PROXY STATEMENT

OF

BANK OF MARIN BANCORP

504 Redwood Boulevard, Suite 100

Novato, California 94947

These proxy materials are furnished in connection with the solicitation by management of Bank of Marin Bancorp (the “Company”), of proxies for use at the Annual Meeting of Shareholders of the Company to be held on Tuesday, May 12, 2009, at 6:00 p.m. at the Marin Showcase Theatre at the Marin Center, 10 Avenue of the Flags, San Rafael, California, and at any adjournment thereof.

PURPOSE OF MEETING

The matters to be considered and voted upon at the meeting will be:

GENERAL PROXY STATEMENT INFORMATION

Bank of Marin Bancorp, a corporation existing and organized under the laws of the State of California, is authorized to issue up to 15,000,000 shares of common stock and 5,000,000 shares of preferred stock. As of March 17, 2009, two classes of stock were issued consisting of shares of common stock and shares of the Company’s Series B Cumulative Perpetual Preferred Stock. On March 31, 2009, all shares of the Company’s Series B Preferred were repurchased by the Company. All of the shares are voting shares and are entitled to vote at the Annual Meeting. Only those common shareholders of record as of March 17, 2009 (the “Record Date”) will be entitled to notice of, and to vote at, the meeting. On that date, 5,154,151 shares of common stock were outstanding. The determination of shareholders entitled to vote at the meeting and the number of votes to which they are entitled was made on the basis of the Company’s records as of the Record Date. The presence in person or by proxy (including web and telephone voting) of a majority of the outstanding shares of stock entitled to vote at the Annual Meeting will constitute a quorum for the purpose of transacting business at the meeting. Abstentions, shares as to which voting authority has been withheld from any nominee and “broker non-votes” (as defined below), will be counted for purposes of determining the presence or absence of a quorum.

A broker or nominee holding shares for beneficial owners may vote on certain matters at the meeting pursuant to discretionary authority or instructions from the beneficial owners, but with respect to other matters for which the broker or nominee may not have received instructions from the beneficial owners and may not have discretionary voting power under the applicable rule of the New York Stock Exchange or other self-regulatory organizations to which the broker or nominee is a member, the shares held by the broker or nominee may not be voted. Such unvoted shares are called “broker non-votes.” The rules of the New York Stock Exchange and other self-regulatory organizations generally permit a broker or nominee, in the absence of instructions, to deliver a proxy to vote for directors in an uncontested election. Consequently, shares held by a broker or nominee will not constitute “broker non-votes” regarding that proposal.

Revocability of Proxies

A proxy for use at the meeting is enclosed. Any shareholder who executes and delivers such proxy has the right to revoke it at any time before it is exercised by filing with the Corporate Secretary of the Company an instrument revoking it or by filing a duly executed proxy bearing a later date. In addition, the powers of the proxy

2

Table of Contents

holder will be revoked if the person executing the proxy is present at the meeting and elects to vote in person by advising the chairman of the meeting of such election. Subject to such revocation or suspension, all shares represented by a properly executed proxy received in time for the meeting will be voted by the proxy holders in accordance with the instructions on the proxy.

IF NO INSTRUCTION IS SPECIFIED WITH REGARD TO A MATTER TO BE ACTED UPON, THE SHARES REPRESENTED BY THE PROXY WILL BE VOTED IN ACCORDANCE WITH THE RECOMMENDATIONS OF MANAGEMENT “FOR” THE ELECTION OF ALL NOMINEES FOR DIRECTOR LISTED HEREIN AND “FOR” RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS.

Person Making the Solicitation

This solicitation of proxies is being made by the Board of Directors of the Company. The expense of preparing, assembling, printing, and mailing this proxy statement and the material used in the solicitation of proxies for the meeting will be borne by the Company. It is contemplated that proxies will be solicited principally through the use of the mail, but officers, directors, and employees of the Company and Bank of Marin may solicit proxies personally or by telephone, without receiving special compensation therefor. Although there is no formal agreement to do so, the Company may reimburse banks, brokerage houses, and other custodians, nominees, and fiduciaries for their reasonable expense in forwarding these proxy materials to their principals.

Voting Rights

In connection with the election of directors, in accordance with California law, each shareholder entitled to vote may vote the shares owned by such shareholder as of the Record Date cumulatively if a shareholder present at the meeting has given notice at the meeting, prior to the voting, of his or her intention to vote cumulatively. If any shareholder has given such notice, then all shareholders entitled to vote for the election of directors may cumulate their votes for candidates properly nominated. Under cumulative voting, each share carries as many votes as the number of directors to be elected, and the shareholder may cast all of such votes for a single nominee or may distribute them in any manner among as many nominees as desired. In the election of directors, the twelve nominees receiving the highest number of votes will be elected.

On all other matters submitted to the vote of the shareholders, each shareholder is entitled to one vote for each share of common stock owned on the books of the Company as of the Record Date.

PROPOSAL NUMBER 1:

ELECTION OF DIRECTORS OF THE COMPANY

Directors and Nominees

At the meeting twelve (12) directors of the Company are to be elected to serve until the next Annual Meeting of Shareholders and until their successors are elected and qualified. All of the nominees are currently members of the Board of Directors. The Bylaws of the Company provide for not fewer than nine (9) or more than seventeen (17) directors. By resolution, the Board of Directors has fixed the number of directors at twelve (12), as of May 12, 2009. Currently, the Company has fourteen (14) directors, including all of the nominees for election. Two incumbent directors, J. Patrick Hunt and James E. Deitz, are retiring and will not stand for re-election. Rather than replace these two directors, the Company has determined to reduce the Board size by two, and nominate the remaining twelve (12) incumbent directors for election. The following named persons are nominated by the Board of Directors and, unless the shareholder marks the proxy to withhold the vote, the enclosed proxy, if returned and not subsequently revoked, will be voted in favor of their election as directors. If for any reason any such nominee becomes unavailable for election, the proxy holders will vote for such substitute nominee as may be designated by the Board of Directors. The proxy holders reserve the right to cumulate votes for the election of directors and to cast all of such votes for any one or more of the nominees, to the exclusion of the others, and in such order of preference as the proxy holders may determine in their discretion if cumulative voting is involved as described above under “Voting Rights.”

The following table sets forth the names of, and certain information as of March 17, 2009 with respect to, the persons nominated by the Board of Directors for election as directors and is followed by brief summaries of the background and business experience of each nominee covering at least the last five years. For the year 2008, each of the persons nominated, except for Russell A. Colombo, was “independent” within the meaning of Nasdaq’s listing standards.

Board Committees

The Board of Directors is responsible for the overall affairs of the Company. To assist it in carrying out this responsibility, the Board has delegated certain authority to several committees, the duties of which and membership at the end of 2008 were as follows:

C = Chairman         X = Committee Member

(1) While Mr. Colombo is a member of the Committee and does participate in the recommendation process, he ultimately abstains from voting in the Committee on formal recommendations of director nominees to the board.

The Executive Committee, subject to the provisions of law and certain limits imposed by the Board of Directors, may exercise any of the powers and perform any of the duties of the Board of Directors. The Committee met eleven (11) times in 2008.

The Compensation Committee has primary responsibility for ensuring that compensation and benefits policies and programs for senior management and the Board of Directors comply with applicable law and stock listing requirements, and are devised and maintained to provide and retain a high level of executive management and corporate governance competence. The Committee met thirteen (13) times in 2008.

The Audit Committee, consisting of four independent members as defined in Nasdaq listing standards and Section 10A of the Securities Exchange Act of 1934, selects and recommends appointment of independent auditors, reviews and approves professional services performed by them and reviews the reports of their work together with regulatory agency examination reports. The Committee also reviews and approves the programs, work plan and reports of the Bank’s risk manager and internal auditor. Former Director James D. Kirsner retired from the Board of Directors, effective December 31, 2008 and served as the Company’s Audit Committee financial expert during 2008. Director Thomas M. Foster currently serves as the Company’s Audit Committee financial expert. The Committee met thirteen (13) times in 2008.

The Nominating and Governance Committee assists the Board in carrying out its duties and functions regarding corporate governance oversight and Board membership nominations.

The Committee will consider suggestions or recommendations for Board membership received from shareholders.

Shareholders who wish to make such suggestions or recommendations should forward their written suggestions to the Chairman of the Nominating & Governance Committee addressed to Bank of Marin Bancorp, Attn: Corporate Secretary, 504 Redwood Boulevard, Suite 100, Novato, CA 94947.

educational experience that will be beneficial to the Company. At present, the Committee does not engage a third party to identify and evaluate potential Director candidates.

The Executive, Compensation, Audit, and Nominating and Governance Committee charters are available on the Company’s website at www.bankofmarin.com under the “Investor Relations” tab.

There were nine (9) meetings of the Board of Directors of the Company during 2008.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This section addresses the compensation programs, philosophy and objectives, of Bank of Marin Bancorp and its banking subsidiary, Bank of Marin (collectively, the “Company”), including the process for making compensation decisions, the role of management in the design of such programs, and its 2008 executive compensation components. The factors most relevant to understanding the Company’s compensation programs, which are designed to reward, are addressed including the essential elements of compensation, the reasons for determining payment of each element of compensation, and how each compensation element fits into the Company’s overall compensation objectives and affects decisions regarding other compensation elements.

Philosophy

The Company’s executive compensation programs are designed to attract and retain high quality executive officers that are critical to its long-term success. The Company’s Board of Directors and management believe that the most effective executive compensation program is one that is designed to reward the achievement of specific annual, long-term and strategic goals, which aligns executives’ interests with those of the shareholders by rewarding performance above established goals, with the ultimate goal of improving shareholder value. To that end, the Committee engaged a national human resources consulting firm to conduct a review of the Company’s total compensation program for key executives. Each element of total compensation was compared against a regional peer group, identified by such consulting firm, of 20 publicly traded financial institutions that are similar to the Company in asset size and performance.

The Committee’s compensation philosophy is to target base salaries at or above the median (50th percentile) and target total compensation (including annual incentives, long-term incentives, and benefits) between the 50th and 75th percentiles of the regional peer group. The Company believes targeting total compensation between the 50th and 75th percentile for above-average performance is critical for attracting and retaining the qualified executives it needs to achieve its business objectives. Overall, compensation paid to Company executives is believed to be competitive with market practices.

Base compensation levels for executive officers are established based on the officer’s roles and responsibilities, compensation of executives who perform similar duties, and prior year compensation. Bonus and equity compensation are based on both corporate and/or individual performance objectives, which include asset and revenue growth, identification of strategic opportunities, and core earnings performance.

Process for Making Compensation Decisions

Role of the Executive Officers

Shortly following the conclusion of each calendar year, the Company’s Chief Executive Officer (the “CEO”), assisted by the Director of Human Resources, conducts an annual performance evaluation process for all named executive officers, other than for himself. As part of each annual performance evaluation, the CEO considers, among other key factors, i) financial performance, ii) the executive’s contribution to meeting the Company’s overall goals, iii) the executive’s performance of job responsibilities and achievement of individual and/or departmental objectives and iv) management and leadership skills, including effective communication, problem solving, business development and community involvement.

Based on this evaluation, the CEO determines, for each of the named executive officers (other than himself), recommendations for salary adjustments, including merit increases, and annual incentive award amounts to be made to the Compensation Committee for its approval. The named executive officer’s incentive payment is determined by the Company’s financial performance relative to that year’s financial performance goal and individual performance goals. The Compensation Committee reviews the CEO’s recommendations and can modify a recommended amount in its discretion. In addition, recommendations by management for the grant of stock awards to named executive officers under the Company’s equity compensation plan are submitted to the Compensation Committee for approval to assure the Committee considers the other elements of proposed compensation.

