INDEPENDENT ACCOUNTANTS' REPORT


Board of Directors and Stockholders
MidAmerican Energy Holdings Company
Des Moines, Iowa

We have reviewed the  accompanying  consolidated  balance  sheet of  MidAmerican
Energy  Holdings  Company and  subsidiaries  as of September  30, 1999,  and the
related  consolidated  statements  of  operations  for the three and nine  month
periods  ended  September  30,  1999  and  1998  and  the  related  consolidated
statements of cash flows for the nine month periods ended September 30, 1999 and
1998.  These  financial  statements  are  the  responsibility  of the  Company's
management.

We conducted our review in accordance with standards established by the American
Institute  of  Certified  Public  Accountants.  A review  of  interim  financial
information consists principally of applying analytical  procedures to financial
data and of making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with  generally  accepted  auditing  standards,  the  objective  of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material  modifications that should
be made to such consolidated  financial  statements for them to be in conformity
with generally accepted accounting principles.

We have  previously  audited,  in accordance  with generally  accepted  auditing
standards, the consolidated balance sheet of MidAmerican Energy Holdings Company
and  subsidiaries  as  of  December  31,  1998,  and  the  related  consolidated
statements of operations, stockholders' equity, and cash flows for the year then
ended (not  presented  herein),  and in our report dated January 28, 1999 (March
12, 1999 as to Note 3 and Note 21), we expressed an unqualified opinion on those
consolidated financial statements.  In our opinion, the information set forth in
the  accompanying  consolidated  balance sheet as of December 31, 1998 is fairly
stated, in all material respects,  in relation to the consolidated balance sheet
from which it has been derived.

                       MIDAMERICAN ENERGY HOLDINGS COMPANY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   GENERAL:

In the  opinion of  management  of  MidAmerican  Energy  Holdings  Company  (the
"Company"), the accompanying unaudited consolidated financial statements contain
all adjustments  (consisting  only of normal  recurring  accruals)  necessary to
present  fairly the financial  position as of September 30, 1999 and the results
of operations  for the three and nine months ended  September 30, 1999 and 1998,
and cash  flows for the nine  months  ended  September  30,  1999 and 1998.  The
results of operations for the three and nine months ended September 30, 1999 and
1998 are not  necessarily  indicative of the results to be expected for the full
year.

The consolidated  financial  statements  include the accounts of the Company and
its wholly and majority  owned  subsidiaries.  Other  investments  and corporate
joint ventures,  including CE Generation  (defined herein) where the Company has
the ability to exercise significant influence are accounted for under the equity
method.  Investments,  where the Company's ability to influence is limited,  are
accounted for under the cost method of accounting.

Certain  amounts  in the  1998  financial  statements  and  supporting  footnote
disclosures  have been  reclassified to conform to the 1999  presentation.  Such
reclassification  did not impact  previously  reported  net  income or  retained
earnings.

Reference is made to the  Company's  most  recently  issued  annual  report that
included  information  necessary or useful to the understanding of the Company's
business and financial statement presentations.

2.   MIDAMERICAN MERGER:

On August 11, 1998,  the Company  entered  into an Agreement  and Plan of Merger
("MidAmerican  Merger")  with MHC Inc.,  formerly  MidAmerican  Energy  Holdings
Company ("MHC"). The MidAmerican Merger closed on March 12, 1999 and the Company
paid $27.15 in cash for each  outstanding  share of MHC common stock for a total
of  approximately  $2.42  billion  in a merger  pursuant  to which MHC became an
indirect  wholly  owned  subsidiary  of the Company.  Additionally,  the Company
reincorporated in the State of Iowa and was renamed  MidAmerican Energy Holdings
Company and upon closing became an exempt public utility holding company.

The  consummation  of the MidAmerican  Merger was conditioned  upon receipt of a
number of regulatory and  shareholder  approvals and the  disposition of partial
interests in certain of the Company's independent power generating facilities in
order to maintain  the  qualifying  facilities  status of such power  generating
facilities. See Note 3.

The MidAmerican Merger has been accounted for as a purchase business combination
and as such the results of operations of the Company  include the results of MHC
beginning  March 12,  1999.  The  purchase  price has been  allocated  to assets
acquired and liabilities assumed based on preliminary valuations and the Company
is awaiting final  valuations.  The Company  recorded  goodwill of approximately
$1.5 billion which is being  amortized  using the straight line method over a 40
year period.

On March 11, 1999,  MidAmerican  Funding,  LLC, a wholly owned subsidiary of the
Company,  issued  $200  million of 5.85%  Senior  Secured  Notes due 2001,  $175
million of 6.339%  Senior  Secured  Notes due 2009,  and $325  million of 6.927%
Senior  Secured  Bonds due 2029.  The proceeds  from the  offering  were used to
complete the MidAmerican Merger.

                                      -7-


Unaudited pro forma  combined  revenue,  income before  extraordinary  item, net
income and basic  earnings  per share of the Company and MHC for the nine months
ended  September  30, 1999 and 1998, as if the  acquisition  had occurred at the
beginning  of the year  after  giving  effect to certain  pro forma  adjustments
related to the  acquisitions,  including the sales of the qualified  facilities,
the issuance of senior  secured notes and bonds and the  redemptions  of certain
limited  recourse notes and senior  discount notes,  were $3.47 billion,  $164.4
million,  $124.3  million and $2.08,  respectively,  compared to $2.90  billion,
$81.4 million, $81.4 million and $1.35,  respectively,  for the same period last
year.

3.   QUALIFIED FACILITIES DISPOSITIONS:

The  consummation  of the MidAmerican  Merger was conditioned  upon receipt of a
number of regulatory approvals.  Regulatory approval required the disposition of
partial  interests  in certain of the  Company's  independent  power  generating
facilities  prior to the  consummation  of the  MidAmerican  Merger  in order to
maintain the qualifying  facilities status of such power generating  facilities.
To  accomplish  this  disposition,  the following  events  occurred in the first
quarter of 1999:

On February 8, 1999,  the Company  created a new  subsidiary,  CE Generation LLC
("CE  Generation")  and  subsequently  transferred its interest in the Company's
power  generation  assets  in the  Imperial  Valley  and  the Gas  Plants  to CE
Generation.

On  February  26,  1999,  the  Company  closed  the sale of all of its  indirect
ownership interests in the Coso Joint Ventures ("Coso") to Caithness Energy LLC.
The price includes $205 million in cash and $5 million in contingent payments.

On March 2,  1999,  CE  Generation  closed  the sale of $400  million  aggregate
principal amount of its 7.416% Senior Secured Bonds due 2018 and distributed the
proceeds to the Company.

On March 3, 1999, the Company closed the sale of 50% of its ownership  interests
in CE Generation to an affiliate of El Paso Energy  Corporation for an aggregate
consideration of approximately  $245 million in cash, $6.5 million in contingent
payments and $23.5 million in equity  commitments.  Including the gross proceeds
from  the  CE  Generation  debt  offering,   the  aggregate   consideration  was
approximately  $675  million.  Due to the  sale  of 50% of its  interests  in CE
Generation,  the Company has accounted for CE Generation as an equity investment
beginning March 3, 1999.

4.   EXTRAORDINARY ITEMS:

The remaining  outstanding  Senior  Discount  Notes were redeemed on January 15,
1999 at a redemption price of 105.125% plus accrued  interest.  Due to the early
extinguishment   of  the  Senior  Discount  Notes,   the  Company   recorded  an
extraordinary loss of approximately $14 million, net of tax.

On  January  29,  1999,  the  Company  commenced  a cash  offer  for  all of its
outstanding Limited Recourse Notes. The Company received tenders from holders of
an aggregate of approximately  $195.8 million principal which were paid on March
3, 1999,  at a redemption  price of 110.025% plus accrued  interest.  Due to the
early  retirement  of the  Limited  Recourse  Notes,  the  Company  recorded  an
extraordinary loss of approximately $17.5 million, net of tax.

The Company  redeemed $103.9 million in principal value of the 9.5% Senior Notes
at an  aggregate  price of $114.6  million  throughout  the first nine months of
1999.  Due to the early  extinguishment  of this debt,  the Company  recorded an
extraordinary loss of $8.5 million net of tax in the first nine months of 1999.

6.   COMMITMENTS AND CONTINGENCIES:

INDONESIA

On December 2, 1994,  subsidiaries of the Company,  Himpurna  California  Energy
Ltd. ("HCE") and Patuha Power,  Ltd. ("PPL",  together with HCE, the "Indonesian
Subsidiaries")  executed separate joint operation  contracts for the development
of geothermal steam fields and geothermal  power  facilities  located in Central
Java in  Indonesia  with  Perusahaan  Pertambangan  Minyak  Dan Gas Bumi  Negara
("Pertamina"),  the  Indonesian  national  oil company,  and  executed  separate
"take-or-pay"  energy sales contracts  ("ESCs") with both Pertamina and P.T. PLN
(Persero) ("PLN"),  the Indonesian national electric utility.  The Government of
Indonesia provided sovereign  performance  undertakings of the obligations under
the joint operating and "take-or-pay" contracts.

In 1997 and 1998 a series of  Indonesian  government  decrees and other  actions
(including  the  non-payment  of all monthly  invoices  from HCE's Dieng Unit I,
which became  operational in March 1998) created  significant  uncertainty as to
whether  PLN  and  the  Indonesian  government  would  honor  their  contractual
obligations to the Indonesian Subsidiaries.

On or about August 14, 1998, the Company,  through the Indonesian  Subsidiaries,
began arbitration proceedings against PLN in connection with the HCE's and PPL's
geothermal  power  projects  in  Indonesia,  the Dieng  Project  and the  Patuha
Project.  The arbitration  was conducted under the United Nations  Commission of
International  Trade Law  ("UNCITRAL")  rules.  In its  Statement of Claim,  HCE
alleged that PLN breached the "take-or-pay"  provisions of its ESA with HCE and,
through its conduct has  repudiated the ESC with HCE. In its Statement of Claim,
PPL  alleged  that,  in  conjunction  with PLN's  breach of the ESC with HCE and
through its conduct,  PLN

                                      -9-


repudiated  the ESC with PPL. On or about  December 10, 1998,  PLN delivered two
Statements of Defense in respect of the HCE claim and the PPL claim.

An arbitral  tribunal found that PLN had  materially  breached the provisions of
the Energy  Sales  Contracts  between PLN and both HCE and PPL,  and awarded HCE
$391,711,652  and  PPL  $180,570,322,  and  ordered  PLN  to pay  these  amounts
immediately.  Following PLN's failure to pay such amounts,  PPL and HCE demanded
payment  pursuant  to  the  sovereign  performance  undertakings  issued  by the
Minister of Finance  ("MOF") on behalf of the Republic of Indonesia  ("ROI") and
following the ROI's failure to pay brought an arbitration against the ROI for
breach of those undertakings.

A final  award  was  issued  by an  international  arbitration  panel in the ROI
arbitration on October 15, 1999 which found that:

     o The  ROI  is in  breach  of  its  performance  undertakings and  violated
       international law.

     o The ROI is required to pay HCE and PPL an aggregate amount of
       approximately $575 million.

The Company  carries  political  risk insurance on its investment in HCE and PPL
through  OPIC,  an agency of the U.S.  Government,  as well as  through  private
market insurers. Such insurance covers expropriation of the Company's investment
in HCE and PPL, as well as  material  breaches by PLN of the ESCs and by the ROI
of its  performance  undertakings.  The  Company  filed  claims in the amount of
approximately  $290 million  pursuant to such political risk insurance  policies
with OPIC and the private market insurers and intends to vigorously  pursue such
claims with OPIC and the private market insurers, if necessary.

NYSEG

On February 14, 1995,  New York State  Electric & Gas  ("NYSEG")  filed with the
Federal  Energy  Regulatory  Commission  ("FERC") a Petition  for a  Declaratory
Order,  Complaint,  and  Request  for  Modification  of Rates in Power  Purchase
Agreements  Imposed  Pursuant to the Public Utility  Regulatory  Policies Act of
1978  ("Petition")  seeking  FERC (i) to declare that the rates NYSEG pays under
the Saranac Power Purchase Agreement  ("Saranac PPA"), which was approved by the
New York Public  Service  Commission  (the  "PSC"),  were in excess of the level
permitted  under PURPA and (ii) to authorize  the PSC to reform the Saranac PPA.
On March 14, 1995,  the Saranac  Partnership  intervened  in  opposition  to the
Petition asserting,  inter alia, that the Saranac PPA fully complied with PURPA,
that NYSEG's  action was  untimely and that the FERC lacked  authority to modify
the Saranac PPA. On March 15, 1995, the Company intervened also in opposition to
the Petition and asserted  similar  arguments.  On April 12, 1995, the FERC by a
unanimous  (5-0)  decision  issued an order  denying the various forms of relief
requested  by NYSEG and finding  that the rates  required  under the Saranac PPA
were consistent with PURPA and the FERC's  regulations.  On May 11, 1995,  NYSEG
requested  rehearing of the order and, by order  issued July 19, 1995,  the FERC
unanimously (5-0) denied NYSEG's request. On June 14, 1995, NYSEG petitioned the
United States Court of Appeals for the District of Columbia  Circuit (the "Court
of Appeals")  for review of FERC's  April 12, 1995 order.  FERC moved to dismiss
NYSEG's  petition for review on July 28, 1995. On October 30, 1996,  all parties
filed final briefs and the Court of Appeals heard oral  arguments on December 2,
1996.  On July 11,  1997,  the Court of Appeals  dismissed  NYSEG's  appeal from
FERC's denial of the petition on jurisdictional grounds.

On August 7, 1997,  NYSEG filed a complaint in the U.S.  District  Court for the
Northern  District  of New York  against  the FERC,  the PSC (and the  Chairman,
Deputy  Chairman  and the  Commissioners  of the  PSC as  individuals  in  their
official capacity), the Saranac Partnership and Lockport Energy Associates, L.P.
("Lockport")  concerning the power purchase  agreements  that NYSEG entered into
with Saranac  Partners and  Lockport.  NYSEG's suit asserts that the PSC and the
FERC improperly  implemented  PURPA in authorizing the pricing terms that NYSEG,
the Saranac  Partnership and Lockport agreed to in those  contracts.  The action
raises  similar legal  arguments to those  rejected by the FERC in its April and
July 1995 orders.  NYSEG in addition  asks for  retroactive  reformation  of the
contracts  as of the date of  commercial  operation  and  seeks a refund of $281
million

                                      -10-

from the Saranac  Partnership.  The Saranac  Partnership  and other parties have
filed motions to dismiss and oral arguments on those motions were heard on March
2, 1998 and again on March 3, 1999. The Court's decision is pending. The Saranac
Partnership  believes that NYSEG's claims are without merit for the same reasons
described in the FERC's orders.

COOPER LITIGATION

On July 23, 1997, Nebraska Public Power District ("NPPD") filed a Complaint,  in
the  United  States  District  Court  for  the  District  of  Nebraska,   naming
MidAmerican Energy Company ("MEC"), an indirectly wholly owned subsidiary of the
Company,  as the defendant and seeking  declaratory  judgment as to three issues
under the parties' long-term power purchase agreement for Cooper Nuclear Station
("Cooper")  capacity and energy.  More  specifically,  NPPD seeks a  declaratory
judgment in the following respects:  (1) that MEC is obligated to pay 50% of all
costs and expenses associated with decommissioning Cooper, and that in the event
NPPD  continues  to  operate  Cooper  after  expiration  of the  power  purchase
agreement  (September  2004),  MEC  is  not  entitled  to  reimbursement  of any
decommissioning  funds it has paid to date or will pay in the  future;  (2) that
the  current   method  of  allocating   transition   costs  as  a  part  of  the
decommissioning cost is proper under the power purchase agreement;  and (3) that
the current method of investing  decommissioning funds is proper under the power
purchase agreement.

MEC filed its answer and contingent counterclaims.  The contingent counterclaims
filed by MEC are generally as follows:  (1) that MEC has no duty under the power
purchase agreement to reimburse or pay 50% of the  decommissioning  costs unless
certain  conditions  occur; (2) that NPPD has the duty to repay all amounts that
MEC has prefunded for decommissioning in the event NPPD operates the plant after
the term of the power purchase  agreement;  (3) that NPPD is equitably  estopped
from  continuing  to  operate  the plant  after  the term of the power  purchase
agreement; (4) that NPPD has granted MEC an option to continue taking 50% of the
power from the plant;  (5) that the term "monthly power costs" as defined in the
power  purchase  agreement does not include costs and expenses  associated  with
decommissioning the plant; (6) that MEC has no duty to pay for nuclear fuel, O&M
projects or capital  improvements  that have useful  lives after the term of the
power  purchase  agreement;  (7) that  transition  costs are not included in any
decommissioning  costs and expenses;  (8) that NPPD has breached its duty to MEC
in making  investments of certain funds;  (9) that reserves in certain  accounts
are  excessive and should be refunded to MEC; and (10) that NPPD must credit MEC
for certain payments by MEC for low-level radioactive waste disposal.

On  October  6,  1999,  the  Court  rendered  summary  judgment  for NPPD on the
above-mentioned issue concerning liability for decommissioning (issue one in the
first paragraph  above) and the related  contingent  counterclaims  filed by MEC
(issues one, two, three and five in the second paragraph  above). On November 3,
1999 the Court  referred  all  remaining  issues in the case to  mediation,  and
cancelled  the November  1999 trial date.  MEC filed its appeal with the Federal
Court of Appeals for the Eighth Circuit of the Court's  summary judgment ruling.
MEC will participate in mediation in an attempt to resolve the remaining issues.

7.   SUBSEQUENT EVENTS:

On October 14, 1999, the Company announced that  HomeServices.Com,  a subsidiary
of the Company, closed its initial public offering of 3,250,000 shares of common
stock at $15 per share.  HomeServices sold 2,187,500 shares and the Company, the
selling stockholder, sold 1,062,500 shares in the offering.  HomeServices.Com is
the  surviving  entity of a merger with  MidAmerican  Realty  Services.  The net
proceeds  received  by it in the  offering  will be used for  general  corporate
purposes,   which  are  expected  to  include  acquisitions  and  the  continued
development of its E-commerce operations.

