                       AGREEMENT AND PLAN OF CONSOLIDATION

           AGREEMENT AND PLAN OF CONSOLIDATION, dated as of the 24th day of
  March 1998 (this "Plan"), is between GRANT NATIONAL BANK (the "Bank") and
  UNITED SECURITY BANCORPORATION ("USBN") acting on its own behalf and on behalf
  of a national banking association to be formed by it under the title NEW GRANT
  NATIONAL BANK ("New Bank").

                                    PREAMBLE

         The management and boards of directors of USBN and the Bank believe,
respectively, that the consolidation of New Bank with the Bank under the charter
of the Bank, pursuant to 12 USC Section 215(a) and the terms and conditions set
forth in this Agreement, is in the best interests of USBN and the Bank's
shareholders.

                                    RECITALS

         (A) THE BANK. The Bank is a national banking association duly organized
and existing in good standing under the laws of the United States, with its
principal executive offices located in Ephrata, Washington. As of the date of
this Agreement, the Bank has 250,000 authorized shares of common stock, $25 par
value per share ("Bank Common Stock") (no other class of capital stock being
authorized), of which 33,000 shares of Bank Common Stock are issued and
outstanding and of which 1,000 shares are Bank Options reserved for issuance.

         (B) USBN. USBN is a corporation duly organized and validly existing
under Washington law and is a registered bank holding company under the Bank
Holding Company Act of 1956, as amended. USBN's principal executive offices are
located in Spokane, Washington. As of the date of this Agreement, USBN has
15,000,000 authorized shares of common stock, no par value per share ("USBN
Common Stock") (no other class of capital stock being authorized), of which
4,052,775 shares of USBN Common Stock are issued and outstanding and of which
300,000 shares are USBN Options reserved for issuance.

         (C) NEW BANK. New Bank will be organized by persons designated by USBN
who will, upon execution of this Agreement by the Bank and USBN, apply for
preliminary approval of the Office of the Comptroller of the Currency ("OCC")
for New Bank to become a new national banking association. Upon such preliminary
approval, New Bank will become a body corporate and will execute this Agreement,
thereby becoming a party hereto and ratifying all prior actions taken on its
behalf by USBN. All of the capital stock of New Bank will be subscribed for
solely by USBN, and the consideration for such stock will be paid in before the
Effective Date.

         (D) DIRECTOR AND OFFICER AGREEMENTS. As a condition and an inducement
to USBN's willingness to enter into this Plan, the directors of the Bank have
entered into agreements in the forms attached to this Plan as Exhibit A and
Exhibit B, pursuant to which, among other things, each director has agreed to
vote his or her shares of Bank Common Stock in favor of approval of the actions
contemplated by this Plan at the Meeting (as defined below) and to refrain from
competing with USBN and the Consolidated Association (as defined below).

         (E) APPROVALS.  At meetings of the  respective  Boards of Directors of
the Bank and USBN,  each such Board has approved and authorized the execution of
this Plan in counterparts.

the Internal Revenue Code of 1986, as amended. For federal banking law purposes,

                            ARTICLE I. CONSOLIDATION

         1.1      THE CONSOLIDATION. Subject to the provisions of this Plan and
in accordance with the terms of 12 USC Sections 215(a) through 215(g) and 12 CFR
Section 5.33, on the Effective Date, New Bank will consolidate with the Bank,
under the charter of the Bank (the "Consolidation"), and the resulting
consolidated national banking association will operate under the name "Grant
National Bank" (the "Consolidated Association"). The Consolidated Association
will be a separate direct subsidiary of USBN as a result of the Consolidation.
After the Effective Date, the Board of Directors of the


                                       6
   12
Consolidated Association will consist of the directors of the Bank immediately
preceding the Effective Date plus two additional directors to be designated by
USBN.

         1.2      EFFECTIVE DATE. Unless the Parties agree upon another date,
the "Effective Date" will be the tenth business day after the fulfillment or
waiver of each condition precedent set forth in, and the granting of each
approval (and expiration of any waiting period) required by, Article VI. A
business day is any day other than a Saturday, Sunday, or legal holiday in the
State of Washington. If the Consolidation is not consummated in accordance with
this Plan on or prior to December 31, 1998, the Bank or USBN may terminate this
Plan in accordance with Article VII.

         1.3      EFFECT OF CONSOLIDATION. On the Effective Date, the corporate
existence of each of the Bank and New Bank will be merged into and continued in
the Consolidated Association. The Consolidated Association will be deemed to be
the same corporation as each of the Bank and New Bank. All rights, franchises
and interests of each of the Bank and New Bank in and to every type of property
(real, personal and mixed) and choses in action will be transferred to and
vested in the Consolidated Association by virtue the Consolidation without any
deed or other transfer. The Consolidated Association, upon the Effective Date
and without any order or other action on the part of any court or otherwise,
will hold and enjoy all rights of property, franchises, and interests in the
same manner and to the same extent as such rights, franchises and interests were
held or enjoyed by each of the Bank and New Bank immediately prior to the
Effective Date, subject to the conditions of 12 USC Sections 215(a) through
215(g).

                    ARTICLE II. CONSOLIDATION CONSIDERATION

         2.1      CONSIDERATION. Subject to the provisions of this Plan, on the
Effective Date:

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

                  (B)      OUTSTANDING BANK COMMON STOCK. Except as provided
below in Section 2.7, each share of Eligible Bank Common Stock issued and
outstanding immediately prior to the Effective Date will, by virtue of the
Consolidation, automatically and without any action on the part of the holder of
the share, be converted into the right to receive a number of shares of USBN
Common Stock determined according to a ratio (the "Exchange Ratio"). The
Exchange Ratio is the number of shares of USBN Common Stock to be exchanged for
each share of Eligible Bank Common Stock and will be calculated by dividing the
Per Share Consideration by the Average Closing Price and rounding the quotient
to two decimals (rounding down if the third decimal is four or less and rounding
up if the third decimal is five or more).

