                   Notes to Consolidated Financial Statements


1.      PRINCIPLES OF CONSOLIDATION

        The accompanying 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. Bancorp was incorporated on September 18, 1996, and
became the holding company of the Bank through a merger and one-for-one share
exchange. The effective date of the merger was July 1, 1997. As a result of the
merger, Bancorp acquired 100% of the common stock of the bank, and the
shareholders of the Bank became shareholders of Bancorp.

        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 including
normal recurring accruals necessary for fair presentation of results of
operations for the interim periods included herein have been made. All financial
information has been restated for the periods shown on a consolidated basis,
including periods prior to the effective date of the merger whereby Bancorp
became the holding company of the Bank. The results of operations for the three
months and nine months ended September 30, 1997 are not necessarily indicative
of results to be anticipated for the year ending December 31, 1997.

2.      USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

        The preparation of financial statements, in conformity with generally
accepted 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 5% stock dividend on September 16,
1997 payable to Bancorp shareholders of record on October 5, 1997. As of the
merger date of July 1, 1997, $5.00 par stock of Citizens Bank was exchanged for
No Par stock of Bancorp. Accordingly, the total shareholder equity accounts
of the Bank were transferred to common stock outstanding of Bancorp as of
July 1, 1997.

All per share amounts have been restated to retroactively reflect stock

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

ORGANIZATION

        Citizens Bancorp ("Bancorp"), an Oregon corporation, is the parent
corporation and holding company of Citizens Bank (the "Bank"), which is its sole
subsidiary. The Bank is an Oregon state-chartered banking corporation with head-
quarters in Corvallis, Oregon. Bancorp was incorporated on September 18, 1996 
and became the holding company of the Bank through the merger with the Bank of 
an interim subsidiary bank established by Bancorp for that purpose. As a result
of the merger, Bancorp acquired 100% of the common stock of the Bank, and the
shareholders of the Bank became shareholders of Bancorp under a one-for-one
exchange of shares. The merger was approved by a statutory majority of the
shareholders of the Bank at the annual meeting of shareholders on April 15,
1997, and all regulatory approvals were received prior to July 1, 1997. The
effective date of the merger was July 1, 1997. The merger and the exchange of
shares thereunder was exempt from registration with the Securities and Exchange
Commission under Section 3(a)(12) of the Securities Act of 1993. As of November
11, 1997 Bancorp had 1,922,321 shares of its common stock are issued and
outstanding.

SUCCESSOR ENTITY REPORTING

        For reporting purposes, Bancorp is the successor entity to the Bank, and
Bancorp's common stock has been registered through the filing of a Form 8-A as a
precondition to its reporting under the Securities Exchange Act of 1934 in lieu
of the Bank and as the Bank's reporting successor. Through the second quarter of
1997, the Bank filed quarterly and annual statements on FDIC Forms F-2 and F-4
under Section 13 of the Securities Exchange Act of 1934 with the offices of the
Federal Deposit Insurance Corporation. This Form 10-Q is Bancorp's first
periodic report filed under the Securities Exchange Act of 1934.

OVERVIEW OF FINANCIAL RESULTS

        Bancorp reported net income of $1,015,000, or $.53 per share for the
three months ended September 30, 1997. This was a 17.61% increase in net income,
as compared to $863,000, or $.46 per share, for the three months ended September
30, 1996.

        For the nine months ended September 30, 1997, Bancorp reported net
income of $2,507,000, or $1.30 per share, a 9.3% increase in net income, as
compared to $2,292,000, or $1.21 per share, for the nine months ended September
30, 1996. The foregoing per share information is adjusted for a 2 for 1 stock
split effective October 5, 1996 and a stock dividend declared September 16,
1996.

        The increased earnings during the periods described above reflected
primarily the expansion of the Bank's interest-earning assets and increased net
interest income.

<PAGE>   10


        During the first nine months of 1997 no dividends were paid. This
resulted in an increase in shareholders equity equal to the net earnings
reported through September 30, 1997.

        In September, 1997 the Board of Directors of Bancorp declared a special
5% stock dividend payable October 5, 1997. This resulted in an increase in the
shareholder capital stock account of 91,415, and a reduction in retained
earnings of the same amount. The total of capital accounts remained the same.

</TABLE>


MATERIAL CHANGES IN FINANCIAL CONDITION

        Changes in financial condition for the nine months ended September 30,
1997 include an overall decrease in total assets. At September 30, 1997, total
assets decreased 0.489%, or approximately $938,000, over total assets at
December 31, 1996. A decrease of $4,869,000 in cash and cash equivalents, a
$3,253,000 decrease in investment securities, and a $6,461,000 increase in loans
were the major components of the change in total assets.

