MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Westamerica Bancorporation (the "Company"), parent company of
Westamerica Bank, Bank of Lake County and Community Banker Services
Corporation, reported second quarter 1997 net income of $2.8
million or $.20 per share. On a year-to-date basis, the Company
reported net income of $12.2 million, or $.85 per share. Second
quarter 1997 income was impacted by one-time charges resulting
from the merger of the Company with ValliCorp Holdings, Inc. (the
"Merger"). These charges approximate $18.8 million pre-tax or $12.8
million after tax. In addition to historical information, this
discussion includes certain forward-looking statements regarding
events and trends which may affect the Company's future results.
Such statements are subject to risks and uncertainties that could
cause the Company's actual results to differ materially. Such
factors include, but are not limited to, those described in this
discussion and analysis. This report, which includes consolidated
financial statements prepared in conformity with generally accepted
accounting principles, should be read in conjunction with
Westamerica Bancorporation's annual report on Form 10-K for the
year ended December 31, 1996.


Acquisition

On April 12, 1997, the Company completed the acquisition of
ValliCorp Holdings, Inc. ("ValliCorp"), parent company of ValliWide
Bank, on a pooling-of-interests basis and, accordingly, the
Company's historical consolidated results have been restated. Under the
terms of the Agreement and Plan of Reorganization among ValliCorp,
ValliWide Bank and the Company, each share of ValliCorp Common
Stock was exchanged for .3479 shares of the Company's Common Stock.
No gain or loss for tax purposes was recognized by ValliCorp
shareholders, except with respect to cash received in lieu of
fractional shares. Based on the closing price of the Company's
Common Stock on April 11, 1997, the acquisition was valued at
approximately $290 million or $20.11 per share. On June 20, 1997,
ValliWide Bank, ValliCorp's only bank subsidiary, merged with and
into Westamerica Bank.



The following summarizes the separate results of the combined
entities for the periods shown prior to the combination:

* Fully taxable equivalent basis (FTE)


During the second quarter of 1997, the Company's net income was
$10.3 million lower than the same period in 1996. During the
quarter, the Company incurred approximately $18.8 million
of one-time costs related to the Merger, partially offset by
staff reductions and other cost controls, as operations were
consolidated and efficiencies were achieved. In addition, the
Company benefited from higher net interest income, a lower
loan loss provision, higher non-interest income and reduced
income taxes due to lower pre-tax income.

Comparing the first six months of 1997 to the prior year, 
net income decreased $10.3 million. The reasons for the reduction
in net income for this period are similar to those given above
as an explanation for the decrease in net income for the second
quarter of 1997 compared to 1996.


Analysis of Net Interest Income and Margin

The Company continually manages its interest-earning assets
and interest-bearing liabilities and the Company adapts
rapidly to changes in market rates. Second quarter net
interest income (FTE) was higher than the comparable period
in 1996 by $900,000, as the favorable effect of a higher
level of earning assets and increased balances of low-cost
deposits which resulted in lower cost of funds, were
partially offset by lower yields on earning assets. In
addition, the FTE adjustment increased from the same period
of 1996 due to an increase in the Company's average balance
of tax-exempt investment securities and loans. For the six
months ended June 30, 1997, net interest income increased
$200,000. The reasons for this change are largely similar to
those described above that explain the increase between
second quarter of 1997 and second quarter of 1996.

These variances are shown in the components of net interest
income and in the analysis of net interest margin summarized
as follows for the periods indicated:

Second quarter loan fees, excluding deferrals of $1.8 million,
included in interest income on loans, were $800,000 higher
than in the same period of 1996. On a year-to-date basis,
loan fees excluding deferrals were $800,000 higher than the
comparable period in 1996. In both cases, the increases were
due to the increase level of loan originations.

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

The net interest margin during the second quarter of 1997 was 13
basis points higher than the same period in 1996. The average yield
on earning assets in 1997 was five basis points higher than in 1996
as the Company benefited from a 32 basis point increase in
investment securities yields. This was mostly due to increased
balances of tax-free securities and the restatement of the
fully taxable equivalent adjustment on a consolidated basis
after the Merger, not previously accounted for by ValliCorp.
Furthermore, the rate paid on interest-bearing liabilities
decreased two basis points from the second quarter of 1996;
this effect was in addition to the favorable impact of higher
non-interest bearing demand deposits.

