ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     On March 14,  2003,  the  Auditing  Committees  of CILCORP Inc. and Central
Illinois  Light  Company  (the  "Registrants")  dismissed  Deloitte & Touche LLP
("Deloitte & Touche") as the Registrants' independent public accountants subject
to completion of its services  related to the audits of the fiscal year 2002 and
engaged  PricewaterhouseCoopers LLP  ("PricewaterhouseCoopers")  to serve as the
Registrants'  independent  public  accountants  for the fiscal  year  2003.  The
Registrants'    Auditing    Committees    made    this    replacement    because
PricewaterhouseCoopers  is serving as the independent public accountants for the
Registrants' parent company, Ameren Corporation, for the fiscal year 2003.

     Deloitte &  Touche's  reports on the  Registrants'  consolidated  financial
statements for the fiscal years ended December 31, 2001 and 2000 did not contain
an adverse  opinion or a  disclaimer  of  opinion,  nor were they  qualified  or
modified as to uncertainty, audit scope or accounting principles.

     During the  Registrants'  two fiscal years ended December 31, 2001 and 2000
and the  subsequent  interim  period  through  March  14,  2003,  there  were no
disagreements  with Deloitte & Touche on any matter of accounting  principles or
practices,  financial statement disclosure or auditing scope or procedure which,
if not  resolved  to Deloitte & Touche's  satisfaction,  would have caused it to
make  reference  to the  subject  matter in  connection  with its reports on the
Registrants' consolidated financial statements for such years, and there were no
reportable events, as listed in Item 304(a) (1) (v) of Regulation S-K.

     The  Registrants  have  provided  Deloitte  &  Touche  with a  copy  of the
foregoing disclosures. Attached as Exhibit 16.1 is a copy of Deloitte & Touche's
letter, dated March 20, 2003, stating its agreement with such statements.

     During the  Registrants'  two fiscal years ended December 31, 2002 and 2001
and the subsequent  interim period through March 14, 2003, the  Registrants  did
not consult  PricewaterhouseCoopers  regarding  the  application  of  accounting
principles to a specified  transaction,  either contemplated or proposed, or the
type of audit  opinion that might be rendered on the  Registrants'  consolidated
financial  statements,  or any other  matter or  reportable  event that would be
required to be reported in this Current Report on Form 8-K.

ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     On March 14,  2003,  the  Auditing  Committees  of CILCORP Inc. and Central
Illinois  Light  Company  (the  "Registrants")  dismissed  Deloitte & Touche LLP
("Deloitte & Touche") as the Registrants' independent public accountants subject
to completion of its services  related to the audits of the fiscal year 2002 and
engaged  PricewaterhouseCoopers LLP  ("PricewaterhouseCoopers")  to serve as the
Registrants'  independent  public  accountants  for the fiscal  year  2003.  The
Registrants'    Auditing    Committees    made    this    replacement    because
PricewaterhouseCoopers  is serving as the independent public accountants for the
Registrants' parent company, Ameren Corporation, for the fiscal year 2003.

     Deloitte &  Touche's  reports on the  Registrants'  consolidated  financial
statements for the fiscal years ended December 31, 2001 and 2000 did not contain
an adverse  opinion or a  disclaimer  of  opinion,  nor were they  qualified  or
modified as to uncertainty, audit scope or accounting principles.

     During the  Registrants'  two fiscal years ended December 31, 2001 and 2000
