Note 3 - Equity Investments in Non-Marketable Securities

Non-marketable equity investments in low-income housing projects are included in
other assets on the Company's consolidated balance sheets. The total balance of
these investments at December 31, 2007 and June 30, 2008 was $475,000 and
$440,000, respectively.

Note 4 - Earnings Per Share

Basic earnings per share is computed by dividing net income by the
weighted-average number of common shares outstanding. Diluted earnings per share
is computed by dividing net income, adjusted for the net income effect of the
interest expense on the outstanding convertible debentures, by the sum of the
weighted-average number of common shares outstanding and the weighted-average
number of potential common shares outstanding. The calculations of basic and
diluted earnings per share for the periods ended June 30, 2008 and 2007 are as
follows:

Note 7 - Industry Segment Information

The services provided by the Company are classified into two reportable
segments: Information Services and Banking 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 Information Services segment provides freight, utility and telecommunication
invoice processing and payment services to large corporations. The Banking
Services segment provides banking services primarily to privately-held
businesses and churches.

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, 2007. 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 market value.

All revenue originates from and all long-lived assets are located 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, 2008 and 2007, is as follows:

Note 9 - Commitments and Contingencies

In the normal course of business, the Company is party to activities that
contain credit, market and operational risks 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 and capital 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
December 31, 2007 and June 30, 2008, 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. At December
31, 2007 the balance of unused loan commitments, standby and commercial letters
of credit were $29,036,000, $5,999,000 and $4,147,000, respectively. At June 30,
2008 the balance of unused loan commitments, standby and commercial letters of
credit were $22,880,000, $6,777,000 and $3,621,000, respectively. 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 balances 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.

The following table summarizes contractual cash obligations of the Company
related to operating lease commitments, time deposits and convertible
subordinated debentures at June 30, 2008:

* Includes principal payments only.

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

In 2007, the Board and the Company's shareholders approved the 2007 Omnibus
Incentive Stock Plan (the "Omnibus Plan"). The Omnibus Plan permits the issuance
of up to 880,000 shares of the Company's common stock in the form of stock
options, stock appreciation rights, restricted stock, restricted stock units and
performance awards. During the quarter ended June 30, 2008, 2,700 restricted
shares and no stock appreciation rights were granted under the Omnibus Plan.

The Company also continues to maintain its other stock-based incentive plans for
the restricted common stock previously awarded and the options previously issued
and still outstanding. These plans have been superseded by the Omnibus Plan and
accordingly, any available restricted stock and stock option grants not yet
issued have been cancelled.

Restricted shares are amortized to expense over the three-year vesting period.
As of June 30, 2008, the total unrecognized compensation expense related to
non-vested common stock was $1,743,000 and the related weighted-average period
over which it is expected to be recognized is approximately 1.3 years.

Changes in restricted shares outstanding were as follows:

Stock options vest and expire over a period not to exceed seven years. The
Company issues shares out of treasury stock for restricted shares and option
exercises. There were no stock options granted under the old plan during the
six-month periods ended June 30, 2008 and 2007. As of June 30, 2008, the total
unrecognized compensation expense related to non-vested stock options was
$86,000, and the related weighted-average period over which it is expected to be
recognized is approximately 3.6 years

There were 0 and 109,755 stock appreciation rights granted during the three and
six-month periods ended June 30, 2008, respectively. As of June 30, 2008, the
total unrecognized compensation expense related to stock appreciation rights was
$790,000 and the related weighted-average period over which it is expected to be
recognized is 6.6 years. Following are the assumptions used to estimate the
$7.65 per share fair value of stock appreciation rights granted during the
six-month period ended June 30, 2008:

                  -------------------------------------------

The risk-free interest rate is based on the zero-coupon U.S. Treasury yield for
the period equal to the expected life of the options at the time of the grant.
The expected life was derived using the historical exercise activity. The
Company uses historical volatility for a period equal to the expected life of
the rights using average monthly closing market prices of the Company's stock as
reported on The Nasdaq Global Market. The expected dividend yield is based on
the Company's current rate of annual dividends.

