PART I

ITEM I: BUSINESS

WESTAMERICA BANCORPORATION (the "Company") is a multi bank holding company
registered under the Bank Holding Company Act of 1956 ("BHC"), as amended.
It was incorporated under the laws of the State of California as
"Independent Bankshares Corporation" on February 11, 1972. Its principal
executive offices are located at 1108 Fifth Avenue, San Rafael, California
94901, and its telephone number is (415) 257-8000.

The Company was originally formed pursuant to a plan of reorganization
among three previously unaffiliated banks: Bank of Marin, Bank of Sonoma
County and First National Bank of Mendocino County (formerly First National
Bank of Cloverdale). The reorganization was consummated on December 31,
1972, and, on January 1, 1973, the Company began operations as a bank
holding company. Subsequently, the Company acquired Bank of Lake County
(a California chartered bank) in 1974, Gold Country Bank in 1979 and Vaca
Valley Bank in 1981, in each case by the exchange of the Company's Common
Stock for the outstanding shares of the acquired banks.

In mid-1983, the Company consolidated the six subsidiary banks into a
single subsidiary bank. The consolidation was accomplished by the merger
of the five state chartered banks (Bank of Marin, Bank of Sonoma County,
Bank of Lake County, Gold Country Bank and Vaca Valley Bank) into First
National Bank of Mendocino County which subsequently changed its name to
Westamerica Bank ("WAB"), which was a national banking association
organized and existing under the laws of the United States. The Company
also owns all the capital stock of Learnex Corp., a now inactive sales
training company.

On February 28, 1992 the Company acquired John Muir National Bank through a
merger of such bank into WAB in exchange for the issuance of the Company's
Common Stock for all of the outstanding shares of John Muir National Bank.
This business transaction was accounted for as a pooling-of-interests
basis.

On April 15, 1993, the Company issued approximately 2,122,740 shares of its
common stock in exchange for all of the outstanding common stock of Napa
Valley Bancorp, a bank holding company, whose subsidiaries included Napa
Valley Bank ("NVB"), a California-based, state-chartered banking
association, and Subsidiary, 88 percent interest in Bank of Lake County
("BLC"), a national banking association, 50 percent interest in Sonoma
Valley Bank, a state banking association, Suisun Valley Bank, also a state
chartered bank, and Napa Valley Bancorp Services Corporation ("NVBSC"),
established to provide data processing and other services to Napa Valley
Bancorp's subsidiaries. This business transaction (the "Merger") was
accounted for as a pooling-of-interests combination and accordingly, the
consolidated financial statements and financial data for periods prior to
the combination have been restated to include the accounts and results of
operations of Napa Valley Bancorp. Certain reclassifications have been
made to Napa Valley Bancorp to conform to the Westamerica Bancorporation's
presentation.

Shortly after the Merger, Suisun Valley Bank was merged into Westamerica
Bank and the name of the NVBSC was changed to Community Banker Services
Corporation. Subsequent to the Merger, the Company sold its 50 percent
interest in Sonoma Valley Bank and started proceedings to purchase the Bank
of Lake County's outstanding minority interest. In addition, after the
Merger, Westamerica Bank and Bank of Lake County changed their charters
from national banking associations to California state-chartered banks.

Napa Valley Bank owns all of the outstanding shares of Napa Valley
Development, a California corporation which was formed to own, develop and
market real estate.

In June 1993, the Company accepted from its wholly owned subsidiary
Westamerica Bank, a dividend in the form of all of the outstanding shares
of capital stock of that bank's subsidiary, Weststar Mortgage Corporation,
a California corporation established to conduct mortgage banking
activities. Immediately after the receipt of this dividend, the Company
contributed all of the capital stock of Weststar Mortgage Corporation to
its subsidiary, Community Banker Services Corporation.

At December 31, 1993, the Company had consolidated assets of approximately
$2.00 billion, deposits of approximately $1.73 billion and shareholders'
equity of approximately $152.4 million.

Westamerica Bank, Napa Valley Bank and Bank of Lake County ("the Banks")
are engaged in the banking business through 52 offices in eleven counties
in Northern California, including twelve offices in Marin County, nine in
Sonoma County, eight in Solano County, seven in Napa County, five in
Contra Costa County, four in Lake County, two in Mendocino County, two in
Nevada County, one in Sacramento County, one in San Francisco County and
one in Placer County. All offices are constructed and equipped to meet
prescribed security requirements.

The Banks own fifteen banking office locations and four administrative
buildings, including the Company's and WAB's headquarters. Thirty-seven
banking offices and two support facilities are leased. Substantially all
of the leases contain multiple five-year renewal options and provisions for
rental increase, principally for changes in the cost of living index,
property taxes and maintenance.

SERVICE AREA

The Banks serve the following ten major market areas:

MARIN COUNTY. Marin County is one of the most affluent counties in
California and has a population of approximately 241,300. San Rafael and
Novato are the largest communities in the county, with populations of
approximately 52,100 and 48,900, respectively, in close proximity to San
Francisco. The area served by WAB is a relatively densely populated area
whose economic make-up is primarily residential, commercial and light
industrial.

SONOMA-MENDOCINO COUNTIES. Of the eight San Francisco Bay Area counties,
Sonoma County is the largest geographically. The population of the county
is approximately 416,300. The City of Santa Rosa is the largest population
center in Sonoma County with an estimated population of 123,800 people.
Light industry, agriculture and food processing are the primary industries
in Sonoma County, with tourism and recreational activities growing
steadily. WAB also has two branch locations in southern Mendocino County,
population 83,600, where the major business of the county is agriculture.

NEVADA COUNTY. WAB is currently serving most of Nevada County, the area
generally known as the "Gold Country." The population of the entire county
is approximately 85,500. Tourism, agriculture and wood products
manufacturing are the major industries.

SOLANO COUNTY. WAB serves all of Solano County, with an estimated
population of 369,500. Vallejo is the largest city in the county, with a
population of approximately 115,900. While light industry and the service
sector is growing steadily, the federal government is the largest employer
in the county.

SACRAMENTO COUNTY. In 1982, WAB established an office in the city of
Sacramento, the state capital of California. The county has a population
of approximately 1,121,200. Major industries include agriculture,
government, manufacturing and wholesale and retail trade. Sacramento is
also a major transportation center for the State.

CONTRA COSTA COUNTY. During 1984, WAB opened an office in the city of
Walnut Creek, to serve Contra Costa County's growing commercial and
industrial construction industry. In 1992, the Company acquired John Muir
National Bank whose four banking offices in Martinez, Pittsburg and Antioch
were merged into the WAB. The population of Contra Costa County is
approximately 855,100.

SAN FRANCISCO COUNTY. In 1987, WAB opened an office in the financial
center of the City of San Francisco, with a focus on commercial lending and
deposit relationships in that city.

PLACER COUNTY. In September 1991, WAB opened a new branch in Roseville,
which is approximately 15 miles east of the Sacramento office and serves
the growing area of the Sierra Nevada foothills.

LAKE COUNTY. Bank of Lake County, ("the Lake County's Bank"), has office
locations in Lake County, with an estimated population of approximately
55,600. Agriculture is the primary industry followed closely by recreation
and tourism.

NAPA COUNTY. Napa Valley Bank has office locations in Napa County. The
population of the county is approximately 116,900, with agriculture being
its major source of business followed by tourism.

Neither the Company nor its subsidiaries have any foreign or international
activities or operations.

All population figures contained in the previous discussion are 1993
estimates as prepared by the California Department of Finance and are
exclusive of unincorporated areas.

COMPETITION

The Banks compete with other commercial banks, savings & loan
associations, credit unions, brokerage firms, money market mutual funds,
finance and insurance companies and mortgage banking firms.

According to information obtained by the Company through an independent
market research firm, WAB was the third largest financial institution in
terms of deposits in Marin County at June 30, 1993, at which date it had
approximately 14 percent of total deposits held in banks and savings & loan
associations in that county. Also, according to such information, WAB
ranked third in Sonoma County at June 30, 1993, with approximately 8
percent of deposits; WAB was fourth in Contra Costa as of the same date,
with over 4 percent in deposits held in financial institutions in the
county and WAB was third in deposits in Solano County, with approximately
12 percent of deposits at June 30, 1993. The share of the market for
deposits and loans held by WAB in Mendocino, Placer, San Francisco and
Sacramento Counties is not significant.

According to the same source of information NVB was the largest financial
institution in terms of deposits in the Napa Valley service area as of June
30, 1993, with over 20 percent market share.

The same source of data reports that as of June 30, 1993, BLC ranked second
in market share in terms of deposits in the Lake County service area, with
17 percent of the total.

All Banks provide checking and savings deposit services as well as
commercial, real estate and personal loans. In addition, most of the
branches offer safe deposit facilities, automated teller units, collection
services and other investment services.

The Banks believe that personal, prompt, professional service and community
identity are important in the banking business. To this end, each Bank
subsidiary has actively sought to retain its community identity and has
emphasized personalized services through "big bank resources with small
bank resourcefulness."

Competitive conditions continue to intensify as legislative enactments
dissolve historical barriers to participation in financial markets.
Competition is expected to further increase in the state of California, as
a result of legislation enacted in 1986 and 1989. In part, the legislation
enabled bank holding companies based outside California to own and operate
banks or bank holding companies in California on a reciprocal basis as of
January 1, 1991.

Legislative changes, as well as technological and economic factors, can be
expected to have an ongoing impact on competitive conditions within the
financial services industry. As an active participant in the financial
markets, the Company continually adapts to these changing competitive
conditions.

EMPLOYEES

At December 31, 1993, the Company employed 1,132 people (816 full-time
equivalent staff). Employee relations are believed to be good.

SUPERVISION AND REGULATION

Regulation of Westamerica Bancorporation

The Company is a bank holding company registered under the BHC Act. As
such, it is subject to the supervision of the Federal Reserve Board ("FRB")
and is required to file with that entity an annual report and such other
additional information as the FRB may require pursuant to the BHC Act. The
FRB may also make examinations of the Company and its respective
subsidiaries.

Under the BHC Act, bank holding companies are generally required to obtain
the prior approval of the FRB before they may (i) acquire control of or
merge with another bank holding company; (ii) acquire direct ownership or
control of 5 percent or more of the voting shares of a bank; or (iii)
otherwise acquire control of another bank. Moreover, the BHC Act generally
prohibits the Company or any of its subsidiaries from acquiring the voting
shares of, interest in or assets of, any bank located outside of California
unless the laws of such state expressly authorize such an acquisition.

Under the BHC Act, the Company is prohibited from engaging in any business
other than managing or controlling banks, or furnishing services to its
subsidiaries, unless the business proposed to undertake has been deemed
by the FRB to be so closely related to banking or managing or controlling
banks as to be a proper incident thereto. With certain exceptions, the
Company is prohibited from acquiring direct or indirect ownership or
control of more than 5 percent of the voting securities or assets of any
company unless that company engages in activities which are permissible for
bank holding companies and the FRB is given notice thereof or approves the
acquisition in advance.

Holding companies and any of their subsidiary banks are prohibited from
engaging in certain tie-in arrangements in connection with the extension of
credit. For example, a subsidiary bank generally may not extend credit on
the condition that the customer obtain some additional service from such
bank or its holding company, or refrain from obtaining such service from a
competitor.

The Company is also a bank holding company within the meaning of Section
3700 of the California Financial Code. As such, the Company and its
subsidiaries are subject to examination by, and may be required to file
reports with, the Superintendent of California State Banking Department.
Regulations have not yet been proposed or adopted, nor have steps otherwise
been taken, to implement the Superintendent's powers under this statute.

REGULATION OF BANK SUBSIDIARIES

The deposits of the Banks are insured by the FDIC in an amount up to
$100,000 per depositor and is therefore subject to applicable provisions of
the Federal Deposit Insurance Act and the regulations thereunder, including
the obligation to pay semiannual assessments for such insurance.

Transactions with affiliates of a bank must be on substantially the same
terms as would be available for nonaffiliates. This restriction applies
to (i) a bank's sale of assets, payment of money or furnishing of services
to an affiliate; (ii) transactions with the bank in which an affiliate acts
as agent or broker; and (iii) transactions with the bank and a third party
in which an affiliate is also a participant or has a financial interest.
The FDIC has issued an advance notice of proposed rulemaking which would
prohibit insured banks from paying excessive fees for services provided by
their parent holding companies. The FDIC has also proposed rules which
would authorize it to rescind contracts between depository institutions and
any person in connection with providing goods, products or services if the
performance of such contract would adversely affect the safety or soundness
of the institution.

The Financial Institutions Reform, Recovery and Enforcement Act of 1989
contains a "cross-guarantee" provision which could result in any insured
depository institution owned by a holding company (i.e., any bank
subsidiary) being assessed for losses incurred by the FDIC in connection
with assistance provided to, or the failure of, any other depository
institution owned by such holding company.

As a consequence of the extensive regulation of commercial banking
activities in the United States, the business of the Company and its
subsidiary banks is particularly susceptible to being affected by enactment
of federal and state legislation which may have the effect of increasing or
decreasing the cost of doing business, modifying permissible activities, or
enhancing the competitive position of other financial institutions. In
response to various business failures in the savings and loan industry and
more recently in the banking industry, in December 1991, Congress enacted
and the President signed significant banking legislation entitled the
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA").
FDICIA substantially revises the bank regulatory and funding provisions of
the Federal Deposit Insurance Act and makes revisions to several other
federal banking statutes.

Among other things, FDICIA provides increased funding for the Bank
Insurance Fund (the "BIF") of the FDIC, primarily by increasing the
authority of the FDIC to borrow from the United States Treasury Department.
It also provides for expanded regulation of depository institutions and
their affiliates. A significant portion of the borrowings would be repaid
by insurance premiums assessed on BIF members, including the Banks and
their subsidiaries. In addition, FDICIA generally mandates that the FDIC
achieve a ratio of reserves to insured deposits of 1.25 percent within the
next 15 years, also to be financed by insurance premiums. The result of
these provisions could be a significant increase in the assessment rate on
deposits of BIF members. FDICIA also provides authority for special
assessments against insured deposits. No assurance can be given at this
time as to what the future level of premiums will be.

As required by FDICIA, the FDIC adopted a transitional risk-based
assessment system for deposit insurance premiums which became effective
January 1, 1993. Under this system, depository institutions are charged
anywhere from 23 cents to 31 cents for every $100 in insured domestic
deposits, based on such institutions' capital levels and supervisory
ratings. The FDIC is scheduled to review the system every six months after
the effective date, with a permanent risk-based assessment system scheduled
to take effect on January 1, 1994. FDICIA prohibits assessment rates from
falling below the current annual assessment rate of 23 cents per $100 of
eligible deposits if the FDIC has outstanding borrowings from the United
States Treasury Department or the 1.25 percent designated reserve ratio has
not been met. The ultimate effect of this risk-based assessment system
cannot be determined until the permanent system becomes effective in 1994.

FDICIA also restricts the acceptance of brokered deposits by insured
depository institutions and contains a number of consumer banking
provisions, including disclosure requirements and substantive contractual
limitations with respect to deposit accounts.

FDICIA contains numerous other provisions, including new reporting,
examination and auditing requirements, termination of the "too big to fail"
doctrine except in special cases, limitations on the FDIC's payment of
deposits at foreign branches, and revised regulatory standards for, among
other things, real estate lending and capital adequacy.

Implementation of the various provisions of FDICIA are subject to the
adoption of regulations by the various banking agencies or to certain
phase-in periods. The effect of FDICIA on the Company and its subsidiary
bank cannot be determined until implementing regulations are adopted by the
agencies.

REGULATIONS APPLICABLE TO BANK SUBSIDIARIES The Company's subsidiary banks
are state-chartered banks and subject to regulation, supervision and
regular examinations by the State of California Banking Department as well
as the FDIC. The regulations of these agencies and the FRB affect most
aspects of the banking business and prescribe permissible types of loans
and investments, requirements for branch offices, the permissible scope of
activities and various other requirements. As WAB is also a member of the
Federal Reserve System, it is subject to certain other regulations of the
FRB dealing primarily with check clearing activities, establishment of
banking reserves, truth-in-lending, truth-in-savings and equal credit
opportunity.

CAPITAL REQUIREMENTS

RISK-BASED CAPITAL RATIO. The agencies which regulate financial
institutions have adopted risk-based capital adequacy standards applicable
to financial institutions. These guidelines provide a measure of capital
adequacy and are intended to reflect the degree of risk associated with
both on and off balance sheet items, including residential loans sold with
recourse, legally binding loan commitments and standby letters of credit.
Under these regulations, financial institutions are required to maintain
capital to support activities which in the past did not require capital.
Failure to meet the minimum capital requirements established by the
regulators will result in an institution being classified as
"undercapitalized", "significantly undercapitalized", or "critically
undercapitalized".

A financial institution's risk-based capital ratio is calculated by
dividing its qualifying capital by its risk-weighted assets. Financial
institutions generally are expected to meet a minimum ratio of qualifying
total capital to risk-weighted assets of 8 percent, of which at least 4
percent of qualifying total capital must be in the form of core capital
(Tier 1), i.e., common stock, noncumulative perpetual preferred stock,
minority interests, retained earnings in equity capital accounts of
consolidated subsidiaries and allowed mortgage servicing rights less all
intangible assets other than allowed mortgage servicing rights.
Supplementary capital (Tier 2) consists of the allowance for loan losses up
to 1.25 percent of risk-weighted assets, cumulative preferred stock, term
preferred stock, hybrid capital instruments and term subordinated debt.
The maximum amount of Tier 2 capital which may be recognized for risk-based
capital purposes is limited to 100 percent of Tier 1 capital (after any
deductions for disallowed intangibles). Certain other limitations and
restrictions apply as well.

