Item 5.   Other Events.

          WPL Holdings, Inc., a holding company incorporated
under the laws of the State of Wisconsin ("WPL"), IES Industries
Inc., a holding company incorporated under the laws of the State
of Iowa ("IES"), Interstate Power Company, an operating public
utility incorporated under the laws of the State of Delaware
("IPC"), and AMW Acquisition, Inc., a wholly owned subsidiary of
WPL incorporated under the laws of the State of Delaware ("AMW"),
have entered into an Agreement and Plan of Merger, dated as of
November 10, 1995 (the "Merger Agreement"), providing for (a) the
merger of IES with and into WPL, which merger will result in the
combination of WPL and IES as a single company (the "IES
Merger"), and (b) the merger of AMW with and into IPC, which
merger will result in IPC becoming a wholly owned subsidiary of
WPL (the "IPC Merger", and together with the IES Merger, the
"Merger").  The Merger, which was unanimously approved by the
Board of Directors of each of the constituent companies, is
expected to close promptly after all of the conditions to the
consummation of the Merger, including obtaining all applicable
regulatory approvals, are fulfilled or waived.  The regulatory
approval process is expected to take approximately 12 to 18
months.

          In the Merger, WPL will change its name to Interstate
Energy Corporation ("Interstate Energy") and Interstate Energy,
as the holding company of the combined enterprise, will be
registered under the Public Utility Holding Company Act of 1935,
as amended.  Interstate Energy will be the parent company of
WPL's present principal utility subsidiary, Wisconsin Power and
Light Company ("WP&LC"), IES's present utility subsidiary, IES
Utilities Inc. ("Utilities"), and IPC.  Following the Merger, the
non-utility operations of WPL and IES, Heartland Development
Corporation and IES Diversified Inc., respectively, will be
combined under one entity to manage the diversified operations of
Interstate Energy.

          Under the terms of the Merger Agreement, each
outstanding share of common stock, no par value, of IES will be
cancelled and converted into the right to receive .98 of a share
of common stock, par value $.01 per share, of Interstate Energy
(the "Interstate Energy Common Stock") and each outstanding share
of common stock, par value $3.50 per share, of IPC will be
cancelled and converted into the right to receive 1.11 shares of
Interstate Energy Common Stock.  The outstanding shares of common
stock, par value $.01 per share, of WPL will remain unchanged and
outstanding as shares of Interstate Energy Common Stock.  As of
the close of business on November 10, 1995, WPL had approximately
30.8 million common shares outstanding, IES had approximately
29.3 million common shares outstanding and IPC had approximately
9.6 million common shares outstanding.  Based on such
capitalization, the Merger will result in the common shareowners
of WPL holding 43.9% of the common equity of Interstate Energy,
the common shareowners of IES receiving 40.9% of the common
equity of Interstate Energy and the common shareowners of IPC
receiving 15.2% of the common equity of Interstate Energy.  Each
outstanding share of preferred stock, par value $50 per share, of
IPC will be unchanged as a result of the Merger and will remain
outstanding.  In this Current Report on Form 8-K, unless the
context otherwise requires, all references to Interstate Energy
Common Stock include, if applicable, the associated rights to
purchase shares of such common stock pursuant to the terms of the
Rights Agreement between WPL and Morgan Shareholder Services
Trust Company, as Rights Agent thereunder, dated as of February
22, 1989.

          The parties expect that the dividend at the effective
time of the Merger will be the dividend then being paid by WPL. 
Subsequent dividend policy will be developed by the Board of
Directors of Interstate Energy.

          The Merger is subject to customary closing conditions,
including, without limitation, the receipt of required shareowner
approvals of WPL, IES and IPC; and the receipt of all necessary
governmental approvals and the making of all necessary
governmental filings, including approvals of state utility
regulators in Illinois, Iowa, Minnesota and Wisconsin, the
approval of the Federal Energy Regulatory Commission, the
Securities and Exchange Commission (the "SEC") and the Nuclear
Regulatory Commission, and the filing of the requisite
notification with the Federal Trade Commission and the Department
of Justice under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, and the expiration of the applicable waiting
period thereunder.  The Merger is also subject to receipt of
opinions of counsel that the Merger will qualify as a tax-free
reorganization, and assurances from the parties' independent
accountants that the Merger will qualify as a pooling of
interests for accounting purposes.  In addition, the Merger is
conditioned upon the effectiveness of a registration statement to
be filed by WPL with the SEC with respect to shares of the
Interstate Energy Common Stock to be issued in the Merger and the
approval for listing of such shares on the New York Stock
Exchange.  (See Article IX of the Merger Agreement.)  It is
anticipated that shareowners will vote upon the Merger at the
upcoming annual meetings in the second quarter of 1996.

          The Merger Agreement contains certain covenants of the
parties pending the consummation of the Merger.  Generally, the
parties must carry on their businesses in the ordinary course
consistent with past practice, may not increase dividends on
common stock in excess of current levels in the case of IES and
IPC and beyond a specified limit in the case of WPL, and may not
issue any capital stock beyond certain limits.  The Merger
Agreement also contains restrictions on, among other things,
charter and bylaw amendments, acquisitions, capital expenditures,
dispositions, incurrence of indebtedness, certain increases in
employee compensation and benefits, and affiliate transactions. 
(See Article VII of the Merger Agreement.)

          The Merger Agreement provides that, after the
effectiveness of the Merger (the "Effective Time"), the corporate
headquarters and principal executive offices of Interstate Energy
and WP&LC will remain in Madison, Wisconsin, the headquarters of
Utilities will remain in Cedar Rapids, Iowa, and the headquarters
of IPC will remain in Dubuque, Iowa.  Interstate Energy's Board
of Directors, which will be divided into three classes, will
consist of a total of 15 directors, 6 of whom will be designated
by WPL, 6 of whom will be designated by IES and 3 of whom will be
designated by IPC.  Mr. Lee Liu, the current Chairman of the
Board, President and Chief Executive Officer of IES, will serve
as Chairman of the Board of Directors of Interstate Energy for a
period of two years from the Effective Time.  Mr. Wayne H.
Stoppelmoor, the current Chairman of the Board, President and
Chief Executive Officer of IPC, will serve as Vice Chairman of
the Board of Directors of Interstate Energy for a period of two
years from the Effective Time.  Mr. Erroll B. Davis, Jr., the
current President and Chief Executive Officer of WPL, will become
President and Chief Executive Officer of Interstate Energy from
the Effective Time.  Mr. Davis will also assume the position of
Chairman of the Board when Mr. Liu retires as Chairman. (See
Article VIII of the Merger Agreement.)

          The Merger Agreement may be terminated under certain
circumstances, including (i) by mutual consent of the parties;
(ii) by any party if the Merger is not consummated by May 10,
1997 (provided, however, that such termination date shall be
extended to May 10, 1998 if all conditions to closing the Merger,
other than the receipt of certain consents and/or statutory
approvals by any of the parties, have been satisfied by May 10,
1997); (iii) by any party if any of WPL's, IES's or IPC's
shareowners vote against the Merger or if any state or federal
law or court order prohibits the Merger; (iv) by a non-breaching
party if there exist breaches of any representations or
warranties contained in the Merger Agreement or in the Stock
Option Agreements (as hereinafter defined), as of the date
thereof, which breaches, individually or in the aggregate, would
result in a material adverse effect on the breaching party and
which are not cured within twenty (20) days after notice; (v) by
a non-breaching party if there occur breaches of specified
covenants in the Merger Agreement or material breaches of any
covenant or agreement in the Merger Agreement or in the Stock
Option Agreements which are not cured within (20) days after
notice; (vi) by any party if the Board of Directors of any other
party shall withdraw or adversely modify its recommendation of
the Merger or shall approve or recommend any competing
transaction; or (vii) by any party, under certain circumstances,
as a result of a third-party tender offer or business combination
proposal which such party, pursuant to its directors' fiduciary
duties, is, in the opinion of such party's counsel and after the
other parties have first been given an opportunity to make
concessions and adjustments in the terms of the Merger Agreement,
required to accept.  (See Article X of the Merger Agreement.)

          The Merger Agreement provides that if a breach
described in clause (iv) or (v) of the previous paragraph occurs,
then, if such breach is not willful, the non-breaching party or
parties will be entitled to reimbursement of its or their out-of-
pocket expenses, not to exceed $5 million to each non-breaching
party.  In the event of a willful breach, the non-breaching party
or parties will be entitled to its or their out-of-pocket
expenses (which shall not be limited to $5 million) and any
remedies it or they may have at law or in equity, and provided
that if, at the time of the breaching party's or parties' willful
breach, there shall have been a third party tender offer or
business combination proposal which shall not have been rejected
by the breaching party or parties or withdrawn by the third
party, and within two and one-half years of any termination by
the non-breaching party or parties, the breaching party or
parties accept an offer to consummate or consummates a business
combination with such third party, then such breaching party or
parties, upon the closing of such business combination, will pay
to the non-breaching party or parties an additional aggregate fee
equal to $25 million, if WPL or IES is the breaching party, or
$12.5 million, if IPC is the breaching party.  The Merger
Agreement also requires payment of an aggregate termination fee
of $25 million, if WPL or IES is the Target Party (as hereinafter
defined), or $12.5 million, if IPC is the Target Party, together
with reimbursement of out-of-pocket expenses, by one party (the
"Target Party") to the other parties in the following
circumstances:  (1) the Merger Agreement is terminated (x) as a
result of the acceptance by the Target Party of a third-party
tender offer or business combination proposal, (y) following a
failure of the shareowners of the Target Party to grant their
approval to the Merger or (z) as a result of the Target Party's
material failure to convene a shareowner meeting, distribute
proxy materials and, subject to its board of directors' fiduciary
duties, recommend the Merger to its shareowners; (2) at the time
of such termination or prior to the meeting of such party's
shareowners there shall have been a third-party tender offer or
business combination proposal which shall not have been rejected
by the Target Party or withdrawn by such third party; and (3)
within two and one-half years of any such termination described
in clause (1) above, the Target Party accepts an offer to
consummate or consummates a business combination with such third
party.  The applicable termination fee and out-of-pocket expenses
referred to in the previous sentence will be paid at the closing
of such third-party business combination.  The termination fees
payable by WPL, IES and/or IPC under the foregoing provisions
plus the aggregate amount which could be payable by WPL, IES
and/or IPC under the Stock Option Agreements may not exceed $40
million (for WPL or IES) or $20 million (for IPC) in the
aggregate.  In addition to the foregoing, if the Merger Agreement
is terminated under circumstances that give rise to the payment
of the termination fee discussed above by the Target Party
referred to above and within nine months of such termination one
of the non-terminating parties is acquired by the same third
party offeror, the sole remaining party will be entitled to (i) a
second termination fee of $25 million, if WPL or IES is the
second target party, or $12.5 million if IPC is the second target
party, on the signing of a definitive agreement relating to such
business combination, and (ii) payment of any termination fee
paid to such second target party by the original terminating
party (i.e., first Target Party) pursuant to the termination of
the Merger Agreement.  If only one party must pay expenses, or is
entitled to receive a termination fee as set forth above, such
party will pay or receive one hundred percent (100%) of the
applicable expenses or fee.  If two parties are required to pay
expenses or entitled to receive any such fee, each such party's
percentage of such expenses or fee will equal a fraction, the
numerator of which shall be, in the case of IES or IPC, the
number of shares of Interstate Energy Common Stock which would
have been issuable (on a fully diluted basis) to such party's
shareowners, or, in the case of WPL, the number of shares of
Interstate Energy Common Stock (on a fully diluted basis) that
would have been retained by its shareowners, had the effective
time of the Merger occurred at the time the Merger Agreement is
terminated, and the denominator of which will be the aggregate
number of shares of Interstate Energy Common Stock that would
have been issuable to or retained by (in either case on a fully
diluted basis) the shareowners of the two parties required to pay
expenses or entitled to receive such fee had the effective time
of the Merger occurred at the time the Merger Agreement is
terminated.  (See Article X of the Merger Agreement.)

          Concurrently with the Merger Agreement, WPL, IES and
IPC entered into reciprocal stock option agreements (the "Stock
Option Agreements") each granting the other two parties an
irrevocable option to purchase a specified percentage of up to
that number of shares of common stock of the granting company
which equals a collective aggregate of 19.9% of the number of
shares of common stock of the granting company outstanding on
November 10, 1995 at an exercise price of $30.675 per share of
WPL Common Stock, $26.7125 per share of IES Common Stock or
$28.9375 per share of IPC Common Stock, as the case may be, under
certain circumstances if the Merger Agreement becomes terminable
by one or more parties as a result of one or more other parties'
breach or as a result of one or more of the other parties
becoming the subject of a third-party proposal for a business
combination.  Any party whose option becomes exercisable (the
"Exercising Party") (i) will have the right to receive, under
certain circumstances, a cash settlement that would pay to the
Exercising Party the difference between the exercise price and
the then current market price and (ii) may request that the
granting company repurchase from it all or any portion of the
Exercising Party's option at the price specified in the Stock
Option Agreements.  (See the Stock Option Agreements.)

          Interstate Energy is expected to be the 34th-largest
investor-owned utility holding company in the United States based
on the 1994 combined revenues of WPL, IES and IPC of $1.9
billion.  It is anticipated that Interstate Energy will have a
market capitalization of approximately $2 billion (based on the
current combined market capitalization of WPL, IES and IPC) and
assets of nearly $4 billion (based on December 31, 1994 combined
asset totals).  It is expected that Interstate Energy will serve
more than 850,000 electric customers and 360,000 natural gas
customers in Iowa, Illinois, Minnesota and Wisconsin.  The
business of Interstate Energy will consist of utility operations
and various non-utility enterprises.

          A preliminary estimate indicates that the Merger will
result in net savings of approximately $700 million in costs over
10 years.

          In response to the announcement of the Merger, Standard
and Poor's Corporation ("S&P") placed its ratings of WP&LC's "AA"
rated senior secured debt, "AA-" rated preferred stock and "A-1+"
rated commercial paper on CreditWatch with negative implications. 
The ratings of Utilities' "A" rated senior secured debt, "A-"
rated preferred stock and "A-1" rated commercial paper were
placed on CreditWatch with positive implications.  The ratings of
IPC's "A+" rated senior secured debt, "A" rated senior unsecured
debt, "A" rated preferred stock and "A-1" rated commercial paper
were affirmed.  S&P indicated that if the Merger is completed,
the likely credit ratings for the senior secured debt of WP&LC,
Utilities and IPC are expected to be "A+".

          Moody's Investors Service ("Moody's") placed WP&LC's
"Aa2" rated senior secured debt, "(P)Aa2" rated senior secured 
debt shelf registration, "aa3" rated preferred stock, "(P)aa3"
rated preferred stock shelf registration and "Aa3" counterparty
rating under review for possible downgrade.  The ratings of
Utilities' "A2" rated senior secured debt, "(P)A2" rated senior
secured debt shelf registration, "A2" rated secured pollution
control bonds, "A3" unsecured pollution control bonds, "(P)A3"
rated senior unsecured debt shelf registration, "(P)Baa1" rated
junior subordinated unsecured debt shelf registration and "A3"
counterparty rating have been placed under review for possible
upgrade.  In addition, IPC's "A1" rated senior secured debt,
"(P)A1" rated senior secured debt shelf registration, "A2" rated
unsecured pollution control bonds, "a2" rated preferred stock,
"(P)a2" rated preferred stock shelf registration and "A2"
counterparty rating have been placed under review for possible
downgrade.  Moody's indicated that the "Prime-1" short term
ratings of the three companies are not under review.

          WPL, IES and IPC recognize that the divestiture of
their existing gas operations and certain non-utility operations
is a possibility under the new registered holding company
structure, but will seek approval from SEC to maintain such
businesses.  If divestiture is ultimately required, the SEC has
historically allowed companies sufficient time to accomplish
divestitures in a manner that protects shareowner value.

                           ARTICLE II

                       TREATMENT OF SHARES

          Section 2.1  Effect of the Merger on Capital Stock.  
At the Effective Time, by virtue of the Merger and without any
action on the part of any holder of any capital stock of WPL,
IES, Interstate or AMW:

          (a)  Cancellation of Certain Common Stock. 

               (i)  Each share of Common Stock, no par value, of
     IES (the "IES Common Stock") that is owned by IES, WPL or
     Interstate or any of their respective Subsidiaries (as
     hereinafter defined) shall be canceled and shall cease to
     exist, and 

              (ii)  each share of Common Stock, par value $3.50
     per share, of Interstate (the "Interstate Common Stock")
     that is owned by IES, WPL or Interstate or any of their
     respective Subsidiaries shall be canceled and shall cease to
     exist.

          (b)  Conversion of Certain Common Stock.  

               (i)  Each issued and outstanding share of IES
     Common Stock (other than shares canceled pursuant to Section
     2.1(a)(i) and IES Dissenting Shares (as hereinafter
     defined)) shall be converted into the right to receive 0.98
     (the "IES Ratio") duly authorized, validly issued, fully
     paid and nonassessable (except as otherwise provided in
     Section 180.0622(2)(b) of the WBCL) shares of Common Stock,
     par value $.01 per share, of WPL ("WPL Common Stock"),
     including, if applicable, associated rights (the "WPL
     Rights") to purchase shares of WPL Common Stock pursuant to
     the terms of that certain Rights Agreement between WPL and
     Morgan Shareholder Services Trust Company, as Rights Agent
     thereunder, dated as of February 22, 1989 (the "WPL Rights
     Agreement").  Until the Distribution Date (as defined in the
     WPL Rights Agreement) all references in this Agreement to
     the WPL Common Stock shall be deemed to include the
     associated WPL Rights.

              (ii)  Each issued and outstanding share of
     Interstate Common Stock (other than shares canceled pursuant
     to Section 2.1(a)(ii)) shall be converted into the right to
     receive 1.11 (the "Interstate Ratio") duly authorized,
     validly issued, fully paid and nonassessable (except as
     otherwise provided in Section 180.0622(2)(b) of the WBCL)
     shares of WPL Common Stock. 

             (iii)  Upon such conversions and except as otherwise
     provided in Section 2.2, all such shares of IES Common Stock
     and Interstate Common Stock shall be canceled and cease to
     exist, and each holder of a certificate formerly
     representing any such shares of IES Common Stock or
     Interstate Common Stock shall cease to have rights with
     respect thereto, except the right to receive the shares of
     WPL Common Stock to be issued in consideration therefor upon
     the surrender of such certificate in accordance with Section
     2.3 and any cash in lieu of fractional shares of WPL Common
     Stock.

          (c)  No Change in Interstate Preferred Stock.  Each
issued and outstanding share of Preferred Stock, $50 par value,
of Interstate (the "Interstate Preferred Stock") shall be
unchanged as a result of the Interstate Merger and shall remain
outstanding thereafter.

          (d)  Conversion of AMW Common Stock.  All of the shares
of Common Stock, par value $0.01 per share, of AMW (the "AMW
Common Stock") issued and outstanding immediately prior to the
Effective Time shall be converted into that number of shares of
Interstate Common Stock (as the surviving corporation in the
Interstate Merger) which shall be equivalent to the aggregate
number of shares of Interstate Common Stock (exclusive of the
shares canceled pursuant to Section 2.1(a)(ii)) issued and
outstanding immediately prior to the Effective Time.  From and
after the Effective Time, each outstanding certificate
theretofore representing shares of AMW Common Stock shall be
deemed for all purposes to evidence ownership of and to represent
the number of shares of Interstate Common Stock into which such
shares of AMW Common Stock shall have been converted.

          Section 2.2   Dissenting Shares.  

          (a)  Shares of IES Common Stock held by any holder
entitled to relief as a dissenting shareholder under Section
490.1302 of the IBCA (the "IES Dissenting Shares") shall not be
converted into the right to receive WPL Common Stock in the IES
Merger, but shall be canceled and converted into such
consideration as may be due with respect to such shares pursuant
to the applicable provisions of Sections 490.1320 through
490.1330 of the IBCA, unless and until the right of such holder
to receive fair cash value for such Dissenting Shares (as
hereinafter defined) terminates in accordance with Sections
490.1320 through 490.1330 of the IBCA.  If such right is
terminated otherwise than by the purchase of such shares by WPL,
then such shares shall cease to be Dissenting Shares and shall
represent the right to receive WPL Common Stock, as provided in
Section 2.1(b)(i).

          (b)  Shares of Interstate Preferred Stock held by any
holder entitled to relief as a dissenting shareholder under
Section 262 of the DGCL (the "Interstate Dissenting Shares," and,
collectively with the IES Dissenting Shares, the "Dissenting
Shares") shall be canceled and converted into such consideration
as may be due with respect to such shares pursuant to the
applicable provisions of Section 262 of the DGCL.  If such right
is terminated otherwise than by the purchase of such shares by
WPL, then such shares shall cease to be Dissenting Shares and
shall remain outstanding.

          Section 2.3  Issuance of New Certificates.

          (a)  Deposit with Exchange Agent.  As soon as
practicable after the Effective Time, WPL shall deposit with such
bank, trust company or other appropriate entity mutually
agreeable to WPL, IES and Interstate (the "Exchange Agent"),
certificates representing shares of WPL Common Stock required to
effect the issuances referred to in Section 2.1, together with
cash payable in respect of fractional shares pursuant to
Section 2.3(d).

          (b)  Issuance Procedures.  

               (i)  As soon as practicable after the Effective
     Time, the Exchange Agent shall mail to each holder of record
     of a certificate or certificates (the "Certificates") which
     immediately prior to the Effective Time represented
     outstanding shares of IES Common Stock or Interstate Common
     Stock, as the case may be (collectively, the "Canceled
     Common Shares"), that were canceled and became instead the
     right to receive shares of WPL Common Stock pursuant to
     Section 2.1(b) and the Plan of Merger, (A) a letter of
     transmittal (which shall specify that delivery shall be
     effected, and risk of loss and title to the Certificates
     shall pass, only upon actual delivery of the Certificates to
     the Exchange Agent), and (B) instructions for use in
     effecting the surrender of the Certificates in exchange for
     certificates representing WPL Common Stock. 

              (ii)  Upon surrender of a Certificate to the
     Exchange Agent for cancellation (or to such other agent or
     agents as may be appointed by agreement of WPL, IES and
     Interstate), together with a duly executed letter of
     transmittal and such other documents as the Exchange Agent
     shall require, the holder of such Certificate shall be
     entitled to receive a certificate representing that number
     of whole shares of WPL Common Stock which such holder has
     the right to receive pursuant to the provisions of this
     Article II and the Plan of Merger.  In the event of a
     transfer of ownership of Canceled Common Shares which is not
     registered in the transfer records of IES or Interstate, as
     the case may be, a certificate representing the proper
     number of shares of WPL Common Stock may be issued to a
     transferee if the Certificate representing such Canceled
     Common Shares is presented to the Exchange Agent,
     accompanied by all documents required to evidence and effect
     such transfer and by evidence satisfactory to the Exchange
     Agent that any applicable stock transfer taxes have been
     paid.

             (iii)  Until surrendered as contemplated by this
     Section 2.3, each Certificate shall be deemed at any time
     after the Effective Time to represent only the right to
     receive upon such surrender the certificate representing WPL
     Common Stock and cash in lieu of any fractional shares of
     WPL Common Stock contemplated by this Section 2.3.

          (c)  Distributions with Respect to Unsurrendered
Shares.  

               (i)  No dividends or other distributions declared
     or made after the Effective Time with respect to shares of
     WPL Common Stock with a record date after the Effective Time
     shall be paid to the holder of any unsurrendered Certificate
     with respect to the shares of WPL Common Stock represented
     thereby and no cash payment in lieu of fractional shares
     shall be paid to any such holder pursuant to Section 2.3(d)
     until the holder of record of such Certificate (or a
     transferee as described in Section 2.3(b)) shall surrender
     such Certificate. 

              (ii)  Subject to the effect of unclaimed property,
     escheat and other applicable laws, following surrender of
     any such Certificate, there shall be paid to the record
     holders (or a transferee as described in Section 2.3(b)) of
     the certificates representing whole shares of WPL Common
     Stock issued in consideration therefor, without interest, 

                    (A)  at the time of such surrender, the
          amount of cash in lieu of a fractional share of WPL
          Common Stock to which such holder (or transferee) is
          entitled pursuant to Section 2.3(d) and the amount of
          dividends or other distributions with a record date
          after the Effective Time which theretofore became
          payable but which were not paid by reason of Section
          2.3(c)(i) with respect to such whole shares of WPL
          Common Stock, and 

                    (B)  at the appropriate payment date, the
          amount of dividends or other distributions with a
          record date after the Effective Time but prior to
          surrender and a payment date subsequent to surrender
          payable with respect to such whole shares of WPL Common
          Stock.

          (d)  No Fractional Securities.  

               (i)  Notwithstanding any other provision of this
     Agreement, no certificates or scrip representing fractional
     shares of WPL Common Stock shall be issued upon the
     surrender for exchange of Certificates and such fractional
     shares shall not entitle the owner thereof to vote as, or to
     any other rights of, a holder of WPL Common Stock. 

              (ii)  A holder of IES Common Stock or Interstate
     Common Stock who would otherwise have been entitled to
     receive a fractional share of WPL Common Stock shall be
     entitled to receive a cash payment in lieu of such
     fractional share in an amount equal to the product (rounded
     to the nearest cent) of such fraction (rounded to the
     nearest thousandth) multiplied by the average of the last
     reported sales price, regular way, per share of WPL Common
     Stock, on the New York Stock Exchange ("NYSE") Composite
     Tape for the ten business days prior to and including the
     last business day prior to the Effective Time on which WPL
     Common Stock was traded on the NYSE, without any interest
     thereon.

          (e)  Closing of Common Stock Transfer Books.  From and
after the Effective Time, the stock transfer books of IES and
Interstate with respect to shares of IES Common Stock and
Interstate Common Stock issued and outstanding prior to the
Effective Time shall be closed and no transfer of any such shares
shall thereafter be made.  If, after the Effective Time,
Certificates are presented to WPL or Interstate, they shall be
canceled and exchanged for certificates representing the
appropriate number of shares of WPL Common Stock as provided in
this Section 2.3.

          (f)  Termination of Exchange Agent.  Any certificates
representing WPL Common Stock deposited with the Exchange Agent
pursuant to Section 2.3(a) and not exchanged within one year
after the Effective Time pursuant to this Section 2.3 shall be
returned by the Exchange Agent to the Company, which shall
thereafter act as Exchange Agent.  All funds held by the Exchange
Agent for payment to the holders of unsurrendered Certificates
and unclaimed at the end of one year from the Effective Time
shall be returned to the Company, after which time any holder of
unsurrendered Certificates shall look as a general creditor only
to the Company for payment of such funds to which such holder may
be due, subject to applicable law.  The Company shall not be
liable to any person for such shares or funds delivered to a
public official pursuant to any applicable abandoned property,
escheat or similar law.

Disclosure Schedule contains a true and complete list of each
employee benefit plan, program or arrangement covering employees,
former employees or directors of WPL and each of the WPL
Subsidiaries or their beneficiaries, or providing benefits to
such persons in respect of services provided to any such entity,

respects in compliance with, all applicable laws, rules and
regulations governing each such plan, including, without
limitation, ERISA and the Code, except for any violations that,

foreseen, would not, give rise to a WPL Material Adverse Effect. 
Each WPL Benefit Plan intended to provide for the deferral of
income, the reduction of salary or other compensation, or to
afford other income tax benefits, complies in all material
respects with the requirements of the applicable provisions of
the Code or other laws, rules and regulations required to provide

ERISA or any other applicable law (including, without limitation,
any liability of any kind whatsoever, whether direct or indirect,
contingent, inchoate or otherwise, to any such plan or the
Pension Benefit Guaranty Corporation (the "PBGC")), or under any
indemnity agreement to which WPL is subject, which liability,

or Part 6 of Title I of ERISA or coverage which expires at the
end of the calendar month following such event.

