PROXY STATEMENT

March 13, 2017

GENERAL

The Westamerica Board of Directors is soliciting proxies to be used at the 2017 Annual Meeting of Shareholders of Westamerica Bancorporation (the “Company”), which will be held at 11:00 a.m. Pacific Time, Thursday, April 27, 2017, or at any adjournment or postponement of the Annual Meeting. Proxies are solicited to give all Shareholders of Record (“registered holder”) an opportunity to vote on matters to be presented at the Annual Meeting. In the following pages of this Proxy Statement, you will find information on matters to be voted at the Annual Meeting.

Voting Information

Internet Availability of Proxy Materials. We are providing proxy materials to our shareholders primarily via the internet, instead of mailing printed copies of those materials to each shareholder. By doing so, we save costs and reduce the environmental impact of our Annual Meeting. On or about March 13, 2017, we mailed a Notice of Internet Availability of Proxy Materials (“Notice”) to certain of our shareholders. The Notice contains instructions about how to access our proxy materials and vote online or vote by telephone. If you would like to receive a paper copy of our proxy materials, please follow the instructions included in the Notice. If you previously chose to receive our proxy materials electronically, you will continue to receive access to these materials via email unless you elect otherwise.

Proof of Ownership May Be Required for Attending Annual Meeting in Person. You are entitled to attend the Annual Meeting only if you are a shareholder as of the close of business on February 27, 2017, the record date, or hold a valid proxy for the meeting. In order to be admitted to the Annual Meeting, the Company reserves the right to request proof of ownership of Westamerica Bancorporation common stock on the record date. This can be:

· A brokerage statement or letter from a bank or broker indicating ownership on February 27, 2017;

· The Notice of Internet Availability of Proxy Materials;

· A printout of proxy distribution email (if you received your materials electronically);

· A Proxy Card;

· A voting instruction form; or

· A legal proxy provided by your broker, bank or nominee.

Any holder of a proxy from a shareholder must present the Proxy Card properly executed, and a copy of the proof of ownership. The Company reserves the right to ask shareholders and proxy holders to present a form of photo identification such as a driver’s license.

Proxy Card. The Board has designated Arthur C. Latno, Jr., Ronald A. Nelson and Edward B. Sylvester to serve as Proxies for the Annual Meeting. As Proxies, they will vote the shares represented by proxies at the Annual Meeting. If you sign, date and return your Proxy Card but do not specify how to vote your shares, the Proxies will vote FOR the election of all of the Director nominees, FOR approval of the advisory vote on the compensation of our named executive officers, FOR the re-approval of our performance criteria for incentive compensation; EVERY ONE YEAR for the advisory vote on the frequency of the advisory vote on compensation of our named executive

1

officers, FOR ratifying the selection of independent auditor, and AGAINST the shareholder proposal regarding an independent board chairman. The Proxies will also have discretionary authority to vote in accordance with their judgment on any other matter that may properly come before the Annual Meeting that we did not have notice of by January 28, 2017.

Quorum and Shares Outstanding. A quorum, which is a majority of the total shares outstanding as of the record date, must be present to hold the Annual Meeting. A quorum is calculated based on the number of shares represented by shareholders attending in person or by proxy. On February 27, 2017, 26,273,817 shares of Westamerica Bancorporation common stock were outstanding. We also count broker non-votes, which we describe below, as shares present or represented at the Annual Meeting for the purpose of determining whether a quorum exists.

Election of Director Nominees. Each share is entitled to one vote, except in the election of Directors where a shareholder may cumulate votes as to candidates nominated prior to voting, but only when a shareholder gives notice of intent to cumulate votes prior to the voting at the Annual Meeting. If any shareholder gives such notice, all shareholders may cumulate their votes for nominees. 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 distribute them in any manner among as many nominees as desired. This Proxy Statement solicits the discretionary authority to cumulate votes and allocate them in the Proxy Holders’ discretion if any shareholder requests cumulative voting. In the election of Directors, the nine nominees receiving the highest number of votes will be elected. If your proxy is marked “Withhold” with regard to the election of any nominee, your shares will be counted toward a quorum and for other nominees but they will not be voted for the election of that nominee. If you attend the Annual Meeting and have already voted, you may vote in person in order to rescind your previous vote.

Vote Required; Effect of Abstentions and Broker Non-Votes. The shares of a shareholder whose ballot on any or all proposals is marked as “abstain” will be included in the number of shares present at the Annual Meeting to determine whether a quorum is present. If you are the beneficial holder of shares held by a broker or other custodian, you may instruct your broker how to vote your shares through the voting instruction form included with this Proxy Statement. If you wish to vote the shares you own beneficially at the meeting, you must first request and obtain a legal proxy from your broker or other custodian. If you choose not to provide instructions or a legal proxy, your shares are referred to as “uninstructed shares.” Whether your broker or custodian has the discretion to vote these shares on your behalf depends on the ballot item. The following table summarizes the votes required for passage of each proposal and the effect of abstentions and uninstructed shares held by brokers.

Brokers and custodians cannot vote uninstructed shares on your behalf in director elections or advisory votes on executive compensation. For your vote to be counted, you must submit your voting instruction form to your broker or custodian.

Other Matters. Approval of any other matter considered at the Annual Meeting will require the affirmative vote of a majority of the shares present or represented by proxy and voting at the Annual Meeting.

How You Can Vote. Your vote is very important and we hope that you will attend the Annual Meeting. However, whether or not you plan to attend the Annual Meeting, please vote by proxy.

Registered Holders. If your shares are registered directly in your name with the Company’s transfer agent, Computershare Investor Services, LLC, you are considered a registered holder of those shares. Please vote by proxy in accordance with the instructions on your Proxy Card, or the instruction you received by email.

A registered holder can vote in one of the following four ways:

· Via the Internet. Go to the website noted on your Proxy Card in order to vote via the internet. Internet voting is available 24 hours a day. We encourage you to vote via the internet, as it is the most cost-effective way to vote. When voting via the internet, you do not need to return your Proxy Card.

· By Telephone. Call the toll-free telephone number indicated on your Proxy Card and follow the voice prompt instructions to vote by telephone. Telephone voting is available 24 hours a day. When voting by telephone, you do not need to return your Proxy Card.

· By Mail. Mark your Proxy Card, sign and date it, and return it in the enclosed postage-paid envelope. If you elected to electronically access the Proxy Statement and Annual Report, you will not be receiving a Proxy Card and must vote via the internet or by telephone.

· In person. You may vote your shares at the Annual Meeting if you attend in person, even if you previously submitted a Proxy Card or voted via internet or telephone. Whether or not you plan to attend the Annual Meeting, however, we strongly encourage you to vote your shares by proxy before the meeting.

We have been advised by counsel that these telephone and internet voting procedures comply with California law.

Beneficial Shareholders. If your shares are held in a brokerage account in the name of your bank, broker, or other holder of record (“beneficial holder” or “street name”), you are not a registered holder, but rather are considered a

3

beneficial holder of those shares. Your bank, broker, or other holder of record will send you instructions on how to vote your shares. If you are a beneficial holder, you must obtain a legal proxy, executed in your favor, from the holder of record to be able to vote in person at the Annual Meeting.

Voting Deadlines. If you are a participant in the Westamerica Bancorporation Tax Deferred Savings/Retirement Plan (ESOP) your vote must be received by 11:59 p.m. Central Time, on April 24, 2017. All other shareholders voting by telephone or internet must vote by 12:01 a.m. Central Time, on April 27, 2017 to ensure that their vote is counted.

Revocation of Proxy. Registered Holders who vote by proxy, whether by telephone, internet or mail, may revoke that proxy at any time before it is voted at the Annual Meeting. You may do this by: (a) signing another Proxy Card with a later date and delivering it to us prior to the Annual Meeting or sending a notice of revocation to the Corporate Secretary of Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting at a later time by telephone or on the internet prior to 12:01 a.m. Central Time, on April 27, 2017 (prior to 11:59 p.m. Central Time, on April 24, 2017 for ESOP participants); or (c) attending the Annual Meeting in person and casting a ballot. If you are a beneficial holder, you may change your vote by submitting new voting instructions to your broker or other nominee.

Additional Information

Householding. As permitted by the Securities Exchange Act of 1934 (the “Exchange Act”) only one envelope containing two or more Notices of Internet Availability of Proxy Materials is being delivered to shareholders residing at the same address, unless such shareholders have notified their bank, broker, Computershare Investor Services, or other holder of record that they wish to receive separate mailings. If you are a beneficial holder and own your shares in street name, contact your broker, bank or other holder of record to discontinue householding and receive your own separate copy of the Notice in future years. If you are a registered holder and own your shares through Computershare Investor Services, contact Computershare toll-free at 877-588-4258 or in writing directed to Computershare Investor Services, 250 Royall Street, Mail Stop 1A, Canton, MA 02021 to discontinue householding and receive multiple Notices in future years.

Mailing of dividends, dividend reinvestment statements, and special notices will not be affected by your election to discontinue duplicate mailings of the Notice.

If you hold your Westamerica Bancorporation common stock in street name through a broker, a bank or other nominee, you may have the option of securing your Proxy Statement and Annual Report via the internet. If you vote this year’s proxy electronically, you may also elect to receive future Proxy Statements, Annual Reports and other materials electronically by following the instructions given by your bank, broker, or other holder of record when you vote.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities and Exchange Act requires the Company’s Directors and Executive Officers and persons who own more than ten percent (10%) of a registered class of the Company’s equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Our employees generally prepare these reports on the basis of information received from each Director and Officer. Based on the review of copies of the forms filed, the Company believes that, during the last fiscal year, all filing requirements under Section 16(a) applicable to its directors, officers, and 10% shareholders were filed timely.

