                               BCSB BANKCORP, INC.
                        REPORTS DECEMBER 31, 2005 RESULTS

BCSB Bankcorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, reported a net loss of $119,000 or ($0.02) per basic and
diluted share for the three months ended December 31, 2005. This compares to net
income of $86,000 or $0.01 per basic and diluted share for the same period in
2004. During the quarter, assets remained steady at $812.7 million at September
30, 2005 compared to $812.6 million as of December 31, 2005, while deposits
increased by $9.1 million or 1.5% from $597.7 million at September 30, 2005 to
$606.8 million at December 31, 2005. The increase in deposits was achieved
through normal marketing efforts and the opening of two new offices in Sparks
and Honeygo, Maryland. Earnings for the quarter were impacted by rising short
term rates both on borrowings and deposits which were not completely offset by
rising rates on loan products which generally have a longer term. Improvements
in spread should occur over time as long term rates continue to rise and funds
are re-invested in higher yielding assets and borrowings are reduced.

In light of reduced earnings resulting from the continued flat yield curve and
higher non-interest expenses, President Gary C. Loraditch announced that the
Board has adopted a number of strategies including a three year business plan
designed to enhance earnings. The strategies included increased operating
efficiencies, restructuring the Bank's balance sheet to reduce the Bank's
investment portfolio and redirect cash flow to higher yielding loan products and
leveraging the Bank's branch network by introducing additional products over the
upcoming years.

President Loraditch stated, "We want to capitalize on our traditional strength
as a solid residential community bank with a competitive product mix. During the
business plan process, we realized that we could consolidate several of our
operational departments utilizing new technologies provided by the Bank's data
processing conversion and still deliver the convenience and service for which
the Bank has been known." Interest income increased by $963,000 or 11.2% from
$8.6 million for the 3 months ended December 31, 2004 to $9.6 million for the 3
months ended December 31, 2005. Interest and fees on loans increased by $1.1
million or 19.2% from $5.6 million for the 3 months ended December 31, 2004 to
$6.7 million for the 3 months ended December 31, 2005. These increases were due
to an increase in the average balance of loans by $69.8 million from $387.4
million as of December 31, 2004 to $457.3 million as of December 31, 2005.

which was founded in 1955. The Bank currently operates eighteen offices
throughout the Baltimore metropolitan area. BCSB Bankcorp, Inc. became a
