                              FORWARD-LOOKING STATEMENTS

This report on Form 10-Q contains forward-looking statements about Westamerica
Bancorporation for which it claims the protection of the safe harbor provisions
contained in the Private Securities Litigation Reform Act of 1995. These
forward-looking statements are based on Management's current knowledge and
belief and include information concerning the Company's possible or assumed
future financial condition and results of operations. A number of factors, some
of which are beyond the Company's ability to predict or control, could cause
future results to differ materially from those contemplated. These factors
include but are not limited to (1) continued weakness in the national and
California economies; (2) increased economic uncertainty created by concerns
regarding terrorist attacks and geopolitical risks; (3) the prospect of
additional terrorist attacks in the United States and the uncertain effect of
these events on the national and regional economies; (4) changes in the interest
rate environment; (5) changes in the regulatory environment; (6) significantly
increasing competitive pressure in the banking industry; (7) operational risks
including data processing system failures or fraud; (8) the effect of
acquisitions and integration of acquired businesses; (9) volatility of rate
sensitive assets and liabilities; (10) asset/liability management risks and
liquidity risks; and (11) changes in the securities markets.

The reader is directed to the Company's Annual Report on Form 10-K for the year
ended December 31, 2002, for further discussion of factors which could affect
the Company's business and cause actual results to differ materially from those
expressed in any forward-looking statement made in this report. The Company
undertakes no obligation to update any forward-looking statements in this
report.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and pursuant to the rules and regulations of the
Securities and Exchange Commission. The results of operations reflect interim
adjustments, all of which are of a normal recurring nature and which, in the
opinion of Management, are necessary for a fair presentation of the results for
the interim period presented. The interim results for the three and nine months
ended September 30, 2003 and 2002 are not necessarily indicative of the results
expected for the full year. These unaudited consolidated financial statements
should be read in conjunction with the audited consolidated financial statements
and accompanying notes as well as other information included in the Company's
Annual Report on Form 10-K for the year ended December 31, 2002.

Note 2: Significant Accounting Policies

Certain accounting policies underlying the preparation of these financial
statements require Management to make estimates and judgments. These estimates
and judgments may affect reported amounts of assets and liabilities, revenues
and expenses, and disclosures of contingent assets and liabilities. The most
significant of these involve the Allowance for Loan Losses, which is discussed
in Note 1 to the audited consolidated financial statements included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2002.

Note 3: Goodwill and Other Intangible Assets

The Company has recorded goodwill and core deposit intangibles associated with
purchase business combinations and, effective January 1, 2002, accounts for them
in accordance with Statement of Financial Accounting Standards No. 142, Goodwill
and Other Intangible Assets. Accordingly, goodwill is no longer being amortized,
but is periodically evaluated for impairment. During 2003, no impairment of
goodwill has been recorded. Core deposit intangibles are amortized to
their estimated residual values over their expected useful lives; such lives and
residual values are also periodically reassessed to determine if any
amortization period adjustments are indicated. The Company determined that no
such adjustments were required as of September 30, 2003.

The following table summarizes the Company's goodwill and core deposit
intangible assets, which are included with interest receivable and other assets
in the Consolidated Balance Sheets, as of January 1, 2003 and September 30, 2003
(dollars in thousands).

  $165, $543, $469, $427, $427 and $427, respectively. The weighted average
  amortization period for core deposit intangibles is 8.5 years.

Note 4: Stock Options

As permitted by Statement of Financial Accounting Standards ("SFAS") No. 123
"Accounting for Stock-Based Compensation", the Company accounts for its
stock option plans using the intrinsic value method. Accordingly,
compensation expense is recorded on the grant date only if the current
price of the underlying stock exceeds the exercise price of the option.
Had compensation cost been determined based on the fair value method
established by SFAS 123, the Company's net income and earnings per share
would have been reduced to the pro forma amounts indicated below:

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

Westamerica Bancorporation and subsidiaries (the "Company") reported
third quarter 2003 net income of $24.1 million or diluted earnings per
share of $0.72. These results compare with third quarter 2002 net income
of $22.9 million or $0.67 per share.

