Horizon Bancorporation, Inc.
Notes to Consolidated Financial Statements (Unaudited)
September 30, 2002

Note 1 - Basis of Presentation

The accompanying financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-QSB. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month and nine-month periods ended September 30, 2002 are not necessarily indicative of the results that may be expected for the year ending December 31, 2002. These statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in Form 10-KSB for the year ended December 31, 2001.

Note 2 - Summary of Organization

Horizon Bancorporation, Inc., Bradenton, Florida (the "Company"), is a one-bank holding company with respect to Horizon Bank, Bradenton, Florida (the "Bank"). The Company commenced banking operations on October 25, 1999 when the Bank commenced operations. The Bank is primarily engaged in the business of obtaining deposits and providing commercial, consumer and real estate loans to the general public. The Bank's depositors are each insured up to $100,000 by the Federal Deposit Insurance Corporation (the "FDIC") subject to certain limitations imposed by the FDIC.

The Company is authorized to issue up to 25.0 million shares of its $.01 par value per share common stock. Each share is entitled to one vote and shareholders have no preemptive or conversion rights. As of September 30, 2002 and December 31, 2001, there were 1,147,410 and 1,146,077 shares, respectively, of the Company's common stock issued and outstanding. Additionally, the Company has authorized the issuance of up to 1.0 million shares of its $.01 par value per share preferred stock. The Company's Board of Directors may, without further action by the shareholders, direct the issuance of preferred stock for any proper corporate purpose with preferences, voting powers, conversion rights, qualifications, special or relative rights and privileges which could adversely affect the voting power or other rights of shareholders of common stock. As of September 30, 2002 and December 31, 2001, there were no shares of the Company's preferred stock issued or outstanding.

Note 3 - Recent Accounting Pronouncements

Statement of Financial Accounting Standards No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13 and Technical Corrections" ("FASB 145") updates and clarifies certain existing accounting pronouncements. FASB Statements No. 4 and 64 require all gains and losses arising from the extinguishment of debt to be aggregated and classified as extraordinary items, net of tax effect. FASB No. 145 provides additional guidance in classifying gains and losses arising from the extinguishment of debt. FASB Statement No. 44 establishes accounting requirements for the effects of transition to the provisions of the Motor Carrier Act of 1980. Because the transition has been completed, FASB Statement No. 44 is no longer necessary. FASB Statement No. 145 amends FASB Statement No. 13 and requires that certain lease modifications that have economic effects similar to those of sale-leaseback transactions be accounted for in the same manner as sale-leaseback transactions. FASB 145 also makes a few technical corrections to existing pronouncements. FASB 145 is effective for transactions occurring after May 15, 2002. The adoption of FASB 145 by the Company did not have a material impact on the Company's financial position or results of operations.

Statement of Financial Accounting Standards No. 146, "Accounting for Costs Associated with Exit or Disposal Activities" ("FASB 146") addresses financial accounting and reporting for costs associated with exit or disposal activities. FASB 146 nullifies Emerging Issues Task Force Issue No. 94-3 because FASB 146 requires that liabilities assumed for costs associated with an exit or disposal activity be recognized when such liabilities are incurred rather than when the entity commits to an exit plan. FASB 146 is effective for transactions initiated after December 31, 2002. The adoption of FASB 146 by the Company is not expected to have a material impact on the Company's financial position or results of operations.

Statement of Financial Accounting Standards No. 147, "Acquisition of Certain Financial Institutions" (FASB "147") provides guidance on accounting for the acquisition of certain financial institutions. FASB 147 addresses and resolves inconsistencies between FASB Statements No. 72 and 142. The provisions of FASB 147 are effective after September 30, 2002. The adoption of FASB 147 by the Company is not expected to have a material impact on the Company's financial position or results of operations.

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

Total assets increased by $17.9 million, to $73.4 million during the nine-month period ended September 30, 2002. More specifically, cash and cash equivalents increased by $3.1 million, to $4.7 million; securities decreased by $1.8 million, to $11.3 million; and loans increased by $16.6 million, to $54.9 million. To fund the $17.9 million increase in assets, customer deposits were increased by $17.6 million, to $68.6 million, borrowings and other liabilities increased by $.1 million, to $.6 million, and capital accounts increased by $.2 million, to $4.2 million.

Liquidity and Sources of Capital

Liquidity is the Company's ability to meet all deposit withdrawals immediately, while also providing for the credit needs of customers. The September 30, 2002 financial statements evidence a satisfactory liquidity position as total cash and cash equivalents amounted to $4.7 million, representing 6.4% of total assets. Investment securities, which amounted to $11.3 million or 15.3% of total assets, provide a secondary source of liquidity because they can be converted into cash in a timely manner. The Bank is a member of the Federal Reserve System and maintains relationships with several correspondent banks and, thus, could obtain funds from these banks on short notice. The Company's management closely monitors and maintains appropriate levels of interest earning assets and interest bearing liabilities, so that maturities of assets can provide adequate funds to meet customer withdrawals and loan demand. The Company knows of no trends, demands, commitments, events or uncertainties that will result in or are reasonably likely to result in its liquidity increasing or decreasing in any material way. The Bank maintains an adequate level of capitalization as measured by the following capital ratios and the respective minimum capital requirements by the Bank's primary regulators.

