Inc. ("Company") for interim financial reporting are consistent with the

NOTE 2 - STOCK COMPENSATION

Employee compensation expense under stock options is reported using the
intrinsic value method. No stock-based compensation cost is reflected in net
income, as all options granted had an exercise price equal to or greater than
the market price of the underlying common stock at date of grant. The following
table illustrates the effect on net income and earnings per share if expense was
measured using the fair value recognition provisions of FASB Statement No. 123,
Accounting for Stock-Based Compensation.

Results of Operations

Net income for the first quarter of 2004 was $3,635 or 3.7% greater than the
first quarter of 2003. Earnings per share for the first quarter equaled $.34 in
2004, compared to $.33 in 2003, an increase of 3.0%. The Company's return on
average total assets for the first quarter was 1.03% in 2004 and 1.15% in 2003.
Return on average shareholders' equity for the first quarter was 13.60% in 2004
and 14.19% in 2003.

Net Interest Income

The volume and yield of earning assets and interest-bearing liabilities
influence net interest income. Net interest income reflects the mix of interest-
bearing and non-interest-bearing liabilities that fund earning assets, as well
as interest spreads between the rates earned on these assets and the rates paid
on interest-bearing liabilities. First quarter net interest income of $11,472 in
2004 was an increase of 7.1% versus the first quarter of 2003. Net interest
income on a tax equivalent basis, reflected as a percentage of average earning
assets (net interest margin), was 3.68% for the first quarter of 2004 and 3.90%
for the same timeframe in 2003. As a result of the current interest rate
environment, the Company's yield on earning assets on a tax equivalent basis
decreased from 6.04% in the first quarter of 2003 to 5.34% in the first quarter
of 2004. The Company's cost of funds also decreased, but to a lesser extent.

Provision for Loan Losses

This topic is discussed under the heading "Loans, Credit Risk and the Allowance
and Provision for Probable Loan Losses".

Non-interest Income

First quarter non-interest income for 2004 was $4,764, relatively unchanged
versus the first quarter of 2003. The impact of the acquisition of First
Community in the second quarter of 2003, an increase in insurance commissions
and the implementation of a formalized overdraft program were offset by
decreases in mortgage banking activity and investment securities gains. Mortgage
banking income, which consists of gains and losses on loan sales and service fee
income, was $799 for the first quarter of 2004 versus $1,353 for the first
quarter of 2003.

               (Dollar amounts in thousands except per share data)

Non-interest expense

Total non-interest expense was $11,081 for the first quarter of 2004, which
represented an increase of $769 from the first quarter of 2003. The increase was
primarily due to the acquisition of First Community, which added $1,495 of
non-interest expense in 2004. Offsetting this increase was a decrease in the
amortization of deferred debt acquisition costs. In the first quarter of 2003,
the Company redeemed a portion of its subordinated debentures and wrote-off
approximately $850 in related costs. The largest component of non-interest
expense is personnel expense. Personnel expenses were $6,441 for the first
quarter of 2004 versus $5,514 for the same period a year ago, representing a
16.8% increase. Excluding the acquisition of First Community, employee costs for
the first quarter of 2004 would have been $5,719, an increase of 5.1%, and would
be attributable to normal staff salary increases.

Income Taxes

The effective tax rate for the first three months was 29.5% for 2004 which was
relatively stable compared to 27.9% for 2003. The Company and its subsidiaries
file consolidated income tax returns.

               (Dollar amounts in thousands except per share data)

Financial Condition

Total assets at March 31, 2004 were $1,416,180 compared to $1,442,729 as of
December 31, 2003. Average earning assets represented 90.5% of average total
assets for the first three months of 2004 and 91.7% for the same period in 2003.
Average loans represented 73.9% of average deposits in the first three months of
2004 and 72.1% for the comparable period in 2003. Management continues to
emphasize quality loan growth to increase these averages. Average loans as a
percent of average assets were 60.1% and 59.8% for the three-month period ended
March 31, 2004 and 2003 respectively.

The decrease in deposits of $43,352 from December 31, 2003 to March 31, 2004 was
due primarily to the loss of public fund deposits which are generally temporary
and seasonal in nature.

Shareholders' equity was $108,563 on March 31, 2004 compared to $105,424 on
December 31, 2003. Book value (shareholders' equity) per common share was $10.26
at March 31, 2004 versus $9.94 at year-end 2003. Accumulated other comprehensive
income increased book value per share by $.23 at March 31, 2004 and by $.12 at
December 31, 2003. Depending on market conditions, the unrealized gain or loss
on securities available for sale can cause fluctuations in shareholders equity.

