         Item 5.   Other Events.

                   On February 11, 1996, California Bancshares, Inc., a
         Delaware corporation (the "Company"), entered into an Agreement
         and Plan of Merger (the "Merger Agreement") with U.S. Bancorp,
         an Oregon corporation ("Bancorp"), pursuant to which the Com-
         pany will be merged with and into Bancorp (the "Merger").  As a
         result of the Merger, each outstanding share of the Company's
         common stock, par value $2.50 per share ("Company Common
         Stock"), will be converted into 0.95 shares of Bancorp Common
         Stock, par value $5.00 per share ("Bancorp Common Stock").  The
         Merger is conditioned upon, among other things, approval by
         shareholders of the Company, and upon certain regulatory ap-
         provals.  The Merger is expected to be completed during the
         second half of 1996.  The Merger Agreement is attached as Ex-
         hibit 2 hereto and its terms are incorporated herein by refer-
         ence.

                   As a condition to entering into the Merger Agreement,
         on February 12, 1996, Bancorp and the Company entered into a
         Stock Option Agreement between the Company, as issuer, and Ban-
         corp, as grantee (the "Stock Option Agreement"), pursuant to
         which the Company granted to Bancorp the right, upon the terms
         and subject to the conditions set forth therein, to purchase up
         to 19.9 percent of the outstanding shares of Company Common
         Stock at a price of $25.75 per share.  The Stock Option Agree-
         ment is attached as Exhibit 3 hereto, and its terms are incor-
         porated herein by reference.

               U.S. BANCORP TO ACQUIRE CALIFORNIA BANCSHARES, INC.

                     MOVE ENHANCES U.S. BANK OF CALIFORNIA'S
                           COMMERCIAL BANKING OPERATION

         PORTLAND, ORE. & SAN RAMON, CALIF -- U.S. Bancorp (Nasdaq:  USBC)

         and California Bancshares, Inc. (Nasdaq:  CABI) today announced the

         signing of a definitive agreement for U.S. Bancorp to acquire Cali-

         fornia Bancshares, the holding company for a multi-bank, 36-branch

         commercial banking operation serving the east San Francisco Bay

         Area and the Central Valley of Northern California.


                   Under terms of the agreement, which is subject to

         approval by regulators and California Bancshares shareholders,

         California Bancshares will be merged into U.S. Bancorp, and

         each share of California Bancshares common stock will be con-

         verted into .95 shares of U.S. Bancorp common stock.  The total

         value of the transaction is approximately $327 million, or

         $32.53 for each share of California Bancshares' common stock,

         based on the U.S. Bancorp stock closing price of $34.25 on Feb-

         ruary 9, 1996.  This transaction will be accounted for as a

         pooling of interest.


                   In connection with the agreement, California Banc-

         shares granted U.S. Bancorp an option to acquire 19.9 percent<PAGE>





         of California Bancshares stock, which could become exercisable

         under certain circumstances,


                   "The addition of this highly respected company to our

         U.S. Bank of California franchise provides entry into densely

         populated, growing markets that we have long had an interest

         in," said U.S. Bancorp Chairman and CEO, Gerry Cameron.  Be-

         sides building our California branch presence, this acquisition

         gives us an opportunity to leverage one of U.S. Bancorp's key

         strengths, our ability to attract and effectively serve a wide

         range of business customers.


                   "Under the direction of Pete Sinclair, we've made

         great progress in building a successful commercial enterprise

         in California," noted Cameron.  "The addition of California

         Bancshares will greatly accelerate our growth and performance

         in California."


                   California Bancshares is a $1.6 billion bank holding

         company with 10 commercial bank subsidiaries operating in com-

         munities throughout Alameda, Contra Costra, Stanislaus and San

         Joaquin counties, and one branch in northern Santa Clara

         county.  This highly profitable and well-capitalized organiza-

         tion was formed in 1991 by a merger between Northern California

         Community Bancorp and Mission Valley Bancorp, and has grown

         through subsequent acquisitions to its current size.


                   "We are delighted to enter into this agreement," said

         California Bancshares president and CEO, Joe Colmery.  "We feel 



                                       -2-<PAGE>





         this affiliation will give us a significant competitive advan-

         tage and will clearly benefit our shareholders and customers.

         We will now be able to compete more effectively because we can

         offer both our business and retail customers a much wider array

         of products and services, greater banking convenience through a

         variety of traditional and technological avenues, and the fi-

         nancial resources of a $32 billion super-regional bank.


                   "Our business mix and culture mesh very well with

         U.S. Bancorp," said Colmery.  "We feel our employees will ben-

         efit from the increased opportunities presented in a much larg-

         er organization."


                   California Bancshares complements the current U.S.

         Bank of California operation which was formed by the acquisi-

         tion of eight companies in the late 1980s and early 1990s.

         This addition will increase U.S. Bank of California's operation

         of 57 branches in 22 northern counties to 93 branches in 27

         counties.  It will also increase U.S. Bank of California's to-

         tal deposits by over 80 percent.


                   "We see opportunities to enhance revenues through the

         considerable number of additional products and services U.S.

         Bank can make available to California Bancshares business and

         retail customers, as well as the substantial number of new cus-

         tomers we can attract," said Pete Sinclair, U.S. Bank of Cali-

         fornia president and CEO.  "There are tremendous corporate and

         commercial real estate development opportunities, as well as 




                                       -3-<PAGE>





         trust and investment opportunities in this new territory.  We

         are very excited to be in these markets.


                   "One of the most attractive features of this transac-

         tion is the addition of highly-skilled employees in key markets

         not already served by U.S. Bank of California," Sinclair added.

         "We are committed to making our neighborhoods better places in

         which to live, work and do business, and I am confident that

         these employees will help U.S. Bank of California to continue

         with its strong record of community reinvestment."


                   Because there is no overlap in branches, Sinclair

         said he expects the majority of California Bancshares branch

         employees to continue with the bank in the future.  "Customers

         can expect to deal with familiar faces," he noted.  Cost sav-

         ings will be created through the consolidations of California

         Bancshares administrative and back office operations.  The num-

         ber of positions to be eliminated due to the acquisition has

         not yet been determined.


                   The acquisition is expected to be completed during

         the second half of 1996; conversion of bank operations is slat-

         ed for the first quarter 1997.


                   California Bancshares is a $1.6 billion bank holding

         company which includes the following banks:  Alameda First Na-

         tional, Community First National, Modesto Banking Co., Com-

         mercial Bank of Fremont, Lamorinda National Bank, Centennial 





                                       -4-<PAGE>





         Bank, Bank of San Ramon Valley, Westside Bank, Concord Commer-

         cial Bank and Bank of Milpitas.


                   Northwest-based U.S. Bancorp is one of the 30 largest

         bank holding companies in the nation, with assets of approxi-

         mately $32 billion.  The company provides comprehensive finan-

         cial products and services to consumers, businesses and corpo-

         rations, and to individual and institutional investors through

         subsidiary banks in six western states.

                           AGREEMENT AND PLAN OF MERGER

                   AGREEMENT AND PLAN OF MERGER, dated as of February
         11, 1996, by and between U.S. BANCORP, an Oregon corporation
         ("Bancorp"), and CALIFORNIA BANCSHARES, INC., a Delaware corpo-
         ration ("CBI").

                   WHEREAS, the Boards of Directors of Bancorp and CBI
         have determined that it is in the best interests of their re-
         spective companies and their shareholders to consummate the
         merger provided for herein in which CBI will, subject to the
         terms and conditions set forth herein, merge (the "Merger")
         with and into Bancorp, so that Bancorp is the surviving corpo-
         ration in the Merger;

                   WHEREAS as a condition to, and on the day immediately
         after the date of execution of, this Agreement, Bancorp and CBI
         are entering into a CBI Stock Option Agreement (the "CBI Option
         Agreement"); and

                   WHEREAS, the parties desire to make certain represen-
         tations, warranties and agreements in connection with the
         Merger and also to prescribe certain conditions to the Merger;

                   NOW, THEREFORE, in consideration of the mutual cov-
         enants, representations, warranties and agreements contained
         herein, and intending to be legally bound hereby, the parties
         agree as follows:


                                    ARTICLE I
                                    THE MERGER

                   1.1.  The Merger.  Subject to the terms and condi-
         tions of this Agreement, CBI shall merge with and into Bancorp
         at the Effective Time (as defined in Section 1.2 hereof) in
         accordance with the Oregon Business Corporation Act (the
         "OBCA") and the Delaware General Corporation Law (the "DGCL").
         Bancorp shall be the surviving corporation (hereinafter some-
         times called the "Surviving Corporation") in the Merger, and
         shall continue its corporate existence under the laws of the
         State of Oregon.  Upon consummation of the Merger, the separate
         corporate existence of CBI shall terminate.

                   1.2  Effective Time.  The Merger shall become effec-
         tive as set forth in articles of merger (the "Articles of
         Merger") which shall be filed with the Secretary of State of
         the State of Oregon (the "Oregon Secretary") and a certificate
         of merger (the "Certificate of Merger") which shall be filed
         with the Secretary of State of the state of Delaware (the<PAGE>







         "Delaware Secretary"), in each case, on the Closing Date (as
         defined in Section 9.1 hereof).  The date and time when the
         Merger becomes effective, as set forth in the Articles of
         Merger and the Certificate of Merger, is herein referred to as
         the "Effective Time."

                   1.3  Effects of the Merger.  At and after the Effec-
         tive Time, the Merger shall have the effects set forth in Sec-
         tion 60.497 of the OBCA and Sections 259 and 261 of the DGCL.

                   1.4  Conversion of CBI Common Stock.  At the Effec-
         tive Time, subject to Section 2.2(e) hereof, by virtue of the
         Merger, and without any action on the part of Bancorp, CBI or
         the holder of any share of the common stock, par value $2.50
         per share, of CBI ("CBI Common Stock"), each share of CBI Com-
         mon Stock issued and outstanding immediately prior to the Ef-
         fective Time (other than shares of CBI Common Stock held (x) in
         CBI's treasury or (y) directly or indirectly by Bancorp or CBI
         or any of their respective Subsidiaries (as defined below) (ex-
         cept for Trust Account Shares and DPC Shares, as such terms are
         defined below)) shall be converted into the right to receive
         .95 shares (the "Exchange Ratio") of common stock, $5.00 par
         value per share, of Bancorp ("Bancorp Common Stock").

                   All of the shares of CBI Common Stock converted into
         Bancorp Common Stock pursuant to this Article I shall no longer
         be outstanding and shall automatically be canceled and shall
         cease to exist as of the Effective Time, and each certificate
         (each a "CBI Certificate") previously representing any such
         shares of CBI Common Stock shall thereafter represent the right
         to receive (i) a certificate representing the number of whole
         shares of Bancorp Common Stock and (ii) cash in lieu of frac-
         tional shares into which the shares of CBI Common Stock repre-
         sented by such CBI Certificate have been converted pursuant to
         this Section 1.4 and Section 2.2(e) hereof.  CBI Certificates
         previously representing shares of CBI Common Stock shall be
         exchanged for certificates representing whole shares of Bancorp
         Common Stock and cash in lieu of fractional shares issued in
         consideration therefor upon the surrender of such CBI Certifi-
         cates in accordance with Section 2.2 hereof, without any inter-
         est thereon.  If prior to the Effective Time (or as of a record
         date prior to the Effective Time) the outstanding shares of
         Bancorp Common Stock shall have been increased, decreased,
         changed into or exchanged for a different number or kind of
         shares of securities as a result of a reorganization, recapi-
         talization, reclassification, stock dividend, stock split, re-
         verse stock split, or other similar change in Bancorp's capi-
         talization, then an appropriate and proportionate adjustment
         shall be made to the Exchange Ratio.




                                       -2-<PAGE>







                   At the Effective Time, all shares of CBI Common Stock
         that are owned by CBI as treasury stock and all shares of CBI
         Common Stock that are owned directly or indirectly by Bancorp
         or CBI or any of their respective Subsidiaries (other than
         shares of CBI Common Stock held directly or indirectly in trust
         accounts, managed accounts and the like or otherwise held in a
         fiduciary capacity that are beneficially owned by third parties
         (any such shares, and shares of Bancorp Common Stock that are
         similarly held, whether held directly or indirectly by Bancorp
         or CBI, as the case may be, being referred to herein as "Trust
         Account Shares") and other than any shares of CBI Common Stock
         held by Bancorp or CBI or any of their respective Subsidiaries
         in respect of a debt previously contracted (any such shares of
         CBI Common Stock, and shares of Bancorp Common Stock that are
         similarly held, whether held directly or indirectly by Bancorp
         or CBI or any of their respective Subsidiaries, being referred
         to herein as "DPC Shares")) shall be canceled and shall cease
         to exist and no stock of Bancorp or other consideration shall
         be delivered in exchange therefor.  All shares of Bancorp Com-
         mon Stock that are owned by CBI or any of its Subsidiaries
         (other than Trust Account Shares and DPC Shares) shall become
         authorized but unissued stock of Bancorp.

                   1.5.  Bancorp Common Stock; Bancorp Preferred Stock.
         At and after the Effective Time, each share of Bancorp Common
         Stock and each share of Series A preferred stock, no par value,
         of Bancorp issued and outstanding immediately prior to the
         Closing Date shall remain an issued and outstanding share of
         common stock or preferred stock, as the case may be, of the
         Surviving Corporation and shall not be affected by the Merger.

                   1.6.  Options.  Outstanding options to purchase CBI
         Common Stock shall be exchanged at the Effective Time as pro-
         vided in Section 6.7(c).

                   1.7.  Articles of Incorporation.  At the Effective
         Time, the Articles of Incorporation of Bancorp, as in effect
         immediately prior to the Effective Time, shall be the Articles
         of Incorporation of the Surviving Corporation.

                   1.8.  Bylaws.  At the Effective Time, the Bylaws of
         Bancorp, as in effect immediately prior to the Effective Time,
         shall be the Bylaws of the Surviving Corporation until thereaf-
         ter amended in accordance with applicable law.

                   1.9.  Tax Consequences.  It is intended that the
         Merger shall constitute a reorganization within the meaning of
         Section 368(a) of the Code and that this Agreement shall con-
         stitute a "plan of reorganization" for the purposes of Section
         368 of the Code.

                   1.10.  Board of Directors.  From and after the Effec-
         tive Time, the Board of Directors of the Surviving Corporation
         shall consist of members of the Board of Directors of Bancorp
         as constituted immediately prior to the Effective Time.


                                    ARTICLE II
                                EXCHANGE OF SHARES

                   2.1  Bancorp to Make Shares Available.  At or prior
         to the Effective Time, Bancorp shall deposit or shall cause to
         be deposited, with a bank or trust company selected by Bancorp
         and reasonably acceptable to CBI (which may be a Subsidiary of
         Bancorp) (the "Exchange Agent"), for the benefit of the holders
         of CBI Certificates, for exchange in accordance with this Ar-
         ticle II, certificates representing the shares of Bancorp Com-
         mon Stock and the cash in lieu of any fractional shares (such
         cash and certificates for shares of Bancorp Common Stock, to-
         gether with any dividends or distributions with respect
         thereto, being hereinafter referred to as the "Exchange Fund")
         to be issued pursuant to Section 1.4 and paid pursuant to Sec-
         tion 2.2(a) in exchange for outstanding shares of CBI Common
         Stock.

                   2.2  Exchange of Shares.  (a)  As soon as practicable
         after the Effective Time, and in no event later than five busi-
         ness days after receipt from CBI or its transfer agent of a
         list of shareholders of record of CBI as of the Effective Time,
         the Exchange Agent shall mail to each holder of record of a CBI
         Certificate or Certificates a form letter of transmittal (which
         shall specify that delivery shall be effected, and risk of loss
         and title to the Certificates shall pass, only upon delivery of
         CBI Certificates to the Exchange Agent) and instructions for
         use in effecting the surrender of CBI Certificates in exchange
         for certificates representing the shares of Bancorp Common
         Stock and the cash in lieu of fractional shares, if any, into
         which the shares of CBI Common Stock represented by such the
         CBI Certificate or Certificates shall have been converted pur-
         suant to this Agreement.  Upon proper surrender of a CBI Cer-
         tificate for exchange and cancellation to the Exchange Agent,
         together with such properly completed letter of transmittal,
         duly executed, the holder of such CBI Certificate shall be en-
         titled to receive in exchange therefor, as applicable, (i) a
         certificate representing that number of whole shares of Bancorp
         Common Stock into which the shares of CBI Common Stock thereto-
         fore represented by the CBI Certificate so surrendered shall
         have been converted pursuant to the provisions of Article I
         hereof and (ii) a check representing the amount of cash in lieu
         of fractional shares, if any, that such holder has the right to
         receive in respect of the CBI Certificate surrendered pursuant 



                                       -4-<PAGE>







         to the provisions of Article II and the CBI Certificate so sur-
         rendered shall forthwith be canceled.  No interest will be paid
         or accrued on the cash in lieu of fractional shares and unpaid
         dividends and distributions, if any, payable to holders of CBI
         Certificates.  Notwithstanding anything to the contrary con-
         tained herein, no certificate representing Bancorp Common Stock
         or cash in lieu of a fractional share interest shall be deliv-
         ered to a person who is an Affiliate (as defined in Section
         6.5) of CBI unless such Affiliate has theretofore executed and
         delivered to Bancorp the agreement referred to in Section 6.5.

                   (b)  No dividends or other distributions declared
         after the Effective Time with respect to Bancorp Common Stock
         shall be paid to the holder of any unsurrendered CBI Certifi-
         cate until the holder thereof shall surrender such CBI Certifi-
         cate in accordance with this Article II.  After the surrender
         of a CBI Certificate in accordance with this Article II, the
         record holder thereof shall be entitled to receive any such
         dividends or other distributions, without any interest thereon,
         that theretofore had become payable with respect to shares of
         Bancorp Common Stock represented by such CBI Certificate.

                   (c)  If any certificate representing shares of Ban-
         corp Common Stock is to be issued in a name other than that in
         which the CBI Certificate surrendered in exchange therefor is
         registered, it shall be a condition of the issuance thereof
         that the CBI Certificate so surrendered shall be properly en-
         dorsed (or accompanied by an appropriate instrument of trans-
         fer) and otherwise in proper form for transfer and that the
         person requesting such exchange shall pay to the Exchange Agent
         in advance any transfer or other taxes requested by reason of
         the issuance of a certificate representing shares of Bancorp
         Common Stock in any name other than that of the registered
         holder of the CBI Certificate surrendered, or required for any
         other reason, or shall establish to the satisfaction of the
         Exchange Agent that such tax has been paid or is not payable.

                   (d)  After the Effective Time, there shall be no
         transfers on the stock transfer books of CBI of the shares of
         CBI Common Stock that were issued and outstanding immediately
         prior to the Effective Time.  If, after the Effective Time, CBI
         Certificates representing such shares are presented for trans-
         fer to the Exchange Agent, they shall be canceled and exchanged
         for certificates representing shares of Bancorp Common Stock as
         provided in this Article II.

                   (e)  Notwithstanding anything to the contrary con-
         tained herein, no certificates or scrip representing fractional 





                                       -5-<PAGE>







         shares of Bancorp Common Stock shall be issued upon the sur-
         render for exchange of CBI Certificates, no dividend or distri-
         bution with respect to Bancorp Common Stock shall be payable on
         or with respect to any fractional share, and such fractional
         share interests shall not entitle the owner thereof to vote or
         to any other rights of a shareholder of CBI.  In lieu of the
         issuance of any such fractional share, Bancorp shall pay to
         each former shareholder of CBI who otherwise would be entitled
         to receive such fractional share an amount in cash determined
         by multiplying (i) the average of the closing-sale prices of
         Bancorp Common Stock on the NASDAQ Stock Market National Market
         System as reported by The Wall Street Journal for the five
         trading days immediately preceding the date of the Effective
         Time by (ii) the fraction of a share of Bancorp Common Stock
         which such holder would otherwise be entitled to receive pursu-
         ant to Section 1.4.