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.

The following table represents the components of the net periodic pension costs
for 2007 and an estimate for 2008:

Pension costs recorded to expense were $357,000 and $429,000 for the three-month
periods ended June 30, 2008 and 2007, respectively, and totaled $715,000 and
$832,000 for the six-month periods ended June 30, 2008 and 2007, respectively.
The Company has not made any contribution to the plan during the six-month
period ended June 30, 2008, but expects to contribute at least $1,800,000 in
2008.

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. The
following table represents the components of the net periodic pension costs for
2007 and an estimate for 2008:

Pension costs recorded to expense were $146,000 and $141,000 for the three-month
periods ended June 30, 2008 and 2007, respectively, and were $293,000 and
$227,000 for the six-month periods ended June 30, 2008 and 2007, respectively.

Note 12 - Income Taxes

The Company adopted Financial Accounting Standards Board ("FASB") Interpretation
No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes" effective
January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes
in financial statements and prescribes a recognition threshold and measurement
attribute for financial statement recognition and measurement of a tax position
taken or expected to be taken.

The Company had unrecognized tax benefits of approximately $1,033,000 as of
December 31, 2007. The total amount of federal and state unrecognized tax
benefits at December 31, 2007 that, if recognized, would affect the effective
tax rate was $806,000, net of federal tax benefit. There have been no material
changes to the unrecognized tax benefits during the three and six-month periods
ended June 30, 2008. The Company may realize a reduction of its unrecognized tax
benefits in the next twelve months due to a potential lapse of federal and state
statutes of limitations. The amount of such a potential reduction is not
material.

The Company recognizes interest and penalties related to uncertain tax positions
in income tax expense. The amount of interest accrued for unrecognized tax
benefits as of December 31, 2007 was immaterial and the amount of interest
recognized during the three and six-month periods ended June 30, 2008 was
immaterial.

The Company is subject to income tax in the U. S. federal jurisdiction and
numerous state jurisdictions. U.S. federal income tax returns for tax years 2006
and 2007 remain subject to examination by the Internal Revenue Service. In
addition, the Company is subject to state tax examinations for the tax years
2004 through 2007.

Note 13 - Fair Value of Assets

Effective January 1, 2008, the Company adopted SFAS No. 157 "Fair Value
Measurements" ("SFAS No. 157") and SFAS No. 159 "The Fair Value Option for
Financial Assets and Financial Liabilities" ("SFAS No. 159"). In accordance with
the FASB Staff Position 157-2, "Effective Date of SFAS No. 157," the Company has
not applied the provisions of SFAS No. 157 to nonfinancial assets and
nonfinancial liabilities such as real estate owned and goodwill. The Company
uses fair value measurements to determine fair value disclosures.

The following is a description of valuation methodologies used for assets
recorded at fair value:

Investment Securities Available for Sales - Investment securities
available-for-sale are recorded at fair value on a recurring basis. The
Company's securities available-for sale are measured at fair value using Level 2
valuations. The market evaluation utilizes several sources which include
observable inputs rather than "significant unobservable inputs" and therefore
fall into the Level 2 category. The table below presents the balances of
securities available-for-sale measured at fair value on a recurring basis:

                (In Thousands)                    June 30, 2008
                                                  -------------
                Treasury Securities               $       1,998
                State and Municipal Securities          205,076
                                                  -------------
                                                  $     207,074
                                                  =============

Loans - The Company does not record loans at fair value on a recurring basis
other than loans that are considered impaired. Once a loan is identified as
impaired, management measures impairment in accordance with SFAS No. 114,
"Accounting by Creditors for Impairment of a Loan." At June 30, 2008, all
impaired loans were evaluated based on the fair value of the collateral. The
fair value of the collateral is based upon an observable market price or current
appraised value and therefore, the Company classifies these assets as
nonrecurring Level 2. The total principal balance of impaired loans measured at
fair value at June 30, 2008 was $1,967,000.