PROPOSAL 1 – ELECTION OF DIRECTORS

Board of Directors

Nine Directors have been nominated for election at the Annual Meeting to hold office until the next Annual Meeting or until their successors are elected and qualified. The Proxies will vote for the nine nominees named below unless you give different voting instructions on your Proxy Card. Each nominee is presently a Director of the Company and has consented to serve a new term. The Board does not anticipate that any of the nominees will be unavailable to serve as a Director, but if that should occur before the Annual Meeting, the Board reserves the right to substitute another person as nominee. The Proxies will vote for any substitute nominated by the Board of Directors. The Proxies may use their discretion to cumulate votes for election of Directors and 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 they may determine at their discretion.

Nominees

The nominees for election as Directors are named and certain information with respect to them is given below. Our nominees are seasoned leaders who bring to the Board an array of financial services, public and private company, non-profit, and other business experience. As a group they possess experience in leadership, consumer banking, commercial and small business banking, investment banking, capital markets, financial advisory services, finance and accounting, risk management and real estate. Many of the Board Members have seen the Company through a variety of economic conditions. The information below has been furnished to the Company by the respective nominees. All of the nominees have engaged in their indicated principal occupation for more than five years, unless otherwise indicated and no nominee has served on the Board of Directors of another public company during the past five years.

Name of Nominees, Principal Occupations, and Qualifications

THE BOARD OF DIRECTORS RECOMMENDS ELECTION OF ALL NOMINEES

Board of Directors and Committees

Director Independence and Leadership Structure

The Board of Directors has considered whether any relationships or transactions related to a Director were inconsistent with a Director’s independence. Based on this review, the Board has determined that E. Allen, L.E. Bartolini, E.J. Bowler, A.C. Latno, Jr., P.D. Lynch, C.C. MacMillan, R.A. Nelson, and E.B. Sylvester are “independent” Directors as defined in NASDAQ rules.

Our Board has carefully considered the critical issue of Board leadership. In the context of risk management, the leadership of each Board committee primarily responsible for risk management is vested in an independent committee chair. With regard to the leadership of the meetings of the full Board, our Board of Directors has carefully evaluated whether the positions of chairman and CEO should be separate or combined. Our Board believes that the most effective leadership structure for the Company at this time is to combine the responsibilities of the Chairman and CEO, a structure that has been successful since 1989. The combined positions avoid a duplication of efforts, enable decisive leadership, ensure a clear accountability for the performance of the Company, a more rapid implementation of decisions, and a consistent vision. Given the size of our employee base and our level of assets relative to larger, more complex banking structures, our Company is particularly well suited to combine the Chairman and CEO functions. Furthermore, our management team has an average tenure of 23 years and does not require the substantial oversight needed by a less experienced team, which has allowed our Chairman and CEO to lead the Company through eleven acquisitions since 1992.

To ensure strong Board oversight eight of our nine Directors are, as noted above, independent as defined by NASDAQ. Only non-management directors sit on Board committees, with the exception of the Executive Committee, and every non-management director sits on one or more of these Committees. All non-management directors meet at least four times a year outside the presence of the Chairman and CEO. The Board completes an annual board evaluation that is discussed by the Nominating Committee and presented to the full Board.

Although the Board believes that it is more effective to have one person serve as the Chairman and CEO at this time, it also recognizes the importance of strong independent leadership on the Board, accordingly, the Board has established a strong, independent Lead Director, Mr. Sylvester, who must serve at least one year and has the following clearly delineated and comprehensive duties:

· Presides at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent Directors;

· Serves as liaison between the Chairman and the independent Directors;

· Approves information sent to the Board;

· Approves meeting agendas for the Board;

· Approves meeting schedules to assure that there is sufficient time for discussion of all agenda items;

· Has the authority to call meetings of the independent Directors; and

10

· If requested by major shareholders, ensures that he or she is available for consultation and direct communication.

The Board does not believe that the fact an independent Lead Director does not preside over the normal Board meeting business sessions limits the ability of the Board to have open exchanges of views, or to address any issues the Board chooses, independently of the Chairman.

The Board of Directors of the Company also serve as the Board of Directors of Westamerica Bank, and as such are well informed of Bank operations through regular reports and discussions on the operations of the Bank. The Directors’ longevity with the Company has exposed them to a wide range of business cycles, which plays a critical role in managing the risk profile and profitability of the Company through the current economic environment.

Role of the Board of Directors in Risk Oversight

The Board is also responsible for overseeing all aspects of management of the Company, including risk oversight, which is effected through all Board committees, but primarily through the Board’s Audit Committee. The Internal Audit Department reports directly to the Board’s Audit Committee. It presents its independently prepared company-wide annual risk assessment, its evaluation of Management’s prepared risk assessment and its audit plan incorporating the risk assessment, including the policies and procedures utilized to monitor and control such exposures, to the Board’s Audit Committee.

The internal loan review function reports directly to the Board’s Loan and Investment Committee. It reports ongoing evaluations of loan portfolios and the risk rating of individual loans using guidelines established by bank regulatory authorities, to the Board’s Loan and Investment Committee.

Meetings

The Company expects all Board members to attend all meetings, including the Annual Meeting of Shareholders, except for reasons of health or special circumstances. The Board held a total of ten meetings during 2016. Every Director attended at least 75% of the aggregate of: (i) the Board meetings held during that period in which they served; and (ii) the total number of meetings of any Committee of the Board on which the Director served. Each individual who served on the Board of the Company on the date of the 2016 Annual Meeting of Shareholders attended the meeting, except for Mr. Bartolini.

Executive Committee

Functions: The Board delegates to the Executive Committee all powers and authority of the Board in the management of the business affairs of the Company between board meetings, which the Board is allowed to delegate under California law.

Audit Committee

The Board of Directors has determined that all members are independent, as that term is defined by applicable rules of NASDAQ for Audit Committee purposes. The Board has also designated Mr. Nelson as the “Audit Committee financial expert” as defined by the rules of the SEC and has determined that he is “financially sophisticated” under NASDAQ rules. In concluding that Mr. Nelson is the Audit Committee financial expert, the Board determined that he has:

· an understanding of generally accepted accounting principles and financial statements;

· the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves;

· experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company’s financial statements, or experience actively supervising one or more persons engaged in such activities;

· an understanding of internal control over financial reporting; and

· an understanding of Audit Committee functions.

Designation of a person as an Audit Committee financial expert does not result in the person being deemed an expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose on the person any duties, obligations or liability greater than those imposed on any other Audit Committee member or any other Director and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.

Functions: The Audit Committee provides independent, objective oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the independence and performance of the Company’s independent auditor as it performs audit, review or attest services, and the Company’s internal audit and control function. It selects and retains the independent registered public accounting

12

firm, and reviews the plan and the results of the auditing engagement. It acts pursuant to a written charter that was reaffirmed by the Board of Directors in January 2017 and is attached as Exhibit A to the Proxy Statement for this 2017 Annual Meeting of Shareholders.

Employee Benefits and Compensation Committee

The Employee Benefits and Compensation Committee of the Board of Directors (the “Compensation Committee”) is comprised solely of Directors who are not current or former employees of Westamerica or any of its affiliates. They are independent as defined by NASDAQ rules.

Functions: The Compensation Committee administers Westamerica Bancorporation’s 2012 Amended and Restated Stock Option Plan of 1995, Tax Deferred Savings and Retirement Plan, Deferred Profit Sharing Plan, Deferred Compensation Plan, and the Westamerica Bancorporation Deferral Plan. It administers the Company’s compensation programs and reviews and reports to the Board the compensation level for executive officers, including the CEO, of the Company and its subsidiaries and determines that compensation plans are balanced between financial results and prudent risk taking. The Compensation Committee determines annual corporate performance objectives for equity compensation and cash bonuses and their related corporate, divisional and individual goals. Based on the CEO’s assessment of the extent to which each executive officer met those objectives and goals, the Committee determines each executive officer’s annual equity compensation and cash bonus. The Compensation Committee also establishes the individual goals and targets for the CEO. All compensation approved by the Compensation Committee is reported to the full Board of Directors. The role of the Compensation Committee is described in greater detail under the section entitled “Compensation Discussion and Analysis.”

The Compensation Committee is governed by a written charter as required by NASDAQ rules. The charter was reaffirmed by the Board of Directors in January 2017 and is attached as Exhibit B to the Proxy Statement for this 2017 Annual Meeting of Shareholders. The Compensation Committee has the authority to seek assistance from officers and employees of the Company as well as external legal, accounting and other advisors. It has not retained outside consultants for compensation advice, but can request assistance on an as-needed basis. It does not delegate authority to anyone outside of the Compensation Committee. The Payroll and Employee Benefits Department supports the Compensation Committee by fulfilling certain administrative duties regarding the compensation programs.

Nominating Committee

The Board of Directors has determined that all members of the Nominating Committee are independent, as defined in NASDAQ rules.

Functions: The Nominating Committee screens and recommends qualified candidates for Board membership. This Committee recommends a slate of nominees for each Annual Meeting. As part of that process, it evaluates and considers all candidates submitted by shareholders in accordance with the Company’s Bylaws, and considers each existing Board member’s contributions. The Committee applies the same evaluation standards whether the candidate was recommended by a shareholder or the Board. The Nominating Committee is governed by a written charter, which was reaffirmed January 27, 2016 and attached as Exhibit B to the Proxy Statement for the 2016 Annual Meeting of Shareholders.