                   (f)  Any portion of the Exchange Fund that remains
         unclaimed by the shareholders of CBI for twelve months after
         the Effective Time shall be paid to Bancorp.  Any shareholders
         of CBI who have not theretofore complied with this Article II
         shall thereafter look only to Bancorp for payment of the shares
         of Bancorp Common Stock, cash in lieu of any fractional shares
         and unpaid dividends and distributions on the Bancorp Common
         Stock deliverable in respect of each share of CBI Common Stock
         that such shareholder is entitled to receive pursuant to this
         Agreement, without any interest thereon.  Notwithstanding the
         foregoing, none of Bancorp, CBI, the Exchange Agent or any
         other person shall be liable to any former holder of shares of
         CBI Stock for any amount properly delivered to a public of-
         ficial pursuant to applicable abandoned property, escheat or
         similar laws.

                   (g)  In the event any CBI Certificate shall have been
         lost, stolen or destroyed, upon the making of an affidavit of
         that fact by the person claiming such CBI Certificate to be
         lost, stolen or destroyed and, if required by Bancorp, the
         posting by such person of a bond in such amount as Bancorp may
         determine is reasonably necessary as indemnity against any
         claim that may be made against it with respect to such CBI Cer-
         tificate, the Exchange Agent will issue in exchange for such
         lost, stolen or destroyed CBI Certificate the shares of Bancorp
         Common Stock and cash in lieu of fractional shares deliverable
         in respect thereof pursuant to this Agreement.

                                   ARTICLE III
                      REPRESENTATIONS AND WARRANTIES OF CBI

                   Except as set forth in the disclosure schedule of CBI
         delivered to Bancorp concurrently herewith (the "CBI Disclosure
         Schedule"), CBI hereby represents and warrants to Bancorp as
         follows:

                   3.1.  Corporate Organization.  (a)  CBI is a corpora-
         tion duly organized and validly existing under the laws of the
         state of Delaware.  CBI has the corporate power and authority
         to own or lease all of its properties and assets and to carry
         on its business as it is now being conducted, and is duly li-
         censed or qualified to do business in each jurisdiction in
         which the nature of the business conducted by it or the charac-
         ter or location of the properties and assets owned or leased by
         it makes such licensing or qualification necessary, except
         where the failure to be so licensed or qualified would not have
         a Material Adverse Effect (as defined below) on CBI.  As used
         in this Agreement, the term "Material Adverse Effect" means,
         with respect to Bancorp, CBI or the Surviving Corporation, as
         the case may be, a material adverse effect on the business,
         results of operations or financial condition of such party and
         its Subsidiaries taken as a whole.  As used in this Agreement,
         the word "Subsidiary" when used with respect to any party means
         any bank, corporation, partnership or other organization,
         whether incorporated or unincorporated, that is consolidated
         with such party for financial reporting purposes.  CBI is duly
         registered as a bank holding company under the Bank Holding
         Company Act of 1956, as amended (the "BHC Act").  The Certifi-
         cate of Incorporation and Bylaws of CBI, copies of which have
         previously been made available to Bancorp, are true, complete
         and correct copies of such documents as in effect as of the
         date of this Agreement.

                   (b)  CBI has previously delivered to Bancorp a sched-
         ule listing each CBI Subsidiary and setting forth for each such
         CBI Subsidiary the (i) jurisdiction in which it is organized,
         (ii) jurisdictions in which it is qualified to do business, and
         (iii) office or agency having primary regulatory authority over
         its business and operations.  Each CBI Subsidiary (i) is duly
         organized and validly existing as a bank, corporation or part-
         nership under the laws of its jurisdiction of organization,
         (ii) is duly qualified to do business and in good standing in
         all jurisdictions (whether federal, state, local or foreign)
         where its ownership or leasing of property or the conduct of
         its business requires it to be so qualified and in which the
         failure to be so qualified would have a Material Adverse Effect 





                                       -7-<PAGE>







         on CBI, and (iii) has all requisite corporate power and author-
         ity to own or lease its properties and assets and to carry on
         its business as now conducted.

                   (c)  The minute books of CBI accurately reflect in
         all material respects all corporate actions since January 1,
         1993, of its shareholders and Board of Directors (including
         committees of the Board of Directors of CBI).

                   3.2.  Capitalization.  (a)  The authorized capital
         stock of CBI consists of 16,000,000 shares of CBI Common Stock
         and 2,000,000 shares of preferred stock, no par value per
         share.  At the close of business on December 31, 1995, there
         were 10,060,685 shares of CBI Common Stock outstanding and no
         shares of CBI preferred stock outstanding.  On December 31,
         1995, no shares of CBI Common Stock or CBI preferred stock were
         reserved for issuance, except that (i) 305,846 shares of CBI
         Common Stock were reserved for issuance pursuant to CBI's divi-
         dend reinvestment and stock purchase plan (the "CBI DRIP"),
         (ii) 2,125,110 shares of CBI Common Stock were reserved for
         issuance upon the exercise of stock options pursuant to the
         1990 Stock Incentive Plan and the Directors Stock Option Plan
         (the "CBI Stock Plans"), (iii) 400,000 shares of CBI Series A
         junior participating preferred stock, no par value, were re-
         served for issuance upon exercise of the rights (the "CBI
         Rights") distributed to holders of CBI Common Stock pursuant to
         the Rights Agreement, dated as of June 30, 1995, between CBI
         and First Interstate Bank of California, as Rights Agent (the
         "CBI Rights Agreement"), and (iv) the shares of CBI Common
         Stock issuable pursuant to the CBI Option Agreement.  All of
         the issued and outstanding shares of CBI Common Stock have been
         duly authorized and validly issued and are fully paid, non-
         assessable and free of preemptive rights with no personal li-
         ability attaching to the ownership thereof.  Except as stated
         above, CBI does not have and is not bound by any outstanding
         subscriptions, options, warrants, calls, commitments or agree-
         ments of any character calling for the purchase or issuance of
         any shares of CBI Common Stock or CBI preferred stock or any
         other equity securities of CBI or any securities representing
         the right to purchase or otherwise receive any shares of CBI
         Common Stock or CBI preferred stock.  CBI has previously pro-
         vided Bancorp with a list of the option holders, the date of
         each option to purchase CBI Common Stock granted, the number of
         shares subject to each such option, the expiration date of each
         such option, and the price at which each such option may be
         exercised under the CBI Stock Plans.  As reflected on such
         list, options for 677,555 shares were outstanding at December
         31, 1995, all of which will be exercisable prior to the Effec-
         tive Time in accordance with their terms.  Since December 31,
         1995, CBI has not issued any shares of its capital stock or any 




                                       -8-<PAGE>







         securities convertible into or exercisable for any shares of
         its capital stock, other than pursuant to the exercise of em-
         ployee stock options.

                   (b)  CBI owns directly all of the issued and out-
         standing shares of capital stock of each of the CBI Subsidiar-
         ies, free and clear of any liens, charges, encumbrances and
         security interests whatsoever, and all of such shares are duly
         authorized and validly issued and are fully paid, nonassessable
         and free of preemptive rights, with no personal liability at-
         taching to the ownership thereof.  No CBI Subsidiary has or is
         bound by any outstanding subscriptions, options, warrants,
         calls, commitments or agreements of any character calling for
         the purchase or issuance of any shares of capital stock or any
         other equity security of such Subsidiary or any securities rep-
         resenting the right to purchase or otherwise receive any shares
         of capital stock or any other equity security of such Subsid-
         iary.  Assuming compliance by Bancorp with Section 1.6 hereof,
         at the Effective Time, there will not be any outstanding sub-
         scriptions, options, warrants, calls, commitments or agreements
         of any character by which CBI or any of its Subsidiaries will
         be bound calling for the purchase or issuance of any shares of
         the capital stock of CBI or any of its Subsidiaries.

                   3.3.  Authority; No Violation.  (a)  CBI has full
         corporate power and authority to execute and deliver this
         Agreement and to consummate the transactions contemplated
         hereby.  The execution and delivery of this Agreement and the
         consummation of the transactions contemplated hereby have been
         duly and validly approved by the Board of Directors of CBI.
         The Board of Directors of CBI has directed that this Agreement
         and the transactions contemplated hereby be submitted to CBI's
         shareholders for approval at a meeting of such shareholders
         and, except for the adoption of this Agreement by the affirma-
         tive vote of the holders of a majority of the outstanding
         shares of CBI Common Stock, no other corporate proceedings on
         the part of CBI are necessary to approve this Agreement and to
         consummate the transactions contemplated hereby.  This Agree-
         ment has been duly and validly executed and delivered by CBI
         and (assuming due authorization, execution and delivery by Ban-
         corp) constitutes a valid and binding obligation of CBI, en-
         forceable against CBI in accordance with its terms, except as
         enforcement may be limited by general principles of equity
         whether applied in a court of law or a court of equity and by
         bankruptcy, insolvency and similar laws affecting creditors'
         rights and remedies generally.

                   (b)  Neither the execution and delivery of this
         Agreement by CBI nor the consummation by CBI of the transac-
         tions contemplated hereby, nor compliance by CBI with any of 




                                       -9-<PAGE>







         the terms or provisions hereof, will (i) violate any provision
         of the Certificate of Incorporation or Bylaws of CBI or (ii)
         assuming that the consents and approvals referred to in Section
         3.4 are duly obtained (x) violate any statute, code, ordinance,
         rule, regulation, judgment, order, writ, decree or injunction
         applicable to CBI or any of its Subsidiaries or any of their

         result in a breach of any provision of or the loss of any ben-
         efit under, constitute a default (or an event that, with notice
         or lapse of time, or both, would constitute a default) under,
         result in the termination of or a right of termination or can-
         cellation under, accelerate the performance required by, or
         result in the creation of any lien, pledge, security interest,
         charge or other encumbrance upon any of the respective proper-
         ties or assets of CBI or any of its Subsidiaries under, any of
         the terms, conditions or provisions of any note, bond, mort-
         gage, indenture, deed of trust, license, lease, agreement or
         other instrument or obligation to which CBI or any of its Sub-
         sidiaries is a party, or by which they or any of their respec-
         tive properties or assets may be bound or affected, except (in
         case of clause (y) above) for such violations, conflicts,
         breaches or defaults that, either individually or in the ag-
         gregate, will not have or be reasonably likely to have a Mate-
         rial Adverse Effect on CBI.

                   3.4.  Consents and Approvals.  Except for (i) the
         filing of the applications and notices, as applicable, with the
         Board of Governors of the Federal Reserve System (the "Federal
         Reserve Board") under the BHC Act, (ii) the filing of any req-
         uisite applications with the Office of the Comptroller of the

         tions or notices with any state bank regulatory agencies (the
         "State Approvals"), (iv) the filing with the SEC of a proxy

         shareholders to be held in connection with this Agreement and
         the transactions contemplated hereby (the "Proxy Statement")
         and the registration statement on Form S-4 (the "S-4") in which
         the Proxy Statement will be included as a prospectus, (v) the
         filing of the Articles of Merger with the Oregon Secretary pur-

         Stock pursuant to this Agreement, (viii) the approval of this

                                       -10-<PAGE>







         Schedule, no consents or approvals of or filings or registra-
         tions with any court, administrative agency or commission or
         other governmental authority or instrumentality (each a "Gov-
         ernmental Entity") or with any third party are necessary in
         connection with (A) the execution and delivery by CBI of this
         Agreement and (B) the consummation by CBI of the Merger and the
         other transactions contemplated hereby.

                   3.5.  Reports.  CBI and each of its Subsidiaries have
         timely and properly filed all material reports, registrations
         and statements, together with any amendments required to be
         made with respect thereto, that they were required to file
         since January 1, 1993, with (i) the Federal Reserve Board, (ii)
         the Office of Thrift Supervision (the "OTS") under the Home
         Owners' Loan Act ("HOLA"), (iii) any state regulatory authority
         (each a "State Regulator"), (iv) the OCC, (v) the FDIC, and
         (vi) any other self-regulatory organization ("SRO") (col-
         lectively, "Regulatory Agencies"), and all other material re-
         ports and statements required to be filed by them since January
         1, 1993, and have paid all fees and assessments due and payable
         in connection therewith.  Except for normal examinations con-
         ducted by a Regulatory Agency in the regular course of the
         business of CBI and its Subsidiaries, no Regulatory Agency has
         initiated any proceeding or, to the best knowledge of CBI, in-
         vestigation into the business or operations of CBI or any of
         its Subsidiaries since January 1, 1993.  There is no material
         unresolved violation, criticism, or exception by any Regulatory
         Agency with respect to any report or statement relating to any
         examinations of CBI or any of its Subsidiaries.

                   3.6.  Financial Statements.  CBI has previously de-
         livered to Bancorp copies of (a) the consolidated balance
         sheets of CBI and its Subsidiaries as of December 31, for the
         fiscal years 1993 and 1994, and the related consolidated state-
         ments of income, changes in stockholders' equity and cash flows
         for the fiscal years 1992 through 1994, inclusive, as reported
         in CBI's Annual Report on Form 10-K for the fiscal year ended
         December 31, 1994, filed with the SEC under the Securities Ex-
         change Act of 1934, as amended (the "Exchange Act"), in each
         case accompanied by the audit report of KPMG Peat Marwick LLP,
         independent public accountants, with respect to CBI, (b) the
         unaudited consolidated balance sheet of CBI and its Subsidiar-
         ies as of December 31, 1995, and the related unaudited consoli-
         dated statements of income, cash flows and changes in stock-
         holders' equity for the fiscal year 1995 substantially in the
         form that is proposed to be reported in CBI's Annual Report on
         Form 10-K for the period ended December 31, 1995, filed with 






                                       -11-<PAGE>







         the SEC under the Exchange Act, and (c) the unaudited consoli-
         dated balance sheets of CBI as of September 30, 1995, and Sep-
         tember 30, 1994, and the related unaudited consolidated state-
         ments of income, cash flows, and changes in stockholders' eq-
         uity for the nine months then ended as reported in CBI's Quar-
         terly Report on Form 10-Q for the period ended September 30,
         1995, filed with the SEC under the Exchange Act.  The financial
         statements referred to in this Section 3.6 (including the re-
         lated notes, where applicable) fairly present (subject, in the
         case of the unaudited statements, to recurring audit adjust-
         ments normal in nature and amount), the results of the consoli-
         dated operations and changes in stockholders' equity and con-
         solidated financial position of CBI and its Subsidiaries for
         the respective fiscal periods or as of the respective dates
         therein set forth; each of such statements (including the re-
         lated notes, where applicable) comply in all material respects
         with applicable accounting requirements and with the published
         rules and regulations of the SEC with respect thereto and each
         of such statements (including the related notes, where ap-
         plicable) has been prepared in accordance with generally ac-
         cepted accounting principles ("GAAP") consistently applied dur-
         ing the periods involved, except in each case as indicated in
         such statements or in the notes thereto or, in the case of un-
         audited quarterly statements, as permitted by Form 10-Q.  The
         allowances for credit losses contained in the financial state-
         ments referred to in this Section 3.6 were adequate as of their
         respective dates to absorb reasonably anticipated losses in the
         loan portfolio of CBI and its Subsidiaries in view of the size
         and character of such portfolio, the current economic condi-
         tions, and other pertinent factors and no facts have subse-
         quently come to the attention of management of CBI that would
         cause management to restate in any material way the level of
         such allowance for credit losses.  With respect to other real
         estate owned by CBI and its Subsidiaries, the value attributed
         thereto for purposes of compiling such financial statements
         does not exceed the aggregate fair market value of such real
         estate as of the date of acquisition of such real estate or as
         subsequently reduced, all in accordance with regulations of the
         applicable Regulatory Agencies.  The books and records of CBI
         and its Subsidiaries have been, and are being, maintained in
         all material respects in accordance with GAAP and any other
         applicable legal and accounting requirements and reflect only
         actual transactions.

                   3.7.  Broker's Fees.  Except for the services of
         Goldman, Sachs & Co. pursuant to an agreement dated Novem-
         ber 21, 1995, a copy of which has previously been provided to
         Bancorp, neither CBI nor any CBI Subsidiary nor any of their
         respective officers or directors has employed any broker or 




                                       -12-<PAGE>







         finder or incurred any liability for any broker's fees, com-
         missions or finder's fees in connection with any of the trans-
         actions contemplated by this Agreement, or the CBI Option
         Agreement.

                   3.8.  Absence of Certain Changes or Events.  (a)  Ex-
         cept as publicly disclosed in CBI Reports (as defined below)
         filed prior to the date hereof, since December 31, 1994, (i)
         neither CBI nor any of its Subsidiaries has incurred any mate-
         rial liability, except in the ordinary course of their business
         consistent with their past practices, and (ii) no event has
         occurred that has had, or is reasonably likely to have, indi-
         vidually or in the aggregate, a Material Adverse Effect on CBI.

                   (b)  Except as publicly disclosed in CBI Reports
         filed prior to the date hereof, since December 31, 1994, CBI
         and its Subsidiaries have carried on their respective busi-
         nesses in the ordinary and usual course consistent with their
         past practices.

                   (c)  Since January 1, 1995, neither CBI nor any of
         its Subsidiaries has (i) except for normal increases in the
         ordinary course of business consistent with past practice or
         except as required by applicable law, increased the wages,
         salaries, compensation, pension, or other fringe benefits or
         perquisites payable to any executive officer, employee, or di-
         rector from the amount thereof in effect as of January 1, 1995,
         granted any severance or termination pay, entered into any con-
         tract to make or grant any severance or termination pay, or
         paid any bonus other than customary year-end bonuses, (ii) suf-
         fered any strike, work stoppage, slowdown, or other labor dis-
         turbance, or (iii) been the subject of any organizing activi-
         ties known to CBI.

                   3.9.  Legal Proceedings.  (a)  Except as publicly
         disclosed in CBI Reports filed prior to the date hereof, nei-
         ther CBI nor any of its Subsidiaries is a party to any, and
         there are no pending or, to the best of CBI's knowledge,
         threatened, material legal, administrative, arbitral or other
         proceedings, claims, actions or governmental or regulatory in-
         vestigations of any nature (i) against CBI or any of its Sub-
         sidiaries as to which there is a reasonable possibility of an
         adverse determination and which, if adversely determined,
         would, individually or in the aggregate, have a Material Ad-
         verse Effect on CBI or (ii) challenging the validity or propri-
         ety of the transactions contemplated by this Agreement or the
         CBI Option Agreement.






                                       -13-<PAGE>







                   (b)  There is no injunction, order, judgment, decree,
         or regulatory restriction imposed upon CBI, any of its Subsid-
         iaries or the assets of CBI or any of its Subsidiaries that has
         had, or might reasonably be expected to have, a Material Ad-
         verse Effect on CBI.

