                               BCSB BANKCORP, INC.
                         REPORTS MARCH 31, 2006 RESULTS

BCSB Bankcorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, reported earnings of $114,000 or $0.02 per basic and diluted
share for the quarter ended March 31, 2006. This compared to $96,000 or $0.02
per basic and diluted share for the same period in 2005, which represented an
increase of 18.8%. The increase in net income was attributed to a decrease in
non-interest expenses of $315,000, and an increase in non-interest income of
$44,000, partially offset by a decrease in net interest income of $336,000.

Net income decreased from $182,000 for the six months ending March 31, 2005 to a
net loss of ($5,000) for the six months ending March 31, 2006. Net income was
impacted by the decrease in net interest income of $719,000 from $8.1 million
for the six months ending March 31, 2005 to $7.4 million for the six months
ending March 31, 2006. The decrease was partially off-set by a decrease in
non-interest expenses and the decrease in the provision for loan losses. During
the six months ending March 31, 2006, the Company's assets decreased by $4
million or 0.5% from $812.7 million as of September 30, 2005 to $808.7 million
as of March 31, 2006.

President Gary C. Loraditch noted that earnings over the preceding six months
continued to be impacted by prevailing interest rates. However, the improved
quarterly results ending March 31, 2006 reflected the Bank's strategy to reduce
non-interest expenses and begin restructuring the Bank's balance sheet to reduce
the Bank's investment portfolio and to redirect cash flow into higher yielding
loan products. Interest income increased $963,000 or 10.8% from $8.9 million for
the three months ending March 31, 2005 compared to $9.9 million for the three
months ending March 31, 2006 and interest and fees on loans increased by $1.1
million or 18.9% from $5.9 million for the three months ending March 31, 2005 to
$7 million for the three months ending March 31, 2006. These increases reflected
an overall increase in the average balance of loans of $60.9 million from $398.3
million as of March 31, 2005 to $459.2 million as of the quarter ending March
31, 2006.