The risk-based capital ratio analysis establishes minimum supervisory
guidelines and standards. The guidelines do not currently evaluate all
factors affecting an organization's financial condition. Factors which are
not evaluated include (i) overall interest rate exposure; (ii) liquidity,
funding and market risks; (iii) quality and level of earnings; (iv)
investment or loan portfolio concentrations; (v) quality of loans and
investments; (vi) the effectiveness of loan and investment policies; and
(vii) management's overall ability to monitor and control other financial
and operating risks. FDICIA also requires the guidelines to reflect the
actual performance and expected risk of loss of multifamily mortgages.
These provisions will affect the capital positions and capital standing of
all institutions and may result in the need for increased capital.
However, the ultimate effect of FDICIA risk-based capital provisions cannot
be determined until final regulations are adopted. Until such time,
however, the capital adequacy assessment of federal bank regulators will
continue to include analysis of the foregoing elements and, in particular,
the level and severity of problem and classified assets.

MINIMUM LEVERAGE RATIO. The FDIC and the FRB have also adopted a 4 percent
minimum leverage ratio which is intended to supplement risk-based capital
requirements and to ensure that all financial institutions, even those that
invest predominantly in low risk assets, continue to maintain a minimum
level of Tier 1 capital. A financial institution's minimum leverage ratio
is determined by dividing its Tier 1 capital by its quarterly average total
assets, less intangibles not includable in Tier 1 capital.

Under the guidelines, a minimum leverage ratio of 4 percent is required for
institutions which have been determined to be in the highest of five
categories used by regulators to rate financial institutions. All other
organizations are required to maintain leverage ratios of at least 100 to
200 basis points above the 4 percent minimum. It is improbable, however,
that an institution with a 4 percent leverage ratio would be rated in the
highest category since a strong capital position is also a requirement for
the highest rating. Therefore, the "minimum" leverage ratio is, for all
practical purposes, significantly above 4 percent.

The leverage ratio establishes a limit on the ability of banking
organizations, including the Company, to increase assets and liabilities
without increasing capital proportionately. The Company's Management
believes that conformance with the leverage ratio will not have an adverse
effect on the operations of the Company or require it to raise additional
capital in the foreseeable future.

NEW CAPITAL STANDARDS. FDICIA requires the federal banking regulators to
take "prompt corrective action" with respect to banks that do not meet
minimum capital requirements. In response to this requirement, the FDIC
and, the FRB participated in the adoption of final rules based upon
FDICIA's five capital tiers. These rules provide that an institution is
"well capitalized" if its risk-based capital ratio is 10 percent or
greater; its Tier 1 risk-based capital ratio is 6 percent or greater; its
leverage ratio is 5 percent or greater; and the institution is not subject
to a capital directive. A bank is "adequately capitalized" if its
risk-based capital ratio is 8 percent or greater; its Tier 1 risk-based
capital ratio is 4 percent or greater; and its leverage ratio is 4 percent
or greater (3 percent or greater for one rated institutions). An
institution is considered "undercapitalized" if its risk-based capital
ratio is less than 8 percent; its Tier 1 risk-based capital ratio is less
than 4 percent; or its leverage ratio is 4 percent or less (less than 3
percent for one rated institutions). An institution is "significantly
undercapitalized" if its risk-based capital ratio is less than 6 percent;
its Tier 1 risk-based capital ratio is less than 3 percent; or its leverage
ratio is less than 3 percent. A bank is deemed to be "critically
undercapitalized" if its ratio of tangible equity (Tier 1 capital) to total
assets is equal to or less than 2 percent. An institution may be deemed to
be in a capitalization category that is lower than is indicated by its
actual capital position if it engages in unsafe or unsound banking
practices.

No sanctions apply to institutions which are well capitalized. Adequately
capitalized institutions are prohibited from accepting brokered deposits
without the consent of the primary regulator. Undercapitalized
institutions are required to submit a capital restoration plan for
improving capital. In order to be accepted, such plan must include a
financial guaranty from the institution's holding company that the
institution will return to capital compliance. If such a guarantee were
deemed to be a commitment to maintain capital under the Federal Bankruptcy
Code, a claim for a subsequent breach of the obligations under such
guarantee in a bankruptcy proceeding involving the holding company would be
entitled to a priority over third party general unsecured creditors of the
holding company. Undercapitalized institutions are prohibited from making
capital distributions or paying management fees to controlling persons; may
be subject to limitations pertaining to growth; and are restricted from
acquisitions, branching and entering into new lines of business. Finally,
the institution's regulatory agency has discretion to impose certain of the
restrictions generally applicable to significantly undercapitalized
institutions.

In the event an institution is deemed to be significantly undercapitalized,
it may be required to: sell stock; merge or be acquired; restrict
transactions with affiliates including restrictions on payment of
dividends; restrict interest rates paid; divest a subsidiary; or dismiss
specified directors or officers. If the institution is a bank holding
company, it may be prohibited from making any capital distributions without
prior approval of the FRB and may be required to divest a subsidiary. A
critically undercapitalized institution is generally prohibited from making
payments on subordinated debt and may not, without the approval of the
FDIC, enter into a material transaction other than in the ordinary course
of business; engage in any covered transaction; or pay excessive
compensation or bonuses. Critically undercapitalized institutions are
subject to appointment of a receiver or conservator.

As of December 31, 1993, the Company was in compliance with applicable
capital and risk-based capital ratio requirements.

The Company has paid cash dividends on its common stock in every quarter

since commencing operations on January 1, 1973, and it is currently the
intention of the Board of Directors of the Company to continue payment of
cash dividends on a quarterly basis. There is no assurance, however, that
any dividends will be paid since they are dependent upon the earnings,
financial condition and capital requirements of the Company and its
subsidiaries. Furthermore, the Company's ability to pay future dividends is
subject to contractual restrictions under the terms of three note
agreements, as discussed in Note 6 to the Consolidated Financial
Statements. Under the most restrictive of these contractual provisions,
$17.1 million of retained earnings was available for the payment of
dividends at December 31, 1993. Limitations of the Company's ability to
pay dividends is discussed in Note 14 to the Consolidated Financial
Statements on page 58 of this report.

Additional information (required by Item 5) regarding the amount of cash
dividends declared on common stock for the two most recent fiscal years is
discussed in Note 16 to the Consolidated Financial Statements on page 62
of this report.

ITEM 7: MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The following discussion addresses information pertaining to the financial
condition and results of operations of Westamerica Bancorporation (the
Company) that may not be otherwise apparent from a review of the
consolidated financial statements and related footnotes. It should be read
in conjunction with those statements and notes found on pages 36 through
63, as well as with the other information presented throughout the report.

All financial information has been restated on an historical basis to
reflect the April 15, 1993 merger with Napa Valley Bancorp (the Merger) on
a pooling-of-interests basis.

The Company earned $9.5 million in 1993, representing a 38 percent decrease
from 1992 record earnings of $15.2 million and a 21 percent reduction from
1991 earnings of $12.0 million. The 1993 results include a second quarter
loss of $4.1 million, mostly due to $10.5 million after-tax merger-related
charges that were taken in the form of asset write-downs, additions to the
loan loss provision and other related charges. The asset write-downs and
the additional loan loss provision reflect the Company's plan of asset
resolution.

(Percent of average earning assets) 1993 1992 1991
- ------------------------------------------------------------------
Net interest income* 5.48% 5.50% 5.21%
Provision for loan losses (.53) (.39) (.59)
Non-interest income 1.34 1.33 1.36

Net income .53% .85% .68%
===================================================================
Net income as a percentage of
average total assets .48% .77% .62%
* Fully taxable equivalent (FTE)

On a per share basis, 1993 net income was $1.17, compared to $1.92 and
$1.52 in 1992 and 1991, respectively. During 1993, the Company continued to
benefit from reductions in cost of funds, increases in service fees and
other non-interest income, and expense controls. However, merger-related
costs more than offset these benefits. Earnings in 1992 improved over 1991
principally due to higher net interest margin, lower provisions for loan
losses and control of non-interest expense.

The Company's return on average total assets was .48 percent in 1993,
compared to .77 percent and .62 percent in 1992 and 1991, respectively.
Return on average equity in 1993 was 6.51 percent, compared to 11.16
percent and 9.52 percent, respectively, in the two previous years.

