              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 2008

1. 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 June 30, 2008 and December 31, 2007, and the
results of its operations for the three-month and six-month periods ended June
30, 2008 and 2007 and its cash flows for the six-month periods ended June 30,
2008 and 2007 in conformity with accounting principles generally accepted in the
United States of America.

Certain disclosures normally presented in the notes to the annual consolidated
financial statements prepared in accordance with accounting principles generally
accepted in the United States of America have been omitted. The Company believes
that the disclosures are adequate to make the information not misleading. These
interim consolidated financial statements should be read in conjunction with the
consolidated financial statements and notes thereto included in the Company's
2007 annual report on Form 10-K. The results of operations for the three-month
and six-month periods ended June 30, 2008 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.

Management has determined that since all of the banking products and services
offered by the Company are available in each branch of American River Bank, all
branches are located within the same economic environment and management does
not allocate resources based on the performance of different lending or
transaction activities, it is appropriate to aggregate all of the branches and
report them as a single operating segment. No client accounts for more than ten
percent (10%) of revenues for the Company or American River Bank.

2. STOCK-BASED COMPENSATION

Stock Option Plans

In 2000 and 1995, the Board of Directors adopted stock option plans under which
options may be granted to employees and directors under incentive and
nonstatutory agreements. The plans require that the option price may not be less
than the fair market value of the stock at the date the option is granted. The
options under the plans expire on dates determined by the Board of Directors,
but not later than ten years from the date of grant. The vesting period is
generally five years; however the vesting period can be modified at the
discretion of the Company's Board of Directors. Outstanding options under the
plans are exercisable until their expiration. New shares are issued upon
exercise.

Stock Option Compensation

The weighted average grant date fair value of options granted for the three
month period ended June 30, 2008 was $2.08. There were no stock options granted
during the three-month period ended June 30, 2007. The weighted average grant
date fair value of options granted for the six-month periods ended June 30, 2008
and 2007 was $2.89 and $6.06, respectively. For the three-month periods ended
June 30, 2008 and 2007, the compensation cost recognized for stock option
compensation was $74,000 and $80,000, respectively. For the six-month periods
ended June 30, 2008 and 2007, the compensation cost recognized for stock option
compensation was $142,000 and 141,000, respectively. The recognized tax benefit
for stock option compensation expense was $9,000 and $13,000, for the
three-month periods ended June 30, 2008 and 2007, respectively. The recognized
tax benefit for stock option compensation expense was $17,000 and $24,000, for
the six-month periods ended June 30, 2008 and 2007, respectively. At June 30,

                                       8
<PAGE>

2008, the total compensation cost related to nonvested awards not yet recorded
is expected to be $865,000. This amount will be recognized over the next five
years and the weighted average period of recognizing these costs is expected to
be 3.3 years.

 Stock Option Activity

A summary of option activity under the stock option plans as of June 30, 2008
and changes during the period then ended is presented below:

</TABLE>

The intrinsic value was derived from the market price of the Company's common
stock of $9.86 as of June 30, 2008.

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 $92,686,000 and standby letters of credit of
approximately $6,665,000 at June 30, 2008. Such loans relate primarily to real
estate construction loans and revolving lines of credit and other commercial
loans. However, all such commitments will not necessarily culminate in actual
extensions of credit by the Company during 2008 as some of these are expected to
expire without being fully drawn upon.

Standby letters of credit are commitments issued to guarantee the performance or
financial obligation of a client to a third party. These guarantees are issued
primarily relating to purchases of inventory or as security for real estate
rents by commercial clients and are typically short-term in nature. Credit risk
is similar to that involved in extending loan commitments to clients and
accordingly, evaluation and collateral requirements similar to those for loan
commitments are used. The majority of all such commitments are collateralized.
The fair value of the liability related to these standby letters of credit,
which represents the fees received for issuing the guarantees was not
significant at June 30, 2008 or June 30, 2007.

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 (5,534,837 and 5,547,968 shares
for the three-month and six-month periods ended June 30, 2008, and 5,799,742 and
5,821,232 shares for the three-month and six-month periods ended June 30, 2007).
Diluted earnings per share reflect the potential dilution that could occur if
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 (14,024 and 22,541 shares for the
three-month and six-month periods ended June 30, 2008 and 68,856 and 75,598
shares for the three-month and six-month periods ended June 30, 2007). 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 comprised of net income plus other
comprehensive income (loss). Other comprehensive loss, net of taxes, was
comprised of the unrealized losses on available-for-sale investment securities
of $(641,000) and $(137,000), respectively, for the three-month and six-month
periods ended June 30, 2008 and $(330,000) and $(133,000), respectively, for the
three-month and six month periods ended June 30, 2007. Comprehensive income was
$1,340,000 and $3,677,000, respectively, for the three-month and six-month
periods ended June 30, 2008 and $1,768,000 and $4,051,000, respectively, for the
three-month and six-month periods ended June 30, 2007. Reclassification
adjustments resulting from realized gain or loss on sale of investment
securities were not significant for all periods presented.

6. BORROWING ARRANGEMENTS

The Company has a total of $52,000,000 in unsecured short-term borrowing
arrangements with three of its correspondent banks. There were no advances under
the borrowing arrangements as of June 30, 2008 or December 31, 2007.

