Item 4. Changes in Registrant's Certifying Accountant.
------------------------------------------------------

         On December 1, 2000,  Keller Bruner & Company,  LLP ("Keller  Bruner"),
the independent certified public accountants which audited FCNB Corp's financial
statements for the year ended  December 31, 1999,  advised FCNB Corp that it had
merged into  McGladrey & Pullen,  LLP and that Keller  Bruner would no longer be
the auditor for FCNB Corp.

         Keller Bruner's report on FCNB Corp's financial statements for the year
ended  December  31, 1999 did not contain an adverse  opinion or  disclaimer  of
opinion,  and were not  modified as to  uncertainty,  audit scope or  accounting
principles.

         During the period  January 1, 1998 to December 31, 1999 and through the
date on which they were merged,  there were no disagreements  with Keller Bruner
on any  matter  of  accounting  principles  or  practices,  financial  statement
disclosure, audit scope or procedure which, if not resolved to its satisfaction,
would have caused it to make reference to such  disagreement  in connection with
its report.
