                        NOTES TO THE UNAUDITED PRO FORMA
              COMBINED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Unaudited Pro Forma Combined Condensed Consolidated Balance Sheet ("Pro
Forma Balance Sheet") combines the historical Balance Sheets of American River
Bankshares ("AMRBK") and Bank of Amador ("BNKA") giving effect to the
consummation of the merger as of September 30, 2004. The Unaudited Pro Forma
Combined Condensed Consolidated Statements of Income ("Pro Forma Income
Statements") for the nine months ended September 30, 2004 and the year ended
December 31, 2003 give effect to the consummation of the merger as if such
transaction had become effective at the beginning of each respective period. The
merger will be accounted for using the purchase method of accounting and giving
effect to the related pro forma adjustments described in the accompanying notes
to the Unaudited Pro Forma Combined Condensed Consolidated Financial Statements
("Pro Forma Financial Statements").

The Pro Forma Financial Statements included herein are presented for information
purposes only. They include various estimates and may not necessarily be
indicative of the financial position or results of operations that would have
occurred if the merger had been consummated on the date or at the beginning of
the periods indicated or which may be obtained in the future. These pro forma
financial statements and accompanying notes should be read together with the
historical financial statements, including the notes thereto, of AMRBK that have
been presented in prior filings with the SEC and of BNKA, which are included and
incorporated by reference herein.

We anticipate that the merger will provide the combined company with financial
benefits including cost savings and enhanced revenue opportunities. The pro
forma information, while helpful in illustrating the financial characteristics
of the combined company under one set of assumptions, does not reflect benefits
of expected cost savings or revenue opportunities and, accordingly, does not
attempt to predict or suggest future operating results. It also does not
necessarily reflect what the historical results of the combined company would
have been had the companies been combined during these periods.

Note (1) - Basis of Presentation

The merger with BNKA was completed on December 3, 2004 through the exchange of
850,627 shares of AMRBK's common stock valued at approximately $20,054,000 and
cash of approximately $10,763,000 for all of the outstanding common shares of
AMRBK. The shares and the cash exchanged assumes no BNKA shareholders exercise
their dissenters' rights and assumes no holdback of cash as set forth in the
merger agreement.

Management of AMRBK determined the estimated fair value adjustments for assets
acquired and liabilities assumed by AMRBK with the assistance of certain
investment banking and consulting firms. Based upon a preliminary analysis, it
is anticipated that book value will be a reasonable approximation of fair value
with the exception of the valuation of BNKAs investment securities portfolio.
The resulting core deposit intangible is being amortized into income over eight
years.

Deferred tax assets and liabilities were recorded to reflect the tax
consequences associated with differences between the tax basis and book basis of
the assets acquired and liabilities assumed, using a tax rate of 40%.

Certain reclassifications have been made to BNKA's historical financial
information in order to conform to AMRBK's financial information.

Note (2) - Pro Forma Adjustments

Summarized below are the pro forma adjustments necessary to reflect the merger
based on the purchase method of accounting:

       (a)    Cash consideration paid to Bank of Amador shareholders assuming no
              holdback of cash at the closing, in addition to cash paid for
              merger related costs.
       (b)    Adjustments to reflect the fair value of the assets and
              liabilities are not considered material and are omitted for this
              presentation.

       (c)    Goodwill of $16.0 million and core deposit intangible of $2.8

              assumes no BNKA shareholders exercised their dissenters' rights:
