                               BCSB BANKCORP, INC.
                        REPORTS RESULTS OF JUNE 30, 2004

BCSB Bankcorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, recorded earnings of $233,000 or $0.04 per share for the
quarter ending June 30, 2004. This compared to $22,000 or $0.00 per share for
the same period in 2003. The increase in net income was primarily attributed to
a decrease in the provision for loan losses, partially offset by an increase in
non-interest expenses and a decrease in non-interest income for the same period
in 2003. Net interest income remained relatively constant at $4.1 million for
the three months ending June 30, 2004 compared to $4.2 million for the three
months ending June 30, 2003. Interest income increased from $8.2 million for the
three months ending June 30, 2003 to $8.3 million for the three months ending
June 30, 2004. For the nine months ending June 30, 2004, total assets equaled
$750 million as compared to $668 million on September 30, 2003, an increase of
$82 million. Total deposits rose to $582 million as of June 30, 2004, compared
to $552 million on September 30, 2003.

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