Item 8.01  Other Events.

As previously disclosed, Trustmark Corporation's subsidiary,  Trustmark National
Bank,  filed  applications  to  become  a  Fed-member,  state-chartered  banking
institution.  On September 14, 2004, after further consideration by the Board of
Directors,  the bank withdrew its  application  to convert to a  state-chartered
member bank,  and informed the  Mississippi  Department  of Banking and Consumer
Finance  and the  Federal  Reserve  accordingly.  Trustmark  National  Bank will
continue to be a national banking  association,  whose primary  regulator is the
Office of the Comptroller of the Currency.
