                            An Important Message For
                           IES Industries Shareholders

                             Maximize Your Dividend

You are  currently  being asked to vote on a merger of IES  Industries  with WPL
Holdings,  Inc. and Interstate  Power Company (the  "Wisconsin  deal").  If that
merger is  approved,  you will be  deprived  of the  opportunity  to receive the
higher dividend being proposed in the MidAmerican transaction.

                  Which Dividend Check Do You Want to Receive?
                              The Choice is Yours.

What IES Wants To Send You:

                     ratio of 2.346 share of MidAmerican common stock for
                     each share of IES common stock.

                A Leading Financial Analyst Has Made His Choice.

Edward Tirello,  Jr., a respected utility industry financial analyst for NatWest
Securities Corp., has made clear his recommendation  against the Wisconsin deal.
In a report to investors, he wrote:

"IES has provided no compelling reasons for its rejection of the MEC offer.....
We recommend that shareholders vote against the WPH proposal and in favor of
MEC's proposal." 

                            -------------------------

To support the  MidAmerican  proposal,  check the "Against" box, then sign, date
and mail your BLUE  proxy  today.  We urge you NOT to return  any green or white
proxy sent to you by IES. If you have already  returned your IES proxy,  you can
still change your vote. Only the latest-dated  proxy will count.  Time is short,
so please act today.

                       Don't Settle for a Lower Dividend.
                        Vote AGAINST the Wisconsin Deal.

TIME IS SHORT - VOTE BY PHONE TODAY                              August 27, 1996

DEAR IES SHAREHOLDER:

         You are now voting on an issue that is  critical  to the future of your
investment in IES  Industries.  As you know, an alternative  merger proposal has
been offered to IES by MidAmerican Energy, the largest,  fastest-growing utility
company in Iowa,  with 635,000  electric and 600,000  natural gas customers.  We
believe the  MidAmerican  proposal to merge with IES is better in every way than
the proposed merger of IES with WPL Holdings,  Inc. and Interstate Power Company
(the "Wisconsin deal"). WE URGE YOU TO VOTE AGAINST THE WISCONSIN DEAL.

         Don't be  swayed  by IES'  attempts  to  distract  you  from an  honest
comparison of the  MidAmerican  proposal and the Wisconsin deal. We believe that
IES doesn't want you to focus on what we believe are the  superior  fundamentals
of our proposal. To vote, or change your vote, see instructions below.

                               LOOK AT THE FACTS

     FACT:  HIGHER  VALUE.  The  MidAmerican  proposal  to  merge  with  IES
            Industries  provides you two options, an exchange of stock for 2.346
            MidAmerican shares  for each IES share (a $37.83  value  based on
            August  23,  1996  closing prices) or $39.00 per share in cash.* In
            contrast,  the proposed  Wisconsin deal offers a value of only
            $34.91 per IES share, based upon a 1.14 exchange ratio at August 23,
            1996 closing stock prices.

     FACT:  CHOICE.  Shareholders can receive all stock if they choose, or
            exchange their shares for cash.*

     * If holders of more than 40% of the total IES shares choose to receive
cash,  then all  shareholders  who elected to receive all cash will  receive the
same combination of cash and stock.  If you get a combination of cash and stock,
the stock portion will be entirely tax-free.

<PAGE>

     FACT:  TAX-FREE OPTION.  Shareholders who exchange IES shares for
            MidAmerican stock will receive new MidAmerican shares in a tax-free
            exchange.

     FACT:  HIGHER  DIVIDEND.  The  MidAmerican  proposal  offers  an annual
            dividend of $2.82 per IES Share - 25% higher than the $2.25 you
            would receive in the Wisconsin deal.  (Of course,  if you elect to
            receive cash for your shares, you will not continue to receive
            dividends).  In fact, until MidAmerican made its offer, the
            Wisconsin deal included a dividend cut for IES shareholders.