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 (both short and long-term) totaling
$53,803,000 were outstanding from the FHLB at June 30, 2008, bearing interest
rates ranging from 1.81% to 4.44% and maturing between July 1, 2008 and October
19, 2010. Advances totaling $51,603,000 were outstanding from the FHLB at
December 31, 2007, bearing interest rates ranging from 3.25% to 5.21% and
maturing between January 2, 2008 and October 30, 2008. Remaining amounts
available under the borrowing arrangement with the FHLB at June 30, 2008 and
December 31, 2007 totaled $65,772,000 and $79,631,000, respectively.

7. INCOME TAXES

The Company files its income taxes on a consolidated basis with its
subsidiaries. The allocation of income tax expense (benefit) represents each
entity's proportionate share of the consolidated provision for income taxes.

The Company accounts for income taxes using the balance sheet method, under
which deferred tax assets and liabilities are recognized for the tax
consequences of temporary differences between the reported amounts of assets and
liabilities and their tax bases. Deferred tax assets and liabilities are
adjusted for the effects of changes in tax laws and rates on the date of
enactment. On the consolidated balance sheet, net deferred tax assets are
included in accrued interest receivable and other assets.

The benefit of a tax position is recognized in the financial statements in the
period during which, based on all available evidence, management believes it is
more likely than not that the position will be sustained upon examination,
including the resolution of appeals or litigation processes, if any. Tax
positions that meet the more-likely-than-not recognition threshold are measured
as the largest amount of tax benefit that is more than 50 percent likely of
being realized upon settlement with the applicable taxing authority. The portion
of the benefits associated with tax positions taken that exceeds the amount
measured as described above is reflected as a liability for unrecognized tax
benefits in the accompanying balance sheet along with any associated interest
and penalties that would be payable to the taxing authorities upon examination.
The Company recognizes accrued interest and penalties related to unrecognized
tax benefits, if applicable, as a component of interest expense in the
consolidated statements of income. There have been no significant changes to
unrecognized tax benefits or accrued interest and penalties for the three and
six-month periods ended June 30, 2008.

8. FAIR VALUE MEASUREMENT

On January 1, 2008, the Company adopted Financial Accounting Standards Board
(FASB) Statement No. 157 (SFAS 157), "Fair Value Measurements." SFAS 157 defines
fair value, establishes a framework for measuring fair value under accounting
principles generally accepted in the United States of America and expands
disclosures about fair value measurements. There was no cumulative effect
adjustment to beginning retained earnings recorded upon adoption and no impact
on the financial statements in the first six months of 2008.

The following table presents information about the Company's assets and
liabilities measured at fair value on a recurring and nonrecurring basis as of
June 30, 2008, and indicates the fair value hierarchy of the valuation
techniques utilized by the Company to determine such fair value. In general,
fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in
active markets for identical assets or liabilities that the Company has the
ability to access. Fair values determined by Level 2 inputs utilize information
other than the quoted prices included in Level 1 that are observable for the
asset or liability, either directly or indirectly. Level 2 inputs include quoted
prices for similar assets and liabilities in active markets, and inputs other
than quoted prices that are observable for the asset or liability, such as
interest rates and yield curves that are observable at commonly quoted
intervals. Level 3 inputs are unobservable inputs for the asset or liability,
and include situations where there is little, if any, market activity for the
asset or liability. In certain cases, the inputs used to measure fair value may
fall into different levels of the fair value hierarchy. In such cases, the level
in the fair value hierarchy within which the fair value measurement, in its
entirety, falls has been determined based on the lowest level input that is
significant to the fair value measurement. The Company's assessment of the
significance of a particular input to the fair value measurement, in its
entirety, requires judgment and considers factors specific to the asset or
liability.

The following methods were used to estimate the fair value of each class of
financial instrument above:

Available-for-sale securities - Fair values for investment securities are based
on evaluated pricing models that vary by asset class and incorporate available
trade, bid and other market information. Evaluated pricing applications apply
available information, as applicable, through processes such as benchmark
curves, benchmarking to like securities, sector groupings, and matrix pricing.

Impaired Loans - The fair value of impaired loans is based on the fair value of
the collateral for all collateral dependent loans and for other impaired loans
is estimated using a discounted cash flow model.

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 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 factors that we
use. 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 Accounting Standards
("SFAS") No. 5 "Accounting for Contingencies," which requires that losses be
accrued when it is probable that a loss has occurred at the balance sheet date
and such loss can be reasonably estimated; and (2) SFAS No. 114, "Accounting by
Creditors for Impairment of a Loan," which requires that losses be accrued on
impaired loans 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.

         The allowance for loan and lease losses is determined based upon
estimates that can and do change when the actual risk, loss events, or changes
in other factors, 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. If the allowance for loan and lease losses falls below
that deemed adequate (by reason of loan and lease growth, actual losses, the
effect of changes in risk factors, or some combination of these), the Company
has a strategy for supplementing the allowance for loan and lease losses, over
the short-term. For further information regarding our allowance for loan and
lease losses, see "Allowance for Loan and Lease Losses Activity" discussion
later in this Item 2.

Stock-Based Compensation

         The Company recognizes compensation expense in an amount equal to the
fair value of the share-based payments such as stock options granted to
employees. The Company records compensation expense (as previous awards continue
to vest) for the unvested portion of previously granted awards that were
outstanding on January 1, 2006 and for all awards granted after that date as
they vest. The fair value of each option is estimated on the date of grant and
amortized over the service period using an option pricing model. Critical
assumptions that affect the estimated fair value of each option include expected
stock price volatility, dividend yields, option life and the risk-free interest
rate.

