FOR IMMEDIATE RELEASE


                 BankFinancial Corporation Reports Net Income of
          $2.9 million, or $0.13 per Share for Fourth Quarter of 2005.


     Burr Ridge, Illinois - (March 1, 2006) BankFinancial  Corporation (Nasdaq -
BFIN)  ("BankFinancial") today reported net income of $2.9 million for the three
months ended  December 31, 2005,  and basic earnings per share of $0.13 for this
three-month period. For the year ended December 31, 2005, BankFinancial reported
net  income  of  $11.1   million,   and  basic  earnings  per  share  of  $0.29.
BankFinancial's  basic earnings per share for 2005 only reflect  earnings during
the period  after June 23,  2005,  the date of  BankFinancial's  mutual-to-stock
conversion, because no common shares were outstanding before then.

Overview

     Net income for the fourth  quarter of 2005 was $2.9  million,  compared  to
$3.7  million for the third  quarter of 2005.  Our third  quarter net income was
favorably  affected by two non-recurring  items - a tax recovery of $473,000 and
approximately  $150,000 in pre-tax  net  interest  income on stock  subscription
order  receipts  relating  to our  mutual-to-stock  conversion  that we refunded
during the third  quarter.  Our fourth  quarter  net income  included a $281,000
pre-tax  expense  relating  to  the  accelerated   amortization  of  a  purchase
accounting  adjustment resulting from the pre-payment of a loan that we acquired
in our  acquisition of Success  Bancshares.  We also increased our allowance for
loan and lease  losses  with a  provision  of  $524,000  in the  fourth  quarter
primarily to support loan growth,  compared to a $334,000 provision in the third
quarter.

     Net loans receivable  increased by $96.2 million during the fourth quarter.
We  maintained  our focus on deploying  conversion  proceeds  into targeted loan
categories such as multi-family real estate loans (an increase of $37.3 million,
or  15.4%),  commercial  leases (an  increase  of $29.6  million,  or 32.1%) and
commercial  loans (an  increase of $4.5  million,  or 6.9%).  This level of loan
growth was caused in part by seasonal and market factors and is not  necessarily
indicative  of future loan  growth.  Future loan growth  could also be adversely
affected by our  unwillingness  to compete for loans by relaxing our  historical
underwriting standards.

     Our allowance for loan and lease losses totaled $11.5 million at the end of
the fourth  quarter - an increase of  approximately  $583,000  primarily  due to
fourth  quarter  loan  growth -  representing  0.93% of total  loans and 201% of
nonperforming  loans. Our ratio of  nonperforming  loans to total loans declined
from 0.63% in the third quarter to 0.46% in the fourth quarter.

     We experienced  some net interest margin  compression in the fourth quarter
due to the flat yield curve and 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 4 basis points and yield
on earning assets  increased by 17 basis points - this increase was surpassed by
a 39 basis point  increase in our deposit costs.  As a result,  our net interest
margin  declined 4 basis points from 3.65% in the third  quarter to 3.61% in the

fourth  quarter,  and our net interest rate spread declined 16 basis points from
3.07% in the third  quarter  to 2.91% in the  fourth  quarter.  The  accelerated
purchase  accounting  adjustment  that we recorded in the fourth quarter reduced
our net interest rate spread by 7 basis points, while the net interest earned on
subscription  order  receipts in the third  quarter  added 4 basis points to our
third quarter net interest margin and interest rate spread.

     Our noninterest expense increased $119,000, or 1.0%, in the fourth quarter.
The increase was due in substantial part to increases in utility and real estate
tax expenses,  advertising expenses relating to deposit origination initiatives,
and information technology expenses relating to the design and implementation of
enhancements  to our corporate  performance  management  and reporting  systems.
Partially  offsetting  these  increases were declines in  consulting,  legal and
other expenses.

     Our net income was $11.1  million  for the year ended  December  31,  2005,
compared  to net  income  of $1.5  million  in 2004.  Our 2004  net  income  was
unfavorably  affected by  impairment  charges that we recorded on Fannie Mae and
Freddie Mac floating rate  preferred  stocks and yield  adjustment  amortization
expenses  resulting  from our  prepayment  of  certain  Federal  Home  Loan Bank
advances. Our mutual-to-stock conversion was completed on June 23, 2005, and our
financial  condition  and  results  of  operation  after that date  include  the
favorable  impact of the net  proceeds  of the  conversion.  Our 2005 net income
includes pre-tax compensation expenses in the amount of $718,000 relating to the
ESOP that we established in connection with the conversion.

     We  entered  into  an  agreement  during  the  fourth  quarter  to  acquire
University  National  Bank, a privately held community bank with $111 million in
assets  located  in the Hyde Park  community  of  Chicago.  The  transaction  is
presently scheduled to close in the second quarter of 2006. We expect University
National Bank's strong core deposit base and low loan to deposit ratio will help
mitigate future net interest margin compression pressures.
