NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of Management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three months ended March 31, 2011 and 2010 are not necessarily indicative of the results expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010

The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing that would require recognition or disclosure in its consolidated financial statements.

Note 2: Accounting Policies

The Company’s accounting policies are discussed in Note 1 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. Certain amounts in prior periods have been reclassified to conform to the current presentation.

Nonmarketable Equity Securities. Nonmarketable equity securities include securities that are not publicly traded and securities acquired for various purposes, such as to meet regulatory requirements (for example, Federal Home Loan Bank stock). These securities are accounted for under the cost method and are included in other assets. The Company reviews those assets accounted for under the cost method at least quarterly for possible declines in value that are considered “other than temporary”. The Company’s review typically includes an analysis of the facts and circumstances of each investment, the expectations for the investment’s cash flows and capital needs, the viability of its business model and exit strategy. The asset value is reduced when a decline in value is considered to be other than temporary. The Company recognizes the estimated loss as a loss from equity investments in noninterest income.

Certain accounting policies underlying the preparation of these financial statements require Management to make estimates and judgments. These estimates and judgments may significantly affect reported amounts of assets and liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. Management exercises judgment to estimate the appropriate level of the allowance for credit losses and the acquisition date fair value of purchased loans, which are discussed in the Company’s accounting policies.

As described in Note 3 below, Westamerica Bank (“Bank”) acquired assets and assumed liabilities of the former Sonoma Valley Bank on August 20, 2010. The acquired assets and assumed liabilities were measured at estimated fair values, as required by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 805, Business Combinations. Management made significant estimates and exercised significant judgment in accounting for the acquisition. Management judgmentally measured loan fair values based on loan file reviews (including borrower financial statements and tax returns), appraised collateral values, expected cash flows, and historical loss factors. Repossessed loan collateral was primarily valued based upon appraised collateral values. The Bank also recorded an identifiable intangible asset representing the value of the core deposit customer base of Sonoma Valley Bank based on Management’s evaluation of the cost of such deposits relative to alternative funding sources. In determining the value of the identifiable intangible asset, Management used significant estimates including average lives of depository accounts, future interest rate levels, the cost of servicing various depository products, and other significant estimates. Management used quoted market prices to determine the fair value of investment securities and FHLB advances.

The acquired assets of Sonoma Valley Bank include loans; such loans are not indemnified by the Federal Deposit Insurance Corporation (FDIC). However, on February 6, 2009, the Bank acquired loans in a business combination that are indemnified by the FDIC, as described in Note 2 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. Pursuant to acquisition accounting, the loans in each business combination were measured at their estimated fair value at the respective acquisition date. This method of measuring the carrying value of purchased loans differs from loans originated by the Company, and as such, the Company identifies purchased loans not indemnified by the FDIC as “Purchased Non-covered Loans” and purchased loans indemnified by the FDIC as “Purchased Covered Loans.”

- 8 -

Loans originated by the Company are measured at the principal amount outstanding, net of unearned discount and unamortized deferred fees and costs. These loans are identified as “Originated Loans.”

Recently Issued Accounting Standards

Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2011-01,Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20 (Topic 310), was issued January 2011 deferring the new disclosure requirements (paragraphs 310-10-50-31 through 50-34 of theFASB Accounting Standards Codification) about troubled debt restructurings to be concurrent with the effective date of the guidance for determining what constitutes a troubled debt restructuring, as presented in proposed Accounting Standards Update,Receivables (Topic 310): Clarifications to Accounting for Troubled Debt Restructurings by Creditors. As a result of the issuance of Update 2011-02, the provisions of Update 2011-01 are effective for the first interim or annual period beginning on or after June 15, 2011 or September 30, 2011 for the Company, and should be applied retrospectively to the beginning of the annual period of adoption. Management does not expect the adoption of the Update to have a material effect on the Company’s financial statements at the date of adoption.

FASB ASU 2011-02,A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring, was issued April 2011 providing additional guidance for creditors in determining whether a creditor has granted a concession and whether a debtor is experiencing financial difficulties for purposes of determining whether a restructuring constitutes a troubled debt restructuring. The provisions of this standard are effective for the first interim or annual period beginning on or after June 15, 2011 or September 2011 for the Company, and should be applied retrospectively to the beginning of the annual period of adoption. Management does not expect the adoption of the Update to have a material effect on the Company’s financial statements at the date of adoption.

Note 3: Acquisition

On August 20, 2010, the Bank purchased substantially all the assets and assumed substantially all the liabilities of Sonoma from the FDIC, as Receiver of Sonoma. Sonoma operated 3 commercial banking branches within Sonoma County, California. The FDIC took Sonoma under receivership upon Sonoma’s closure by the California Department of Financial Institutions at the close of business August 20, 2010. Westamerica Bank purchased substantially all of Sonoma’s net assets at a discount of $43 million and paid a $5 million deposit premium.

The Sonoma acquisition was accounted for under the purchase method of accounting in accordance with FASB ASC 805, Business Combinations. The statement of net assets acquired as of August 20, 2010 and the resulting bargain purchase gain are presented in the following table. The purchased assets and assumed liabilities were recorded at their respective acquisition date fair values, and identifiable intangible assets were recorded at fair value. Fair values are preliminary and subject to refinement for up to one year after the closing date of a merger as information relative to closing date fair values becomes available. A “bargain purchase” gain totaling $178 thousand resulted from the acquisition and is included as a component of noninterest income on the statement of income. The amount of the gain is equal to the amount by which the fair value of assets purchased exceeded the fair value of liabilities assumed. Sonoma’s results of operations prior to the acquisition are not included in Westamerica’s statement of income.

Expected maturities of mortgage-backed securities can differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may affect the yield on the carrying value of mortgage-backed securities.

The unrealized losses on the Company’s investments in collateralized mortgage obligations and asset backed securities were caused by market conditions for these types of investments. The Company evaluates these securities on a quarterly basis including changes in security ratings issued by rating agencies, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure, and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be AAA rated by one or more major rating agencies.

The unrealized losses on the Company’s investments in obligations of states and political subdivisions were caused by conditions in the municipal securities market. The Company’s investments in obligations of states and political subdivisions primarily finance essential community services such as school districts, water delivery systems, hospitals and fire protection services. Further, these bonds are primarily “bank qualified” issues whereby the issuing authority’s total debt issued in any one year does not exceed $30 million, thereby qualifying the bonds for tax-exempt status for federal income tax purposes. Therefore, “bank qualified” bonds are relatively small in amount providing a high degree of diversification within the Company’s investment portfolio. The Company evaluates these securities quarterly to determine if a change in security rating has occurred or the municipality has experienced financial difficulties. Substantially all of these securities continue to be investment grade rated.

The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2011.

The fair values of the investment securities could decline in the future if the general economy deteriorates, credit ratings decline, or the liquidity for securities is low. As a result, other than temporary impairments may occur in the future.

The Bank’s customers are small businesses, professionals and consumers. Given the scale of these borrowers, corporate credit rating agencies do not evaluate the borrowers’ financial condition. The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for loss recognition, as “substandard,” “doubtful,” and “loss.” If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review examinations, assigned risk grades will be re-evaluated promptly. Credit risk grades assigned by the Loan Review Department are subject to review by the Bank’s regulatory authority during regulatory examinations.

The following summarizes the credit risk profile by internally assigned grade:

The Company had no troubled debt restructurings at March 31, 2011 and December 31, 2010.

The Company pledges loans to secure borrowings from the Federal Home Loan Bank (FHLB). At March 31, 2011, loans pledged to secure borrowing totaled $106.7 million compared with $138.0 million at December 31, 2010. The FHLB does not have the right to sell or repledge such loans.

There were no loans held for sale at March 31, 2011 and December 31, 2010.

Note 6: Concentration of Credit Risk

The Company’s business activity is with customers in Northern and Central California. The loan portfolio is well diversified within the Company’s geographic market, although the Company has significant credit arrangements that are secured by real estate collateral. In addition to real estate loans outstanding as disclosed in Note 5, the Company had loan commitments and standby letters of credit related to real estate loans of $12.4 million and $13.0 million at March 31, 2011 and December 31, 2010, respectively. The Company requires collateral on all real estate loans with loan-to-value ratios generally no greater than 75% on commercial real estate loans and no greater than 80% on residential real estate loans at origination.

Note 7: Goodwill and Identifiable Intangible Assets

The Company has recorded goodwill and other identifiable intangibles associated with purchase business combinations. Goodwill is not amortized, but is periodically evaluated for impairment. The Company did not recognize impairment during the quarter ended March 31, 2011.

The carrying values of goodwill were (in thousands):

December 31, 2010	$	121,673
March 31, 2011	$	121,673

Identifiable intangibles are amortized to their estimated residual values over their expected useful lives. Such lives and residual values are also periodically reassessed to determine if any amortization period adjustments are indicated. During the quarter ended March 31, 2011, no such adjustments were recorded.

Note 8: Commitments and Contingent Liabilities

Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan commitments were $397.8 million and $422.7 million at March 31, 2011 and December 31, 2010, respectively. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. Standby letters of credit are primarily issued to support customers’ short-term financing requirements and must meet the Company’s normal credit policies and collateral requirements. Standby letters of credit outstanding totaled $24.9 million and $25.5 million at March 31, 2011 and December 31, 2010, respectively. The Company also had commitments for commercial and similar letters of credit of $4.1 million and $3.4 million at March 31, 2011 and December 31, 2010, respectively.

Due to the nature of its business, the Company is subject to various threatened or filed legal cases resulting from loan collection efforts, transaction processing for deposit accounts including the order of posting transactions and the assessment of overdraft fees, and employment practices. The Company establishes a liability for contingent litigation losses for any legal matter when payments associated with the claims become probable and the costs can be reasonably estimated. Legal costs related to covered assets are eighty percent indemnified under loss-sharing agreements with the FDIC if certain conditions are met.

Note 9: Fair Value Measurements

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale investment securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as certain loans held for investment and other assets. These nonrecurring fair value adjustments typically involve the lower-of-cost-or-fair value accounting or impairment or write-down of individual assets.

- 22 -

In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for an asset or liability in an orderly transaction between market participants on the measurement date. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance.

The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 — Valuation is based upon quoted prices for identical instruments traded in active exchange markets, such as the New York Stock Exchange. Level 1 includes U.S. Treasury and federal agency securities, which are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 includes mortgage-backed securities, municipal bonds and residential collateralized mortgage obligations as well as other real estate owned and impaired loans collateralized by real property where the fair value is generally based upon independent market prices or appraised values of the collateral.

Level 3 — Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Level 3 includes those impaired loans collateralized by business assets where the expected cash flow has been used in determining the fair value.

Assets Recorded at Fair Value on a Nonrecurring Basis

The Company may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis that were still held in the balance sheet at March 31, 2011 and December 31, 2010, the following table provides the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets at period end.

Disclosures about Fair Value of Financial Instruments

The following section describes the valuation methodologies used by the Company for estimating fair value of financial instruments not recorded at fair value.

Cash and Due from BanksThe carrying amount of cash and amounts due from banks approximate fair value due to the relatively short period of time between their origination and their expected realization.

Money Market AssetsThe carrying amount of money market assets approximate fair value due to the relatively short period of time between their origination and their expected realization.

Investment Securities Held to MaturityThe fair values of investment securities were estimated using quoted prices as described above for Level 1 and Level 2 valuation.

LoansLoans were separated into two groups for valuation. Variable rate loans, except for those described below, which reprice frequently with changes in market rates were valued using historical cost. Fixed rate loans and variable rate loans that have reached their minimum contractual interest rates were valued by discounting the future cash flows expected to be received from the loans using current interest rates charged on loans with similar characteristics. Additionally, the allowance for loan losses of $34.3 million at March 31, 2011 and $35.6 million at December 31, 2010 and the fair value discount due to credit default risk associated with purchased covered and purchased non-covered loans of $57.2 million and $28.9 million, respectively at March 31, 2011 and $61.8 million and $32.4 million, respectively at December 31, 2010 were applied against the estimated fair values to recognize estimated future defaults of contractual cash flows. The Company does not consider these values to be a liquidation price for the loans.

FDIC ReceivableThe fair value of the FDIC receivable recorded in Other Assets was estimated by discounting estimated future cash flows using current market rates for financial instruments with similar characteristics.

Deposit LiabilitiesThe carrying amount of checking accounts, savings accounts and money market accounts approximates fair value due to the relatively short period of time between their origination and their expected realization. The fair values of time deposits were estimated by discounting estimated future cash flows related to these financial instruments using current market rates for financial instruments with similar characteristics.

Short-Term Borrowed FundsThe carrying amount of securities sold under agreement to repurchase and other short-term borrowed funds approximate fair value due to the relatively short period of time between their origination and their expected realization. The fair values of term repurchase agreements were estimated by using interpolated yields for financial instruments with similar characteristics.

Federal Home Loan Bank AdvancesThe fair values of FHLB advances were estimated by using interpolated yields for financial instruments with similar characteristics.

Debt Financing and Notes PayableThe fair values of debt financing and notes payable were estimated by using interpolated yields for financial instruments with similar characteristics.

Restricted Performance Share GrantsThe fair value of liabilities for unvested restricted performance share grants recorded in Other Liabilities were estimated using quoted prices as described above for Level 1 valuation.

The table below is a summary of fair value estimates for financial instruments, excluding financial instruments recorded at fair value on a recurring basis. The values assigned do not necessarily represent amounts which ultimately may be realized. In addition, these values do not give effect to discounts to fair value which may occur when financial instruments are sold in larger quantities. The carrying amounts in the following table are recorded in the balance sheet under the indicated captions.

The Company has not included assets and liabilities that are not financial instruments, such as goodwill, long-term relationships with deposit, merchant processing and trust customers, other purchased intangibles, premises and equipment, deferred taxes and other assets and liabilities. The total estimated fair values do not represent, and should not be construed to represent, the underlying value of the Company.

The majority of the Company’s standby letters of credit and other commitments to extend credit carry current market interest rates if converted to loans. No premium or discount was ascribed to these commitments because virtually all funding would be at current market rates.

Note 11: Earnings Per Common Share

The table below shows earnings per common share and diluted earnings per common share. Basic earnings per common share are computed by dividing net income applicable to common equity by the average number of common shares outstanding during the period. Diluted earnings per common share are computed by dividing net income applicable to common equity by the average number of common shares outstanding during the period plus the impact of common stock equivalents.

For the three months ended March 31, 2011, options to purchase 1.0 million shares of common stock were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect. For the three months ended March 31, 2010, options to purchase 294 thousand shares of common stock were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Westamerica Bancorporation and subsidiaries (the “Company”) reported first quarter 2011 net income of $22.4 million or $0.77 diluted earnings per common share. These results compare to net income applicable to common equity of $23.6 million or $0.80 diluted earnings per common share and $23.7 million or $0.81 diluted earnings per common share, respectively, for the first and fourth quarters of 2010.

Acquisition

Westamerica Bank (“Bank”) acquired assets and assumed liabilities of the former Sonoma Valley Bank (“Sonoma”) on August 20, 2010. The acquired assets and assumed liabilities were measured at estimated fair values, as required by FASB ASC 805, Business Combinations. Management made significant estimates and exercised significant judgment in accounting for the acquisition. Management judgmentally measured loan fair values based on loan file reviews (including borrower financial statements and tax returns), appraised collateral values, expected cash flows, and historical loss factors. Repossessed loan collateral was primarily valued based upon appraised collateral values. The Bank also recorded an identifiable intangible asset representing the value of the assumed core deposit customer base of Sonoma based on Management’s evaluation of the cost of such deposits relative to alternative funding sources. In determining the value of the identifiable intangible asset, Management used significant estimates including average lives of depository accounts, future interest rate levels, the cost of servicing various depository products, and other significant estimates. Management used quoted market prices to determine the fair value of investment securities, Federal Home Loan Bank (“FHLB”) advances and other borrowings which were purchased and assumed. The acquired Sonoma operations were fully integrated into the Company’s traditional operating systems and practices in February 2011. First quarter 2011 results include expenses related to the integration of the former Sonoma of $393 thousand after tax, equivalent to $0.01 diluted earnings per share.

Net Income

Following is a summary of the components of net income for the periods indicated:

	Three months ended
	March 31,						December 31,
	2011			2010			2010
	(In thousands, except per share data)
Net interest income (FTE)	$	54,993		$	57,029		$	56,412

Income before taxes (FTE)		35,613			37,668			37,242
Income tax provision (FTE)		(13,231	)		(14,092	)		(13,511	)
Net income	$	22,382		$	23,576		$	23,731
Average diluted common shares		29,225			29,596			29,341
Diluted earnings per common share	$	0.77		$	0.80		$	0.81

Net income to average total assets (annualized)		1.84	%		1.99	%		1.87	%

Net income for the first quarter of 2011 was $1.2 million or 5.1% less than the same quarter of 2010, the net result of declines in net interest income (FTE) and noninterest income, partially offset by decreases in noninterest expense and income tax provision (FTE). A $2.0 million or 3.6% decrease in net interest income (FTE) was mostly attributed to lower average balances of loans and lower yields on earning assets, partially offset by higher average balances of investments, lower average balances of short-term borrowings and lower rates paid on interest-bearing liabilities. The provision for loan losses remained the same, reflecting Management’s evaluation of losses inherent in the loan portfolio not covered by loss-sharing agreements with the Federal Deposit Insurance Corporation (“FDIC”) and purchased loan credit-default discounts. Noninterest income decreased $727 thousand mainly due to lower service charges on deposit accounts. Noninterest expense decreased $708 thousand mostly due to lower personnel expenses.

Comparing the first quarter of 2011 to the fourth quarter of 2010, net income decreased $1.3 million, primarily due to lower net interest income (FTE) and lower noninterest income, partially offset by decreases in noninterest expense and income tax provision (FTE). The lower net interest income (FTE) was primarily caused by a lower average volume of loans and lower yields on interest earning assets, partially offset by higher average balances of investments, lower average balances of interest-bearing liabilities and lower rates paid on those liabilities. The provision for loan losses remained the same, reflecting Management’s evaluation of losses inherent in the loan portfolio not covered by loss-sharing agreements with the FDIC and purchased loan credit-default discounts. Noninterest income decreased $400 thousand largely due to lower service charges on deposit accounts. Noninterest expense declined $190 thousand.

Net Interest Income

Following is a summary of the components of net interest income for the periods indicated:

	Three months ended
	March 31,						December 31,
	2011			2010			2010
	(In thousands)
Interest and fee income	$	52,494		$	56,003		$	54,871
Interest expense		(2,303	)		(3,534	)		(3,065	)
FTE adjustment		4,802			4,560			4,606
Net interest income (FTE)	$	54,993		$	57,029		$	56,412
Average earning assets	$	4,153,110		$	4,111,345		$	4,164,013
Net interest margin (FTE) (annualized)		5.35	%		5.60	%		5.39	%

Net interest income (FTE) decreased during the first quarter of 2011 by $2.0 million or 3.6% from the same period in 2010 to $55.0 million, mainly due to lower average balances of loans (down $126 million) and lower yields on earning assets (down 0.38%), partially offset by higher average balances of investments (up $168 million), lower average balances of short-term borrowings (down $109 million) and lower rates paid on interest-bearing liabilities (down 0.16%).

Comparing the first quarter of 2011 with the fourth quarter of 2010, net interest income (FTE) decreased $1.4 million or 2.5%, primarily due to a lower average volume of loans (down $88 million) and lower yields on interest earning assets (down 0.11%), partially offset by higher average balances of investments (up $77 million), lower average balances of interest-bearing liabilities (down $94 million) and lower rates paid on interest-bearing liabilities (down 0.07%).

Economic conditions and deleveraging by businesses and individuals have reduced loan volumes, placing greater reliance on lower-yielding investment securities.

At March 31, 2011, purchased FDIC covered loans represented 23 percent of the Company’s loan portfolio. Under the terms of the FDIC loss-sharing agreements, the FDIC is obligated to reimburse the Bank 80 percent of loan interest income foregone on covered loans. Such reimbursements are limited to the lesser of 90 days contractual interest or actual unpaid contractual interest at the time a principal loss is recognized in respect to the underlying loan.

Interest and Fee Income

Interest and fee income (FTE) for the first quarter of 2011 decreased $3.3 million or 5.4% from the same period in 2010. The decrease was caused by lower average balances of loans (down $126 million) and lower yields on earning assets (down 0.38%), partially offset by higher average balances of investments (up $168 million). The total average balances of loans declined due to decreases in the average balances of taxable commercial loans (down $71 million), residential real estate loans (down $49 million), indirect auto loans (down $26 million) and tax-exempt commercial loans (down $19 million), partially offset by a $13 million increase in the average balance of commercial real estate loans. The average investment portfolio increased largely due to higher average balances of U.S. Government sponsored entities (up $144 million), corporate securities (up $75 million) and municipal securities (up $70 million), partially offset by collateralized mortgage obligations (down $66 million) and residential mortgage backed securities (down $56 million). The average yield on the Company’s earning assets decreased from 5.95% in the first quarter of 2010 to 5.57% in the corresponding period of 2011. The composite yield on loans declined 0.2% to 5.97%. Nonperforming loans are included in average loan volumes used to compute loan yields; fluctuations in nonaccrual loan volumes impact loan yields. The investment portfolio yield decreased 0.66% to 4.70%. The decline in loan and investment yields is primarily due to relatively low market rates and competitive loan pricing.

