incorporated under the laws of the State of Florida on December 28, 1990, for
the purpose of becoming a bank holding company with respect to a proposed de
novo bank, Sarasota Bank (the "Bank") Sarasota, Florida. Prior to formation of
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 organizers' 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 as reflected in the Company's unaudited financial statements for
the first quarter ended March 31, 1999.

RESULTS OF OPERATIONS

         The Company's net income for the first quarter of 1999 was $220,931, a
47.0% increase compared to $150,238 for the same period in 1998. Earnings per
share increased to $0.47 in the first quarter of 1999 compared to $0.32 per
share for the same period in 1998. The increase in net income is primarily
attributable to a 32.6% increase in interest and fees on loans for the
three-month period ended March 31, 1999. Interest on investment securities and
on Federal Funds Sold also showed increases of 40.1% and 54.0%, respectively,
for the three-month period ended March 31, 1999.

         Net interest income after the provision for loan losses for the first
quarter of 1999 increased $227,088 or 34.8% to $880,302 from a balance of
$653,214 for the first quarter of 1998. 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 4.15% during the
first quarter of 1999 compared to 4.42% for the first quarter of 1998. The net
interest margin for the three months ended March 31, 1999 was 4.42% on average
earning assets of $84,997,000. For the same period in 1998, the net interest
margin was 4.26% on average earning assets of $60,873,900. 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 1999 increased $141,886,
or 30.4%, as compared to the first quarter of 1998. This increase is primarily
the result of increased employee salaries and benefits and loan servicing fees.

         Non-interest income decreased $18,991, or 34.1%, during the first
quarter ended March 31, 1999 as compared to the same period in 1998. The
decrease in non-interest income is attributable an increase in daily overdraft
fees for demand deposit accounts.

FINANCIAL CONDITION

         For the three month period ended March 31, 1999, the Company
experienced continued asset, loan and deposit growth. Total assets increased
12.2% to $89,351,332 for the three month period ended March 31, 1999 from
$78,465,475 at December 31, 1998. This increase is primarily attributable to an
increase in loans of approximately $3.8 million and an increase in Federal Funds
Sold of approximately $7.6 million during this period.

         The allowance for loan loss provision for the first quarter of 1999 was
$46,100 compared to $13,700 in the first quarter of 1998. The reserve balance
for loan losses as of March 31, 1999 was $600,000 as compared to $507,300 at
December 31, 1998. At March 31, 1999, the allowance for



                                      -7-
<PAGE>   8

loan losses represented 1.03% 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 1999, there was one charged-off loan in
the amount of $6,000 and recoveries totaled $2,350, or a net of .01% of total
loans outstanding. The ratio of non-performing loans (including loans 90 days or
more past due) to total outstanding loans was $256,055 or .44% of total
outstanding loans as of March 31, 1999 compared to .02% of total outstanding
loans as of the same period in 1998. At year ended December 31, 1998,
non-performing loans were $270,900 or .50% of total 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, 1999.

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 4.0% for core capital
(tier 1 capital), 8.0% for total risk-based capital, and at least 3.0% 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 3.0% level. The Company's tier 1 risk-based capital
ratio at March 31, 1999 was 10.47%, its total risk-based capital ratio was
11.45%, and its leverage ratio was 7.58%, well above the required minimums.

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 73.80% at March 31, 1999, cash and due from banks of $2,840,649
and federal funds sold of $9,260,000, 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.

YEAR 2000

         A critical issue affecting companies that rely extensively on
electronic data processing systems, such as the Company , is the Year 2000
issue. The Year 2000 issue has arisen due to the

widespread use of computer programs that rely on two-digit date codes to perform
computations or decision-making functions. Many of these programs may fail as a
result of their inability to properly interpret date codes beginning January 1,
2000. For example, such programs may misinterpret "00" as the year 1900 rather
than 2000. In addition, some equipment, being controlled by microprocessor chips
may not deal appropriately with the year "00." This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions or engage in similar
normal business activities.

         The Bank uses a third-party vendor for processing its primary banking
applications. During 1998, the company developed a plan to address the Year 2000
issue, conduct a comprehensive review of the Company's systems and ensure that
the company takes any necessary measures. The company believes that its systems
and those of the Bank are currently Year 2000 compliant and does not believe
that material expenditures will be necessary to implement any further
modifications. The Bank will complete its testing phase with its data processing
vendor during the second quarter of 1999. All coding changes with the data
processing vendor have been completed and are currently in use. The Bank does
not believe that material expenditures will be necessary to implement any
further modifications with its data processing vendor. As of March 31, 1999, the
Company had spent approximately $25,000 to help ensure that its systems would be
Year 2000 compliant. The Company's data processing vendor has assured the
Company that its systems will be Year 2000 compliant well in advance of the Year
2000. The Company's contingency plans relative to Year 2000 issues have not been
finalized. Management will develop and modify a "worst case scenario"
contingency plan which will, among other things, anticipate that the Company's
deposit customers will have increased demands for cash in the latter part of
1999. The plan also provides for copies of documents to be produced in case of
equipment failure, utilization of security personnel in case of security
equipment failure, manual posting of transactions, hiring of temporary
additional personnel and telephone verification of information normally received
by electronic means. However, there can be no assurance that unforeseen
difficulties or costs will not arise. In addition, there can be no assurance
that the systems of other companies on which the Company's systems rely, such as
the Bank's data processing vendor, will be modified on a timely basis, or that
the failure by another company to properly modify its systems will not
negatively impact the Company's systems or operations.