10

Table of Contents

Role of the Compensation Committee

The Compensation Committee has responsibility for establishing, implementing and continually monitoring adherence with the Company’s compensation philosophy. The Compensation Committee ensures that the total compensation paid to senior management is fair, reasonable and competitive. Generally, the types of compensation and benefits provided to the named executive officers are similar to other executive officers. The Compensation Committee is also responsible for the review and approval of corporate goals and objectives relevant to the compensation, including the incentive award, of the Company’s CEO, to evaluate the performance of the CEO in light of the goals and objectives and to determine and approve the CEO’s compensation levels based on this evaluation. Additionally, the Compensation Committee reviews compensation levels for members of the Company’s executive management group including the approval of the CEO’s recommendations on annual bonuses and salary increases for named executive officers.

The Compensation Committee periodically reviews the compensation levels of the Board of Directors. In its review, the Compensation Committee looks to ensure that the compensation is fair, reasonably competitive and commensurate to the amount of work required both from the individual directors as well as from the Board in the aggregate.

To achieve these goals and objectives, the Compensation Committee expects to maintain compensation plans that create an executive compensation program that is set at competitive levels of comparable public financial services institutions with comparable performance.

The Compensation Committee has followed certain fundamental objectives to ensure the effectiveness of the Company’s compensation strategy. These objectives include the following:

11

Table of Contents

Executive Compensation Components

For the fiscal year ended December 31, 2008, the principal components of compensation for named executive officers were i) base salary, ii) performance-based bonuses, iii) equity incentives and iv) perquisites and other benefits. The Company’s policies and practices for each of the principal compensation components are explained in the following paragraphs.

Base Salary

Base salary is established based on market data and is adjusted based on individual performance and experience. The Committee targets total cash compensation to be within 15% of the median for peer companies.

Performance-Based Bonuses

Cash bonuses are based on the overall performance of the Company and on individual goals specific to the executive’s area of responsibility. The overall Company performance goals are based on deposits, loans, net income, return on equity and the efficiency ratio. The cash bonus potential ranges from 30% – 50% of salary depending on the level and responsibilities of the executive.

Equity Incentives

The purposes of equity awards are to allow executives to share in the growth and prosperity of the Company, to retain executives over the long term and to maintain competitive levels of total compensation. Equity incentives for executives must be approved by the Committee.

The 2007 Equity Plan allows the Company to offer multiple equity vehicles as incentives, including options, unrestricted stock, restricted stock, and stock appreciation rights. Executives may be awarded a blend of equity incentives.

Award levels are based upon market and the executive’s level of responsibility and influence on the performance of the Company. Executives are granted stock options and/or restricted stock upon hire and annually thereafter, based on performance. The option and restricted stock price is based on the fair market value on the effective date of the grant. Grants are made at regularly scheduled Committee meetings.

Perquisites and Other Benefits

Consistent with the Company’s compensation objectives, named executive officers are provided perquisites and other benefits that management believes are reasonable and consistent with the Company’s overall compensation program and which keep the Company competitive in the marketplace. The Company periodically reviews the level of perquisites and other benefits provided to the named executive officers for suitability with the program objectives.

12

Table of Contents

The Company is competitive with market practices by providing medical, dental, vision and life insurance, a 401(k) employer matching contribution up to $4,000, an ESOP, an Employee Stock Purchase Plan (the “ESPP”), and a deferred compensation plan for its executives.

Annually, the Company may make discretionary contributions of shares of common stock to the 401(k)/ESOP retirement plan. The decision normally is based on the Company’s financial performance and condition. The purposes of the ESOP are to include all eligible employees in the ownership of the Company, to provide them with compensation that is free from current income tax and to accumulate benefits for retirement. Stock is awarded as a percentage of eligible salary. Executives receive the same percentage as all other employees, up to the IRS limits.

