                                       FOR
                         ANNUAL MEETING OF SHAREHOLDERS
                                  May 19, 2005

INTRODUCTION

     This Proxy Statement is furnished in connection with the solicitation of
Proxies for use at the 2005 Annual Meeting of Shareholders (the "Meeting") of
American River Bankshares (the "Company") to be held on Thursday, May 19, 2005
at 5:30 p.m., at the Point West Branch Office, located at 1545 River Park Drive,
Suite 107, Sacramento, California 95815 and at any and all postponements or
adjournments thereof. Only shareholders of record on April 7, 2005 (the "Record
Date") will be entitled to notice of the Meeting and to vote at the Meeting. At
the close of business on the Record Date, the Company had outstanding and
entitled to be voted 5,351,299 shares of the Company's no par value common
stock.

Revocability of Proxies

     A Proxy Card for voting your shares at the Meeting is enclosed. Any
shareholder who executes and delivers such Proxy has the right to and may revoke
it at any time before it is exercised by filing with the Secretary of the
Company an instrument revoking it or a duly executed Proxy bearing a later date.
In addition, a Proxy will be revoked if the shareholder executing such Proxy is
in attendance at the Meeting and such shareholder votes in person. Subject to
such revocation, all shares represented by a properly executed Proxy received in
time for the Meeting will be voted by the Proxyholders in accordance with the
instructions specified on the Proxy Card.

     Unless otherwise directed in the accompanying Proxy Card, the shares
represented by your executed Proxy will be voted "FOR" the nominees for election
of directors named herein and "FOR" the ratification of Perry-Smith LLP as
independent public accountants. If any other business is properly presented at
the Meeting, the Proxy will be voted in accordance with the recommendations of
management.

Solicitation of Proxies

     This solicitation of Proxies is being made by the Board of Directors of the
Company. The expenses of preparing, assembling, printing, and mailing this Proxy
Statement and the materials used in this solicitation of Proxies will be borne
by the Company. It is contemplated that Proxies will be solicited principally
through the use of the mail, but directors, officers, and employees of the
Company may solicit Proxies personally or by telephone, without receiving
special compensation. The Company will reimburse banks, brokerage houses and
other custodians, nominees and fiduciaries for their reasonable expenses in
forwarding these Proxy materials to shareholders whose stock in the Company is
held of record by such entities. In addition, the Company may use the services
of individuals or companies it does not regularly employ in connection with this
solicitation of Proxies, if management determines it is advisable.

Voting Securities

     On any matter submitted to the vote of the shareholders, each holder of
common stock will be entitled to one vote, in person or by Proxy, for each share
of common stock he or she held of record on the books of the Company as of the
Record Date.

     A majority of the shares entitled to vote, represented either in person or
by a properly executed Proxy, will constitute a quorum at the Meeting. If, by
the time scheduled for the Meeting, a quorum of shareholders of the Company is
not present or if a quorum is present but sufficient votes in favor of any of
the proposals have not been received, the Meeting may be held for purposes of
voting on those proposals for which sufficient votes have been received, and the
persons named as proxyholders may propose one or more adjournments of the
Meeting to permit further solicitation of Proxies with respect to any of the
proposals as to which sufficient votes have not been received.

                                       1




     Votes cast by Proxy or in person at the Meeting will be counted by the
Inspectors of Election for the Meeting. The Inspectors will treat abstentions
and "broker non-votes" (shares held by brokers or nominees as to which
instructions have not been received from the beneficial owners or persons
entitled to vote and the broker or nominee does not have discretionary voting
power under applicable rules of the stock exchange or other self-regulatory
organization of which the broker or nominee is a member) as shares that are
present and entitled to vote for purposes of determining the presence of a
quorum. Abstentions and "broker non-votes" will not be counted as shares voted
for purposes of determining the outcome of any matter as may properly come
before the Meeting.

                                 PROPOSAL NO. 1
                              ELECTION OF DIRECTORS

     The Company's Bylaws provide that the number of directors of the Company
shall not be less than eight (8) nor more than fifteen (15) until changed by an
amendment to the Articles of Incorporation or by a Bylaw amending Section 3.2
duly adopted by the vote or written consent of holders of a majority of the
outstanding shares entitled to vote. The exact number of directors shall be
fixed from time to time, within the range specified in the Articles of
Incorporation (i) by a resolution duly adopted by the Board; (ii) by a Bylaw or
amendment thereof duly adopted by the vote of a majority of the shares entitled
to vote represented at a duly held meeting at which a quorum is present, or by
the written consent of the holders of a majority of the outstanding shares
entitled to vote; or (iii) by approval of the shareholders. The exact number of
directors was fixed at nine (9) at a regular meeting of the Board of Directors
held January 21, 2004.

     Director Sam J. Gallina, who has served on the Board of Directors of
American River Bankshares since its inception in 1995 and the Board of American
River Bank since 1986, will be retiring as a Director and as a member of all
committees upon which he currently serves of both American River Bankshares and
American River Bank effective at the completion of his current term as a
director, at the 2005 Annual Meeting of Shareholders. Upon the retirement of Sam
J. Gallina at the end of his current term, the Board of Directors has resolved
to set the number of authorized directors of the Company at eight (8).

