These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Westamerica Bancorporation Tax Deferred Savings/Retirement Plan (ESOP) as of December 31, 2006 and 2005, and the changes in net assets available for benefits for the years ended December 31, 2006, 2005 and 2004, in conformity with accounting principles generally accepted in the United States of America. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets (held at end of year) and reportable transactions, as of and for the year ended December 31, 2006, are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the United States Department of Labor Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audit of the basic 2006 financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic 2006 financial statements taken as a whole. /s/ Perry-Smith LLP ------------------- Sacramento, California June 26, 2007 Page 5 WESTAMERICA BANCORPORATION TAX DEFERRED SAVINGS/RETIREMENT PLAN (ESOP) STATEMENT OF NET ASSETS AVAILABLE FOR PLAN BENEFITS For the Years Ended December 31, 2006 and 2005

The accompanying notes are an integral part of these financial statements. Page 7 WESTAMERICA BANCORPORATION TAX DEFERRED SAVINGS/RETIREMENT PLAN (ESOP) NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF PLAN The following description of the Westamerica Bancorporation (the "Company") Tax Deferred Savings/Retirement Plan (ESOP) (the "Plan") provides only general information. Participants should refer to the Summary Plan Description and Plan Document for a more complete description of the Plan's provisions. General ------- The Plan is a defined contribution plan covering substantially all employees of the Company. The Plan, which became effective October 1, 1985, is intended to be a qualified stock bonus plan under section 401(a) of the Internal Revenue Code ("IRC") and is designated as an employee stock ownership plan or ESOP. Portions of the Plan are also intended to qualify as a qualified cash or deferred arrangement within the meaning of section 401(k) of the IRC. Effective April 1, 2006, the Plan was amended and restated to provide for Roth elective contributions. The Employee Benefits and Compensation Committee of the Company's Board of Directors (the "Committee") delegates the administration of the Plan to the Company's Pension Management Committee. The Committee has the responsibility for the general operation of the Plan, including the resolution of any questions arising under the Plan agreement. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Investments in the Plan are participant directed, with the exception of employer contributions which are invested in shares of the Company's common stock at the time of contribution. Subsequent to investment in the Company's common stock, participants may direct employer matching contributions among all investment options. Vanguard Fiduciary Trust Company serves as Trustee of the Plan. During 2005, Redwood Empire Bancorp (Redwood) was merged into Westamerica Bancorporation. The Plan was amended in order for former employees of Redwood's wholly-owned subsidiary, National Bank of the Redwoods, to be credited with their prior service for eligibility in the Plan. Eligibility ----------- Under the Plan, employees of the Company who are compensated on a salaried basis become eligible to participate in the plan on the first day of the calendar month coinciding with or following the date the employee completes 90 consecutive days of service with the Company or completes 1,000 service hours in a 12-month consecutive period. Vesting ------- Participants are immediately vested in their salary-deferral contributions, the Company's discretionary and matching contributions, plus actual earnings thereon. Page 8 1. DESCRIPTION OF PLAN (Continued) Contributions ------------- Each year, participants may make salary deferral contributions in any whole percentage of pretax annual compensation subject to certain IRC limitations. Effective April 1, 2006, participants may also elect to make salary deferral contributions on an after-tax basis in whole percentage increments, subject to certain limitations defined by the Plan. These contributions are designated as Roth elective contributions. The Company makes a matching contribution equal to 100 percent of the participant's elective contribution and Roth elective contribution, up to a maximum of 6 percent of the participant's compensation. Additional amounts may be contributed at the discretion of the Company's Board of Directors. Participants may also contribute amounts representing distributions from other qualified Roth accounts, defined benefit, or contribution plans. For the years ended December 31, 2006, 2005 and 2004, the Company made no discretionary contributions. Company contributions are subject to certain IRC limitations. Participant Accounts -------------------- Individual accounts are maintained for each Plan participant. Each participant's account is credited with the participant's contribution, allocation of the Company's matching and discretionary contributions, allocation of Plan earnings, and charged with withdrawals, allocations of Plan losses and administrative expenses. Employer matching contributions are allocated to participants based on the Participant's elective contribution. Employer discretionary contributions are allocated to the account of each participant in ratio of the participant's eligible compensation to the total eligible compensation for all Plan participants. Participants' Investment Options -------------------------------- Company matching contributions are invested in the Westamerica Common Stock Fund in accordance with the Plan Document. Participants may redirect Company matching contributions from the Westamerica Common Stock Fund to other investment options at their discretion. Participants direct participant contributions in whole or in part in any of the following investment fund options as of December 31, 2006: * The Westamerica Common Stock Fund, which is invested in the Company's common stock and temporary interest-bearing money market funds. * Vanguard 500 Index Fund, which invests in the 500 stocks that make up the unmanaged Standard & Poor's 500 Composite Stock Price