     FACT:  SECURE DIVIDEND.  For the twelve months ending June 30, 1996,
            MidAmerican's earnings exceeded its dividend by more than 18%.
            What's more, the savings we expect from a MidAmerican-IES merger
            will more than offset the cost of any new debt we may take on to
            accomplish that merger.

     FACT:  FINANCIALLY STRONG COMPANY.  MidAmerican Energy has "A+" credit 
            rating from Standard & Poor's.  That's higher than IES' current S&P
            rating.  Furthermore, we intend to pay down debt after the merger.
            MidAmerican has over $800 million in non-core assets that we're
            looking to redeploy into core energy and communications businesses,
            including the proposed merger with IES.

     FACT:  RAPID TRANSACTION CLOSING.  In the last five years, MidAmerican has
            completed two similar mergers in less than twelve months, and we
            believe this transaction can be completed in the same time frame.
            In fact, MidAmerican has already filed its approval application with
            the Federal Energy Regulatory Commission.  MidAmerican strongly
            believes that we can complete this transaction as soon as IES and
            the other parties can complete the Wisconsin deal - if not earlier.

     FACT:  CLEAR STRATEGY.  MidAmerican intends to become a major regional
            energy and communications company.  The fact that the combined
            MidAmerican/IES would have a combined 41% holding in McLeod, Inc.,
            a $1.2 billion publicly-traded telecommunications company, is
            evidence of our intent.

Exhibit 99(cc)

[Letter to Registered holders of IES shares]

[MidAmerican Energy letterhead]

August 27, 1996

Dear IES Shareholder:

         You are now voting on an issue that is  critical  to the future of your
investment in IES  Industries.  As you know, an alternative  merger proposal has
been offered to IES by MidAmerican Energy, the largest,  fastest-growing utility
company in Iowa,  with 635,000  electric and 600,000  natural gas customers.  We
believe the  MidAmerican  proposal to merge with IES is better in every way than
the proposed merger of IES with WPL Holdings,  Inc. and Interstate Power Company
(the "Wisconsin deal"). We urge you to vote against the Wisconsin deal.

         Don't be  swayed  by IES'  attempts  to  distract  you  from an  honest
comparison of the  MidAmerican  proposal and the Wisconsin deal. We believe that
IES doesn't want you to focus on what we believe are the  superior  fundamentals
of our proposal.

                               LOOK AT THE FACTS

FACT:  Higher  Value.  The  MidAmerican  proposal  to  merge  with  IES
       Industries  provides you two options, an exchange of stock for 2.346
       MidAmerican shares for each IES share (a $37.83 value based on August 23,
       1996 closing prices) or $39.00 per share in cash.* In contrast,  the
       proposed Wisconsin deal offers a value of only $34.91 per IES share,
       based upon a 1.14 exchange ratio at August 23, 1996 closing stock prices.

FACT:  Choice.  Shareholders can receive all stock if they choose, or exchange
       their shares for cash.*

FACT:  Tax-Free Option.  Shareholders who exchange IES shares for MidAmerican
       stock will receive new MidAmerican shares in a tax-free exchange.

FACT:  Higher  Dividend.  The  MidAmerican  proposal  offers  an annual dividend
       of $2.82 per IES Share - 25% higher than the $2.25 you would receive in
       the Wisconsin deal.  (Of course, if you elect to receive cash for your
       shares, you will not continue to receive dividends).  In fact, until
       MidAmerican made its offer, the Wisconsin deal included a dividend cut
       for IES shareholders.

FACT:  Secure Dividend.  For the twelve months ending June 30, 1996,
       MidAmerican's earnings exceeded its dividend by more than 18%.  What's
       more, the savings we expect from a MidAmerican-IES merger will more than
       offset the cost of any new debt we may take on to accomplish that merger.

* If holders of more than 40% of the total IES  shares  choose to receive  cash,
then all  shareholders  who  elected to receive  all cash will  receive the same
combination of cash and stock.  If you get a combination of cash and stock,  the
stock portion will be entirely tax-free.

<PAGE>

FACT:  Financially  Strong Company.  MidAmerican Energy has "A+" credit rating
       from Standard & Poor's.  That's higher than IES' current S&P rating.
       Furthermore,  we intend to pay down debt after the merger.  MidAmerican
       has over $800 million in non-core assets that we're looking to redeploy
       into core energy and communications businesses, including the proposed
       merger with IES.

FACT:  Rapid Transaction Closing.  In the last five years, MidAmerican has
       completed two similar mergers in less than twelve months, and we believe
       this transaction can be completed in the same time frame.  In fact,
       MidAmerican has already filed its approval application with the Federal
       Energy Regulatory Commission.  MidAmerican strongly believes that we can
       complete this transaction as early as the Wisconsin deal-if not earlier.

FACT:  Clear Strategy.  MidAmerican intends to become a major regional energy
       and communications company.  The fact that the combined MidAmerican/IES
       would have a combined 41% holding in McLeod, Inc., a $1.2 billion
       publicly-traded telecommunications company, is evidence of our intent.

            VOTE AGAINST THE WISCONSIN DEAL - TIME IS OF THE ESSENCE
                           The MidAmerican Proposal:
                                  Better Value
                                Better Dividend
                                Better Strategy

To support the  MidAmerican  proposal,  check the "Against" box, then sign, date
and mail the enclosed  BLUE proxy today.  We urge you NOT to return any green or
white proxy sent to you by IES. If you have already returned your IES proxy, you
can still change your vote. Only the latest-dated  proxy will count.  Time is of
the essence, so please act today.

Sincerely,


RUSSELL E. CHRISTIANSEN                   STANLEY J. BRIGHT

         FOR THE  INFORMATION OF IES  SHAREHOLDERS:  Please be advised that each
proxy card that you have  received or will  receive from  MidAmerican  is a card

each of the following  Company Plans:  the IES Dividend  Reinvestment  and Stock
Purchase  Plan,  IES  Employee  Stock  Purchase  Plan,  and the IES Bonus  Stock
Ownership Plan, if any.

         MidAmerican  has filed with the  Securities  and Exchange  Commission a

[Newspaper advertisement appearing in the August 27, 1996 Wall Street Journal]

                            An Important Message For
                           IES Industries Shareholders

                                  Time Is Money

                     Our  FERC  Filing  Brings  Us Neck  And Neck In The Race To
                    Obtain Regulatory Approval.

Don't be swayed by IES'  attempts to distract you from an honest  comparison  of
the  MidAmerican  proposal and the Wisconsin  deal. The regulatory  structure of
MidAmerican's  merger proposal closely resembles its two previous mergers,  each
of which was completed in less than 12 months.  We are confident we can complete
a merger with IES within that same time frame after signing a definitive  merger
agreement.

We Believe A MidAmerican/IES Merger Could Be Completed In Less Than 12 Months

The sooner a merger is completed, the sooner you can get your MidAmerican shares
(with a 25% higher dividend) or $39 per share in cash. The MidAmerican  proposal
could be completed as early as the Wisconsin deal--if not earlier. The Wisconsin
deal is a complex three-way,  four-state transaction that requires approval from
more regulatory bodies than the MidAmerican proposal.  Plus, the three companies
in the Wisconsin deal lack direct  transmission  interconnection.  The Wisconsin
deal was announced in November,  1996,  more than nine months ago, and they have
yet to receive approval from a single regulatory agency. Meanwhile, only 21 days
after announcing our merger proposal,  we have already filed an application with
the Federal  Energy  Regulatory  Commission  (FERC) for approval of our proposed
merger.