     The current classes and allocation of directors are as follows:

             Class I                 Class II                 Class III 
        -------------------       ------------------       ---------------
        Amador S. Bustos          Sam J. Gallina           Charles D. Fite
        Robert J. Fox             Roger J. Taylor          David T. Taber
        William A. Robotham       Michael A. Ziegler       Stephen H. Waks

     As a result of reducing the number of authorized directors to eight (8) the
Board of Directors will be reclassified into two classes as provided in the
Bylaws. Under the previous three class system, the Class II directors would have
their term expire at the 2005 Annual Meeting. Upon the retirement of Mr.
Gallina, the remaining Class II directors are Roger J. Taylor and Michael A.
Zeigler. Thus, the Board of Directors has proposed that Michael A. Ziegler be
elected to a one-year term and that he be made a Class III director and Roger J.
Taylor be elected to a two-year term and that he be made a Class I director
(which will make the existing Class I have four (4) directors and Class III will
have four (4) directors). Messrs. Taylor and Ziegler have agreed to serve a
reduced term to accommodate the reclassification of the Board. Accordingly, the
Class I directors' term will expire at the Annual Meeting in 2007, at which time
all Class I directors will be subject to election for a two-year term. The Class
III directors' term will expire at the Annual Meeting in 2006, at which time
they would also be subject to election for a two-year term. The two classes of
directors will remain in effect until the authorized number of directors is
increased to nine (9) or more directors in the future. In such event, the two
classes would be reclassified into three classes as provided in the Company's
Bylaws.

     Accordingly, Director Ziegler will be elected at the Meeting, to serve for
a one-year term expiring at the 2006 Annual Meeting of Shareholders and be
allocated to Class III and Director Taylor will be elected at the Meeting, to
serve for a two-year term expiring at the 2007 Annual Meeting of Shareholders
and be allocated to Class I. All Proxies will be voted for the election of the
following nominees recommended by the Board of Directors, unless authority to
vote for the election of any or all of the nominees is withheld.

                                       3




     If any nominee should become unable or unwilling to serve as a director,
the proxies will be voted for such substitute nominee as shall be designated by
the Board of Directors. The Board of Directors presently has no knowledge that
any of the nominees will be unable or unwilling to serve.

     The following persons are the nominees of the Board of Directors for
election as directors to be added to Class I and Class III as described above to
serve until their terms expire or until their successors are duly elected and
qualified.

violations of securities laws, convictions in a criminal proceeding (excluding

filed against themselves or an affiliate within the last five years.

Committees of the Board of Directors

     The Audit Committee, whose members are Amador S. Bustos, Robert J. Fox, Sam
J. Gallina (Chairman), and William A. Robotham, oversees the Company's
independent public accountants, analyzes the results of internal and regulatory
examinations and monitors the financial and accounting organization and
reporting. Director Gallina has been designated by the Board of Directors as an
"audit committee financial expert" as defined under rules promulgated by the
Securities and Exchange Commission pursuant to the Sarbanes-Oxley Act of 2002
until his retirement on May 19, 2005. Thereafter, Mr. Fox has been designated
and will serve as the " the audit committee financial expert" and Mr. Robotham
will serve as the Chairman of the Audit Committee. The Audit Committee met five
(5) times in 2004. See the Audit Committee Report on page 18 for additional
information regarding the functions of the Audit Committee. Each member of the
Audit Committee is "independent," as that term is defined under rules
promulgated by the Securities and Exchange Commission pursuant to the
Sarbanes-Oxley Act of 2002, and by applicable Nasdaq Stock Market Rules. In
addition, each other member of the Audit Committee is "financially literate" as
defined under applicable Nasdaq Stock Market Rules.

     The Nominating Committee, whose members are Charles D. Fite, Robert J. Fox,
and Stephen H. Waks, has the responsibility to assist the Board of Directors by
(a) establishing criteria for candidates and identifying, evaluating, and
recommending candidates, including candidates proposed by shareholders, for
election to the Board of Directors, and (b) periodically reviewing and making
recommendations on the composition of the Board of Directors. All members of the
Nominating Committee are "independent," as that term is defined under rules
promulgated by the Securities and Exchange Commission pursuant to the
Sarbanes-Oxley Act of 2002, and applicable Nasdaq Stock Market Rules. Candidates
are selected in accordance with a Nominating Charter. The Nominating Charter
includes a policy for consideration of candidates proposed by shareholders. Any
recommendations by shareholders will be evaluated by the Board of Directors in
the same manner as any other recommendation and in each case in accordance with
the Nominating Charter. Shareholders that desire to recommend candidates for
consideration by the Company's Board of Directors should mail or deliver written
recommendations to the Company addressed as follows: Board of Directors,
American River Bankshares, 1545 River Park Drive, Suite 107 Sacramento,
California 95815. Each recommendation should include biographical information
indicating the background and experience of the candidate that qualifies the
candidate for consideration as a director for evaluation by the Board of
Directors. In addition to minimum standards of independence for non-employee
directors and financial literacy, the Board of Directors considers various other
criteria including the candidate's experience and expertise, financial
resources, ability to devote the time and effort necessary to fulfill the
responsibilities of a director and involvement in community activities in the
market areas served by the Company that may enhance the reputation of the
Company. The Company operates in a highly regulated industry and is subject to
the supervision, regulation and periodic examination by state and federal
banking regulatory authorities including the Board of Governors of the Federal
Reserve System, California Commissioner of Financial Institutions and Federal
Deposit Insurance Corporation. Directors of the Company are subject to certain
rules and regulations and potential liabilities not otherwise applicable to
directors of non-banking organizations. Consequently, evaluation of candidates
by the Company's Board of Directors may include more extensive inquiries into
personal background information including confirmation of the accuracy and
completeness of background information by (a) requiring candidates to complete
questionnaires to elicit information of the type required to be disclosed by the
Company in reports filed with the Securities and Exchange Commission, Nasdaq, or
such state and federal banking regulatory authorities, (b) conducting background
investigations by qualified independent organizations experienced in conducting
criminal and civil investigatory reviews, and (c) such other personal and
financial reviews and analyses as the Board of Directors may deem appropriate in
connection with the consideration of candidates. Shareholders who wish to
nominate a candidate for election to the Company's Board of Directors, as
opposed to recommending a potential nominee for consideration by the Board of
Directors, are required to comply with the advance notice and any other
requirements of the Company's bylaws, applicable laws and regulations. The Board
of Directors may elect to use third parties in the future to identify or
evaluate candidates for consideration by the Board of Directors. The Nominating
Charter adopted by the Board of Directors is attached to this Proxy Statement as
Appendix A. The Nominating Committee recommended the slate of Nominees for
Election described on pages 3 and 4.

     The Compensation Committee, whose members include Charles D. Fite
(Chairman), Sam J. Gallina, Roger J. Taylor, D.D.S., and Stephen H. Waks,
oversees the performance and reviews the compensation of the executive officers
of the Company and American River Bank. The Compensation Committee met nine (9)
times during 2004. See the Compensation Committee Report on page 13 for

                                       5


additional information regarding the functions of the Compensation Committee.
The Board has determined that all members of the Compensation Committee are
"independent," as that term is defined by applicable Nasdaq Stock Market Rules.
In December 2004, Amador S. Bustos, Robert J. Fox, and William Robotham were
added to the Compensation Committee and Sam J. Gallina and Stephen H. Waks left
the committee.

     The Finance and Capital Committee, whose members include William A.
Robotham, Roger J. Taylor, D.D.S., Stephen H. Waks (Chairman), and Michael A.
Ziegler, has the responsibility to (a) oversee asset liability management and
the investment portfolio including recommending to the full Board of Directors
the annual investment strategy; (b) recommend to the full Board of Directors the
annual operating budget for the Company; and (c) review premises leases for
recommendation to the full Board of Directors. The Finance and Capital Committee
met five (5) times during 2004.

     The Executive Committee, whose members include Charles D. Fite (Chairman),
Sam J. Gallina, David T. Taber, Roger J. Taylor, D.D.S., and Stephen H. Waks
(who joined in March 2004) oversees long range planning, formulates and
recommends broad policy positions for the full Board of Directors to consider
and is responsible for evaluating and recommending to the full Board of
Directors matters pertaining to mergers and acquisitions. The Executive
Committee met nine (9) times during 2004.

     The Loan Committee has the responsibility for establishing loan policy,
approving loans which exceed certain dollar limits and reviewing the outside
loan review firm's examinations of the loan portfolios. American River Bank's
Loan Committee includes Charles D. Fite, Robert J. Fox, Sam J. Gallina, Roger J.
Taylor, D.D.S. (Chairman), Stephen H. Waks, and Philip A. Wright. American River
Bank's Loan Committee met twenty-nine (29) times during 2004.

     During 2004, the Company's Board of Directors held twelve (12) regular
meetings and four (4) special meetings. In addition, the Company's Board of
Directors held four (4) "executive sessions" which only the non-employee
directors attended, each of whom is "independent" as defined under rules
promulgated by the Securities and Exchange Commission pursuant to the
Sarbanes-Oxley Act of 2002, and applicable Nasdaq Stock Market Rules. All
directors attended at least 75% of the aggregate of the total number of meetings
of the Board of Directors and the number of meetings of the committees on which
they served.

     A majority of the members of the Board of Directors, each of whom is
"independent" as defined under applicable rules promulgated by the Securities
and Exchange Commission pursuant to the Sarbanes-Oxley Act of 2002, and
applicable Nasdaq Stock Market Rules, has established procedures for receipt and
delivery of shareholder communications addressed to the Board of Directors. Any
such shareholder communications, including communications by employees of the
Company solely in their capacity as shareholders, should be mailed or delivered
to the Company addressed as follows: Board of Directors, American River
Bankshares, 1545 River Park Drive, Suite 107 Sacramento, California 95815.

     The Company requires members of its Board of Directors to attend the
Company's annual meeting of shareholders each year. With the exception of Doctor
Roger J. Taylor, D.D.S., all the directors attended the Company's annual meeting
of shareholders held in 2004.

Compensation of Directors

     The fees paid to non-employee directors of American River Bankshares during
2004 included a retainer of $350 per month, a base fee of $250 per month for
attendance at board meetings, and a fee of $150 per month for attendance at
committee meetings, other than the Directors Loan Committee of American River
Bank whose outside director members received a fee of $250 for each meeting
attended. Outside director members of the Executive Committee received an
additional retainer fee of $150 per month. In addition to the fees received as
non-employee directors in connection with the meetings and matters described
above, the Chairman of the Board of Directors also received a retainer fee of
$250 per month, and the Chairman of the Audit Committee and the Chairman of
American River Bank's Directors Loan Committee also received a retainer fee of
$150 per month. The Chairman of the Finance and Capital Committee also received
a retainer fee of $50 per month. In 2004, the total amount of fees paid by
American River Bankshares and American River Bank to all directors as a group
was $129,900.

     The Company has a 1995 Stock Option Plan (the "1995 Plan") and a 2000 Stock
Option Plan (the "2000 Plan") pursuant to which non-qualified stock options have
been granted. Stock options granted under the 1995 are fully vested and are
exercisable until their expiration; however, no new options will be granted
under the 1995 Plan. As of the Record Date, all of the stock options granted to

                                       6


the current directors under the 1995 Plan have been exercised except 15,829
shares granted in 1995 to Roger J. Taylor, D.D.S. On April 21, 2004, directors
that served the Company for the entire year of 2003 (Charles D. Fite, Sam J.
Gallina, Roger J. Taylor, D.D.S., Stephen H. Waks, and Michael A. Ziegler) were
granted a nonstatutory stock option under the 2000 Plan to purchase 4,365 shares
of American River Bankshares common stock at $21.42 per share (converted to
4,583 shares at $20.40 as adjusted for the 5% stock dividend declared in
December 2004). On March 19, 2003, Directors Fite, Gallina, Taylor, and Waks
were granted a nonstatutory stock option to purchase 1,940 shares of American
River Bankshares common stock at $22.34 per share (converted to 3,055 shares at
$14.186 as adjusted for a 3-for-2 stock split and a 5% stock dividend). On May
21, 2003, Director Ziegler was granted a nonstatutory stock option to purchase
485 shares of American River Bankshares common stock at $24.22 per share
(converted to 763 shares at $15.383 as adjusted for a 3-for-2 stock split and a
5% stock dividend).

     On June 18, 1997, the Board of Directors approved a Gross-Up Plan (the
"Plan") to compensate for the tax effects of the exercise of nonstatutory stock
options. The Plan named Directors Charles D. Fite, Sam J. Gallina, Roger J.
Taylor, D.D.S., and Stephen H. Waks as participants and applies only to those
options granted on August 25, 1995. As of the Record Date, all stock options
eligible under this Plan have been exercised except 15,829 stock options granted
to Roger J. Taylor, D.D.S. The Plan encourages participating optionees to retain
shares acquired through the exercise of nonstatutory stock options by American
River Bankshares paying to the participating optionee an amount equal to the
taxable income resulting from an exercise of a nonstatutory stock option
multiplied by American River Bankshares' effective tax rate, subject to the
optionee's agreement to hold the shares acquired for a minimum of one (1) year.
In the event that the shares acquired upon exercise are not held for at least
one year from the date of acquisition, the optionee is required to reimburse the
amount paid to the optionee under the Plan. During 2004, Director Fite executed
an agreement in return for payment of $188,613.

     Effective December 20, 2001, a Deferred Fee Plan was established for the
purpose of providing the directors an opportunity to defer director fees.
Participating directors may elect to defer a portion, up to 100%, of their
monthly director fees. American River Bankshares bears the administration costs
and pays interest on the deferred balances at a rate equal to the five-year U.S.
Treasury Bond plus 4.0%, but does not, otherwise, make contributions to the
Plan. During 2004, two directors participated in the Plan and deferred $10,550.

     In January 2003, the Board of Directors approved a Directors Retirement
Plan and in June 2004 this plan was replaced with a Director Emeritus Program,
whereby each director, upon full retirement from the Company's or an affiliate's
Board of Directors, is entitled to receive installment payments over a 24 month
period following retirement which are equal to the total Board of Director and
Committee fees received by a director for such service during the two full
calendar years prior to retirement. The Director Emeritus Program contains a
ten-year vesting component. A director vests 10% for each year of service on the
Board of Directors of the Company or an affiliate Board of Directors. During
2004, five former directors participated in this Emeritus Program and received
payments totaling $39,617.

(1)  Amounts shown include cash compensation earned and received by executive
     officers as well as amounts earned but deferred at the election of those
     officers under the 401(k) Plan and the Deferred Compensation Plan.

                                       8


(2)  Amounts indicated as bonus payments are listed in the year paid. The
     amounts listed as paid in 2004 were all earned in 2003. Additional amounts
     accrued in 2004 and paid in 2005 were $120,946 to Mr. Taber; $37,795 to Mr.
     Derenzo; $39,678 to Mr. Patton; $31,532 to Mr. Byrne; $28,189 to Mr.
     Bender; and $32,587 to Mr. Tow.
(3)  No executive officer received perquisites or other personal benefits in
     excess of the lesser of $50,000 or 10% of each such officer's total annual
     salary and bonus during 2004, 2003, and 2002.
(4)  Represents the number of shares granted in the year indicated, as adjusted
     for stock splits and stock dividends. The Company had a 1995 Stock Option
     Plan (the "1995 Plan") pursuant to which options could be granted to
     directors and key, full-time salaried officers and employees of the Company
     and American River Bank. The 1995 Plan was replaced with the Company's 2000
     Stock Option Plan (the "2000 Plan"). Options granted under the 1995 Plan
     were either incentive options or nonstatutory options. Options granted
     under the 1995 Plan became exercisable in accordance with a vesting
     schedule established at the time of grant. Vesting could not extend beyond
     ten years from the date of grant. Upon a change in control of the Company,
     all outstanding options under the 1995 Plan will become fully vested and
     exercisable. Options granted under the 1995 Plan are adjusted to protect
     against dilution in the event of certain changes in the Company's
     capitalization, including stock splits and stock dividends. The 2000 Plan
     is substantially similar to the 1995 Plan regarding provisions related to
     option grants, vesting, and dilution. All options granted to the named
     executive officers have an exercise price equal to the fair market value of
     the common stock on the date of grant.
(5)  Amounts shown for each named executive officer include 401(k) matching
     contributions, the use of an automobile owned by the Company, earned but
     unpaid interest on amounts deferred under the Company's Deferred
     Compensation Plan, excess life insurance premiums paid by the Company, and
     amounts accrued pursuant to post-retirement agreements as described below.
(6)  North Coast Bank and Bank of Amador are divisions of American River Bank.
(7)  Mr. Standing joined the Company in December 2004 (see Employment Contracts
     and Termination of Employment and Change in Control Agreements below).

