amended. Forward-looking statements are not guarantees of future performance and
involve risks, uncertainties, and other factors which may cause future
performance to vary from expected performance summarized in the forward-looking
statements, including those set forth in this paragraph. Important factors that
could cause our actual results, performance, or achievements to be materially
different from any future results, performance, or achievements expressed or
implied by those statements include, but are not limited to: the failure to

to attract additional qualified personnel, the loss of key customers, increased
competition, the inability to remain current with rapid technological change,
risks related to acquisitions, risks associated with business cycles and
fluctuations in interest rates, utility and system interruptions or processing
errors, rules and regulations governing financial institutions and changes in
such rules and regulations, credit risk related to borrowers' ability to repay
loans, concentration of loans to certain segments such as commercial
enterprises, churches and borrowers in the St. Louis area which creates risks

                 CASS INFORMATION SYSTEMS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

Note 1 - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with U.S. generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by U.S. generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the period ended June 30, 2004 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2004. For further information, refer to the consolidated financial
statements and related footnotes included in the Cass Information System, Inc.'s
("the Company") Annual Report on Form 10-K for the year ended December 31, 2003.

Certain amounts in the 2003 consolidated financial statements have been
reclassified to conform to the 2004 presentation. Such reclassifications have no
effect on previously reported net income or shareholders' equity. All share and
per share data for 2003 has been restated to reflect the 10% stock dividend
issued in March 2004.

Note 2 - Impact of New Accounting Pronouncements

In December 2003, the FASB issued Interpretation No. 46 (revised December 2003),
"Consolidation of Variable Interest Entities" (FIN 46R), which addresses how a
business enterprise should evaluate whether it has controlling financial
interest in an entity through means other than voting rights and accordingly
should consolidate the entity. FIN 46R replaces FIN 46, "Consolidation of
Variable Interest Entities, an interpretation of Accounting Research Bulletin
No. 51," issued in January 2003. Companies are required to apply FIN 46R to
variable interest entities (VIEs) created after December 31, 2003. For variable
interest in VIEs created before January 1, 2004, FIN 46R will be applied
beginning on January 1, 2005. The Company is currently not a primary beneficiary
of a VIE and therefore the adoption of FIN 46R did not have a material impact on
its consolidated financial statements.

In December 2003, the FASB issued SFAS 132 (Revised 2003), "Employers'
Disclosures about Pensions and Other Postretirement Benefits," which increases
the disclosure requirements of the original statement by requiring more details
about pension plan assets, benefit obligations, cash flows, benefit costs and
related information and also requires companies to disclose various elements of
pension and postretirement benefit costs in interim-period financial statements
for quarters beginning after December 15, 2003. Additional disclosures
pertaining to benefit payments are required for fiscal years ending after June
30, 2004. The disclosure requirements of SFAS 132 (Revised 2003) are included in
Note 11 of this report.

ended June 30, 2004 and repurchased 59,237 shares for $1,764,000 during the
first six months ended June 30, 2003. Repurchases are made in the open market or

Note 6 - Industry Segment Information

The services provided by the Company are classified into four reportable
segments: Transportation Information Services, Utility Information Services,
Banking Services and Government Software Services. Each of these segments
provides distinct services that are marketed through different channels. They
are managed separately due to their unique service, processing and capital
requirements.

The Transportation Information Services segment provides freight invoice rating,
payment, auditing, cost accounting and transportation information services to
large corporate shippers. The Utility Information Services segment processes and
pays utility invoices, including electricity, gas, water and telecommunications,
for large corporate entities that have many locations or are heavy users of
energy. The Banking Services segment provides banking services primarily to
privately-held businesses and churches. The Government Software Services segment
provides the public sector with integrated financial, property and human
resource management systems through the Bank's wholly-owned subsidiary,
Government e-Management Solutions, Inc. (GEMS).

The Company's accounting policies for segments are the same as those described
in the summary of significant accounting policies in the Company's Annual Report
on Form 10-K for the year ended December 31, 2003. Management evaluates segment
performance based on net income after allocations for corporate expenses and
income taxes. Transactions between segments are accounted for at what management
believes to be fair value.

All four segments market their services within the United States and no revenue
from any customer of any segment exceeds 10% of the Company's consolidated
revenue.

Summarized information about the Company's operations in each industry segment
for the three and six month periods ended June 30, 2004 and 2003, is as follows:

Note 7 - Intangible Assets

The Company accounts for intangible assets in accordance with SFAS 142,
"Goodwill and Other Intangible Assets," which requires that intangibles with
indefinite useful lives be tested annually for impairment and those with finite
useful lives be amortized over their useful lives. Intangible assets for the
periods ended June 30, 2004 and December 31, 2003 are as follows:



                                                June 30, 2004                 December 31, 2003

*Amortization through December 31, 2001 prior to adoption of SFAS 142.

Customer list and software are amortized over 15 years and 4 years,
respectively. The minimum pension liability was recorded in accordance with SFAS
87, "Employers' Accounting for Pensions", which requires the Company to record
an additional minimum pension liability by the amount of which the accumulated
benefit obligation exceeds the sum of the fair value of plan assets and accrued
amount previously recorded and offset this liability by an intangible asset to
the extent of previously unrecognized prior service costs. The liability and
corresponding intangible asset are adjusted annually.


