[GRAPHIC] Westar Energy(TM) 5 Forward-looking statements: The matters discussed here and elsewhere in this investor presentation are "forward-looking statements." The Private Securities Litigation Reform Act of 1995 has established that these statements qualify for safe harbors from liability. Forward-looking statements may include words like we "believe," "anticipate," "expect" or words of similar meaning. Forward-looking statements describe our future plans, objectives, expectations or goals. Such statements address future events and conditions concerning capital expenditures, earnings, liquidity and capital resources, litigation, rate and other regulatory matters, possible corporate restructurings, mergers, acquisitions, dispositions, including the proposed separation of Westar Industries, Inc., from our electric utility businesses and the consummation of the acquisition of our electric operations by Public Service Company of New Mexico, compliance with debt covenants, changes in accounting requirements and other accounting matters, interest and dividends, Protection One's financial condition and its impact on our consolidated results, environmental matters, changing weather, nuclear operations, ability to enter new markets successfully and capitalize on growth opportunities in non-regulated businesses, events in foreign markets in which investments have been made, and the overall economy of our service area. What happens in each case could vary materially from what we expect because of such things as electric utility deregulation, ongoing municipal, state and federal activities, such as the Wichita municipalization efforts; future economic conditions; legislative and regulatory developments; competitive markets; and other circumstances affecting anticipated operations, sales and costs. Any forward-looking statement speaks only as of the date such statement was made, and we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement was made.