Index, a widely recognized benchmark of U.S. stock market performance. Page 9 1. DESCRIPTION OF PLAN (Continued) Participants' Investment Options (Continued) -------------------------------- * Vanguard Explorer Fund, which invests in a diversified group of small- company stocks with prospects for above-average growth. The fund may invest up to 20% in foreign securities and up to 15% in restricted or illiquid securities. * Vanguard Morgan Growth Fund, which invests primarily in stocks of large and mid-sized companies that have strong records of growth in sales and earnings or that have performed well during certain market cycles. * Vanguard Prime Money Market Fund, which invests in short-term, high- quality money market instruments issued by financial institutions, nonfinancial corporations, the U.S. government, and federal agencies. * Vanguard Total Bond Market Index Fund, which invests in bonds that attempt to match the performance of the unmanaged Lehman Brothers Aggregate Bond Index, which is a widely recognized measure of the taxable U.S. bond market. * Vanguard Total International Stock Index Fund, which invests in three Vanguard international index funds: a European fund, a Pacific fund, and an emerging markets fund. These funds invest in the stock of companies in more than 30 countries. * Vanguard Windsor II Fund, which invests in a diversified group of out-of- favor stocks of large capitalization companies. The stocks selected generally sell at prices below the market average compared to their dividend income and future return potential. * Vanguard Extended Market Index Fund, which invests in a broadly diversified portfolio of stocks of small and medium sized companies that are regularly traded on the New York and American Stock Exchanges and NASDAQ over- the-counter market. The portfolio is designed to be representative of the Wilshire 4500 Index. * Vanguard Short-Term Federal Fund, which invests primarily in short-term securities issued by U.S. government agencies, but may also invest in U.S. Treasury securities and in repurchase agreements backed by U.S. Treasury or federal agency securities. To reduce fluctuations in its share price, the fund maintains an average maturity of 1 to 3 years. * Vanguard Target Retirement Income Fund, which invests in other Vanguard mutual funds according to an asset allocation designed for investors currently in retirement. It typically allocates 70% of assets to bonds and 30% to stocks. * Vanguard Target Retirement 2005, which is invested in other Vanguard mutual funds. It typically allocates 50% of assets to bonds and 50% to stocks. Page 10 1. DESCRIPTION OF PLAN (Continued) Participants' Investment Options (Continued) -------------------------------- * Vanguard Target Retirement 2010, which is invested in other Vanguard mutual funds. It typically allocates 57% of assets to stock, 41% to bonds and 2% to stable value funds. * Vanguard Target Retirement 2015, which is invested in other Vanguard mutual funds according to an asset allocation designed for investors currently in retirement.

It typically allocates 90% of assets to stocks and 10% to bonds. * Vanguard Target Retirement 2050, which is invested in other Vanguard mutual funds. It typically allocates 90% of its assets to stocks and 10% to bonds. Participants may change their investment options at any time directly through The Vanguard Group. Participant Loans ----------------- Participants may borrow a minimum of $1,000 up to a maximum equal to the lesser of 50 percent of their account balance, 100 percent of participant contributions, or $50,000. For the purposes of this limit, all qualified plans of the Company shall be considered one plan. Loans are secured by the balance in the participant's account. Participant loans are funded by selling investments in the borrowing participant's accounts and bear interest at prevailing market rates at the time the funds are borrowed. Loan terms range from 1 to 5 years. Principal and interest is paid ratably through payroll deductions and invested in the borrowing participant's accounts in accordance with their investment directions. Page 11 1. DESCRIPTION OF PLAN (Continued) Payment of Benefits ------------------- Upon termination of service for any reason, a participant may elect to receive a lump-sum distribution equal to the value in his or her account. Distributions for the value of a participant's account invested in the Westamerica Common Stock Fund stock are made in the form of the Company's common stock plus cash for any fractional shares or, if a participant elects, in cash or an in-kind transfer, as provided by the Plan document. Participants may also receive in- service distributions on account of hardship or after attaining age 59 1/2. Cash dividends paid on Westamerica Bancorporation common stock allocated to participant accounts may be paid to participants in cash or be credited to the participant's account as earnings. If the value of a separated participant's benefit is not more than $1,000, the benefit shall be automatically paid in a single lump sum in cash or, if elected, directly to an eligible retirement plan. Benefits payable to participants for amounts greater than $1,000 may be made in cash or other form of distribution, as defined by the Plan. As of December 31, 2006 and 2005, there were no benefits payable to participants that have elected to withdraw from the Plan but have not yet been paid. Voting Rights ------------- Each participant is entitled to exercise voting rights attributable to the Westamerica Bancorporation common stock shares allocated to his or her account and is notified by the Trustee prior to the time that such rights are to be exercised. The Trustee is not permitted to vote any allocated share for which instructions have not been given by a participant. Plan Termination ---------------- Although it has not expressed any interest to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan, subject to the provisions of ERISA. Administrative Expenses ----------------------- The Company provides bookkeeping and other administrative services for the Plan at no charge. The Company pays the Plan's annual account maintenance fees for participants actively employed by the Company and other administrative expenses. 