Faces 76 Asbestos-Related Claims in Illinois Court
--------------------------------------------------
Published September 13, 2002

Ameren Corp., which distributes electricity to 1.5 million customers and
natural gas to 300,000 in Missouri and Illinois, reports that it has 
been named defendant, along with its main operating units Central 
Illinois Public Service Co. (AmerenCIPS) and Union Electric Co., in 76 
asbestos-related lawsuits, of which 62 remained pending.

Ten of the cases have been settled, and four have been dismissed. The 
lawsuits were mostly filed in the Circuit Court of Madison County, 
Illinois.

The company says it received notice of the first lawsuit in March 2001 
with notice of the others occurring in the fourth quarter of 2001 and 
the first quarter of 2002. The number of total defendants named in each
case is large, with more than 40 parties named in all but four of the 
lawsuits.

The claims allege injury from asbestos exposure during plaintiffs' 
activities at the companies' electric generating plants (in the case of 
AmerenCIPS, its former plants which are now owned by Generating 
Company). 

In each lawsuit, the plaintiff seeks unspecified damages in excess of 
$50,000, which, the company says, typically would be shared among the 
defendants.


The company says it believes that the final disposition of the cases 
will not have material adverse effect on its financial position,
results of operations or liquidity.
