                                September 6, 2002


                             YOUR VOTE IS IMPORTANT!

Dear Fellow Stockholder:

     A dissident  stockholder group calling itself the PL Capital Group has sent
you a proxy  statement and a green proxy card.  The principals of PL Capital are
hedge fund operators from  Naperville,  Illinois who want to replace two of your
Board's  nominees  for  directors  at the 2002  Annual  Meeting  with  their own
handpicked nominees.

          WE URGE YOU NOT TO RETURN PL  CAPITAL'S  GREEN CARD.  DO NOT VOTE
                      ---                                       -- ---
          FOR PL CAPITAL'S NOMINEES. HERE'S WHY.

     O    YOUR BOARD HAS PRODUCED A 94% FIRST QUARTER EARNINGS  INCREASE AND HAS
                                    --- ----- --------------------------
          GROWN "CORE  INCOME"(1) PER SHARE AT BETTER THAN A 15% COMPOUND ANNUAL
                                                             -------------------
          GROWTH RATE SINCE FISCAL 1999.
          -----------

     O    YOUR  BOARD HAS  PRODUCED A NEARLY  90% TOTAL  RETURN TO  STOCKHOLDERS
                                              -----------------
          (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.

     O    YOUR BOARD'S  NOMINEES FOR DIRECTORS HAVE THE LOCAL COMMUNITY  BANKING
          AND  REAL  ESTATE  EXPERIENCE  THAT  HAS BEEN  CRITICAL  TO  CENTRAL'S
          SUCCESS.

     O    YOUR  BOARD IS  COMMITTED  TO  BUILDING  STOCKHOLDER  VALUE BY GROWING
          EARNINGS. NOW IS NOT THE TIME TO SELL YOUR COMPANY.
                           ---

                DON'T GIVE BOARD SEATS TO SHORT-TERM SPECULATORS
                           WITH A SINGLE-ISSUE AGENDA

     The members of the PL Capital Group appear to have been  stockholders  only
beginning in 2001 when they began accumulating shares through an offshore entity
and their  other  investment  vehicles.  Although  PL Capital  claims that their
nominees will be open to all methods of maximizing  stockholder value, they have
been calling for a sale of your Company since they filed their initial  Schedule
13D in July 2001.

     In the Board's opinion, a sale at this time would not maximize  stockholder
value since it would not reflect the possible future benefits from the strategic
initiatives the Board has put in place and that, as

- --------
(1)   Core income per share was as follows: FY99-$1.15;  FY00-$1.54; FY01-$1.55;
FY02-$1.78.  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%.


described in this letter, are producing results.  Moreover,  we believe that the
presence of a single-issue  faction on your Board would be highly disruptive and
could   jeopardize  our  ability  to  continue  to  build  long-term  value  for
stockholders.

     DON'T  BE  MISLED  BY PL  CAPITAL'S  SELECTIVE  ANALYSIS  OF OUR  FINANCIAL
RESULTS.  PL Capital tries to make an issue of the Bank's deposit growth even as
our loans have grown 59% and our assets have grown 46% over the past five fiscal
years. In their proxy materials,  PL Capital claims that earnings per share have
grown very slowly from 1998 to 2002. PL Capital,  however, ignores the fact that
Central's results of operations for fiscal 1998 included a $1.1 million net gain
on  securities  sales while  earnings for the most recent  fiscal year  included
$150,000 in net securities losses. If they looked at Central's "core income," as
financial  publications  such as SNL Financial's  Thrift Investor do, they would
see that Central's core income per share has grown 47% since fiscal 1998 and has
grown at better than a 15% compound annual growth rate since fiscal 1999.

     STOCKHOLDERS  SHOULD  CONSIDER PL CAPITAL'S TRACK RECORD.  For example,  PL
Capital  previously  nominated  its own slate for election to the board of Haven
Bancorp. In preliminary proxy materials filed with the SEC on March 30, 2000, PL
Capital predicted that Haven would be worth $22 to $27 per share in a merger. On
June 27,  2000,  after PL Capital's  nominees  (including  one of their  current
nominees for your Board) had been given board seats, Haven agreed to a merger in
which its shares were  valued at only $18.85 per share,  over $3.00 a share less
than the low end of PL Capital's range!

