   August 13 and November 14, 1997, respectively.

             4.  The description of the Company's Common Stock contained in
   Item 4 of the Company's Registration Statement on Form 8-B, dated April 1,
   1988, including any amendment or report filed for the purpose of updating

   Act of 1934, as amended, after the date of filing of this Registration
   Statement and prior to such time as the Company files a post-effective
   amendment to this Registration Statement which indicates that all
   securities offered hereby have been sold or which deregisters all
   securities then remaining unsold shall be deemed to be incorporated by
   reference in this Registration Statement and to be a part hereof from the
   date of filing of such documents.

   Item 4.   Description of Securities.

             Not applicable.

   Item 5.   Interests of Named Experts and Counsel.

             Not applicable.

   Item 6.   Indemnification of Directors and Officers.

             Pursuant to the Wisconsin Business Corporation Law and the
   Company's By-laws, directors and officers of the Company are entitled to
   mandatory indemnification from the Company against certain liabilities and
   expenses (i) to the extent such officers or directors are successful in
   the defense of a proceeding and (ii) in proceedings in which the director
   or officer is not successful in defense thereof, unless it is determined
   that the director or officer breached or failed to perform his or her
   duties to the Company and such breach or failure constituted:  (a) a
   willful failure to deal fairly with the Company or its shareowners in
   connection with a matter in which the director or officer had a material
   conflict of interest; (b) a violation of the criminal law unless the
   director or officer had reasonable cause to believe his or her conduct was
   lawful or had no reasonable cause to believe his or her conduct was
   unlawful; (c) a transaction from which the director or officer derived an
   improper personal profit; or (d) willful misconduct.  It should be noted
   that the Wisconsin Business Corporation Law specifically states that it is
   the public policy of Wisconsin to require or permit indemnification in
   connection with a proceeding involving securities regulation, as described
   therein, to the extent required or permitted as described above. 
   Additionally, under the Wisconsin Business Corporation Law, directors of
   the Company are not subject to personal liability to the Company, its
   shareowners or any person asserting rights on behalf thereof for certain
   breaches or failures to perform any duty resulting solely from their
   status as directors except in circumstances paralleling those in
   subparagraphs (a) through (d) outlined above.

             The indemnification provided by the Wisconsin Business
   Corporation Law and the Company's By-laws is not exclusive of any other
   rights to which a director or officer may be entitled.  The general effect
   of the foregoing provisions may be to reduce the circumstances which an
   officer or director may be required to bear the economic burden of the
   foregoing liabilities and expenses.

             The Company maintains a liability insurance policy for its
   directors and officers as permitted by Wisconsin law which may extend to,
   among other things, liability arising under the Securities Act of 1933, as
   amended.

   Item 7.   Exemption from Registration Claimed.

             Not Applicable.

   Item 8.   Exhibits.

             The following exhibits have been filed (except where otherwise
   indicated) as part of this Registration Statement:

    Exhibit No.                         Exhibit

    (4.1)              Interstate Energy Corporation 401(k) Savings Plan, as
                       amended to date

    (4.2)              Rights Agreement, dated as of February 22, 1989,
                       between WPL Holdings, Inc. and Morgan Shareholder
                       Services Trust Company (incorporated by reference to
                       Exhibit 4 to WPL Holdings, Inc.'s Current Report on
                       Form 8-K, dated as of February 27, 1989)

    (5)                Opinion of Foley & Lardner

    (23.1)             Consent of Arthur Andersen LLP

    (23.2)             Consent of Foley & Lardner (contained in Exhibit (5)
                       hereto)

    (24)               Powers of Attorney

             The undersigned Registrant hereby undertakes to submit the Plan,
   as amended, to the Internal Revenue Service ("IRS") in a timely manner and
   will make all changes required by the IRS in order to continue the
   qualification of the Plan under Section 401 of the Internal Revenue Code
   of 1986, as amended.

   Item 9.   Undertakings.

             (a)  The undersigned Registrant hereby undertakes:

             (1)  To file, during any period in which offers or sales are
   being made, a post-effective amendment to this Registration Statement to
   include any material information with respect to the plan of distribution
   not previously disclosed in the Registration Statement or any material
   change to such information in the Registration Statement.

             (2)  That, for the purpose of determining any liability under
   the Securities Act of 1933, each such post-effective amendment shall be
   deemed to be a new registration statement relating to the securities
   offered herein, and the offering of such securities at that time shall be
   deemed to be the initial bona fide offering thereof.

             (3)  To remove from registration by means of a post-effective
   amendment any of the securities being registered which remain unsold at
   the termination of the offering.

             (b)  The undersigned Registrant hereby undertakes that, for
   purposes of determining any liability under the Securities Act of 1933,
   each filing of the Registrant's annual report pursuant to Section 13(a) or
   Section 15(d) of the Securities Exchange Act of 1934 (and, where
   applicable, each filing of an employee benefit plan's annual report
   pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
   incorporated by reference in this Registration Statement shall be deemed
   to be a new registration statement relating to the securities offered
   herein, and the offering of such securities at that time shall be deemed
   to be the initial bona fide offering thereof.

             (c)  Insofar as indemnification for liabilities arising under
   the Securities Act of 1933 may be permitted to directors, officers and
   controlling persons of the Registrant pursuant to the foregoing
   provisions, or otherwise, the Registrant has been advised that in the
   opinion of the Securities and Exchange Commission such indemnification is
   against public policy as expressed in the Act and is, therefore,
   unenforceable.  In the event that a claim for indemnification against such
   liabilities (other than the payment by the Registrant of expenses incurred
   or paid by a director, officer or controlling person of the Registrant in
   the successful defense of any action, suit or proceeding) is asserted by
   such director, officer or controlling person in connection with the
   securities being registered, the Registrant will, unless in the opinion of
   its counsel the matter has been settled by controlling precedent, submit
   to a court of appropriate jurisdiction the question whether such
   indemnification by it is against public policy as expressed in the Act and
   will be governed by the final adjudication of such issue.

   of Wisconsin, on this 20th day of February, 1998.