|                                   | Bank'sSeptember 30, 2002 | Minimum RegulatoryRequirement
|---------------------------------- | ------------------------ | -----------------------------
|Leverage ratio
Risk weighted ratio | 6.3%
8.3%                | 4.0%
8.0%                    

With respect to the leverage ratio, the regulators expect a minimum of 5.0% to 6.0% ratio for banks that are not rated CAMELS 1. The Bank's leverage ratio of 6.3% and risk weighted ratio of 8.3% are above the required minimum. It is noted, however, that these two ratios are only slightly above the regulatory guidelines for adequately capitalized banks. Therefore, a capital injection may be necessary in the near future, especially if the Bank continues to grow at its current (2002) pace or if the Bank's asset mix changes materially from its current position.

Results of Operations

For the three-month period ended September 30, 2002, net income amounted to $71,807, or $.06 per diluted share. By comparison, net (loss) for the three-month period ended September 30, 2001 amounted to $(142,947), or $(.12) per diluted share. The reasons for the improvement in the results for the three-month period ended September 30, 2002 when compared to the three-month period ended September 30, 2001 are as follows:

1. Net interest income increased from $307,836 for the three-month period ended September 30, 2001 to $662,799 for the three-month period ended September 30, 2002. This increase is due to both higher average earning assets and a higher net interest yield.
2. Non-interest income for the three-month period ended September 30, 2002 was $57,941, an amount significantly higher than the $32,787 obtained during the three-month period ended September 30, 2001. The increase is due to higher transactional volume and higher fees.
3. Non-interest expense increased from $449,913 for the three-month period ended September 30, 2001 to $587,933 for the three-month period ended September 30, 2002. Despite this $138,020 increase in operating expense, non-interest expense as a percent of average assets declined from 4.74% to 3.65%, suggesting improved efficiencies.

Net income for the nine-month period ended September 30, 2002 amounted to $31,128, or $.03 per diluted share. For the nine-month period ended September 30, 2001, net (loss) amounted to $(513,599), or $(.45) per diluted share. The year-to-date results for the nine-month period ended September 30, 2002 represent the first positive year-to-date results since the Bank commenced operations. Below is a brief discussion concerning the Company's operational results for the nine-month period ended September 30, 2002, as compared to the nine-month period ended September 30, 2001.

a.	Interest income, which represents interest received on interest earning assets, increased from $2,053,467 for the nine-month period ended September 30, 2001 to $3,282,423 for the nine-month period ended September 30, 2002, an increase of $1,238,956. The cost of funds, which represents interest paid on deposits and borrowings, increased as well, from $1,175,774 for the nine-month period ended September 30, 2001 to $1,496,611 for the nine-month period ended September 30, 2002, an increase of $320,837. Because the growth in interest income during the nine-month period ended September 30, 2002 out-paced the increase in the cost of funds, net interest income grew from $877,693 for the nine-month period ended September 30, 2001 to $1,785,812 for the nine-month period ended September 30, 2002, an increase of $908,119.

-10-

Net interest yield, defined as net interest income divided by average interest earning assets, increased from 3.55% during the nine-month period ended September 30, 2001 to 3.89% during the nine-month period ended September 30, 2002. This increase is significant in light of the fact that the majority of financial institutions are experiencing a decline in the net interest yield caused primarily by the declining interest rate environment. Below is pertinent information concerning the yield on earning assets and the cost of funds for the nine-month period ended September 30, 2002.

(Dollars in '000s)

|Description                 | Avg. Assets/Liabilities | InterestIncome/Expense | Yield/Cost

|Net interest income         |                         | $1,786                 |           
|Net yield on earning assets |                         | 3.89%                 

b.	For the nine-month period ended September 30, 2002, non-interest income amounted to $171,591, or .34% of average assets. By comparison, non interest income for the nine-month period ended September 30, 2001 amounted to $78,831, or .29% of average assets. The majority of the increase (on a monetary basis) was caused by the increase in transactional account volume.

c.	For the nine-month period ended September 30, 2002, non-interest expense amounted to $1,751,730, or 3.48% of average assets. By comparison, for the nine-month period ended September 30, 2001, non interest expense amounted to $1,314,169, or 4.82% of average assets. This decrease (on a percentage basis) is primarily due to the improvement of operational efficiencies.

During the nine-month period ended September 30, 2002, the allowance for loan losses increased by $80,000, to $445,000. Despite the increase, however, the allowance for loan losses as a percentage of gross loans decreased from .94% at December 31, 2001 to .80% at September 30, 2002. Management considers the allowance for loan losses to be adequate and sufficient to absorb possible future losses; however, there can be no assurance that charge-offs in future periods will not exceed the allowance for loan losses or that additional provisions to the allowance will not be required.

Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its consolidated subsidiaries) that is required to be included in the Company's periodic filings with the Securities and Exchange Commission. There have been no significant changes in the Company's internal controls or, to the Company's knowledge, in other factors that could significantly affect those internal controls subsequent to the date the Company carried out its evaluation, and there have been no corrective actions with respect to significant deficiencies and material weaknesses.
