               YOUR VOTE IS IMPORTANT! VOTE THE WHITE PROXY CARD!
                                                -----

Dear Fellow Stockholder:

     PL Capital asks why we are opposing their  nominees.  The answer is simple!
Your Board believes that they are wrong for your Company.

     The PL Capital  Group is a short-term  speculator  with only one  strategy:
Sell the Company as quickly as  possible.  That has been their agenda with every
other bank they have made a large investment in and it is the only strategy they
have articulated for Central.  Your Board has considered their strategy with its
financial  advisor and unanimously  concluded that this is not the time to sell.
SINCE PL  CAPITAL  HAS NO OTHER  IDEAS,  THERE IS NO REASON TO HAVE THEM ON YOUR
BOARD.

              YOUR BOARD'S NOMINEES HAVE THE RIGHT QUALIFICATIONS!
                                             -----

     Our nominees are highly regarded local businessmen who understand the needs
of our customers and community.  Directors  Gilgun and Santini each have decades
of  experience  in local  real  estate,  which is the  backbone  of our  lending
business.  It would  be  difficult  to find  someone  with a more  distinguished
community  banking  career  than Paul Bulman who has been the  President  of two
local community banks and is a former Massachusetts Commissioner of Banks.

     The big bank backgrounds of PL Capital's  nominees are far removed from our
community banking  business.  Our nominees may not have graduated from Yale, but
they are the kind of  hard-working  individuals  who built this Company and they
deserve your support.

     AS  SUBSTANTIAL  STOCKHOLDERS,  YOUR BOARD AND MANAGEMENT  ALSO  UNDERSTAND
STOCKHOLDER  VALUE.  Chairman  Joe Doherty and  President  John  Doherty are the
Company's largest individual owners with over 12% of outstanding shares. Through
the ESOP,  which  holds an  additional  12% of the stock,  and their  individual
holdings,   the  rest  of  management   and   employees  are  also   substantial
stockholders.

   IF PL CAPITAL IS SO CONCERNED ABOUT SPENDING STOCKHOLDERS' MONEY, WHY DON'T
             THEY AGREE TO FOREGO REIMBURSEMENT OF THEIR EXPENSES?

     In their most  recent  letter,  PL Capital  complains  about the money that
management is spending to oppose their proxy  solicitation.  Your Board does not
want to spend  this money but we  believe  we have an  obligation  to oppose the
election of nominees whose agenda is contrary to  stockholders'  best interests.
Moreover,  PL Capital  states  they intend to seek  reimbursement  of their many
thousands  of dollars in  expenses  in  soliciting  proxies.  IF THEY ARE REALLY
CONCERNED ABOUT YOUR COMPANY'S EXPENSES, THEY SHOULD STOP PILING THEM ON!

           IF PL CAPITAL IS LOOKING FOR PERFORMANCE, IT'S RIGHT HERE!

     As much as PL Capital may try,  they cannot  deny that  Central's  earnings
performance trend is upward. EARNINGS WERE UP 94% IN THE FIRST QUARTER. EARNINGS
PER SHARE NEARLY DOUBLED BETWEEN THESE PERIODS.  Annualized return on equity for
the first  quarter  was over 10%.  Assets  and loans have grown at an 8% and 10%
compound annual growth rate,  respectively,  since fiscal 1997.



           CENTRAL'S STOCK HAS OUTPERFORMED PL CAPITAL'S HEDGE FUNDS!

     According  to the  August  issue of SNL  Financial's  Thrift  Investor,  PL
Capital's hedge fund,  Financial Edge Fund,  returned 11% to its investors after
fees and expenses during the first half of 2002 and its Financial Edge-Strategic
Fund returned  8.5%.  Investors in Central  Bancorp,  however,  saw the value of
their  shares  increase  during this period by 13.9%  assuming  reinvestment  of
dividends. The price of your stock has risen from $25.60 at the beginning of the
year to $30.40 at June 30 to $31.75 at September 13, 2002.

                    INDEPENDENCE HAS PROVEN THE RIGHT COURSE!

     PL  Capital  complains  that the  Board  should  have sold the  Company  in
response to a 1996 stockholder proposal made by another hedge fund operator.  PL
Capital  fails to note  that  the  proponent  of that  proposal  predicted  that
Central's  stockholders would receive $22 per share in a buyout.  SINCE THE 1996
ANNUAL MEETING, THE DIVIDEND-ADJUSTED  TRADING PRICE OF CENTRAL'S STOCK HAS MORE
                                                                            ----
THAN  DOUBLED AND STANDS  NEARLY 50% ABOVE THE  DISSIDENT'S  PROJECTED  TAKE-OUT
- -------------
VALUE!

     Your Board  unanimously  recommends that you vote for its three nominees on
the WHITE proxy card. DO NOT RETURN PL CAPITAL'S  GREEN PROXY CARD. USE ONLY THE
                         ---
BOARD'S WHITE PROXY CARD!

                                         Sincerely,

                                         /s/ John D. Doherty

                                         John D. Doherty

                             YOUR VOTE IS IMPORTANT

1.   The Board of Directors  urges you to DISCARD the GREEN proxy card  recently
     sent to you by the PL Capital Group. A "WITHHOLD  AUTHORITY" vote on the PL
     Capital Group's Green proxy card is NOT a vote for the Board's nominees. To
     vote FOR your Company's nominees you MUST execute a WHITE proxy card.
2.   If you  voted on a Green  proxy  card BUT WISH TO  SUPPORT  YOUR  COMPANY'S
     NOMINEES,  please sign,  date and mail the enclosed WHITE proxy card in the
     postage-paid envelope provided as soon as possible.
3.   Remember - ONLY YOUR LATEST DATED PROXY WILL  DETERMINE HOW YOUR SHARES ARE
     TO BE VOTED AT THE MEETING.
4.   If any of your  shares  are  held in the  name of a bank,  broker  or other
     nominee,  please contact the party  responsible for your account and direct
     them to vote your  shares for your  Company's  nominees  on the WHITE proxy
     card.
5.   For assistance in voting your shares,  or for further  information,  please
     contact our proxy solicitor:
