                               BCSB BANKCORP, INC.
              REPORTS RESULTS FOR QUARTER ENDING DECEMBER 31, 2006

BCSB Bankcorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, reported a net loss of $233,000 or ($0.04) per basic and
diluted share for the three months ending December 31, 2006. This compares to a
net loss of $119,000 or ($0.02) per basic and diluted share for the same period
in 2005. 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 longer terms.

President and Chief Executive Officer Joseph J. Bouffard announced that the
Board is adopting a number of strategies to enhance earnings. "Our initial
emphasis will be on increasing the Bank's net interest margin by enhancing the
Bank's loan production and reviewing the Bank's deposit structure," said
Bouffard. The initiatives will also include improving non-interest income by
more effectively utilizing the Bank's branch network to generate additional fee
income, he added.

BCSB Bankcorp, Inc. is the holding company of Baltimore County Savings Bank, FSB
which was founded in 1955. The Bank currently operates eighteen offices
throughout the Baltimore metropolitan area. BCSB Bankcorp, Inc. became a
publicly traded mutual holding company in July 1998.