- 30 -

Comparing the first quarter of 2011 with the fourth quarter of 2010, interest and fee income (FTE) was down $2.2 million or 3.7%. The decrease resulted from a lower average volume of loans and lower yields on interest earning assets (down 0.11%), partially offset by higher average balances of investments. Average interest earning assets decreased $11 million or 0.3% in the first quarter of 2011 compared with the fourth quarter of 2010 due to an $88 million decrease in average loans and a $77 million increase in average investments. The decrease in the average balance of the loan portfolio was attributable to decreases in average balances of commercial real estate loans (down $32 million), taxable commercial loans (down $23 million), residential real estate loans (down $12 million), tax-exempt commercial loans (down $5 million), direct consumer loans (down $7 million) and indirect auto loans (down $5 million). The average investment portfolio increased mostly due to higher average balances of municipal securities (up $45 million) and U.S. government sponsored entity obligations (up $40 million). The average yield on earning assets for the first quarter of 2011 was 5.57% compared with 5.68% in the fourth quarter of 2010. The loan portfolio yield for the first quarter of 2011 compared with the fourth quarter of 2010 was lower by 0.06%.

Interest expense in the first quarter of 2011 decreased $1.2 million or 34.8% compared with the same period in 2010. The decrease was attributable to lower average balances of short-term borrowings (down $109 million) and time deposits (down $64 million), and lower rates paid on interest-bearing liabilities (down 0.16%). Average interest-bearing liabilities increased $25 million or 0.9% due to increases in average balances of interest-bearing deposits (up $100 million) and assumed Sonoma FHLB advances (up $33 million). Partially offsetting the increase was a $109 million decline in the average balance of short-term borrowed funds due to repayment of term repurchase agreements of $100 million in December of 2010. Higher average balances of interest-bearing deposits were attributable to increases in average balances of money market savings (up $60 million), money market checking accounts (up $53 million), preferred money market savings (up $29 million), regular savings (up $23 million), partially offset by a $56 million decrease in average balances of time deposits less than $100 thousand. The average rate paid on interest-bearing liabilities decreased from 0.5% in the first quarter of 2010 to 0.34% in the same quarter of 2011. Rates on interest-bearing deposits decreased 0.1% to 0.29% primarily due to decreases in rates paid on time deposits less than $100 thousand (down 0.14%), time deposits $100 thousand or more (down 0.07%) and preferred money market savings (down 0.31%). Rates on short-term borrowed funds decreased 0.76%. Rates on debt financing payable declined 3.37% due to the adjustment of the premium amortization on a $10 million subordinated note, which the Company intends to redeem in August 2011. The redemption premium will approximate 5 percent of the $10 million principal amount.

Comparing the first quarter of 2011 with the fourth quarter of 2010, interest expense declined $762 thousand or 24.9%, due to lower average balances of interest-bearing liabilities (down $94 million) and lower rates paid on interest-bearing liabilities (down 0.07%). Average interest-bearing liabilities during the first quarter of 2011 fell primarily due to declines in the average balances of short-term borrowed funds (down $71 million) and time deposits less than $100 thousand (down $16 million), money market savings (down $16 million), partially offset by a $25 million increase in the average balance of preferred money market savings. Lower average balances of short-term borrowed funds were attributable to repayment of term repurchase agreements of $100 million in December of 2010. Rates paid on interest-bearing liabilities averaged 0.34% during the first quarter of 2011 compared with 0.41% for the fourth quarter of 2010. The average rate paid on interest-bearing deposits declined 0.01% to 0.29% in the first quarter of 2011 compared with the fourth quarter of 2010 mainly due to lower rates on money market savings (down 0.05%) and preferred money market savings (down 0.12%). Lower rates on short-term borrowed funds (down 0.76%) and debt financing and notes payable (down 3.35%) contributed to the reduction in rates paid on interest-bearing liabilities. Rates on debt financing payable declined 3.35% due to the adjusted premium amortization described in the preceding paragraph.

Net Interest Margin (FTE)

The following summarizes the components of the Company’s net interest margin for the periods indicated:

	Three months ended
	March 31,						December 31,
	2011			2010			2010
Yield on earning assets (FTE)		5.57	%		5.95	%		5.68	%
Rate paid on interest-bearing liabilities		0.34	%		0.50	%		0.41	%
Net interest spread (FTE)		5.23	%		5.45	%		5.27	%
Impact of noninterest-bearing funds		0.12	%		0.15	%		0.12	%
Net interest margin (FTE)		5.35	%		5.60	%		5.39	%

- 31 -

During the first quarter of 2011, the net interest margin (FTE) decreased 0.25% compared with the same period in 2010. Lower yields on earning assets were partially offset by lower rates paid on interest-bearing liabilities and resulted in a 0.22% decrease in net interest spread (FTE). The net interest margin contribution of noninterest-bearing demand deposits reduced the net interest margin (FTE) to 5.35%. The net interest spread (FTE) in the first quarter of 2011 was 5.23% compared with 5.27% in the fourth quarter of 2010 the net result of a 0.11% decrease in earning asset yields, partially offset by lower cost of interest-bearing liabilities (down 0.07%). The margin contribution from noninterest bearing funding sources remained the same from the fourth quarter of 2010 to the first quarter of 2011.

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present, for the periods indicated, information regarding the Company’s consolidated average assets, liabilities and shareholders’ equity, the amount of interest income from average earning assets and the resulting annualized yields, and the amount of interest expense paid on average interest-bearing liabilities and the resulting annualized rate paid. Average loan balances include nonperforming loans. Interest income includes proceeds from loans on nonaccrual status only to the extent cash payments have been received and applied as interest income. Yields on securities and certain loans have been adjusted upward to reflect the effect of income which is exempt from federal income taxation at the current statutory tax rate (FTE).

Provision for Loan Losses

The Company manages credit costs by consistently enforcing conservative underwriting and administration procedures and aggressively pursuing collection efforts with troubled debtors. The Company recorded the purchased County loans at estimated fair value upon acquisition as of February 6, 2009. Further, County loans purchased from the FDIC are “covered” by loss-sharing agreements the Company entered with the FDIC. Due to the loss-sharing agreements and fair value recognition, the Company did not record a provision for loan losses during the first three months of 2011 related to such loans covered by the FDIC loss-sharing agreements. The Company recorded purchased Sonoma loans at estimated fair value upon acquisition as of August 20, 2010. Due to the fair value recognition, the Company did not record a provision for loan losses during the first three months of 2011 related to purchased Sonoma loans. In Management’s judgment, the acquisition date loan fair value discounts remaining at March 31, 2011 represent appropriate loss estimates for default risk inherent in the purchased loans. The Company provided $2.8 million for loan losses related to originated loans in the first quarter of 2011, the first and fourth quarters of 2010. The provision reflects Management’s assessment of credit risk in the originated loan portfolio for each of the periods presented. For further information regarding credit risk, the FDIC loss-sharing agreements, net credit losses and the allowance for loan losses, see Note 5 and the “Loan Portfolio Credit Risk” and “Allowance for Credit Losses” sections of this report.

Noninterest Income

The following table summarizes the components of noninterest income for the periods indicated.

Other noninterest income		1,313		884		844
Total	$	14,743	$	15,470	$	15,143

Noninterest income for the first quarter of 2011 declined by $727 thousand or 4.7% from the same period in 2010. Service charges on deposits decreased $1.2 million or 14.0% due to declines in fees charged on overdrawn and insufficient funds accounts (down $1.0 million) and deficit fees charged on analyzed accounts (down $232 thousand). New regulations over overdraft fees were adopted July 1, 2010 and limited the Bank’s ability to assess overdraft fees. Financial services commissions decreased $120 thousand due to the transition to a new provider for sales of mutual funds and annuities. Increases in trust fees and other noninterest income partially offset the decrease. A $112 thousand increase in trust fees was attributable to new trust accounts. Other noninterest income rose $429 thousand mostly due to a $400 thousand gain on sale of other assets.

In the first quarter of 2011, noninterest income decreased $400 thousand or 2.6% compared with the fourth quarter of 2010. Service charges on deposits decreased $463 thousand or 5.8% due to declines in fees charged on overdrawn and insufficient funds accounts (down $405 thousand) and deficit fees charged on analyzed accounts. Merchant credit card fees declined $256 thousand or 10.5% mainly due to seasonally lower transaction volumes. Financial services commissions decreased $135 thousand due to the transition to a new provider for sales of mutual funds and annuities. Offsetting the decrease was a $469 thousand increase in other noninterest income which mainly resulted from recoveries of charged-off purchased loans and ACH service fee income.

Noninterest expense in the three months ended March 31, 2011 include $679 thousand related to pre-integration costs for the acquired Sonoma Valley Bank, primarily outsourced data processing and personnel costs. SVB operations were fully integrated in February 2011. Noninterest expense decreased $708 thousand or 2.2% in the first quarter 2011 compared with the same period in 2010 primarily due to lower personnel expenses. Salaries and related benefits decreased $817 thousand or 5.1% primarily due to a reduction in regular salaries attributable to fewer employees and decreases in payroll taxes, incentives, bonuses and other benefits partially offset by annual merit increases and higher group health insurance costs. Equipment expense declined $118 thousand or 11.2% primarily due to lower repairs and maintenance expenses. The Company expects FDIC insurance assessments (including assessments for FICO bond debt service) of approximately $700 thousand in the second quarter 2011 based on application of new assessment rules effective April 1, 2011. Postage decreased $107 thousand or 22.5%. Occupancy expense increased $248 thousand or 6.6% primarily due to increases in rent. Outsourced data processing services expense increased $216 thousand or 9.6% mostly due to merger deconversion costs for Sonoma operations. Professional fees increased $187 thousand or 28.2% mainly due to higher legal expenses relating to delinquent loans and foreclosed assets.

In the first quarter of 2011, noninterest expense decreased $190 thousand or 0.6% compared with the fourth quarter of 2010. Equipment expense declined $158 thousand or 14.5% primarily due to lower repairs and maintenance expenses. Salaries and related benefits increased $176 thousand or 1.2% primarily due to higher payroll taxes and annual merit increases, offset in part by decreases in salaries, incentives, bonuses and other benefits. Outsourced data processing services expense increased mostly due to merger deconversion costs for Sonoma operations.

During the first quarter of 2011, the Company recorded income tax expense (FTE) of $13.2 million, compared with $14.1 million and $13.5 million for the first and fourth quarters of 2010, respectively. The current quarter provision represents an effective tax rate (FTE) of 37.2%, compared with 37.4% and 36.3% for the first and fourth quarters of 2010, respectively.

Loan Portfolio Credit Risk

The risk that loan customers do not repay loans granted by the Bank is the most significant risk to the Company. The Company closely monitors the markets in which it conducts its lending operations and follows a strategy to control exposure to loans with high credit risk. The Bank’s organization structure separates the functions of business development and loan underwriting; Management believes this segregation of duties avoids inherent conflicts of combining business development and loan approval. In measuring and managing credit risk, the Company adheres to the following practices.

• The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Those loans judged to carry higher risk attributes are referred to as “classified loans.” Classified loans receive elevated management attention to maximize collection.

• The Bank maintains two loan administration offices whose sole responsibility is to manage and collect classified loans.

Classified loans with higher levels of credit risk are further designated as “nonaccrual loans.” Management places loans on nonaccrual status when full collection of contractual interest and principal payments is in doubt. Interest previously accrued on loans placed on nonaccrual status is charged against interest income, net of estimated FDIC reimbursements under loss-sharing agreements. The Company does not accrue interest income on nonaccrual loans. Interest payments received on nonaccrual loans are applied to reduce the carrying amount of the loan unless the carrying amount is well secured by loan collateral or covered by FDIC loss-sharing agreements. “Nonperforming assets” include nonaccrual loans, loans 90 or more days past due and still accruing, and repossessed loan collateral.

On February 6, 2009, the Bank purchased loans and repossessed loan collateral of the former County Bank from the FDIC. This purchase transaction included loss-sharing agreements with the FDIC wherein the FDIC and the Bank share losses on the purchased assets. The loss-sharing agreements significantly reduce the credit risk of these purchased assets. In evaluating credit risk, Management separates the Bank’s total loan portfolio between those loans qualifying under the FDIC loss-sharing agreements (referred to as “purchased covered loans”) and loans not qualifying under the FDIC loss-sharing agreements (referred to as “purchased non-covered loans” and “originated loans”). At March 31, 2011, purchased covered loans totaled $660 million, or 23 percent of total loans, originated loans totaled $2.0 billion, or 70 percent of total loans and purchased non-covered loans totaled $187 million, or 7 percent of total loans.

The amount of gross interest income that would have been recorded if all nonaccrual purchased covered loans had been current in accordance with their original terms while outstanding was $688 thousand in the first quarter of 2011 and $1.3 million and $860 thousand in the first quarter and the fourth quarter of 2010, respectively. The amount of interest income that was recognized on nonaccrual purchased covered loans from cash payments made in the first quarter of 2011 was $503 thousand, compared with $1.5 million and $730 thousand for the first and fourth quarters of 2010, respectively. There were no cash payments received, which were applied against the book balance of nonaccrual purchased covered loans outstanding at March 31, 2011, March 31, 2010 and December 31, 2010 in the first quarter 2011, the first quarter 2010 and the fourth quarter 2010, respectively.

The amount of gross interest income that would have been recorded if all nonaccrual purchased non-covered loans had been current in accordance with their original terms while outstanding was $686 thousand in the first quarter of 2011 compared with $650 thousand in the fourth quarter of 2010. The amount of interest income that was recognized on nonaccrual purchased non-covered loans from cash payments made in the first quarter of 2011 was $171 thousand, compared with $24 thousand for the fourth quarter of 2010. There were no cash payments received, which were applied against the book balance of nonaccrual purchased non-covered loans outstanding at March 31, 2011 in the first quarter of 2011. The amount of cash payments received, which were applied against the book balance of nonaccrual purchased non-covered loans outstanding at December 31, 2010 totaled $510 thousand in the fourth quarter 2010.

The amount of gross interest income that would have been recorded if all nonaccrual originated loans had been current in accordance with their original terms while outstanding was $311 thousand in the first quarter of 2011, compared with $298 thousand and $307 thousand for the first and fourth quarters of 2010, respectively. The amount of interest income that was recognized on nonaccrual originated loans from cash payments made in the first quarter of 2011 was $118 thousand, compared with $131 thousand and $197 thousand for the first and fourth quarters of 2010, respectively. There were no cash payments received, which were applied against the book balance of nonaccrual originated loans outstanding at March 31, 2011, March 31, 2010 and December 31, 2010 in the first quarter 2011, the first quarter 2010 and the fourth quarter 2010, respectively.

The Company had no restructured loans as of March 31, 2011 and December 31, 2010.

Management believes the overall credit quality of the loan portfolio is reasonably stable; however, nonperforming assets could fluctuate from period to period. The performance of any individual loan can be affected by external factors such as the interest rate environment, economic conditions, and collateral values or factors particular to the borrower. No assurance can be given that additional increases in nonaccrual and delinquent loans will not occur in the future.

