                        FORWARD-LOOKING STATEMENTS

This report on Form 10-Q contains forward-looking statements about Westamerica
Bancorporation for which it claims the protection of the safe harbor provisions
contained in the Private Securities Litigation Reform Act of 1995. These
forward-looking statements are based on Management's current knowledge and
belief and include information concerning the Company's possible or assumed
future financial condition and results of operations. A number of factors,
some of which are beyond the Company's ability to predict or control, could
cause future results to differ materially from those contemplated. These factors
include but are not limited to (1) a slowdown in the national and California
economies; (2) fluctuations in asset prices including, but not limited to,
stocks, bonds, real estate, and commodities; (3) economic uncertainty created by
terrorist threats and attacks on the United States, the actions taken in
response, and the uncertain effect of these events on the national and regional
economies; (4) changes in the interest rate environment; (5) changes in the
regulatory environment; (6) significantly increasing competitive pressure in the
banking industry; (7) operational risks including data processing system
failures or fraud; (8) the effect of acquisitions and integration of acquired
businesses; (9) volatility of rate sensitive deposits and investments; (10)
asset/liability management risks and liquidity risks; (11) changes in liquidity
levels in capital markets; and (12) changes in the securities markets. The
reader is directed to the Company's annual report on Form 10-K for the year
ended December 31, 2006, for further discussion of factors which could affect
the Company's business and cause actual results to differ materially from those
expressed in any forward-looking statement made in this report. The Company
undertakes no obligation to update any forward-looking statements in this
report.

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, 2007 and 2006 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, 2006.

Note 2: Significant Accounting Policies.

Certain accounting policies underlying the preparation of these financial
statements require Management to make estimates and judgments. These estimates
and judgments may affect reported amounts of assets and liabilities, revenues
and expenses, and disclosures of contingent assets and liabilities. The most
significant of these involve the Allowance for Loan Losses, which is 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, 2006.

In July 2006, the Financial Accounting Standards Board issued Financial
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 supplements FAS 109, "Accounting for Income Taxes," by defining the
threshold for recognizing tax benefits in the financial statements as "more
likely than not" to be sustained by the applicable taxing authority. The benefit
recognized for a tax position that meets the "more likely than not" criterion is
measured based on the largest benefit that is more than 50% likely to be
realized, taking into consideration the amounts and probabilities of the
outcomes upon settlement. The Company adopted the provisions of FASB
Interpretation No.48 Accounting for Uncertainty in Income Taxes, on January 1,
2007.

In September 2006, the SEC staff issued Staff Accounting Bulletin No. 108,
"Considering the Effects of Prior Year Misstatements when Quantifying
Misstatements in Current Year Financial Statements" (SAB 108). SAB 108 was
issued in order to eliminate the diversity of practice surrounding how public
companies quantify financial statement misstatements. Prior to SAB 108, the
Company had historically focused on the impact of misstatements on the income
statement, including the reversing effect of prior year misstatements. With a
focus on the income statement, the Company's analysis could lead to the
accumulation of misstatements in the balance sheet. In applying SAB 108, the
Company must also consider any accumulated misstatements in the balance sheet.
SAB 108 permitted companies to initially apply its provisions by recording the
cumulative effect of misstatements as adjustments to the balance sheet as of the
first day of the fiscal year, with an offsetting adjustment recorded to retained
earnings, net of tax. In applying SAB 108, the Company made an adjustment to
reduce other liabilities by $3 million. The $3 million overstatement of other
liabilities accumulated over seventeen years, as the liability accrued for
stock-based compensation exceeded the amount paid to employees. These
misstatements had not previously been material to the income statements for any
of those prior periods. Comparative amounts as of March 31, 2006 have been
adjusted to reflect adoption of SAB 108 as follows (in thousands):




                                                    As

    Liability for interest, taxes
      and other expenses                       $65,326      ($3,000)     $62,326
    Interest receivable and
      other assets                             152,644       (1,244)     151,400
    Retained earnings                           85,261        1,756       87,017



In September 2006, the FASB issued FAS 157, Fair Value Measurements, which
defines fair value, establishes a framework for measuring fair value in
generally accepted accounting principles (GAAP), and expands disclosures about
fair value measurements. FAS 157 applies under other accounting pronouncements
that require or permit fair value measurements, the FASB having previously
concluded in those accounting pronouncements that fair value is the relevant
measurement attribute. FAS 157 is effective for the year beginning January 1,
2008. The Company is currently evaluating the effects of adopting FAS 157 on its
consolidated financial statements.

In February 2007, the FASB issued FASB Statement No. 159, The Fair Value Option
for Financial Assets and Financial Liabilities -- Including an Amendment of FASB
Statement No. 115 ("FAS 159"). This standard permits entities to choose to
measure many financial assets and liabilities and certain other items at fair
value. An enterprise will report unrealized gains and losses on items for which
the fair value option has been elected in earnings at each subsequent reporting
date. The fair value option may be applied on an instrument-by-instrument basis,
with several exceptions, such as those investments accounted for by the equity
method, and once elected, the option is irrevocable unless a new election date
occurs. The fair value option can be applied only to entire instruments and not
to portions thereof. FAS 159 is effective as of the beginning of an entity's
first fiscal year beginning after November 15, 2007. The Company is currently
evaluating the effects of adopting FAS 159 on its consolidated financial
statements.

Note 3: Goodwill and Other 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 three months ended March 31, 2007. 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 first quarter of
2007, no such adjustments were recorded.




  The changes in the carrying value of goodwill were ($ in thousands):

Note 4: Stock Options

The Company grants stock options and restricted performance shares to employees
in exchange for employee services, pursuant to the shareholder-approved 1995
Stock Option Plan, which was amended and restated in 2003. Stock options are
granted with an exercise price equal to the fair market value of the related
common stock and generally became exercisable in equal annual installments over
a three-year period with each installment vesting on the anniversary date of the
grant. Each stock option has a maximum ten-year term. A restricted performance
share grant becomes vested after three years of being awarded, provided the
Company has attained its performance goals for such three-year period.

The Company applies the Roll-Geske option pricing model (Modified Roll) to
determine grant date fair value of stock option grants. This model modifies the
Black-Scholes Model to take into account dividends and American options. The
following weighted average assumptions were used in the option pricing to value
stock options granted in the periods indicated:

Note 6: Accounting for Uncertainty in Income Taxes

The Company adopted the provisions of FASB Interpretation No.48 Accounting for
Uncertainty in Income Taxes, on January 1, 2007. As a result of the
implementation of Interpretation 48, the Company did not recognize any increase
or decrease for unrecognized tax benefits. A reconciliation of the beginning and
ending amount of unrecognized tax benefits is as follows (in thousands):

                                                                    =============



The Company does not anticipate any significant increase or decrease in
unrecognized tax benefits during 2007. Unrecognized tax benefits at January 1,
2007 and March 31, 2007 include accrued interest and penalties of $137 thousand.
If recognized, the entire amount of the unrecognized tax benefits would affect
the effective tax rate.

The Company classifies interest and penalties as a component of the provision
for income taxes. The tax years ended December 31, 2006, 2005, 2004 and 2003
remain subject to examination by the Internal Revenue Service. The tax years
ended December 31, 2006, 2005, 2004, 2003, and 2002 remain subject to
examination by the California Franchise Tax Board. Included in the balance at
January 1, 2007 is $1.6 million in tax positions for which the ultimate
deductibility is uncertain. The deductibility of these tax positions will be
determined through examination by the appropriate tax jurisdictions or the
expiration of the tax statute of limitations.

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

Westamerica Bancorporation and subsidiaries (the "Company") reported first
quarter 2007 net income of $23.6 million or $.76 diluted earnings per share.
These results compare to net income of $26.1 million or $.81 diluted earnings
per share and $24.0 million or $.77 diluted earnings per share, respectively,
for the first and fourth quarters of 2006. The first quarter of 2007 included
$822 thousand in tax-exempt company owned life insurance proceeds, representing
$0.02 earnings per diluted share.

Following is a summary of the components of net income for the periods indicated
(dollars in thousands except per share data):




                                                                                Three months ended

Net income for the first quarter of 2007 was $2.5 million or 9.8% less than the
same quarter of 2006, primarily due to lower net interest income, partially
offset by higher noninterest income, lower noninterest expense and a lower
income tax provision. The decrease in net interest income (FTE) (down $7.1
million or 13.1%) was primarily attributable to lower average earning assets and
higher funding costs, partially offset by higher yields on interest-earning
assets. The loan loss provision decreased $75 thousand or 50.0% from a year ago,
reflecting Management's assessment of credit risk for the loan portfolio.
Noninterest income increased $1.6 million or 12.0% mainly due to higher service
charges on deposit accounts and $822 thousand in life insurance proceeds.
Noninterest expense decreased $819 thousand or 3.2% mostly due to lower
personnel costs. The provision for income taxes (FTE) declined $2.0 million or
12.5% largely due to lower pretax income and tax-exempt nature of gain on
company owned life insurance.

Comparing the first three months of 2007 to the prior quarter, net income
declined $388 thousand or 1.6%, due to lower net interest income (FTE), offset
by higher noninterest income, decreases in noninterest expense and the provision
for income taxes. The lower net interest income (FTE) was caused by higher
funding costs, the effect of two less accrual days and lower average earning
assets, partially offset by higher yields on those assets. Noninterest income
increased $1.5 million or 11.1% largely due to higher fee income earned on
deposit accounts and life insurance proceeds. Noninterest expense increased $172
thousand or 0.7%. The income tax provision (FTE) decreased mainly due to lower
earnings and tax-exempt nature of life insurance proceeds.

    Average earning assets                                            $4,287,431   $4,606,178   $4,366,676

Approximately eighty percent of the Company's revenue (FTE) is derived from net
interest income, or the difference between interest income earned on loans and
investments and interest expense paid on interest-bearing deposits and
borrowings. Net interest income (FTE) during the first quarter of 2007 decreased
$7.1 million or 13.1% from the same period in 2006 to $46.9 million, mainly
due to lower average earning assets (down $319 million) and rates on
interest-bearing liabilities (up 64 basis points ("bp")) rising more rapidly
than yields on earning assets (up 11 bp). Interest deposit competition within
the banking industry has caused deposit costs to rise, while competitive rates
on loans have not changed significantly.

Comparing the first quarter of 2007 with the previous quarter, net interest
income (FTE) declined $2.1 million or 4.3%, primarily due to lower average
earning assets (down 79.2 million), the effect of two less accrual days, higher
average federal funds purchased (up $79.1 million), and higher rates on
interest-bearing liabilities (up 15 bp), partially offset by higher yields on
earning assets (up 5 bp).

Interest and Fee Income

Interest and fee income (FTE) for the first quarter of 2007 declined $3.5
million or 5.1% from the same period in 2006. The decrease was caused by lower
average earning assets (down $318.7 million), partially offset by higher yields
on those assets (up 11 bp) and higher loan fee income (up $97 thousand).


Page 14

The average yield on the Company's earning assets increased from 6.00% in the
first quarter of 2006 to 6.11% in the same period in 2007. The composite yield
on loans rose 14 bp to 6.66% primarily due to increases in the average yields on
construction loans (up 139 bp), indirect automobile loans (up 45 bp), direct
consumer loans (up 95 bp), residential real estate loans (up 10 bp) and
commercial loans (up 7 bp).

The investment portfolio yield increased 12 bp to 5.35%, caused by increases in
the average yield on corporate and other securities (up 109 bp) and U.S.
government sponsored entity obligations (up 24 bp). Partially offsetting these
increases were a 4 bp decrease in the average yield on municipal securities.

Average earning assets for the first quarter of 2007 declined $319 million
compared to the same period in 2006. The loan portfolio decreased $96 million
mainly due to declines in commercial loans (down $67 million), commercial real
estate loans (down $22 million) and direct consumer loans (down $13 million),
partially offset by a $21 million increase in average indirect automobile loans.

The Company has allowed the investment portfolio to decline due to the current
interest rate environment, which has very narrow spreads between current
interest rates on similar securities and on incremental funding sources.

Average investments declined $223 million for the first quarter of 2007 compared
to the same period in 2006 due to decreased average balances of mortgage backed
securities and collateralized mortgage obligations (down $133 million),
municipal securities (down $35 million), U.S. government sponsored entity
obligations (down $29 million) and corporate and other securities (down $26
million).

Comparing the first quarter of 2007 with the previous quarter, interest and fee
income (FTE) was down $1.5 million or 2.2%. The decrease largely resulted from a
lower volume of average earning assets, partially offset by rising yields on
those assets.

The average yield on earning assets for the first three months of 2007 was 6.11%
compared with 6.07% in the fourth quarter of 2006. The loan portfolio yield for
the first quarter of 2007 compared with the previous quarter was higher by 5 bp,
due to increases in yields on commercial real estate loans (up 9 bp), indirect
automobile loans (up 9 bp) and residential real estate loans (up 5 bp).

The investment portfolio yield rose by 6 bp. The increase resulted from higher
average yields on corporate and other securities (up 75 bp) and municipal
securities (up 4 bp).

Average earning assets decreased $79 million or 1.8% for the first quarter of
2007 compared with the previous quarter due to a $52 million decline in the
investment portfolio and a $28 million decrease in the loan portfolio. Lower
average investment balances were mainly attributable to mortgage backed
securities and collateralized mortgage obligations (down $28 million), municipal
securities (down $14 million) and corporate and other securities (down $9
million).

The loan portfolio decline was primarily due to decreases in average balances of
commercial loans (down $18 million), commercial real estate loans (down $15
million) and residential real estate loans (down $8 million), offset by an $18
million increase in the average balance of indirect automobile loans.

Interest Expense

Interest expense in the first quarter of 2007 increased $3.6 million or 24.8%
compared with the same period in 2006. The increase was attributable to higher
rates paid on the interest-bearing liabilities, partially offset by lower
average interest-bearing liabilities.

The average rate paid on interest-bearing liabilities increased from 1.82% in
the first quarter of 2006 to 2.46% in 2007. The average rate on federal funds
purchased rose 80 bp and rates on deposits increased as well, including those on
certificates of deposit ("CDs") over $100 thousand, which rose 106 bp; on retail
CDs, which went up by 89 bp; and on preferred money market savings accounts,
which rose an average of 220 bp.

Interest-bearing liabilities decreased $244 million or 7.6% for the first
quarter of 2007 over the same period of 2006 due to a highly competitive
environment for deposits. A $357 million decline in deposits were mostly due to
lower average balances of money market savings (down $151 million), money market
checking accounts (down $65 million), regular savings (down $46 million), retail
CDs (down $35 million). Partially offsetting these declines was a $48 million
increase in federal funds purchased.

Comparing the first quarter of 2007 with the previous quarter, interest expense
rose $628 thousand or 3.6%, due to higher rates paid on interest-bearing
liabilities, partially offset by lower average interest-bearing liabilities.

Rates paid on liabilities averaged 2.46% during the first three months of 2007
compared with 2.32% in the fourth quarter of 2006. The most significant rate
increases were preferred money market savings accounts (up 80 bp), CDs over $100
thousand which rose 9 bp and retail CDs which increased by 11 bp.

Average interest-bearing liabilities declined $14 million or 0.5% over the
fourth quarter of 2006. Average deposits declined $126 million or 3.6% mainly
due to decreases in average balances of money market savings accounts (down $36
million), CDs over $100 thousand (down $21 million), and regular savings (down
$11 million). A $79 million increase in average federal funds purchased
partially offset these decreases.

In all periods, the Company has attempted to continue to reduce high-rate time
deposits while increasing the balances of more profitable, lower-cost
transaction accounts in order to minimize the cost of funds. Lower-cost
transaction accounts experience seasonal trends primarily due to customer income
and property tax payments, with the most significant deposit outflows occurring
in the first calendar quarter of each year.

