ITEM 5 - OTHER EVENTS

         On February 15, 1996, West Coast Bancorp, Lake Oswego, Oregon ("WCB")
entered into a definitive agreement (the "Merger Agreement") with Vancouver
Bancorp, Vancouver, Washington ("VB") and HB Acquisition Corporation, (a wholly
owned subsidiary of Bancorp formed under the laws of the State of Washington to
facilitate the acquisition).  Under the terms of the Merger Agreement, VB will
be merged with Acquisition Corp.

         The Merger Agreement provides that VB's common stock will be exchanged
for shares of WCB common stock pursuant to a pricing mechanism.  The aggregate
value of the consideration is approximately $11.6 million, subject to
adjustments.

         In connection with the Merger Agreement, WCB and VB entered into a
Stock Option Agreement dated February 15, 1996 ("Option Agreement") whereby VB
granted WCB an option to purchase 19.9% of VB's common stock at a price equal
to the then market value of VB's common stock, under the circumstances, terms
and conditions set forth in the Option Agreement.  The Option Agreement is
exercisable upon the occurrence of certain transactions, including the
acquisition by any person or group of control or beneficial ownership of 25% or
more of VB's common stock.

         Consummation of the acquisition is subject to several conditions,
including receipt of applicable regulatory approval and approval by VB's
shareholders.  For information regarding the terms of the proposed transaction,
reference is made to the Merger Agreement, Option Agreement and the press
release dated January 15, 1996, which are attached hereto as Exhibits 2, 10 and
99, respectively, and incorporated herein by reference.

         officers of HB will become the directors and officers of the Combined
         Corporation.  On the Effective Date, HB's shares then issued and

                 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.

                 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>   17
                 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.

                          (c)     Lost, Stolen, and Destroyed Certificates.  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>   19
         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

         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:

                 (a)      each condition precedent set forth in Section 5 has
                          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.

                                   SECTION 3.
                         REPRESENTATIONS AND WARRANTIES

         3.1.    REPRESENTATIONS AND WARRANTIES OF WCB, HB, AND VB.  Subject to
         Subsection 3.3 and except as expressly set  forth in Schedule 1, WCB
         and HB each represent and warrant to VB, and VB represents and
         warrants to WCB and HB, the following:

                                  that date to provide for estimable and
                                  probable losses, net of recoveries relating
                                  to loans previously charged off, inherent in
                                  its loan portfolio.

                 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

                 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.

                          (f)     Under each of its and its ERISA Affiliates'
                                  Pension Plans that is a single-employer 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 year that reasonably could be expected
                                  to change such conclusion.  There would be no
                                  withdrawal liability of it and its
                                  subsidiaries under each Plan that is a
                                  multi-employer plan to which it, its
                                  subsidiaries or its ERISA Affiliates has
                                  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.

                          (g)     Except as disclosed in its Financial
                                  Statements, neither it nor its subsidiaries
                                  have any obligations for retiree health and
                                  life benefits.

                          (h)     No restrictions exist on the rights of it or
                                  its subsidiaries to amend or terminate any
                                  Plan without incurring liability under the
                                  Plan in addition to normal liabilities for
                                  benefits.

                          (i)     Except as disclosed in its Financial
                                  Statements or as provided in a schedule to
                                  this Agreement, the transactions contemplated
                                  by this Agreement and the Stock Plans will
                                  not result in: (1) vesting, acceleration, or
                                  increase of any amounts payable under any
                                  Compensation Plan, (2) any material increase
                                  in benefits under any Compensation Plan or
                                  (3) payment of any severance or similar
                                  compensation under any Compensation Plan.

                          (j)     The Bank's obligations under the Executive
                                  Supplemental Income ("ESI") Plan will not at
                                  any time exceed the value, as reflected on
                                  the Bank's books (reported consistent with
                                  GAAP), of insurance policies owned by the
                                  Bank on the lives of the officers covered by
                                  the ESI Plan.

                                  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.

                                  contracts and documents available at all

                                  accountants and other representatives.  These
                                  items will be open for inspection, audit and
                                  direct verification of: (1) loan or deposit
                                  balances, (2) collateral receipts and (3) any
                                  other transactions or documentation WCB may

                                  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
                                  parties involved in the preparation or review
                                  of the VB/Bank Financial Statements or
                                  Subsequent VB/Bank Financial Statements to

                                  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 and will
                 not, and will not allow the Bank to, do any of the following:

                          (a)     effect any stock split or other
                                  recapitalization with respect to VB Common

                                  granted before the date of this Agreement);

                          (b)     declare or pay any dividend, or make any
                                  other distribution, either directly or

                                  to reflect changes in prevailing interest

                                  $5,000;

                          (e)     acquire an ownership interest or a leasehold

                          (g)     enter into any other transaction or make any
                                  expenditure other than in the ordinary and
                                  usual course of its business or as required
                                  by this Agreement, except for expenses
                                  reasonably related to completion of the
                                  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

                 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.

                                  with GAAP (before any adjustments not
                                  reflected in VB's Financial Statements as of
                                  December 31, 1995, required by Federal

                                  (collectively, "Core Deposits"), will not be
                                  less than 95% of the daily average Core
                                  Deposits of the Bank for the 90-day period
                                  ending two days before Closing;

                          (c)     the Bank's allowance for possible loan and
                                  lease losses (1) at December 31, 1995, and at
                                  Closing will be adequate to absorb the Bank's
                                  anticipated loan and lease losses (taking
                                  into account any recommendations made by VB's
                                  certified public accountants) and (2) at

                          (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.

                 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

                 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-

         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>   57
                          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>   58
                                  (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 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

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

<PAGE>   61
                 (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.

         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.

         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.

                             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

                 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>   4
                 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,
                 to the effect that such legend is not required for purposes of
                 the 1933 Act; and (b) the reference to the provisions to this
                 Agreement in the above legend shall be removed by delivery of
                 substitute certificate(s) without such reference if the shares
                 have been sold or transferred in compliance with the provisions
                 of this Agreement and under circumstances that do not require
                 the retention of such reference. In addition, such certificates
                 shall bear any other legend as may be required by law.

         2.5     Delivery. Upon the giving by the Holder to VB of the
                 written notice of exercise of the Option provided for under
                 Subsection 2.2 and the tender of the applicable purchase price
                 in immediately available funds, the Holder shall be deemed to
                 be the holder of record of the shares of Common Stock issuable
                 upon such exercise, notwithstanding that the stock transfer
                 books of VB shall then be closed or that certificates
                 representing such shares of Common Stock shall not then be
                 actually delivered to the Holder. VB shall pay all expenses,
                 and any and all United States federal, state and local taxes
                 and other charges that may be payable in connection with the
                 preparation, issue and delivery of stock certificates

                          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

                          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.

                 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-

         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>   9
                 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>   10
         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 3.4.a without VB's
                 approval, recommendation or consent, promptly request that VB


                                      -10-
<PAGE>   12
                 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>   13
                 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.

<PAGE>   14
                 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>   15
                 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-
<PAGE>   16
                 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); 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>   17
         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

         Sections and Subsections refer to Sections and Subsections of this
         Agreement.

         IN WITNESS WHEREOF, each of the parties has caused this Agreement to be

PRESS RELEASE
FOR IMMEDIATE RELEASE

                WEST COAST BANCORP ANNOUNCES DEFINITIVE AGREEMENT
                          TO ACQUIRE VANCOUVER BANCORP

Lake Oswego, Oregon - February 15, 1996 - West Coast Bancorp (NASDAQ: WCBO)
today announced the signing of a Definitive Agreement to acquire Vancouver
Bancorp of Vancouver, Washington. This move is designed to facilitate the
natural expansion of a successful $517 million Oregon based community banking
organization into the economically strong greater Portland Metropolitan area.

Vancouver Bancorp is the parent company of Bank of Vancouver, a rapidly growing
commercial bank located in downtown Vancouver. On December 31, 1995 the six and
one-half year old bank subsidiary had assets of $78.9 million and loans of $61.0
million representing 77.3 percent of total assets. The merger will enable Bank
of Vancouver to broaden their products and services and expand their markets in
the rapidly developing Clark County area of southwestern Washington.

In the merger, Vancouver Bancorp shareholders will receive stock of West Coast
Bancorp worth $11.6 million. Based on the terms of the merger agreement, the
exchange ratio is subject to the average price of West Coast Bancorp stock over
a ten day period prior to the closing of the merger. If West Coast Bancorp stock
is at or above $18.70 per share at closing, the exchange ratio will be 3.5808.
Should West Coast Bancorp stock close at $15.30 per share, the exchange ratio
would be 4.3765. The merger is expected to be accounted for as a pooling of
interests.

In addition, Vancouver Bancorp has granted to West Coast Bancorp an option to
purchase up to 19.9% of its common stock under certain circumstances.

"This is an extremely attractive opportunity that is consistent with our
strategic plan to diversify and expand our community banking activities into the
vibrant Southwest Washington area. We believe this move should enhance the
long-term profitability and shareholder value of our company," said West Coast
Bancorp Co-President and CEO, Rodney B. Tibbatts.

Victor L. Bartruff, Co-President and CEO of West Coast Bancorp added, "The Bank
of Vancouver in its brief years of existence has shown solid growth with a
particular orientation towards the small business market, which is consistent
with our business banking focus in the Portland Metropolitan area. In addition,
this transaction is expected to increase our earnings per share in 1997."

Lee S. Stenseth, President of Vancouver Bancorp and The Bank of Vancouver
commented, "The combination of our two successful companies will clearly benefit
our customers, employees and shareholders. Also, our bank will continue to serve
our customers and the greater Vancouver area under The Bank of Vancouver name,
served by our dedicated local Board of Directors and management."

Vancouver Bancorp has a history of strong growth in deposits, loans, assets and
earnings. During 1995, Vancouver Bancorp earned $891 thousand representing a
1.26 percent return on average assets and a 17.2 percent return on average
equity. On December 31, 1995, Vancouver Bancorp had equity of $5.8 million,
nonperforming assets of only $110 thousand or .15 percent of assets and a loan
loss reserve of $848 thousand or 1.4 percent of outstanding loans.

West Coast Bancorp recently reported a solid 1995 year of performance, recording
new highs in total assets, deposits, loans and earnings. Consolidated net income
of $7,359,000 or $1.53 per share represented a 1.53 percent return on average
assets and a 15.50 percent return on average equity. Asset quality is high with
nonperforming assets of only $591,000 representing 0.11 percent of total assets.
The loan loss reserve of $4,721,000 equaled 1.39 percent of outstanding loans at
year-end 1995.

West Coast Bancorp, Oregon's only multi-bank holding company, is the parent
company of The Bank of Newport - Newport, The Commercial Bank - Salem, Valley
Commercial Bank - Forest Grove and operates its trust division as West Coast
Trust. The company commenced operations on March 1, 1995 under the West Coast
Bancorp name utilizing the Commercial Bancorp charter. The combined entity will
have 29 offices, assets exceeding $600 million and will operate in eight
counties throughout Western Oregon and Southwest Washington.