                   3.10.  Taxes and Tax Returns.  (a)  Each of CBI and
         its Subsidiaries has duly filed all material federal, state
         and, to the best of CBI's knowledge, material local information
         returns and tax returns required to be filed by it (all such
         returns being accurate and complete in all material respects)
         and has duly paid or made provisions for the payment of all
         material Taxes (as defined below) and other governmental
         charges which have been incurred or are due or claimed to be
         due from it by federal, state, county or local taxing authori-
         ties (including, without limitation, if and to the extent ap-
         plicable, those due in respect of its properties, income, busi-
         ness, capital stock, deposits, franchises, licenses, sales and
         payrolls) other than Taxes or other charges that (1) are not
         yet delinquent or are being contested in good faith and (2)
         have not been finally determined.  The income tax returns of
         CBI and its Subsidiaries have been examined by the Internal
         Revenue Service (the "IRS"), and any liability with respect
         thereto has been satisfied for all years to and including 1981,
         and no material deficiencies were asserted as a result of such
         examination or all such deficiencies were satisfied.  To the
         best of CBI's knowledge, there are no material disputes pend-
         ing, or claims asserted for, Taxes or assessments upon CBI or
         any of its Subsidiaries, nor has CBI or any of its Subsidiaries
         been requested to give any currently effective waivers extend-
         ing the statutory period of limitation applicable to any fed-
         eral, state, county or local income tax return for any period.
         In addition, (i) proper and accurate amounts have been withheld
         by CBI and its Subsidiaries from their employees for all prior
         periods in compliance in all material respects with the tax
         withholding provisions of applicable federal, state and local
         laws, except where failure to do so would not have a Material
         Adverse Effect on CBI, (ii) federal, state, county and local
         returns that are accurate and complete in all material respects
         have been filed by CBI and its Subsidiaries for all periods for
         which returns were due with respect to income tax withholding,
         Social Security and unemployment taxes, except where failure to
         do so would not have a Material Adverse Effect on CBI, (iii)
         the amounts shown on such federal, state, local or county re-
         turns to be due and payable have been paid in full or adequate
         provision therefor has been included by CBI in its consolidated
         financial statements as of December 31, 1995, except where
         failure to do so would not have a Material Adverse Effect on
         CBI and (iv) there are no tax liens upon any property or assets
         of CBI or its Subsidiaries except liens for current taxes not 




                                       -14-<PAGE>







         yet due.  To the knowledge of CBI, no property of CBI or any of
         its Subsidiaries is property that CBI or any of its Subsidiar-
         ies is or will be required to treat as being owned by another
         person pursuant to the provisions of Section 168(f)(8) of the
         Code (as in effect prior to its amendment by the Tax Reform Act
         of 1986) or is "tax-exempt use property" within the meaning of
         Section 169(h) of the Code.  Neither CBI nor any of its Subsid-
         iaries has been required to include in income any adjustment
         pursuant to Section 481 of the Code by reason of a voluntary
         change in accounting method initiated by CBI or any of its Sub-
         sidiaries, and the Internal Revenue Service has not initiated
         or proposed any such adjustment or change in accounting method.
         Except as set forth in the financial statements described in
         Section 3.6 hereof, neither CBI nor any of its Subsidiaries has
         entered into a transaction which is being accounted for as an
         installment obligation under Section 453 of the Code, which
         would be reasonably likely to have a Material Adverse Effect on
         CBI.

                   (b)  As used in this Agreement, the term "Tax" or
         "Taxes" means all federal, state, county, local and foreign
         income, excise, gross receipts, ad valorem, profits, gains,
         property, sales, transfer, use, payroll, employment, severance,
         withholding, duties, intangibles, franchise, and other taxes,
         charges, levies or like assessments together with all penalties
         and additions to tax and interest thereon.

                   (c)  Any amount that could be received (whether in
         cash or property or the vesting of property) as a result of any
         of the transactions contemplated by this Agreement by any em-
         ployee, officer or director of CBI or any of its affiliates who
         is a "Disqualified Individual" (as such term is defined in pro-
         posed Treasury Regulation Section 1.280G-1) under any employ-
         ment, severance or termination agreement, other compensation
         arrangement or CBI Benefit Plan (as defined below) currently in
         effect would not be characterized as an "excess parachute pay-
         ment" (as such term is defined in Section 280G(b)(1) of the
         Code).

                   (d)  No disallowance of a deduction under Section
         162(m) of the Code for employee remuneration of any amount paid
         or payable by CBI or any Subsidiary of CBI under any contract,
         plan, program, arrangement or understanding is reasonably
         likely.

                   3.11.  Employees.  (a)  The CBI Disclosure Schedule
         sets forth a true and complete list of each material plan, ar-
         rangement or agreement regarding compensation or benefits for
         any employees, former employees, directors, or former directors
         that is maintained as of the date of this Agreement (the "CBI 



                                       -15-<PAGE>







         Benefit Plans") by CBI or any of its Subsidiaries or by any
         trade or business, whether or not incorporated (an "ERISA Af-
         filiate"), all of which together with CBI would be deemed a
         "single employer" with the meaning of Section 4001 of the Em-
         ployee Retirement Income Security Act of 1974, as amended
         ("ERISA").

                   (b)  CBI has heretofore delivered to Bancorp true and
         complete copies of each of the CBI Benefit Plans and all re-
         lated documents, including but not limited to (i) the actuarial
         report for such Plan (if applicable) for each of the last two
         years, and (ii) the most recent determination letter from the
         Internal Revenue Service (if applicable) for such Plan.

                   (c)  (i) Each of the CBI Benefit Plans has been oper-
         ated and administered in all material respects in compliance
         with applicable laws, including but not limited to ERISA and
         the Code, (ii) each of the CBI Benefit Plans intended to be
         "qualified" within the meaning of Section 401(a) of the Code is
         so qualified, (iii) with respect to each CBI Benefit Plan that
         is subject to Title IV of ERISA, the present value of accrued
         benefits under such CBI Benefit Plan, based upon the actuarial
         assumptions used for funding purposes in the most recent actu-
         arial report prepared by such CBI Benefit Plan's actuary with
         respect to such CBI Benefit Plan, did not, as of its latest
         valuation date, exceed the then current value of the assets of
         such CBI Benefit Plan allocable to such accrued benefits, (iv)
         no CBI Benefit Plan provides benefits, including, without limi-
         tation, death or medical benefits (whether or not insured),
         with respect to current or former employees of CBI, its Subsid-
         iaries or any ERISA Affiliate beyond their retirement or other
         termination of service, other than (w) coverage mandated by
         applicable law, (x) death benefits or retirement benefits under
         any "employee pension plan," as that term is defined in Section
         3(2) of ERISA, (y) deferred compensation benefits accrued as
         liabilities on the books of CBI, its Subsidiaries or the ERISA
         Affiliates or (z) benefits the full cost of which is borne by
         the current or former employee (or his beneficiary), (v) no
         liability under Title IV of ERISA has been incurred by CBI, its
         Subsidiaries or any ERISA Affiliate that has not been satisfied
         in full, and no condition exists that presents a material risk
         to CBI, its Subsidiaries or any ERISA Affiliate of incurring a
         material liability thereunder, (vi) no CBI Benefit Plan is a
         "multiemployer pension plan," as such term is defined in Sec-
         tion 3(37) of ERISA, (vii) all contributions or other amounts
         payable by CBI or its Subsidiaries as of the Effective Time
         with respect to each CBI Benefit Plan in respect of current or
         prior plan years have been paid or accrued in accordance with
         generally accepted accounting practices and Section 412 of the 




                                       -16-<PAGE>







         Code, (viii) neither CBI, its Subsidiaries nor any ERISA Af-
         filiate has engaged in a transaction in connection with which
         CBI, its Subsidiaries or any ERISA Affiliate could be subject
         to either a material civil penalty assessed pursuant to Section
         409 or 502(i) of ERISA or a material tax imposed pursuant to
         Section 4975 or 4976 of the Code, and (ix) to the best knowl-
         edge of CBI there are no pending, threatened or anticipated
         claims (other than routine claims for benefits) by, on behalf
         of or against any of the CBI Benefit Plans or any trusts re-
         lated thereto.

                   (d)  Neither the execution and delivery of this
         Agreement nor the consummation of the transactions contemplated
         hereby will (i) result in any material payment (including,
         without limitation, severance, unemployment compensation,
         golden parachute or otherwise) becoming due to any director or
         any employee of CBI or any of its affiliates from CBI or any of
         its affiliates under any CBI Benefit Plan or otherwise, (ii)
         materially increase any benefits otherwise payable under any
         CBI Benefit Plan or (iii) result in any acceleration of the
         time of payment or vesting of any such benefits to any material
         extent.

                   (e)  CBI has previously delivered to Bancorp a sched-
         ule setting forth for each management employee of CBI or its
         Subsidiaries who is a party to any employment, golden para-
         chute, or severance agreement, the approximate maximum amount
         of payments and benefits other than vested retirement benefits
         and previously deferred compensation to which each such em-
         ployee will become entitled in the event that such employee's
         employment is terminated following the consummation of the
         Merger.

                   3.12.  SEC Reports.  CBI has previously made avail-
         able, to Bancorp an accurate and complete copy of each (a) fi-
         nal registration statement, prospectus, report, schedule and
         definitive proxy statement filed since January 1, 1994 by CBI
         with the SEC pursuant to the Securities Act of 1933, as amended
         (the "Securities Act"), or the Exchange Act (the "CBI Reports")
         and prior to the date hereof and (b) communication mailed by
         CBI to its shareholders since January 1, 1994, and no such reg-
         istration statement, prospectus, report, schedule, proxy state-
         ment or communication contained any untrue statement of a mate-
         rial fact or omitted to state any material fact required to be
         stated therein or necessary in order to make the statements
         therein, in light of the circumstances under which they were
         made, not misleading, except that information as of a later
         date shall be deemed to modify information as of an earlier
         date.  CBI has timely filed all CBI Reports and other documents
         required to be filed by it under the Securities Act and the 



                                       -17-<PAGE>







         Exchange Act, and, as of their respective dates, all CBI Re-
         ports complied in all material respect with the published rules
         and regulations of the SEC with respect thereto.

                   3.13.  Compliance with Applicable Law.  (a)  CBI and
         each of its Subsidiaries hold, and have at all times held, all
         material licenses, franchises, permits and authorizations nec-
         essary for the lawful conduct of their respective businesses
         under and pursuant to all, and have complied with and are not
         in default in any material respect under any, applicable laws,
         statutes, orders, rules, regulations of any Governmental Entity
         relating to CBI or any of its Subsidiaries, except where the
         failure to hold such license, franchise, permit or authoriza-
         tion or such noncompliance or default would not, individually
         or in the aggregate, have a Material Adverse Effect on CBI, and
         neither CBI nor any of its Subsidiaries knows of, or has re-
         ceived notice of, any material violations of any of the above.

                   (b)  Except as would not have a Material Adverse Ef-
         fect, (i) no real property presently or previously owned, oper-
         ated, or leased by CBI or any of its Subsidiaries or, to the
         best of their knowledge, securing any obligations owed to them
         has been used as a storage or disposal site for hazardous sub-
         stances within the meaning of any applicable federal, state, or
         local statute, law, rule, or regulation, and no hazardous sub-
         stances have been transferred from or to such real property,
         (ii) no governmental entity has issued any citation or notice
         of violation relating to any environmental matter concerning
         any real property owned, operated, or leased by CBI or any of
         its Subsidiaries or, to the best of their knowledge securing
         any obligations owed to them, and neither CBI nor any of its
         Subsidiaries has received any notice that any such real prop-
         erty may or will be included on any list of areas affected by
         any release of any hazardous substance or that it has or may be
         named as a responsible or potentially responsible party with
         respect to any hazardous substance site, and (iii) neither CBI
         nor any of its Subsidiaries has received any notice of any
         threatened investigation, proceeding, or litigation concerning
         any such real property with respect to any environmental matter
         or knows of any basis for any such investigation, proceeding,
         or litigation.

                   3.14.  Certain Contracts.  (a)  Neither CBI nor any
         of its Subsidiaries is a party to or bound by any contract, ar-
         rangement, commitment or understanding (whether written or
         oral) (i) with respect to the employment of any directors, of-
         ficers, employees or consultants, (ii) that, upon the consum-
         mation of the transactions contemplated by this Agreement will
         (either alone or upon the occurrence of any additional acts or 




                                       -18-<PAGE>







         events) result in any payment (whether of severance pay or oth-
         erwise) becoming due from Bancorp, CBI, the Surviving Corpora-
         tion, or any of their respective Subsidiaries to any officer or
         employee thereof, (iii) that is a material contract (as defined
         in Item 601(b)(10) of Regulation S-K of the SEC) to be per-
         formed after the date of this Agreement that has not been filed
         or incorporated by reference in the CBI Reports, (iv) that ma-
         terially restricts the conduct of any line of business by CBI,
         (v) with or to a labor union or guild (including any collective
         bargaining agreement) or (vi) (including any stock option plan,
         stock appreciation rights plan, restricted stock plan or stock
         purchase plan) any of the benefits of which will be increased,
         or the vesting of the benefits of which will be accelerated, by
         the occurrence of any of the transactions contemplated by this
         Agreement, or the value of any of the benefits of which will be
         calculated on the basis of any of the transactions contemplated
         by this Agreement.  CBI has delivered to Bancorp a complete
         list as of the date of this Agreement of each contract to which
         CBI or any of its Subsidiaries is a party that involves an
         amount in excess of $100,000 or that has an unexpired term in
         excess of one year from the date of this Agreement other than
         loans, deposits, letters of credit, and similar transactions
         entered into by CBI in the ordinary course of business.  In
         addition, CBI has previously delivered to Bancorp true and cor-
         rect copies of all employment, consulting, and deferred com-
         pensation agreements that are in writing and a written summary
         of all such contracts that are material to CBI and not in writ-
         ing.  Each contract, arrangement, commitment or understanding
         of the type described in Section 3.14(a), whether or not set
         forth in the CBI Disclosure Schedule, is referred to herein as
         a "CBI Contract."  Neither CBI nor any of its Subsidiaries
         knows of, or has received notice of, any violation of any CBI
         Contract by any of the other parties thereto that, individually
         or in the aggregate, would have a Material Adverse Effect on
         CBI.

                   (b)  (i) Each CBI Contract is valid and binding and
         in full force and effect, (ii) CBI and each of its Subsidiaries
         has in all material respects performed all obligations required
         to be performed by it to date under each CBI Contract, except
         where such noncompliance, individually or in the aggregate,
         would not have a Material Adverse Effect on CBI, and (iii) no
         event or condition exists that constitutes or, after notice or
         lapse of time or both, would constitute, a material default on
         the part of CBI or any of its Subsidiaries or, to the knowledge
         of CBI, on the part of any other party under any such CBI Con-
         tract, except where such default, individually or in the ag-
         gregate, would not have a Material Adverse Effect on CBI.

                   3.15.  Agreements with Regulatory Agencies.  Neither
         CBI nor any of its Subsidiaries is subject to any cease-and-
         desist or other order issued by, or is a party to any written
         agreement, consent agreement or memorandum of understanding
         with, or is a party to any commitment letter or similar under-
         taking to, or is subject to any order or directive by, or is a
         recipient of any supervisory letter from, or has adopted any
         resolutions at the request of (each, whether or not set forth
         in the CBI Disclosure Schedule, a "Regulatory Agreement"), any
         Regulatory Agency or other Governmental Entity that restricts
         the conduct of its business or that in any manner relates to
         its capital adequacy, its credit policies, its management or
         its business, nor has CBI or any of its Subsidiaries been ad-
         vised by any Regulatory Agency or other Governmental Entity
         that it is considering issuing or requesting any Regulatory
         Agreement.

                   3.16.  Undisclosed Liabilities.  Except for those li-
         abilities that are fully reflected or reserved against on the
         consolidated balance sheet of CBI as of December 31, 1995, and
         for liabilities incurred in the ordinary course of business
         consistent with past practice, since December 31, 1995, neither
         CBI nor any of its Subsidiaries has incurred any liability of
         any nature whatsoever (whether absolute, accrued, contingent or
         otherwise and whether due or to become due) that, either alone
         or when combined with all similar liabilities, has had, or
         could reasonably be expected to have, a Material Adverse Effect
         on CBI.

                   3.17.  State Takeover Laws.  The Board of Directors
         of CBI has taken such actions as are necessary such that the
         provisions of Section 203 of the DGCL will not apply to this
         Agreement or the CBI Option Agreement or any of the transac-
         tions contemplated hereby or thereby.

                   3.18.  Rights Agreement.  CBI has taken all action
         (including, if required, redeeming all of the outstanding pre-
         ferred stock purchase rights issued pursuant to the CBI Rights
         Agreement or amending or terminating the CBI Rights Agreement)
         so that the entering into of this Agreement and the CBI Option
         Agreement, the Merger, the acquisition of shares pursuant to
         the CBI Option Agreement and the other transactions contem-
         plated hereby and thereby do not and will not result in the
         grant of any rights to any person under the CBI Rights Agree-
         ment or enable or require the CBI Rights to be exercised, dis-
         tributed or triggered.

                   3.19.  Pooling of Interests.  As of the date of this
         Agreement, CBI has no reason to believe that the Merger will
         not qualify as a pooling of interests for accounting purposes.



                                       -20-<PAGE>







                   3.20.  Interest Rate Risk Management Instruments; De-
         rivatives.  (a)  CBI has heretofore delivered to Bancorp an
         accurate and complete list of (A) all interest rate swaps,
         caps, floors, option agreements, and other interest rate risk
         management arrangements and other instruments generally known
         as "derivatives" to which CBI or any of its Subsidiaries is a
         party or to which any of their properties or assets may be sub-
         ject and (B) all securities owned by CBI or its Subsidiaries
         that are generally known as "structured note," "high risk mort-
         gage derivatives," "capped floating rate notes," or "capped
         floating rate mortgage derivatives" (instruments or agreements
         of the type referred to in clauses (A) and (B), collectively,
         "Derivative Securities").  Neither CBI nor any of its Subsid-
         iaries has purchased any Derivative Security for, or invested
         in any Derivative Security any assets of, any account or person
         for which it or any such subsidiary acts as a trustee, fidu-
         ciary, or investment advisor.

                   (b)  All Derivative Securities to which CBI or any of
         its Subsidiaries is a party or to which any of their properties
         or assets may be subject were entered into in the ordinary
         course of business and, to its knowledge, in accordance with
         prudent banking practice and applicable rules, regulations, and
         policies of the Regulatory Agencies and with counterparties
         believed to be financially responsible at the time and are le-
         gal, valid, and binding obligations enforceable in accordance
         with their terms (except as may be limited by bankruptcy, in-
         solvency, moratorium, reorganization, or similar laws affecting
         the rights of creditors generally, and the availability of eq-
         uitable remedies), and are in full force and effect.  CBI and
         each of its Subsidiaries has duly performed in all material
         respects all of its obligations thereunder, and, to its knowl-
         edge, there are no breaches, violations, or defaults or allega-
         tions or assertions of such by any party thereunder.

                   3.21.  Properties.  (a)  Except as would not have a
         Material Adverse Effect on CBI, (i) except for assets disposed
         of in the ordinary course of business, CBI and each of its Sub-
         sidiaries possess good and marketable title to and own, free of
         any encumbrances (other than liens for taxes not yet due,
         statutory rights of redemption with respect to properties ac-
         quired in the course of collecting loans, liens securing in-
         debtedness of not more than $100,000, and easements or rights
         of way of public utilities or similar encumbrances not materi-
         ally interfering with the conduct of business), all of their
         material real, personal, and intangible properties and other
         assets; (ii) the leases pursuant to which CBI or any of its
         Subsidiaries lease real or personal property are valid and ef-
         fective in accordance with their respective terms and, to the 




                                       -21-<PAGE>







         knowledge of CBI, there is not, under any such lease, any mate-
         rial existing default or any event which, with the giving of
         notice or lapse of time or otherwise, would constitute a de-
         fault; (iii) the material properties owned or leased by CBI and
         each of its Subsidiaries are in good condition, free from any
         defects that would materially interfere with the continued use
         thereof in the conduct of their normal operations; and (iv) CBI
         and its Subsidiaries own or lease all property upon which their
         continued business operations are materially dependent (except
         for properties securing loans by CBI).