                  (C)      OUTSTANDING NEW BANK COMMON STOCK. Each share of New
Bank Common Stock issued and outstanding immediately prior to the Effective Date
will, on and after the Effective Date, remain issued and outstanding, and the
Consolidated Association will issue to USBN additional shares of the common
stock of the Consolidated Association to cause the number of shares then
outstanding to equal the number of shares of Bank Common Stock issued and
outstanding immediately prior to the Effective Date.

         2.2      SHAREHOLDER RIGHTS; STOCK TRANSFERS. On the Effective Date,
all shares, other than Dissenting Shares, of Bank Common Stock issued and
outstanding immediately prior to the Effective Date will be converted on the
Effective Date into shares of USBN Common Stock in


                                       7
   13
accordance with Section 2.1(B) by virtue of the Consolidation. After the
Effective Date, there will be no transfers on the stock transfer books of the
Bank of the shares of Bank Common Stock that were issued and outstanding
immediately prior to the Effective Date.

         2.3      FRACTIONAL SHARES. Notwithstanding any other provision of this
Plan, no fractional shares of USBN Common Stock and no certificates or scrip or
other evidence of ownership of such fractional shares, will be issued in the
Consolidation. USBN will pay to each holder of Bank Common Stock who would
otherwise be entitled to a fractional share an amount in cash determined by
multiplying such fraction by the Average Closing Price.

         2.4      EXCHANGE PROCEDURES. As promptly as practicable after the
Effective Date, USBN will send or cause to be sent to each former shareholder of
the Bank of record immediately prior to the Effective Date transmittal materials
for use in exchanging such shareholder's certificates for Bank Common Stock for
the consideration set forth in this Article II. The certificates representing
the shares of USBN Common Stock for which shares of such shareholder's Bank
Common Stock are exchanged on the Effective Date, any fractional share checks
that such shareholder will be entitled to receive, and any dividends paid on
such shares of USBN Common Stock for which the record date for determination of
shareholders entitled to such dividends is on or after the Effective Date, will
be delivered to such shareholder only upon delivery to USBN's exchange agent
(the "Exchange Agent") of the certificates representing all of such shares of
Bank Common Stock (or indemnity satisfactory to USBN and the Exchange Agent, in
their judgment, if any of such certificates are lost, stolen or destroyed). No
interest will be paid on any such fractional share checks or dividends to which
the holder of such shares will be entitled to receive upon such delivery.
Certificates surrendered for exchange by any person constituting an "affiliate"
of the Bank for purposes of Rule 145 of the Securities Act will not be exchanged
for certificates representing USBN Common Stock until USBN has received a
written agreement from such person as specified in Section 5.11.

         2.5      EXCHANGE RATIO ADJUSTMENTS. If, prior to the Effective Date,
USBN changes the number of shares of USBN Common Stock issued and outstanding as
a result of a stock split, stock dividend, recapitalization or similar
transaction (excluding increases in number due to issuances of shares upon
exercise of any outstanding USBN Options), the Exchange Ratio will be
proportionately adjusted to the extent necessary to preserve the economic terms
of the Consolidation.

         2.6      EXCEPTION SHARES. Each of the Exception Shares of Bank Common
Stock will be canceled and retired upon consummation of the Consolidation, and
no consideration will be issued in exchange for any Exception Shares.

         2.7      DISSENTING SHARES. Notwithstanding anything to the contrary in
this Plan, each Dissenting Share whose holder, as of the Effective Date of the
Consolidation, has not effectively withdrawn or lost his dissenters' rights
under 12 USC Sections 215(b) through 215(d) (the "Appraisal Laws") will not be
converted into or represent a right to receive USBN Common Stock or Consolidated
Association stock, as applicable, but the holder of such Dissenting Share will
be entitled only to such rights as are granted by the Appraisal Laws. Each
holder of Dissenting Shares who becomes entitled to payment for his Bank Common
Stock or, as applicable, Consolidated Association common stock pursuant to the
provisions of the Appraisal Laws will receive payment for such Dissenting Shares
from the Consolidated Association or USBN (but only after the amount of payment
is agreed upon or finally determined pursuant to the Appraisal Laws).

         2.8      RESERVATION OF RIGHT TO REVISE TRANSACTION. In its sole
discretion, and notwithstanding any other provision in this Plan to the
contrary, USBN or New Bank may at any 


                                       8
   14
time change the method of effecting its acquisition of the Bank; but no such
change will (A) change the amount or kind of consideration to be issued to
holders of Bank Common Stock as provided for in this Plan, or (B) adversely
affect the tax treatment to the Bank shareholders as a result of receiving such
consideration. If USBN or New Bank elects to change the method of acquisition,
the Bank will cooperate with and assist USBN and/or New Bank with any necessary
amendment to this Plan, and with the preparation and filing of such
applications, documents, instruments and notices as may be necessary or
desirable, in the opinion of counsel for USBN, to obtain all necessary
shareholder approvals and approvals of any regulatory agency, administrative
body or other governmental entity.

         2.9      OPTIONS. On the Effective Date, by virtue of the
Consolidation, and without any action on the part of any holder of an option,
each option granted by the Bank to purchase shares of Bank Common Stock ("Bank
Option") that is then outstanding and unexercised will be converted into and
become an option to purchase USBN Common Stock ("USBN Option") on the same terms
and conditions as are in effect with respect to the Bank Option immediately
prior to the Effective Date, except that (A) each such USBN Option may be
exercised solely for shares of USBN Common Stock, (B) the number of shares of
USBN Common Stock subject to such USBN Option will be equal to the number of
shares of Bank Common Stock subject to such Bank Option immediately prior to the
Effective Date multiplied by the Exchange Ratio, the product being rounded, if
necessary, up or down to the nearest whole share, and (C) the per-share exercise
price under each such USBN Option will be adjusted by dividing the per-share
exercise price of the Bank Option by the Exchange Ratio, and rounding up or down
to the nearest cent. The number of shares of Bank Common Stock that are issuable
upon exercise of Bank Options as of the date of this Plan are Previously
Disclosed in Schedule 2.9. Following the Effective Date, USBN will use its best
efforts to prepare and file with the SEC a registration statement on Form S-8
covering shares of USBN Common Stock to be issued upon the exercise of stock
options assumed by USBN pursuant to this Section 2.9.

                    ARTICLE III. ACTIONS PENDING CONSUMMATION

         Unless otherwise agreed to in writing by USBN or New Bank, the Bank
will conduct its business in the ordinary and usual course consistent with past
practice and will use its best efforts to maintain and preserve its business
organization, employees and advantageous business relationships and retain the
services of its officers and key employees identified by USBN, and the Bank,
without the prior written consent of USBN or New Bank, will not:

increase any employee benefit (including incentive or bonus payments), except
normal individual increases in regular compensation to employees in the ordinary

         3.7      BENEFIT PLANS. Except as Previously Disclosed in Schedule 3.7,

                  (B)      ORGANIZATION, STANDING AND AUTHORITY. The Bank is

authorized by all necessary corporate action of the Bank, and this Plan is a
valid and binding agreement of the Bank, enforceable against the Bank in
accordance with its terms, subject to bankruptcy, insolvency and other laws of
general applicability relating to or affecting creditors' rights and to general
equitable principles.

                  (G)      NO DEFAULTS. Subject to the approval by its

other financial reports filed or to be filed subsequent to December 31, 1997, in

did not and will not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the

Bank Financial Reports prior to the date of this Plan, and (2) for commitments

business consistent with past practice since December 31, 1997. Since December

(including any obligation or liability incurred in connection with any
acquisitions in which any form of direct financial assistance of the federal
government or any of its agencies have been provided to the Bank).

                  (J)      NO EVENTS. Except as Previously Disclosed on Schedule
4.1(J), since December 31, 1994, no event has occurred that, individually or in

(including any Regulatory Authority) are pending or, to the knowledge of its
executive officers, threatened, against it (including under the Truth in Lending
Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Community
Reinvestment Act, the Home Mortgage Disclosure Act, or any fair lending law or
other law relating to discrimination); and

                           (2)      neither it nor any of its officers,
directors, controlling persons, nor any of its properties is a party to or is
subject to any order, decree, agreement, memorandum of understanding or similar
arrangement with, or a commitment letter or similar submission to, any
Regulatory Authority charged with the supervision or regulation of depository
institutions or engaged in the insurance of deposits (including the FDIC) or the
supervision or regulation of the Bank, and it has not been advised by any such
Regulatory Authority that such Regulatory Authority is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting) any
such order, decree, agreement, memorandum of understanding, commitment letter or
similar submission.

                  (M)      COMPLIANCE WITH LAWS. Except as Previously Disclosed
in Schedule 4.1(M), the Bank:

                           (1)      is in compliance, in the conduct of its
business, with all applicable federal, state, local, and foreign statutes, laws,
regulations, ordinances, rules, judgments, orders or decrees, including the Bank
Secrecy Act, the Truth in Lending Act, the Equal Credit Opportunity Act, the
Fair Housing Act, the Community Reinvestment Act, the Home Mortgage Disclosure
Act and all applicable fair lending laws or other laws relating to
discrimination;

                           (2)      has all permits, licenses, certificates of
authority, orders, and approvals of, and has made all filings, applications, and
registrations with, federal, state, local, and foreign governmental or
regulatory bodies that are required in order to permit it to carry on its
business as it is presently conducted;

                           (3)      has received since January 1, 1994, no
notification or communication from any Regulatory Authority (including any bank,
insurance and securities regulatory authorities) or its staff (1) asserting a
failure to comply with any of the statutes, regulations or ordinances that such
Regulatory Authority enforces, (2) threatening to revoke any license, franchise,
permit or governmental authorization, or (3) threatening or contemplating
revocation or limitation of, or that would have the effect of revoking or

                                       13
   19
                  (N)      MATERIAL CONTRACTS. Except as Previously Disclosed in
Schedule 4.1(N), neither the Bank nor its assets, businesses or operations, is a
party to, or bound or affected by, or receives benefits under, any material
contract or agreement or amendment to such contract or agreement. The Bank is
not in default under any contract, agreement, commitment, arrangement, lease,
insurance policy or other instrument to which it is a party, by which its
assets, business or operations may be bound or affected or under which it or its
respective assets, business or operations receives benefits, and there has not
occurred any event that, with the lapse of time or the giving of notice or both,
would constitute such a default. Except as Previously Disclosed in Schedule
4.1(N), the Bank is not subject to or bound by any contract containing covenants
that limit the ability of the Bank to compete in any line of business or with
any Person or that involve any restriction of geographical area in which, or
method by which, the Bank may carry on its business (other than as may be
required by law or any applicable Regulatory Authority).

