THE COMMITTEE TO PRESERVE SHAREHOLDER VALUE

Dear Fellow Stockholders:                                         April 9, 2002

The Committee to Preserve  Shareholder Value (the "Committee"),  as a very large
stockholder,  is writing in  response  to the recent  letter you  received  from
Kankakee Bancorp, Inc. ("KNK"or the "Company").

We have already  sent you proxy  material  that  indicates a range of values for
what the  Company  may be worth in a sale,  based on  previous  transactions  in
Illinois over the last 3 years. In addition,  the proxy material  summarizes our
track record.  Yet the incumbents  insinuate that we don't have a plan, or don't
add anything,  or don't know about "local" interests and businesses,  while they
spend OUR money hiring consultants and experts to help them with "local" issues.
Don't you think we are  better  qualified,  and have more  experience,  than the
incumbents to properly analyze,  structure and negotiate a sale or merger of OUR
company?

Messrs.  Huffman and Cheffer  state that "the board does not believe that adding
the committee's nominees to the board will add any value to the organization."

The following is a chart which clearly demonstrates the increase in value for
the twelve companies where Mr. Seidman (Mr. Williamson was also involved with
FFES) had varying degrees of involvement:

(1)  IBSF was acquired by HUBCO for a fixed exchange ratio of 0.534 shares of HUBCO.  Based on HUBCO's March 30, 1998
     closing price of 38.81, each IBSF share was worth $20.73
(2)  WYNE was acquired by Valley National Bancorp.  Valley paid 1.1 shares for each WYNE share equal to a price of $34.38.
(3)  CFSB was not sold but the Company conducted a Dutch Auction at $16.00 per share for 15% of the outstanding shares.
     Seidman was prorated and sold 57.33% of his shares in the Dutch Auction. The percentage increase is from the date
     Mr. Seidman first purchased his shares, not the date of a filing of a Schedule 13D since none was filed, to the date the
     Dutch Auction was announced.
(4)  No Schedule 13D was filed so the date is the date that the Preliminary proxy material was filed with the Securities and
     Exchange Commission. On November 20, 2001, Vista was sold to United National Bancorp. The transaction provided for each Vista
     Shareholder to receive 75% stock and 25% cash from United National Bancorp. The value per share on November 20, 2001
     of the deal was $28.36.


The only way for Messrs. Seidman and Williamson to help the KNK shareholders is
for you to vote for them on the WHITE PROXY card.

KNK's Board and management have highlighted  last year's financial  performance,
but neglected to explain the Company's  financial  performance for the past five
(5)  years,  which is set  forth on page 3 of the  Company's  Annual  Report.  A
comparison  of the  earnings  performance  for 1997 and  2001  explains  why the
Company does not discuss the issue:




                                                                           
                                                                                        %Average
                                      2001               1997          Difference       Yearly Gain

Net Income                          $3,261,000       $3,012,000        $245,000         1.62%
Tangible Book Value                 $30.22           $26.00            $4.22            3.24%
Net Interest Margin                 3.16%            3.22%              (-.06%)         N/A

Return on Average Assets             .69%            .87%              (-.18)%          N/A

In summary,  the Company  spent more per average  asset for a lower net interest
margin to increase the 5 year average net income a paltry 1.62%  annually.  This
performance is even more  disturbing,  because the 2001 net income was augmented
by approximately $730,217 (after tax $485,887) of net gain on sale of securities
and loans  held for sale.  Without  these  gains,  net  income  would  have been
approximately $2,775,095, significantly lower than the net income for 1997. (See
pages 3 and 30 of the Company's Annual Report).

It is the Committee's  position that the stock repurchases of 46,300 in 2000 and
64,200 in 2001  were  inadequate  and a missed  opportunity  given  the  average
trading prices for our stock at that time.

The Committee is also  mystified  that the Company did not repurchase the shares
sold by the the  James G.  Schneider  Trust  and  Thomas  Schneider.  (James  G.
Schneider  was the father of Thomas  Schneider  and both  served on the Board of
Directors  until  James G.  Schneider's  death on  February  15, 2000 and Thomas
Schneider's  resignation  from the Board on October 31, 2001.) Mr. Seidman asked
for an explanation and still has not received a definitive answer.

The  Committee  also  cannot  understand  why the  Board has not  increased  the
dividend in the past three years.

Finally,  we agree that Sandler O'Neill is one of the leading investment banking
firms,  but we also know that  Sandler  O'Neill is only an advisor and the Board
does not have to follow the advise. We disagree with Sandler O'Neill's presently
disclosed  assignment.  Mr. Seidman has worked  closely with Sandler  O'Neill to
maximize  the value  for the  shareholders  of  several  of the  above-mentioned
companies.  The Committee thinks that in order to maximize the value for all the
shareholders,  Sandler  O'Neill  must be  retained  to  prepare a present  value
analysis of the Company's  business plan and compare the value against a sale of
the Company.

It is the  Committee's  position  that you  should  elect  Messrs.  Seidman  and
Williamson,  your fellow  stockholders,  to the Board, by voting the WHITE PROXY
today, and know that we are committed to maximizing our shareholder value.
