Aquila Announces Additional Increase in Aggregate Principal Amount of Tender Offer and Extends Expiration Date of Tender Offer


KANSAS CITY, Mo., June 9, 2006 (PRIMEZONE) -- Aquila, Inc. (NYSE:ILA) today announced that it has further increased to $350 million the aggregate principal amount (the "Maximum Tender Amount") that it could be obligated to accept for payment in its pending cash tender offer for certain of its outstanding senior notes (the "Notes"). In addition, the company has extended the tender offer for the Notes until 12:00 Midnight, New York City Time, on June 23, 2006, unless extended or earlier terminated by the company (the "Expiration Time"). The Expiration Time may be further extended at the discretion of the company. No other terms of the tender offer are being modified at this time.

The tender offer is conditioned on the satisfaction of certain conditions described in the Offer to Purchase dated May 12, 2006. If any of the conditions are not satisfied, Aquila is not obligated to accept for payment, purchase, or pay for, and may delay the acceptance for payment of, any tendered Notes, in each event, subject to applicable laws, and may even terminate the tender offer. The company expects to accept certain of the Notes for purchase promptly after the Expiration Time and expects that it will pay the purchase price for the Notes on the business day following the date the Notes are accepted. Holders whose Notes are accepted will receive accrued interest from the last interest payment date for such series of Notes, to, but not including, the date the Notes are purchased. Notes tendered may not be withdrawn, except as required by law.