2. SUMMARY OF ACCOUNTING POLICIES Basis of Accounting ------------------- The financial statements of the Plan have been prepared in accordance with accounting principles generally accepted in the United States of America. Page 12 2. SUMMARY OF ACCOUNTING POLICIES (Continued) Use of Estimates ---------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan's management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. The Plan utilizes various investment instruments, including the common stock of the Company and mutual funds. Investment securities, in general, are exposed to various risks, such as interest rate, credit, currency and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements. Concentrations of Investments ----------------------------- Included in investments at December 31, 2006 and 2005 are shares of the Westamerica Common Stock Fund amounting to $29,608,768 and $34,398,813, respectively. The Westamerica Common Stock Fund represents 54% and 61% of total investments at December 31, 2006 and 2005, respectively. A significant decline in the market value of the Company's stock would have a materially adverse effect on the Plan's net assets available for benefits. Investment Valuation and Income Recognition ------------------------------------------- The Plan's investments are stated at fair value. Shares of registered investment companies (mutual funds) are reported at fair value based on the quoted market price of the fund, which represents the net asset value of shares held by the Plan at year end. The Company's common stock is valued at its quoted market price. Participant loans are valued at their outstanding loan balances. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex- dividend date. Net appreciation (depreciation) in fair value of investments includes net unrealized market appreciation (depreciation) of investments and net realized gains and losses on the sale of investments during the period. Management fees and operating expenses charged to the Plan for investments in shares of registered investment companies (mutual funds) are deducted from income earned on a daily basis and are not separately reflected. Consequently, management fees and operating expenses are reflected as a reduction of investment return for such investments. Trustee fees for Westamerica Bancorporation common stock are charged to the Westamerica Common Stock Fund. Payment of Benefits ------------------- Benefits are recorded when paid. Page 13 2. SUMMARY OF ACCOUNTING POLICIES (Continued) Reclassifications ----------------- Certain amounts shown in the prior year have been reclassified to conform to the current year presentation. Impact of New Financial Accounting Standards -------------------------------------------- Fair Value Measurements In September 2006, the Financial Accounting Standards Board (FASB) issued Statement No. 157 (SFAS 157), Fair Value Measurements. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value but does not expand the use of fair value in any new circumstances. In this standard, the FASB clarifies the principle that fair value should be based on the assumptions market participants would use when pricing the asset or liability. In support of this principle, SFAS 157 establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The provisions of SFAS 157 are effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The provisions should be applied prospectively, except for certain specifically identified financial instruments. Management does not expect the adoption of SFAS 157 to have a material impact to the Plan's financial position or results of operations. Fair Value Accounting In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities - Including an Amendment of FASB Statement No. 115 (SFAS 159). This Statement permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This Statement is expected to expand the use of fair value measurement, which is consistent with the FASB's long-term measurement objectives for accounting for financial instruments. SFAS 159 is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of SFAS 157. Management has not chosen early adoption of SFAS 159. Management is in the process of evaluating the impact the adoption of SFAS 159 will have on the Plan's financial position and results of operations. Page 14 3. INVESTMENTS The Plan's investments, including investments bought, sold, and held during the year, appreciated in value by $262,793 and $7,418,432 during 2006 and 2004, respectively, and depreciated in value by $2,948,412 during 2005, as follows:

Page 15 5. FEDERAL INCOME TAX STATUS The Internal Revenue Service has determined and informed the Company by a letter dated December 12, 2001, that the Plan is qualified and the trust established under the Plan is tax-exempt, under the appropriate sections of the Internal Revenue Code. The Plan has been amended since receiving the determination letter; however, the Plan's management and the Plan's tax counsel believe that the Plan currently is designed and being operated in compliance with the applicable requirements of the Internal Revenue Code and the Plan continues to be tax exempt. Therefore, no provision for income taxes has been included in the Plan's financial statements. 6. RELATED PARTY TRANSACTIONS Plan investments include shares of mutual funds, including the Westamerica Common Stock Fund which invests in the common stock of the Company, managed by an affiliate of Vanguard Fiduciary Trust Company (VFTC). VFTC is the Trustee as defined by the Plan and, therefore, these transactions qualify as party-in- interest transactions. Fees paid by the Plan for investment management services were included as a reduction of the return earned on each fund. Fees paid by the Plan for trustee services in connection with the Westamerica Common Stock Fund for the years ended December 31, 2006, 2005 and 2004 amounted to $45,837, $49,324 and $51,327, respectively. 7.

In addition, the Plan was amended to provide for Company matching contributions on both participant elective and Roth contributions. Effective January 2006, the hardship withdrawal rules were also revised.