                  (O)      REPORTS. Since January 1, 1993, the Bank has filed
all reports and statements, together with any required amendments, that it was
obligated to file with (1) the OCC, (2) the FDIC, and (4) any other Regulatory
Authorities having jurisdiction over the Bank. As of their respective dates (and
without giving effect to any amendments or modifications filed after the date of
this Plan with respect to reports and documents filed before the date of this
Plan), each of such reports and documents, including the financial statements,
exhibits and schedules to the financial statements, complied with all of the
statutes, rules and regulations enforced or promulgated by the Regulatory
Authority with which they were filed and did not contain any untrue statement of
fact or omit to state any fact necessary in order to make the statements, in
light of the circumstances under which they were made, not misleading.

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

                  (Q)      EMPLOYEE BENEFIT PLANS.

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

                           (2)      All "employee benefit plans" within the
meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), other than "multiemployer plans" within the meaning of
Section 3(37) of ERISA ("Multiemployer Plans"), covering employees or former
employees of the Bank (the "ERISA Plans"), to the extent subject to ERISA, are
in substantial compliance with ERISA. Except as Previously Disclosed in Schedule
4.1(Q)(2) each ERISA Plan which is an "employee pension benefit plan" within the
meaning of Section 3(2) of ERISA ("Pension Plan") and which is intended to be
qualified under Section 401(a) of the Internal Revenue Code of 1986 (as amended,
the "Code") has received a favorable determination letter from the Internal
Revenue Service, and the Bank is not aware of any circumstances reasonably
likely to result in the revocation or denial of


                                       14
   20
any such favorable determination letter or the inability to receive such a
favorable determination letter. There is no material pending or, to its
knowledge, threatened litigation relating to the ERISA Plans. The Bank has not
engaged in a transaction with respect to any ERISA Plan that could subject the
Bank to a tax or penalty imposed by either Section 4975 of the Code or Section
502(i) of ERISA.

                           (3)      No liability under Subtitle C or D of Title
IV of ERISA has been or is expected to be incurred by the Bank with respect to
any ongoing, frozen or terminated "single-employer plan," within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by it, or the
single-employer plan of any entity which is considered one employer with the
Bank under Section 4001(a)(15) of ERISA or Section 414 of the Code (an "ERISA
Affiliate"). The Bank does not presently contribute to a Multiemployer Plan, nor
has it contributed to such a plan within the past five calendar years. No notice
of a "reportable event," within the meaning of Section 4043 of ERISA for which
the 30-day reporting requirement has not been waived, has been required to be
filed for any Pension Plan or by any ERISA Affiliate within the past 12-month
period.

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

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

                           (6)      The Bank has no obligations for retiree
health and life benefits under any plan, except as set forth in Schedule
4.1(Q)(6). There are no restrictions on the rights of the Bank to amend or
terminate any such plan without incurring any liability under the plan.

                           (7)      Except as Previously Disclosed in Schedule
4.l(Q)(7), neither the execution and delivery of this Plan nor the consummation
of the transactions contemplated by this Plan will (a) result in any payment
(including severance, unemployment compensation, golden parachute or otherwise)
becoming due to any director or any employee of the Bank under any Compensation
and Benefit Plan or otherwise from the Bank, (b) increase any benefits otherwise
payable under any Compensation and Benefit Plan, or (c) result in any
acceleration of the time of payment or vesting of any such benefit.

                  (R)      NO KNOWLEDGE. The Bank knows of no reason why the
regulatory approvals referred to in Section 6.1 will not be obtained.

                  (S)      LABOR AGREEMENTS. The Bank is neither a party to nor
bound by any collective bargaining agreement, contract or other agreement or
understanding with a labor union or labor organization, nor is the Bank the
subject of a proceeding asserting that it has committed an unfair labor practice
(within the meaning of the National Labor Relations Act) or seeking to compel it
to bargain with any labor organization as to wages and conditions of employment,
nor is there any strike or other labor dispute involving it pending or, to the
best of its knowledge, threatened, nor is it aware of any


                                       15
   21
activity involving its employees seeking to certify a collective bargaining unit
or engaging in any other organization activity.

                  (T)      ASSET CLASSIFICATION. The Bank has Previously
Disclosed in Schedule 4.1(T) a list, accurate and complete in all material
respects, of the aggregate amounts of loans, extensions of credit or other
assets of the Bank that have been classified by it as of December 31, 1997 (the
"Asset Classification"); and no amounts of loans, extensions of credit or other
assets that have been classified as of December 31, 1997 by any regulatory
examiner as "Other Loans Specially Mentioned," "Substandard," "Doubtful" "Loss,"
or words of similar import are excluded from the amounts disclosed in the Asset
Classification, other than amounts of loans, extensions of credit or other
assets that were charged off by the Bank prior to December 31, 1997.

                  (U)      ALLOWANCE FOR POSSIBLE LOAN LOSSES. The allowance for
possible loan losses shown on the consolidated balance sheets in the December
31, 1997, Bank Financial Reports and the December 31, 1997, Bank Regulatory
Reports was, and the allowance for possible loan losses to be shown on
subsequent Bank Financial Reports was and will be, adequate in the opinion of
the Board of Directors of the Bank to provide for possible losses, net of
recoveries relating to loans previously charged off, on loans outstanding
(including accrued interest receivable) as of the dates noted.

                  (V)      INSURANCE. The Bank has taken all requisite action
(including the making of claims and the giving of notices) pursuant to its
directors' and officers' liability insurance policy or policies in order to
preserve all rights under the policy or policies. Set forth in Schedule 4.l(V)
is a list of all insurance policies maintained by or for the benefit of the Bank
and its directors, officers, employees or agents.

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

                  (X)      TAKEOVER LAWS, ARTICLES OF ASSOCIATION. The Bank has
taken all necessary action to exempt this Plan and the transactions contemplated
by this Plan from, and this Plan and such transactions are exempt from (1) any
applicable takeover laws, and (2) any takeover-related provisions of the Bank's
articles of association.

