ITEM 2.03   CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
            OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT

         On  September  16,  2004,  Central  Bancorp,  Inc.  (the  "Registrant")
completed a trust preferred  securities financing in the amount of $5.1 million.
In the transaction,  the Registrant formed a Delaware  statutory trust, known as
Central  Bancorp  Capital Trust I (the "Trust").  The Trust issued and sold $5.1
million of trust preferred securities in a private placement and issued $158,000
of trust common  securities  to the  Registrant.  The Trust used the proceeds of
these issuances to purchase $5,258,000 of the Registrant's  floating rate junior
subordinated debentures due September 16, 2034 (the "Debentures").  The interest
rate on the  Debentures  and the trust  preferred  securities  is  variable  and
adjustable  quarterly at 2.44% over  three-month  LIBOR.  The Debentures are the
sole assets of the Trust and are subordinate to all of the Registrant's existing
and future  obligations  for  borrowed  money.  The trust  preferred  securities
generally rank equal to the trust common securities in priority of payment,  but
will rank prior to the trust common  securities if and so long as the Registrant
fails to make  principal or interest  payments on the  Debentures.  Concurrently
with the issuance of the  Debentures  and the trust  preferred  securities,  the
Registrant issued a guarantee related to the trust securities for the benefit of
the holders.

         The Debentures  and the trust  preferred  securities  each have 30-year
lives.  The trust preferred  securities and the Debentures will each be callable
by the Registrant or the Trust, at their respective option after five years, and
sooner in certain  specific  events,  including in the event that the securities
are not eligible for treatment as Tier 1 capital,  subject to prior  approval by
the Federal  Reserve Board,  if then required.  Interest on the trust  preferred
securities  and the  Debentures may be deferred at any time or from time to time
for a period not  exceeding 20  consecutive  quarterly  payments  (five  years),
provided there is no event of default.


ITEM 5.02   DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF DIRECTORS;
            APPOINTMENT OF PRINCIPAL OFFICERS.

         Effective September 17, 2004,  Directors Richard J. Lashley and Richard
J. Fates  resigned  from the Boards of Directors of the  Registrant  and Central
Co-operative Bank (the "Bank"),  and all committees of such Boards on which they
served. In connection with the resignation of these directors,  the Registrant's
Board of Directors  reduced the number of directors  comprising the Registrant's
Board of Directors from ten to eight.

ITEM 8.01    OTHER EVENTS

         On September  17, 2004,  the  Registrant  completed  the  repurchase of
77,134  shares  of its  outstanding  common  stock,  reducing  the  Registrant's
outstanding  common  stock  to  1,588,598  shares.  In  addition,   the  Central
Co-operative  Bank Employee  Stock  Ownership  Trust (the "ESOP")  completed the
purchase of 77,134 share of the  Registrant's  common stock. The Company and the
ESOP purchased the shares pursuant to the terms of the Stock Purchase Agreement,
dated  September  13,  2004,  by and  among the  Registrant  and the ESOP and PL
Capital,  LLC, Financial Edge Fund, L.P.,  Financial  Edge-Strategic Fund, L.P.,
Goodbody/PL Capital,  L.P.,  Goodbody/PL Capital,  LLC, Richard Lashley, John W.
Palmer and Richard J. Fates.
