[The following is the News Bulletin sent to all WPL Holdings, Inc. employees and retirees on August 19, 1996 regarding the voice-mail message Erroll B. Davis, Jr., President and Chief Executive Officer of WPL Holdings, Inc., broadcast to all WPL Holdings, Inc. employees] [Logo] WPL Holdings, Inc. News Bulletin From WP&L's Corporate Communications Dept. - 608/252-3187 For employees and retirees of WPL Holdings, Inc., Heartland Development Corp. and Wisconsin Power and Light Co. NR14-96 August 19, 1996 DAVIS UPDATES EMPLOYEES ON EVENTS RELATING TO NEW STOCK- EXCHANGE RATIO ANNOUNCEMENT The following is a voice-mail message that was sent Friday evening, August 16, from Erroll Davis to all employees. This is Erroll Davis with a voice mail message to all WPL Holdings employees. I thought this might be a good opportunity for a short update in follow-up to the message I left you Friday morning announcing the new stock-exchange ratio agreed to by WPL Holdings, IES Industries and Interstate Power Company. After the announcement was issued early Friday, I left Madison for Cedar Rapids, and joined IES Chairman Lee Liu and Interstate Power Executive Vice President Mike Chase in a teleconference discussion with financial analysts and a joint press conference attended by several media representatives. Market reaction to our announcement on Friday was generally favorable, as the valuation of WPL Holdings stock experienced only a slight down-tick, while both IES and Interstate Power closed higher for the day. We realize however, that a proxy contest involving our merger agreement has been promised by MidAmerican Energy Company, the Des Moines-based utility that announced an unsolicited offer to acquire IES Industries - one of our two Iowa-based merger partners. This afternoon, MidAmerican announced that it would launch its proxy fight. Accordingly, IES shareowners will soon choose between the unsolicited offer from MidAmerican and the three-way Interstate Energy Corporation proposal that we believe is in the best interests of our customers, shareowners and employees. If an ongoing proxy contest involving three electric utility companies in the Kansas City Area is any indication, it is conceivable that this proxy fight could make things a little more turbulent before Interstate Energy Corporation becomes a reality. We will, nevertheless, move and move quickly to capture the strategic value that would accrue from our unique three-way strategic alliance. One final thought before closing. Several employees have expressed concerns regarding an item that surfaced in the IES Industries news release that accompanied the August 16 News Bulletin regarding the new exchange ratio. The IES news release discussed headquarters locations for the four proposed business units of Interstate Energy Corporation. Specifically, the release noted that the Administration business unit would be headquartered in Dubuque; the Generation business unit would be headquartered in Madison; while the Energy Marketing and Delivery and non- regulated business units would be headquartered in Cedar Rapids. Let me urge employees not to be unnecessarily concerned about the location of the four business-unit headquarters. Frankly, I would expect there to be little if any correlation between the site of a given business-unit's headquarters and the physical location of employees who report up through that particular business unit. While some individual employees may, in fact, be asked to relocate, it is highly unlikely that existing departments would be moved en masse from one location to another. Instead, employees who report up through all four business units will be spread across the entire Interstate Energy Corporation organization. This is the essence of the matrix management system that has been agreed upon by all three companies. In the meantime, let me thank you once again for your continuing support. I hope you had a good week; I hope you have a good weekend and, as always, please continue to work safely and play safely as well. Thank you.