                  (Y)      NO FURTHER ACTION. The Bank has taken all action so
that the entering into of this Plan and the consummation of the transactions
contemplated by this Plan (including the Consolidation) or any other action or
combination of actions, or any other transactions, contemplated by this Plan do
not and will not (1) require a vote of shareholders (other than as set forth in
Section 6.1), or (2) except as Previously Disclosed in Schedule 4.1(Y), result
in the grant of any rights to any Person under the articles of association,
charter or bylaws of the Bank or under any agreement to which the Bank is a
party, or (iii) restrict or impair in any way the ability of the other Parties
to exercise the rights granted under this Plan.

                  (Z)      ENVIRONMENTAL MATTERS.

                           (1)      To the Bank's knowledge, the Participation
Facilities and the Loan/Fiduciary Properties are, and have been, in compliance
with all Environmental Laws.

                           (2)      There is no proceeding pending or, to the
Bank's knowledge, threatened before any court, governmental agency or board or
other forum in which the Bank or any Participation 


                                       16
   22

be expected to be, named as a defendant or potentially responsible party (a) for
alleged noncompliance (including by any predecessor) with any Environmental Law,
or (b) relating to the release or threatened release into the environment of any
Hazardous Material, whether or not occurring at or on a site owned, leased or
operated by the Bank or any Participation Facility, except for such proceedings
pending or threatened that have been Previously Disclosed in Schedule 4.1(Z)(2).

                           (3)      There is no proceeding pending or, to the
Bank's knowledge, threatened before any court, governmental agency or board or
other forum in which any Loan/Fiduciary Property (or the Bank in respect of any
Loan/Fiduciary Property) has been, or with respect to threatened proceedings,
reasonably would be expected to be, named as a defendant or potentially
responsible party (a) for alleged noncompliance (including by any predecessor)
with any Environmental Law, or (b) relating to the release or threatened release
into the environment of any Hazardous Material, whether or not occurring at or
on a Loan/Fiduciary Property, except for such proceedings pending or threatened

                           (4)      To the Bank's knowledge, there is no
reasonable basis for any proceeding of a type described in subparagraph (2) or

except for such releases that have been Previously Disclosed in Schedule
4.1(Z)(5).

                           (6)      To the Bank's knowledge, prior to the period

New Bank will be, duly qualified to do business and in good standing in the
States of the United States and foreign jurisdictions where the failure to be

case of New Bank, will have, in effect all federal state, local, and foreign
governmental authorizations necessary for it to own or lease its properties and
assets and to carry on its business as it is now or may be conducted.

                  (J)      REPORTS. Since December 31, 1994, each of USBN and
its Subsidiaries has filed all reports and statements, together with any
amendments required to be made with respect thereto, that it was required to
file with (1) the FDIC, (2) the Federal Reserve Board, and (3) any other
Regulatory Authorities having jurisdiction with respect to USBN and its
Subsidiaries. As of their respective dates (and without giving effect to any
amendments or modifications filed after the date of this Plan with respect to
reports and documents filed before the date of this Plan), each of such reports
and documents, including the financial statements, exhibits and schedules
thereto, complied in all material respects with all of the statutes, rules and
regulations enforced or promulgated by the Regulatory Authority with which they
were filed and did not contain any untrue statement of fact or omit to state any
fact necessary in order to make the statements made, in light of the
circumstances under which they were made, not misleading.

                  (K)      ACCURACY OF INFORMATION. The statements with respect
to USBN and its Subsidiaries and New Bank contained in this Plan, the Schedules
and any other written documents executed and delivered by or on behalf of USBN
or any other Party pursuant to the terms of this Plan are true and correct, and
such statements and documents do not omit any material fact necessary to make
the statements, in light of the circumstances under which they were made, not
misleading.

                  (L)      ABSENCE OF UNDISCLOSED LIABILITIES. Neither USBN nor
any of its Subsidiaries has any obligation or liability (contingent or
otherwise) except (1) as reflected the USBN Financial Reports prior to the date
of this Plan, and (2) for commitments and obligations made, or liabilities
incurred, in the ordinary course of business consistent with past practice since
December 31, 1997. Since December 31, 1997, neither USBN nor any of its
Subsidiaries has incurred or paid any obligation or liability (including any
obligation or liability incurred in connection with any acquisitions in which
any form of direct financial assistance of the federal government or any of its
agencies have been provided to any Subsidiary) that, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect on it.

         4.3      EXCEPTIONS TO REPRESENTATIONS.

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

                           (1)      no exception is required to be set forth in
a Schedule if its absence would not result in the related representation being
found untrue or incorrect under the standard established by Section 4.3(B); and

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

                  (B)      NATURE OF EXCEPTIONS. No representation contained in
this Article IV will be found untrue or incorrect and no party to this Plan will
have breached a representation due to the 


                                       20
   26
following: the existence of any fact, set of facts, or event, if the fact or
event individually or taken together with other facts or events would not, or,
in the case of Article IV is not reasonably likely to, have a Material Adverse
Effect with respect to such party.

                              ARTICLE V. COVENANTS

         The Bank hereby covenants to USBN and New Bank, and USBN and New Bank
each hereby covenants to the Bank, that:

         5.1      BEST EFFORTS. Subject to the terms and conditions of this Plan
and to the exercise by its Board of Directors of such Board's fiduciary duties,
it will use its best efforts in good faith to take, or cause to be taken, all
actions, and to do, or cause to be done, all things necessary, proper or
desirable, or advisable under applicable laws, so as to permit consummation of
the Consolidation as soon as practicable and to otherwise enable consummation of
the transactions contemplated by this Plan and will cooperate fully with the
other Parties to that end (it being understood that any amendments to the
Registration Statement or a resolicitation of proxies as a consequence of a USBN
Transaction will not violate this covenant).