While the Board does not have a formal diversity policy, it broadly defines diversity to encompass a diverse range of skills and expertise sufficient to provide prudent guidance to the Company. In addition to the qualifications and characteristics described below, it considers whether the potential Director assists in achieving a mix of Board members that represents a diversity of background, perspective, and experience. Our Board includes Directors with experience in public corporations and non-profit organizations, as well as entrepreneurial

13

individuals who have successfully run their own private enterprise. Our Board also has a broad set of skills necessary for providing oversight to a financial institution, which includes proven leadership, and expertise in capital management, finance, accounting, regulatory affairs, and investment management.

Nominating Directors. The Nominating Committee will consider shareholder nominations submitted in accordance with Section 2.14 of the Bylaws of the Company. That section requires, among other things, that nominations be submitted in writing and must be received by the Corporate Secretary at least 45 days before the anniversary of the date on which the Company first mailed its proxy materials for the prior year’s Annual Meeting of Shareholders. If the date for the current year’s Annual Meeting changes more than 30 days from the date on which the prior year’s meeting was held, the Company must receive notice with a reasonable amount of time before the Company mails its proxy materials for the current year.

Compensation Discussion and Analysis

The executive compensation practices described below have been followed consistently for twenty-four years. At each Annual Meeting of Shareholders since 2010, a majority of our shareholders approved an advisory proposal on the Company’s executive compensation.

The Compensation Committee governs the executive compensation program that combines three compensation elements: base salary, annual non-equity cash incentives, and long-term stock grants. Several compensation philosophies and practices underlie this program:

· Base salaries for participants in this program should be limited to foster an environment where incentive compensation motivates and rewards corporate, divisional, and individual performance.

· Incentive compensation (annual non-equity cash incentives and long-term stock grants) is based on measurement of performance against pre-established objective measurable goals. Specific criteria for each objective are established for “threshold,” “target,” and “outstanding” performance. On any one measure, performance below “threshold” results in no credit for that objective. “Threshold” performance results in 75% achievement, “target” performance results in 100% achievement, and “outstanding” performance results in 150% achievement. The performance achievement level determines the size of incentive compensation awards.

· Long-term incentive stock grants will be awarded to senior management if the corporate performance level is rated “threshold” or better. The purpose of long-term incentive grants is to:

– Motivate senior management to focus on long-term performance;

– Avoid excessive risk-taking and instill conservative management practices;

– Build equity ownership among Westamerica’s senior management;

– Link shareholder interests to management incentives; and

– Create ownership mentality among senior management.

In February 2013, the Board of Directors adopted a clawback policy that requires executive officers to forfeit previously awarded incentive compensation if the incentives were based on materially inaccurate financial statements or other performance measures that are later proven to be materially inaccurate or the achievement of which were due to fraud or other misconduct.

Establishing Incentive Levels, Determining Objectives and Measuring Performance

In administering the executive compensation program, the Compensation Committee determines “target” incentives for each position annually. The Compensation Committee exercises discretion in establishing “target”

16

incentives in an effort to provide competitive pay practices while motivating and rewarding performance that benefits the Company’s long-term financial performance and shareholder interests, and avoiding excessive risk-taking.

At the beginning of each calendar year, the Compensation Committee establishes annual corporate performance objectives. In establishing corporate performance objectives, the Compensation Committee takes into consideration the current operating environment for the commercial banking industry as well as internal management policies and practices which would, in the Compensation Committee’s opinion, benefit the long-term interests of the Company and its shareholders. Corporate performance measures include risk management elements considered to be responsive to the impact that current operating conditions could have on the long-term performance of the Company. The Compensation Committee monitors the economy and the banking industry’s operating environment throughout the ensuing year, and may exercise discretion in adjusting corporate performance objectives during the year.

The operating environment for the commercial banking industry is impacted by a myriad of factors including, but not limited to, local, national and global economic conditions, interest rate levels and trends, monetary policies of the Federal Reserve Board and its counterparts in other countries, fiscal policies of the United States government and other global political conditions, regulations and legislation, liquidity in capital markets, the demand for capital by commercial enterprises and consumers, new financial products, competitive response to changing conditions within the industry, trade balances, the changing values of real estate, currencies, commodities and other assets, and other factors.

Management policies and practices the Board considers in establishing corporate performance objectives include, but are not limited to, management of the Company’s balance sheet and product pricing in a manner which will benefit the long-term financial interests of shareholders, the type and variety of financial products offered by the Company, adherence to internal controls, management of the credit risk of the Company’s loan and investment portfolios, the results of internal, regulatory and external audits, service quality delivered to the Company’s customers, service quality of “back office” support departments provided to those offices and departments directly delivering products and services to the Company’s customers, maintenance of operating policies and procedures which remain appropriate for risk management in a dynamic environment, timely and efficient integration of acquired companies, operational efficiencies, and capital management practices.

Restricted performance shares (“RPS”) represent awards of Westamerica Bancorporation’s common stock subject to achievement of performance objectives established by the Compensation Committee. The 2012 Amended and Restated Stock Option Plan of 1995 (the “2012 Amended Plan”), which was originally approved by shareholders in 1995, and amended with shareholder approval in 2003 and again in 2012, defines the performance factors the Board must use in administering RPS grants as one or more of the following: earnings, diluted earnings per share, revenue and revenue per diluted share, expenses, share price, return on equity, return on equity relative to the average return on equity for similarly sized institutions, return on assets, return on assets relative to the average return on assets for similarly sized institutions, efficiency ratio (operating expenses divided by operating revenues), net loan losses as a percentage of average loans outstanding, nonperforming assets, and nonperforming assets as a percentage of total assets.

In addition to establishing corporate performance objectives, the Compensation Committee also establishes individual goals for the CEO. In regard to the other executives named in the accompanying tables, the CEO recommends divisional and individual performance objectives to the Compensation Committee, which considers, discusses, adjusts as necessary, and adopts such performance objectives.

Upon the closure of each calendar year, the Compensation Committee reviews corporate, divisional, and individual performance against the performance objectives for the year just completed. After thorough review and deliberation, the

17

Compensation Committee determines the recommended amount of individual non-equity cash incentives and stock-based incentive awards. The Compensation Committee reports such incentives to the Board of Directors. Meetings of the Compensation Committee and Board of Directors routinely occur in January, immediately following the closure of the calendar year for which performance is measured for incentive compensation purposes.

Stock Grants

Long-term stock grants may only be awarded under shareholder approved stock-based incentive compensation plans. The Company’s Proxy Statement dated March 12, 2012, as filed with the SEC on March 13, 2012, summarizes the 2012 Amended Plan’s changes from the predecessor plan. Such changes included:

· reducing the issuable shares to 1,500,000 (plus shares that become available if awards under prior plans expire unexercised or are cancelled, forfeited or terminated before being exercised);

· any additional authorization of shares available for issuance must be approved by shareholders; and

· establishing a plan expiration date of April 26, 2022 after which shareholder approval is again required to extend the term or approve a new stock option plan.

The 2012 Amended Plan allows four types of stock-based compensation awards:

Incentive Stock Options (“ISO”) allow the optionee to buy a certain number of shares of Westamerica Bancorporation common stock at a fixed price, which is established on the date of the option grant. ISOs are intended to meet the requirements of Section 422 of the Internal Revenue Code which provide advantages if certain conditions are met. If the optionee holds the acquired stock for the designated holding period, the optionee defers the timing of recognizing taxable income related to exercising the ISO. If the optionee complies with the ISO requirements, the Company does not receive a corporate tax deduction related to the shares issued.

Nonqualified Stock Options (“NQSO”) also give the optionee the option to buy a certain number of shares of Westamerica Bancorporation common stock at a fixed price, which is established on the date of grant. Unlike ISOs, NQSOs do not allow deferral of taxable income for the optionee. At the time NQSOs are exercised, the optionee incurs taxable income equal to the spread between the exercise price and the market price of the stock, and the Company receives a corporate tax deduction in the same amount.

Stock Appreciation Rights (“SAR”) provide the holder a cash payment equal to the difference between the fair market value of the Westamerica Bancorporation’s common stock on the date the SAR is surrendered and the fair market value of the Company’s common stock on the date the SAR was granted. The optionee incurs taxable income at the time the SAR is settled and the Company receives a corporate tax deduction in the same amount.

Restricted Performance Share Grants, as noted above, are awards of the Westamerica Bancorporation’s common stock that are subject to the achievement of performance objectives. Award recipients receive shares at the end of the performance measurement period only if performance objectives are achieved. The award recipient incurs taxable income at the time any RPS vests and the Company receives a corporate tax deduction in the same amount.

Determination of Awards to Grant

In determining which type of stock-based compensation awards to grant, the Compensation Committee considers the attributes of each form of incentive. Examples include the ability to motivate management to make decisions based on the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax consequences of each type of award. The Compensation Committee retains the latitude to utilize all forms of incentives provided under the 2012 Amended Plan. In the current and preceding years, the Compensation Committee has utilized NQSO and RPS based on the motivational aspects of stock price appreciation, the settlement in shares rather than cash, and the preservation of tax deductions for the Company. As of February 27, 2017, the Company had no ISO or SAR awards outstanding.

The 2012 Amended Plan also requires the exercise price of each NQSO or ISO to be no less than one hundred percent (100%) of the fair market value of the Company’s common stock on the date of grant. The 2012 Amended Plan does not allow re-pricing stock options for poor stock price performance.

Stock-based compensation awards are submitted by the Compensation Committee to the full Board of Directors for review. As described above, these meetings have routinely occurred in January immediately following the closure of the calendar year for which performance is measured for incentive compensation purposes. The Compensation Committee meeting has routinely been held during the same week as the related Board of Directors meeting. These January meetings follow by no more than ten business days the Company’s public disclosure of its financial results for the preceding year. As a result, stock option grants are awarded, and the exercise price of such grants are determined at a time when the Company has broadly disseminated its financial condition and current operating results to the public. The Company’s outstanding stock option grants are dated, and related stock option exercise prices are determined, on the January date the Compensation Committee meets to approve such grants.

Long-Term Incentive Attributes

The Board of Directors has designated the Compensation Committee as the administrator of the 2012 Amended Plan. The Compensation Committee reports to the Board the terms and conditions of stock option awards. In carrying out this responsibility, the Compensation Committee designs such awards as long-term incentives. The terms and conditions of currently outstanding awards include:

· NQSO grants vest one-third (1/3) on each anniversary of the grant date. As such, NQSO grants become fully vested over a three-year period. NQSO grants expire on the tenth anniversary of the grant date. The Company does not pay dividends on shares underlying NQSO grants until the optionee exercises the option and the shares are outstanding on a dividend record date.

· RPS awards vest three years following the grant date, only if corporate performance objectives are achieved over the three-year period. The Company does not pay dividends on RPS shares until vesting occurs and shares awarded become outstanding on a dividend record date.

Compensation for the Chairman, President & CEO

Mr. Payne performs two functions for the Company. These two functions tend to be compensated separately at similarly sized banking institutions. Mr. Payne serves as Chairman of the Board and CEO with responsibilities including oversight of the organization and external strategic initiatives. Mr. Payne also serves as President and CEO with responsibilities including daily management of internal operations. Mr. Payne’s total compensation reflects these broad responsibilities. Consistent with the overall compensation philosophy for senior executives, Mr. Payne’s compensation has a greater amount of pay at risk through incentives than through base salary. Since Mr. Payne is compensated as an executive, he is not eligible to receive compensation as a Director.

As noted on page 30 of the Proxy under the Pension Benefits Table, during 1997 the Company entered into a nonqualified pension agreement (“Pension Agreement”) with Mr. Payne in consideration of Mr. Payne’s agreement that RPS granted in 1995, 1996 and 1997 would be cancelled.⁽¹⁾ In entering the Pension Agreement, the Board of Directors considered the following:

· Mr. Payne had a significant beneficial interest in Westamerica Bancorporation common stock, which was more than adequate to continue to provide motivation for Mr. Payne to continue managing the Company in the best interests of shareholders.

· In 1997, the Company had consummated its largest acquisition, with significant total asset growth of approximately 51 percent. One of the Board’s objectives was to provide a compensation mechanism

⁽¹⁾ The value of the surrendered RPS shares and the Pension Agreement were considered equivalent based on actuarial assumptions.

19

providing retention features for Mr. Payne. Retention of Mr. Payne as President and CEO was desired following the Company’s significant growth. The RPS shares surrendered for the Pension Agreement were scheduled to vest on dates in 1998, 1999 and 2000, while the Pension Agreement was not fully vested until December 31, 2002. Additionally, the 20-year certain pension provided under the Pension Agreement was to commence upon Mr. Payne’s attainment of age 55. Mr. Payne was age 42 at the time of entering the Pension Agreement.

Compensation Awarded to Named Executive Officers

Base salaries for participants in the executive compensation program are generally limited to foster an environment where incentive compensation motivates and rewards corporate, divisional, and individual performance. As such, base pay increases are generally infrequent and limited to “control points” assigned to each position. The non-equity cash incentive formula has the following components:

In structuring performance goals for the named executive officers, the Compensation Committee emphasizes goals, which if achieved, will benefit the overall Company. As such, senior management level positions have high relative weighting on corporate objectives, and divisional leadership positions also have significant weighting on divisional objectives. The “target” cash incentive and the weighting of goals for the named executive officers for 2016 performance were as follows:

	“Target”		Goal Weighting
	Cash
	Incentive		Corporate			Divisional			Individual
Mr. Payne	$	371,000		80	%		–			20	%
Mr. Thorson		105,000		55	%		25	%		20	%
Mr. Robinson		82,500		50	%		40	%		10	%
Mr. Hansen		73,900		55	%		25	%		20	%
Mr. Rizzardi		60,500		55	%		35	%		10	%

The Compensation Committee establishes corporate goals with the intent to balance current profitability with long-term stability of the Company and its future earnings potential. The 2016 corporate performance goals related to current year “profitability” included return on equity, return on assets and diluted earnings per share. The performance goals designed to maintain the long-term stability of the Company include “quality” and “control” components. The “quality” measures include loan portfolio quality measures (originated classified loans and other real estate owned, originated non-performing loans and originated other real estate owned, and net loan losses to average originated loans) and service quality measures (external service quality to customers and internal service quality of support departments and branches). The “control” measures include non-interest expense to revenues (efficiency ratio), the level of non-interest expenses, and internal audit results. By maintaining both current year “profitability” goals and longer-term “quality” and “control” goals, Management has a disincentive to maximize current earnings at the expense of longer-term results.

20

For 2016, the Compensation Committee expected nominal economic growth with a high level of uncertainty, particularly in regard to the interest rate environment. As a result, the Committee reserved the ability to exercise a certain degree of judgment in adjusting target goals based on the resulting operating environment.

The Compensation Committee determined the 2016 operating environment was generally characterized as follows:

· Growth in the United States’ economy was positive, but generally below potential;

· Inflation remained below targets established by the Federal Open Market Committee in spite of continuing high levels of monetary policy accommodation and improving employment conditions;

· Interest rates were volatile, with longer-term rates declining at times during the year; the Federal Open Market Committee did not change the federal funds rate until December 2016;

· Interest rates on loans and investment securities remain relatively low compared to interest rates which would exist with moderated monetary policies and economic conditions. Competitors offered loan interest rates well below the yields required for the Company to deliver satisfactory financial results throughout a full business cycle;

· Real estate values in the Company’s metropolitan geographies appeared to increase to levels above those which could be sustained by prevailing economic conditions; and

· Regulations imposed on banks continued to pressure compliance costs, revenue opportunities, and increased operational risks.

The Compensation Committee considered Management’s response to the current operating environment including:

· Management positioned the Company’s loans, investment securities and deposits, in anticipation of rising interest rates;

· Management consistently maintained conservative loan underwriting practices to appropriately manage the Company’s exposure to credit risk;

· Management increased the value of the Company’s deposit base by increasing checking and savings deposits and reducing time deposits;

· Management lowered operating costs to offset market interest rate pressure on revenues;

· Management maintained high levels of customer service; and

· Management prudently managed capital enabling the Company to continue delivering increasing annual levels of dividends per share and position the Company for growth opportunities.

The Compensation Committee chose to make adjustments to actual results to take into account the impact of the operating environment. Adjusted actual results against “target” performance goals were:

	Performance	Adjusted Actual
	“Target”	Results
Profitability Goals:
Return on average shareholders’ equity	11.2%	11.3%
Return on average assets	1.14%	1.13%
Diluted earnings per share	$2.26	$2.33
Quality Goals:
Classified originated loans and other real estate owned	$52 million	$31 million
Non-performing originated loans and other real estate owned	$11.0 million	$6.6 million
Net loan losses to average originated loans	0.15%	0.10%
Service quality	Improving	Improving

21

Control Goals:
Non-interest expense to revenues (efficiency ratio)	53.3%	52.1%
Non-interest expenses	$103.5 million	$101.2 million
Below satisfactory internal audits	none	none

In reviewing the operating environment, Management’s response to the operating environment, and adjusted results compared to “target” performance goals, the Compensation Committee determined corporate performance to be 110.1% of target goals.

As described above, divisional and individual goals are used in conjunction with corporate performance goals to determine cash bonus awards.

In addition to daily management responsibilities, Mr. Payne’s individual goals included:

· Manage the Company to achievement of financial goals without compromising on credit quality standards as to underwriting or to pricing;

· Prepare the Company’s financial condition for a period of rising interest rates;

· Control operating costs by managing to a neutral position relative to 2015;

· Maintain a strong internal control environment and risk management practices;

· Satisfactory regulatory examinations and external and internal audit results;

· Pursue mergers and acquisitions; and

· Personnel development within divisional and middle management positions.

Based on individual performance against these goals, the Committee exercised its discretion and assigned Mr. Payne a composite corporate and individual performance level of 61%.

In addition to routine on-going divisional responsibilities, Mr. Thorson managed the Finance Division toward functional goals, which included:

· Manage the level of earning assets to achieve desired financial results;

· Manage the investment securities portfolio in anticipation of rising interest rates: maximize the possible yield while meeting duration objectives and maintaining high credit quality;

· Develop personnel and operating systems to foster business continuity;

· Manage the process of adopting new accounting standards;

· Manage the Trust Department toward achieving fee growth goals, maintain satisfactory audit results, and personnel development activities; and

· Satisfactory regulatory examinations, external audits, and internal audits with all areas of responsibility.

Based on the Finance Division’s results, the Committee determined divisional performance to be 113%.

In addition to daily management responsibilities, Mr. Thorson’s individual goals included:

· Provide financial management support to potential merger and acquisitions activities;

· Support cross-divisional regulatory compliance initiatives; and

· Solicit shareholder votes which support the Board of Directors proxy recommendations.

