Forward –Looking Statements

This Current Report on Form 8-K includes forward-looking statements. These forward-looking statements can be identified as such because the statements include expected recoveries and rate of returns in the rate order approved by the IUB which are forward-looking. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those currently anticipated. Actual results could be affected by the following factors, among others:

— state regulatory or governmental actions, and future regulatory proceedings;

— IPL’s ability to obtain adequate and timely rate relief to allow for, among other things, the recovery of operating costs, capital expenditures and deferred expenditures, the earning of reasonable rates of return and the payment of expected levels of dividends;

— economic and political conditions in IPL’s service territory; and

— the effectiveness of continued cost control efforts and operating efficiencies.

These factors should be considered when evaluating the forward-looking statements and undue reliance should not be placed on such statements. The forward-looking statements included herein are made as of the date hereof and Alliant Energy and IPL undertake no obligation to update publicly such statements to reflect subsequent events or circumstances.