During the first quarter of 2007, the net interest margin declined 32 bp
compared with the same period in 2006. Rates paid on interest-bearing
liabilities increased faster than the yields on earning assets, resulting in a
53 bp decline in net interest spread. The decline in the net interest spread was
mitigated by the higher net interest margin contribution from noninterest
bearing funding sources. While the average balance of these sources decreased
$85 million or 6.3%, their value increased 21 bp, from 55 bp in the first
quarter of 2006 to 76 bp in the first quarter of 2007, because of the higher
earning asset yields at which they could be invested.

The net interest margin declined by 8 bp when compared with the fourth quarter
of 2006. Earning asset yields increased 4 bp, however, the cost of
interest-bearing liabilities rose by 14 bp, resulting in a 10 bp decrease in the
interest spread. Although noninterest bearing funding sources decreased $62
million or 4.6%, their margin contribution increased by 2 bp.

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
yields, and the amount of interest expense paid on interest-bearing liabilities.
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) (dollars in
thousands).

    (1) Interest and rates calculated on a fully taxable equivalent basis using the
    current statutory federal tax rate.
    (2) Net interest spread represents the average yield earned on earning assets
    minus the average rate paid on interest-bearing liabilities.
    (3) Net interest margin is computed by calculating the difference between
    interest income and expense (annualized), divided by the average balance of
    earning assets.

Provision for Credit Losses

The level of the provision for credit losses during each of the periods
presented reflects the Company's continued efforts to manage credit costs by
enforcing underwriting and administration procedures and aggressively pursuing
collection efforts with troubled debtors. The Company provided $75 thousand for
credit losses in the first quarter of 2007. In the fourth quarter of 2006, the
provision for credit losses was $75 thousand, of which $70 thousand was
allocated to loan losses and $5 thousand was allocated to unfunded loan
commitments. In the first quarter of 2006, the Company provided $150 thousand
for credit losses. The provision reflects the Company's loss experience and
Management's assessment of credit risk in the loan portfolio for each of the
periods presented. For further information regarding net credit losses and the
allowance for loan losses, see the "Classified Loans" section of this report.

Noninterest income for the first quarter of 2007 rose by $1.6 million or 12.0%
from the same period in 2006. Service charges on deposit accounts increased due
to management efforts to increase deposit accounts and minimize service charge
waivers. Service charges on deposit accounts increased $445 thousand or 6.3%
mainly due to a $689 thousand increase in overdraft fees, partially offset by
declines in deficit fees charged on analyzed accounts (down $160 thousand or
10.2%) and retail and business checking account service fees. Other noninterest
income was higher by $1.0 million or 68.4% mostly due to $822 thousand in life
insurance proceeds.

In the first quarter of 2007, noninterest income increased $1.5 million or 11.1%
compared with the previous quarter. Service charges on deposit accounts rose
$538 thousand or 7.7% mostly due to a $315 thousand increase in overdraft fees
and increased deficit fees charged on analyzed accounts. Other noninterest
income increased $1.2 million mainly due to $822 thousand in life insurance
proceeds. Merchant credit card income declined $203 thousand or 7.7% primarily
due to seasonally lower credit card draft volumes.

Noninterest expense decreased $819 thousand or 3.2% in the first quarter of 2007
compared with the same period in 2006. The largest decline was salaries and
incentives, which was down $690 thousand or 5.2% mainly due to a $294 thousand
decrease in regular salaries and a $341 thousand decrease in employee benefit
costs. The decrease in regular salaries was attributable to the effect of a
smaller workforce through attrition, partially offset by annual merit increases
to continuing staff. Equipment expense decreased $128 thousand or 10.1%
primarily due to a $136 thousand decline in repair and maintenance expense.
Other noninterest expense rose $141 thousand or 9.0% mostly due to increases in
amortization of investments in low-income housings as tax benefits are realized
and internet banking expense.


Page 22

In the first three months of 2007, noninterest expense rose $172 thousand or
0.7% compared with the fourth quarter of 2006. Salaries and related benefits
rose $163 thousand or 1.3% mainly due to a seasonal increase in payroll taxes,
increases in regular salaries resulting from annual merit increases, and an
increase in the cost of providing employee medical benefits. Other noninterest
expense increased $265 thousand or 18.3% mainly because the prior quarter
included credits to correct overbillings for the debit card network fees.
Offsetting these increases were decreases in operational losses (down $160
thousand) and professional fees (down $119 thousand or 19.4%). The decline in
operational losses were attributable to a $117 thousand decrease in sundry
losses. Lower professional fees resulted from decreases in legal and accounting
fees.