Deferred Compensation Plan

The Company also sponsors an unsecured non-qualified plan known as the Deferred Compensation Plan, which allows named executive officers and certain other highly compensated employees to defer all or a portion of their base salary and/or bonus. Balances in the plan receive earnings all of which are described on page 17 of this Proxy Statement. Other than earnings accruals, all credits to the Deferred Compensation Plan represent a named executive officer’s compensation previously earned and deferred; the Company does not provide any matching or similar credits. The plan was designed to allow named executive officers to defer some of their current income to help them with tax planning, and to assist the Company in attracting and retaining top executives by providing retirement benefits that are competitive within the Company’s peer group.

Employment and Change in Control Agreements

The Company provides named executive officers with agreements that provide for certain specified benefits upon a change in control of the Company. These agreements are very useful tools that help the Company retain its key employees, including the named executive officers, by providing those executives some certainty in compensation in the event the Company were to sell, and also helps ensure the Company will have the benefit of their services through the pendency of any merger. Such agreements are particularly necessary in an industry, such as ours, where there has been considerable consolidation over the last ten years. Detailed information about these agreements, including a description of payout amounts under a hypothetical change in control of the Company as of the last business day of 2008 is included in this Proxy Statement beginning on page 18.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis contained in this Proxy Statement. Based on our Committee review of and the discussions with management with respect to the Compensation Discussion and Analysis, we recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008.

Nonqualified Deferred Compensation for 2008

This plan is intended for a select group of employees of the Company who are in the highest salary band. Employees can defer up to 80% of base salary and up to 100% of bonus compensation into the plan. These are considered irrevocable elections and stay in place for the entire calendar year. The Company does not make any employer contributions to this plan, and employees are always 100% vested in their contributions.

Named executive officers also make an election for distributions from the plan at termination.

Potential Payments Upon Termination or Change in Control

Set forth below is a description of the plans and agreements that could result in potential payments to the named executive officers in the case of their termination of employment and/or a change in control.

Change in Control Agreements

Each named executive officer has signed a Change in Control Agreement. The circumstances that would trigger payment(s) or the provision of other benefits, including perquisites and health care benefits under the Change in Control Agreement are: i) a Change in Control (defined in accordance with Section 409A of the Internal Revenue Code) followed by, ii) the occurrence within one year after the Change in Control of a subsequent “Good Reason,” including:

In the event of a change in control, unvested options immediately vest, and the Company shall pay to executive as severance pay (and without regard to the provisions of any benefit plan) in a lump sum on the fifth day following the date of termination, the average salary of the executive for the last three full years of service multiplied by executive’s Seniority Factor (CEO 2.25 times; EVP 1.50 times); the executive’s annual bonus for the previous year; and, the executive’s health premiums under COBRA for 18 months and Dental/Vision premiums under COBRA for 12 months.

Table of Contents

The table below quantifies the estimated payments and benefits that would be provided to our named executive officers in connection with the termination of his or her employment under the provisions of the Change in Control Agreements.

In all cases, the information assumes that the triggering event occurred on the last day of fiscal year 2008, and the price per share of the Company’s common stock is the closing market price as of that date (which was $23.99).

Termination/Retirement/Disability/Death

Employment Contracts

There are no employment contracts between the Company or the Bank and their executive officers except Bank of Marin Bancorp has an employment agreement with Russell A. Colombo, its President and Chief Executive Officer. The agreement has a two-year term commencing on December 1, 2008, and renews annually on December 1^st of each year unless a party gives written notice to the other within certain time periods. The agreement establishes a base salary of $281,036 and allows for an increase annually. As of January 1, 2009 the base salary is $281,036. The agreement also provides the potential to earn an annual incentive payment of up to fifty percent (50%) of executive’s salary, participation in the Company’s reimbursement policy and participation in the Company’s benefit plans that are available to senior executives and employees generally. The agreement also provides for payment of an automobile allowance of Eight Hundred Dollars ($800) per month, a reimbursement for monthly membership dues for the Marin Country Club, and reimbursement for necessary air travel expenses for Russell A. Colombo’s spouse up to a maximum of $2,000 per year. If the agreement were terminated without cause, Mr. Colombo would receive severance pay equal to one year’s annual base salary in effect at the date of termination plus eighteen months’ COBRA payments for health premiums and dental/vision premiums.

Employee Stock Ownership & Profit Sharing Plan

In October 1995 the Board of Directors authorized the amendments to and restatement of the Bank of Marin 401(k) Plan to the Bank of Marin Employee Stock Ownership and Savings Plan, which was subsequently adopted by Bank of Marin Bancorp, effective July 1, 2007. An employee becomes a participant in the plan as of the first day of the quarter following the date on which he/she attains age 18 and has completed three full months of service. A participant may elect to defer a portion of his/her salary, not to exceed limitations set by the IRS, into the plan. As determined by the Board of Directors, the Company may make discretionary matching and/or profit sharing contributions to the plan. In 2008 and 2007 the Company made matching contributions to the plan of $358 thousand and $382 thousand, respectively. The Company’s profit sharing contributions to the plan of $760 thousand in 2008 and $850 thousand in 2007 were used to purchase shares of Company stock for the plan. Distributions from the plan are not permitted before age 59 ¹/2 except in the event of death, termination of employment or proven financial hardship.

Discretionary Bonus

Bank of Marin has discretionary bonus programs for the Bank’s executive officers, and for the non-executive officers and staff. Contributions by the Bank to both programs are based upon the Bank’s achievement of specified levels of financial performance as determined by the Board of Directors. In 2008 the Bank expensed $1,128,046 for these programs, and bonus payments were made in the first quarter of 2009.

Director Compensation

The following table sets forth certain information regarding the compensation earned by or awarded to each director who served on the Board of Directors in 2008.

Indebtedness and Other Transactions with Directors and Executive Officers

In accordance with the Nominating and Governance Committee Charter, the Nominating and Governance Committee is responsible for reviewing and acting upon all related party transactions required to be disclosed by Item 404 of Regulation S-K for potential conflicts of interest. Additionally, the Company’s Code of Ethical Conduct provides rules that restrict transactions with affiliated persons.

Prior to engaging in any related party transaction, a completed questionnaire describing the nature and structure of the transaction, along with any necessary supporting documentation, is submitted to the Nominating and Governance Committee. In determining whether to approve a related party transaction, the Nominating and Governance Committee will consider, among other things, the following:

The Company will only enter into a related party transaction if the Nominating and Governance Committee determines that the transaction is beneficial to the Company, and the terms of the transaction are fair to the Company.

In March 2008, the Nominating and Governance Committee approved a related party transaction between Bank of Marin and McDevitt & McDevitt Construction Corp to perform tenant improvements, under the direction of Bank management, for the Bank’s new Mill Valley branch. The transaction involved approximately $608,000 in construction related costs and overhead. The Company’s director, William H. McDevitt, Jr., is a 50% owner of McDevitt & McDevitt Construction Corp and realized revenue related to this construction project. Mr. McDevitt was only involved in the initial consultation regarding this project, and an alternate representative from McDevitt & McDevitt Construction Corp was the Bank’s direct liaison on the project. The Committee determined that the transaction is beneficial to the Company, and the terms of the transaction are fair to the Company. No waiver of the Company’s Code of Ethical Conduct was required in approving the transaction.

Additionally, the Company’s subsidiary, Bank of Marin, has had and expects to have banking transactions in the ordinary course of business with many of the directors and executive officers of the Bank (and their associates), on substantially the same terms (including interest rates, collateral and repayment terms) as those prevailing for comparable transactions with others. During 2008 no loan to any director or executive officer of the Company (or their associates) has involved more than normal risk of collectibility or presented other unfavorable features. All loans to directors or executive officers would be subject to the limitations prescribed by California Financial Code Section 3370, et seq. and by the Financial Institutions Regulatory and Interest Rate Control Act of 1978. With respect to transactions other than loans, the Company has had and expects to have such transactions in the ordinary course of business with its directors and executive officers (and their associates), but all such transactions have been and will be on substantially the same terms as those prevailing for comparable transactions with others.