          (f)  Documents made Available.  WPL has made available
to IES and Interstate a true and correct copy of each collective

     transaction contemplated by this Agreement will not (either
     alone or upon the occurrence of any additional or further
     acts or events) result in any 

                    (A)  payment (whether of severance pay or 
          otherwise) becoming due from WPL or any of the WPL
          Subsidiaries to any officer, employee, former employee
          or director thereof or to the trustee under any "rabbi
          trust" or similar arrangement that would not have been
          paid without regard to such consummation or
          announcement, or 

                    (B)  benefit under any WPL Benefit Plan being
          established or becoming accelerated, vested or payable;
          and

              (ii)  neither WPL nor any of the WPL Subsidiaries
     is a party to

     operations which WPL or any of the WPL Subsidiaries owns,
     leases or manages, in whole or in part.

          (d)  Releases.  To the knowledge of WPL, there have not
been any material Releases (as hereinafter defined) of any
Hazardous Material (as hereinafter defined) that would be
reasonably likely to form the basis of any material Environmental
Claim against WPL or any of the WPL Subsidiaries, or against any
person or entity whose liability for any material Environmental
Claim WPL or any of the WPL Subsidiaries has or may have retained
or assumed either contractually or by operation of law.

          (e)  Predecessors.  To the knowledge of WPL, with
respect to any predecessor of WPL or any of the WPL Subsidiaries,
there is no material Environmental Claim pending or threatened,
and there has been no Release of Hazardous Materials that would
be reasonably likely to form the basis of any material
Environmental Claim.

          (f)  Disclosure.  To WPL's knowledge, WPL has disclosed
to each of IES and Interstate all material facts which WPL
reasonably believes form the basis of a material Environmental
Claim arising from 

               (i) the cost of WPL pollution control equipment
     currently required or known to be required in the future; 

               (ii) current WPL remediation costs or WPL
     remediation costs known to be required in the future; or 

               (iii) any other environmental matter affecting WPL
     or the WPL Subsidiaries or WPL Joint Ventures.

          (g)  As used in this Agreement:

               (i)  "Environmental Claim" means any and all
     administrative, regulatory or judicial actions, suits,

          Subsidiaries or WPL Joint Ventures (for purposes of
          this Section 4.11), or by IES or any of the IES

                    (B)  circumstances forming the basis of any
          violation, or alleged violation, of any Environmental
          Law; or

                    (C)  any and all claims by any third party
          seeking damages, contribution, indemnification, cost
          recovery, compensation or injunctive relief resulting
          from the presence or Release of any Hazardous
          Materials;

              (ii)  "Environmental Laws" means all Federal, state
     and local laws, rules and regulations relating to pollution,

     which are now defined as or included in the definition of
     "hazardous substances," "hazardous wastes," "hazardous
     materials," "extremely hazardous wastes," "restricted
     hazardous wastes," "toxic substances," "toxic pollutants,"
     or words of similar import, under any Environmental Law; and
     (c) any other chemical, material, substance or waste,
     exposure to which is now prohibited, limited or regulated
     under any Environmental Law in a jurisdiction in which WPL
     or any of the WPL Subsidiaries or WPL Joint Ventures
     operates (for purposes of this Section 4.11) or in which IES
     or any of the IES Subsidiaries or IES Joint Ventures
     operates (for purposes of Section 5.11) or in which
     Interstate or any of the Interstate Subsidiaries or

          Section 4.12  Regulation as a Utility.  (a) WP&LC is
regulated as a public utility in the State of Wisconsin and in no
other state.  WP&LC's Subsidiary, South Beloit Water, Gas and
Electric Company, an Illinois corporation, is a public utility
supplying electric, gas and water service, principally in
Winnebago County, Illinois.  Except as set forth in Section 4.12
of the WPL Disclosure Schedule, neither WPL nor any "subsidiary
company" or "affiliate" of WPL is subject to regulation as a
public utility or public service company (or similar designation)
by any other state in the United States or any foreign country. 
WPL is an exempt holding company under Section 3(a)(1) of the
1935 Act.

          (b) As used in this Section 4.12 and in Sections 5.12
and 6.12, the terms "subsidiary company" and "affiliate" shall
have the respective meanings ascribed to them in the 1935 Act.

          Section 4.13  Vote Required.  The approval by the
holders of a majority of the votes entitled to be cast by all
holders of WPL Common Stock (the "WPL Shareholders' Approval") to
approve the IES Merger, the issuance of the shares of WPL Common
Stock in the Merger and the charter amendments as described in
Section 8.19 of the WPL Disclosure Schedule is the only vote of
the holders of any class or series of the capital stock of WPL
required for any of the transactions contemplated by this
Agreement or the Stock Option Agreements to which WPL is a party;
provided, however, that the approval of shareholders of WPL may
be required for the repurchase of shares of WPL Common Stock
pursuant to Section 8(a) of each of the WPL/IES and
WPL/Interstate Stock Option Agreements under circumstances where
Section 180.1134 of the WBCL would be applicable.

          Section 4.14  Accounting Matters. 

          (a)  Neither WPL nor, to WPL's knowledge, any of its
Affiliates (as hereinafter defined) has taken or agreed to take
any action that would prevent WPL from accounting for the
transactions to be effected pursuant to this Agreement as a
pooling of interests in accordance with GAAP and applicable SEC
regulations.  

          (b)  As used in this Agreement (except as specifically
otherwise defined):

               (i)  "Affiliate" means, as to any person, any
     other person which directly or indirectly controls, or is
     under common control with, or is controlled by, such person;
     and

              (ii) "control" (including, with its correlative
     meanings, "controlled by" and "under common control with")
     means possession, directly or indirectly, of power to direct
     or cause the direction of management or policies (whether
     through ownership of securities or partnership or other
     ownership interests, by contract or otherwise).

          Section 4.15  Applicability of Certain Provisions of
Wisconsin Law, Etc.  Assuming the representations and warranties
of IES and Interstate made in Sections 5.18 and 6.18,
respectively, are correct, none of the "control share voting"
provisions of Section 180.1150 of the WBCL, the "business
combination" provisions of Sections 180.1140 to 180.1144 of the
WBCL, the "fair price" provisions of Sections 180.1130 to
180.1133 of the WBCL, or any other takeover related provisions of
the WBCL (or, to the knowledge of WPL, any other similar state
statute) or the Restated Articles of Incorporation or By-laws of
WPL, are applicable to the transactions contemplated by this
Agreement, including the granting or exercise of the WPL/IES and
WPL/Interstate Stock Option Agreements (except as set forth in
Section 4.15 of the WPL Disclosure Schedule).

          Section 4.16  Opinion of Financial Advisor.  As of the
date hereof, WPL has received the opinion of Merrill Lynch & Co.
("Merrill"), to the effect that, as of the date hereof, the IES
Ratio and the Interstate Ratio are fair to WPL from a financial
point of view.

          Section 4.17  Insurance.  Except as set forth in
Section 4.17 of the WPL Disclosure Schedule, each of WPL and the
WPL Subsidiaries is, and has been continuously since January 1,
1990, insured with financially responsible insurers in such
amounts and against such risks and losses as are customary in all
material respects for companies conducting the business conducted
by WPL and the WPL Subsidiaries during such time period.  Except
as set forth in Section 4.17 of the WPL Disclosure Schedule,
neither WPL nor any of the WPL Subsidiaries has received any
notice of cancellation or termination with respect to any
material insurance policy of WPL or any of the WPL Subsidiaries. 
The insurance policies of WPL and each of the WPL Subsidiaries
are valid and enforceable policies in all material respects.

          Section 4.18  Ownership of IES and Interstate Common
Stock.  Except as set forth in Section 4.18 of the WPL Disclosure
Schedule, and except pursuant to the terms of the IES/WPL Stock
Option Agreement and the Interstate/WPL Stock Option Agreement,
WPL does not "beneficially own" (as such term is defined for
purposes of Section 13(d) of the Exchange Act) any shares of IES
Common Stock or Interstate Common Stock.

          Section 4.19  WPL Rights Agreement.  Assuming the
accuracy of the representations contained in Sections 5.18 and
6.18, the consummation of the transactions contemplated by this
Agreement will not result in the triggering of any right or
entitlement of WPL shareholders under the WPL Rights Agreement.

          Section 4.20  Operations of Nuclear Power Plant. 
Except as set forth in Section 4.20 of the WPL Disclosure
Schedule, the operations of the Kewaunee Nuclear Facility
("Kewaunee") owned by WPL (together with Wisconsin Public Service
Corporation ("WPS") and Madison Gas & Electric Company, as
tenants in common) and operated by WPS, have at all times been
conducted in compliance with applicable health, safety,
regulatory and other legal requirements, except where the failure
to be in compliance in the aggregate does not, and insofar as can
reasonably be foreseen, would not, have a WPL Material Adverse
Effect.  Kewaunee maintains emergency plans designed to respond
to an unplanned release from Kewaunee of radioactive materials
into the environment.  Customary liability insurance consistent
with industry practice and consistent with WPL's view of the
risks inherent in the operation of a nuclear power facility
currently exists with respect to Kewaunee.  Plans for the
decommissioning of Kewaunee and for the short-term storage of
spent nuclear fuel conform with the requirements of applicable
law, and such plans have at all times been funded consistently
with budget projections for such plans.

in which the nature of its business or the ownership or leasing
of its assets and properties makes such qualification necessary,

(financial or otherwise), or the results of operations of IES and
the IES Subsidiaries taken as a whole or on the consummation of
the transaction contemplated hereby (an "IES Material Adverse
Effect").

and the applicable IES Required Statutory Approvals (as
hereinafter defined), to consummate the transactions contemplated
hereby or thereby.  The execution and delivery of this Agreement
and the IES/WPL and IES/Interstate Stock Option Agreements and
the consummation by IES of the transactions contemplated hereby
and thereby have been duly authorized by all necessary corporate
action on the part of IES, subject to obtaining the applicable
IES Shareholders' Approval.  Each of this Agreement and the
IES/WPL and IES/Interstate Stock Option Agreements has been duly
and validly executed and delivered by IES and, assuming the due
authorization, execution and delivery hereof and thereof by the
other signatories hereto and thereto, constitutes the valid and
binding obligation of IES enforceable against it in accordance
with its terms, except as may be limited by applicable
bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditors' rights generally, and
except that the availability of equitable remedies, including
specific performance, may be subject to the discretion of any
court before which any proceeding therefor may be brought.

          (b)  Non-contravention.  Except as set forth in
Section 5.4(b) of the IES Disclosure Schedule, the execution and
delivery of this Agreement and the IES/WPL and IES/Interstate
Stock Option Agreements by IES do not, and the consummation of
the transactions contemplated hereby or thereby will not, result
in a Violation pursuant to any provisions of:

               (i)  the Articles of Incorporation, By-laws or
     similar governing documents of IES or any of the IES
     Subsidiaries or the IES Joint Ventures;

     obligation or agreement of any kind to which IES or any of
     the IES Subsidiaries or IES Joint Ventures is a party or by
     which it or any of its properties or assets may be bound or
     affected,

excluding from the foregoing clauses (ii) and (iii) such
violations which, in the aggregate do not, and insofar as
reasonably can be foreseen, would not, have an IES Material
Adverse Effect.

          (c)  Statutory Approvals.  No declaration, filing or
registration with, or notice to or authorization, consent or
approval of, any Governmental Authority is necessary for the
execution and delivery of this Agreement or the IES/WPL and
IES/Interstate Stock Option Agreements by IES or the consummation

as described in Section 5.4(c) of the IES Disclosure Schedule
(the "IES Required Statutory Approvals", it being understood that
references in this Agreement to "obtaining" such IES Required
Statutory Approvals shall mean making such declarations, filings
or registrations; giving such notices; obtaining such
authorizations, consents or approvals; and having such waiting
periods expire as are necessary to avoid a violation of law).

          (d)  Compliance.

               (i)  Except as set forth in Section 5.4(d),
     Section 5.10 or Section 5.11 of the IES Disclosure Schedule,

     statute, order, rule, regulation, ordinance or judgment
     (including, without limitation, any applicable environmental
     law, ordinance or regulation) of any Governmental Authority,

     insofar as reasonably can be foreseen, would not, have an
     IES Material Adverse Effect.

              (ii)  Except as set forth in Section 5.4(d) or in
     Section 5.11 of the IES Disclosure Schedule, IES and the IES
     Subsidiaries and IES Joint Ventures have all Permits
     necessary to conduct their businesses as presently
     conducted, except those the failure of which to obtain, in
     the aggregate do not, and insofar as reasonably can be
     foreseen, would not, have an IES Material Adverse Effect. 

             (iii)  Except as set forth in Section 5.4(d) of the
     IES Disclosure Schedule, each of IES and the IES
     Subsidiaries and IES Joint Ventures is not in breach,
     violation, or default in the performance or observance of
     any term or provision of, and no event has occurred which,
     with lapse of time or action by a third party, could result
     in a default under,

               (A) its Articles of Incorporation or By-laws, or

               (B) any contract, commitment, agreement,
          indenture, mortgage, loan agreement, note, lease, bond,
          license, approval or other instrument to which it is a
          party or by which it is bound or to which any of its
          property is subject, except for breaches, violations or
          defaults which, in the aggregate do not, and insofar as
          reasonably can be foreseen, would not, have an IES
          Material Adverse Effect.

          Section 5.5  Reports and Financial Statements.  

          WP\  The filings required to be made by IES and the IES
Subsidiaries since January 1, 1992 under the Securities Act, the
Exchange Act, the 1935 Act, the Power Act, the Atomic Energy Act
and applicable state laws and regulations have been filed with
the SEC, the FERC, the NRC, the DOE or any appropriate state
public utilities commission, as the case may be, including all
forms, statements, reports, agreements (oral or written) and all
documents, exhibits, amendments and supplements appertaining
thereto, and complied, as of their respective dates, in all
material respects with all applicable requirements of the
appropriate statute and the rules and regulations thereunder.  

          (b)  IES has made available to WPL and Interstate a
true and complete copy of each form, report, schedule,
registration statement and definitive proxy statement filed by
each of IES and Utilities with the SEC since January 1, 1992 (as
such documents have since the time of their filing been amended
or supplemented, the "IES SEC Reports") and each other filing
described in Section 5.5(a).  As of their respective dates, the
IES SEC Reports did not contain any untrue statement of a
material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not
misleading.

          (c)  The audited consolidated financial statements and
unaudited interim financial statements of IES and Utilities, as
the case may be, included in the IES SEC Reports (collectively,
the "IES Financial Statements") have been prepared in accordance
with GAAP (except as may be indicated therein or in the notes
thereto and except with respect to unaudited statements as
permitted by Form 10-Q under the Exchange Act) and fairly present
in all material respects the financial position of IES or
Utilities, as the case may be, as of the dates thereof and the
results of its operations and cash flows for the periods then
ended, subject, in the case of the unaudited interim financial
statements, to normal, recurring audit adjustments.  

          (d)  True, accurate and complete copies of the Restated
Articles of Incorporation and By-laws of IES, as in effect on the
date hereof, are included (or incorporated by reference) in the
IES SEC Reports.

          Section 5.6  Absence of Certain Changes or Events.
Except as disclosed in the IES SEC Reports filed prior to the
date hereof or as set forth in Section 5.6 of the IES Disclosure
Schedule, since December 31, 1994, IES and each of the IES
Subsidiaries and IES Joint Ventures have conducted their
businesses only in the ordinary course of their respective
businesses consistent with past practice and there has not been,
and no facts or conditions exist (other than facts or conditions
of general applicability to electric utility companies in the
region in which WPL, IES and Interstate operate) which, in the
aggregate have or, insofar as reasonably can be foreseen, would
have, an IES Material Adverse Effect.

          (m)  Tax Sharing Agreements.  Neither IES nor any IES

          (n)  Code Section 280G.  Except as set forth in Section
5.9(n) of the IES Disclosure Schedule, neither IES nor any of the
IES Subsidiaries is a party to any agreement, contract, or
arrangement that could result, on account of the transactions
contemplated hereunder, separately or in the aggregate, in the
payment of any "excess parachute payments" within the meaning of
Section 280G of the Code.

          (o)  Liability for Others.  None of IES or any of the
IES Subsidiaries has any liability for Taxes of any person other
than IES and the IES Subsidiaries (i) under Treasury Regulations
Section 1.1502-6 (or any similar provision of state, local or
foreign law) as a transferee or successor, (ii) by contract, or
(iii) otherwise.

          Section 5.10  Employee Matters; ERISA.

          (a)  Benefit Plans.  Section 5.10(a) of the IES
Disclosure Schedule contains a true and complete list of each
employee benefit plan, program or arrangement covering employees,
former employees or directors of IES and each of the IES
Subsidiaries or their beneficiaries, or providing benefits to
such persons in respect of services provided to any such entity,
including, but not limited to, employee benefit plans within the
meaning of Section 3(3) of ERISA and any severance or change in
control agreement (collectively, the "IES Benefit Plans").  For
the purposes of this Section 5.10 only, the term "IES" shall be
deemed to include the predecessors of such company.

          (b)  Contributions.  Except as set forth in Section
5.10(b) of the IES Disclosure Schedule, all material
contributions and other payments required to be made by IES or
any of the IES Subsidiaries to any IES Benefit Plan (or to any
person pursuant to the terms thereof) have been made or the
amount of such payment or contribution obligation has been
reflected in the IES Financial Statements.

          (c)  Qualification; Compliance.  Except as set forth in
Section 5.10(c) of the IES Disclosure Schedule, each of the IES
Benefit Plans intended to be "qualified" within the meaning of
Section 401(a) of the Code has been determined by the IRS to be
so qualified, and, to the knowledge of IES, no circumstances
exist that are reasonably expected by IES to result in the
revocation of any such determination.  IES is in compliance in
all respects with, and each of the IES Benefit Plans is and has
been operated in all respects in compliance with, all applicable
laws, rules and regulations governing each such plan, including,
without limitation, ERISA and the Code, except for any violations
that, in the aggregate do not, and insofar as reasonably can be
foreseen, would not, give rise to an IES Material Adverse Effect. 
Each IES Benefit Plan intended to provide for the deferral of
income, the reduction of salary or other compensation, or to
afford other income tax benefits, complies in all material
respects with the requirements of the applicable provisions of
the Code or other laws, rules and regulations required to provide
such income tax benefits.

          (d)  Liabilities.  With respect to the IES Benefit
Plans, individually and in the aggregate, no event has occurred,
and, to the knowledge of IES, there does not now exist any
condition or set of circumstances that could subject IES or any
of the IES Subsidiaries to any liability arising under the Code,
ERISA or any other applicable law (including, without limitation,
any liability of any kind whatsoever, whether direct or indirect,
contingent, inchoate or otherwise, to any such plan or the PBGC),
or under any indemnity agreement to which IES is subject, which
liability, excluding liability for PBGC premiums, benefit claims
and funding obligations payable in the ordinary course, has, or
insofar as reasonably can be foreseen, would have, an IES
Material Adverse Effect.

          (e)  Welfare Plans.  Except a set forth in Section
5.10(e) of the IES Disclosure Schedule, none of the IES Benefit
Plans that are "welfare plans" within the meaning of Section 3(1)
of ERISA, provides for any benefits payable to or on behalf of
any employee or director after termination of employment or
service, as the case may be, other than elective continuation
coverage required to be provided under Section 4980B of the Code
or Part 6 of Title I of ERISA or coverage which expires at the
end of the calendar month following such event.

          (f)  Documents made Available.  IES has made available
to WPL and Interstate a true and correct copy of each collective
bargaining agreement to which IES or any of the IES Subsidiaries
is a party or under which IES or any of the IES Subsidiaries has
obligations and, with respect to each IES Benefit Plan, where
applicable, 

               (i)  such plan and summary plan description,

              (ii)  the most recent annual report filed with the
     IRS, 

             (iii)  each related trust agreement, insurance
     contract, service provider or investment management
     agreement (including all amendments to each such document),

              (iv)  the most recent determination of the IRS with
     respect to the qualified status of such IES Benefit Plan,
     and 

               (v)  the most recent actuarial report or
     valuation.

          (g)  Payments Resulting from Merger.  Except as set
forth in Section 5.10(g) of the IES Disclosure Schedule:  

               (i)  The consummation or announcement of any
     transaction contemplated by this Agreement will not (either
     alone or upon the occurrence of any additional or further
     acts or events) result in any 

                    (A)  payment (whether of severance pay or 
     otherwise) becoming due from IES or any of the IES
     Subsidiaries to any officer, employee, former employee or
     director thereof or to the trustee under any "rabbi trust"
     or similar arrangement that would not have been paid without
     regard to such consummation or announcement or 

                    (B)  benefit under any IES Benefit Plan being
established or becoming accelerated, vested or payable; and

              (ii)  neither IES nor any of the IES Subsidiaries
     is a party to

                    (A) any management, employment, deferred
          compensation, severance (including any payment, right
          or benefit resulting from a change in control), bonus
          or other contract for personal services with any
          officer, director or employee,

                    (B) any consulting contract with any person
          who prior to entering into such contract was a director
          or officer of IES, or

                    (C) any material plan, agreement, arrangement
          or understanding similar to any of the foregoing.

          (h)  Labor Agreements.  Except as set forth in Section
5.10(h) of the IES Disclosure Schedule, as of the date hereof,
neither IES nor any of the IES Subsidiaries is a party to any
collective bargaining agreement or other labor agreement with any
union or labor organization.  To the knowledge of IES, as of the
date hereof, there is no current union representation question
involving employees of IES or any of the IES Subsidiaries, nor
does IES know of any activity or proceeding of any labor
organization (or representative thereof) or employee group to
organize any such employees.  Except as disclosed in the IES SEC
Reports filed prior to the date hereof or in Section 5.10(h) of
the IES Disclosure Schedule,

               (i) there is no material unfair labor practice,
     employment discrimination or other complaint against IES or
     any of the IES Subsidiaries pending, or to the knowledge of
     IES, threatened, 

               (ii) there is no strike, lockout or material
     dispute, slowdown or work stoppage pending, or to the
     knowledge of IES, threatened, against or involving IES or
     any of the IES Subsidiaries, and

               (iii) there is no material proceeding, claim,
     suit, action or governmental investigation pending or, to
     the knowledge of IES, threatened, in respect of which any
     director, officer, employee or agent of IES or any of the
     IES Subsidiaries is or may be entitled to claim
     indemnification from IES or such IES Subsidiary pursuant to
     their respective Articles of Incorporation or By-laws.

          Section 5.11  Environmental Protection.  Except as set
forth in Section 5.11 of the IES Disclosure Schedule or in the
IES SEC Reports filed prior to the date hereof:

          (a)  Compliance.  

               (i)  Each of IES and the IES Subsidiaries and IES
     Joint Ventures is in compliance with all applicable
     Environmental Laws, except where the failure to be in
     compliance, in the aggregate does not, and insofar as
     reasonably can be foreseen, would not, have a IES Material
     Adverse Effect; and 

               (ii) neither IES nor any of the IES Subsidiaries
     and IES Joint Ventures has received any communication
     (written or oral) from any person or Governmental Authority
     that alleges that IES or any of the IES Subsidiaries and IES
     Joint Ventures is not in such compliance with applicable
     Environmental Laws.

          (b)  Environmental Permits.  Each of IES and the IES
Subsidiaries has obtained all Environmental Permits necessary for
the construction of their facilities and the conduct of their
operations, as applicable, and all such Environmental Permits are
in good standing or, where applicable, a renewal application has
been timely filed and is pending agency approval, and IES and the
IES Subsidiaries are in compliance with all terms and conditions
of the Environmental Permits, except where the failure to be in
such compliance, in the aggregate does not, and insofar as
reasonably can be foreseen, would not, have an IES Material
Adverse Effect.

          (c)  Environmental Claims.  There is no material
Environmental Claim pending 

               (i) against IES or any of the IES Subsidiaries or
     IES Joint Ventures, 

               (ii) against any person or entity whose liability
     for any Environmental Claim IES or any of the IES
     Subsidiaries has or may have retained or assumed either
     contractually or by operation of law, or 

               (iii) against any real or personal property or
     operations which IES or any of the IES Subsidiaries owns,
     leases or manages, in whole or in part.

          (d)  Releases.  To the knowledge of IES, there have not
been any material Releases of any Hazardous Material that would
be reasonably likely to form the basis of any material
Environmental Claim against IES or any of the IES Subsidiaries,
or against any person or entity whose liability for any material
Environmental Claim IES or any of the IES Subsidiaries has or may
have retained or assumed either contractually or by operation of
law.

          (e)  Predecessors.  To the knowledge of IES, with
respect to any predecessor of IES or any of the IES Subsidiaries,
there is no material Environmental Claim pending or threatened,
and there has been no Release of Hazardous Materials that would
be reasonably likely to form the basis of any material
Environmental Claim.

          (f)  Disclosure.  To IES's knowledge, IES has disclosed
to each of WPL and Interstate all material facts which IES
reasonably believes form the basis of a material Environmental
Claim arising from 

               (i) the cost of IES pollution control equipment
     currently required or known to be required in the future; 

               (ii) current IES remediation costs or IES
     remediation costs known to be required in the future; or

               (iii) any other environmental matter affecting IES
     or the IES Subsidiaries or IES Joint Ventures.

          Section 5.12  Regulation as a Utility.  Utilities is
regulated as a public utility in the State of Iowa and in no
other state.  Except as set forth in Section 5.12 of the IES
Disclosure Schedule, neither IES nor any "subsidiary company" or
"affiliate" of IES is subject to regulation as a public utility
or public service company (or similar designation) by any other
state in the United States or any foreign country.  IES is an
exempt holding company under Section 3(a)(1) of the 1935 Act.

          Section 5.13  Vote Required.  The approval by the
holders of a majority of the votes entitled to be cast by all
holders of IES Common Stock (the "IES Shareholders' Approval") to
approve the IES Merger, is the only vote of the holders of any
class or series of capital stock of IES required for any of the
transactions required by this Agreement or the Stock Option
Agreements to which IES is a party.

          Section 5.14  Accounting Matters.  Neither IES nor, to
IES's knowledge, any of its Affiliates has taken or agreed to
take any action that would prevent IES from accounting for the
transactions to be effected pursuant to this Agreement as a
pooling of interests in accordance with GAAP and applicable SEC
regulations.  

          Section 5.15  Applicability of Certain Iowa Law, Etc. 
Assuming the representations and warranties of WPL and Interstate
made in Sections 4.18 and 6.18, respectively, are correct, none
of the "fair price" provisions of Section 502.214.7 of the IBCA,
or any other takeover related provisions of the IBCA (or, to the
knowledge of IES, any other similar state statute) or the
Restated Articles of Incorporation or By-laws of IES is
applicable to the transaction contemplated by this Agreement,
including the granting or exercise of the IES/WPL and
IES/Interstate Stock Option Agreements (except as set forth on
Schedule 5.15 of the IES Disclosure Schedule). 

          Section 5.16  Opinion of Financial Advisor.  As of the
date hereof, IES has received the opinion of Morgan Stanley & Co.
Incorporated ("Morgan"), to the effect that, as of the date
hereof, the IES Ratio, taking into account the Interstate Ratio,
is fair from a financial point of view to the holders of IES
Common Stock.

          Section 5.17  Insurance.  Except as set forth in
Section 5.17 of the IES Disclosure Schedule, each of IES and the
IES Subsidiaries is, and has been continuously since January 1,
1990, insured with financially responsible insurers in such
amounts and against such risks and losses as are customary in all
material respects for companies conducting the business conducted
by IES and the IES Subsidiaries during such time period.  Except
as set forth in Section 5.17 of the IES Disclosure Schedule,
neither IES nor any of the IES Subsidiaries has received any
notice of cancellation or termination with respect to any
material insurance policy of IES or any of the IES Subsidiaries. 
The insurance policies of IES and each of the IES Subsidiaries
are valid and enforceable policies in all material respects.

          Section 5.18  Ownership of WPL and Interstate Common
Stock.  Except as set forth in Section 5.18 of the IES Disclosure
Schedule, and except pursuant to the terms of the WPL/IES Stock
Option Agreement and the Interstate/IES Stock Option Agreement,
IES does not "beneficially own" (as such term is defined for
purposes of Section 13(d) of the Exchange Act) any shares of WPL
Common Stock or Interstate Common Stock.

          Section 5.19  IES Rights Agreement.  Assuming the
accuracy of the representations contained in Sections 4.18 and
6.18, the consummation of the transactions contemplated by this
Agreement will not result in the triggering of any right or
entitlement of IES shareholders under the Rights Agreement, dated
as of November 6, 1991, between IES and IES, as rights agent (the
"IES Rights Agreement").

          Section 5.20  Operations of Nuclear Power Plant. 
Except as set forth in Section 5.20 of the IES Disclosure
Schedule, the operations of the Duane Arnold Energy Center
("DAEC") owned by IES (together with Central Iowa Power
Cooperative and Cornbelt Power Cooperative, as tenants in common)
and operated by IES, have at all times been conducted in
compliance with applicable health, safety, regulatory and other
legal requirements, except where the failure to be in compliance
in the aggregate does not, and insofar as can reasonably be
foreseen, would not, have an IES Material Adverse Effect.  DAEC
maintains emergency plans designed to respond to an unplanned
release from DAEC of radioactive materials into the environment. 
Customary liability insurance consistent with industry practice
and consistent with IES's view of the risks inherent in the
operation of a nuclear power facility currently exists with
respect to DAEC.  Plans for the decommissioning of DAEC and for
the short-term storage of spent nuclear fuel conform with the
requirements of applicable law, and such plans have at all times
been funded consistently with budget projections for such plans.  
 

                           ARTICLE VI

business in each respective jurisdiction in which the nature of
its business or the ownership or leasing of its assets and
properties makes such qualification necessary, other than in such
jurisdictions where the failure to be so qualified and in good
standing would not, when taken together with all other such
failures, have a material adverse effect on the business,
operations, properties, assets, condition (financial or
otherwise), or the results of operations of Interstate and the
Interstate Subsidiaries taken as a whole or on the consummations
of the transactions contemplated hereby (an "Interstate Material
Adverse Effect").

subject to the applicable Interstate Shareholders' Approval (as
hereinafter defined) and the applicable Interstate Required
Statutory Approvals (as hereinafter defined), to consummate the
transactions contemplated hereby or thereby.  The execution and
delivery of this Agreement and the Interstate/WPL and
Interstate/IES Stock Option Agreements and the consummation by
Interstate of the transactions contemplated hereby and thereby
have been duly authorized by all necessary corporate action on
the part of Interstate, subject to obtaining the applicable
Interstate Shareholders' Approval.  Each of this Agreement and
the Interstate/WPL and Interstate/IES Stock Option Agreements has
been duly and validly executed and delivered by Interstate and,
assuming the due authorization, execution and delivery hereof and
thereof by the other signatories hereto and thereto, constitutes
the valid and binding obligation of Interstate enforceable
against it in accordance with its terms, except as may be limited
by applicable bankruptcy, insolvency, reorganization or other
similar laws affecting the enforcement of creditors' rights
generally, and except that the availability of equitable
remedies, including specific performance, may be subject to the
discretion of any court before which any proceeding therefor may
be brought.

          (b)  Non-contravention.  Except as set forth in
Section 6.4(b) of the Interstate Disclosure Schedule, the
execution and delivery of this Agreement and the Interstate/WPL
and Interstate/IES Stock Option Agreements by Interstate do not,
and the consummation of the transactions contemplated hereby or
thereby will not, result in a Violation pursuant to any
provisions of:

               (i)  the Articles of Incorporation, By-laws or
     similar governing documents of Interstate or any of the
     Interstate Subsidiaries or Interstate Joint Ventures;

              (ii)  subject to obtaining the Interstate Required
     Statutory Approvals and the receipt of the Interstate

     to Interstate or any of the Interstate Subsidiaries or
     Interstate Joint Ventures or any of their respective
     properties or assets; or

             (iii)  subject to obtaining the third-party consents
     set forth in Section 6.4(b) of the Interstate Disclosure
     Schedule (the "Interstate Required Consents"), any material
     note, bond, mortgage, indenture, deed of trust, license,
     franchise, permit, concession, contract, lease or other
     instrument, obligation or agreement of any kind to which
     Interstate or any of the Interstate Subsidiaries or the
     Interstate Joint Ventures is a party or by which it or any
     of its properties or assets may be bound or affected,

excluding from the foregoing clauses (ii) and (iii) such
violations which, in the aggregate do not, and insofar as
reasonably can be foreseen, would not, have an Interstate
Material Adverse Effect.

          (c)  Statutory Approvals.  No declaration, filing or
registration with, or notice to or authorization, consent or
approval of, any Governmental Authority is necessary for the
execution and delivery of this Agreement or the Interstate/WPL
and Interstate/IES Stock Option Agreements by Interstate or the
consummation by Interstate of the transactions contemplated
hereby or thereby, except as described in Section 6.4(c) of the
Interstate Disclosure Schedule (the "Interstate Required
Statutory Approvals", it being understood that references in this
Agreement to "obtaining" such Interstate Required Statutory
Approvals shall mean making such declarations, filings or
registrations; giving such notices; obtaining such
authorizations, consents or approvals; and having such waiting
periods expire as are necessary to avoid a violation of law).

          (d)  Compliance. 

               (i)  Except as set forth in Section 6.4(d),
     Section 6.10 or Section 6.11 of the Interstate Disclosure
     Schedule, or as disclosed in the Interstate SEC Reports (as
     hereinafter defined) filed prior to the date hereof, neither
     Interstate nor any of the Interstate Subsidiaries nor, to
     the knowledge of Interstate, any Interstate Joint Venture is
     in violation of, is under investigation with respect to any
     violation of, or has been given notice or been charged with
     any violation of, any law, statute, order, rule, regulation,
     ordinance or judgment (including, without limitation, any
     applicable environmental law, ordinance or regulation) of
     any Governmental Authority, except for violations which, in
     the aggregate do not, and insofar as reasonably can be
     foreseen, would not, have an Interstate Material Adverse
     Effect.

     Joint Ventures have all Permits necessary to conduct their
     businesses as presently conducted, except those the failure

     reasonably can be foreseen, would not, have an Interstate
     Material Adverse Effect. 

             (iii)  Except as set forth in Section 6.4(d) of the
     Interstate Disclosure Schedule, each of Interstate and the
     Interstate Subsidiaries and Interstate Joint Ventures is not
     in breach, violation or default in the performance or
     observance of any term or provision of, and no event has
     occurred which, with lapse of time or action by a third
     party, could result in a default under, 

                    (A) its Articles of Incorporation or By-laws,
          or

                    (B) any contract, commitment, agreement,
          indenture, mortgage, loan agreement, note, lease, bond,
          license, approval or other instrument to which it is a
          party or by which it is bound or to which any of its
          property is subject, except for breaches, violations or
          defaults which, in the aggregate do not, and insofar as
          can be reasonably foreseen, would not, have an
          Interstate Material Adverse Effect.

          Section 6.5  Reports and Financial Statements.  

          (a)  The filings required to be made by Interstate and
the Interstate Subsidiaries since January 1, 1992 under the
Securities Act, the Exchange Act, the Power Act, and applicable
state laws and regulations have been filed with the SEC, the

applicable requirements of the appropriate statute and the rules
and regulations thereunder.  

          (b)  Interstate has made available to WPL and IES a

Interstate with the SEC since January 1, 1992 (as such documents
have since the time of their filing been amended or supplemented,
the "Interstate SEC Reports") and each other filing described in
Section 6.5(a).  As of their respective dates, the Interstate SEC
Reports did not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

          (c)  The audited consolidated financial statements and
unaudited interim financial statements of Interstate included in
the Interstate SEC Reports (collectively, the "Interstate

Form 10-Q under the Exchange Act) and fairly present in all
material respects the financial position of Interstate as of the
dates thereof and the results of its operations and cash flows

interim financial statements, to normal, recurring audit
adjustments.

respective businesses consistent with past practice and there has
not been, and no facts or conditions exist (other than facts or
conditions of general applicability to electric utility companies

would have, an Interstate Material Adverse Effect.

     or orders of any court, governmental department, commission,
     agency, instrumentality or authority or any arbitrator

     Interstate Joint Ventures,

which, when taken together with any other nondisclosures of
matters described in clauses (a), (b) and (c), have, or insofar
as reasonably can be foreseen, would have, an Interstate Material
Adverse Effect.

          Section 6.8  Registration Statement and Proxy
Statement.  

          (a)  None of the information supplied or to be supplied
by or on behalf of Interstate for inclusion or incorporation by
reference in

               (i)  the Registration Statement will, at the time

audits or other administrative proceedings or court proceedings
are presently pending with regard to any Taxes or Tax Returns of
Interstate or any of the Interstate Subsidiaries.

          (j)  Powers of Attorney.  No power of attorney
currently in force has been granted by Interstate or any of the
Interstate Subsidiaries concerning any Tax matter.

          (k)  Tax Rulings.  Neither Interstate nor any of the

the six years ended December 31, 1994 of (i) all Tax Returns, and
any amendments thereto, filed by Interstate or any of the
Interstate Subsidiaries, (ii) all audit reports received from any
taxing authority relating to any Tax Return filed by Interstate
or any of the Interstate Subsidiaries, and (iii) any Closing

          (n)  Code Section 280G.  Neither Interstate nor any of

transactions contemplated hereunder, separately or in the
aggregate, in the payment of any "excess parachute payments"
within the meaning of Section 280G of the Code.

          (o)  Liability for Others.  None of Interstate or any
of the Interstate Subsidiaries has any liability for Taxes of any
person other than Interstate and the Interstate Subsidiaries
(i) under Treasury Regulations Section 1.1502-6 (or any similar
provision of state, local or foreign law) as a transferee or
successor, (ii) by contract, or (iii) otherwise.

          Section 6.10  Employee Matters; ERISA.  

          (a)  Benefit Plans.  Section 6.10(a) of the Interstate
Disclosure Schedule contains a true and complete list of each
employee benefit plan, program or arrangement covering employees,
former employees or directors of Interstate and each of the
Interstate Subsidiaries or their beneficiaries, or providing
benefits to such persons in respect of services provided to any
such entity, including, but not limited to, employee benefit
plans within the meaning of Section 3(3) of ERISA and any
severance or change in control agreement (collectively, the
"Interstate Benefit Plans").  For the purposes of this
Section 6.10 only, the term "Interstate" shall be deemed to
include the predecessors of such company.

          (b)  Contributions.  Except as set forth in Section
6.10(b) of the Interstate Disclosure Schedule, all material
contributions and other payments required to be made by
Interstate or any of the Interstate Subsidiaries to any
Interstate Benefit Plan (or to any person pursuant to the terms
thereof) have been made or the amount of such payment or
contribution obligation has been reflected in the Interstate
Financial Statements.

          (c)  Qualification; Compliance.  Except as set forth in
Section 6.10(b) of the Interstate Disclosure Schedule, each of
the Interstate Benefit Plans intended to be "qualified" within
the meaning of Section 401(a) of the Code has been determined by
the IRS to be so qualified, and, to the knowledge of Interstate,
no circumstances exist that are reasonably expected by Interstate
to result in the revocation of any such determination. 
Interstate is in compliance in all respects with, and each of the
Interstate Benefit Plans is and has been operated in all respects
in compliance with, all applicable laws, rules and regulations
governing each such plan, including, without limitation, ERISA
and the Code except for any violations that, in the aggregate do
not, and insofar as reasonably can be foreseen, would not, give
rise to an Interstate Material Adverse Effect.  Each Interstate
Benefit Plan intended to provide for the deferral of income, the
reduction of salary or other compensation, or to afford other
income tax benefits, complies in all material respects with the
requirements of the applicable provisions of the Code or other
laws, rules and regulations required to provide such income tax
benefits.

          (d)  Liabilities.  With respect to the Interstate
Benefit Plans, individually and in the aggregate, no event has
occurred, and, to the knowledge of Interstate, there does not now
exist any condition or set of circumstances that could subject
Interstate or any of the Interstate Subsidiaries to any liability
arising under the Code, ERISA or any other applicable law
(including, without limitation, any liability of any kind
whatsoever, whether direct or indirect, contingent, inchoate or
otherwise to any such plan or the PBGC), or under any indemnity
agreement to which Interstate is subject, which liability,
excluding liability for PBGC premiums, benefit claims and funding
obligations payable in the ordinary course, has, or insofar as
reasonably can be foreseen, would have, an Interstate Material
Adverse Effect.

          (e)  Welfare Plans.  Except as set forth in Section
6.10(e) of the Interstate Disclosure Schedule, none of the
Interstate Benefit Plans that are "welfare plans" within the
meaning of Section 3(1) of ERISA provides for any benefits
payable to or on behalf of any employee or director after
termination of employment or service, as the case may be, other
than elective continuation coverage required to be provided under
Section 4980B of the Code or Part 6 of Title I of ERISA or
coverage which expires at the end of the calendar month following
such event.

          (f)  Documents made Available.  Interstate has made
available to WPL and IES a true and correct copy of each
collective bargaining agreement to which Interstate or any of the
Interstate Subsidiaries is a party or under which Interstate or
any of the Interstate Subsidiaries has obligations and, with
respect to each Interstate Benefit Plan, where applicable,

               (i) such plan and summary plan description,

               (ii) the most recent annual report filed with the
     IRS,

               (iii) each related trust agreement, insurance
     contract, service provider or investment management
     agreement (including all amendments to each such document),

               (iv) the most recent determination of the IRS with
     respect to the qualified status of such Interstate Benefit
     Plan, and

               (v) the most recent actuarial report or valuation.

          (g)  Payments Resulting from Merger.  Except as set
forth in Section 6.10(g) of the Interstate Disclosure Schedule:

               (i)  The consummation or announcement of any
     transaction contemplated by this Agreement will not (either
     alone or upon the occurrence of any additional or further
     acts or events) result in any

                    (A) payment (whether of severance pay or
          otherwise) becoming due from Interstate or any of the
          Interstate Subsidiaries to any officer, employee,
          former employee or director thereof or to the trustee
          under any "rabbi trust" or similar arrangement that
          would not have been paid without regard to such
          consummation or announcement, or

                    (B) benefit under any Interstate Benefit Plan
          being established or becoming accelerated, vested or
          payable; and

              (ii)  neither Interstate nor any of the Interstate
     Subsidiaries is a party to

                    (A) any management, employment, deferred
          compensation, severance (including any payment, right
          or benefit resulting from a change in control), bonus
          or other contract for personal services with any
          officer, director or employee,

                    (B) any consulting contract with any person
          who prior to entering into such contract was a director
          or officer of Interstate, or

                    (C) any material plan, agreement, arrangement
          or understanding similar to any of the foregoing.

          (h)  Labor Agreements.  Except as set forth in Section
6.10(h) of the Interstate Disclosure Schedule, as of the date
hereof, neither Interstate nor any of the Interstate Subsidiaries
is a party to any collective bargaining agreement or other labor
agreement with any union or labor organization.  To the knowledge
of Interstate, as of the date hereof, there is no current union
representation question involving employees of Interstate or any
of the Interstate Subsidiaries, nor does Interstate know of any
activity or proceeding of any labor organization (or
representative thereof) or employee group to organize any such
employees.  Except as disclosed in the Interstate SEC Reports
filed prior to the date hereof or in Section 6.10(h) of the
Interstate Disclosure Schedule,

               (i) there is no material unfair labor practice,
     employment discrimination or other complaint against
     Interstate or any of the Interstate Subsidiaries pending, or
     to the knowledge of Interstate, threatened, 

               (ii) there is no strike, lockout or material
     dispute, slowdown or work stoppage pending, or to the
     knowledge of Interstate threatened, against or involving
     Interstate or any of the Interstate Subsidiaries, and

               (iii) there is no material proceeding, claim,
     suit, action or governmental investigation pending or, to
     the knowledge of Interstate, threatened, in respect of which
     any director, officer, employee or agent of Interstate or
     any of the Interstate Subsidiaries is or may be entitled to
     claim indemnification from Interstate or such Interstate
     Subsidiary pursuant to their respective Articles of
     Incorporation or by-laws.

          Section 6.11  Environmental Protection.  Except as set
forth in Section 6.11 of the Interstate Disclosure Schedule or in
the Interstate SEC Reports filed prior to the date hereof:

          (a)  Compliance.  

               (i)  Each of Interstate and the Interstate
     Subsidiaries and Interstate Joint Ventures is in compliance
     with all applicable Environmental Laws, except where the
     failure to be in compliance, in the aggregate does not, and
     insofar as reasonably can be foreseen, would not, have an
     Interstate Material Adverse Effect; and 

              (ii)  neither Interstate nor any of the Interstate
     Subsidiaries and Interstate Joint Ventures has received any
     communication (written or oral) from any person or
     Governmental Authority that alleges that Interstate or any
     of the Interstate Subsidiaries and Interstate Joint Ventures
     is not in compliance, as required by clause (i) above, with
     applicable Environmental Laws.

          (b)  Environmental Permits.  Each of Interstate and the
Interstate Subsidiaries has obtained all Environmental Permits
necessary for the construction of their facilities and the
conduct of their operations, as applicable, and all such
Environmental Permits are in good standing or, where applicable,
a renewal application has been timely filed and is pending agency
approval, and Interstate and the Interstate Subsidiaries are in
compliance with all terms and conditions of the Environmental
Permits, except where the failure to be in such compliance, in
the aggregate does not, and insofar as reasonably can be
foreseen, would not, have an Interstate Material Adverse Effect.

          (c)  Environmental Claims.  There is no material
Environmental Claim pending

               (i) against Interstate or any of the Interstate
     Subsidiaries or Interstate Joint Ventures,

               (ii) against any person or entity whose liability
     for any Environmental Claim Interstate or any of the
     Interstate Subsidiaries has or may have retained or assumed
     either contractually or by operation of law, or

               (iii) against any real or personal property or
     operations which Interstate or any of the Interstate
     Subsidiaries owns, leases or manages, in whole or in part.

          (d)  Releases.  To the knowledge of Interstate, there
has not been any material Releases of any Hazardous Material that
would be reasonably likely to form the basis of any material
Environmental Claim against Interstate or any of the Interstate
Subsidiaries, or against any person or entity whose liability for
any material Environmental Claim Interstate or any of the
Interstate Subsidiaries has or may have retained or assumed
either contractually or by operation of law.

          (e)  Predecessors.  To the knowledge of Interstate,
with respect to any predecessor of Interstate or any of the
Interstate Subsidiaries, there is no material Environmental Claim
pending or threatened, and there has been no Release of Hazardous
Materials that would be reasonably likely to form the basis of
any material Environmental Claim.

          (f)  Disclosure.  To Interstate's knowledge, Interstate
has disclosed to each of WPL and IES all material facts which
Interstate reasonably believes form the basis of a material
Environmental Claim arising from

               (i) the cost of Interstate pollution control
     equipment currently required or known to be required in the
     future;

               (ii) current Interstate remediation costs or
     Interstate remediation costs known to be required in the
     future; or

               (iii) any other environmental matter affecting
     Interstate or the Interstate Subsidiaries or Interstate
     Joint Ventures.

          Section 6.12  Regulation as a Utility.  Interstate is
regulated as a public utility in the States of Iowa, Illinois and
Minnesota and in no other state.  Except as set forth in
Section 6.12 of the Interstate Disclosure Schedule, no
"subsidiary company" or "affiliate" of Interstate is subject to
regulation as a public utility or public service company (or
similar designation) by any other state in the United States or
any foreign country.

          Section 6.13  Vote Required.  The approval by the
holders of a majority of the outstanding shares of Interstate

the Interstate Merger is the only vote of the holders of any
class or series of capital stock of Interstate required for any
of the transactions required by this Agreement or the Stock

          Section 6.14  Accounting Matters.  Neither Interstate
nor, to Interstate's knowledge, any of its Affiliates has taken
or agreed to take any action that would prevent Interstate from
accounting for the transactions to be effected pursuant to this
Agreement as a pooling of interests in accordance with GAAP and
applicable SEC regulations.  

          Section 6.15  Applicability of Certain Delaware Law,
Etc.  Assuming the representations and warranties of WPL and IES
made in Sections 4.18 and 5.18, respectively, are correct, none
of the provisions of Section 203 of the DGCL, or any other
takeover related provisions of the DGCL (or to the knowledge of
Interstate, any other similar State statute) or the Restated
Articles of Incorporation or By-laws of Interstate are applicable
to the transactions contemplated by this Agreement, including the
granting or exercise of the Interstate/WPL and Interstate/IES
Stock Option Agreements (except as set forth in Section 6.15 of
the Interstate Disclosure Schedule. 

          Section 6.16  Opinion of Financial Advisor.  Interstate
has received the opinion of Salomon Brothers Inc ("Salomon")
dated November 10, 1995, to the effect that, as of the date
thereof, the consideration to be received by the holders of
Interstate Common Stock in the Interstate Merger is fair from a
financial point of view to the holders of Interstate Common
Stock.

          Section 6.17  Insurance.  Except as set forth in
Section 6.17 of the Interstate Disclosure Schedule, each of
Interstate and the Interstate Subsidiaries is, and has been
continuously since January 1, 1990, insured with financially
responsible insurers in such amounts and against such risks and
losses as are customary in all material respects for companies
conducting the business conducted by Interstate and the
Interstate Subsidiaries during such time period.  Except as set
forth in Section 6.17 of the Interstate Disclosure Schedule,
neither Interstate nor any of the Interstate Subsidiaries has
received any notice of cancellation or termination with respect
to any material insurance policy of Interstate or any of the
Interstate Subsidiaries.  The insurance policies of Interstate
and each of the Interstate Subsidiaries are valid and enforceable
policies in all material respects.

          Section 6.18  Ownership of WPL and IES Common Stock. 
Except pursuant to the terms of the WPL/Interstate and
IES/Interstate Stock Option Agreements, Interstate does not
"beneficially own" (as such term is defined for purposes of
Section 13(d) of the Exchange Act) any shares of WPL Common Stock
or IES Common Stock.

     equal to the product of

               (i) a fraction,

          of days between the payment date with respect to the
          most recent regular dividend paid by WPL, IES, or
          Interstate, as the case may be, and the Effective Time,
          and

                    (B)  the denominator of which equals 91, and

               (ii) the amount of the regular cash dividend most
     recently paid by WPL, IES or Interstate, as the case may be;

provided, however, that if any one or more of WPL, IES or
Interstate has declared a regular quarterly dividend on shares of
its Common Stock with a payment date (the "Payment Date") after
the Effective Time, then no dividend as provided for in this
Section 7.3(b) shall be declared or paid with respect to such
shares and the dividend of the other party or parties shall be
calculated by substituting "Payment Date" for "Effective Time" in
clause (i)(A) of this Section 7.3(b).

               (i) WPL may redeem all or any portion of the WP&LC

employees, accountants, counsel, investment bankers, financial
advisors and other representatives of the other parties
(collectively, "Representatives") reasonable access, during
normal business hours throughout the period prior to the
Effective Time, to all of its properties, books, contracts,
commitments and records (including, but not limited to, Tax

cause its Subsidiaries to, furnish promptly to the other parties 

               (i)  access to each report, schedule and other
     document filed or received by it or any of its Subsidiaries

     Agreement or for any other reason related to the
     transactions contemplated by this Agreement.  

               (b)  Each party shall, and shall cause its

representation, covenant or agreement is made by any party hereto
with respect to information supplied by any other party for
inclusion in the Joint Proxy/Registration Statement.

          (b)  Letter of WPL's Accountants.  WPL shall use best
efforts to cause to be delivered to IES and Interstate a letter
of Arthur Andersen LLP, dated a date within two business days
before the date of the Joint Proxy/Registration Statement, and
addressed to IES and Interstate, in form and substance reasonably
satisfactory to IES and Interstate, and customary in scope and

efforts to cause to be delivered to WPL and Interstate a letter

satisfactory to WPL and Interstate and customary in scope and
substance for "cold comfort" letters delivered by independent
public accountants in connection with registration statements on
Form S-4.

          (d)  Letter of Interstate's Accountants.  Interstate
shall use best efforts to cause to be delivered to WPL and IES a
letter of Deloitte & Touche LLP, dated a date within two business
days before the date of the Joint Proxy/Registration Statement,

satisfactory to WPL and IES and customary in scope and substance
for "cold comfort" letters delivered by independent public
accountants in connection with registration statements on
Form S-4.

          (e)  Fairness Opinions.  It shall be a condition to the
mailing of the Joint Proxy/Registration Statement to the
shareholders of WPL, IES and Interstate that 

               (i)  WPL shall have received an opinion from
     Merrill, dated the date of the Joint Proxy/Registration
     Statement, to the effect that, as of the date thereof, the
     IES Ratio and the Interstate Ratio are fair to WPL from a
     financial point of view, 

              (ii)  IES shall have received an opinion from
     Morgan, dated the date of the Joint Proxy/Registration
     Statement, to the effect that, as of the date thereof, the
     IES Ratio, taking into account the Interstate Ratio, is fair
     from a financial point of view to the holders of IES Common
     Stock, and 

             (iii)  Interstate shall have received an opinion
     from Salomon, dated the date of the Joint Proxy/Registration
     Statement, to the effect that, as of the date thereof, the
     consideration to be received by the holders of Interstate
     Common Stock in the Interstate Merger is fair from a
     financial point of view to the holders of Interstate Common
     Stock.

          Section 8.3  Regulatory Matters.

          (a)  HSR Filings.  Each party hereto shall file or
cause to be filed with the Federal Trade Commission and the

          Section 8.5  Director and Officer Indemnification.

          (a)  Indemnification.  To the extent, if any, not
provided by an existing right of indemnification or other
agreement or policy, from and after the Effective Time, the
Company shall, to the fullest extent permitted by applicable law,
indemnify, defend and hold harmless each person who is now, or
has been at any time prior to the date hereof, or who becomes
prior to the Effective Time, an officer, director or employee of
any of the parties hereto or any Subsidiary (each an "Indemnified
Party" and collectively, the "Indemnified Parties") against 

               (i)  all losses, expenses (including reasonable
     attorney's fees and expenses), claims, damages or
     liabilities or, subject to the proviso of the next
     succeeding sentence, amounts paid in settlement, arising out
     of actions or omissions occurring at or prior to the
     Effective Time (and whether asserted or claimed prior to, at
     or after the Effective Time) that are, in whole or in part,
     based on or arising out of the fact that such person is or
     was a director, officer or employee of such party (the
     "Indemnified Liabilities"), and

              (ii)  all Indemnified Liabilities to the extent
     that they are based on or arise out of or pertain to the
     transactions contemplated by this Agreement.

In the event of any such loss, expense, claim, damage or
liability (whether or not arising before the Effective Time), 

                    (A) the Company shall pay the reasonable fees
          and expenses of counsel selected by the Indemnified
          Parties, which counsel shall be reasonably satisfactory
          to the Company, promptly after statements therefor are
          received and otherwise advance to such Indemnified
          Party upon request reimbursement of documented expenses
          reasonably incurred, 

                    (B)  the Company will cooperate in the
          defense of any such matter, and

                    (C)  any determination required to be made
          with respect to whether an Indemnified Party's conduct
          complies with the standards set forth under Sections
          180.0850 through 180.0859 of the WBCL and the Restated
          Articles of Incorporation or By-laws of the Company (as
          the same shall be amended from time to time) shall be
          made by independent counsel mutually acceptable to the
          Company and the Indemnified Party; provided, however,
          that the Company shall not be liable for any settlement
          effected without its written consent (which consent
          shall not be unreasonably withheld).  

          The Indemnified Parties as a group may retain only one
law firm with respect to each related matter except to the extent
that there is, in the opinion of counsel to an Indemnified Party,
under applicable standards of professional conduct, a conflict on
any significant issue between positions of such Indemnified Party
and any other Indemnified Party or Indemnified Parties.

          (b)  Insurance.  For a period of six years after the
Effective Time, the Company shall cause to be maintained in
effect policies of directors' and officers' liability insurance
maintained by WPL, IES and Interstate for the benefit of those
persons who are currently covered by such policies on terms no
less favorable than the terms of such current insurance coverage;
provided, however, that the Company shall not be required to
expend in any year an amount in excess of 150% of the annual
aggregate premiums currently paid by WPL, IES and Interstate for
such insurance; and provided, further, that if the annual
premiums of such insurance coverage exceed such amount, the
Company shall be obligated to obtain a policy with the best
coverage available, in the reasonable judgment of the Board of
Directors of the Company, for a cost not exceeding such amount.

          (c)  Successors.  In the event the Company or any of
its successors or assigns (i) consolidates with or merges into
any other person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger, or
(ii) transfers all or substantially all of its properties and
assets to any person, then and in either such case, proper
provisions shall be made so that the successors and assigns of
the Company shall assume the obligations set forth in this
Section 8.5.

          (d)  Survival of Indemnification.  To the fullest
extent permitted by law, from and after the Effective Time, all
rights to indemnification as of the date hereof in favor of the
employees, agents, directors and officers of WPL, IES and
Interstate and their respective Subsidiaries with respect to
their activities as such prior to the Effective Time, as provided
in their respective articles of incorporation and by-laws in
effect on the date thereof, or otherwise in effect on the date
hereof, shall survive the Merger and shall continue in full force
and effect for a period of not less than six years from the
Effective Time.

          (e)  Benefit.  The provisions of this Section 8.5 are
intended to be for the benefit of, and shall be enforceable by,
each Indemnified Party, his or her heirs and his or her
representatives.

          Section 8.6  Disclosure Schedules.  On the date hereof,

          (a)  IES has delivered to WPL and Interstate an IES
Disclosure Schedule, accompanied by a certificate signed by the
chief financial officer of IES stating the IES Disclosure
Schedule is being delivered pursuant to this Section 8.6(a), 

          (b)  WPL has delivered to IES and Interstate a WPL

Interstate Disclosure Schedule, accompanied by a certificate
signed by the principal financial officer of Interstate stating

this Section 8.6(c).  

          (d)  The WPL Disclosure Schedule, the IES Disclosure
Schedule and the Interstate Disclosure Schedule are collectively
referred to herein as the "Disclosure Schedules."  

          (e)  The Disclosure Schedules constitute an integral
part of this Agreement and modify the respective representations,
warranties, covenants or agreements of the parties hereto
contained herein to the extent that such representations,
warranties, covenants or agreements expressly refer to the
Disclosure Schedules.  Anything to the contrary contained herein
or in the Disclosure Schedules notwithstanding, any and all
statements, representations, warranties or disclosures set forth
in the Disclosure Schedules shall be deemed to have been made on
and as of the date hereof.

          Section 8.7  Public Announcements.  Subject to each
party's disclosure obligations imposed by law, WPL, IES and
Interstate will cooperate with each other in the development and
distribution of all news releases and other public information
disclosures with respect to this Agreement or any of the
transactions contemplated hereby and shall not issue any public
announcement or statement with respect hereto or thereto without
the consent of the other parties (which consent shall not be
unreasonably withheld).  

          Section 8.8  Rule 145 Affiliates.  Within 30 days
before the Closing Date, WPL shall identify in a letter to IES
and Interstate, IES shall identify in a letter to WPL and
Interstate, and Interstate shall identify in a letter to WPL and
IES, all persons who are, and to such person's knowledge who will
be at the Closing Date, "affiliates" of WPL, IES and Interstate,
respectively, as such term is used in Rule 145 under the
Securities Act (or otherwise under applicable SEC accounting
releases with respect to pooling-of-interests accounting
treatment).  Each of WPL, IES and Interstate shall use all
reasonable efforts to cause their respective affiliates
(including any person who may be deemed to have become an
affiliate after the date of the letter referred to in the prior
sentence) to deliver to the Company on or prior to the Closing
Date a written agreement substantially in the form attached as
Exhibit 8.8(a) with respect to affiliates of WPL and Exhibit
8.8(b) with respect to affiliates of IES and Interstate (each, an
"Affiliate Agreement").

          Section 8.9  Employee Agreements and Workforce Matters.

          (a)  Certain Employee Agreements.  Subject to Section
8.10, Section 8.14 and Section 8.15, the Company and its
Subsidiaries shall honor, without modification, all contracts,
agreements, collective bargaining agreements and commitments of
the parties prior to the date hereof which apply to any current
or former employee or current or former director of the parties
hereto; provided, however, that this undertaking is not intended
to prevent the Company from enforcing such contracts, agreements,
collective bargaining agreements and commitments in accordance
with their terms, including, without limitation, any reserved
right to amend, modify, suspend, revoke or terminate any such
contract, agreement, collective bargaining agreement or
commitment.

          (b)  Workforce Matters.  

               (i)  Subject to applicable collective bargaining
     agreements, for a period of three years following the
     Effective Time, any reductions in workforce in respect to
     employees of the Company (except as provided in subparagraph
     (ii) below) shall be made on a fair and equitable basis, in
     light of the circumstances and the objectives to be
     achieved, giving consideration to previous work history, job
     experience and qualifications, without regard to whether
     employment was with WPL or its Subsidiaries, IES or its
     Subsidiaries, or Interstate or its Subsidiaries, and any
     employees whose employment is terminated or jobs are
     eliminated by the Company or any of its Subsidiaries during
     such period shall be entitled to participate on a fair and
     equitable basis in the job opportunity and employment
     placement programs offered by the Company or any of its
     Subsidiaries.  Any workforce reductions carried out
     following the Effective Time by the Company and its
     Subsidiaries shall be done in accordance with all applicable
     collective bargaining agreements, and all laws and
     regulations governing the employment relationship and
     termination thereof including, without limitation, the
     Worker Adjustment and Retraining Notification Act and
     regulations promulgated thereunder, and any comparable state
     or local law.

          (ii)  During the three-year period ending on the third
     anniversary of the Closing Date, the overall employment
     levels of the Company in the greater Dubuque area as
     measured against such levels as of the Closing Date will not
     fall (for any reason whatsoever, including attrition of all
     types) below the following levels, 

                    (A)  prior to the first anniversary of the
          Closing Date, 90%, 

                    (B)  prior to the second anniversary of the
          Closing Date, 75%, and 

                    (C)  prior to the third anniversary of the
          Closing Date, 60%.

          Section 8.10  Employee Benefit Plans.  Subject to
Section 7.10, each of the WPL Benefit Plans, the IES Benefit
Plans and the Interstate Benefit Plans in effect at the date
hereof shall be maintained in effect with respect to the
employees or former employees of WPL and any of its Subsidiaries,
IES and any of its Subsidiaries, and Interstate and any of its
Subsidiaries, respectively, who are covered by any such Benefit
Plan immediately prior to the Closing Date (the "Affiliated
Employees") until the Company otherwise determines after the
Effective Time; provided, however, that nothing herein contained
shall limit any reserved right contained in any such WPL Benefit
Plan, IES Benefit Plan or Interstate Benefit Plan, to amend,
modify, suspend, revoke or terminate any such plan; provided,
further, however, that the Company or its Subsidiaries shall
provide to the Affiliated Employees for a period of not less than
one year following the Effective Time benefits, other than with
respect to plans referred to in Section 8.11, which are no less
favorable in the aggregate than those provided under the WPL
Benefit Plans, the IES Benefit Plans or the Interstate Benefit
Plans, as the case may be.  Without limitation of the foregoing,
each participant of any such WPL Benefit Plan, IES Benefit Plan
or Interstate Benefit Plan shall receive credit for purposes of
eligibility to participate, vesting, benefit accrual and
eligibility to receive benefits under a benefit plan of the
Company or any of its Subsidiaries or Affiliates for service
credited for the corresponding purpose under such benefit plan;
provided, however, that such crediting of service shall not
operate to duplicate any benefit to any such participant or the
funding for any such benefit.  Any person hired by the Company or
any of its Subsidiaries after the Closing Date who was not
employed by any party hereto or its Subsidiaries immediately
prior to the Closing Date shall be eligible to participate in
such benefit plans maintained, or contributed to, by the Company
or the Subsidiary, division or operation by which such person is
employed, provided that such person meets the eligibility
requirements of the applicable plan.

          Section 8.11  Stock Option and Other Stock Plans.

          (a)  Amendment of Stock Plans and Agreements.  Prior to
the Effective Time, IES shall amend its Stock Plan (as
hereinafter defined) and each underlying award agreement to
provide that (i) each outstanding option to purchase shares of
IES Common Stock (a "IES Stock Option"), along with any tandem
stock appreciation right, shall constitute an option to acquire
shares of WPL Common Stock, on the same terms and conditions as
were applicable under such IES Stock Option, based on the same
number of shares of WPL Common Stock as the holder of such IES
Stock Option would have been entitled to receive pursuant to the
Merger in accordance with Article II had such holder exercised
such option in full immediately prior to the Effective Time;
provided, however, that the number of shares, the option price,
and the terms and conditions of exercise of such option, shall be
determined in a manner that preserves both (A) the aggregate gain
(or loss) on the IES Stock Option immediately prior to the
Effective Time and (B) the ratio of the exercise price per share
of the IES Stock to the fair market value (determined immediately
prior to Effective Time) per share subject to such option; and
provided, further, that in the case of any option to which
Section 421 of the Code applies by reason of its qualification
under any of Sections 422-424 of the Code, the option price, the
number of shares purchasable pursuant to such option and the
terms and conditions of exercise of such option shall be
determined in order to comply with Section 424(a) of the Code;
and (ii) each other outstanding award under the IES Stock Plan
(the "IES Stock Awards") shall constitute an award based upon the
same number of shares of WPL Common Stock as the holder of such
IES Stock Award would have been entitled to receive pursuant to
the Merger in accordance with Article II had such holder been the
absolute owner, immediately before the Effective Time, of the
shares of IES Common Stock on which such IES Stock Award is
based, and otherwise on the same terms and conditions as governed
by such IES Stock Award immediately before the Effective Time. 
At the Effective Time, the Company shall assume each stock award
agreement relating to the IES Stock Plan, as amended as
previously provided.  As soon as practicable after the Effective
Time, the Company shall deliver to the holders of IES Stock
Options and IES Stock Awards appropriate notices setting forth
such holders' rights with respect to such options and awards
after the Effective Time and each underlying stock award
agreement, each as assumed by the Company.

          (b)  Company Action.  After the Effective Time, with
respect to the IES Stock Plan, and any other plans under which
the delivery of WPL Common Stock is required upon payment of
benefits, grant of awards or exercise of options (the "Stock
Plans"), the Company shall take all corporate action necessary or
appropriate to

               (i)  obtain shareholder approval with respect to
     such Stock Plan to the extent such approval is required for
     purposes of the Code or other applicable law, or to enable
     such Stock Plan to comply with Rule 16b-3 promulgated under
     the Exchange Act,

              (ii)  reserve for issuance under such plan or
     otherwise provide a sufficient number of shares of WPL
     Common Stock for delivery upon payment of benefits, grant of
     awards or exercise of options under such Stock Plan, and

             (iii)  as soon as practicable after the Effective
     Time, file registration statements on Form S-3 or Form S-8,
     as the case may be (or any successor or other appropriate
     forms), with respect to the shares of WPL Common Stock
     subject to such Stock Plan to the extent such registration
     statement is required under applicable law, and the Company
     shall use its best efforts to maintain the effectiveness of
     such registration statements (and maintain the current
     status of the prospectuses contained therein) for so long as
     such benefits and grants remain payable and such options
     remain outstanding. 

With respect to those individuals who subsequent to the Merger
will be subject to the reporting requirements under
Section 16(a) of the Exchange Act, the Company shall administer
the Stock Plans, where applicable, in a manner that complies with
Rule 16b-3 promulgated under the Exchange Act.

          Section 8.12  No Solicitations.  

          (a)  No party hereto shall, and each such party shall
use its best efforts to cause its Subsidiaries not to, permit any
of its Representatives, directly or indirectly initiate, solicit
or encourage, or take any action to facilitate the making of any
offer or proposal which constitutes or is reasonably likely to
lead to, any Business Combination Proposal (as hereinafter
defined), or, in the event of an unsolicited Business Combination
Proposal, except to the extent required by their fiduciary duties
under applicable law if so advised in a written opinion of
outside counsel, engage in negotiations or provide any
information or data to any person relating to any Business
Combination Proposal.

          (b)  Each party hereto shall notify the other parties
orally and in writing of any such inquiries, offers or proposals
(including, without limitation, the terms and conditions of any
such proposal and the identity of the person making it), within
24 hours of the receipt thereof, shall keep the other parties
informed of the status and details of any such inquiry, offer or
proposal, and shall give the other parties five days' advance
notice of any agreement to be entered into with or any
information to be supplied to any person making such inquiry,
offer or proposal.  Each party hereto shall immediately cease and
cause to be terminated all existing discussions and negotiations,
if any, with any parties conducted heretofore with respect to any
Business Combination Proposal.

          :\W  As used in this Section 8.12, "Business
Combination Proposal" shall mean any tender or exchange offer,
proposal for a merger, consolidation or other business
combination involving any party to this Agreement or any of its
material Subsidiaries, or any proposal or offer (in each case,
whether or not in writing and whether or not delivered to the
shareholders of a party generally) to acquire in any manner,
directly or indirectly, a substantial equity interest in or a
substantial portion of the assets of any party to this Agreement
or any of its material Subsidiaries, other than pursuant to the
transactions contemplated by this Agreement.

          (d)  Nothing contained herein shall prohibit a party
from taking and disclosing to its shareholders a position
contemplated by Rule 14e-2(a) under the Exchange Act with respect
to a Business Combination Proposal made by means of a tender
offer.

          Section 8.13  Company Board of Directors.

          (a)  WPL's, IES's and Interstate's respective Boards of
Directors will take such action as may be necessary to cause the
number of directors comprising the full Board of Directors of the
Company at the Effective Time to be fifteen (15) persons.  The
directors shall be divided into three classes (hereafter referred
to as "Class I," "Class II" and "Class III") of five directors
each.  Class I directors shall be appointed for a term expiring
at the first annual meeting of shareholders of the Company
following the Effective Time, Class II directors shall be
appointed for a term expiring at the second annual meeting of
shareholders of the Company following the Effective Time, and
Class III directors shall be appointed for a term expiring at the
third annual meeting of shareholders of the Company following the
Effective Time, and in each case until their respective
successors have been duly elected and qualified.  Of the
directors comprising Class I, two shall be designated by each of
IES and WPL and one shall be designated by Interstate prior to
the Effective Time.  Of the directors comprising Class II, two
shall be designated by each of IES and WPL, and one shall be
designated by Interstate prior to the Effective Time.  Class III
directors shall consist of Lee Liu ("Mr. Liu"), Mr. Davis and Mr.
Stoppelmoor as well as two additional directors, one director
designated by each of IES and WPL prior to the Effective Time. 
Directors designated by IES, WPL and Interstate (including their
successors) are hereinafter sometimes referred to as the "IES
Directors," "WPL Directors" and "Interstate Directors,"
respectively.  Notwithstanding the foregoing, if, prior to the
Effective Time, any of such designees shall decline or be unable
to serve, the respective party which designated such person shall
designate another person to serve in such person's stead.  In
addition, subject to the limitations set forth in Section
8.13(b), for a period commencing as of the Effective Time and
expiring on the date of the third annual meeting of shareholders
of the Company following the Effective Time, the IES, WPL and
Interstate Directors (each as a separate group) shall be entitled
to nominate those persons who will be eligible to be appointed,
elected or re-elected as IES, WPL and Interstate Directors,
respectively.  For purposes of this Agreement, Messrs. Liu, Davis
and Stoppelmoor shall be deemed to have been designated by IES,
WPL and Interstate, respectively.  WPL's, IES's and Interstate's
respective Boards of Directors will also take such action as may
be necessary to cause the Nominating, Audit and Compensation
Committees of the Board of Directors of the Company at the
Effective Time to consist proportionally (to the extent
reasonably practicable) of designees of each of WPL, IES and
Interstate.  

          (b)  For a period of five years following the Effective
Time, no person who is an executive officer or employee of the
Company or any of its Subsidiaries shall be eligible to serve as
a director of the Company, except for Messrs. Liu, Davis and
Stoppelmoor; provided, however, that if Mr. Davis is not then
serving as Chief Executive Officer of the Company, the individual
serving in such capacity shall be eligible to serve as a director
of the Company.

          (c)  Meetings of the Board of Directors of the Company
shall be reasonably rotated among the WPL, IES and Interstate
cities for so long as separate utility headquarters exist in
those cities.

Directors for at least the remainder of the five year term
specified above.  Subject to the five-year term specified above,
Mr. Davis shall be entitled to serve in all of the above-

of Executive Vice President and Chief Financial Officer of the
Company as of the Effective Time and shall be entitled to serve
in such capacities until his successor is duly elected or

Officer of the Nonregulated Company as of the Effective Time.

          (g)  Subject to Section 8.14(h), if any of the
foregoing persons is unable or unwilling to hold such offices for
the periods set forth above, his successor shall be selected by
the Board of Directors of the Company in accordance with its By-
laws.

          (h)  For a period of five years following the Effective
Time, a majority vote of the WPL Directors or the successors
thereto shall, in addition to any other vote required by law, be
required to appoint or elect any person other than Mr. Davis as
Chief Executive Officer of the Company.

          Section 8.15  Employment Contracts.  WPL shall, as of
or prior to the Effective Time, enter into employment contracts
with each of Messrs. Liu, Davis, Stoppelmoor, Chase and Fisher in
the forms set forth in Exhibit 8.15.1, 8.15.2, 8.15.3, 8.15.4 and

          Section 8.16  Post-Merger Operations.  Following the
Effective Time, the Company shall conduct its operations or take
such action in accordance with the following:

          (a)  the Company shall maintain its headquarters in
Madison, Wisconsin, but this location will be evaluated over time
as future business needs dictate.

          (b)  during the three-year period following the
Effective Time, Utilities, WP&LC, and Interstate shall maintain
their separate corporate existences and shall maintain their
headquarters in their present locations of Cedar Rapids, Iowa,
Madison, Wisconsin and Dubuque, Iowa, respectively;

          (c)  immediately following the Effective Time, the
Company shall cause the IES nonregulated holding company to merge
with and into the WPL nonregulated holding company, with the WPL
nonregulated holding company being the surviving corporation (the
combined company is herein referred to as the "Nonregulated
Company"); and

          (d)  during the five-year period following the
Effective Time or for such shorter period as the following
entities maintain their separate corporate existences, the
Company shall use its best efforts to insure that the composition
of the Board of Directors of each of Utilities, WP&LC and
Interstate and Nonregulated Company will be identical to the
composition of the Board of Directors of the Company.

          Section 8.17  Expenses.  Subject to Section 10.3, all
costs and expenses incurred in connection with this Agreement and
the transactions contemplated hereby shall be paid by the party
incurring such expenses, except that those expenses incurred in
connection with printing the Joint Proxy/Registration Statement,
as well as the filing fee relating thereto, shall be shared by
the parties in the following proportions: 43% by WPL, 14% by
Interstate and 43% by IES.

          Section 8.18  Further Assurances.  Each party will, and
will cause its Subsidiaries and, will use its best efforts to
cause its Joint Ventures to, execute such further documents and
instruments and take such further actions as may reasonably be
requested by the terms hereof.  The parties expressly acknowledge
and agree that, although it is their current intention to effect
a business combination among themselves in the form contemplated
by this Agreement, it may be preferable to effectuate such a
business combination by means of an alternative structure in
light of the conditions set forth in Section 9.1(e), Section
9.2(e), Section 9.2(f), Section 9.3(e), Section 9.3(f), Section
9.4(e) and Section 9.4(f).  Accordingly, if the only conditions
to the parties' obligations to consummate the Merger which are
not satisfied or waived are receipt of any one or more of the WPL
Required Consents, WPL Required Statutory Approvals, IES Required
Consents, IES Required Statutory Approvals, Interstate Required
Consents, Interstate Required Statutory Approvals or the opinions
referred to in Sections 9.2(e), 9.3(e), and 9.4(e), and the
adoption of an alternative structure (that otherwise
substantially preserves for WPL, IES and Interstate the economic
and other material benefits of the Merger) would result in such
conditions being satisfied or waived, then the parties shall use
their respective best efforts to effect a business combination
among themselves by means of a mutually agreed upon structure
other than the Merger that so preserves such benefits; provided
that, prior to closing any such restructured transaction, all
material third party and Governmental Authority declarations,
filings, registrations, notices, authorizations, consents or
approvals necessary to effect such alternative business
combination shall have been obtained and all other conditions to
the parties' obligations to consummate the Merger, as applied to
such alternative business combination, shall have been satisfied
or waived.

          Section 8.19  Charter and By-law Amendments.  Prior to
the Closing, WPL shall cause its Articles of Incorporation and
By-laws to be amended as contemplated in Section 8.19 of the WPL
Disclosure Schedule.

          Section 8.20  IES Rights Agreement.  Prior to or at the
time of the Closing, IES shall amend the IES Rights Agreement to
cause it to terminate effective as of the Effective Time.

of cases (i) and (ii) for such failures of representations or

     Lardner dated as of the Closing Date, to the effect that the
     Merger will be treated as a tax-free reorganization under
     Section 368(a) of the Code; and 

               (ii)  WPL and Foley & Lardner shall have had the
     opportunity to review the tax opinions of IES's and
     Interstate's special tax counsel, as set forth in Sections
     9.2(e)(i) and 9.3(e)(i), respectively, including the
     representations, covenants or other matters in reliance on
     which the opinions are being rendered, and shall be
     reasonably satisfied with the completeness and accuracy of
     said opinions.

          (f)  Required Consents.  The IES Required Consents and
the Interstate Required Consents, the failure of which to obtain
would have an IES Material Adverse Effect or an Interstate
Material Adverse Effect, shall have been obtained.

          (g)  Affiliate Agreements.  WPL shall have received
Affiliate Agreements, duly executed by each Affiliate of IES and
Interstate, substantially in the form of Exhibit 8.8(b), as

                TERMINATION, AMENDMENT AND WAIVER

          Section 10.1  Termination.  This Agreement may be
terminated at any time prior to the Closing Date, whether before
or after approval by the shareholders of the respective parties
hereto contemplated by this Agreement:

          (a)  by mutual written consent of WPL, IES and
Interstate;

          (b)  by any party hereto, by written notice to the
other parties, if the Effective Time shall not have occurred on
or before May 10, 1997 (the "Initial Termination Date");
provided, however, that the right to terminate the Agreement
under this Section 10.1(b) shall not be available to any party
whose failure to fulfill any obligation under this Agreement has
been the cause of, or resulted in, the failure of the Effective
Time to occur on or before the Initial Termination Date; and
provided, further, that if on the Initial Termination Date the
conditions to the Closing set forth in Sections 9.1(e), 9.2(f),
9.3(f) and/or 9.4(f) shall not have been fulfilled but all other
conditions to the Closing shall be fulfilled or shall be capable
of being fulfilled, then the Initial Termination Date shall be
extended to May 10, 1998;

          (c)  by any party hereto, by written notice to the
other parties, if 

               (i)  the WPL Shareholders' Approval shall not have
     been obtained at a duly held WPL Special Meeting, including
     any adjournments thereof, or 

              (ii)  the IES Shareholders' Approval shall not have
     been obtained at a duly held IES Special Meeting, including
     any adjournments thereof, or

             (iii)  the Interstate Shareholders' Approval shall
     not have been obtained at a duly held Interstate Special
     Meeting, including any adjournments thereof;

          (d)  by any party hereto, if any state or Federal law,
order, rule or regulation is adopted or issued, which has the
effect, as supported by the written opinion of outside counsel
for such party, of prohibiting the Merger (including either or
both the IES Merger and the Interstate Merger), or by any party
hereto if any court of competent jurisdiction in the United
States or any State shall have issued an order, judgment or
decree permanently restraining, enjoining or otherwise
prohibiting the Merger (including either or both the IES Merger
and the Interstate Merger), and such order, judgment or decree
shall have become final and nonappealable;

          (e)  by IES, upon two days' prior notice to WPL and
Interstate, if, as a result of a tender offer by a party other
than WPL or Interstate or any of their respective Affiliates or
any written offer or proposal with respect to a merger, sale of a
material portion of its assets or other business combination
(each, a "Business Combination") by a party other than WPL or
Interstate or any of their respective Affiliates, the Board of
Directors of IES determines in good faith that its fiduciary
obligations under applicable law require that such tender offer
or other written offer or proposal be accepted; provided,
however, that 

               (i) the Board of Directors of IES shall have been
     advised in a written opinion of outside counsel that
     notwithstanding a binding commitment to consummate an
     agreement of the nature of this Agreement entered into in
     the proper exercise of its applicable fiduciary duties, and
     notwithstanding all concessions which may be offered by WPL
     and Interstate in negotiations entered into pursuant to
     clause (ii) below, such fiduciary duties would require the
     directors to reconsider such commitment as a result of such
     tender offer or other written offer or proposal; and

               (ii) prior to any such termination, IES shall, and
     shall cause its respective financial and legal advisors to,
     negotiate with WPL and Interstate to make such adjustments
     in the terms and conditions of this Agreement as would
     enable IES to proceed with the transactions contemplated
     herein on such adjusted terms;

          (f)  by Interstate, upon two days' prior notice to WPL
and IES, if, as a result of a tender offer by a party other than
WPL or IES or any of their respective Affiliates or any written
offer or proposal with respect to a Business Combination by a
party other than WPL or IES or any of their respective
Affiliates, the Board of Directors of Interstate determines in
good faith that its fiduciary obligations under applicable law
require that such tender offer or other written offer or proposal
be accepted; provided, however, that

               (i) the Board of Directors of Interstate shall
     have been advised in a written opinion of outside counsel
     that notwithstanding a binding commitment to consummate an
     agreement of the nature of this Agreement entered into in
     the proper exercise of its applicable fiduciary duties, and
     notwithstanding all concessions which may be offered by WPL
     and IES in negotiations entered into pursuant to clause (ii)
     below, such fiduciary duties would require the directors to
     reconsider such commitment as a result of such tender offer
     or other written offer or proposal; and

               (ii) prior to any such termination, Interstate
     shall, and shall cause its respective financial and legal
     advisors to, negotiate with WPL and IES to make such
     adjustments in the terms and conditions of this Agreement as
     would enable Interstate to proceed with the transactions
     contemplated herein on such adjusted terms;

          (g)  by WPL, upon two days' prior notice to IES and
Interstate, if, as a result of a tender offer by a party other
than IES or Interstate or any of their respective Affiliates or
any written offer or proposal with respect to a Business
Combination by a party other than IES or Interstate or any of
their respective Affiliates, the Board of Directors of WPL
determines in good faith that its fiduciary obligations under
applicable law require that such tender offer or other written
offer or proposal be accepted; provided, however, that 

               (i) the Board of Directors of WPL shall have been
     advised in a written opinion of outside counsel that
     notwithstanding a binding commitment to consummate an
     agreement of the nature of this Agreement entered into in
     the proper exercise of its applicable fiduciary duties, and
     notwithstanding all concessions which may be offered by IES
     and Interstate in negotiations entered into pursuant to
     clause (ii) below, such fiduciary duties would require the
     directors to reconsider such commitment as a result of such
     tender offer or other written offer or proposal; and 

               (ii) prior to any such termination, WPL shall, and
     shall cause its respective financial and legal advisors to,
     negotiate with IES and Interstate to make such adjustments
     in the terms and conditions of this Agreement as would
     enable WPL to proceed with the transactions contemplated
     herein on such adjusted terms;

          (h)  by IES, by written notice to WPL and Interstate,
if

              (i)  there exists any breach or breaches of the
     representations and warranties of WPL or Interstate made
     herein or in any of the Stock Option Agreements pursuant to
     which either of them is a grantor of options, which
     breaches, individually or in the aggregate have or, insofar
     as reasonably can be foreseen, would have, a WPL Material
     Adverse Effect or an Interstate Material Adverse Effect, and
     such breaches shall not have been remedied within 20 days
     after receipt by WPL or Interstate, as the case may be, of
     notice in writing from IES, specifying the nature of such
     breaches and requesting that they be remedied;

             (ii)  WPL or Interstate (and/or its appropriate
     Subsidiaries) shall not have performed and complied with its
     agreements and covenants contained in Sections 7.3 and 7.4
     or shall have failed to perform and comply with, in all
     material respects, their other agreements and covenants
     hereunder or under the Stock Option Agreements and such
     failure to perform or comply shall not have been remedied
     within 20 days after receipt by WPL or Interstate, as the
     case may be, of notice in writing from IES, specifying the
     nature of such failure and requesting that it be remedied;
     or

             (iii)  the Board of Directors of WPL or Interstate
     or any committee thereof:

                    (A)  shall withdraw or modify in any manner
          adverse to IES its approval or recommendation of this
          Agreement, or the IES Merger or the Interstate Merger,

                    (B)  shall fail to reaffirm such approval or

                    (C)  shall approve or recommend any Business
          Combination involving WPL or Interstate other than the

          for shares of capital stock of WPL or Interstate, in
          each case, by or involving a party other than IES or
          any of its Affiliates or

                    (D)  shall resolve to take any of the actions
          specified in clause (A), (B) or (C); 

          (i)  by Interstate, by written notice to WPL and IES,
if

               (i)  there exists any breach or breaches of the
     representations and warranties of WPL or IES made herein or
     in any of the Stock Option Agreements pursuant to which
     either of them is a grantor of options, which breaches,
     individually or in the aggregate have, or insofar as
     reasonably can be foreseen, would have, a WPL Material
     Adverse Effect or an IES Material Adverse Effect, and such
     breaches shall not have been remedied within 20 days after
     receipt by WPL or IES, as the case may be, of notice in
     writing from Interstate, specifying the nature of such
     breaches and requesting that they be remedied;

              (ii)  WPL or IES (and/or its appropriate
     Subsidiaries) shall not have performed and complied with its

     or shall have failed to perform and comply with, in all
     material respects, its other agreements and covenants

     nature of such failure and requesting that it be remedied;
     or

             (iii)  the Board of Directors of WPL or IES or any
     committee thereof:

                    (A)  shall withdraw or modify in any manner
          adverse to Interstate its approval or recommendation of
          this Agreement, the IES Merger or the Interstate
          Merger,

                    (B)  shall fail to reaffirm such approval or
          recommendation upon Interstate's request,

                    (C)  shall approve or recommend any Business
          Combination involving WPL or IES other than the Merger

     herein or in any of the Stock Option Agreements pursuant to
     which either of them is a grantor of options, which
     breaches, individually or in the aggregate have or, insofar
     as reasonably can be foreseen, would have, an Interstate

     and such breaches shall not have been remedied within 20
     days after receipt by Interstate or IES, as the case may be,
     of notice in writing from WPL, specifying the nature of such
     breaches and requesting that they be remedied; 

                 (ii)  Interstate or IES (and/or its appropriate
     Subsidiaries) shall not have performed and complied with its
     agreements and covenants contained in Sections 7.3 and 7.4
     or shall have failed to perform and comply with, in all
     material respects, its other agreements and covenants
     hereunder or under the Stock Option Agreements, and such

     within 20 days after receipt by Interstate or IES, as the
     case may be, of notice in writing from WPL, specifying the
     nature of such failure and requesting that it be remedied;
     and 

               (iii)  the Board of Directors of Interstate or IES
     or any committee thereof: 

                    (A)  shall withdraw or modify in any manner

          for the shares of capital stock of Interstate or IES,
          in each case by or involving a party other than WPL or
          any of its Affiliates or 

                    (D)  shall resolve to take any of the actions
          specified in clause (A), (B) or (C).

          Section 10.2  Effect of Termination.  Subject to
Section 11.1(b), in the event of termination of this Agreement by
WPL, IES or Interstate pursuant to Section 10.1 there shall be no
liability on the part of either WPL, IES or Interstate or their
respective officers or directors hereunder, except that Section
8.1(b), Section 8.17, Section 10.3, Section 11.2 and Section 11.8
shall survive the termination.

          Section 10.3  Termination Fee; Expenses.

          (a)  Termination Fee Upon Breach or Withdrawal of
Approval.  If this Agreement is terminated at such time that this
Agreement is terminable pursuant to one or two (but not three) of
(x) Section 10.1(h)(i) or (ii), (y) Section 10.1(i)(i) or (ii) or
(z) Section 10.1(j)(i) or (ii), then:

               (i)  each breaching party shall promptly (but no
     later than five business days after receipt of notice from
     the non-breaching party or parties (other than AMW)) pay to
     the non-breaching party or parties in cash such breaching
     party's Participation Percentage (as hereinafter defined) of
     an amount equal to all documented out-of-pocket expenses and
     fees incurred by the non-breaching party or parties
     (including, without limitation, fees and expenses payable to
     all legal, accounting, financial, public relations and other
     professional advisors arising out of, in connection with or
     related to the Merger or the transactions contemplated by
     this Agreement) not in excess of $5 million for any non-
     breaching party; provided, however, that, if this Agreement
     is terminated by a party as a result of a willful breach by
     any other party, each non-breaching party may pursue any
     remedies available to it at law or in equity and shall, in
     addition to its documented out-of-pocket expenses and fees
     (which shall be paid as specified above and shall not be
     limited to $5 million for any non-breaching party), be
     entitled to retain such additional amounts as such non-
     breaching party may be entitled to receive at law or in
     equity; and

              (ii)  if

                    (A)  at the time of a breaching party's
          willful breach of this Agreement, there shall have been
          a third party tender offer for shares of, or a third
          party offer or proposal with respect to a Business
          Combination involving, such party or any of its
          Affiliates which at the time of such termination shall
          not have been rejected by such party and its board of
          directors or withdrawn by the third party, and

                    (B)  within two and one-half years of any
          termination by a non-breaching party, the breaching
          party or an Affiliate thereof becomes a Subsidiary of
          such offeror or a Subsidiary of an Affiliate of such
          offeror or accepts a written offer to consummate or
          consummates a Business Combination with such offeror or
          an Affiliate thereof,

     then such breaching party (jointly and severally with its
     Affiliates), at the closing (and as a condition to the
     closing) of such breaching party becoming such a Subsidiary
     or of such Business Combination, will pay to each non-
     breaching party (other than AMW) in cash such non-breaching
     party's Participation Percentage of an additional aggregate
     fee equal to $25 million, if WPL is the breaching party, $25
     million, if IES is the breaching party, or $12.5 million, if
     Interstate is the breaching party.

          (b)  Additional Termination Fee.  If

               (i)  this Agreement 

                    (A) is terminated by any party pursuant to
          Section 10.1(e), (f) or (g),

                    (B)  is terminated following a failure of the
          shareholders of any one of the necessary parties to
          grant the necessary approvals described in Section
          4.13, Section 5.13 and Section 6.13 or

                    (C)  is terminated as a result of any party's
          material breach of Section 8.4, and

            (ii)  at the time of such termination or prior to the
     meeting of such party's shareholders there shall have been a
     third-party tender offer for shares of, or a third-party
     offer or proposal with respect to a Business Combination
     involving, such party or any of its Affiliates which at the
     time of such termination or of the meeting of such party's
     shareholders shall not have been (A) rejected by such party
     and its board of directors or (B) withdrawn by the third
     party, and

              (iii)  within two and one-half years of any such
     termination described in clause (i) above, a Target Party
     (as defined herein) becomes a Subsidiary of such offeror or
     a Subsidiary of an Affiliate of such offeror or accepts a
     written offer to consummate or consummates a Business
     Combination with such offeror or an Affiliate thereof,

     then such Target Party (jointly and severally with its
     Affiliates), at the closing (and as a condition to the
     closing) of such Target Party becoming such a Subsidiary or
     of such Business Combination, will pay to each other party
     (other than AMW) in cash such other party's Participation
     Percentage of an aggregate termination fee equal to $25
     million, if WPL is the Target Party, $25 million, if IES is
     the Target Party, or $12.5 million, if Interstate is the
     Target Party, plus, in each case, the documented out-of-
     pocket fees and expenses incurred by each such non-breaching
     party (including, without limitation, fees and expenses
     payable to all legal, accounting, financial, public
     relations and other professional advisors arising out of, in
     connection with or related to the Merger or the transactions
     contemplated by this Agreement).

          (c)  Second Termination Fee.  If this Agreement is
terminated under circumstances that give rise to the payment of
any fee pursuant to Section 10.3(b) by any party, and thereafter,
within nine (9) months of such termination, either of the parties
that was not a Target Party at the time of such termination
becomes a Target Party (a "Second Target Party") of the same
entity, or an Affiliate thereof, that caused the original Target
Party to become such, then such Second Target Party (jointly and
severally with its Affiliates), upon the signing of a definitive
agreement relating to such a Business Combination, or, if no such
agreement is signed, then at the closing (and as a condition to
the closing) of such Second Target Party becoming such a
Subsidiary or of such Business Combination, will pay to the
remaining party (other than AMW) that is neither a Target Party
nor a Second Target Party (a "Non-Target Party")

               (i) a termination fee in cash equal to $25
     million, if WPL is the Second Target Party, $25 million, if
     IES is the Second Target Party, or $12.5 million, if
     Interstate is the Second Target Party, plus, in each case,
     any additional documented out-of-pocket fees and expenses
     incurred by the Non-Target Party (including, without
     limitation, fees and expenses payable to all legal,
     accounting, financial, public relations and other
     professional advisors arising out of, in connection with or
     related to the Merger or the transactions contemplated by
     this Agreement); and

               (ii)  the full amount of any termination fee paid
     to it by the first Target Party.

          (d)  Expenses.  The parties agree that the agreements
contained in this Section 10.3 are an integral part of the
transactions contemplated by the Agreement and constitute
liquidated damages and not a penalty.  If one party fails to
promptly pay to any other party any fee due hereunder, the
defaulting party shall pay the costs and expenses (including
legal fees and expenses) in connection with any action, including
the filing of any lawsuit or other legal action, taken to collect
payment, together with interest on the amount of any unpaid fee
at the publicly announced prime rate of Citibank, N.A. from the
date such fee was required to be paid.

          (e)  Limitation on Termination Fees.  Notwithstanding
anything herein to the contrary,

               (i)  the aggregate amount payable by WPL and its 
     Affiliates to IES and/or Interstate pursuant to Section
     10.3(a), Section 10.3(b) and the terms of the WPL/IES Stock
     Option Agreement and the WPL/Interstate Stock Option
     Agreement shall not exceed $40 million,

               (ii) the aggregate amount payable by IES and its 
     Affiliates pursuant to Section 10.3(a), Section 10.3(b) and
     the terms of the IES/WPL Stock Option Agreement and the
     IES/Interstate Stock Option Agreement shall not exceed $40
     million, and 

              (iii) the aggregate amount payable by Interstate 
     and its Affiliates under Section 10.3(a), Section 10.3(b)
     and the terms of the Interstate/WPL Stock Option Agreement
     and the Interstate/IES Stock Option Agreement shall not
     exceed $20 million

(exclusive, in each case, of reimbursement for fees and expenses
payable pursuant to this Section 10.3).  For purposes of this
Section 10.3(d), the amount payable pursuant to the terms of the
Stock Option Agreements shall be the amount paid pursuant to
Section 5 and/or Section 8(a)(i) and 8(a)(ii) thereof.

          (f)  Certain Definitions.  

               (i)  Participation Percentage.  A party's
     participation percentage ("Participation Percentage") shall
     be one hundred percent (100%) if only one party is required
     to pay or entitled to receive its Participation Percentage
     pursuant to the terms of this Section 10.3.  If two parties
     are required to pay or entitled to receive their respective
     Participation Percentages, each party's Participation
     Percentage shall equal a fraction (expressed as a
     percentage), the numerator of which shall be, in the case of
     IES or Interstate, the number of shares of WPL Common Stock
     which would be issuable (on a fully diluted basis) to such
     party's shareholders, or, in the case of WPL, the number of
     shares of WPL Common Stock (on a fully diluted basis) that
     would have been retained by its shareholders, had the
     Effective Time occurred at the time this Agreement is
     terminated and the denominator of which shall be, the
     aggregate number of shares of WPL Common Stock that would be

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among WPL Holdings, Inc., a
corporation organized under the laws of the State of Wisconsin
("OPTION GRANTOR" or the "Company") and IES Industries Inc., a
corporation organized under the laws of the State of Iowa
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, Interstate
Power Company, a corporation organized under the laws of the
State of Delaware ("Interstate"), and AMW Acquisition, Inc., a
wholly-owned subsidiary of OPTION GRANTOR organized under the
laws of the State of Delaware ("AMW"), are entering into an
Agreement and Plan of Merger, dated as of November 10, 1995, (the
"Merger Agreement"), which provides, inter alia, upon the terms
and subject to the conditions thereof, for the merger of OPTION
HOLDER with and into OPTION GRANTOR in accordance with the laws
of the States of Wisconsin and Iowa (the "IES Merger"), and the
merger of AMW with and into Interstate in accordance with the
laws of the State of Delaware (the "Interstate Merger", and
together with the IES Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and Interstate are
entering into certain stock option agreements dated as of the
date hereof, of which this Agreement is one, whereby the parties
hereto grant each other an option with respect to certain shares
of each other's common stock on the terms and subject to the
conditions set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
4.4(c) of the WPL Disclosure Schedule to the Merger Agreement and
by OPTION HOLDER as set forth in Section 5.4(c) of the IES
Disclosure Schedule to the Merger Agreement, OPTION GRANTOR
hereby grants OPTION HOLDER an irrevocable option (the "OPTION
GRANTOR Option") to purchase up to that number of shares, subject
to adjustment as provided in Section 12 (the "OPTION GRANTOR
Shares"), of common stock, par value $.01 per share, of OPTION
GRANTOR (the "OPTION GRANTOR Common Stock") equal to a percentage
(the "Option Shares Percentage"), which Option Shares Percentage
is equal to the OPTION HOLDER's Participation Percentage as
defined below in subsection (e), of 6,123,944 shares of OPTION
GRANTOR Common Stock (being 19.9% of the number of shares of
OPTION GRANTOR Common Stock issued and outstanding as of November
10, 1995, the "Initial Number") in the manner set forth below, at
a price (the "Exercise Price") per OPTION GRANTOR Share of
$30.675 (which is equal to the Fair Market Value (as defined
below) of a OPTION GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, no par value, of OPTION HOLDER ("OPTION HOLDER
     Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it

     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such

     the Merger Agreement upon or during the continuance of a
     Trigger Event (or if, at the expiration of such 180 day
     period, the OPTION GRANTOR Option cannot be exercised by

     regulation, ten business days after such impediment to
     exercise shall have been removed or shall have become final
     and not subject to appeal, but in no event under this clause
     (iii) later than May 10, 1998); and

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

          (i)  (A)  The difference between the "Market/Offer
     Price" (as defined below) for shares of OPTION GRANTOR
     Common Stock as of the date OPTION HOLDER gives notice of
     its intent to exercise its rights under this Section 8 and
     the Exercise Price, multiplied by the number of OPTION
     GRANTOR Shares purchasable pursuant to the OPTION GRANTOR
     Option (or portion thereof with respect to which OPTION
     HOLDER is exercising its rights under this Section 8), but
     only if the Market/Offer Price is greater than the Exercise
     Price.

                    (B)  for purposes of this Agreement,
     "Market/Offer Price") shall mean, as of any date, the higher
     of (I) the price per share offered as of such date pursuant
     to any tender or exchange offer or other offer with respect
     to a Business Combination involving OPTION GRANTOR as the
     Target Party which was made prior to such date and not
     terminated or withdrawn as of such date and (II) the Fair
     Market Value of OPTION GRANTOR Common Stock as of such date.

          (ii) (A)  the product of (I) the sum of (a) the
     Exercise Price paid by OPTION HOLDER per OPTION GRANTOR
     Share acquired pursuant to the OPTION GRANTOR Option, and
     (b) the difference between the "Offer Price" (as defined
     below) and the Exercise Price, but only if the offer Price
     is greater that the Exercise Price, and (II) the number of
     OPTION GRANTOR Shares so to be repurchased pursuant to this
     Section 8.

                    (B)  For purposes of this clause (ii), the
     "Offer Price" shall be the highest price per share offered
     pursuant to a tender or exchange offer or other Business
     Combination offer involving OPTION GRANTOR as the Target
     Party during the Repurchase Period prior to the delivery by
     OPTION HOLDER of a notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.
          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii)  the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
this Section 11, the parties agree

          (i)  to indemnify each other and the underwriters in
     the customary manner,

          (ii) to enter into an underwriting agreement in form
     and substance customary for transactions of such type with
     the Manager and the other underwriters participating in such
     offering, and

          (iii)     to take all further actions which shall be
     reasonably necessary to effect such registration and sale
     (including if the Manager deems it necessary, participating
     in road-show presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,
which shall remain in full force and effect.

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to
specific performance of such provision or part hereof or to any
other remedy, including but not limited to money damages, for
breach hereof or of any other provision of this Agreement or part
hereof as the result of such holding or order.

          17.  NOTICES.  All notices and other communications
hereunder shall be in writing and shall be deemed given if (a)
delivered personally, or (b) if sent by overnight courier service

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among WPL Holdings, Inc., a
corporation organized under the laws of the State of Wisconsin
("OPTION GRANTOR" or the "Company") and Interstate Power Company,
a corporation organized under the laws of the State of Delaware
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, IES Industries
Inc., a corporation organized under the laws of the State of Iowa
("IES"), and AMW Acquisition, Inc., a wholly-owned subsidiary of
OPTION GRANTOR organized under the laws of the State of Delaware
("AMW"), are entering into an Agreement and Plan of Merger, dated
as of November 10, 1995, (the "Merger Agreement"), which
provides, inter alia, upon the terms and subject to the
conditions thereof, for the merger of IES with and into OPTION
GRANTOR in accordance with the laws of the States of Wisconsin
and Iowa (the "IES Merger"), and the merger of AMW with and into
OPTION HOLDER in accordance with the laws of the State of
Delaware (the "Interstate Merger", and together with the IES
Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and IES are entering
into certain stock option agreements dated as of the date hereof,
of which this Agreement is one, whereby the parties hereto grant
each other an option with respect to certain shares of each
other's common stock on the terms and subject to the conditions
set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
4.4(c) of the WPL Disclosure Schedule to the Merger Agreement and
by OPTION HOLDER as set forth in Section 6.4(c) of the Interstate
Disclosure Schedule to the Merger Agreement, OPTION GRANTOR
hereby grants OPTION HOLDER an irrevocable option (the "OPTION
GRANTOR Option") to purchase up to that number of shares, subject
to adjustment as provided in Section 12 (the "OPTION GRANTOR
Shares"), of common stock, par value $.01 per share, of OPTION
GRANTOR (the "OPTION GRANTOR Common Stock") equal to a percentage
(the "Option Shares Percentage"), which Option Shares Percentage
is equal to the OPTION HOLDER's Participation Percentage as
defined below in subsection (e), of 6,123,944 shares of OPTION
GRANTOR Common Stock (being 19.9% of the number of shares of
OPTION GRANTOR Common Stock issued and outstanding as of November
10, 1995, the "Initial Number") in the manner set forth below, at
a price (the "Exercise Price") per OPTION GRANTOR Share of
$30.675 (which is equal to the Fair Market Value (as defined
below) of a OPTION GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, $3.50 par value, of OPTION HOLDER ("OPTION
     HOLDER Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it
     wishes to purchase.

               (iii)     Upon the giving by OPTION HOLDER to
     OPTION GRANTOR of the Exercise Notice and the tender of the
     applicable aggregate Exercise Price, OPTION HOLDER, to the
     extent permitted by law and OPTION GRANTOR's organizational
     documents, and provided that the conditions to OPTION
     GRANTOR's obligation to issue the OPTION GRANTOR Shares to
     OPTION HOLDER hereunder set forth in Section 3 have been
     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such
     exercise, notwithstanding that the stock transfer books of
     OPTION GRANTOR shall then be closed or that certificates
     representing such OPTION GRANTOR Shares shall not then be
     actually delivered to OPTION HOLDER.

               (iv) Each closing of a purchase of OPTION GRANTOR
     Shares (a "Closing") shall occur at a place, on a date, and
     at a time designated by OPTION HOLDER in an Exercise Notice
     delivered at least two business days prior to the date of
     the Closing.

          (c)  The OPTION GRANTOR Option shall terminate upon the
earliest to occur of:

               (i)  the Effective Time of the Merger;

               (ii) the termination of the Merger Agreement
     pursuant to Section 10.1 thereof, other than under
     circumstances which also constitute a Trigger Event under
     this Agreement; 

               (iii)     180 days following any termination of
     the Merger Agreement upon or during the continuance of a
     Trigger Event (or if, at the expiration of such 180 day
     period, the OPTION GRANTOR Option cannot be exercised by
     reason of any applicable judgment, decree, order, law or
     regulation, ten business days after such impediment to
     exercise shall have been removed or shall have become final
     and not subject to appeal, but in no event under this clause
     (iii) later than May 10, 1998); and

               (iv) payment by OPTION GRANTOR of the Trigger
     Payment set forth in Section 5 of this Agreement to OPTION
     HOLDER.

          (d)  Notwithstanding the foregoing, the OPTION GRANTOR
Option may not be exercised if (i) OPTION HOLDER is in material
breach of any of its representations or warranties, or in
material breach of any of its covenants or agreements, contained
in this Agreement or in the Merger Agreement, or (ii) a Trigger
Payment has been paid pursuant to Section 5 of this Agreement or
demand therefor has been made and not withdrawn.

          3.   CONDITIONS TO CLOSING.  The obligation of OPTION
GRANTOR to issue the OPTION GRANTOR Shares to OPTION HOLDER
hereunder is subject to the conditions that

          (a)  all waiting periods, if any, under the HSR Act
applicable to the issuance and acquisition of the OPTION GRANTOR
Shares hereunder shall have expired or have been terminated;

          (b)  the OPTION GRANTOR Shares, and any OPTION HOLDER
Shares which are issued in payment of the Exercise Price, shall
have been approved for listing on the NYSE subject only to
official notice of issuance;

          (c)  all consents, approvals, orders or authorizations
of, or registrations, declarations or filings with, any federal,
state or local administrative agency or commission or other
federal, state or local Governmental Authority, if any, required
in connection with the issuance by OPTION GRANTOR and the
acquisition by OPTION HOLDER of the OPTION GRANTOR Shares
hereunder shall have been obtained or made, including, without
limitation, the approval of the SEC under Sections 9 and 10 of
the Public Utility Holding Company Act of 1935, as amended (the
"1935 Act"), the approval of the Public Service Commission of
Wisconsin of the issuance of the OPTION GRANTOR Shares by OPTION
GRANTOR and, if applicable, the acquisition of OPTION GRANTOR
Shares by OPTION HOLDER, and the approval of the Iowa Utilities

order by any court of competent jurisdiction prohibiting or
otherwise restraining such issuance shall be in effect.

The condition set forth in paragraph (b) above may be waived by
OPTION GRANTOR, in the case of OPTION HOLDER Shares, and by
OPTION HOLDER, in the case of OPTION GRANTOR Shares, in the sole

          (a)  OPTION GRANTOR shall deliver to OPTION HOLDER or

               (ii) subject to the condition in Section 1(b)(ii),
     delivery of a certificate or certificates representing the
     number of OPTION HOLDER Shares being issued by OPTION HOLDER

     Section 4(c).

          (c)  In the event that OPTION HOLDER issues OPTION
HOLDER Shares to OPTION GRANTOR in consideration of OPTION
GRANTOR Shares pursuant to Section 4(b)(ii), the number of OPTION
HOLDER Shares to be so issued shall be equal to the quotient
obtained by dividing:

               (i)  the product of (x) the number of OPTION
     GRANTOR Shares with respect to which the OPTION GRANTOR
     Option is being exercised and (y) the Exercise Price, by

               (ii) the Fair Market Value of the OPTION HOLDER
     Shares as of the date immediately preceding the date the

have occurred and any regulatory approval or order required for
the issuance by OPTION GRANTOR, or the acquisition by OPTION
HOLDER, of the OPTION GRANTOR Option pursuant to Section 1 hereof
shall not have been obtained, OPTION HOLDER shall have the right
to receive, and OPTION GRANTOR shall pay to OPTION HOLDER, an
amount (the "Trigger Payment") equal to the product of

     (i)  the maximum number of OPTION GRANTOR Shares that would
     have been subject to purchase by OPTION HOLDER upon exercise
     of the OPTION GRANTOR Option pursuant to Sections 1 and 2
     hereof if all such regulatory approvals or orders had been
     obtained, and

     (ii)  the difference between (A) the Market/Offer Price (as
     defined herein), determined as of the date on which notice
     of demand for the Trigger Payment is given by OPTION HOLDER,
     and (B) the Exercise Price (but only if such Market/Offer
     Price is higher than such Exercise Price).

Demand for the Trigger Payment shall be given by notice in
accordance with the provisions of Section 17 hereof.  The Trigger
Payment shall be paid to OPTION HOLDER by OPTION GRANTOR on the
Payment Date (as defined herein), by wire transfer of immediately
available funds to an account to be designated in writing by
OPTION HOLDER not less than two business days before the Payment
Date.

          (b)  Payment Date.  For purposes of this Section 5,

Agreement as a result of the occurrence of the Trigger Event
referred to in subsection (a) of this Section 5.

          (c)  Certain Conditions.  OPTION GRANTOR shall have no
obligation to pay the Trigger Payment if OPTION HOLDER is in
material breach of any of its representations or warranties, or
in material breach of any of its covenants or agreements,
contained in this Agreement or in the Merger Agreement.

          6.   REPRESENTATIONS AND WARRANTIES OF OPTION GRANTOR.

pursuant to

               (i)  any provision of the OPTION GRANTOR Articles

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

          (i)  (A)  The difference between the "Market/Offer
     Price" (as defined below) for shares of OPTION GRANTOR
     Common Stock as of the date OPTION HOLDER gives notice of
     its intent to exercise its rights under this Section 8 and
     the Exercise Price, multiplied by the number of OPTION
     GRANTOR Shares purchasable pursuant to the OPTION GRANTOR
     Option (or portion thereof with respect to which OPTION
     HOLDER is exercising its rights under this Section 8), but
     only if the Market/Offer Price is greater than the Exercise
     Price.

                    (B)  for purposes of this Agreement,
     "Market/Offer Price") shall mean, as of any date, the higher
     of (I) the price per share offered as of such date pursuant
     to any tender or exchange offer or other offer with respect
     to a Business Combination involving OPTION GRANTOR as the
     Target Party which was made prior to such date and not
     terminated or withdrawn as of such date and (II) the Fair
     Market Value of OPTION GRANTOR Common Stock as of such date.

          (ii) (A)  the product of (I) the sum of (a) the
     Exercise Price paid by OPTION HOLDER per OPTION GRANTOR
     Share acquired pursuant to the OPTION GRANTOR Option, and
     (b) the difference between the "Offer Price" (as defined
     below) and the Exercise Price, but only if the offer Price
     is greater that the Exercise Price, and (II) the number of
     OPTION GRANTOR Shares so to be repurchased pursuant to this
     Section 8.

                    (B)  For purposes of this clause (ii), the
     "Offer Price" shall be the highest price per share offered
     pursuant to a tender or exchange offer or other Business
     Combination offer involving OPTION GRANTOR as the Target
     Party during the Repurchase Period prior to the delivery by
     OPTION HOLDER of a notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.
          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii)  the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
this Section 11, the parties agree

          (i)  to indemnify each other and the underwriters in
     the customary manner,

          (ii) to enter into an underwriting agreement in form
     and substance customary for transactions of such type with
     the Manager and the other underwriters participating in such
     offering, and

          (iii)     to take all further actions which shall be
     reasonably necessary to effect such registration and sale
     (including if the Manager deems it necessary, participating
     in road-show presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,
which shall remain in full force and effect.

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to
specific performance of such provision or part hereof or to any
other remedy, including but not limited to money damages, for
breach hereof or of any other provision of this Agreement or part
hereof as the result of such holding or order.

          17.  NOTICES.  All notices and other communications

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among IES Industries Inc., a
corporation organized under the laws of the State of Iowa
("OPTION GRANTOR" or the "Company") and WPL Holdings, Inc., a
corporation organized under the laws of the State of Wisconsin
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, Interstate
Power Company, a corporation organized under the laws of the
State of Delaware ("Interstate"), and AMW Acquisition, Inc., a
wholly-owned subsidiary of OPTION HOLDER organized under the laws
of the State of Delaware ("AMW"), are entering into an Agreement
and Plan of Merger, dated as of November 10, 1995, (the "Merger
Agreement"), which provides, inter alia, upon the terms and
subject to the conditions thereof, for the merger of OPTION
GRANTOR with and into OPTION HOLDER in accordance with the laws
of the States of Wisconsin and Iowa (the "IES Merger"), and the
merger of AMW with and into Interstate in accordance with the
laws of the State of Delaware (the "Interstate Merger", and
together with the IES Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and Interstate are
entering into certain stock option agreements dated as of the
date hereof, of which this Agreement is one, whereby the parties
hereto grant each other an option with respect to certain shares
of each other's common stock on the terms and subject to the
conditions set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
5.4(c) of the IES Disclosure Schedule to the Merger Agreement and
by OPTION HOLDER as set forth in Section 4.4(c) of the WPL
Disclosure Schedule to the Merger Agreement, OPTION GRANTOR
hereby grants OPTION HOLDER an irrevocable option (the "OPTION
GRANTOR Option") to purchase up to that number of shares, subject
to adjustment as provided in Section 12 (the "OPTION GRANTOR
Shares"), of common stock, no par value, of OPTION GRANTOR (the
"OPTION GRANTOR Common Stock") equal to a percentage (the "Option
Shares Percentage"), which Option Shares Percentage is equal to
the OPTION HOLDER's Participation Percentage as defined below in
subsection (e), of 5,861,115 shares of OPTION GRANTOR Common
Stock (being 19.9% of the number of shares of OPTION GRANTOR
Common Stock issued and outstanding as of November 10, 1995, the
"Initial Number") in the manner set forth below, at a price (the
"Exercise Price") per OPTION GRANTOR Share of $26.7125 (which is
equal to the Fair Market Value (as defined below) of a OPTION
GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, $.01 par value, of OPTION HOLDER ("OPTION
     HOLDER Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it
     wishes to purchase.

               (iii)     Upon the giving by OPTION HOLDER to
     OPTION GRANTOR of the Exercise Notice and the tender of the
     applicable aggregate Exercise Price, OPTION HOLDER, to the
     extent permitted by law and OPTION GRANTOR's organizational
     documents, and provided that the conditions to OPTION
     GRANTOR's obligation to issue the OPTION GRANTOR Shares to
     OPTION HOLDER hereunder set forth in Section 3 have been
     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such
     exercise, notwithstanding that the stock transfer books of
     OPTION GRANTOR shall then be closed or that certificates
     representing such OPTION GRANTOR Shares shall not then be
     actually delivered to OPTION HOLDER.

               (iv) Each closing of a purchase of OPTION GRANTOR
     Shares (a "Closing") shall occur at a place, on a date, and
     at a time designated by OPTION HOLDER in an Exercise Notice
     delivered at least two business days prior to the date of
     the Closing.

          (c)  The OPTION GRANTOR Option shall terminate upon the
earliest to occur of:

               (i)  the Effective Time of the Merger;

               (ii) the termination of the Merger Agreement
     pursuant to Section 10.1 thereof, other than under
     circumstances which also constitute a Trigger Event under
     this Agreement; 

               (iii) 180 days following any termination of the
     Merger Agreement upon or during the continuance of a Trigger
     Event (or if, at the expiration of such 180 day period, the
     OPTION GRANTOR Option cannot be exercised by reason of any
     applicable judgment, decree, order, law or regulation, ten
     business days after such impediment to exercise shall have
     been removed or shall have become final and not subject to
     appeal, but in no event under this clause (iii) later than
     May 10, 1998); and

               (iv) payment by OPTION GRANTOR of the Trigger
     Payment set forth in Section 5 of this Agreement to OPTION
     HOLDER.

          (d)  Notwithstanding the foregoing, the OPTION GRANTOR
Option may not be exercised if (i) OPTION HOLDER is in material
breach of any of its representations or warranties, or in
material breach of any of its covenants or agreements, contained
in this Agreement or in the Merger Agreement, or (ii) a Trigger
Payment has been paid pursuant to Section 5 of this Agreement or
demand therefor has been made and not withdrawn.

          3.   CONDITIONS TO CLOSING.  The obligation of OPTION
GRANTOR to issue the OPTION GRANTOR Shares to OPTION HOLDER
hereunder is subject to the conditions that

          (a)  all waiting periods, if any, under the HSR Act
applicable to the issuance and acquisition of the OPTION GRANTOR
Shares hereunder shall have expired or have been terminated;

          (b)  the OPTION GRANTOR Shares, and any OPTION HOLDER
Shares which are issued in payment of the Exercise Price, shall
have been approved for listing on the NYSE subject only to
official notice of issuance;

          (c)  all consents, approvals, orders or authorizations
of, or registrations, declarations or filings with, any federal,
state or local administrative agency or commission or other
federal, state or local Governmental Authority, if any, required
in connection with the issuance by OPTION GRANTOR and the
acquisition by OPTION HOLDER of the OPTION GRANTOR Shares
hereunder shall have been obtained or made, including, without
limitation, the approval of the SEC under Sections 9 and 10 of
the Public Utility Holding Company Act of 1935, as amended (the
"1935 Act"), the approval of the Iowa Utilities Board of the
issuance of the OPTION GRANTOR Shares by OPTION GRANTOR and, if
applicable, the acquisition of OPTION GRANTOR Shares by OPTION
HOLDER, and the approval of the Public Service Commission of
Wisconsin of the acquisition of the OPTION GRANTOR Shares by
OPTION HOLDER and, if applicable, the acquisition by OPTION
GRANTOR of the OPTION HOLDER Shares constituting the Exercise
Price hereunder; and

          (d)  no preliminary or permanent injunction or other
order by any court of competent jurisdiction prohibiting or
otherwise restraining such issuance shall be in effect.

The condition set forth in paragraph (b) above may be waived by
OPTION GRANTOR, in the case of OPTION HOLDER Shares, and by
OPTION HOLDER, in the case of OPTION GRANTOR Shares, in the sole
discretion of the waiving party.

          4.   CLOSING.  At any Closing,

          (a)  OPTION GRANTOR shall deliver to OPTION HOLDER or
its designee a single certificate in definitive form representing
the number of OPTION GRANTOR Shares designated by OPTION HOLDER
in its Exercise Notice, such certificate to be registered in the
name of OPTION HOLDER and to bear the legend set forth in Section
13; and

          (b)  OPTION HOLDER shall deliver to OPTION GRANTOR the
aggregate price for the OPTION GRANTOR Shares so designated and
being purchased by

               (i)  wire transfer of immediately available funds
     or certified check or bank check, or

               (ii) subject to the condition in Section 1(b)(ii),
     delivery of a certificate or certificates representing the
     number of OPTION HOLDER Shares being issued by OPTION HOLDER
     in consideration thereof, determined in accordance with
     Section 4(c).

          (c)  In the event that OPTION HOLDER issues OPTION
HOLDER Shares to OPTION GRANTOR in consideration of OPTION
GRANTOR Shares pursuant to Section 4(b)(ii), the number of OPTION
HOLDER Shares to be so issued shall be equal to the quotient
obtained by dividing:

               (i)  the product of (x) the number of OPTION
     GRANTOR Shares with respect to which the OPTION GRANTOR
     Option is being exercised and (y) the Exercise Price, by

               (ii) the Fair Market Value of the OPTION HOLDER
     Shares as of the date immediately preceding the date the
     Exercise Notice is delivered to OPTION GRANTOR.

          (d)  OPTION GRANTOR shall pay all expenses, and any and
all Federal, state and local taxes and other charges that may be
payable in connection with the preparation, issue and delivery of
stock certificates under this Section 4.

          5.   TRIGGER PAYMENT.

          (a)  Trigger Payment.  Subject to the provisions of
Section 10.3(e) of the Merger Agreement, if a Trigger Event shall
have occurred and any regulatory approval or order required for
the issuance by OPTION GRANTOR, or the acquisition by OPTION
HOLDER, of the OPTION GRANTOR Option pursuant to Section 1 hereof
shall not have been obtained, OPTION HOLDER shall have the right
to receive, and OPTION GRANTOR shall pay to OPTION HOLDER, an
amount (the "Trigger Payment") equal to the product of

     (i)  the maximum number of OPTION GRANTOR Shares that would
     have been subject to purchase by OPTION HOLDER upon exercise
     of the OPTION GRANTOR Option pursuant to Sections 1 and 2
     hereof if all such regulatory approvals or orders had been
     obtained, and

     (ii)  the difference between (A) the Market/Offer Price (as
     defined herein), determined as of the date on which notice
     of demand for the Trigger Payment is given by OPTION HOLDER,
     and (B) the Exercise Price (but only if such Market/Offer
     Price is higher than such Exercise Price).

Demand for the Trigger Payment shall be given by notice in
accordance with the provisions of Section 17 hereof.  The Trigger
Payment shall be paid to OPTION HOLDER by OPTION GRANTOR on the
Payment Date (as defined herein), by wire transfer of immediately
available funds to an account to be designated in writing by

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

            (i)  (A)  The difference between the "Market/Offer
     Price" (as defined below) for shares of OPTION GRANTOR
     Common Stock as of the date OPTION HOLDER gives notice of
     its intent to exercise its rights under this Section 8 and
     the Exercise Price, multiplied by the number of OPTION
     GRANTOR Shares purchasable pursuant to the OPTION GRANTOR
     Option (or portion thereof with respect to which OPTION
     HOLDER is exercising its rights under this Section 8), but
     only if the Market/Offer Price is greater than the Exercise
     Price.

               (B)  for purposes of this Agreement, "Market/Offer
     Price") shall mean, as of any date, the higher of (I) the
     price per share offered as of such date pursuant to any
     tender or exchange offer or other offer with respect to a
     Business Combination involving OPTION GRANTOR as the Target
     Party which was made prior to such date and not terminated
     or withdrawn as of such date and (II) the Fair Market Value
     of OPTION GRANTOR Common Stock as of such date.

          (ii) (A)  the product of (I) the sum of (a) the
     Exercise Price paid by OPTION HOLDER per OPTION GRANTOR
     Share acquired pursuant to the OPTION GRANTOR Option, and
     (b) the difference between the "Offer Price" (as defined
     below) and the Exercise Price, but only if the offer Price
     is greater that the Exercise Price, and (II) the number of
     OPTION GRANTOR Shares so to be repurchased pursuant to this
     Section 8.

               (B)  For purposes of this clause (ii), the "Offer
     Price" shall be the highest price per share offered pursuant
     to a tender or exchange offer or other Business Combination
     offer involving OPTION GRANTOR as the Target Party during
     the Repurchase Period prior to the delivery by OPTION HOLDER
     of a notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.

          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii)  the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
     this Section 11, the parties agree

          (i)  to indemnify each other and the underwriters in
     the customary manner,

          (ii) to enter into an underwriting agreement in form
     and substance customary for transactions of such type with
     the Manager and the other underwriters participating in such
     offering, and

          (iii)  to take all further actions which shall be
     reasonably necessary to effect such registration and sale
     (including if the Manager deems it necessary, participating
     in road-show presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to
specific performance of such provision or part hereof or to any
other remedy, including but not limited to money damages, for
breach hereof or of any other provision of this Agreement or part
hereof as the result of such holding or order.

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among IES Industries Inc., a
corporation organized under the laws of the State of Iowa
("OPTION GRANTOR" or the "Company") and Interstate Power Company,
a corporation organized under the laws of the State of Delaware
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, WPL Holdings,
Inc., a corporation organized under the laws of the State of
Wisconsin ("WPL"), and AMW Acquisition, Inc., a wholly-owned
subsidiary of WPL organized under the laws of the State of
Delaware ("AMW"), are entering into an Agreement and Plan of
Merger, dated as of November 10, 1995, (the "Merger Agreement"),
which provides, inter alia, upon the terms and subject to the
conditions thereof, for the merger of OPTION GRANTOR with and
into WPL in accordance with the laws of the States of Wisconsin
and Iowa (the "IES Merger"), and the merger of AMW with and into
OPTION HOLDER in accordance with the laws of the State of
Delaware (the "Interstate Merger", and together with the IES
Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and WPL are entering
into certain stock option agreements dated as of the date hereof,
of which this Agreement is one, whereby the parties hereto grant
each other an option with respect to certain shares of each
other's common stock on the terms and subject to the conditions
set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
5.4(c) of the IES Disclosure Schedule to the Merger Agreement and
by OPTION HOLDER as set forth in Section 6.4(c) of the Interstate
Disclosure Schedule to the Merger Agreement, OPTION GRANTOR
hereby grants OPTION HOLDER an irrevocable option (the "OPTION
GRANTOR Option") to purchase up to that number of shares, subject
to adjustment as provided in Section 12 (the "OPTION GRANTOR
Shares"), of common stock, no par value, of OPTION GRANTOR (the
"OPTION GRANTOR Common Stock") equal to a percentage (the "Option
Shares Percentage"), which Option Shares Percentage is equal to
the OPTION HOLDER's Participation Percentage as defined below in
subsection (e), of 5,861,115 shares of OPTION GRANTOR Common
Stock (being 19.9% of the number of shares of OPTION GRANTOR
Common Stock issued and outstanding as of November 10, 1995, the
"Initial Number") in the manner set forth below, at a price (the
"Exercise Price") per OPTION GRANTOR Share of $26.7125 (which is
equal to the Fair Market Value (as defined below) of a OPTION
GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, $3.50 par value, of OPTION HOLDER ("OPTION
     HOLDER Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it
     wishes to purchase.

               (iii)     Upon the giving by OPTION HOLDER to
     OPTION GRANTOR of the Exercise Notice and the tender of the
     applicable aggregate Exercise Price, OPTION HOLDER, to the
     extent permitted by law and OPTION GRANTOR's organizational
     documents, and provided that the conditions to OPTION
     GRANTOR's obligation to issue the OPTION GRANTOR Shares to
     OPTION HOLDER hereunder set forth in Section 3 have been
     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such
     exercise, notwithstanding that the stock transfer books of
     OPTION GRANTOR shall then be closed or that certificates
     representing such OPTION GRANTOR Shares shall not then be
     actually delivered to OPTION HOLDER.

               (iv) Each closing of a purchase of OPTION GRANTOR
     Shares (a "Closing") shall occur at a place, on a date, and
     at a time designated by OPTION HOLDER in an Exercise Notice
     delivered at least two business days prior to the date of
     the Closing.

          (c)  The OPTION GRANTOR Option shall terminate upon the
earliest to occur of:

               (i)  the Effective Time of the Merger;

               (ii) the termination of the Merger Agreement
     pursuant to Section 10.1 thereof, other than under
     circumstances which also constitute a Trigger Event under
     this Agreement; 

               (iii)     180 days following any termination of
     the Merger Agreement upon or during the continuance of a
     Trigger Event (or if, at the expiration of such 180 day
     period, the OPTION GRANTOR Option cannot be exercised by
     reason of any applicable judgment, decree, order, law or
     regulation, ten business days after such impediment to
     exercise shall have been removed or shall have become final
     and not subject to appeal, but in no event under this clause
     (iii) later than May 10, 1998); and

               (iv) payment by OPTION GRANTOR of the Trigger
     Payment set forth in Section 5 of this Agreement to OPTION
     HOLDER.

          (d)  Notwithstanding the foregoing, the OPTION GRANTOR
Option may not be exercised if (i) OPTION HOLDER is in material
breach of any of its representations or warranties, or in
material breach of any of its covenants or agreements, contained
in this Agreement or in the Merger Agreement, or (ii) a Trigger
Payment has been paid pursuant to Section 5 of this Agreement or
demand therefor has been made and not withdrawn.

          3.   CONDITIONS TO CLOSING.  The obligation of OPTION
GRANTOR to issue the OPTION GRANTOR Shares to OPTION HOLDER
hereunder is subject to the conditions that

          (a)  all waiting periods, if any, under the HSR Act
applicable to the issuance and acquisition of the OPTION GRANTOR
Shares hereunder shall have expired or have been terminated;

          (b)  the OPTION GRANTOR Shares, and any OPTION HOLDER
Shares which are issued in payment of the Exercise Price, shall
have been approved for listing on the NYSE subject only to
official notice of issuance;

of, or registrations, declarations or filings with, any federal,

in connection with the issuance by OPTION GRANTOR and the
acquisition by OPTION HOLDER of the OPTION GRANTOR Shares

of the OPTION GRANTOR Shares by OPTION GRANTOR and, if
applicable, the acquisition of OPTION GRANTOR Shares by OPTION

Minnesota Public Utilities Commission and the Illinois Commerce
Commission of the acquisition of the OPTION GRANTOR Shares by
OPTION HOLDER and, if applicable, the acquisition by OPTION
GRANTOR of the OPTION HOLDER Shares constituting the Exercise
Price hereunder; and

          (d)  no preliminary or permanent injunction or other
order by any court of competent jurisdiction prohibiting or
otherwise restraining such issuance shall be in effect.

The condition set forth in paragraph (b) above may be waived by
OPTION GRANTOR, in the case of OPTION HOLDER Shares, and by
OPTION HOLDER, in the case of OPTION GRANTOR Shares, in the sole
discretion of the waiving party.

          4.   CLOSING.  At any Closing,

          (a)  OPTION GRANTOR shall deliver to OPTION HOLDER or
its designee a single certificate in definitive form representing

in its Exercise Notice, such certificate to be registered in the
name of OPTION HOLDER and to bear the legend set forth in Section
13; and

          (b)  OPTION HOLDER shall deliver to OPTION GRANTOR the
aggregate price for the OPTION GRANTOR Shares so designated and
being purchased by

               (i)  wire transfer of immediately available funds
     or certified check or bank check, or

               (ii) subject to the condition in Section 1(b)(ii),
     delivery of a certificate or certificates representing the
     number of OPTION HOLDER Shares being issued by OPTION HOLDER
     in consideration thereof, determined in accordance with
     Section 4(c).

          (c)  In the event that OPTION HOLDER issues OPTION
HOLDER Shares to OPTION GRANTOR in consideration of OPTION
GRANTOR Shares pursuant to Section 4(b)(ii), the number of OPTION
HOLDER Shares to be so issued shall be equal to The quotient
obtained by dividing:

               (i)  the product of (x) the number of OPTION
     GRANTOR Shares with respect to which the OPTION GRANTOR
     Option is being exercised and (y) the Exercise Price, by

               (ii) the Fair Market Value of the OPTION HOLDER
     Shares as of the date immediately preceding the date the

          (a)  Trigger Payment.  Subject to the provisions of
Section 10.3(e) of the Merger Agreement, if a Trigger Event shall
have occurred and any regulatory approval or order required for
the issuance by OPTION GRANTOR, or the acquisition by OPTION
HOLDER, of the OPTION GRANTOR Option pursuant to Section 1 hereof
shall not have been obtained, OPTION HOLDER shall have the right
to receive, and OPTION GRANTOR shall pay to OPTION HOLDER, an
amount (the "Trigger Payment") equal to the product of

     (i)  the maximum number of OPTION GRANTOR Shares that would
     have been subject to purchase by OPTION HOLDER upon exercise
     of the OPTION GRANTOR Option pursuant to Sections 1 and 2
     hereof if all such regulatory approvals or orders had been
     obtained, and

     (ii)  the difference between (A) the Market/Offer Price (as
     defined herein), determined as of the date on which notice
     of demand for the Trigger Payment is given by OPTION HOLDER,
     and (B) the Exercise Price (but only if such Market/Offer
     Price is higher than such Exercise Price).

Demand for the Trigger Payment shall be given by notice in
accordance with the provisions of Section 17 hereof.  The Trigger
Payment shall be paid to OPTION HOLDER by OPTION GRANTOR on the
Payment Date (as defined herein), by wire transfer of immediately
available funds to an account to be designated in writing by
OPTION HOLDER not less than two business days before the Payment
Date.

          (b)  Payment Date.  For purposes of this Section 5,

Agreement as a result of the occurrence of the Trigger Event
referred to in subsection (a) of this Section 5.

          (c)  Certain Conditions.  OPTION GRANTOR shall have no
obligation to pay the Trigger Payment if OPTION HOLDER is in
material breach of any of its representations or warranties, or
in material breach of any of its covenants or agreements,
contained in this Agreement or in the Merger Agreement.

          6.   REPRESENTATIONS AND WARRANTIES OF OPTION GRANTOR.

                    license (any of the foregoing in effect on
                    the date hereof being referred to as a
                    "Material Contract") of OPTION GRANTOR or its
                    subsidiaries or to which any of them is a
                    party, or

             (iii)  any judgment, order, decree, statute, law,
                    ordinance, rule or regulation applicable to
                    OPTION GRANTOR or its properties or assets,
                    which Violation, in the case of each clauses
                    (ii) and (iii), could reasonably be expected
                    to have an OPTION GRANTOR Material Adverse
                    Effect (except that no representation or
                    warranty is given concerning any Violation of
                    a Material Contract with respect to the
                    repurchase of OPTION GRANTOR Shares pursuant
                    to Section 8(a));

          (f)  except as described in Section 5.4(c) of the IES
Disclosure Schedule to the Merger Agreement or Section 1 or 3
hereof, the execution and delivery of this Agreement by OPTION
GRANTOR does not, and the performance of this Agreement by OPTION
GRANTOR will not, require any consent, approval, authorization or
permit of, filing with or notification to, any Governmental
Authority;

          (g)  none of OPTION GRANTOR, any of its affiliates or
anyone acting on its or their behalf, has issued, sold or offered
any security of OPTION GRANTOR to any person under circumstances
that would cause the issuance and sale of OPTION GRANTOR Shares,
as contemplated by this Agreement, to be subject to the
registration requirements of the Securities Act as in effect on
the date hereof, and, assuming the representations and warranties
of OPTION HOLDER contained in Section 7(g) are true and correct,
the issuance, sale and delivery of the OPTION GRANTOR Shares
hereunder would be exempt from the registration and prospectus
delivery requirements of the Securities Act, as in effect on the
date hereof (and OPTION GRANTOR shall not take any action which
would cause the issuance, sale, and delivery of OPTION GRANTOR
Shares hereunder not to be exempt from such requirements); and

          (h)  any OPTION HOLDER Shares acquired pursuant to this
Agreement will be acquired for OPTION GRANTOR's own account, for
investment purposes only, and will not be acquired by OPTION
GRANTOR with a view to the public distribution thereof in
violation of any applicable provision of the Securities Act.

          7.   REPRESENTATIONS AND WARRANTIES OF OPTION HOLDER. 
OPTION HOLDER represents and warrants to OPTION GRANTOR that

          (a)  Except as set forth in Schedule 6.4(a) of the

except as may be limited by applicable bankruptcy, insolvency,
reorganization, or other similar laws affecting the enforcement
of creditors' rights generally, and except that the availability
of equitable remedies, including specific performance, may be

hereto, OPTION HOLDER will have taken all necessary corporate
action to authorize for issuance and to permit it to issue such
OPTION HOLDER Shares, all of which, upon their issuance and
delivery in accordance with the terms of this Agreement, will be
duly authorized, validly issued, fully paid and nonassessable;

          (d)  upon any delivery of such OPTION HOLDER Shares to
OPTION GRANTOR in consideration of the purchase of OPTION GRANTOR
Shares pursuant hereto, OPTION GRANTOR will acquire the OPTION
HOLDER Shares free and clear of all claims, liens, charges,
encumbrances and security interests of any nature whatsoever;

          (e)  except as described in Section 6.4(b) of the
Interstate Disclosure Schedule to the Merger Agreement, the
execution and delivery of this Agreement by OPTION HOLDER does
not, and the consummation by OPTION HOLDER of the transactions
contemplated hereby will not, violate, conflict with, or result
in the breach of any provision of, or constitute a default (with
or without notice or a lapse of time, or both) under, or result
in any Violation by OPTION HOLDER or any of its Subsidiaries,
pursuant to

               (i)  any provision of the Articles of
                    Incorporation or Bylaws of OPTION HOLDER,

               (ii) any Material Contract of OPTION HOLDER or any
                    of its subsidiaries or to which any of them
                    is a party, or

             (iii)  any judgment, order, decree, statute, law,
                    ordinance, rule or regulation applicable to
                    OPTION HOLDER or its properties or assets,
                    which Violation, in the case of each of
                    clauses (ii) or (iii), would have an OPTION
                    HOLDER Material Adverse Effect;

          (f)  except as described in Section 6.4(c) of the
Interstate Disclosure Schedule to the Merger Agreement or Section
1 or 3 hereof, the execution and delivery of this Agreement by
OPTION HOLDER does not, and the consummation by OPTION HOLDER of
the transactions contemplated hereby will not, require any
consent, approval, authorization or permit of, filing with or
notification to, any Governmental Authority; and

          (g)  any OPTION GRANTOR Shares acquired upon exercise
of the OPTION GRANTOR Option will be acquired for OPTION HOLDER's
own account, for investment purposes only and will not be, and
the OPTION GRANTOR Option is not being, acquired by OPTION HOLDER
with a view to the public distribution thereof, in violation of
any applicable provision of the Securities Act.