For the first six months of 1997, the net interest margin was four
basis points higher than the first six months of 1996. A four basis
point decrease in the rate paid on interest-bearing liabilities,
combined with the favorable impact of an increase in non-interest
bearing demand balances, was partially offset by a six basis point
decrease in earning-asset yields, mainly due to lower loan yields
only partially offset by higher yields on the Company's securities
portfolio.


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 amounts 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
non-performing loans. Interest income includes proceeds from
loans on non-accrual 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 thereon exempt from federal
income taxation at the current statutory tax rate.

Provision for Loan Losses

The level of the provision for loan losses during each of the
periods presented reflects the Company's continued efforts to
improve loan quality by enforcing underwriting and
administration procedures and aggressively pursuing
collection efforts with troubled debtors. Maintenance of
credit quality standards allowed the Company to reduce the
level of its provision for loan losses to $1.1 million in the
second quarter of 1997, $1.8 million lower than the same
period in 1996. On a year-to-date basis, the $4.6 million
provision for loan losses in 1997 was $1.4 million lower than
the first six months of 1996. This provision includes $2.5
million booked at ValliCorp prior to the merger, conforming
to Westamerica Bancorporation's different workout strategy
for loans and properties acquired in the merger.

For further information regarding net credit losses and the
reserve for loan losses, see the "Asset Quality" section of this
report.

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


The $490,000 increase in non-interest income during the second
quarter of 1997 compared to the second quarter of 1996, included
$130,000 higher deposit account fees, $70,000 higher financial
services commissions resulting from increased share of fees earned
by the agent managing certain investments of the Company's
customers, and $30,000 higher trust fees. In addition, the sale of
mortgage-backed securities resulted in $110,000 higher gains than
in the prior year and the gain on sale of branches was the major
contributor to the increase in the "Other" non-interest income
category. Partially offsetting these favorable variances, merchant
credit card income decreased $280,000 from the second quarter of 1996
due to a reduced level of activity, and mortgage banking fees were
$70,000 lower than the same period mainly due to lower refinancing
volume.

Comparing the first six months of 1997 to the same period of
1996, non-interest income increased $1.8 million. The largest
contributor to this variance was a gain on sale of assets at
ValliWide Bank prior to the merger with and into Westamerica Bank
and after the merger of the holding companies, included in the
"Other" non-interest income category variance of $1.6 million. In
addition, deposit account fees were $500,000 higher than prior year
principally due to higher account analysis and other transaction
account fees, and financial services commissions and trust fees
were $120,000 and $60,000, respectively, higher than the second
quarter of 1996. The sale of securities resulted in a $90,000
higher gain than in prior year. Partially offsetting these
favorable variances, merchant credit card fees and mortgage banking
income were $290,000 and $280,000, respectively, lower than prior
year due to the same reasons mentioned above for the second quarter
of 1997 compared to the same period in 1996.

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

During the second quarter of 1997, non-interest expense increased
$17.88 million from the second quarter of 1996. Major increases
from the second quarter of 1996 relate to one-time costs of
approximately $18.75 million in connection with the Merger. These
costs are mostly included in the increases shown in salaries and
incentives principally due to an estimated $7.2 million in
severance expenses, occupancy and equipment due to approximately
$6.6 million in write-offs of unused premises and furniture,
professional fees, which includes $3.9 million in investment banker
costs, and $250,000 in data processing services due to contract
termination related expenses. In addition, postage increased
$110,000 due to additional customer mailings to disclose
particulars of the ValliCorp merger and account characteristics.
Stationery and supplies expenses increased $40,000 mainly due to
inventory set-ups at the new branches joining the Company's
network. Completing the increased variances in non-interest
expense, operational losses and courier costs increased $30,000 and
$20,000, respectively, from the second quarter of 1996. Reductions
in non-interest expense from the second quarter of 1996 include
$390,000 lower marketing expense and merchant credit card and other
real estate owned related costs, $90,000 and $30,000, respectively.


Comparing the first six month of 1997 with the comparable period in
1996, non-interest expense increased $17.49 million. The reasons
listed above for the variances between the second quarter of 1997
and the second quarter of 1996, are similar to those explaining
the changes between the first six months of both years with the
addition of certain items included in the first quarter of
1997, also related to the ValliCorp merger, such as increased
professional fees and increased occupancy and furniture and
equipment costs due to higher branch restructuring costs at
ValliWide Bank prior to the merger with and into Westamerica
Bank. The decrease of $4.49 million in the Other category of
non-interest expense is mainly due to merger and integration costs
at ValliCorp during 1996 totaling $4.58 million.