        The decrease in cash and cash equivalents was due primarily to
management's changes in the Bank's deposit mix in order to reduce risk. At
December 31, 1996 the Bank's liquidity position had increased to the point where
management felt it was appropriate to reduce its dependence on large liability
deposits. In December, 1996 the Bank decided not to renew two substantial
certificates of deposit held by a corporate depositor. One certificate was in
the amount of approximately $2 million, and the other was in the amount of
approximately $10 million. When these certificates expired on December 29, 1996,
the funds were moved into demand accounts and then withdrawn in the first week
of January 1997. This caused a significant reduction in total deposits in
January of 1997. Most of this reduction in certificate of deposit holdings had
been replaced by non-interest bearing demand deposits (core deposits) as of
September 30, 1997. As a general policy the Bank no longer is a competitive
bidder on interest-sensitive large liabilities.

        The increase in loans was primarily due to strong loan demand as a
result of favorable economic conditions, and to increased marketing efforts. The
Bank has hired two new lending officers in an effort to meet demand in the small
business lending market. This increase in loan activity was somewhat enhanced by
merger activity among the larger banks, which caused the closure of local
branches of merged institutions. The Bank's loan portfolio does not appear to be
reactive to seasonal fluctuations, which management believes to be the result of
the diversification of the portfolio.

        At September 30, 1997, the Bank held $1,200,000 in federal funds sold,
in comparison with zero federal funds sold for the period ending December 31,
1996. The increase in this category was due to improved federal funds rates.
Federal funds sold represents overnight investments of surplus funds, which can
fluctuate widely on a 





<PAGE>   11

day-to-day basis depending on cash needs. At December 31, 1996 the Bank had
substantial liquidity, but had a significant position in fixed rate certificates
of deposit of correspondent banks. Of the Bank's $16,380,000 in interest-bearing
deposits held at commercial banks at December 30, 1996, approximately
$12,000,000 were funded by two substantial corporate certificates of deposit. As
noted above, the Bank did not renew these certificates. As the Bank's liquidity
increased in 1997 due to an increase in non-interest bearing demand deposits,
management felt it was appropriate to hold part of this liquidity in variable
(overnight) federal funds.

        The Bank experienced a net decrease in total deposits of approximately
$3.6 million for the period ending September 30, 1997 as compared to December
31, 1996, a decrease of 2.21%. The largest single factor in this decrease was a
decline in demand deposits of $9,650,000, a decrease of nearly 22% for the
period, due to the withdrawal of approximately $12,000,000 in large liability
certificates of deposit as described above. This decrease was partially offset
by an increase in savings and interest-bearing demand deposits, which increased
by $2,584,000, or almost 3.9%. Time deposits in denominations of $100,000 or
more declined from approximately $13.9 million to $13,299,000, a decrease of
$655,000, or 4.69%. Deposits in the category of "other" increased by 11.05%, or
$4,141,000.

        Overall, management has taken steps which it believes will reduce risk
in the Bank's deposit base. Consistent with the Bank's strategy to emphasize
personal service and the development of long-term customer relationships, the
Bank has sought to increase core non-interest bearing deposits, and to reduce
its dependence on large interest-sensitive corporate deposits. Management's goal
is to reduce the volatility of its liquidity base, and to reduce the sensitivity
of its liquidity base to economic conditions.

MATERIAL CHANGES IN RESULTS OF OPERATIONS

        Total interest income increased $247,000 for the three months ended
September 30, 1997 as compared to the same three-month period in 1996. For the
nine-month period ending September 30, 1997, total interest income increased
$1,114,000, an increase of 10.89%, as compared to the same period in 1996. These
increases are primarily due to increases in loan volume and improvements in the
Bank's net interest margin. For the nine months ending September 30, 1997 total
loans grew by $6.4 million, while the Bank's net interest margin increased from
5.6% to 6.1%. The increase in the net interest margin was due to more aggressive
pricing of interest rates and loan fees.

        Total interest expense increased $47,000 for the quarter ended September
30, 1997 as compared to 1996, and $195,000 for the nine-month period ending
September 30, 1997 as compared to the same nine-month period in 1996. This
increase is primarily due to an increase in the volume of interest-bearing
accounts and increases in interest paid on deposits.



                                       11
<PAGE>   12

        The increase in interest earned, offset in part by the increase in
interest paid, served to increase the Bank's net interest income (net of
provision for loan losses) by $193,000 for the third quarter of 1997 over the
comparable quarter of 1996, and by $873,000 for the nine-month period ending
September 30, 1997 as compared to the same period in 1996. On a split-adjusted
basis, net income per share of Bancorp common stock increased to $1.30 for the
nine months ending September 30, 1997 from $1.21 per share for the same nine
period in 1996.

        Noninterest income increased approximately $59,000 for the three months
ended September 30, 1997 as compared to the same three-month period in 1996. For
the nine-month period ending September 30, 1997, the increase was $297,000 over
the same period in 1996. This increase is attributable to increases in income
generated by the increases in service charges and fees on deposit accounts, and
by other service charges, commissions and fees.

        Noninterest expense increased approximately $60,000 for the three months
ended September 30, 1997 as compared to the same three-month period in 1996. For
the nine-month period ending September 30, 1997, the increase was $703,000 over
the same period in 1996. The increase for these periods was primarily
attributable to increases in salaries and employee benefits and other
noninterest expenses. Other noninterest expenses increased primarily due to
professional expenses related to the formation of Bancorp as the holding company
for the Bank, and the initial registration of Bancorp as a reporting company
with the Securities and Exchange Commission.

        Salaries and employee benefits increased approximately $143,000, or
19.86%, during the third quarter of 1997 as compared to the 1996 third quarter.
For the nine-month period ending September 30, 1997, the increase was $373,000,
or 17.47%, over the same period in 1996. These increases were primarily due to
routine adjustments in officer and staff salaries, staffing increases in
preparation for the opening of a new branch office, and staffing increases for a
proposed expansion into a new market area.

LOAN LOSS PROVISION

        During the three months ended September 30, 1997, the Bank charged a
$45,000 loan loss provision to operations, as compared to $38,000 charged during
the same period in 1996. For the nine months ending September 30, 1997, the Bank
charged a $135,000 loan loss provision to operations, as compared to $89,000
charged during the same period in 1996. Even though there have been no loan
charge-offs in 1997 through the end of the third quarter, management feels that
a loan loss reserve of 1% of net loans is an appropriate target for this
category. To reach this level, beginning on January 1, 1997 the Bank began
increasing its expense for the loan loss reserve category to $15,000 per month
from the previous $7,500 per month. At September 30, 1997 the reserve for loan
losses was $1.173 million, or .959% of total loans.



                                       12
<PAGE>   13

        The total of loans charged off, net of loan recoveries, was zero during
the quarter ended September 30, 1997, as compared to zero for the same
three-month period in 1996. For the nine months ending September 30, 1997, loans
charged off, net of loan recoveries, was zero, as compared to zero for the same
nine-month period in 1996.

        Management believes that the reserve for loan losses is adequate for
potential loan losses, based on management's assessment of various factors,
including present delinquent and nonperforming loans, past history of industry
loan loss experience, and present and anticipated future economic trends
impacting the areas and customers served by the Bank.

LIQUIDITY AND CAPITAL RESOURCES

        Bancorp's subsidiary has adopted policies to maintain a relatively
liquid position to enable it to respond to changes in the Bank's needs and
financial environment. Generally, the Bank's major sources of liquidity are
customer deposits, sales and maturities of investment securities, the use of
federal funds markets and net cash provided by operating activities. Scheduled
loan repayments are a relatively stable source of funds, while deposit inflows
and unscheduled loan prepayments, which are influenced by general interest rate
levels, interest rates available on other investments, competition, economic
conditions and other factors, are not.

        The analysis of liquidity should also include a review of the changes
that appear in the consolidated statement of cash flows for the first nine
months of 1997. The statement of cash flows includes operating, investing and
financing categories. Operating activities include net income of $2,507,000,
which is adjusted for non-cash items and increases or decreases in cash due to
changes in certain assets and liabilities. Investing activities consisted
primarily of both proceeds from and purchases of securities, and the impact of
the net growth in loans. Financing activities present the cash flows associated
with the Bank's deposit accounts.

        At September 30, 1997, the Bank's Tier 1 and total risk-based capital
ratios under the Federal Reserve Board's ("FRB") risk-based capital guidelines
were 10.17% and 10.78%, respectively. The FRB's minimum risk-based capital ratio
guidelines for Tier 1 and total capital are 4.0% and 6.0%, respectively.

        At September 30, 1997, the Bank's capital-to-assets ratio under leverage
ratio guidelines was approximately 17.78%. The FRB's current minimum leverage
capital ratio guideline is 8.5%.

        On July 15, 1997 the Board of Directors of Bancorp approved a Dividend
Reinvestment Plan (the "Plan"). The Plan provides holders of Bancorp common
stock with a means to reinvest cash dividends otherwise payable on their shares
in additional shares of Bancorp common stock. Participants in the Plan may
automatically reinvest either 50% or 100% of the cash dividends otherwise
payable on their common stock in additional shares of common stock without fees
or transaction charges. At the time of enrollment in the Plan, a shareholder
must elect whether to apply 50% or 100% of the cash dividends otherwise payable
to the shareholder for reinvestment under the Plan. A shareholder may change
this election at any time in writing by following the procedures established for
the administration of the Plan, but a shareholder may not specify any cash
dividend reinvestment percentage other than either 50% or 100%. Bancorp will not
issue fractional shares under the Plan. Any cash dividends insufficient to
acquire a non-fractional share of Bancorp common stock shall be paid in cash to
the shareholder enrolled in the Plan. Participation in the Plan is completely
voluntary. Those holders of the Bancorp common stock who do not choose to
participate in the Plan will receive cash dividends, as declared, as usual. The
Plan applies only to cash dividends, not to stock dividends or stock splits. The
Plan replaces a similar dividend reinvestment plan operated by the Bank prior to
the merger constituting Bancorp as the Bank's holding company. The key
differences between the two plans are (i) under the Bank's plan, a shareholder
could elect to invest either 50%, 75% or 100% of the dividend, rather than
either 50% or 100%, and (ii) a shareholder could receive fractional shares under
the Bank's plan. A Registration Statement on Form S-3 will be filed by Bancorp
prior to the issuance of shares under the Plan.