         5.2      THE PROXY. The Bank will promptly assist USBN in the
preparation of a proxy statement (the "Proxy Statement") to be mailed to the
holders of the Bank Common Stock in connection with the transactions
contemplated by this Plan and to be filed by USBN in a registration statement
(the "Registration Statement") with the SEC as provided in Section 5.8, which
will conform to all applicable legal requirements, and it will call a meeting
(the "Meeting") of the holders of Bank Common Stock to be held as soon as
practicable for purposes of voting upon the transactions contemplated by this
Plan and the Bank will use its best efforts to solicit and obtain votes of the
holders of Bank Common Stock in favor of the transactions contemplated by this
Plan and, subject to the exercise of its fiduciary duties, the Board of
Directors of the Bank will recommend approval of such transactions by such
holders.

         5.3      REGISTRATION STATEMENT -- COMPLIANCE WITH SECURITIES LAWS.
When the Registration Statement or any post-effective amendment or supplement to
the Registration Statement becomes effective, and at all times subsequent to
such effectiveness, up to and including the date of the Meeting, such
Registration Statement, and all amendments or supplements thereto, with respect
to all information set forth therein furnished or to be furnished by or on
behalf of the Bank relating to the Bank and by or on behalf of USBN relating to
USBN or its Subsidiaries, (A) will comply in all material respects with the
provisions of the Securities Act and any other applicable statutory or
regulatory requirements, and (B) will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements contained therein not misleading. But, no Party
will be liable for any untrue statement of a material fact or omission to state
a material fact in the Registration Statement made in reliance upon, and in
conformity with, written information concerning another Party furnished by or on
behalf of such other Party specifically for use in the Registration Statement.

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


                                       21
   27
         5.5      PRESS RELEASES. The Bank will not, without the prior approval
of USBN, and neither USBN nor New Bank will, without the prior approval of the
Bank, issue any press release or written statement for general circulation
relating to the transactions contemplated by this Plan, except as otherwise
required by law.

         5.6      ACCESS; INFORMATION.

                  (A)      Upon reasonable notice, the Bank will afford USBN and
its officers, employees, counsel, accountants and other authorized
representatives, access, during normal business hours throughout the period up
to the Effective Date, to all of the properties, books, contracts, commitments
and records of the Bank and, during such period, the Bank will promptly furnish
(and cause its accountants and other agents to promptly furnish) to USBN (1) a
copy of each material report, schedule and other document filed by the Bank with
any Regulatory Authority, (2) such representations and certifications as are
necessary for purposes of the pooling letter described in Section 6.2(F), and
(3) all other information concerning the business, properties and personnel of
the Bank as USBN may reasonably request, provided that no investigation pursuant
to this Section 5.6 will affect or be deemed to modify or waive any
representation or warranty made by the Bank in this Plan or the conditions to
the obligations of the Bank to consummate the transactions contemplated by this
Plan; and

                  (B)      Neither USBN nor New Bank will use any information
obtained pursuant to this Section 5.6 for any purpose unrelated to the
consummation of the transactions contemplated by this Plan and, if this Plan is
terminated, will hold all confidential information and documents obtained
pursuant to this paragraph in confidence (as provided in Section 8.6) unless and
until such time as such information or documents become publicly available other
than by reason of any action or failure to act by USBN or New Bank or as it is
advised by counsel that any such information or document is required by law or
applicable stock exchange rule to be disclosed, and in the event of the
termination of this Plan, USBN and New Bank will, upon request by the Bank,
deliver to the Bank all documents so obtained by USBN or destroy such documents
and, in the case of destruction, will certify such fact to the Bank.

         5.7      TERMINATION FEE.

                  (A)      Without the prior written consent of USBN, the Bank
will not solicit, initiate or encourage inquiries or proposals with respect to,
or, except as required by the fiduciary duties of the Board of Directors of the
Bank (as advised in writing by its outside counsel), furnish any nonpublic
information relating to or participate in any negotiations or discussions
concerning, any acquisition or purchase of all or a substantial portion of the
assets of, or a substantial equity interest in, the Bank or any merger or other
business combination with the Bank other than as contemplated by this Plan
("Acquisition Proposal"); it will instruct its officers, directors, agents,
advisors and affiliates to refrain from doing any of the foregoing; and it will
notify USBN immediately if any such inquiries or proposals are received by, or
any such negotiations or discussions are sought to be initiated with, the Bank.

                  (B)      If (1) an Acquisition Proposal occurs prior to the
Meeting, (2) the Bank shareholder approval contemplated by Section 6.1 is not
obtained at the Meeting, and (3) prior to July 31, 1999, a Third Party acquires
control of the Bank by merger, purchase of assets, acquisition of stock or
otherwise, then unless the representations and warranties of USBN in this Plan
were false in any material respect as of the date of such Meeting or USBN was in
material default of its covenants in this Plan as of such date, the Bank will
promptly pay to USBN the amount of $350,000. For the purposes of this Subsection
(B), a Third Party will be deemed to have acquired control of the Bank when the
Third Party possesses, directly or indirectly, the power to direct or cause the
direction of the management and policies of the Bank, whether through the
ownership of voting interests, by contract, or otherwise.