Provision for Income Tax

During the second quarter of 1997, the Company recorded income tax
expense of $1.9 million compared to $6.8 million in the second
quarter of 1996. On a year-to-date basis, income tax expense was
$6.7 million for 1997 compared to $11.2 million in 1996. The
provision recorded for the first six months of 1997 represents an
effective tax rate of 35.4 percent, compared to 33.3 percent for
the first six months of 1996. The provision for income taxes for
all periods presented is directly attributable to the respective
level of earnings and the non-tax deductible expenses incurred
in connection with mergers and acquisitions.


Asset Quality

The Company closely monitors the markets in which it conducts its
lending operations. The Company continues its strategy to control
exposure to loans with high credit risk and increase diversification
of earning assets into less risky investments. Asset reviews are
performed using grading standards and criteria similar to those
employed by bank regulatory agencies. Assets receiving lesser grades
fall under the "classified assets" category, which includes all
non-performing assets and potential problem loans, and receive an
elevated level of attention to ensure collection. The following is a
summary of classified assets on the dates indicated:

  a percentage of
  classified loans                    68%           54%           81%


Classified loans at June 30, 1997, decreased $11.8 million or 14
percent to $74.1 million from June 30, 1996, principally due to
sales and pay-offs of loans with real estate collateral and
transfers to the other real estate owned category. The $11.2
million increase of classified loans from December 31, 1996 was
mainly due to increases in residential real estate loans and other
loans with real estate collateral.


Non-performing Assets

Non-performing assets include non-accrual loans, loans 90 days past
due as to principal or interest and still accruing and other real
estate owned. Loans are placed on non-accrual status when reaching
90 days or more delinquent, unless the loan is well secured and in
the process of collection. Interest previously accrued on loans
placed on non-accrual 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 non-accrual status even though the
borrowers continue to repay the loans as scheduled. Such loans are
classified as "performing non-accrual" and are included in total
non-performing assets. Performing non-accrual loans are reinstated
to accrual status when improvements in credit quality eliminate
Management's doubt as to the full collectibility of both interest


and principal and the loan is brought current. When the ability to
fully collect non-accrual 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.

The following is a summary of non-performing assets on the dates
indicated:

Performing non-accrual loans increased $7.21 million to $9.39
million at June 30, 1997 from $2.18 million at June 30, 1996 and
increased $5.10 million from $4.29 million outstanding at December
31, 1996. The majority of the increases was due to reclassifications
from non-performing into performing non-accrual loans that were not
classified as such by ValliWide Bank prior to the merger with and
into Westamerica Bank. Non-performing non-accrual loans of $11.40
million at June 30, 1997, decreased $5.81 million from June 30,
1996 and decreased $1.15 million from December 31, 1996.
These reductions were in part due to the mentioned reclassification
from non-performing into performing non-accrual loans from
ValliWide Bank's loans in addition to payoffs and write-offs of
loans with real estate collateral and commercial loans. The
$211,000 and $262,000 decreases in other real estate owned balances
from June 30, 1996 and December 31, 1996, respectively, were due


to additions from non-accrual loans with real estate collateral net
of liquidations, write-downs and sales.

The amount of gross interest income that would have been
recorded for non-accrual loans for the three and six months
ended June 30, 1997, if all such loans had been current in
accordance with their original terms, was $495,000 and
$667,000, respectively. The amount of interest income that
was recognized on non-accrual loans from cash payments made
during the three and six months ended June 30, 1997 totaled
$120,000 and $220,000, respectively, representing annualized
yields of 2.45 percent and 3.28 percent, respectively. Cash
payments received which were applied against the book balance
of non-accrual loans outstanding at June 30, 1997, totaled
$510,000.


Reserve for Loan Losses

It is the position of the Company that the level of the loan
loss reserve is adequate to provide for losses that can be
estimated based on anticipated specific and general
conditions as determined by Management. These include credit
loss experience, the amount of past due, non-performing and
classified loans, recommendations of regulatory authorities
and prevailing economic conditions. The reserve is allocated
to segments of the loan portfolio based in part on
quantitative analyses of historical credit loss experience.
Criticized and classified loan balances are analyzed using
both a linear regression model and standard allocation
percentages. The results of these analyses 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 due to their small
balances and numerous accounts, are analyzed based on the
historical rate of net losses and delinquency trends grouped
by the number of days the payments on these loans are
delinquent. While these factors are judgmental and may not be
reduced to a purely mathematical formula, Management
considers the reserve for loan losses, for the periods
presented, to be adequate as a reserve against inherent
losses. Management continues to evaluate the loan portfolio
and assess current economic conditions that will dictate
future required reserve levels.

losses and loan loss reserve for the periods indicated:

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.

The primary analytical tool used by the Company to gauge
interest rate sensitivity is a simulation model used by many
major banks and bank regulators. This model is used to
simulate, based on the current and projected portfolio mix,
the effects on net interest income of changes in market
interest rates. Under the Company's policy and practice, the
projected amount of net interest income over the ensuing
twelve months is not allowed to fluctuate more than 10
percent even under alternate assumed interest rate changes of
plus or minus 200 basis points. The results of the model
indicate that the mix of interest rate sensitive assets and
liabilities at June 30, 1997 would not result in a
fluctuation of net income exceeding 10 percent.

The Securities and Exchange Commission (SEC) has approved
rule amendments to clarify and expand existing disclosure
requirements for derivative financial instruments. The
amendments require enhanced disclosure of accounting policies
for derivative financial instruments in the footnotes to the
financial statements. In addition, the amendments expand
existing disclosure requirements to include quantitative and
qualitative information about market risk inherent in market
risk sensitive instruments. The required quantitative and
qualitative information should be disclosed outside the
financial statements and related notes thereto. The enhanced
accounting policy disclosure requirements are effective for
the quarterly period ended June 30, 1997. As the Company
believes that the derivative financial instrument disclosures
contained within the notes to the financial statements of its
1996 Form 10-K substantially conform with the accounting
policy requirements of these rule amendments, no further
interim disclosure has been provided. The rule amendments
that require expanded disclosure of quantitative and
qualitative information about market risk are effective with
the 1997 Form 10-K. At June 30, 1997 and 1996, the Company
had no derivative financial instruments outstanding.


Liquidity

The Company's principal source of asset liquidity is marketable
investment securities available for sale. At June 30, 1997,
investment securities available for sale totaled $907.8 million.
This represents an increase of $61.0 million from June 30, 1996.


The Company generates significant liquidity from its
operating activities. The Company's profitability during the
first six months of 1997 and 1996 was the main contributor
to the cash flows from operations for such periods of $28.5
million and $21.4 million, respectively.

Cash flows are provided by and used in financing activities,
primarily customer deposits, short-term borrowings from
banks, extensions of long-term debt and repurchases of the
Company's Common Stock. During the first six months of 1997,
$138.0 million was used by financing activities, including a
$111.3 million decrease in deposits, a $16.0 million decrease
in short-term borrowings, a $15.1 million outflow used for
purchasing the Company's common stock, dividends paid in the
amount of $5.4 million and repayments of long-term debt for
$1.4 million. These uses of cash were partially offset by
$11.0 million provided by the issuance of new shares of
common stock, principally for stock option exercises.
This compares to the first six months of 1996 when $132.1 million
was used in financing activities, as a $175.4 million decrease in
deposits combined with other cash flow uses including retirement of
stock and dividends to shareholders of $13.0 million and $5.8
million, respectively, and repayments of long-term debt of
$4.4 million, were partially offset by a $40.6 million
increase in short-term borrowed funds, the issuance of $22.5
million of the Company's Senior Notes and a $3.5 million
increase in common stock from stock option exercises.

The Company uses cash flows from operating and financing activities
primarily to invest in securities and loans. During the first six
months of 1997, net repayments of loans were $5.7 million compared
to $9.8 million during the same period in 1996. The Company
continued to grow its investment securities portfolio in 1997,
reflected in the $22.0 million increase in investment securities,
net of maturities and sales, for the first six months of 1997,
compared to a decrease of $83.6 million during the same period of
1996. Costs related to the new facility to consolidate the
Company's operations and back office functions to Fairfield,
California, were the main reason for the $13.1 million in
purchases of property, plant and equipment, during the first six
months of 1996.

The Company anticipates increasing its cash level from
operations through the end of 1997 due to increased
profitability and retained earnings. For the same period, it
is anticipated that the investment securities portfolio and
demand for loans will moderately increase. The growth in
deposit balances is expected to follow the anticipated growth
in loan and investment balances through the end of 1997.


