Business Editors

KANSAS CITY, Mo.--(BUSINESS WIRE)--June 5, 2002

The Aquila Merchant Services subsidiary of Aquila, Inc. (NYSE:ILA) announced that it responded today to the Federal Energy Regulatory Commission (FERC) data requests on gas trading in the Western Systems Coordinating Council and Texas, and again confirms it has not conducted round-trip trades.

These transactions are simultaneous sell-buyback trades of the same product with the same party at the same price for the purpose of increasing volume.

"After a thorough review of more than 24,000 gas trades for the years 2000 and 2001, we are confirming that our gas trading practices were proper and in full compliance with the FERC regulations and standards," said Ed Mills, Aquila Merchant's president and chief operating officer. "In all three recent FERC reviews, we've stated that none of our trades were for the purpose of increasing volumes or revenue, impacting market prices, or for any other improper business purpose. Our policy continues to be very clear on this. All trades are conducted for legitimate business purposes."

Aquila and more than 100 other companies received fact-finding letters from the FERC seeking information by today on potential "round-trip" or "wash" transactions during 2000 and 2001 in the Western Systems Coordinating Council (WSCC) and Texas for natural gas.

As previously disclosed, some of the trades reviewed may have some of the characteristics of sell-buyback trades. Those trades that may have some characteristics of sell-buyback trades accounted for less than one-half of one percent of the company's trading and marketing revenues. However, these trades were conducted for legitimate business purposes such as determining market price, depth and direction and to manage the risk of Aquila's portfolio due to changing market information.
