                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - Organization

The accompanying financial statements reflect the operations of VRB Bancorp and
its wholly owned subsidiary, Valley of the Rogue Bank.

NOTE 2 - Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information, and in compliance with instructions to Form 10-Q and Rule
10-01 of Regulation S-X. Adjustments to the interim financial statements are of
a normal recurring nature and include all adjustments that, in the opinion of
management, are necessary to the fair presentation of the financial position and
operating results for the interim periods. The consolidated financial statements
should be read in conjunction with the consolidated financial statements and
notes thereto, together with management's discussion and analysis of financial
condition and results of operations, contained in the Bank's 1998 Annual Report
to Shareholders. The operating results for the three months ended March 31,
1999, are not necessarily indicative of the results that may be expected for the
entire fiscal year ending December 31, 1999, or any other future interim period.


NOTE 3 - Earnings per common and common equivalent shares

In 1997, the FASB issued SFAS No. 128, "Earnings per share" which is effective
for financial statements issued for periods ending after December 15, 1997. SFAS
No. 128 replaced standards for computing and presenting earnings per share and
requires a dual presentation of basic and diluted earnings per share. Basic
earnings per share excludes dilution and is computed by dividing income
available to common stockholders by the weighted average number of common shares
outstanding for the period. Diluted earnings per share reflect the potential
dilution that could occur if common shares were issued pursuant to the exercise
of options under the Company's stock option plans.

NOTE 4 - Recently issued accounting standards

In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
130 "Reporting Comprehensive Income." This Statement establishes standards for
reporting comprehensive income and its components (revenues, expenses, gains,
and losses) in a full set of financial statements. This Statement requires that
VRB recognize the unrealized gain or loss on available-for-sale securities as a
component of comprehensive income. This Statement is effective for the year
ended December 31, 1998.

NOTE 5 - Acquisition of Colonial Banking Company

VRB Bancorp completed its acquisition of Colonial Banking Company (herein
referred to as "CBC") effective January 5, 1998. VRB paid former shareholders of
CBC $15.7 million in cash for the common and preferred stock of CBC. This
acquisition was treated as a purchase for accounting purposes. Accordingly,
under generally accepted accounting principles, the assets and liabilities of
CBC have been recorded at their respective fair market values at the time of
acquisition. Goodwill, the excess of the purchase price over the net fair value
of the assets and liabilities acquired, was recorded at $9.5 million.
Amortization of goodwill over a 15 year period will result in a charge to
earnings of approximately $635,000 per year.

The following are the fair values of assets acquired and liabilities assumed (in
thousands):

PART I - FINANCIAL INFORMATION

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

INTRODUCTION

VRB Bancorp was organized in 1983 under Oregon law for the purpose of becoming a
holding company of Valley of the Rogue Bank, an Oregon state chartered bank
organized in 1967. The Company conducts its business through, and has no
material operations outside of, Valley of the Rogue Bank. Accordingly, reference
to "VRB", "the Company", and "the Bank", are intended to denote VRB Bancorp and
Valley of the Rogue Bank as a consolidated entity.

MATERIAL CHANGES IN THE RESULTS OF OPERATIONS
FOR THE THREE MONTHS ENDED MARCH 31, 1999 AND 1998

Earnings per share

Earnings for the three months ended March 31, 1999 increased slightly over the
same period in 1998, from $1, 242,000 in 1998 to $1,250,000 in 1999. On a per
share basis, earnings remained consistent at $.14 per share.

Interest margin

1.      Interest rate environment: monetary policy and changing interest rates
        over the last 12 months have placed increasing pressure on the rates
        that the Bank can competitively offer on loan and deposit products.
        Local competitive forces, including new entrants to the market, and
        competition from non traditional banks have further compounded tight
        margins. As a result, maturing loans and investments have typically
        re-priced at lower rates and the Bank's overall yield on interest
        earning assets has declined from 8.99% to 8.18% (on a tax equivalent
        basis) when comparing the 1st quarter of 1999 to the same quarter in
        1998.