Capital Resources

The current and projected capital position of the Company and the
impact of capital plans and long-term strategies is reviewed
regularly by Management.

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 $387.0 million at June 30, 1997, representing an increase of
$31.5 million or 9 percent from June 30, 1996 and an increase of
$7.7 million, or 2 percent, from December 31, 1996. As a result of
the Company's profitability and the retention of earnings, the
ratio of equity to total assets increased to 10.3 percent at June
30, 1997, from 9.5 percent a year ago and 9.8 percent as of
December 31, 1996. The ratio of Tier I capital to risk-adjusted
assets was 12.68 percent at June 30, 1997, compared to 12.95
percent at June 30, 1996 and 12.96 percent at December 31, 1996.
Total capital to risk-adjusted assets was 14.64 percent at June 30,
1997 compared to 14.96 percent at June 30, 1996 and 14.95 percent
at December 31, 1996.

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


                                         June 30,       December 31,
                                  --------------------  -------------
                                    1997          1996          1996
                                  ------        ------        ------
                                                      
Tier I Capital                     12.68%        12.95%        12.96%
Total Capital                      14.64%        14.96%        14.95%
Leverage ratio                      9.67%         9.26%         9.27%

The risk-based capital ratios decreased at June 30, 1997 compared to
June 30, 1996 as the increase in risk weighted assets outpaced the
growth in total equity, due in part to the increase in loan
balances and other assets. Capital ratios are reviewed on a regular
basis to ensure that capital exceeds the prescribed regulatory
minimums and is adequate to meet the Company's future needs. All
ratios are in excess of the regulatory definition of "well
capitalized".

Since the beginning of 1994, the Board of Directors of the
Company has authorized the repurchase of 914,050 shares of
common stock from time to time, subject to appropriate
regulatory and other accounting requirements. These purchases
are made periodically in the open market and lessen the
dilutive impact of issuing new shares to meet stock
performance, option plans, acquisitions and other
requirements. Pursuant to this program, 674,050 shares had
been purchased through December 31, 1996, 12,500 were
purchased during the first quarter of 1997 and 168,200 were
purchased during the second quarter of 1997.


Interim Periods

In February, 1997, the Financial Accounting Standards Board (FASB)
issued Statement of Financial Accounting Standards No. 128, 
"Earnings per Share" ("SFAS 128"). SFAS 128 establishes standards
for computing and presenting earnings per share ("EPS") and applies
to entities with publicly held common stock or potential common
stock. SFAS 128 simplifies the standards for computing earnings per
share previously found in APB Opinion No. 15, "Earnings per Share",
and replaces the presentation of primary EPS with a presentation of
basic EPS. It also requires dual presentation of basic and diluted
EPS on the face of the income statement and requires a
reconciliation of the numerator and denominator of the basic EPS
computation to the numerator and denominator of the diluted EPS
computation. SFAS 128 is effective for financial statements issued
for periods ending after December 15, 1997, including interim
periods; earlier application is not permitted. This statement
requires restatement of all prior-period EPS data presented.

The pro forma EPS amounts computed using this statement for the
three and six-month periods ended June 30, 1997 and 1996 are as
follows:

In June 1997, the FASB issued Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). SFAS 130 establishes standards for
reporting and displaying comprehensive income and its
components in the financial statements. It requires that a
company classify items of other comprehensive income, as
defined by accounting standards, by their nature (e.g.,
unrealized gains or losses on securities) in a financial
statement, but does not require a specific format for that
statement. The Company is in the process of determining its
preferred format. The accumulated balance of other
comprehensive income is to be displayed separately from
retained earnings and additional paid-in capital in the
equity section of the balance sheet. SFAS 130 is effective
with the year-end 1998 financial statements; however, a total
for comprehensive income is required in the financial
statements of interim periods beginning in 1998.
Reclassification of financial statements for earlier periods
provided for comparative purposes is required.


In June 1997, the FASB issued Statement of Financial
Accounting Standards No. 131, "Disclosures about Segments of
an Enterprise and Related Information" ("SFAS 131"). SFAS 131
requires that a public business enterprise report financial
and descriptive information about its reportable operating
segments on the basis that is used internally for evaluating
segment performance and deciding how to allocate resources to
segments. SFAS 131 is effective with the year-end 1998
financial statements. No comparative information will be
required for interim periods in the initial year of
application.