Provision for Income Tax

During the first quarter of 2007, the Company recorded income tax expense (FTE)
of $13.9 million, compared with $15.9 million and $14.3 million for the first
and fourth quarters of 2006, respectively. The current quarter provision
represents an effective tax rate (FTE) of 37.1%, compared with 37.8% and 37.3%
for the first and fourth quarters of 2006, respectively. The effective tax rate
for the first quarter 2007 was reduced primarily due to tax-exempt company owned
life insurance proceeds. The effective tax rate for the fourth quarter was
reduced primarily due to tax refunds and other tax items.

The tax provisions and effective tax rates fluctuated due to the relative level
of tax- exempt income from municipal investments and loans to the level of
pretax income, and tax-free life insurance proceeds of $822 thousand in the
first quarter of 2007.


Classified Loans and Other Real Estate Owned

The Company closely monitors the markets in which it conducts its lending
operations and continues its strategy to control exposure to loans with high
credit risk and to increase diversification of earning assets. Loan reviews are
performed using grading standards and criteria similar to those employed by bank
regulatory agencies. Loans receiving lesser grades fall under the "classified"
category, which includes all nonperforming and potential problem loans, and
receive an elevated level of attention to ensure collection. Other real estate
owned is recorded at the lower of cost or net realizable value (market value
less disposition costs).

The following is a summary of classified loans and other real estate owned on
the dates indicated (dollars in thousands):

Classified loans include loans graded "Substandard", "Doubtful" and "Loss" using
regulatory guidelines. At March 31, 2007, $18.1 million of loans are graded
"Substandard" or 98.2% of total classified loans. Classified loans at March 31,
2007, decreased $10.4 million or 36.1% from a year ago. The decline resulted
from 11 loan payoffs totaling $12.0 million, five upgrades totaling $5.3
million, two charge-offs and a transfer to OREO, partially offset by 13
downgrades totaling $11.1 million. A $1.7 million or 8.6% decrease in classified
loans from December 31, 2006 was generally due to three upgrades totaling $1.1
million and a chargeoff, partially offset by three downgrades totaling $1.3
million. Other real estate owned at March 31, 2007 and December 31, 2006 was
$647 thousand compared with none a year ago because collateral for one
commercial real estate loan was foreclosed in the second quarter of 2006.


Nonperforming Loans

Nonperforming loans include nonaccrual loans and loans 90 days past due as to
principal or interest and still accruing. Loans are placed on nonaccrual status
when they become 90 days or more delinquent, unless the loan is well secured and
in the process of collection. Interest previously accrued on loans placed on
nonaccrual status is charged against interest income. In addition, loans secured
by real estate with temporarily impaired values and commercial loans to
borrowers experiencing financial difficulties are placed on nonaccrual status
even though the borrowers continue to repay the loans as scheduled. Such loans
are classified as "performing nonaccrual" and are included in total
nonperforming assets. When the ability to fully collect nonaccrual loan
principal is in doubt, cash payments received are applied against the principal
balance of the loan until such time as full collection of the remaining recorded
balance is expected. Any subsequent interest received is recorded as interest
income on a cash basis.

Nonaccrual loans decreased $335 thousand during the three months ended March 31,
2007. Ten loans comprised the $4.8 million nonaccrual loans as of March 31,
2007. Six of those loans were on nonaccrual status throughout the first quarter
2007, while four of the loans were placed on nonaccrual status during the
quarter. The Company actively pursues full collection of nonaccrual loans.

The Company had no "sub-prime" loans as of March 31, 2007, December 31, 2006 and
March 31, 2006. Of the loans 90 days past due and still accruing at March 31,
2007, $-0- and $60 thousand were residential real estate loans and automobile
loans, respectively.

The Company had no restructured loans as of March 31, 2007, December 31,
2006 and March 31, 2006.