NET INTEREST INCOME

Although interest rates continued to decline during most of 1993, the
continuing downward repricing of interest-bearing liabilities and a more
favorable composition of deposits, represented by increasing volumes of
lower costing demand and savings account balances and declining volumes of
higher costing time deposits, prevented declining earning-asset yields from
significantly eroding the Company's net interest margin.

Components of Net Interest Income

(In millions) 1993 1992 1991
- -------------------------------------------------------------------
Interest income $ 137.0 $ 154.8 $ 176.6
Interest expense (42.3) (58.9) (87.4)
FTE adjustment 2.8 2.7 2.7
- -------------------------------------------------------------------
Net interest income (FTE) $ 97.5 $ 98.6 $ 91.9
- -------------------------------------------------------------------
Average interest
earning assets $1,779.3 $1,793.8 $1,762.4
Net interest margin (FTE) 5.48% 5.50% 5.21%

Net interest income (FTE) in 1993 decreased $1.1 million from 1992 to $97.5
million. Interest income decreased $17.8 million from 1992, due to a $14.5
million reduction in the average balance of interest earning assets and a
93 basis point decline in yields. This was partially offset by a $16.6
million decrease in interest expense, the combination of a $41.3 million
decrease in the average balance of interest-bearing liabilities and a 101
basis point decline in rates paid, in part due to a more favorable
composition of deposits.

DISTRIBUTION OF AVERAGE ASSETS, LIABILITIES AND SHAREHOLDERS' EQUITY

The following tables present, for the periods indicated, information
regarding the consolidated average assets, liabilities and shareholders'
equity, the amounts of interest income from average interest earning assets
and the resulting yields, and the amount of interest expense paid on
interest-bearing liabilities, expressed in thousand of dollars and rates.
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. Amortized loan fees, which are included in interest and
fee income on loans, were $1.5 million lower in 1993 than in 1992 and
$2.6 million higher in 1992 than in 1991.

PROVISION FOR LOAN LOSSES

The provision for loan losses was $9.5 million in 1993, including a $3.1
million merger-related provision in the second quarter, reflecting a
different workout strategy for loans and properties acquired in the Merger,
compared to $7.0 million in 1992 and $10.4 million in 1991. The level of
the provision reflects the Company's continuing efforts to improve loan
quality by enforcing strict underwriting and administration procedures and
aggressively pursuing collection efforts with troubled debtors. For further
information regarding net credit losses and the reserve for loan losses,
see the Non-Performing Assets section of this report.


INVESTMENT PORTFOLIO

The Company maintains a securities portfolio consisting of U.S.Treasury,
U.S. Government Agencies and Corporations, State and political subdivisions,
asset-backed and other securities. Investment securities are held in
safekeeping by an independent custodian. In May 1993, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" ("SFAS
No.115"). The statement addresses the accounting and reporting for
investments in equity securities that have a readily determinable fair
value and for all investments in debt securities. The statement requires
that all securities be classified, at acquisition, into one of three
categories: held-to-maturity, available-for-sale, and trading. SFAS No. 115
is effective for fiscal years beginning after December 15, 1993; however,
early implementation is permitted. The Company elected to implement SFAS
No. 115 effective as of December 31, 1993.

The classification of all securities is determined at the time of
acquisition. In classifying securities as being held-to-maturity,
available-for-sale or trading, the Banks consider their collateral needs,
asset/liability management strategies, liquidity needs, interest rate
sensitivity and other factors that will determine the intent and ability to
hold the securities to maturity.

The objective of the investment securities held-to-maturity is to
strengthen the portfolio yield, and to provide collateral to pledge for
federal, state and local government deposits and other borrowing
facilities. The investments held-to-maturity had an average term to
maturity of 47 months at December 31, 1993 and, as of the same date, those
investments included $547.2 million in fixed rate and $9.9 million in
adjustable rate securities.

Investment securities available-for-sale are typically used to supplement
the Banks' liquidity portfolio with the objective of increasing the
portfolio yield. Unrealized net gains and losses on these securities are
recorded as an adjustment to equity net of taxes, and are not reflected in
the current earnings of the Company. If the security is sold, any gain or
loss is recorded as a charge to earnings and the equity adjustment is
reversed. At December 31, 1993, the Banks held $168.8 million classified as
investments available-for-sale. At December 31, 1993, $2.5 million, net of
taxes was recognized as the unrealized net gain related to these
securities.

The amount of trading securitiess at December 31, 1993, was not material.

For more information on investment securities, see Notes 1 and 2 to the
Consolidated Financial Statements on pages 43 to 47 of this report.

The following table is a summary of the relative maturities (in thousands
of dollars) and yields of the Company's investment securities as of
December 31, 1993. Weighted average yields have been computed by dividing
annual interest income, adjusted for amortization of premium and accretion
of discount, by book value of the related securities. Yields on state and
political subdivision securities have been calculated on a fully taxable
equivalent basis using the federal tax rate of 34 percent.

Commitments and Lines of Credit


It is not the policy of the Company to issue formal commitments on lines of
credit except to a limited number of well established and financially
responsible local commercial enterprises. Such commitments can be either
secured or unsecured and are typically in the form of revolving lines of
credit for seasonal working capital needs. Occasionally, such commitments
are in the form of Letters of Credit to facilitate the customer's
particular business transaction. Commitment fees generally are not charged
except where Letters of Credit are involved. Commitments and lines of
credit typically mature within one year. See also Note 11 of the
Consolidated Notes to the Financial Statements on page 55.

RISK ELEMENTS

The Company closely monitors the markets in which it conducts its lending
Company's primary market areas, in Management's view such impact has not
had a material, adverse effect on the Company's liquidity and capital
resources. The Company continues its strategy to control its exposure to
real estate development loans and increase diversification of credit risk.
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. These occur when known information about possible credit problems
causes Management to have doubts about the ability of such borrowers to
comply with loan repayment terms. These loans have varying degrees of
uncertainty and may become non-performing assets. Classified assets receive
an elevated level of Management attention to ensure collection. Total
classified assets peaked following the second quarter Merger but declined
significantly by December 31, 1993 due to extensive asset write-downs, loan
collections, real estate liquidations and restructurings of the Napa Valley
Bank loan portfolio reflecting the Company's workout strategy.

Non-Performing Assets

Non-performing assets include non-accrual loans, loans 90 days past due and
still accruing, other real estate owned and loans classified as
substantively foreclosed. Loans are placed on non-accrual status upon
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. 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 classied by Management 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
the doubt as to the full collectibility of both interest and principal.
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.

Performing non-accrual loans increased $800,000 to $1.9 million at December
31, 1993. This increase was principally due to one condominium construction
loan. Non-performing non-accrual loans decreased $7.7 million to $7.2
million at December 31, 1993 due to loan collections, write-downs,
foreclosure of loan collateral and reclassifications to loan collateral
substantively foreclosed. Both loan collateral substantively foreclosed and
other real estate owned declined $16.6 million due to asset write-downs and
liquidations. The amount of gross interest income that would have been
recorded for non-accrual loans for the year ending December 31, 1993, if
all such loans had been current in accordance with their original terms
while outstanding during the period, was $980,000. The amount of interest
income that was recognized on non-accrual loans from cash payments made
during the year ended December 31, 1993 totaled $345,000, representing an
annualized yield of 3.06 percent. Cash payments received which were applied
against the book balance of performing and non-performing non-accrual loans
outstanding at December 31, 1993, totaled $534,000 compared to $104,000 in
1992.

Restructured loans totaled $4,432,000 at December 31, 1993, $319,000 at
December 31, 1992, $2,892,000 at December 31, 1991 $2,200,000, at December

CREDIT LOSS EXPERIENCE


The Company's reserve for loan losses is maintained at a level estimated by
Management to be adequate to provide for losses that can be reasonably
credit loss experience, the amount of past due, non-performing and
classified loans, recommendations of regulatory authorities, prevailing
economic conditions and other factors. Initially, the reserve is allocated
to segments of the loan portfolio based in part on quantitative analyses of
historical credit loss experience. Criticized and classied loan balances
are analyzed using both a linear regression model and standard allocation
percentages. The results of this analysis are applied to current criticized
and classied 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 and are grouped by the
number of days the payment on those loans are delinquent. While these
factors are essentially judgmental and may not be reduced to a mathematical
formula, Management considers that the $25.6 million reserve for loan
losses, which constituted 2.30 percent of total loans at December 31, 1993,
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 reserve levels.

In May 1993, the Financial Accounting Standards Board (FASB) issued
statement No. 114, Accounting by Creditors for Impairment of a Loan (SFAS
114) which addresses the accounting treatment of certain impaired loans and
amends FASB Statements No. 5 and No. 15. SFAS 114 does not address the
overall adequacy of the allowance for loan losses. SFAS 114 is effective
January 1, 1995 but earlier implementation is encouraged.

