                               BCSB BANCORP, INC.
              REPORTS RESULTS FOR QUARTER ENDING DECEMBER 31, 2008

BCSB Bancorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, FSB, reported net income of $240,000 or $0.08 per basic and
diluted share for the three month period ended December 31, 2008, which
represents the first quarter of its 2009 fiscal year. This compares to net
income of $93,000 or $0.03 per basic and diluted share for the three months
ended December 31, 2007.

During the three months ending December 31, 2008, the Company benefited from
increases in net interest income, non-interest income and decreased non-interest
expense as compared to the corresponding period during the prior fiscal year.
These improvements in earnings were partially offset by $150,000 in loan loss
provisions during the three months ending December 31, 2008 to address continued
declines in economic conditions, particularly in relation to the local real
estate market.

President and Chief Executive Officer Joseph J. Bouffard commented that "The
Company continues to make progress in its efforts to improve profitability and
enhance shareholder value in these difficult economic times. The $10.8 million
capital infusion related to the U.S. Treasury's TARP Capital Purchase Program
provided additional liquidity to help our customers manage through these
difficult economic times as well as support the Company's other long term
initiatives." He also noted that the Bank's lending portfolio continues to be a
strength of the Company. The ratio of nonperforming assets to total assets
improved from 0.49% at December 31, 2007 to 0.22% at December 31, 2008.

Stockholders' equity increased by $9.6 million during the quarter ending
December 31, 2008. This reflects the Company's aforementioned TARP proceeds
received in December 2008 as well as earnings during the period. Stockholders'
equity was negatively impacted by accumulated other comprehensive loss (net of
taxes) which was ($3.9) million at December 31, 2008 compared to ($2.5) million
at the end of the previous quarter. Most of this loss relates to the Company's
$24.6 million in collateralized mortgage obligation securities portfolio, for
which the gross market value declined by $4.0 million during the most recent
quarter. This is reflective of turmoil in the mortgage backed securities market
and the price decline in market value of these securities. The Company has the
ability and the intent to hold these securities to maturity and to date, the
securities have performed in accordance with their terms. If in the future it is
determined that declines in market values with respect to these or any other
securities are other than temporary, the Company would be required to recognize
losses in its Consolidated Statement of Operations. The Company has no equity
holdings in Federal Home Loan Mortgage Corporation or Federal National Mortgage
Association stock and, accordingly, has no loss exposure in this area.