The amount of gross interest income that would have been recorded for nonaccrual
loans for the three months ended March 31, 2007, if all such loans had been
current in accordance with their original terms, was $110 thousand, compared to
$120 thousand and $118 thousand, respectively, for the first and fourth quarters
of 2006.

The amount of interest income that was recognized on nonaccrual loans from all
cash payments, including those related to interest owed from prior years, made
during the three months ended March 31, 2007, totaled $119 thousand, compared to
$60 thousand and $171 thousand, respectively, for the first and fourth quarters
of 2006. These cash payments represent annualized yields of 10.14% for first
three months of 2007 compared to 4.15% and 13.30%, respectively, for the first
and the fourth quarter of 2006.

Total cash payments received, including those recorded in prior years, which
were applied against the book balance of nonaccrual loans outstanding at March
31, 2007, totaled approximately $4 thousand, compared with $32 thousand and $0
for the first and the fourth quarters of 2006, respectively.

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


Allowance for Credit Losses

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, recommendations of regulatory authorities,
prevailing economic conditions and other factors. A portion of the allowance is
specifically allocated to impaired and other identified 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 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 reserve 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. Last, allocations are made to general loan
categories based on commercial office vacancy rates, mortgage loan foreclosure
trends, agriculture commodity prices, and levels of government funding. The
remainder of the reserve is considered to be unallocated and is established at a
level considered necessary based on relevant economic conditions and available
data, including unemployment statistics, unidentified economic and business
conditions, the quality of lending management and staff, credit quality trends,
concentrations of credit, and changing underwriting standards due to external
competitive factors. Management considers the $58.6 million allowance for credit
losses to be adequate as a reserve against losses as of March 31, 2007.

Asset and Liability Management

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 is the most 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 remaining maturity of various assets or
liabilities may shorten or lengthen as interest rates change. In addition,
interest rates may have an indirect impact on loan demand, credit losses, and
other sources of earnings such as account analysis fees on commercial deposit
accounts, official check fees and correspondent bank service charges.

In adjusting the Company's asset/liability position, Management attempts to
manage interest rate risk while enhancing 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.

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, assuming an increase of 100 bp in the federal funds rate and an
increase of 72 bp in the 10 year Constant Maturity Treasury Bond yield during
the same period, estimated earnings at risk would be approximately 3.9% of the
Company's most likely net income plan for the twelve months ended March 31,
2008. Conversely, assuming a decrease of 100 bp in the federal funds rate and a
decrease of 36 bp in the 10 year Constant Maturity Treasury Bond yield during
the same period, earnings are estimated to improve 1.1% over the Company's most
likely income plan for the twelve months ended March 31, 2008. 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.

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.


Liquidity

The Company's principal sources of asset liquidity are investment securities
available for sale and principal payments from investment securities held to
maturity and consumer loans. At March 31, 2007, investment securities available
for sale totaled $602 million. At March 31, 2007, indirect automobile loans
totaled $443 million, which were experiencing stable monthly principal
payments in the range of $17 million to $20 million. In addition, at March 31,
2007, the Company had customary lines for overnight borrowings from other
financial institutions in excess of $700 million and a $35 million line of
credit, under which $22 million was outstanding at March 31, 2007. As a member
of the Federal Reserve System, the Company also has the ability to borrow from
the Federal Reserve. The Company's short-term debt rating from Fitch Ratings is
F1 with a stable outlook. Management expects the Company can access short-term
debt financing if desired. The Company's long-term debt rating from Fitch
Ratings is A with a stable outlook. Management expects the Company can access
additional long-term debt financing if desired. The Company generates
significant liquidity from its operating activities. The Company's profitability
during the first three months of 2007 and 2006 contributed to substantial
operating cash flows of $29.5 million and $33.5 million, respectively. In 2007,
operating activities provided a substantial portion of cash for $10.3 million in
shareholder dividends and $22.1 million utilized to repurchase common stock. In
2006, operating activities provided enough cash for $23.0 million of Company
stock repurchases and $10.2 million in shareholder dividends.

In the first three months of 2007, investing activities generated $52.3 million,
compared with $75.8 million in the same period of 2006. In the first three
months of 2007, sales and maturities, net of purchases, of investment securities
were $41.0 million. In the first three months of 2006, sales and maturities, net
of purchases, of investment securities were $44.0 million.