Stock Options

     The following table describes stock options that were granted pursuant to
the Company's 2000 Stock Option Plan (the "2000 Stock Option Plan") to the
Company's executive officers in the fiscal year ended December 31, 2004.
Shareholders approved the 2000 Stock Option Plan on September 21, 2000. All of
the grants were made on April 21, 2004 based on achievement of 2003 corporate
and personal performance objectives.

(1)  All options are incentive stock options, which vest ratably over a
     five-year period commencing one year after the grant date. The terms of all
     of the Company's stock option plans provide that options may become
     exercisable in full in the event of a change of control as defined in the
     2000 Stock Option Plan.
(2)  The Black-Scholes option-pricing model is used to determine grant date
     present value. To derive the per share option value of $4.92, the
     assumptions used include a risk-free rate equal to the seven-year
     interpolated treasury yield of 4.01%, volatility of 22.0%, and a seven-year
     maturity.

     The following table sets forth the number of shares of common stock
acquired by each of the named executive officers upon the exercise of stock
options during fiscal year 2004, the net value realized upon exercise, the
number of shares of common stock represented by outstanding stock options held
by each of the named executive officers as of December 31, 2004, the value of
such options based on the closing price of the Company's common stock, and
certain information concerning unexercised options under the 1995 and 2000 Stock
Option Plans.

Employment Contracts and Termination of Employment and Change in Control
Arrangements

     In August 2003, the Company entered into an employment agreement with David
T. Taber. The agreement provides for an original term of two years subject to
automatic one-year extensions thereafter unless terminated in accordance with
the terms of the agreement. The agreement provides for a base salary which is
disclosed in the Summary Compensation Table on page 8. The base salary under the
agreement is reviewed annually and is subject to adjustment at the discretion of
the Board of Directors. Additionally, the agreement provides for, among other
things (i) an annual incentive bonus based upon the Company's achievement of
certain profitability, growth and asset quality standards as set forth in the
agreement; (ii) in the event of disability, payment of base salary reduced by
the amounts received from state disability insurance or workers' compensation or
other similar insurance benefits through policies provided by the Company; (iii)
stock option grants in the discretion of the Board of Directors under the
Company's stock option plan; (iv) four weeks annual paid vacation leave; (v) use
of an automobile; and (vi) reimbursement for ordinary and necessary expenses
incurred in connection with employment. The agreement may be terminated with or
without cause, but if the agreement is terminated without cause due to the
occurrence of circumstances that make it impossible or impractical for the
Company to conduct or continue its business, the loss by the Company of its
legal capacity to contract or the Company's breach of the terms of the
agreement, the employee is entitled to receive severance compensation equal to
six months of the existing base salary plus any incentive bonus due. The
agreement further provides that in the event of a "change in control" as defined
therein and within a period of two years following consummation of such change
in control (i) the employee's employment is terminated; or (ii) any adverse
change occurs in the nature and scope of the employee's salary or benefits; or
(iii) any event occurs which reasonably constitutes a constructive termination
of employment, by resignation or otherwise, then the employee will be entitled
to receive severance compensation in an amount equal to eighteen (18) months of
the employee's annual base salary, less applicable withholding deductions (in
addition to salary, incentive compensation, or other payments, if any, due the
employee).

     In December 2004, the Company's subsidiary, American River Bank, entered
into an employment agreement with Larry D. Standing. The agreement provides for
an original term of two years subject to automatic one-year extensions
thereafter unless terminated in accordance with the terms of the agreement. The
agreement provides for a base salary of $150,000. The amount earned in 2004 is
disclosed in the Summary Compensation Table on page 8. The base salary under the
agreement is reviewed annually and is subject to adjustment at the discretion of
the Board of Directors. Additionally, the agreement provides for, among other
things (i) an annual incentive bonus based upon the Company's achievement of
certain profitability, growth and asset quality standards as set forth in the
agreement; (ii) in the event of disability, payment of base salary reduced by

                                       10


the amounts received from state disability insurance or workers' compensation or
other similar insurance benefits through policies provided by the Company; (iii)
stock option grants in the discretion of the Board of Directors under the
Company's stock option plan; (iv) four weeks annual paid vacation leave; (v) use
of an automobile; and (vi) reimbursement for ordinary and necessary expenses
incurred in connection with employment. The agreement may be terminated with or
without cause, but if the agreement is terminated without cause due to the
occurrence of circumstances that make it impossible or impractical for the
Company to conduct or continue its business, the loss by the Company of its
legal capacity to contract or the Company's breach of the terms of the
agreement, the employee is entitled to receive severance compensation equal to
six months of the existing base salary plus any incentive bonus due. The
agreement further provides that in the event of a "change in control" as defined
therein and within a period of two years following consummation of such change
in control (i) the employee's employment is terminated; or (ii) any adverse
change occurs in the nature and scope of the employee's salary or benefits; or
(iii) any event occurs which reasonably constitutes a constructive termination
of employment, by resignation or otherwise, then the employee will be entitled
to receive severance compensation in an amount equal to eighteen (18) months of
the employee's annual base salary, less applicable withholding deductions (in
addition to salary, incentive compensation, or other payments, if any, due the
employee).

