                            AMERICAN RIVER BANKSHARES
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 2004

1. UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

In the opinion of management, the unaudited consolidated financial statements
contain all adjustments (consisting of only normal recurring adjustments)
necessary to present fairly the consolidated financial position of American
River Bankshares (the "Company") at September 30, 2004 and December 31, 2003,
and the results of its operations for the three and nine month periods ended
September 30, 2004 and 2003 and cash flows for the nine month periods ended
September 30, 2004 and 2003 in conformity with accounting principles generally
accepted in the United States of America.

Certain disclosures normally presented in the notes to the financial statements
prepared in accordance with generally accepted accounting principles have been
omitted. These interim consolidated financial statements should be read in
conjunction with the consolidated financial statements and notes thereto
included in the Company's 2003 Annual Report to Shareholders. The results of
operations for the three and nine month periods ended September 30, 2004 may not
necessarily be indicative of the operating results for the full year.

In preparing such financial statements, management is required to make estimates
and assumptions that affect the reported amounts of assets and liabilities as of
the date of the balance sheet and revenues and expenses for the period. Actual
results could differ significantly from those estimates. Material estimates that
are particularly susceptible to significant changes in the near term relate to
the determination of the allowance for loan and lease losses, the provision for
taxes and the estimated fair value of investment securities.

2. STOCK-BASED COMPENSATION

At September 30, 2004, the Company had two stock-based compensation plans. The
Company accounts for these plans under the recognition and measurement
principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and
related Interpretations. Under APB Opinion No. 25, stock-based compensation cost
is only reflected in net income when options granted under these plans have an
exercise price less than the market value of the underlying common stock on the
date of grant or if the original terms are later modified.

Pro forma adjustments to the Company's consolidated net earnings and earnings
per share are disclosed during the years in which the options become vested. The
following table illustrates the effect on net income and earnings per share if
the Company had applied the fair value recognition provisions of FASB Statement
No. 123, Accounting for Stock-Based Compensation, to stock-based compensation.

3. COMMITMENTS AND CONTINGENCIES

In the normal course of business there are outstanding various commitments to
extend credit which are not reflected in the financial statements, including
loan commitments of approximately $78,138,000 and letters of credit of
$1,997,000 at September 30, 2004. However, all such commitments will not
necessarily culminate in actual extensions of credit by the Company during 2004.

Approximately $18,432,000 of the loan commitments outstanding at September 30,
2004 are for real estate construction loans and are expected to fund within the
next twelve months. The remaining commitments primarily relate to revolving
lines of credit or other commercial loans, and many of these are expected to
expire without being fully drawn upon. Therefore, the total commitments do not
necessarily represent future cash requirements. Each potential borrower and the
necessary collateral are evaluated on an individual basis. Collateral varies,
but may include real property, bank deposits, debt or equity securities or
business assets.

Stand-by letters of credit are commitments written to guarantee the performance
of a customer to a third party. These guarantees are issued primarily relating
to purchases of inventory by commercial customers and are typically short-term
in nature. Credit risk is similar to that involved in extending loan commitments
to customers and accordingly, evaluation and collateral requirements similar to
those for loan commitments are used. Virtually all such commitments are
collateralized.

4. EARNINGS PER SHARE COMPUTATION

Basic earnings per share is computed by dividing net income by the weighted
average common shares outstanding for the period (4,243,910 and 4,198,917 shares
for the three and nine month periods ended September 30, 2004, and 3,996,862 and
3,976,440 shares for the three and nine month periods ended September 30, 2003).
Diluted earnings per share reflect the potential dilution that could occur if

                                       8


outstanding stock options were exercised. Diluted earnings per share is computed
by dividing net income by the weighted average common shares outstanding for the
period plus the dilutive effect of options (175,073 and 202,365 shares for the
three and nine month periods ended September 30, 2004 and 340,906 and 328,555
shares for the three and nine month periods ended September 30, 2003). Earnings
per share is retroactively adjusted for stock dividends and stock splits for all
periods presented.

5. COMPREHENSIVE INCOME

Comprehensive income is reported in addition to net income for all periods
presented. Comprehensive income is made up of net income plus other
comprehensive income (loss). Other comprehensive income (loss), net of taxes,
was comprised of the unrealized gains (losses) on available-for-sale investment
securities of $446,000 and $(226,000), respectively, for the three and nine
month periods ended September 30, 2004 and $(253,000) and $(280,000),
respectively, for the three and nine month periods ended September 30, 2003.
Comprehensive income was $1,785,000 and $3,700,000, respectively, for the three
and nine month periods ended September 30, 2004 and $1,007,000 and $3,332,000,
respectively, for the three and nine month periods ended September 30, 2003.

6. SHORT-TERM BORROWING ARRANGEMENTS

The Company has a total of $48,000,000 in unsecured short-term borrowing
arrangements with four of its correspondent banks. There were no advances
outstanding with these correspondent banks at September 30, 2004. An advance
totaling $9,600,000 was outstanding from one of its correspondent banks at
December 31, 2003, bearing an interest rate of 1.44% and maturing on January 1,
2004.

In addition, the Company has a line of credit available with the Federal Home
Loan Bank (the "FHLB") which is secured by pledged mortgage loans and investment
securities. Borrowings may include overnight advances as well as loans with
terms of up to thirty years. Advances totaling $36,300,000 were outstanding from
the FHLB at September 30, 2004, bearing interest rates ranging from 1.16% to
2.66% and maturing between October 4, 2004 and May 5, 2006. Advances totaling
$25,000,000 were outstanding from the FHLB at December 31, 2003, bearing
interest rates ranging from 1.03% to 1.45% and maturing between January 2, 2004
and November 1, 2004.

Management periodically evaluates each investment security relying primarily on
industry analyst reports, observation of market conditions and interest rate
fluctuations. Management believes it will be able to collect all amounts due
according to the contractual terms of the underlying investment securities and
that the noted decline in fair value is due only to interest rate fluctuations.

