                    PRELIMINARY COPY --SUBJECT TO COMPLETION
                   [LETTERHEAD OF MIDAMERICAN ENERGY COMPANY]



                                                                         , 1996

Dear IES Shareholder:

        On August 4, 1996,  MidAmerican  Energy  Company  proposed a combination
with IES Industries Inc. that would create a strong Iowa-based utility and bring
much  greater  value  to the  shareholders,  customers  and  employees  of  both
companies. In the proposed transaction, IES would merge with MidAmerican or with
a subsidiary  of  MidAmerican  and IES common  shareholders  would  receive,  in
exchange  for  their  IES  common  stock,  up to 40% cash and the  remainder  in
MidAmerican common stock. IES shareholders choosing cash will receive $39.00 per
share and those choosing stock will receive,  on a tax-free basis,  2.346 shares
of  MidAmerican  common  stock (with a market value of $39.00 per share based on
the August 2, 1996  closing  price of  MidAmerican  common stock on the New York
Stock Exchange) for each share of IES common stock.

        For the  reasons  set forth in this  letter and the  accompanying  proxy
statement, we believe the proposed MidAmerican Merger is financially superior to
the proposed  three-way  combination (the "Proposed  Wisconsin  Transaction") of
IES, Interstate Power Company ("Interstate") and WPL Holdings,  Inc. ("WPL"). We
also  believe  that  MidAmerican  and IES now have an  extraordinary  and timely
opportunity  to build on our mutual  strengths for the benefit of  shareholders,
customers and employees.

        WE URGE YOU TO VOTE  AGAINST  THE  PROPOSED  WISCONSIN  TRANSACTION  AND
PRESERVE  YOUR  OPPORTUNITY  TO CONSIDER  THE HIGHER  MARKET  VALUE  MIDAMERICAN
MERGER.  VOTE AGAINST THE  WISCONSIN  MERGER  AGREEMENT  BY SIGNING,  DATING AND
MAILING THE ENCLOSED BLUE PROXY CARD TODAY.

        Our August 4 proposal is the latest in a series of efforts  that we have
made to engage IES management in discussions concerning the benefits of a merger
between IES and  MidAmerican.  In August 1995 we  discussed a possible  business
combination with IES' Chief Executive  Officer.  Following that  discussion,  by
letters  dated  October 3 and  October  10,  1995,  we  attempted  to commence a
dialogue concerning a combination, which IES rebuffed. Our efforts culminated in
our October 23, 1995  request in  accordance  with a 1993  standstill  agreement
between IES and a predecessor of MidAmerican,  for permission from the IES Board
of Directors to propose a business  combination between MidAmerican and IES. IES
responded  that its Board of Directors  would  consider  our request.  Two weeks
later,  however,  IES  announced  that  it had  entered  into  an  agreement  to
participate  in the Proposed  Wisconsin  Transaction  which  includes terms less
favorable to IES and its  shareholders  than those we had proposed,  including a
notable reduction in your dividend.

            WE BELIEVE THE MIDAMERICAN MERGER IS FINANCIALLY SUPERIOR

        The MidAmerican Merger is financially superior.  Consider the following:

*       Greater Value. Based on closing stock prices for Friday, August 2, 1996,
        the  MidAmerican  Merger would  provide IES  shareholders  a 31% premium
        above  IES's  market  price as  compared  to only an 8%  premium  in the
        Wisconsin Transaction.  The MidAmerican Merger, therefore, would offer a
        21%  premium  ($6.81  per IES  share)  above  the  implied  value of the
        Proposed Wisconsin Transaction.
                                       -2-
<PAGE>

*       Substantially Higher Dividend.  The MidAmerican Merger would allow IES 
        shareholders to receive a  pro forma dividend of $2.82 per IES share, 
        a 34% increase above IES' current dividend rate, as compared to the  
        anticipated pro forma dividend of $1.99 in the Proposed Wisconsin  
        Transaction  which  is  a 5%  reduction  below  IES'  current dividend 
        rate. The MidAmerican Merger, therefore, would offer a dividend which 
        is $0.83 per share, or 42% higher,  than in the Proposed Wisconsin
        Transaction.

*       Choice  of Cash  or  Stock.  The  MidAmerican  Merger  would  allow  IES
        shareholders  a choice  of cash or,  on a  tax-free  basis,  stock in an
        Iowa-based  company  that  we  believe  will  be  a  stronger  and  more
        competitive total energy provider for Iowa, with an aggressive  regional
        growth strategy. IES common shareholders electing to receive stock would
        receive 2.346 shares of MidAmerican common stock (worth $39.00 per share
        based on the  closing  price of  MidAmerican  common  stock on August 2,
        1996) for each IES share.

        WE BELIEVE THAT THE MIDAMERICAN MERGER IS FINANCIALLY SUPERIOR TO
THE PROPOSED WISCONSIN TRANSACTION.  UNLESS THE PROPOSED WISCONSIN
TRANSACTION IS DEFEATED AT THE IES ANNUAL MEETING, YOU WILL NOT HAVE THE
OPPORTUNITY TO CONSIDER THE MIDAMERICAN MERGER.

             THE MIDAMERICAN MERGER WOULD CREATE A STRONGER COMPANY

        In addition to the substantial  financial  benefits to IES shareholders,
we believe that the MidAmerican  Merger is better for IES' employees,  customers
and the Iowa communities it serves. Among the many advantages of the MidAmerican
Merger would be:

*       More than $500  million in cost  savings.  Based  exclusively  on public
        information  relating to IES, we have identified  aggregate cost savings
        of  more  than  $500  million  during  the  first  ten  years  following
        completion of the MidAmerican Merger. Because cost savings estimates are
        necessarily based upon certain  assumptions about the future,  there can
        be  no  assurance  that  the  cost  savings  estimated  for  either  the
        MidAmerican  Merger  or  the  Proposed  Wisconsin  Transaction  will  be
        realized in such  amounts  and actual  cost  savings may be more or less
        than those estimated.

*       MidAmerican's  Merger  Integration Track Record.  The MidAmerican Merger
        offers IES  shareholders an opportunity to take advantage of MidAmerican
        management's  proven track record of successfully  integrating  mergers,
        including   expeditiously   obtaining  regulatory  approvals,   so  that
        shareholders and customers may promptly realize merger related benefits.


                             YOUR VOTE IS ESSENTIAL

        IF YOU WANT TO HAVE AN OPPORTUNITY TO CONSIDER THE  MIDAMERICAN  MERGER,
WHICH WE BELIEVE IS FINANCIALLY SUPERIOR TO THE PROPOSED WISCONSIN  TRANSACTION,
WE  URGE  YOU TO VOTE  THE  BLUE  PROXY  CARD  AGAINST  THE  PROPOSED  WISCONSIN
TRANSACTION.

                                       of
                           MIDAMERICAN ENERGY COMPANY


        This  Proxy  Statement  is  furnished  by  MidAmerican   Energy  Company
("MidAmerican")  in connection  with its  solicitation of proxies to be voted at
the annual meeting of shareholders of IES Industries Inc.  ("IES") to be held on
Thursday,  September  5, 1996 at Collins  Plaza  Hotel,  1200 Collins Road N.E.,
Cedar  Rapids,  Iowa,  at  10:00  a.m.  local  time,  and at  any  adjournments,
postponements  or  reschedulings  thereof  (the  "Annual  Meeting").  This Proxy
Statement is first being mailed to holders of  outstanding  shares of IES common
stock (the "IES Shares") on or about August __, 1996.

        On August 4, 1996, in a letter to IES,  MidAmerican proposed a merger of
the two companies that MidAmerican believes constitutes a significantly superior
financial transaction for holders of the IES Shares ("IES Shareholders"),  and a
far better transaction for IES' employees, customers and the Iowa communities it
serves,  than the Proposed Wisconsin  Transaction (as defined below).  Under the
MidAmerican  proposal,  IES  would  merge  with and into  MidAmerican  or with a
subsidiary of MidAmerican (the  "MidAmerican  Merger") in a transaction in which
IES  Shareholders  would  receive up to 40% cash and the  remainder in shares of
MidAmerican  common stock, to be allocated in accordance with customary election
and allocation procedures.  IES Shareholders receiving cash would receive $39.00
for each IES Share and IES  Shareholders  receiving  stock would  receive  2.346
shares of  MidAmerican  common  stock  (with a market  value of $39.00 per share
based on the closing price on the New York Stock Exchange on August 2, 1996) for
each IES Share.

        At the  Annual  Meeting,  IES  Shareholders  of  record  at the close of
business on July 10, 1996 (the  "Record  Date") will be voting on the  following
matters:

     1.   A proposal to approve the  Agreement  and Plan of Merger,  dated as of
          November 10,  1995,  as amended (the  "Wisconsin  Merger  Agreement"),
          among Interstate Power Company, a Delaware corporation ("Interstate"),
          WPL  Holdings,  Inc., a Wisconsin  corporation  ("WPL"),  IES, an Iowa
          corporation,  WPLH  Acquisition  Co., a  Wisconsin  corporation  and a
          wholly-owned  subsidiary of WPL ("Acquisition"),  and Interstate Power
          Company, a Wisconsin corporation and a wholly- owned subsidiary of WPL
          ("IPC").  The  Wisconsin  Merger  Agreement  provides  for a three-way
          business  combination  of  IES,  Interstate  and  WPL  (the  "Proposed
          Wisconsin   Transaction").   The  Proposed  Wisconsin  Transaction  is
          described herein under "Background of the Solicitation-- The Wisconsin
          Merger Agreement."

                                      -6-
<PAGE>

     2.   A proposal to elect a board of nine  directors to serve until the next
          annual  meeting  or  until  their  successors  are  duly  elected  and
          qualified.

     3.   Such other  business  as may  properly  come before the meeting or any
          adjournment or postponement thereof.

        Management  of IES  has  rejected  MidAmerican's  repeated  attempts  to
commence  a  dialogue  concerning  the  benefits  of a  merger  between  IES and
MidAmerican  and has  thereby  refused to let the IES  Shareholders  realize the
benefits of such a combination.  Instead, management of IES has chosen to pursue
the Proposed  Wisconsin  Transaction,  even though,  in MidAmerican's  view, the
Proposed Wisconsin Transaction offers IES Shareholders  significantly less value
and far lower dividends.