Based on individual performance against these goals, the Committee determined Mr. Thorson’s individual performance to be 138%. In considering all elements of performance, the Committee exercised its discretion and assigned Mr. Thorson a composite corporate, divisional and individual performance level of 143%.

In addition to routine on-going divisional responsibilities, Mr. Robinson managed the Banking Division toward

22

functional goals, which included:

· Regional sales management responsibilities;

· Achievement of deposit goals;

· Sales management of non-interest income generated through the branch system; and

· Hiring of sales personnel.

Based on the Banking Division’s results, the Committee determined divisional performance to be 100%.

In addition to daily management responsibilities, Mr. Robinson’s individual goals included:

· Coach and mentor subordinates to higher levels of performance;

· Outbound customer calling activities;

· Leadership in the career development initiatives; and

· Management of service quality standards within the Banking Division.

Based on individual performance against these goals, the Committee determined Mr. Robinson’s individual performance to be 138%. As a result, Mr. Robinson’s composite corporate, divisional and individual performance level was 109%. In considering all elements of performance, the Committee exercised its discretion and assigned Mr. Robinson a composite corporate, divisional and individual performance level of 133%.

In addition to routine on-going divisional responsibilities, Mr. Hansen managed the Operations and Systems Division toward functional goals, which included:

· Maintain and improve customer service quality;

· Meet or exceed non-interest expense goals without compromising service quality and internal controls;

· Satisfactory risk management as measured by the results of internal, third-party and regulatory examinations;

· Meet personnel development objectives;

· Management and satisfactory completion of information technology projects; and

· Successful transition of third-party vendor relationship.

Based on the Operations and Systems Division’s results, the Committee determined divisional performance to be 118%.

In addition to daily management responsibilities, Mr. Hansen’s individual goals included:

· Managerial oversight of marketing and merchant processing services functions;

· Management of divisional internal controls and risks;

· Satisfactory audit results; and

· Personnel management objectives.

Based on individual performance against these goals, the Committee determined Mr. Hansen’s individual performance to be 138%. As a result, Mr. Hansen’s composite corporate, divisional and individual performance level was 117%.

In addition to routine on-going divisional responsibilities, Mr. Rizzardi managed the Credit Division toward functional goals, which included:

· Properly underwriting loan facilities and maintain high quality loan underwriting standards;

· Maintain credit quality as measured by net loan charge-offs, levels of non-performing loan and other real estate owned, classified and criticized loan volumes, and consumer and commercial loan delinquencies;

· Direct supervision within commercial loan underwriting offices;

23

· Update credit policies and procedures;

· Delivery of superior customer service; and

· Satisfactory regulatory examination results.

Based on the Credit Division’s results, the Committee determined divisional performance to be 100%.

In addition to daily management responsibilities, Mr. Rizzardi’s individual goals included:

· Enhancement of Board and management reporting functions; and

· Increase participation in development of customer relationships.

Based on individual performance against these goals, the Committee determined Mr. Rizzardi’s individual performance to be 75%. As a result, Mr. Rizzardi’s composite corporate, divisional and individual performance level was 103%.

Based on the above described performance against objectives, the Committee determined cash incentive awards as follows:

	“Target”			Composite Corporate				Cash
	Cash		X	Divisional and Individual			=	Incentive
	Incentive			Performance Level				Award
Mr. Payne	$	371,000			61	%		$	225,000
Mr. Thorson		105,000			143	%			150,200
Mr. Robinson		82,500			133	%			109,800
Mr. Hansen		73,900			117	%			86,700
Mr. Rizzardi		60,500			103	%			62,300

The size of stock grants is determined by corporate performance using stated formulas. The formulas used to determine “target” NQSO and RPS grant sizes adjust for changes in the underlying value of one share of Westamerica Bancorporation common stock. For achievement of corporate performance in 2016, the following stock grants were awarded in January 2017:

	“Target”							Nonqualified
	Nonqualified			Corporate				Stock
	Stock Option		X	Performance			=	Option
	Grant			Level				Award
Mr. Payne		–			110.1	%			–
Mr. Thorson		19,700			110.1	%			21,700
Mr. Robinson		19,800			110.1	%			21,800
Mr. Hansen		17,600			110.1	%			19,400
Mr. Rizzardi		15,900			110.1	%			17,500

	“Target”			Corporate
	RPS		X	Performance			=	RPS
	Grant			Level				Award
Mr. Payne		–			110.1	%			–
Mr. Thorson		1,950			110.1	%			2,150
Mr. Robinson		1,970			110.1	%			2,170
Mr. Hansen		1,760			110.1	%			1,940
Mr. Rizzardi		1,590			110.1	%			1,750

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved over the three-year period. In January 2017, the Compensation Committee evaluated whether the three year corporate performance objectives were met for RPS awards granted in January 2014. The performance objectives for the RPS granted in January 2014 included:

· 3 year cumulative diluted earnings per share (EPS);

· 3 year average of annual return on average total assets (ROA);

· 3 year average of annual return on average shareholders’ equity relative to industry average ROE (ROE differential);

· Ending originated non-performing assets to total originated assets (NPA); and

· Efficiency ratio over three years.

The RPS would vest if any one of the following performance results were achieved:

· 4 of 5 objectives reaching “threshold” performance level;

· 3 of 5 objectives reaching “target” performance level; or

· 2 of 5 objectives reaching “outstanding” performance level.

The goals and achieved results were:

	Threshold			Target			Outstanding			Result
EPS	$	7.00		$	7.05		$	7.15			Outstanding
ROA		1.21	%		1.23	%		1.27	%		Threshold
ROE differential		1.85	%		2.00	%		2.30	%		Outstanding
NPA		0.50	%		0.35	%		0.25	%		Outstanding
Efficiency Ratio		56.00	%		53.00	%		50.00	%		Target

With five of the goals achieving the “threshold” performance level or better, the Compensation Committee determined the RPS shares awarded in 2014 vested upon achievement of three year goals.

Nonqualified Deferred Compensation Programs

The Company maintains nonqualified deferred compensation programs to provide senior and mid-level executives the ability to defer compensation in excess of the annual limits imposed on the Company’s ESOP plan. The Company believes these tax deferral programs enhance loyalty and motivate retention of executives. These programs allow executives to defer cash pay and RPS shares upon vesting. The programs also allow Directors to defer Director fees.

· Cash pay deferred in the program accumulates in accounts in the names of the participating Directors and executives. The Company credits the balance of these accounts with interest using an interest rate that approximates the crediting rate on corporate-owned life insurance policies, under which Directors and executives are the named insured. Deferrals and interest credits represent general obligations of the Company.

· The common stock the Company issues to executives upon the vesting of RPS grants may be deferred into the program and deposited into a “Rabbi Trust.” Since these shares are outstanding shares of the Company’s common stock, the Company pays dividends on these shares at the same rate paid to all shareholders. The shares held in the “Rabbi Trust” are subject to claims by the Company’s creditors.

Employment Contracts

None of the executives named in the accompanying tables have employment contracts with the Company.

Compensation in the Event of a Change in Control

The banking industry has significant merger and acquisition activity. To promote retention of senior executives,

25

unvested NQSO and RPS grants contain a “change in control” provision, which trigger full vesting upon a change in control. The Compensation Committee determined these provisions were appropriate in order to retain executives to continue managing the Company after any “change in control” was announced through its ultimate consummation. Since none of the named executive officers have entered employment contracts with the Company, they serve in an “at-will” capacity and could terminate their employment at any time. The Compensation Committee felt it would be in the best interests of shareholders to have a retention mechanism in place to provide continuity of management during a “change in control” process. Further, the Committee expects the named executive officers would be terminated by an acquiring institution rather than retained in a similar functional capacity.

The Company also maintains a Severance Payment Plan covering all employees to promote employee retention. The Severance Payment Plan provides salary continuation benefits for employees in the event of a “change in control.” The amount of salary continuation benefits is based on years of service and corporate title, but in no event exceed the equivalent of one times annual salary. All named executive officers are eligible for one year’s salary under the plan.

Other

Internal Revenue Code (“IRC”) Section 162(m) places a limit on the amount of compensation that may be deducted by the Company in any year with respect to certain of the Company’s highest-paid executives. Certain “performance-based compensation” is not counted toward this limit. The Company intends generally to qualify compensation paid to executive officers for deductibility under the IRC, including Section 162(m), but reserves the right to pay compensation that is not deductible.

Pension Benefits For Fiscal Year 2016

Name	Plan Name	Present Value of Accumulated Benefit	Payments during Last Fiscal Year
David L. Payne	Non-Qualified Pension Agreement	$5,140,075	$511,950

During 1997, the Company entered into a nonqualified pension agreement with Mr. Payne in consideration of Mr. Payne’s agreement that RPS awards granted in 1995, 1996 and 1997 would be cancelled. In January 2000, the Compensation Committee, based on the Company’s achievement of certain performance goals which had first been established for Mr. Payne’s 1995, 1996 and 1997 RPS awards, determined Mr. Payne’s annual pension would be $511,950. The pension commenced in 2010 and will be paid to Mr. Payne for 20 years.

The discount rate used to determine the present value is 4.10%, as used by the Company in determining benefit obligations for its post-employment retirement benefits as of December 31, 2016. The obligation is an unfunded general obligation of the Company.

⁽¹⁾ No RPS shares were deferred upon vesting in 2016. Non-equity incentive plan compensation deferred in 2016 was earned in 2015 and disclosed as compensation in the Summary Compensation Table for 2015 and is therefore excluded from the Summary Compensation Table for Fiscal Year 2016.