8. PROPOSED MERGER TRANSACTION WITH BANK OF AMADOR

On July 9, 2004, the Company and Jackson, California-based Bank of Amador,
announced jointly the signing of an Agreement and Plan of Reorganization and
Merger dated July 8, 2004, whereby the Company will acquire Bank of Amador
through the merger of Bank of Amador with and into American River Bank. Based
upon American River Bankshares' closing price of $20.40 as of July 8, 2004, the
transaction is currently valued at approximately $19.50 per share, or $30.5
million for Bank of Amador shareholders. Upon completion of the transaction,
Bank of Amador will operate as a division of American River Bank under the name
"Bank of Amador, a division of American River Bank." The Board of Directors of
both companies unanimously approved the definitive agreement. The transaction is
subject to regulatory approvals and the approval by the shareholders of American
River Bankshares and Bank of Amador. On September 17, 2004, the Company filed a
registration statement of Form S-4 with the SEC that included a description of
the proposed merger and the Agreement and Plan of Reorganization and Merger and
exhibits thereto. The Form S-4 can be accessed free of charge through the
Company's website address www.amrb.com by clicking on the SEC Filings link
located at that address. The transaction is expected to close in the fourth
quarter of 2004.

Critical Accounting Policies

General

         The Company's financial statements are prepared in accordance with
accounting principles generally accepted in the United States of America
("GAAP"). The financial information contained within our statements is, to a
significant extent, financial information that is based on measures of the
financial effects of transactions and events that have already occurred. We use
historical loss data, peer group experience and the economic environment as
factors, among others, in determining the inherent loss that may be present in
our loan and lease portfolio. Actual losses could differ significantly from the
historical factors that we use. Other estimates that we use are related to the
expected useful lives of our depreciable assets. In addition GAAP itself may
change from one previously acceptable method to another method. Although the
economics of our transactions would be the same, the timing of events that would
impact our transactions could change.

Allowance for Loan and Lease Losses

         The allowance for loan and lease losses is an estimate of the credit
loss risk in our loan and lease portfolio. The allowance is based on two basic
principles of accounting: (1) Statement of Financial Accountings Standards
("SFAS") No. 5 "Accounting for Contingencies," which requires that losses be
accrued when they are probable of occurring and estimable; and (2) SFAS No. 114,
"Accounting by Creditors for Impairment of a Loan," which requires that losses
be accrued based on the differences between the value of collateral, present
value of future cash flows or values that are observable in the secondary market
and the loan balance.

                                       11


         The allowance for loan and lease losses is determined based upon
estimates that can and do change when the actual risk or loss events occur. The
analysis of the allowance uses an historical loss view as an indicator of future
losses and as a result could differ from the loss incurred in the future.
However, since our analysis of risk and loss potential is updated regularly, the
errors that might otherwise occur are mitigated. The use of factors and ranges
is inherently subjective and our actual losses could be greater or less than the
estimates. The Company's goal is to maintain an allowance for loan and lease
losses that is between the lower and upper ranges as described above. If the
allowance for loan and lease losses falls below the lower range of adequate
reserves (by reason of loan and lease growth, actual losses, the effect of
changes in risk ratings, or some combination of these factors), the Company has
a strategy for supplementing the allowance for loan and lease losses, over the
short term, so that it would again fall within the lower and upper acceptable
ranges. For further information regarding our allowance for loan and lease
losses, see "Allowance for Loan and Lease Losses Activity" discussion later in
this Item.

Stock Based Awards

         The Company accounts for its stock based awards using the intrinsic
value method in accordance with Accounting Principles Board ("APB") Opinion No.
25 and related interpretations. Since the Company's stock option plan provides
for the issuance of options at a price of no less than the fair market value at
the date of the grant, no compensation expense is recognized in the financial
statements unless the options are modified after the grant date.


General Development of Business

         The Company is a bank holding company registered under the Bank Holding
Company Act of 1956, as amended. The Company was incorporated under the laws of

inactive since its formation in 1994.

         The Company conducted no significant activities other than holding the
shares of its subsidiaries. However, it is authorized, with the prior approval
of the Board of Governors of the Federal Reserve System, the Company's principal
regulator, to engage in a variety of activities which are deemed closely related

Net Interest Income and Net Interest Margin

         Net interest income represents the excess of interest and fees earned
on interest earning assets (loans and leases, securities, Federal funds sold and
investments in time deposits) over the interest paid on deposits and borrowed
funds. Net interest margin is net interest income expressed as a percentage of
average earning assets. The Company's net interest margin was 4.78% for the
three months ended September 30, 2004, 5.11% for the three months ended
September 30, 2003, 4.85% for the nine months ended September 30, 2004 and 5.21%
for the nine months ended September 30, 2003.

         The fully taxable equivalent interest income component for the third
quarter of 2004 increased $721,000 (14.4%) to $5,716,000 compared to $4,995,000
for the three months ended September 30, 2003. Total fully taxable equivalent
interest income for the nine months ended September 30, 2004 increased
$1,323,000 (8.9%) to $16,271,000 compared to $14,948,000 for the nine months
ended September 30, 2003. The increase in the fully taxable equivalent interest
income for the third quarter of 2004 compared to the same period in 2003 is
broken down by rate (down $133,000) and volume (up $854,000). The rate decrease
can be attributed to decreases implemented by the Company during 2001 and 2002
in response to Federal Reserve Board (the "FRB") decreases in the Federal funds
and Discount rates. Recent increases by the FRB have resulted in three 25 basis
point increases since June 2004; however, these recent increases have had only a
minor effect. The overall lower interest rate environment over the past three
years has resulted in a 36 basis point drop in the yield on average earning
assets from 5.92% for the third quarter of 2003 to 5.56% for the third quarter
of 2004. The volume increase was the result of a 22.3% increase in average
earning assets. Average loan balances were up $20,869,000 (8.4%) in 2004 over
the balances in 2003, while average investment securities balances were up
$57,986,000 (82.8%). The increase in average loans is the result of a
concentrated focus on business lending, the demand for commercial real estate
and the effects of a favorable local market. The increase in investment
securities is primarily due to the Company investing its excess funds in
investment securities. The excess funds were created by an increase in deposit
balances and other borrowings. The breakdown of the fully taxable equivalent
interest income for the nine months ended September 30, 2004 over the same
period in 2003 resulted from increases in volume (up $2,324,000) and decreases
in rate (down $1,001,000). Average earning assets increased $60,416,000 (18.5%)
during the first nine months of 2004 as compared to the same period in 2003.
Average loan balances increased $24,348,000 (9.9%) during that same period and
average investment securities balances increased $37,021,000 (51.3%).