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 large manufacturing, distribution and retail enterprises from its
processing centers in St. Louis, Missouri, Columbus, Ohio, Boston,
Massachusetts, Greenville, South Carolina and Wellington, Kansas. The Company's
services include freight invoice rating, payment processing, auditing, and the
generation of accounting and transportation information. Cass also processes and
pays utility invoices, which includes electricity, gas and telecommunications
expenses and is a provider of telecom expense management solutions. Cass
extracts, stores and presents information from freight, utility and
telecommunication invoices, assisting its customers' transportation, energy and
information technology managers in making decisions that will enable them to
improve 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 as
required and provide Internet-based tools for analytical processing. The Company
also, through Cass Commercial Bank, its St. Louis, Missouri based bank
subsidiary (the "Bank"), provides banking services in the St. Louis metropolitan
area Orange County, California and other selected cities in the United States.
In addition to supporting the Company's payment operations, the Bank provides
banking services to its target markets, which include privately-owned businesses
and churches and church-related ministries.

The specific payment and information processing services provided to each
customer are developed individually to meet each customer's requirements, which
can vary greatly. In addition, the degree of automation such as electronic data
interchange ("EDI"), imaging, and web-based 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 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 will also influence revenue and
profitability, such as changes in the general level of interest rates, which
have a significant effect 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 paid on its deposits. The Bank also
assesses fees on other services such as cash management services.

Industry-wide factors that impact the Company include the acceptance by large
corporations of the outsourcing of key business functions such as freight,
utility and telecommunication payment and audit. Acquisition and merger activity
involving our customers, business partners, and competitors can also impact the
Company. 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, deregulation of energy
costs and consolidation of telecommunication providers. 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 the loan portfolio. The general
level of interest rates also has a significant effect on the revenue of the
Company.

Currently, management views Cass' major opportunity as the continued expansion
of its payment and information processing service offering and customer base.
While the current economic slow-down may reduce the short-term growth rate,
management remains optimistic about the long-term prospects for growth. With the
recent significant drop in short-term interest rates, the major challenge faced
by Cass is the prudent management of earning assets and interest bearing
liabilities. Management actively monitors Cass' balance sheet and has already
taken a number of actions to reduce the interest rate sensitivity of its earning
assets and lower the cost of its interest-bearing liabilities in an effort to
mute the effect that the lower interest rate environment has on Cass.

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, 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.

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 both segments of the
Company. The impact and associated risks related to these policies on the
Company's business operations are discussed in the "Provision and Allowance for
Loan Losses" section of this report.

Impairment of Assets. The Company periodically evaluates certain long-term
assets such as intangible assets including goodwill, foreclosed assets 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 both segments of the Company and require
significant management assumptions and estimates that could result in materially
different results if conditions or underlying circumstances change.

Income Taxes. The objectives of accounting for income taxes are to recognize the
amount of taxes payable or refundable for the current year and deferred tax
liabilities and assets for the future tax consequences of events that have been
recognized in an entity's financial statements or tax returns. Judgment is
required in addressing the future tax consequences of events that have been
recognized in the Company's financial statements or tax returns such as the
realization of deferred tax assets, changes in tax laws or interpretations
thereof. In addition, the Company is subject to the continuous examination of
its income tax returns by the Internal Revenue Service and other taxing
authorities. Effective January 1, 2007, the Company adopted FIN No. 48,
"Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement
No. 109." FIN No. 48 provides guidance for the recognition threshold and
measurement attribute for financial statement recognition and measurement of a
tax position taken or expected to be taken in a tax return. See Note 12 to the
financial statements.

Pension Plans. The amounts recognized in the consolidated financial statements
related to pension are determined from actuarial valuations. Inherent in these
valuations are assumptions including expected return on plan assets, discount
rates at which the liabilities could be settled at December 31, 2007, rate of
increase in future compensation levels and mortality rates. These assumptions
are updated annually and are disclosed in Note 12 to the consolidated financial
statements filed with the Company's annual report on Form 10-K for the year
ended December 31, 2007. Pursuant to Statement of Financial Accounting Standards
No. 158, "Employers' Accounting for Defined Benefit Pension and Other
Postretirement Plans" ("SFAS No. 158"), the Company has recognized the funded
status of its defined benefit postretirement plan in its statement of financial
position and has recognized changes in that funded status through comprehensive
income. The funded status is measured as the difference between the fair value
of the plan assets and the benefit obligation as of the date of its fiscal
year-end.