                                    ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF BANCORP

                   Except as set forth in the disclosure schedule of
         Bancorp delivered to CBI concurrently herewith (the "Bancorp
         Disclosure Schedule"), Bancorp hereby represents and warrants
         to CBI as follows:

                   4.1.  Corporate Organization.  (a)  Bancorp is a cor-
         poration duly organized, validly existing under the laws of the
         State of Oregon.  Bancorp has the corporate power and authority
         to own or lease all of its properties and assets and to carry
         on its business as it is now being conducted, and is duly li-
         censed or qualified to do business in each jurisdiction in
         which the nature of the business conducted by it or the charac-
         ter or location of the properties and assets owned or leased by
         it makes such licensing or qualification necessary, except
         where the failure to be so licensed or qualified would not have
         a Material Adverse Effect on Bancorp.  Bancorp is duly regis-
         tered as a bank holding company under the BHC Act.  The Ar-
         ticles of Incorporation and Bylaws of Bancorp, copies of which
         have previously been made available to CBI, are true, complete
         and correct copies of such documents as in effect as of the
         date of this Agreement.

                   (b)  Each Bancorp Subsidiary (i) is duly organized
         and validly existing as a bank, corporation or partnership un-
         der the laws of its jurisdiction of organization, (ii) is duly
         qualified to do business and in good standing in all jurisdic-
         tions (whether federal, state, local or foreign) where its own-
         ership or leasing of property or the conduct of its business
         requires it to be so qualified and in which the failure to be
         so qualified would have a Material Adverse Effect on Bancorp,
         and (iii) has all requisite corporate power and authority to
         own or lease its properties and assets and to carry on its
         business as now conducted.

                   (c)  The minute books of Bancorp accurately reflect
         in all material respects all corporate actions since January 1,
         1994, of its shareholders and Board of Directors (including
         committees of the Board of Directors of Bancorp).

                   4.2.  Capitalization.  (a)  The authorized capital
         stock of Bancorp consists of (i) 250,000,000 shares of Bancorp
         Common Stock, of which as of December 31, 1995, 150,592,468
         shares were issued and outstanding and (ii) 50,000,000 shares
         of Preferred Stock, no par value ("Bancorp Preferred Stock"),
         of which as of December 31, 1995, 6,000,000 shares designated
         as Series A were issued and outstanding.  All of the issued and
         outstanding shares of Bancorp Common Stock and Bancorp Pre-
         ferred Stock have been duly authorized and validly issued and
         are fully paid, nonassessable and free of preemptive rights,
         with no personal liability attaching to the ownership thereof.
         As of the date of this Agreement, except for shares of Bancorp
         Common Stock reserved for issuance pursuant to the Bancorp Ben-
         efit Plans (as defined below), and (iii) Bancorp's dividend
         reinvestment and stock purchase plan (the "Bancorp DRIP"), Ban-
         corp does not have and is not bound by any outstanding sub-
         scriptions, options, warrants, calls, commitments or agreements
         of any character calling for the purchase or issuance of any
         shares of Bancorp Common Stock or Bancorp Preferred Stock or
         any other equity securities of Bancorp or any securities repre-
         senting the right to purchase or otherwise receive any shares
         of Bancorp Common Stock or Bancorp Preferred Stock.  As of De-
         cember 31, 1995, 12,277,723 shares of Bancorp Common Stock were
         reserved for issuance pursuant to the Bancorp DRIP and Bancorp
         Benefit Plans and no shares of Bancorp Preferred Stock were
         reserved for issuance.  As of the date of this Agreement, since
         December 31, 1995, Bancorp has not issued any shares of its
         capital stock or any securities convertible into or exercisable
         for any shares of its capital stock, other than pursuant to (i)
         the exercise of employee stock options granted prior to such
         date, (ii) the Bancorp Option Agreement, (iii) the Bancorp
         DRIP, (iv) the Bancorp Employee Investment Plan, and (v) the
         grant of options to non-employee directors.  The Shares of Ban-
         corp Capital Stock to be issued pursuant to the Merger will be
         duly authorized and validly issued and, at the Effective Time,
         all such shares will be fully paid, nonassessable and free of
         preemptive rights, with no personal liability attaching to the
         ownership thereof.

                   (b)  Bancorp owns, directly or indirectly, all of the
         issued and outstanding shares of capital stock of each of the
         Bancorp Subsidiaries, free and clear of any liens, charges,
         encumbrances and security interests whatsoever, and all of such
         shares are duly authorized and validly issued and are fully 




                                       -23-<PAGE>







         paid, nonassessable and free of preemptive rights, with no per-
         sonal liability attaching to the ownership thereof.  No Bancorp
         Subsidiary has or is bound by any outstanding subscriptions,
         options, warrants, calls, commitments or agreements of any
         character calling for the purchase or issuance of any shares of
         capital stock or any other equity security of such Subsidiary
         or any securities representing the right to purchase or other-
         wise receive any shares of capital stock or any other equity
         security of such Subsidiary.

                   4.3.  Authority; No Violation.  (a)  Bancorp has full
         corporate power and authority to execute and deliver this
         Agreement and to consummate the transactions contemplated
         hereby.  The execution and delivery of this Agreement and the
         consummation of the transactions contemplated hereby have been
         duly and validly approved by the Board of Directors of Bancorp
         and no other corporate proceedings on the part of Bancorp are
         necessary to approve this Agreement and to consummate the
         transactions contemplated hereby.  This Agreement has been duly
         and validly executed and delivered by Bancorp and (assuming due
         authorization, execution and delivery by CBI) constitutes a
         valid and binding obligation of Bancorp, enforceable against
         Bancorp in accordance with its terms, except as enforcement may
         be limited by general principles of equity whether applied in a
         court of law or a court of equity and by bankruptcy, insolvency
         and similar laws affecting creditors' rights and remedies gen-
         erally.

                   (b)  Neither the execution and delivery of this
         Agreement by Bancorp, nor the consummation by Bancorp of the
         transactions contemplated hereby, nor compliance by Bancorp
         with any of the terms or provisions hereof, will (i) violate
         any provisions of the Articles of Incorporation or Bylaws of
         Bancorp or (ii) assuming that the consents and approvals re-
         ferred to in Section 4.4 are duly obtained, (x) violate any
         statute, code, ordinance, rule, regulation, judgment, order,
         writ, decree or injunction applicable to Bancorp or any of its
         Subsidiaries or any of their respective properties or assets,
         or (y) violate, conflict with, result in a breach of any provi-
         sion of or the loss of any benefit under, constitute a default
         (or an event which, with notice or lapse of time, or both,
         would constitute a default) under, result in the termination of
         or a right of termination or cancellation under, accelerate the
         performance required by, or result in the creation of any lien,
         pledge, security interest, charge or other encumbrance upon any
         of the respective properties or assets of Bancorp or any of its
         Subsidiaries under, any of the terms, conditions or provisions
         of any note, bond, mortgage, indenture, deed of trust, license,
         lease, agreement or other instrument or obligation to which
         Bancorp or any of its Subsidiaries is a party, or by which they 



                                       24-<PAGE>







         or any of their respective properties or assets may be bound or
         affected, except (in the case of clause (y) above) for such
         violations, conflicts, breaches or defaults which either indi-
         vidually or in the aggregate will not have or be reasonably
         likely to have a Material Adverse Effect on Bancorp.

                   4.4.  Consents and Approvals.  Except for (i) the
         filing of applications and notices, as applicable, with the
         Federal Reserve Board under the BHC Act, (ii) the filing of any
         requisite applications with the OCC or the FDIC in connection
         with the merger of Subsidiaries of CBI and Bancorp, (iii) the
         filing of the State Approvals, (iv) the filing with the SEC of

         the filing of the Certificate of Merger with the Delaware Sec-
         retary pursuant to the DGCL, (vii) such filings and approvals
         as are required to be made or obtained under the securities or
         "Blue Sky" laws of various states in connection with the issu-
         ance of the shares of Bancorp Common Stock pursuant to this
         Agreement, and (viii) the approval of this Agreement by the
         requisite vote of the shareholders of CBI, no consents or ap-
         provals of or filings or registrations with any Governmental
         Entity or with any third party are necessary in connection with
         (A) the execution and delivery by Bancorp of this Agreement and
         (B) the consummation by Bancorp of the Merger and the other
         transactions contemplated hereby.

                   4.5.  Reports.  Bancorp and each of its Subsidiaries
         have timely and properly filed all material reports, registra-
         tions and statements, together with any amendments required to
         be made with respect thereto, that they were required to file
         since January 1, 1994, with the Regulatory Agencies, and all
         other material reports and statements required to be filed by
         them since January 1, 1994, and have paid all fees and assess-
         ments due and payable in connection therewith.  Except for nor-
         mal examinations conducted by a Regulatory Agency in the regu-
         lar course of the business of Bancorp and its Subsidiaries, no
         Regulatory Agency has initiated any proceeding or, to the best
         knowledge of Bancorp, investigation into the business or opera-
         tions of Bancorp or any of its Subsidiaries since January 1,
         1994.  There is no material unresolved violation, criticism, or
         exception by any Regulatory Agency with respect to any report
         or statement relating to any examinations of Bancorp or any of
         its Subsidiaries.

                   4.6.  Financial Statements.  Bancorp has previously
         delivered to CBI copies of (a) the consolidated balance sheets
         of Bancorp and is Subsidiaries as of December 31, for the fis-
         cal years 1993 and 1994, and the related consolidated state-
         ments of income, changes in shareholders' equity and cash flows 



                                       -25-<PAGE>







         for the fiscal years 1992 through 1994, inclusive, as reported
         in Bancorp's Annual Report on Form 10-K for the fiscal year
         ended December 31, 1994, filed with the SEC under the Exchange
         Act, in each case accompanied by the audit report of Deloitte &
         Touche LLP, independent auditors with respect to Bancorp, (b)
         the unaudited consolidated balance sheet of Bancorp and its
         subsidiaries as of December 31, 1995, and the related consoli-
         dated statements of income, cash flows and changes in share-
         holders' equity for the fiscal year ended December 31, 1995,
         substantially in the form that is proposed to be reported in
         Bancorp's Annual Report on Form 10-K for the fiscal year ended
         December 31, 1995, filed with the SEC under the Exchange Act,
         and (c) the unaudited consolidated balance sheets of Bancorp
         and its Subsidiaries as of September 30, 1995, and September
         30, 1994, and the related unaudited consolidated statements of
         income, cash flows and changes in shareholders' equity for the
         nine months then ended as reported in Bancorp's Quarterly Re-
         port on Form 10-Q for the period ended September 30, 1995,
         filed with the SEC under the Exchange Act.  The financial
         statements referred to in this Section 4.6 (including the re-
         lated notes, where applicable) fairly present (subject, in the
         case of the unaudited statements, to recurring audit adjust-
         ments normal in nature and amount), the results of the consoli-
         dated operations and changes in shareholders' equity and con-
         solidated financial position of Bancorp and its Subsidiaries
         for the respective fiscal periods or as of the respective dates
         therein set forth; each of such statements (including the re-
         lated notes, where applicable) complies in all material re-
         spects with applicable accounting requirements and with the
         published rules and regulations of the SEC with respect
         thereto, and each of such statements (including the related
         notes, where applicable) has been prepared in accordance with
         GAAP consistently applied during the periods involved, except
         in each case as indicated in such statements or in the notes
         thereto or, in the case of unaudited statements, as permitted
         by Form 10-Q.  The allowances for credit losses contained in
         the financial statements referred to in this Section 4.6 were
         adequate as of their respective dates to absorb reasonably an-
         ticipated losses in the loan portfolio of Bancorp and its Sub-
         sidiaries in view of the size and character of such portfolio,
         the current economic conditions, and other pertinent factors
         and no facts have subsequently come to the attention of manage-
         ment of Bancorp that would cause management to restate in any
         material way the level of such allowance for credit losses.
         With respect to other real estate owned by Bancorp and its Sub-
         sidiaries, the value attributed thereto for purposes of compil-
         ing such financial statements does not exceed the aggregate
         fair market value of such real estate as of the date of acqui-
         sition of such real estate or as subsequently reduced, all in 




                                       -26-<PAGE>







         accordance with regulations of the applicable Regulatory Agen-
         cies.  The books and records of Bancorp and its Subsidiaries
         have been, and are being, maintained in all material respects
         in accordance with GAAP and any other applicable legal and ac-
         counting requirements and reflect only actual transactions.

                   4.7.  Brokers' Fees.  Neither Bancorp nor any Bancorp
         Subsidiary nor any of their respective officers or directors
         has employed any broker or finder or incurred any liability for
         any broker's fees, commissions or finder's fees in connection
         with any of the transactions contemplated by this Agreement or
         the CBI Option Agreement.

                   4.8.  Absence of Certain Changes or Events.  (a)  Ex-
         cept as publicly disclosed in Bancorp Reports (as defined be-
         low) filed prior to the date hereof, since December 31, 1994,
         (i) as of the date of this Agreement, neither Bancorp nor any
         of its Subsidiaries has incurred any material liability, except
         in the ordinary course of their business consistent with their
         past practices, and (ii) no event has occurred that has had, or
         is reasonably likely to have, individually or in the aggregate,
         a Material Adverse Effect on Bancorp.

                   (b)  Except as publicly disclosed in Bancorp Reports
         filed prior to the date hereof, from December 31, 1994, through
         the date of this Agreement, Bancorp and its Subsidiaries have
         carried on their respective businesses in the ordinary and
         usual course consistent with their past practices.

                   (c)  Since January 1, 1995, neither Bancorp nor any
         of its Subsidiaries has (i) suffered any strike, work stoppage,
         slowdown, or other labor disturbance or (ii) been the subject
         of any organizing activities.

                   4.9.  Legal Proceedings.  (a)  Except as publicly
         disclosed in Bancorp Reports filed prior to the date hereof,
         neither Bancorp nor any of its Subsidiaries is a party to any
         and there are no pending or, to the best of Bancorp's knowl-
         edge, threatened, material legal, administrative, arbitral or
         other proceedings, claims, actions or governmental or regu-
         latory investigations of any nature (i) against Bancorp or any
         of its Subsidiaries as to which there is a reasonable possibil-
         ity of an adverse determination and which, if adversely deter-
         mined, would, individually or in the aggregate, have a Material
         Adverse Effect on Bancorp or (ii) challenging the validity or
         propriety of the transactions contemplated by this Agreement.

                   (b)  There is no injunction, order, judgment, decree,
         or regulatory restriction imposed upon Bancorp, any of its Sub-
         sidiaries or the assets of Bancorp or any of its Subsidiaries 



                                       -27-<PAGE>







         that has had, or might reasonably be expected to have, a Mate-
         rial Adverse Effect on Bancorp or the Surviving Corporation.

                   4.10.  Taxes and Tax Returns.  (a)  Each of Bancorp
         and its Subsidiaries has duty filed all material federal, state
         and, to the best of Bancorp's knowledge, material local infor-
         mation returns and tax returns required to be filed by it on or
         prior to the date hereof (all such returns being accurate and
         complete in all material respects) and has duly paid or made
         provisions for the payment of all material Taxes (as defined
         below) and other governmental charges which have been incurred
         or are due or claimed to be due from it by federal, state,
         county or local taxing authorities on or prior to the date of
         this Agreement (including, without limitation, if and to the
         extent applicable, those due in respect of its properties, in-
         come, business, capital stock, deposits, franchises, licenses,
         sales and payrolls) other than Taxes or other charges (1) that
         are not yet delinquent or are being contested in good faith and
         (2) have not been finally determined.  The income tax returns
         of Bancorp and its Subsidiaries have been examined by the In-
         ternal Revenue Service (the "IRS") and any liability with re-
         spect thereto has been satisfied for all years to and including
         1985, and no material deficiencies were asserted as a result of
         such examination or all such deficiencies were satisfied.  To
         the best of Bancorp's knowledge, there are no material disputes
         pending, or claims asserted for, Taxes or assessments upon Ban-
         corp or any of its Subsidiaries, nor has Bancorp or any of its
         Subsidiaries been requested to give any currently effective
         waivers extending the statutory period of limitation applicable
         to any federal, state, county or local income tax return for
         any period.  In addition, (i) proper and accurate amounts have
         been withheld by Bancorp and its Subsidiaries from their em-
         ployees for all prior periods in compliance in all material
         respects with the tax withholding provisions of applicable fed-
         eral, state and local laws, except where failure to do so would
         not have a Material Adverse Effect on Bancorp, (ii) federal,
         state, county and local returns that are accurate and complete
         in all material respects have been filed by Bancorp and its
         Subsidiaries for all periods for which returns were due with
         respect to income tax withholding, Social Security and unem-
         ployment taxes, except where failure to do so would not have a
         Material Adverse Effect on Bancorp, (iii) the amounts shown on
         such federal, state, local or county returns to be due and pay-
         able have been paid in full or adequate provision therefor has
         been included by Bancorp in its consolidated financial state-
         ments as of December 31, 1995, except where failure to do so
         would not have a Material Adverse Effect on Bancorp and (iv)
         there are no Tax liens upon any property or assets of the Ban-
         corp or its Subsidiaries except liens for current taxes not yet
         due.  To the knowledge of Bancorp, no property of Bancorp or 



                                       -28-<PAGE>







         any of its Subsidiaries is property that Bancorp or any of its
         Subsidiaries is or will be required to treat as being owned by
         another person pursuant to the provisions of Section 168(f)(8)
         of the Code (as in effect prior to its amendment by the Tax
         Reform Act of 1986) or is "tax-exempt use property" within the
         meaning of Section 169(h) of the Code.  Neither Bancorp nor any
         of its Subsidiaries has been required to include in income any
         adjustment pursuant to Section 481 of the Code by reason of a
         voluntary change in accounting method initiated by Bancorp or
         any of its Subsidiaries, and the Internal Revenue Service has
         not initiated or proposed any such adjustment or change in ac-
         counting method.  Except as set forth in the financial state-
         ments described in Section 4.6 hereof, neither Bancorp nor any
         of its Subsidiaries has entered into a transaction which is
         being accounted for as an installment obligation under Section
         453 of the Code, which would be reasonably likely to have a
         Material Adverse Effect on Bancorp.

                   (b)  Any amount that could be received (whether in
         cash or property or the vesting of property) as a result of any
         of the transactions contemplated by this Agreement by any em-
         ployee, officer or director of Bancorp or any of its affiliates
         who is a "Disqualified Individual" (as such term is defined in
         proposed Treasury Regulation Section 1.280G-1) under any em-
         ployment, severance or termination agreement, other compensa-
         tion arrangement or Bancorp Benefit Plan currently in effect
         would not be characterized as an "excess parachute payment" (as
         such term is defined in Section 280G(b)(1) of the Code).

                   (c)  No disallowance of a deduction under Section
         162(m) of the Code for employee remuneration of any amount paid
         or payable by Bancorp or any Subsidiary of Bancorp under any
         contract, plan, program, arrangement or understanding is rea-
         sonably likely.

                   4.11.  Employees.  (a)  The Bancorp Disclosure Sched-
         ule sets forth a true and complete list of each material plan,
         arrangement or agreement regarding compensation or benefits for
         any employees, former employees, directors, or former directors
         that is maintained as of the date of this Agreement (the "Ban-
         corp Benefit Plans") by Bancorp, any of its Subsidiaries or by
         any trade or business; whether or not incorporated (a "Bancorp
         ERISA Affiliate"), all of which together with Bancorp would be
         deemed a "single employer" within the meaning of Section 4001
         of ERISA.