        The purpose of the solicitation made by this Proxy Statement (the "Proxy
Solicitation")  is to enable the IES  Shareholders,  the true  owners of IES, to
decide  for  themselves  which  proposal  is  financially  superior  and  to act
accordingly and in their own best interests.

        MIDAMERICAN  URGES YOU TO VOTE  AGAINST THE APPROVAL AND ADOPTION OF THE
WISCONSIN  MERGER AGREEMENT AND THE PROPOSED  WISCONSIN  TRANSACTION TO PRESERVE
YOUR OPPORTUNITY TO CONSIDER THE MIDAMERICAN MERGER,  WHICH MIDAMERICAN BELIEVES
IS FINANCIALLY SUPERIOR TO THE PROPOSED WISCONSIN TRANSACTION.

        IF YOU WANT TO HAVE AN OPPORTUNITY TO CONSIDER THE  MIDAMERICAN  MERGER,
VOTE AGAINST THE APPROVAL AND ADOPTION OF THE WISCONSIN MERGER AGREEMENT AND THE
PROPOSED WISCONSIN TRANSACTION BY SIGNING,  DATING AND MAILING THE ENCLOSED BLUE

                                  INTRODUCTION

        On August 4, 1996,  MidAmerican  Energy Company proposed a merger of IES
Industries  Inc. with and into  MidAmerican  or a subsidiary of MidAmerican in a
transaction  in which  IES  Shareholders  would  receive  up to 40% cash and the
remainder in  MidAmerican  common  stock,  to be allocated  in  accordance  with
customary election and allocation  procedures.  IES Shareholders  receiving cash
will receive $39.00 per share and IES  Shareholders  electing stock will receive
2.346  shares of  MidAmerican  common  stock (with a market  value of $39.00 per
share  based on the  closing  price on the New York Stock  Exchange on August 2,
1996) for each IES Share.  MidAmerican's  August 4 merger proposal is the latest
in a series of  MidAmerican's  efforts to engage IES  management in  discussions
concerning  the  benefits  of  such a  combination.  In  August  1993,  IES  and
Iowa-Illinois Gas and Electric Company  ("Iowa-Illinois"),  one of MidAmerican's
predecessors,  exchanged confidential information in connection with preliminary
discussions regarding a possible business  combination.  In connection with such
exchange of information,  IES and Iowa-Illinois  agreed that, prior to August 1,
1996, neither party nor its affiliates (which could include  MidAmerican) would,
without the prior written  consent of the board of directors of the other party,
acquire,  agree to acquire or make any proposal to acquire any securities of the
other  party  or any of  its  subsidiaries,  make,  or in any  way  participate,
directly  or  indirectly,  in any  solicitation  of proxies to vote,  or seek to
advise or  influence  any  person  with  respect  to the  voting  of, any voting
securities of the other party or any of its  subsidiaries  or take certain other
actions  concerning a merger with IES. See  "Background of the  Solicitation  --
Prior Communications with IES."

        In August 1995, the Chief  Executive  Officers of MidAmerican  expressed
MidAmerican's  interest in a combination  with IES in a  conversation  with IES'
Chief Executive Officer.  Thereafter, by letters dated October 3 and October 10,
1995,  MidAmerican  attempted to commence a dialogue  regarding  the benefits of
such a  combination,  which IES  rebuffed.  MidAmerican's  efforts  to discuss a
business  combination with IES culminated in an October 23, 1995 written request
by  MidAmerican  for  permission  from the Board of  Directors  of IES (the "IES
Board") to propose a  business  combination  between  MidAmerican  and IES.  IES
responded that the IES Board would consider the matters raised by the October 23
letter at its  meeting  in  November  1995 and that  until then IES would not be
interested in participating  with  MidAmerican in any discussions  relating to a
business combination  transaction.  See "Background of the Solicitation -- Prior
Communications with IES."

        Two weeks later,  on November 11, 1995, IES announced that it had agreed
to enter into the Proposed Wisconsin  Transaction,  in which IES, Interstate and
WPL  would  participate  in  a  three-way  business  combination.  The  Proposed
Wisconsin  Transaction  includes  terms  less  favorable  to  IES  and  the  IES
Shareholders  than both those proposed on October 23, 1995 and those proposed on
August 4, 1996,  including  a notable  reduction  in the  dividend.  MidAmerican
believes  the  MidAmerican   Merger  would  be  financially   superior  for  IES
Shareholders  and would better serve the interests of IES' employees,  customers
and the Iowa communities it serves than the Proposed Wisconsin Transaction.

        IF YOU WANT THE OPPORTUNITY TO BENEFIT FROM THE MIDAMERICAN  MERGER,  WE
URGE YOU TO PROMPTLY SIGN, DATE AND MAIL THE ENCLOSED BLUE PROXY TO VOTE AGAINST
THE APPROVAL AND ADOPTION OF THE  WISCONSIN  MERGER  AGREEMENT  AND THE PROPOSED
WISCONSIN TRANSACTION.

        In light of what MidAmerican believes to be the superior benefits of the
MidAmerican  Merger,  MidAmerican  believes  that it will be able to obtain  the
necessary  regulatory  approvals for the  MidAmerican  Merger on a timely basis.
Consequently,  MidAmerican believes the Proposed Wisconsin Transaction offers no
significant timing advantage over the MidAmerican Merger.

approval of numerous  regulatory  agencies,  including  (among  others) the Iowa
Utilities Board (the "IUB"),  the Illinois Commerce  Commission (the "ICC"), the
Minnesota  Public  Utilities  Commission  and the Public  Service  Commission of
Wisconsin.  IES and Interstate  jointly filed an application for approval of the
Proposed  Wisconsin  Transaction by the IUB. Their  application was subsequently
withdrawn  and no approval  has been  granted by the IUB. If IES and  Interstate
again file an application with the IUB,  MidAmerican intends to intervene in the
IUB proceedings.

        Regulatory  commissions reviewing the MidAmerican Merger or the Proposed
Wisconsin  Transaction  will be asked to take into account the greater  customer
benefits of the MidAmerican Merger when deciding to grant approval.  MidAmerican
believes that it will be able to obtain the necessary  regulatory  approvals for
the  MidAmerican  Merger  by the  end of  1997.  With  the  cooperation  of IES,
MidAmerican  believes that the MidAmerican  Merger could be completed  within 12
months after execution of a definitive merger agreement with IES.

        IES  Shareholders  would lose the  opportunity  to take advantage of the
benefits  of the  MidAmerican  Merger if they  approve  the  Proposed  Wisconsin
Transaction.  Thus,  MidAmerican  urges you to vote  against  the  approval  and
adoption  of  the  Wisconsin  Merger   Agreement  and  the  Proposed   Wisconsin
Transaction  to preserve your  opportunity to consider the  MidAmerican  Merger,
which  MidAmerican  believes is financially  superior to the Proposed  Wisconsin
Transaction.  If the IES  Shareholders  do not vote to  adopt  and  approve  the
Wisconsin Merger Agreement and the Proposed Wisconsin  Transaction,  MidAmerican
believes  the IES Board will  respect  the IES  Shareholders'  vote and take all
necessary  action in accordance with their fiduciary  duties to achieve the most
favorable  transaction for the IES  Shareholders.  We believe they will conclude
that the most favorable  transaction is the MidAmerican Merger.  There can be no
assurance, however, that the IES Board will act in accordance with the wishes of
the IES  Shareholders.  

                      PRESERVE YOUR OPPORTUNITY TO CONSIDER
                            THE MIDAMERICAN MERGER BY
                VOTING AGAINST THE PROPOSED WISCONSIN TRANSACTION

        The MidAmerican Merger cannot be proposed to IES Shareholders if the IES
Shareholders approve the Proposed Wisconsin  Transaction.  MidAmerican urges you
to vote against the Proposed Wisconsin Transaction and preserve your opportunity
to consider the MidAmerican Merger.

        MidAmerican believes that the MidAmerican Merger is financially superior
for the IES  Shareholders to either IES remaining  independent or IES completing
the  Proposed  Wisconsin  Transaction.  Advantages  of  the  MidAmerican  Merger
include, among others:

     *    Greater  Value.  Based on closing  stock prices for Friday,  August 2,
          1996, the MidAmerican Merger would provide IES Shareholders with a 31%
          premium  above IES' market  price as compared to only an 8% premium in
          the Proposed Wisconsin Transaction. The MidAmerican Merger, therefore,
          would  offer a 21%  premium  ($6.81 per IES Share)  above the  implied
          value of the Proposed Wisconsin Transaction.

     *    Substantially Higher Dividend.  The MidAmerican Merger would allow IES
          Shareholders to receive a pro forma dividend of $2.82 per IES Share, a
          34% increase  above IES'  current  dividend  rate,  as compared to the
          anticipated  pro forma  dividend  of $1.99 in the Proposed  Wisconsin 
          Transaction which is a 5% reduction -10-

<PAGE>

        below IES' current dividend rate. The MidAmerican Merger, therefore, 
        would offer a dividend which is $0.83 per share, or 42% higher, than in
        the Proposed Wisconsin Transaction.

*       Choice  of Cash  or  Stock.  The  MidAmerican  Merger  would  allow  IES
        Shareholders  a choice  of cash or,  on a  tax-free  basis,  stock in an
        Iowa-based company that MidAmerican believes will be a stronger and more
        competitive total energy provider for Iowa, with an aggressive  regional
        growth  strategy.  IES  Shareholders  electing  to receive  stock  would
        receive 2.346 shares of MidAmerican common stock (worth $39.00 per share
        based on the closing price of MidAmerican  common stock on August 2, 
        1996) for each IES Share.

*       More than $500  million in cost  savings.  Based  exclusively  on public
        information  relating to IES, we have identified  aggregate cost savings
        of  more  than  $500  million  during  the  first  ten  years  following
        completion of the MidAmerican Merger. Because cost savings estimates are
        based  upon  certain  assumptions  about  the  future,  there  can be no
        assurance  that the cost savings  estimated  for either the  MidAmerican
        Merger or the Proposed  Wisconsin  Transaction  will be realized in such
        amounts  and  actual  cost  savings  may be  more  or  less  than  those
        estimated.

*       MidAmerican's  Merger  Integration Track Record.  The MidAmerican Merger
        offers IES  Shareholders an opportunity to take advantage of MidAmerican
        management's  proven track record of successfully  integrating  mergers,
        including   expeditiously   obtaining  regulatory  approvals,   so  that
        shareholders and customers may promptly realize merger related benefits.


        A vote  AGAINST  the  approval  and  adoption  of the  Wisconsin  Merger
Agreement and the Proposed  Wisconsin  Transaction sends a strong message to the
IES Board that you want to preserve your opportunity to consider the MidAmerican
Merger,  which  MidAmerican  believes is  financially  superior to the  Proposed
Wisconsin Transaction.

        A vote  AGAINST  the  approval  and  adoption  of the  Wisconsin  Merger
Agreement and the Proposed Wisconsin  Transaction will preserve your opportunity
to consider the MidAmerican Merger and will move all IES Shareholders  closer to
being able to benefit from the MidAmerican Merger.

                         BACKGROUND OF THE SOLICITATION


Prior Communications with IES

        IES and MidAmerican and one of MidAmerican's predecessors have discussed
the  possibility  of a merger at various  times over the last  three  years.  In
August  1993,  IES  and  Iowa-Illinois  exchanged  confidential  information  in
connection  with   preliminary   discussions   regarding  a  possible   business
combination.  In  connection  with  those  discussions,  IES  and  Iowa-Illinois
executed a Confidentiality  and Standstill  Agreement.  In addition to customary
terms concerning the confidentiality and use of materials provided by each party
to the  other,  IES and  Iowa-Illinois  agreed  that,  prior to August 1,  1996,
neither  party nor its  affiliates  (which  could  include  MidAmerican)  would,
without the prior  written  consent of the board of directors of the other party
(i) in any manner  acquire,  agree to acquire or make any  proposal  to acquire,
directly  or  indirectly,  any  securities  of  the  other  party  or any of its
subsidiaries,  (ii) in any manner acquire, agree to acquire or make any proposal
to acquire,  directly or  indirectly,  any property of the other party or any of
its subsidiaries,  except in the ordinary course of business,  (iii) make, or in
any way participate,  directly or indirectly,  in any solicitation of proxies to
vote,  or seek to advise or influence  any person with respect to the voting of,
any voting securities of the other party or any of its subsidiaries,  (iv) form,
join or in any way  participate  in a "group"  (within  the  meaning  of Section
13(d)(3) of the  Securities  Exchange  Act of 1934,  as amended  (the  "Exchange
Act")) with  respect to any voting  securities  of the other party or any of its
subsidiaries,  (v) otherwise  act,  alone or in concert with others,  to seek to
control or influence the management, board of directors or policies of the other
party,  (vi) disclose any intention,  plan or arrangement  inconsistent with the
foregoing,  or (vii) advise, assist or encourage any other persons in connection
with any of the foregoing.  Each party also agreed,  for such period, not to (i)
request the other party or its representatives, directly or indirectly, to amend
or waive any such  obligation  or (ii) take any action  which might  require the
other  party  to make a  public  announcement  regarding  the  possibility  of a
business combination or merger.

        In August  1995,  following  the  merger of  Iowa-Illinois  and  Midwest
Resources Inc. ("Midwest Resources"),  Russell E. Christiansen,  Chairman of the
Board and Chairman of the Office of the Chief Executive  Officer of MidAmerican,
expressed  MidAmerican's  interest in a combination  with IES in a  conversation
with Lee Liu, Chairman, President and Chief Executive Officer of IES. On October
3, 1995, Mr. Christiansen and Stanley J. Bright,  President and President of the
Office  of the  Chief  Executive  Officer  of  MidAmerican,  wrote  to Mr.  Liu,
expressing their interest in such a combination, and explaining the synergies of
such a combination, describing the opportunity to create a strong  Iowa-based
utility  which would  continue to have a major impact on the economy of Iowa. In
the October 3 letter, Messrs.  Christiansen and Bright indicated that based on a
brief analysis,  a preliminary estimate of potential savings to be achieved in a
combination  of  MidAmerican  and IES would exceed $500  million.  On October 6,
1995,  Mr.  Liu  wrote  to  Messrs.  Christiansen  and  Bright  that IES was not
interested in entering into discussions with MidAmerican  relative to a possible
combination transaction.

        On October 10, 1995,  Messrs.  Christiansen  and Bright wrote to Mr. Liu
that they would  continue  to review and analyze  the  benefits of the  proposed
merger.  On October 23, 1995,  Messrs.  Christiansen and Bright wrote to Mr. Liu
requesting  that the IES Board  grant  MidAmerican  permission  to make an offer
whereby   MidAmerican  and  IES  would  participate  in  a  "merger  of  equals"
transaction  in which IES  Shareholders  would receive a premium of 15% over the
IES share price of $26.875 at October 20,  1995;  the  combined  MidAmerican/IES
would  continue  to maintain a  significant  and  appropriate  presence in Cedar
Rapids,  Iowa; IES  Shareholders  would have appropriate  representation  on the
board  of  directors  of  the   combined   MidAmerican/IES;   and  the  combined
MidAmerican/IES  would be organized as a holding  company exempt from regulation
under the Public Utilities Holding Company Act 

                                      -13-
<PAGE>

of 1935, as amended.  The October 23 letter urged Mr. Liu to meet with Messrs.  
Christiansen and Bright to discuss their request.

        On October 26, 1995,  Mr. Liu wrote to Messrs.  Christiansen  and Bright
that the IES Board would consider the matters raised by the October 23 letter at
its regular meeting in November 1995 and that until then IES would not be 
interested in participating with MidAmerican in any discussions relating to a 
business combination transaction.

        MidAmerican received no further  communication from IES. On November 11,
1995, IES announced that it had entered into the Wisconsin Merger Agreement.

The August 4 Offer and Related Actions

        On August 4, 1996,  MidAmerican  delivered  to Mr. Liu a letter  setting
forth  MidAmerican's  proposal that IES and  MidAmerican  effect the MidAmerican
Merger,  which, among other things,  would provide a premium of 31% over the IES
Share price of August 2, 1996 (the last trading day prior to such  letter).  The
letter also pointed out that a combination with  MidAmerican  would produce over
$500  million in  savings  during the ten years  following  consummation  of the
MidAmerican Merger.

        Shortly  after  delivery  of  the  letter,  MidAmerican  made  a  public
announcement  regarding  the  delivery of the August 4 letter and  released  the
letter to the Dow Jones News Service and other media outlets.

        On August 6,  1996,  MidAmerican  filed this  Proxy  Statement  with the
Securities  and  Exchange  Commission  for use in  soliciting  proxies  from IES
Shareholders against the approval and adoption of the Wisconsin Merger Agreement
and the Proposed Wisconsin Transaction.

The Wisconsin Merger Agreement

        Subject to the  alternative  structure  described  below,  the Wisconsin
Merger Agreement provides for: (i) the merger of IES with and into WPL (the "IES
Merger"),  pursuant  to which  each IES Share  (other  than  shares  held by IES
Shareholders who perfect  dissenters'  rights under Iowa law, and other than IES
Shares owned by WPL, IES or IPC or any of their respective  subsidiaries,  which
shares  will be  cancelled)  will be  converted  into the right to receive  1.01
shares  of  common  stock  of WPL,  which  will  be  renamed  Interstate  Energy
Corporation  ("Interstate  Energy"); and (ii) the merger of Acquisition with and
into Interstate, which merger will result in Interstate becoming a subsidiary of
Interstate Energy,  pursuant to which (a) each outstanding share of common stock
of Interstate (other than shares owned by WPL, IES or Interstate or any of their
respective subsidiaries,  which shares will be cancelled) will be converted into
the right to receive 1.11 shares of Interstate  Energy common stock and (b) each
outstanding  share of preferred  stock of Interstate  (other than shares held by
Interstate preferred  stockholders who perfect dissenters' rights under Delaware
law)  will  remain  outstanding.  Unless  regulatory  requirements  require  the
foregoing  transactions to be consummated pursuant to the alternative  structure
described  below,  such  transactions  will be effected in the manner  described
above. The Wisconsin Merger Agreement provides,  however,  that if, prior to the
consummation of the  transactions  described  above,  the constituent  companies
determine  that  certain  regulatory   requirements  mandate  that  the  utility
subsidiaries of Interstate  Energy be Wisconsin  corporations,  the transactions
will be  consummated  in a  manner  designed  to  comply  with  such  regulatory
requirements.  In that event,  the (i) IES Merger will be effected as  described
above and (ii) IES Utilities,  

                                      -14-

<PAGE>

an  Iowa   corporation  ("Utilities"),   will  be  merged  (the  "Utilities
Reincorporation   Merger")  with  and  into  IES  Utilities  Inc.,  a  Wisconsin
corporation  ("New  Utilities"),  pursuant  to which each  outstanding  share of
common  stock of Utilities  will be converted  into one share of common stock of
New Utilities. If the Utilities Reincorporation Merger is to be consummated,  it
is  currently  anticipated  that the  shares of  cumulative  preferred  stock of
Utilities  then   outstanding  will  be  redeemed  by  Utilities  prior  to  the
consummation of such merger.  Redemption of the Utilities preferred stock is not
expected  to occur as part of the  transactions  contemplated  by the  Wisconsin
Merger Agreement if the Utilities  Reincorporation  Merger is not required to be
effected. If the Utilities Reincorporation Merger is not effected, the Utilities
preferred  stock  will  remain  outstanding  and  unchanged  as a result  of the
transactions described herein. In addition, the merger involving Interstate will
be  reconstituted  to  provide  for (i) the  merger  of IPC  with  and  into New
Interstate Power Company, a Wisconsin corporation ("New IPC"), pursuant to which
(a) each outstanding  share of IPC common stock (other than shares owned by WPL,
IES or IPC  or any of  their  respective  subsidiaries,  which  shares  will  be
cancelled)  will be converted  into one share of common stock of New IPC and (b)
each  outstanding  share of IPC preferred stock (other than  dissenting  shares)
will be converted  into one share of  preferred  stock of New IPC with terms and
designations  under New IPC's Restated  Articles of Incorporation  substantially
identical to those of IPC's preferred stock under IPC's Restated  Certificate of
Incorporation,  including  certain  additional  voting  rights  proposed  to  be
approved  at IPC's  annual  meeting  of  shareholders;  and (ii) the  merger  of
Acquisition  with and into New IPC, which merger will result in New IPC becoming
a subsidiary of Interstate Energy,  pursuant to which (a) each outstanding share
of New IPC common stock (other than shares  owned by WPL, IES or  Interstate  or
any of their respective subsidiaries, which will be cancelled) will be converted
into the right to receive shares of Interstate  Energy common stock and (b) each
outstanding share of New IPC preferred stock (other than dissenting shares) will
remain outstanding.

