ITEM 1.01     ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT
              ------------------------------------------

         On January 25, 2007 Central Bancorp, Inc. (the "Company") entered into
an agreement, subject to the financing arrangement discussed below and other
conditions, to purchase 109,600 shares of the Company's common stock at a price
of $33.00 per share from Mendon Capital Advisors Corp. and affiliates
(collectively, "Mendon"). The shares to be purchased by the ESOP represent
approximately 6.7% of the Company's outstanding shares. After the purchase, the
ESOP will hold approximately 24.9% of the Company's outstanding shares,
including shares allocated to participants. Separately, John D. Doherty, the
Company's President and Chief Executive Officer, agreed, also subject to
conditions, to purchase the remaining 13,400 shares of the Company's common
stock owned by Mendon, also at a price of $33.00 per share, which purchase
facilitates the ESOP's purchase.

         Completion of the purchase is subject to the issuance by the Company of
approximately $6 million of trust preferred securities to finance, through loans
to the ESOP, the ESOP's purchase of the shares from Mendon and its refinance of
an existing loan from an independent financial institution used to fund a
previous purchase of the Company common stock. The agreement also includes a
provision restricting Mendon or any of its affiliates from knowingly acquiring
or offering to acquire shares of the Company's securities, either directly or
indirectly, for a period of five years following the closing of the transaction
without the prior written approval of the Company's Board of Directors.

         A copy of the Stock Purchase Agreement dated January 25, 2007 is
attached to this Report as Exhibit 99.1 and incorporated herein by reference.
Additionally, a press release announcing the transaction is attached to this
Report as Exhibit 99.2 and furnished herewith.

II of the Company's Bylaws to opt out of the control share acquisition
provisions set forth in Title XV, Chapter 110D of the Massachusetts General

Report as Exhibit 3.1 and incorporated herein by reference.