On a year-to-date basis, the Company reported net income for the nine
months ended September 30, 2003 of $70.8 million or diluted earnings per
share of $2.12, compared with $63.9 million or $1.86 per share for the
same period of 2002. The year-to-date results in 2002 included after-tax
expenses in connection with the acquisition of Kerman State Bank ("KSB")
($230 thousand) and after-tax securities impairment charge ($2.5
million) incurred in the second quarter of 2002.

Following is a summary of the components of income from certain
securities and loans is presented on a fully taxable equivalent ("FTE")
basis to reflect its exemption from federal income taxation for the
periods indicated (dollars in thousands).

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


Net income for the third quarter of 2003 was $1.2 million or 5.2% more
than the same quarter of 2002 primarily due to lower net interest income
(down $650 thousand), higher noninterest income (up $558 thousand or
5.3%), a decline in noninterest expense of $430 thousand or 1.7% and
lower income taxes which were down $708 thousand or 4.5% on an FTE
basis. The decrease in net interest income (FTE) was attributable to a
40 basis point ("bp") decline in the net interest margin, partially
offset by the effect of higher average earning assets which were up
$243.9 million. Noninterest income increased primarily due to growth in
fee income, and included $2.2 million securities gains, neutralized by
$2.2 million FHLB advance prepayment fees. Noninterest expense declined
mostly because of lower personnel costs. The lower tax provision was the
result of higher low-income housing investments and other tax credits.

Comparing the first nine months of 2003 to the prior year, net income
rose $6.9 million or 10.8%. The increase was primarily attributable to
higher noninterest income (up $6.1 million or 23.2%) resulting from a
securities impairment charge in 2002, and increased deposit fee income,
improved net interest income (FTE) (up $1.9 million or 1.2%) and $1.0
million savings from noninterest expense, partially reduced by higher
taxes (up $2.3 million or 5.4% on an FTE basis). The increase in net
interest income was mostly caused by higher average earning assets (up
$288.9 million or 7.8%), partially reduced by a 35 bp net interest
margin reduction. The decrease in noninterest expense was mainly due to
lower personnel costs. Noninterest expense in 2002 included a $400
thousand expense relating to the KSB acquisition.

Net interest income (FTE) during the third quarter of 2003 decreased
$650 thousand (1.2%) from the same period in 2002, to $54.3 million. The
decrease was mainly attributable to the effect of a lower net interest
margin earned (the rate component), partially offset by a $243.9 million
increase in average earning assets (the volume component). The decrease
in the net interest margin was the net effect of an 82 bp drop in the
asset yield, which was partly recovered by a 59 bp decline in the cost
of funds.

Comparing the first nine months of 2003 with the prior year, net
interest income (FTE) rose $1.9 million or 1.2%. The increase was caused
by the net effect of higher average earning assets (up $288.9 million)
and a declining margin. The margin reduction was the result of a 74 bp
decrease in the asset yield reduced by a 55 bp decline in the cost of
funds.


Interest and Fee Income

Interest & fee income (FTE) for the third quarter of 2003 decreased $4.4
million (6.7%) from the same period in 2002. The decline was the net
effect of higher average earning assets in 2003, more than offset by
lower yields earned on those assets. Average earning assets grew $243.9
million (6.4%). The earning asset growth was led by expansion in the
investment portfolio of $404.0 million as follows: mortgage backed
securities and collateralized mortgage obligations (up $204.4 million),
US Agency obligations (up $185.5 million) and municipal securities (up
$184.1 million). Offsetting the increase were declines in U.S. Treasury
securities (down $85.4 million) and other securities (down $83.7
million). The growth in the earning assets was diminished by a $160.2
million reduction in loans including commercial real estate loans (down
$116.9 million), commercial loans (down $32.0 million), direct consumer
loans (down $15.9 million) and construction loans (down $11.9 million).
The exception to the lower loan amount was an increase in residential
real estate loans (up $17.0 million).