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, 2008
("Second Quarter of 2008") compared to the three-month period ended June 30,
2007 ("Second Quarter of 2007") and the six-month period ended June 30, 2008
("First Half of 2008") compared to the six-month period ended June 30, 2007
("First Half of 2007"). 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 2007 annual report on Form 10-K. Results of operations for
the Second Quarter of 2008 are not necessarily indicative of the results to be
attained for any other period.

Fee Revenue and Other Income from Continuing Operations

The Company's fee revenue is derived mainly from freight and utility processing
and payment fees. As the Company provides its processing and payment services,
it is compensated by service fees which are typically calculated on a per-item
basis and by the accounts and drafts payable balances generated in the payment
process which can be used to generate interest income. Processing volumes
related to fees and accounts and drafts payable for the three and six-month
periods ended June 30, 2008 and 2007 were as follows:



                                                         Three Months Ended                          Six Months Ended

*Core invoices exclude parcel shipments.

Second Quarter of 2008 compared to Second Quarter of 2007:

Freight transaction volume and invoice dollar volume for the Second Quarter of
2008 increased compared to the same period in 2007 due to new business and
growth in existing customer volume. The dollar volume also increased due to
higher average bills because of fuel surcharges. The increase in transaction and
dollar volume from utility transactions resulted primarily from new customers as
the growth of this division continues.

Bank service fees decreased $83,000 or 19% primarily due to the elimination of
correspondent banking services which was completed in the Second Quarter of
2008. Other income decreased $9,000 in the Second Quarter of 2008.

First Half of 2008 compared to First Half of 2007:

Freight and utility transaction volume and dollar volume increased for the First
Half of 2008 compared to 2007 due to the same factors discussed above for the
Second Quarter of 2008.

Bank service fees decreased $145,000 or 18% due to the same factors discussed
above for the Second Quarter of 2008. Other income increased $3,000 in the First
Half of 2008.

Net Interest Income

Net interest income is the difference between interest earned on loans,
investments, and other earning assets and interest expense on deposits and other
interest-bearing liabilities. Net interest income is a significant source of the
Company's revenues. The following table summarizes the changes in net interest
income and related factors for the three and six-month periods ended June 30,
2008 and 2007:

*Presented on a tax-equivalent basis assuming a tax rate of 35%.

Second Quarter of 2008 compared to Second Quarter of 2007:

The increase in tax equivalent net interest income was due to a modest increase
in average earning assets combined with a shift in the balances of earning
assets from the relatively lower yielding federal funds sold and other
short-term investments to longer term and relatively higher yielding non-taxable
state and municipal securities . Yields on earning assets and rates paid on
deposit accounts both decreased as the general level of interest rates
decreased.

Total average loans increased $29,285,000, or 6%, to $557,406,000. Total average
investment in debt and equity securities increased $74,892,000 or 57% to
$205,303,000 as the Company invested a portion of the increase in payables in
non-taxable state and municipal securities. Total average federal funds sold and
other short-term investments decreased $90,091,000 or 69% to $40,902,000. For
more information on the changes in net interest income please refer to the
tables that follow.

First Half of 2008 compared to First Half of 2007:

The increase in tax equivalent net interest income was due to a modest increase
in average earning assets combined with a shift in the balances of earning
assets from the relatively lower yielding federal funds sold and other
short-term investments to longer term and relatively higher yielding non-taxable
state and municipal securities . Yields on earning assets and rates paid on
deposit accounts both decreased as the general level of interest rates
decreased.

Total average loans increased $8,358,000 or 2% to $530,802,000. Total average
investment in debt and equity securities increased $68,301,000 or 55% to
$191,946,000 as the Company invested a portion of the increase in payables in
non-taxable state and municipal securities. Total average federal funds sold and
other short-term investments decreased $59,357,000 or 43% to $79,155,000. For
more information on the changes in net interest income please refer to the
tables that follow.

