NEWS RELEASE -- November 11, 1995
                                Cedar Rapids, IA, Dubuque, IA and Madison, WI

   The joint combination of IES Industries Inc.,  Interstate Power Company
   and WPL Holdings, Inc., resulting in the holding company to be known as 
   Interstate Energy Corporation, will become the first  three-way
   combination in the utility industry.

   IES Industries Inc., Interstate Power Company and WPL Holdings, Inc. today
   announced the signing of a merger agreement providing for the combination
   of the three companies.  The resulting holding company will be known as
   Interstate Energy Corporation.

   The strategic combination has been approved by the respective companies'
   boards of directors and will result in a corporation with a market
   capitalization of approximately $2 billion and assets of nearly $4
   billion.  Interstate Energy Corporation will rank 34th in the nation among
   utility holding companies, based on 1994 revenues.

   The transaction will be structured as a tax-free, stock-for-stock merger. 
   In the merger, holders of IES Industries Inc. common stock will receive
   .98 shares of WPL Holdings common stock for each share of IES Industries
   Inc. common stock they own on the effective date of the merger.  Holders
   of Interstate Power Company common stock will receive 1.11 shares of WPL
   Holdings common stock for each share of Interstate Power Company stock
   they own, and owners of WPL Holdings common stock will retain the number
   of shares of common stock they own on the effective date.  All shares of
   common stock are listed on the New York Stock Exchange.

   The dividend at the effective date of the merger will be the dividend then
   being paid by WPL Holdings.  Subsequent dividend policy will be developed
   by the board of directors of Interstate Energy Corporation.

   After the combination, Wisconsin Power and Light Company, IES Utilities,
   and Interstate Power Company will continue to operate under those names as
   the principal subsidiaries of Interstate Energy Corporation.  WPL Holdings
   will change its name to Interstate Energy Corporation.  IES Diversified
   and Heartland Development Corporation will be combined under one entity to
   manage the diversified operations at Interstate Energy Corporation. 
   Initially, facility headquarters will be as follows:  IES Utilities in
   Cedar Rapids; Interstate Power Company in Dubuque;  Wisconsin Power and
   Light and Interstate Energy Corporation in Madison.

   The combination of these three quality utilities with similar service
   territory characteristics will provide substantial competitive and
   operational advantages within the region in the face of utility
   deregulation.  The combination will enable the operating companies to
   maintain low rates and a high level of customer service, and enhance
   future shareowner value as well.  Estimated savings from the combination
   are projected to be  approximately $700 million over the next 10 years. 
   The majority of these savings will come through economies of scale and
   elimination of redundancies among the three companies.

   The strategic and financial benefits produced by this merger are
   compelling.  This transaction provides shareowners ownership in a company
   with earnings and dividend growth superior to that which each can achieve
   on a stand-alone basis.  Shareowners will participate in a balanced,
   larger company that is better prepared to face competitive pressures.  

   After the combination, Lee Liu, presently chairman, president and chief
   executive officer of IES Industries, will serve as chairman of the board
   of Interstate Energy Corporation.  Wayne H. Stoppelmoor, chairman, 
   president and chief executive officer of Interstate Power Company, will be
   the vice chairman.  Erroll B. Davis Jr., chairman, president and chief
   executive officer of WPL Holdings will become president and chief
   executive officer of Interstate Energy Corporation.  Two years after the
   combination, Liu and Stoppelmoor will step down and Davis will succeed 
   Liu as chairman.

   The new, combined organization will serve more than 850,000 electric and
   360,000 natural gas customers in Iowa, Illinois, Minnesota and Wisconsin. 
   In addition WPL Holdings, through its Heartland Development Corporation
   subsidiaries, has offices in 25 states and two foreign countries.  IES
   Diversified has non-regulated energy businesses with eight offices in six
   states and interests in a utility in New Zealand.  The new holding company
   will consist of utility and non-utility operations.

   "The combination of these companies will create significant long-term
   benefits for our employees, customers and shareholders," Liu said. 
   "Interstate Energy Corporation will be well-positioned to build on its
   strengths as a low-cost energy provider and committed community partner. 
   That strategy should generate opportunities for our employees and
   shareholders."

   "The electric utility world is changing around us and we must be ready for
   the new competition era.  This strategic combination will ensure our
   position in a competitive regional market, as well as offer us
   opportunities for better customer service and continued low rates," 
   stated Stoppelmoor.

   "I have said for some time that alliances would be a significant part of
   WPL Holdings ' strategy for the future," commented Davis.  "We intend to
   provide better customer service at competitive rates, while increasing
   shareowner value.  This combination will move us well along toward
   becoming a regionally and nationally competitive energy company."  

   The combination is subject to approval by the shareowners of all three
   companies, the utility commissions in Illinois, Iowa, Minnesota and
   Wisconsin, the Securities and Exchange Commission, the Federal Energy
   Regulatory Commission,  and the Nuclear Regulatory Commission.  The merger
   is also subject to the expiration of the applicable waiting period under
   the Hart-Scott-Rodino Antitrust Improvements Act.  It is a condition of
   closing that the parties receive an opinion of counsel to the effect that
   the exchange of stock qualifies as a tax-free transaction, and obtain
   appropriate accountant  assurances that the transaction will be accounted
   for as a pooling of interests.  Preliminary proxy materials will be filed
   with the Securities and Exchange Commission in the near future.  Based on
   optimal times for  the required regulatory approvals, the merger is
   expected to be completed by early 1997.