                                       9
<PAGE>   12

2.      Changing loan balances: loan balances averaged 74% of interest earning
        assets in the first quarter of 1998, compared to 65% for the same period
        in 1999, an approximate difference of $28 million in loans. Much of the
        loan run off relates to loans acquired from CBC. At the time of
        acquisition, at least one quarter of its loan portfolio originated from
        the Portland metropolitan area, in short-term construction and
        commercial loans. Segments of this portfolio had scheduled maturity
        dates in 1998. In addition, high competition and low interest rates
        available in that market encouraged several borrowers to refinance their
        credit obligations under terms that the Bank was unwilling to match.

3.      Changing deposit mix: when comparing the two quarters, the Bank's
        deposit mix changed significantly. The Bank experienced declining
        concentrations in time certificates of deposits, in part replaced by
        growth in non interest demand deposits and money market accounts. For
        example, time certificates of deposit declined by $16 million over the
        last twelve months, representing maturing accounts originating from the
        CBC deposit base. The shift in the Bank's deposit mix contributed to a
        favorable declining cost of funds, which moved from 3.01% to 2.40% when
        comparing the two periods.

The above discussion is supported in the following analysis of the Bank's
interest margin (on a tax equivalent basis) for the period ended March 31, 1999
and 1998:

In total, net interest income declined slightly, from $4.2 million for the three
months ended March 31, 1998 to $4.0 million for the same period in 1999. By
effectively managing the cost of its funding sources (deposits), the Bank has
been able to significantly offset unfavorable changes in both asset yields and
loan volumes, as further illustrated in the following table:

Management expects price competition to continue or increase, and rates on new
and refinanced loans will most likely reflect this environment. Loan demand has
improved, and remains the focus of the Bank's outside calling efforts and
advertising programs. Deposit strategies, designed to place downward pressure on
the Bank's average cost of funds, will be adjusted as needed to accommodate loan
demand and bank liquidity.(1)

Noninterest income and expense

Noninterest income year to date was $511,000, an increase of $42,000 or 9%, from
the same period in 1998. In particular, processing fees for mortgage
applications grew by approximately $38,000, when comparing the two periods. The
housing market has continued to expand at a robust rate in southern Oregon,
supported by low interest rates and expanding populations seeking
family-orientated communities. The Bank will continues to seek opportunities to
expand noninterest sources of revenue, which are generally less sensitive to
changing interest rates.(1)

Noninterest expense declined by $168,000, or 6%, down to $2,439,000 from
$2,608,000 for the three months ended March 31, 1999 and 1998, respectively. 60%
of the decline represents the recovery of an operational loss originally
recognized by the Bank in the 4th quarter of 1998. Administrative expenses also

declined slightly, centered around reductions in professional fees and other
one-time costs related to the acquisition and integration of CBC.

The Bank's efficiency ratio, or noninterest expense as a percentage of total net
interest income plus noninterest income, was 55% for the three months ended
March 31, 1999 verses 57% for the same period in 1998. While this comparison is
slightly skewed by the Bank's one time operational recovery described
previously, certain operating economies have been realized as a result of the
CBC acquisition. To illustrate further, after eliminating the amortization of
intangible assets directly related to the CBC merger and the one time recovery,
the Bank's current efficiency margin is reduced to approximately 53%. This is a
favorable comparison when compared to the Bank's historical averages of 56%
experienced prior to the acquisition of CBC.

MATERIAL CHANGES IN FINANCIAL CONDITION

LIQUIDITY REVIEW

The Bank must maintain cashflows adequate to fund operations and meet
commitments on a timely and cost effective basis. Fundamental to the management
of liquidity is the coordination of the different maturities of the Bank's
assets and liabilities, while maintaining enough liquidity at all times to fund
sudden loan growth and deposit withdrawals.

The liquid assets of the Bank include cash and due from banks, interest bearing
deposits in other banks, and federal funds sold. As of March 31, 1999, liquid
assets made up 10% of total bank assets. In addition, the Bank has approximately
$56 million in available-for-sale securities that can be sold to accommodate
changing liquidity needs as well as multiple funding sources with the FHLB of
Seattle and other large banks.

For the first three months of 1999, the ongoing operations of the Bank resulted
in cash outflows (cash and federal funds) of close to $10 million. The change in
the Bank's liquidity represents net loan growth of $3 million, and deposit run
off of $7 million.

CAPITAL MANAGEMENT

As of March 31, 1999, shareholders' equity totaled $35,176,000, a decrease of
$60,000 when compared to total shareholders' equity as of the end of the
previous fiscal year. The decline in shareholders' equity reflects the Board of
Directors recent decision to declare a $.12 per share cash dividend, payable May
21, 1999. The dividend, when paid, will total approximately $1.0 million.

The Bank is required to maintain minimum amounts of capital to "risk weighted"
assets, as defined by banking regulators. At March 31, 1999, the Bank was
required to have Tier 1 and Total Capital ratios of 4.0% and 8.0%, respectively.
The Bank's actual ratios at that date were 12.8% and 14.1%, respectively.

CONTINGENCIES

Year 2000 - Management continues to monitor the impact of Year 2000 on the
Bank's data processing and proprietary systems, as well as the Bank's
vulnerability to the principal borrowers of the Bank and their

potential failure to address their own Year 2000 issues. As described in the
Company's most recent 10-K regulatory filing, VRB remains on schedule in
relation to its action plan which was designed to meet established timelines and
key milestones outlined in interagency statements issued by the Federal
Financial Institutions Examination Council. Below is a brief analysis of the
various phases of the Bank's Year 2000 action plan, and the progress made to
date:

    Assessment: All information technology supported systems and products have
    been identified and evaluated. Significant borrowers of the Bank have been
    contacted to build year 2000 awareness and encourage early solutions
    regarding potential business interruption due to system failures.

    Third party evaluation and remediation: Third party confirmation of Year
    2000 compliance has been received by critical outside vendors that support
    non-information technology systems such as embedded chips.

    Integrated testing: Integrated testing and validation of the Bank's critical
    data processing systems was completed in December of 1998. Testing of other
    various stand alone systems is presently ongoing.

    Contingency planning: VRB is currently drafting a contingency plan in the
    event that its business operations are materially impacted by the turn of
    the century. Sections of the plan include the Bank's preparation for
    unprecedented customer withdrawals leading up the Year 2000, security of the
    Bank's employees, customers and funds, strategies to accommodate extended
    power loss, and failure of our data processing system due to circumstances
    beyond our control.

As of March 31, 1999, neither the Company's integrated testing of critical
systems, nor the Bank's ongoing contingency planning, has revealed any
circumstances that would cause management to believe that Year 2000 will have a
material financial impact on the performance of the Bank. To date, the Bank has
spent approximately $85,000 in direct and indirect costs on Year 2000 compliance
issues. Management expects to spend an additional $30,000 in 1999 to complete
its remediation efforts. The costs to complete the Bank's Year 2000 modification
and testing processes are management's best estimates. Actual events are
dependent on the continued availability of certain resources, third party
modification plans and other factors.(1)

LOANS:

The Bank offers a broad range of commercial and consumer lending products.
Credit is extended principally to small and medium sized businesses, and
residents in the local area. Outstanding loans totaled $182.0 million at March
31, 1999, representing a $3.3 million increase when compared to loans of $178.7
million as of December 31, 1998.

Commitments, principally real estate construction notes and commercial lines of
credit, have grown to $29.0 million at March 31, 1999, a 33% increase when
compared to commitments outstanding as of the end of the previous year.

Reflective of the Bank's lending criteria, as well as trends within the local
economy, 71% of the Bank's loan portfolio is classified as real estate mortgage
loans. Of the $127 million in real estate mortgage loans outstanding as of March
31, 1999, approximately $83 million were made to commercial customers where the
collateral for the loans includes the real estate occupied by the customers'
businesses. An additional $27 million represented loans secured by multi family
(5 or more) residential property and the remaining $17 



                                       14

million was secured by family residential property. This is relatively unchanged
from previous reporting periods.

</TABLE>


LOAN LOSS RESERVE:

The reserve for loan losses represents management's estimate of the Bank's
exposure to credit loss when evaluating the asset quality of the loan portfolio.
The reserve is based primarily on management's evaluation of the overall risk
characteristics of the Bank's loan portfolio, which is influenced by non
performing loans, value of collateral, general and local economic conditions and
historical loan loss experience. Management seeks to mitigate credit losses by
maintaining strong underwriting standards and closely monitoring the financial
condition of the borrower. As of March 31, 1999, the Bank's allowance for loan
losses was $3,546,000 or 1.95% of total loans, and is believed to be adequate to
absorb potential credit losses that may arise in the normal course of
business(1).

As of March 31, 1999, total non performing assets as a percentage of total
assets increased slightly to .28%, to total $840,000. The increase is
attributable to the credit issues of one borrower. The note is well
collateralized, and management expects to resolve the delinquency without moving
into foreclosure(1).

Recoveries exceeded charge offs in the 1st quarter of 1999, for net recoveries
of $7,000. Due to the Bank's substantial loan loss reserve and the strength of
the Bank's loan portfolio, the Bank has not recorded a loan loss provision in
1999.

INVESTMENT PORTFOLIO:

Investment securities are purchased for managing liquidity and generating after
tax profits consistent with the risk guidelines established by management and
the Board of Directors. As of March 31, 1999, the Bank's portfolio of investment
securities totaled $76.6 million, virtually unchanged when compared to the
balance of the portfolio at December 31, 1998 of $76.5 million.

VRB follows financial accounting principles that require the identification of
investment securities as held-to-maturity ("HTM") or available-for-sale ("AFS").
Securities designated as HTM are those that VRB has the intent and ability to
hold until they mature or are called, rather than those that management may sell
if liquidity requirements dictate.

As of March 31, 1999, the Bank's investment portfolio that is currently AFS
totaled $56.7 million, or approximately 74% of the total portfolio. Due to
recent improvements in average yields for similar securities now available in
the bond market, the market value the AFS portfolio has dropped by approximately
$363,000, net of tax. This represents a one percent decline in the aggregate
market value of the Bank's available for sale investments. If long term rates
continue to increase, the value of the Bank's investment holdings will most
likely decline. This could hinder the Bank's ability to quickly liquidate
securities without incurring a loss on the sale. Because future rate
fluctuations are subject to great uncertainty, management continues to monitor
the market value of the portfolio in relation to current liquidity needs on a
regular basis.(1)

DEPOSITS:

Deposits are the Bank's major source of funds available for lending and other
investment opportunities. Deposit inflows and outflows, are influenced by
general interest rates and economic conditions. Substantially all of the Bank's
depositors are residents of southern Oregon.

Total deposits declined $7.2 million, or 3% when comparing March 31, 1999 to the
end of 1998. Fluctuations in noninterest bearing deposits are common and despite
the decline in balances outstanding on March 31, 1999, the Bank continues to
experience conservative account growth. Time certificates of deposit continue
their decline as seen in 1998. The decline is linked to those accounts acquired
from CBC, as funds mature and leave seeking higher returns. This trend will most
likely continue until management determines that growth in time certificates of
deposit is financially beneficial, and alters its pricing strategy
accordingly.(1) The decline in time certificates of deposits has resulted in a
lower average cost of funds. For example, when comparing the 4th quarter of 1998
to the 1st quarter of 1999, the Bank's average cost of funds declined from 2.51%
to 2.40%

PART I - FINANCIAL INFORMATION
ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, interest rate and credit risks are the most
significant market risks that could have an adverse impact on the Bank's
financial condition and results of operation. Other types of market risk, such
as foreign currency exchange rate risk and commodity price risk are not
applicable to Bank operations at this time.

INTEREST RATE RISK

Interest rate risk is managed through the monitoring of the Bank's "gap"
position, and the sensitivity of the bank's net interest margins and capital
position to changing interest rate environments. The Bank's gap is the
difference between re-pricing assets and re-pricing liabilities over specific
time periods. By managing the re-pricing characteristics of the Bank's assets
and liabilities, the Bank can minimize the potential adverse impact from
changing interest rates.

Periodically, the Bank will "rate shock" the balance sheet by simulating a 100
and 200 basis point change in interest rates. Rate shock is an instantaneous
adjustment in market rates on a balance sheet level to determine the effect such
changes would have on the Company's income levels and capital position for the
succeeding twelve months.

As of March 31, 1999, management's analysis indicated that the Bank's overall
interest rate risk was within acceptable guidelines and that there are no
material changes in the Bank's exposure to mismatched re-pricing positions from
that reported as of December 31, 1998.

CREDIT RISK

Credit risk is principally controlled by prudent loan underwriting standards and
adequate allowances for potential loan loss (See discussion under Item 2 -
Management discussion and analysis, Loans and Loan Loss Reserve).