⁽²⁾ Includes change in value of deferred RPS shares, dividends earned on deferred RPS shares, and interest earned on deferred cash compensation. The amounts included in the Summary Compensation Table for Fiscal Year 2016 on page 24 are as follows: Messrs. Thorson - $42,431; Robinson - $36,094; Hansen - $28,092.

⁽³⁾ Includes dividends paid on deferred RPS shares.

Under the Westamerica Bancorporation and Subsidiaries Deferred Compensation Plan (the “Deferred Compensation Plan”), Directors and Officers may defer up to 100% of their Director’s compensation, salary and/or non-equity incentive compensation (cash bonus) into a non-qualified, unfunded deferred compensation program. The interest rate paid during 2016 was 5.45%. The interest rate may be changed annually. Interest is compounded semi-monthly. Participants choose in advance from the following distribution commencement dates: termination of employment, January 1 following termination of employment, or a specific date at least five years from date of deferral. Payment is made in a lump sum unless the participant chooses a four year, five year or ten year annual installment.

Under the Westamerica Bancorporation Deferral Plan, 100% of vested RPS grants may be deferred. Dividends paid on such issued and outstanding shares are paid in cash to the deferral participants, and are paid at the same rate as is paid to all other shareholders. The distribution of deferred RPS shares occurs at least two years after deferral, one month following termination, or the January 1 immediately following termination as elected by the participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions that are made upon termination of employment may not start earlier than six months after the date of termination.

Potential Payments Upon Termination or Change in Control

Payments to be made to the named executive officers in the event of termination of employment or change in control are described below.

Termination

Vested NQSOs may be exercised within 90 days of termination and within one year of death or disability. RPS shares vest if the Compensation Committee determines performance goals are met. Terminated employees will receive vested RPS shares if the settlement date of the RPS grant occurs within 90 days of termination. Employees separating from service due to death, disability or retirement are eligible to receive a pro rata portion of granted RPS shares if the Compensation Committee determines that the performance goals are likely to be met for the grant period. The pro rata basis is determined by the number of full years of the vesting period completed before date of death, disability or retirement.

Deferred compensation account balances are distributed on January 1 following termination, or a specific date at least five years from the date of deferral in the form of annual payments over four years. Payment may also be made in a lump sum or in annual payments for five or 10 years as elected by the participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions that are made upon termination of employment may not start earlier than six months after the date of termination.

Change in Control

A change in control is defined under the 2012 Amended Plan as shareholder approval of a dissolution or liquidation of the Company or a sale of substantially all of the Company’s assets to another company, or a tender offer for 5% or more of the Company’s outstanding common stock or a merger in which the Company’s shareholders before the merger hold less than 50% of the voting power of the surviving company after the merger.

In the event of a change in control, unvested NQSOs and RPS shares immediately vest. The value of in-the-money options and RPS shares subject to accelerated vesting for each of the named executive officers is as follows: Messrs. Payne: $0; Thorson: $1,505,133; Robinson: $1,513,989; Hansen: $1,355,316; and Rizzardi⁽²⁾ $1,220,858. The value is computed by multiplying the difference between the market value on December 30, 2016, the last business day of 2016, and the exercise price of each option by the number of shares subject to accelerated vesting.

⁽²⁾ Mr. Rizzardi’s compensation is subject to garnishments and liens pursuant to certain domestic relations orders.

31

Under the Company’s Severance Payment Plan, executive officers receive six week’s pay for every year or partial year of service up to one year’s base salary (see Summary Compensation Table for Fiscal Year 2016 for annual base salary for all named executive officers). All named executive officers have met the service requirement for one year’s base salary. Severance pay is paid in a lump sum or on a semi-monthly basis at the discretion of the Company. The Severance Payment Plan is subject to Section 409A of the Internal Revenue Code.

Certain Relationships and Related Party Transactions

In accordance with the Audit Committee Charter, the Audit Committee is responsible for reviewing and approving or disapproving 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 Conduct and Ethics provides rules that restrict transactions with affiliated persons.

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of the Company in the ordinary course of business. With the exception of the Company’s Employee Loan Program, all outstanding loans and commitments included in such transactions were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company, did not involve more than a normal risk of collectability, and did not present other favorable features. As part of the Employee Loan Program, all employees, including executive officers, are eligible to receive mortgage loans with interest rates one percent (1%) below Westamerica Bank’s prevailing interest rate at the time of loan origination. Westamerica Bank makes all loans to executive officers under the Employee Loan Program in compliance with the applicable restrictions of Section 22(h) of the Federal Reserve Act. Messrs. Payne, Thorson, and Hansen have mortgage loans through this Program. The largest aggregate amount of principal during 2016 was $404,058, $282,451, and $224,274, respectively. The principal amount outstanding at December 31, 2016 was $384,877, $267,611, and $214,079, respectively. The amount of principal paid during 2016 was $19,181, $14,840, and $10,195, respectively. The amount of interest paid during 2016 was $8,513, $5,519, and $4,871, respectively. The rate of interest payable on the loan is 2.375%, 2.375%, and 2.50%, respectively.

PROPOSAL 2 – APPROVE A NON-BINDING ADVISORY VOTE ON THE COMPEN-SATION OF OUR NAMED EXECUTIVE OFFICERS

Background

The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires that shareholders cast a non-binding advisory vote on the executive compensation paid to the executive officers listed in the Summary Compensation Table (a so-called “say on pay” vote) as well as an advisory vote with respect to whether future say on pay votes will be held every one, two or three years. The result of the shareholder vote on the proposal to determine the frequency of future say on pay proposals was that shareholders should review executive compensation annually. Therefore, Proposal 2 requests that shareholders again approve the compensation paid to our named executive officers. Last year 95% of the shares voting on this proposal voted to support our Corporation’s executive compensation strategy. The proposal to determine how often the say on pay proposal should be voted on by shareholders will again be brought to a shareholder vote in 2017, six years after the first frequency vote.

We believe that our compensation policies and procedures are centered on a pay-for-performance culture and are strongly aligned with the long-term interests of our shareholders. Our incentive compensation plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, and restricted performance shares. The Summary Compensation Table shows very stable base salaries indicative of our greater emphasis on performance-based stock and non-stock awards. Our stock and option awards are based on a minimum achievement

32

of meeting the “threshold” level for each pre-established objective. Both awards have a three-year vesting period. Our annual incentive plan incorporates at least four financial and/or strategic performance metrics in order to properly balance risk with the incentives to drive our key annual financial and/or strategic initiatives; in addition, the annual incentive program incorporates a 150% maximum payout to further manage risk and the possibility of excessive payments.

In 2003, shareholders approved the Company’s 2003 Amended Plan to include the following changes:

· Disallowing re-pricing stock options for poor stock performance;

· Limiting the number of shares that may be awarded; and

· Requiring the Compensation Committee to meet the definition of independence to enable any award intended to qualify as “performance-based compensation” to meet Section 162(m) of the Internal Revenue Code.

In 2009, shareholders re-approved the performance criteria for performance-based awards under the 2003 Amended Plan.

In 2012, shareholders approved the Company’s 2012 Amended and Restated Stock Option Plan of 1995. The 2012 Amended Plan includes the following changes:

· Reduced the number of shares available for future issuance from 4,307,593 to 1,500,000 (plus shares that become available if awards under prior plans expire unexercised or are cancelled, forfeited or terminated before being exercised; and

· Extended the term of the 2012 Amended Plan to April 26, 2022 from April 24, 2013.

Vote Required

The “say on pay” proposal gives you as a shareholder the opportunity to endorse or not endorse our executive pay program through the following resolution:

“Resolved, that the shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, which disclosure includes the compensation discussion and analysis, the compensation tables and any related footnotes and narratives in the Company’s proxy statement for the Annual Meeting of Shareholders.”

Because your vote is advisory, it will not be binding on the Board or create or imply any additional fiduciary duty by the Board. However, the Compensation Committee may take into account the outcome of the vote when considering future executive compensation arrangements.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A

VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE SECURITIES AND EXCHANGE COMMISSION

33

PROPOSAL 3 – RE-APPROVE THE PERFORMANCE CRITERIA FOR INCENTIVE COMPENSATION

Compensation of an executive in excess of $1,000,000 per year is not deductible for tax purposes unless it qualifies as "performance-based compensation" under Code Section 162(m), one requirement is that a corporation's shareholders approve the "material terms of the performance goals" under which performance-based compensation is to be paid, at least every five (5) years if (as is the case under the 2012 Amended Plan) the plan's committee has authority to change the specific targets under the shareholder approved performance goal(s). Under Code Section 162(m), the material terms of performance goal (“Material Terms”) requiring shareholder approval are:

· The employees eligible to receive the performance-based compensation;

· A description of the business criteria on which each performance goal is based; and

· Either the formula used to calculate the performance-based compensation, or, alternatively, the maximum amount of such compensation that could be awarded or paid to any eligible employee if the applicable performance goals are met.

Participant Eligibility

Our executives, other employees and directors are eligible to receive awards under the 2012 Amended Plan.

