ITEM 5. OTHER MATTERS     
   
  Reference is hereby made to the registrant's Quarterly Report on Form 10-Q
for the quarterly period ended June 30, 1995, as filed by the registrant with
the Securities and Exchange Commission on August 14, 1995 (the "August 14 10-
Q"). The version of the Agreement and Plan of Merger, dated as of August 11,
1995, by and among the registrant, CIPSCO Incorporated, Arch Holding Corp. and
Arch Merger Inc. (the "Merger Agreement") which was filed as Exhibit 2(a) to
the August 14 10-Q (the "August 14 Exhibit 2(a)") and incorporated by reference
into Item 5 of the August 14 10-Q inadvertently contained a proviso in Section
9.3 thereof which was not a part of the Merger Agreement and was not agreed to
by the parties thereto. The full text of the correct version of the Merger
Agreement is attached hereto as Exhibit 2(a), and incorporated herein by
reference. All references to the Merger Agreement in Item 5 of the August 14
10-Q, including the incorporation by reference into such Item of the Merger
Agreement, are hereby deemed to refer to the version of the Merger Agreement
filed herewith.     
 
ITEM 6. EXHIBITS AND REPORTS ON FORM 8-K
   
  Reference is hereby made to the Merger Agreement which was filed as the
August 14 Exhibit 2(a) to the August 14 10-Q. The last three lines of Section
9.3(a) of the August 14 Exhibit 2(a) inadvertently contained a proviso which is
not a part of the Merger Agreement executed and agreed to by the parties
thereto. The full text of the correct Merger Agreement is attached as Exhibit
2(a) hereto and supercedes the August 14 Exhibit 2(a) in its entirety.
