ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

(a)  At its regular  board  meeting on April 29, 1999, the Board of Directors of
Wintrust  Financial  Corporation  (the  "Company")  voted to  approve  the Audit
Committee's recommendation to engage the accounting firm of Ernst & Young LLP as
independent  accountants  for the Company for the year ending December 31, 1999.
The work of KPMG LLP was  terminated  on April 29, 1999,  subsequent to the Form
10-K report for  December  31,  1998,  which was filed with the  Securities  and
Exchange Commission on March 30, 1999.

(b)  During the audits of the two fiscal  years ended December  31, 1998 and the
subsequent   interim  period  through  April  29,  1999,   there  have  been  no
disagreements with KPMG LLP on any matter of accounting principles or practices,
financial  statement  disclosure,   or  auditing  scope  or  procedures,   which
disagreements  if not resolved to their  satisfaction  would have caused them to
make  reference in connection  with their  opinion to the subject  matter of the
disagreement, nor have there been any reportable events.

(c)  KPMG LLP's audit reports on the Company's consolidated financial statements
as of and for the years ended  December 31, 1998 and 1997,  contained no adverse
opinion or  disclaimer  of opinion  and were not  qualified  or  modified  as to
uncertainty, audit scope or accounting principles.

(d)  The Company has requested that KPMG LLP furnish it with a letter  addressed
to the Securities  and Exchange  Commission  stating  whether it agrees with the
above  statements.  A copy of KPMG LLP's letter to the  Securities  and Exchange
Commission, dated May 6, 1999, is filed as Exhibit 16 to this Form 8-K.