Performance Condition Business Criteria and Formulas

The Compensation Committee establishes corporate goals with the intent to balance current profitability with long-term stability of the Company and its future earnings potential. The 2016 corporate performance goals related to current year “profitability” included return on equity, return on assets and diluted earnings per share. The performance goals designed to maintain the long-term stability of the Company include “quality” and “control” components. The “quality” measures include loan portfolio quality measures (originated classified loans and other real estate owned, originated non-performing loans and originated other real estate owned, and net loan losses to average originated loans) and service quality measures (external service quality to customers and internal service quality of support departments and branches). The “control” measures include non-interest expense to revenues (efficiency ratio), the level of non-interest expenses, and internal audit results. By maintaining both current year “profitability” goals and longer-term “quality” and “control” goals, Management has a disincentive to maximize current earnings at the expense of longer-term results.

In addition to establishing corporate performance objectives, the Compensation Committee also establishes individual goals for executives, the CEO recommends divisional and individual performance objectives to the Compensation Committee, which considers, discusses, adjusts as necessary, and adopts such performance objectives.

Upon the closure of each calendar year, the Compensation Committee reviews corporate, divisional, and individual performance against the performance objectives for the year just completed. After thorough review and deliberation, the Compensation Committee determines the recommended amount of individual non-equity cash incentives and stock-based incentive awards. The Compensation Committee reports such incentives to the Board of Directors. Meetings of the Compensation Committee and Board of Directors routinely occur in January, immediately following the closure of the calendar year for which performance is measured for incentive compensation.

The 2012 Amended Plan and other compensation policies specify performance conditions that the Committee may include in awards intended to qualify as performance-based compensation under Code Section 162(m). These policies and conditions are described more fully above under “Compensation discussion and Analysis.” These performance criteria include the following target objectives:

· Incentive compensation (annual non-equity cash incentives and long-term stock grants) is based on measurement of performance against pre-established objective measurable goals. Specific criteria for each

34

objective are established for “threshold,” “target,” and “outstanding” performance. On any one measure, performance below “threshold” results in no credit for that objective. “Threshold” performance results in 75% achievement, “target” performance results in 100% achievement, and “outstanding” performance results in 150% achievement. The performance achievement level determines the size of incentive compensation awards;

· Long-term incentive stock grants will be awarded to senior management if the corporate performance level is rated “threshold” or better.

· Restricted performance shares (“RPS”) represent awards of Westamerica Bancorporation’s common stock subject to achievement of performance objectives established by the Compensation Committee. The criteria for these objectives include:

– Earnings;

– Diluted earnings per share;

– Revenue and revenue per diluted share, expenses;

– Share price;

– Return on equity;

– Return on equity relative to the average return on equity for similarly sized institutions;

– Return on assets;

– Return on assets relative to the average return on assets for similarly sized institutions,

– Efficiency ratio (operating expenses divided by operating revenues);

– Net loan losses as a percentage of average loans outstanding;

– Non-performing assets; and

– Non-performing assets as a percentage of total assets.

· RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved over the three-year period. The performance objectives for the RPS granted in January 2014 and potentially vesting in 2017 include:

– 3 year cumulative diluted earnings per share (EPS);

– 3 year average of annual return on average total assets (ROA);

– 3 year average of annual return on average shareholders’ equity relative to industry average ROE (ROE differential);

– Ending originated non-performing assets to total originated assets (NPA); and

– Efficiency ratio over three years.

The RPS would only vest if any one of the following performance results were achieved: 3 year cumulative diluted earnings per share (EPS);

– 4 of 5 objectives reaching “threshold” performance level;

– 3 of 5 objectives reaching “target” performance level; or

– 2 of 5 objectives reaching “outstanding” performance level.

If this Proposal 3 is approved by shareholders, then each of the above performance criteria would be approved for use (until the earlier of our annual meeting of shareholders in 2022 or the expiration of the 2012 Amended Plan), at the Committee's discretion, in awards that are intended to qualify as performance-based compensation under Code Section 162(m). While the Committee intends to include one or more of the foregoing performance conditions in awards of restricted stock and stock units made under the 2012 Amended Plan, due to the complexities of Section 162(m) and technical requirements related thereto that may change from time to time, we can provide no assurance that such awards would qualify as "performance-based compensation" such that the Company would be able to claim a tax deduction for such awards without limitation under Code Section 162(m). Certain other awards, such as stock options, may also qualify as performance-based compensation under Code Section 162(m) without including of any of the above performance conditions.

35

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RE-APPROVAL OF THE PERFORMANCE CRITERIA FOR INCENTIVE COMPENSATION, AS DISCLOSED ABOVE AND ELSEWHERE IN THIS PROXY STATEMENT

PROPOSAL 4 – APPROVE A NON-BINDING ADVISORY VOTE ON THE FREQUENCY OF THE ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Background

In addition to the non-binding advisory vote on executive compensation, the Dodd-Frank Act required the Securities and Exchange Commission to amend its rules to require that a non-binding advisory proposal be submitted to shareholders once every six years that would determine the frequency of the advisory vote on the compensation paid to the Corporation’s named executive officers as seen in Proposal 2 above.

After careful consideration of this proposal, our Board has determined that continuing an advisory vote on executive compensation annually is most appropriate for the Company, and therefore our Board recommends that you vote for a one-year interval for the advisory vote on executive compensation.

In formulation of its recommendation, our Board considered that an advisory vote on executive compensation every year will allow our shareholders to provide us with their direct input on our compensation philosophy, policies and practices and disclosed in the proxy statement every year. Setting a one year period for holding this shareholder vote will enhance shareholder communication by providing a clear, simple means for the Company to obtain information on investor sentiment about our executive compensation philosophy.

You may cast your vote on your preferred voting frequency by choosing the option of one year, two years, three years or abstain from voting when you vote.

The choice of frequency that receives the highest number of “FOR” votes will be considered the advisory vote of the shareholders. Abstentions and broker non-votes will not count as votes cast for any frequency choice, and will have no direct affect on the outcome of this proposal. A signed, uninstructed proxy will be voted for “EVERY ONE YEAR”. However, because this vote is advisory and not binding on the Board in any way, the Board may decide that it is in the best interest of our shareholders and the Company to hold an advisory vote on executive compensation more or less frequently than the option approved by shareholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR “EVERY ONE YEAR”

PROPOSAL 5 – RATIFY SELECTION OF INDEPENDENT AUDITOR

Ratify Selection of Independent Auditor

Action by the shareholders is not required by law in the appointment of independent auditors, but their appointment is submitted by the Audit Committee and the Board of Directors in order to give the shareholders an opportunity to present their views. If the proposal is approved, the Audit Committee, in its discretion, may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders. If the proposal to ratify the selection of Crowe Horwath LLP as the Company’s independent auditors is rejected by the shareholders, then the Audit Committee will reconsider its choice of independent auditors. A representative of Crowe Horwath LLP is expected to be present at

36

the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Audit Fees

The aggregate fees billed to the Company by Crowe Horwath LLP with respect to services performed for fiscal 2016 and 2015 are as follows:

	2016		2015
Audit Fees(1)	$	510,000	$	510,000
Audit related fees(2)		34,450		33,875
Tax fees(3)		39,000		38,050
All other fees		-		-
Total	$	583,450	$	581,925

⁽¹⁾ Audit fees consisted of fees billed by Crowe Horwath LLP for professional services rendered for the audit of the Company’s consolidated financial statements, reviews of the consolidated financial statements included in the Company’s quarterly reports on Form 10-Q, and the audit of the Company’s internal controls over financial reporting. The audit fees also relate to services such as consents and audits of mortgage banking subsidiaries.

⁽²⁾ Audit-related fees consisted of fees billed by Crowe Horwath LLP for audits of certain employee benefits plans.

⁽³⁾ Tax fees consisted of fees billed by Crowe Horwath LLP for the compilation and review of the Company’s tax returns.

Preapproval Policies and Procedures

The Audit Committee is responsible for the appointment, compensation, retention and oversight of the work of any public accounting firm engaged by the Company for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Company. Any accounting firm appointed by the Company reports directly to the Audit Committee.

The Audit Committee must preapprove all auditing services and permitted non-audit services by its independent auditors and the fees to be paid by the Company for these services, except for those fees qualifying for the “de minimis exception” which provides that the preapproval requirement for certain non-audit services may be waived if certain express standards and requirements are satisfied prior to completion of the audit under certain conditions. This exception requires that the aggregate amount of all such services provided constitutes no more than five percent of the total amount of revenue paid to the audit firm by the Company during the fiscal year in which the services are provided. This exception also requires that at the time of the engagement, the Company did not recognize such services to be non-audit services, and such services are promptly brought to the attention of the Audit Committee and approved prior to the completion of the audit by the Audit Committee. During fiscal year 2016, there were no non-audit services that were provided using this exception.

The Audit Committee may delegate to one or more members of the Audit Committee the authority to grant preapprovals of non-audit services and fees. In such event, the decisions of the member or members of the Committee regarding preapprovals are presented to the full Audit Committee at its next meeting. The Audit Committee preapproved 100% of all services performed on behalf of the Company by Crowe Horwath LLP during fiscal year 2016.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE SELECTION OF CROWE HORWATH LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

AUDIT COMMITTEE REPORT

The material in this report is not soliciting material and is not deemed filed with the SEC. It is not incorporated by reference in any of the Company’s filings under the Securities Act of 1933 or the Exchange Act, whether made in the past or in the future even if any of those filings contain any general incorporation language.

The Audit Committee is composed of four Directors who are neither officers nor employees of the Company, and who meet the NASDAQ independence requirements for Audit Committee members. The Audit Committee selects, appoints and retains the Company’s independent auditors and is responsible for their compensation and oversight.