The Company is negatively affected by decreases in the level of interest rates
due to the fact that its rate-sensitive assets exceed its rate-sensitive
liabilities. 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.

Distribution of Assets, Liabilities and Stockholders' Equity; Interest Rate and
Interest Differential

The following table shows the condensed average balance sheets for each of the
periods reported, the tax-equivalent interest income and expense on each
category of interest-earning assets and interest-bearing liabilities, and the
average yield on such categories of interest-earning assets and the average
rates paid on such categories of interest-bearing liabilities for each of the
periods reported.

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 2007
      Consolidated Financial Statements, filed with the Company's 2007 Annual
      Report on Form 10-K.

3.    Interest income on loans includes net loan fees of $64,000 and $48,000 for
      the Second Quarter of 2008 and 2007, respectively.

4.    Interest income is presented on a tax-equivalent basis assuming a tax rate
      of 35%. The tax-equivalent adjustment was approximately $1,099,000 and
      $603,000 for the Second Quarter of 2008 and 2007, 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.

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 2007
      Consolidated Financial Statements, filed with the Company's 2007 Annual
      Report on Form 10-K.

3.    Interest income on loans includes net loan fees of $118,000 and $94,000
      for the First Half of 2008 and 2007, respectively.

4.    Interest income is presented on a tax-equivalent basis assuming a tax rate
      of 35%. The tax-equivalent adjustment was approximately $2,038,000 and
      $1,133,000 for the First Half of 2008 and 2007, 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.

Provision and Allowance for Loan Losses

An important determinant of the Company's operating results is the provision for
loan losses and the level of loans charged off. There was a $650,000 and
$225,000 provision for loan losses during the Second Quarter of 2008 and the
Second Quarter of 2007, respectively. There was a $1,100,000 and $450,000
provision for loan losses during the First Half of 2008 and the First Half of
2007, respectively. As discussed below, the Company continually analyzes the
outstanding loan portfolio based on the performance, financial condition and
collateralization of the credits. There were $817,000 and $204,000 of net loan
charge-offs in the Second Quarter of 2008 and 2007, respectively. There were
$1,290,000 of net loan charge-offs in the First Half of 2008 and $199,000 in the
First Half 2007.

The allowance for loan losses at June 30, 2008 was $6,090,000 and at December
31, 2007 was $6,280,000. The ratio of allowance for loan losses to total loans
outstanding at June 30, 2008 was 1.07% compared to 1.26% at December 31, 2007.
Nonperforming loans were $3,265,000 or .57% of total loans at June 30, 2008
compared to $2,481,000 or .50% of total loans at December 31, 2007.

At June 30, 2008, nonperforming loans, which are also considered impaired,
consisted of $2,919,000 in non-accrual loans as shown in the following table.
This total consists of eight loans to borrowers with businesses in financial
trouble or in the process of liquidation. Nonperforming loans at December 31,
2007 consisted of $1,985,000 in five non-accrual loans, four of which are
included in the June 30, 2008 total. One loan was charged off in the Second
Quarter of 2008. Total nonperforming loans increased $410,000 from June 30, 2007
to June 30, 2008. This increase was primarily due to the addition of six
commercial loans which are in financial trouble offset by the charge-off of two
loans.

In addition to the nonperforming loans discussed above, at June 30, 2008,
approximately $2,975,000 of loans not included in the table below was identified
by management as having potential credit problems. They may also be classified
for regulatory purposes. These loans are excluded from the table due to the fact
they are current under the original terms of the loans, however circumstances
have raised doubts as to the ability of the borrowers to comply with the current
loan repayment terms. These loans are closely monitored by management and have
specific reserves established for the estimated loss exposure.