         Interest expense was $116,000 (16.9%) higher in the third quarter of
2004 versus the prior year period. The average balances on interest bearing
liabilities were $54,131,000 (23.3%) higher in the third quarter of 2004 versus
the same quarter in 2003. The higher balances accounted for a $129,000 increase
in interest expense; however, this increase was somewhat offset by a slight drop
in rates (down $13,000). The decrease in rates paid on interest bearing
liabilities was a result of the lower interest rate environment over the past
three years, although these rates have been increasing over the past few months,
the rates paid on interest bearing liabilities decreased 5 basis points on a
quarter-over-quarter basis. Interest expense was $9,000 (0.4%) higher in the
nine month period ended September 30, 2004 versus the prior year period. The
average balances on interest bearing liabilities were $39,330,000 (16.9%) higher
in the nine-month period ended September 30, 2004 versus the same period in
2003. The higher balances accounted for a $252,000 increase in interest expense.
The increase due to higher balances was offset by lower rates paid on interest
bearing liabilities. The average rate paid on interest bearing liabilities
decreased 18 basis points on a year-over-year basis and accounted for a decrease
in interest expense of $243,000.

Three, Analysis of Volume and Rate Changes on Net Interest Income and Expenses,
are provided to enable the reader to understand the components and trends of the
Company's interest income and expenses. Table Two provides an analysis of net
interest margin on earning assets setting forth average assets, liabilities and
shareholders' equity; interest income earned and interest expense paid and
average rates earned and paid; and the net interest margin on earning assets.

     certain securities that is exempt from federal income taxes. The effective
     federal statutory tax rate was 34% for the periods presented.
(3)  Net interest margin is computed by dividing net interest income by total
     average earning assets.
(4)  Average yield is calculated based on actual days in period (182) and
     annualized to actual days in year (366 for 2004 and 365 for 2003).

Provision for Loan and Lease Losses

         The Company provided $266,000 for loan and lease losses for the third
quarter of 2004 as compared to $252,000 for the third quarter of 2003. Net loan
and lease charge-offs for the three months ended September 30, 2004 were $3,000
or .00% (on an annualized basis) of average loans and leases as compared to
$133,000 or .21% (on an annualized basis) of average loans and leases for the
three months ended September 30, 2003. For the first nine months of 2004, the
Company made provisions for loan and lease losses of $695,000 and net loan and
lease charge-offs were $148,000 or .07% (on an annualized basis) of average
loans and leases outstanding. This compares to provisions for loan and lease
losses of $664,000 and net loan and lease charge-offs of $244,000 for the first
nine months of 2003 or .13% (on an annualized basis) of average loans and leases
outstanding.

- ----------------------------------------------------------------------------------------
           Total noninterest income    $      441   $      645   $    1,892   $    1,736
- ----------------------------------------------------------------------------------------


         Noninterest income was down $204,000 (31.6%) to $441,000 for the three
months ended September 30, 2004 as compared to $645,000 for the three months
ended September 30, 2003. The primary traditional sources of noninterest income
for the Company are service charges on deposit accounts, accounts receivable
servicing fees, merchant credit card fees and income from residential lending.
The decrease in noninterest income for the quarter can be attributed to
decreases in fees from lease brokerage services (down $118,000 or 99.2%) and a
decrease in residential lending fee income (down $80,000 or 74.1%). The decrease
in lease brokerage services resulted from the majority of the third quarter 2004
Company originated leases being recorded on the books of the Company as opposed
to receiving fee income for brokering the leases to outside funding sources. In
addition, overall lease volume has decreased (from $1,965,000 in the third
quarter of 2003 to $537,000 in the third quarter of 2004) as a result of the
change from a nationwide lessor to a lessor that does business in California
counties that are proximate to our branch locations. The residential lending
division experienced a decrease in loan volume as a result of a slight increase
in mortgage rates, which caused the number of refinances to decrease.

         For the nine months ended September 30, 2004, noninterest income was up
$156,000 (9.0%) to $1,892,000. Much of this increase ($553,000) represents the
tax-free net proceeds from a life insurance policy the Company received in June
of 2004 as a result of the death of a former executive officer. Without the life
insurance proceeds, noninterest income would have shown a decrease of $397,000.
The decrease in noninterest income for the nine-month period can be attributed
to decreases in fees from lease brokerage services (down $315,000 or 96.9%) and
a decrease in residential lending fee income (down $176,000 or 61.8%).

                                       18


Noninterest Expense

         Noninterest expenses increased $227,000 (8.8%) to a total of $2,814,000
in the third quarter of 2004 versus the third quarter of 2003. The majority of
the increase relates to the cost associated with the new banking office in
Downtown Sacramento ($203,000) located at 520 Capitol Mall, Suite 100,
Sacramento, CA 95814. Salary and employee benefits, which include commissions,
increased $4,000 (0.3%) from $1,522,000 during the third quarter of 2003 to
$1,526,000 during the third quarter of 2004. Comparing the third quarter of 2004
with that of 2003, occupancy expense increased $41,000 (20.0%) and furniture and
equipment increased $19,000 (11.2%). The new location contributed $38,000 to the
increased occupancy expense and $15,000 to the increased furniture and equipment
expense. Other expense increased $163,000 (23.6%) to a total of $853,000 in the
third quarter of 2004 versus the third quarter of 2003. The increase in other
expense can be attributed to Professional fees (up $45,000 or 46.9%) and
directors expenses (up $47,000 or 50.5%). Professional fees, which includes
accounting, legal and other professional services, was up primarily due to
retainer fees paid to a deposit gathering relationship established earlier in
2004 ($66,000). The increase in director fees relates to higher amounts accrued
under the Gross-Up Plan (the "Plan"). The Plan compensates for the tax effects
of the exercise of nonstatutory stock options. The Plan named certain
non-employee Directors as participants and applies only to those options granted
on August 25, 1995. The Plan encourages participating optionees to retain shares
acquired through the exercise of nonstatutory stock options by the Company
paying to the participating optionee an amount equal to the taxable income
resulting from an exercise of a nonstatutory stock option multiplied by the
Company's effective tax rate, subject to the optionee's agreement to hold the
shares acquired for a minimum of one (1) year. The efficiency ratios (fully
taxable equivalent) for the 2004 and 2003-third quarters were 52.6% and 52.2%,
respectively.

         There were no expenses in the third quarter of 2004 associated with the
proposed merger between the Company, American River Bank, and Bank of Amador
because the Company anticipates accounting for the transaction using the
purchase method of accounting which requires that merger related costs be
capitalized as goodwill.

         Noninterest expense for the nine-month period ended September 30, 2004
was $9,026,000 versus $7,702,000 for the same period in 2003 for an increase of
$1,324,000 (17.2%). Salaries and benefits increased $32,000 (0.7%) in 2004 as
compared to 2003. Full time equivalent employees ("FTE's") decreased to 96 at
September 2004 from 99 at September 30, 2003. Occupancy increased $86,000
(14.1%) and furniture and equipment increased $72,000 (14.9%). The increase in
occupancy and furniture and equipment relates to the opening of the new location
in Downtown Sacramento--the office contributed $76,000 to the increased
occupancy expense and $37,000 to the increased furniture and equipment expense.
The remainder of the furniture and equipment increase is related to the
depreciation of technology related equipment purchased by the Company over the
past twelve months. Other expense increased $1,134,000 (57.9%). A substantial
portion of this increase can be attributed to the Company's decision to create a
charitable foundation ($503,000) known as the American River Bankshares
Foundation and the benefit payments related to the death of a former Company
executive ($82,000), Professional fees (up $120,000) and director expenses (up
$147,000). The overhead efficiency (fully taxable equivalent) ratio for the
first nine months of 2004 was 56.6% as compared to 53.2% in the same period of
2003.

Provision for Income Taxes

         The effective tax rate for the third quarter and first nine months of
2004 was 40.0% and 35.2%, respectively, versus 39.2% and 39.7%, respectively,
for the same two periods of 2003. The decrease in the effective tax rate on a
year to date basis is related to the tax-free nature of the above-referenced
life insurance proceeds.

Balance Sheet Analysis

         The Company's total assets were $456,677,000 at September 30, 2004 as
compared to $397,393,000 at December 31, 2003, representing an increase of
14.9%. The average balances of total assets for the nine months ended September
30, 2004 was $421,836,000 which represents an increase of $66,494,000 or 18.7%

                                       19


over the $355,342,000 during the nine month period ended September 30, 2003.
Total average assets for the third quarter of 2004 were $446,772,000 compared to
$365,613,000 during the third quarter of 2003 for an increase of 22.2%.

Loans and Leases

         The Company concentrates its lending activities in the following
principal areas: 1) commercial; 2) commercial real estate; 3) multi-family real
estate; 4) real estate construction (both commercial and residential); 5)
residential real estate; 6) lease financing receivable; 7) agriculture; and 8)
consumer loans. At September 30, 2004, these categories accounted for
approximately 21%, 50%, 1%, 18%, 1%, 4%, 3% and 2%, respectively, of the
Company's loan portfolio. This mix was relatively unchanged compared to 22%,
53%, 2%, 14%, 1%, 3%, 3% and 2% at December 31, 2003. Continuing economic
activity in the Company's market area, new borrowers developed through the
Company's marketing efforts and additional credit extensions to existing
borrowers, offset by normal loan paydowns and payoffs, resulted in net increases
in balances for commercial ($166,000 or 0.3%), commercial real estate
($4,616,000 or 3.2%), real estate construction ($3,251,000 or 8.7%), lease
financing receivable ($888,000 or 9.6%), agriculture ($318,000 or 4.0%) and
consumer ($79,000 or 1.3%). The Company experienced a decrease in multi-family
real estate ($2,666,000 or 50.3%) and residential real estate ($615,000 or
40.8%) as a result of normal paydowns. Table Five below summarizes the
composition of the loan portfolio as of September 30, 2004 and December 31,
2003.

===============================================================================

         A significant portion of the Company's loans and leases are direct
loans and leases made to individuals and local businesses. The Company relies
substantially on local promotional activity and personal contacts by bank
officers, directors and employees to compete with other financial institutions.
The Company makes loans and leases to borrowers whose applications include a
sound purpose and a viable primary repayment source, generally supported by a
secondary source of repayment. Commercial loans consist of credit lines for
operating needs, loans for equipment purchases, working capital, and various
other business loan products. Consumer loans include a range of traditional
consumer loan products such as personal lines of credit and loans to finance
purchases of autos, boats, recreational vehicles, mobile homes and various other
consumer items. Construction loans are generally comprised of commitments to
customers within the Company's service area for construction of commercial
properties, multi-family properties and custom and production-type single-family
residences. Other real estate loans consist primarily of loans secured by first
trust deeds on commercial and residential properties typically with maturities
from 3 to 10 years and original loan to value ratios generally from 65% to 75%.
Agriculture loans consist primarily of vineyard loans and development loans to
plant vineyards. In general, except in the case of loans under SBA programs or
Farm Services Agency guarantees, the Company does not make long-term mortgage

                                       20


loans; however, American River Bank has a residential lending division to assist
customers in securing most forms of longer term single-family mortgage
financing. American River Bank acts as a broker between American River Bank's
customers and the loan wholesalers. American River Bank receives an origination
fee for loans closed.

Risk Elements

         The Company assesses and manages credit risk on an ongoing basis
through a total credit culture that emphasizes excellent credit quality,
extensive internal monitoring and established formal lending policies.
Additionally, the Company contracts with an outside loan review consultant to
periodically review the existing loan and lease portfolio. Management believes
its ability to identify and assess risk and return characteristics of the
Company's loan and lease portfolio is critical for profitability and growth.
Management strives to continue its emphasis on credit quality in the loan and
lease approval process, active credit administration and regular monitoring.
With this in mind, management has designed and implemented a comprehensive loan
and lease review and grading system that functions to assess the credit risk
inherent in the loan and lease portfolio.

         Ultimately, underlying trends in economic and business cycles may
influence credit quality. American River Bank's business is concentrated in the
Sacramento Metropolitan Statistical Area, which is a diversified economy, but
with a large State of California government presence and employment base, and in
Sonoma County through North Coast Bank, a division of American River Bank. The
Company's business in Sonoma County is focused mainly on commercial and real
estate enterprises within the three communities in which it has offices (Santa
Rosa, Windsor, and Healdsburg). The economy of Sonoma County is diversified with
professional services, manufacturing, agriculture and real estate investment and
construction.

         The Company has significant extensions of credit and commitments to
extend credit that are secured by real estate. The ultimate repayment of these
loans is generally dependent on personal or business cash flows or the sale or
refinancing of the real estate. The Company monitors the effects of current and
expected market conditions and other factors on the collectability of real
estate loans. The more significant factors management considers involve the
following: lease rate and terms, absorption and sale rates; real estate values
and rates of return; operating expenses; inflation; and sufficiency of repayment
sources independent of the real estate including, in some instances, personal
guarantees.

         In extending credit and commitments to borrowers, the Company generally
requires collateral and/or guarantees as security. The repayment of such loans
is expected to come from cash flow or from proceeds from the sale of selected
assets of the borrowers. The Company's requirement for collateral and/or
guarantees is determined on a case-by-case basis in connection with management's
evaluation of the creditworthiness of the borrower. Collateral held varies but
may include accounts receivable, inventory, property, plant and equipment,
income-producing properties, residences and other real property. The Company
secures its collateral by perfecting its security interest in business assets,
obtaining deeds of trust, or outright possession among other means.

         In management's judgment, a concentration exists in real estate loans
which represented approximately 70.0% of the Company's loan and lease portfolio
at September 30, 2004. Although management believes this concentration to have
no more than the normal risk of collectability, a substantial decline in the
economy in general, or a decline in real estate values in the Company's primary
market areas in particular, could have an adverse impact on the collectability
of these loans and require an increase in the provision for loan and lease
losses which could adversely affect the Company's future prospects, results of
operations, profitability and stock price. Management believes that its lending
policies and underwriting standards will tend to minimize losses in an economic
downturn, however, there is no assurance that losses will not occur under such
circumstances. The Company's loan policies and underwriting standards include,
but are not limited to, the following: (1) maintaining a thorough understanding
of the Company's service area and originating a significant majority of its
loans within that area, (2) maintaining a thorough understanding of borrowers'
knowledge, capacity, and market position in their field of expertise, (3) basing
real estate loan approvals not only on market demand for the project, but also
on the borrowers' capacity to support the project financially in the event it
does not perform to expectations (whether sale or income performance), and (4)

                                       21


maintaining conforming and prudent loan-to-value and loan-to-cost ratios based
on independent outside appraisals and ongoing inspection and analysis by the
Company's lending officers.

Nonaccrual, Past Due and Restructured Loans & Leases

         Management generally places loans on nonaccrual status when they become
90 days past due, unless the loan is well secured and in the process of
collection. Loans are charged off when, in the opinion of management, collection
appears unlikely. At September 30, 2004, non-performing loans and leases were
0.04% of total loans and leases. The recorded investments in loans that were
considered to be impaired totaled $103,000 at September 30, 2004 and $181,000 at
December 31, 2003.

         Table Six below sets forth nonaccrual loans and loans past due 90 days
or more as of September 30, 2004 and December 31, 2003.

===============================================================================

         There were no loan concentrations in excess of 10% of total loans not
otherwise disclosed as a category of loans as of September 30, 2004 or December
31, 2003. There were zero and $5,000 in restructured loans as of September 30,
2004 and December 31, 2003, respectively. Management is not aware of any
potential problem loans, which were accruing interest at September 30, 2004,
where serious doubt exists as to the ability of the borrower to comply with the
present repayment terms.

Allowance for Loan and Lease Losses Activity

         The Company maintains an allowance for loan and lease losses ("ALLL")
to cover potential losses inherent in the loan and lease portfolio, which is
based upon management's estimated range of those losses. The ALLL is established
through a provision for loan and lease losses and is increased by provisions
charged against current earnings and recoveries and reduced by charge-offs.
Actual losses for loans and leases can vary significantly from this estimate.
The methodology and assumptions used to calculate the allowance are periodically
reviewed as to their appropriateness given the most recent losses realized and
other factors that influence the estimation process. The model assumptions and
resulting allowance level are adjusted accordingly as these factors change. The
ALLL totaled $4,496,000 or 1.65% of total loans and leases at September 30, 2004
and $3,949,000 or 1.48% at December 31, 2003. Net charge-offs to average loans
and leases were 0.00% (on an annualized basis) for the third quarter of 2004 and
..07% (on an annualized basis) for the nine-month period ended September 30,
2004. Net charge-offs to average loans and leases were 0.21% (on an annualized
basis) for the third quarter of 2003 and .13% (on an annualized basis) for the
nine-month period ended September 30, 2003.

         The adequacy of the ALLL and the level of the related provision for
loan and lease losses is determined based on management's judgment after
consideration of numerous factors including but not limited to: (i) local and
regional economic conditions, (ii) borrowers' financial condition, (iii) loan
impairment and the related level of expected charge-offs, (iv) evaluation of
industry trends, (v) industry and other concentrations, (vi) loans which are

                                       22


contractually current as to payment terms but demonstrate a higher degree of
risk as identified by management, (vii) continuing evaluations of the performing
loan portfolio, (viii) ongoing review and evaluation of problem loans identified
as having loss potential, (ix) quarterly review by the Board of Directors, and
(x) assessments by banking regulators and other third parties. Management and
the Board of Directors evaluate the ALLL and determine its desired level
considering objective and subjective measures, such as knowledge of the
borrowers' business, valuation of collateral, the determination of impaired
loans or leases and exposure to potential losses.

         Table Seven below summarizes, for the periods indicated, the activity
in the allowance for loan and lease losses.

         The Company establishes general reserves in accordance with Statement
of Accounting Standards ("SFAS") No. 5., Accounting for Contingencies, and
specific reserves in accordance with SFAS No. 114, Accounting by Creditors for
Impairment of a Loan. The ALLL is maintained by categories of the loan portfolio
based on loan type and loan rating; however, the entire allowance is available
to cover actual loan and lease losses. While management uses available
information to recognize possible losses on loans and leases, future additions
to the allowance may be necessary, based on changes in economic conditions and
other matters. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Company's ALLL. Such agencies
may require the Company to provide additions to the allowance based on their
judgment of information available to them at the time of their examination.

                                       23


         The adequacy of the ALLL is determined based on three components. First
is the dollar weighted risk rating of the loan portfolio, including all
outstanding loans and leases. Every extension of credit has been assigned a loan
type and risk rating based upon a comprehensive definition intended to measure
the inherent risk of lending money. Each type and rating has an assigned risk
factor expressed as a reserve percentage. Second, established specific reserves
consistent with SFAS No. 114 "Accounting by Creditors for Impairment of a Loan"
are assigned to individually impaired loans. These are estimated potential
losses associated with specific borrowers based upon estimated cash flows or
collateral value and events affecting the risk rating. Third, the Company
maintains a reserve for qualitative factors that may affect the portfolio as a
whole, such as those factors described above, including a reserve for model
imprecision consistent with SFAS No. 5 "Accounting for Contingencies."

Other Real Estate

         At September 30, 2004 and December 31, 2003, the Company did not have

$322,507,000. Noninterest-bearing deposits increased $24,661,000 (24.1%) while
interest-bearing deposits increased $28,068,000 (12.7%). Interest checking,
money market and savings accounts increased $33,744,000 (22.7%) while time
deposits decreased $5,675,000 (7.9%).

         The Company has also been issued a total of $500,000 in letters of
credit by the FHLB which have been pledged to secure Local Agency Deposits. The
letters of credit act as a guarantee of payment to certain third parties in
accordance with specified terms and conditions. The letters of credit were not
drawn upon in 2004 or 2003 and management does not expect to draw upon these
lines in the future.

Capital Resources

         The current and projected capital position of the Company and the
impact of capital plans and long-term strategies is reviewed regularly by
management. The Company's capital position represents the level of capital
available to support continuing operations and expansion.

         The Company and American River Bank are subject to certain regulations
issued by the Board of Governors of the Federal Reserve System and the Federal
Deposit Insurance Corporation, which require maintenance of certain levels of
capital. Failure to meet these minimum capital requirements can initiate certain
mandatory, and possibly additional discretionary, actions by regulators that, if
undertaken, could have a direct material effect on the Company's consolidated
financial statements. Under capital adequacy guidelines and the regulatory
framework for prompt corrective action, American River Bank must meet specific
capital guidelines that involve quantitative measures of their assets,
liabilities and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Company's and American River Bank's capital amounts
and classification are also subject to qualitative judgments by the regulators
about components, risk weightings and other factors. At September 30, 2004,
shareholders' equity was $39,101,000, representing an increase of $3,644,000
(10.3%) from $35,457,000 at December 31, 2003. The ratio of total risk-based
capital to risk adjusted assets was 13.5% at September 30, 2004 compared to
12.9% at December 31, 2003. Tier 1 risk-based capital to risk-adjusted assets
was 12.3% at September 30, 2004 and 11.6% at December 31, 2003.

         Table Eight below lists the Company's actual capital ratios at
September 30, 2004 and December 31, 2003 as well as the minimum capital ratios
for capital adequacy.

         On September 20, 2001, the Company announced a plan to repurchase, as
conditions warrant, up to 5% annually of the Company's common stock. During the
first nine months of 2004, the Company repurchased 9,300 shares; during 2003,
the Company repurchased 1,500 shares; during 2002, the Company repurchased
65,627 shares and in 2001, the Company repurchased 33,705 shares under the
repurchase plan. (See Part II, Item 2, for additional disclosure).

         Capital ratios are reviewed on a regular basis to ensure that capital
exceeds the prescribed regulatory minimums and is adequate to meet future needs.
Management believes that both the Company and American River Bank met all their
capital adequacy requirements as of September 30, 2004 and December 31, 2003.

Off-Balance Sheet Items

         The Company is a party to financial instruments with off-balance-sheet
risk in the normal course of business in order to meet the financing needs of
its customers and to reduce its exposure to fluctuations in interest rates.
These financial instruments consist of commitments to extend credit and letters

                                       25


of credit. These instruments involve, to varying degrees, elements of credit and
interest rate risk in excess of the amount recognized on the balance sheet.

         The Company's exposure to credit loss in the event of nonperformance by
the other party for commitments to extend credit and letters of credit is
represented by the contractual amount of those instruments. The Company uses the
same credit policies in making commitments and letters of credit as it does for
loans included on the consolidated balance sheet. As of September 30, 2004 and
December 31, 2003, commitments to extend credit and letters of credit were the
only financial instruments with off-balance sheet risk. The Company has not
entered into any contracts for financial derivative instruments such as futures,
swaps, options or similar instruments. Loan commitments and letters of credit
were $80,135,000 and $72,599,000 at September 30, 2004 and December 31, 2003,
respectively. As a percentage of net loans and leases these off-balance sheet
items represent 29.9% and 27.7%, respectively.

         The Company has certain ongoing commitments under operating leases.
These commitments do not significantly impact operating results.

         Certain financial institutions have elected to use special purpose
vehicles ("SPV") to dispose of problem assets. The SPV is typically a subsidiary
company with an asset and liability structure and legal status that makes its
obligations secure even if the parent corporation goes bankrupt. Under certain
circumstances, these financial institutions may exclude the problem assets from
their reported impaired and non-performing assets. The Company does not use
these vehicles or any other structures to dispose of problem assets.

Other Matters

         Effects of Terrorism. The terrorist actions on September 11, 2001 and
thereafter and the current military conflict in Iraq have had significant
adverse effects upon the United States economy. Whether the terrorist activities
in the future and the actions of the United States and its allies in combating
terrorism on a worldwide basis will adversely impact the Company and the extent
of such impact is uncertain. However, such events have had and may continue to
have an adverse effect on the economy in the Company's market areas. Such
continued economic deterioration could adversely affect the Company's future
results of operations by, among other matters, reducing the demand for loans and
other products and services offered by the Company, increasing nonperforming
loans and the amounts reserved for loan and lease losses, and causing a decline
in the Company's stock price.

         Website Access. American River Bankshares maintains a website where
certain information about the Company is posted. Through the website, its annual
report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form
8-K, and amendments thereto are available as soon as reasonably practicable
after such material is electronically filed with or furnished to the Securities
and Exchange Commission (the "SEC"). These reports are free of charge and can be
accessed through the address www.amrb.com by clicking on the SEC Filings link
located at that address.

         Proposed Merger Transaction with Bank of Amador. On July 9, 2004, the
Company and Jackson, California-based Bank of Amador, announced jointly the
signing of an Agreement and Plan of Reorganization and Merger dated July 8,
2004, whereby the Company will acquire Bank of Amador through the merger of Bank
of Amador with and into American River Bank. Based upon American River
Bankshares' closing price of $20.40 as of July 8, 2004, the transaction is
currently valued at approximately $19.50 per share, or $30.5 million for Bank of
Amador shareholders. Upon completion of the transaction, Bank of Amador will
operate as a division of American River Bank under the name "Bank of Amador, a
division of American River Bank." The Board of Directors of both companies
unanimously approved the definitive agreement. The transaction is subject to
regulatory approvals and the approval by the shareholders of American River
Bankshares and Bank of Amador. On September 17, 2004, the Company filed a
registration statement of Form S-4 with the SEC that included a description of
the proposed merger and the Agreement and Plan of Reorganization and Merger and
exhibits thereto. The Form S-4 can be accessed through the Company's website by
following the steps referenced above in the "Website Access" section. The
transaction is expected to close in the fourth quarter of 2004.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk Management

         Overview. Market risk is the risk of loss from adverse changes in
market prices and rates. The Company's market risk arises primarily from
interest rate risk inherent in its loan, investment and deposit functions. The
goal for managing the assets and liabilities of the Company is to maximize
shareholder value and earnings while maintaining a high quality balance sheet
without exposing the Company to undue interest rate risk. The Board of Directors
has overall responsibility for the interest rate risk management policies. The
Company has a Risk Management Committee, made up of Company management that
establishes and monitors guidelines to control the sensitivity of earnings to
changes in interest rates.

         Asset/Liability Management. Activities involved in asset/liability
management include but are not limited to lending, accepting and placing
deposits and investing in securities. Interest rate risk is the primary market
risk associated with asset/liability management. Sensitivity of earnings to
interest rate changes arises when yields on assets change in a different time
period or in a different amount from that of interest costs on liabilities. To
mitigate interest rate risk, the structure of the balance sheet is managed with
the goal that movements of interest rates on assets and liabilities are
correlated and contribute to earnings even in periods of volatile interest
rates. The asset/liability management policy sets limits on the acceptable
amount of variance in net interest margin and market value of equity under
changing interest environments. The Company uses simulation models to forecast
earnings, net interest margin and market value of equity.

         Simulation of earnings is the primary tool used to measure the
sensitivity of earnings to interest rate changes. Using computer-modeling
techniques, the Company is able to estimate the potential impact of changing
interest rates on earnings. A balance sheet forecast is prepared quarterly using
inputs of actual loans, securities and interest bearing liabilities (i.e.
deposits/borrowings) positions as the beginning base. The forecast balance sheet
is processed against three interest rate scenarios. The scenarios include a 200
basis point rising rate forecast, a flat rate forecast and a 200 basis point
falling rate forecast which take place within a one year time frame. The net
interest income is measured during the year assuming a gradual change in rates
over the twelve-month horizon. The Company's net interest income, as forecast
below, was modeled utilizing a forecast balance sheet projected from balances as
of the date indicated. Table Nine below summarizes the effect on net interest
income (NII) of a +/-200 basis point change in interest rates as measured
against a constant rate (no change) scenario.

September 30, 2004 and December 31, 2003

         The simulations of earnings do not incorporate any management actions,
which might moderate the negative consequences of interest rate deviations.
Therefore, they do not reflect likely actual results, but serve as conservative
estimates of interest rate risk.