Registration Statement to be declared effective as soon as practicable after the

purposes of Rule 145 under the Securities Act to execute and deliver to USBN on
or before the mailing of the Proxy Statement for the Meeting an agreement in the
form attached hereto as Exhibit C restricting the disposition of such
affiliate's shares of the Bank Common Stock and the shares of USBN Common Stock

request, modify and change its loan, litigation and other reserve and real
estate valuation policies and practices (including loan classifications and
levels of reserves), and generally conform its operating, lending and compliance
policies and procedures, immediately prior to the Effective Date so as to be
consistent on a mutually satisfactory basis with those of USBN and GAAP;
provided, however, that prior to any such modification or change, USBN will
certify that the conditions to the obligation of USBN under Section 6.1 and 6.2
to consummate the transactions contemplated by this Plan, other than the
condition set forth in Section 6.1(G), have been satisfied or waived. The Bank's
representations, warranties and covenants contained in this Plan will not be
deemed to be untrue or breached in any respect for any purpose as a consequence
of any modifications or changes undertaken pursuant to this Section 5.12.

         5.13     TAKEOVER LAW. The Bank will not take any action that would

from, or, if necessary, challenge the validity or applicability of, any
applicable takeover law.

         5.14     NO RIGHTS TRIGGERED. Except for those consents of Third
Parties Previously Disclosed on Schedule 4.1(G), the Bank will take all
necessary steps to ensure that the entering into of 


                                       23
   29
this Plan and the consummation of the transactions contemplated by this Plan
(including the Consolidation) and any other action or combination of actions, or
any other transactions contemplated by this Plan, do not and will not (A) result
in the grant of any rights to any Person under the articles of association or
bylaws of the Bank or under any agreement to which the Bank is a party, or (B)
restrict or impair in any way the ability of USBN to exercise the rights granted
under this Plan.

         5.15     SHARES LISTED. USBN will use its best efforts to cause to be

secure all necessary approvals for New Bank to become a new national banking
association and for the consummation of the Consolidation as described in this
Plan.

         5.17     REGULATORY DIVESTITURES. Effective on or before the Effective
Date, the Bank will cease engaging in such activities as USBN will advise the
Bank in writing are not permitted to be engaged in by USBN under applicable law

Authority as a condition of approval of the transactions contemplated by this
Plan, the Bank will cease engaging in any activities or holding assets that are
impermissible for USBN or its Subsidiaries, on terms and conditions agreed to by
USBN; provided, however, that prior to taking such action, USBN will certify
that the conditions to the obligations of USBN under Sections 6.1 and 6.2 to
consummate the transactions contemplated by this Plan, other than the condition
set forth in Section 6.1(G), have been satisfied or waived.

of the other.

                  (B)      Each of the Bank and USBN will promptly notify the
other of (1) any material change in the business or operations of it or its
Subsidiaries, (2) any material complaints, investigations or hearings (or
communications indicating that the same may be contemplated) of any Regulatory
Authority relating to it or its Subsidiaries, (3) the initiation or threat of
material litigation involving or relating to it or its Subsidiaries, or (4) any
event or condition that might reasonably be expected to cause any of its
representations or warranties set forth in this Plan not to be true and correct
in all material respects as of the Effective Date or prevent it or its
Subsidiaries from fulfilling its or their obligations under this Plan.

         5.19     INDEMNIFICATION.

                  (A)      For a period of four years from and after the
Effective Date, USBN will indemnify, defend and hold harmless the present and
former directors and officers of the Bank (each, an "Indemnified Party") against
all costs or expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages or liabilities incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, and arising out of matters existing or
occurring at or prior to the Effective Date (including the transactions
contemplated by this Plan), whether asserted or claimed prior to, at or after
the Effective Date, to the fullest extent that the 


                                       24
   30
Bank would have been permitted under Washington and federal law and its articles
of association or bylaws in effect on the date of this Plan to indemnify such
person (and USBN will also advance expenses as incurred to the fullest extent
permitted under applicable law so long as the person to whom expenses are
advanced provides an undertaking to repay such advances within a reasonable
period of time if it is ultimately determined that applicable law does not allow
for such indemnification).

                  (B)      Any Indemnified Party wishing to claim
indemnification under paragraph (A) of this Section 5.19, upon learning of such
claim, action, suit, proceeding or investigation, will promptly notify USBN of
the same, provided, however, that the failure so to notify will not affect the
obligations of USBN under paragraph (A) of this Section 5.19 (unless such
failure materially and adversely increases USBN's liability under such paragraph
(A)). In the event of any such claim, action, suit, proceeding or investigation
(whether arising before or after the Effective Date), (1) USBN will have the
right to assume the defense and USBN will pay all reasonable fees and expenses
of such counsel for the Indemnified Parties promptly as statements for payment
are received; provided, however, that USBN will be obligated pursuant to this
paragraph (B) to pay for only one firm of counsel for all Indemnified Parties in
any jurisdiction for any single action, suit or proceeding, (2) the Indemnified
Parties will cooperate in the defense of any such matter, and (3) USBN will not
be liable for any settlement effected without its prior written consent.

                  (C)      If USBN or any of its successors or assigns will
consolidate with or merge into any other entity and will not be the continuing
or surviving entity of such consolidation or merger or will transfer all or
substantially all of its assets to any entity, then and in each case, proper
provision will be made so that the successors and assigns of USBN will assume
the obligations set forth in this Section 5.19.

                  (D)      USBN will pay all expenses, including attorneys'
fees, that may be incurred by any Indemnified Party in enforcing the indemnity
and other obligations provided for in this Section 5.19. The rights of each
Indemnified Party under this Section 5.19 will be in addition to any other
rights such Indemnified Party may have under the articles of association or
bylaws of the Bank or under applicable Washington and federal law.

