Baird & Co.* *Robert W. Baird & Co., Incorporated is one of the oldest and largest regional investment banking firms in the United States. Baird serves the investment community as investment banker, equity research specialist, broker and asset manager. The firm has 59 offices in 10 states, concentrated in the Midwest. As a WPL Holdings shareowner, you have the [Map] opportunity to approve a merger agreement involving WPL Holdings and two Iowa-based utility companies - IES Industries Inc. and Proposed Interstate Interstate Power Co. Energy Corporation service area The Board of Directors of WPL Holdings encourages you to vote for the combination of these three quality utility companies as Interstate Energy Corporation. The Interstate Energy Corporation merger proposal "offers superior long-term returns to shareholders," according to an Aug. 19 analysis issued by Robert W. Baird & Co., a Milwaukee-based regional investment banking firm. Please take the time to send in your WPL Holdings proxy card prior to the WPL Holdings annual meeting on Thursday, Sept. 5. If you have misplaced your proxy materials or have any questions, please feel free to contact WPL Holdings Shareowner Services at 1-800-356-5343. [Logo] WPL Holdings, Inc. [The following letter from Erroll B. Davis, Jr., President and Chief Executive Officer of WPL Holdings, Inc., is being distributed to all shareowners of WPL Holdings, Inc. starting on August 27, 1996.] [LOGO] WPL Holdings, Inc. 222 West The parent of Wisconsin Power and Washington Avenue Light Company PO Box 2568 and Heartland Development Madison, WI 53701-2568 Corporation 608/252-4888 August 27, 1996 Dear WPLH Shareowner: I would appreciate a few moments of your time to share some thoughts about the future of your company. On August 15, your Board of Directors agreed to a new stock exchange ratio for IES Industries. WPL Holdings made the offer to preserve the strategic value of the three-way merger announced last November to create Interstate Energy Corp. (IEC), involving WPL Holdings, Cedar Rapids-based IES Industries and Dubuque-based Interstate Power Co. As part of IES' actions on August 15, its Board of Directors rejected an unsolicited proposal from MidAmerican Energy Co. (MEC). According to Lee Liu, IES' Chairman of the Board, President and CEO, the IES Board felt the MidAmerican offer was incapable of delivering all that it had promised, nor was it focused on a long-term strategic plan for the future. Unfortunately, MidAmerican is attempting to block IES -- and therefore WPLH -- from taking a step toward a stronger future. Before the September 5 Annual Meeting, you may be seeing a great deal of information in the media and elsewhere. I apologize for the tremendous amount of material and paper that these efforts generate. Laws and regulations require that we provide you a significant amount of information as you decide about the future of WPLH. I can, however, sum up in a few words why your Board believes that the merger with IES Industries and Interstate Power Co. is best for WPLH: - The strategic three-way merger positions WPLH for regional growth with access to high-growth markets. - The merger will produce a company that is financially sound, ready to build on our heritage of strong earnings. - The merger is a good balance for shareowners, customers, employees and the communities we serve. And we are not the only ones who see the value of this unprecedented three-way merger. Last week, Robert W. Baird & Co., a regional investment banking firm based in Wisconsin, wrote in a report directed at financial analysts located throughout the Midwest: "We recommend that IES shareholders pass up the potential near-term benefits offered by MEC's team and join IEC, a team we believe offers superior long-term returns to shareholders. ..." Please Vote! If you have already mailed back the proxy card that came with the original proxy materials, and you are satisfied with your vote, you do not need to send in another proxy card. If, on the other hand, you just haven't gotten around to filling out the original (white) proxy card, please return the lavender-colored proxy card you received earlier this week. Please note that the lavender-colored card needs to reach us before the September 5 WPLH Annual Meeting to count. Your vote will help position Interstate Energy Corp. to maintain low energy rates and high- quality customer service for more than 1 million energy customers in a four-state region. We are proud of our past success in enhancing long-term shareowner value. And like our merger partners, we believe that our friendly alliance will further enhance your investment. Should you have any questions, please call our Shareowner Services toll free at 1-800-356-5343. Regards, Erroll B. Davis, Jr. President and CEO [The following is an article appearing in the Interstate Energy Corporation Merger Update dated August 27, 1996, which is distributed to employees of WPL Holdings, Inc., IES Industries Inc. and Interstate Power Company.] IES BOARD OF DIRECTORS REJECTS UNSOLICITED OFFER FROM MIDAMERICAN As IES, IPC and WPLH employees have learned through their individual companies' internal communications, MidAmerican Energy Co. of Des Moines made an unsolicited offer on Aug. 4 to acquire IES. On Aug. 16, IES Chairman, President and CEO Lee Liu, IPC Executive Vice President Mike Chase and WPLH President and CEO Erroll B. Davis Jr. convened in Cedar Rapids for a press conference and a teleconference for financial analysts. The topic, of course, was the merger partners' reaction to the unsolicited MidAmerican offer. Lee Liu announced that, after careful consideration, the IES Board of Directors unanimously voted to reject MidAmerican's unsolicited offer. Further, the three executives announced that IES, IPC and WPLH have agreed on a new stock exchange ratio for IES. This agreement reflects a commitment to the strategic value of the unprecedented three way merger to customers, shareowners and employees. Under terms of the agreement, holders of IES Industries common stock will receive 1.14 shares of Interstate Energy Corp. common stock for each share of IES stock they own. Previously, the agreement provided 1.01 shares of IEC common stock for each share of IES common stock.
