FOR IMMEDIATE RELEASE
October 17, 2006


WESTAMERICA BANCORPORATION REPORTS QUARTERLY EARNINGS
FOR THIRD QUARTER 2006

San Rafael, CA:    Westamerica Bancorporation (NASDAQ: WABC), parent company of
Westamerica Bank, today reported net income of $24.2 million for the third
quarter of 2006, compared to $24.5 million for the second quarter of 2006. Third
quarter 2006 diluted earnings per share were $0.77, unchanged from the second
quarter of 2006. Return on average common equity (ROE) for the third quarter of
2006 was 22.7 percent and return on assets (ROA) was 1.98 percent. Third quarter
2005 net income of $28.9 million, or $0.88 diluted earnings per share, includes
a gain on the sale of a facility vacated following the Redwood Empire Bancorp
acquisition and recognition of company owned life insurance proceeds which, on a
combined basis, account for $0.06 diluted earnings per share.

For the first nine months of 2006, net income totaled $74.9 million, compared to
$78.9 million for the same period in 2005. Diluted earnings per share were $2.34
for the first nine months of 2006, compared to $2.39 for the same period in
2005. Results for the first nine months of 2005 include a realized loss on sale
of securities, and gains from the sale of property, and company owned life
insurance proceeds, which, on a combined basis, reduced net income by $100
thousand.

"Results for the third quarter of 2006 include a stabilizing net interest margin
and controlled expense levels," said Chairman, President and CEO David Payne.
"Our 1.52 percent cost of funds reflects the value of our significant
noninterest bearing demand deposits and other low-cost deposits comprising 79
percent of Westamerica's deposit base. Our relatively low cost of funds
supported a 4.54 percent margin for the third quarter 2006. Cost consciousness
throughout the Company has helped reduce our noninterest expenses 3.8 percent in
the first nine months of 2006, compared to the same period last year," added
Payne.

Net interest income on a fully taxable equivalent basis was $50.2 million in the
third quarter of 2006 compared to $51.5 million and $56.0 million in the second
quarter of 2006 and the third quarter of 2005, respectively. The third quarter
of 2006 net interest margin (fully taxable equivalent) was 4.54 percent, down
from 4.58 percent and 4.76 percent in the second quarter of 2006 and the third
quarter of 2005, respectively. Rising short-term interest rates combined with
limited change in intermediate interest rates and highly competitive loan and
deposit pricing has resulted in an operating environment with declining net
interest margins.

Noninterest income for the first nine months of 2006 totaled $41.6 million,
compared to $40.1 million in the first nine months of 2005. The $1.5 million
increase is primarily due to:
      * $860 thousand higher merchant credit card income attributable to the
        acquisition of Redwood Empire Bancorp on March 1, 2005.
      * $335 thousand increase in debit card and ATM fees.
      * $480 thousand decrease in service charges on deposit accounts,
        primarily account analysis fees.
      * $600 thousand increase due to $4.9 million in securities losses and
        $4.3 million in gains from the sale of real estate and life insurance
        proceeds recognized in 2005.

Noninterest expense for the third quarter of 2006 was $25.4 million, reduced
from $26.3 million for the prior quarter and $27.3 million for the third quarter
of 2005. The efficiency ratio for the third quarter of 2006 was 39.6 percent,
compared to 40.2 percent for the prior quarter and 37.2 percent for the third
quarter of 2005.

The provision for credit losses was $75 thousand for the third quarter of 2006,
reduced from $150 thousand for the previous quarter and for the third quarter of
2005. The reduced provision for credit losses reflects management's assessment
of credit risk for the loan portfolio.

At September 30, 2006, shareholders' equity was $427 million and the Company's
total regulatory capital ratio was 11.0 percent, which exceeds the "well-
capitalized" level of 10 percent under regulatory requirements. During the third
quarter 2006, shares repurchased, net of shares issued, totaled 291 thousand
shares. At September 30, 2006, 1.9 million shares remain authorized under the
Company's stock repurchase plan.

Westamerica Bancorporation, through its wholly owned subsidiary Westamerica
Bank, operates 87 branches throughout 21 Northern and Central California
counties. At September 30, 2006, the company had total assets outstanding of
$4.8 billion.