        The  Proposed  Wisconsin  Transaction  is subject to certain  conditions
including,  among  others,  a  condition  that all  regulatory  and  shareholder
approvals be obtained.

        The Merger  Agreement may be terminated at any time prior to the Closing
Date,  whether  before or after  approval by the  shareholders  of WPL,  IES and
Interstate,  in various circumstances,  including:  (a) by any party thereto, if
the IES  Shareholders do not approve the Proposed  Wisconsin  Transaction at the
Annual  Meeting;  (b) by any  party  thereto,  by  written  notice  to the other
parties,  if the Proposed Wisconsin  Transaction shall not have been consummated
on or before May 10,  1997  (which date shall be extended to May 10, 1998 if the
required  statutory  approvals  and consents  have not been  obtained by May 10,
1997, but all other conditions to closing of the Proposed Wisconsin  Transaction
shall be, or shall be capable of being, fulfilled); provided, however, that such
right to terminate the Wisconsin  Merger  Agreement will not be available to any
party  whose  failure to  fulfill  any  obligation  under the  Wisconsin  Merger
Agreement  has been the cause of, or resulted  in, the failure of the  effective
time of the Proposed Wisconsin  Transaction to occur on or before that date; (c)
either WPL, IES or Interstate,  by written  notice to the other parties,  if (i)
there exist breaches of the representations and warranties on the part of either
of the other parties made in the Wisconsin  Merger Agreement or the Stock Option
Agreements  (as  defined   below)  as  of  the  date  thereof  which   breaches,
individually or in the aggregate,  would or would be reasonably likely to result
in a material  adverse  effect on the  business,  assets,  financial  condition,
results of  operations  or  prospects  of such other party and its  subsidiaries
taken as a whole,  and such breaches shall not have been remedied within 20 days
after receipt by the breaching party of notice in writing from the non-breaching
party or parties,  specifying  the nature of such breaches and  requesting  that
they be remedied;  (ii) either of the other parties  (and/or  their  appropriate
subsidiaries)  has not  performed  and  complied in all  respects  with  certain
agreements and covenants relating to the absence of changes in capitalization or
issuance of  securities  or has failed to perform and  comply,  in all  material
respects,  with its other  agreements and covenants  under the Wisconsin  Merger
Agreement or under the Stock Option  Agreements,  and such failure to perform or
comply has not been remedied within 20 days after receipt by the breaching party
of notice in writing from the non-breaching party, specifying the nature of such

                                      -15-
<PAGE>

failure and requesting  that it be remedied,  or (iii) the board of directors of
either of the other  parties or any  committee  thereof  (A) shall  withdraw  or
modify in any manner adverse to such party its approval or recommendation of the
Wisconsin  Merger  Agreement or the  ancillary  transactions,  (B) shall fail to
reaffirm such approval or  recommendation  upon such party's request,  (C) shall
approve  or  recommend  any  acquisition  of either of the  other  parties  or a
material  portion of their  assets or any  tender  offer for either of the other
parties'  common stock,  in each case by a party other than such party or any of
its  affiliates  or (D) shall  resolve to take any of the actions  specified  in
clause (A), (B), or (C).

     The  Wisconsin  Merger  Agreement  provides  that if the  Wisconsin  Merger
Agreement  is  terminated  by  WPL  and/or   Interstate   for  breaches  of  any
representations or warranties of IES contained in the Wisconsin Merger Agreement
as of  the  date  thereof,  or of  agreements  and  covenants  contained  in the
Wisconsin  Merger  Agreement  or the Stock  Option  Agreements,  pursuant to the
provisions of the Wisconsin  Merger  Agreement  described in clauses  (c)(i) and
(c)(ii) in the  previous  paragraph,  then if such breach is not  willful,  each
non-breaching party is entitled to reimbursement of its documented out-of-pocket
expenses, not to exceed $5,000,000 per each non-breaching party. In the event of
a willful breach by IES, the non-breaching  party or parties will be entitled to
its or their  out-of-pocket  expenses  and fees  (which  shall not be limited to
$5,000,000)  and any  remedies  it or they  may  have at law or in  equity,  and
provided  that if, at the time of IES' willful  breach,  there shall have been a
third-party  tender offer or proposal for a Business  Combination (as defined in
the  Wisconsin  Merger  Agreement)  which has not 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  become a subsidiary of such offeror or of an affiliate of such
offeror or accept an offer to consummate or  consummates a Business  Combination
with such third-party,  then IES, upon the closing of such Business Combination,
will pay to the non-breaching party or parties an additional aggregate fee equal
to $25,000,000.

        Additionally, the Merger Agreement would require payment of an aggregate
termination fee of $25,000,000,  together with  reimbursement  of  out-of-pocket
expenses,  by IES to the other parties in the following  circumstances:  (1) the
Merger Agreement is terminated (x) as a result of the acceptance by the IES of a
third-party tender offer or proposal for a Business Combination, (y) following a
failure  of the  IES  Shareholders  to  grant  their  approval  to the  Proposed
Wisconsin Transaction or (z) as a result of IES' material failure to convene the
Annual  Meeting,  distribute  proxy  materials  and,  subject to the IES Board's
fiduciary  duties,  recommend  the  Proposed  Wisconsin  Transaction  to the IES
Shareholders; (2) at the time of such termination or prior to the Annual Meeting
there has been a third-party tender offer or proposal for a Business Combination
which shall not have been rejected by IES or withdrawn by such third party;  and
(3) within two and one-half  years of any such  termination  described in clause
(1)  above,  IES  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.

        In addition to the  foregoing,  if the  Wisconsin  Merger  Agreement  is
terminated  under  circumstances  that give rise to the payment of a termination
fee by  Interstate  or WPL and within  nine  months of such  termination  IES is
acquired by the same third-party offeror which acquired the party which paid the
first  termination  fee,  the  sole  remaining  party  will  be  entitled  to an
additional termination payment by IES of $25,000,000.

        In connection  with the  execution and delivery of the Wisconsin  Merger
Agreement, IES, Interstate and WPL entered into reciprocal option grantor/option
holder  stock  option  and  trigger   payment   agreements  (the  "Stock  Option
Agreements") each granting the other two parties an irrevocable option (each, an
"Option") to purchase,  under  certain  circumstances,  a certain  percentage of
authorized  but  unissued  shares  of  the  respective   issuer's  common  stock
(representing  up to an aggregate of 19.9% of the outstanding  common stock (the
"Option  Shares") 
  
                                    -16-
<PAGE>

     of such issuer on November 10, 1995),  at an exercise  price of $30.675 per
share in the case of WPL  common  stock,  $26.7125  per share in the case of IES
Shares and $28.9375 per share in the case of Interstate common stock.

        In the event that the  Wisconsin  Merger  Agreement  becomes  terminable
under  circumstances  in which a termination fee could be payable by one or more
parties  (any such  party,  a "Payor")  pursuant  to the  immediately  preceding
paragraph,  the Stock Option  Agreements will entitle the other party or parties
to require the Payor or Payors to  repurchase  such Option or the Option  Shares
issued upon exercise thereof or to make a payment.  The termination fees payable
by IES under the foregoing  provisions plus the aggregate  amount which could be
payable by IES under the Stock Option Agreements may not exceed $40,000,000.

                           COMPARISON OF THE PROPOSALS


MidAmerican Merger Premium and Dividend Impact

        MidAmerican believes that the MidAmerican Merger is financially superior
to the Proposed Wisconsin Transaction. The closing price per IES Share on August
2, 1996 (the last trading day prior to the public  announcement  of the August 4
offer) was $29.75. The MidAmerican Merger would provide a substantial premium to
IES Shareholders in relation to that level, as shown by the following table:

        MidAmerican common stock).

        The MidAmerican  Merger would also provide a substantial  premium to IES
Shareholders in relation to the Proposed Wisconsin Transaction,  as shown by the

        will depend upon future earnings, the financial condition of MidAmerican
        and other  factors,  MidAmerican  does not  anticipate  any  significant
        change with respect to its historical  dividend  practice as a result of
        the MidAmerican Merger.

        The premium to IES Shareholders  receiving MidAmerican common stock will
change as the  market  prices of  MidAmerican  common  stock and the IES  Shares
change.  The dividend increase to IES Shareholders will not change as the market
prices of MidAmerican common stock or the IES Shares change.

Potential Cost Savings

        The analyses  discussed below include  forward  looking  statements that
involve  judgments,  assumptions and other  uncertainties  beyond the control of
MidAmerican.  As such,  there can be no assurance  that the cost savings will be
realized in the amounts  referred to herein and actual cost  savings may be more
or less than those projected. Such judgments,  assumptions and uncertainties are
discussed more fully below.

