CITIZENS BANCORP
Notes to Consolidated Financial Statements (unaudited)

1. BASIS OF PRESENTATION

        The interim condensed consolidated financial statements include the
        accounts of Citizens Bancorp ("Bancorp"), a bank holding company and its
        wholly owned subsidiary, Citizens Bank ("Bank") after elimination of
        intercompany transactions and balances. Substantially all activity of
        Citizens Bancorp is conducted through its subsidiary bank.

        The interim financial statements are unaudited but have been prepared in
        accordance with generally accepted accounting principles for interim
        condensed financial statements. Accordingly, the condensed interim
        financial statements do not include all of the information and footnotes
        required by generally accepted financial statements. In the opinion of
        management, all adjustments consisting only of normal recurring accruals
        necessary for a fair presentation for the interim periods included
        herein have been made.

        The interim condensed consolidated financial statements should be read
        in conjunction with the December 31, 1999 consolidated financial
        statements, including notes there to, included in Bancorp's 1999 Annual
        Report to shareholders.

2. USE OF ESTIMATES IN THE PREPARATION OF FINANCIALS

        The preparation of financial statements, in conformity with general
        accounting principles, requires management to make estimates and
        assumptions that affect the reported amounts of assets and liabilities
        and disclosure of contingent assets and liabilities at the date of the
        financial statements and the reported amounts of revenues and expenses
        during the reporting period. Actual results could differ from those
        estimates.

3. SHAREHOLDERS EQUITY AND NET INCOME PER COMMON SHARE

        The Board of Directors declared a $.36 per share dividend to Bancorp
        shareholders of record on December 10, 1999, payable on January 10,
        2000. Through the Dividend Reinvestment Plan (DRIP) 13,539 shares were
        purchased at a price of $16.08 per share. The DRIP resulted in an
        increase of shares outstanding from 4,124,091 to 4,137,630.

        All per share amounts have been restated to retroactively reflect stock
        dividends, stock purchased and stock splits previously reported.

4. CONTINGENCIES

        Unfunded loan commitments totaled $24.7 million as of June 30, 2000 and
        $33.0 million as of December 31, 1999.

5. ACCOUNTING CHANGES

        In June 1998, the Financial Accounting Standards Board issued SFAS No.
        133, Accounting for Derivative Instruments and Hedging Activities. This
        statement establishes accounting and reporting standards for derivative
        instruments, including certain derivative instruments embedded in other
        contracts (collectively referred to as derivatives) and for hedging
        activities. It requires that an entity recognize all derivatives as
        either assets or liabilities in its balance sheet and measure those
        instruments at fair value. Under this statement, an entity that elects
        to apply hedge accounting is required to establish at the inception of
        the hedge the method it will use for assessing the effectiveness of the
        hedging derivative and the measurement approach for determining the
        ineffective aspect of the hedge. Those methods must be consistent with
        the entity's approach to managing risk. This statement is effective for
        all fiscal years beginning after June 15, 2000. The Bank had no
        derivatives as of June 30, 2000, nor does the Bank engage in any hedging
        activities. The Company does not anticipate that the adoption of SFAS
        No. 133 will have a material effect on its financial position or results
        of operations.

ITEM 2

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

In addition to historical information, this report contains certain "forward
looking statements" within the meaning of the Private Securities Litigation
Reform Act of 1995. This statement is included for the purpose of availing
Bancorp the protection of the safe harbor provisions of this Act. The forward
looking statements contained in this report are subject to factors, risks and
uncertainties that may cause actual results to differ materially from those
projected. Factors that might result in such material difference include, but
are not limited to economic conditions, the regulatory environment, rapidly
changing technology, new legislation, competitive factors, the interest rate
environment and the overall condition of the banking industry. Forward looking
statements can be identified by such words as "estimate", "believe", "expect",
"intend", "anticipate", "should", "may", "will", or other similar words or
phrases. Although Bancorp believes that the expectations reflected in such
forward looking statements are reasonable, it can give no assurances that such
expectations will prove to have been correct. Readers are therefore cautioned
not to place undue reliance on such forward looking statements, which reflect
management's analysis only as of the date of the statement. Bancorp does not
intend to update these forward looking statements other than in its periodic
filings under applicable security laws.

OVERVIEW

Citizens Bank ("the Bank") was chartered October 1, 1957 (charter #333) by the
State of Oregon as a commercial bank. Since its beginning with a single office
in Corvallis, Citizens Bank has expanded to an additional eight locations in the
four counties of Benton, Linn, Lane, and Yamhill. Branches are located in the
communities of Corvallis, Philomath, Albany, Junction City, Veneta, and
McMinnville.

Citizens Bancorp ("Bancorp"), an Oregon Corporation and bank holding company,
was formed in 1996 for the purpose of becoming the holding company of Citizens
Bank. Bancorp is headquartered in Corvallis, Oregon. Its principal business
activities are conducted through its full-service, commercial bank subsidiary,
Citizens Bank.

Bancorp operates through a two-tiered corporate structure. At the holding
company level the affairs of Bancorp are overseen by a Board of Directors
elected by the shareholders of Bancorp at the annual meeting of shareholders.
The business of the Bank is overseen by a Board of Directors elected by Bancorp,
the sole owner of the Bank. As of the date of this Form 10-Q the respective
members of the Board of Directors of the Bank and the Board of Directors of
Bancorp are identical.

Bancorp's culture focuses on the tenets of collaborative leadership, branch
autonomy, assertive business development, a positive working environment, a
commitment to the community, outstanding customer service, and relationship
banking. Management believes that a healthy culture together with a progressive
management style will result in constantly improved shareholder value.

Bancorp's primary goal is to improve shareholder value through increased
earnings while maintaining a high level of safety and soundness. Bancorp is
committed to independence and long-term performance strategies.

The long-term benefit to Bancorp of its cultural and management style is
consistent growth and development of the Bank over time. Risk levels have been
greatly reduced because of expertise in loan, investment, operational, and human

Bancorp provided the Federal Reserve Board of San Francisco its declaration to
elect to become a financial holding company, pursuant to the Gramm-Leach-Bliley
Act (GLBA) of 1999, on February 15, 2000. Bancorp received notice of approval
from the Board of Governors of the Federal Reserve System on March 13, 2000.
Bancorp has no current plan to engage in any of the financial activities
permissible for a financial holding company under the GLBA. Bancorp made its
declaration only to be prepared to take advantage of any future business
opportunities.

Bancorp reported net income of $1,838,000, or $.44 per share for the six months
ending June 30, 2000, compared to net income of $1,690,000, or $.41 per share
for the same period in 1999. The net increase is primarily attributable to an
increase in interest income from loans due to an increase in overall interest
rates and growth in loans.

It is the policy of the Bank to place loans on nonaccrual after they become 90
days past due unless the loans are well secured and in the process of
collection. The Bank may place loans that are not contractually past due or that
are deemed fully collateralized on nonaccrual status as a management tool to
actively oversee specific loans.

Loans on nonaccrual status as of June 30, 2000 and December 31, 1999 were
approximately $552,000 and $654,000 respectively. Loans past due 90 days or more
on which the Bank continued to accrue interest were approximately $153,000 at
June 30, 2000 and $73,000 at December 31, 1999. Of the $552,000 on non-accrual,
$465,000 is the guaranteed portion on one commercial loan. The Bank charged off
its portion of the loan in 1999. The Bank is actively pursuing all avenues of
collection on its collateral of inventory, accounts receivable and real estate.
Payment of the guaranteed portion is expected by year-end 2000. There were no
loans with modified terms as of June 30, 2000.

MATERIAL CHANGES IN FINANCIAL CONDITION

At June 30, 2000 total assets decreased 1.1% or approximately $2.7 million from
total assets at December 31, 1999. Major components of the change in total
assets were:

    - $12.7 million increase in total loans

    - $2.0 million decrease in investments

    - $9.4 million decrease in cash and cash equivalents


                                       8


<PAGE>   11
The increase in loans was primarily due to loan demand as a result of favorable
economic conditions, increased business development by the Bank's loan officers,
marketing of the Bank's personalized loan services and loans booked at the new
branches in West Albany and McMinnville. Net loans increased from $139.1 million
at December 31, 1999 to $151.8 million for the six-month period ending June 30,
2000. An increase of $12.7 million or 9.1 percent.

