Note 1 – Basis of Presentation

BankFinancial Corporation (the “Company”) completed its acquisition of DG Bancorp, Inc. and its wholly-owned subsidiary, Downers Grove National Bank on March 18, 2011. The acquisition was consummated through the merger of Kendachs Corporation, a wholly owned subsidiary of the Company, into DG Bancorp, Inc., and the merger of Downers Grove National Bank into the Company’s wholly-owned subsidiary, BankFinancial, F.S.B., in accordance with an Agreement and Plan of Merger dated as of September 13, 2010.

As a result of the mergers, each share of common stock of DG Bancorp, Inc. was converted into the right to receive approximately $37.16 in cash. The aggregate cash merger consideration was $3.27 million.

The acquired assets and assumed liabilities were measured at their estimated fair values, as required by the Financial Accounting Standards Board under standards governing Business Combinations (ASC 805-10). Management made significant estimates and exercised significant judgment in accounting for the acquisition. Among other things, management estimated the fair value of the loans acquired from Downers Grove National Bank based on loan file reviews (including borrower financial statements or tax returns), appraised collateral values, expected cash flows and historical loss factors. Other real estate acquired by Downers Grove National Bank through foreclosure was valued primarily on the basis of appraised collateral values. Management used quoted market prices to arrive at the fair value of investment securities. The Company recorded an identifiable intangible asset representing the estimated fair value of the core deposit base of Downers Grove National Bank based on management’s evaluation of the cost of such deposits relative to alternative funding sources. In conducting this evaluation, management used significant estimates, including estimates of the average lives of depository accounts, future interest rate levels and the cost of servicing various depository products.

Note 1 – Basis of Presentation (continued)

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed as of the date of the acquisition:

The Company has not completed the process of determining the acquisition date fair value of assets acquired and liabilities assumed, and the amounts disclosed above are considered provisional amounts. During the measurement period, the Company will retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new facts and information that existed at the acquisition date. The measurement period will end when the Company receives all of the information it is seeking about such facts and circumstances, and will not exceed one year from the acquisition date. Preliminary estimates of goodwill or bargain purchase gain were considered immaterial and thus were not recorded during the quarter ended March 31, 2011. Subsequent adjustments to the provisional amounts may be material.

The Company recorded an identifiable intangible asset associated with the acquisition consisting of a core deposit intangible. Identifiable intangible assets are amortized to their estimated residual values over their expected useful lives. The core deposit intangible is being amortized on a straight line basis over the expected useful life of such asset. The gross carrying amount of the core deposit intangible at March 31, 2011 was $2.7 million, and there was no accumulated amortization as of that date. The expected useful

lives of identifiable intangible assets are periodically reassessed to determine if any amortization period adjustments are required. No such adjustments were recorded during the quarter ended March 31, 2011,

The unaudited pro forma condensed combined statement of financial condition as of December 31, 2010 and the unaudited pro forma condensed combined statement of operations for the year then ended have been prepared to reflect the business combination as if the Company’s acquisition of DG Bancorp, Inc. had occurred on December 31, 2010 with respect to the pro forma combined statement of financial condition, and had occurred on January 1, 2010 with respect to the pro forma combined statement of operations. Both pro forma financial statements reflect the pro forma adjustments that are described in the accompanying notes.

The unaudited pro forma condensed combined pro forma statement of operations is not necessarily indicative of the results of operations that would have occurred if the acquisition had been effective as of January 1, 2010, or the Company’s future results. Pro forma adjustments have been limited to those directly attributable to the acquisition. The pro forma combined financial statements should be read in conjunction with the historical consolidated financial statements and related notes of the Company and DG Bancorp, Inc.