On October 24, 1999,  the Company and entities  representing  an investor  group
comprised of Berkshire Hathaway Inc. ("Berkshire Hathaway"),  Walter Scott, Jr.,
the current  chairman  of Level 3  Communications,  Inc.  and a director of the
Company,  and David L.  Sokol,  Chairman  and  Chief  Executive  Officer  of the
Company,  executed a definitive


                                     -11-


agreement and plan of merger whereby the investor group would acquire all of the
outstanding  common  stock  of  the  Company  for  $35.05  per  share  in  cash,
representing  a premium of  approximately  29% over the October 22, 1999 closing
price  of  $27.25,  the  last  trading  day  prior  to the  announcement  of the
transaction.  Berkshire  Hathaway  will invest  approximately  $1.25  billion in
common stock and convertible preferred stock and $800 million in nontransferable
trust preferred stock. Mr. Scott will contribute  approximately  $280 million in
cash and current securities of the Company and Mr. Sokol will contribute current
securities  of the Company  having a value of  approximately  $18 million.  Upon
completion of the transaction, Berkshire Hathaway will own not more than 9.9% of
the voting stock, Mr. Scott will own  approximately  88% of the voting stock and
Mr.  Sokol will own  approximately  2% of the voting  stock.  In  addition,  the
transaction is subject to the investor group obtaining evidence  satisfactory to
them that neither they nor their  affiliates  will be subject to regulation as a
registered holding company under the Public Utility Holding Company Act of 1935,
as amended.  Following  the merger,  it is expected  that the Company  will be a
public utility  holding company exempt from the provisions of the Public Utility
Holding Company Act of 1935, as amended, except for Section 9(a)(2) thereof.

The Company has or will file applications requesting the approval of the Federal
Energy  Regulatory  Commission,  the Nuclear  Regulatory  Commission  and,  with
respect to the transfer of jurisdictional gas properties,  the Illinois Commerce
Commission. In addition, the Company and members of the investor group will file
their notices under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended,  and the pre-merger  notification  period must expire. The Company will
also file an application  with the Iowa  Utilities  Board which has the right to
review the proposed  transaction and to disapprove it only if found not to be in
the public  interest.  State  regulators in Illinois,  Nebraska and South Dakota
will  also be  notified  and the  transaction  is  subject  to  approval  by the
shareholders of the Company at a special meeting.  The Company currently expects
that the transaction will be completed by the end of April 2000.

On  September  24,  1999,  the Company  commenced a cash offer for all  $121.115
million of its presently  outstanding  9.5% Senior Notes.  The Company  received
tenders from holders of an aggregate of $121.083  million  principal  which were
paid in October 1999, at a redemption price of 109.798% plus accrued interest.

8.   COMPREHENSIVE INCOME:

Comprehensive  income for the three months ended September 30, 1999 and 1998 was
$66.7  million and $57.5  million,  respectively,  and for the nine months ended
September 30, 1999 and 1998 was $106.5 million and $125.6 million, respectively.
Comprehensive  income differs from net income due primarily to foreign  currency
translation adjustments.

9.   ACCOUNTING PRONOUNCEMENT:

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments
and Hedging  Activities",  which established  accounting and reporting standards
for  derivative  instruments  and for hedging  activities.  It requires  that an
entity  recognize  all  derivatives  as  either  assets  or  liabilities  in the
statement of financial  position and measure  those  instruments  at fair value.
This  statement was amended by SFAS No. 137 which delayed  implementation.  This
statement is now  effective  for all fiscal  quarters of fiscal years  beginning
after June 15, 2000.  The Company is in the process of evaluating  the impact of
this accounting pronouncement.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS:
- ---------------------

The following is  management's  discussion  and analysis of certain  significant
factors  which have affected the  Company's  financial  condition and results of
operations  during  the  periods  included  in the  accompanying  statements  of
operations.

As a result of the  acquisition  of MHC and the sales of Coso and an interest in
CE Generation,  the Company's future results will differ  significantly from the
Company's historical results.

ACQUISITIONS/DISPOSITIONS:

On August 11, 1998,  the Company  entered  into an Agreement  and Plan of Merger
with MHC. The  MidAmerican  Merger closed on March 12, 1999 and the Company paid
$27.15 in cash for each  outstanding  share of MHC  common  stock for a total of
approximately  $2.42  billion  in a  merger,  pursuant  to which  MHC  became an
indirect  wholly  owned  subsidiary  of the Company.  Additionally,  the Company
reincorporated  in the State of Iowa, was renamed  MidAmerican  Energy  Holdings
Company and upon closing became an exempt public utility holding company.

The  consummation  of the MidAmerican  Merger was conditioned  upon receipt of a
number of regulatory and  shareholder  approvals and the  disposition of partial
interests in certain of the Company's  power  generating  facilities in order to
maintain the qualifying  facilities  status of such independent power generating
facilities.  On February  26,  1999,  the Company  closed the sale of all of its
ownership  interests in the Coso Project to Caithness Energy LLC  ("Caithness").
The price  includes  $205 million in cash and the  assumption  of  approximately
$67.7  million  in  debt.  On  February  8,  1999,  the  Company  created  a new
subsidiary, CE Generation LLC ("CE Generation") and subsequently transferred its
interest in the Imperial  Valley  Projects and Gas Plants to CE  Generation.  On
March 2, 1999, CE Generation closed the sale of $400 million aggregate principal
amount of its  7.416%  Senior  Secured  Bonds due 2018.  On March 3,  1999,  the
Company closed the sale of 50% of its ownership interests in CE Generation to an
affiliate  of El Paso  Energy  Corporation  for an  aggregate  consideration  of
approximately  $245  million in cash,  $6.5 million in  contingent  payments and
$23.5 million in equity  commitments.  Including the gross  proceeds from the CE
Generation debt offering,  the aggregate  consideration was  approximately  $675
million.

BUSINESS OF MHC:

MHC's  interests  include 100% of the common stock of MEC,  MidAmerican  Capital
Company,  MidAmerican  Services  Company  and  Midwest  Capital  Group.  MEC  is
primarily engaged in the business of generating, transmitting,  distributing and
selling electricity and in distributing,  selling and transporting  natural gas.
MidAmerican Capital Company manages marketable securities and passive investment
activities, security services and other energy-related, nonregulated activities.
MidAmerican  Services provides energy  management and related services.  Midwest
Capital  Group  functions as a regional  business  development  company in MEC's
service territory.

Currently,  MEC has gas and  electric  operations  in Iowa,  Illinois  and South
Dakota and gas operations in Nebraska.  Most of MEC's business is conducted in a
rate-regulated  environment  and  accordingly,  many of its  decisions as to the
source and use of resources and other  strategic  matters are  evaluated  from a
utility  business  perspective.  MEC's  operations are seasonal in nature with a
disproportionate  percentage of revenues and earnings  historically being earned
in the Company's first and third quarters.

                                      -15-


Through  October 6, 1999,  MHC owned  approximately  95% of the common  stock of
MidAmerican Realty Services. On October 6, 1999, MidAmerican Realty Services was
dividended  out of MHC  to  the  Company  and  merged  with  HomeServices.Com  a
subsidiary of the Company.  HomeServices.Com  includes the Company's real estate
brokerage operations and offers integrated real estate services in eleven states
including  residential  brokerage,  relocation,  title,  abstract  and  mortgage
services.

BUSINESS OF NORTHERN:

The operations of Northern Electric plc  ("Northern"),  an indirect wholly owned
subsidiary of the Company,  consist  primarily of the distribution and supply of
electricity,  supply of natural gas and other auxiliary businesses in the United
Kingdom.  Northern's  operations are seasonal in nature with a  disproportionate
percentage of revenues and earnings  historically  being earned in the Company's
first and fourth quarters.

Northern  receives  electricity from the national grid  transmission  system and
distributes  it to  customers'  premises  using  its  network  of  transformers,
switchgear  and  cables.  Substantially  all  of  the  customers  in  Northern's
authorized  area are connected to  Northern's  network and can only be delivered
electricity through Northern's distribution system,  regardless of whether it is
supplied by Northern's own supply business or by other suppliers, thus providing
Northern  with  distribution  volume that is stable from year to year.  Northern
charges  access  fees for the use of the  distribution  system.  The  prices for
distribution  are controlled by a prescribed  formula that limits increases (and
may require  decreases)  based upon the rate of inflation in the United  Kingdom
and other regulatory action.

On August 12, 1999, the United Kingdom's  Office of Gas and Electricity  Markets
("OFGEM") issued a draft report proposing a range of 18% to 23% of net regulated
revenue reductions for the distribution  business of Northern beginning April 1,
2000. The report proposed revenue  reductions for all public  electricity supply
companies in Great  Britain.  On October 8, 1999, the Company  received  further
proposals  from OFGEM that  clarified  its  intentions  regarding  the  proposed
distribution  price  reductions.  Proposed  distribution  price  reductions were
revised below the initial range of 18% - 23% to 17%.  Revised price controls are
expected in November 1999, and will become effective from April 1, 2000.

Northern's supply business  primarily involves the bulk purchase of electricity,
through a central  pool,  and  subsequent  resale to individual  customers.  The
supply  business  generally is a high volume  business which tends to operate at
lower profitability levels than the distribution business.  Prior to November 4,
1998,  Northern was the  exclusive  supplier of  electricity  to premises in its
authorized area,  except where the maximum demand of a customer was greater than
100kW.  Beginning  November  4, 1998,  liberalization  of the  entire  market in
Northern's  area  commenced in stages with complete  liberalization  achieved in
Northern's authorized area by the end of April 1999.