The average yield on the Company's earning assets decreased for the
third quarter from 6.74% in 2002 to 5.92% in 2003 (down 82 bp). This
downward trend in yields was reflective of a change in the earning asset
mix and general interest rate declines during 2002 and into 2003, as
evident in residential real estate loans (121 bp decline in yield),
indirect consumer loans (115 bp decline) and commercial loans (44 bp
decline). As a result, the loan portfolio yield decreased 63 bp. The
investment portfolio yield also declined 84 bp, the net result of
declines in U.S. Treasury securities (down 175 bp), mortgage backed
securities and collateralized mortgage obligations (down 178 bp), U.S.
Agency obligations (down 121 bp) and municipal securities (down 55 bp).

Comparing the first nine months of 2003 to 2002, interest and fee income
(FTE) decreased by $7.3 million (3.8%). The decline was due to the net
effect of a higher volume of earning assets and the impact of lower
yields. The positive volume component was the result of a $288.9 million
(7.8%) increase in average earning assets, including mortgage backed
securities and collateralized mortgage obligations (up $247.6 million ),
U.S. Agency obligations (up $204.0 million), municipal securities (up
$125.0 million), indirect consumer loans (up $27.1 million) and
residential real estate loans (up $8.7 million). The following
components decreased: U.S. Treasury securities (down $109.9 million),
other securities (down $84.0 million), commercial real estate loans
(down $72.7 million), commercial loans (down $24.5 million),
construction loans (down $16.7 million) and direct consumer loans (down
$14.9 million).

The average yield on earning assets for the first nine months of 2003
was 6.15% compared to 6.89% in 2002. Major decreases in loan yields were
a 117 bp decline in residential real estate loans, a 34 bp decline in
the yield on commercial loans and a 106 bp decrease in the yield on
consumer loans. As a result, the composite loan yield declined 70 bp.
The investment portfolio yield decreased 81 bp, affected primarily by
lower yields on U.S. Treasury securities (down 152 bp), mortgage backed
securities and collateralized mortgage obligations (down 148 bp), U.S.
Agency obligations (down 126 bp) and municipal securities (down 40 bp).


Interest Expense

Interest expense decreased $3.7 million (37.1%) in the third quarter of
2003 compared to the same year-ago period. The decrease resulted from a
drop in the average rate paid on interest-bearing liabilities from 1.48%
in 2002 to 0.89% in 2003. The average rate on short-term borrowings
dropped 56 bp, rates on CDs over $100 thousand declined an average of
102 bp, rates on retail CDs declined 80 bp, and rates on money market
savings accounts were lowered 59 bp.

The effect of a $133.2 million (5.0%) increase in average
interest-bearing liabilities in the third quarter caused an increase in
volume-related expense and partially offset the above-mentioned
rate-related decline in interest expense. Short-term borrowings rose by
$111.3 million whereas Federal Home Loan Bank ("FHLB") advances
decreased by $42.4 million. Interest-bearing deposits rose by $67.7
million, the net result of increases in money market savings (up $95.4
million), CDs over $100 thousand (up $51.7 million) money market
checking (up $32.5 million) and regular savings (up $18.8 million),
partially reduced by decreases in preferred money market savings (down
$94.0 million) and retail CDs (down $33.9 million).

Page 14

During the first nine months of 2003, interest expense decreased $9.2
million (30.1%) from 2002, again due to a lower average rate paid on
interest-bearing liabilities (1.03% in 2003 compared with 1.58% in the
same period in 2002). All deposit categories declined including money
market savings (from 1.40% in the first nine months of 2002 to 0.80% in
the same period of 2003), CDs over $100 thousand (from 2.41% to 1.42%)
and retail CDs with maturities varying from one month to over three
years (from 2.56% to 1.75%). Interest rates on short-term borrowings
declined from 1.53% to 0.93%.

Interest-bearing liabilities grew $186.2 million or 7.2% for the nine
months ended September 30, 2003 and caused a volume-related increase in
interest expense, which partially offset the rate-related decline in
interest expense. Increases in money market savings (up $101.8 million),
money market checking (up $31.7 million), short-term borrowings (up
$120.0 million) and FHLB advances (up $26.5 million) were partially
offset by declines in preferred money market savings (down $75.8
million) and retail CDs (down $30.3 million).

In all periods, the Company has continuously attempted to reduce
high-rate time deposits while increasing the balances of more
profitable, lower-cost transaction accounts in order to minimize the
effect of adverse cyclical trends.


Net Interest Margin (FTE)

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

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


During the third quarter of 2003, the net interest margin fell 40 bp
compared to the same period in 2002. Yields on earning assets declined
faster than rates paid on interest-bearing liabilities, resulting in a
23 bp decline in net interest spread. The unfavorable impact of lower
rates earned on loans and the investment portfolio, triggered by market
trends, were partially mitigated by decreases in rates paid on deposits
and short-term funds. The decline in the net interest spread was further
widened by the lower value of noninterest-bearing funding sources. While
the average balance of these sources increased $77.3 million or 10.1%,
their value decreased 17 bp because of the lower market rates of
interest at which they could be invested.

Similarly, on a year-to-date basis, the net interest margin decreased 35
bp when compared to the same period in 2002. Earning asset yields
decreased 74 bp and the cost of interest-bearing liabilities fell by 55
bp, resulting in a 19 bp decline in the interest spread.
Noninterest-bearing funding sources increased $68.6 million or 9.5% and
because of lower market rates of interest their margin contribution
decreased by 16 bp, with their value decreasing to 32 bp.

Summary of Average Balances, Yields/Rates and Interest Differential

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

(1) Net interest spread represents the average yield earned on earning assets
    minus the average rate paid on interest-bearing liabilities.

(2) Net interest margin is computed by calculating the difference between
    interest income and expense, divided by the average balance of earning
    assets.

Provision for Loan Losses

The level of the provision for loan losses during each of the periods presented
reflects the Company's continued efforts to reduce credit costs by enforcing
underwriting and administration procedures and aggressively pursuing collection
efforts with troubled debtors. The Company provided $750 thousand for
loan losses in the third quarter of 2003 and $900 thousand in the same
quarter of 2002. For the first nine months of 2003, $2.6 million was
provided while in 2002, $2.7 million was provided. The lower provision
reflects management's assessment of credit risk in the loan portfolio.
Additionally, $2.1 million of reserves were acquired in connection with
the KSB acquisition in the second quarter of 2002. For further
information regarding net credit losses and the allowance for loan
losses, see the "Classified Loans" section of this report.

Noninterest income for the third quarter of 2003 was $11.0 million, up
$558 thousand or 5.3% compared with the same quarter of 2002. During
this period $2.2 million securities gains were recorded and $2.2 million
in prepayment fees were paid to retire $65 million of FHLB advances. The
largest factor contributing to higher income was service charges on
deposits (up $441 thousand) mainly resulting from a new debit card
overdraft program introduced in January of 2003. The second largest
factor was a $178 thousand increase in other noninterest income largely
due to higher income from foreclosed property sales and letter-of-credit
fees, partially offset by lower income earned on outstanding official
checks and interest recoveries from charged-off loans. Mortgage banking
income declined $118 thousand due to less refinancing activity and lower
gains on loan sales.

Noninterest income for the nine months of 2003 was $32.4 million, up
$6.1 million or 23.1% from 2002, mainly due to the 2002 securities
impairment charge and growth in fee income. In 2003 $2.4 million in
gains on sale of securities were recorded, partially offsetting the $2.2
million prepayment penalty paid to reduce FHLB advances by $65 million.
Similar to the quarter-to-quarter comparison, service charges on
deposits represent the largest increase. (up $1.5 million) due to a new
debit card overdraft program. Another factor was a $276 thousand growth
in debit card fees due to increased usage offset by lower debit card
processing rates. Other noninterest income was $142 thousand more than
the previous year due to gains on asset sales and higher
letter-of-credit fees, partly reduced by lower official check income and
interest recoveries on charged-off loans. Decreases in noninterest
income included a $382 thousand decline in financial services
commissions due to lower sales of fixed annuities, mutual funds and life
insurance.

