Item 4.    Changes to Registrant's Certifying Accountant

On April 9, 2002, the Board of Directors of Trustmark  Corporation  (Trustmark),
based on the  recommendation  of its Audit  Committee,  decided not to renew the
engagement  of  its  independent   public   accountants,   Arthur  Andersen  LLP
(Andersen).  This determination  followed Trustmark's decision to seek proposals
from other independent  accountants to audit Trustmark's  consolidated financial
statements for the year ending  December 31, 2002.  Written  proposals have been
received and the selection of a new independent  public  accountant will be made
in the near future.

During  Trustmark's two most recent fiscal years ended December 31, 2001, and in
the interim  period between  December 31, 2001 and April 9, 2002,  there were no
disagreements  between  Trustmark  and  Andersen  on any  matter  of  accounting
principles, financial statement disclosure or auditing scope or procedure which,
if not resolved to Andersen's  satisfaction,  would have caused Andersen to make
reference to the matter of the  disagreement  in connection  with their reports.
Andersen's reports on Trustmark's  consolidated financial statements for each of
the years ended 2001 and 2000, did not contain an adverse  opinion or disclaimer
of opinion,  nor were they qualified or modified as to uncertainty,  audit scope
or accounting principles.  Trustmark has requested that Andersen furnish it with
a letter, addressed to the Commission, stating whether or not it agrees with the
above statements. A letter from Andersen is attached as Exhibit 16.

Andersen's report on Trustmark's  consolidated financial statements for the year
ended  2001,  dated  January 8,  2002,  was  issued on an  unqualified  basis in
conjunction  with the filing of  Trustmark's  Annual Report on Form 10-K for the
year ended December 31, 2001, filed on March 25, 2002.

None of the reportable  events  described under Item  304(a)(1)(v) of Regulation
S-K occurred within  Trustmark's two most recent fiscal years and in the interim
period between December 31, 2001 and April 9, 2002.
