To:  Participants in the Employee Stock Ownership Plan of Workingmens Bank

     As described in the enclosed materials, your proxy as a shareholder of WSB
Holding Company ("WSB") is being solicited in connection with an upcoming
Special Meeting of Stockholders of WSB, at which stockholders of WSB will
consider and vote upon a proposal to adopt an Agreement and Plan of
Reorganization, dated as of May 16, 2001 (the "Reorganization Agreement"), by
and between ESB Financial Corporation ("ESB") and WSB, pursuant to which, among
other things, WSB will be merged with and into ESB.  If the merger is approved
and consummated each outstanding share of WSB common stock will be converted
into the right to receive $17.10 in cash or common stock of ESB at the election
of the holder.  I hope you will take advantage of the opportunity to direct, on
a confidential basis, the manner in which shares of WSB common stock allocated
to your account under Wokingmens Bank's Employee Stock Ownership Plan (the
"ESOP") will be voted.

     Enclosed with this letter is a proxy statement/prospectus, which describes
the matter to be voted upon, a voting instruction ballot for the ESOP, which
will permit you to vote the shares allocated to your account under the ESOP, and
a stamped, pre-addressed return envelope.  After you have reviewed the proxy
statement/prospectus, I urge you to vote your shares in the ESOP by marking,
dating, signing and returning the enclosed voting instruction ballot to
_____________________________.  The trustees of the ESOP will vote as directed
the shares held in the ESOP.

     If your voting instructions are not received, the shares allocated to your
account will be voted in the same proportion as the shares under the ESOP have
voted.

     Your Board of Directors has determined the merger to be fair to and in the
best interests of WSB and its stockholders and has unanimously approved the
Reorganization Agreement and the transactions contemplated thereby.  The Board
of Directors unanimously recommends that stockholders vote FOR approval of the
Reorganization Agreement.

     On behalf of the Board, I thank you for your attention to this important
matter.

                                         Sincerely,