     On March 18, 1998, American River Bank adopted the American River Bank
Employee Severance Policy. The Policy allows for certain named employees to
receive severance payments equal to six times their monthly base pay should
these named employees be terminated within one year of a "change in control."
The Board of Directors has designated executive officers Mitchell A. Derenzo,
Kevin B. Bender, Gregory N. Patton, Raymond F. Byrne, and Douglas E. Tow to be
covered under the Policy.

     Recognizing the importance of building and retaining a competent management
team, additional agreements were entered into to provide post-retirement
benefits to Messrs. Taber, Derenzo, and Tow. The terms of the agreements include
the amounts each employee will receive upon the occurrence of certain specified
events, including formal retirement on or after a specified age. The agreements
generally provide for annual retirement benefit payments of One Hundred Thousand
Dollars ($100,000) to Mr. Taber and Fifty Thousand Dollars ($50,000) each to Mr.
Derenzo, and Mr. Tow. The annual retirement benefit amount is payable in equal
monthly installments over a fifteen (15) year period. In the event of an
employee's death, all remaining amounts due are anticipated to be paid to the
employee's designated beneficiary over the remaining payout period. Other events
which may alter when payment of the annual retirement benefit is to begin, or
the amount which is to be paid, include: (a) disability prior to retirement in
which case the employee shall be entitled to a lesser benefit payment amount
based upon the length of employment; and (b) termination following a "change of
control," in which case the employee is entitled to receive the annual benefit
payment in equal monthly installments for fifteen (15) years beginning in the
month following the termination or "change of control" equal to Sixty-Four
Thousand Nine Hundred and Seventy Dollars ($64,970) for Mr. Taber and Thirty-Two
Thousand Four Hundred and Eighty-Five Dollars ($32,485) each for Mr. Derenzo,
and Mr. Tow. The Company purchased insurance policies in connection with these
agreements on the lives of Messrs. Taber, Derenzo, and Tow paying the premiums
for these insurance policies with a lump-sum premium payment of approximately
$954,100.

Deferred Compensation Plans

     Effective May 1, 1998, the American River Bank Deferred Compensation Plan
was established for the purpose of providing certain highly compensated
individuals, which includes the executive officers, an opportunity to defer
compensation. Participants, who are selected by a committee designated by the
Board of Directors, may elect to defer annually a minimum of $5,000 or a maximum
of eighty percent of their base salary and all of their cash bonus. American
River Bank bears all administration costs, but does not make contributions to
the plan. Effective December 20, 2000, the Deferred Compensation Plan was
renamed the American River Bankshares Deferred Compensation Plan and beginning
January 1, 2001, the Company now bears the administration costs for participants
that are employed by the Company and American River Bank bears the costs for
participants that are employed by American River Bank. The Deferred Compensation
Plan requires the Company and American River Bank to pay interest on the
deferred balances at a rate equal to the five-year U.S. Treasury Bond plus 4.0%.
In addition, the executive officers are eligible to participate in the Company's
401(k) Plan. Under the 401(k) Plan, the Company matches salary deferrals at a
rate of 100% of the participant's contributions up to 3% of such participant's
annual compensations plus 50% of the next 2% of annual compensation.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The compensation of the executive officers of American River Bankshares is
reviewed and approved annually by the Board of Directors on recommendation by
the Compensation Committee. During 2004, Charles D. Fite (Chairman), Sam J.
Gallina, Roger J. Taylor, D.D.S., and Stephen H. Waks served as members of the
Compensation Committee. Each such member of the Committee is "independent" as
defined under applicable rules promulgated by the Securities and Exchange
Commission pursuant to the Sarbanes-Oxley Act of 2002, and applicable Nasdaq
Stock Market Rules. Mr. Taber was not present during the Compensation Committee
voting or deliberations regarding his compensation as required by applicable
Nasdaq Stock Market Rules. David T. Taber, Mitchell A. Derenzo, Raymond F.
Byrne, Gregory N. Patton, Larry D. Standing, Kevin B. Bender, and Douglas E. Tow
served as executive officers of American River Bankshares during 2004 in the
capacities reflected in the Summary Compensation Table.

     The Compensation Committee's philosophy is that compensation should be
designed to reflect the value created for shareholders while supporting American
River Bankshares' strategic goals. The Compensation Committee reviews annually
the compensation of the executive officers to insure that American River
Bankshares' compensation programs are related to financial performance and
consistent generally with employers of comparable size in the industry. Annual
compensation for American River Bankshares' executive officers includes the
following components:

     1)    Base salary is related to the individual executive officer's level
of responsibility and comparison with comparable employers in the industry.