On  October  8,  1999,  OFGEM  indicated  an  initial   proposed   reduction  of
approximately 15% in Northern's supply rate cap for its electric supply business
(sales to  ultimate  customers).  The final  OFGEM  report on the  supply  price
adjustment is expected at the end of November  1999,  and will become  effective
April 1, 2000.

In the  market  between  100kW  and  1MW of  electricity  demand,  Northern  has
significantly  increased  its sales  during 1998 and 1999.  In the October  1999
contract round, sales increased by an additional 27% over the amount of business
that was available for renewal.  Northern is now one of the largest  electricity
suppliers in this sector of the U.K. market.

Northern also competes to supply gas inside and outside its authorized  area. In
the supply of gas to the business  market,  Northern expects to more than double
its annual  gas sales in 1999 from  1997.  In the  residential  market  Northern
currently supplies gas to approximately  560,000 customers.  Northern is now the
third largest gas supplier of the new entrants in the U.K. residential market.

POWER GENERATION PROJECTS:

On February 8, 1999,  the Company  created a new  subsidiary,  CE Generation LLC
("CE  Generation")  and  subsequently  transferred  its interest in the Imperial
Valley Projects and Gas Plants to CE Generation. On March 2, 1999, CE Generation
closed the sale of $400 million aggregate  principal amount of its 7.416% Senior
Secured Bonds due 2018. On March 3, 1999,  the Company closed the sale of 50% of
its  ownership  interests  in CE  Generation  to an  affiliate of El Paso Energy
Corporation  for an aggregate  consideration  of  approximately  $245 million in
cash,  $6.5  million  in  contingent   payments  and  $23.5  million  in  equity
commitments.  Including the gross proceeds from the CE Generation debt offering,
the aggregate  consideration was approximately $675 million.  Due to the sale of
50%  of its  interests  in CE  Generation,  the  Company  has  accounted  for CE
Generation as an equity investment  beginning March 3, 1999. Prior to that date,
CE Generation results were fully consolidated.

For purposes of consistent presentation, plant capacity factors for Vulcan, Hoch
(Del Ranch),  Elmore and Leathers  (collectively the "Partnership  Project") are
based on  capacity  amounts of 34, 38, 38, and 38 net MW  respectively,  and for
Salton  Sea I,  Salton  Sea  II,  Salton  Sea  III  and  Salton  Sea  IV  plants
(collectively the "Salton Sea Project") are based on capacity amounts of 10, 20,
49.8 and 39.6 net MW respectively  (the  Partnership  Project and the Salton Sea
Project are collectively  referred to as the "Imperial Valley  Project").  Plant
capacity factors for Saranac, Power Resources, NorCon and Yuma (collectively the
"Gas  Plants")  are based on capacity  amounts of 240,  200,  80, and 50 net MW,
respectively.  Capacity  amounts  for Upper  Mahiao,  Malitbog  and  Mahanagdong
(collectively,  the  "Philippine  Projects")  are  119,  216  and  165  net  MW,
respectively.  Each  plant  possesses  an  operating  margin  which  allows  for
production in excess of the amount listed above.  Utilization  of this operating
margin is based upon a variety of factors and can be  expected  to vary  between
calendar quarters, under normal operating conditions.

On  February  26,  1999,  the  Company  closed the sale of all of its  ownership
interests  in the Navy I, Navy II and BLM,  collectively  the Coso  Project,  to
Caithness.  The price  includes  $205  million  in cash plus the  assumption  of
approximately $67.7 million in debt.

RESULTS OF OPERATIONS FOR THE PERIODS ENDED SEPTEMBER 30, 1999 AND 1998:

Operating  revenue  increased in the third  quarter of 1999 to $1,062.6  million
from $600.9  million for the same period in 1998,  a 76.8%  increase.  Operating
revenue  increased  in the nine  months  ended  September  30,  1999 to $2,864.0
million from  $1,813.3  million for the same period in 1998,  a 57.9%  increase.
Northern's  operating  revenue  increased in the third quarter of 1999 to $424.2
million from $393.9  million for the same period in 1998 and for the nine months
ended September 30, 1999 to $1,449.2  million from $1,266.5 million for the same
period in 1998,  primarily  due to higher  volumes  of gas  supplied  as well as
higher electricity supply revenues. Operating revenue decreased due to the sales
of Coso and the 50% interest in CE Generation.  The acquisition of MHC accounted
for  $587.3  million  in  operating  revenue  in the third  quarter  of 1999 and
$1,198.5 million in the period from March 12, 1999 through September 30, 1999.

The increases in electricity  supplied for the three months ended  September 30,
1999 and the nine months ended  September 1999 from the same periods in 1998 are
due  primarily to the increase in supply  volumes for  customers  outside of the
franchise  area.  The increase in electricity  distributed  for the three months
ended  September 30, 1999 and decreases in electricity  distributed for the year
to date ended September 1999 from the same periods in 1998 are due to changes in
demand in the  franchise  area.  The  increase in gas supplied in 1999 from 1998
reflects the  increased  volume as the domestic gas supply  business in the U.K.
opened up to  competition  as a result of regulatory  changes and the successful
dual fuel marketing campaign.

The  capacity  factor for the nine months  ended  September  30, 1999  decreased
compared to the same period in 1998, due to scheduled  turbine  overhauls at Del
Ranch,  Leathers and Elmore. The decrease in kWh produced for both the three and
nine month  periods  ending  September  1999  compared to September  1998 is the
result of the sale of Coso.

The capacity factor of the Gas Plants reflects certain contractual curtailments.
The increases  from the prior period was primarily due to the severe winter snow
and ice storms which caused  transmission  curtailments at Saranac, as well as a
turbine overhaul at PRI in the first quarter of 1998.

Interest  and  other  income  increased  in the third  quarter  of 1999 to $27.4
million  from $26.9  million for the same period in 1998, a 1.9%  increase.  The
increase is primarily due to increased earnings in equity investments.  Interest
and other income  increased for the year to date period ended  September 1999 to
$100.9 million from $79.3 million in the same period in 1998.  Higher  corporate
cash  balances,  the  addition of MHC amounts  due to the  acquisition,  and the
addition of equity income from CE Generation accounted for the increase.

On May 18, 1999, the Company  announced the sale of  approximately  6.74 million
shares  of  McLeodUSA  ("McLeod")  Class A common  stock,  through  a  secondary
offering by McLeod,  at $55.625 per share.  Proceeds from the sale exceeded $375
million,  with a resulting  after-tax gain to the Company of approximately $47.1
million or $0.65 per diluted share.

Cost of sales  increased  in the third  quarter of 1999 to $515.4  million  from
$265.6  million for the same  period in 1998,  a 94.1%  increase.  Cost of sales
increased  in the nine months  ended  September  1999 to $1,462.5  million  from
$848.0 million from the same period in 1998, a 72.5% increase. The increases are
primarily due to higher volumes of gas and electricity  supplied at Northern and
the acquisition of MHC.

Operating  expense increased in the third quarter of 1999 to $263.3 million from
$109.1  million  for the same  period  in 1998,  a  141.3%  increase.  Operating
expenses  increased in the year to date ended  September  1999 to $695.9 million
from  $345.8  million  for the same  period  in 1998,  a  101.2%  increase.  The
increases are primarily due to the  acquisition  of MHC partially  offset by the
sales of Coso and an interest in CE Generation.

Depreciation and  amortization  increased in the third quarter of 1999 to $115.6
million  from  $81.4  million  for the same  period  in 1998.  Depreciation  and
amortization increased in the year to date September 1999 to $306.4 million from
$247.0 million in the same period in 1998, a 24.0%  increase.  The increases are
due to the acquisition of MHC, partially offset by the sales of Coso and the 50%
interest in CE Generation.

Interest expense,  less amounts  capitalized,  increased in the third quarter of
1999 to $106.2  million from $81.3  million for the same period in 1998, a 30.6%
increase.  Interest expense, less amounts capitalized,  increased in the year to
date September 1999 to $321.8 million from $241.0 million, a 33.5% increase. The
increases are primarily due to the  acquisition  of MHC and the greater  average
outstanding debt balances.

The provision  for income taxes  decreased in the third quarter of 1999 to $27.5
million from $32.1  million for the same period in 1998, a 14.3%  decrease.  The
provision for income taxes increased in the year to date ended September 1999 to
$90.8 million from $72.6 million for the same period in 1998, a 25.1%  increase.
The year to date increase is due to higher  pretax income during the  comparable
period of 1999.
                                     -19-


Minority  interest  increased in the third  quarter to $12.2  million from $10.5
million  for the  same  period  in 1998,  a 16.2%  increase.  Minority  interest
increased in the nine months ended  September  1999 to $35.5  million from $30.8
million in the same period in 1998, a 15.3% increase.  The increase is primarily
due to the  acquisition  of MHC  which  has  minority  interests  in the form of
preferred stock outstanding.

Income  before  extraordinary  items  increased in the third  quarter of 1999 to
$49.7 million or $0.82 per share,  from $47.6 million or $0.80 per share for the
same period in 1998. Income before  extraordinary items increased in the year to
date ended  September  1999 to $150.5  million  or $2.51 per share  from  $107.4
million or $1.78 per share for the same period in 1998.

Due to the early  retirements of the Senior Discount Notes, the Limited Recourse
Notes and the 9.5% Senior Notes,  the Company recorded  extraordinary  losses of
approximately $3.2 million and $40.1 million,  net of tax, in the three and nine
months ended September 30, 1999, respectively.

LIQUIDITY AND CAPITAL RESOURCES:
- -------------------------------

The  Company  has  available  a variety  of  sources of  liquidity  and  capital
resources,  both internal and external.  These resources  provide funds required
for current  operations,  construction  expenditures,  debt retirement and other
capital requirements.

The Company's  cash and cash  equivalents  were $167.3  million at September 30,
1999 as compared to $1,606.1  million at December 31, 1998. The majority of this
decrease  was due to the cash used to acquire  MHC.  In  addition,  the  Company
recorded separately restricted cash and investments of $384.5 million and $637.6
million  at  September  30,  1999  and  December  31,  1998,  respectively.  The
restricted  cash  balance as of  September  30, 1999 is  comprised  primarily of
amounts  deposited in  restricted  accounts from which the Company will fund the
various  projects under  construction.  Additionally,  the accounts  include the
Dieng  Project  and  the  Patuha  Project  restricted  cash  accounts;  and  the
Philippine Projects' cash reserves for the debt service reserve funds.

Financing Activity

The remaining  outstanding Senior Discount Notes of $369.5 million were redeemed
on January 15, 1999 at a redemption price of 105.125% plus accrued interest.

On  January  29,  1999,  the  Company  commenced  a cash  offer  for  all of its
outstanding Limited Recourse Notes. The Company received tenders from holders of
an aggregate of  approximately  $195.8  million of principal  which were paid on
March 3, 1999, at a redemption price of 110.025% plus accrued interest.

On March 11, 1999,  MidAmerican Funding,  LLC, a wholly-owned  subsidiary of the
Company,  issued  $200  million of 5.85%  Senior  Secured  Notes due 2001,  $175
million of 6.339%  Senior  Secured  Notes due 2009,  and $325  million of 6.927%
Senior  Secured  Bonds due 2029.  The proceeds  from the  offering  were used to
complete the MidAmerican Merger.

On May 18, 1999, CalEnergy Capital Trust, a subsidiary of the Company,  effected
the conversion of $103.8 million of 6 1/4% Convertible Preferred Securities into
approximately 3.5 million shares of common stock of the Company.  The Securities
were  converted  at a rate of 1.6728  shares of common  stock of the Company for
each Security,  equivalent to a conversion  price of $29.89 per share of Company
common stock.

The Company  redeemed $39.5 million in principal  value of the 9.5% Senior Notes
at an aggregate price of $43.5 million throughout the third quarter of 1999. The
Company has redeemed  $103.9 million in principal  value through the nine months
ended  September 30, 1999.  Due to the early  extinguishment  of this debt,  the
Company recorded an extraordinary  loss of $3.2 million in the third quarter and
$8.5 million in the nine months ended September 30, 1999.

                                      -20-


On  September  24,  1999,  the Company  commenced a cash offer for all  $121.115
million of its presently  outstanding  9.5% Senior Notes.  The Company  received
tenders from holders of an aggregate of $121.083 million principal which were
paid in October 1999, at a redemption price of 109.798% plus accrued interest.

As of September 30, 1999, the Company held 23.1 million shares of treasury stock
at a cost of $752.3 million.  On May 25, 1999, the Company announced that it had
increased to 3.75  million the number of shares of its common  stock  authorized
for  repurchase  on the open  market.  The Company has  repurchased  3.4 million
shares of common  stock in 1999 at an  aggregate  cost of  $104.8  million.  The
treasury  shares will provide shares for issuance  under the Company's  employee
stock  option  and  share  purchase  plan  and  other  outstanding   convertible
securities.  The stock  repurchase  plan  minimizes  the dilutive  effect of the
additional shares issued under these plans.

Acquisitions and Dispositions

On August 11, 1998,  the Company  entered  into an Agreement  and Plan of Merger
with MHC. The  MidAmerican  Merger closed on March 12, 1999 and the Company paid
$27.15 in cash for each  outstanding  share of MHC  common  stock for a total of
approximately  $2.42  billion  in a  merger,  pursuant  to which  MHC  became an
indirect  wholly  owned  subsidiary  of the Company.  Additionally,  the Company
reincorporated  in the State of Iowa, was renamed  MidAmerican  Energy  Holdings
Company and upon closing became an exempt public utility holding company.

The  consummation  of the MidAmerican  Merger was conditioned  upon receipt of a
number of regulatory and  shareholder  approvals and the  disposition of partial
interests in certain of the Company's  power  generating  facilities in order to
maintain the qualifying  facilities  status of such independent power generating
facilities.

On  February  26,  1999,  the  Company  closed  the sale of all of its  indirect
ownership  interest in the Coso Project to  Caithness.  The price  includes $205
million in cash and the assumption of approximately $67.7 million in debt.

On February 8, 1999,  the Company  created a new  subsidiary,  CE Generation and
subsequently  transferred  its interest in the Imperial  Valley Projects and Gas
Plants to CE Generation. On March 2, 1999, CE Generation closed the sale of $400
million aggregate  principal amount of its 7.416% Senior Secured Bonds due 2018.
On March 3, 1999, the Company closed the sale of 50% of its ownership  interests
in CE Generation to an affiliate of El Paso Energy  Corporation for an aggregate
consideration of approximately  $245 million in cash, $6.5 million in contingent
payments and $23.5 million in equity  commitments.  Including the gross proceeds
from  the  CE  Generation  debt  offering,   the  aggregate   consideration  was
approximately $675 million.

On May 18, 1999, the Company  announced the sale of  approximately  6.74 million
shares  of  McLeodUSA  ("McLeod")  Class A common  stock,  through  a  secondary
offering by McLeod,  at $55.625 per share.  Proceeds from the sale exceeded $375
million,  with a resulting  after-tax gain to the Company of approximately $47.1
million or $0.65 per diluted share.

In  July  1999,  the  Company's  wholly-owned  subsidiary,  CE Gas,  closed  its
acquisition  of a 67% interest in the Anglia  Field  located in the Southern Gas
Basin in the North Sea. The  producing  field is expected to provide the Company
with 89 billion cubic feet of natural gas reserves,  which will give the Company
further options in support of its growing gas supply business in the U.K.

On October 14, 1999, the Company announced that  HomeServices.Com,  a subsidiary
of the Company, closed its initial public offering of 3,250,000 shares of common
stock at $15 per share.  HomeServices sold 2,187,500 shares and the Company, the
selling stockholder, sold 1,062,500 shares in the offering.  HomeServices.Com is
the  surviving  entity of a merger with  MidAmerican  Realty  Services.  The net
proceeds  received  by it in the  offering  will be used for  general  corporate
purposes,   which  are  expected  to  include  acquisitions  and  the  continued
development of its E-commerce operations.

                                      -21-


On October 24, 1999,  the Company and entities  representing  an investor  group
comprised of Berkshire Hathaway Inc. ("Berkshire Hathaway"),  Walter Scott, Jr.,
the current  chairman  of Level 3  Communications,  Inc.  and a director of the
Company,  and David L.  Sokol,  Chairman  and  Chief  Executive  Officer  of the
Company, executed a definitive agreement and plan of merger whereby the investor
group  would  acquire  all of the  outstanding  common  stock of the Company for
$35.05 per share in cash,  representing a premium of approximately  29% over the
October  22, 1999  closing  price of $27.25,  the last  trading day prior to the
announcement of the transaction.  Berkshire  Hathaway will invest  approximately
$1.25 billion in common stock and  convertible  preferred stock and $800 million
in   nontransferable   trust   preferred   stock.   Mr.  Scott  will  contribute
approximately $280 million in cash and current securities of the Company and Mr.
Sokol  will  contribute  current  securities  of the  Company  having a value of
approximately  $18  million.  Upon  completion  of  the  transaction,  Berkshire
Hathaway  will own not more than 9.9% of the voting  stock,  Mr.  Scott will own
approximately 88% of the voting stock and Mr. Sokol will own approximately 2% of
the voting stock. In addition,  the transaction is subject to the investor group
obtaining  evidence  satisfactory to them that neither they nor their affiliates
will be subject to regulation as a registered  holding  company under the Public
Utility  Holding  Company Act of 1935, as amended.  Following the merger,  it is
expected that the Company will be a public utility  holding  company exempt from
the  provisions of the Public Utility  Holding  Company Act of 1935, as amended,
except for Section 9(a)(2) thereof.

The Company has or will file applications requesting the approval of the Federal
Energy  Regulatory  Commission,  the Nuclear  Regulatory  Commission  and,  with
respect to the transfer of jurisdictional gas properties,  the Illinois Commerce
Commission. In addition, the Company and members of the investor group will file
their notices under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended,  and the pre-merger  notification  period must expire. The Company will
also file an application  with the Iowa  Utilities  Board which has the right to
review the proposed  transaction and to disapprove it only if found not to be in
the public  interest.  State  regulators in Illinois,  Nebraska and South Dakota
will  also be  notified  and the  transaction  is  subject  to  approval  by the
shareholders of the Company at a special meeting.  The Company currently expects
that the transaction will be completed by the end of April 2000.