Noninterest expense for the third quarter of 2003 was $25.5 million,
$430 thousand or 1.7% lower than in 2002. The largest decline was in
salaries and related benefits, which were down $349 thousand (2.5%),
primarily due to a $297 thousand decrease in salaries as a result of a
decline in the number of full-time equivalent employees and lower
performance-related incentives. Higher costs of workers compensation (up
$155 thousand) partially offset the decline. Equipment expense fell $160
thousand compared with 2002 mostly due to lower depreciation.
Amortization of deposit intangibles declined $136 thousand primarily due
to the expiration of the deposit intangible in connection with a 1996
acquisition. Other noninterest expense increased $166 thousand largely
due to increases in charges from the Company's two main correspondent
banks.

Noninterest expense was $76.5 million for the nine months of 2003, which
was $1.0 million or 1.3% less than 2002. The largest decrease was
salaries and related benefits (down $1.2 million or 2.9%) as a result of
declines in salaries (down $878 thousand) due to a fewer number of
full-time equivalent employees and lower incentives (down $489
thousand). Additionally, the 2002 period included $366 thousand
severance pay relating to the KSB acquisition. A $264 thousand increase
in workers compensation expense reduced the effect of savings in
salaries and other benefits. Equipment expense fell by $265 thousand
from 2002 primarily due to lower depreciation. Advertising and public
relations expense fell by $125 thousand primarily due to lower spending
on marketing research and overall business development. Amortization of
deposit intangibles declined $124 thousand largely due to the expiration
of the deposit intangibles from a prior acquisition. Other discretionary
spendings fell including a $112 thousand decline in stationery and
supplies expense. Other noninterest expense rose $441 thousand largely
due to the combined effect of a $172 thousand increase in low-income
housing operating losses, a $139 thousand increase in charges from the
Company's two main correspondent banks, and a $125 thousand decline in
settlement expense. Occupancy expense rose $213 thousand mainly due to a
$120 thousand increase in utilities and increases in insurance and
property taxes. Telephone expense rose $110 thousand mostly due to
installation of new data lines.


Provision for Income Tax

During the third quarter of 2003, the Company recorded income tax
expense of $9.3 million, $1.9 million (17.2%) lower than the third
quarter of 2002; on a year-to-date basis, the income tax provision was
$29.8 million for 2003 compared to $30.1 million for 2002. The current
quarter provision represents an effective tax rate of 27.9%, compared to
33.0% for the third quarter of 2002; for the first nine months of 2003,
the effective tax rate was 29.7%, compared to 32.0% recorded in 2002.
The provision for income taxes for all periods presented is primarily
attributable to the respective level of earnings and the incidence of
allowable deductions, in particular higher revenues recognized from
state and municipal securities and tax credits generated from low-income
housing investments, and for California franchise taxes, higher
excludable interest income on loans within enterprise zones.

Classified Loans

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

The following is a summary of classified loans and repossessed
collateral on the dates indicated (dollars in thousands):

Classified loans at September 30, 2003, decreased $10.3 million (30.4%)
from September 30, 2002, reflecting the effectiveness of the Company's
high underwriting standards and active workout policies. Repossessed
collateral increased $272 thousand or 57.9% from September 30, 2002, due
to five new foreclosures on loans totaling $1.5 million, partially
offset by sales, principal reductions and writedowns of properties
acquired in satisfaction of debt. A $10.5 million (30.9%) decrease in
classified loans from December 31, 2002, was due to payoffs, upgrades,
chargeoffs and transfers to repossessed collateral, partly offset by new
downgrades. The $361 thousand (94.8%) increase in repossessed collateral
from December 31, 2002, was primarily due to five new foreclosures
valued at $1.5 million, partially offset by sales, principal reductions
and writedowns of foreclosed properties.


Nonperforming Loans

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

Performing nonaccrual loans at September 30, 2003 fell $1.7 million
(44.2%) from the same period in the previous year and $1.3 million
(38.1%) from December 31, 2002. The decrease from both periods was due
to payoffs, chargeoffs, loans being returned to accrual status and loans
being placed on nonperforming nonaccrual, offset by new loans placed on
performing nonaccrual.

Nonperforming nonaccrual loans at September 30, 2003 decreased $343
thousand (5.9%) from the same period a year ago and $233 thousand (4.1%)
from year-end, 2002. The decreases resulted from loans being returned to
full-accrual status, transfers to repossessed collateral or being
charged off or paid off, partially offset by loans being added to
nonperforming nonaccrual.

Changes in repossessed collateral are discussed above.

The Company had no restructured loans as of September 30, 2003, 2002 and
December 31, 2002.

The amount of gross interest income that would have been recorded for
nonaccrual loans for the three and nine month periods ended September
30, 2003, if all such loans had performed in accordance with their
original terms, was $110 thousand and $415 thousand, respectively,
compared to $183 thousand and $445 thousand, respectively, for the third
quarter and the first nine months of 2002.

The amount of interest income that was recognized on nonaccrual loans
from all cash payments, including those related to interest owed from
prior years, made during the three and nine months ended September 30,
2003, totaled $299 thousand and $516 thousand, respectively, compared to
$50 thousand and $376 thousand, respectively, for the comparable periods
in 2002. These cash payments represent annualized yields of 17.36% and
8.77%, respectively, for the third quarter and the first nine months of
2003 compared to 2.15% and 6.28%, respectively, for the third quarter
and the first nine months of 2002.

Total cash payments received during the third quarter of 2003 which were
applied against the book balance of nonaccrual loans outstanding at
September 30, 2003, totaled zero, compared with approximately $85
thousand in 2002. Cash payments received totaled $283 thousand for the
nine months ended September 30, 2003, compared with approximately $211
thousand for 2002.

The overall credit quality of the loan portfolio continues to be strong;
however, total nonperforming assets could fluctuate from period to
period. The performance of any individual loan can be impacted by
external factors such as the interest rate environment or factors
particular to the borrower. The Company expects to maintain the level of
nonperforming assets; however, the Company can give no assurance that
additional increases in nonaccrual loans will not occur in the future.


Allowance for Loan Losses

The Company's allowance for loan losses is maintained at a level
considered adequate to provide for losses that can be estimated based
upon specific and general conditions. These include conditions unique to
individual borrowers, as well as overall credit loss experience, the
amount of past due, nonperforming and classified loans, recommendations
of regulatory authorities, prevailing economic conditions and other
factors.

Page 25

A portion of the allowance is specifically allocated to impaired and
other identified loans whose full collectibility is uncertain. Such
allocations are determined by Management based on loan-by-loan analyses.
A second allocation is based in part on quantitative analyses of
historical credit loss experience, in which criticized and classified
loan balances are analyzed using a linear regression model to determine
standard allocation percentages. The results of this analysis are
applied to current criticized and classified loan balances to allocate
the reserve to the respective segments of the loan portfolio. In
addition, loans with similar characteristics not usually criticized
using regulatory guidelines are analyzed based on the historical rate of
net losses and delinquency trends, grouped by the number of days the
payments on these loans are delinquent. Last, allocations are made to
general loan categories based on relevant economic conditions and
available data, including unemployment statistics, commercial office
vacancy rates, mortgage loan foreclosure trends, agriculture commodity
prices, and levels of government funding.

Management considers the $54.2 million allowance for loan losses, which
constituted 2.29% of total loans at September 30, 2003, to be adequate
as a reserve against inherent losses. However, while the Company's
policy is to charge off in the current period those loans on which the
loss is considered probable, the risk exists of future losses which
cannot be precisely quantified or attributed to particular loans or
classes of loans. Management continues to evaluate the loan portfolio
and assess current economic conditions that will dictate future required
allowance levels.

The following table summarizes the loan loss provision, net credit losses and
allowance for loan losses for the periods indicated (dollars in thousands):

Asset and Liability Management

The fundamental objective of the Company's management of assets and
liabilities is to maximize economic value while maintaining adequate
liquidity and a conservative level of interest rate risk. The Company
actively solicits loans and transaction deposit accounts. Asset and
liability management techniques include adjusting the duration,
liquidity, volume, rates and yields, and other attributes of its loan
products, investment portfolio, time deposits, and other funding sources
to achieve Company objectives.

The primary analytical tool used by the Company to gauge interest rate
risk is a simulation model to project changes in net interest income
("NII") that result from forecast changes in interest rates. The
analysis calculates the difference between a NII forecast over a
12-month period using a flat interest rate scenario, and a NII forecast
using a rising rate scenario where the Fed Funds rate is made to rise
evenly by 100 bp and 200 bp, and a falling rate scenario of 50 bp over
the 12-month forecast interval triggering a response in the other
forecasted rates. Company policy requires that such simulated changes in
NII should be within certain specified ranges or steps must be taken to
reduce interest rate risk. The results of the model indicate that the
mix of interest rate sensitive assets and liabilities at September 30,
2003 would not result in a fluctuation of NII that would exceed the
parameters established by Company policy.


Liquidity

The Company's principal source of asset liquidity is marketable
investment securities available for sale. At September 30, 2003,
investment securities available for sale totaled $1.2 billion,

Page 26

representing an increase of $242 million from September 30, 2002. In
addition, at September 30, 2003, the Company had customary lines for
overnight borrowings from other financial institutions in excess of $500
million and a $20 million line of credit, under which no amount was
outstanding at September 30, 2003. Additionally, as a member of the
Federal Reserve System, the Company has the ability to borrow from the
Federal Reserve. The Company may also borrow from the FHLB which it
collateralizes with its residential real estate loans and securities. At
September 30, 2003, the Company had excess collateral providing
available borrowing capacity from the FHLB of approximately $138 million.

Since January 1, 2000, the Company has reduced its long-term debt by
$31.9 million, reducing its debt-to-equity ratio from 14% at January 1,
2000 to 3% at September 30, 2003. The Company's long-term debt rating
from Fitch Ratings was raised from A- to A, with a stable outlook, in
June 2003. On October 31, 2003, the Company issued in a private
placement a $15 million senior note at a fixed rate of 5.31% over a
ten-year term. The note is due in full on October 31, 2013. Management
is confident the Company could access additional long-term debt
financing if desired.

In addition, the Company generates significant liquidity from its
operating activities. The Company's profitability during the first nine
months of 2003 and 2002 generated substantial cash flows, which are
included in the totals provided from operations of $87.6 million and
$74.9 million, respectively. The operating cash flow in 2003 was more
than sufficient to pay for $24.4 million in shareholder dividends and
$43.9 million of stock repurchases. In 2002, the operating activities
provided a substantial portion of cash for $22.2 million in shareholder
dividends and $53.9 million for the Company's stock repurchase programs.

During the first nine months of 2003, other financing activities
included the net result of a $242.1 million increase in deposits and
$83.6 million proceeds from short-term borrowings, reduced by a $67.2
million payment of FHLB advances and prepayment fees. During the first
three quarters of 2002, other financing activities included $74.4
million proceeds from short-term borrowings and $130.0 million from FHLB
advances, reduced by a $32.3 million decrease in deposits.

The Company had net cash outflows in its investing activities during
both nine month periods ended September 30. In 2003, purchases net of
sales and maturities of investment securities were $426.9 million, which
was in part offset by net repayments of loans of $125.5 million. The
investment securities portfolio increase was generally financed by a
$242.1 million increase in deposits, and a $83.6 million increase in
short-term borrowings.

During the first nine months of 2002 the Company had net cash outflows
in its investing activities. Purchases net of sales and maturities of
investment securities of $216.3 million were reduced by net repayments
of loans of $32.7 million and $5.4 million cash obtained in the KSB
acquisition, resulting in net cash used of $178.8 million. At September
30, 2002, investment securities available for sale totaled $1,003.2
million, representing an increase of $54.2 million from December 31, 2001.


Capital Resources

The current and projected capital position of the Company and the impact
of capital plans and long-term strategies is reviewed regularly by
Management. The Company repurchases shares of its common stock in the
open market with the intention of lessening the dilutive impact of
issuing new shares to meet stock performance, option plans, and other
ongoing requirements. In addition, other programs have been implemented
to optimize the Company's use of equity capital and enhance shareholder
value. Pursuant to these programs, the Company repurchased 1.0 million
and 1.3 million shares during the first nine months of 2003 and 2002,
respectively.