        MidAmerican  believes  that  the  IES  Shareholders,  as  well  as  IES'
customers,  employees and the communities it serves,  would realize  substantial
benefits from the MidAmerican Merger.  MidAmerican  believes such benefits would
be realized through the following operational and structural synergies:

     *    Operational coordination--The overlapping and contiguous nature of the
          respective  service  territories  of  MidAmerican  and IES, which both
          operate  in Iowa and whose  headquarters  are  within 125 miles of one
          another,  provide an opportunity to efficiently  integrate all aspects
          of  their  utility   operations.   MidAmerican  already  has  numerous
          substantial  electrical  interconnections  with IES and  provides  gas
          service in  locations  in which IES  provides  electric  service.  The
          combined  system  would be  expected  to  benefit  because it could be
          operated  as part of a larger,  cohesive  system,  with  virtually  no
          modification   needed  with   respect  to  existing   generating   and
          transmission  facilities,   in  contrast  to  the  Proposed  Wisconsin
          Transaction  which   contemplates  the  construction  of  transmission
          facilities to achieve full integration of its electrical  systems.  At
          present, MidAmerican and IES maintain joint interests in approximately
          1,233  megawatts of  generation  capacity  that accounts for more than
          $540 million in assets.

     *    Increased size and stability and more  integrated  product and service
          portfolio--As a larger entity,  a combined  MidAmerican/IES  will have
          more diverse generating,  transmission and customer bases and enhanced
          access   to   capital   markets.   As  a   consequence,   a   combined
          MidAmerican/IES  will  be  better  able to take  advantage  of  future
          strategic  opportunities  as  the  demands  of  a  competitive  market
          intensify, and to reduce exposure to changes in economic 

                                      -18-
<PAGE>

          conditions in any given segment of the business. The integration of 
          the gas and electric business segments would enable the combined
          MidAmerican/IES  to enhance the  portfolio  of products  and  services
          available  to  customers.  This  integration  of products and services
          would position  MidAmerican/IES as a premier provider of comprehensive
          energy solutions.

     *    Economic development opportunities--The combined MidAmerican/IES would
          be  able  to  concentrate  its  economic   development   programs  and
          activities rather than pursue parallel paths with respect to potential
          customers or industry  groups,  which would enhance the ability of the
          combined  MidAmerican/IES  to  attract or to retain  within  Iowa such
          potential customers or industry groups.

        MidAmerican believes that available synergies will generate cost savings
in  excess of $500  million  to the  combined  MidAmerican/IES  over a  ten-year
period.  Such cost savings are projected to begin in 1998 and increase each year
thereafter.  Such  estimates  are  based  on  a  review  of  publicly  available
information  performed by MidAmerican.  The major components of the anticipated
cost savings are as follows:

     Generation

     *    Integration of  dispatching  and electric  production  operations--The
          combined MidAmerican/IES could obtain fuel savings from joint dispatch
          of generating  capacity  that is not available  when the two companies
          are operated as two separate  systems.  Fuel savings would result from
          an  improved  ability  to  schedule  and  commit  each  of  the  base,
          intermediate and peak load facilities of the combined  MidAmerican/IES
          in a more economically efficient manner.

     *    Avoidance  or deferral of future  capital  expenditures--The  combined
          MidAmerican/IES  would have the ability to reduce future  expenditures
          for generating  capacity by coordinating  and optimizing  planning for
          future resources. The combination of the two companies would result in
          system diversity due to differences in the mix of generating  capacity
          currently  installed on each company's  system,  the electrical  loads
          placed on each system and the timing of peak demands. The  uncommitted
          generating  capacity  created  by  such  system diversity will result
          in the delay,  elimination or  substitution of  additional  capacity  
          now  planned  by  the  two  stand-alone companies.

     *    Integration  of  generation  and  technical   support   functions--The
          combined   MidAmerican/IES   would  be  able  to  eliminate  redundant
          functions in the areas of generation support,  such as system planning
          and fuels management.

     Field Operations

     *    Integration of distribution  operations--The  combined MidAmerican/IES
          would  have the  ability  to  consolidate  certain  customer  business
          offices and  service  centers in Iowa where  MidAmerican  and IES have
          contiguous or overlapping service territories.  The close proximity of
          these  operations  also enables  customer  service  functions  such as
          service  initiation and service  scheduling to be combined.  The close
          proximity of the two  companies  would enable work to be  reconfigured
          and resources to be shared in operations areas.

                                      -19-
<PAGE>


     *    Integration  of field and technical  support  functions--The  combined
          MidAmerican/IES  would be able to eliminate redundant functions in the
          area  of  distribution  support,  such as  engineering,  construction,
          operation and maintenance.

     Purchasing Economies

     *    Streamlining  of inventories  and purchasing  economies--The  combined
          MidAmerican/IES  would achieve savings through the  centralization  of
          purchasing and inventory functions related to construction,  operation
          and maintenance at generating plants, service centers,  warehouses and
          headquarters.  The  larger  size of the  Company  should  improve  its
          bargaining position in its purchases of fuel, gas supplies, materials,
          services and  equipment,  and thus result in lower unit costs for such
          items.

     Corporate and Administrative

     *    Integration of corporate management and administrative  functions--The
          combined   MidAmerican/IES   would  be  able  to  eliminate  redundant
          functions in the areas of finance, accounting, purchasing, shareholder
          relations,  human resources,  corporate planning, public relations and
          administration, among other areas. The payroll costs of such functions
          are  relatively  fixed and do not vary  directly  with an  increase or
          decrease in the number of customers served.

     *    Avoidance of future  information  systems  expenditures--The  combined
          MidAmerican/IES  would be able to eliminate  certain  operational  and
          capital  expenditures  in the area of management  information  systems
          that  would be made by each  company  on a  stand-alone  basis.  These
          avoided expenditures relate to operating systems, such as the customer
          information  and  geographic  information  systems,  that would not be
          wholly  duplicated in the combined  company.  Additional  expenditures
          could be reduced  through the more efficient  management of investment
          in other information  technology areas, such as in personal computers,
          mainframe upgrades and backup facilities.

     *    Consolidation  of corporate  programs and  expenditures--The  combined
          MidAmerican/IES   would   integrate   corporate   and   administrative
          functions,   thereby  reducing  certain  non-labor  costs,   including
          insurance  premiums,  audit and  consulting  fees,  bank service fees,
          professional  and trade  association  dues,  stock  transfer and other
          fees, vehicle expenses and various license fees, among others.


     Payroll Cost Reductions

     *    Payroll cost reductions--Based upon MidAmerican's  experience from the
          previous merger of Midwest Resources and Iowa-Illinois, in which total
          payroll  costs were  significantly  reduced and its  knowledge of IES,
          MidAmerican  believes that substantial  payroll cost reductions can be
          achieved by employing a combination of attrition,  controlled  hiring,
          retraining,  early retirements,  voluntary  separation,  other payroll
          reduction measures (if necessary) and better management programs, such
          as activity  standardization and technology  substitution.  As of June
          30, 1996,  MidAmerican had 3,532 full-time  employees.  As of December
          31,  1995,  according  to  IES'  publicly-filed   documents,  IES  had
          approximately  2,635  full-time   employees.   MidAmerican's  

                                      -20-
<PAGE>
          savings estimates  for the  MidAmerican  Merger  contemplate  a  
          reduction  of approximately 450 positions.

        While data  concerning  the  estimated  cost  savings  from the Proposed
Wisconsin Transaction set forth in the Joint Proxy  Statement/Prospectus of IES,
Interstate  and WPL dated July 11,  1996 (the  "IES/Interstate/WPL  Joint  Proxy
Statement/Prospectus")  reflect the benefits of complete access to personnel and
detailed  data within those  companies and the  identification  of specific cost
savings  categories,  MidAmerican  has  not  had  similar  access.  Nonetheless,
MidAmerican  believes that upon inspection of similar data and discussions  with
IES personnel, additional cost savings opportunities can be identified.

        Because  MidAmerican  was unable to discuss the above  analyses with IES
and did not have access to non-public material  concerning IES' operations,  the
foregoing  analyses  were  necessarily  limited  in scope to  matters  for which
information was publicly available. In addition, such analyses involve judgments
and contain  forward-looking  statements  with respect to,  among other  things,
normal weather conditions, future national and regional economic and competitive
conditions,  inflation  rates,  regulatory  treatment,  future  financial market
conditions,  interest rates, future business decisions and other  uncertainties,
which,  though considered  reasonable by MidAmerican,  are beyond  MidAmerican's
control and difficult to predict.  Accordingly,  there can be no assurance  that
such cost savings will be realized,  and actual cost savings may vary materially
from  those set forth  above.  In light of the  uncertainties  inherent  in such
analyses,  the inclusion of estimated cost savings herein should not be regarded
as a  representation  by  MidAmerican or any other person that such cost savings
will be achieved.

     Summary of Savings Assumptions

     The following is a summary of selected  significant  assumptions  made with
respect to the potential  synergies of the MidAmerican  Merger:  (i) the savings
period is 1998 through 2007; (ii) initial savings of approximately  $25 million,
increasing   annually   throughout  the  savings  period;   (iii)  the  combined
MidAmerican/IES  will be  organized as an  operating  utility with  consolidated
administrative  and support  functions;  (iv) synergies  reflect  merger-related
opportunities  only; (v) savings are exclusive of planned MidAmerican actions on
a stand-alone  basis and IES' planned  actions,  to the extent  disclosed;  (vi)
multiple  programs  will be utilized for payroll  reductions;  and (vii) payroll
reduction programs are consistent with recent experience.

Regulatory Plan

        The allocation of the benefits and cost savings outlined above among the
shareholders of MidAmerican and IES and their  respective  customers will depend
on the extent by which the rates of MidAmerican  and IES are adjusted to reflect
such benefits. Although no assurances can be given, MidAmerican anticipates that
such  adjustments  will  occur  through  approval  of  a  regulatory  plan  (the
"Regulatory Plan") that MidAmerican intends to propose in its application to the
IUB and the ICC seeking approval of the MidAmerican Merger.

     The Regulatory Plan is expected to reflect  MidAmerican's  current electric
pricing  targets for average  class  prices by June 1, 2001.  The average  price
targets  (including  fuel) are 8.54  cents  per  kilowatt  hour for  residential
customers,  6.92 cents per kilowatt hour for commercial customers and 4.26 cents
per kilowatt hour for industries  customers.  There can be no assurance that the
Regulatory  Plan  will  be  implemented  as  described   herein.   In  addition,
MidAmerican  reserves  the right to  propose  changes  to the  Regulatory  Plan,
including  changes  resulting  from  additional  information  about IES becoming
available to MidAmerican.

                                      -21-
<PAGE>


        MidAmerican  believes  that it will be  able  to  obtain  the  necessary
regulatory  approvals for the MidAmerican Merger on a timely basis and in a time
frame at least as  favorable as that in which IES,  Interstate  and WPL would be
able to obtain the necessary  approvals for the Proposed Wisconsin  Transaction.
With the cooperation of IES,  MidAmerican  believes that the MidAmerican  Merger
could be  completed  within 12 months from the date of execution of a definitive
merger agreement.

Regulatory Approvals

        Regulatory commissions reviewing the MidAmerican Merger and the Proposed
Wisconsin  Transaction  will be asked to take into account the greater  customer
benefits of the MidAmerican  Merger when deciding  between the  applications for
approval.

        The  consummation of the MidAmerican  Merger and the Proposed  Wisconsin
Transaction  both would be subject to approval of the IUB,  the ICC, the NRC and
the FERC, the  expiration or termination of the applicable  waiting period under
the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  as  amended,  and
certain other  miscellaneous  filings.  These are the only  material  regulatory
approvals required to effect the MidAmerican Merger. By contrast, in addition to
all of the  foregoing  required  regulatory  approvals,  the Proposed  Wisconsin
Transaction  would also require  approval  from the Minnesota  Public  Utilities
Commission  and the Public Service  Commission of Wisconsin.  IES and Interstate
jointly filed an application for approval of the Proposed Wisconsin  Transaction
by the IUB. Their  application  was  subsequently  withdrawn and no approval has
been granted by the IUB. If IES and Interstate  again file an  application  with
the IUB, MidAmerican intends to intervene in the IUB proceedings.

        In  light  of the  superior  value  of the  MidAmerican  Merger  and the
benefits of the Regulatory Plan described  above,  MidAmerican  believes that it
will be able to obtain the  necessary  regulatory  approvals for the Merger on a
timely  basis and in a time  frame at least as  favorable  as that in which IES,
Interstate  and WPL would be able to obtain the necessary  regulatory  approvals
for the Proposed Wisconsin Transaction.  Accordingly,  MidAmerican believes that
the  proposed  Wisconsin   Transaction  offers  no  timing  advantage  over  the
MidAmerican Merger.

Material Contracts Between MidAmerican and IES

     MidAmerican  and  Utilities,  a wholly  owned  subsidiary  of IES,  owns as
tenants in common  interests  in the George Neal  Generating  Station Unit No. 3
(MidAmerican:  72% pr 370  megawatts;  Utilities:  28% or 144 megawatts) and the
Ottumwa Generating Station (MidAmerican: 52% or 372 megawatts; Utilities: 48% or
343  megawatts).  MidAmerican  and IES are  common  owners  of the  George  Neal
Generating  Station 345  kilovolt  transmission  line.  Also,  each own separate
segments of the Twin Cities-Iowa-St.  Louis 345 kilovolt  transmission line, and
are common  owners along with another  utility of a substation  facility on that
line.  Also,  as a  result  of the  contiguous  nature  of the  MidAmerican  and
Utilities service territories,  the transmission  facilities of each company are
interconnected in several locations. MidAmerican and Utilities have entered into
inter- change agreements concerning such interconnections.

                           DESCRIPTION OF MIDAMERICAN


        MidAmerican  is  primarily   engaged  in  the  business  of  generating,
transmitting, distributing and selling electric energy and distributing, selling
and transporting  natural gas.  MidAmerican has two  wholly-owned  subsidiaries:
MidAmerican Capital Company  ("MidAmerican  Capital") and Midwest Capital Group,
Inc.   ("Midwest   Capital").   MidAmerican   Capital  engages  in  nonregulated
energy-related   businesses.   Midwest  Capital  conducts  economic  development
activities in the Company's service territory.

        The Company  distributes  electric energy in Council Bluffs, Des Moines,
Fort Dodge, Iowa City, Sioux City and Waterloo, Iowa, the Quad-Cities (Davenport
and Bettendorf,  Iowa and Rock Island,  Moline and East Moline,  Illinois) and a
number of adjacent communities and areas. The Company distributes natural gas in
Cedar Rapids, Des Moines, Fort Dodge, Iowa City, Sioux City and Waterloo,  Iowa,
the Quad-Cities, Sioux Falls, South Dakota; and a number of adjacent communities
and  areas.  The  population  of the  Company's  utility  service  territory  is
approximately  1.7 million.  As of December  31,  1995,  the Company had 635,000
retail electric customers and 601,000 natural gas customers.

        The Company has a residential,  agricultural, commercial and diversified
industrial customer group, in which no single industry or customer accounted for
more than 3.5% (food and kindred products  industry) of the Company's total 1995
electric  operating revenues or 3.6% (food and kindred products industry) of its
total 1995 gas  operating  margin.  Among the primary  industries  served by the
Company are those which are concerned  with the  manufacturing,  processing  and
fabrication  of primary  metals,  real  estate,  food  products,  farm and other
non-electrical  machinery,  and cement and gypsum  products.  For the year ended
December 31, 1995, the Company derived  approximately 64% of its gross operating
revenues from its electric business and 27% from its gas business.

        MidAmerican,  an Iowa  corporation,  was organized in 1995 to facilitate
the merger of  Iowa-Illinois,  Midwest  Resources and Midwest Power Systems Inc.
The merger was accounted for as a pooling of interests.  MidAmerican's corporate
headquarters  is located at 666 Grand  Avenue,  Des  Moines,  Iowa 50303 and its
telephone number is (515) 242-4300.

         In January 1996, MidAmerican's board of directors approved an Agreement
and Plan of Exchange  related to the formation of  MidAmerican  Energy  Holdings
Company  ("Holdings"),  a holding  company.  Holdings  initially will have three
wholly-owned subsidiaries, MidAmerican (utility operations), MidAmerican Capital
and MidWest Capital. Upon receipt from the ICC of an order approving the holding
company structure,  each share of MidAmerican common stock will be exchanged for
one share of Holdings common stock. It is MidAmerican's  intent, if possible, to
complete the formation of the holding  company and share  exchange by the end of
1996.

        MidAmerican is subject to the informational requirements of the Exchange
Act, and in accordance  therewith  files  reports,  proxy  statements  and other
information  with  the  Securities  and  Exchange  Commission.   Reports,  proxy
statements and other information filed by MidAmerican with the Commission may be
inspected  and  copied at the  public  reference  facilities  maintained  by the
Commission at Judiciary  Plaza, 450 Fifth Street,  N.W., Room 1024,  Washington,
D.C. 20549 and at the public reference  facilities in the Commission's  Regional
Offices at Seven World Trade Center,  13th Floor,  New York,  New York 10048 and
Citicorp Center, 500 West Madison Street,  Suite 1400, Chicago,  Illinois 60661.
Copies of information may be obtained from the Public  Reference  Section of the
Commission  at 450 Fifth  Street,  N.W.,  Washington,  D.C.  20549 at prescribed

                              VOTING OF PROXY CARDS

General

        Only IES  Shareholders  of record on July 10, 1996 are eligible to vote.
Therefore,  any IES  Shareholder  owning  Shares held in the name of a brokerage
firm,  bank, or other  institution  should sign,  date and return the BLUE proxy
card to such brokerage firm, bank or other  institution in the envelope provided
by that firm. The accompanying  BLUE proxy card will be voted in accordance with
the IES Shareholders' instructions on such BLUE proxy card.

Revocation Of Proxies

        An  executed  proxy may be revoked at any time prior to its  exercise by
submitting another proxy with a later date, by appearing in person at the Annual
Meeting and voting or by sending a written,  signed and dated  revocation  which
clearly  identifies the proxy being revoked to either (a) MidAmerican in care of
D.F. King & Co.,  Inc., 77 Water Street,  New York,  New York 10005,  or (b) the
principal  executive offices of IES at 200 First Street S.E., Cedar Rapids, Iowa
52406.  A revocation  may be in any written  form  validly  signed by the record
holder as long as it clearly states that the proxy previously given is no longer
effective.  MidAmerican  requests that a copy of any revocation sent to IES also
be sent to  MidAmerican in care of D.F. King & Co., Inc. at the above address so
that  MidAmerican  may more  accurately  determine if and when proxies have been
received from the holders of record on the Record Date.

        IF YOU HAVE  ALREADY SENT A GREEN PROXY CARD TO THE IES  DIRECTORS,  YOU
MAY  REVOKE  THAT  PROXY AND VOTE  AGAINST  THE  ADOPTION  AND  APPROVAL  OF THE
WISCONSIN  MERGER AGREEMENT AND THE PROPOSED  WISCONSIN  TRANSACTION BY SIGNING,
DATING AND MAILING THE ENCLOSED  BLUE PROXY CARD.  THE LATEST DATED PROXY IS THE
ONLY ONE THAT COUNTS.

Matters to be Voted on at the Annual Meeting

    The Wisconsin Merger Agreement and the Proposed Wisconsin Transaction

        IES  Shareholders  (i) may vote against the approval and adoption of the
Wisconsin  Merger Agreement and the Proposed  Wisconsin  Transaction or (ii) may
withhold  their vote or (iii) may vote for such approval and adoption by marking
the proper box on the BLUE proxy and signing,  dating and  returning it promptly
in the enclosed  postage-paid  envelope.  If an IES  Shareholder  returns a BLUE
proxy card that is signed,  dated and not marked,  that IES Shareholder  will be
deemed to have voted  against  approval  and  adoption of the  Wisconsin  Merger
Agreement and the Proposed Wisconsin Transaction.

        According to the  IES/Interstate/WPL  Joint Proxy  Statement/Prospectus,
each IES Share is entitled to one vote upon each matter  presented at the Annual
Meeting.  A majority of the votes  entitled to be cast by holders of IES Shares,
represented  in person or by proxy,  shall  constitute  a quorum for each matter
presented at the Annual Meeting. Abstentions and broker non-votes (i.e., proxies
from  brokers  or  nominees  indicating  that  such  person  have  not  received
instructions from the beneficial owners or other persons entitled to vote shares
as  to a  matter  with  respect  to  which  brokers  or  nominees  do  not  have
discretionary  power to vote)  will be  considered  present  for the  purpose of
establishing a quorum.  If a quorum is present,  (i) the  affirmative  vote of a
majority  of the votes  entitled  

                                      -25-

<PAGE>

to be cast by the  holders  of the IES  Shares entitled  to vote  thereon is 
required  for  approval  of the  Wisconsin  Merger Agreement,  and (ii) 
the affirmative vote of a majority of the votes entitled to be cast by the  
holders of IES Shares  represented  at the  Annual  Meeting  and entitled to 
vote thereon is required for the  election of  directors.  Under the IBCA, 
in determining whether the Wisconsin Merger Agreement and the nominees for
directors have received the requisite number of affirmative  votes,  abstentions
and broker non-votes will have the same effect as votes cast against  approval 
of the Wisconsin  Merger Agreement and against approval of the nominees  for  
director.  Failure  to return a proxy or to vote in person at the Annual Meeting
will also have the effect of a vote against the Wisconsin  Merger Agreement and 
against the nominees for director.

        MIDAMERICAN  URGES YOU TO VOTE  AGAINST THE APPROVAL AND ADOPTION OF THE
WISCONSIN  MERGER AGREEMENT AND THE PROPOSED  WISCONSIN  TRANSACTION IN ORDER TO
PRESERVE YOUR OPPORTUNITY TO CONSIDER THE MIDAMERICAN MERGER,  WHICH MIDAMERICAN
BELIEVES IS FINANCIALLY SUPERIOR TO THE PROPOSED WISCONSIN TRANSACTION.

        IF YOU WANT TO HAVE AN OPPORTUNITY TO CONSIDER THE  MIDAMERICAN  MERGER,
VOTE AGAINST THE APPROVAL AND ADOPTION OF THE WISCONSIN MERGER AGREEMENT AND THE
PROPOSED  WISCONSIN  TRANSACTION  BY SIGNING,  DATING AND RETURNING THE ENCLOSED
BLUE PROXY CARD TODAY.

    Approval of IES/Interstate/WPL Joint Proxy Statement/Prospectuss to be 
Considered at the Annual Meeting

        As set forth in the IES/Interstate/WPL Joint Proxy Statement/Prospectus,
at the Annual Meeting, IES Shareholders will be asked to approve (in addition to
the Wisconsin Merger Agreement and the Proposed  Wisconsin  Transaction) (i) the
election of nine director candidates named in the IES/Interstate/WPL Joint Proxy
Statement/Prospectus (the "Other Proposal"),  and (ii) such other matters as may
properly  come  before the Annual  Meeting or any  adjournment  or  postponement
thereof. MidAmerican is not making any recommendations on the Other Proposal.

        The  accompanying  BLUE proxy card will be voted in accordance with your
instructions  on such card.  You may vote for approval of the Other  Proposal or
vote against, or abstain from voting on, the approval of the  IES/Interstate/WPL
Joint  Proxy  Statement/Prospectus  by marking  the proper box on the BLUE proxy
card.  IF NO MARKING IS MADE,  YOU WILL BE DEEMED TO HAVE GIVEN A  DIRECTION  TO
ABSTAIN FROM VOTING THE SHARES  REPRESENTED  BY THE BLUE PROXY CARD WITH RESPECT
TO THE APPROVAL OF THE OTHER PROPOSAL.

    Other Proposals

        EXCEPT AS SET FORTH ABOVE,  MIDAMERICAN IS NOT AWARE OF ANY PROPOSALS TO
BE BROUGHT BEFORE THE ANNUAL  MEETING.  SHOULD OTHER PROPOSALS BE BROUGHT BEFORE
THE ANNUAL  MEETING,  THE PERSONS NAMED ON THE BLUE PROXY CARD WILL ABSTAIN FROM
VOTING ON SUCH PROPOSALS UNLESS SUCH PROPOSALS ADVERSELY AFFECT THE INTERESTS OF
MIDAMERICAN AS DETERMINED BY MIDAMERICAN IN ITS SOLE DISCRETION,  IN WHICH EVENT
SUCH PERSONS WILL VOTE ON SUCH PROPOSALS AT THEIR DISCRETION.

                               DISSENTERS' RIGHTS

        According to the  IES/Interstate/WPL  Joint Proxy  Statement/Prospectus,
the IBCA  provides  dissenters'  rights for IES  shareholders  who object to the
Proposed  Wisconsin  Transaction and meet the requisite  statutory  requirements
contained in Sections  490.1301 through 490.1331 of the IBCA.  Sections 490.1301
through  490.1331 of the IBCA are reprinted in their  entirety as Annex P to the
IES/Interstate/WPL Joint Proxy Statement/Prospectus.

     A  shareholder  may  dissent  as to less than all of the  shares of capital
stock  registered  in the  name of  such  shareholder  only if such  shareholder
dissents  with  respect to all shares  beneficially  owned by any one person and
notifies IES in writing of the name and address of each person whose behalf such
shareholder  asserts  dissenters'  rights. The rights of a partial dissenter are
determined  as if the  shares  of  capital  stock  as to which  the  shareholder
dissents and such shareholder's other shares of capital stock were registered in
the  names of  different  shareholders.  A  beneficial  shareholder  may  assert
dissenters' rights as to shares held on such  shareholder's  behalf only if such
shareholder (i) submits to IES the record  shareholder's  written consent to the
dissent not later than the time the beneficial  shareholder  asserts dissenters'
rights and (ii) asserts dissenters' rights with respect to all shares of capital
stock of which the shareholder is the beneficial  shareholder or over which such
beneficial shareholder has the power to direct the vote.

        The  IBCA  requires  that  an  IES  Shareholder  who  wishes  to  assert
dissenter's rights (i) deliver to IES, before the vote is taken,  written notice
of the shareholder's  intent to demand payment for shares of common stock if the
Proposed  Wisconsin  Transaction is consummated and (ii) not vote such shares of
capital stock in favor of the Mergers.  Any such notice by IES Shareholders must
be received by IES at IES Tower,  200 First  Street  S.E.,  Cedar  Rapids,  Iowa
52401, Attention: Vice President,  General Counsel and Secretary,  prior to such
vote. A vote against the Wisconsin  Merger Agreement will not satisfy the notice
requirement.  The submission by a shareholder of a blank proxy card or one voted
in favor of the Wisconsin Merger Agreement (if not revoked) will count as a vote
in favor of the Wisconsin Merger  Agreement and will serve to waive  dissenters'
rights.  However,  failure to return a proxy or to vote  against or abstain from
voting will not serve to waive such rights.

        Within ten days after the date on which the Wisconsin  Merger  Agreement
is approved by its shareholders,  IES must deliver a written  dissenters' notice
to all of its  shareholders  that have  given a written  notice and not voted in
favor of the  Wisconsin  Merger  Agreement  in  accordance  with  the  preceding
paragraph.  The dissenters'  notice will (i) state where the payment demand must
be sent and where and when  certificates  for  shares of  capital  stock must be
deposited,  (ii) supply a form for  demanding  payment that includes the date of
the first  announcement to the news media or to shareholders of the terms of the
Proposed Wisconsin Transaction and which requires that the shareholder asserting
dissenters' rights certify whether or not such shareholder  acquired  beneficial
ownership  of the shares  before  such date,  (iii) set a date by which IES must
receive the payment demand, which date will be not less than 30 nor more than 60
days from the date such dissenters' notice is delivered, and (iv) be accompanied
by the relevant sections of the IBCA.

        An IES  Shareholder  who has received a dissenters'  notice as described
above and who wishes to assert dissenters'  rights must demand payment,  certify
whether the shareholder  acquired beneficial  ownership of the shares before the
date  set  forth  in  the   dissenters'   notice  and  deposit  the  certificate
representing  the  shares in  accordance  with the terms of the  notice.  An IES
Shareholder who does not demand payment or deposit the IES  Shareholder's  share
certificates where required,  each by the date set in the dissenters' notice, is
not entitled to payment for the IES Shareholder's shares.

                                      -27-
<PAGE>


     Upon  receipt  of the  payment  demand,  or at the  effective  time  of the
Proposed Wisconsin Transaction,  whichever occurs later,  Interstate Energy must
pay each  dissenting  shareholder  that has complied with the  provisions of the
IBCA the amount estimated to be the fair value of the dissenter's  shares,  plus
accrued  interest from such effective time to the date of payment at the average
rate paid by Interstate  Energy on its bank loans or, if none, at a rate that is
fair and equitable under all the circumstances. Such payment must be accompanied
by certain  financial  data  relating to Interstate  Energy and other  specified
information  as required by the IBCA. If the Proposed  Wisconsin  Transaction is
not  effected  within  60 days  after  the date set for  demanding  payment  and
depositing  the  capital  share  certificates,  IES will  return  the  deposited
certificates  and,  if  the  Proposed  Wisconsin   Transaction  is  subsequently
effected,  Interstate  Energy will  deliver a new  dissenters'  notice as if the
corporate  action was taken without the vote of the  shareholders and repeat the
payment demand procedure. Interstate Energy may elect to withhold payment from a
dissenting  shareholder  unless the  dissenting  shareholder  was the beneficial
owner of the shares before the date set forth in the  dissenters'  notice as the
date  of  the  first  announcement  of  the  terms  of  the  Proposed  Wisconsin
Transaction.  If Interstate Energy so elects to withhold payment, it must, after
the  effective  time of the Proposed  Wisconsin  Transaction,  estimate the fair
value of the shares,  plus accrued interest at the rate described above, and pay
such amount and provide certain other specified  information as set forth in the
IBCA to each  such  dissenting  shareholder  who  agrees  to  accept  it in full
satisfaction of the dissenter's demand.