A loan is considered impaired when, based on current information and
events, it is probable that a creditor will be unable to collect all
amounts due according to the contractual terms of the loan agreement. Under
SFAS 114, impairment is measured based on the present value of the expected
future cash flows discounted at the loans effective interest rate.
Alternatively, impairment may be measured by using the loans observable
market price or the fair value of the collateral if repayment is expected
to be provided solely by the underlying collateral.

The Company intends to implement SFAS 114 in January 1995. The impact of
implementation on the financial statements has not been determined, since
measurement will be contingent upon the inventory of impaired loans
outstanding as of January 1, 1995.

ALLOCATION OF RESERVE FOR LOAN LOSSES

The reserve for loan losses has been established to absorb possible future
losses throughout the loan portfolio and off balance sheet credit risk. The
Company's reserve for loan losses is maintained at a level estimated by
management to be adequate to provide for losses that are reasonably
foreseeable based upon specific conditions and other factors. The reserve
is allocated to segments of the loan portfolio based in part upon
quantitative analyses of historical net losses relative to loan balances
outstanding. Criticized and classified loan balances, as identified by
management using criteria similar to those used by the Banks' regulators,
and historical net losses on those balances are analyzed using both a
linear regression and standard allocation percentages model. The results of
this statistical analysis are applied to current criticized and classified
loan balances to allocate the reserve for loan losses to the respective
segments of the loan portfolio. In addition, homogeneous loans, which are
not usually criticized using regulatory guidelines due to their small
balances and numerous accounts, are analyzed based on historical rates of
net loan losses experienced for loans grouped by the number of days
payments are delinquent. Such rates of net loan losses are applied to the
current aging of homogeneous loans to allocate the reserve for loan losses.
Management may judgmentally adjust the allocation of the reserve for loan
losses based on changes in underwriting standards, anticipated rates of net
loan losses which may differ from historical experience, economic
conditions, the experience of credit officers and any other factors
considered pertinent. Management's continuing evaluation of the loan
portfolio and assessment of current economic conditions will dictate future
reserve levels.

balance on the dates indicated:

The reduced allocation to commercial loans from December 31, 1992 to
December 31, 1993 is primarily due to a reduction in the balance of
criticized loans. The increased allocation to construction loans over the
same period is attributable to an increase in criticized loans due to the
recessionary environment. The increase in the unallocated portion of the
reserve is due to the establishment of an additional "recessionary reserve"
to recognize the potential for increased chargeoffs. The changes in the
allocation to loan portfolio segments from December 31, 1991 to December
31, 1992 reflect changes in criticized and classified loan balances. The
decreased allocation to construction loans is attributable to a decrease in
criticized loans due to full collection or principal reducing payments
received from customers. The increased allocation to commercial and
consumer loans is attributable to a reduced level of recoveries.

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 principal
sources of asset liquidity are investment securities available for sale. At
December 31, 1993, investment securities available for sale totaled $168.8
million.

The Company generates significant liquidity from its operating activities.
The Company's profitability in 1993, 1992 and 1991 generated substantial
increases in the cash flow provided from operations for such years to $28.4
million, $33.4 million and $26.7 million, respectively.

Additional cash flow is provided by financing activities, primarily the
acceptance of customer deposits and short-term borrowings from banks. After
a considerable increase in deposits in 1991 of $66.2 million, growth was
only $600,000 in 1992 and the Company experienced a decline of $58.7
million in 1993 mostly due to deposits sold in connection with the sale of
Sonoma Valley Bank. In addition to a $57.0 million compensating increase in
short-term borrowings in 1993, Westamerica Bank issued in December a
ten-year, $20.0 million subordinated capital note that qualifies as Tier II
Capital and will be used as a source of liquidity for working capital
purposes.

The Company uses cash flows from operating and financing activities to make
investments in loans, money market assets and investment securities.
Continuing with the strategy to reduce its exposure to real estate
development loans, net loan repayments were $68.1 million, $32.8 million
and $15.5 million in 1993, 1992 and 1991, respectively. The net repayment
of loans resulted in added liquidity for the Company, which was used to
increase its investment securities portfolios by $153.4 million, $75.8
million and $130.0 million in 1993, 1992 and 1991, respectively.

Interest rate risk is influenced by market forces. However, that risk may
be controlled by monitoring and managing the repricing characteristics of
assets and liabilities. In evaluating exposure to interest rate risk, the
Company considers the effects of various factors in implementing interest
rate risk management activities, including the utilization of interest rate
swaps. Interest rate swaps outstanding at December 31, 1993 had aggregate
notional amounts of $110.0 million of which $50.0 million matures in 1994
and $60.0 million matures in 1995. These interest rate swaps were entered
into to hedge the adverse impact interest rate fluctuations have on
interest-bearing transaction and savings deposits in the current interest
rate environment.

The primary analytical tool used by Management to gauge interest-rate
sensitivity is a simulation model used by many major banks and bank
regulators. This industry standard model is used to simulate the effects on
net interest income of changes in market interest rates that are up to 2
percent higher or 2 percent lower than current levels. The results of the
model indicate that the mix of interest rate sensitive assets and
liabilities at December 31, 1993 would not, in the view of Management,
expose the Company to an unacceptable level of interest rate risk.

CAPITAL RESOURCES

The Company's capital position represents the level of capital available to
support continued operations and expansion. The Company's primary captial
resource is shareholders' equity, which increased $8.8 million or 6.1
percent from the previous year end and increased $23.0 million or 17.8
percent from December 31, 1991.

As a result of the Company's profitability, the retention of earnings and
slow asset growth, the ratio of equity to total assets increased to 7.6
percent at December 31, 1993, up from 7.3 percent at December 31, 1992 and
6.6 percent at December 31, 1991. Tier I risk-based capital to
risk-adjusted assets increased to 11.11 percent at December 31, 1993, from
10.02 percent at year end 1992. The ratio of total risk-based capital to
risk-adjusted assets increased to 14.40 percent at December 31, 1993, from
12.01 percent at December 31, 1992.

Tier I Capital 11.11% 10.02% 4.00%
Total Capital 14.40 12.01 8.00
Leverage ratio 7.42 7.39 4.00

The risk-based capital ratios improved in 1993 due to two factors: equity
capital grew at a faster rate than total assets, and the decline in loan
volumes and increase in investment securities reduced the level of
risk-adjusted assets.

- -----------------------------------------------------------------------
Total $ 23.9 $ 23.8 $ 24.0
=======================================================================

Non-interest income increased to $23.9 million in 1993. Higher income from
servicing automobile receivables, the sale of the Company's 50 percent
interest in Sonoma Valley Bank, higher brokerage commissions, increased
fees from deposit services, gains recognized on the sale of Napa Valley
Bancorp cardholder portfolio and lower write-offs of mortgage service
receivables, were partially offset by lower credit card merchant fees and
lower mortgage servicing fees. 1992 non-interest income also reflects $1.1
million gains on the sale of investment securities held for sale. In 1992,
non-interest income decreased $200,000 from the previous year, resulting
principally from lower gains of investment securities held-for-sale and
lower income from servicing automobile receivables partially offset by
higher deposit account fees, mortgage banking income and brokerage
commissions.

Non-interest expense increased $7.0 million or 8 percent in 1993 compared
with an increase of $4.7 million or 6 percent in 1992. The increase in 1993
is the direct result of merger-related foreclosed real estate owned
expenses, reflecting a $10.0 million write-down of assets acquired in the
Merger to fair value net of estimated selling costs reflecting the
implementation of the Company's workout strategy, and other costs
associated with the Merger, including $1.2 million in relocation costs,
chargeoffs of $921,000 for obsolete furniture and equipment, $745,000 in
investment banker fees, and other merger-related costs totaling
approximately $1.2 million. Partially offsetting these increases in 1993
non-interest expense, salaries decreased $2.1 million, or 6 percent,
reflecting the benefits realized from consolidation of operations after the
Merger. Merchant credit card, professional fees and insurance expenses also
decreased from 1992.

The ratio of average assets per full-time equivalent staff was $2.2 million
in 1993 compared to $1.8 million in 1992; the Company strategy to improve
efficiency can be clearly seen in the reduction of the average number of
full-time equivalent staff from 1,092 in 1992 to 905 in 1993.

PROVISION FOR INCOME TAX

The provision for income tax decreased $4.9 million in 1993 as a direct
result of lower pretax income and a $394,000 revaluation adjustment of
deferred tax assets due to an increase in statutory tax rates. The
provision was $3.0 million in 1993 compared to $7.9 million in 1992 and
$5.8 million in 1991. The higher provision in 1992 is a direct result of
higher pretax income.

Westamerica Bancorporation
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Business and Accounting Policies

Westamerica Bancorporation, a registered bank holding Company, (the
Company), provides a full range of banking services to individual and
corporate customers in Northern California through its subsidiary banks
(the Banks), Westamerica Bank and Subsidiary, Bank of Lake County and Napa
Valley Bank and Subsidiary. The Banks are subject to competition from other
financial institutions and to regulations of certain agencies and undergo
periodic examinations by those regulatory authorities.