Purchased Covered Loans and Repossessed Loan Collateral (Purchased Covered Assets)

Purchased covered loans and repossessed loan collateral qualify under loss-sharing agreements with the FDIC. Under the terms of the loss-sharing agreements, the FDIC absorbs 80 percent of losses and shares in 80 percent of loss recoveries on the first $269 million in losses on purchased covered assets (“First Tier”), and absorbs 95 percent of losses and shares in 95 percent of loss recoveries if losses on purchased covered assets exceed $269 million (“Second Tier”). The term of the loss-sharing agreement on residential real estate assets is ten years, while the term for loss-sharing on non-residential real estate assets is five years with respect to losses and eight years with respect to loss recoveries.

The purchased covered assets are primarily located in the California Central Valley, including Merced County. This geographic area currently has some of the weakest economic conditions within California and has experienced significant declines in real estate values. Management expects higher loss rates on purchased covered assets than on originated assets.

The Bank recorded purchased covered assets at estimated fair value on the February 6, 2009 acquisition date. The credit risk discount ascribed to the $1.2 billion acquired loan and repossessed loan collateral portfolio was $161 million representing estimated losses inherent in the assets at the acquisition date. The Bank also recorded a related receivable from the FDIC in the amount of $129 million representing estimated FDIC reimbursements under the loss-sharing agreements.

The maximum risk to future earnings if First Tier losses exceed Management’s estimated $161 million in recognized losses under the FDIC loss-sharing agreements follows (dollars in thousands):

First Tier Loss Coverage	$	269,000
Less: Recognized credit risk discount		161,203
Exposure to under-estimated risk within First Tier		107,797
Bank loss-sharing percentage	20 percent
First Tier risk to Bank, pre-tax	$	21,559
First Tier risk to Bank, after-tax	$	12,494

Management has judged the likelihood of experiencing losses of a magnitude to trigger Second Tier FDIC reimbursement as remote. The Bank’s maximum after-tax exposure to Second Tier losses is $17 million as of March 31, 2011, which would be realized only if all covered assets at March 31, 2011 generated no future cash flows.

Purchased covered assets have declined since the acquisition date, and losses have been offset against the estimated credit risk discount. Purchased covered assets totaled $681 million at March 31, 2011, net of a credit risk discount of $57 million, compared to $715 million at December 31, 2010, net of a credit risk discount of $62 million. Purchased covered assets are evaluated for risk classification without regard to FDIC indemnification such that Management can identify purchased covered assets with potential payment problems and devote appropriate credit administration practices to maximize collections. Purchased covered assets classified without regard to FDIC indemnification totaled $203 million and $195 million at March 31, 2011 and December 31, 2010, respectively. FDIC indemnification limits the Company’s loss exposure to covered classified assets.

In Management’s judgment, the credit risk discount recognized for the purchased assets remains adequate as an estimate of credit risk inherent in purchased covered assets as of March 31, 2011. In the event credit risk deteriorates beyond that estimated by Management, losses in excess of the credit risk discount would be recognized as an expense, net of related FDIC loss indemnification.

Allowance for Credit Losses

The Company’s allowance for credit losses represents Management’s estimate of credit losses inherent in the loan portfolio. In evaluating credit risk for loans, Management measures loss potential of the carrying value of loans. As described above, payments on nonaccrual loans may be applied against the principal balance of the loans until such time as full collection of the remaining recorded balance is expected. Further, the carrying value of purchased loans includes fair value discounts assigned at the time of purchase under the provisions of FASB ASC 805, Business Combinations, and FASB ASC 310-30, Loans or Debt Securities with Deteriorated Credit Quality. Management determined the credit default fair value discounts assigned to purchased loans remained adequate as an estimate of credit losses inherent in purchased loans as of March 31, 2011. The allowance for credit losses represents Management’s estimate of credit losses in excess of these principal reductions.

- 41 -

The Company’s allowance for credit losses is maintained at a level considered adequate to provide for losses that can be estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall credit loss experience, the amount of past due, nonperforming loans and classified loans, FDIC loss-sharing coverage relative to purchased covered loan carrying amounts, recommendations of regulatory authorities, prevailing economic conditions and other factors. A portion of the allowance is specifically allocated to impaired loans whose full collectibility is uncertain. Such allocations are determined by Management based on loan-by-loan analyses. A second allocation is based in part on quantitative analyses of historical credit loss experience, in which criticized and classified credit balances identified through an independent internal credit review process are analyzed using a linear regression model to determine standard loss rates. The results of this analysis are applied to current criticized and classified loan balances to allocate the allowance to the respective segments of the loan portfolio. In addition, loans with similar characteristics not usually criticized using regulatory guidelines are analyzed based on the historical loss rates and delinquency trends, grouped by the number of days the payments on these loans are delinquent. Given currently weak economic conditions, Management is applying further analysis to consumer loans. Current levels of indirect automobile loan losses are compared to initial allowance allocations and, based on Management judgment, additional allocations are applied, if needed, to estimated losses. For residential real estate loans, Management is comparing ultimate loss rates on foreclosed residential real estate properties and applying such loss rates to nonaccrual residential real estate loans. Based on this analysis, Management exercises judgment in allocating additional allowance if deemed appropriate to estimated losses on residential real estate loans. Last, allocations are made to non-criticized and non-classified commercial loans based on historical loss rates and other statistical data.

The remainder of the allowance is considered to be unallocated. The unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but not reflected in the allocated allowance. It addresses additional qualitative factors consistent with Management’s analysis of the level of risks inherent in the loan portfolio, which are related to the risks of the Company’s general lending activity. Included in the unallocated allowance is the risk of losses that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in loan charge-off history (external factors). The external factors evaluated by the Company include: economic and business conditions, external competitive issues, and other factors. Also included in the unallocated allowance is the risk of losses attributable to general attributes of the Company’s loan portfolio and credit administration (internal factors). The internal factors evaluated by the Company include: loan review system, adequacy of lending Management and staff, loan policies and procedures, problem loan trends, concentrations of credit, and other factors. By their nature, these risks are not readily allocable to any specific loan category in a statistically meaningful manner and are difficult to quantify with a specific number. Management assigns a range of estimated risk to the qualitative risk factors described above based on Management’s judgment as to the level of risk, and assigns a quantitative risk factor from the range of loss estimates to determine the appropriate level of the unallocated portion of the allowance. Management considers the $37.0 million allowance for credit losses to be adequate as a reserve against originated credit losses as of March 31, 2011.

The following table presents the allocation of the allowance for credit losses:

	At March 31,					At December 31,
	2011					2010
	(In thousands)
			Originated Loans					Originated Loans
	Allocation of the		as Percent of Total			Allocation of the		as Percent of Total
	Allowance Balance		Originated Loans			Allowance Balance		Originated Loans
Commercial	$	9,847		23	%	$	9,878		23	%
Commercial real estate		10,359		38	%		9,607		38	%
Real estate construction		2,430		1	%		3,559		1	%

- 42 -

The allocation to loan portfolio segments changed from December 31, 2010 to March 31, 2011. The increase in allocation for originated commercial real estate loans was substantially attributable to an increase in classified originated loans, partially offset by lower commitments. The decrease in allocation to originated real estate construction loans reflects first quarter 2011 loan charge-offs. The allocation to originated consumer loans decreased due to Management’s judgment regarding the appropriate allocation based on recent charge-offs and delinquency trends. The unallocated portion of the allowance for credit losses increased $1.7 million from December 31, 2010 to March 31, 2011. The unallocated allowance is established to provide for probable losses that have been incurred, but not reflected in the allocated allowance. At March 31, 2011 and December 31, 2010, Management’s evaluations of the unallocated portion of the allowance for credit losses attributed significant risk levels to developing economic and business conditions ($1.8 million and $1.2 million, respectively), external competitive issues ($0.7 million and $0.6 million, respectively), internal credit administration considerations ($1.6 million and $1.2 million, respectively), and delinquency and problem loan trends ($2.8 million and $2.5 million, respectively). The change in the amounts allocated to the above qualitative risk factors was based upon Management’s judgment, review of trends in its originated loan portfolio, extent of migration of previously non-criticized originated loans to criticized status, levels of the allowance allocated to portfolio segments, and current economic conditions in its marketplace. Based on Management’s analysis and judgment, the amount of the unallocated portion of the allowance for credit losses was $9.4 million at March 31, 2011, compared to $7.7 million at December 31, 2010.

Asset/Liability and Market Risk Management

Asset/liability management involves the evaluation, monitoring and management of interest rate risk, market risk, liquidity and funding. The fundamental objective of the Company’s management of assets and liabilities is to maximize its economic value while maintaining adequate liquidity and a conservative level of interest rate risk.

Interest Rate Risk

Interest rate risk is a significant market risk affecting the Company. Interest rate risk results from many factors. Assets and liabilities may mature or reprice at different times. Assets and liabilities may reprice at the same time but by different amounts. Short-term and long-term market interest rates may change by different amounts. The timing and amount of cash flows of various assets or liabilities may shorten or lengthen as interest rates change. In addition, interest rates may have an impact on loan demand, demand for various deposit products, credit losses, and other sources of earnings such as account analysis fees on commercial deposit accounts and correspondent bank service charges.

In adjusting the Company’s asset/liability position, Management attempts to manage interest rate risk while enhancing the net interest margin and net interest income. At times, depending on expected increases or decreases in general interest rates, the relationship between long and short term interest rates, market conditions and competitive factors, Management may adjust the Company’s interest rate risk position in order to manage its net interest margin and net interest income. The Company’s results of operations and net portfolio values remain subject to changes in interest rates and to fluctuations in the difference between long and short term interest rates.

The Company’s asset and liability position ranged from “neutral” to slightly “asset sensitive” at March 31, 2011, depending on the interest rate assumptions applied to the simulation model employed by Management to measure interest rate risk. A “neutral” position results in similar amounts of change in interest income and interest expense resulting from application of assumed interest rate changes. A slightly “asset sensitive” position results in a slightly larger increase in interest income than in interest expense resulting from application of assumed interest rate changes. Management’s simulation modeling is currently biased toward rising interest rates. Management continues to monitor the interest rate environment as well as economic conditions and other factors it deems relevant in managing the Company’s exposure to interest rate risk.

Management assesses interest rate risk by comparing the Company’s most likely earnings plan with various earnings models using many interest rate scenarios that differ in the direction of interest rate changes, the degree of change over time, the speed of change and the projected shape of the yield curve. For example, using the current composition of the Company’s balance sheet and assuming no change in the federal funds rate and no change in the 10 year Constant Maturity Treasury Bond yield during the same period, earnings are not estimated to change by a meaningful amount compared to the Company’s most likely net income plan for the twelve months ending March 31, 2012. Using the current composition of the Company’s balance sheet and assuming an increase of 100 basis points (“bp”) in the federal funds rate and an increase of 60 bp in the 10 year Constant Maturity Treasury Bond yield during the same period, earnings are not estimated to change by a meaningful amount compared to the Company’s most likely net income plan for the twelve months ending March 31, 2012. Simulation estimates depend on, and will change with, the size and mix of the actual and projected balance sheet at the time of each simulation. In the current operating environment, Management’s objective is to maintain a “neutral” to slightly “asset sensitive” interest rate risk position. The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted with the approval of the Company’s Board of Directors.

Market Risk — Equity Markets

Equity price risk can affect the Company. As an example, any preferred or common stock holdings, as permitted by banking regulations, can fluctuate in value. Management regularly assesses the extent and duration of any declines in market value, the causes of such declines, the likelihood of a recovery in market value, and its intent to hold securities until a recovery in value occurs. Declines in value of preferred or common stock holdings that are deemed “other than temporary” could result in loss recognition in the Company’s income statement.

Fluctuations in the Company’s common stock price can impact the Company’s financial results in several ways. First, the Company has regularly repurchased and retired its common stock; the market price paid to retire the Company’s common stock can affect the level of the Company’s shareholders’ equity, cash flows and shares outstanding for purposes of computing earnings per share. Second, the Company’s common stock price impacts the number of dilutive equivalent shares used to compute diluted earnings per share. Third, fluctuations in the Company’s common stock price can motivate holders of options to purchase Company common stock through the exercise of such options thereby increasing the number of shares outstanding. Finally, the amount of compensation expense associated with share based compensation fluctuates with changes in and the volatility of the Company’s common stock price.

Market Risk — Other

Market values of loan collateral can directly impact the level of loan charge-offs and the provision for loan losses. Other types of market risk, such as foreign currency exchange risk and commodity price risk, are not significant in the normal course of the Company’s business activities.

Liquidity and Funding

The Company’s routine sources of liquidity are operating earnings, investment securities, consumer and other loans, deposits, and other borrowed funds. During the first quarter of 2011, the Company’s operating activities generated $32.5 million in liquidity providing most of the funds to pay common shareholders $10.5 million in dividends, fund $12.0 million in stock repurchases and reduce short-term borrowings by $13 million.

During the first quarter of 2010, operating cash flows provided $35.3 million to pay for $10.5 million in shareholder dividends and $4.8 million in repurchases of common stock. During the first quarter of 2010, investment securities provided $61.7 million in liquidity from paydowns and maturities to purchase securities of $53.5 million, and loans provided $89.8 million in liquidity from scheduled payments and maturities, net of loan fundings. Other sources of cash from investing activities include proceeds of $20 million under FDIC loss-sharing agreements.

The Company projects $62.2 million in additional liquidity from investment security paydowns and maturities during the three months ending June 30, 2011. At March 31, 2011, $280.6 million in residential collateralized mortgage obligations (“CMOs”) and residential mortgage backed securities (“MBSs”) were held in the Company’s investment portfolios. None of the CMOs or MBSs are backed by sub-prime mortgages. The residential CMOs and MBSs provided $31.2 million in liquidity from paydowns during the three months ended March 31, 2011. At March 31, 2011, indirect automobile loans totaled $405.0 million, which were experiencing stable monthly principal payments of approximately $16.5 million during the first quarter of 2011.

The Company held $1.3 billion in total investment securities at March 31, 2011. Under certain deposit, borrowing and other arrangements, the Company must hold and pledge investment securities as collateral. At March 31, 2011, such collateral requirements totaled approximately $883.1 million. At March 31, 2011, $741.6 million of the Company’s investment securities were classified as “available-for-sale”, and as such, could provide additional liquidity if sold, subject to the Company’s ability to meet continuing collateral requirements.

In addition, at March 31, 2011, the Company had customary lines for overnight borrowings from other financial institutions in excess of $700 million, under which $-0- million was outstanding. Additionally, the Company has access to borrowing from the Federal Reserve. The Company’s short-term debt rating from Fitch Ratings is F1. The Company’s long-term debt rating from Fitch Ratings is A with a stable outlook. Management expects the Company could access additional long-term debt financing if desired. In Management’s judgment, the Company’s liquidity position is strong and asset liquidations or additional long-term debt are considered unnecessary to meet the ongoing liquidity needs of the Company.

- 44 -

The Company anticipates maintaining its cash levels in the remainder of 2011. Loan demand from credit-worthy borrowers will be dictated by economic and competitive conditions in the remainder of 2011. The Company aggressively solicits non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to changes in interest rates. The growth of deposit balances is subject to heightened competition, the success of the Company’s sales efforts, delivery of superior customer service, new regulations and market conditions. Changes in interest rates, most notably rising interest rates, could impact deposit volumes in the future. Depending on economic conditions, interest rate levels, and a variety of other conditions, deposit growth may be used to fund loans, to reduce borrowings or purchase investment securities. However, due to concerns such as uncertainty in the general economic environment, competition and political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue subject to the Board’s discretion and continuing evaluation of capital levels, earnings, asset quality and other factors.

Westamerica Bancorporation (“Parent Company”) is a separate entity and apart from Westamerica Bank (“Bank”) and must provide for its own liquidity. In addition to its operating expenses, the Parent Company is responsible for the payment of dividends declared for its shareholders, and interest and principal on outstanding debt. Substantially all of the Parent Company’s revenues are obtained from subsidiary dividends and service fees. Payment of dividends to the Parent Company by the Bank is limited under California law. The amount that can be paid in any calendar year, without prior approval from the state regulatory agency, cannot exceed the net profits (as defined) for the preceding three calendar years less distributions in that period. The Company believes that such restriction will not have an impact on the Parent Company’s ability to meet its ongoing cash obligations.

Capital Resources

The Company has historically generated high levels of earnings, which provides a means of raising capital. The Company’s net income as a percentage of average common equity (“return on common equity” or “ROE”) was 16.6% (annualized) in the first quarter of 2011, 18.1% in 2010 and 25.8% in 2009. The Company also raises capital as employees exercise stock options, which are awarded as a part of the Company’s executive compensation programs to reinforce shareholders’ interests in the Management of the Company. Capital raised through the exercise of stock options totaled $3.0 million in the first quarter of 2011, $16.7 million in 2010 and $9.6 million in 2009.

The Company paid dividends totaling $10.5 million in the first quarter of 2011, $42.1 million in 2010 and $41.1 million in 2009, which represent dividends per share of $0.36, $1.44 and $1.41, respectively. The Company’s earnings have historically exceeded dividends paid to shareholders. The amount of earnings in excess of dividends gives the Company resources to finance growth and maintain appropriate levels of shareholders’ equity. In the absence of profitable growth opportunities, the Company has repurchased and retired its common stock as another means to return capital to shareholders. The Company repurchased and retired 239 thousand shares of common stock valued at $12.0 million in the first quarter of 2011, 533 thousand shares valued at $28.7 million in 2010 and 42 thousand shares valued at $2.0 million in 2009. Share repurchases were restricted to amounts conducted in coordination with employee benefit programs under the terms of the February 13, 2009 issuance of preferred stock to the Treasury; such restrictions were removed with full redemption of the preferred stock in November 2009.

The Company’s primary capital resource is shareholders’ equity, which increased $5.6 million or 1.0% during the first quarter 2011 primarily due to $22.4 million in net income and $3.0 million in issuance of stock in connection with exercises of employee stock options, offset by $10.5 million in dividends paid and $12.0 million in stock repurchases.

Capital to Risk-Adjusted Assets

The following summarizes the ratios of capital to risk-adjusted assets for the Company on the dates indicated:

										Minimum			Well-capitalized
	At March 31,						At December 31,			Regulatory			by Regulatory
	2011			2010			2010			Requirement			Definition
Tier I Capital		14.47	%		13.91	%		14.21	%		4.00	%		6.00	%
Total Capital		15.79	%		15.21	%		15.50	%		8.00	%		10.00	%
Leverage ratio		8.68	%		8.21	%		8.44	%		4.00	%		5.00	%

The risk-based capital ratios increased at March 31, 2011 compared with March 31, 2010, due to higher retained earnings, partially offset by an increase in risk-weighted assets. The risk-based capital ratios increased at March 31, 2011, compared with December 31, 2010, due to increased retained earnings and a decrease in risk-weighted assets. As described in Note 10, the Company intends to retire a $10 million subordinated note in August 2011. Such debt qualifies as regulatory capital. Management intends to use cash earnings to retire the debt. FDIC-covered assets are included in the 20% risk-weight category until the loss-sharing agreements terminate; the residential loss-sharing agreement expires February 6, 2019 and the non-residential loss-sharing agreement expires (as to losses) February 6, 2014.

The risk-based capital ratios increased at March 31, 2011, compared with March 31, 2010 due to higher retained earnings, partially offset by an increase in risk-weighted assets. The risk-based capital ratios increased at March 31, 2011, compared with December 31, 2010, due to increased retained earnings and a decrease in risk-weighted assets.

The Company and the Bank intend to maintain regulatory capital in excess of the highest regulatory standard, referred to as “well capitalized.” The Company and the Bank routinely project capital levels by analyzing forecasted earnings, credit quality, securities valuations, shareholder dividends, asset volumes, share repurchase activity, stock option exercise proceeds, and other factors. Based on current capital projections, the Company and the Bank expect to maintain regulatory capital levels exceeding the “well capitalized” standard and pay quarterly dividends to shareholders. No assurance can be given that changes in capital management plans will not occur.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be undertaken with the approval of the Company’s Board of Directors. Interest rate risk as discussed above is the most significant market risk affecting the Company. Other types of market risk, such as foreign currency exchange risk, equity price risk and commodity price risk, are not significant in the normal course of the Company’s business activities.

Item 4. Controls and Procedures

The Company’s principal executive officer and principal financial officer have evaluated the effectiveness of the Company’s “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, as of March 31, 2011. Based upon their evaluation, the principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time period specified in the Securities and Exchange Commission’s rules and forms and are effective in ensuring that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is accumulated and communicated to Management, including the chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure. The evaluation did not identify any change in the Company’s internal control over financial reporting that occurred during the quarter ended March 31, 2011 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 1A. Risk Factors

The Company’s Form 10-K as of December 31, 2010 includes detailed disclosure about the risks faced by the Company’s business; such risks have not materially changed since the Form 10-K was filed, except as described below:

Japanese Disaster

During the first quarter 2011, Japan experienced a devastating earthquake and resultant tsunami. The tsunami reached the California coastline, but caused limited damage. The Company’s loan customers are generally small businesses and professionals whose business activities are primarily located in Northern and Central California. These customers in the aggregate have some, but not a significant amount of reliance on trade with Asian countries. Management does not expect any significant impact on the Company’s financial results due to this disaster. However, additional shocks could occur, including, but not limited to harmful radiation from the damaged nuclear power plants. Further, economic imbalances are likely to exist such as heightened demand for non-nuclear sources of energy for Japan, supply chain disruptions affecting international manufacturing processes, food shortages, demand for liquidity, and other possible repercussions. These imbalances could affect asset values such as, but not limited to, investment securities, energy and commodities. Significant changes in assets values could impact the financial condition of the Company.

The Company repurchases shares of its common stock in the open market to optimize the Company’s use of equity capital and enhance shareholder value and with the intention of lessening the dilutive impact of issuing new shares to meet stock performance, option plans, and other ongoing requirements.

Shares were repurchased during the first quarter of 2011 pursuant to a program approved by the Board of Directors on August 26, 2010, authorizing the purchase of up to 2 million shares of the Company’s common stock from time to time prior to September 1, 2011.