     2)    Executive officers are eligible to participate in the American River
Bankshares Incentive Compensation Plan (the "Incentive Plan"). The Incentive
Plan outlines minimum financial performance standards which include performance,
growth, efficiency and asset quality minimums which must be achieved prior to
any payout. If the performance standards are met, the pool amount available for
payment to all employees of the Company is set at a predetermined rate by the
Compensation Committee. The incentive pool for 2004 was set at 14.36% of net
income prior to incentive accruals and adjusted for taxes. The actual amounts
accrued in 2004 to be paid in 2005 represented 14.36% of net income prior to
incentive accruals and adjusted for taxes. The incentive pool also includes
401(k) matching funds.

     3)    Stock option grants are intended to increase the executive officers'
interest in American River Bankshares' long-term success and link interests of
the executive officer with those of shareholders as measured by American River
Bankshares' share price. Stock options are granted at the discretion of the
Board of Directors and at the prevailing market value of American River
Bankshares common stock. Consequently, the value of the options is directly
connected to the increase in value of American River Bankshares' stock price.
See the Summary Compensation Table, Option/SAR Grant Table, and Option/SAR
Exercise Table, and notes thereto for a further description of stocks options.

     4)    American River Bankshares matches salary deferred by employees
participating in its 401(k) Plan at a rate equal to 100% of the participant's
contribution up to 3% of such participant's annual compensation plus 50% of the
next 2% of annual compensation. Executive officers are eligible to participate
in the 401(k) plan. See the Summary Compensation Table for further 401(k) plan
information.

TRANSACTIONS WITH MANAGEMENT AND OTHERS

     There have been no transactions, or series of similar transactions, during
2004, or any currently proposed transaction, or series of similar transactions,
to which American River Bankshares or American River Bank was or is to be a
party, in which the amount involved exceeded or will exceed $60,000 and in which
any director or executive officer of American River Bankshares or American River
Bank, any shareholder owning of record or beneficially 5% or more of American
River Bankshares common stock, or any member of the immediate family of any of
the foregoing persons, had, or will have, a direct or indirect material
interest, except as follows:

     American River Bank leases premises at 9750 Business Park Drive,
Sacramento, California, from Bradshaw Plaza Group, which is owned in part by
Charles D. Fite, a director of American River Bankshares, in addition to
ownership by other family members. The lease term is 7 years and expires on
November 30, 2006, subject to extension for one five-year option term. The
premises consist of 4,590 square feet on the ground floor. The current monthly
rent is $7,900. The approximate aggregate rental payments for the period from
January 1, 2005 through the lease term expiring on November 30, 2006 will be
$179,500. If the five-year option is exercised, the approximate aggregate rental
payments for the option term will be $474,000.

Certain Business Relationships

     There were no business relationships during 2004 of the type requiring
disclosure under Item 404(b) of Regulation S-K.

Indebtedness of Management

     American River Bankshares, through American River Bank, has had, and
expects in the future to have banking transactions in the ordinary course of its
business with many of American River Bankshares' directors and officers and
their associates, including transactions with corporations of which such persons
are directors, officers or controlling shareholders, on substantially the same
terms (including interest rates and collateral) as those prevailing for
comparable transactions with others. Management believes that in 2004 such
transactions comprising loans did not involve more than the normal risk of
collectability or present other unfavorable features. Loans to executive
officers of American River Bankshares and American River Bank are subject to
limitations as to amount and purposes prescribed in part by the Federal Reserve
Act, as amended, and the regulations of the Federal Deposit Insurance
Corporation.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors, executive officers and any persons beneficially owning
ten percent or more of the Company's common stock to timely file initial reports
of ownership and reports of changes in that ownership with the Securities and
Exchange Commission. Such persons are required by Securities and Exchange
Commission regulation to send copies of such reports to the Company. To the
Company's knowledge, based solely on a review of the copies of such reports
furnished to the Company and written representations that no other reports were
required, during the fiscal year ended December 31, 2004, the Company believes
all such filing requirements applicable to its directors, executive officers and
ten percent shareholders were met, except for a Form 3 filed late by American
River Bank Director Philip A. Wright and a Form 3 filed late by executive
officer Kevin B. Bender.

CODE OF ETHICS

     The Company has adopted a Code of Ethics that complies with the rules
promulgated by the Securities and Exchange Commission pursuant to the
Sarbanes-Oxley Act of 2002 and applicable Nasdaq Stock Market Rules. The Code of
Ethics requires that the Company's directors, officers (including the principal
executive, financial and accounting officers, or controller and persons
performing similar functions) and employees conduct business in accordance with
the highest ethical standards and in compliance with all laws, rules and
regulations applicable to the Company. The Code of Ethics is intended to
supplement the provisions of any other personnel policies of the Company or
codes of conduct which may establish additional standards of ethical behavior
applicable to the Company's directors, officers and employees.

                                       15


     The Code of Ethics was filed as Exhibit 14.1 to the Company's 2003 Annual
Report on Form 10-K and may be accessed through the Company's website by
following the instructions for accessing reports filed with the Securities and
Exchange Commission hereafter in this Proxy Statement under the heading

                                 PROPOSAL NO. 2
          RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

     The accounting firm of Perry-Smith LLP, certified public accountants,
served the Company as its independent public accountant and auditor for the 2004
fiscal year at the direction of the Audit Committee and the Board of Directors
of the Company. Perry-Smith LLP has no interests, financial or otherwise, in the
Company. The services rendered by Perry-Smith LLP during the 2004 fiscal year
were audit services, consultation in connection with various accounting matters,
and preparation of the Company's income tax returns.