PROPOSAL NUMBER 2:

INDEPENDENT AUDITORS

The firm of Moss Adams LLP, independent auditors, has been selected by the Audit Committee of the Board of Directors to perform audit services for the Company and its subsidiary, Bank of Marin, for 2009 and such selection has been approved by resolution of the Board of Directors. The shareholders are hereby asked to ratify the selection of Moss Adams LLP. It is anticipated that a member of that firm will be present at the Annual Meeting. That representative is not expected to make a statement but will be available to answer any questions.

During the two most recent fiscal years there were no disagreements between the Company and its principal accountants on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the principal accountant’s satisfaction, would have caused the principal accountant to make reference to the subject matter of the disagreement in connection with its reports.

The audit reports on the financial statements of Bank of Marin Bancorp and subsidiary as of and for the fiscal years ended December 31, 2008, 2007 and 2006 were issued by Moss Adams LLP and did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

Following are disclosures regarding the fees billed by Moss Adams LLP during 2007 and 2008. It is the policy of the Audit Committee that all engagements for auditing services, and non-audit services be preapproved by the Audit Committee. The preapproval includes a review of the services to be undertaken and the estimated fees that will be incurred. The Audit Committee has considered whether the provision of non-audit services by Moss Adams LLP is compatible with maintaining auditor independence.

Audit Fees

The aggregate fees billed for professional services in the fiscal year 2008 and 2007 by Moss Adams LLP for the audit of the annual financial statements, review of the quarterly financial statements and work related to compliance with the Sarbanes-Oxley Act of 2002 were $261,319 and $258,489, respectively.

Audit-Related Fees

There were no audit-related fees in 2008 related to consents provided by Moss Adams LLP for the use of the 2007 audit report in 8-K filings. There were $9,700 in audit-related fees in 2007 related to consents provided by Moss Adams LLP for the use of the 2006 audit report in various 8-K filings.

Tax Fees

The Company does not engage its principal accountant, Moss Adams LLP, to perform tax-related services.

All Other Fees

There were no other fees billed by the Company’s principal accountant in 2008 or 2007.

Preapproval of Services by Principal Accountant

The Audit Committee will consider annually and, if appropriate, approve audit services by its principal accountant. In addition, the Audit Committee will consider and, if appropriate, preapprove certain defined audit and non-audit services. The Audit Committee will also consider on a case-by-case basis and, if appropriate, approve specific engagements.

Audit Committee Report

The Audit Committee currently consists of four members of the Board of Directors, each of whom is independent under the Nasdaq listing standards, SEC rules and regulations applicable to audit committees. The Board of Directors has adopted, and annually reviews, an Audit Committee charter, available on the Company’s investor

21

Table of Contents

relations website at www.bankofmarin.com. The charter specifies the scope of the Audit Committee’s responsibilities and how it carries out those responsibilities.

In performing its functions, the Audit Committee met thirteen (13) times during the year. It acts only in an oversight capacity and necessarily relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent accountants, who, in their report, express an opinion on the conformity of the Company’s annual financial statements to accounting principles generally accepted in the United States of America and on the Company’s internal control over financial reporting and compliance. It also maintains a process for handling employee complaints regarding accounting procedures and internal controls.

The Audit Committee has reviewed and discussed the Company’s December 31, 2008 audited financial statements with management and with Moss Adams LLP, the Company’s independent registered public accounting firm. The Audit Committee also has discussed with Moss Adams LLP the matters required to be discussed by the statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

The Audit Committee also has received from Moss Adams LLP the written disclosures and the letter required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed with Moss Adams LLP their independence from the Company.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the December 31, 2008 audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2008.

Submitted by the Audit Committee of the Board:

Stuart D. Lum, Chair

Thomas M. Foster

Joseph D. Martino