                   (b)  Bancorp has heretofore delivered to CBI true and
         complete copies of each of the Bancorp Benefit Plans and all
         related documents, including but not limited to (i) the actu-
         arial report for such Bancorp Benefit Plan (if applicable) for 



                                       -29-<PAGE>







         each of the last two years, and (ii) the most recent deter-
         mination letter from the Internal Revenue Service (if applica-
         ble) for such Bancorp Benefit Plan.

         operated and administered in all material respects in compli-
         ance with applicable laws, including but not limited to ERISA
         and the Code, (ii) each of the Bancorp Benefit Plans intended
         to be "qualified" within the meaning of Section 401(a) of the
         Code is so qualified, (iii) with respect to each Bancorp Ben-
         efit Plan that is subject to Title IV of ERISA, the present
         value of accrued benefits under such Bancorp Benefit Plan based
         upon the actuarial assumptions used for funding purposes in the
         most recent actuarial report prepared by such Bancorp Benefit
         Plan's actuary with respect to such Bancorp Benefit Plan, did
         not, as of its latest valuation date, exceed the then current
         value of the assets of such Bancorp Benefit Plan allocable to
         such accrued benefits, (iv) no Bancorp Benefit Plan provides
         benefits, including without limitation death or medical ben-
         efits (whether or not insured), with respect to current or
         former employees of Bancorp, its Subsidiaries or any Bancorp
         ERISA beyond their retirement or other termination of service,
         other than (w) coverage mandated by applicable law, (x) death
         benefits or retirement benefits under any "employee pension
         plan," as that term is defined in Section 3(2) of ERISA, (y)
         deferred compensation benefits accrued as liabilities on the
         books of Bancorp, its Subsidiaries or the Bancorp ERISA Affili-
         ates or (z) benefits the full cost of which is borne by the
         current or former employee (or his beneficiary), (v) no li-
         ability under Title IV of ERISA has been incurred by Bancorp,
         its Subsidiaries or any Bancorp ERISA Affiliate that has not
         been satisfied in full, and no condition exists that presents a
         material risk to Bancorp, its Subsidiaries or any Bancorp ERISA
         Affiliate of incurring a material liability thereunder, (vi) no
         Bancorp Benefit Plan is a "multiemployer pension plan," as such
         term is defined in Section 3(37) of ERISA, (vii) all contribu-
         tions or other amounts payable by Bancorp or its Subsidiaries
         as of the Effective Time with respect to each Bancorp Benefit
         Plan in respect of current or prior plan years have been paid
         or accrued in accordance with GAAP and Section 412 of the Code,
         (viii) neither Bancorp, its Subsidiaries nor any Bancorp ERISA
         Affiliate has engaged in a transaction in connection with which
         Bancorp, its Subsidiaries or any Bancorp ERISA Affiliate could
         be subject to either a material civil penalty assessed pursuant
         to Section 409 or 502(i) of ERISA or a material tax imposed
         pursuant to Section 4975 or 4976 of the Code, and (ix) to the
         best knowledge of Bancorp there are no pending, threatened or
         anticipated claims (other than routine claims for benefits) by,
         on behalf of or against any of the Bancorp Benefit Plans or any
         trusts related thereto.

                   (d)  Neither the execution and delivery of this
         Agreement nor the consummation of the transactions contemplated
         hereby will (i) result in any material payment (including,
         without limitation, severance, unemployment compensation,
         golden parachute or otherwise) becoming due to any director or
         any employee of Bancorp or any of its affiliates from Bancorp
         or any of its affiliates under any Bancorp Benefit Plan or oth-
         erwise, (ii) materially increase any benefits otherwise payable
         under any Bancorp Benefit Plan, or (iii) result in any ac-
         celeration of the time of payment or vesting of any such ben-
         efits to any material extent.

                   4.12.  SEC Reports.  Bancorp has previously made
         available to CBI an accurate and complete copy of each (a) fi-
         nal registration statement, prospectus, report, schedule and
         definitive proxy statement filed since January 1, 1994, by Ban-
         corp with the SEC pursuant to the Securities Act or the Ex-
         change Act (the "Bancorp Reports") and prior to the date hereof
         and (b) communication mailed by Bancorp to its shareholders
         since January 1, 1994, and prior to the date hereof, and no
         such registration statement, prospectus, report, schedule,
         proxy statement or communication contained any untrue statement
         of a material fact or omitted to state any material fact re-
         quired to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which
         they were made, not misleading, except that information as of a
         later date shall be deemed to modify information as of an ear-
         lier date.  Bancorp has timely filed all Bancorp Reports and
         other documents required to be filed by it under the Securities
         Act and the Exchange Act, and, as of their respective dates,
         all Bancorp Reports complied in all material respects with the
         published rules and regulations of the SEC with respect
         thereto.

                   4.13.  Compliance with Applicable Law.  (a)  Bancorp
         and each of its Subsidiaries hold, and have at all times held,
         all material licenses, franchises, permits and authorizations
         necessary for the lawful conduct of their respective businesses
         under and pursuant to all, and have complied with and are not
         in default in any material respect under any, applicable laws,
         statutes, orders, rules, or regulations of any Governmental
         Entity relating to Bancorp or any of its Subsidiaries, except
         where the failure to hold such license, franchise, permit or
         authorization or such noncompliance or default would not, indi-
         vidually or in the aggregate, have a Material Adverse Effect on
         Bancorp, and neither Bancorp nor any of its Subsidiaries knows
         of, or has received notice of, any material violations of any
         of the above.





                                       -31-<PAGE>







                   (b)  Except as would not have a Material Adverse Ef-
         fect, (i) no real property presently or previously owned, oper-
         ated, or leased by Bancorp or any of its Subsidiaries or, to
         the best of their knowledge, securing any obligations owed to
         them has been used as a storage or disposal site for hazardous
         substances within the meaning of any applicable federal, state,
         or local statute, law, rule, or regulation, and no hazardous
         substances have been transferred from or to such real property,
         (ii) no governmental entity has issued any citation or notice
         of violation relating to any environmental matter concerning
         any real property owned, operated, or leased by Bancorp or any
         of its Subsidiaries or, to the best of their knowledge securing
         any obligations owed to them, and neither Bancorp nor any of
         its Subsidiaries has received any notice that any such real
         property may or will be included on any list of areas affected
         by any release of any hazardous substance or that it has or may
         be named as a responsible or potentially responsible party with
         respect to any hazardous substance site, and (iii) neither Ban-
         corp nor any of its Subsidiaries has received any notice of any
         threatened investigation, proceeding, or litigation concerning
         any such real property with aspect to any environmental matter
         or knows of any basis for any such investigation, proceeding,
         or litigation.

                   4.14.  Certain Contracts.  (a)  As of the date of
         this Agreement, neither Bancorp nor any of its Subsidiaries is
         a party to or bound by any contact, arrangement, commitment or
         understanding (whether written or oral) (i) with respect to the
         employment of any directors, officers, employees or consult-
         ants, (ii) that, upon the consummation of the transactions con-
         templated by this Agreement will (either alone or upon the oc-
         currence of any additional acts or events) result in any pay-
         ment (whether of severance pay or otherwise) becoming due from
         Bancorp, CBI, the surviving Corporation, or any of their re-
         spective Subsidiaries to any officer or employee thereof, (iii)
         that is a material contract (as defined in Item 601(b)(10) of
         Regulation S-K of the SEC) to be performed after the date of
         this Agreement that has not been filed or incorporated by ref-
         erence in the Bancorp Reports, (iv) that materially restricts
         the conduct of any line of business by Bancorp, (v) with or to
         a labor union or guild (including any collective bargaining
         agreement), or (vi) (including any stock option plan, stock
         appreciation rights plan, restricted stock plan or stock pur-
         chase plan) any of the benefits of which will be increased, or
         the vesting of the benefits of which will be accelerated, by
         the occurrence of any of the transactions contemplated by this
         Agreement, or the value of any of the benefits of which will be
         calculated on the basis of any of the transactions contemplated
         by the Agreement.  Each contract, arrangement, commitment or
         understanding of the type described in this Section 4.14(a), 



                                       -32-<PAGE>







         whether or not set forth in the Bancorp Disclosure Schedule, is
         referred to herein as a "Bancorp Contract."  Neither Bancorp
         nor any of its Subsidiaries knows of, or has received notice
         of, any violation of any violation of any Bancorp Contract by
         any of the other parties thereto that, individually or in the
         aggregate, would have a Material Adverse Effect on Bancorp.

                   (b)  (i)  Each Bancorp Contract is valid and binding
         and in full force and effect, (ii) Bancorp and each of its Sub-
         sidiaries has in all material respects performed all obliga-
         tions required to be performed by it to date under each Bancorp
         Contract, except where such noncompliance, individually or in
         the aggregate, would not have a Material Adverse Effect on Ban-
         corp, and (iii) no event or condition exists that constitutes
         or, after notice, or lapse of time, or both, would constitute,
         a material default on the part of Bancorp or any of its Subsid-
         iaries or, to the knowledge of Bancorp, on the part of any
         other party under any such Bancorp Contract, except where such
         default, individually or in the aggregate, would not have a
         Material Adverse Effect on Bancorp.

                   4.15.  Agreements with Regulatory Agencies.  Neither
         Bancorp nor any of its Subsidiaries is subject to any cease-
         and-desist or other order issued by, or is a party to any writ-
         ten agreement, consent agreement or memorandum of understanding
         with, or is a party to any commitment letter or similar under-
         taking to, or is subject to any order or directive by, or is a
         recipient of any supervisory letter from, or has adopted any
         board resolutions at the request of (each, whether or not set
         forth in the Bancorp Disclosure Schedule, a "Bancorp Regulatory
         Agreement"), any Regulatory Agency or other Governmental Entity
         that restricts the conduct of its business or that in any man-
         ner relates to its capital adequacy, its credit policies, its
         management or its business, nor has Bancorp or any of its Sub-
         sidiaries been advised by any Regulatory Agency or other Gov-
         ernmental Entity that it is considering issuing or requesting
         any Regulatory Agreement.

                   4.16.  Undisclosed Liabilities.  As of the date of
         this Agreement, except for those liabilities that are fully
         reflected or reserved against on the consolidated balance sheet
         of Bancorp dated as of December 31, 1995, and for liabilities
         incurred in the ordinary course of business consistent with
         past practice, since December 31, 1995, neither Bancorp nor any
         of its Subsidiaries has incurred any liability of any nature
         whatsoever (whether absolute, accrued, contingent or otherwise
         and whether due or to become due) that, either alone or when
         combined with all similar liabilities, has had, or could rea-
         sonably be expected to have, a Material Adverse Effect on Ban-
         corp.



                                       -33-<PAGE>







                   4.17.  Pooling of Interests.  As of date of this
         Agreement, Bancorp has no reason to believe that the Merger
         will not qualify as a pooling of interests for accounting pur-
         poses.

                   4.18.  Interest Rate Risk Management Instruments; De-
         rivatives.  (a)  Bancorp has heretofore delivered to CBI an
         accurate and complete list of all Derivative Securities to
         which Bancorp or any of its Subsidiaries is a party or any of
         their properties may be subject, or that are owned by Bancorp
         or any of its Subsidiaries.  Neither Bancorp nor any of its
         Subsidiaries has purchased any Derivative Security for, or in-
         vested in any Derivative Security any assets of, any account or
         person for which it or any such Subsidiary acts as a trustee,
         fiduciary, or investment advisor.

                   (b)  All Derivative Securities to which Bancorp or
         any of its Subsidiaries is a party or to which any of their
         properties or assets may be subject were entered into in the
         ordinary course of business and, to its knowledge, in ac-
         cordance with prudent banking practice and applicable rules,
         regulations, and policies of the Regulatory Agencies and with
         counterparties believed to be financially responsible at the
         time and are legal, valid, and binding obligations enforceable
         in accordance with their terms (except as may be limited by
         bankruptcy, insolvency, moratorium, reorganization, or similar
         laws affecting the rights of creditors generally, and the
         availability of equitable remedies), and are in full force and
         effect.  Bancorp and each of its Subsidiaries has duly per-
         formed in all material respects all of its obligations thereun-
         der, and, to its knowledge, there are no breaches, violations,
         or defaults or allegations or assertions of such by any party
         thereunder.

                   4.19.  State Takeover Laws.  The Board of Directors
         of Bancorp has taken such actions as are necessary such that
         the provisions of Sections 60.825 to 60.845 of the Oregon Busi-
         ness Corporation Act regarding business combinations and the
         Oregon Control Share Act (Sections 60.801 to 60.813) will not
         apply to this Agreement or to any of the transactions contem-
         plated hereby or thereby.

         templated hereby or to perform its covenants and agreements

         expressly contemplated or permitted by this Agreement, Bancorp

              meaning of Section 368 of the Code; provided, however,
              that nothing contained herein shall limit the ability of
              Bancorp to exercise its rights under the CBI Option Agree-
              ment;

                   (c)  take any action that is intended or may reason-

                              ADDITIONAL AGREEMENTS

                   6.1. Regulatory Matters.  (a)  Bancorp and CBI shall
         promptly prepare and file with the SEC the Proxy Statement and
         Bancorp shall promptly prepare and file with the SEC the S-4,
         in which the Proxy Statement will be included as a prospectus.
         Each of Bancorp and CBI shall use all reasonable efforts to
         have the S-4 declared effective under the Securities Act as
         promptly as practicable after such filing, and Bancorp and CBI
         shall thereafter mail the Proxy Statement to their respective
         shareholders.  Bancorp shall also use all reasonable efforts to
         obtain all necessary state securities law or "Blue Sky" permits
         and approvals required to carry out the transactions contem-
         plated by this Agreement, and CBI shall furnish all information
         concerning CBI and the holders of CBI Common Stock as may be
         reasonably requested in connection with any such action.

                   (b)  The parties hereto shall cooperate with each
         other and use their reasonable best efforts to promptly prepare
         and file all necessary documentation, to effect all applica-
         tions, notices, petitions and filings, to obtain as promptly as
         practicable all permits, consents, approvals and authorizations
         of all third parties and Governmental Entities which are neces-
         sary or advisable to consummate the transactions contemplated
         by this Agreement (including, without limitation, the Merger),
         and to comply with the terms and conditions of all such per-
         mits, consents, approvals and authorizations of all such Gov-
         ernmental Entities.  Bancorp and CBI shall have the right to
         review in advance, and to the extent practicable each will con-
         sult the other on, in each case subject to applicable laws re-
         lating to the exchange of information, all the information re-
         lating to CBI or Bancorp, as the case may be, and any of their
         respective Subsidiaries, which appear in any filing made with,
         or written materials submitted to, any third party or any Gov-
         ernmental Entity in connection with the transactions contem-
         plated by this Agreement.  In exercising the foregoing right,
         each of the parties hereto shall act reasonably and as promptly
         as practicable.  The parties hereto agree that they will con-
         sult with each other with respect to the obtaining of all per-
         mits, consents, approvals and authorizations of all third par-
         ties and Governmental Entities necessary or advisable to con-
         summate the transactions contemplated by this Agreement and
         each party will keep the other apprised of the status of mat-
         ters relating to completion of the transactions contemplated
         herein.

                   (c)  Bancorp and CBI shall, upon request, furnish
         each other with all information concerning themselves, their
         Subsidiaries, directors, officers and shareholders and such 



                                       -39-<PAGE>







         other matters as may be reasonably necessary or advisable in
         connection with the Proxy Statement, the S-4 or any other
         statement, filing, notice or application made by or on behalf
         of Bancorp, CBI or any of their respective Subsidiaries to any
         Governmental Entity in connection with the Merger and the other
         transactions contemplated by this Agreement.

                   (d)  Bancorp and CBI shall promptly advise each other
         upon receiving any communication from any Governmental Entity
         whose consent or approval is required for consummation of the
         transactions contemplated by this Agreement which causes such
         party to believe that there is a reasonable likelihood that any
         Requisite Regulatory Approval will not be obtained or that the
         receipt of any such approval will be materially delayed.

                   6.2. Access to Information.  (a)  Upon reasonable
         notice and subject to applicable laws relating to the exchange
         of information, each of Bancorp and CBI shall, and shall cause
         each of their respective Subsidiaries to, afford to the offic-
         ers, employees, accountants, counsel and other representatives
         of the other party, access, during normal business hours during
         the period prior to the Effective Time, to all its proprties,
         books, contracts, commitments and records and, during such pe-
         riod, each of Bancorp and CBI shall, and shall cause their re-
         spective Subsidiaries to, make available to the other party (i)
         a copy of each report, schedule, registration statement and
         other document filed or received by it during such period pur-
         suant to the requirement of federal securities laws or federal
         or state banking laws, savings and loan or savings association
         laws (other than reports or documents which Bancorp or CBI, as
         the case may be, is not permitted to disclose under applicable
         law) and (ii) all other information concerning its business,
         properties and personnel as such party may reasonably request.
         Neither Bancorp nor CBI nor any of their respective Subsidiar-
         ies shall be required to provide access to or to disclose in-
         formation where such access or disclosure would violate or
         prejudice the rights of Bancorp's or CBI's, as the case may be,
         customers, jeopardize the attorney-client privilege of the in-
         stitution in possession or control of such information or con-
         travene any law, rule, regulation, order, judgment, decree,
         fiduciary duty or binding agreement entered into prior to the
         date of this Agreement.  The parties hereto will make appropri-
         ate substitute disclosure arrangements under circumstances in
         which the restrictions of the preceding sentence apply.

                   (b)  Each of Bancorp and CBI shall hold all informa-
         tion furnished by the other party or any of such party's Sub-
         sidiaries or representatives pursuant to Section 6.2(a) in con-
         fidence to the extent required by, and in accordance with, the
         provisions of the confidentiality agreements, dated December 



                                       -40-<PAGE>







         13, 1995, between Bancorp and CBI (the "Confidentiality Agree-
         ments").

                   (c)  No investigation by either of the parties or
         their respective representatives shall affect the representa-
         tions and warranties of the other set forth herein.

                   6.3. Shareholder Approval.  CBI shall call a meeting
         of its shareholders to be held as soon as practicable for the
         purpose of voting upon the requisite shareholder approval re-
         quired in connection with this Agreement and the Merger.  Sub-
         ject to fiduciary requirements under applicable law, the board
         of directors of CBI shall recommend such approval to its share-
         holders and shall use reasonable efforts to solicit such ap-
         proval.

                   6.4. Legal Conditions to Merger.  Each of Bancorp and
         CBI shall, and shall cause its Subsidiaries to, use their rea-
         sonable best efforts (a) to take, or cause to be taken, all
         actions necessary, proper, or advisable to comply promptly with
         all legal requirements which may be imposed on such party or
         its Subsidiaries with respect to the Merger or the Subsidiary
         Merger and, subject to the conditions set forth in Article VII
         hereof, to consummate the transactions contemplated by this
         Agreement and (b) to obtain (and to cooperate with the other
         party to obtain) any consent, authorization, order or approval
         of, or any exemption by, any Governmental Entity and any other
         third party which is required to be obtained by CBI or Bancorp
         or any of their respective Subsidiaries in connection with the
         Merger and the Subsidiary Merger and the other transactions
         contemplated by this Agreement.

                   6.5. Affiliates; Publication of Combined Financial
         Results.  (a)  Each of Bancorp and CBI shall use its best ef-
         forts to cause each director, executive officer and other per-
         son who is an "affiliate" (for purposes of Rule 145 under the
         Securities Act and for purposes of qualifying the Merger for
         "pooling-of-interests" accounting treatment) of such party to
         deliver to the other party hereto, as soon as practicable after
         the date of this Agreement, and prior to the date of the share-
         holder meeting called by CBI to approve this Agreement, a writ-
         ten agreement, in the form of Exhibit 6.5(a) hereto, providing
         that such person will not sell, pledge, transfer or otherwise
         dispose of any shares of Bancorp Common Stock or CBI Common
         Stock held by such "affiliate" and, in the case of the "affili-
         ates" of CBI, the shares of Bancorp Common Stock to be received
         by such "affiliate" in the Merger:  (1) in the case of shares
         of Bancorp Common Stock to be received by "affiliates" of CBI
         in the Merger, except in compliance with the applicable provi-
         sions of the Securities Act and the rules and regulations 



                                       -41-<PAGE>







         thereunder; and (2) during the period commencing 30 days prior
         to the Merger and ending at the time of the publication of fi-
         nancial results covering at least 30 days of combined opera-
         tions of Bancorp and CBI.  Notwithstanding any other provision
         of this Agreement, no certificate for Bancorp Common Stock
         shall be delivered in exchange for CBI Certificates held by any
         such "affiliate" who shall not have executed and delivered such
         an agreement.

                   (b)  Bancorp shall use its best efforts to publish no
         later than ninety (90) days after the end of the first month
         after the Effective Time in which there are at least thirty
         (30) days of post-Merger combined operations (which month may
         be the month in which the Effective Time occurs), combined
         sales and net income figures as contemplated by and in accor-
         dance with the terms of SEC Accounting Series Release No. 135.

                   6.6. Stock Exchange Listing of Shares.  Bancorp shall
         use its best efforts to cause the shares of Bancorp Common
         Stock to be issued in the Merger to be approved for listing on
         the NASDAQ Stock Market National Market System, subject to of-
         ficial notice of issuance, prior to the Effective Time.

                   6.7. Employee Benefit Plans.  (a)  Within a reason-
         able time after the Effective Time, and subject to applicable
         law, Bancorp shall provide to the employees of Bancorp and its
         Subsidiaries who formerly were employees of CBI and its Subsid-
         iaries employee benefits, including but not limited to pension
         plans, thrift plans, management incentive plans, group life
         plans, accidental death and dismemberment plans, travel ac-
         cident plans, medical and hospitalization plans and long term
         disability plans, substantially the same as those provided to

         plished the actions contemplated by the preceding sentence,
         employees of Bancorp or its Subsidiaries who were employees of
         CBI or its Subsidiaries immediately prior to the Effective Time
         shall be provided with employee benefits under employee benefit
         plans of CBI, employee benefit plans of Bancorp, or some combi-
         nation thereof, as Bancorp shall reasonably deem appropriate in
         order to accomplish an orderly transition of benefits.  From
         and after the Effective Time, employees of Bancorp or its Sub-
         sidiaries who were employees of CBI and its Subsidiaries im-
         mediately prior to the Effective Time shall receive full credit
         for all purposes under such plans, except the accrual of ben-
         efits, for their length of service prior to the Effective Time
         with CBI or any of its Subsidiaries (and any predecessors
         thereto) to the extent such service would be recognized under
         such plans, if such service was with Bancorp and its Subsidiar-
         ies.

                   (b)  Bancorp agrees to honor in accordance with their
         terms (i) all CBI Benefit Plans and (ii) all contracts, ar-
         rangements, commitments, or understandings described in Section
         3.14(a)(i) disclosed on the CBI Disclosure Schedule, and (iii)
         all benefits vested thereunder as of the Effective Time; pro-
         vided, however, that nothing in this sentence shall be inter-
         preted as preventing Bancorp from amending, modifying or termi-
         nating any CBI Benefit Plans, contracts, arrangements, commit-
         ments or understandings, in accordance with their terms.  The
         provisions of this Section 6.7 are intended to be for the ben-
         efit for, and enforceable by, each of the beneficiaries of or
         parties to such plans, contracts, arrangements, commitments,
         and understandings.

                   (c)  CBI shall cause each outstanding option to pur-
         chase CBI Common Stock held by directors or employees of CBI
         and its Subsidiaries (and any related stock appreciation right)
         to be amended at or prior to the Effective Time so that at the
         Effective Time, there shall be exchanged and substituted for
         each such option (or stock appreciation right) an option to
         purchase (or the right to receive appreciation in market value
         of) shares of Bancorp Common Stock, rather than CBI Common
         Stock, in a form substantially as provided in the Bancorp 1993
         Stock Incentive Plan.  The number of shares of Bancorp Common
         Stock covered by the substituted option (and stock appreciation
         right) shall be computed by applying the Exchange Ratio to the
         shares of CBI Common Stock covered by the option (or stock ap-
         preciation right), with any resulting fractional shares to be
         rounded down to the next whole share.  The exercise price per
         share of the substituted option shall be equal to the exercise
         price per share of CBI Common Stock under the original option
         divided by the Exchange Ratio with the result rounded up to the
         next cent.  All such options (and stock appreciation rights)
         shall remain in full force and effect with the same remaining
         term and without any acceleration of exercisability or confer-
         ring any right to receive cash by reason of the Merger, except
         as provided by their terms as in effect prior to the date of
         this Agreement.  Bancorp shall cooperate as necessary to permit
         the taking of the actions specified in this paragraph (c).

                   6.8. Indemnification; Directors' and Officers' Insur-
         ance.  (a)  In the event of any threatened or actual claim,
         action, suit, proceeding or investigation, whether civil, crim-
         inal or administrative, including, without limitation, any such
         claim, action, suit, proceeding or investigation in which any
         person who is now, or has been at any time prior to the date of
         this Agreement, or who becomes prior to the Effective Time, a
         director or officer of CBI or any of its Subsidiaries (the "In-
         demnified Parties") is, or is threatened to be, made a party
         based in whole or in part on, or arising in whole or in part 



                                       -43-<PAGE>







         out of, or pertaining to (i) the fact that he is or was a di-
         rector or officer of CBI, any of the CBI Subsidiaries or any of
         their respective predecessors or (ii) this Agreement, the CBI
         Option Agreement, or any of the transactions contemplated
         hereby or thereby, whether in any case asserted or arising be-
         fore or after the Effective Time, the parties hereto agree to
         cooperate and use their best efforts to defend against and re-
         spond thereto.  It is understood and agreed that after the Ef-
         fective Time, Bancorp shall indemnify and hold harmless, as and
         to the fullest extent permitted by law, each such Indemnified
         Party against any losses, claims, damages, liabilities, costs,
         expenses (including reasonable attorneys' fees and expenses in
         advance of the final disposition of any claim, suit, proceeding
         or investigation to each Indemnified Party to the fullest ex-
         tent permitted by law upon receipt of any undertaking required
         by applicable law), judgments, fines and amounts paid in
         settlement in connection with any such threatened or actual
         claim, action, suit, proceeding or investigation and in the
         event of any such threatened or actual claim, action, suit,
         proceeding, or investigation (whether asserted or arising be-
         fore or after the Effective Time), the Indemnified Parties may
         retain counsel reasonably satisfactory to them after consulta-
         tion with Bancorp; provided, however, that (1) Bancorp shall
         have the right to assume the defense thereof and upon such as-
         sumption Bancorp shall not be liable to any Indemnified Party
         for any legal expenses of other counsel or any other expenses
         subsequently incurred by any Indemnified Party in connection
         with the defense thereof, except that if Bancorp elects not to
         assume such defense or counsel for the Indemnified Parties rea-
         sonably advises the Indemnified Parties that there are issues
         which raise conflicts of interest between Bancorp and the In-
         demnified Parties, the Indemnified Parties may retain counsel
         reasonably satisfactory to them after consultation with Ban-
         corp, and Bancorp shall pay the reasonable fees and expenses of
         such counsel for the Indemnified Parties, (2) Bancorp shall be
         obligated pursuant to this paragraph to pay for only one firm
         of counsel for all Indemnified Parties, unless an Indemnified
         Party shall have reasonably concluded, based on the advice of
         counsel, that in order to be adequately represented, separate
         counsel is necessary for such Indemnified Party, in which case,
         Bancorp shall be obligated to pay for such separate counsel,
         (3) Bancorp shall not be liable for any settlement effected
         without its prior written consent (which consent shall not be
         unreasonably withheld) and (4) Bancorp shall have no obligation
         hereunder to any Indemnified Party when and if a court of com-
         petent jurisdiction shall ultimately determine, and such deter-
         mination shall have become final and nonappealable, that indem-
         nification of such Indemnified Party in the manner contemplated
         hereby is prohibited by applicable law.  Any Indemnified Party
         wishing to claim Indemnification under this Section 6.8, upon 



                                       -44-<PAGE>







         learning of any such claim, action, suit, proceeding or inves-
         tigation, shall notify Bancorp thereof, provided that the fail-
         ure to so notify shall not affect the obligations of Bancorp
         under this Section 6.8 except to the extent such failure to
         notify materially prejudices Bancorp.  Bancorp's obligations
         under this Section 6.8 continue in full force and effect for a
         period of six (6) years from the Effective Time; provided, how-
         ever, that all rights to indemnification in respect of any
         claim (a "Claim") asserted or made within such period shall
         continue until the final disposition of such Claim and provided
         further that Bancorp shall have the right of set-off against
         any payments required to be made by Bancorp to an Indemnified
         Party pursuant to this Section 6.8(a) to the extent that such
         Indemnified Party shall have received the indemnification to
         which such Indemnified Party is entitled from an insurer under
         a directors' and officers' liability insurance policy main-
         tained by CBI or Bancorp.  Notwithstanding the foregoing provi-
         sions of this Section 6.8(a), Bancorp shall have no obligation
         to indemnify the Indemnified Parties (or advance expenses to
         them) except to the extent they would be entitled to such in-
         demnification (or advance) under the provisions of Bancorp's
         Articles of Incorporation or Bylaws or any agreement to which
         Bancorp is a party as in effect on the date of this Agreement
         if such Indemnified Parties had been officers or directors of
         Bancorp at the time of the event giving rise to such indemnifi-
         cation.

                   (b)  Bancorp shall use its best efforts to cause the
         persons serving as officers and directors of CBI immediately
         prior to the Effective Time to be covered for a period of six
         (6) years from the Effective Time by the directors' and offic-
         ers' liability insurance policy maintained by Bancorp, if any
         (provided that Bancorp may substitute therefor policies of at
         least the same coverage and amounts containing terms and condi-
         tions that are not less advantageous than such policy) with
         respect to acts or omissions occurring prior to the Effective
         Time which were committed by such officers and directors in
         their capacity as such; provided, however, that in no event
         shall Bancorp be required to expend more than 200 percent of
         the current amount expended by CBI (the "Insurance Amount") to
         maintain or procure insurance coverage pursuant hereto and fur-
         ther provided that if Bancorp is unable to maintain or obtain
         the insurance called for by this Section 6.8(b), Bancorp shall
         use its best efforts to obtain as much comparable insurance as
         is available for the Insurance Amount.

                   (c)  In the event Bancorp or any of its successors or
         assigns (i) consolidates with or merges into any other person
         and shall not be the continuing or surviving corporation or
         entity of such consolidation or merger, or (ii) transfers or 



                                       -45-<PAGE>







         conveys all or substantially all of its properties and assets
         to any person, then, and in each such case, to the extent nec-
         essary, proper provision shall be made so that the successors
         and assigns of Bancorp assume the obligations set forth in this
         section.

                   (d)  The provisions of this Section 6.8 are intended
         to be for the benefit of, and shall be enforceable by, each
         Indemnified Party and his or her heirs and representatives.

                   6.9. Additional Agreements.  In case at any time af-
         ter the Effective Time any further action is necessary or de-
         sirable to carry out the purposes of this Agreement (including,
         without limitation, any merger between a Subsidiary of Bancorp
         and a Subsidiary of CBI) or to vest the Surviving Corporation
         with full title to all properties, assets, rights, approvals,
         immunities and franchises of any of the parties to the Merger,
         the proper officers and directors of each party to this Agree-
         ment and their respective Subsidiaries shall take all such nec-
         essary action as may be reasonably requested by, and at the
         sole expense of, Bancorp.  Pending the Effective Time, Bancorp
         and CBI shall consult with one another and cooperate as reason-
         ably requested by Bancorp to facilitate the integration of
         their respective operations as promptly as practicable after
         the Effective Time.  Such cooperation shall include, if re-
         quested, the entering into of merger agreements between or
         among their respective Subsidiaries and the filing of appropri-
         ate regulatory applications with respect thereto (conditioned
         upon the effectiveness of the Merger), communicating with em-
         ployees, consultation regarding material contracts, renewals,
         and capital commitments to be entered into by CBI and its Sub-
         sidiaries, coordination regarding third-party service agree-
         ments with a view to providing common products and services as
         expeditiously as practicable following the Effective Time, mak-
         ing arrangements for employee training prior to the Effective
         Time and taking action to facilitate an orderly conversion of
         data processing operations to occur promptly following the Ef-
         fective Time, provided that the cooperation required under this
         Section 6.9 shall not be deemed to require actions that would
         materially delay or impede the Merger.

                   6.10.  Advice of Changes.  Bancorp and CBI shall
         promptly advise the other party of any change or event having,
         or that would be reasonably likely to have, a Material Adverse
         Effect on it or which it believes would or would be reasonably
         likely to cause or constitute a material breach of any of its
         representations, warranties or covenants contained herein.

                   6.11.  Dividends.  After the date of this Agreement,
         each of Bancorp and CBI shall coordinate with the other the 



                                       -46-<PAGE>







         declaration of any dividends in respect of Bancorp Common Stock
         and CBI Common Stock and the record dates and payment dates
         relating thereto, it being the intention of the parties hereto
         that holders of Bancorp Common Stock or CBI Common Stock shall
         not receive two dividends, or fail to receive one dividend, for
         any single calendar quarter with respect to their shares of
         Bancorp Common Stock and/or CBI Common Stock and any shares of
         Bancorp Common Stock any such holder receives in exchange
         therefor in the Merger.


                                   ARTICLE VII
                               CONDITIONS PRECEDENT

                   7.1.  Conditions to Each Party's Obligation to Effect
         the Merger.  The respective obligation of each party to effect
         the Merger shall be subject to the satisfaction at or prior to
         the Effective Time of the following conditions:

                   (a)  Shareholder Approval.  This Agreement and the
              transactions contemplated hereby shall have been approved
              and adopted by the requisite affirmative vote of the hold-
              ers of CBI Common Stock entitled to vote thereon.

                   (b)  Nasdaq Listing.  The shares of Bancorp Common
              Stock that shall be issued to the shareholders of CBI upon
              consummation of the Merger shall have been authorized for
              listing on the Nasdaq Stock Market National Market System
              subject to official notice of issuance.

                   (c)  Other Approvals.  All regulatory approvals re-
              quired to consummate the transactions contemplated hereby
              shall have been obtained without the imposition of any
              conditions that are in Bancorp's reasonable judgment un-
              duly burdensome and shall remain in full force and effect
              and all statutory waiting periods in respect thereof shall
              have expired (all such approvals and the expiration of all
              such waiting periods being referred to herein as the "Req-
              uisite Regulatory Approvals"), and all other material con-
              sents or approvals of any third party required in connec-
              tion with the consummation of the Merger as set forth in
              the CBI Disclosure Schedule or Bancorp Disclosure Schedule
              shall have been obtained.  For purposes of this paragraph,
              a divestiture required as a condition to any regulatory
              approval shall not be unduly burdensome if such divesti-
              ture is consistent with Department of Justice and Federal
              Reserve Board guidelines, policies, and practices regard-
              ing the merger of bank holding companies that have been
              utilized in transactions that have recently been reviewed
              prior to the date of this Agreement.



                                       -47-<PAGE>







                   (d)  Form S-4.  The S-4 shall have become effective
              under the Securities Act and no stop order suspending the
              effectiveness of the S-4 shall have been issued and no
              proceedings for that purpose shall have been initiated or
              threatened by the SEC.

                   (e)  No Injunctions or Restraints; Illegality.  No
              order, injunction or decree issued by any court or agency
              of competent jurisdiction or other legal restraint or pro-
              hibition (an "Injunction") preventing the consummation of
              the Merger or any of the other transactions contemplated
              by this Agreement shall be in effect.  No statute, rule,
              regulation, order, injunction or decree shall have been
              enacted, entered, promulgated or enforced by any Govern-
              mental Entity which prohibits, restricts or makes illegal
              consummation of the Merger.

                   (f)  Federal Tax Opinions.  Bancorp shall have re-
              ceived an opinion of Miller, Nash, Wiener, Hager &
              Carlsen, counsel to Bancorp, and CBI shall have received
              an opinion of Wachtell, Lipton, Rosen & Katz, counsel to
              CBI, in form and substance reasonably satisfactory to Ban-
              corp and CBI, dated as of the Effective Time, substan-
              tially to the effect that, on the basis of facts, rep-
              resentations and assumptions set forth in such opinion
              which are consistent with the state of facts existing at
              the Effective Time, the Merger will be treated for Federal
              income tax purposes as part of one or more reorganizations
              within the meaning of Section 368 of the Code and that
              accordingly:

                        (a)  No gain or loss will be recognized by Ban-
                   corp or CBI as a result of the Merger;

                        (b)  No gain or loss will be recognized by the
                   shareholders of CBI who exchange their CBI Common
                   Stock solely for Bancorp Common Stock pursuant to the
                   Merger (except with respect to cash received in lieu
                   of a fractional share interest in Bancorp Common
                   Stock); and

                        (c)  The tax basis of the Bancorp Common Stock
                   received by shareholders who exchange all of their
                   CBI Common Stock solely for Bancorp Common Stock in
                   the Merger will be the same as the tax basis of the
                   CBI Common Stock surrendered in exchange therefor
                   (reduced by any amount allocable to a fractional
                   share interest for which cash is received).





                                       -48-<PAGE>







                        In rendering such opinion, counsel may require
                   and rely upon representations contained in certifi-
                   cates of officers of Bancorp, CBI and others.

                   (g)  Pooling of Interests.  Bancorp and CBI shall
              each have received letters from Deloitte & Touche LLP and
              KPMG Peat Marwick LLP, respectively, addressed to Bancorp
              and CBI, respectively, to the effect that the Merger will
              qualify for "pooling of interests" accounting treatment.

                   7.2. Conditions to Obligations of Bancorp.  The obli-
         gation of Bancorp to effect the Merger is also subject to the
         satisfaction or waiver by Bancorp at or prior to the Effective
         Time of the following conditions:

                   (a)  Representations and Warranties.  The representa-
              tions and warranties of CBI set forth in this Agreement
              shall be true and correct in all material respects as of
              the date of this Agreement and (except to the extent such
              representations and warranties speak as of an earlier
              date) as of the Closing Date as though made on and as of
              the Closing Date.  Bancorp shall have received a certifi-
              cate signed on behalf of CBI by the Chief Executive Of-
              ficer and the Chief Financial Officer of CBI to the fore-
              going effect.

                   (b)  Performance of Obligations of CBI.  CBI shall
              have performed in all material respects all obligations
              required to be performed by it under this Agreement at or
              prior to the Closing Date, and Bancorp shall have received
              a certificate signed on behalf of CBI by the Chief Execu-
              tive Officer and the Chief Financial Officer of CBI to
              such effect.

                   (c)  CBI Rights Agreement.  The rights issued pursu-

              ing effect.