                                      -8-


Amortization of intangible assets amounted to $77,000 for both the three-month
periods ended June 30, 2004 and 2003 and $155,000 for both the six-month periods
ended June 30, 2004 and 2003. Estimated amortization of intangibles over the
next five years is as follows: $311,000 in 2004, 2005 and 2006 and $55,000 in
2007 and 2008.

Note 8 - Equity Investments in Non-Marketable Securities

During 2003, the Company converted a $2,000,000 investment in a private imaging
company from a convertible debenture into common stock. As part of the
conversion, the Company committed to invest an additional $1,100,000 if certain
conditions were met. The total investment of the Company in this entity was
$3,100,000 at June 30, 2004 and $2,908,000 at December 31, 2003. At June 30,
2004 the Company had a 19.93% ownership interest in this entity and the Chairman
and CEO of the Company was a member of the entity's Board of Directors. In
addition, the Company has committed to a $2,400,000 line of credit to this
entity, with a 50% interest sold to the new majority owner, for working capital
purposes. As of June 30, 2004 the Company's interest in this line amounted to
$933,000.

This business has performed poorly during the past few years and during 2003
received an additional $3,000,000 equity investment from the new non-affiliated
majority owner, in addition to the Company's additional commitment. The new
majority owner is currently in the process of stabilizing the business and
improving its financial performance. Operations have recently become profitable.
However, should this business fail to meet its objectives, the Company's
investment could be subject to future impairment.

This investment, along with $543,000 of other investments in non-marketable
securities, is included in other assets on the Company's consolidated balance
sheets.

Note 9 - Commitments and Contingencies

In the normal course of business, the Company is party to activities that
contain credit, market and operational risk that are not reflected in whole or
in part in the Company's consolidated financial statements. Such activities
include traditional off-balance sheet credit-related financial instruments and
commitments under operating leases. These financial instruments include
commitments to extend credit, commercial letters of credit and standby letters
of credit. The Company's maximum potential exposure to credit loss in the event
of nonperformance by the other party to the financial instrument for commitments
to extend credit, commercial letters of credit and standby letters of credit is
represented by the contractual amounts of those instruments. At June 30, 2004,
no amounts have been accrued for any estimated losses for these instruments.

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commercial
and standby letters of credit are conditional commitments issued by the Company
or its subsidiaries to guarantee the performance of a customer to a third party.
These off-balance sheet financial instruments generally have fixed expiration
dates or other termination clauses and may require payment of a fee. The
approximate remaining term of commercial and standby letters of credit range
from less than 1 to 3 years. Since some of the financial instruments may expire
without being drawn upon, the total amounts do not necessarily represent future
cash requirements. Commitments to extend credit and letters of credit are
subject to the same underwriting standards as those financial instruments
included on the consolidated balance sheets. The Company evaluates each
customer's credit worthiness on a case-by-case basis. The amount of collateral
obtained, if deemed necessary upon extension of the credit, is based on
management's credit evaluation of the borrower. Collateral held varies, but is
generally accounts receivable, inventory, residential or income-producing
commercial property or equipment. In the event of nonperformance, the Company or
its subsidiaries may obtain and liquidate the collateral to recover amounts paid
under its guarantees on these financial instruments.

Summarized credit-related financial instruments, including both commitments to
extend credit and letters of credit and operating lease commitments at June 30,
2004 are as follows:

                                    Amount of Commitment Expiration per Period
                                    ------------------------------------------

The Company and its subsidiaries are involved in various pending legal actions
and proceedings in which claims for damages are asserted. Management, after
discussion with legal counsel, believes the ultimate resolution of these legal
actions and proceedings will not have a material effect upon the Company's
consolidated financial position or results of operations.

Note 10 - Stock-Based Compensation

The Company maintains two stock-based compensation plans, a stock bonus plan and
a stock option plan. Upon issuance of shares in the stock bonus plan a contra
shareholders' equity amount is recorded for the fair value of the shares at the
time of issuance and this amount is amortized to expense over the three-year
vesting period. The stock option plan is accounted for under APB 25, "Accounting
for Stock Issued to Employees", and accordingly the Company recognizes no
compensation expense as the price of the Company's employee stock options equals
the market price of the underlying stock on the date of grant. The Company
elected not to adopt the recognition provisions of SFAS 123, "Accounting for
Stock-Based Compensation", as amended by SFAS 148. An entity that continues to
apply APB 25 shall disclose certain pro forma information as if the fair
value-based accounting method in SFAS 123 had been used to account for
stock-based compensation costs. The required disclosure provisions of SFAS 123,
as amended by SFAS 148, are provided in the table below. The Company uses the
Black-Scholes option-pricing model to determine the fair value of the stock
options at the date of grant. There were 2,759 and 3,543 options granted in the
Second Quarter of 2004 and 2003, respectively. For the First Half of 2004 and
2003 there were 8,630 and 15,543 options granted, respectively. The following
table represents the effect on basic and diluted earnings per share and weighted
average assumptions used for the periods ended June 30, 2004 and 2003:

Note 11 - Defined Pension Plans

The Company has a noncontributory defined benefit pension plan, which covers
most of its employees. The Company accrues and makes contributions designed to
fund normal service costs on a current basis using the projected unit credit
with service proration method to amortize prior service costs arising from
improvements in pension benefits and qualifying service prior to the
establishment of the plan over a period of approximately 30 years. Disclosure
information is based on a measurement date of December 31 of the corresponding
year.