Summary of Significant Accounting Policies

The consolidated financial statements are prepared in conformity with
generally accepted accounting principles and general practices within the
banking industry. The following is a summary of significant accounting
policies used in the preparation of the accompanying financial statements.
In preparing the financial statements, Management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities as of the dates of the balance sheets and revenues and expenses
for the periods indicated.

Principles of Consolidation. The financial statements include the accounts of
the Company, a registered bank holding company, and all the Company's
subsidiaries which include the Banks and Community Banker Services
Corporation and Subsidiary. Significant intercompany transactions have been
eliminated in consolidation. All data has been restated on an historical
basis to reflect the April 15, 1993 acquisition of Napa Valley Bancorp on a
pooling-of-interests basis.

Cash Equivalents. Cash equivalents include Due From Banks balances and
Federal Funds Sold which are both readily convertible to known amounts of
cash and are so near their maturity that they present insignificant risk of
changes in value because of interest rate volatility.

Securities. Marketable investment securities at December 31, 1993 consist
of U.S. Treasury, U. S. Government Agencies and Corporations, Municipal,
asset-backed and other securities. The Company adopted the provisions of
Statement of Financial Accounting Standards No. 115, Accounting for Certain
Investments in Debt and Equity Securities (SFAS No. 115) at December 31,
1993. Under SFAS No. 115, the Company classifies its debt and marketable
equity securities into one of three categories: trading, available-for-sale
or held-to-maturity. Trading securities are bought and held principally for
the purpose of selling in the near term. Held-to-maturity securities are
those securities which the Company has the ability and intent to hold until
maturity. All other securities not included in trading or held-to-maturity
are classied as available-for-sale.

Trading and available-for-sale securities are recorded at fair value.
Held-to-maturity securities are recorded at amortized cost, adjusted for
the amortization or accretion of premiums or discounts.

Unrealized gains and losses on trading securities are included in earnings.
Unrealized gains and losses, net of the related tax effect, on
available-for-sale securities are excluded from earnings and are reported
as a separate component of shareholders' equity until realized.

Unrealized gains and losses associated with transfers of securities from
held-to-maturity to available-for-sale are recorded as a separate component
of shareholders' equity. The unrealized gains or losses included in the
separate component of shareholders' equity for securities transferred from
available-for-sale to held-to-maturity are maintained and amortized into
earnings over the remaining life of the security as an adjustment to yield
in a manner consistent with the amortization or accretion of premium or
discount on the associated security.

A decline in the market value of held-to-maturity and available-for-sale
securities below cost that is deemed other than temporary, results in a
charge to earnings and the establishment of a new cost basis for the
security.

Premiums and discounts are amortized or accreted over the life of the
related investment security as an adjustment to yield using the effective
interest method. Dividend and interest income are recognized when earned.
Realized gains and losses for securities classied as available-for-sale and
held-to-maturity are included in earnings and are derived using the
specific identification method for determining the cost of securities sold.

Loans and Reserve for Loan Losses. The reserve for loan losses is a
combination of specific and general reserves available to absorb estimated
future losses in the loan portfolio and is maintained at a level considered
adequate to provide for such losses. Credit reviews of the loan portfolio,
designed to identify problem loans and to monitor these estimates, are
conducted continually, taking into consideration market conditions, current
and anticipated developments applicable to the borrowers and the economy,
and the results of recent examinations by regulatory agencies. Management
approves the conclusions resulting from credit reviews. Ultimate losses may
vary from current estimates. Adjustments to previous estimates of loan
losses are charged to income in the period which they become known.

Unearned interest on discounted loans is amortized over the life of these
loans, using the sum-of-the-months digits method for which the results are
not materially different from those obtained by using the interest method.
For all other loans, interest is accrued daily on the outstanding balances.
Loans which are more than 90 days delinquent with respect to interest or
principal, unless they are well secured and in the process of collection,
and other loans on which full recovery of principal or interest is in
doubt, are placed on non-accrual status.

Non-refundable fees and certain costs associated with originating or
acquiring loans are deferred and amortized as an adjustment to interest
income over the estimated respective loan lives. Loans held for sale are
identified upon origination and are reported at the lower of cost or fair
value on an individual loan basis.

Other Real Estate Owned and Loan Collateral Substantively Foreclosed. Other
real estate owned includes property acquired through foreclosure or
forgiveness of debt. These properties are transferred at fair value, which
becomes the new cost basis of the property. Losses recognized at the time
of acquiring property in full or partial satisfaction of loans are charged
against the reserve for loan losses. Subsequent losses incurred due to the
declines in property values as identified in independent property
appraisals are recognized as non-interest expense. Routine holding costs,
such as property taxes, insurance and maintenance, and losses from sales
and dispositions are recognized as non-interest expense.

The Company classifies loans as loan collateral substantively foreclosed
(substantive repossessions) when the borrower has little or no equity in
the collateral, when proceeds for repayment of the loan can be expected to
come only from the operation or sale of the collateral, and the debtor has
either formally or effectively abandoned control of the collateral to the
Company or has retained control of the collateral but, because of the
current financial condition of the debtor or the economic prospects for the
debtor and/or collateral in the foreseeable future, it is doubtful that the
debtor will be able to rebuild equity in the collateral or otherwise repay
the loan in the foreseeable future. Losses recognized at the time the loans
are reclassified as substantive repossessions are charged against the
reserve for loan losses. Subsequent losses incurred due to subsequent
declines in property values, as identified in independent property
appraisals, are recognized as non-interest expense. Routine holding costs,
such as property taxes, insurance and maintenance, and losses from sales
and dispositions are recognized as non-interest expense.

Premises and Equipment. Premises and equipment are stated at cost, less
accumulated depreciation and amortization. Depreciation is computed on the
straight-line method over the estimated useful life of each type of asset.
Estimated useful lives of premises and equipment range from 20 to 50 years
and from 3 to 20 years, respectively. Leasehold improvements are amortized
over the terms of the lease or their estimated useful life, whichever is
shorter. Fully depreciated and/or amortized assets are removed from the
Company's balance sheet.

Interest Rate Swap Agreements. The Company uses interest rate swap
agreements as an asset/liability management tool to reduce interest
rate risk. Interest rate swap agreements are exchanges of fixed and
variable interest payments based on a notional principal amount. The
primary risk associated with swaps is the exposure to movements in interest
rates and the ability of the counter parties to meet the terms of the
contracts. The Company controls the credit risk of the these agreements
through credit approvals, limits and monitoring procedures. The Company is
not a dealer but an end user of these instruments and does not use them
speculatively.

Accounted for as hedges, the differential to be paid or received on such
agreements is recognized over the life of the agreements. Payments made or
received in connection with early termination of interest rate swap
agreements are recognized over the remaining term of the swap agreement.

Earnings Per Share. Earnings per share amounts are computed on the basis of
the weighted average of common shares outstanding during each of the years
presented.

Income Taxes. The Company and its subsidiaries file consolidated tax
returns. For financial reporting purposes, the income tax effects of
transactions are recognized in the year in which they enter into the
determination of recorded income, regardless of when they are recognized
for income tax purposes. Accordingly, the provisions for income taxes in
the consolidated statements of income include charges or credits for
deferred income taxes relating to temporary differences between the tax
basis of assets and liabilities and their reported amounts in the financial
statements.

Other. Securities and other property held by the Banks in a fiduciary or
agency capacity are not included in the financial statements since such
items are not assets of the Company or its subsidiaries. Certain amounts in
prior years financial statements have been reclassified to conform with the
current years presentation. These reclassifications had no effect on
previously reported income.

Note 7: Shareholders' Equity

In April 1982, the Company adopted an Incentive Stock Option Plan and
413,866 shares were reserved for issuance. Under this plan, all options are
currently exercisable and terminate 10 years from the date of the grant.
Under the Stock Option Plan adopted by the Company in 1985, 750,000 shares
have been reserved for issuance. Stock appreciation rights, incentive stock
options, non-qualified stock options and restricted performance shares are
available under this plan. Options are granted at fair market value and are
generally exercisable in equal installments over a three-year period with
the first installment exercisable one year after the date of the grant.
Each incentive stock option has a maximum ten-year term while non-qualified
stock options may have a longer term. The 1985 plan was amended in 1990 to
provide for restricted performance share (RPS) grants. An RPS grant becomes
fully vested after three years of being awarded, provided that the Company
has attained its performance goals for such three-year period. At December
31, 1993, 299,046 options were available for grant under the 1985 Stock
Option Plan.

