truly yours,

                                     GRAHAM & DUNN

                                    RECITALS

         A. West Coast has entered into a Plan and Agreement of Reorganization
and Merger with Vancouver Bancorp ("VB") pursuant to which VB will merge (the

         3. Duties. The Bank of Vancouver shall, initially, employ Stenseth as

responsibilities to accommodate management succession, as well as any other
management objectives of the Bank of Vancouver or of West Coast. Stenseth shall
faithfully and diligently perform his assigned duties. Stenseth shall assume
such additional positions, duties, and responsibilities as may properly be
requested of him without additional compensation.

         4. Extent of Services. Stenseth shall devote all of his working time,
attention and skill to the duties and responsibilities set forth in Section 3
above. To the extent that such activities do not interfere with his duties under
Section 3, Stenseth may continue to actively manage his real estate investments.
Stenseth may participate in other businesses as a passive investor, provided
that (a) Stenseth shall not actively participate in the operation or management
of such businesses, and (b) Stenseth shall not, without the prior written
approval of the Bank of Vancouver, make or maintain any investment in a business
with which the Bank of Vancouver and/or West Coast has an existing competitive
or commercial relationship.

         5. Salary. Initially, Stenseth shall receive a salary of Eighty-Five
Thousand Dollars ($85,000) per year, which shall be paid monthly in accordance

immediately prior to the anniversary date of this Agreement reduced by all
expenses of the Bank of Vancouver for such period other than accrued federal
income taxes arising from such earnings, as determined for financial statement
purposes by the auditors of the Bank of Vancouver utilizing generally accepted

            (a) Vacation and Holidays. Stenseth will accrue eight (8) weeks of

group life insurance, health and accident insurance plans, profit sharing and
pension plans and in such other employee fringe benefit programs as the Bank of
Vancouver may have in effect from time to time for its employees, in accordance
with any policies adopted by the Board of Directors of the Bank of Vancouver
with regard thereto. It is understood that the Bank of Vancouver, by reason of
this Agreement, has not obligated itself to make any particular benefits
available to its employees.

            (c) Business Expenses. The Bank of Vancouver shall reimburse
Stenseth for ordinary and necessary expenses (including, without limitation,
travel, entertainment, and similar expenses) incurred in performing and
promoting the business of the Bank of Vancouver. Stenseth shall present from
time to time itemized accounts of any such expenses, subject to any limits of
the Bank of Vancouver policy and the rules and regulations of the Internal
Revenue Service.

            (d) ESI-Agreement. This Agreement is not intended to modify any

         9. Termination of Employment.

            (a) Termination By Bank of Vancouver for Cause. In the event that
the Bank of Vancouver terminates Stenseth's employment prior to the termination
of this Agreement for Cause, as defined in Section 9(e), the Bank of Vancouver
shall pay Stenseth such salary earned and expenses reimbursable under this
Agreement incurred through such termination date. In such case, Stenseth will
have no right to receive compensation or other benefits for any period after
termination under this Section 9(a).

            (b) Other Termination By Bank of Vancouver. In the event that the
Bank of Vancouver terminates Stenseth's employment prior to the termination of
this Agreement without Cause, or Stenseth terminates for Good Reason (as defined
in Section 9(f), the Bank of Vancouver shall pay Stenseth the salary and other
benefits to which Stenseth would be entitled but for such termination.

            (c) Death or Disability. This Agreement shall terminate in the event
that Stenseth dies or is unable to perform his duties and obligations under this
Agreement for a period of ninety (90) days as a result of a physical or mental
disability arising at any time during

                                      - 3 -
<PAGE>   4
the term hereof, unless with reasonable accommodation Stenseth could continue to
perform his duties under this Agreement, which accommodations shall not require
the Bank of Vancouver to expend any funds. In the event of any termination under
this Section 9(c), Stenseth or his estate shall be entitled to receive all
compensation and benefits earned through the date of termination, and such
additional compensation as would be payable to Stenseth upon termination under
Section 9(a).

            (d) Return of Bank Property. At the time Stenseth ceases, for any
reason, to be employed by the Bank of Vancouver, Stenseth agrees that he will
return to the Bank of Vancouver all keys, pass cards, identification cards and
any other property of the Bank of Vancouver and/or West Coast. At the same time,
he also will return to the Bank of Vancouver all originals and copies (whether
in hard copy, electronic or other form) of any documents, drawings, notes,
memoranda, designs, devices, diskettes, tapes, manuals, and specifications which
constitute proprietary information or material of the Bank of Vancouver and/or
West Coast. The obligations in this paragraph include the return of documents
and other materials which may be in his desk at work, in his car, in place of
residence, or in any other location under his control.

            (e) Cause. "Cause" shall mean only any one or more of the following:

                  (i) Willful misfeasance or gross negligence in the performance
         of Stenseth's duties,

                  (ii) Conviction of a crime in connection with such duties; or

                  (iii) Conduct demonstrably and significantly harmful to the
         Bank of Vancouver as determined in the reasonable discretion of the
         Board of Directors of the Bank of Vancouver.

                  (iv) Permanent disability, which shall mean a physical or
         mental impairment which renders Stenseth incapable of substantially
         performing the duties required under this Agreement, and which is
         expected to continue rendering Stenseth so incapable for the reasonably
         foreseeable future.

            (f) Good Reason. "Good Reason" shall mean only any one or more of
the following:

                  (i) Any reduction of Stenseth's salary or any reduction or
         elimination of any compensation or benefit plan benefitting Stenseth,
         which reduction or elimination is not of general application to
         substantially all employees of the Bank of Vancouver or such employees
         of any successor entity or of any entity in control of the Bank of
         Vancouver;

                  (ii) The assignment to Stenseth of any authority or duties
         materially inconsistent with Stenseth's position as of the date of this
         Agreement; or

<PAGE>   5
                  (iii) A relocation or transfer of Stenseth's place of
         employment that would require Stenseth to commute more than twenty-five
         (25) miles each way from Stenseth's principal residence.

         10. Confidentiality. Stenseth shall not, during the term of this
Agreement or thereafter, use for his own purposes or disclose to any other
person or entity any confidential business information concerning the Bank of
Vancouver and/or West Coast or its business operations, except as may be
consistent with his duties hereunder. Confidential business information shall be
interpreted to have the same meaning as a trade secret under the Uniform Trade
Secrets Act as adopted in Washington (RCW 19.108), and shall include, without
limitation, various confidential information concerning all aspects of current
and future operations, nonpublic information on investment management practices,
marketing plans, pricing structure and technology of either the Bank of
Vancouver and/or West Coast. Stenseth further agrees to treat the terms of this
Agreement as confidential, except as may be required to implement its terms or
to the extent disclosure is required by law or order of a court of competent
jurisdiction.

         11. Noncompetition. During the term of this Agreement and the term of
any extensions or renewals hereof and for a period equal to the lesser of (i)
two (2) years after Stenseth's employment with the Bank of Vancouver and/or West
Coast has terminated or (ii) three years from Closing of the Merger, Stenseth
agrees that Stenseth shall not, directly or indirectly, as a shareholder,
director, officer, employee, partner, agent, consultant, lessor, creditor or
otherwise:

             (a) provide management, supervisory or other similar services to
any person or entity engaged in any business in Washington or Oregon which is
competitive with the business of the Bank of Vancouver and/or West Coast as
conducted during the term of this Agreement or as conducted as of the date of
termination of employment; or

             (b) persuade or entice, or attempt to persuade or entice, any
employee of the Bank of Vancouver and/or West Coast to terminate his or her
employment with the Bank of Vancouver and/or West Coast, or persuade or entice
or attempt to persuade or entice, any person or entity to terminate, cancel,
rescind or revoke its business or contractual relationships with the Bank of
Vancouver and/or West Coast.

         12. Enforcement.

             (a) The Bank of Vancouver and Stenseth stipulate and agree that, in
light of all of the facts and circumstances of the relationship between Stenseth
and the Bank of Vancouver, the agreements referred to in Sections 10 and 11
(including but not limited to the scope of the restricted activities and the
duration and geographic extent of such restrictions) are fair and reasonably
necessary for the protection of the Bank of Vancouver's and/or West Coast's
confidential information, goodwill and other protectable interests. In the event
a court of competent jurisdiction should decline to enforce any of those
covenants and agreements, Stenseth and the Bank of Vancouver agree that such
provisions shall be deemed to be reformed to restrict Stenseth's use of
confidential information and Stenseth's ability to compete

                                      - 5 -
<PAGE>   6
with the Bank of Vancouver and/or West Coast to the maximum extent, in time,
scope of activities, and geography, that the court shall find enforceable.

             (b) Stenseth acknowledges that the Bank of Vancouver and/or West
Coast will suffer immediate and irreparable harm that will not be compensable by
damages alone in the event Stenseth repudiates or breaches any of the provisions
of Sections 10 or 11 or threatens or attempts to do so. In the event of any such
breach or any threatened or attempted breach, Stenseth agrees that the Bank of
Vancouver, in addition to and not in limitation of any other rights, remedies or
damages available to it at law or in equity, shall be entitled to obtain
temporary, preliminary and permanent injunctions in order to prevent or restrain
any such breach, and the Bank of Vancouver shall not be required to post a bond
as a condition for the granting of such relief.

         13. Indemnification by Stenseth. Stenseth agrees to indemnify the Bank
of Vancouver and hold it harmless from and against any loss, claim or liability,
including attorney's fees or other legal expenses incurred in the defense
thereof, incurred by the Bank of Vancouver as a result of any breach by Stenseth
of Sections 10 or 11 of this Agreement.

         14. Covenants. Stenseth specifically acknowledges the receipt of
adequate consideration for the covenants contained in Sections 10 and 11 of this
Agreement and that the Bank of Vancouver is entitled to require compliance with
them. These covenants shall survive termination of this Agreement. Stenseth
represents and agrees that in the event of termination of employment, whether
voluntarily or involuntarily, Stenseth has experience and capabilities which
enable Stenseth to obtain employment in areas which do not violate this
Agreement, and that the enforcement of a remedy by way of injunction will not
prevent Stenseth from earning a livelihood.

         15. Arbitration and Governing Law. Any controversy or claim arising out
of or relating to this Agreement or the breach thereof shall be settled by
arbitration in accordance with the rules of Judicial Arbitration and Mediation
Services, Inc. ("JAMS") or, if JAMS is unable or unwilling to act for any
reason, the commercial arbitration rules of the American Arbitration
Association. Such controversy or claim shall be resolved as soon as practicable
by a single arbitrator to be agreed upon by the parties or, in the absence of
agreement within ten days following the date on which a single arbitrator is
proposed, by a panel of three arbitrators selected in accordance with such
rules. Selection of the arbitrator(s) and all procedural aspects of the
arbitration shall be pursuant to said rules, and judgments upon the award
rendered in such arbitration may be entered in any court having jurisdiction
thereof. All proceedings shall be held at a place designated by the
arbitrator(s) in Seattle, Washington, and the arbitrator(s), in rendering a
decision as to any state law claims, shall apply the laws of the State of
Washington. All expenses of arbitration, including without limitation
arbitration fees, costs and reasonable attorneys' fees, shall be awarded by the
arbitrator(s) in favor of such party as the arbitrator(s) shall determine to be
the prevailing party in such arbitration. Notwithstanding the foregoing, in the
event of any violation by Stenseth of Section 10 and/or 11 of this Agreement,
the Bank of Vancouver shall have the right to initiate the court proceeding
described in Section 12, in lieu of an arbitration proceeding under this
subparagraph.

                        DIRECTOR NONCOMPETITION AGREEMENT

         This Agreement, dated as of February 15, 1996, is between WEST COAST
BANCORP ("WCB"), HB ACQUISITION CORPORATION ("HB"), VANCOUVER BANCORP ("VB"),
and the undersigned, each of whom is a Director ("Director") of VB and the Bank
of Vancouver ("Bank").

                                    RECITALS

A.       WCB, HB and VB have entered into a Plan and Agreement of Reorganization
         and Merger ("Merger Agreement"), dated as of February 15, 1996, under
         which VB will merge with and into HB.

B.       The obligations of WCB and HB to consummate the transactions
         contemplated by the Merger Agreement are conditioned on their receipt
         of noncompetition agreements from all directors of VB and the Bank.

C.       WCB, HB, VB and Director believe that the future success and
         profitability of the Bank require that existing directors of VB and the
         Bank be available to continue to serve as directors of the Bank and not
         be affiliated in any substantial way with a Competing Business for a
         reasonable period of time after Closing.

                                    AGREEMENT

         In consideration of WCB's and HB's performance under the Merger
Agreement, Director agrees as follows:

1.       DEFINITIONS. Defined terms used but not expressly defined in this
         Director Noncompetition Agreement ("Director Agreement"), have the
         meaning assigned to those terms in the Merger Agreement. For purposes
         of this "Director Agreement" the following definitions also apply:

         (a)      Competing Business. "Competing Business" means any financial
                  institution or trust company that competes within the Covered
                  Area with WCB, HB, VB, the Bank or their subsidiaries or
                  affiliates.

         (b)      Covered Area. Clackamas, Lincoln, Marion, Multnomah, and
                  Washington Counties in Oregon State and Clark County in
                  Washington State.

         (c)      Term. The Term of this Director Agreement is the lesser of:
                  (1) two years after the Director's service as a director of
                  VB, the Bank, WCB, or any affiliate of WCB is terminated or
                  (2) three years from Closing.

2.       AVAILABILITY. Director will be available to serve, at WCB's request, as
         a director of the Bank for a period of at least one year after Closing.

                                       -1-
<PAGE>   2
3.       PARTICIPATION IN COMPETING BUSINESS. Except as provided in Section 6,
         during the Term of this Director Agreement, Director will not become
         involved, directly or indirectly, as a shareholder, member, partner,
         director, officer, manager, consultant, agent or representative of a
         Competing Business.

4.       CONFIDENTIAL INFORMATION. During and after the Term of this Director
         Agreement, Director will not disclose any confidential information of
         WCB, HB, VB, the Bank or their subsidiaries or affiliates obtained by
         the Director while serving as a director the Bank.

5.       EMPLOYMENT OUTSIDE COVERED AREA. Nothing in this Director
         Noncompetition Agreement prevents the Director from accepting
         employment outside the Covered Area from a Competing Business, if,
         during the Term, the Director: (a) will not act as an employee or other
         representative or agent of the Competing Business within the Covered
         Area and (b) will have no responsibilities for the Competing Business'
         operations within the Covered Area.

6.       PASSIVE INTEREST. Nothing in this Director Agreement prevents the
         Director from owning 2% or less of any class of security of a Competing
         Business.

7.       REMEDIES. Any breach of this Agreement by Director entitles WCB, HB,
         and VB, together with their successors and assigns, to injunctive
         relief and/or specific performance, as well as to any other legal or
         equitable remedies they may be entitled to.

8.       GOVERNING LAW AND ENFORCEABILITY. This Director Agreement is governed
         by Washington State law. If any court determines that the restrictions
         set forth in this Director Agreement are unenforceable, the maximum
         restrictions, term, scope or geographical area that is enforceable will
         be substituted in place of the unenforceable provisions.

9.       COUNTERPARTS. The parties may execute this Agreement in one or more
         counterparts. All the counterparts will be construed together and will
         constitute one Agreement.