Loans, Credit Risk and the Allowance and Provision for Probable Loan Losses

Loans remain the Company's largest concentration of assets and, by their nature,
carry a higher degree of risk. The loan underwriting standards observed by the
Company's subsidiaries are viewed by management as a means of controlling
problem loans and the resulting charge-offs.

The Company's loan underwriting standards have historically resulted in lower
levels of net charge-offs than peer bank averages. The Company believes credit
risks may be elevated if undue concentrations of loans in specific industry
segments and to out-of-area borrowers are incurred. Accordingly, the Company's
Board of Directors regularly monitors such concentrations to determine
compliance with its loan allocation policy. The Company believes it has no undue
concentrations of loans.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
               (Dollar amounts in thousands except per share data)

Residential real estate loans continue to represent a significant portion of the
total loan portfolio. Such loans represented 36.8% of total loans at March 31,
2004 and 36.9% at December 31, 2003.

On March 31, 2004, the Company had $5,925 of residential real estate loans held
for sale, which was an increase from the year-end balance of $1,965. The Company
generally retains the servicing rights on mortgages sold.

Asset quality deteriorated from a year ago with non-performing assets totaling
$16.1 million, or 1.13% of total assets, as of March 31, 2004 compared to $11.8
million, or 0.94% of total assets, as of the same period a year ago. This amount
represents a decrease from year-end 2003 of $1.2 million, or 7% of total
non-performing assets. With the acquisition of First Community, the Company
added approximately $4.4 million of non-performing assets. Management believes
that adequate allowance allocations have been provided for these loans as of
March 31, 2004. The allowance for loan losses was $11.3 million as of March 31,
2004 and represented 1.35% of total outstanding loans.

The provision for loan losses was $0 in the first quarter of 2004 compared to
$390 for the same period in 2003. The provision for 2004 was lower than 2003 as
non-performing loan balances declined from year-end and several credits were
upgraded to a more favorable risk rating. Additionally, net charge-offs totaled
$176 in the first quarter of 2004 compared to $432 in the last quarter of 2003.

The adequacy of the allowance for loan losses in each subsidiary is reviewed at
least quarterly. The determination of the provision amount in any period is
based on management's continuing review and evaluation of loan loss experience,
changes in the composition of the loan portfolio, current economic conditions,
the amount of loans presently outstanding, and information about specific
borrower situations. The allowance for loan losses as of March 31, 2004 was
considered adequate by management.

Investment Securities

Investment securities offer flexibility in the Company's management of interest
rate risk, and are an important source of liquidity as a response to changing
characteristics of assets and

               (Dollar amounts in thousands except per share data)

liabilities. The Company's investment policy prohibits trading activities and
does not allow investment in high-risk derivative products, junk bonds or
foreign investments.

As of March 31, 2004, $418,475 of investment securities are classified as
"available for sale" ("AFS") and are carried at fair value with unrealized gains
and losses, net of taxes, reported as a separate component of shareholders'
equity. An unrealized pre-tax gain of $4,293 was recorded to adjust the AFS
portfolio to current market value at March 31, 2004, compared to an unrealized
pre-tax gain of $2,185 at December 31, 2003.

Sources of Funds

The Company relies primarily on customer deposits, securities sold under
agreement to repurchase ("agreements") and shareholders' equity to fund earning
assets. FHLB advances are also used to provide additional funding.

Deposits generated within local markets provide the major source of funding for
earning assets. Average total deposits funded 89.8% and 90.5% of total average
earning assets for the periods ending March 31, 2004 and 2003. Total
interest-bearing deposits averaged 89.9% and 90.5% of average total deposits for
the periods ending March 31, 2004 and 2003, respectively. Management constantly
strives to increase the percentage of transaction-related deposits to total
deposits due to the positive effect on earnings.

The Company had FHLB advances of $56,786 outstanding at March 31, 2004. These
advances have interest rates ranging from 4.4% to 6.7% with $10,000 maturing in
the second quarter of 2005. The remaining amount of FHLB advances mature in 2007
or later.

Capital Resources

Total shareholders' equity was $108,563 at March 31, 2004, which was an increase
from $105,424 at December 31, 2003. The increase in equity was attributable to
the increase in the unrealized gain on investment securities and the earnings
for the first quarter. Offsetting these items were cash dividends paid on common
stock and treasury stock purchases.

The Federal Reserve Board and other regulatory agencies have adopted risk-based
capital guidelines that assign risk weightings to assets and off-balance sheet
items. The Company's core capital consists of shareholders' equity, excluding
accumulated other comprehensive income, while Tier 1 consists of core capital
less goodwill and intangibles. Trust preferred securities qualify as Tier 1
capital or core capital with respect to the Company under the risk-based capital
guidelines established by the Federal Reserve. Under such guidelines, capital
received from the proceeds of the sale of trust preferred securities cannot
constitute more than 25% of the total core capital of the Company. Consequently,
the amount of trust preferred securities in excess of the 25% limitation
constitutes Tier 2 capital of the Company. Total regulatory capital consists of
Tier 1, certain debt instruments and a portion of the allowance for loan
losses. At March 31, 2004, Tier 1 capital to total average assets was 6.24%.
Tier 1

               (Dollar amounts in thousands except per share data)

capital to risk-adjusted assets was 9.70%. Total capital to risk-adjusted assets
was 11.79%. All three ratios exceed all required ratios established for bank
holding companies. Risk-adjusted capital levels of the Company's subsidiary
banks exceed regulatory definitions of well-capitalized institutions.

The Company declared and paid common dividends of $.120 per share in the first
quarter of 2004 versus $.114 for the first quarter of 2003.

Liquidity

Liquidity management involves maintaining sufficient cash levels to fund
operations and to meet the requirements of borrowers, depositors, and creditors.
Higher levels of liquidity bear higher corresponding costs, measured in terms of
lower yields on short-term, more liquid earning assets, and higher interest
expense involved in extending liability maturities. Liquid assets include cash
and cash equivalents, loans and securities maturing within one year, and money
market instruments. In addition, the Company holds AFS securities maturing after
one year, which can be sold to meet liquidity needs.

Maintaining a relatively stable funding base, which is achieved by diversifying
funding sources and extending the contractual maturity of liabilities, supports
liquidity and limits reliance on volatile short-term purchased funds. Short-term
funding needs arise from declines in deposits or other funding sources, funding
of loan commitments and requests for new loans. The Company's strategy is to
fund assets to the maximum extent possible with core deposits that provide a
sizable source of relatively stable and low-cost funds. Average core deposits
funded approximately 78.9% of total earning assets for the three months ended
March 31, 2004 and 82.0% for the same period in 2003.

Management believes the Company has sufficient liquidity to meet all reasonable
borrower, depositor, and creditor needs in the present economic environment. In
addition, the affiliates have access to the Federal Home Loan Bank for borrowing
purposes. The Company has not received any recommendations from regulatory
authorities that would materially affect liquidity, capital resources or
operations.

Interest Rate Risk

Asset/liability management strategies are developed by the Company to manage
market risk. Market risk is the risk of loss in financial instruments including
investments, loans, deposits and borrowings arising from adverse changes in
prices/rates. Interest rate risk is the Company's primary market risk exposure,
and represents the sensitivity of earnings to changes in market interest rates.
Strategies are developed that impact asset/liability committee activities based
on interest rate risk sensitivity, board policy limits, desired sensitivity gaps
and interest rate trends.

Effective asset/liability management requires the maintenance of a proper ratio
between maturing or repriceable interest-earning assets and interest-bearing
liabilities. It is the policy of the Company that the cumulative GAP divided by
total assets shall be plus or minus 20% at the 3-month, 6-month, and 1-year time
horizons.

At March 31, 2004, the Company held approximately $480 million in assets
comprised of securities, loans, short-term investments, and federal funds sold,
which were interest sensitive in one year or less time horizons.

Item 4.  Controls and Procedures

As of the end of the quarterly period covered by this report, an evaluation was
carried out under the supervision and with the participation of the Company's
management, including our Chief Executive Officer and Chief Financial Officer,
of the effectiveness of our disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14(c) under the Securities Exchange Act of 1934). Based
on their evaluation, our Chief Executive Officer and Chief Financial Officer
have concluded that the Company's disclosure controls and procedures were, to

Act is recorded, processed, summarized and reported within the time periods
specified in Securities and Exchange Commission rules and forms as of such date.

There was no change in the Company's internal control over financial reporting
that occurred during the Company's first fiscal quarter of 2004 that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