Information with respect to options outstanding and options exercised under
the plans is summarized in the following table:

Number Option Price

Shares under option at December 31:
1993 313,564 8.88- 24.50 5,766,400

* Issuable upon exercise.

At December 31, 1993, options to acquire 164,794 shares of common stock
were exercisable.

Shareholders have authorized issuance of two new classes of 1,000,000
shares each, to be denominated Class B Common Stock and Preferred Stock,
respectively, in addition to the 20,000,000 shares of Common Stock
presently authorized. At December 31, 1993, no shares of Class B or
Preferred Stock had been issued. At December 31, 1993, the Company's Tier I
Capital was $149,937,000 and Total Capital was $194,415,000 or 11.11
percent and 14.40 percent, respectively, of risk-adjusted assets.

In December 1986, the Company declared a dividend distribution of one
common share purchase right (the Right) for each outstanding share of
common stock. The Rights are exercisable only in the event of an
acquisition of, or announcement of a tender offer to acquire, 15 percent or
more of the Company's stock or 50 percent or more of its assets without the
prior consent of the Board of Directors. If the Rights become exercisable,
the holder may purchase one share of the Company's common stock for $65.
Following an acquisition of 15 percent of the Company's common stock or 50
percent or more of its assets without prior consent of the Company, each
right will also entitle the holder to purchase $130 worth of common stock
of the Company for $65. Under certain circumstances, the Rights may be
redeemed by the Company at a price of $.05 per right prior to becoming
exercisable and in certain circumstances thereafter. The Rights expire on
December 31, 1999, or earlier, in connection with certain Board-approved
transactions.

Note 8: Income Taxes

Effective January 1, 1992, the Company adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes, (SFAS No. 109).
Adoption of SFAS No. 109 required a change from the deferred method to the
asset and liability method of accounting for income taxes. Under the
deferred method, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement reported amounts of existing assets and liabilities and their
respective tax bases and operating loss and tax credit carry forwards.]
Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled.

The components of the net deferred tax asset as of December 31, are as
follows:

(In thousands) 1993 1992

Total deferred tax liability 3,678 1,544
- -------------------------------------------------------------------
Net deferred tax asset $11,632 $11,839
===================================================================
The Company believes a valuation allowance is not needed to reduce the
deferred tax asset because there is no material portion of the deferred
tax asset that will not be realized through sufficient taxable income.

The provisions for federal and state income taxes consist of amounts
currently payable and amounts deferred which, for the years ended December
31, are as follows:

Note 9: Fair Value of Financial Instruments

The fair value of financial instruments which have a relative short period
of time between their origination and their expected realization were
valued using historical cost. Such financial instruments and their
estimated fair values at December 31, were:

(In thousands) 1993 1992
- -------------------------------------------------------------------
Cash and cash equivalents $102,618 $139,497
Money market assets 250 1,366
Interest and taxes receivable 28,799 25,741
Non-interest bearing and interest-bearing
transaction and savings deposits 1,313,908 1,258,353
Funds purchased 69,064 12,038
Interest payable 2,700 3,824

The fair value at December 31 of the following financial instruments was
estimated using quoted market prices:

(In thousands) 1993 1992
- -------------------------------------------------------------------
Investment securities available for sale $168,819 $ --
Investment securities held to maturity 563,563 581,768
Trading account securities 10 --

Loans were separated into two groups for valuation. Variable rate loans,
which reprice frequently with changes in market rates, were valued using
historical cost. Fixed rate loans 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
$25,587,000 and $24,742,000 reserves for loan losses as of December 31,
1993 and 1992, respectively, were applied against the estimated fair value
to recognize future defaults of contractual cash flows. The estimated fair
market value of loans at December 31, was:

(In thousands) 1993 1992
- --------------------------------------------------------------------
Loans $1,096,164 $1,171,630

The fair value of time deposits and notes and mortgages payable was
estimated by discounting future cash flows related to these financial
instruments using current market rates for financial instruments with
similar characteristics.

The estimated fair values at December 31, were:

(In thousands) 1993 1992
- ---------------------------------------------------------------------
Time deposits $420,475 $534,920
Notes and mortgages payable 36,014 20,282

The estimated fair values of the Company's interest rate swaps, which are
determined by dealer quotes and generally represent the amount that the
Company would pay to terminate its swap contracts, were $(600,000) and $0,
respectively, at December 31, 1993 and 1992.

These fair values do not represent actual amounts that may be realized upon
any sale or liquidation of the related assets or liabilities. 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 fair values
presented above represent the Company's best estimate of fair value using
the methodologies discussed above.

Note 10: Lease Commitments

Fifteen banking offices and three administrative service centers are owned
and thirty-seven banking offices and two support facilities are leased.
Substantially all the leases contain multiple renewal options and
provisions for rental increases, principally for changes in the cost of
living, property taxes and maintenance. The Company also leases certain
pieces of equipment. Minimum future rental payments on operating leases,
net of sublease income, at December 31, 1993, are as follows:

(In thousands)
1994 $ 3,253
1995 3,091
1996 2,632
1997 1,679
1998 1,183
Thereafter 3,659
- -------------------------------------------------
Total minimum lease payments $15,497
=================================================

Total rentals for premises and equipment net of sublease income included in
non-interest expense were $3,862,000 in 1993, $3,910,000 in 1992 and
$3,829,000 in 1991.

Note 11: 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 $159.2
million at December 31, 1993.

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 were $6.4
million at December 31, 1993.

Interest rate swaps are agreements to exchange interest payments computed
on notional amounts. The notional amounts do not represent exposure to
credit risk; however, these agreements expose the Company to market risks
associated with fluctuations of interest rates. As of December 31, 1993,
the Company had entered into four interest rate swaps. The first two
contracts have notional amounts totaling $25 million each and the second
two contracts have notional amounts totaling $30 million each. On the first
two contracts, which are scheduled to terminate in November and December of
1994, the Company pays an average fixed rate of interest of 5.06 percent
and receives a variable rate of interest based on the London Interbank
Offering Rate (LIBOR); on the second two contracts, scheduled to terminate
in August of 1995, the Company pays a variable rate based on LIBOR and
receives an average fixed rate of interest of 4.11 percent.

The LIBOR rate has averaged 3.39 percent from the date the first two swaps
were entered through December 31, 1993 and 3.33 percent from the date the
second two swaps were entered through December 31, 1993. The effect of
entering into these contracts resulted in a decrease to net interest income
of $659,000 for the period ended December 31, 1993.

The Company, because of the nature of its business, is subject to various
threatened or filed legal cases. The Company, based on the advice of legal
counsel, does not expect such cases will have material, adverse effect on
its financial position or results of operations.

Note 12: Retirement Benefit Plans

The Company sponsors a defined benefit Retirement Plan covering
substantially all of its salaried employees with one or more years of
service. The Company's policy is to expense costs as they accrue as
determined by the Projected Unit Cost method. The Company's funding policy
is to contribute annually the maximum amount that can be deducted for
federal income tax purposes.

The following table sets forth the Retirement Plans funded status as of
December 31 and the pension cost for the years ended December 31:

Actual return on plan assets (1,012) (686)
Net amortization and deferral 64 (271)
- -----------------------------------------------------------------
Net periodic pension cost $160 $181
=================================================================

The discount rate and rate of increase in future compensation levels used
in determining the actuarial present value of the projected benefit
obligation were 6.75 percent and 5 percent, respectively, at December 31,
1993 and 7 percent and 5 percent, respectively, at December 31, 1992. The
expected long-term rate of return on plan assets in 1993 and 1992 was 7
percent and 8 percent, respectively.

Effective January 1, 1992, the Company adopted a defined contribution
Deferred Profit-Sharing Plan covering substantially all of its salaried
employees with one or more years of service. Participant deferred
profit-sharing account balances offset benefits accrued under the
Retirement Plan which was amended effective January 1, 1992 to coordinate
benefits with the Deferred Profit-Sharing Plan. The coordination of
benefits results in the Retirement Plan benefit formula establishing the
minimum value of participant retirement benefits which, if not provided by
the Deferred Profit-Sharing Plan, are guaranteed by the Retirement Plan.

The costs charged to non-interest expense related to benefits provided by
the Retirement Plan and the Deferred Profit-Sharing Plan were $1,160,000 in
1993, $1,037,000 in 1992 and $759,000 in 1991.

In addition to the Retirement Plan and the Deferred Profit-Sharing Plan,
all salaried employees are eligible to participate in the voluntary Tax
Deferred Savings/Retirement Plan (ESOP) upon completion of a 90-day
introductory period. This plan allows employees to defer, on a pretax
basis, a portion of their compensation as contributions to the plan.
Participants are allowed to invest in five funds, including a Westamerica
Bancorporation Common Stock Fund. The Company's matching contributions
charged to operating expense were $482,000 in 1993, $462,000 in 1992 and
$452,000 in 1991.

Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 106, Employers Accounting for Postretirement
Benefits Other than Pensions (SFAS No. 106). Adoption of SFAS No. 106
required a change from the cash method to an actuarial based accrual method
of accounting for postretirement benefits other than pensions. The Company
offers continuation of group insurance coverage to employees electing early
retirement, as defined by the Retirement Plan, for the period from the date
of early retirement until age sixty-five. The Company contributes an amount
toward early retirees insurance premiums which is fixed at the time of
early retirement. The Company also reimburses Medicare Part B premiums for
all retirees over age sixty-five, as defined by the Retirement Plan.

The following table sets forth the net periodic postretirement benefit cost
for the year ended December 31, 1993 and the funded status of the plan at
December 31, 1993:

Unrecognized transition obligation 1,471
Recognized postretirement obligation 82
- -----------------------------------------------------------
Total $1,553
===========================================================
The discount rate used in measuring the accumulated postretirement benefit
obligation was 6.75 percent at December 31, 1993. The assumed health care
cost trend rate used to measure the expected cost of benefits covered by
the plan was 9 percent for 1994 and declined steadily to an ultimate trend
rate of 4 percent beginning in 1999. The effect of a one percentage point
increase on the assumed health care cost trend for each future year would
increase the aggregate of the service cost and interest cost components of
the 1993 net periodic cost by $73,000 and increase the accumulated
postretirement benefit obligation at December 31, 1993 by $204,000.

Note 13: Related Party Transactions

Certain directors and executive officers of the Company were lending
customers of the Company during 1993 and 1992. All such loans were made in
the ordinary course of business on normal credit terms, including interest
rates and collateral requirements. No related party loan represents more
than normal risk of collection. Such loans were $5,238,000 and $10,591,000
at December 31, 1993 and 1992, respectively.

Note 14: Restrictions

Payment of dividends to the Company by Westamerica Bank, the largest
subsidiary bank, is limited under regulations for Federal Reserve member
banks. The amount that can be paid in any calendar year, without prior
approval from regulatory agencies, cannot exceed the net profits (as
defined) for that year plus the net profits of the preceding two calendar
years less dividends declared. Under this regulation, Westamerica Bank, the
largest subsidiary bank, was not restricted as to the payment of $13.6
million in dividends to the Company as of December 31, 1993. During 1992
and 1993, Napa Valley Bank, a banking subsidiary, was operating under a
regulatory order which disallowed payment of dividends to the Company
unless it reduced the level of problem assets, liquidated, or reserved
adequately against, the real estate investments in its subsidiary company,
and strengthened its loan loss reserve. Napa Valley Bank has complied with
all conditions of the regulatory order which will be removed by the
regulators based on their fourth quarter 1993 examination. Payment of
dividends by the Company is also restricted under the terms of the note
agreements as discussed in Note 6. Under the most restrictive of these
agreements, $17.1 million was available for payment of dividends as of
December 31, 1993. Under one of the note agreements, the Company has agreed
to limit its funded debt to 40 percent of the total of funded debt plus
shareholders' equity and maintain certain other financial ratios. The
Company was in compliance with all such requirements as of December 31,
1993.

The Banks are required to maintain reserves with the Federal Reserve Bank
equal to a percentage of its reservable deposits. The Banks daily average
balance on deposit at the Federal Reserve Bank was $40.4 million in 1993
and $40.3 million in 1992.

Note 17: Acquisition

On April 15, 1993, the Company issued approximately 2,122,740 shares of its
common stock in exchange for all of the outstanding common stock of Napa
Valley Bancorp, a bank holding company, whose subsidiaries included Napa Valley
Bank ("NVB"), a California-based, state-chartered banking association, and
Subsidiary, 88 percent interest in Bank of Lake County ("BLC"), a national
banking association, 50 percent interest in Sonoma Valley Bank, a state banking
association, Suisun Valley Bank, also a state chartered bank, and Napa Valley
Bancorp Services Corporation ("NVBSC"), estabilshed to provide data processing
and other services to Napa Valley Bancorp's subsidiaries. This business
transaction (the "Merger") was accounted for as a pooling-of-interests
combination and, accordingly, the consolidated financial statements and
financial data for periods prior to the combination have been restated to
include the accounts and results of operations of Napa Valley Bancorp.
Certain reclassifications have been made to Napa Valley Bancorp to conform to
Westamerica Bancorporation's presentation. Subsequent to the
combination, Westamerica Bancorporation sold the 50 percent interest in
Sonoma Valley Bank at a gain of $668,000. This business combination has
been accounted for as a pooling-of-interests combination; and, accordingly,
the consolidated financial statements and financial data for periods prior
to the combination have been restated to include the accounts and results
of operations of Napa Valley Bancorp. Certain reclassification have been
made to Napa Valley Bancorp to conform to Westamerica Bancorporation's
presentation.

The results of operations previously reported by the separate enterprises
and the combined amounts presented in the accompanying consolidated
financial statements are summarized as follows.

* As originally reported.

Net income per share was reduced $.25 for the three months ended March 31,
1993, $.48 in 1992, and $.54 in 1991, attributable to dilution from shares
issued in connection with the acquisition. In addition, net income of the
Company for 1993 was reduced by an estimated $8.3 million due to the
consolidation of Napa Valley Bancorp's branches and operations, certain
merger-related expenses and the application of Westamerica Bancorporation's
workout strategy to the non-performing assets of Napa Valley Bancorp.

There were no significant transactions between Westamerica Bancorporation
and Napa Valley Bancorp prior to the combination.

MANAGEMENTS LETTER OF FINANCIAL RESPONSIBILITY

To the Shareholders:

The Management of Westamerica Bancorporation is responsible for the
preparation, integrity, reliability and consistency of the information
contained in this annual report. The financial statements, which
necessarily include amounts based on judgments and estimates, were prepared
in conformity with generally accepted accounting principles and prevailing
practices in the banking industry. All other financial information
appearing throughout this annual report is presented in a manner consistent
with the financial statements.

Management has established and maintains a system of internal controls that
provides reasonable assurance that the underlying financial records are
reliable for preparing the financial statements, and that assets are
safeguarded from unauthorized use or loss. This system includes extensive
written policies and operating procedures and a comprehensive internal
audit function, and is supported by the careful selection and training of
staff, an organizational structure providing for division of
responsibility, and a Code of Ethics covering standards of personal and
business conduct. Management believes that, as of December 31, 1993 the
Corporation's internal control environment is adequate to provide
reasonable assurance as to the integrity and reliability of the financial
statements and related financial information contained in the annual
report.

The system of internal controls is under the general oversight of the Board
of Directors acting through its Audit Committee, which is comprised
entirely of outside directors.

The Audit Committee monitors the effectiveness of and compliance with
internal controls through a continuous program of internal audit and credit
examinations. This is accomplished through periodic meetings with
Management, internal auditors, loan quality examiners, regulatory examiners
and independent auditors to assure that each is carrying out their
responsibilities.

The Corporation's financial statements have been audited by KPMG Peat
Marwick, independent auditors elected by the shareholders. All financial
records and related data, as well as the minutes of shareholders and
directors meetings, have been made available to them. Management believes
that all representations made to the independent auditors during their
audit were valid and appropriate.

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders of Westamerica Bancorporation

We have audited the accompanying consolidated balance sheets of Westamerica
Bancorporation and subsidiaries as of December 31, 1993 and 1992, and the
related consolidated statements of income, changes in shareholders' equity,
and cash flows for each of the years in the three year period ended
December 31, 1993. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits. As discussed in Note 1 to the consolidated financial statements,
the consolidated balance sheet of the Company as of December 31, 1992 and
the related statements of income, changes in shareholders' equity, and cash
flows for each of the years in the two year period ended December 31, 1992,
and the related footnote disclosures have been restated on an historical
basis to reflect the April 15, 1993 acquisition of Napa Valley Bancorp on a
pooling-of-interests basis. We did not audit the financial statements of
Napa Valley Bancorp as of and for the periods ended December 31, 1992 and
1991, which statements reflect total assets constituting 30 percent in 1992
and net income constituting 8 percent and 2 percent in 1992 and 1991,
respectively, of the related and restated consolidated totals. Those
statements included in the 1992 and 1991 restated consolidated totals were
audited by other auditors whose report has been furnished to us, and our
opinion, insofar as it relates to the amounts included for Napa Valley
Bancorp, is based solely on the report of the other auditors.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits and
the report of the other auditors provide a reasonable basis for our
opinion.

In our opinion, based on our audits and the report of the other auditors,
the consolidated financial statements referred to above present fairly, in
all material respects, the financial position of Westamerica Bancorporation
and subsidiaries as of December 31, 1993 and 1992, and the results of their
operations and their cash flows for each of the years in the three year
period ended December 31, 1993 in conformity with generally accepted
accounting principles.