Goodwill

         Business combinations involving the Company's acquisition of the equity
interests or net assets of another enterprise or the assumption of net
liabilities in an acquisition of branches constituting a business may give rise
to goodwill. Goodwill represents the excess of the cost of an acquired entity
over the net of the amounts assigned to assets acquired and liabilities assumed
in transactions accounted for under the purchase method of accounting. The value
of goodwill is ultimately derived from the Company's ability to generate net
earnings after the acquisition. A decline in net earnings could be indicative of
a decline in the fair value of goodwill and result in impairment. For that
reason, goodwill is assessed for impairment at a reporting unit level at least
annually following the year of acquisition. The Company performed an evaluation
of the goodwill, recorded as a result of the Bank of Amador acquisition, during
the fourth quarter of 2007 and determined that there was no impairment. While
the Company believes all assumptions utilized in its assessment of goodwill for
impairment are reasonable and appropriate, changes in earnings, the effective
tax rate, historical earnings multiples and the cost of capital could all cause
different results for the calculation of the present value of future cash flows.

Fair Value

         Effective January 1, 2008, the Company adopted SFAS No. 157, "Fair
Value Measurements," which among other things, requires enhanced disclosures
about financial instruments carried at fair value. SFAS No. 157 establishes a
hierarchical disclosure framework associated with the level of observable
pricing scenarios utilized in measuring financial instruments at fair value. The
degree of judgment utilized in measuring the fair value of financial instruments
generally correlates to the level of the observable pricing scenario. Financial
instruments with readily available active quoted prices or for which fair value
can be measured from actively quoted prices generally will have a higher degree
of observable pricing and a lesser degree of judgment utilized in measuring fair
value. Conversely, financial instruments rarely traded or not quoted will
generally have little or no observable pricing and a higher degree of judgment
utilized in measuring fair value. Observable pricing scenarios are impacted by a
number of factors, including the type of financial instrument, whether the
financial instrument is new to the market and not yet established and the
characteristics specific to the transaction.


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
the State of California in 1995. As a bank holding company, the Company is
authorized to engage in the activities permitted under the Bank Holding Company
Act of 1956, as amended, and regulations thereunder. Its principal office is
located at 3100 Zinfandel Drive, Suite 450, Rancho Cordova, California 95670 and
its telephone number is (916) 854-0123. The Company employed an equivalent of
121 full-time employees as of June 30, 2008.

         The Company owns 100% of the issued and outstanding common shares of
its banking subsidiary, American River Bank (the "Bank"), and American River
Financial, a California corporation which has been inactive since its
incorporation in 2003.

         American River Bank was incorporated and commenced business in Fair
Oaks, California, in 1983 and thereafter moved its headquarters to Sacramento,
California in 1985. American River Bank operates: (1) five full service offices
and one convenience office in Sacramento and Placer Counties including the head
office located at 1545 River Park Drive, Suite 107, Sacramento, and branch
offices located at 520 Capitol Mall, Suite 100, Sacramento, 9750 Business Park
Drive, Sacramento, 10123 Fair Oaks Boulevard, Fair Oaks and 2240 Douglas
Boulevard, Roseville, and the convenience office (limited service office)
located at 3100 Zinfandel Drive, Suite 450, Rancho Cordova, and (2) three full
service offices in Sonoma County located at 412 Center Street, Healdsburg, 8733
Lakewood Drive, Windsor, and 50 Santa Rosa Avenue, Suite 100, Santa Rosa,
operated under the name "North Coast Bank, a division of American River Bank."
North Coast Bank was acquired by the Company in 2000 as a separate bank
subsidiary and was merged with and into American River Bank in 2003. The Company
acquired Bank of Amador located in Jackson, California in 2004. Bank of Amador
was merged with and into American River Bank and now operates three full service
banking offices as "Bank of Amador, a division of American River Bank" within
its primary service area of Amador County, in the cities of Jackson, Pioneer and
Ione.

         The Bank's deposits are insured by the Federal Deposit Insurance
Corporation (the "FDIC") up to applicable legal limits. The Bank does not offer
trust services or international banking services and does not plan to do so in
the near future. The Bank's primary business is serving the commercial banking
needs of small to mid-sized businesses within those counties listed above. The
Bank accepts checking and savings deposits, offers money market deposit accounts
and certificates of deposit, makes secured and unsecured commercial, secured
real estate, and other installment and revolving credit loans and offers other
customary banking services. The Bank also conducts lease financing for most
types of business equipment, from computer software to heavy earth-moving
equipment. The Bank owns 100% of two inactive companies, ARBCO and American
River Mortgage. ARBCO was formed in 1984 to conduct real estate development and
has been inactive since 1995. American River Mortgage has been inactive since
its formation in 1994.

         During 2008, 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
"Board of Governors"), the Company's principal regulator, to engage in a variety
of activities which are deemed closely related to the business of banking. The
common stock of the Company is registered under the Securities Exchange Act of
1934, as amended, and is listed and traded on the Nasdaq Global Select Market
under the symbol "AMRB."

Results of Operations

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 interest-bearing
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 4.99% for the three months ended June 30, 2008, 5.10% for the three
months ended June 30, 2007, 4.96% for the six months ended June 30, 2008 and
5.07% for the six months ended June 30, 2007.

         The fully taxable equivalent interest income component for the second
quarter of 2008 decreased $1,247,000 (13.0%) to $8,340,000 compared to
$9,587,000 for the three months ended June 30, 2007. Total fully taxable
equivalent interest income for the six months ended June 30, 2008 decreased
$2,137,000 (11.2%) to $17,003,000 compared to $19,140,000 for the six months
ended June 30, 2007. The decrease in the fully taxable equivalent interest
income for the second quarter of 2008 compared to the same period in 2007 is
broken down by rate (down $1,332,000) and volume (up $85,000). The decline in
rates can be attributed to decreases implemented by the Company during the
latter part of 2007 and the first half of 2008 in response to the Federal
Reserve Board (the "FRB") decreases in the Federal funds and discount rates.
Decreases by the FRB have resulted in seven rate reductions totaling 325 basis
points since September 2007. In addition, an increased level of nonaccrual loans
resulted in foregone interest income of approximately $260,000 during the second
quarter of 2008. The overall decreasing interest rate environment and the
negative effect of the nonaccrual loans resulted in an 88 basis point decrease
in the yield on average earning assets from 7.30% for 2007 to 6.42% for 2008.
The volume increase occurred despite a slight (0.8%) decrease in average earning
assets as a result of a shift in balances from lower earning investments to
higher earning loans. The decrease in average earning assets resulted from the
Company's decision to use the proceeds from principal reductions and maturing
investment securities to reduce the level of higher cost time deposits and
provide funding for loan growth. This strategy has reduced the average balances
on investment securities by $19,983,000 or 15.2% from $131,292,000 during the
second quarter of 2007 to $111,309,000 during the second quarter of 2008, while
average loan balances increased $14,786,000 or 3.8% from $390,311,000 during the
second quarter of 2007 to $405,097,000 during the second quarter of 2008. The
increase in average loans is the result of the Company's continued concentrated
focus on business lending.

         The breakdown of the fully taxable equivalent interest income for the
six months ended June 30, 2008 over the same period in 2007 resulted from
decreases in rate (down $2,246,000) and an increase in volume (up $109,000).
Average earning assets decreased $7,157,000 (1.3%) during the first six months
of 2008 as compared to the same period in 2007. Average loan balances increased
$15,439,000 (4.0%) during that same period and average investment securities
balances decreased $23,072,000 (16.9%).

         Interest expense was $1,032,000 (35.7%) lower in the second quarter of
2008 versus the prior year period. The average balances of interest-bearing
liabilities were $17,022,000 (4.7%) higher in the second quarter of 2008 versus
the same quarter in 2007. The higher balances accounted for a $255,000 increase
in interest expense. Average borrowings were up $21,362,000 (66.7%) as the
Company focused on reducing the higher cost time deposits and replacing them
with lower cost other borrowings. Average time deposits were down $1,016,000 or
0.8% from $123,887,000 during the second quarter of 2007 to $122,871,000 during
the second quarter of 2008. The drop in time deposits was offset by the
Company's decision to bring in another $7,500,000 in low cost time deposits from
the State of California at a rate of 1.64%. Decreased rates accounted for a
$1,287,000 reduction in interest expense for the three-month period ended June
30, 2008. The decrease in rates is a direct result of the lower overall rate
environment. Rates paid on interest-bearing liabilities decreased 122 basis
points from the second quarter of 2007 to the second quarter of 2008 from 3.18%
to 1.96%. The rate on average borrowings dropped 228 basis points during that
same time period from 5.24% to 2.96%.

         Interest expense was $1,713,000 (29.5%) lower in the six-month period
ended June 30, 2008 versus the prior year period. The average balances on
interest-bearing liabilities were $11,722,000 (3.2%) higher in the six-month
period ended June 30, 2008 versus the same period in 2007. The higher balances,
especially in the level of average borrowings, accounted for a $350,000

                                       16
<PAGE>

increase in interest expense. This increase was offset by lower rates, which
accounted for a $2,063,000 decrease in interest expense for the six-month
period. Rates paid on interest-bearing liabilities decreased 101 basis points
from the first six months of 2007 to the first six months of 2008 from 3.18% to
2.17%.

Provision for Loan and Lease Losses

         The Company provided $190,000 for loan and lease losses for the second
quarter of 2008 as compared to $144,000 for the second quarter of 2007. Net loan
and lease losses for the three months ended June 30, 2008 were $96,000 or .10%
(on an annualized basis) of average loans and leases as compared to $107,000 or
0.11% (on an annualized basis) of average loans and leases for the three months
ended June 30, 2007. For the first six months of 2008, the Company made
provisions for loan and lease losses of $527,000 and net loan and lease losses
were $299,000 or .15% (on an annualized basis) of average loans and leases
outstanding. This compares to provisions for loan and lease losses of $265,000
and net loan and lease losses of $167,000 for the first six months of 2007 or
..09% (on an annualized basis) of average loans and leases outstanding. For

--------------------------------------------------------------------------------------------------------
</TABLE>

         Noninterest income decreased $85,000 (11.7%) to $639,000 for the three
months ended June 30, 2008 as compared to $724,000 for the three months ended
June 30, 2007. For the six months ended June 30, 2008, noninterest income
decreased $141,000 (10.3%) to $1,224,000. The decrease from the second quarter
of 2007 to the second quarter of 2008 was primarily related to lower service
charges on deposit accounts (down $34,000 or 16.7%) and lower income from fees
on residential lending (down $55,000 or 32.4%). The decrease in service charges
on deposit accounts is a result of a new service fee structure that was put in
place in the third quarter of 2007 and the decrease in fees from residential
lending resulted from the lower number of loan closings due to the slowdown in
the residential real estate market. The decrease from the first six months of
2007 to the same period in 2008 was primarily related to lower service charges
on deposit accounts (down $43,000 or 10.8%) and lower income from fees on
residential lending (down $50,000 or 21.3%).

Noninterest Expense

         Noninterest expense decreased $137,000 (3.6%) to a total of $3,642,000
in the second quarter of 2008 versus $3,779,000 in the second quarter of 2007.
Salary and employee benefit expense decreased $69,000 (3.2%) from $2,142,000
during the second quarter of 2007 to $2,073,000 during the second quarter of
2008. Most of this decrease resulted from a reduction in the number of full-time
equivalent employees. Average full-time equivalent employees dropped from 130
during the second quarter of 2007 to 123 during the second quarter of 2008. On a
quarter-over-quarter basis, occupancy expense increased by $24,000 (7.0%) and
furniture and equipment expense increased $32,000 (19.2%). The increase in
occupancy and furniture and equipment expenses resulted from normal rent
increases and higher technology related maintenance. Other expense decreased
$124,000 (11.0%) to a total of $1,004,000 in the second quarter of 2008 compared
to $1,128,000 in the second quarter of 2007. The efficiency ratios (fully
taxable equivalent), excluding the amortization of intangible assets, for the
2008 and 2007 second quarters were 50.1% and 49.9%, respectively.

                                       20
<PAGE>

         Noninterest expense for the six-month period ended June 30, 2008 was
$7,271,000 versus $7,471,000 for the same period in 2007 for a decrease of
$200,000 (2.7%). Salaries and benefits expense decreased $173,000 (4.1%) from
$4,267,000 for the six months ended June 30, 2007 to $4,094,000 for the same
period in 2008. The decrease resulted from a reduction in the number of
full-time equivalent employees. Occupancy expense increased $47,000 (6.9%) and
furniture and equipment expense increased $59,000 (17.8%). The increase in
occupancy and furniture and equipment expenses resulted from normal rent
increases and higher technology related maintenance. Other expense decreased
$133,000 (6.1%) from $2,190,000 for the six months ended June 30, 2007 to
$2,057,000 for the same period in 2008. The overhead efficiency ratio (fully
taxable equivalent), excluding the amortization of intangible assets, for the
first six months of 2008 was 50.4% as compared to 49.8% in the same period of
2007.

Provision for Income Taxes

         Federal and State income taxes for the second quarter of 2008 decreased
$91,000 (6.9%) to $1,221,000 from $1,312,000 for the second quarter of 2007. For
the first six months of 2008, Federal and State income taxes decreased $288,000
(12.3%) from the first six months of 2007. The decreases were a result of the
lower income as the effective Federal and State tax rate for the second quarter
and first six months of 2008 remained consistent at 38.1%, versus 38.3% and
38.5%, respectively, for the same two periods of 2007.

Balance Sheet Analysis

         The Company's total assets were $580,350,000 at June 30, 2008 as
compared to $573,685,000 at December 31, 2007, representing an increase of 1.2%.
The average assets for the six months ended June 30, 2008 were $574,879,000,
which represents a decrease of $7,882,000 or 1.4% from the balance of
$582,761,000 during the six-month period ended June 30, 2007. The average assets
for the second quarter of 2008 were $575,827,000 compared to $576,812,000 during
the second quarter of 2007 a decrease of 0.2%. Although the overall decrease was
slight, there was a positive shift from investment securities to loans. Average
loans increased $15,786,000 (4.0%) from the second quarter of 2007 to the second
quarter of 2008, while average investment securities decreased $19,983,000
(15.2%) during the same time period. The Company chose to utilize the proceeds
from matured and pay downs of investment securities as a funding source for the
growth in the loans.

Investment Securities

         The Company classifies its investment securities as available-for-sale
or held-to-maturity. The Company's intent is to hold all securities classified
as held-to-maturity until maturity and management believes that it has the
ability to do so. Securities available-for-sale may be sold to implement
asset/liability management strategies and in response to changes in interest
rates, prepayment rates and similar factors. Table Five below summarizes the
values of the Company's investment securities held on June 30, 2008 and December
31, 2007.

         Management periodically evaluates each investment security in a loss
position for other than temporary impairment relying primarily on industry
analyst reports, observation of market conditions and interest rate
fluctuations. Management has the ability and intent to hold securities with
established maturity dates until recovery of fair value, which may be maturity,
and believes it will be able to collect all amounts due according to the
contractual terms for all of the underlying investment securities; therefore,
management does not consider these investments to be
other-than-temporarily-impaired.

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 June 30, 2008, these categories accounted for
approximately 27%, 48%, 2%, 14%, 3%, 1%, 2% and 3%, respectively, of the
Company's loan portfolio. This mix was relatively unchanged compared to 26%,
48%, 2%, 16%, 2%, 1%, 2% and 3% at December 31, 2007. Continuing marketing
efforts, particularly in the business banking field, resulted in new borrowers,
and credit extensions were expanded to existing borrowers resulting in the
Company originating $58,600,000 in new loans during the first six months of
2008. Total loans increased $7,636,000 (1.9%) from December 31, 2007. Table Six
below summarizes the composition of the loan portfolio as of June 30, 2008 and
December 31, 2007.

         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, both unsecured and home equity secured, 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 semi-custom
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%, and loans secured by commercial and residential land, both
finished and undeveloped, with maturities generally under 24 months and with
original loan to value ratios generally below 65%. Agriculture loans consist
primarily of vineyard loans and development loans to plant vineyards. In

                                       22

general, except in the case of loans under SBA programs or Farm Services Agency
guarantees, the Company does not make long-term mortgage loans; however, The
Bank has a residential lending division to assist customers in securing most
forms of longer term single-family mortgage financing. The Bank acts as a broker
between the Bank's clients and the loan wholesalers. The Bank receives an
origination fee for loans closed.

         Subprime real estate loans generally refer to residential mortgages
made to higher-risk borrowers with lower credit and/or income histories. Many of
these subprime loans were made with adjustable interest rates that reset upward
after an introductory period. Such subprime loans coupled with declines in
housing prices have led to an increase in default rates resulting in many
instances of increased foreclosure rates as the adjustable interest rates reset
to higher levels. The Company does not have any such "subprime" loans at June
30, 2008.

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 continually 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, in
Sonoma County, through North Coast Bank, a division of American River Bank,
whose business is focused on businesses within the three communities in which it
has offices (Santa Rosa, Windsor, and Healdsburg) and in Amador County, through
Bank of Amador, a division of American River Bank, whose business is focused on
businesses and consumers within the three communities in which it has offices
(Jackson, Pioneer, and Ione) as well as a diversified residential construction
loan business in numerous Northern California counties. The economy of Sonoma
County is diversified with professional services, manufacturing, agriculture and
real estate investment and construction, while the economy of Amador County is
reliant upon government, services, retail trade, manufacturing industries and
Indian gaming.

         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,
supply and demand factors, 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 66.9% of the Company's loan and lease portfolio
at June 30, 2008, down from 68.0% at December 31, 2007. Management believes that
the residential land and residential construction portion of the Company's loan
portfolio carries more credit risk than it has seen in the past several years,
due primarily to severely curtailed demand for new and resale residential
property, a large supply of unsold residential land and new and resale homes,
and observed reductions in values throughout the Company's market area.
Management has responded by evaluating loans that it considers to carry
additional risk above the normal risk of collectability, and by taking actions
where possible to reduce credit risk exposure by methods that include, but

                                       23
<PAGE>

are not limited to, seeking liquidation of the loan by the borrower, seeking
additional tangible collateral or other repayment support, converting the
property through judicial or non-judicial foreclosure proceedings, and other
collection techniques. Management currently believes that it maintains its
allowance for loan and lease losses at levels adequate to reflect the loss risk
inherent in its total loan portfolio. A substantial further decline in the
economy in general, or an additional decline in real estate values in the
Company's primary market areas in particular, could have a further 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) 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 or contracted third-party professionals.

Nonaccrual, Past Due and Restructured Loans and Leases

         Management generally places loans and leases on nonaccrual status when
they become 90 days past due, or if a loss is expected, unless the loan or lease
is well secured and in the process of collection. Loans and leases are charged
off when, in the opinion of management, collection appears unlikely.

         At June 30, 2008, non-performing loans and leases (those loans and
leases on nonaccrual status and those loans and leases still accruing and past
due 90 days or more) were $14,265,000 or 3.49% of total loans and leases.
Non-performing loans and leases were $7,440,000 or 1.86% of total loans and
leases at December 31, 2007. At June 30, 2008, four loan relationships made up
$12,131,000 or 85.0% of the non-performing assets. Of these four relationships,
three continue from last quarter: a $1,352,000 development loan for residential
lots, a $5,286,000 loan for a mini-storage facility, and $2,927,000 remaining on
multiple loans to a developer. The development loan in an approximate total
amount of $4.6 million is a loan in which the Company participates with other
lenders. The Company has a net 29% interest in the loan and a loan balance of
$1,352,000. The loan is a lot development loan for 29 single-family residential
lots, 47 townhouse lots and 3 commercial lots located in Amador County. The
mini-storage loan in the amount of $5,286,000 is a commercial loan for a
mini-storage facility in El Dorado County with an original loan to value ratio
from 2002 of 59.8% and a current appraisal that exceeds the carrying value of
the loan. In April 2008, the Company confirmed that the borrower on the
mini-storage facility loan had filed for reorganization under Chapter 11
bankruptcy. The business has appointed new management and the Company has
received current operating cash flow statements indicating the borrowers ability
to service the loan at a market rate of interest. Under a court-confirmed
agreement, the borrower made the two required interest payments during the
second quarter of 2008 and the Company has received one interest payment
subsequent to quarter end. These payments have been recorded as interest income.
The multiple loans to a developer totaled $3,734,000 at March 31, 2008. This
relationship was made up of eight individual loans and included loans on three
finished homes totaling $2,242,000; one partially completed home for $493,000,
and four finished lots for $999,000. In April 2008, the Company filed notices of
default on all eight properties. The filing of Chapter 11 bankruptcy by one of
the borrowers, subsequent to the Company's filing of the notices of default, has
delayed the foreclosure process. During the second quarter of 2008, one of the
loans, in the amount of $825,000, paid off and another in the amount of $504,000
paid off subsequent to quarter end. Both loans included full payment of
principal, interest and associated fees. Six loans remain from this
relationship--loans on two finished homes totaling $1,424,000 and loans on four
finished lots for $999,000. During the second quarter of 2008, the Company
identified and placed one additional significant loan to another borrower on
nonaccrual in the amount of $2,566,000. This loan is secured by an assignment of
a real estate secured note covering a former mobile home park, intended for
apartment development. The pledged note the Company accepted as collateral has a
balance of over $4 million. Management has filed suit against the borrower and
guarantors. Management believes this loan is adequately secured.

                                       24
<PAGE>

         All significant nonaccrual loans have been evaluated for impairment in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 114,
"Accounting by Creditors for Impairment of a Loan" and have been assigned
specific reserves as deemed necessary. At June 30, 2008, specific reserves in
the amount of $1,189,000 were held on the nonperforming loans considered to be
impaired. The Company considers a loan to be impaired when, based on current
information and events, it is probable that it will be unable to collect all
amounts due (principal and interest) according to the contractual terms of the
loan agreement. The measurement of impairment may be based on (i) the present
value of the expected cash flows of the impaired loan discounted at the loan's
original effective interest rate, (ii) the observable market price of the
impaired loan or (iii) the fair value of the collateral of a
collateral-dependent loan. The Company does not apply this definition to
smaller-balance loans that are collectively evaluated for credit risk. Interest
due but excluded from interest income on nonaccrual loans and leases was
$596,000 for the first six months of 2008 and not significant during the same
period in 2007. In the first six months of 2008, interest income recognized from
payments received on nonaccrual loans and leases was approximately $100,000 and
in the same period in 2007, the amount was not significant.

         There were no loan or lease concentrations in excess of 10% of total
loans and leases not otherwise disclosed as a category of loans and leases as of
June 30, 2008. Management is not aware of any potential problem loans, which
were accruing and current at June 30, 2008, where serious doubt exists as to the
ability of the borrower to comply with the present repayment terms and that
would result in a significant loss to the Company. Table Seven below sets forth
nonaccrual loans and loans past due 90 days or more as of June 30, 2008 and
December 31, 2007.

Allowance for Loan and Lease Losses Activity

         The Company maintains an allowance for loan and lease losses ("ALLL")
to cover probable 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 continually
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 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 and leases
which are 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) historical loss rates, (x) quarterly
review by the Board of Directors, and (xi) assessments by banking regulators and
other third parties. Management and the Board of Directors evaluate the ALLL
quarterly or more frequently and determine its appropriate level considering
objective and subjective measures, such as knowledge of the borrower's business,
valuation of collateral, the determination of impaired loans or leases and
exposure to potential losses.

                                       25
<PAGE>

         The allowance for loan and lease losses totaled $6,111,000 or 1.50% of
total loans and leases at June 30, 2008 compared to $5,883,000 or 1.47% of total
loans and leases at December 31, 2007. The Company establishes general reserves
in accordance with 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 and
lease 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 probable 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 ALLL
based on their judgment of information available to them at the time of their
examination.

         It is the policy of management to maintain the allowance for loan and
lease losses at a level believed to be adequate for known and inherent risks in
the portfolio. Our methodology incorporates a variety of risk considerations,
both quantitative and qualitative, in establishing an allowance for loan and
lease losses that management believes is appropriate at each reporting date.
Based on information currently available to analyze inherent credit risk,
including economic factors, overall credit quality, historical delinquencies and
a history of actual charge-offs, management believes that the allowance for loan
and lease losses is prudent and adequate. Adjustments may be made based on
differences from estimated loan and lease growth, the types of loans
constituting this growth, changes in risk ratings within the portfolio, and
general economic conditions. However, no prediction of the ultimate level of
loans and leases charged off in future periods can be made with any certainty.
Table Eight below summarizes, for the periods indicated, the activity in the
ALLL.

Other Real Estate

         At June 30, 2008, the Company did not have any other real estate
("ORE") properties, and at December 31, 2007, the Company had $61,000 in ORE.

Deposits

         At June 30, 2008, total deposits were $459,200,000 representing an
increase of $3,555,000 (0.8%) from the December 31, 2007 balance of
$455,645,000. Noninterest-bearing deposits decreased $4,946,000 (3.7%) from
December 31, 2007 to June 30, 2008, while interest-bearing deposits increased
$8,501,000 (2.6%) over that same period. The Company's deposit growth plan
continues to concentrate its efforts on increasing noninterest-bearing demand,
interest-bearing money market and NOW accounts, and savings accounts categories.
The Company experienced some success in the interest checking and savings
accounts with an increase of $4,122,000 (5.2%) in those accounts from December
31, 2007 to June 30, 2008.

Other Borrowed Funds

         Other borrowings outstanding as of June 30, 2008 and December 31, 2007,
consist of advances (both long-term and short-term) from the Federal Home Loan
Bank ("FHLB"). Table Nine below summarizes these borrowings:

         The maximum amount of short-term borrowings at any month-end during the
first two quarters of 2008 and 2007 was $42,544,000 and $42,384,000,
respectively. The FHLB advances are collateralized by loans and securities
pledged to the FHLB. The following is a breakdown of rates and maturities on
FHLB advances (dollars in thousands):

         The Company has also been issued a total of $3,750,000 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 2008 or 2007 and management does not expect to draw upon these
lines in the future. See the Liquidity section that follows for additional
information on FHLB borrowings.

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 the 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

                                       27
<PAGE>

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, the Bank must meet specific
capital guidelines that involve quantitative measures of assets, liabilities and
certain off-balance-sheet items as calculated under regulatory accounting
practices. The Company's and the Bank's capital amounts and classification are
also subject to qualitative judgments by the regulators about components, risk
weightings and other factors. At June 30, 2008, shareholders' equity was
$61,067,000, representing an increase of $1,094,000 (1.8%) from $59,973,000 at
December 31, 2007. The increase results from the increase in other comprehensive
income, net income for the period, the stock based compensation, and the
proceeds from the exercise of stock options exceeding the stock repurchases and
cash dividends paid to shareholders. The ratio of total risk-based capital to
risk adjusted assets was 11.0% at June 30, 2008 and 10.7% at December 31, 2007.
Tier 1 risk-based capital to risk-adjusted assets was 9.7% at June 30, 2008 and
9.5% at December 31, 2007.

         Table Ten below lists the Company's actual capital ratios at June 30,
2008 and December 31, 2007 as well as the minimum capital ratios for capital
adequacy.

</TABLE>

         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 the Bank met all of their capital
adequacy requirements as of June 30, 2008 and December 31, 2007.

         The Company, through a Board of Director authorized plan, may
repurchase, as conditions warrant, up to 6.5% annually of the Company's common
stock. Repurchases are generally made in the open market at market prices. See
Part II, Item 2, for additional disclosure.

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 significant effect upon the
results of operations of the Company and its subsidiaries during the periods
ended June 30, 2008 and 2007.

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, borrowing arrangements
with the FHLB, payments at maturity of 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
June 30, 2008 and December 31, 2007 were approximately $92,686,000 and
$6,665,000 and $112,633,000 and $7,537,000, respectively. Such loan commitments
relate primarily to revolving lines of credit , 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.

                                       28
<PAGE>

        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. At June 30, 2008, consolidated liquid assets totaled $59.4 million
or 10.2% of total assets compared to $47.1 million or 8.2% of total assets on
December 31, 2007. In addition to liquid assets, the Company maintains
short-term lines of credit in the amount of $52,000,000 with correspondent
banks. At June 30, 2008, the Company had $52,000,000 available under these
credit lines. Additionally, the Bank is a member of the FHLB. At June 30, 2008,
American River Bank could have arranged for up to $123,325,000 in secured
borrowings from the FHLB. These borrowings are secured by pledged mortgage loans
and investment securities. At June 30, 2008, the Company had advances,
borrowings and commitments (including letters of credit) outstanding of
$57,553,000, leaving $65,772,000 available under these FHLB 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 and borrowing capacity 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. These securities are also
available to pledge as collateral for borrowings if the need should arise. The
Bank has established a master repurchase agreement with a correspondent bank to
enable such transactions. The Bank can also pledge securities to borrow from the
FRB 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 the
Bank to service its commitments. The Company expects that the cash dividends
paid by the Bank to the Company will be sufficient to meet this payment
schedule.

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
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 applies
the same credit policies to commitments and letters of credit as it does for
loans included on the consolidated balance sheet. As of June 30, 2008 and
December 31, 2007, commitments to extend credit and standby 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 standby
letters of credit were $99,351,000 and $120,170,000 at June 30, 2008 and
December 31, 2007, respectively. As a percentage of net loans and leases these
off-balance sheet items represent 24.7% and 30.4%, respectively.

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

Other Matters

         Effects of Terrorism. The terrorist actions on September 11, 2001 and
thereafter, as well as, the current military conflicts in Afghanistan and 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. Such 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.

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 simulation modeling indicated below attempts
to estimate changes in the Company's net interest income utilizing a forecast
balance sheet projected from the end of period balances.

         Table Eleven 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.

</TABLE>

         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 reasonable
estimates of interest rate risk.

Item 4.  Controls and Procedures.

         The Company, under the supervision and with the participation of its
management, including the Chief Executive Officer and the Chief Financial
Officer, evaluated the effectiveness of the design and operation of the
Company's "disclosure controls and procedures" (as defined in Rule 13a-15(e) and
15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 30,
2008. Based on that evaluation, the Chief Executive Officer and the Chief
Financial Officer concluded that the Company's disclosure controls and
procedures are effective in timely making known to them material information
relating to the Company and the Company's consolidated subsidiaries required to
be disclosed in the Company's reports filed or submitted under the Exchange Act.

         During the quarter ended June 30, 2008, there have been no changes in
the Company's internal control over financial reporting that have significantly
affected, or are reasonably likely to materially affect, these controls.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings.

         From time to time, the Company and/or its subsidiaries is a party to
claims and legal proceedings arising in the ordinary course of business. The
Company's management is not aware of any significant pending legal proceedings
to which either it or its subsidiaries may be a party or has recently been a
party, which will have a significant adverse effect on the financial condition
or results of operations of the Company or its subsidiaries, taken as a whole.

Item 1A. Risk Factors.

        There have been no significant changes in the risk factors previously
disclosed in the Company's Form 10-K for the period ended December 31, 2007,
filed with the Securities and Exchange Commission on March 6, 2008, although the
overall decline in real estate values in California, and more specifically in
our primary market area, has continued and expanded during 2008. While the
Company has not been materially adversely impacted by this trend to date,
continuing declines in real estate values may have a material adverse effect on
the overall economic conditions in the Company's market area, which could result
in increased loan losses and require a material increase in the allowance for
loan losses and thereby adversely affect the Company's results of operations,
financial condition, future prospects, profitability and stock price.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds.

         On January 16, 2008, the Board of Directors of the Company authorized a
stock repurchase program which allows for the repurchase of up to six and one
half percent (6.5%) annually of the Company's outstanding shares of common
stock. Each year the Company may repurchase up to 6.5% of the shares outstanding
(adjusted for stock splits or stock dividends). The number of shares reported in
column (d) of the table as shares that may be repurchased under the plan
represent shares eligible for the calendar year 2008. The repurchases under this
plan can be made from time to time in the open market as conditions allow and
will be structured to comply with Commission Rule 10b-18. Management reports
monthly to the Board of Directors on the status of the repurchase program. The
Board of Directors has reserved the right to suspend, terminate, modify or
cancel the repurchase programs at any time for any reason. The 6.5% program
announced in 2008, replaced a program announced in 2001 whereby the Company had
the ability to repurchase of up to five percent (5.0%) annually of the Company's
outstanding shares of common stock. The following table lists shares repurchased
during the quarter and the maximum amount available to repurchase under the
repurchase plan as of the dates noted.