In performing its functions, the Audit Committee 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 auditors. The auditors express an opinion on the conformity of the Company’s annual financial statements to generally accepted accounting principles. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited consolidated financial statements for the fiscal year 2016 and discussed them with Management and with Crowe Horwath, LLP, the Corporation’s independent auditors.

Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles. Management also represented that it performed an assessment of the effectiveness of internal control over financial reporting as of December 31, 2016, and that internal control over financial reporting was effective. The independent auditor discussed with the Audit Committee matters required to be discussed by Auditing Standard No. 16 (Communications with Audit Committees), including certain matters related to the conduct of an audit and to obtain certain information from the Audit Committee relevant to the audit.

The auditors also provided to the Audit Committee the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). The Audit Committee discussed with auditors the firm’s independence.

Based on the Audit Committee’s discussion with Management and the independent auditors, the Audit Committee’s review of the representations of Management and the Report of the Independent Auditors to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the SEC.

PROPOSAL 6 – REQUIRE INDEPENDENT BOARD CHAIRMAN

The Board unanimously recommends you vote “AGAINST” the shareholder proposal set forth below.

Shareholder Proposal

Gerald R. Armstrong, 621 Seventeenth Street, Suite 2000, Denver, Colorado 80293-2001, (303) 355-1199, the owner of 3,594 shares of our common stock, has advised us that he plans to introduce the following resolution at the

38

annual meeting. In accordance with rules of the SEC, the text of the proponent’s resolution and supporting statement is printed verbatim from his submission.

RESOLUTION

That the shareholders of WESTAMERICA BANCORPORATION request its Board of Directors to adopt a policy, and amend the by-laws as necessary, to require the Chairman of the Board of Directors be an independent member of the Board of Directors.

This policy should not be implemented to violate any contractual obligation and should specify: (a) how to select a new “independent” chairman if the current chairman ceases to be independent during the time between annual meetings of shareholders; and, (b) that compliance is excused if no independent director is available and willing to serve as Chairman.

The unedited reasons given by the proponent for the resolution are as follows:

WESTAMERICA BANCORPORATION and WELLS FARGO & COMPANY opposed this proposal last year.

In the fall of 2016 Wells Fargo & Company admitted its several problems, it abandoned the dual role of one person serving as its Chairman of the Board while being Chief Executive Officer and appointed an “independent” Chairman and “independent” Vice-Chairman of the Board. Obviously, its Board finally realized the seriousness of the issues and the impact of paying $210,000,000 in fines. More recently, it increased high-end estimates of reasonably possible potential litigation losses to $1,700,000,000.

The proponent is a professional investor owning shares in Westamerica since 1989 and shares in most of the banks acquired by Westamerica.

As a shareholder, I am concerned about Westamerica’s wilting performance, which, after analysis, I believe to be caused by the entrenchment of David Payne as Chairman, Executive Officer, and President and members of the Board of Directors whose average tenure was 28.5 years and an average age of 76 years (based on the proxy statement for the 2016 annual meeting).

Let’s look at some numbers of the “Five Year Return Performance” graphs contained in 10-K reports of Westamerica and two nearby holding companies. (Cumulative Return on investment and re-investment of all dividends):

	12/31/2010		12/31/2015
Westamerica Bancorporation	$	100.00	$	98.91
Bank of Marin Bancorp		100.00		167.00
FNB Bancorp (South San Francisco)		100.00		419.92

The greatest difference in the governance practices of Bank of Marin Bancorp and FNB Bancorp is that each has an “independent” chairman of it Board of Directors while Westamerica has one person, David Payne, serving in both capacities and as President, he accounts only to himself as Chairman which is why Westamerica is the underachiever.

Moreover, I believe Mr. Payne’s dual positions at Westamerica are only parttime as the proxy statement discloses he “also manages his family printing, publishing and cable television business.”

Studies have confirmed that under-performing companies lack an independent chairman and companies, worldwide, are routinely separating the positions of Chairman and CEO (CEO Succession 2000-2009: A Decade of Convergence and Compression, Booz & Co., Summer, 2010).

39

Norges Bank Investment Management, has stated in support of a similar proposal:

“The roles of Chairman of the Board and CEO are fundamentally different and should not be held by the same person. There should be a clear division of responsibilities between these powitions to insure a balance of power and authority on the Board.”

If you agree, please vote “FOR” this proposal.

Board of Directors’ Recommendation

The proposal's comparison of Westamerica to Wells Fargo is misplaced given the scale and complexity of the two entities.

At December 31, 2016:	Westamerica		Wells Fargo(3)
Total assets (in thousands)	$	5,366,083	$	1,930,115,000
Number of employees		800		269,000
Number of countries & territories with operations		1		36

The corporate governance structure for any entity should be appropriate for its scale and complexity.

The proposal's comparison of Westamerica’s stock performance to two peers is misleading in regard to stock performance and Westamerica’s leadership.

The five-year stock performance evaluation provided in the shareholder’s proposal begins with December 31, 2010, a point in time when publicly traded bank stock values reflected significant declines due to the “Financial Recession” of 2008 and 2009. Contrary to the banking industry’s negative stock performance as a result of the recession, Westamerica’s stock price rose in 2008, 2009 and 2010, as depicted in the ten-year performance chart on page 15 of the enclosed Form 10-K, Annual Report. During this period, shareholders recognized the value of Westamerica’s leadership and its conservative, value-oriented, and long-term strategies. Westamerica’s exceptional credit quality and strong financial condition leading into the recession positioned the Company to grow by acquiring two failed banks from the FDIC.

Westamerica’s current leadership was established in 1989, coincidentally the same year the proposing shareholder became an investor in Westamerica Bancorporation common stock. The company’s current leadership has followed consistent low-risk value-oriented strategies which have provided superior long-term stock performance through three business cycles:

Total Return with Dividends Reinvested December 29, 1989 through December 31, 2016(4)
Westamerica Bancorporation (WABC)	1,458	%
S&P 500 Index (SPX)	1,018	%
NASDAQ Bank Index (CBNK)	885	%

Westamerica’s shareholders are best served by our current leadership structure.

In light of the current environment for the banking industry and Westamerica’s business strategies, the Board believes that the most effective leadership structure for Westamerica at the present time is for our CEO, David L. Payne, to serve as Chairman of the Board. Combining the positions of Chairman and CEO most effectively utilizes Mr. Payne’s extensive experience and knowledge regarding our Company. Chairman Payne was appointed CEO in

40

1989 and since his appointment identified, negotiated and executed eleven acquisitions to fuel Westamerica’s growth. Each of the acquisitions resulted in higher levels of earnings per share within one or two quarters following the acquisition. Mr. Payne has the knowledge, expertise and experience to continue implementing Westamerica’s long-term strategies.

The Board believes that Mr. Payne has the requisite talent, foresight, and leadership skills to perform at a high-level in the roles of CEO and Chairman. By combining the positions, the Board can respond quickly and effectively to the many business, market and regulatory challenges facing banks in the rapidly changing banking industry.

The Board should retain the flexibility to determine the most effective leadership structure for Westamerica.

The Board's leadership structure should be determined in light of all relevant facts and circumstances at a given time. This approach allows the Board flexibility to determine whether the roles of CEO and Chairman should be separate or combined based upon Westamerica’s needs and the Board's assessment of our Company's leadership from time to time. The Board has deep knowledge of our strategic goals and the various strengths and capabilities of our senior management. Thus, the Board is best positioned to determine the most effective leadership structure for Westamerica at any given time.

Westamerica’s corporate governance practices provide for strong independent leadership and effective independent oversight of our company.

The Board is committed to maintaining high corporate governance standards, and has implemented a structure to provide for Board independence and effective oversight of management. With the exception of Mr. Payne, the Board is composed entirely of independent directors, and key committees are fully comprised of independent directors. Further, in accordance with widely accepted corporate governance guidelines, the Board has established a strong, independent Lead Director who must serve at least one year and has the following clearly delineated and comprehensive duties:

· Presides at all meetings of the board at which the Chairman is not present, including executive sessions of the independent directors;

· Serves as liaison between the chairman and the independent directors;

· Approves information sent to the Board;

· Approves meeting agendas for the Board;

· Approves meeting schedules to assure that there is sufficient time for discussion of all agenda items;

· Has the authority to call meetings of the independent directors; and

· If requested by major shareholders, ensures that he or she is available for consultation and direct communication.

This is the responsibility of management and the independent auditor.

The function of the Audit Committee is oversight. Management is responsible for the preparation and integrity of the Company’s financial statements.

The Committee shall be subject to the provisions of the Company’s bylaws relating to committees of the Board, including those provisions relating to removing committee members and filling vacancies.

The Audit Committee may request any officer or employee of the Company or the Company’s outside counsel or independent auditor to attend a meeting of the Audit Committee.

The Audit Committee shall pre-approve all auditing services and permitted non-audit services and fees to be paid for such services to be performed for the Company by its independent auditor, subject to the limited de minimis exceptions for non-audit services described in Section 10A of the Securities Exchange Act of 1934, provided that compliance with the limitations and procedural requirements of Section 10A is fulfilled.

Any such pre-approval shall be presented to the full Audit Committee at its next scheduled meeting.

The Audit Committee shall make regular reports to the Board.

If pursuant to such investigation the Audit Committee discovers that a material fraud has occurred, the Audit Committee shall (i) assess the Company’s internal controls and implement such remedial measures as it determines necessary or advisable, (ii) cause the Company to take appropriate action against the perpetrator(s) of such fraud and (iii) cause the Company to make appropriate disclosures relating to the matter in the Company’s periodic reports filed with the SEC or otherwise.

37.
