Item 5. Other Events and Regulation FD Disclosure

On April 26, 2004, MFB Corp. and Sobieski Bancorp, Inc. ("Sobieski") jointly announced the signing of a definitive agreement pursuant to which MFB Financial, MFB Corp.'s federal savings association subsidiary, will acquire certain assets and assume certain liabilities (the "Acquisition") of Sobieski Bank, Sobieski's federal savings association subsidiary.

Under the terms of the agreement, MFB Financial will pay Sobieski Bank $1,026,682 (subject to certain adjustments). As of December 31, 2003, Sobieski Bank had approximately $110.5 million of assets and approximately $106.1 million of liabilities. Among items excluded from the Acquisition under the agreement are approximately $7.6 million (net book value after allowances and charge-offs as of January 31, 2004) of troubled and/or substandard assets, including certain commercial loans, real estate owned, assets seized in connection with litigation related to fraudulent activity affecting Sobieski Bank, and other items. These excluded assets are expected to be liquidated in an orderly manner, after which time Sobieski Bancorp will be liquidated and the net proceeds after expenses distributed to its shareholders. No assurance can be given that the excluded assets will be liquidated at or near their net book value after allowances and charge-offs.

The Acquisition is expected to close in the third quarter of 2004 subject to certain conditions, including the approval of the shareholders of Sobieski and the approval of regulatory authorities.

The agreement for the Acquisition is attached hereto as Exhibit 2 and is incorporated herein by reference.