                                       27

Inflation

         The impact of inflation on a financial institution differs
significantly from that exerted on manufacturing, or other commercial concerns,
primarily because its assets and liabilities are largely monetary. In general,
inflation primarily affects the Company and it subsidiaries through its effect
on market rates of interest, which affects the Company's ability to attract loan
customers. Inflation affects the growth of total assets by increasing the level
of loan demand, and potentially adversely affects capital adequacy because loan
growth in inflationary periods can increase at rates higher than the rate that
capital grows through retention of earnings which may be generated in the
future. In addition to its effects on interest rates, inflation increases
overall operating expenses. Inflation has not had a material effect upon the
results of operations of the Company and its subsidiaries during the periods
ended September 30, 2004 and 2003.

Liquidity

         Liquidity management refers to the Company's ability to provide funds
on an ongoing basis to meet fluctuations in deposit levels as well as the credit
needs and requirements of its clients. Both assets and liabilities contribute to
the Company's liquidity position. Federal funds lines, short-term investments
and securities, and loan repayments contribute to liquidity, along with deposit
increases, while loan funding and deposit withdrawals decrease liquidity. The
Company assesses the likelihood of projected funding requirements by reviewing
historical funding patterns, current and forecasted economic conditions and
individual client funding needs. Commitments to fund loans and outstanding
letters of credit at September 30, 2004 and December 31, 2003 were approximately
$78,138,000 and $1,997,000 and $71,858,000 and $741,000, respectively. Such
loans relate primarily to revolving lines of credit and other commercial loans,
and to real estate construction loans. Since some of the commitments are
expected to expire without being drawn upon, the total commitment amounts do not
necessarily represent future cash requirements.

         The Company's sources of liquidity consist of cash and due from
correspondent banks, overnight funds sold to correspondent banks, unpledged
marketable investments and loans held for sale and/or pledged for secured
borrowings. On September 30, 2004, consolidated liquid assets totaled $65.4
million or 14.3% of total assets compared to $56.8 million or 14.3% of total
assets on December 31, 2003. In addition to liquid assets, the Company maintains
short-term lines of credit in the amount of $48,000,000 with correspondent
banks. At September 30, 2004, the Company had $48,000,000 available under these
credit lines. Additionally, American River Bank is member of the Federal Home
Loan Bank (the "FHLB"). At September 30, 2004, American River Bank could have
arranged for up to $54,915,000 in secured borrowings from the FHLB. These
borrowings are secured by pledged mortgage loans and investment securities. At
September 30, 2004, the Company had advances, borrowings and commitments
outstanding of $38,536,000, leaving $16,379,000 available under these secured
borrowing arrangements. American River Bank also has informal agreements with
various other banks to sell participations in loans, if necessary. The Company
serves primarily a business and professional customer base and, as such, its
deposit base is susceptible to economic fluctuations. Accordingly, management
strives to maintain a balanced position of liquid assets to volatile and
cyclical deposits.

         Liquidity is also affected by portfolio maturities and the effect of
interest rate fluctuations on the marketability of both assets and liabilities.
The Company can sell any of its unpledged securities held in the
available-for-sale category to meet liquidity needs. Due to the falling interest
rate environment throughout the last half of 2000 and continuing through the end
of 2003, much of the investment portfolio experienced price appreciation, which
has resulted in unrealized gains. During the last part of the second half of the
second quarter of 2004, the bond market experienced an overall drop in price due
to an increase in rates; however, during the third quarter of 2004, interest
rates rose in the 3 to 5 year range where the Company holds a great percentage
of its investment securities and as a result the investment portfolio maintained
a large part of the unrealized gains. These unrealized gains allow the Company
the ability to sell these securities should the liquidity needs arise. These
securities are also available to pledge as collateral for borrowings if the need
should arise. American River Bank has established a master repurchase agreement
with a correspondent bank to enable such transactions. American River Bank can
also pledge securities to borrow from the Federal Reserve Bank of San Francisco

                                       28


and the FHLB. The principal cash requirements of the Company are for expenses
incurred in the support of administration and operations. For nonbanking
functions, the Company is dependent upon the payment of cash dividends from
American River Bank to service its commitments. The Company expects that the
cash dividends paid by American River Bank to the Company will be sufficient to
meet this payment schedule.

Item 4. Controls and Procedures.

         (a) Disclosure Controls and Procedures: An evaluation of the Company's
disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e)
and 15d-15(e)) was carried out under the supervision and with the participation
of the Company's Chief Executive Officer, Chief Financial Officer and other
members of the Company's senior management as of the end of the period covered
by this quarterly report on Form 10-Q. The Company's Chief Executive Officer and
Chief Financial Officer concluded that the Company's disclosure controls and
procedures as currently in effect are effective in ensuring that the information
required to be disclosed by the Company in the reports it files or submits under
the Exchange Act is (i) accumulated and communicated to the Company's management
(including the Chief Executive Officer and Chief Financial Officer) to allow
timely decisions regarding required disclosure, and (ii) recorded, processed,
summarized and reported within the time periods specified in the Commission's
rules and forms.

         (b) Internal Control Over Financial Reporting: An evaluation of any
changes in the Company's internal control over financial reporting (as defined
in Exchange Act Rules 13a-15(f) and 15d-15(f)), that occurred during the
Company's fiscal quarter ended September 30, 2004, was carried out under the
supervision and with the participation of the Company's Chief Executive Officer,
Chief Financial Officer and other members of the Company's senior management.
The Company's Chief Executive Officer and Chief Financial Officer concluded that
no change identified in connection with such evaluation has materially affected,
or is reasonably likely to materially affect, the Company's internal control
over financial reporting.

         On September 20, 2001, the Board of Directors of the Company authorized
a stock repurchase program which calls for the repurchase of up to five percent
(5%) annually of the Company's outstanding shares of common stock. Each year the
Company may repurchase up to 5% of the shares outstanding (adjusted for stock
splits or stock dividends). The 200,646 shares reported in the table as shares
that may be repurchased under the plan represent shares eligible for the
calendar year 2004. The repurchases are to be made from time to time in the open
market as conditions allow and will be structured to comply with Commission Rule
10b-18. The Board of Directors has reserved the right to suspend, terminate,
modify or cancel this repurchase program at any time for any reason.