         5.20     DIRECTOR AGREEMENTS REGARDING REAL ESTATE. The main office of
the Bank (located at 261 Basin Southwest, Ephrata, Washington) and the land on

partnership consisting of seven of the Bank's directors (the "Group"). Each Bank
director who is a member of the Group agrees to cause the Group to lease the

Effective Date, except for any such representations and warranties that

                            ARTICLE VII. TERMINATION

         7.1      EVENTS OF TERMINATION. This Plan may be terminated prior to
the Effective Date, either before or after receipt of required shareholder
approvals:

                  (A)      MUTUAL CONSENT. By the mutual consent of USBN, New

majority of the members of its entire board.

                  (B)      BREACH. By USBN, New Bank, or the Bank, if its Board
of Directors so determines by vote of a majority of the members of its entire
Board, in the event of (A) a material breach by any other Party of any
representation or warranty in this Plan, which breach cannot be or has not been
cured within 30 days after written notice of the breach has been given to the
breaching Party, or (B) a material breach by any other Party of any of the
covenants or agreements in this Plan, which breach cannot be or has not been
cured within 30 days after written notice of the breach has been given to the
breaching Party.

                  (C)      DELAY. By USBN, New Bank, or the Bank, if its Board
of Directors so determines by vote of a majority of the members of the entire
board, in the event that the Consolidation is not consummated by December 31,
1998; provided, however, that no Party that is in material breach of any of the
provisions of this Plan will be entitled to terminate this Plan pursuant to this
Section 7.1(C).

                  (D)      NO SHAREHOLDER APPROVAL. By New Bank or the Bank, if
its Board of Directors so determines by a vote of a majority of the members of
its entire Board, if the shareholder approval contemplated by Section 6.1 is not
obtained at the Meeting or any adjournment(s) of the Meeting.

         7.2      CONSEQUENCES OF TERMINATION.

                  (A)      GENERAL CONSEQUENCES. Subject to Section 5.7
(Termination Fee), in the event of the termination or abandonment of this Plan
pursuant to the provisions of Section 7.1, this Plan will become void and have
no force or effect, without any liability on the part of the Parties or any of
their respective directors or officers or shareholders with respect to this
Plan.

                  (B)      OTHER CONSEQUENCES. Notwithstanding anything in this
Plan to the contrary, no termination of this Plan will relieve any party of any
liability for any breach of this Plan or for any misrepresentation under this
Plan or be deemed to constitute a waiver of any remedy available for such breach
or misrepresentation. In any action or proceeding in connection with such breach
or misrepresentation, the prevailing party will be entitled to reasonable
attorneys' fees and expenses.

                          ARTICLE VIII. OTHER MATTERS


         8.1      SURVIVAL. Only those agreements and covenants in this Plan
that by their express terms apply in whole or in part after the Effective Date
will survive the Effective Date. All other representations, warranties, and
covenants will be deemed only to be conditions of the Consolidation and will not
survive the Effective Date. If the Consolidation is abandoned and this Plan is
terminated, the provisions of Article VII will apply and the agreements of the
Parties in Sections 5.7(A), 5.7(B), 8.5 and 8.6 will survive such abandonment
and termination.

         8.2      WAIVER; AMENDMENT. Prior to the Effective Date, any provision
of this Plan may be (A) waived in writing by the Party benefited by the
provision, or (B) amended or modified at any time (including the structure of
the transactions contemplated by this Plan) by an agreement in writing among the
Parties approved by their respective Boards of Directors and executed in the
same manner as this Plan, except that, after the vote by the shareholders of the
Bank, the consideration to be received by the shareholders of the Bank for each
share of Bank Common Stock will not thereby be altered. Nothing contained in
this Section 8.2 is intended to modify USBN's rights pursuant to Section 2.8.

         8.3      COUNTERPARTS. This Plan may be executed in one or more
facsimile counterparts, each of which will be deemed to constitute an original.
This Plan will become effective when one counterpart has been signed by each
Party.

         8.4      GOVERNING LAW. This Plan will be governed by, and interpreted
in accordance with, the laws of the State of Washington, except as federal law
may be applicable.

         8.5      EXPENSES. Each Party will bear all expenses incurred by it in
connection with this Plan and the transactions contemplated by this Plan.

         8.6      CONFIDENTIALITY. Except as otherwise provided in Section
5.6(B), each of the Parties and their respective agents, attorneys and
accountants will maintain the confidentiality of all information provided in
connection herewith which has not been publicly disclosed.

         8.7      NOTICES. All notices, requests and other communications
hereunder to a "Party" will be in writing and will be deemed to have been duly

         8.8      ENTIRE UNDERSTANDING; NO THIRD PARTY BENEFICIARIES. This Plan
represents the entire understanding of the Parties with reference to
transactions contemplated by this Plan and supersedes any and all other oral or
written agreements previously made. Nothing in this Plan, expressed or implied,
is intended to confer upon any Person, other than the Parties or their
respective successors, any rights, remedies, obligations or liabilities under or
by reason of this Plan.

         8.9      BENEFIT PLANS. Upon consummation of the Consolidation, all
employees of the Bank will be deemed to be at-will employees of the Consolidated
Association except for Lawrence C. Mitson who is a party to the Employment
Agreement. From and after the Effective Date, employees of the Bank, including
Lawrence C. Mitson, will generally be entitled to employee benefit programs
that, in the aggregate, are generally no less favorable to such employees than
those presently being provided to employees of the Bank. For the purpose of
determining eligibility to participate in such plans and the vesting of benefits
under such plans (but not for the accrual of benefits under such plans), USBN
will give effect to years of service with the Bank as if such service were with
USBN or its Subsidiaries.

         8.10     HEADINGS. The headings contained in this Plan are for
reference purposes only and are not part of this Plan.

         IN WITNESS WHEREOF, the Parties have caused this instrument to be
executed in counterparts by their duly authorized officers, all as of the day
and year first above written.