Pension costs recorded to expense were $365,000 and $237,000 for the Second
Quarter of 2004 and 2003, respectively. Pension costs recorded to expense were
$625,000 and $474,000 for the First Half of 2004 and 2003, respectively. The
Company has not made any contribution to the plan during the six-month period
ended June 30, 2004, but is expecting to contribute approximately $1,083,000 in
2004.

In addition to the above funded benefit plan, the Company has an unfunded
supplemental executive retirement plan which covers key executives of the
Company. This is a noncontributory plan in which the Company and its
subsidiaries make accruals designed to fund normal service costs on a current
basis using the same method and criteria as its defined benefit plan.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

Overview

Cass Information Systems, Inc. provides payment and information processing
services to national manufacturing, distribution and retail enterprises from its
processing centers in St. Louis, Missouri, Columbus, Ohio, and Boston,
Massachusetts. The Company's services include freight invoice rating, payment
processing, auditing, and the generation of cost accounting and transportation
information. Cass also processes and pays utility invoices, including
electricity, gas and telecommunications. Cass extracts, stores and presents
information from freight and utility invoices, assisting our customers'
transportation and energy managers in making decisions that will enable them to
improve their operating performance. The Company receives data from multiple
sources, electronic and otherwise, and processes the data to accomplish the
specific operating requirements of its customers. It then provides the data in a
central repository for access and archiving. The data is finally transformed
into information through the Company's databases that allow client interaction
with the data and provide Internet-based tools for analytical processing. The
Company also, through its St. Louis, Missouri based bank subsidiary, provides
banking services in the St. Louis metropolitan area and other selected cities in
the United States. In addition to supporting the Company's payment operations,
it also provides banking services to its target markets, which include privately
owned businesses and churches. The Company, through the Bank's subsidiary,
Government e-Management Solutions, Inc. (GEMS), also develops and licenses
integrated financial, property and human resource management systems to the
public sector.

The specific payment and information processing services provided to each
customer are developed individually to meet each customer's specific
requirements. These requirements can vary greatly from customer to customer. In
addition, the degree of automation such as electronic data interchange (EDI),
imaging, and web-enhanced solutions varies greatly among customers and
industries. These factors combine so that pricing varies greatly among the
customer base. In general however, Cass is compensated for its processing
services through service fees and account balances that are generated during the
payment process. The amount, type and calculation of service fees vary greatly


                                      -11-


by service offering, but generally follow the volume of transactions processed.
Interest income from the balances generated during the payment processing cycle
is affected by the amount of time Cass holds the funds prior to payment and the
dollar volume processed. Both the number of transactions processed and the
dollar volume processed are therefore key metrics followed by management. Other
factors have a significant influence on revenue and profitability however, such
as changes in the general level of interest rates which has a significant affect
on net interest income. The funds generated by these processing activities are
invested in overnight investments, investment grade securities and loans
generated by the Bank. The Bank earns most of its revenue from net interest
income, or the difference between the interest earned on its loans and
investments and the interest expense on its deposits. The Bank also assesses
fees on other services such as cash management services. GEMS earns its revenue
from the license of its enterprise software solutions and fees for its
installation and maintenance.

Industry-wide factors that impact the Company include the acceptance by large
corporations of the outsourcing of key business functions such as freight and
utility payment. The benefits that can be achieved by outsourcing transaction
processing and the management information generated by Cass' systems can be
influenced by factors such as the competitive pressures within industries to
improve profitability, the general level of transportation costs and the
deregulation of energy costs. Economic factors that impact the Company include
the general level of economic activity that can affect the volume and size of
invoices processed, the ability to hire and retain qualified staff and the
growth and quality of our loan portfolio. The general level of interest rates
has a significant affect on the revenue of the Company. Finally, the general
fiscal condition of the counties and municipalities that can benefit from GEMS'
enterprise software can impact licenses sold and related revenue.

Currently, management views Cass' major opportunity and challenge as the
continued expansion of its payment and information processing service offerings
and customer base. Management intends to accomplish this by maintaining Cass'
lead in applied technology, which, when combined with the security and
processing controls of the Company's Bank, makes Cass unique in the industry.
This trend has been positive over the past years and management anticipates that
this should continue during 2004 and beyond. In addition, management is
exploring possible strategic alliances and potential acquisitions to accelerate
this growth. In July 2004, the Company announced that it had reached an
agreement to acquire the operating assets and selected liabilities of ProfitLab,
Inc. ProfitLab is a leading provider of telecom auditing and application
services. This acquisition should further strengthen and expand Cass' payment
and data analysis services and tools for Fortune 1000 customers. The acquisition
is expected to close in the third quarter of 2004. Should the acquisition close,
the initial impact on the Company's earnings would be negative. Based on recent
performance the annualized, after tax, loss of ProfitLab is anticipated to be in
the area of $500,000 to $650,000 or $.13 to $.17 diluted earnings per share.
While benefits are expected to occur from integrating certain operational areas,
it may take some time before such benefits are achieved. As part of the
acquisition, Cass has agreed to provide employment for certain staff members and
to maintain operations in Greenville, South Carolina for periods of two and
three years, respectively.

The low level of interest rates has had a significant negative impact on net
income during the past few years. Although management doesn't anticipate when
and how quickly these rates may increase, the Company is positioned to take
advantage of rising rates should they occur. Management had been pleased with
the growth in software revenue generated by GEMS during the last three years,
but is disappointed with software sales this year. It appears that lack of
activity in the marketplace has negatively impacted sales but active interest,
as measured by the number of requests for proposals received, seems to be
improving.

Critical Accounting Policies

The Company has prepared all of the consolidated financial information in this
report in accordance with U.S. generally accepted accounting principles (U.S.
GAAP). In preparing the consolidated financial statements in accordance with
U.S. GAAP, management makes estimates and assumptions that affect the reported
amount of assets and liabilities, disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
revenue and expenses during the reporting period. These estimates have been
generally accurate in the past, they have been consistent and have not required
any material changes. There can be no assurances that actual results will not
differ from those estimates. Certain accounting policies that require
significant management estimates and are deemed critical to our results of
operations or financial position have been discussed with the Audit Committee of
the Board of Directors and are described below.


                                      -12-


Allowance for Loan Losses. The Company performs periodic and systematic detailed
reviews of its loan portfolio to assess overall collectability. The level of the
allowance for loan losses reflects management's estimate of the collectability
of the loan portfolio. Although these estimates are based on established
methodologies for determining allowance requirements, actual results can differ
significantly from estimated results. These policies affect all segments of the
Company with the exception of governmental software services. The impact and
associated risks related to these policies on our business operations are
discussed in the " Allowance and Provision for Loan Losses" section of this
report.

Impairment of Assets. Management periodically evaluates certain long-term assets
such as intangible assets including goodwill, foreclosed assets, internally
developed software and investments in private equity securities for impairment.
Generally, these assets are initially recorded at cost, and recognition of
impairment is required when events and circumstances indicate that the carrying
amounts of these assets will not be recoverable in the future. If impairment
occurs, various methods of measuring impairment may be called for depending on
the circumstances and type of asset, including quoted market prices, estimates
based on similar assets, and estimates based on valuation techniques such as
discounted projected cash flows. Assets held for sale are carried at the lower
of cost or fair value less costs to sell. These policies affect all segments of
the Company and require significant management assumptions and estimates that
could result in materially different results if conditions or underlying
circumstances change.

Results of Operations

The following paragraphs more fully discuss the results of operations and
changes in financial condition for the three-month period ended June 30, 2004
(the "Second Quarter of 2004") compared to the three-month period ended June 30,
2003 (the "Second Quarter of 2003") and the six-month period ended June 30, 2004
(the "First Half of 2004") compared to the six-month period ended June 30, 2003
(the "First Half of 2003"). The following discussion and analysis should be read
in conjunction with the consolidated financial statements and related notes and
with the statistical information and financial data appearing in this report as
well as the Company's 2003 Annual Report on Form 10-K. Results of operations for
the Second Quarter of 2004 are not necessarily indicative of the results to be
attained for any other period.

Net Income

The Company's net income was $1,700,000 for the Second Quarter of 2004, a
$539,000 or 24.1% decrease compared to net income of $2,239,000 for the Second
Quarter of 2003. The Company's net income for the First Half of 2004 was
$3,547,000, a $210,000 or 5.6% decrease compared to net income of $3,757,000 for
the First Half of 2003. Diluted earnings per share were $.45 for the Second
Quarter of 2004, a 25.0% decrease compared to $.60 for the Second Quarter of
2003. Diluted earnings per share were $.95 for the First Half of 2004, a 5.9%
decrease compared with $1.01 for the First Half of 2003. The decrease in net
income in the Second Quarter of 2004 over the Second Quarter of 2003 was
primarily a result of gains on the sales of equity securities recognized in the
Second Quarter of 2003 with no gains recognized in the Second Quarter of 2004,
compounded by a decrease in software revenue recorded by the Company's software
subsidiary, GEMS. This was partially offset by an increase in payment and
processing revenue and a decrease in operating expenses. The decrease in net
income in the First Half of 2004 was the result of more gains recognized in the
First Half of 2003 compared with the First Half of 2004 and a decrease in
software revenue, offset by increased revenue from payment and processing fees
and a decrease in operating expenses. Return on average assets for the Second
Quarter of 2004 was .99% compared to 1.51% for the Second Quarter of 2003.
Return on average assets for the First Half of 2004 was 1.06% compared to 1.28%
for the First Half of 2003. Return on average equity for the Second Quarter of
2004 was 10.60% compared to 14.74% for the Second Quarter of 2003. Return on
average equity for the First Half of 2004 was 11.06% compared to 12.45% for the
First Half of 2003.


                                      -13-


Fee Revenue and Other Income

Fee revenue is principally derived from freight and utility payment and
processing fees. Processing volumes related to these fees for the three and
six-month periods ended June 30, 2004 and 2003 are as follows:



                                                  Three Months Ended                   Six Months Ended

Transportation Information Services:
   Invoice Bill Volume                       5,921         5,810     1.9%        11,350        11,476    (1.1%)
   Invoice Dollar Volume                $2,416,168    $2,154,256    12.2%    $4,637,814    $4,208,168    10.2%

Utility Information Services:
   Invoice Transaction Volume                1,286         1,116    15.2%         2,570         2,149    19.6%
   Invoice Dollar Volume                $  895,730    $  788,714    13.6%    $1,830,091    $1,614,075    13.4%
   Payment and processing fees          $    2,572    $    2,200    16.9%    $    5,224    $    4,200    24.4%


Second Quarter of 2004 compared to Second Quarter of 2003:

Transaction volume from the Transportation Information Services division for the
Second Quarter of 2004 increased mainly due to increased activity from existing
clients which more than offset the loss of some high transaction/low dollar
volume parcel business. Total dollar volume processed from this division
increased during this period. Fees for the period grew due to the increased
volume and additional services provided. The increase in volume and fees from
the Utility Information Services division increased primarily due to new
customers as the growth of this segment continues. Software revenue was down
$720,000 or 39% from the Second Quarter of 2003 primarily due to reduced license
fee revenue generated from new customers. Although revenue generated by GEMS
increased in each of the past three years, sales were off significantly this
year to date. Demand for software in the governmental sector appears to have
softened from last year. At this time management feels that this is a temporary
condition. Bank service fees decreased $35,000 or 8% due to the decrease in
miscellaneous services provided to other banks. Net gains of $1,362,000 were
recognized on the sales of securities during the Second Quarter of 2003 with no
gains recognized in the Second Quarter of 2004. Other income increased $41,000
or 30% primarily due to income recognized from death proceeds from company owned
life insurance.

First Half of 2004 compared to First Half of 2003:

Transportation transaction volume for the First Half of 2004 decreased slightly
from 2003 due to the same loss of high transaction/low dollar parcel business
mentioned above. Most of this volume was replaced by larger dollar transactions
that required a higher level of processing and produced greater fees.
Transaction dollar volume was up and fee revenue increased during the first
half. Utility volume and fees increased due to new customers as this segment
continues to grow. Software revenue from GEMS was down $1,337,000 or 37% during
the First Half of 2004 due to the same factors discussed above for the second
quarter. Bank service fees decreased $47,000 or 5% due to the decrease in
miscellaneous services provided to other banks. Gains on the sales of securities
for the First Half of 2004 were $441,000 compared to gains of $1,362,000 for the
First Half of 2003. Other income increased $47,000 or 18% due to the death
proceeds from company owned life insurance.

Net Interest Income

Second Quarter of 2004 compared to Second Quarter of 2003:

The Company's tax-equivalent net interest income increased 1% or $49,000 from
$6,700,000 to $6,749,000. The tax-equivalent net interest margin decreased from
5.02% to 4.33%. The decline in the general level of interest rates from the
beginning of 2001 continues to have a negative impact on the Company's net
interest income and margin. The average yield on earning assets decreased to
4.80% in the Second Quarter of 2004 from 5.36% in 2003. The Company is
negatively affected by decreases in the level of interest rates due to the fact
that its rate sensitive assets significantly exceed its rate sensitive
liabilities. Conversely, the Company is positively affected by increases in the
level of interest rates. This is primarily due to the noninterest-bearing
liabilities generated by the Company in the form of accounts and drafts payable.
Changes in interest rates will affect some earning assets such as federal funds
sold and floating rate loans immediately and some earning assets, such as fixed
rate loans and municipal bonds, over time.


                                      -14-


The Company was able to offset the decrease in net interest income due to the
decline in the general level of interest rates through an increase in earning
assets. Total average earning assets increased $92,643,000 or 17% to
$627,453,000. This increase was funded by both an increase in accounts and
drafts payable due to the increase in dollar volume processed and an increase in
bank deposits due to the expansion of the Banks' customer base.

Total average loans increased $31,840,000 or 7% to $467,292,000. This increase
was attributable to new business relationships and was funded by the increase in
accounts and drafts payable and growth in bank deposits. Although not enough to
offset the decline in the level of interest rates, this increase in loans had a
positive effect on interest income and the net interest margin due to the fact
that loans are one of the Company's highest yielding earning assets for any
given maturity.

Total average investment in debt and equity securities increased $18,531,000 or
34% to $73,170,000. Total average federal funds sold and other short-term
investments increased $42,272,000 or 95% to $86,991,000. This increase provides
additional liquidity and positions the Company to take advantage of higher
interest rates should they occur. For more information on the changes in net
interest income please refer to the tables on the pages that follow.

First Half of 2004 compared to First Half of 2003:

The Company's tax-equivalent net interest income decreased $64,000 from
$13,639,000 to $13,575,000. The tax-equivalent net interest margin decreased
from 5.15% to 4.45% as the decline in the general level of interest rates from
the beginning of 2001 continues to have an impact on the Company's net interest
income and margin. The average yield on earning assets decreased to 4.88% in the
First Half of 2004 from 5.49% in 2003.

The Company partially offset the decrease in net interest income through an
increase in earning assets. Total average earning assets increased $78,774,000
or 15% to $613,338,000. This increase was funded by both an increase in accounts
and drafts payable due to the increase in dollars processed and an increase in
bank deposits due to the expansion of the Banks' customer base.

Total average loans increased $30,595,000 or 7% to $465,375,000. This increase
was attributable to new business relationships and was funded by the increase in
accounts and drafts payable and growth in bank deposits. Although not enough to
offset the decline in the level of interest rates, this increase in loans had a
positive effect on interest income and the net interest margin due to the fact
that loans are one of the Company's highest yielding earning assets for any
given maturity.

Total average investment in debt and equity securities increased $8,544,000 or
14% to $68,904,000. Total average federal funds sold and other short-term
investments increased $39,635,000 or 101% to $79,059,000. This increase provides
additional liquidity and positions the Company to take advantage of higher
interest rates should they occur. For more information on the changes in net
interest income please refer to the tables on the pages that follow.

1.    Balances shown are daily averages.
2.    For purposes of these computations, nonaccrual loans are included in the
      average loan amounts outstanding. Interest on nonaccrual loans is recorded
      when received as discussed further in Note 1 to the Company's 2003
      Consolidated Financial Statements.
3.    Interest income on loans includes net loan fees of $49,000 and $24,000 for
      the Second Quarter of 2004 and 2003, respectively.
4.    Interest income is presented on a tax-equivalent basis assuming a tax rate
      of 34%. The tax-equivalent adjustment was approximately $275,000 and
      $215,000 for the Second Quarter of 2004 and 2003, respectively.
5.    For purposes of these computations, yields on investment securities are
      computed as interest income divided by the average amortized cost of the
      investments.

                     Analysis of Net Interest Income Changes

The following table presents the changes in interest income and expense between
periods due to changes in volume and interest rates. That portion of the change
in interest attributable to the combined rate/volume variance has been allocated
to rate and volume changes in proportion to the absolute dollar amounts of the
change in each.

Allowance and Provision for Loan Losses

A significant determinant of the Company's operating results is the provision
for loan losses and the level of loans charged off. There was a $150,000
provision made for loan losses during the Second Quarter of 2004 and no
provision made in the Second Quarter of 2003. There was a $350,000 provision
made for the First Half of 2004 compared with a $90,000 provision for the First
Half of 2003. Net loans recovered for both the Second Quarter of 2004 and 2003
were $6,000. Net loans recovered for the First Half of 2004 were $9,000 compared
to $10,000 for the First Half of 2003. The provision for loan losses can vary
over time based on an ongoing assessment of the adequacy of the allowance for
loan losses.

The allowance for loan losses at June 30, 2004 was $5,865,000 and at December
31, 2003 was $5,506,000. The ratio of allowance for loan losses to total loans
outstanding at June 30, 2004 was 1.24% compared to 1.17% at December 31, 2003.
Nonperforming loans were $3,467,000 or .73% of total loans at June 30, 2004
compared to $4,393,000 or .94% of total loans at December 31, 2003. The decrease
from December 31, 2003 is primarily due to two loans; one for $481,000 that was
renegotiated in First Quarter of 2003 and is now current under the new terms of
the agreement and a second loan for $376,000 that was foreclosed in the First
Quarter of 2004 and is now being carried as other real estate owned.

At June 30, 2004, impaired loans totaled $3,627,000, which included $1,057,000
of nonaccrual loans and $2,410,000 of renegotiated loans compared with impaired
loans at December 31, 2003 of $4,393,000, which included $1,525,000 of
nonaccrual loans and $2,721,000 of renegotiated loans. The allowance for loan
losses on impaired loans was $960,000 at June 30, 2004 and there were no
impaired loans without an allowance. The decrease in impaired loans from
December 31, 2003 relates primarily to the decrease in nonperforming loans as
explained in the previous paragraph.

Total impaired loans decreased $2,330,000 from June 30, 2003 to June 30, 2004.
Of this decrease $4,070,000 relates to other impaired loans consisting primarily
of two loans totaling $4,229,000 at June 30, 2003 that were renegotiated in 2002
and are now currently performing. This decrease was partially offset by an
increase of $1,929,000 in renegotiated loans, which relates primarily to one
borrower with a balance of $2,240,000 as of June 30, 2004 and although currently
performing, is still considered impaired by management. The balance of
nonaccrual loans at June 30, 2004 consists primarily of two loans, one with a
balance of $713,000 that is collateralized by real estate and has a SBA
guarantee and a second loan with a balance of $265,000 relates to a business
that is no longer operating, although payments are being made as the inventory
of the business is being sold.

The allowance for loan losses has been established and is maintained to absorb
losses inherent in the loan portfolio. An ongoing assessment of risk of loss is
performed to determine if the current balance of the allowance is adequate to
cover probable losses in the portfolio. A charge or credit is made to expense to
cover any deficiency or reduce any excess. The current methodology employed to
determine the appropriate allowance consists of two components, specific and
general. The Company develops specific valuation allowances on commercial,
commercial real estate, and construction loans based on individual review of
these loans and our estimate of the borrower's ability to repay the loan given
the availability of collateral, other sources of cash flow and collection
options available to us. The general component relates to all other loans, which
are evaluated based on loan grade. The loan grade assigned to each loan is
typically evaluated on an annual basis, unless circumstances require interim
evaluation. The Company assigns a reserve amount consistent with each loan's
rating category. The reserve amount is based on derived loss experience over
prescribed periods. In addition to the amounts derived from the loan grades, a
portion is added to the general reserve to take into account other factors
including national and local economic conditions, downturns in specific
industries including loss in collateral value, trends in credit quality at the
Company and the banking industry, and trends in risk rating changes. As part of
their examination process, federal and state agencies review the Company's
methodology for maintaining the allowance for loan losses and the balance in the
account. These agencies may require the Company to increase the allowance for
loan losses based on their judgments and interpretations about information
available to them at the time of their examination.

The Bank currently has two properties which it is carrying as other real estate
owned at what management believes to be fair value less cost to sell. The first
property was foreclosed on August 8, 2001 and is recorded at $859,000 and the
second property was foreclosed on March 2, 2004 and is recorded at $375,000.

Operating Expense

Total operating expense for the Second Quarter of 2004 decreased $583,000 or 4%
to $13,313,000 compared to the Second Quarter of 2003. Total operating expense
for the First Half of 2004 decreased $896,000 or 3% to $26,795,000 from the
First Half of 2003.

Salaries and benefits expense decreased $99,000 or 1% to $9,301,000 in the
Second Quarter of 2004 compared with the Second Quarter of 2003 and decreased
$294,000 or 2% for the First Half of 2004 compared with the First Half of 2003.
These decreases are primarily related to a reduction in the number of employees
attributable to a series of technology initiatives put into place by the
Information Services divisions. The decrease in salaries expense was partially
offset by annual salary increases and an increase in benefits expense related to
pension costs.

Occupancy expense for the Second Quarter of 2004 decreased $21,000 or 5% to
$436,000 from the Second Quarter of 2003 and increased a modest $1,000 in the
First Half of 2004 compared with the First Half of 2003. The decrease for the
quarter relates primarily to a decrease in utility expense and premise
maintenance and repairs.

Equipment expense for the Second Quarter of 2004 decreased $135,000 or 12%
compared to the Second Quarter of 2003 and decreased $271,000 or 12% for the
First Half of 2004 compared with the First Half of 2003. These decreases relate
primarily to a decrease in software amortization in both the Information
Services divisions and a decrease in hardware depreciation and computer
equipment maintenance expense from the consolidation of equipment within the
Transportation Information Services division.

Other operating expense for the Second Quarter of 2004 decreased $328,000 or 11%
compared to the Second Quarter of 2003 and decreased $332,000 or 6% for the
First Half of 2004 compared with the First Half of 2003. The decreases for the
quarter and half were primarily from decreases in postage and supply expense in


                                      -20-


the Transportation Information Services division related to technology
initiatives put into place over the past two years. These decreases were offset
by an increase in outsourced programming services primarily in the Company's
government software division.

Income tax expense for the Second Quarter of 2004 decreased $364,000 or 35%
compared to the Second Quarter of 2003 and decreased $149,000 or 9% for the
First Half of 2004 compared with the First Half of 2003. The effective tax rate
for the Second Quarter of 2004 was 28% compared with 32% in the Second Quarter
of 2003 and was 29% for the First Half of 2004 compared with 30% in 2003. The
decrease in the effective tax rate was due to higher balances of tax-exempt
investments in 2004.

Financial Condition

Total assets at June 30, 2004 increased $48,466,000 or 8% from December 31,
2003. The majority of this increase relates to the Company's earning assets that
experienced an increase of $18,482,000 or 41% in federal funds sold and other
short-term investments, $18,189,000 or 26% increase in investments in debt and
equity securities and $5,169,000 or 1% increase in loans, net of the allowance
for loan losses.

Total liabilities were $622,326,000, an increase of $47,422,000 or 8% from
December 31, 2003. Total deposits at June 30, 2004 were $297,700,000, an
increase of $25,272,000 or 9%. Accounts and drafts payable were $315,773,000, an
increase of $22,004,000 or 7%. Total shareholders' equity at June 30, 2004 was
$65,836,000 a $1,044,000 or 2% increase from December 31, 2003.

The increase in loans relates to the normal fluctuations of the loan portfolio.
The increase in debt and equity securities relates to the purchase of
$41,247,000 in securities, primarily of tax-exempt municipal securities. These
purchases were partially offset by the sale of securities earlier in the year
and the normal maturity of securities throughout the year. Federal funds sold
and other short-term investments increased due to the increase in deposits and
accounts and drafts payable from December 31, 2003 to June 30, 2004. The
increase in deposits reflects the Bank's ongoing marketing efforts to attract
deposits and increase in accounts and drafts payable was due the increase in the
dollar volume of invoices processed. Accounts and drafts payable will fluctuate
from period-end to period-end due to the payment processing cycle, which results
in lower balances on days when checks clear and higher balances on days when
checks are issued. For this reason, average balances are a more meaningful
measure of accounts and drafts payable. The increase in total shareholders'
equity resulted from net income of $3,547,000; cash received on the exercise of
stock options of $151,000; a $99,000 tax benefit on stock awards and the
amortization of the stock bonus plan of $45,000; offset by dividends paid of
$1,476,000 ($.42 per share); a decrease in other comprehensive income of
$1,318,000 and $4,000 of cash paid for stock dividend fractional shares.

Liquidity and Capital Resources

The balances of liquid assets consists of cash and cash equivalents, which
include cash and due from banks, federal funds sold and money market funds, and
were $85,089,000 at June 30, 2004, an increase of $22,722,000 or 36% from
December 31, 2003. At June 30, 2004 these assets represented 12% of total
assets. These funds are the Company's and its subsidiaries' primary source of
liquidity to meet future expected and unexpected loan demand, depositor
withdrawals or reductions in accounts and drafts payable.

Secondary sources of liquidity include the investment portfolio and borrowing
lines. Total investment in debt and equity securities was $87,336,000 at June
30, 2004, an increase of $18,189,000 from December 31, 2003. These assets
represented 13% of total assets at June 30, 2004. Of this total, 69% were state
and political subdivision securities, 23% were U.S. Treasury securities, 7% were
U.S. government agencies and 1% were other securities. Of the total portfolio,
19% mature in one year, 14% matures in one to five years, and 67% matures in
five or more years. During the year the Company sold securities with a market
value of $12,052,000 and a portion of these funds were reinvested in U.S.
Treasury and agency securities.

The Bank has unsecured lines at correspondent banks to purchase federal funds up
to a maximum of $29,000,000. Additionally, the Bank maintains a line of credit
at an unaffiliated financial institution in the maximum amount of $85,418,000
collateralized by securities sold under repurchase agreements.

The deposits of the Company's banking subsidiary have historically been stable,
consisting of a sizable volume of core deposits related to customers that
utilize many other commercial products of the Bank. The accounts and drafts
payable generated by the Company has also historically been a stable source of
funds.

Net cash flows provided by operating activities were $3,516,000 for the First
Half of 2004 compared with $7,040,000 for the First Half of 2003. This decrease
is attributable to an additional $1,963,000 paid in corporate income taxes, a
$100,000 decrease in deferred income versus a $1,796,000 increase in the First
Half of 2003 and other normal fluctuations in other asset and liability
accounts. Net cash flows from investing and financing activities fluctuate
greatly as the Company actively manages its investment and loan portfolios and
customer activity influences changes in deposit and accounts and drafts payable
balances. Further analysis of the changes in these account balances is discussed
earlier in this report. Due to the daily fluctuations in these account balances,
the analysis of changes in average balances, also discussed earlier in this
report, can be more indicative of underlying activity than the period-end
balances used in the statements of cash flows. Management anticipates that cash
and cash equivalents, maturing investments and cash from operations will
continue to be sufficient to fund the Company's operations and capital
expenditures in 2004.

The Company faces market risk to the extent that its net interest income and
fair market value of equity are affected by changes in market interest rates.
For information regarding the market risk of the Company's financial
instruments, see Item 3. "QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK".

Risk-based capital guidelines require the Company to meet a minimum total
capital ratio of 8.0% of which at least 4.0% must consist of Tier 1 capital.
Tier 1 capital generally consists of (a) common shareholders' equity (excluding
the unrealized market value adjustments on the available-for-sale securities),
(b) qualifying perpetual preferred stock and related surplus subject to certain
limitations specified by the FDIC, (c) minority interests in the equity accounts
of consolidated subsidiaries less (d) goodwill, (e) mortgage servicing rights
within certain limits, and (f) any other intangible assets and investments in
subsidiaries that the FDIC determines should be deducted from Tier 1 capital.
The FDIC also requires a minimum leverage ratio of 3.0%, defined as the ratio of
Tier 1 capital less purchased mortgage servicing rights to total assets, for
banking organizations deemed the strongest and most highly rated by banking
regulators. A higher minimum leverage ratio is required of less highly rated
banking organizations. Total capital, a measure of capital adequacy, includes
Tier 1 capital, allowance for loan losses, and debt considered equity for
regulatory capital purposes.

The Company and the Bank continue to exceed all regulatory capital requirements,
as evidenced by the following capital amounts and ratios at June 30, 2004 and
December 31, 2003:

Inflation

The Company's assets and liabilities are primarily monetary, consisting of cash,
cash equivalents, securities, loans, payables and deposits. Monetary assets and
liabilities are those that can be converted into a fixed number of dollars. The
Company's consolidated balance sheet reflects a net positive monetary position
(monetary assets exceed monetary liabilities). During periods of inflation, the
holding of a net positive monetary position will result in an overall decline in
the purchasing power of a company. Management believes that replacement costs of
equipment, furniture, and leasehold improvements will not materially affect
operations. The rate of inflation does affect certain expenses, such as those
for employee compensation, which may not be readily recoverable in the price of
the Company's services.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As described in the Company's Annual Report on Form 10-K for the year ended
December 31, 2003, the Company manages its interest rate risk through
measurement techniques that include gap analysis and a simulation model. As part
of the risk management process, asset/liability management policies are
established and monitored by management. The policy objective is to limit the
change in annualized net interest income to 15% from an immediate and sustained
parallel change in interest rates of 200 basis points. Based on the Company's
most recent evaluation, management does not believe the Company's risk position
at June 30, 2004 has changed materially from that at December 31, 2003.

ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures designed to ensure that
the information it is required to disclose in the reports it files with the SEC
is recorded, processed, summarized and reported to management, including the
Chief Executive Officer and Principal Financial Officer, within the time periods
specified in the rules of the SEC. The Company's Chief Executive and Principal
Financial Officers have reviewed and evaluated the Company's disclosure controls
and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange
Act) as of June 30, 2004 and based on their evaluation believe that these
procedures are effective to ensure that the Company is able to collect, process
and disclose the information it is required to disclose in the reports it files
with the SEC within the required time periods.

There were no changes in the second quarter of 2004 in the Company's internal
controls identified by the Chief Executive and Principal Financial Officers in
connection with their evaluation that materially affected or are reasonably
likely to materially affect the Company's internal controls over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

        The Company and its subsidiaries are not involved in any pending
        proceedings other than ordinary routine litigation incidental to their
        businesses. Management believes none of these proceedings, if determined
        adversely, would have a material effect on the business or financial
        condition of the Company or its subsidiaries.

        shares for $1,764,000 during the first six months ended June 30, 2003.
