 FOR IMMEDIATE RELEASE

          WESLEY A. BROWN APPOINTED TO JACK HENRY BOARD OF DIRECTORS

 Monett, MO - August 31, 2005 - Jack Henry & Associates, Inc. (Nasdaq: JKHY),
 a leading provider  of integrated  computer systems  and ATM/debit  card/ACH
 transaction processing,  today announced  that it  has appointed  Wesley  A.
 Brown, 51, to its Board of  Directors.  Mr. Brown  will fill the open  board
 seat that resulted from  the death  of Burton O. George  in  July 2005.  Mr.
 George had been a dedicated director since 1987.

 This appointment will maintain Jack Henry's seven-member board that includes
 four independent outside directors and three corporate officers.

 According to Jack Prim, CEO of Jack Henry & Associates, "We again extend our
 condolences to  the George  family, and  want  to formally  acknowledge  our
 gratitude for Burton's  dedicated service and  the guidance he  consistently
 provided.  While we will miss his ongoing contributions, we believe we  have
 filled his seat with a highly qualified and enthusiastic board member."

 Mr. Brown is currently the managing  director and president of  Denver-based
 St. Charles Capital, LLC.  Prior to founding St. Charles Capital, he  served
 as managing  director  of McDonald  Investments,  Inc. (2001  to  2004),  as
 executive vice president of the Wallach Company, Inc. (1991 to 2000), and as
 senior vice president  in the Corporate  Finance Department  of Boettcher  &
 Company (1981 to 1990).  He was awarded a Masters in Business Administration
 from the  Graduate School  of Business  at the  University of  Chicago,  and
 obtained his undergraduate degree from the University of Colorado.

 Kevin Williams, CFO  of Jack Henry  & Associates, said,  "Wes has  extensive
 knowledge of  financial institutions  and the  financial services  industry,
 which is largely  based on  years as  an investment  banker  specializing in
 financings and strategic  transactions for commercial banks and thrifts.  In
 fact, since January 1, 1993, he has personally negotiated approximately half
 of all  the  bank and  thrift  merger  transactions that  have  occurred  in
 Colorado.  He also has wide experience  serving on  and  leading a number of
 local and national Boards of various civic organizations."

 "We are  excited to  add Wes  to  our Board  of  Directors and  believe  his
 knowledge and experience will  complement his fellow  Board members and  add
 strategic value to Jack Henry," concluded Mr. Prim.