                   (b)  Performance of Obligations of Bancorp.  Bancorp

                            TERMINATION AND AMENDMENT

                   8.1. Termination.  This Agreement may be terminated
         at any time prior to the Effective Time, whether before or af-
         ter approval of the matters presented in connection with the
         Merger by the shareholders of CBI:

                   (a)  by mutual consent of Bancorp and CBI in a writ-
              ten instrument, if the Board of Directors of each so de-
              termines by a vote of a majority of the members of its
              entire Board;

                   (b)  by either the Board of Directors of Bancorp or
              the Board of Directors of CBI (i) if any Governmental En-
              tity which must grant a Requisite Regulatory Approval has
              denied approval of the Merger and such denial has become
              final and nonappealable or (ii) any Governmental Entity of
              competent jurisdiction shall have issued a final nonap-
              pealable order enjoining or otherwise prohibiting the con-
              summation of the transactions contemplated by this Agree-
              ment;

                   (c)  by either the Board of Directors of Bancorp or
              the Board of Directors of CBI if the Merger shall not have
              been consummated on or before January 31, 1997, unless the
              failure of the Closing to occur by such date shall be due
              to the breach by the party seeking to terminate this
              Agreement of any representation, warranty, covenant, or
              other agreement of such party set forth herein;

                   (d)  by either the Board of Directors of Bancorp or
              the Board of Directors of CBI (provided that the termi-
              nating party is not then in material breach of any repre-
              sentation, warranty, covenant or other agreement contained
              herein) if there shall have been a material breach of any 



                                       -50-<PAGE>







              of the covenants or agreements or any of the representa-
              tions or warranties set forth in this Agreement on the
              part of the other party, which breach is not cured within
              forty-five (45) days following written notice to the party
              committing such breach, or which breach, by its nature,
              cannot be cured prior to the Closing; or

                   (e)  by either Bancorp or CBI if any approval of the
              shareholders of CBI required for the consummation of the
              Merger shall not have been obtained by reason of the fail-
              ure to obtain the required vote at a duly held meeting of
              shareholders or at any adjournment or postponement
              thereof.

                   8.2.  Effect of Termination.  In the event of termi-
         nation of this Agreement by either Bancorp or CBI as provided
         in Section 8.1, this Agreement shall forthwith become void and
         have no effect, and none of Bancorp, CBI, any of their respec-
         tive Subsidiaries or any of the officers or directors of any of
         them shall have any liability of any nature whatsoever hereun-
         der, or in connection with the transactions contemplated
         hereby, except (i) Sections 6.2(b), 8.2, 9.2 and 9.3, shall
         survive any termination of this Agreement, and (ii) notwith-
         standing anything to the contrary contained in this Agreement,
         neither Bancorp nor CBI shall be relieved or released from any
         liabilities or damages arising out of its intentional or will-
         ful breach of any provision of this Agreement.

                   8.3. Amendment.  Subject to compliance with applica-
         ble law, this Agreement may be amended by the parties hereto,
         by action taken or authorized by their respective Boards of
         Directors, at any time before or after approval of the matters
         presented in connection with the Merger by the shareholders of
         CBI; provided, however, that after any approval of the transac-
         tions contemplated by this Agreement by CBI's shareholders,
         there may not be, without further approval of such sharehold-
         ers, any amendment of this Agreement that reduces the amount or
         changes the form of the consideration to be delivered to the
         CBI shareholders hereunder other than as contemplated by this
         Agreement.  This Agreement may not be amended except by an in-
         strument in writing signed on behalf of each of the parties
         hereto.

                   8.4.  Extension; Waiver.  At any time prior to the
         Effective Time, the parties hereto, by action taken or autho-
         rized by their respective Board of Directors, may, to the ex-
         tent legally allowed, (a) extend the time for the performance
         of any of the obligations or other acts of the other parties
         hereto, (b) waive any inaccuracies in the representations and 




                                       -51-<PAGE>







         warranties contained herein or in any document delivered pursu-
         ant hereto, and (c) waive compliance with any of the agreements
         or conditions contained herein; provided, however, that after
         any approval of the transactions contemplated by this Agreement
         by CBI's shareholders, there may not be, without further ap-
         proval of such shareholders, any extension or waiver of this
         Agreement or any portion thereof which reduces the amount or
         changes the form of the consideration to be delivered to the
         CBI shareholders hereunder other than as contemplated by this
         Agreement.  Any agreement on the part of a party hereto to any
         such extension or waiver shall be valid only if set forth in a
         written instrument signed on behalf of such party, but such
         extension or waiver or failure to insist on strict compliance
         with an obligation, covenant, agreement or condition shall not
         operate as a waiver of, or estoppel with respect to, any subse-
         quent or other failure.


                                    ARTICLE IX

         business days after the satisfaction or waiver (subject to ap-
         plicable law) of the latest to occur of the conditions set
         forth in Article VII hereof (the "Closing Date").

                   9.2. Nonsurvival of Representations, Warranties, and

         delivered pursuant to this Agreement (other than pursuant to
         the CBI Option Agreement, which shall terminate in accordance
         with its terms), including any rights arising out of any breach
         of such representations, warranties, covenants, and agreements,
         shall survive the Effective Time, except for those covenants
         and agreements contained herein and therein that by their terms
         apply in whole or in part after the Effective Time.

                                       -53-<PAGE>







         and headings contained in this Agreement are for reference pur-
         poses only and shall not affect in any way the meaning or in-
         terpretation of this Agreement.  Whenever the words "include,"
         "includes," and "including" are used in this Agreement, they
         shall be deemed to be followed by the words "without limita-
         tion."  No provision of this Agreement shall be construed to
         require CBI, Bancorp, or any of their respective Subsidiaries
         or affiliates to take any action that would violate any ap-
         plicable law, rule, or regulation.  Any exception to the repre-
         sentations and warranties of CBI or Bancorp, respectively, con-
         tained in the CBI Disclosure Schedule or Bancorp Disclosure
         Schedule, as the case may be, shall be effective only as to the
         particular sections of this Agreement specifically referenced
         in such exception.

                   9.6.  Counterparts.  This Agreement may be executed
         in counterparts, all of which shall be considered one and the
         same agreement and shall become effective when counterparts
         have been signed by each of the parties and delivered to the
         other parties, it being understood that all parties need not
         sign the same counterpart.

                   9.7.  Entire Agreement.  This Agreement (including
         the documents and the instruments referred to herein) consti-
         tutes the entire agreement and supersedes all prior agreements
         and understandings, both written and oral, among the parties
         with respect to the subject matter hereof other than the CBI
         Option Agreement and the Confidentiality Agreements.

                   9.8.  Governing Law.  This Agreement shall be gov-
         erned and construed in accordance with the laws of the State of
         Oregon, without regard to any applicable conflicts of law rules
         thereof.

                   9.9  Severability.  Any term or provision of this
         Agreement that is invalid or unenforceable in any jurisdiction
         shall, as to that jurisdiction, be ineffective to the extent of
         such invalidity or unenforceability without rendering invalid
         or unenforceable the remaining terms and provisions of this
         Agreement or affecting the validity or enforceability of any of
         the terms or provisions of this Agreement in any other juris-
         diction.  If any provision of this Agreement is so broad as to
         be unenforceable, the provision shall be interpreted to be only
         so broad as is enforceable.

                   9.10.  Publicity.  Except as otherwise required by
         applicable law or the rules of the Nasdaq Stock Market, neither
         Bancorp nor CBI shall, or shall permit any of its Subsidiaries
         to, issue or cause the publication of any press release or
         other public announcement with respect to, or otherwise make 



                                       -54-<PAGE>







         any public statement concerning, the transactions contemplated
         by this Agreement without the consent of the other party, which
         consent shall not be unreasonably withheld.

                   9.11.  Assignment.  Neither this Agreement nor any of
         the rights, interests, or obligations shall be assigned by any
         of the parties hereto (whether by operation of law or other-
         wise) without the prior written consent of the other parties.
         Subject to the preceding sentence, this Agreement will be bind-
         ing upon, inure to the benefit of, and be enforceable by the
         parties and their respective successors and assigns.  Except as
         otherwise specifically provided in Section 6.7(b) and Section
         6.8 hereof, this Agreement (including the documents and instru-
         ments referred to herein) is not intended to confer upon any
         person other than the parties hereto any rights or remedies
         hereunder.

                   IN WITNESS WHEREOF, each of the parties has caused
         this Agreement to be executed by its respective officers there-
         unto duly authorized as of the date first above written.

                              STOCK OPTION AGREEMENT

                   THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                    CERTAIN PROVISIONS CONTAINED HEREIN AND TO
                          RESALE RESTRICTIONS UNDER THE
                        SECURITIES ACT OF 1933, AS AMENDED


                   STOCK OPTION AGREEMENT, dated February 12, 1996, be-
         tween CALIFORNIA BANCSHARES, INC., a Delaware corporation ("Is-
         suer"), and U.S. BANCORP, an Oregon corporation ("Grantee").


                               W I T N E S S E T H:

                   WHEREAS, Grantee and Issuer have entered into an
         Agreement and Plan of Merger dated February 11, 1996 (the
         "Merger Agreement"); and

                   WHEREAS, as a condition to Grantee's entering into
         the Merger Agreement and in consideration therefor, Issuer has
         agreed to grant Grantee the Option (as hereinafter defined):

                   NOW, THEREFORE, in consideration of the foregoing and
         the mutual covenants and agreements set forth herein and in the
         Merger Agreement, the parties hereto agree as follows:

                   1.   (a)  Issuer hereby grants to Grantee an uncondi-
         tional, irrevocable option (the "Option") to purchase, subject
         to the terms hereof, up to 2,002,076 fully paid and nonassess-
         able shares of Issuer's Common Stock, $2.50 par value per share
         ("Common Stock"), at a price of $25.75 per share (the "Option
         Price"); provided further that in no event shall the number of
         shares of Common Stock for which this Option is exercisable
         exceed 19.9 percent of the Issuer's issued and outstanding
         shares of Common Stock.  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 herein set forth.

                   (b)  In the event that any additional shares of Com-
         mon Stock are issued or otherwise become outstanding after the
         date of this Agreement (other than pursuant to this Agreement),
         the number of shares of Common Stock subject to the Option
         shall be increased so that, after such issuance, it equals 19.9
         percent of the number of shares of Common Stock then issued and
         outstanding without giving effect to any shares subject or is-
         sued pursuant to the Option.  Nothing contained in this Section
         1(b) or elsewhere in this Agreement shall be deemed to autho-
         rize Issuer or Grantee to breach any provision of the Merger
         Agreement.<PAGE>







                   2.   (a)  The Holder (as hereinafter defined) may
         exercise the Option, in whole or in part, and from time to
         time, if, but only if, both an Initial Triggering Event (as
         hereinafter defined) and a Subsequent Triggering Event (as
         hereinafter defined) shall have occurred prior to the occur-
         rence of an Exercise Termination Event (as hereinafter de-
         fined), provided that the Holder shall have sent the written
         notice of such exercise (as provided in subsection (e) of this
         Section 2) within 90 days following such Subsequent Triggering
         Event.  Each of the following shall be an Exercise Termination
         Event:  (i) the Effective Time of the Merger; (ii) termination
         of the Merger Agreement in accordance with the provisions
         thereof if such termination occurs prior to the occurrence of

                   received Grantee's prior written consent,
                   shall have entered into an agreement to engage

                   this Agreement, "Acquisition Transaction"
                   shall mean (w) a merger or consolidation, or
                   any similar transaction, involving Issuer or

                   term "beneficial ownership" for purposes of
                   this Option Agreement having the meaning as-
                   signed thereto in Section 13(d) of the 1934
                   Act, and the rules and regulations thereun-
                   der);

                       (iv)  Any person other than Grantee or any
                   Grantee Subsidiary shall have made a bona fide
                   proposal to Issuer or its stockholders by pub-
                   lic announcement or written communication that

                   to engage in an Acquisition Transaction;

                        (v)  After an overture is made by a third
                   party to Issuer or its stockholders to engage
                   in an Acquisition Transaction, Issuer shall
                   have breached any covenant or obligation con-
                   tained in the Merger Agreement and such breach
                   (x) would entitle Grantee to terminate the
                   Merger Agreement and (y) shall not have been
                   cured prior to the Notice Date (as defined

                   its prior written consent, shall have filed an
                   application or notice with the Federal Reserve
                   Board, or other federal or state bank regula-
                   tory authority, which application or notice
                   has been accepted for processing, for approval
                   to engage in an Acquisition Transaction.

                   (c)  The term "Subsequent Triggering Event" shall
         mean either of the following events or transactions occurring
         after the date hereof:






                                      - 4 -<PAGE>







                        (i)  The acquisition by any person of
                   beneficial ownership of 25 percent or more of
                   the then outstanding Common Stock; or 

                       (ii)  The occurrence of the Initial Trig-
                   gering Event described in clause (i) of sub-
                   section (b) of this Section 2, except that the
                   percentage referred to in clause (y) shall be
                   25 percent.

                   (d)  Issuer shall notify Grantee promptly in writing
         of the occurrence of any Initial Triggering Event or Subsequent
         Triggering Event (together, a "Triggering Event"), it being
         understood that the giving of such notice by Issuer shall not
         be a condition to the right of the Holder to exercise the Op-
         tion.

                   (e)  In the event the Holder is entitled to and
         wishes to exercise the Option, it shall send to Issuer a writ-
         ten notice (the date of which being herein referred to as the
         "Notice Date") specifying (i) the total number of shares it
         will purchase pursuant to such exercise and (ii) a place and date
         not earlier than three business days nor later than 60 business
         days from the Notice Date for the closing of such purchase (the
         "Closing Date"); provided that if prior notification to or ap-
         proval of the 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 ap-
         proval 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 notifica-
         tion 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.

                   (f)  At the closing referred to in subsection (e) of
         this Section 2, the Holder shall pay to Issuer the aggregate
         purchase price for the shares of Common Stock purchased pursu-
         ant to the exercise of the Option in immediately available
         funds by wire transfer to a bank account designated by Issuer,
         provided that failure or refusal of Issuer to designate such a
         bank account shall not preclude the Holder from exercising the
         Option.

                   (g)  At such closing, simultaneously with the deliv-
         ery of immediately available funds as provided in subsection
         (f) of this Section 2, Issuer 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 



                                      - 5 - <PAGE>







         should be exercised in part only, a new Option evidencing the
         rights of the Holder thereof to purchase the balance of the
         shares purchasable hereunder, and the Holder shall deliver to
         Issuer 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.

                   (h)  Certificates for Common Stock delivered at a
         closing hereunder 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 Issuer and
                   to resale restrictions arising under the
                   Securities Act of 1933, as amended.  A
                   copy of such agreement is on file at the
                   principal office of Issuer and will be
                   provided to the holder hereof without
                   charge upon receipt by Issuer of a writ-
                   ten request therefor."

         It is understood and agreed that:  (i) the reference to the
         resale restrictions of the Securities Act of 1933, as amended
         (the "1933 Act"), in the above legend shall be removed by de-
         livery of substitute certificate(s) without such reference if
         the Holder shall have delivered to Issuer a copy of a letter
         from the staff of the SEC, or an opinion of counsel, in form
         and substance reasonably satisfactory to Issuer, to the effect
         that such legend is not required for purposes of the 1933 Act;
         (ii) the reference to the provisions to this Agreement in the
         above legend shall be removed by delivery of substitute certi-
         ficate(s) without such reference if the shares have been sold
         or transferred in compliance with the provisions of this Agree-
         ment and under circumstances that do not require the retention
         of such reference; and (iii) the legend shall be removed in its
         entirety if the conditions in the preceding clauses (i) and
         (ii) are both satisfied.  In addition, such certificates shall
         bear any other legend as may be required by law.

                   (i)  Upon the giving by Holder to Issuer of the writ-
         ten notice of exercise of the Option provided for under subsec-
         tion (e) of this Section 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 Issuer shall then be closed or that
         certificates representing such shares of Common Stock shall not 



                                      - 6 -<PAGE>







         then be actually delivered to the Holder.  Issuer shall pay all
         expenses, and any and all United States federal, state, and
         local taxes and other charges that may be payable in connection
         with the preparation, issue, and delivery of stock certificates
         under this Section 2 in the name of the Holder or its assignee,
         transferee, or designee.

                   3.   Issuer agrees:  (i) that 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, war-
         rants, convertible securities, and other rights to purchase
         Common Stock; (ii) that it will not, by charter amendment or
         through reorganization, consolidation, merger, dissolution, or
         sale of assets, or by any other voluntary act, avoid or seek to
         avoid the observance or performance of any of the covenants,
         stipulations, or conditions to be observed or performed here-
         under by Issuer; (iii) promptly to take all action as may from
         time to time be required (including (x) complying with all pre-
         merger notification, reporting, and waiting period requirements
         specified in 15 USC Section 18 and regulations promulgated
         thereunder and (y) in the event, under the Bank Holding Company
         Act of 1956, as amended (the "BHCA"), 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 prepar-
         ing 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 Issuer duly and effectively to issue shares of
         Common Stock pursuant hereto, and (iv) promptly to take all
         action provided herein to protect the rights of the Holder
         against dilution.

                   4.   This Agreement (and the Option granted hereby)
         are exchangeable, without expense, at the option of the Holder,
         upon presentation and surrender of this Agreement at the prin-
         cipal office of Issuer, for other Agreements providing for Op-
         tions of different denominations entitling the holder thereof
         to purchase, on the same terms and subject to the same condi-
         tion as are set forth herein, in the aggregate the same number
         of shares of Common Stock purchasable hereunder.  The terms
         "Agreement" and "Option" as used herein include any Stock Op-
         tion Agreements and related Options for which this Agreement
         (and the Option granted hereby) may be exchanged.  Upon receipt
         by Issuer of evidence reasonably satisfactory to it of the
         loss, theft, destruction, or mutilation of this Agreement, and 




                                      - 7 -<PAGE>







         (in the case of loss, theft, or destruction) of reasonably sat-
         isfactory indemnification, and upon surrender and cancellation
         of this Agreement, if mutilated, Issuer will execute and de-
         liver a new Agreement of like tenor and date.  Any such new
         Agreement executed and delivered shall constitute an additional
         contractual obligation on the part of Issuer, whether or not
         the Agreement so lost, stolen, destroyed, or mutilated shall at
         any time be enforceable by anyone.

                   5.   In addition to the adjustment in the number of
         shares of Common Stock that are purchasable upon exercise of
         the Option pursuant to Section 1 of this Agreement, 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 provided in this Section 5.  In the event of
         any change in, or distributions in respect of, the Common Stock
         by reason of stock dividends, split-ups, mergers, recapitaliza-
         tions, combinations, subdivisions, conversions, exchanges of
         shares, distributions on or in respect of the Common Stock that
         would be prohibited under be terms of the Merger Agreement, or
         the like, the type and number of shares of Common Stock pur-
         chasable upon exercise hereof and the Option Price shall be
         appropriately adjusted in such manner as shall fully preserve
         the economic benefits provided hereunder and proper provision
         shall be made in any agreement governing any such transaction
         to provide for such proper adjustment and the full satisfaction
         of the Issuer's obligations hereunder.

                   6.   Upon the occurrence of a Subsequent Triggering
         Event that occurs prior to an Exercise Termination Event, Is-
         suer shall, at the request of Grantee delivered within 90 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
         hereto), promptly prepare, file, and keep current a shelf reg-
         istration statement under the 1933 Act covering this Option and
         any shares issued and issuable pursuant to this Option and
         shall use its reasonable best efforts to cause such registra-
         tion statement to become effective and remain current in order
         to permit the sale or other disposition of this Option and 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 Grantee.  Issuer will use its reason-
         able 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 the date such registration
         statement first becomes effective or such shorter time as may
         be reasonably necessary to effect such sales or other disposi-
         tions.  Grantee shall have the right to demand two such regis-
         trations.  The foregoing notwithstanding, if, at the time of 



                                      - 8 -<PAGE>







         any request by Grantee for registration of the Option or Option
         Shares as provided above, Issuer is in registration with re-
         spect to an underwritten public offering of shares of Common
         Stock, and if in the good faith judgment of the managing under-
         writer or managing underwriters, or, if none, the sole under-
         writer or underwriters, of such offering the inclusion of the
         Holder's Option or Option Shares would interfere with the suc-
         cessful marketing of the shares of Common Stock offered by Is-
         suer, the number of Option Shares otherwise to be covered in
         the registration statement contemplated hereby may be reduced;
         and 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 percent
         of the total number of shares to be sold by the Holder and Is-
         suer in the aggregate; and provided further, however, that if
         such reduction occurs, then the Issuer shall file a registra-
         tion statement for the balance as promptly as practical and no
         reduction shall thereafter occur.  Each such Holder shall pro-
         vide all information reasonably requested by Issuer for inclu-
         sion in any registration statement to be filed hereunder.  If
         requested by any such Holder in connection with such registra-
         tion, Issuer 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 Issuer.  Upon receiving any
         request under this Section 6 from any Holder, Issuer agrees to
         send a copy thereof to any other person known to Issuer to be
         entitled to registration rights under this Section 6, in each
         case by promptly mailing the same, postage prepaid, to the ad-
         dress of record of the persons entitled to receive such copies.
         Notwithstanding anything to the contrary contained herein, in
         no event shall Issuer be obligated to effect more than two reg-
         istrations pursuant to this Section 6 by reason of the fact
         that there shall be more than one Grantee as a result of any
         assignment or division of this Agreement.

                   7.   (a)  Immediately prior to the occurrence of a
         Repurchase Event (as defined below), (i) following a request of
         the Holder, delivered prior to an Exercise Termination Event,
         Issuer (or any successor thereto) shall repurchase the Option
         from the Holder at a price (the "Option Repurchase Price")
         equal to the amount by which (A) the market/offer price (as
         defined below) exceeds (B) the Option Price, multiplied by the
         number of shares for which this Option may then be exercised
         and (ii) at the request of the owner of Option Shares from time
         to time (the "Owner"), delivered within 90 days of such occur-
         rence (or such later period as provided in Section 10), Issuer
         shall repurchase such number of the Option Shares from the
         Owner as the Owner shall designate at a price (the "Option 



                                      - 9 -<PAGE>







         Share Repurchase Price") equal to the market/offer price multi-
         plied by the number of Option Shares so designated.  The term
         "market/offer price" shall mean the highest of the following
         amounts with respect to the six-month period immediately pre-
         ceding the date the Holder gives notice of the required repur-
         chase of this Option or the Owner gives notice of the required
         repurchase of Option Shares, as the case may be: (i) the price
         per share of Common Stock at which a tender offer or exchange
         offer therefor has been made, (ii) the price per share of Com-
         mon Stock to be paid by any third party pursuant to an agree-
         ment with Issuer, (iii) the highest closing price for shares of
         Common Stock, or (iv) in the event of a sale of all or a sub-
         stantial portion of Issuer's assets, the sum of the price paid
         in such sale for such assets and the current market value of
         the remaining assets of Issuer as determined by a nationally
         recognized investment banking firm selected by the Holder or
         the Owner, as the case may be, divided by the number of shares
         of Common Stock of Issuer outstanding at the time of such sale.
         In determining the market/offer price, the value of consider-
         ation other than cash shall be determined by a nationally rec-
         ognized investment banking firm selected by the Holder or
         Owner, as the case may be, and reasonably acceptable, to Is-
         suer.  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 Grantee relating to Grantee's rights un-
         der this Option or with respect to the Option Shares or di-
         rectly or indirectly relating to Issuer, Grantee shall, not-
         withstanding the terms of such agreement or understanding, at
         any time upon the occurrence of a Subsequent Triggering Event
         of the type set forth in Section 3(d)(i) without Issuer's ap-
         proval, recommendation or consent, promptly request that Issuer
         repurchase the Option and any Option Shares held by Grantee as
         provided in this Section 8 and Issuer shall do so.

                   (b)  The Holder and the Owner, as the case may be,
         may exercise its right to require Issuer to repurchase the Op-
         tion and any Option Shares pursuant to this Section 7 by sur-
         rendering for such purpose to Issuer, 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 Issuer to repurchase this Option and/or the Option
         Shares in accordance with the provisions of this Section 7.
         Within the latter to occur of (x) 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 and (y) the time that is immediately prior to the oc-
         currence of a Repurchase Event, Issuer shall deliver or cause
         to be delivered to Holder the Option Repurchase Price, and/or 



                                      - 10 -<PAGE>







         to the Owner the Option Share Repurchase Price therefor or the
         portion thereof that Issuer is not then prohibited under ap-
         plicable law and regulation from so delivering.

                   (c)  To the extent that Issuer is prohibited under
         applicable law or regulation from repurchasing the Option and/
         or the Option Shares in full, Issuer shall immediately so no-
         tify 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 busi-
         ness days after the date on which Issuer is no longer so pro-
         hibited; provided, however, that if Issuer at any time after
         delivery of a notice of repurchase pursuant to paragraph (b) of
         this Section 7 is prohibited under applicable law or regulation
         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 Issuer hereby undertakes to
         use its best efforts to obtain all required regulatory and le-
         gal approvals and file any required notices as promptly as
         practicable in order to accomplish such repurchase), the Holder
         or Owner may revoke its notice of repurchase of the Option or
         the Option Shares either in whole or to the extent of the pro-
         hibition, whereupon, in the latter case, Issuer shall promptly
         (i) deliver to the Holder and/or the Owner, as appropriate,
         that portion of the Option Repurchase Price or the Option Share
         Repurchase Price that Issuer is not prohibited from delivering;
         and (ii) deliver, as appropriate, either (A) to the Holder, a
         new Stock Option Agreement evidencing the right of the Holder
         to purchase that number of shares of Common 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 nu-
         merator of which is the Option Repurchase Price less the por-
         tion thereof theretofore delivered to the Holder and the de-
         nominator of which is the Option Repurchase Price, or (B) to
         the Owner, a certificate for the Option Shares it is then so
         prohibited from repurchasing.

                   (d)  For purposes of this Section 7, a Repurchase
         Event shall be deemed to have occurred (i) upon the consumma-
         tion of any merger, consolidation, or similar transaction in-
         volving Issuer or any purchase, lease, or other acquisition of
         all or a substantial portion of the assets of Issuer, other
         than any such transaction which would not constitute an Acqui-
         sition Transaction pursuant to the proviso to Section 2(b)(i)
         hereof or (ii) upon the acquisition by any person of beneficial
         ownership of 50 percent or more of the then outstanding shares
         of Common Stock, provided that no such event shall constitute a 



                                      - 11 -<PAGE>







         Repurchase Event unless a Subsequent Triggering Event shall
         have occurred prior to an Exercise Termination Event.  The par-
         ties hereto agree that Issuer's obligations to repurchase the
         Option or Option Shares under this Section 7 shall not termi-
         nate upon the occurrence of an Exercise Termination Event un-
         less no Subsequent Triggering Event shall have occurred prior
         to the occurrence of an Exercise Termination Event.

                   8.   (a)  In the event that prior to an Exercise Ter-
         mination Event, Issuer shall enter into an agreement (i) to
         consolidate with or merge into any person, other than Grantee
         or one of its Subsidiaries, and shall not be the continuing or
         surviving corporation of such consolidation or merger, (ii) to
         permit any person, other than Grantee or one of its Subsidiar-
         ies, to merge into Issuer and Issuer 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
         percent of the outstanding voting shares and voting share
         equivalents of the merged company, or (iii) to sell or other-
         wise transfer all or substantially all of its assets to any
         person, other than Grantee or one of its Subsidiaries, then,
         and in each such case, the agreement governing such transaction
         shall make proper provision so that the Option shall, upon the
         consummation of any such transaction and upon the terms and
         conditions set forth herein, be converted into, or exchanged
         for, an option (the "Substitute Option"), at the election of
         the Holder, of either (x) the Acquiring Corporation (as herein-
         after defined) or (y) any person that controls the Acquiring
         Corporation.

                   (b)  The following terms have the meanings indicated:

                   (1)  "Acquiring Corporation" shall mean (i)
              the continuing or surviving corporation of a con-
              solidation or merger with Issuer (if other than
              Issuer), (ii) Issuer in a merger in which Issuer is
              the continuing or surviving person, and (iii) the
              transferee of all or substantially all of Issuer's
              assets.

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

                   (3)  "Assigned Value" shall mean the market/
              offer price, as defined in Section 7.




                                  - 12 -<PAGE>







                   (4)  "Average Price" shall mean 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 date pre-
              ceding such consolidation, merger or sale; provided
              that if Issuer is the issuer of the Substitute Op-
              tion, the Average Price shall be computed with re-
              spect to a share of common stock issued by the per-
              son merging into Issuer or by any company which
              controls or is controlled by such person, as the
              Holder may elect.

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

                   (d)  The Substitute Option shall be exercisable for
         such number of shares of Substitute Common Stock as 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.

                   (e)  In no event, pursuant to any of the foregoing
         paragraphs, shall be Substitute Option be exercisable for more
         than 19.9 percent of the shares of Substitute Common Stock out-
         standing prior to the exercise of the Substitute Option.  In
         the event that the Substitute Option would be exercisable for
         more than 19.9 percent of the shares of Substitute Common Stock
         outstanding prior to exercise but for this clause (c), the is-
         suer of the Substitute Option (the "Substitute Option Issuer")
         shall make a cash payment to Holder equal to the excess of (i)
         the value of the Substitute Option without giving effect to the
         limitation in this clause (e) over (ii) the value of the Sub-
         stitute Option after giving effect to the limitation in this
         clause (e).  This difference in value shall be determined by a
         nationally recognized investment banking firm selected by the 



                                      - 13 -<PAGE>







         Holder or the Owner, as the case may be, and reasonably accept-
         able to the Acquiring Corporation.

                   (f)  Issuer shall not enter into any transaction de-
         scribed in subsection (a) of this Section 8 unless the Acquir-
         ing Corporation and any person that controls the Acquiring Cor-
         poration assume in writing all the obligations of Issuer here-
         under.

                   9.   (a)  At the request of the holder of the Substi-
         tute Option (the "Substitute Option Holder"), the issuer of the
         Substitute Option (the "Substitute Option Issuer") shall repur-
         chase the Substitute Option from the Substitute Option Holder
         at a price (the "Substitute Option Repurchase Price") equal to
         the amount by which (i) the Highest Closing Price (as hereinaf-
         ter defined) exceeds (ii) the exercise price of the Substitute
         Option, multiplied by the number of shares of Substitute Common
         Stock for which the Substitute Option may then be exercised,
         and at the request of the owner (the "Substitute Share Owner")
         of shares of Substitute Common Stock (the "Substitute Shares"),
         the Substitute Option Issuer shall repurchase the Substitute
         Shares at a price (the "Substitute Share Repurchase Price")
         equal to the Highest Closing Price multiplied by the number of
         Substitute Shares so designated.  The term "Highest Closing
         Price" shall mean the highest closing price for shares of Sub-
         stitute Common Stock within the six-month period immediately
         preceding the date the Substitute Option Holder gives notice of
         the required repurchase of the Substitute Option or the Substi-
         tute Share Owner gives notice of the required repurchase of the
         Substitute Shares, as applicable.

                   (b)  The Substitute Option Holder and the Substitute
         Share Owner, as the case may be, may exercise its respective
         rights to require the Substitute Option Issuer to repurchase
         the Substitute Option and the Substitute Shares pursuant to
         this Section 9 by surrendering for such purpose to the Substi-
         tute Option Issuer, at its principal office, the agreement for
         such Substitute Option (or, in the absence of such an agree-
         ment, a copy of this Agreement) and certificates for Substitute
         Shares accompanied by a written notice or notices stating that
         the Substitute Option Holder or the Substitute Share Owner, as
         the case may be, elects to require the Substitute Option Issuer
         to repurchase the Substitute Option and/or the Substitute
         Shares in accordance with the provisions of this Section 9.  As
         promptly as practicable, and in any event within five business
         days after the surrender of the Substitute Option and/or cer-
         tificates representing Substitute Shares and the receipt of
         such notice or notices relating thereto, the Substitute Option
         Issuer shall deliver or cause to be delivered to the Substitute
         Option Holder the Substitute Option Repurchase Price and/or to 



                                      - 14 -<PAGE>







         the Substitute Share Owner the Substitute Share Repurchase
         Price therefor or the portion thereof which the Substitute Op-
         tion Issuer is not then prohibited under applicable law and
         regulation from so delivering.

                   (c)  To the extent that the Substitute Option Issuer
         is prohibited under applicable law or regulation from repur-
         chasing the Substitute Option and/or the Substitute Shares in
         part or in full, the Substitute Option Issuer shall immediately
         so notify the Substitute Option Holder and/or the Substitute
         Share Owner and thereafter deliver or cause to be delivered,
         from time to time, to the Substitute Option Holder and/or the
         Substitute Share Owner, as appropriate, the portion of the Sub-
         stitute Share Repurchase Price, respectively, which it is no
         longer prohibited from delivering, within five business days
         after the date on which the Substitute Option Issuer is no
         longer so prohibited; provided, however, that if the Substitute
         Option Issuer is at any time after delivery of a notice of re-
         purchase pursuant to subsection (b) of this Section 9 prohib-
         ited under applicable law or regulation from delivering to the
         Substitute Option Holder and/or the Substitute Share Owner, as
         appropriate, the Substitute Option Repurchase Price and the
         Substitute Share Repurchase Price, respectively, in full (and
         the Substitute Option Issuer shall use its best efforts to re-
         ceive all required regulatory and legal approvals as promptly
         as practicable in order to accomplish such repurchase), the
         Substitute Option Holder or Substitute Share Owner may revoke
         its notice of repurchase of the Substitute Option or the Sub-
         stitute Shares either in whole or to the extent of the prohibi-
         tion, whereupon, in the latter case, the Substitute Option Is-
         suer shall promptly (i) deliver to the Substitute Option Holder
         or Substitute Share Owner, as appropriate, that portion of the
         Substitute Option Repurchase Price or the Substitute Share Re-
         purchase Price that the Substitute Option Issuer is not prohib-
         ited from delivering; and (ii) deliver, as appropriate, either
         (A) to the Substitute Option Holder, a new Substitute Option
         evidencing the right of the Substitute Option Holder to pur-
         chase that number of shares of the Substitute Common Stock ob-
         tained by multiplying the number of shares of the Substitute
         Common Stock for which the surrendered Substitute Option was
         exercisable at the time of delivery of the notice of repurchase
         by a fraction, the numerator of which is the Substitute Option
         Repurchase Price less the portion thereof theretofore delivered
         to the Substitute Option Holder and the denominator of which is
         the Substitute Option Repurchase Price, or (B) to the Substi-
         tute Share Owner, a certificate for the Substitute Option
         Shares it is then so prohibited from repurchasing.

                   10.  The 90-day period for exercise of certain rights
         under Sections 2, 6, 7, and 13 shall be extended:  (i) to the

         extent necessary to obtain all regulatory approvals for the
         exercise of such rights and for the expiration of all statutory
         waiting periods; and (ii) to the extent necessary to avoid li-
         ability under Section 16(b) of the 1934 Act by reason of such
         exercise.

                   11.  Issuer hereby represents and warrants to Grantee
         as follows:

                        (a)  Issuer has full corporate power and author-
         ity to execute and deliver this Agreement and to consummate the
         transactions contemplated hereby.  The execution and delivery
         of this Agreement and the consummation of the transactions con-
         templated hereby have been duly and validly authorized by the
         Board of Directors of Issuer and no other corporate proceedings
         on the part of Issuer are necessary to authorize this Agreement
         or to consummate the transactions so contemplated.  This Agree-
         ment has been duly and validly executed and delivered by Is-
         suer.

                        (b)  Issuer has taken all necessary corporate
         action to authorize and reserve and to permit it to issue, and
         at all times from the date hereof 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 hereun-
         der, and all such shares, upon issuance pursuant hereto, will
         be duly authorized, validly issued, fully paid, nonassessable,
         and will be delivered free and clear of all claims, liens, en-
         cumbrances, and security interests and not subject to any pre-
         emptive rights.

                   12.  Grantee hereby represents and warrants to Issuer
         that:

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

                        (b)  The Option is not being, and any shares of
         Common Stock or other securities acquired by Grantee upon exer-
         cise of the Option will not be, acquired with a view to the 





                                      - 16 -<PAGE>







         public distribution thereof and will not be transferred or oth-
         erwise disposed of except in a transaction registered or exempt
         from registration under the Securities Act.

                   13.  Neither of the parties hereto may assign any of
         its rights or obligations under this Option Agreement or the
         Option created hereunder to any other person, without the ex-
         press written consent of the other party, except that in the
         event a Subsequent Triggering Event shall have occurred prior
         to an Exercise Termination Event, Grantee, subject to the ex-
         press provisions hereof, may assign in whole or in part its
         rights and obligations hereunder within 90 days following such
         Subsequent Triggering Event (or such later period as provided
         in Section 10); provided, however, that until the date 15 days
         following the date on which the Federal Reserve Board approves
         an application by Grantee under the BHCA to acquire the shares
         of Common Stock subject to the Option, Grantee may not assign
         its rights under the Option except in (i) a widely dispersed
         public distribution, (ii) a private placement in which no one
         party acquires the right to purchase in excess of 2 percent of
         the voting shares of Issuer, (iii) an assignment to a single
         party (e.g., a broker or investment banker) for the purpose of
         conducting a widely dispersed public distribution on Grantee's
         behalf, or (iv) any other manner approved by the Federal Re-
         serve Board.

                   14.  Each of Grantee and Issuer 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 Agree-
         ment, including without limitation making application to list
         the shares of Common Stock issuable hereunder on the NASDAQ
         Stock Market National Market System upon official notice of
         issuance and applying to the Federal Reserve Board under the
         BHCA for approval to acquire the shares issuable hereunder, but
         Grantee shall not be obligated to apply to state banking au-
         thorities for approval to acquire the shares of Common Stock
         issuable hereunder until such time, if ever, as it deems ap-
         propriate to do so.

                   15.  Notwithstanding anything to the contrary herein,
         in the event that the Holder or Owner or any Related Person (as
         hereinafter defined) 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 (i)
         in the case of a Holder or any Related Person thereof, the Op-
         tion held by it shall immediately terminate and be of no fur-
         ther force or effect, and (ii) in the case of an Owner or any
         Related Person thereof, the Option Shares held by it shall be
         immediately repurchasable by Issuer at the Option Price.  A 



                                      - 17 -<PAGE>







         "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.

                   16.  The parties hereto acknowledge that damages
         would be an inadequate remedy for a breach of this Agreement by
         either party hereto and that the obligations of the parties
         hereto shall be enforceable by either party hereto through in-
         junctive or other equitable relief.

                   17.  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 in-
         valid, void, or unenforceable, the remainder of the terms, pro-
         visions, 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 rea-
         son such court or regulatory agency determines that the Holder
         is not permitted to acquire, or Issuer is not permitted to re-
         purchase pursuant to Section 7, the full number of shares of
         Common Stock provided in Section 1(a) hereof (as adjusted pur-
         suant to Section 1(b) or 5 hereof), it is the express intention
         of Issuer to repurchase such lesser number of shares as may be
         permissible, without any amendment or modification hereof.

                   18.  All notices, requests, claims, demands, and
         other communications hereunder shall be deemed to have been
         duly given when delivered in person, by cable, telegram, tele-
         copy, 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.

                   19.  This Agreement shall be governed by and con-
         strued in accordance with the laws of the State of Oregon, re-
         gardless of the laws hat might otherwise govern under appli-
         cable principles of conflicts of laws thereof.

                   20.  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.

                   21.  Except as otherwise expressly provided herein,
         each of the parties hereto shall bear and pay all costs and
         expenses incurred by it or on its behalf in connection with the
         transactions contemplated hereunder, including fees and ex-
         penses of its own financial consultants, investment bankers,
         accountants, and counsel.

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

                   23.  Capitalized terms used in this Agreement and not
         defined herein shall have the meanings assigned thereto in the
         Merger Agreement.

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