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

               (i)  (A)  The difference between the "Market/Offer
     Price" (as defined below) for shares of OPTION GRANTOR
     Common Stock as of the date OPTION HOLDER gives notice of
     its intent to exercise its rights under this Section 8 and
     the Exercise Price, multiplied by the number of OPTION
     GRANTOR Shares purchasable pursuant to the OPTION GRANTOR
     Option (or portion thereof with respect to which OPTION
     HOLDER is exercising its rights under this Section 8), but
     only if the Market/Offer Price is greater than the Exercise
     Price.

                    (B)  for purposes of this Agreement,
     "Market/Offer Price") shall mean, as of any date, the higher
     of (I) the price per share offered as of such date pursuant
     to any tender or exchange offer or other offer with respect
     to a Business Combination involving OPTION GRANTOR as the
     Target Party which was made prior to such date and not
     terminated or withdrawn as of such date and (II) the Fair
     Market Value of OPTION GRANTOR Common Stock as of such date.

          (ii) (A)  the product of (I) the sum of (a) the
     Exercise Price paid by OPTION HOLDER per OPTION GRANTOR
     Share acquired pursuant to the OPTION GRANTOR Option, and
     (b) the difference between the "Offer Price" (as defined
     below) and the Exercise Price, but only if the offer Price
     is greater that the Exercise Price, and (II) the number of
     OPTION GRANTOR Shares so to be repurchased pursuant to this
     Section 8.

                    (B)  For purposes of this clause (ii), the
     "Offer Price" shall be the highest price per share offered
     pursuant to a tender or exchange offer or other Business
     Combination offer involving OPTION GRANTOR as the Target
     Party during the Repurchase Period prior to the delivery by
     OPTION HOLDER of a notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.

          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii)  the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
this Section 11, the parties agree

               (i)  to indemnify each other and the underwriters
     in the customary manner,

               (ii) to enter into an underwriting agreement in
     form and substance customary for transactions of such type
     with the Manager and the other underwriters participating in
     such offering, and

               (iii)  to take all further actions which shall be
     reasonably necessary to effect such registration and sale
     (including if the Manager deems it necessary, participating
     in road-show presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,
which shall remain in full force and effect.

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among Interstate Power Company, a
corporation organized under the laws of the State of Delaware
("OPTION GRANTOR" or the "Company") and WPL Holdings, Inc., a
corporation organized under the laws of the State of Wisconsin
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, IES Industries
Inc., a corporation organized under the laws of the State of Iowa
("IES"), and AMW Acquisition, Inc., a wholly-owned subsidiary of
OPTION HOLDER organized under the laws of the State of Delaware
("AMW"), are entering into an Agreement and Plan of Merger, dated
as of November 10, 1995, (the "Merger Agreement"), which
provides, inter alia, upon the terms and subject to the
conditions thereof, for the merger of IES with and into OPTION
HOLDER in accordance with the laws of the States of Wisconsin and
Iowa (the "IES Merger"), and the merger of AMW with and into
OPTION GRANTOR in accordance with the laws of the State of
Delaware (the "Interstate Merger", and together with the IES
Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and IES are entering
into certain stock option agreements dated as of the date hereof,
of which this Agreement is one, whereby the parties hereto grant
each other an option with respect to certain shares of each
other's common stock on the terms and subject to the conditions
set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
6.4(c) of the Interstate Disclosure Schedule to the Merger
Agreement and by OPTION HOLDER as set forth in Section 4.4(c) of
the WPL Disclosure Schedule to the Merger Agreement, OPTION
GRANTOR hereby grants OPTION HOLDER an irrevocable option (the
"OPTION GRANTOR Option") to purchase up to that number of shares,
subject to adjustment as provided in Section 12 (the "OPTION
GRANTOR Shares"), of common stock, par value $3.50 per share, of
OPTION GRANTOR (the "OPTION GRANTOR Common Stock") equal to a
percentage (the "Option Shares Percentage"), which Option Shares
Percentage is equal to the OPTION HOLDER's Participation
Percentage as defined below in subsection (e), of 1,903,293
shares of OPTION GRANTOR Common Stock (being 19.9% of the number
of shares of OPTION GRANTOR Common Stock issued and outstanding
as of November 10, 1995, the "Initial Number") in the manner set
forth below, at a price (the "Exercise Price") per OPTION GRANTOR
Share of $28.9375 (which is equal to the Fair Market Value (as
defined below) of a OPTION GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, $.01 par value, of OPTION HOLDER ("OPTION
     HOLDER Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it
     wishes to purchase.

               (iii)     Upon the giving by OPTION HOLDER to
     OPTION GRANTOR of the Exercise Notice and the tender of the
     applicable aggregate Exercise Price, OPTION HOLDER, to the
     extent permitted by law and OPTION GRANTOR's organizational
     documents, and provided that the conditions to OPTION
     GRANTOR's obligation to issue the OPTION GRANTOR Shares to
     OPTION HOLDER hereunder set forth in Section 3 have been
     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such
     exercise, notwithstanding that the stock transfer books of
     OPTION GRANTOR shall then be closed or that certificates
     representing such OPTION GRANTOR Shares shall not then be
     actually delivered to OPTION HOLDER.

               (iv) Each closing of a purchase of OPTION GRANTOR
     Shares (a "Closing") shall occur at a place, on a date, and
     at a time designated by OPTION HOLDER in an Exercise Notice
     delivered at least two business days prior to the date of
     the Closing.

          (c)  The OPTION GRANTOR Option shall terminate upon the
earliest to occur of:

               (i)  the Effective Time of the Merger;

               (ii) the termination of the Merger Agreement
     pursuant to Section 10.1 thereof, other than under
     circumstances which also constitute a Trigger Event under
     this Agreement; 

               (iii)     180 days following any termination of
     the Merger Agreement upon or during the continuance of a
     Trigger Event (or if, at the expiration of such 180 day
     period, the OPTION GRANTOR Option cannot be exercised by
     reason of any applicable judgment, decree, order, law or
     regulation, ten business days after such impediment to
     exercise shall have been removed or shall have become final
     and not subject to appeal, but in no event under this clause
     (iii) later than May 10, 1998); and

               (iv) payment by OPTION GRANTOR of the Trigger
     Payment set forth in Section 5 of this Agreement to OPTION
     HOLDER.

          (d)  Notwithstanding the foregoing, the OPTION GRANTOR
Option may not be exercised if (i) OPTION HOLDER is in material
breach of any of its representations or warranties, or in
material breach of any of its covenants or agreements, contained
in this Agreement or in the Merger Agreement, or (ii) a Trigger
Payment has been paid pursuant to Section 5 of this Agreement or
demand therefor has been made and not withdrawn.

          3.   CONDITIONS TO CLOSING.  The obligation of OPTION
GRANTOR to issue the OPTION GRANTOR Shares to OPTION HOLDER
hereunder is subject to the conditions that

          (a)  all waiting periods, if any, under the HSR Act
applicable to the issuance and acquisition of the OPTION GRANTOR
Shares hereunder shall have expired or have been terminated;

          (b)  the OPTION GRANTOR Shares, and any OPTION HOLDER
Shares which are issued in payment of the Exercise Price, shall
have been approved for listing on the NYSE subject only to
official notice of issuance;

          (c)  all consents, approvals, orders or authorizations
of, or registrations, declarations or filings with, any federal,
state or local administrative agency or commission or other
federal, state or local Governmental Authority, if any, required
in connection with the issuance by OPTION GRANTOR and the
acquisition by OPTION HOLDER of the OPTION GRANTOR Shares
hereunder shall have been obtained or made, including, without
limitation, the approval of the SEC under Sections 9 and 10 of
the Public Utility Holding Company Act of 1935, as amended (the
"1935 Act"), the approval of Iowa Utilities Board, the Public
Service Commission of Minnesota and the Illinois Commerce
Commission of the issuance of the OPTION GRANTOR Shares by OPTION
GRANTOR and, if applicable, the acquisition of OPTION GRANTOR
Shares by OPTION HOLDER, and the approval of the Public Service
Commission of Wisconsin of the acquisition of the OPTION GRANTOR
Shares by OPTION HOLDER and, if applicable, the acquisition by
OPTION GRANTOR of the OPTION HOLDER Shares constituting the
Exercise Price hereunder; and

          (d)  no preliminary or permanent injunction or other
order by any court of competent jurisdiction prohibiting or
otherwise restraining such issuance shall be in effect.

The condition set forth in paragraph (b) above may be waived by
OPTION GRANTOR, in the case of OPTION HOLDER Shares, and by
OPTION HOLDER, in the case of OPTION GRANTOR Shares, in the sole
discretion of the waiving party.

          4.   CLOSING.  At any Closing,

          (a)  OPTION GRANTOR shall deliver to OPTION HOLDER or
its designee a single certificate in definitive form representing
the number of OPTION GRANTOR Shares designated by OPTION HOLDER
in its Exercise Notice, such certificate to be registered in the
name of OPTION HOLDER and to bear the legend set forth in Section
13; and

          (b)  OPTION HOLDER shall deliver to OPTION GRANTOR the
aggregate price for the OPTION GRANTOR Shares so designated and
being purchased by

               (i)  wire transfer of immediately available funds
     or certified check or bank check, or

               (ii) subject to the condition in Section 1(b)(ii),
     delivery of a certificate or certificates representing the
     number of OPTION HOLDER Shares being issued by OPTION HOLDER
     in consideration thereof, determined in accordance with
     Section 4(c).

          (c)  In the event that OPTION HOLDER issues OPTION
HOLDER Shares to OPTION GRANTOR in consideration of OPTION
GRANTOR Shares pursuant to Section 4(b)(ii), the number of OPTION
HOLDER Shares to be so issued shall be equal to the quotient
obtained by dividing:

               (i)  the product of (x) the number of OPTION
     GRANTOR Shares with respect to which the OPTION GRANTOR
     Option is being exercised and (y) the Exercise Price, by

               (ii) the Fair Market Value of the OPTION HOLDER
     Shares as of the date immediately preceding the date the
     Exercise Notice is delivered to OPTION GRANTOR.

          (d)  OPTION GRANTOR shall pay all expenses, and any and

payable in connection with the preparation, issue and delivery of
stock certificates under this Section 4.

          5.   TRIGGER PAYMENT.

          (a)  Trigger Payment.  Subject to the provisions of
Section 10.3(e) of the Merger Agreement, if a Trigger Event shall
have occurred and any regulatory approval or order required for
the issuance by OPTION GRANTOR, or the acquisition by OPTION
HOLDER, of the OPTION GRANTOR Option pursuant to Section 1 hereof
shall not have been obtained, OPTION HOLDER shall have the right
to receive, and OPTION GRANTOR shall pay to OPTION HOLDER, an
amount (the "Trigger Payment") equal to the product of

     (i)  the maximum number of OPTION GRANTOR Shares that would
     have been subject to purchase by OPTION HOLDER upon exercise
     of the OPTION GRANTOR Option pursuant to Sections 1 and 2
     hereof if all such regulatory approvals or orders had been
     obtained, and

     (ii)  the difference between (A) the Market/Offer Price (as
     defined herein), determined as of the date on which notice
     of demand for the Trigger Payment is given by OPTION HOLDER,
     and (B) the Exercise Price (but only if such Market/Offer
     Price is higher than such Exercise Price).

Demand for the Trigger Payment shall be given by notice in
accordance with the provisions of Section 17 hereof.  The Trigger
Payment shall be paid to OPTION HOLDER by OPTION GRANTOR on the
Payment Date (as defined herein), by wire transfer of immediately
available funds to an account to be designated in writing by
OPTION HOLDER not less than two business days before the Payment
Date.

          (b)  Payment Date.  For purposes of this Section 5,
"Payment Date" means the date on which termination fees are
required to be paid by OPTION GRANTOR to OPTION HOLDER under
Sections 10.3(a) or 10.3(b), as the case may be, of the Merger
Agreement as a result of the occurrence of the Trigger Event
referred to in subsection (a) of this Section 5.

          (c)  Certain Conditions.  OPTION GRANTOR shall have no
obligation to pay the Trigger Payment if OPTION HOLDER is in
material breach of any of its representations or warranties, or
in material breach of any of its covenants or agreements,
contained in this Agreement or in the Merger Agreement.

          6.   REPRESENTATIONS AND WARRANTIES OF OPTION GRANTOR. 
OPTION GRANTOR represents and warrants to OPTION HOLDER that

          (a)  Except as set forth in Section 6.4(a) of the
Interstate Disclosure Schedule to the Merger Agreement, OPTION
GRANTOR has the corporate power and authority to enter into this
Agreement and to carry out its obligations hereunder, subject in
the case of the repurchase of the OPTION GRANTOR Shares pursuant
to Section 8(a) to applicable law and the provisions of OPTION
GRANTOR's Articles of Incorporation, as amended (the "OPTION
GRANTOR Articles");

          (b)  this Agreement has been duly and validly executed
and delivered by OPTION GRANTOR, and, assuming the due
authorization, execution and delivery hereof by OPTION HOLDER and
the receipt of all required regulatory approvals, constitutes a
valid and binding obligation of OPTION GRANTOR, enforceable
against OPTION GRANTOR in accordance with its terms, except as
may be limited by applicable bankruptcy, insolvency,
reorganization or other similar laws affecting the enforcement of
creditors' rights generally, and except that the availability of
equitable remedies, including specific performance, may be
subject to the discretion of any court before which any
proceeding therefor may be brought;

          (c)  OPTION GRANTOR has taken all necessary corporate
action to authorize and reserve for issuance and to permit it to
issue, upon exercise of the OPTION GRANTOR Option, and at all
times from the date hereof through the expiration of the OPTION
GRANTOR Option will have reserved, the Initial Number of
authorized and unissued OPTION GRANTOR Shares, such amount being
subject to adjustment as provided in Section 12, all of which,
upon their issuance and delivery in accordance with the terms of
this Agreement, will be duly authorized, validly issued, fully
paid and nonassessable;

          (d)  upon delivery of the OPTION GRANTOR Shares to
OPTION HOLDER upon the exercise of the OPTION GRANTOR Option,
OPTION HOLDER will acquire the OPTION GRANTOR Shares free and
clear of all claims, liens, charges, encumbrances and security
interests of any nature whatsoever;

          (e)  except as described in Section 6.4(b) of the
Interstate Disclosure Schedule to the Merger Agreement, the
execution and delivery of this Agreement by OPTION GRANTOR does
not, and, subject to compliance with applicable law and the
OPTION GRANTOR Articles with respect to the repurchase of the
OPTION GRANTOR Shares pursuant to Section 8(a), the consummation
by OPTION GRANTOR of the transactions contemplated hereby will
not, violate, conflict with, or result in a breach of any
provision of, or constitute a default (with or without notice or
a lapse of time, or both) under, or result in the termination of,
or accelerate the performance required by, or result in a right
of termination, cancellation, or acceleration of any obligation
or the loss of a material benefit under, or the creation of a
lien, pledge, security interest or other encumbrance on assets
(any such conflict, violation, default, right of termination,
cancellation, acceleration, loss or creation, hereinafter a
"Violation") of OPTION GRANTOR or any of its Subsidiaries,
pursuant to

          (i)  any provision of the OPTION GRANTOR Articles or
               the Bylaws of OPTION GRANTOR,

          (ii) any provisions of any material loan or credit
               agreement, note, mortgage, indenture, lease,
               benefit plan or other agreement, obligation,
               instrument, permit, concession, franchise or
               license (any of the foregoing in effect on the
               date hereof being referred to as a "Material
               Contract") of OPTION GRANTOR or its subsidiaries
               or to which any of them is a party, or

        (iii)  any judgment, order, decree, statute, law,
               ordinance, rule or regulation applicable to OPTION
               GRANTOR or its properties or assets,

which Violation, in the case of each clauses (ii) and (iii),
could reasonably be expected to have an OPTION GRANTOR Material
Adverse Effect (except that no representation or warranty is
given concerning any Violation of a Material Contract with
respect to the repurchase of OPTION GRANTOR Shares pursuant to
Section 8(a));

          (f)  except as described in Section 6.4(c) of the
Interstate Disclosure Schedule to the Merger Agreement or Section
1 or 3 hereof, the execution and delivery of this Agreement by
OPTION GRANTOR does not, and the performance of this Agreement by
OPTION GRANTOR will not, require any consent, approval,
authorization or permit of, filing with or notification to, any
Governmental Authority;

          (g)  none of OPTION GRANTOR, any of its affiliates or
anyone acting on its or their behalf, has issued, sold or offered
any security of OPTION GRANTOR to any person under circumstances
that would cause the issuance and sale of OPTION GRANTOR Shares,
as contemplated by this Agreement, to be subject to the
registration requirements of the Securities Act as in effect on
the date hereof, and, assuming the representations and warranties
of OPTION HOLDER contained in Section 7(g) are true and correct,
the issuance, sale and delivery of the OPTION GRANTOR Shares
hereunder would be exempt from the registration and prospectus
delivery requirements of the Securities Act, as in effect on the
date hereof (and OPTION GRANTOR shall not take any action which
would cause the issuance, sale, and delivery of OPTION GRANTOR
Shares hereunder not to be exempt from such requirements); and

          (h)  any OPTION HOLDER Shares acquired pursuant to this
Agreement will be acquired for OPTION GRANTOR's own account, for
investment purposes only, and will not be acquired by OPTION
GRANTOR with a view to the public distribution thereof in
violation of any applicable provision of the Securities Act.

        (iii)  any judgment, order, decree, statute, law,
               ordinance, rule or regulation applicable to OPTION

               Adverse Effect;

          (f)  except as described in Section 4.4(c) of the WPL

with a view to the public distribution thereof, in violation of
any applicable provision of the Securities Act.

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

          (i)  (A)  The difference between the "Market/Offer
               Price" (as defined below) for shares of OPTION
               GRANTOR Common Stock as of the date OPTION HOLDER
               gives notice of its intent to exercise its rights
               under this Section 8 and the Exercise Price,
               multiplied by the number of OPTION GRANTOR Shares
               purchasable pursuant to the OPTION GRANTOR Option
               (or portion thereof with respect to which OPTION
               HOLDER is exercising its rights under this Section
               8), but only if the Market/Offer Price is greater
               than the Exercise Price.

               (B)  for purposes of this Agreement, "Market/Offer
               Price") shall mean, as of any date, the higher of
               (I) the price per share offered as of such date
               pursuant to any tender or exchange offer or other
               offer with respect to a Business Combination
               involving OPTION GRANTOR as the Target Party which
               was made prior to such date and not terminated or
               withdrawn as of such date and (II) the Fair Market
               Value of OPTION GRANTOR Common Stock as of such
               date.

          (ii) (A)  the product of (I) the sum of (a) the
               Exercise Price paid by OPTION HOLDER per OPTION
               GRANTOR Share acquired pursuant to the OPTION
               GRANTOR Option, and (b) the difference between the
               "Offer Price" (as defined below) and the Exercise
               Price, but only if the offer Price is greater that
               the Exercise Price, and (II) the number of OPTION
               GRANTOR Shares so to be repurchased pursuant to
               this Section 8.

               (B)  For purposes of this clause (ii), the "Offer
Price" shall be the highest price per share offered pursuant to a
tender or exchange offer or other Business Combination offer
involving OPTION GRANTOR as the Target Party during the
Repurchase Period prior to the delivery by OPTION HOLDER of a
notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.

          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii)  the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
this Section 11, the parties agree

          (i)  to indemnify each other and the underwriters in
               the customary manner,

          (ii) to enter into an underwriting agreement in form
               and substance customary for transactions of such
               type with the Manager and the other underwriters
               participating in such offering, and

         (iii) to take all further actions which shall be
               reasonably necessary to effect such registration
               and sale (including if the Manager deems it
               necessary, participating in road-show
               presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,
which shall remain in full force and effect.

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to
specific performance of such provision or part hereof or to any
other remedy, including but not limited to money damages, for
breach hereof or of any other provision of this Agreement or part
hereof as the result of such holding or order.

          17.  NOTICES.  All notices and other communications
hereunder shall be in writing and shall be deemed given if (a)
delivered personally, or (b) if sent by overnight courier service

            OPTION GRANTOR/OPTION HOLDER STOCK OPTION
                  AND TRIGGER PAYMENT AGREEMENT


          This STOCK OPTION AGREEMENT, dated as of November 10,
1995 (the "Agreement") by and among Interstate Power Company, a
corporation organized under the laws of the State of Delaware
("OPTION GRANTOR" or the "Company") and IES Industries Inc., a
corporation organized under the laws of the State of Iowa
("OPTION HOLDER").

                 W I T N E S S E T H   T H A T:

          WHEREAS, concurrently with the execution and delivery
of this Agreement, OPTION GRANTOR, OPTION HOLDER, WPL Holdings,
Inc., a corporation organized under the laws of the State of
Wisconsin ("WPL"), and AMW Acquisition, Inc., a wholly-owned
subsidiary of WPL organized under the laws of the State of
Delaware ("AMW"), are entering into an Agreement and Plan of
Merger, dated as of November 10, 1995, (the "Merger Agreement"),
which provides, inter alia, upon the terms and subject to the
conditions thereof, for the merger of OPTION HOLDER with and into
WPL in accordance with the laws of the States of Wisconsin and
Iowa (the "IES Merger"), and the merger of AMW with and into
OPTION GRANTOR in accordance with the laws of the State of
Delaware (the "Interstate Merger, and together with the IES
Merger, the "Merger");

          WHEREAS, in connection with the execution of the Merger
Agreement, OPTION GRANTOR, OPTION HOLDER and WPL are entering
into certain stock option agreements dated as of the date hereof,
of which this Agreement is one, whereby the parties hereto grant
each other an option with respect to certain shares of each
other's common stock on the terms and subject to the conditions
set forth therein (the "Stock Option Agreements"); and

          WHEREAS, as a condition to OPTION HOLDER's willingness
to enter into the Merger Agreement, OPTION HOLDER has requested
that OPTION GRANTOR agree, and OPTION GRANTOR has so agreed, to
grant to OPTION HOLDER an option with respect to certain shares
of OPTION GRANTOR's common stock, on the terms and subject to the
conditions set forth herein;

          NOW, THEREFORE, to induce OPTION HOLDER to enter into
the Merger Agreement and certain of the Stock Option Agreements,
and in consideration of the representations, warranties,
covenants and agreements contained herein, in the Merger
Agreement and in the Stock Option Agreements to which OPTION
GRANTOR and OPTION HOLDER are parties, the parties hereto,
intending to be legally bound, hereby agree as follows:

          1.   GRANT OF OPTION.

          (a)  Subject to the receipt of all regulatory approvals
and orders required by OPTION GRANTOR as set forth in Section
6.4(c) of the Interstate Disclosure Schedule to the Merger
Agreement and by OPTION HOLDER as set forth in Section 5.4(c) of
the IES Disclosure Schedule to the Merger Agreement, OPTION
GRANTOR hereby grants OPTION HOLDER an irrevocable option (the
"OPTION GRANTOR Option") to purchase up to that number of shares,
subject to adjustment as provided in Section 12 (the "OPTION
GRANTOR Shares"), of common stock, par value $3.50 per share, of
OPTION GRANTOR (the "OPTION GRANTOR Common Stock") equal to a
percentage (the "Option Shares Percentage"), which Option Shares
Percentage is equal to the OPTION HOLDER's Participation
Percentage as defined below in subsection (e), of 1,903,293
shares of OPTION GRANTOR Common Stock (being 19.9% of the number
of shares of OPTION GRANTOR Common Stock issued and outstanding
as of November 10, 1995, the "Initial Number") in the manner set
forth below, at a price (the "Exercise Price") per OPTION GRANTOR
Share of $28.9375 (which is equal to the Fair Market Value (as
defined below) of a OPTION GRANTOR Share as of the date hereof).

          (b)  The Exercise Price shall be payable, at OPTION
HOLDER's option, as follows:

               (i)  in cash, or

               (ii) subject to the receipt of all approvals of
     any Governmental Authority required for OPTION GRANTOR to
     acquire, and OPTION HOLDER to issue, the OPTION HOLDER
     Shares (as defined below) from OPTION HOLDER, in shares of
     common stock, no par value, of OPTION HOLDER ("OPTION HOLDER
     Shares"),

in either case in accordance with Section 4 hereof.

          (c)  Notwithstanding the foregoing, in no event shall
the number of OPTION GRANTOR Shares for which the OPTION GRANTOR
Option is exercisable exceed the product of the Option Shares
Percentage and the Initial Number, subject to adjustment as
provided in Section 12.

          (d)  As used herein, the "Fair Market Value" of any
share shall be the average of the daily closing sales price for
such share on the New York Stock Exchange (the "NYSE") during the
ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such Fair Market Value is to be determined.

          (e)  For purposes of this Agreement the term
"Participation Percentage" shall have the same meaning as in
Section 10.3(f)(i) of the Merger Agreement, except that the
numerator and denominator shall be calculated based on the number
of shares of WPL Common Stock which would be issuable (or, in the
case of WPL, retained by its shareholders) on a fully diluted
basis had the Effective Time occurred as of the date on which the
Exercise Notice is delivered under Section 2 hereof or the date
on which demand for the Trigger Payment (as defined herein) is
given under Section 5 hereof, as the case may be.  Other
capitalized terms used herein but not defined herein shall have
the meanings set forth in the Merger Agreement.

          2.   EXERCISE OF OPTION.

          (a)  The OPTION GRANTOR Option may be exercised by
OPTION HOLDER, in whole or in part, at any time or from time to
time after the Merger Agreement becomes terminable by OPTION
HOLDER under circumstances which could entitle OPTION HOLDER to a
termination fee under Section 10.3(a) of the Merger Agreement
(provided that the events specified in Section 10.3(a)(ii)(A) of
the Merger Agreement shall have occurred, although the events
specified in Section 10.3(a)(ii)(B) thereof need not have
occurred), or Section 10.3(b) of the Merger Agreement (regardless
of whether the Merger Agreement is actually terminated or whether
there occurs a closing of any Business Combination involving a
Target Party or a closing by which a Target Party becomes a
Subsidiary), any such event by which the Merger Agreement becomes
so terminable by OPTION HOLDER being referred to herein as a
"Trigger Event").

          (b)  (i)  OPTION GRANTOR shall notify OPTION HOLDER
     promptly in writing of the occurrence of any Trigger Event,
     it being understood that the giving of such notice by OPTION
     GRANTOR shall not be a condition to the right of OPTION
     HOLDER to exercise the OPTION GRANTOR Option.

               (ii) In the event OPTION HOLDER wishes to exercise
     the OPTION GRANTOR Option, OPTION HOLDER shall deliver to
     OPTION GRANTOR written notice (an "Exercise Notice")
     specifying the total number of OPTION GRANTOR Shares it
     wishes to purchase.

               (iii)     Upon the giving by OPTION HOLDER to
     OPTION GRANTOR of the Exercise Notice and the tender of the
     applicable aggregate Exercise Price, OPTION HOLDER, to the
     extent permitted by law and OPTION GRANTOR's organizational
     documents, and provided that the conditions to OPTION
     GRANTOR's obligation to issue the OPTION GRANTOR Shares to
     OPTION HOLDER hereunder set forth in Section 3 have been
     satisfied or waived, shall be deemed to be the holder of
     record of the OPTION GRANTOR Shares issuable upon such
     exercise, notwithstanding that the stock transfer books of
     OPTION GRANTOR shall then be closed or that certificates
     representing such OPTION GRANTOR Shares shall not then be
     actually delivered to OPTION HOLDER.

               (iv) Each closing of a purchase of OPTION GRANTOR
     Shares (a "Closing") shall occur at a place, on a date, and
     at a time designated by OPTION HOLDER in an Exercise Notice
     delivered at least two business days prior to the date of
     the Closing.

