Item 5.  Other Events
- ---------------------

         On  May  16,  2001,  WSB  Holding  Company   ("WSB"),   a  Pennsylvania
corporation  headquartered  in  Pittsburgh,   Pennsylvania,  and  ESB  Financial
Corporation ("ESB"), a Pennsylvania  corporation  headquartered in Ellwood City,
Pennsylvania,  entered  into  an  Agreement  and  Plan  of  Reorganization  (the
"Agreement")  (including  an Agreement of Merger) which sets forth the terms and
conditions under which WSB will merge with and into ESB (the "Merger").

         The  Agreement  provides  that upon  consummation  of the  Merger,  and
subject to certain  further terms,  conditions,  limitations  and procedures set
forth in the  Agreement,  each  outstanding  share of common  stock of WSB ("WSB
Common Stock") (other than (i) shares as to which  dissenters'  rights have been
asserted and duly  perfected in accordance  with  Pennsylvania  law and (ii) any
shares held by WSB (including treasury shares) or ESB or any of their respective
wholly-  owned  subsidiaries,  in each case other than in a fiduciary  capacity)
shall,  by virtue of the Merger,  and  without any further  action by the holder
thereof,  be converted into and represent the right to receive $17.10 in cash or
common stock of ESB ("ESB Common Stock") at the election of the holder  thereof,
subject to an overall  requirement that 51% of the total  outstanding WSB Common
Stock be exchanged for ESB Common Stock and 49% for cash.

         Concurrently  with the  execution and delivery of the Agreement (i) WSB
entered into a Stock Option  Agreement  with ESB (the "Stock Option  Agreement")
whereby  WSB  granted to ESB an option to  purchase  up to 60,535  shares of WSB
Common Stock at a price of $11.90 per share,  which is exercisable only upon the
occurrence of certain events and subject to an overall profit  limitation to ESB
of  $25,000  (ii) ESB  entered  into a  stockholders  agreement  with  executive
officers  and  directors  of WSB  (the  "Stockholders  Agreement")  whereby  the
executive  officers  and  directors  of WSB agreed to vote  their  shares of WSB
Common  Stock in favor of the Merger at the  meeting of WSB  stockholders  to be
called to approve the Merger.

         Consummation   of  the  Merger  is  subject  to  the  approval  of  the
stockholders  of WSB and the receipt of all required  regulatory  approvals,  as
well as other customary conditions.

         The Agreement,  the Stock Option Agreement,  the Stockholders Agreement
and the press release issued by ESB and WSB on May 16, 2001 regarding the Merger
are incorporated  herein by reference to this report as exhibits.  The foregoing
summaries of the  Agreement,  the Stock Option  Agreement  and the  Stockholders
Agreement do not purport to be complete and are  qualified in their  entirety by
reference to such agreements.