The allowance for loan losses has been established and is maintained to absorb
probable losses 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 impaired
commercial, real estate, and construction loans based on individual review of
these loans and an estimate of the borrower's ability to repay the loan given
the availability of collateral, other sources of cash flow and collection
options available. 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, the general
reserve also includes a 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 Company had no sub-prime mortgage loans or residential development loans in
its portfolio as of June 30, 2008. The Bank had one property carried as other
real estate owned of $1,388,000 as of June 30, 2008 and December 31, 2007. The
Bank had no properties carried as other real estate owned as of June 30, 2007.

Operating Expense from Continuing Operations

Total operating expense for the Second Quarter of 2008 increased $576,000 or 4%
to $16,508,000 compared to the Second Quarter of 2007 due primarily to expenses
related to the 12% growth in processing activity. Total operating expense for
the First Half of 2008 increased $1,603,000 or 5% to $32,868,000 compared to the
First Half of 2007 due primarily to expenses related to the 9% growth in
processing activity.

Salaries and benefits expense for the Second Quarter of 2008 increased $600,000
or 5% to $12,496,000 compared to the Second Quarter of 2007 and increased
$1,498,000 or 6% to $24,933,000 for the First Half of 2008 compared to the First
Half of 2007 primarily due to additional headcount to service new transaction
business and an increase in bonuses related to the earnings increase over the
comparable period last year.

Occupancy expense for the Second Quarter of 2007 increased $28,000 or 5% to
$560,000 from the Second Quarter of 2007 and increased $78,000 or 8% from the
First Half of 2007 compared to the First Half of 2008.

Equipment expense for the Second Quarter of 2008 decreased $5,000 or less than
1% compared to the Second Quarter of 2007 and increased $7,000 or less than 1%
from the First Half of 2007.

Amortization of intangible assets was $70,000 for the Second Quarter of 2008 and
2007 and $140,000 for the First Half of 2008 and 2007.

Other operating expense for the Second Quarter of 2008 decreased $47,000, or 2%
compared to the Second Quarter of 2007 and decreased $20,000 for the First Half
of 2008 compared to the First Half of 2007. The decreases were due to lower
legal and outside services expenses.

Income tax expense for the Second Quarter of 2008 decreased $303,000 or 16%
compared to the Second Quarter of 2007 and decreased $862,000 for the First Half
of 2008 compared to the First Half of 2007. The effective tax rate was 26.5% and
31.7% for the Second Quarters of 2008 and 2007, respectively and was 27.1% and
32.6% for the First Halves of 2008 and 2007, respectively. The decreases reflect
the impact of the increase in interest income relating to tax-exempt securities.

Financial Condition

Total assets at June 30, 2008 were $905,716,000, an increase of $2,676,000, or
less than 1% from December 31, 2007. The most significant changes in asset
balances during this period were a decrease of $119,997,000 or 80% in federal
funds sold and other short-term investments and increases of $35,368,000 and
$71,959,000 in securities available for sale and loans, respectively. Changes in
federal funds sold and other short-term investments reflect the Company's daily
liquidity position and are affected by the changes in the other asset balances
and changes in deposit and accounts and draft payable balances.

Total liabilities at June 30, 2008 were $803,356,000, a decrease of $232,000,
less than 1% from December 31, 2007. Total deposits at June 30, 2008 were
$236,836,000, a decrease of $36,760,000 or 13% from December 31, 2007. Accounts
and drafts payable at June 30, 2008 were $548,028,000, an increase of
$34,294,000 or 7%. Total shareholders' equity at June 30, 2008 was $102,360,000,
a $2,908,000 or 3% increase from December 31, 2007.

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 (for average balances refer to the tables under the "Distribution of
Assets, Liabilities and Stockholders' Equity; Interest Rate and Interest
Differential" section of this report).

The increase in total shareholders' equity resulted from net income of
$8,585,000, $491,000 from stock-based compensation expense offset by dividends
paid of $2,208,000 ($.12 per share), the repurchase of treasury shares of
$3,984,000, an increase in other comprehensive loss of $181,000 and other
miscellaneous activity of $205,000.

