                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS
                                  JUNE 30, 2000

The most significant changes in the Corporation's Balance Sheet since December
31, 1999 are increases in loans and investment securities of $4,800,000 and
$2,300,000 respectively offset by a decrease in cash and cash equivalents of
$10,000,000.

Total assets decreased by approximately $2,100,000 mostly because of a decrease
in deposits of approximately $3,000,000.

Also noteworthy is an increase of $150,000 in the allowance for credit losses,
which resulted from $150,000 in credit loss provisions. At June 30, 2000 the
allowance for credit losses totaled $950,000, which represented 1.9% of total
loans and 33% of past due and non-accrual loans.

The results of operation for the first half of 2000, compared to the same period
of 1999, show an increase in income before taxes of approximately $220,000. The
main component of this increase is a $295,000 increase in net interest income.
This increase is analyzed in detail on page 9.

In addition, service fees and other non-interest income increased by $53,000 and
$52,000, respectively. The increase in service fees was the result of a $61,000
increase in charge card merchant income and the increase in other non-interest
income resulted from a $57,000 gain on the sale of real estate acquired through
foreclosure.

On the negative side, non-interest expenses increased by $105,000, which was
mainly due to a $91,000 increase in salaries, wages and employee benefits.

The Corporation continues to be "Well Capitalized" which is the highest
classification a bank can receive. At June 30, 2000 our total risk-based capital
ration was 31.7%, which is almost four times the regulatory requirement.

In Management's opinion, the Corporation's liquidity position is strong, based
on its high level of core deposits, the stability of its other funding sources
and the support provided by its capital base.
