                       FIRST QUARTER 2006 FINANCIAL REVIEW


     BankFinancial  Corporation (Nasdaq - BFIN)  ("BankFinancial")  reported net
income of $3.1 million,  or $0.14 per common  share,  for the three months ended
March  31,  2006,  compared  to $2.9  million,  or $0.13 per share for the three
months ended December 31, 2005 and $1.6 million for the three months ended March
31,  2005.  Earnings per share was not reported for the three months ended March
31, 2005 because  BankFinancial  had no common shares  outstanding prior to June
23, 2005.

Overview

     Net income for the first quarter of 2006 was $3.1 million, compared to $2.9
million for the fourth  quarter of 2005,  and $1.6 million for the first quarter
of 2005.  Our first  quarter  net income  included a $476,000  pre-tax  gain and
$106,000  in fees  relating  to the sale of surplus  property,  and  reflected a
$196,000 provision for loan losses to support loan growth.

     Net loans receivable increased by $29.9 million, or 2.4%, to $1.262 billion
at March 31,  2006,  from $1.232  billion at December  31,  2005.  The  increase
resulted  primarily from increased  originations  in targeted loan categories in
anticipation of our pending acquisition of University National Bank and our plan
to convert a substantial part of its portfolio of lower-yielding securities into
higher-yielding  loans.  Commercial  leases  increased  $6.2  million,  or 5.1%.
Multi-family  mortgage loans  increased $9.1 million,  or 3.3%.  Non-residential
real estate loans  increased  $7.1  million,  or 2.6%,  and  construction  loans
increased $5.1 million, or 6.3%. One- to four-family  residential mortgage loans
increased by $4.0 million, or 1.0%.

     Due to the $29.9 million in net loan growth, we increased our allowance for
performing loans by $228,000.  Our allowance for impaired loans remained at $1.8
million,  decreasing  by a net of $32,000  from  December  31,  2005.  Our total
allowance  for loan and lease  losses was $11.7  million at March 31,  2006,  or
0.92% of total loans and 367% of nonperforming loans, compared to 0.93% of total
loans and 201% of nonperforming loans at December 31, 2005.  Nonperforming loans
continued to decline, decreasing from $5.7 million at December 31, 2005, to $3.2
million at March 31, 2006.  Nonperforming loans represented 0.25% of total loans
at March 31, 2006, compared to 0.46% of total loans at December 31, 2005.

     Total deposits decreased slightly from $1.068 billion at December 31, 2005,
to  $1.053  billion  at March  31,  2006,  due in part to the  unusually  strong
seasonal  deposit  growth  that  occurred  late in the  fourth  quarter of 2005,
followed by deposit  outflows in the first quarter of 2006.  Total core deposits
(savings,  money market,  noninterest  bearing demand and NOW accounts) remained
relatively stable as a percentage of total deposits, representing 66.1% of total
deposits at March 31, 2006,  compared to 67.2% of total deposits at December 31,
2005.

     Our  borrowings  increased  $44.9 million,  or 23.4%,  to $236.3 million at
March 31,  2006,  from $191.4  million at December  31,  2005.  The increase was
temporary in nature, as we used the additional  borrowings  primarily to provide
short-term  funding for targeted loan growth in  anticipation of the closing our
acquisition  of  University  National Bank and our plan to convert a substantial
part of its  securities  portfolio  into  higher-yielding  loans.  We closed the
acquisition on April 5, 2006, and sold  approximately  $54 million of University
National Bank's investment  securities.  We used the net proceeds of the sale of
the securities to repay short-term borrowings.

We continued to experience slight net interest margin compression due to the flat yield curve and the highly competitive loan and deposit pricing in the Chicago banking market. Although the loan growth that we experienced improved interest income - yields on loans increased by 16 basis points and yield on earning assets increased by 18 basis points - this increase was surpassed by an 18 basis point increase in our deposit costs and a 23 basis points increase in our cost of borrowings. As a result, our net interest rate spread declined four basis points from 2.91% in the fourth quarter of 2005 to 2.87% in the first quarter, and our net interest margin declined by one basis point from 3.61% in the fourth quarter to 3.60% in the first quarter. Our noninterest income increased $221,000, or 8.7%, to $2.8 million for the first quarter of 2006 compared to $2.5 million for the fourth quarter of 2005. Noninterest income for the first quarter included a $476,000 pre-tax gain and $106,000 in fees relating to the sale of surplus property. Noninterest expense increased 1.0%, or $118,000, from $11.5 million in the fourth quarter of 2005 to $11.6 million in the first quarter of 2006. Compensation expense increased primarily due to increased ESOP expenses and seasonally higher employee taxes totaling $183,000. University National Bank Acquisition On April 5, 2005, we acquired University National Bank, a privately held community bank with $110 million in assets and $101 million in deposits as of March 31, 2006, and two banking offices in the Hyde Park community in Chicago, Illinois, for approximately $24 million in cash pursuant to the terms of a Stock Purchase Agreement with University Bancorporation dated November 29, 2005. Immediately upon the completion of the stock purchase, University National Bank was merged into BankFinancial, F.S.B. The transaction will be treated, for federal and state income tax purposes, as a purchase of University National Bank's assets pursuant to applicable provisions of the Internal Revenue Code, making the goodwill and core deposit intangible arising from the transaction tax-deductible over a period of 15 years. Cash Dividend On March 30, 2006, the Board of Directors declared our first cash dividend on our common stock in the amount of $0.06 per share. This dividend will be payable on May 19, 2006 to stockholders of record as of May 3, 2006.
