                       [CENTRAL BANCORP, INC. LETTERHEAD]

                                 OCTOBER 1, 2002

                       THIS IS YOUR FINAL CHANCE TO VOTE!

                           VOTE THE WHITE PROXY CARD!

Dear Fellow Stockholder:

     Central's  annual meeting has been extended to October 11, 2002 in order to
permit the greatest number of stockholders possible to cast their vote!

     For those of you who have voted, we thank you very much. For those who have
not  voted,  YOUR VOTE IS  CRITICAL!  We urge you to vote the WHITE  proxy  card
immediately. This is your last chance to vote!

     o    Institutional  Shareholder  Services (ISS),  widely  recognized as the
          leading  independent  proxy  advisory firm in the United  States,  has
          recommended a vote on the WHITE proxy card for the nominees of Central
          Bancorp--Marat  Santini, John Gilgun and Paul Bulman--in opposition to
          the nominees of PL Capital Group.

     o    Your Board has produced  outstanding  financial  results--a  94% first
          quarter  earnings  increase  and "core  income"1  growth  per share of
          better than 15% compound annual growth rate since fiscal 1999.

     o    Your Board has produced  outstanding  stock price  performance for our
          stockholders--a nearly 90% return (assuming reinvestment of dividends)
          over the past five fiscal  years,  and a 29% stock  price  increase in
          just the past 12 months,  handily  outperforming the S & P 500 and the
          NASDAQ Bank Index over these periods.

YOUR BOARD OF DIRECTORS UNANIMOUSLY URGES YOU TO COMPLETE, SIGN, DATE AND RETURN
MANAGEMENT'S WHITE PROXY CARD, IN ITS POSTAGE-PAID ENVELOPE, VOTING "FOR" ALL OF
ITS NOMINEES.

       PLEASE DO NOT RETURN THE GREEN PROXY CARD TO THE PL CAPITAL GROUP.

                                      Sincerely,

                                      /s/ John D. Doherty

                                      John D. Doherty
                                      President and Chief Executive Officer


___________
1.   For  purposes of this  calculation,  we have used core income as defined by
     SNL Financial, the same source cited by PL Capital as a leading provider of
     financial  data.  SNL  Financial  defines core income as net income  before
     extraordinary  items less the after-tax portion of non-recurring  items and
     the gain on sale of items except loans at an assumed tax rate of 35%.




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:
