association; an approval was also received on May 29, 1992 from the Federal
Reserve Board to form a one-bank holding company. On September 15, 1992, the

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




                  The following discussion addresses the factors that have
affected Sarasota BanCorporation, Inc.'s (the "Company") financial condition and
results of operations reflected in the Company's unaudited financial statements
for the second quarter ended June 30, 1998.

RESULTS OF OPERATIONS

                  The Company's net income for the second quarter of 1998 was
$187,600, a 11.9% increase compared to $167,623 for the same period in 1997.
Earnings per share increased to .40 in the second quarter of 1998 compared to
 .36 per share for the same period in 1997. Net income for the six months ended
June 30, 1998 was $337,838 compared to $305,429 for the same period in 1997, an
increase of 32,409 or 10.6%. The increase in net income is primarily
attributable to a 44.1% and a 43.0% increase in interest and fees on loans for
the three and six month periods ended June 30, 1998, respectively.

                  Net interest income after provision for loan losses for the
second quarter of 1998 increased $262,560 or 53.8% to $750,684 from a balance of
$488,124 for the second quarter of 1997. Net interest income after provision for
loan losses for the six months ended June 30, 1998 increased $465,589 or 49.6%
to $1,403,898 from a balance of $938,309 for the same period in 1997. The
increase in net interest income resulted primarily from an increase in loan
volume and a corresponding increase in interest and fees on loans. The cost of
deposits averaged 4.43% for the second quarter of 1998 compared to 4.24% for the
second quarter of 1997. The net interest margin for the six month period ended
June 30, 1998 was 4.28% on average earning assets of $64,232,000. For the same
period in 1997, the net interest margin was 4.16% on average earning assets of
$51,414,072. The increase in net interest margin is reflective of growth in
higher priced consumer loan accounts.

                  Non-interest expense for the second quarter of 1998 increased
$140,033 or 56.2% as compared to the second quarter of 1997. Non-interest
expense increased $240,489 or 32.8% for the six month period ended June 30, 1998
as compared to the same period of 1997. This increase is primarily the result of
increased employee salaries and benefits, data processing fees and loan
servicing fees.

                  Non-interest income increased $7,950 or 16.1% during the
second quarter ended June 30, 1998 as compared to the same period in 1997.
Non-interest income also increased $6,309 or 5.9% for the six month period ended
June 30, 1998 as compared to the same period in 1997. The increase in
non-interest income is attributable to a overdraft service fees on depository
accounts.

FINANCIAL CONDITION

                  For the six month period ended June 30, 1998, the company
experienced continued asset, loan and deposit growth. Total assets increased
15.1% to $68,946,165 for the six month period ended June 30, 1998 from
59,920,530 at December 31, 1997. This increase is primarily attributable to an
increase in loans of approximately $7.5 million during the period.

MANAGEMENT
PAGE 2


                  The allowance for loan loss provision for the second quarter
of 1998 was $19,000 compared to $72,300 in the second quarter of 1997. The
reserve balance for loan losses as of June 30, 1998 was $529,100 as compared to
$482,400 at December 31, 1997. At June 30, 1998, the allowance for loan losses
represented 1.10% of total loans outstanding. Management considers the allowance
to be adequate based upon evaluations of specific loans and the weighting of
various loan categories as suggested by the Bank's internal loan rating system.
The provision for loan losses is based upon management's continuing analysis and
evaluation of various factors, including current economic conditions, the size
of the loan portfolio, past loan loss experience, underlying collateral value,
the Bank's internal rating system and other factors deemed relevant by
management.

                  Through the second quarter of 1998, there were no charged-off
loans and recoveries totaled $14,000 or a net of <00.03> percent of total loans
outstanding. The ratio of non-performing loans (including loans 90 days or more
past due) to total outstanding loans was $120,000 or .25% as of June 30 1998
compared to 0.16% as of the same period in 1997. At year ended December 31,
1997, non-performing loans were $11,800 or .02% of loans outstanding. The
increase in non-performing loans as compared to year ended December 31, 1997 is
primarily attributable to several consumer loans past due from 30 to 90 days.
There was one loan in the amount of $1,000 past due in excess of 90 days as of
June 30, 1998.


CAPITAL ADEQUACY

                  Federal banking regulators have established certain capital
adequacy standards required to be maintained by banks and bank holding
companies. These regulations establish minimums of risk-based capital of 4% for
core capital (tier 1), 8% for total risk-based capital, and at least 3% for the
leverage ratio. Three percent is the minimum leverage ratio for the most highly
rated banks. All other banks are required to meet a minimum of at least 100 or
200 basis points above the 3% level. The Company's tier 1 risk-based capital
ratio at June 30, 1998 was 11.72%, its total risk-based capital ratio was
12.80%, and its leverage ratio was 8.39%.


LIQUIDITY

                  The Company views liquidity as the ability to provide for the
credit needs of the market and to provide funds for deposit withdrawals. With a
loan to deposit ratio of 75.16% at June 30, 1998, cash and due from banks of
$1,958,664 and federal funds sold of $3,758,000, the Company does not anticipate
any events which would require liquidity beyond that which is available through
deposit growth or its investment portfolio. The Company actively manages the
levels, types, and maturities of earning assets in relation to the sources
available to fund current and future needs to ensure adequate funding will be
available at all times. There are no known trends or any known commitments or
uncertainties that will result in the Company's liquidity increasing or
decreasing in any material way.
