                 MFB Corp. ANNOUNCES FIRST QUARTER EARNINGS AND
                          QUARTERLY DIVDEND DECLARATION

Mishawaka, Indiana - MFB Corp. (NASDAQ/MFBC), parent company of MFB Financial
(the "Bank"), reported today its consolidated financial results on an unaudited
basis of $1.2 million, or $0.84 diluted earnings per share for the three months
ended December 31, 2006 an increase from the net loss of $397,000 or $0.29
diluted loss per share, for the three months ended December 31, 2005.

Charles J. Viater, President and CEO, stated "The Bank benefited this quarter
from the recovery of loan losses and a partial settlement from the WorldCom
class action law suit. Despite the challenging rate environment, we remain
focused on the continued growth of loans and deposits."

In addition, Mr. Viater announced today that the Board of Directors has declared
a cash dividend of $0.165 per share of common stock for the quarter ended
December 31, 2006. The dividend is payable on February 13, 2007 to holders of
record on January 30, 2007.


MFB Corp's net interest income before provision for loan losses for the three
month period ended December 31, 2006 was $3.1 million compared to $3.5 million
for the same period last year. The decrease was primarily due to an increase in
interest expense on deposits partially offset by a reduction of FHLB advances
and other borrowings interest expense. Interest expense on deposits increased to
$2.6 million for the quarter ended December 2006 compared to $2.1 million for
the quarter ended December 2005, while expense for borrowings declined to $1.5
million from $1.6 million for the comparable periods. Total interest income
earned was $7.1 million for the quarter ended December 2006 and $7.2 million for
the same quarter in 2005.

MFB recorded a recovery of loan losses of $1.1 million for the quarter ended
December 31, 2006 compared to a provision of $2.1 for the same period last year.
The recovery during the quarter ended December 31, 2006 was predominantly
related to the repayment of two commercial loans which previously had
significant allowance for loan losses allocations. The provision during the
first quarter ended December 31, 2005 was primarily related to management's
assessment of a commercial loan (which is the larger of the two loans discussed
above) to a business experiencing difficulties with inventory management, trade
accounts receivable collections, financial reporting, and operating cash flow.
This loan is primarily secured by inventory and accounts receivable. During the
first quarter ended December 31, 2005, the Bank updated the analysis of the
value of this collateral, completed an assessment of the reliability and
adequacy of accounting systems and evaluated the most recent financial
performance of the business and determined that an additional charge to earnings
in the amount of $2.3 million ($1.4 million net of tax) for this loan was
necessary. The percentage of non-performing assets to total loans decreased from
2.18% at September 30, 2006 to 1.90% at December 31, 2006.

Noninterest income totaled $1.6 million for both quarters ending December 31,
2006 and 2005. In the quarter ended December 31, 2006, MFB recorded a gain on
securities of $361,000 as a partial settlement on a WorldCom class action suit;
an impairment of $49,000 was recorded for the valuation of mortgage servicing
assets in the current quarter while in the prior year period a recovery of
$167,000 was recorded for the valuation of mortgage servicing rights.

Noninterest expense increased to $4.2 million for the quarter ended December 31,
2006 from $3.9 million for the quarter ended December 31, 2005. The increase was
primarily from increased salaries and employee benefits as well as an increase
in marketing and business development expenses.

The Company's total assets were $501.9 million as of December 31, 2006 compared
to $496.1 million as of September 30, 2006. Cash and cash equivalents increased
from $16.3 million at September 30, 2006 to $21.7 million at December 31, 2006.
As of December 31, 2006 total securities available for sale were $53.0 million,
a decrease of $5.4 million from $58.4 million at September 30, 2006.

Loans receivable increased from $379.2 million at September 30, 2006 to $383.3
million at December 31, 2006. Mortgage loans increased by $900,000 from $199.2
million at September 30, 2006 to $200.1 million at December 31, 2006. Commercial
loans outstanding increased slightly from $134.4 million at September 30, 2006
to $134.9 million at December 31, 2006. Consumer loans, including home equity
and second mortgages, increased by $2.6 million during the three month period.

During the first quarter ended December 31, 2006, the Company completed
secondary market mortgage loan sales totaling $2.1 million and the net gains
realized on these loan sales were $51,000 including $26,000 related to recording
mortgage servicing rights. During the quarter ended September 30, 2006, the
Company completed secondary market mortgage loan sales totaling $2.3 million and
the net gains realized on these loan sales were $49,000 including $29,000
related to recording mortgage servicing rights.

The allowance for loan losses at December 31, 2006 was $5.7 million or 1.48% of
loans compared to $7.2 million or 1.91% of loans at September 30, 2006. For the
first quarter ended December 31, 2006, net charge-offs were $439,000 compared to
$37,000 net charge-offs for the quarter ended September 30, 2006.

Total liabilities increased by $4.8 million, from $457.1 million at September
30, 2006 to $461.9 million at December 31, 2006. The bank's noninterest-bearing
demand deposits increased $3.2 million, and time deposits increased $3.2
million; and were offset in part by a decrease in savings and NOW deposits of
$1.9 million. Advances from the FHLB increased slightly to $98.0 million at
December 31, 2006, from $97.1 million at September 30, 2006.
