              AMB FINANCIAL ANNOUNCES AN INCREASE IN THE QUARTERLY
                       DIVIDEND AND FIRST QUARTER RESULTS

Munster, Indiana - AMB Financial Corp. (OTCBB: AMFC) (the "Company") the parent
holding company for American Savings, FSB (the "Bank") announced today that
earnings per share for the first quarter ended March 31, 2005 totaled $.14 per
diluted share, compared to $.26 per diluted share reported for the quarter ended
March 31, 2004. The decreased earnings per share compared to last year resulted
primarily from a higher loan loss provision as well as the reporting of an
unrealized loss from the Company's trading portfolio compared to an unrealized
gain reported in the prior year period. Net income for the current quarter
totaled $144,000 compared to $265,000 reported in the year earlier period.
Return on average equity and return on average assets were 4.24% and .37%,
respectively, in the current quarter compared to 8.29% and .72% in last year's
comparable period.

AMB Financial Corp. also announced an increase in its quarterly cash dividend to
$.07 per share for the quarter ending March 31, 2005, an increase of 16.67% from
the $.06 per share paid for the prior quarter. The dividend will be payable on
May 25, 2005 to the shareholders of record on May 11, 2005.

RESULTS FOR THE QUARTER ENDED MARCH 31, 2005

Net interest income for the current quarter totaled $1.13 million, up slightly
from the $1.12 million for last year's first quarter. The Bank's net interest
margin was 3.23% in the current quarter, compared to 3.39% in the March 31, 2004
quarter. The decline in the net interest margin was primarily due to a decline
in the yield on interest-earning assets to 5.73% in the current quarter compared
to 5.93% in last year's first quarter. This decrease resulted primarily from the
impact of loan prepayments, with new loans originating at lower rates as well as
the acceleration of amortization of premium write-off on purchased loans. The
lower asset yields were partially offset by a decline in funding costs as the
average cost of interest-bearing liabilities decreased to 2.53% in the current
quarter from 2.56% in last year's comparable quarter.

Non-interest income decreased to $271,000 in the current quarter, compared to
$352,000 reported in last year's first quarter. The decline in non-interest
income was primarily attributable to a $68,000 decrease in income from trading
account securities as the market price of the Company's portfolio of small
thrift and community bank stocks declined primarily due to a general decline in
financial institution stock prices during the quarter. In addition, the prior
year period includes a $27,000 gain from the excess proceeds on a life insurance
policy due to the death of one of the Company's directors. Offsetting these
decreases in non-interest income was a $12,000 increase in deposit related fees,
primarily due to a new fee structure on NOW account overdrafts and higher ATM
surcharge fees as well as an increase of $17,000 in service fee income related
to the Company's accounts receivable, serviced by others, which experienced an
increase in activity between the periods. The Company also incurred a loss of
$22,500 in the current quarter compared to a loss of $21,500 in prior year's
quarter, related to an investment in a low-income housing joint venture. As a
result of this investment, the Company recorded an offsetting $35,000 in federal
income tax credits during both periods, which resulted in the reduction of the
Company's effective income tax rate.

In March 2005, the shareholders of Intrieve, Incorporated, the Bank's data
processing provider, approved the sale and merger of Intrieve into Harland
Financial Solutions, Inc., a wholly owned subsidiary of John H. Harland Company.
This transaction closed in April 2005. As a shareholder of Intrieve, the Bank
received $344,000 in cash on its $15,000 investment, resulting in a gain of
$329,000, which will be recorded in the second quarter of 2005.

Non-interest expense totaled $1.06 million in the current quarter; a decline of
$9,000 from the $1.07 million reported for the quarter ended March 31, 2004. The
decrease resulted from a reduction in



advertising costs of $25,000 as well as a decline in real estate tax and
depreciation expense of $15,000. These decreases were offset by increases in
staffing costs of $5,000, primarily increased benefit costs, increased data
processing costs of $9,000 and increased professional fees of $14,000 due to
ongoing regulatory compliance efforts and increased examination fees.

The Company recorded a provision for loan losses of $154,000 during the
three-month period ended March 31, 2005 as compared to a $26,000 provision in
the prior year period. There were no changes in estimation method or assumptions
that impacted the provision for loan losses during the quarter. During the
current quarter, the Company's management, based upon updated information,
authorized the establishment of $105,000 of additional reserves against three
non-accrual loans including two related purchased commercial business loans
secured by medical equipment having a net book value at December 31, 2004 of
$72,000 and one unsecured loan to an unrelated borrower having a net book value
at December 31, 2004 of $33,000. At March 31, 2005, as a result of these
reserves, the subject loans had no remaining net book value. These loans were
charged off in April 2005. The Bank's general allowance for loan losses was
$658,000 at March 31, 2005, which is equal to 37.8% of non-performing loans and
..50% of net loans receivable.

Income tax expense totaled $40,000 in the current quarter, an effective tax rate
of 21.9%, compared to $103,000 or an effective tax rate of 28.0% for the quarter
ended March 31, 2004. Both periods were positively impacted by the recognition
of approximately $35,000 in low-income housing tax credits, which have a greater
impact on the effective rate in a lower earnings period compared to a higher
earnings period.

BALANCE SHEET AND CAPITAL

Total assets of the Company increased by $3.2 million to $160.3 million at March
31, 2005 from $157.1 million reported at December 31, 2004. The increase in
assets during the three-month period resulted primarily from growth in loan
balances, which totaled $132.3 million at March 31, 2005 compared to $129.3
million at December 31, 2004, an increase of $3.0 million. In addition, the
Company increased its cash position by $400,000 at March 31, 2005. The growth in
assets during the three-month period was funded primarily from an increase in
borrowed money, which increased by $2.0 million to $21.0 million at March 31,
2005. Deposit balances also increased slightly to $116.0 million at March 31,
2005 from $115.7 million at December 31, 2004.

As of March 31, 2005, stockholders' equity in AMB Financial Corp. totaled $13.3
million. The number of common shares outstanding at March 31, 2005 was 974,143
and the book value per common share outstanding was $13.69. The Bank's tangible,
core and risk-based capital percentages of 9.02%, 9.02% and 15.33%,
respectively, at March 31, 2005 exceeded all regulatory requirements by a
significant margin.

Non-performing assets increased during the past three months totaling $1.95
million or 1.22% of total assets at March 31, 2005 compared to $1.61 million or
1.02% of total assets at December 31, 2004. The increase in the most recent
three-month period relates to several delinquent single-family residential
loans. One of these loans, amounting to $106,000 at March 31, 2005, has since
been brought current.