The  Company  developed  and owns the rights to  proprietary  processes  for the
extraction  of minerals from  elements in solution in the  geothermal  brine and
fluids  utilized  at its  Imperial  Valley  plants (the  "Salton Sea  Extraction
Project")  as well  as the  production  of  power  to be used in the  extraction
process. A pilot plant has successfully  produced commercial quality zinc at the
Company's Imperial Valley Project.  The Company intends to sequentially  develop
facilities for the extraction of manganese,  silver,  gold, lead, boron, lithium
and other products as it further develops the extraction technology. The Company
is also investigating  producing silica as an extraction project. Silica is used
as a filler for such products as paint, plastics and high temperature cement.

CalEnergy  Minerals LLC, an indirect wholly owned subsidiary of the Company,  is
constructing  the  Zinc  Recovery  Project  which  will  recover  zinc  from the
geothermal  brine (the "Zinc Recovery  Project").  Facilities  will be installed
near the Imperial Valley Project sites to extract a zinc chloride  solution from
the  geothermal  brine  through an ion exchange  process.  This solution will be
transported  to a central  processing  plant  where zinc ingots will be produced
through  solvent  extraction,  electrowinning  and casting  processes.  The Zinc
Recovery Project is designed to have a capacity of  approximately  30,000 metric
tons per year and is scheduled to commence commercial operation in mid-2000.  In
September 1999,  CalEnergy  Minerals LLC entered into a sales agreement  whereby
all zinc produced by the Zinc Recovery Project will be sold to Cominco, LTD. The
initial term of the agreement expires in December 2005.

The  Zinc  Recovery   Project  is  being   constructed  by  Kvaerner  U.S.  Inc.
("Kvaerner")  pursuant  to a date  certain,  fixed-price,  turnkey  engineering,
procurement  and   construction   contract  (the  "Zinc  Recovery   Project  EPC
Contract").  Kvaerner is a wholly owned indirect  subsidiary of Kvaerner ASA, an
international  engineering  and  construction  firm  experienced  in the metals,
mining and  processing  industries.  Total  project  costs of the Zinc

                                      -22-


Recovery  Project are expected to be approximately  $200.9 million.  The Company
has incurred $60.5 million of such costs through September 30, 1999.

Imperial Valley Construction Projects

Salton Sea Power LLC, an indirect wholly owned  subsidiary of CE Generation,  is
constructing  Salton Sea V.  Salton Sea V will be a 49 net MW  geothermal  power
plant,  which will sell  approximately  one-third  of its net output to the Zinc
Recovery  Project.  The  remainder  will be sold  through the  California  Power
Exchange ("PX").

Salton  Sea V will be  constructed  pursuant  to a date  certain,  fixed  price,
turnkey  engineering,  procurement and construction  contract (the "Salton Sea V
EPC Contract") by Stone & Webster Engineering  Corporation ("SWEC"). SWEC is one
of the world's leading  engineering and construction  firms for the construction
of electric power plants and, in particular, geothermal power plants. Salton Sea
V is scheduled to commence commercial operation in mid-2000. Total project costs
of Salton Sea V are  expected to be  approximately  $119.1  million.  Salton Sea
Power  LLC has  incurred  approximately  $61.3  million  of such  costs  through
September 30, 1999.

CE  Turbo  LLC,  an  indirect  wholly  owned  subsidiary  of  CE  Generation  is
constructing the CE Turbo Project.  The CE Turbo Project will have a capacity of
10 net MW.  The net  output  of the CE  Turbo  Project  will be sold to the Zinc
Recovery Project or sold through the PX.

The  Partnership   Projects  are  upgrading  the  geothermal   brine  processing
facilities  at the  Vulcan  and Del  Ranch  Projects  with  the  Region  2 brine
facilities  construction.  In  addition  to  incorporating  the pH  modification
process,  which has reduced operating costs at the Salton Sea Projects, the more
efficient  facilities  are  expected  to achieve  additional  economies  through
improved brine processing  systems and the utilization of more modern equipment.
The Partnership  Projects expect these  improvements will reduce  brine-handling
operating costs at the Vulcan Project and the Del Ranch Project.

The CE Turbo Project and the Region 2 brine  facilities  construction  are being
constructed  by  SWEC  pursuant  to  a  date  certain,   fixed  price,   turnkey
engineering,  procurement and  construction  contract (the "Region 2 Upgrade EPC
Contract").  The  obligations  of  SWEC  are  guaranteed  by  Stone  &  Webster,
Incorporated.  The CE Turbo Project is scheduled to commence initial  operations
in mid-2000 and the Region 2 brine  facilities  construction  is scheduled to be
completed in  early-2000.  Total project costs for both the CE Turbo Project and
the Region 2 brine  facilities  construction  are  expected to be  approximately
$63.7  million.  The Company has incurred  $29.3  million of such costs  through
September 30, 1999.

Casecnan

CE Casecnan  Water and Energy  Company,  Inc.,  a  Philippine  corporation  ("CE
Casecnan")  which at  completion  of the  Casecnan  Project is expected to be at
least 70% indirectly owned by the Company, is constructing the Casecnan Project,
a combined irrigation and 150 net MW hydroelectric power generation project (the
"Casecnan  Project")  located in the central  part of the island of Luzon in the
Republic of the Philippines.

CE Casecnan has entered into a fixed-price,  date certain,  turnkey engineering,
procurement  and  construction  contract to  complete  the  construction  of the
Casecnan  Project (the  "Casecnan  Construction  Contract").  The work under the
Casecnan  Construction Contract is being conducted by a consortium consisting of
Cooperativa  Muratori  Cementisti CMC di Ravenna and Impresa Pizzarotti & C. Spa
working  together  with  Siemens  A.G.,  Sulzer  Hydro Ltd.,  Black & Veatch and
Colenco  Power  Engineering  Ltd.  The Casecnan  Project,  which was expected to
become  operational in the fourth quarter of 2000, may now become operational in
the first  quarter  of 2001 due to  certain  recent  delays  experienced  by the
contractor.
                                      -23-


Indonesia

On December 2, 1994,  subsidiaries of the Company,  Himpurna  California  Energy
Ltd. ("HCE") and Patuha Power,  Ltd. ("PPL",  together with HCE, the "Indonesian
Subsidiaries")  executed separate joint operation  contracts for the development
of geothermal steam fields and geothermal  power  facilities  located in Central
Java in  Indonesia  with  Perusahaan  Pertambangan  Minyak  Dan Gas Bumi  Negara
("Pertamina"),  the  Indonesian  national  oil company,  and  executed  separate
"take-or-pay"  energy sales contracts  ("ESCs") with both Pertamina and P.T. PLN
(Persero) ("PLN"),  the Indonesian national electric utility.  The Government of
Indonesia provided sovereign  performance  undertakings of the obligations under
the joint operating and "take-or-pay" contracts.

In 1997 and 1998 a series of  Indonesian  government  decrees and other  actions
(including  the  non-payment  of all monthly  invoices  from HCE's Dieng Unit I,
which became  operational in March 1998) created  significant  uncertainty as to
whether  PLN  and  the  Indonesian  government  would  honor  their  contractual
obligations to the Indonesian Subsidiaries.

On or about August 14, 1998, the Company,  through the Indonesian  Subsidiaries,
began arbitration proceedings against PLN in connection with the HCE's and PPL's
geothermal  power  projects  in  Indonesia,  the Dieng  Project  and the  Patuha
Project.  The arbitration  was conducted under the United Nations  Commission of
International  Trade Law  ("UNCITRAL")  rules.  In its  Statement of Claim,  HCE
alleged that PLN breached the "take-or-pay"  provisions of its ESA with HCE and,
through its conduct has  repudiated the ESC with HCE. In its Statement of Claim,
PPL  alleged  that,  in  conjunction  with PLN's  breach of the ESC with HCE and
through its conduct,  PLN  repudiated the ESC with PPL. On or about December 10,
1998,  PLN delivered  two  Statements of Defense in respect of the HCE claim and
the PPL claim.

An arbitral  tribunal found that PLN had  materially  breached the provisions of
the Energy  Sales  Contracts  between PLN and both HCE and PPL,  and awarded HCE
$391,711,652  and  PPL  $180,570,322,  and  ordered  PLN  to pay  these  amounts
immediately.  Following PLN's failure to pay such amounts,  PPL and HCE demanded
payment  pursuant  to  the  sovereign  performance  undertakings  issued  by the
Minister of Finance  ("MOF") on behalf of the Republic of Indonesia  ("ROI") and
following the ROI's failure to pay brought an arbitration against the ROI for
breach of those undertakings.

A final  award  was  issued  by an  international  arbitration  panel in the ROI
arbitration on October 15, 1999 which found that:

     o The ROI is in breach of its performance undertakings and violated
       international law.

     o The ROI is required to pay HCE and PPL an aggregate amount of
       approximately $575 million.

The Company  carries  political  risk insurance on its investment in HCE and PPL
through  OPIC,  an agency of the U.S.  Government,  as well as  through  private
market insurers. Such insurance covers expropriation of the Company's investment
in HCE and PPL, as well as  material  breaches by PLN of the ESCs and by the ROI
of its  performance  undertakings.  The  Company  filed  claims in the amount of
approximately  $290 million  pursuant to such political risk insurance  policies
with OPIC and the private market insurers and intends to vigorously  pursue such
claims with OPIC and the private market insurers, if necessary.

Cordova

Cordova Energy Company LLC  ("Cordova"),  an indirect wholly owned subsidiary of
the Company, has commenced construction of a 537 MW gas-fired power plant in the
Quad Cities,  Illinois  area (the "Cordova  Project").  Cordova has entered into
engineering,  procurement  and  construction  contract  with  SWEC to build  the
project.  Total project costs are estimated to be approximately  $288.9 million.
The Company has also entered into a power sales agreement with a unit of El Paso
Energy  Corporation ("El Paso").  Under the power sales agreement,  El Paso will
purchase all the capacity and energy from the project  until  December 31, 2019.
However,  Cordova has the option to

                                     -24-


elect on an annual basis to retain up to 50% of the project  output for sales to
others.  The  construction of the Cordova Project is expected to be completed in
mid-2001.

On September 10, 1999 Cordova Funding Corporation ("Cordova Funding"),  a wholly
owned  subsidiary of the Company,  closed the $225 million  aggregate  principal
amount  financing for the  construction of the Cordova  Project.  As part of the
financing,  approximately $93.5 million of 8.64% Series A-1 Senior Secured Bonds
due 2019 were issued. Additional Series A Senior Secured Bonds will be issued as
required to fund construction. Cordova Funding will loan the proceeds to Cordova
as  required.  The  Company has  incurred  $39.0  million of such costs  through
September 30, 1999. Total equity funding is expected to be  approximately  $63.9
million.

Evolution of the Domestic Utility Industry

The U.S. utility industry  continues to evolve into an increasingly  competitive
environment.  In  virtually  every  region  of  the  country,   legislative  and
regulatory actions are being taken which result in customers having more choices
in their energy decisions.

In the electric industry,  the traditional  vertical  integration of generation,
delivery and marketing is being  unbundled,  with the  generation  and marketing
functions being deregulated.  For local gas distribution businesses, the supply,
local delivery and marketing  functions are similarly being separated and opened
to competitors for all classes of customers.  While retail electric  competition
is presently not permitted in Iowa,  MEC's primary market,  legislation to do so
was  introduced  in Iowa's  legislature  during  the 1999  session.  While  this
legislation  has not passed,  it is expected to be considered  again by the Iowa
legislature in 2000.  Deregulation of the gas supply  function  related to small
volume  customers is also being  considered by the Iowa Utilities Board ("IUB").
MEC is actively participating in the legislative and regulatory processes.

The  generation  and retail  portions of MEC's  electric  business  will be most
affected by competition. The introduction of competition in the wholesale market
has resulted in a proliferation of power marketers and a substantial increase in
market activity.  As retail choice evolves,  competition from other  traditional
utilities,  power marketers and customer-owned  generation could put pressure on
utility margins.

During  the  transition  to  full  competition,   increased  volatility  in  the
marketplace  can be  expected.  With the  elimination  of the energy  adjustment
clause in Iowa, MEC is exposed to movements in energy  prices.  Although MEC has
sufficient low cost generation under typical operating conditions for its retail
electric  needs,  a loss of adequate  generation by MEC at a time of high market
prices could subject MEC to losses on its energy sales.

Legislative and Regulatory Evolution

In December 1997, the Governor of Illinois signed into law a bill to restructure
Illinois'  electric utility industry and transition it to a competitive  market.
Under the law,  beginning October 1, 1999, larger  non-residential  customers in
Illinois and 33% of the remaining non-residential Illinois customers are allowed
to select their provider of electric supply services.  All other non-residential
customers  will have supplier  choice  starting  December 31, 2000.  Residential
customers all receive the  opportunity to select their electric  supplier on May
1, 2002.

In addition,  the law provides for Illinois  earnings  above a certain  level of
return on common equity ("ROE") to be shared equally  between  customers and MEC
beginning  in April  2000.  MidAmerican's  ROE level  will be based on a rolling
two-year average, with the first determination being based on an average of 1998
and 1999.  The ROE level at which MEC will be  required  to share  earnings is a
multi-step  calculation  of average  30-year  Treasury Bond rates plus 5.50% for
1998 and 1999.  Legislation passed in July 1999 increases the benchmark for 2000
through 2004 to 8.50% above the 30-year  Treasury  bond rate.  If the  resulting
average Treasury Bond rate were equal to the December 1998 30-year Treasury Bond
rate, the ROE level above which sharing must occur would be approximately  10.6%
for 1998 and 1999 and 13.6% for 2000 - 2004.  The law allows MEC to mitigate

                                     -25-


the  sharing of  earnings  above the  threshold  ROE  through  accelerated  cost
recognition  that would reduce  MEC's  earnings.  MEC  continues to evaluate its
strategy regarding the sharing mechanism.

Accounting Effects of Industry Restructuring

A possible  consequence of  competition in the utility  industry is that SFAS 71
may no longer apply.  SFAS 71 sets forth  accounting  principles  for operations
that are  regulated  and meet certain  criteria.  For  operations  that meet the
criteria,  SFAS 71 allows,  among other things, the deferral of costs that would
otherwise  be  expensed  when  incurred.  A majority of MEC's  electric  and gas
utility  operations  currently  meet the  criteria  required by SFAS 71, but its
applicability is periodically reexamined.  If portions of its utility operations
no longer  meet the  criteria of SFAS 71, MEC could be required to write off the
related  regulatory  assets and liabilities  from its balance sheet, and thus, a
material adjustment to earnings in that period could result. As of September 30,
1999, MEC had $266 million of regulatory assets on its balance sheet.

Domestic Rate Matters: Electric

Electric revenue from MEC's Iowa industrial customers were reduced by $6 million
annually and electric prices for MEC's Iowa commercial customers were reduced by
$4 million  annually through several steps from mid-1997 to the end of 1998. The
reductions  were  achieved  through a retail  access pilot  project,  negotiated
individual  electric  contracts and a $1.5 million  tariffed rate  reduction for
certain  non-contract  commercial  customers.  The negotiated electric contracts
have differing  terms and conditions as well as prices.  The contracts  range in
length  from five to ten  years,  and some have  price  renegotiation  and early
termination  provisions  exercisable  by either party.  The vast majority of the
contracts are for terms of seven years or less,  although,  some large customers
have agreed to 10-year contracts.  Prices are set as fixed prices; however, many
contracts allow for potential price  adjustments  with respect to  environmental
costs,  government imposed public purpose programs,  tax changes, and transition
costs. While the contract prices are fixed (except for the potential  adjustment
elements),  the costs MEC incurs to fulfill  these  contracts  will vary.  On an
aggregate  basis,  the annual  revenues  under contract are  approximately  $180
million.

If MEC's annual Iowa  electric  jurisdictional  ROE exceeds 12%,  then  earnings
above the 12% level will be shared equally between customers and MEC; if the ROE
exceeds 14%,  then  two-thirds  of MEC's share of these  earnings  above the 12%
level will be used for accelerated recovery of certain regulatory assets. A 1997
pricing plan settlement  agreement precludes MEC from filing for increased rates
prior to 2001 unless the ROE falls below 9%. Other parties signing the agreement
are prohibited from filing for reduced rates prior to 2001 unless the ROE, after
reflecting  credits  to  customers,  exceeds  14%.  On April 14,  1999,  the IUB
approved, subject to additional refund, MEC's ROE calculation. During the second
quarter of 1999,  MEC refunded $2.2 million to its Iowa  non-contract  customers
related to the 1998 ROE calculation.  The agreement also eliminated MEC's energy
adjustment clause,  and, as a result, the cost of fuel is not directly passed on
to customers.

Environmental Matters

Following  recommendations provided by the Ozone Transport Assessment Group, the
EPA, in November 1997,  issued a Notice of Proposed  Rulemaking which identified
22 states and the District of Columbia as making a significant  contribution  to
nonattainment  of the ozone  standard in downwind  states in the eastern half of
the United States.  The  nonattainment of the "downwind  states" is based on the
ozone standard  established  prior to the 1997  revisions  discussed  below.  In
September 1998, the EPA issued its final rules in this  proceeding.  Iowa is not
subject to the  emissions  reduction  requirements  in the final rules,  and, as
such,  MEC's  facilities  are not  currently  subject  to  additional  emissions
reductions as a result of this initiative.

On July 18, 1997, the EPA adopted  revisions to the National Ambient Air Quality
Standards  (NAAQS) for ozone and a new  standard  for fine  particulate  matter.
Based on data to be obtained from monitors  located  throughout each state,  the
EPA will  determine  which  states  have areas that do not meet the air  quality
standards  (i.e.,  areas

                                    -26-


that are  classified  as  nonattainment).  If a state has area(s)  classified as
nonattainment  area(s),  the state is required to submit a State  Implementation
Plan specifying how it will reach  attainment of the standards  through emission
reductions or other means.

In May 1999,  the U.S.  District  Court of Appeals for the  District of Columbia
Circuit  remanded the standards  adopted in July 1997 back to the EPA indicating
the EPA had not expressed sufficient justification for the basis of establishing
the    standards    and    ruling    that    the    EPA   has    exceeded    its
constitutionally-delegated  authority  in  setting  the  standards.  The EPA has
appealed  the  court's  ruling to the full panel of the U.S.  District  Court of
Appeals for the District of Columbia Circuit.  Argument in the appeal proceeding
is scheduled for the fall of 1999.  As a result of the court's  decision and the
current status of the standards,  the impact of any new standards on MidAmerican
is currently unknown.

Nuclear Decommissioning

Each licensee of a nuclear facility is required to provide  financial  assurance
for the cost of  decommissioning  its  licensed  nuclear  facility.  In general,
decommissioning  of a nuclear  facility means to safely remove the facility from
service and restore the property to a condition allowing unrestricted use by the
operator.  Based on information  presently available,  MEC expects to contribute
approximately  $42 million  during the period 1999  through  2003 to an external
trust  established  for the  investment  of funds for  decommissioning  the Quad
Cities  Station.  Approximately  65% of the  trust's  funds are now  invested in
domestic corporate debt and common equity securities.  The remainder is invested
in investment grade municipal and U.S. Treasury bonds.

MEC makes  payments  to  Nebraska  Public  Power  District  ("NPPD")  related to
decommissioning  Cooper.  These payments are reflected in operating  expenses in
the income  statement.  NPPD  estimates  call for MEC to pay  approximately  $57
million to NPPD for Cooper  decommissioning during the period 1999 through 2003.
NPPD  invests  the funds  predominately  in U.S.  Treasury  Bonds and other U.S.
Government  securities.  Approximately  20% was  invested in domestic  corporate
debt. MEC's obligation for Cooper  decommissioning may be affected by the actual
plant shutdown date and the status of the power purchase  contract at that time.
In July  1997,  NPPD  filed a lawsuit in United  States  District  Court for the
District of Nebraska  naming MEC as the defendant  and seeking a declaration  of
MEC's rights and obligations in connection  with Cooper nuclear  decommissioning
funding. See Note 6 to the financial statements regarding Cooper litigation.

Cooper and Quad Cities Station  decommissioning  costs charged to Iowa customers
are included in base rates,  and recovery of increases in those  amounts must be
sought through the normal ratemaking process. MEC currently recovers Quad Cities
Station decommissioning costs charged to Illinois customers through a rate rider
on customer billings.

Securitization of Accounts Receivable

In 1997, MEC entered into a revolving agreement,  which expires in 2002, to sell
all of its right,  title and  interest in the  majority  of its billed  accounts
receivable to MidAmerican Energy Funding Corporation  (Funding Corp.), a special
purpose entity  established to purchase  accounts  receivable from MEC.  Funding
Corp. in turn sold receivable  interests to outside investors.  In consideration
for the sale, MEC received $70 million in cash and the remaining  balance in the
form of a subordinated  note from Funding Corp. The agreement is structured as a
true sale, as  determined by SFAS No. 125,  under which the creditors of Funding
Corp. will be entitled to be satisfied out of the assets of Funding Corp.  prior
to any value being  returned to MEC or its  creditors.  Therefore,  the accounts
receivable  sold are not  reflected on the balance  sheet.  As of September  30,
1999, $98.4 million of accounts receivable, net of reserves, were sold under the
agreement.

In  December  1998,  Northern  entered  into  a  revolving  receivable  purchase
agreement with Kitty Hawk Funding  Corporation  ("Kitty Hawk"),  an unaffiliated
special  purpose  entity  established  to  purchase  accounts  receivable.   The
agreement,  which expires in December 1999,  allows  Northern to sell all of its
rights,  title and interest in the

                                     -27-



majority of its billed electricity accounts receivable and to borrow against its
unbilled electricity accounts receivable.  In March 1999, Northern received $161
million  in cash  associated  with the  agreement,  $143  million  of which  was
accounted for as a sale and $18 million of which was accounted for as a loan.

Development Activity

The  Company is  actively  seeking to  develop,  construct,  own and operate new
energy projects, both domestically and internationally, the completion of any of
which is subject to  substantial  risk.  Development  can require the Company to
expend significant sums for preliminary  engineering,  permitting,  fuel supply,
resource  exploration,  legal and other expenses in preparation  for competitive
bids  which the  Company  may not win or before it can be  determined  whether a
project is  feasible,  economically  attractive  or  capable of being  financed.
Successful  development and construction is contingent upon, among other things,
negotiation on terms  satisfactory to the Company of engineering,  construction,
fuel supply and power sales contracts with other project  participants,  receipt
of required  governmental  permits and  consents  and timely  implementation  of
construction.  There  can  be no  assurance  that  development  efforts  on  any
particular  project,  or the Company's  development  efforts generally,  will be
successful.

The Company  believes  that the  international  independent  power  market holds
opportunities  for  financially  attractive  energy  product  development.   The
financing,  construction  and development of projects  outside the United States
entail significant political and financial risks (including, without limitation,
uncertainties  associated with first time privatization efforts in the countries
involved,   currency   exchange   rate   fluctuations,   currency   repatriation
restrictions,  political instability,  civil unrest and expropriation) and other
structuring  issues  that  have the  potential  to cause  substantial  delays or
material  impairment  of the value of the  project  being  developed,  which the
Company may not be fully capable of insuring  against.  The  uncertainty  of the
legal  environment in certain foreign countries in which the Company may develop
or acquire  projects could make it more difficult for the Company to enforce its
rights under  agreements  relating to such projects.  In addition,  the laws and
regulations of certain  countries may limit the ability of the Company to hold a
majority  interest in some of the projects  that it may develop or acquire.  The
Company's  international  projects  may, in certain  cases,  be  terminated by a
government. Projects in operation, construction and development are subject to a
number of uncertainties  more specifically  described in the Company's Form 8-K,
dated March 26, 1999, filed with the Securities and Exchange Commission.

Year 2000

What is generally  known as the year 2000 ("Y2K")  computer  issue arose because
many  existing  computer  programs  and  embedded  systems use only the last two
digits to refer to a year.  Therefore,  those computer  programs do not properly
distinguish  between  a year  that  begins  with "20"  instead  of "19".  If not
corrected,  many computer  applications  could fail or create erroneous results.
The failure to correct a material Y2K item could result in an  interruption  in,
or a failure of, certain normal business activities or operations  including the
generation,  distribution,  and supply of  electricity  and  natural  gas.  Such
failures  could  materially  and  adversely  affect  the  Company's  results  of
operations, liquidity and financial condition.

The Y2K issue creates uncertainty for the Company from potential issues with its
own  computer  systems and from third  parties  with whom the  Company  deals on
transactions  worldwide.  The Company's operations utilize systems and equipment
provided  by other  organizations.  As a result,  Y2K  readiness  of  suppliers,
vendors,  service providers or customers could impact the Company's  operations.
The Company is  assessing  the  readiness of such  constituent  entities and the
impacts on those entities that rely upon the Company's services.  The Company is
unable to  determine at this time  whether the  consequences  of Y2K failures of
third  parties  will  have  a  material  impact  on  the  Company's  results  of
operations, liquidity or financial condition.

The  Company  has  commenced,  for all of its  information  systems,  a Y2K date
conversion   project  to  address  all  necessary  code  changes,   testing  and
implementation  in order  to  resolve  the Y2K  issue.  The  Company  created  a

                                     -28-


worldwide  Y2K  project  team  to  identify,  assess  and  correct  all  of  its
information  technology (IT) and non-IT systems, as well as, identify and assess
third party systems.

The Company has identified and assessed  substantially  all of its IT and non-IT
systems and is currently in the process of repairing or replacing  those systems
which it believes are not Y2K  compliant.  As of September 30, 1999, the Company
is  approximately  99% complete in repairing or replacing  those systems  deemed
critical.  The Company expects to be 100% complete of correcting,  testing,  and
compliance before year-end.

Total Y2K expenditures,  for both repairing or replacing  non-compliant  systems
and contingency  planning,  are expected to total  approximately  $23.4 million.
Through September 30, 1999, the Company has paid approximately  $15.6 million of
Y2K  expenditures.  The Company has renovated or replaced several  non-compliant
systems to gain enhanced functionalities. The cost of these types of renovations
and replacements is not reported herein since their development and installation
were not driven by Y2K  concerns.  The  Company  is not aware of any  additional
material costs  necessary to bring all of its systems into  compliance  however,
there is no assurance that additional costs will not be incurred.

Contingency plans identifying credible worst-case scenarios are being developed.
The  contingency  plans are comprised of both  mitigation and recovery  aspects.
Mitigation entails planning to reduce the impact of unresolved Y2K problems, and
recovery  entails  planning to restore  services in the event that Y2K  problems
occur.  Although  plans  are  substantially   complete,  they  will  be  refined
throughout the remainder of the year,  based on results of contingency  planning
drills and changes in circumstances.

MEC  participated  in  contingency  planning  drills  coordinated  by the  North
American Electric  Reliability Council on April 9, 1999 and September 8-9, 1999.
During those drills MEC did not experience any unexpected results.

Although management believes that the Y2K project will be substantially complete
before January 1, 2000, any  unforeseen  failures of the Company's  and/or third
parties'  computer systems could have a material impact on the Company's ability
to conduct its business.