The Company's primary capital resource is shareholders' equity, which
was $350.9 million at September 30, 2003. This amount represents an
increase of $9.4 million (2.8%) from December 31, 2002, the net result
of the issuance of stock ($10.1 million) and comprehensive income for
the period ($67.6 million), partially offset by share repurchases ($43.9
million) and dividends paid ($24.4 million). Due to the net effect of an
increase in equity capital combined with earning asset growth the
Company's ratio of equity to total assets declined slightly to 7.83% at
September 30, 2003, from 7.97% a year ago. The equity to assets ratio
was 8.08% at December 31, 2002.

Page 27

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


                                                   At
                                    At September 30,    December 31  Minimum

                                  ---------------------------------------------
                                                             
Tier I Capital                         10.35%      9.47%      9.71%      4.00%
Total Capital                          11.61%     10.73%     10.97%      8.00%
Leverage ratio                          7.14%      7.12%      7.27%      4.00%



The risk-based capital ratio increased at September 30, 2003, compared
to the prior year primarily due to an increase in shareholders' equity
as a result of increased net income, partially offset by the Company's
common stock repurchases and dividends paid to shareholders. Also, a
decline in risk-weighted assets contributed to this improvement. The
risk-based capital ratio increased at September 30, 2003 from December
31, 2002 primarily due to the combination of an increase in
shareholders' equity as a result of increased net income and a reduction
in risk-weighted assets.


New Accounting Pronouncements

In January 2003, the Financial Accounting Standards Board ("FASB")
issued FASB Interpretation 46 ("FIN 46"), which clarifies the
application of Accounting Research Bulletin ("ARB") 51, consolidated
financial statements, to certain entities (called variable interest
entities) in which equity investors do not have the characteristics of a
controlling financial interest or do not have sufficient equity at risk
for the entity to finance its activities without additional subordinated
financial support from other parties. The consolidation requirements of
the standard apply to all variable interest entities created after
January 31, 2003. In addition, for variable interest entities that
existed prior to February 1, 2003 and remain in existence, a recent FASB
staff position on FIN 46 indicates that public companies must apply the
consolidation requirements as of the end of the first interim or annual
period ending after December 15, 2003. Given the nature of the Company's
operations, management does not expect this Interpretation to have a
significant impact on the consolidated financial statements.

In April 2003, the FASB issued Statement No.149, Amendment of Statement
133 on Derivative Instruments and Hedging Activities, to provide
clarification of certain terms and investment characteristics identified
in Statement 133. Statement 149 is to be applied prospectively and is
effective for contracts entered into or modified after June 30, 2003.
The adoption of the Statement did not have a material impact on the
consolidated financial statements.

In May 2003, the FASB issued Statement No.150, Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and
Equity. The provisions of this Statement are generally effective for
financial instruments entered into or modified after May 31, 2003, and
otherwise are generally effective at the beginning of the first interim
period beginning after June 15, 2003, except for mandatorily redeemable
financial instruments of nonpublic entities. Given the nature of the
Company's liability and equity instruments, adoption of this Statement
did not have a material impact on the consolidated financial statements
upon adoption of the Statement on July 1, 2003.


Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company does not currently engage in trading activities or use derivative
instruments to control interest rate risk, even though such activities may be
permitted with the approval of the Company's Board of Directors.

Interest rate risk as discussed above is the most significant market risk
affecting the Company. Other types of market risk, such as foreign currency
exchange risk, equity price risk and commodity price risk, are not significant
in the normal course of the Company's business activities.


Item 4. Controls and Procedures

The Company's principal executive officer and principal financial officer have
evaluated the effectiveness of the Company's "disclosure controls and
procedures," as such term is defined in Rule 13a-14(c) of the Securities
Exchange Act of 1934, as amended, as of September 30, 2003. Based upon
their evaluation, the principal executive officer and principal
financial officer concluded that the Company's disclosure controls and
procedures are effective. There were no significant changes in the
Company's internal controls or in other factors that could significantly
affect these controls, since the date the controls were evaluated.