         YOUR BOARD HAS EARNED YOUR SUPPORT THROUGH PERFORMANCE

     YOUR  BOARD'S  STRATEGY  TO ENHANCE  CORE  PROFITABILITY  IS SHOWING  SOLID
RESULTS.

     o    As shown in the Stock  Performance  Graph in our proxy statement,  the
          total return on Central's common stock has outstripped the S&P 500 and
          the Nasdaq Bank Index over the past five years!  For the twelve months
          ended August 31, 2002,  our stock was up 29% from $24.80 to $32.01 per
          share while the S&P 500 was in negative territory.

     o    First  quarter  earnings  increased  by 94% over the first  quarter of
          fiscal 2002.

     o    Core deposits  (deposits  other than time  deposits) have increased by
          nearly 25% since March 31, 2000.

     o    Higher-yielding   commercial  loans  and  commercial   mortgages  have
          increased  to 31% of the loan  portfolio  at June 30, 2002 from 21% at
          March 31, 2000.

     o    Non-performing   loans  and  net  loan   charge-offs   are   virtually
          non-existent.

     YOUR BOARD HAS DEMONSTRATED ITS COMMITMENT TO BUILDING STOCKHOLDER VALUE.

     o    Since 1999, we have repurchased over 18% of our common stock.

     o    We have  continued  to invest in our common  stock  through  the ESOP,
          which now owns over 12% of the Company's outstanding stock.

     o    We have paid continual quarterly cash dividends since 1996.


                                       2

                         "NOW IS NOT THE TIME TO SELL!"
                                 ---

     Contrary  to PL  Capital's  assertions,  the Board of  Directors  carefully
considered  PL Capital's  views before  taking a position on whether to sell the
Company. The Board met with its independent financial advisor, Feldman Financial
Advisors,  Inc., Washington,  D.C., both in July 2001 after PL Capital filed its
first 13D and in August 2002 prior to filing preliminary proxy materials.

     At both meetings, Feldman Financial told the Board: "Now is not the time to
sell. To sell the Company now would not allow the  stockholders  to  potentially
reap the  benefits  of the  hard  work of  recent  years  to  improve  operating
results."

     Your Board believes that in an era of more and more big,  impersonal  banks
resulting  from the recent  merger  activity  in our  market,  there is a golden
opportunity  for a responsive,  customer-focused  community bank like Central to
build  market  share  and  increase   franchise  value.  THE  COMPANY'S  LARGEST
STOCKHOLDERS,  JOSEPH DOHERTY AND JOHN DOHERTY WHO TOGETHER OWN 202,205  SHARES,
OR OVER 12% OF YOUR COMPANY'S  OUTSTANDING STOCK, AGREE THAT INDEPENDENCE IS THE
BEST STRATEGY.  THE DOHERTYS HAVE DEMONSTRATED THEIR CONFIDENCE IN THE COMPANY'S
FUTURE BY ACQUIRING OVER 60,000 SHARES IN THE PAST 2 YEARS.

               YOUR BOARD'S NOMINEES UNDERSTAND COMMUNITY BANKING

      Your Board's nominees have substantial experience in local community
banking.

PAUL E. BULMAN

     o    Former President of two Massachusetts community banks
     o    Former Massachusetts Commissioner of Banks, 1983 to 1987
     o    Chairman,  Policy  Holders  Protective  Committee,  Savings  Bank Life
          Insurance Company

JOHN F. GILGUN, JR.

     o    Former Mayor, Woburn, Massachusetts
     o    Over 40 years  experience in local  commercial  and  residential  real
          estate
     o    Director since 1987

MARAT E. SANTINI

     o    Over  50  years  experience  in  local   commercial,   industrial  and
          residential real estate construction
     o    Director since 1972

     Messrs.   Gilgun's  and  Santini's  expertise  in  local  real  estate  and
construction  has made  them  invaluable  members  of  Central  Bank's  Security
Committee,  which  functions  as the Bank's loan  approval  committee  and whose
members are  required by law to inspect real estate  securing  loans made by the
Bank.  Since  nearly 80% of Central  Bank's  assets are  invested in real estate
related  loans and  securities,  their  real  estate  and  construction  related
experience  is truly vital to the success of your Company.  Your Board  believes
that it is due to the efforts of this Committee  including  Messrs.  Santini and
Gilgun that the Bank has been able to maintain  its  extraordinary  loan quality
with no nonperforming loans as of June 30, 2002.
