PRESS RELEASE CENTRAL BANCORP REPORTS QUARTERLY EARNINGS SOMERVILLE, MASSACHUSETTS, July 26, 2006 - Central Bancorp, Inc. (NASDAQ Global MarketSM:CEBK) today reported that its net income for the quarter ended June 30, 2006 was $113,000, or $0.08 per diluted share. For the corresponding quarter in the prior fiscal year, the Company reported net income of $706,000, or $0.49 per diluted share. The decrease in net income for the quarter ended June 30, 2006 compared to the quarter ended June 30, 2005 was primarily the result of a decrease in net interest and dividend income from $4.2 million for the 2005 quarter to $3.6 million for the 2006 period, a $4 thousand decrease in non-interest income and an increase in non-interest expense from $3.5 million to $3.8 million, partially offset by a $323,000 decrease in the provision for income taxes. The decrease in net interest and dividend income is primarily the result of the combined effect of a decrease in net interest spread and net interest margin and, to a lesser extent, the postponement of the dividend on our investment in stock in the Federal Home Loan Bank. Decreases occurred in the net interest spread and the net interest margin from 2.88% and 3.23%, respectively, for the quarter ended June 30, 2005 to 2.29% and 2.72%, respectively, for the quarter ended June 30, 2006. The decreases in the spread and margin were primarily due to increases in both the volume and the rates paid on interest-bearing liabilities. While the cost of funds increased by 57 basis points, the yield on interest-earning assets declined by 2 basis points. Interest-bearing liabilities repriced upward faster than interest-earning assets primarily due to the increase in short-term interest rates and the flat yield curve, as well as our continued offering of promotional rates on certificates of deposit due to increased competition for deposit accounts in our market. The decrease in interest income is primarily the result of the Federal Home Loan Bank's postponement of its quarterly dividend because of restrictions in its new capital guidelines. During the quarter ended June 30, 2005, the FHLB's dividend totaled $88 thousand; we expected the dividend to exceed $100,000 in the quarter ended June 30, 2006. We have been advised that the FHLB expects to declare a six-month equivalent dividend during the quarter ending September 30, 2006. Increases in non-interest expense reflected normal salary and benefit increases as well as added staff for our new branch and rent, utilities and equipment for the new branch and operations center. Marketing expense also increased from the comparable period last year. Total interest and dividend income increased from $7.4 million for the three-months ended June 30, 2005 to $7.5 million for the current year period, primarily as a result of a $16.9 million, or 4.3%, increase in the average balance of loans from June 30, 2005 to June 30, 2006. Loans increased primarily as a result of an increase in the origination of commercial real estate loans, which increased mainly due to our continued focus on originating these loans. Loans decreased $3.1 million from March 31, 2006 to June 30, 2006 primarily as a result of a net decline in commercial real estate and construction loans of $1.5 million and residential loans of $2.9 million, partially offset by an increase in loans held for sale of $0.3 million and other loans of $1.0 million. Total assets were $545.5 million at June 30, 2006 and $547.3 million at March 31, 2006. During the three months ended June 30, 2006, investment securities available for sale decreased by $12.0 million as the result of maturities and pay-downs of investments and the mandatory redemption of a portion of our investment in FHLB stock. This decline was offset by an increase in short-term investments of $10.6 million. Liabilities decreased from $508.1 million at March 31, 2006 to $506.5 million at June 30, 2006, primarily due to a decrease in borrowings of $16.7 million offset by an increase in deposits of $15.5 million. Borrowings decreased as we used deposit growth to pay down maturing and called borrowings at lower replacement rates. Deposits increased to $408.9 million at June 30, 2006 from $393.4 million at March 31, 2006. The increase in deposits occurred primarily in certificates of deposit and as a result of our offering of promotional rates on these accounts and, to a lesser extent, due to the opening of our new Medford office. The provision for loan losses was $50,000 for the quarters ended June 30, 2006 and June 30, 2005. Management considered the allowance for loan losses to be adequate during both periods. Non-interest income decreased $4,000 for the quarter ended June 30, 2006 compared to the 2005 period, primarily as a result of the $22,000 decrease in gain on sales of loans due to a slower residential real estate environment, offset by an increase in deposit account related fees of $24,000. Non-interest expense was $3.8 million in the June 2006 quarter compared to $3.5 million for the prior year quarter primarily due to staffing and occupancy costs associated with the opening of our new branch office and operations center as well as infrastructure improvements. Income tax expense for the June 2006 quarter decreased $323,000 from the 2005 quarter due to the decrease in pre-tax income. In June we opened our new Medford branch. We are pleased with the results to date and with the reception we have received in the community.