The decrease in investments was a result of management's decision to use funds
from investment maturities to fund loan growth.

Cash and due from banks decreased $8.9 million from December 31, 1999 to June
30, 2000. Funds which had been accumulated for Y2K purposes were not needed and
have been redeployed into loans during the six month period. At June 30, 2000
and December 31, 1999 the Bank kept its liquid excess funds in an interest
bearing demand account held at the Federal Home Loan Bank of Seattle (FHLB). The
balance at the FHLB at June 30, 2000 was $2.4 million. This account balance can
fluctuate widely on a day to day basis.

The Bank experienced a net increase in total deposits to $195.9 million at June
30, 2000 from $194.4 million at December 31, 1999 which represents an increase
of $1.5 million or .81 percent. The net increase in total deposits was the
result of an overall increase in the number of account relationships and
increases in the balances in interest bearing demand accounts. The increase in
new account relationships is a result of the Bank's business development
activities.

Long-term borrowings from the FHLB are utilized to fund and match large
long-term commercial loans. Net long-term borrowings decreased by $3.0 million
for the period ending June 30, 2000 as compared to year-end December 31, 1999.
This decrease was a result of the early payoff of loans at the FHLB without a
prepayment penalty. The Bank currently has $3.0 million in overnight borrowings
from the FHLB and $16.5 in repurchase agreements and other short term
borrowings, an increase of $1.0 million from December 31, 1999.

MATERIAL CHANGES IN RESULTS OF OPERATIONS

The Company reported net income of $1,838,000 or $.44 per share, for the six
months ended June 30, 2000, compared to net income of approximately $1,690,000,
or $.41 per share for the same period in 1999. This represents an increase in
net income of $148,000 or 8.8 percent. The net increase was primarily
attributable to an increase in interest income from loans.

Total interest income increased approximately $570,000 for the six months ended
June 30, 2000 as compared to the same 1999 period. This increase was due to
increases in interest income on loans due to volume and higher net interest
rates on the loan portfolio.

Net interest income after provision for credit losses increased $500,000 or 9.5
percent for the six months ending June 30, 2000. The increase in net interest
income is primarily from loan volume and higher interest rates on loans compared
to the same period in 1999. The increase in interest expense is due to the
volume of interest bearing liabilities as the Bank's cost of funds decreased
from the comparable period in 1999.

Non-interest income increased approximately $98,000 for the six months ended
June 30, 2000 as compared to the same six-month period in 1999. These increases
are mainly attributable to an increase in the volume of bankcard services over
last year for the same period.

Salaries and employee benefits increased approximately $96,000 (4.6%) for the
six-month period ending June 30, 2000 compared to the same six-month period in
1999. These increases were primarily due to routine adjustments in officer and
staff salaries, staff increases due to the new West Albany and McMinnville
Branches, and technical support staff.

Other non-interest expense excluding salaries and employee benefits increased
approximately $214,000 (12.0%) for the six months ended June 30, 2000 as
compared to the same six-month period in 1999. This increase was primarily due
to increases in expense relative to growth of the merchant bankcard and debit
card products, an increase in depreciation expense for the new branch buildings,
furniture and equipment, and the computer network.

CREDIT LOSS PROVISION

The Bank maintains an allowance for credit losses on loans that occur from time
to time as an incidental part of the business of banking. Loans are charged
against this allowance for credit losses which is adjusted periodically to
reflect changing loan volumes, risk potential in the portfolio and general
economic conditions. Additions to the allowance for credit losses are made
through a charge against income.

During the first six months ended June 30, 2000 the Bank funded the allowance
for credit losses $178,000 from operations as compared to $132,000 for the same
six-month period of 1999. The Bank is increasing the monthly provision for
credit losses based on its loan loss reserve analysis derived from the loan
grading system. The Bank experienced $25,000 in credit losses and $62,000 in
recoveries for the six months ended June 30, 2000 and $31,000 in credit losses
for the same period ended June 30, 1999. Historically, the Bank's loan
charge-off levels have been very low compared to its peers. Management believes
that the allowance for credit losses at June 30, 2000 of $1,286,000 or .84% of
total loans is adequate.

The provision for credit losses represents charges made to operating expenses to
maintain an appropriate allowance for credit losses. Management considers
various factors in establishing an appropriate allowance. These factors include
an assessment of the financial condition of the borrower, a determination of the
borrowers ability to service the debt from cash flow, a conservative assessment
of the value of the underlying collateral, the condition of the specific
industry of the borrower, the economic health of the local community, a
comprehensive analysis of the levels and trends of loan types, and a review of
past due and classified loans.

It is Bank policy that once each quarter, Bank management makes recommendations
to the Board regarding the adequacy of the Bank's allowance for credit losses
and the amount of the provision that should be charged against earnings for the
next three months. Management's recommendations are based on an internal loan
review process to determine specific potential loss factors on classified loans,
risk factor of loan grades, historical loss factors derived from actual net
charge-off experience, trends in non-performing loans and other potential risks
in the loan portfolio such as industry concentration, the local economy and the
volume of loans.

Management uses a loan grading system wherein loan officers assign a risk grade
to each of their loans at inception and at intervals based on receipt of
financial information, renewal, or when there is an indication that a credit may
have improved or weakened. The risk grades in the loan portfolio are used in
determining a factor that is used in analyzing the adequacy of the reserve for
credit losses.

The Bank's policy is to charge off loans when, in management's opinion, the loan
or a portion of the loan is deemed uncollectible following a concerted
collection effort. Management continues to pursue collection after a loan is
charged-off until all possibilities for collection have been exhausted.

LIQUIDITY AND CAPITAL RESOURCES

Bancorp's subsidiary, the Bank, has adopted policies to maintain a relatively
liquid position to enable it to respond to changes in the Bank's financial
environment. Generally, the Bank's major sources of liquidity are customer
deposits, sales and maturities of securities, the use of borrowing lines with
correspondent banks including Federal Home Loan bank borrowings, loan repayments
and net cash provided by operating activities.

The analysis of liquidity should also include a review of the changes that
appear in the consolidated statement of cash flows for the first six months of
2000. The statement of cash flows includes operating, investing and financing
categories. Operating activities include net income which is adjusted for
non-cash items and increases or decreases in cash due to certain changes in
assets and liabilities. Investing activities consist primarily of both proceeds
from maturities and purchases of securities, and the net growth in loans.
Financing activities present the cash flows associated with the Bank's deposit
accounts.

Management believes that the Bank's existing sources of liquidity will enable
the Bank to fund its requirements in the normal course of business.

As of June 30, 2000, shareholders' equity totaled $26,274,000 as compared to
$24,342,000 at December 31, 1999, an increase of 7.9%. This increase in equity
was primarily due to the Company's net income.

ITEM 3. QUANTITATIVE & QUALITATIVE ANALYSIS ABOUT MARKET RISK

Interest rate, credit, and operations risks are the most significant market
risks impacting the Bank's performance. The Bank relies on loan review, prudent
loan underwriting standards and an adequate allowance for credit losses to
mitigate credit risk.

The Bank uses an asset/liability management simulation model to measure interest
rate risk. The model quantifies interest rate risk through simulating forecasted
net interest income over a 12 month time period under various rate scenarios, as
well as monitoring the change in the present value of equity under the same rate
scenarios. The present value of equity is defined as the difference between the
market value of current assets less current liabilities. By measuring the change
in the present value of equity under different rate scenarios, management is
able to identify interest rate risk that may not be evident in simulating
changes in forecasted net interest income.

The Bank is currently slightly asset sensitive, meaning that interest earning
assets mature or reprice more quickly than interest-bearing liabilities in a
given period. An increase or decrease in market rates of interest will not
materially impact net interest income.

It should be noted that the simulation model does not take into account future
management actions that could be undertaken if there were a change in actual
market interest rate during the year. Also, certain assumptions are required to
perform modeling simulations that my have significant impact on the results.
These include assumptions regarding the level of interest rates and balance
changes on deposit products that do not have stated maturities. These
assumptions have been developed through a combination of industry standards and
future expected pricing behavior. The model also includes assumptions about
changes in the composition or mix of the balance sheet. The results derived from
the simulation model could vary significantly by external factors such as
changes in the prepayment assumptions, early withdrawals of deposits and
competition. Management has assessed these risks and believes that there has
been no material change since December 31, 1999.