        According to the  IES/Interstate/WPL  Joint Proxy  Statement/Prospectus,
Shareholders  considering  seeking  dissenters'  rights should be aware that the
"fair value" of their IES Shares  determined  under  Sections  490.1301  through
490.1331  of the IBCA  could be more  than,  the same as or less than the market
value of such  securities  and that opinions of  investment  banking firms as to
fairness,  from a financial  point of view,  may not provide a reliable guide to
fair value  under  Sections  490.1301  through  490.1331.  If (i) the  dissenter
believes  that the  amount  offered  or paid is less than the fair  value of the
dissenter's  shares or that the interest  due is  incorrectly  calculated,  (ii)
Interstate  Energy fails to make  payment  within 60 days after the date set for
demanding payment,  or (iii) IES, having failed to effect the Proposed Wisconsin
Transactions,  does not return the deposited  certificates  within 60 days after
the date set for demanding  payment,  dissenters  may,  within 30 days after the
payment was made or offered,  notify  Interstate  Energy or IES, as the case may
be, in writing of the dissenting shareholder's own estimate of the fair value of
the shares and the amount of interest due, and demand  payment of the fair value
of such  shares and  interest  so  calculated  less  payments  received  by such
dissenting  shareholder,  if any. A dissenter waives the right to demand payment
as described in this paragraph unless the dissenter  notifies  Interstate Energy
of the dissenter's demand within 30 days after Interstate Energy made or offered
payment for the dissenter's shares. If demand of a dissenter for payment remains
unsettled, Interstate Energy must (i) commence a proceeding in the Iowa District
Court for Linn County,  Iowa,  within 60 days after receiving the payment demand
to  determine  the fair value of the shares and accrued  interest or (ii) pay to
each such dissenter the amount  demanded.  The costs of a proceeding,  including
the reasonable  compensation and expenses of appraisers  appointed by the court,
will generally be assessed against  Interstate  Energy.  The court may, however,
assess such court costs, including the fees and expenses of counsel and experts,
against  a  dissenter  that is found by the  court  to have  acted  arbitrarily,
vexatiously or not in good faith in demanding payment.

                               OWNERSHIP OF SHARES

        According to the  IES/Interstate/WPL  Joint Proxy  Statement/Prospectus,
(i) each Share is entitled to one vote on the Wisconsin Merger Agreement and the
Proposed  Wisconsin  Transaction,  (ii) as of the Record  Date,  29,923,233  IES
Shares were  outstanding,  (iii) the affirmative vote of a majority of the votes
entitled  to be cast by the  holders of IES Shares  represented  in person or by
proxy at the Annual Meeting entitled to vote thereon is required for approval of
the Wisconsin Merger Agreement and the Proposed Wisconsin Transaction,  and (iv)
the  

                                      -28-

<PAGE>


affirmative  vote of a  majority  of the votes  entitled  to be cast by the
holders of IES Shares  represented  in person or by proxy at the Annual  Meeting
and entitled to vote thereon is required for the election of directors.

        According to the  IES/Interstate/WPL  Joint Proxy  Statement/Prospectus,
proposals  of IES  Shareholders  intended to be presented at the 1997 IES Annual
Meeting  must be  received  at IES'  Corporate  Secretary's  Office on or before
November 20, 1996 for  consideration  for  inclusion in the proxy  statement and
form of proxy relating to that meeting.

        For  information  relating to the ownership of IES Shares by each person
known  to own 5% or  more  of the  outstanding  IES  Shares  and by the  current
directors and executive officers of IES, see Annex C hereto.

        The information  concerning IES and the Proposed  Wisconsin  Transaction
contained in this Proxy Statement (including Annex C hereto) has been taken from
or is based upon  documents and records on file with the Securities and Exchange
Commission  and  other  publicly  available  information.   MidAmerican  has  no
knowledge that would indicate that statements  relating to IES contained in this
Preliminary Proxy Statement in reliance upon publicly available  information are
inaccurate or incomplete. MidAmerican, however, has not been given access to the
books  and  records  of  IES,  was  not  involved  in the  preparation  of  such
information  and  statements,  and is not in a position  to verify,  or make any
representation  with  respect  to the  accuracy  of,  any  such  information  or
statements.

        The  IES/Interstate/WPL   Joint  Proxy   Statement/Prospectus   contains
additional  information  concerning the IES Shares,  beneficial ownership of the
IES Shares by, and other  information  concerning,  IES' directors and officers,
compensation  paid to  executive  officers,  and the  principal  holders  of IES
Shares.


                             SOLICITATION OF PROXIES

        Proxies  will  be  solicited  by  mail,  telephone,   telegraph,  telex,
telecopier  and other  electronic  means  and by  advertisement  and in  person.
Solicitation   may  be  made  by   directors,   executive   officers  and  other
representatives  of  MidAmerican.  See  Annex A  hereto  for a  listing  of such
persons.

     The entire expense of MidAmerican's  solicitation of proxies for the Annual
Meeting is being borne by MidAmerican. MidAmerican has retained D.F. King & Co.,
Inc.  ("D.F.  King") to assist and to provide  advisory  and proxy  solicitation
services in connection with this Proxy  Solicitation for which D.F. King will be
paid a  customary  fee of not more  than  $_______  and will be  reimbursed  for
reasonable  out-of-pocket  expenses.  D.F. King will utilize  approximately  100
individuals in the solicitation of proxies. MidAmerican will indemnify D.F. King
and Georgeson  against  certain  liabilities and expenses in connection with the
Proxy Solicitation, including liabilities under the federal securities law.

        Banks,  brokerage houses and other custodians,  nominees and fiduciaries
will be requested to forward the solicitation materials to the beneficial owners
of Shares for which they hold of record, and MidAmerican will reimburse them for
their reasonable out-of-pocket expenses.

        Pursuant to a letter  agreement  dated  August 2, 1996,  as amended (the
"Letter Agreement"), Dillon Read & Co. Inc. ("Dillon Read") is providing certain
financial  advisory  services to  MidAmerican  in  connection  with the proposed
MidAmerican  Merger.  Under the Letter Agreement,  MidAmerican has agreed to pay
Dillon Read for its financial  advisory services in connection with the proposed
MidAmerican  Merger a financial  advisory fee of 

                                      -29-

<PAGE>


     (i) $500,000 upon execution of the Letter  Agreement,  (ii) $1,000,000 upon
the public  announcement  of a proposal by  MidAmerican  to acquire  IES,  (iii)
$500,000  on the  six  month  anniversary  of the  Letter  Agreement,  and  (iv)
$5,160,000  less any fees  paid  pursuant  to (i),  (ii) and (iii)  above,  upon
consummation of an acquisition of IES.  MidAmerican has also agreed to reimburse
Dillon Read for its reasonable  out-of-pocket  expenses,  including the fees and
expenses of its legal counsel  incurred in connection with its  engagement,  and
has agreed to  indemnify  each of Dillon  Read and certain  related  persons and
entities  against  certain  liabilities  and expenses in connection  with Dillon
Read's  engagement,  including certain  liabilities under the federal securities
laws.  In  connection  with  Dillon  Read's  engagement  as  financial  advisor,
MidAmerican anticipates that certain employees of Dillon Read may communicate in
person, by telephone or otherwise with a limited number of institutions, brokers
or other  persons who are IES  Shareholders  for the purpose of assisting in the
Proxy  Solicitation.  Dillon Read will not receive any fee for or in  connection
with such  solicitation  activities by its  employees  apart from the fees it is
otherwise  entitled to receive as described  above.  Dillon Read has in the past
rendered and is currently  rendering  various  investment  banking and financial
advisory  services for  MidAmerican,  for which it has received and will receive
customary compensation.

     The  expenses  related  to  the  Proxy   Solicitation   will  be  borne  by
MidAmerican.  MidAmerican has not determined  whether to seek reimbursement from
IES of its expenses related to the Proxy Solicitation.

        If you have any  questions  concerning  this Proxy  Solicitation  or the
procedures  to be followed to execute and deliver a proxy,  please  contact D.F.
King at the address or phone number specified below.

         CERTAIN EMPLOYEES AND OTHER REPRESENTATIVES OF MIDAMERICAN WHO
               MAY ALSO SOLICIT PROXIES, AND CERTAIN TRANSACTIONS
                           BETWEEN ANY OF THEM AND IES


        As of the date of this Preliminary  Proxy Statement,  MidAmerican has no
security holdings in IES. Regina Rae Huggins, a person who will solicit proxies,

any beneficial ownership. Leonard L. Woodruff is the beneficial owner of 100 IES
Shares.  Jackie A. Fulhart owns 305 IES Shares.  Chris M. Swanson's wife owns 12
IES Shares.

     Other than as set forth  above,  as of the date of this  Preliminary  Proxy
Statement,  neither MidAmerican nor any of its directors,  executive officers or
other  representatives  or employees of  MidAmerican,  or other persons known to
MidAmerican,  who may solicit  proxies has any  security  holdings in IES except

the security holdings of IES, if any, of Paul A. Bjork, Marv E. Kingery,  Ginger
A. Dasso, Bob L. Lester,  Chuck H. Golliher,  Sally A. Robinson,  Kim K. Koster,
Chuck R. Montgomery, Steve R. Weiss, or John J. Cappello.  MidAmerican disclaims
beneficial  ownership  of any  securities  of IES  held by any  pension  plan of
MidAmerican or by any affiliate of MidAmerican.

        Dillon  Read  &  Co.  Inc.  ("Dillon  Read"),   financial   advisors  to
MidAmerican, does not admit that it or any of its directors, officers, employees
or affiliates are a "participant," as defined in Schedule 14A under the Exchange
Act, or that such Schedule 14A requires the  disclosure  of certain  information
concerning Dillon Read, Ken Crews, James Hunt, Jeff Miller,  Jason Sweet, Forest
Williams,  Jim Brandi, and Elliot Merrill,  in each case of Dillon Read, who may
assist  MidAmerican in such a solicitation.  Dillon Read engages in a full range
of investment banking, securities trading,  market-making and brokerage services
for  institutional  and  individual  clients.  In the  normal  course  of  their
business,  Dillon Read may trade  securities  of IES for its own account and the
account of its customers and, accordingly,  may at any time hold a long or short
position in such securities. As of the most recent practicable date prior to the
date  hereof as such  information  was  available,  Dillon Read did not hold any
securities of IES.

        Except as disclosed  above,  to the  knowledge of  MidAmerican,  none of
MidAmerican, the directors or executive officers of MidAmerican or the employees
or other representatives of MidAmerican named above has any interest,  direct or
indirect, by security holdings or otherwise, in IES.