The Company anticipates maintaining its cash levels in 2007 mainly through
profitability and retained earnings. It is anticipated that loan demand will
increase moderately in 2007, although such demand will be dictated by economic
and competitive conditions. The growth of deposit balances is expected to exceed
the anticipated growth in earning assets through the end of 2007. Depending on
economic conditions, interest rate levels, and a variety of other conditions,
excess deposit growth may be used to purchase investment securities or to reduce
short-term borrowings. However, due to changes in consumer confidence, possible
terrorist attacks, the war in Iraq, and changes in the general economic
environment, loan demand and levels of customer deposits are not certain.
Shareholder dividends and share repurchases are expected to continue in 2007 but
will depend on the Board's ongoing evaluation of the advisability of such
actions.

Westamerica Bancorporation ("the Parent Company") is a separate entity from
Westamerica Bank ("the Bank") and must provide for its own liquidity. In
addition to its operating expenses, the Parent Company is responsible for
interest and principal on outstanding debt and the payment of dividends declared
for shareholders. Substantially all of the Parent Company's revenues are
obtained from service fees and dividends received from the Bank and, to a lesser
extent, other subsidiaries. Payment of such dividends to the Parent Company by
the Bank is limited under regulations for Federal Reserve member banks and
California law. The amount that can be paid in any calendar year, without prior
approval from federal and state regulatory agencies, cannot exceed the net
profits (as defined) for that year plus the net profits of the preceding two
calendar years less dividends paid. The Company believes that such restrictions
will not have an impact on the Parent Company's ability to meet its ongoing cash
obligations.


Capital Resources

The current and projected capital position of the Company and the impact of
capital plans and long-term strategies are reviewed regularly by Management. The
Company repurchases shares of its common stock in the open market pursuant to
stock repurchase plans approved by the Board with the intention of lessening the
dilutive impact of issuing new shares under stock option plans, and other
ongoing requirements. In addition, other programs have been implemented to
optimize the Company's use of equity capital and enhance shareholder value.
Pursuant to these programs, the Company repurchased 447 thousand shares in the
first quarter of 2007, 429 thousand shares in the first quarter of 2006, and 410
thousand shares in the fourth quarter of 2006.

The Company's capital position represents the level of capital available to
support continued operations and expansion. The Company's primary capital
resource is shareholders' equity, which was $419.8 million at March 31, 2007.
This amount, which is reflective of the effect of the generation of earnings,
offset by common stock repurchases, and dividends paid to shareholders,
represents a decrease of $11.3 million or 2.63% from a year ago, and a decrease
of $4.4 million or 1.04% from December 31, 2006. The Company's ratio of equity
to total assets increased to 8.84% at March 31, 2007, from 8.53% a year ago. The
shareholder's equity to total assets decreased at March 31, 2007, compared with
8.90% at December 31, 2006.

The following summarizes the Company's ratios of capital to risk-adjusted assets
for the periods indicated:





                                                                At March 31,          At         Minimum
                                                       --------------------------December 31,  Regulatory

    Tier I Capital                                             9.64%        9.41%        9.77%        4.00%
    Total Capital                                             10.96%       10.73%       11.09%        8.00%

The risk-based capital ratios rose at March 31, 2007, compared with the first
quarter of 2006, primarily due to decreases in risk-weighted assets. The
risk-based capital ratios decreased at March 31, 2007 from the previous quarter
due to a decrease in equity capital.

Capital ratios are reviewed by Management on a regular basis to ensure that
capital exceeds the prescribed regulatory minimums and is adequate to meet the
Company's anticipated future needs. All ratios as shown in the table above are
in excess of the regulatory definition of "well capitalized".


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
permitted 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, 2007. Based upon their
evaluation, the principal executive officer and principal financial officer
concluded that the Company's disclosure controls and procedures are effective.
The evaluation did not identify any change in the Company's internal control
over financial reporting that occurred during the quarter ended March 31, 2007
that has materially affected, or is reasonably likely to materially affect, the
Company's internal control over financial reporting.