          (c)  The OPTION GRANTOR Option shall terminate upon the
earliest to occur of:

               (i)   the Effective Time of the Merger;

               (ii)  the termination of the Merger Agreement
     pursuant to Section 10.1 thereof, other than under
     circumstances which also constitute a Trigger Event under
     this Agreement; 

               (iii) 180 days following any termination of the
     Merger Agreement upon or during the continuance of a Trigger
     Event (or if, at the expiration of such 180 day period, the
     OPTION GRANTOR Option cannot be exercised by reason of any
     applicable judgment, decree, order, law or regulation, ten
     business days after such impediment to exercise shall have
     been removed or shall have become final and not subject to
     appeal, but in no event under this clause (iii) later than
     May 10, 1998); and

               (iv) payment by OPTION GRANTOR of the Trigger
     Payment set forth in Section 5 of this Agreement to OPTION
     HOLDER.

          (d)  Notwithstanding the foregoing, the OPTION GRANTOR
Option may not be exercised if (i) OPTION HOLDER is in material
breach of any of its representations or warranties, or in
material breach of any of its covenants or agreements, contained
in this Agreement or in the Merger Agreement, or (ii) a Trigger
Payment has been paid pursuant to Section 5 of this Agreement or
demand therefor has been made and not withdrawn.

          3.   CONDITIONS TO CLOSING.  The obligation of OPTION
GRANTOR to issue the OPTION GRANTOR Shares to OPTION HOLDER
hereunder is subject to the conditions that

          (a)  all waiting periods, if any, under the HSR Act
applicable to the issuance and acquisition of the OPTION GRANTOR
Shares hereunder shall have expired or have been terminated;

          (b)  the OPTION GRANTOR Shares, and any OPTION HOLDER
Shares which are issued in payment of the Exercise Price, shall
have been approved for listing on the NYSE subject only to
official notice of issuance;

          (c)  all consents, approvals, orders or authorizations
of, or registrations, declarations or filings with, any federal,
state or local administrative agency or commission or other
federal, state or local Governmental Authority, if any, required
in connection with the issuance by OPTION GRANTOR and the
acquisition by OPTION HOLDER of the OPTION GRANTOR Shares

Shares by OPTION HOLDER, and the approval of the Iowa Utilities
Board of the acquisition of the OPTION GRANTOR Shares by OPTION
HOLDER and, if applicable, the acquisition by OPTION GRANTOR of
the OPTION HOLDER Shares constituting the Exercise Price
hereunder; and

          (d)  no preliminary or permanent injunction or other
order by any court of competent jurisdiction prohibiting or
otherwise restraining such issuance shall be in effect.

The condition set forth in paragraph (b) above may be waived by
OPTION GRANTOR, in the case of OPTION HOLDER Shares, and by
OPTION HOLDER, in the case of OPTION GRANTOR Shares, in the sole
discretion of the waiving party.

          4.   CLOSING.  At any Closing,

          (a)  OPTION GRANTOR shall deliver to OPTION HOLDER or
its designee a single certificate in definitive form representing
the number of OPTION GRANTOR Shares designated by OPTION HOLDER
in its Exercise Notice, such certificate to be registered in the
name of OPTION HOLDER and to bear the legend set forth in Section
13; and

          (b)  OPTION HOLDER shall deliver to OPTION GRANTOR the
aggregate price for the OPTION GRANTOR Shares so designated and
being purchased by

               (i)  wire transfer of immediately available funds
     or certified check or bank check, or

               (ii) subject to the condition in Section 1(b)(ii),
     delivery of a certificate or certificates representing the
     number of OPTION HOLDER Shares being issued by OPTION HOLDER
     in consideration thereof, determined in accordance with
     Section 4(c).

          (c)  In the event that OPTION HOLDER issues OPTION
HOLDER Shares to OPTION GRANTOR in consideration of OPTION
GRANTOR Shares pursuant to Section 4(b)(ii), the number of OPTION
HOLDER Shares to be so issued shall be equal to the quotient
obtained by dividing:

               (i)  the product of (x) the number of OPTION
     GRANTOR Shares with respect to which the OPTION GRANTOR
     Option is being exercised and (y) the Exercise Price, by

               (ii) the Fair Market Value of the OPTION HOLDER

HOLDER, of the OPTION GRANTOR Option pursuant to Section 1 hereof
shall not have been obtained, OPTION HOLDER shall have the right
to receive, and OPTION GRANTOR shall pay to OPTION HOLDER, an
amount (the "Trigger Payment") equal to the product of

     (i)  the maximum number of OPTION GRANTOR Shares that would
     have been subject to purchase by OPTION HOLDER upon exercise
     of the OPTION GRANTOR Option pursuant to Sections 1 and 2
     hereof if all such regulatory approvals or orders had been
     obtained, and

     (ii)  the difference between (A) the Market/Offer Price (as
     defined herein), determined as of the date on which notice
     of demand for the Trigger Payment is given by OPTION HOLDER,
     and (B) the Exercise Price (but only if such Market/Offer
     Price is higher than such Exercise Price).

Demand for the Trigger Payment shall be given by notice in
accordance with the provisions of Section 17 hereof.  The Trigger
Payment shall be paid to OPTION HOLDER by OPTION GRANTOR on the
Payment Date (as defined herein), by wire transfer of immediately
available funds to an account to be designated in writing by
OPTION HOLDER not less than two business days before the Payment
Date.

          (b)  Payment Date.  For purposes of this Section 5,

Agreement as a result of the occurrence of the Trigger Event
referred to in subsection (a) of this Section 5.

          (c)  Certain Conditions.  OPTION GRANTOR shall have no
obligation to pay the Trigger Payment if OPTION HOLDER is in
material breach of any of its representations or warranties, or
in material breach of any of its covenants or agreements,
contained in this Agreement or in the Merger Agreement.

          6.   REPRESENTATIONS AND WARRANTIES OF OPTION GRANTOR.

          (b)  this Agreement has been duly and validly executed

creditors' rights generally, and except that the availability of
equitable remedies, including specific performance, may be
subject to the discretion of any court before which any
proceeding therefor may be brought;

          (c)  OPTION GRANTOR has taken all necessary corporate
action to authorize and reserve for issuance and to permit it to
issue, upon exercise of the OPTION GRANTOR Option, and at all
times from the date hereof through the expiration of the OPTION
GRANTOR Option will have reserved, the Initial Number of

subject to adjustment as provided in Section 12, all of which,
upon their issuance and delivery in accordance with the terms of
this Agreement, will be duly authorized, validly issued, fully
paid and nonassessable;

          (d)  upon delivery of the OPTION GRANTOR Shares to
OPTION HOLDER upon the exercise of the OPTION GRANTOR Option,
OPTION HOLDER will acquire the OPTION GRANTOR Shares free and
clear of all claims, liens, charges, encumbrances and security
interests of any nature whatsoever;

          (e)  except as described in Section 6.4(b) of the
Interstate Disclosure Schedule to the Merger Agreement, the

not, and, subject to compliance with applicable law and the
OPTION GRANTOR Articles with respect to the repurchase of the
OPTION GRANTOR Shares pursuant to Section 8(a), the consummation
by OPTION GRANTOR of the transactions contemplated hereby will
not, violate, conflict with, or result in a breach of any

of termination, cancellation, or acceleration of any obligation
or the loss of a material benefit under, or the creation of a
lien, pledge, security interest or other encumbrance on assets
(any such conflict, violation, default, right of termination,
cancellation, acceleration, loss or creation, hereinafter a
"Violation") of OPTION GRANTOR or any of its Subsidiaries,
pursuant to

            (i)     any provision of the OPTION GRANTOR Articles
          or the Bylaws of OPTION GRANTOR,

            (ii)    any provisions of any material loan or credit
          agreement, note, mortgage, indenture, lease, benefit
          plan or other agreement, obligation, instrument,

          ordinance, rule or regulation applicable to OPTION
          GRANTOR or its properties or assets,

which Violation, in the case of each clauses (ii) and (iii),
could reasonably be expected to have an OPTION GRANTOR Material
Adverse Effect (except that no representation or warranty is
given concerning any Violation of a Material Contract with
respect to the repurchase of OPTION GRANTOR Shares pursuant to
Section 8(a));

          (f)  except as described in Section 6.4(c) of the
Interstate Disclosure Schedule to the Merger Agreement or Section
1 or 3 hereof, the execution and delivery of this Agreement by
OPTION GRANTOR does not, and the performance of this Agreement by

          (g)  none of OPTION GRANTOR, any of its affiliates or
anyone acting on its or their behalf, has issued, sold or offered
any security of OPTION GRANTOR to any person under circumstances

registration requirements of the Securities Act as in effect on
the date hereof, and, assuming the representations and warranties
of OPTION HOLDER contained in Section 7(g) are true and correct,
the issuance, sale and delivery of the OPTION GRANTOR Shares
hereunder would be exempt from the registration and prospectus
delivery requirements of the Securities Act, as in effect on the

Shares hereunder not to be exempt from such requirements); and

          (h)  any OPTION HOLDER Shares acquired pursuant to this
Agreement will be acquired for OPTION GRANTOR's own account, for

          its subsidiaries or to which any of them is a party, or

          (iii) any judgment, order, decree, statute, law,
          ordinance, rule or regulation applicable to OPTION
          HOLDER or its properties or assets,

which Violation, in the case of each of clauses (ii) or (iii),
would have an OPTION HOLDER Material Adverse Effect;

          (f)  except as described in Section 5.4(c) of the IES
Disclosure Schedule to the Merger Agreement or Section 1 or 3
hereof, the execution and delivery of this Agreement by OPTION
HOLDER does not, and the consummation by OPTION HOLDER of the
transactions contemplated hereby will not, require any consent,
approval, authorization or permit of, filing with or notification
to, any Governmental Authority; and

          (g)  any OPTION GRANTOR Shares acquired upon exercise
of the OPTION GRANTOR Option will be acquired for OPTION HOLDER's
own account, for investment purposes only and will not be, and
the OPTION GRANTOR Option is not being, acquired by OPTION HOLDER
with a view to the public distribution thereof, in violation of
any applicable provision of the Securities Act.

          8.   CERTAIN REPURCHASES.

          (a)  OPTION HOLDER "PUT".  At the request of OPTION
HOLDER by written notice (x) at any time during which the OPTION
GRANTOR Option is exercisable pursuant to Section 2 (the
"Repurchase Period"), OPTION GRANTOR (or any successor entity
thereof) shall, if permitted by applicable law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material
Contracts, repurchase from OPTION HOLDER all or any portion of
the OPTION GRANTOR Option, at the price set forth in subparagraph
(i) below, or, (y) at any time prior to May 10, 1997 (provided
that such date shall be extended to May 10, 1998 under the
circumstances where the date after which either party may
terminate the Merger Agreement pursuant to Section 10.1(b) of the
Merger Agreement has been extended to May 10, 1998), OPTION
GRANTOR (or any successor entity thereof) shall, if permitted by
applicable law, the OPTION GRANTOR Articles and Bylaws and OPTION
GRANTOR's Material Contracts, repurchase from OPTION HOLDER all
or any portion of the OPTION GRANTOR Shares purchased by OPTION
HOLDER pursuant to the OPTION GRANTOR Option, at the price set
forth in subparagraph (ii) below:

          (i)  (A)  The difference between the "Market/Offer
     Price" (as defined below) for shares of OPTION GRANTOR
     Common Stock as of the date OPTION HOLDER gives notice of
     its intent to exercise its rights under this Section 8 and
     the Exercise Price, multiplied by the number of OPTION
     GRANTOR Shares purchasable pursuant to the OPTION GRANTOR
     Option (or portion thereof with respect to which OPTION
     HOLDER is exercising its rights under this Section 8), but
     only if the Market/Offer Price is greater than the Exercise
     Price.

               (B)  for purposes of this Agreement, "Market/Offer
     Price") shall mean, as of any date, the higher of (I) the
     price per share offered as of such date pursuant to any
     tender or exchange offer or other offer with respect to a
     Business Combination involving OPTION GRANTOR as the Target
     Party which was made prior to such date and not terminated
     or withdrawn as of such date and (II) the Fair Market Value
     of OPTION GRANTOR Common Stock as of such date.

          (ii) (A)  the product of (I) the sum of (a) the
     Exercise Price paid by OPTION HOLDER per OPTION GRANTOR
     Share acquired pursuant to the OPTION GRANTOR Option, and
     (b) the difference between the "Offer Price" (as defined
     below) and the Exercise Price, but only if the offer Price
     is greater that the Exercise Price, and (II) the number of
     OPTION GRANTOR Shares so to be repurchased pursuant to this
     Section 8.

               (B)  For purposes of this clause (ii), the "Offer
     Price" shall be the highest price per share offered pursuant
     to a tender or exchange offer or other Business Combination
     offer involving OPTION GRANTOR as the Target Party during
     the Repurchase Period prior to the delivery by OPTION HOLDER
     of a notice of repurchase.

          (b)  REDELIVERY OF OPTION HOLDER SHARES.  If OPTION
HOLDER shall have previously elected to purchase OPTION GRANTOR
Shares pursuant to the exercise of the OPTION GRANTOR Option by
the issuance and delivery of OPTION HOLDER Shares, then OPTION
GRANTOR shall, if so requested by OPTION HOLDER, in fulfillment
of its obligation pursuant to Section 8(a)(y) (that is, with
respect to the Exercise Price only and without limitation to its
obligation to pay additional consideration under clause (b) of
Section 8(a)(ii)(A)(I)), redeliver the certificates for such
OPTION HOLDER Shares to OPTION HOLDER, free and clear of all
liens, claims, charges and encumbrances of any kind or nature
whatsoever; provided, however, that if at any time less than all
of the OPTION GRANTOR Shares so purchased by OPTION HOLDER
pursuant to the OPTION GRANTOR Option are to be repurchased by
OPTION GRANTOR pursuant to Section 8(a)(y), then (i) OPTION
GRANTOR shall be obligated to redeliver to OPTION HOLDER the same
proportion of such OPTION HOLDER Shares as the number of OPTION
GRANTOR Shares that OPTION GRANTOR is then obligated to
repurchase bears to the number of OPTION GRANTOR Shares acquired
by OPTION HOLDER upon exercise of the OPTION GRANTOR Option and
(ii) OPTION HOLDER shall issue to OPTION GRANTOR new certificates
representing those OPTION HOLDER Shares which are not due to be
redelivered to OPTION HOLDER pursuant to this Section 8(b) to the
extent that excess OPTION HOLDER Shares are included in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.

          (c)  PAYMENT AND REDELIVERY OF OPTION GRANTOR OPTIONS
OR SHARES.  In the event OPTION HOLDER exercises its rights under
this Section 8, OPTION GRANTOR shall, within ten business days
thereafter, pay the required amount to OPTION HOLDER in
immediately available funds and OPTION HOLDER shall surrender to
OPTION GRANTOR the OPTION GRANTOR Option or the certificate or
certificates evidencing the OPTION GRANTOR Shares purchased by
OPTION HOLDER pursuant hereto, and OPTION HOLDER shall warrant
that it owns the OPTION GRANTOR Option or such shares and that
the OPTION GRANTOR Option or such shares are then free and clear
of all liens, claims, damages, charges and encumbrances of any
kind or nature whatsoever.

          (d)  OPTION HOLDER "CALL".  If OPTION HOLDER has
elected to purchase OPTION GRANTOR Shares pursuant to the
exercise of the OPTION GRANTOR Option by the issuance and
delivery of OPTION HOLDER Shares, notwithstanding that OPTION
HOLDER may no longer hold any such OPTION GRANTOR Shares or that
OPTION HOLDER elects not to exercise its other rights under this
Section 8, OPTION HOLDER may require, at any time or from time to
time prior to May 10, 1997 (provided that such date shall be
extended to May 10, 1998 under the circumstances where the date
after which either party may terminate the Merger Agreement
pursuant to Section 10.1(b) of the Merger Agreement has been
extended to May 10, 1998), OPTION GRANTOR to sell to OPTION
HOLDER any such OPTION HOLDER Shares at the price attributed to
such OPTION HOLDER Shares pursuant to Section 4 plus interest at
the rate of 8.75% per annum on such amount from the Closing Date
relating to the exchange of such OPTION HOLDER Shares pursuant to
Section 4 to the Closing Date under this Section 8(d) less any
dividends on such OPTION HOLDER Shares paid during such period or
declared and payable to stockholders of record on a date during
such period.

          (e)  REPURCHASE PRICE REDUCED AT OPTION HOLDER'S
OPTION.  In the event the repurchase price specified in Section
8(a) would subject the purchase of the OPTION GRANTOR Option or
the OPTION GRANTOR Shares purchased by OPTION HOLDER pursuant to
the OPTION GRANTOR Option to a vote of the shareholders of OPTION
GRANTOR pursuant to applicable law or the OPTION GRANTOR
Articles, then OPTION HOLDER may, at its election, reduce the
repurchase price to an amount which would permit such repurchase
without the necessity for such a shareholder vote.

          9.   VOTING OF SHARES.  Following the date hereof and
prior to the fifth anniversary of the date hereof (the
"Expiration Date"), each party shall vote any shares of capital
stock of the other party acquired by such party pursuant to this
Agreement ("Restricted Shares"), including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise beneficially
owned (within the meaning of Rule 13d-3 promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange
Act")), by such party on each matter submitted to a vote of
shareholders of such other party for and against such matter in
the same proportion as the vote of all other shareholders of such
other party are voted (whether by proxy or otherwise) for and
against such matter.

          10.  RESTRICTIONS ON TRANSFER.

          (a)  RESTRICTIONS ON TRANSFER.  Prior to the Expiration
Date, neither party shall, directly or indirectly, by operation
of law or otherwise, sell, assign, pledge, or otherwise dispose
of or transfer any Restricted Shares beneficially owned by such
party, other than (i) pursuant to Section 8, or (ii) in
accordance with Section 10(b) or Section 11.

          (b)  PERMITTED SALES.  Following the termination of the
Merger Agreement, a party shall be permitted to sell any
Restricted Shares beneficially owned by it if such sale is made
pursuant to a tender or exchange offer that has been approved or
recommended, or otherwise determined to be fair to and in the
best interests of the shareholders of the other party, by a
majority of the members of the Board of Directors of such other
party, which majority shall include a majority of directors who
were directors prior to the announcement of such tender or
exchange offer.

          11.  REGISTRATION RIGHTS.

          (a)  Following the termination of the Merger Agreement,
either party hereto that owns Restricted Shares (a "Designated
Holder") may by written notice (the "Registration Notice") to the
other party (the "Registrant") request the Registrant to register
under the Securities Act all or any part of the Restricted Shares
beneficially owned by such Designated Holder (the "Registrable
Securities") pursuant to a bona fide firm commitment underwritten
public offering, in which the Designated Holder and the
underwriters shall effect as wide a distribution of such
Registrable Securities as is reasonably practicable and shall use
their best efforts to prevent any person (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates
from purchasing through such offering Restricted Shares
representing more than 1% of the outstanding shares of common
stock of the Registrant on a fully diluted basis (a "Permitted
Offering").

          (b)  The Registration Notice shall include a
certificate executed by the Designated Holder and its proposed
managing underwriter, which underwriter shall be an investment
banking firm of nationally recognized standing (the "Manager"),
stating that

               (i)  they have a good faith intention to commence
     promptly a Permitted Offering, and

               (ii)  the manager in good faith believes that,
     based on the then-prevailing market conditions, it will be
     able to sell the Registrable Securities at a per share price
     equal to at least 80% of the then Fair Market Value of such
     shares.

          (c)  The Registrant (and/or any person designated by
the Registrant) shall thereupon have the option exercisable by
written notice delivered to the Designated Holder within ten
business days after the receipt of the Registration Notice,
irrevocably to agree to purchase all or any part of the
Registrable Securities proposed to be so sold for cash at a price
(the "Option Price") equal to the product of (i) the number of
Registrable Securities to be so purchased by the Registrant and
(ii) the then Fair Market Value of such shares.

          (d)  Any purchase of Registrable Securities by the
Registrant (or its designee) under Section 11(c) shall take place
at a closing to be held at the principal executive offices of the
Registrant or at the offices of its counsel at any reasonable
date and time designated by the Registrant and/or such designee
in such notice within twenty business days after delivery of such
notice, and any payment for the shares to be so purchased shall
be made by delivery at the time of such closing in immediately
available funds.

          (e)  If the Registrant does not elect to exercise its
option pursuant to this Section 11 with respect to all
Registrable Securities, it shall use its best efforts to effect,
as promptly as practicable, the registration under the Securities
Act of the unpurchased Registrable Securities proposed to be so
sold; provided, however, that

               (i)  neither party shall be entitled to demand
     more than an aggregate of two effective registration
     statements hereunder, and

               (ii) the Registrant will not be required to file
     any such registration statement during any period of time
     (not to exceed 40 days after such request in the case of
     clause (A) below or 90 days in the case of clauses (B) and
     (C) below) when

                    (A)  the Registrant is in possession of
          material non-public information which it reasonably
          believes would be detrimental to be disclosed at such
          time and, in the opinion of counsel to the Registrant,
          such information would be required to be disclosed if a
          registration statement were filed at that time;

                    (B)  the Registrant is required under the
          Securities Act to include audited financial statements
          for any period in such registration statement and such
          financial statements are not yet available for
          inclusion in such registration statement; or

                    (C)  the Registrant determines, in its
          reasonable judgment, that such registration would
          interfere with any financing, acquisition or other
          material transaction involving the Registrant or any of
          its affiliates.

          (f)  The Registrant shall use its reasonable best
efforts to cause any Registrable Securities registered pursuant
to this Section 11 to be qualified for sale under the securities
or Blue Sky laws of such jurisdictions as the Designated Holder
may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, however,
that the Registrant shall not be required to qualify to do
business in, or consent to general service of process in, any
jurisdiction by reason of this provision.

          (g)  The registration rights set forth in this Section
11 are subject to the condition that the Designated Holder shall
provide the Registrant with such information with respect to such
holder's Registrable Securities, the plans for the distribution
thereof, and such other information with respect to such holder
as, in the reasonable judgment of counsel for the Registrant, is
necessary to enable the Registrant to include in such
registration statement all material facts required to be
disclosed with respect to a registration thereunder.

          (h)  A registration effected under this Section 11
shall be effected at the Registrant's expense, except for
underwriting discounts and commissions and the fees and the
expenses of counsel to the Designated Holder, and the Registrant
shall provide to the underwriters such documentation (including
certificates, opinions of counsel and "comfort" letters from
auditors) as is customary in connection with underwritten public
offerings as such underwriters may reasonably require.

          (i)  In connection with any registration effected under
this Section 11, the parties agree

          (i)   to indemnify each other and the underwriters in
     the customary manner,

          (ii)  to enter into an underwriting agreement in form
     and substance customary for transactions of such type with
     the Manager and the other underwriters participating in such
     offering, and

          (iii) to take all further actions which shall be
     reasonably necessary to effect such registration and sale
     (including if the Manager deems it necessary, participating
     in road-show presentations).

          (j)  The Registrant shall be entitled to include (at
its expense) additional shares of its common stock in a
registration effected pursuant to this Section 11 only if and to
the extent the Manager determines that such inclusion will not
adversely affect the prospects for success of such offering.

          12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION. 
Without limitation to any restriction on OPTION GRANTOR contained
in this Agreement or in the Merger Agreement, in the event of any
change in OPTION GRANTOR Common Stock by reason of stock
dividends, splitups, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or the like,
the type and number of shares or securities subject to the OPTION
GRANTOR Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to OPTION
HOLDER its rights hereunder, including the right to purchase from
OPTION GRANTOR (or its successors) shares of OPTION GRANTOR
Common Stock (or such other shares or securities into which
OPTION GRANTOR Common Stock has been so changed) representing the
Option Shares Percentage of the Initial Number of shares of
OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in
Section 1.

          13.  RESTRICTIVE LEGENDS.  Each certificate
representing OPTION GRANTOR Shares issued to OPTION HOLDER
hereunder, and OPTION HOLDER Shares, if any, delivered to OPTION
GRANTOR at a Closing, shall include a legend in substantially the
following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY BE REOFFERED
     OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH
     REGISTRATION IS AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT
     TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,
     DATED AS OF NOVEMBER 10, 1995, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:

               (i)  the reference to the resale restrictions of
     the Securities Act and state securities or Blue Sky laws in
     the above legend shall be removed by delivery of substitute
     certificate(s) without such reference if OPTION HOLDER or
     OPTION GRANTOR, as the case may be, shall have delivered to
     the other party a copy of a letter from the staff of the
     SEC, or an opinion of counsel, in form and substance
     satisfactory to the other party, to the effect that such
     legend is not required for purposes of the Securities Act or
     such laws;

               (ii)  the reference to the provisions to this
     Agreement in the above legend shall be removed by delivery
     of substitute certificate(s) without such reference if the
     shares have been sold or transferred in compliance with the
     provisions of this Agreement and under circumstances that do
     not require the retention of such reference; and

               (iii)  the legend shall be removed in its entirety
     if the conditions in the preceding clauses (i) and (ii) are
     both satisfied.

In addition, such certificates shall bear any other legend as may
be required by law.  Certificates representing shares sold in a
registered public offering pursuant to Section 11 shall not be
required to bear the legend set forth in this Section 13.

          14.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY
BENEFICIARIES.  (a)  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

          (b)  Except as expressly provided for in this
Agreement, neither this Agreement nor the rights or obligations
of either party hereto are assignable, except by operation of
law, or with the written consent of the other party.

          (c)  Nothing contained in this Agreement, express or
implied, is intended to confer upon any person other than the
parties hereto and their respective permitted assigns any rights
or remedies of any nature whatsoever by reason of this Agreement.

          (d)  Any Restricted Shares sold by a party in
compliance with the provisions of Section 11 shall, upon
consummation of such sale, be free of the restrictions imposed
with respect to such shares by this Agreement, unless and until
such party shall repurchase or otherwise become the beneficial
owner of such shares, and any transferee of such shares shall not
be entitled to the registration rights of such party.

          15.  SPECIFIC PERFORMANCE.  The parties hereto agree
that irreparable harm would occur in the event that any of the
provisions of this Agreement were not performed in accordance
with their specified terms or were otherwise breached.  It is
accordingly agreed that the parties hereto shall be entitled to
an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which
they are entitled at law or equity.

          16.  VALIDITY.  (a)  The invalidity or unenforceability
of any provision of this Agreement shall not affect the validity
or enforceability of the other provisions of this Agreement,
which shall remain in full force and effect.

          (b)  In the event any court or other competent
authority holds any provisions of this Agreement to be null, void
or unenforceable, the parties hereto shall negotiate in good
faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the
extent permitted by law, the intent of the parties hereto with
respect to such provision and the economic effects thereof.

          (c)  Subject to Section 5, if for any reason any such
court or regulatory agency determines that OPTION HOLDER is not
permitted to acquire, or OPTION GRANTOR is not permitted to
repurchase pursuant to Section 8, the full number of shares of
OPTION GRANTOR Common Stock provided in Section 1 hereof (as the
same may be adjusted), it is the express intention of OPTION
GRANTOR to allow OPTION HOLDER to acquire or to require OPTION
GRANTOR to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof.

          (d)  Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part
hereof to be null, void or unenforceable, or order any party to
take any action inconsistent herewith, or not take any action
required herein, the other party shall not be entitled to
specific performance of such provision or part hereof or to any
other remedy, including but not limited to money damages, for
breach hereof or of any other provision of this Agreement or part
hereof as the result of such holding or order.

          17.  NOTICES.  All notices and other communications

                 PRESS RELEASE - November 11, 1995          EX-99
           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 ear.  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.