Compare the regulatory approvals each transaction needs:

     The Wisconsin Deal Needs:                  MidAmerican's Proposal Needs:
*Federal Energy Regulatory Commission      *Federal Energy Regulatory Commission
*Iowa Utilities Board                      *Iowa Utilities Board
*Illinois Commerce Commission              *Illinois Commerce Commission
*Nuclear Regulatory Commission             *Nuclear Regulatory Commission
*Wisconsin Public Services Commission
*Minnesota Public Utilities Commission
*Securities and Exchange Commission

But don't  just take our word for it.  Read what  George  Bruder,  a  recognized
expert in FERC  proceedings  and a former  President  of the Federal  Energy Bar
Association,  wrote in an August 25, 1996 letter to IES  shareholders  (the full
text of Mr. Bruder's letter is available by calling 1- 888-776-4692).*

         "I find  no  basis  on  which  to  conclude  that  the  Federal  Energy
Regulatory  Commission is more likely to consider and decide either  application
earlier than the other  application,  and I conclude  that the two  applications
likely will be decided in the same time frame."


<PAGE>


                                Still More Value

We  believe   MidAmerican's   proposal   still   provides  more  value  for  IES
shareholders. Our proposal offers you a dividend 25% higher than the dividend in
the Wisconsin  deal.  Only our proposal would give you $3.39 more per IES share,
based on closing  stock prices on August 23, 1996.  And only our proposal  would
give you an  optional  cash  election  worth $39 per IES  share.  The  choice is
yours.**

ATTENTION PROFESSIONAL INVESTMENT COMMUNITY:

MUST READING BEFORE ADVISING CLIENTS WHO HOLD IES STOCK!!!

* Higher Value - The MidAmerican  proposal to merge with IES Industries provides
IES shareholders  with two options:  an exchange of stock for 2.346  MidAmerican
shares for each IES share (a $37.83  value based on 8/23/96  closing  prices) or
$39.00 per share in cash.** In contrast,  the proposed  Wisconsin  deal offers a
value of only $34.91 per IES share,  based upon a 1.14 exchange ratio at 8/23/96
closing stock prices.

* Choice - Shareholders can  receive all stock if they choose, or exchange their
shares for cash.**

* Tax-Free Option - Shareholders  who exchange IES shares for MidAmerican  stock
will receive new MidAmerican share in a tax-free exchange.

* Higher Dividend - The MidAmerican  proposal offers an annual dividend of $2.82
per IES share - 25% higher  than the $2.25 a  shareholder  would  receive in the
Wisconsin  deal. (Of course,  if you elect to receive cash for your shares,  you
will not continue to receive  dividends.) In fact,  until  MidAmerican  made its
offer, the Wisconsin deal included a dividend cut for IES shareholders.

* Secure  Dividend - For the twelve months  ending June 30, 1996,  MidAmerican's
earnings  exceeded  its dividend by more than 18%.  What's more,  the savings we
expect from a  MidAmerican-IES  Merger will more than offset the cost of nay new
debt we may take on to accomplish that merger.

* Financially Strong Company - MidAmerican Energy has an "A+" credit rating from
Standard & Poor's. That's higher than IES' current S&P rating.  Furthermore,  we
intend to pay down debt after the merger.  MidAmerican  has over $800 million in
non-core   assets  that  we're   looking  to  redeploy   into  core  energy  and
communications businesses, including the proposed merger with IES.

* Rapid Transaction Closing - In the last five years,  MidAmerican has completed
two similar mergers in less than twelve months,  and we believe this transaction
can be completed in the same time frame. In fact,  MidAmerican has already filed
its  approval  application  with  the  Federal  Energy  Regulatory   Commission.
MidAmerican  strongly  believes that we can complete this transaction as soon as
IES and the other parties can complete the Wisconsin deal - if not earlier.

     ** If holders  or more than 40% of the total IES  shares  choose to receive
cash,  then all  shareholders  who elected to receive all cash will  receive the
same  combination of cash and stock. If a shareholder gets a combination of cash
and stock, the stock portion will be entirely tax-free.

* Clear  Strategy - MidAmerican  intends to become a major  regional  energy and
communications company. The fact that the combined  MidAmerican/IES would have a
combined  41%  holding  in  McLeod,   Inc.,   a  $1.2  billion   publicly-traded
telecommunications company, is evidence of our intent.

ANOTHER HOSTILE ATTEMPT

* IES  Rejects  MEC's  Proposal.  On August 16,  1996,  MEC  announced  that IES
Industries   (IES-$33  7/8-NF)  has  rejected  its  merger  proposal  valued  at
approximately  $1.17  billion.  On August 5, 1996,  MEC had announced a proposed
merger  with  IES in a cash  and  stock  transaction  which  would  provide  IES
shareholders  with a  significant  premium  over the  consideration  they  would
receive in a proposed  merger with WPL Holdings  (WPH-$31  5/8-H) and Interstate
Power (IPW-$31 3/8-NF).  Under the MEC proposal,  IES shareholders would receive
$37.24  per  IES  share  based  on  MEC's  closing  price  on  8/15/96,  and the
opportunity , as a whole,  to receive $39 per share in cash for up to 40% of the
outstanding  IES shares.  Under the WPH deal,  IES  shareholders  would received
$36.20 per IES share based on the WPH closing  price on  8/15/96.  In  addition,
MEC's merger  proposal  would provide IES  shareholders  with a $2.82  dividend,
based on the exchange  ratio of 2.346 IES shares per MEC share and MEC's current
annual  dividend of $1.20 per share,  in contrast to a $2.25  dividend under the
Wisconsin deal assuming that WPH maintains its current dividend policy.

* MEC is Not Giving Up. IES has provided no compelling reasons for its rejection
of the MEC offer.  MEC is  committed  to its merger  proposal  and will  solicit
proxies from IES  shareholders  urging them to reject the  Wisconsin  deal.  The
offer,  which is  contingent  upon  receipt of all  necessary  approvals  (i.e.,
shareholders, Iowa and Illinois commissions, FERC, SEC, Hart-Scott-Rodino), will
provide  more than  $500  million  in cost  savings  during  the first ten years
following  consummation.   It  is  anticipated  that  all  necessary  regulatory
approvals  can be obtained  within 12 months  after  execution  of a  definitive
merger agreement.

* Our Recommendation:  Vote For the MEC/IES Combination. While on the surface it
appears that the proposed merger with MEC and IES would provide greater benefits
for IES  shareholders than the transaction with WPH., we have adopted a position
of cautious  support  given the high  payout (80% by the year 2000).  We believe
that a hostile takeover can be completed. On September 5, 1996, IES shareholders
are scheduled to vote on the  proposed  transaction  with WPH We recommend  that
shareholders vote against the WPH proposal and in favor of MEC's proposal. A 50%
majority vote of outstanding shares is required for approval of the transaction.

IMPORTANT DEVELOPMENT

The following important development was today reported as a news release:

               NATWEST SECURITIES RECOMMENDS THAT IES INDUSTRIES
                  SHAREHOLDERS VOTE AGAINST THE WISCONSIN DEAL

     Des  Moines,  Iowa  (August  26,  1996)  -  NatWest  Securities  Corp.  has
recommended to  shareholders  of IES Industries  Inc.  (NYSE:IES) that they vote
against the proposed merger with WPL Holdings, Inc. and Interstate Power Company
(the "Wisconsin  deal").  NatWest also recommends that IES shareholders  support
the alternative merger proposed by MidAmerican Energy Company (NYSE:MEC). Edward
Tirello, Jr., a respected utility industry analyst for NatWest Securities, wrote
in his report:  "IES has provided no compelling reasons for its rejection of the
MEC offer . . . . We recommend that  shareholders  vote against the WPH proposal
and in favor of MEC's proposal."

We believe this  important  development  may assist you in reaching  your voting
decision.

MidAmerican  has filed  with the  Securities  and  Exchange  Commission  a proxy
statement and other  materials  relating to the  solicitation of proxies against
the proposed  IES/WPL/Interstate  transaction  and that proxy  statement and the
other materials are incorporated herein by reference.

[Newspaper advertisement published in Iowa newspapers on August 27, 1996]

********************************************************************************
                            Here are some plain-truth
                              facts that IES hopes
                                  you'll ignore
********************************************************************************
             In a desperate effort to keep their Wisconsin deal from
         coming apart, IES is attacking MidAmerican Energy Company. Yet
                          no matter how hard they try, they can't overcome these
           facts about our merger proposal:

1        Our dividend is better.
MidAmerican's  proposal would pay IES  shareholders  $2.82 per current IES share
vs.  only $2.25 in the  Wisconsin  deal.*  That's a 25%  difference,  yet IES is
hoping you'll overlook this fact and accept a lower dividend for your shares.
Who's kidding whom?
         And,  even if IES were able to grow their  future  dividends  by 1% per
year,  as suggested by a Wisconsin  analyst,  they wouldn't be able to match the
$2.82 dividend MidAmerican is offering now...for 23 years!

2        Our dividend is secure.
For the twelve months ending June 30, 1996,  MidAmerican's earnings exceeded its
dividend by more than 18%!
         What's more, the savings we expect from a  MidAmerican-IES  merger will
more  than  offset  the cost of any new debt we may take on to  accomplish  that
merger.

3        We are financially sound.
MidAmerican  Energy has an A+ rating from Standard & Poor's.  That's higher than
IES' current S&P rating.
         We intend  to pay down debt  after  the  merger.  MidAmerican  has $800
million in non-  utility  assets  that we're  looking to redeploy  into  utility
service and communications businesses, including the proposed merger with IES.

            The bottom line is this. MidAmerican Energy is a strong,
           Iowa-based company, with a proposal that offers more to IES
                  shareholders.  Yet IES hopes  you'll  ignore the facts so they
             can push ahead with their Wisconsin deal.
         It's your choice...the higher-value MidAmerican proposal or the
    less-for-your-money Wisconsin deal. Your vote will help determine which
                              direction IES takes.

[Newspaper Advertisement Published in Iowa Newspapers on August 27, 1996]

                             Here are some questions
                                IES shareholders
                                should be asking

IES hasn't  told its  shareholders  the whole  story  about the  Wisconsin  deal
they're trying to push through. If you're an IES shareholder, you should ask for
answers to these questions:

1. Why didn't IES tell its  shareholders it had a better offer from  MidAmerican
Energy back in October 1995 before it agreed to sell out to a Wisconsin  company
at a price  considerably less than what the company is worth? Now, they're again
rejecting our superior offer.

2.  Why did the IES  Board  twice  vote for  deals  reducing  dividends  for IES
shareholders,  and only sweetened the deal when  MidAmerican came along with its
higher-value  proposal?  And if IES gets a go-ahead for the Wisconsin deal, what
will happen to your dividend then?

3. Why is IES glossing  over the  complexity  of the  Wisconsin  deal?  After 10
months, a corporate  structure has yet to be defined! Is the Wisconsin merger so
complex  that IES will have to become a  Wisconsin  corporation  and a Wisconsin
water utility?

4. Why does IES continue to reject  MidAmerican's  merger  proposal?  You should
also ask why the IES  Board of  Directors,  at a meeting  held  just last  week,
approved additional  increases to the "Golden Parachutes"  totaling $1.3 million
in salaries and benefits for certain IES executives?
Just whose money is that anyway?

Shareholders, don't let IES rush you into their Wisconsin deal without answering
these questions. Because the answers will affect you and your financial future.

                         Vote AGAINST the Wisconsin Deal
IES  shareholders  have been sent proxy  materials,  including a BLUE proxy,  by
MidAmerican Energy.  Check the "Against" box; sign, date and mail the BLUE proxy
