                                  PRESS RELEASE
                    FOR RELEASE OCTOBER 22, 2008 AT 4:00 P.M.

                          For More Information Contact
                      Joseph J. Bouffard, President and CEO
                                 (410) 248-9130
                               BCSB Bancorp, Inc.

              BCSB BANCORP, INC. REPORTS RESULTS FOR THE YEAR ENDED
                               SEPTEMBER 30, 2008

BCSB Bancorp, Inc. (NASDAQ: BCSB), the holding company for Baltimore County
Savings Bank, F.S.B., headquartered in Baltimore, Maryland, reported net income
of $894,000 or $0.30 per basic and diluted share for the year ended September
30, 2008, as compared to a net loss of $2.9 million or ($0.95) per basic and
diluted share for the year ended September 30, 2007. For the three months ended
September 30, 2008, net income was $461,000 or $0.16 per basic and diluted share
as compared to a net loss of $307,000 or ($0.11) per basic and diluted share for
the three months ended September 30, 2007.

During the three and twelve months ended September 30, 2008, the Company
benefited from increases in net interest income and non-interest income as
compared to corresponding periods in the prior fiscal year. These improvements
to earnings were partially offset by $360,000 in loan loss provisions during the
three months ended September 30, 2008 to address the continued decline in
economic conditions, particularly in relation to the local real estate market.

The loss for the year ended September 30, 2007 was primarily associated with the
balance sheet restructuring completed by the Company in March of 2007. In
conjunction with this restructuring, the Company realized pre-tax losses of $7.1
million from the sale of investments and loans. Also during the year ended
September 30, 2007, the Bank received $3.4 million in insurance proceeds as a
partial recovery of losses incurred resulting from a check-kiting fraud
perpetrated against the Bank in June of 2006.

The $307,000 loss for the quarter ended September 30, 2007 was due to $296,000
of expenses related to the check-kiting scheme previously discussed and
additional compensation expenses of approximately $150,000 related to an
agreement with a member of the executive management team, who retired after 34
years of service. In addition, professional fees of approximately $150,000 were
incurred for special, limited scope consulting and legal projects.

Stockholders' equity increased by $15.2 million during the year ended September
30, 2008. This reflects the Company's increased earnings as well as its
successful capital raising efforts. Stockholders' equity was negatively impacted
by accumulated other comprehensive loss (net of taxes) which was ($2.5) million
at September 30, 2008 compared to ($1.6) million at the end of the previous
quarter. Most of this loss relates to the Company's $25.1 million in
collateralized mortgage obligation securities portfolio, for which the gross
market value declined by $1.1 million in the most recent quarter and $3.7
million in the last six months. This is reflective of turmoil in the mortgage
backed securities market and the price drop in the 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.

President and CEO Joseph J. Bouffard commented that he was very pleased with
progress made over the past fiscal year despite unprecedented challenges within
the industry. The Company was successful in achieving its three major
initiatives for the year, which were to raise capital, have a regulatory
supervisory agreement rescinded and become profitable. During the year, the
Company converted to a fully publicly traded company. As a result of the
conversion, capital ratios were strengthened and debt was reduced at both the
Bank and the holding company. Earlier in the year, in recognition of the
Company's improvements, the Bank's principal regulator, the Office of Thrift
Supervision, rescinded a Supervisory Agreement that had been in effect since
2005. The Company has also enjoyed four consecutive quarters of profitability.
On a cautionary note Bouffard noted that loan charge-offs increased during the
three months ended September 30, 2008. And although nonperforming loans have
declined recently, future additions to the loan loss reserve may be necessary if
economic conditions deteriorate further.

               FISCAL YEAR ENDED SEPTEMBER 30, 2008 HIGHLIGHTS

o     Raised nearly $20 million by completing conversion from Mutual Holding
      Company structure to a fully publicly owned corporation.

o     Net interest income for the year increased by more than $1.2 million or
      8.9% compared to 2007.

o     Paid off more than $16 million in debt, including $6 million in Trust
      Preferred Securities.

o     Interest  rate spread for 2008  improved to 2.60% from 2.04% in 2007,  a
      27% increase over the prior year.

o     Allowance for loan losses to nonperforming loans increased to 320% in 2008
      from 116% in 2007.

o     Equity to assets ratio at September  30, 2008 improved to 8.8% from 5.4%
      at September 30, 2007.