     The table below summarizes the services rendered to the Company by
Perry-Smith LLP during and for the 2004 and 2003 fiscal years.

                                               2004           2003     
                                            ----------     ----------
         Audit Fees (1)                     $   98,000     $   81,960
         Audit-Related Fees (2)             $    1,600     $    7,415
         Tax Fees (3)                       $   26,995     $   10,000
         All Other Fees (4)                 $       --     $       --
         Total Accounting Fees              $  126,595     $   99,375

(1)  Audit fees consisted of services rendered by Perry-Smith LLP for the audit
     of the Company's consolidated financial statements included in the annual
     report on Form 10-K and for reviews of the financial statements included in
     the Company's quarterly reports on Form 10-Q for fiscal years 2004 and
     2003, including auditing of the Bank of Amador acquisition.
(2)  Audit-related fees represent fees for professional services such as
     technical accounting, consulting, and research.
(3)  Tax fees consisted principally of services rendered by Perry-Smith LLP for
     assistance relating to tax compliance and reporting for fiscal years 2004
     and 2003.
(4)  All other fees consist primarily of consulting services.

     The Audit Committee approved each professional service rendered by
Perry-Smith LLP during the 2004 and 2003 fiscal years and considered whether the
provision of such services is compatible with Perry-Smith LLP maintaining its
independence. The approval of such professional services included pre-approval
of all audit and permissible non-audit services provided by Perry-Smith LLP.
These services included audit, tax and other services described above. The Audit
Committee Charter attached as Appendix B includes a policy of pre-approval of
all services provided by the Company's independent public accountants. The Audit
Committee approved one hundred percent (100%) of all such professional services
provided by Perry-Smith LLP during the 2004 and 2003 fiscal years. It is
anticipated that one or more representatives of Perry-Smith LLP will be present
at the Meeting and will be able to make a statement if they so desire and answer
appropriate questions.

     The Board of Directors has selected Perry-Smith LLP to serve as the
Company's independent public accountants for the year 2005 and recommends that
shareholders vote "FOR" the ratification of the appointment of Perry-Smith LLP.
The ratification of the appointment of Perry-Smith LLP as the Company's
independent public accountants requires approval of a majority of the total
number of shares voting at the Meeting. In the event such appointment is not
ratified, the adverse vote will be deemed to be an indication to the Board of
Directors that it should consider selecting other independent public accountants
for 2005. Because of the difficulty and expense of making any substitution of
accounting firms after the beginning of the current year, it is the intention of
the Board of Directors that the appointment of Perry-Smith LLP for the year 2005
will remain in effect; however, the Board of Directors also retains the power to
appoint another independent public accounting firm to replace the accountants
ratified by the shareholders in the event the Board of Directors determines that
the interests of the Company and its shareholders require such a change.

AUDIT COMMITTEE REPORT

NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH IN ANY OF THE COMPANY'S
PREVIOUS OR FUTURE FILINGS UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES
EXCHANGE ACT OF 1934 THAT MIGHT INCORPORATE THIS PROXY STATEMENT OR FUTURE
FILINGS WITH THE SECURITIES AND EXCHANGE COMMISSION, IN WHOLE OR IN PART, THE
FOLLOWING REPORT SHALL NOT BE DEEMED TO BE INCORPORATED BY REFERENCE INTO ANY
SUCH FILING.

     The Audit Committee consists of the following members of the Company's
Board of Directors: Amador A. Bustos, Sam J. Gallina, (Chairman and Audit
Committee Financial Expert), Robert J. Fox, and William A. Robotham. Each such
member of the Committee is "independent" as defined under applicable rules
promulgated by the Securities and Exchange Commission pursuant to the
Sarbanes-Oxley Act of 2002, and applicable Nasdaq Stock Market Rules.

     The Committee operates under a written charter adopted by the Board of
Directors which, among other matters, delineates the responsibilities of the
Committee. The Committee's responsibilities include responsibility for the
appointment, compensation, retention and oversight of the work of the Company's
independent public accountants engaged (including resolution of disagreements
between management and the independent public accountants regarding financial
reporting) for the purpose of preparing or issuing an audit report or performing
other audit, review or attest services for the Company. The Company's
independent public accountants report directly to the Committee. The written
charter adopted by the Board of Directors is attached to this Proxy Statement as
Appendix B.

     The Committee has reviewed and discussed the audited financial statements
of the Company for the fiscal year ended December 31, 2004 with management and
Perry-Smith LLP, the Company's independent public accountants. The Committee has
also discussed with Perry-Smith LLP, the matters required to be discussed by
Statement on Auditing Standards No. 61 (Codification of Statements on Auditing
Standards) as may be modified or supplemented. The Committee has also received
the letter from Perry-Smith LLP required by Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees) as may be
modified or supplemented, and the Committee has discussed the independence of
Perry-Smith LLP with that firm.

     Based on the Committee's review and discussions noted above, the Committee
recommended to the Board of Directors that the Company's audited financial
statements be included in the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 2004 for filing with the Securities and Exchange
Commission.
