the Company, the Company's organizers formed a partnership to commence
organizing a bank holding company. The partnership was subsequently merged into
the Company as of December 30, 1990. As a result, each organizer's capital
account in the partnership was exchanged for common stock of the Company and all
assets of the partnership were contributed as capital to the Company in
consideration of the issuance of its common stock to the organizers. On
September 15, 1992, the organizers received approval from the Office of the
Comptroller of the State of Florida for the organization of a new state banking
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
Company acquired 100% of the Bank's capital stock by injecting $4.25 million
into the Bank's capital accounts.

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
first quarter ended March 31, 2000.


RESULTS OF OPERATIONS

         The Company's net income for the first quarter of 2000 was $311,808, a
41.1% increase compared to $220,931 for the same period in 1999. Earnings per
share increased to $0.56 in the first quarter of 2000 compared to $0.40 per
share for the same period in 1999. The increase in net income is primarily
attributable to a 30.5% increase in interest and fees on loans for the
three-month period ended March 31, 2000. Interest on investment securities
increased 11.3%, while interest on Federal Funds sold decreased 23.3% for the
three-month period ended March 31, 2000.

         Net interest income after the provision for loan losses for the first
quarter of 2000 increased $171,476, or 19.5%, to $1,051,778 from a balance of
$880,302 for the first quarter of 1999. 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 4.68% for the first
quarter of 2000 compared to 4.15% for the first quarter of 1999. The net
interest margin for the three months ended March 31, 2000 was 4.53% on average
earning assets of $94,700,200. For the same period in 1999, the net interest
margin was 4.42% on average earning assets of $84,997,900. The increase in net
interest margin is reflective of growth in higher priced consumer loan accounts
and lower priced deposits.

         Non-interest expense for the first quarter of 2000 increased $87,674,
or 14.4%, as compared to the first quarter of 1999. This increase is primarily
the result of increased data processing fees and loan servicing fees.

         Non-interest income increased $80,175, or 107.4%, during the first
quarter ended March 31, 2000 as compared to the same period in 1999. The
increase in non-interest income is attributable in part to fees received from a
developer in connection with the Bank's agreement to temporarily close its drive
thru facility while a three story garage was built directly over the top of the
facility. Another attribution of the increase was associated with a new accounts
receivable loan service initiated by the Bank during the fourth quarter of 1999.

FINANCIAL CONDITION

         For the three month period ended March 31, 2000, the Company
experienced continued asset, loan and deposit growth. Total assets increased
8.2% to $102,947,658 for the three month period ended March 31, 2000 from
$95,189,848 at December 31, 1999. This increase is primarily attributable to an
increase in loans of approximately $2.4 million, an increase in Federal Funds
Sold of approximately $4.4 million and an increase in Securities Available for
Sale of approximately 2.9 million during this period.

         The allowance for loan loss provision for the first quarter of 2000 was
$44,600 compared to $46,100 in the first quarter of 1999. The reserve balance
for loan losses as of March 31, 2000 was $820,100 as compared to $773,500 at
December 31, 1999. At March 31, 2000, 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 first quarter of 2000, there was one charged-off loan in
the amount of $1,000 and recoveries totaled $3,000, or a net of 0.003% of total
loans outstanding. The ratio of non-performing loans (including loans 90 days or
more past due) to total outstanding loans was .69% of total loans outstanding as
of March 31 2000 compared to 0.44% of total loans outstanding as of the same
period in 1999. At December 31, 1999, non-performing loans were $361,000, or
 .50%, of loans outstanding. The non-performing loans are primarily consumer
loans and all of the non-performing loans are fully secured. There were no other
loans past due in excess of 90 days as of March 31, 2000.

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 capital), 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 March 31, 2000 was 10.02%, its total risk-based capital ratio was
11.09%, and its leverage ratio was 7.72%.

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 79.43% at March 31, 2000, cash and due from banks of $2,191,025
and federal funds sold of $4,935,000, 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.

 CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

         The Company may, from time to time, make written or oral
forward-looking statements, including statements contained in the Company's
filings with the Securities and Exchange Commission (the "Commission") and its
reports to stockholders. Such forward-looking statements are made based on
management's belief as well as assumptions made by, and information currently
available to, management pursuant to "safe harbor" provisions of the Private
Securities Litigation Reform Act of

1995. The Company's actual results may differ materially from the results
anticipated in these forward- looking statements due to a variety of factors,
including governmental monetary and fiscal policies, deposit levels, loan
demand, loan collateral values, securities portfolio values and interest rate
risk management; the effects of competition in the banking business from other
commercial banks, savings and loan associations, mortgage banking firms,
consumer finance companies, credit unions, securities brokerage firms, insurance
companies, money market mutual funds and other financial institutions operating
in the Company's market area and elsewhere, including institutions operating
through the Internet; changes in acquisitions; failure of assumptions underlying
the establishment of reserves for loan losses, including the value of collateral
underlying delinquent loans and other factors. The Company cautions that such
factors are not exclusive. The Company does not undertake to update any
forward-looking statements that may be made form time to time by, or on behalf
of, the Company.