Liquidity and Capital Resources

The balance of liquid assets consists of cash and cash equivalents, which
include cash and due from banks, federal funds sold and money market funds, and
was $63,049,000 at June 30, 2008, a decrease of $113,021,000 or 64% from
December 31, 2007. At June 30, 2008 these assets represented 7% 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 securities was $207,074,000 at June 30, 2008, an
increase of $35,368,000 from December 31, 2007. These assets represented 23% of
total assets at June 30, 2008. Of this total, 99% were state and political
subdivision securities and 1% was U.S. Treasury securities. Of the total
portfolio, 4% mature in one year, 21% mature in one to five years, and 75%
mature in five or more years. During the Second Quarter of 2008 the Company did
not sell any securities.

The Bank has unsecured lines of credit at correspondent banks to purchase
federal funds up to a maximum of $39,000,000. Additionally, the Bank maintains a
line of credit at unaffiliated financial institutions in the maximum amount of
$81,568,000 collateralized by commercial and real estate loans.

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 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 $13,706,000 for the First
Half of 2008 compared with $13,305,000 for the First Half of 2007. This increase
is attributable to the increases in net income of $207,000, depreciation and
amortization of $740,000, provision for loan losses of $650,000, stock-based
compensation expense of $172,000, the decrease in net income taxes deferred and
payable of $735,000 and the other normal fluctuations in 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. Other causes for the changes in these account balances are 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 2008.

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 Federal Deposit Insurance Corporation ("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, 2008 and
December 31, 2007:

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.

Impact of New Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements". The
objective of SFAS No. 157 is to increase consistency and comparability in fair
value measurements and to expand disclosures about fair value measurements. SFAS
No. 157 defines fair value, establishes a framework for measuring fair value in
generally accepted accounting principles, and expands disclosures about fair
value measurements. The Company adopted this statement as of January 1, 2008 and
there was no effect on the Company's consolidated financial statements.

In February 2007, the FASB issued Statement No. 159, "The Fair Value Option for
Financial Assets and Financial Liabilities" ("SFAS No. 159"). SFAS No. 159
defines fair value, establishes a framework for measuring fair value in
generally accepted accounting principles and expands disclosures about fair
value measurements. The Company adopted this statement as of January 1, 2008 and
there was no effect on the Company's consolidated financial statements.


                                      -23-


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, 2007, 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, 2008 has changed materially from that at December 31, 2007.

ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures designed to provide
reasonable assurance that the information it is required to disclose in the
reports it files with the Securities and Exchange Commission ("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 Officer and
Principal Financial Officer have evaluated the Company's disclosure controls and
procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities
Exchange Act of 1934, as amended) as of June 30, 2008 and based on their
evaluation, believe that, as of June 30, 2008, these controls and procedures
were effective at the reasonable assurance level 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 2008 in the Company's internal
control over financial reporting identified by the Chief Executive Officer and
Principal Financial Officer in connection with their evaluation that materially
affected or are reasonably likely to materially affect the Company's internal
control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f)
under the Securities Exchange Act of 1934, as amended).

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 its
            businesses. Management believes none of these proceedings, if
            determined adversely, would have a material effect on the business
            or financial conditions of the Company or its subsidiaries.

ITEM 1A.    RISK FACTORS

            The Company has included in Part I, Item 1A of its Annual Report on
            Form 10-K for the year ended December 31, 2007, a description of
            certain risks and uncertainties that could affect the Company's
            business, future performance or financial condition (the "Risk
            Factors"). There are no material changes to the Risk Factors as
            disclosed in the Company's 2007 Annual Report on Form 10-K.

ITEM 2.     UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

            The Company maintains a treasury stock buyback program pursuant to
            which the Board of Directors has authorized the repurchase of up to
            300,000 shares of the Company's common stock. This repurchase plan
            was updated by the Board of Directors on January 22, 2008 and
            replaced the Company's previous plan under which 120,000 shares had
            remained available for repurchase. The stock repurchase program may
            be modified or discontinued at any time.

            The following table sets forth information about the Company's
            repurchases of its $0.50 par value Common Stock, its only class of
            stock registered pursuant to Section 12 of the Securities Exchange
            Act of 1934, as amended:
