                                 THE COMPANY 

OVERVIEW 

   CalEnergy Company, Inc. is a fast-growing global energy company with an 
increasingly diversified portfolio of regulated and non-regulated assets. The 
focus of the Company has evolved over time from development and acquisition 
activities in the domestic and international power generation market to 
strategic electric and gas utility acquisitions, with a particular emphasis 
on investment-grade countries such as the U.S., U.K., Australia, Canada, New 
Zealand and the countries of Western Europe. This focus has provided the 
Company with increased scale, skill and revenue diversity and enhanced credit 
quality of cash flows and additional growth opportunities associated with 
each of the acquired businesses. The MidAmerican Merger is being implemented 
in furtherance of this strategy. The Company's investments in related 
activities (e.g., producing gas fields and gas reserves and advanced utility 
information systems) are primarily intended to support and augment the 
profitability of its existing core businesses. 

   CalEnergy was founded in 1971 and, through its subsidiaries, manages and 
currently owns interests in over 5,000 megawatts ("MW") of power generation 
facilities in operation, construction and development worldwide, including 20 
generating facilities which it currently operates. (This will increase to 
approximately 9,000 MW and 30 operating facilities following the MidAmerican 
Merger.) Since both the demand for electric power and the pace of electric 
industry privatization continues to increase on a global basis, the power 
generation segment will remain a significant investment and growth 
opportunity for the Company in addition to its core utility operations. The 
Company's utility operations are currently conducted through its subsidiary, 
Northern Electric plc ("Northern"), which engages in the supply and 
distribution of electricity and gas to approximately 2 million customers in 
the U.K., as well as other related utility business activities. 

   During the past five years, the Company has achieved significant growth in 
earnings and assets while diversifying the underlying revenue base and 
improving the associated credit quality of that base through: (i) strategic 
acquisitions that broaden the geographic and business scope of the Company's 
overall 

                               S-1           
<PAGE>
 activities and that expand the Company's core competencies; (ii) enhancement 
of the financial and technical performance of existing and acquired business 
operations; and (iii) development, construction and acquisition of 
incremental energy-related assets to support and expand the scope of existing 
operations within focused geographic regions. 

   The Company's management team has a proven track record of project 
development, operation, acquisition integration and portfolio 
diversification. Since 1991, the Company's operating and financial results 
have improved significantly through the employment of a disciplined 
acquisition, development and management philosophy. In 1991, the Company's 
EBITDA was derived largely from non-regulated, domestic power generation 
activities. After giving effect to the Securities Offering, the MidAmerican 
Merger, the Equity Offering and the Non-Recourse Financing, the Company's 
adjusted pro forma EBITDA for the year ended December 31, 1997 is $1,307 
million and the Company's total assets as of June 30, 1998 are approximately 
$12.9 billion. 

   The Company's goal is to continue to foster long-term sustained growth 
built upon a solid foundation of diversified and high quality assets and 
skill sets. As part of this strategy, the Company recently agreed to acquire 
(the "MidAmerican Merger") MidAmerican Energy Holdings Company ("MidAmerican" 
or "MEC"), which provides the Company with an attractive integrated U.S. 
utility growth platform. Following the MidAmerican Merger, the Company 
expects that approximately 80% of the Company's cash flows will be derived 
from highly stable, investment-grade credit quality sources, of which 
approximately 60% will be contributed from regulated U.S. and U.K. utility 
operations. There can be no assurance that the MidAmerican Merger, the Equity 
Offering or the Non-Recourse Financing will be consummated. 

   A condensed financial structure overview reflecting the current ratings of 
the principal senior debt securities issued by CalEnergy and its subsidiaries 
(including MidAmerican as though the MidAmerican Merger had been consummated) 
is presented below.(1)

 NORTHERN 

   In February 1997, the Company acquired Northern, one of the twelve U.K. 
regional electric companies (each, a "REC") which came into existence as a 
result of the restructuring and subsequent privatization of the electricity 
industry that occurred in the U.K. in 1990. Northern's principal business is 
the distribution of electricity in its authorized area located in northeast 
England which covers approximately 14,400 square kilometers and has a 
population of approximately 3.2 million people. As a regional platform, 
Northern's related activities also include: (i) the supply of electricity and 
gas inside and outside its authorized area, and (ii) ownership interests in 
producing gas fields in the North Sea and gas, transmission and storage 
operations. Consistent with the Company's goals, these related activities 
serve to support the operations and growth of the Northern electric and gas 
supply business. In addition, based on the skills and experience developed in 
the U.K. deregulated energy market, the Company has developed proprietary and 
advanced information systems ("Aurora/IT") which are currently being utilized 
in the supply business in the U.K., and are expected to be directly 
applicable to the Company's other utility operations, such as MidAmerican's 
utility operations. 

   The Northern acquisition was financed with $586 million contributed by the 
Company, and approximately $700 million of non-recourse debt at a new holding 
company for Northern ("CE Electric UK Funding Company") to be serviced solely 
from Northern's cash flow. Following the acquisition, Northern's ratings were 
affirmed by Moody's and reduced from A-to BBB+ by S&P. The ratings for CE 
Electric UK Funding Company are Baa1 and BBB+ from Moody's and S&P, 
respectively. 

   Since the Northern acquisition, the Company has focused the goals and 
objectives for Northern's key business units (Distribution, Utility Services, 
Supply and Aurora/IT) as follows: 

   o  Maintain the strength and stability of the core electric distribution 
      business; 

   o  Grow the electricity and gas supply business prudently and profitably; 

   o  Be a low-cost provider while maintaining reliable, high-quality 
      service; and 

   o  Increase the profitability of and grow Northern's other regulated 
      businesses in a disciplined manner and within the financial means of 
      the Northern organization. 

   The results to date have exceeded the Company's original expectations. 
Accomplishments for and attributes of the respective U.K. business units 
include: 

Distribution and Utility Services 

   o  Improved reliability and customer service, as measured by the Office 
for Electricity Regulation; and 

   o  Lower staff levels and reduced overtime. 

Supply 

   o  1.5 million electricity customers; 

   o  Added 600,000 new gas customers in past year; 

   o  Dual fuel offering (a first time innovation for the U.K. market); 

   o  A tripling of business gas sales; and 

   o  An increase in over 100kW electricity sales by 30%, 45% and 50% in the 
      last three contract rounds (now the third largest U.K. supplier in this 
      sector). 

Aurora/IT 

   o  System handles an average of 3,800 new gas and electricity customer 
applications per day, with peak volume of 10,000 new applications per day; 

   o  Facilitates supply and billing to new gas and electricity customers; 
and 

   o  Increase in customer satisfaction through flexible pricing and payment 
options.

 OVERVIEW OF PENDING MIDAMERICAN MERGER 

   On August 11, 1998, the Company entered into an Agreement and Plan of 
Merger pursuant to which it has agreed to acquire, subject to the conditions 
set forth therein, MidAmerican for approximately $2.6 billion in cash, in a 
transaction in which approximately $1.6 billion in debt and preferred stock 
of MidAmerican will remain outstanding (the "MidAmerican Merger"). Pursuant 
to the MidAmerican Merger, CalEnergy will reincorporate in Iowa and will be 
renamed MidAmerican Energy Holdings Company. The Securities will remain 
senior debt of CalEnergy, and MidAmerican's existing debt and preferred stock 
will remain debt and preferred stock of such utility subsidiary following the 
MidAmerican Merger. 

   MidAmerican is the largest combined electric and gas utility in Iowa with 
648,000 electric and 619,000 gas customers. It has gas and electric 
operations in Iowa, Illinois and South Dakota and gas operations in Nebraska. 
The regulated service area is comprised of 10,600 square miles with a total 
population of 1.7 million. MidAmerican has an installed generation capacity 
of approximately 4,000 MW, comprised of 71% coal, 19% natural gas and 10% 
nuclear fuel sources. Due to its geographic location and fuel sources, 
MidAmerican is a low cost producer of electricity in the Mid-Continent Area 
Power Pool. Mid-American supplies from time to time electricity to other 
major energy markets in the midwestern U.S. such as the Chicago area, St. 
Louis, Kansas City, Milwaukee and Minneapolis. MidAmerican's gas operations 
are served by at least four major gas pipelines. 

   The Company believes that the electric power industry within the U.S. will 
continue its current pace of deregulation, with regulated distribution 
operations expected to follow the established U.K. regulatory model (with 
incentive-based rates or price caps). As a result, the Company believes that 
the MidAmerican Merger will provide the opportunity to apply the knowledge, 
skills and systems gained at Northern and, with the addition of a strong and 
complementary management team, to establish a platform from which a domestic 
energy distribution and supply business can be profitably managed and 
expanded over time. 

   The consummation of the MidAmerican Merger is conditioned upon receipt of 
approvals of the shareholders of the Company and MidAmerican, as well as the 
Nuclear Regulatory Commission, the Federal Energy Regulatory Commission, the 
Iowa Utilities Board and the expiration or termination of the applicable 
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 
1976, as amended. In addition, the partial disposition of interests in 
certain of the Company's power generating facilities will be required prior 
to the consummation of the MidAmerican Merger in order to maintain the 
qualifying facilities status of such independent power generating facilities. 
There can be no assurance as to the timing of the required regulatory 
approvals, the ability to obtain regulatory and shareholder approvals, that 
such approvals will contain satisfactory terms and conditions or that the 
MidAmerican Merger will be consummated. See "Risk Factors--Acquisition 
Uncertainties" in the accompanying Prospectus. 

   Closing of the MidAmerican Merger is expected to occur by the end of the 
first quarter of 1999. 

BENEFITS OF PENDING MIDAMERICAN MERGER 

   The Company believes the following economic and strategic benefits will be 
realized from the MidAmerican Merger: 

   o  Continues CalEnergy's transformation to an integrated global energy 
      company with the increased scale and skill base required to efficiently 
      compete as energy markets continue to deregulate throughout the world; 

   o  Combines existing CalEnergy competitive supply expertise with 
      MidAmerican's approximately 4,000 MW of efficient low cost, primarily 
      coal-fired generating capacity having access to high-priced markets 
      (e.g., Chicago); 

   o  Provides a platform for continued U.S. growth through the addition of a 
      strong and complementary management team able to identify midwest 
      regional development and expansion opportunities in both assets and 
      supply, as well as to apply the Aurora/IT technology to MEC's 
      operations; 

                               S-4

    o  Enhances CalEnergy's financial position through cash flow and earnings 
       accretion beginning with the first full year of operations following 
       the consummation of the transaction; and 

   o  Improves CalEnergy's consolidated credit profile through increased 
      diversification of cash flow and earnings sources derived principally 
      from the investment-grade regulated utility operations. 

FINANCING PLAN 

   The Company proposes to fund the MidAmerican Merger utilizing a financing 
plan substantially similar in nature to that previously employed for the 
Northern acquisition, as illustrated below.

   CalEnergy proposes to establish a wholly-owned, special-purpose entity 
("MidAmerican FinCo") which will issue approximately $750 million of debt 
financing (the "Non-Recourse Financing") that will partially fund the 
MidAmerican Merger, and that will be non-recourse to CalEnergy and solely 
serviced with operating cash flow from MEC. The remaining acquisition 
financing of approximately $1,430 million will be raised through common 
and/or preferred securities and/or other equity-linked securities of 
CalEnergy (the "Equity Offering") and varying levels of senior debt of 
CalEnergy and MidAmerican FinCo. Certain of the proceeds of the Equity 
Offering may be replaced by proceeds from non-core asset sales by the 
Company. The timing and composition of such financing elements are flexible 
and subject to optimization and refinement as financing market conditions 
change. There can be no assurance that the Non-Recourse Financing or the 
Equity Offering will be consummated.

 STRATEGY 

   The Company's diversification and growth strategy remains focused upon 
strategic utility acquisitions and other investment opportunities created by 
the continuing deregulation and privatization in energy sectors throughout 
the world, particularly within investment-grade countries such as the U.S., 
U.K., Australia, Canada, New Zealand and the countries of Western Europe. 

   In each market, the Company's strategy is principally comprised of the 
following key elements: 

   o  DIVERSIFICATION AND GROWTH THROUGH INTERNATIONAL AND DOMESTIC 
      ACQUISITIONS. The Company has successfully completed five acquisitions 
      in the past four years, each of which was accretive to earnings and 
      cash flow, and reflective of the Company's disciplined investment 
      philosophy. The Company believes that several of these acquisitions 
      have provided it with specialized skills and an expertise base which 
      enhances its competitive position in those areas that it has targeted 
      for future growth. For example, the Company's acquisition of Northern 
      was the first step in its planned expansion into the distribution and 
      supply (electricity and gas) business segments in the U.S. which will 
      be achieved, in part, through the MidAmerican Merger. As a direct 
      result of the competitive experience afforded by progressive U.K. 
      energy deregulation, the Company believes that it possesses the 
      demonstrated knowledge and skill base required to effectively compete 
      in open supply markets as such markets develop in the U.S. An 
      additional benefit of the Northern acquisition was the opportunity to 
      develop Aurora/IT, a proprietary array of sophisticated billing and 
      information systems, which the Company believes to be a critically 
      important component of effective operations in a deregulated utility 
      environment. The Company further believes that there will be immediate 
      opportunities to apply Aurora/IT at MEC and elsewhere in the U.S. as 
      such markets progressively deregulate. 

   o  DIVERSIFICATION AND GROWTH THROUGH GREENFIELD DEVELOPMENT OF ENERGY 
      PROJECTS. The Company continues to view the domestic and international 
      power generation, transmission and distribution markets, particularly 
      when integrated with upstream natural gas operations, as an attractive 
      market for the selected development of new greenfield energy 
      opportunities, an area in which it has substantial expertise. 

      In addition, the price volatility recently experienced in tight summer 
      U.S. markets has highlighted the need for additional capacity in certain 
      regions such as the Midwest. Based on forecasts for those Midwest 
      markets as well as the regional market knowledge and experience at MEC, 
      the Company has announced plans to jointly develop with MEC a 
      non-regulated gas-fired plant with a generating capacity of up to 
      approximately 500 MW. The Company plans to continue a focused 
      development effort on power and integrated gas projects with a 
      particular emphasis on investment-grade countries such as the U.S., 
      U.K., Australia, Canada, New Zealand and the countries of Western 
      Europe. 

   o  CONTINUED ENHANCEMENT OF CREDIT QUALITY AND DIVERSIFICATION OF REVENUE 
      BASE, EARNINGS AND CASH FLOWS. The Company currently has a diversified 
      revenue base including its long-term contract-based power generation 
      activities and its regulated utility operations. The MidAmerican Merger 
      will provide for further complementary and beneficial diversification 
      of both the Company's business profile (through an increased weighting 
      on regulated utility operations) and revenue base (through an increase 
      of investment-grade revenues generated from stable, regulated sources). 
      Following the MidAmerican Merger, the Company expects that 
      approximately 80% of the Company's cash flows will be derived from 
      highly stable, investment-grade credit quality sources, of which 
      approximately 60% will be contributed from regulated U.S. and U.K. 
      utility operations. 

   o  MAINTENANCE OF PRUDENT FINANCIAL AND RISK MANAGEMENT PRACTICES. The 
      Company has and will continue to consistently maintain what it believes 
      to be prudent financial and risk management practices. A primary 
      component of the Company's financing philosophy is the demonstrated 

                               S-6           
<PAGE>
       employment of investment-grade, non-recourse financing at subsidiary 
      levels. Such a financing strategy provides for fundamental protection 
      of the Company's other assets since the non-recourse structures 
      utilized by the Company require that (with certain minimal exceptions) 
      the funds borrowed for the purposes of financing such investments are 
      serviced solely from the cash flow generated by, and the assets of, 
      that discrete investment. As discussed previously, the MidAmerican 
      Merger financing plan calls for a MidAmerican FinCo financing structure 
      that is similar to the structure successfully employed at Northern. 

      This financing philosophy then permits the Company to act, in part, as a 
      holding company which utilizes portfolio management investment 
      practices. The Company is able to efficiently raise capital from a 
      variety of sources to contribute as equity into the non-recourse 
      investment vehicles, typically in amounts sufficient to achieve 
      investment-grade levels at those vehicles. The Company's continued 
      adherence to its strict investment criteria has resulted in a continued 
      upward trend in the Company's credit profile as evidenced by the 
      historical improvement in its credit ratings. 

      In addition, the Company plans to optimize its capital structure by 
      refinancing debt when market conditions permit. Approximately $543 
      million of the net proceeds of the Securities Offering will be used, in 
      part, to prefund the Company's retirement of the outstanding 
      $529,640,000 10 1/4% Senior Discount Notes due 2004 (the "Senior 
      Discount Notes"), which become callable on January 15, 1999. 

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

   o  CONTINUED PROFIT ENHANCEMENT THROUGH OPERATING EFFICIENCIES WHILE 
      MAINTAINING QUALITY AND RELIABILITY OF SERVICE. 

   The principal executive offices of the Company are located at 302 South 
36th Street, Suite 400, Omaha, Nebraska 68131 and its telephone number is 
(402) 341-4500. The Company was incorporated in 1971 under the laws of the 
State of Delaware.

                                 senior unsecured obligations of CalEnergy. 
                                 The Securities will rank senior to all 
                                 existing and future subordinated 
                                 indebtedness of CalEnergy. The Securities

                                 existing and, to the extent permitted under 
                                 the Indenture, future secured indebtedness 
                                 of CalEnergy and to all indebtedness and 
                                 other liabilities of CalEnergy's 
                                 subsidiaries, projects and joint ventures to 
                                 the extent of the assets of such entities. 
                                 As of June 30, 1998, on a pro forma basis, 
                                 after giving effect to the MidAmerican 
                                 Merger, the Equity Offering, the 
                                 Non-Recourse Financing and the Securities 
                                 Offering and the use of the net proceeds 
                                 therefrom, CalEnergy would have had $200 
                                 million of secured limited recourse parent 
                                 company indebtedness (of which $0 is 
                                 currently recourse to CalEnergy) and 
                                 approximately $5,033 million of indebtedness 
                                 that represented the Company's proportionate 
                                 share of project and joint venture and 
                                 subsidiary debt, all of which would be 
                                 effectively senior to the Securities, and 
                                 approximately $575 million of indebtedness 
                                 that would be pari passu with the 
                                 Securities. See "Capitalization." 

Certain Covenants .............  The indenture governing the Securities (the 
                                 "Indenture") contains certain covenants 
                                 which, among other things, will restrict the 
                                 ability of CalEnergy, its Restricted

(1)    Reflects the acquisition of the remaining 50% of the Partnership 
       Projects (as defined herein) on April 17, 1996, the acquisition of 
       Falcon Seaboard on August 7, 1996 and the acquisition of majority 
       ownership of Northern by CE Electric U.K. plc ("CE Electric") on 
       December 24, 1996. In March 1997, the Company completed the acquisition 
       of Northern. 
(2)    The Company's operations have historically been seasonal in nature; 
       therefore, operating results and ratios for interim periods are not 
       indicative of the results for the full year. 
(3)    Reflects the KDG Acquisition (as defined herein) on January 2, 1998. 
(4)    Reflects a 1997 non-recurring charge of $87 million, or $1.29 per 
       share, and extraordinary item of $135,850, or $2.02 per share. 
(5)    The weighted average number of basic common shares outstanding was 47.2 
       million, 54.7 million, 67.3 million, 63.5 million and 60.7 million, 
       respectively, for the years ended December 31, 1995, 1996 and 1997 and 
       the six months ended June 30, 1997 and 1998. The number of diluted 
       shares outstanding was 56.2 million, 65.1 million, 68.7 million, 71.4 
       million and 74.6 million, respectively, for the years ended December 
       31, 1995, 1996 and 1997 and the six months ended June 30, 1997 and 
       1998. 
(6)    EBITDA means earnings before interest, taxes, depreciation, 
       amortization, and 1997 non-recurring item. 
(7)    Information concerning EBITDA is presented here not as a measure of 
       operating results, but rather as a measure of the Company's ability to 
       service debt. EBITDA should not be construed as an alternative to 
       either (i) operating income (determined in accordance with GAAP) or 
       (ii) cash flow from operating activities (determined in accordance with 
       GAAP). 
(8)    For purposes of computing historical ratios of earnings to fixed 
       charges, earnings are divided by fixed charges. "Earnings" represent 
       the aggregate of (a) the pre-tax income of the Company and (b) fixed 
       charges, less capitalized interest. "Fixed charges" represent interest 
       (whether expensed or capitalized), amortization of deferred financing 
       and bank fees, and the portion of rentals considered to be 
       representative of the interest factor (one-third of lease payments) and 
       preferred stock dividend requirements of majority-owned subsidiaries.

(1)    The Company's operations have historically been seasonal in nature; 
       therefore, operating results and ratios for interim periods are not 
       indicative of the results for the full year. 
(2)    EBITDA means earnings before interest, taxes, depreciation, 
       amortization, and 1997 non-recurring item. 
(3)    Information concerning EBITDA is presented here not as a measure of 
       operating results, but rather as a measure of the Company's ability to 
       service debt. EBITDA should not be construed as an alternative to 
       either (i) operating income (determined in accordance with GAAP) or 
       (ii) cash flow from operating activities (determined in accordance with 
       GAAP). 
(4)    For purposes of computing historical ratios of earnings to fixed 
       charges, earnings are divided by fixed charges. "Earnings" represent 
       the aggregate of (a) the pre-tax income of the Company, and (b) fixed 
       charges, less capitalized interest. "Fixed charges" represent interest 
       (whether expensed or capitalized), amortization of deferred financing 
       and bank fees, and the portion of rentals considered to be 
       representative of the interest factor (one-third of lease payments) and 
       preferred stock dividend requirements of majority-owned subsidiaries.

                               USE OF PROCEEDS 

   The net proceeds to the Company of the Securities Offering are estimated 
to be approximately $1,373 million. The Company expects to use approximately 
$830 million of the net proceeds from the Securities Offering, together with 
approximately $600 million of the net proceeds from the Equity Offering and 
approximately $740 million of net proceeds from the Non-Recourse Financing 
and available cash on hand, to complete the MidAmerican Merger. The closing 
of the Securities Offering will occur in advance of, and is not conditioned 
upon, the closing of the MidAmerican Merger. If for any reason the 
MidAmerican Merger was not consummated, the net proceeds of the Securities 
Offering would be used to make equity investments in future domestic or 
international energy projects, to fund possible future stock or asset 
acquisitions, for the possible repayment of debt and for other general 
corporate purposes. 

   The Company expects to use approximately $543 million of the net proceeds 
of the Securities Offering to refinance the Senior Discount Notes, which 
become callable on January 15, 1999.

   The following table sets forth (i) the consolidated capitalization of the 
Company at June 30, 1998, (ii) the pro forma consolidated capitalization of 
the Company as if the Securities Offering and the expected retirement of the 
Senior Discount Notes had occurred on June 30, 1998, and (iii) the pro forma 
consolidated capitalization of the Company as adjusted for the transactions 
described in clause (ii) and the consummation of the MidAmerican Merger, the 
Equity Offering and the Non-Recourse Financing as described in the notes to 
the Unaudited Pro Forma Combined Condensed Financial Data included elsewhere 
in this Prospectus Supplement. The table should be read in conjunction with 
the Company's historical consolidated financial statements and the notes 
thereto, and the pro forma financial statements and the notes thereto,

- ------------ 
(1)    The Company's operations have historically been seasonal in nature; 
       therefore, operating results and ratios for interim periods are not 
       indicative of the results for the full fiscal year. 
(2)    Reflects the acquisition of Magma Power Company which was completed on 
       February 24, 1995. 
(3)    Reflects the acquisition of the remaining 50% of the Partnership 
       Projects on April 17, 1996, the acquisition of Falcon Seaboard on 
       August 7, 1996 and the acquisition of majority ownership of Northern by 
       CE Electric on December 24, 1996. In March, 1997, the Company completed 
       the acquisition of Northern. 
(4)    Reflects the KDG Acquisition (as defined herein) on January 2, 1998. 
(5)    Reflects a 1997 non-recurring charge of $87 million, or $1.29 per 
       share, and an extraordinary item of $135,850, or $2.02 per share. 
(6)    The Company's 12% senior notes due 1995 were defeased in the first 
       quarter of 1994 in connection with the issuance of the Senior Discount 
       Notes, resulting in an extraordinary loss in 1994 in the amount of $2.0 
       million. 
(7)    On January 1, 1993, the Company adopted Statement of Financial 
       Accounting Standard No. 109, Accounting for Income Taxes, resulting in 
       a cumulative effect adjustment increasing net income by $4.1 million in 
       1993. 
(8)    EBITDA means earnings before interest, taxes, depreciation, 
       amortization, and non-recurring item (1997 asset valuation impairment). 
(9)    Information concerning EBITDA is presented here not as a measure of 
       operating results, but rather as a measure of the Company's ability to 
       service debt. EBITDA should not be construed as an alternative to 
       either (i) operating income (determined in accordance with U.S. GAAP) 
       or (ii) cash flow from operating activities (determined in accordance 
       with U.S. GAAP). 
(10)   For purposes of computing historical ratios of earnings to fixed 
       charges, earnings are divided by fixed charges. "Earnings" represent 
       the aggregate of (a) the pre-tax income of the Company and (b) fixed 
       charges, less capitalized interest. "Fixed charges" represent interest 
       (whether expensed or capitalized), amortization of deferred financing 
       and bank fees, and the portion of rentals considered to be 
       representative of the interest factor (one-third of lease payments) and 
       preferred stock dividend requirements of majority-owned subsidiaries.

                         THE BUSINESS OF THE COMPANY 

GENERAL 

   The Company is a growing global energy company which, after consummation 
of the MidAmerican Merger, will consist of the following operations: an 
electric and gas utility services company in the U.S., an electric and gas 
distribution and supply utility in the U.K., with over 3.2 million customers 
and over $12 billion in assets, and a proven developer of profitable 
independent power generation facilities around the world, with a particular 
focus on investment grade countries such as the U.S., U.K., Australia, 
Canada, New Zealand and the countries of Western Europe. The Company also 
owns and develops natural gas reserves in markets where such reserves can be 
utilized as an integral part of the Company's energy services business in 
that market (e.g., the U.K.). The overall goal of the Company is to be a 
leading provider of low cost energy services throughout the world as 
governments privatize or deregulate electricity and gas markets. 

   The Company's strategy, which is more fully described in the "Strategy" 
section at pages S-6 through S-7 herein, is comprised of the following key 
elements: 

   o  Diversification and growth through acquisition of international and 
      domestic utility and energy-related assets. 

   o  Diversification and growth through greenfield development of energy 
      generation, transmission and distribution projects. 

   o  Continued enhancement of the credit quality and diversification of its 
      revenue base, earnings and cash flows. 

   o  Adherence to prudent financial and risk management practices and strict 
      investment criteria. 

   o  Continued profit enhancement through operating efficiencies while 
      maintaining quality and reliability of service. 

Utility Operations 

 Northern Electric 

   Northern is a regional electric company headquartered in Newcastle, 
England providing electric and gas supply throughout England, Scotland and 
Wales and electric distribution services in Northeast England. Supply and 
distribution services are provided to over 2 million customers throughout 
England and Wales. 

   Northern operates in two primary businesses: (1) the distribution of 
electricity and (2) the supply of electricity and gas. The distribution 
business is a natural monopoly and as such is regulated by the Office for 
Electricity Regulation (the "Regulator"). The primary means of regulation is 
a tariff structure utilizing a price cap mechanism which sets the maximum 
price to be charged and allows Northern to retain a portion of all profits 
achieved through such tariffs. The price cap is reviewed periodically by the 
Regulator. 

   The United Kingdom has progressively deregulated its electric and gas 
industry and a competitive market now exists in both. Northern has to date 
been successful in profitably growing its customer base in the supply of 
electricity and gas. Over the past two years, the number of customers 
serviced by Northern has grown from approximately 1.4 million to 2.0 million. 
The country has over 25 million electric customers and over 21 million gas 
customers. 

   For more information on Northern, see pages S-21 through S-24 herein. 

 MidAmerican Energy Company 

   The Company has entered into a merger agreement with MidAmerican Energy 
Holdings Company, Inc., which is headquartered in Des Moines, Iowa and is the 
parent of MidAmerican Energy Company. The transaction represents the 
continuation of the Company's U.S. growth and diversification strategy to 
acquire a high-quality U.S. utility and compete for customers for the supply 
of electricity and/or gas utilizing MidAmerican's low cost generation assets 
and distribution system as an operational platform. 

                              S-20           
<PAGE>
    MidAmerican is the largest combined electric and gas utility in Iowa with 
648,000 electric and 619,000 gas customers. It has gas and electric 
operations in Iowa, Illinois and South Dakota and gas operations in Nebraska. 
The regulated service area is comprised of 10,600 square miles with a total 
population of 1.7 million. MidAmerican has an installed generation capacity 
of approximately 4,000 MW, comprised of 71% coal, 19% natural gas and 10% 
nuclear fuel sources. Due to its geographic location and fuel sources, 
MidAmerican is a low cost producer of electricity in the Mid-Continent Area 
Power Pool. Mid-American's transmission system interconnections also allow it 
to supply electricity to other major energy markets in the midwestern U.S. 
such as the Chicago area, St. Louis, Kansas City, Milwaukee and Minneapolis. 
MidAmerican's gas operations are served by at least four major gas pipelines. 

   Following the MidAmerican Merger, the Company will own interests in 
approximately 6,000 net MW of facilities in operation or construction having 
the following fuel sources: 47% coal, 19% geothermal, 26% natural gas, 6% 
nuclear and 2% hydroelectric. 

   For more information on MidAmerican, see pages S-24 through S-27 herein. 

Non-regulated Generation Operations: Power Project Portfolio 

   The Company has significant ownership interests in non-regulated 
generation facilities both domestically and internationally. Currently, the 
Company has net ownership interests of an aggregate of (i) 1,741 MW in 21 
projects in operation representing an aggregate net capacity of 3,565 MW of 
electric generating capacity, (ii) 275 MW in four projects under construction 
representing an aggregate net capacity of 360 MW of electric generating 
capacity, and (iii) 354 MW in projects in development representing an 
aggregrate capacity of 629 MW of electric generating capacity. 

   For more information on the Company's power generation project portfolio, 
see pages S-27 through S-28 herein. 

Gas Operations 

   The Company has been active in acquiring and developing interests in 
natural gas fields which have existing production and known reserves. The 
acquisition of gas assets and operations supports the Company's growth 
strategy in several ways: (1) gas operations are capable of providing stable, 
long-term supply to generation facilities; (2) owned production will play an 
integral role in the execution of supplying energy to the customer in 
competitive markets; and (3) gas development efforts are a low cost method of 
gaining entry, market intelligence and cash flow in new generation markets 
around the world. 

   The Company has interests in producing gas fields in the North Sea, and in 
the past year, the Company has acquired additional interests in gas fields 
and a gas pipeline in the North Sea. These interests include a 25% interest 
in the Esmond Transportation System which connects to the strategically 
important European gas hub at Bacton, England. In addition, the Company 
acquired the right to earn interests in the Yolla gas field offshore between 
Victoria and Tasmania in Australia and the Gin Gin field onshore near Perth 
in Western Australia. 

   For more information on the Company's producing gas field operations and 
fields in development, see page S-28 herein.

   Northern Electric Distribution Limited. Northern Electric Distribution 
Limited ("Northern Distribution"), a subsidiary of Northern, receives 
electricity from the national grid transmission system and distributes 
electricity to each customer's premises using Northern's 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 supplied with electricity through the Northern distribution system, 
regardless of whether the electricity is supplied by Northern's supply 
business or by other suppliers, thus providing Northern with distribution 
volume that is stable from year to year. Northern Distribution serves 
approximately 1.5 million customers in Northern's area and charges its 
customers access fees for the use of the distribution system. 

   At March 31, 1998, Northern's electricity distribution network (excluding 
service connections to consumers) included approximately 17,000 kilometers of 
overhead lines and approximately 26,000 kilometers of underground cables. 
Substantially all substations are owned in freehold, and most of the balance 
are held on leases which will not expire within 10 years. In addition to the 
circuits referred to above, Northern's distribution facilities also include 
approximately 24,000 transformers and approximately 24,000 substations. 

   Northern Electric and Gas Supply. Northern Electric and Gas Supply 
("Northern Supply") focuses on Northern's supply business and is responsible 
for marketing, tariff setting, contracts and customer service in connection 
with the supply of both electricity and gas. Northern's electricity supply 
business involves the bulk purchase of electricity, primarily from the Pool 
(as defined below), and subsequent sale to individual customers. Northern's 
supply business is subject to price control and is being progressively opened 
to competition. This price control limits the prices that Northern can charge 
to domestic and small non-domestic customers within its authorized area. 
Supplies to other customers are not regulated since the Director General of 
Electricity Supply ("the Regulator") has determined that the market is 
sufficiently competitive not to require this. 

   Under its public electricity supply ("PES") or "first tier" licence 
Northern has the right to supply electricity to all customers within its 
authorised area. Under its various "second tier" licenses Northern has the 
right to supply electricity in all other parts of Great Britain, subject to 
certain conditions relating to the opening of competition in the case of 
customers with demands below 100kW ("Franchise Supply Customers"). Northern 
also holds an equivalent licence permitting it to supply electricity in 
Northern Ireland. In Great Britain the market for electricity customers with 
a maximum demand above 1 megawatt ("MW") has been open to competition since 
privatisation and the market for customers with a maximum demand above 100kW 
became competitive in April 1994. Northern is one of the largest suppliers in 
the competitive and open electricity market in the United Kingdom and 
supplies customers in all 15 PES areas in Great Britain and Northern Ireland. 
Northern supplies substantially more sites than it had previously supplied 
prior to the beginning of open competition in the supply business in the 
United Kingdom. 

   Northern Supply also competes to supply gas inside and outside its 
authorized area. 

   Northern Utility Services. Northern Utility Services Limited ("Northern 
Utility") is an engineering company whose role is to adapt, maintain and 
restore the distribution network of Northern Distribution and to sell related 
services to third parties. Northern Utility has been able to make significant 
cost reductions for Northern during the past year by working with suppliers 
in order to improve core processes, close selected depot locations, increase 
staff productivity and reduce material and plant costs. Northern Utility has 
pioneered techniques using innovative diagnostic testing equipment which 
reduces the need for intrusive maintenance. The equipment can identify some 
of the causes of potential systems failures before breakdown and subsequent 
loss of supply occurs. Also, the continued development in the use of 
trenchless technology has brought both financial and environmental benefits 
to Northern and its customers. While Northern Utility's largest customer is 
Northern Distribution, it currently sells an average of approximately 16% of 
its services to third parties. Northern Utility is Northern's largest 
employer. 

   Northern Electric Retail Limited. Northern Electric Retail Limited 
("Northern Retail"), a subsidiary of Northern, sells electrical and gas 
appliances and provides account collection and customer services for 
Northern's other businesses.

    Northern Electric Generation Limited. Northern Electric Generation 
Limited ("Northern Generation"), a subsidiary of Northern, focuses on 
electricity generation, primarily through its 15.4% stock ownership in 
Teesside Power Limited, a company that owns and operates a 1,875 MW combined 
cycle gas-fired power station. Northern takes 400 MW of electricity from the 
plant pursuant to a 15 year contract. Northern Generation has also developed 
two 50 MW independent gas fired generation projects. 

   Northern Metering Services Limited. Northern Metering Services Limited 
("Northern Metering"), a subsidiary of Northern, provides meter supply, 
installation, refurbishment and certification services as well as meter 
operator and data collection services. Northern Metering has developed an 
energy profiling system which helps businesses reduce costs through the more 
efficient use of all fuels, not just electricity. 

                 The United Kingdom Deregulated Energy Market 

   General. The electricity industry in the United Kingdom has been 
progressively deregulated since the privatization of electric supply and 
distribution in 1990. The Electricity Act of 1989 established an industry 
structure that permitted this phased-in privatization to occur. Since that 
time, in England and Wales, electricity is produced by generators, the 
largest of which are National Power, PowerGen, Eastern and British Energy. 
Electricity is transmitted through the national grid transmission system by 
The National Grid Company plc ("NGC") and distributed to customers by the 
twelve regional electric companies ("RECs") in their respective authorized 
areas. Most customers currently are supplied with electricity by their local 
REC, although there are other suppliers holding second tier supply licenses, 
including other generators and RECs, who can compete to supply larger 
customers in that REC's authorized area. Under the current licensing regime, 
from September 1998 progressively, competition will be extended to include 
customers who are currently Franchise Supply Customers, who will be free to 
choose their electricity supplier. 

   Virtually all electricity generated in England and Wales is sold by 
generators and bought by suppliers through the Pool. A generator that is a 
Pool member and also a licensed supplier must nevertheless sell all the 
electricity it generates into the Pool, and purchase all the electricity that 
it supplies from the Pool. Because Pool prices fluctuate, generators and 
suppliers may enter into bilateral arrangements, such as contracts for 
differences ("CFDs"), to provide a degree of protection against such 
fluctuations. 

   Distribution. Each of the RECs is required to offer terms for connection 
to its distribution system to any person, for use of its distribution system 
to any authorized electricity operator. In providing use of its distribution 
system, a REC must not discriminate between its own supply business and that 
of any other authorized electricity operator, or between those of other 
authorized electricity operators; nor may its charges differ except where 
justified by differences in cost. 

   Most revenue of the distribution business is controlled by a distribution 
price control formula. The Retail Price Index ("RPI") used in this formula 
reflects the average of the 12 month inflation rates recorded for the 
previous July to December period. The distribution price control formula also 
reflects an XD factor which is established by the Regulator following review 
and is set at 3% from April 1, 1997. This formula determines the maximum 
average price per unit of electricity distributed (in pence per kilowatt 
hour) which a REC is entitled to charge. The distribution price control 
formula permits RECs to partially retain additional revenues due to increased 
distribution of units and a predetermined increase in customer numbers. The 
price control does not seek to constrain the profits of a REC from year to 
year. It is a control on income which operates independently of the REC's 
costs. During the lifetime of the price control additional cost savings 
therefore contribute directly to profit. The distribution prices allowable 
under the current distribution price control formula are expected to be 
reviewed by the Regulator at the expiration of the formula's scheduled 
five-year duration, effective as of April 1, 2000. The formula may be further 
reviewed at other times in the discretion of the Regulator. 

   Supply. Subject to minor exceptions, all electricity customers in the 
United Kingdom must be supplied by a licensed supplier. Licensed suppliers 
purchase electricity and make use of the transmission and distribution 
networks to achieve delivery to customers' premises. 

   There are two types of licensed suppliers: PES (or first tier) suppliers 
and second tier suppliers. PESs are the RECs, Scottish Power and 
Hydro-Electric, each supplying in its respective authorized area. 

                              S-23           
<PAGE>
 Second tier suppliers include National Power, PowerGen, British Energy, 
Scottish Power, Hydro-Electric and other PESs supplying outside their 
respective authorized areas. There are also a number of independent second 
tier suppliers. 

   Until the competitive market fully opens, a Franchise Supply Customer can 
only buy electricity from the PES authorized to supply the relevant 
authorized area. Franchise Supply Customers typically include domestic and 
small commercial and small industrial customers. Non-Franchise Supply 
Customers with demand over 100kW are not limited to buying electricity from 
the local PES and can choose to buy from a second tier supplier. Such 
customers are typically larger commercial, agricultural and industrial 
electricity users. Second tier suppliers compete with one another and with 
the local PES to supply customers in this competitive (or "non-franchise") 
sector of the market. 

   The supply of electricity to domestic and small non-domestic customers is 
subject to price control regulation which effectively limits the tariffs that 
can be charged to such customers and has, in recent years, generally resulted 
in tariff reductions over time. 

   The Pool. The Pool was established at the time of privatization for bulk 
trading of electricity in England and Wales between generators and suppliers. 
The Pool reflects two principal characteristics of the physical generation 
and supply of electricity from a particular generator to a particular 
supplier. First, it is not possible to trace electricity from a particular 
generator to a particular supplier. Second, it is not practicable to store 
electricity in significant quantities, creating the need for a constant 
matching of supply and demand. Subject to certain exceptions, all electricity 
generated in England and Wales must be sold and purchased through the Pool. 
All licensed generators and suppliers must become and remain signatories to 
the Pooling and Settlement Agreement, which governs the constitution and 
operation of the Pool and the calculation of payments due to and from 
generators and suppliers. The Pool also provides centralized settlement of 
accounts and clearing. The Pool does not itself buy or sell electricity. 

   Prices for electricity are set by the Pool daily for each one-half hour of 
the following day based on the bids of the generators and a complex set of 
calculations matching supply and demand and taking account of system 
stability, security and other costs. A computerized system (the settlement 
system) is used to calculate prices and to process metered, operational and 
other data and to carry out the other procedures necessary to calculate the 
payments due under the Pool trading arrangements. The settlement system is 
administered on a day-to-day basis by Energy Settlements and Information 
Services, Limited, a subsidiary of NGC, as settlement system administrator. 

   Suppliers and generators can enter into contracts for differences, which 
act as a hedge against Pool price volatility. Generally, CFDs are contracts 
between generators and suppliers that have the effect of fixing the price of 
electricity for a contracted quantity of electricity over a specific time 
period. Differences between the actual price set by the Pool and the agreed 
prices give rise to difference payments between the parties to the particular 
CFD. At any time, Northern's forecast franchise supply market demand is 
substantially hedged through various types of agreements including CFDs. 

THE BUSINESS OF MIDAMERICAN 

   MidAmerican established in 1997 the framework for a new approach to 
managing its business. Beginning January 1, 1998, MidAmerican began operating 
as four distinct business units: generation, transmission, energy delivery 
and retail. Certain administrative functions are handled by a corporate 
services group which supports all of the business units. Although specific 
functions may be moved between business units as future circumstances 
warrant, the main focus of each business unit has been established. 
Presently, significant functions of the generation business unit include the 
production and purchase of energy and the sale of wholesale energy. The 
transmission business unit coordinates all activities related to 
MidAmerican's transmission facilities, including monitoring access to and 
assuring the reliability of the transmission system. Energy delivery includes 
the distribution of electricity and natural gas to end-users, and related 
activities. Retail includes marketing, customer service and related functions 
for core and complementary products and services. 

   MidAmerican is an exempt public utility holding company headquartered in 
Des Moines, Iowa, and incorporated in the state of Iowa. MidAmerican's 
strategy is to become the leading regional provider of 

                              S-24           
<PAGE>
 energy and complementary services. MidAmerican's interests include 100% of 
the common stock of MidAmerican Energy Company, MidAmerican Capital and 
Midwest Capital and 95% of the common stock of MidAmerican Realty Services. 
MidAmerican Energy Company is primarily engaged in the business of 
generating, transmitting, distributing and selling electric energy and in 
distributing, selling and transporting natural gas. MidAmerican Capital 
manages marketable securities and passive investment activities, nonregulated 
wholesale and retail natural gas businesses, security services and other 
energy-related, nonregulated activities. Midwest Capital functions as a 
regional business development company in MidAmerican's service territory. In 
an effort that began in 1996, MidAmerican is continuing to redeploy 
investments and to invest in other lines of business that support its 
strategy. For example, MidAmerican Realty Services, with over 4,000 sales 
agents and 895 employees in six states, offers integrated real estate 
services including residential brokerage, relocation, title and abstract 
services. On a consolidated basis, the real estate brokerage operations rank 
third in the nation and MidAmerican believes these operations will provide a 
strategically important customer access point and an advertising and 
"branding" vehicle as energy markets deregulate, in addition to being 
profitable businesses on a stand-alone basis. 

   For the year ended December 31, 1997, 86.5% of MidAmerican's operating 
revenues were from MidAmerican Energy Company, 13.4% were from MidAmerican 
Capital and 0.1% were from Midwest Capital. 

   MidAmerican distributes electric energy in Council Bluffs, Des Moines, 
Fort Dodge, Iowa City, Sioux City and Waterloo, Iowa, the Quad Cities 
(Davenport and Bettendorf, Iowa and Rock Island, Moline and East Moline, 
Illinois) and a number of adjacent communities and areas. MidAmerican 
distributes natural gas in Cedar Rapids, Des Moines, Fort Dodge, Iowa City, 
Sioux City and Waterloo, Iowa; the Quad Cities; Sioux Falls, South Dakota; 
and a number of adjacent communities and areas. As of December 31, 1997, 
MidAmerican had 647,700 retail electric customers and 618,000 retail natural 
gas customers. 

   MidAmerican's electric and gas operations are conducted under franchises, 
certificates, permits and licenses obtained from state and local authorities. 
The franchises, with various expiration dates, are typically for 25-year 
terms. 

   MidAmerican has a residential, agricultural, commercial and diversified 
industrial customer group, in which no single industry or customer accounted 
for more than 3.8% (food and kindred products industry) of its total 1997 
electric operating revenues or 3.7% (food and kindred products industry) of 
its total 1997 gas operating margin. Among the primary industries served by 
MidAmerican are those which are concerned with the manufacturing, processing 
and fabrication of primary metals, real estate, food products, farm and other 
non-electrical machinery, and cement and gypsum products. 

   For the year ended December 31, 1997, MidAmerican derived approximately 
68% of its gross operating revenues from its electric business and 32% from 
its gas business. For 1996 and 1995, the corresponding percentages were 67% 
electric and 33% gas, and 70% electric and 30% gas, respectively.

   There are seasonal variations in MidAmerican's electric and gas businesses 
which are principally related to the use of energy for air conditioning and 
heating. In 1997, 38% of MidAmerican's electric revenues were reported in the 
months of June, July, August and September, reflecting the use of electricity 
for cooling, and 54% of MidAmerican's gas revenues were reported in the 
months of January, February, March and December, reflecting the use of gas 
for heating. 

MidAmerican Electric Operations 

   The annual hourly peak demand on MidAmerican's electric system occurs 
principally as a result of air conditioning use during the cooling season. 
MidAmerican's highest hourly peak demand in 1997 was 3,548 MW, which was 5 MW 
less than MidAmerican's record hourly peak of 3,553 MW set in 1995. 

   MidAmerican's accredited 1997 summer net generating capability was 4,293 
MW. Accredited net generating capability represents the amount of 
Company-owned generation available to meet the requirements on MidAmerican's 
energy system, net of the effect of participation purchases and sales. The 
net generating capability at any time may be less due to regulatory 
restrictions, fuel restrictions and generating units being temporarily out of 
service for inspection, maintenance, refueling or modifications. 

   MidAmerican is interconnected with certain Iowa and neighboring utilities 
and is involved in an electric power pooling agreement known as MAPP. MAPP is 
a voluntary association of electric utilities doing business in Iowa, 
Minnesota, Nebraska and North Dakota and portions of Montana, South Dakota 
and Wisconsin and the Canadian provinces of Saskatchewan and Manitoba. Its 
membership also includes power marketers, regulatory agencies and independent 
power producers. MAPP facilitates operation of the transmission system, 
serves as a power and energy market clearing house and is responsible for the 
safety and reliability of the bulk electric system.

 (2)    Actual MW may vary depending on operating and reservoir conditions 
        and plant design. Facility Net Capacity (in MW) represents facility 
        gross capacity (in MW) less parasitic load. Parasitic load is 
        electrical output used by the facility and not made available for 
        sale to utilities or other outside purchasers. Net MW owned indicates 
        current legal ownership, but, in some cases, does not reflect the

                        DESCRIPTION OF THE SECURITIES 

   The following description of the particular terms of the Securities 
supplements and, to the extent inconsistent therewith, replaces the 
description of the general terms of the Debt Securities set forth under the 
heading "Description of Debt Securities" in the accompanying Prospectus. The 
following description does not purport to be complete and is qualified in its 
entirety by reference to the description in the accompanying Prospectus and 
to the instruments referred to therein. The Securities will be issued 
pursuant to an Indenture dated as of October 15, 1997, as supplemented by a 
Second Supplemental Indenture to be dated as of September 22, 1998, between 
CalEnergy and IBJ Schroder Bank & Trust Company, as trustee (the "Trustee") 
(as so supplemented, the "Indenture"). The Indenture is referred to in the 
Prospectus as the "Senior Debt Indenture." The Securities are "Senior Debt 
Securities" as that term is used in the Prospectus and are also referred to 
in the Prospectus as the "Offered Debt Securities." Provisions of the Senior 
Note Indenture are more fully described under the caption "Description of 
Debt Securities" in the accompanying Prospectus. Capitalized words not 
defined herein are used as defined in the accompanying Prospectus. 

GENERAL 

   The Securities will be senior unsecured obligations of CalEnergy, will 
rank pari passu with all other senior unsecured indebtedness of CalEnergy, 
and will be limited to $1,400,000,000 in aggregate principal amount. 

   The 2003 Notes will bear interest at the rate of 6.96% per annum and will 
mature on September 15, 2003. The 2005 Notes will bear interest at the rate 
of 7.23% per annum and will mature on September 15, 2005. The 2008 Notes will 
bear interest at the rate of 7.52% per annum and will mature on September 15, 
2008. The Bonds will bear interest at the rate of 8.48% per annum and will 
mature on September 15, 2028. Interest on the Securities will be payable 
semi-annually in arrears on each March 15 and September 15, commencing March 
15, 1999, to the Holders thereof at the close of business on the preceding 
March 1 and September 1, respectively. Interest on the Securities will be 
computed on the basis of a 360-day year of twelve 30-day months. 

   The Securities will be issued without coupons and in fully registered form 
only in denominations of $1,000 and integral multiples thereof. 

   CalEnergy is subject to the informational reporting requirements of 
Sections 13 and 15(d) under the Exchange Act and, in accordance therewith, 
files certain reports and other information with the Commission. See 
"Available Information" in the accompanying Prospectus. In addition, if 
Sections 13 and 15(d) cease to apply to CalEnergy, CalEnergy will covenant in 
the Indenture to file comparable reports and information with the Trustee and 
the Commission, and mail such reports and information to holders of 
Securities at their registered addresses, for so long as any Securities 
remain outstanding. 

OPTIONAL REDEMPTION 

   The Securities are subject to optional redemption, in whole or in part, 
pro rata at par plus accrued interest to the redemption date plus a premium 
calculated to "make whole" to comparable U.S. Treasury securities plus (i) 25 
basis points in the case of the 2003 Notes, (ii) 37.5 basis points in the 
case of the 2005 Notes, (iii) 37.5 basis points in the case of the 2008 Notes 
and (iv) 50 basis points in the case of the Bonds. 

SINKING FUND 

   The Securities will not be subject to any mandatory sinking fund. 

RANKING 

   The Securities will be general, unsecured senior obligations of CalEnergy 
and will rank pari passu in right of payment with all other existing and 
future senior unsecured obligations of CalEnergy and senior in right of 
payment to all existing and, to the extent permitted under the Indenture, 
future subordinated indebtedness of CalEnergy. The Securities will be 
effectively subordinated to all existing and future secured indebtedness of 
CalEnergy and to all indebtedness and other liabilities of CalEnergy's 
subsidiaries, projects and joint ventures to the extent of the assets of such 
entities. At June 30, 1998, on a pro forma basis, after giving effect to the 
MidAmerican Merger, the Equity Offering, the Non-Recourse 

                              S-29           
<PAGE>
 Financing, and the Securities Offering and the use of the net proceeds 
therefrom, CalEnergy would have had $200 million of secured limited recourse 
parent company indebtedness (of which $0 is currently recourse to CalEnergy) 
and approximately $5,033 million of indebtedness that represented the 
Company's proportionate share of project and joint venture and subsidiary 
debt, all such debt would be effectively senior to the Securities, and 
approximately $575 million of indebtedness that would be pari passu with the 
Securities. See "Capitalization." 

CHANGE IN COVENANTS WHEN SECURITIES RATED INVESTMENT GRADE 

   Following the first date upon which the Securities are rated Baa3 or 
better by Moody's Investors Service, Inc., BBB-or better by Standard & Poor's 
Corporation and BBB-or better by Duff & Phelps Credit Rating Co. (or, in any 
case, if such person ceases to rate the Securities for reasons outside the 
control of the Company, the equivalent investment grade credit rating from 
any other "nationally recognized statistical rating organization" (within the 
meaning of Rule 15c3-1(c)(2)(vi)(F) under the Securities Exchange Act of 
1934) selected by the Company as a replacement rating agency) (the "Rating 
Event Date") (and provided no Event of Default or event which with notice or 
passage of time would constitute an Event of Default shall exist on the 
Rating Event Date), the provisions described under "Mergers, Consolidations 
and Sales of Assets" in the Prospectus and the covenants specifically listed 
and described under "Certain Covenants" in the accompanying Prospectus (other 
than "--Purchase of Debt Securities Upon a Change in Control" in the 
accompanying Prospectus) will no longer be applicable to the Securities and 
in their place the covenants and provisions described below under 
"Restrictions on Liens" and "Consolidation, Merger, Sale of Assets" will be 
applicable. There can be no assurance that a Rating Event Date will occur or, 
if one occurs, that the Securities will continue to maintain an investment 
grade rating. In the event that subsequent to a Rating Event Date an Event of 
Default or event which with notice or passage of time would constitute an 
Event of Default shall exist with respect to the Securities or the Securities 
shall thereafter be rated less than Baa3 by Moody's Investors Service, Inc., 
less than BBB-by Standard & Poor's Corporation and less than BBB-by Duff & 
Phelps Credit Rating Co. (or such other rating agency selected by the Company 
as aforesaid) the provisions and covenants contained in the Indenture at the 
time of the issuance of the Securities that cease to be applicable after the 
Rating Event Date will not be reinstated. See "Description of Debt 
Securities--Certain Covenants" in the accompanying Prospectus. 

  Restrictions on Liens 

   Following the Rating Event Date and so long as any of the Securities are 
outstanding, CalEnergy shall not pledge, mortgage, hypothecate or permit to 
exist any mortgage, pledge or other lien upon any property or assets at any 
time directly owned by CalEnergy to secure any indebtedness for money 
borrowed which is incurred, issued, assumed or guaranteed by CalEnergy 
("Indebtedness"), without making effective provisions whereby the Securities 
shall be equally and ratably secured with any and all such Indebtedness and 
with any other Indebtedness similarly entitled to be equally and ratably 
secured; provided however, that this restriction shall not apply to or 
prevent the creation or existence of: (i) liens existing on the Rating Event 
Date; (ii) purchase money liens which do not exceed the cost or value of the 
purchased property or assets; (iii) liens not to exceed 10% of Consolidated 
Net Tangible Assets and (iv) liens on property or assets granted in 
connection with extending, renewing, replacing or refinancing in whole or in 
part the Indebtedness (including, without limitation, increasing the 
principal amount of such Indebtedness) secured by liens described in the 
foregoing clauses (i) through (iii), provided that the liens in connection 
with any such extension, renewal, replacement or refinancing will be limited 
to the specific property or assets that was subject to the original lien. 

   In the event that CalEnergy shall propose to pledge, mortgage or 
hypothecate or permit to existing any pledge, mortgage or other lien upon any 
property or assets at any time directly owned by it to secure any 
Indebtedness, other than as permitted by clauses (i) through (iv) of the 
previous paragraph CalEnergy will give prior written notice thereof to the 
Trustee and CalEnergy will, prior to or simultaneously with such pledge, 
mortgage or hypothecation, effectively secure all the Securities equally and 
ratably with such Indebtedness. 

   The foregoing covenant will not restrict the ability of CalEnergy's 
Subsidiaries and Affiliates to pledge, mortgage, hypothecate or permit to 
exist any mortgage, pledge or lien upon their property or assets, in 
connection with project financings or otherwise. 

                              S-30           
<PAGE>
   Consolidation, Merger, Sale of Assets 

   Following the Rating Event Date, and so long as any of the Securities are 
outstanding, CalEnergy shall not consolidate with or merge with or into any 
other Person, or convey, transfer or lease its consolidated properties and 
assets substantially as an entirety to any Person, or permit any Person to 
merge into or consolidate with CalEnergy, unless (i) CalEnergy is the 
surviving or continuing corporation or the surviving or continuing 
corporation or purchaser or lessee is a corporation incorporated under the 
laws of the United States of America, one of the States thereof or the 
District of Columbia or Canada and assumes CalEnergy's obligations under the 
Securities and under the Indenture and (ii) immediately before and after such 
transaction, no Event of Default shall have occurred and be continuing. 

   Except for a sale of the consolidated properties and assets of CalEnergy 
substantially as an entirety as provided above, and other than properties or 
assets required to be sold to conform with laws or governmental regulations, 
CalEnergy will not be permitted, directly or indirectly, to sell or otherwise 
dispose of any of its consolidated properties or assets (other than 
short-term, readily marketable investments purchased for cash management 
purposes with funds not representing the proceeds of other asset sales) if on 
a pro forma basis, the aggregate net book value of all such sales during the 
most recent 12-month period would exceed 10% of Consolidated Net Tangible 
Assets computed as of the end of the most recent quarter preceding such sale; 
provided, however, that any such sales shall be disregarded for purposes of 
this 10% limitation if the net proceeds are invested in properties or assets 
in similar or related lines of business of CalEnergy and its Subsidiaries 
and, provided further, that CalEnergy may sell or otherwise dispose of 
consolidated properties and assets in excess of such 10% limitation if the 
net proceeds from such sales or dispositions, which are not reinvested as 
provided above, are retained by CalEnergy as cash or Cash Equivalents or used 
to retire Indebtedness of CalEnergy (other than Indebtedness which is 
subordinated to the Securities) and its Subsidiaries. 

  Events of Default / Change of Control 

   After the Rating Event Date, the Events of Default and Change of Control 
provisions described in the Prospectus will continue to be applicable to the 
Securities. See "Description of Debt Securities--Events of Default" and 
"Certain Covenants--Purchase of Debt Securities Upon a Change of Control" in 
the accompanying Prospectus. 

  Certain Defined Terms 

   "Consolidated Net Tangible Assets" means, as of the date of any 
determination thereof, the total amount of all assets of the Company 
determined on a consolidated basis in accordance with GAAP as of such date 
less the sum of (a) the consolidated current liabilities of the Company 
determined in accordance with GAAP and (b) assets properly classified as 
Intangible Assets. 

   "Intangible Assets" means, as of the date of determination thereof, all 
assets of the Company properly classified as intangible assets determined on 
a consolidated basis in accordance with GAAP. 

GLOBAL SECURITIES 

   The Securities will be issued in the form of Global Securities deposited 
with, or on behalf of, the Depositary and registered in the name of a nominee 
of the Depositary. Except under the limited circumstances described in the 
Prospectus under the caption "Book-Entry System," owners of beneficial 
interests in the Global Securities will not be entitled to physical delivery 
of the Securities in certificated form. The Global Securities may not be 
transferred except as a whole by the Depositary to a nominee of the 
Depositary or by a nominee of the Depository to the Depositary or another 
nominee of the Depository or by the Depositary or any nominee to a successor 
of the Depositary or a nominee of such successor. 

   A further description of the Depositary's procedures with respect to the 
Global securities is set forth in the Prospectus under the caption 
"Book-Entry System."

</TABLE>

   The Underwriting Agreement provides that the obligations of the 
Underwriters to purchase the Notes are subject to the approval of certain 
legal matters by counsel and to certain other conditions and that if any of 
the Securities are purchased by the Underwriters pursuant to the Underwriting 
Agreement, all of the Securities agreed to be purchased by the Underwriters 
pursuant to the Underwriting Agreement must be so purchased. 

   The Company has been advised by the Underwriters that they propose to 
offer the Securities offered hereby directly to the public initially at the 
public offering prices set forth on the cover page of this Prospectus 
Supplement. After the initial offering to the public, the offering price may 
be changed. 

   The Company has agreed to indemnify the Underwriters against certain 
liabilities, including liabilities under the Securities Act, and to 
contribute to payments which the Underwriters may be required to make in 
respect thereof. 

   The Securities are new securities for which there currently is no market. 
The Company does not intend to apply for listing of the Securities on any 
securities exchange. Although each Underwriter has advised the Company that 
it presently intends to make a market in the Securities, none of the 
Underwriters is obligated to do so and any such market-making activities may 
be discontinued at any time without notice in the sole discretion of each of 
the Underwriters. Accordingly, no assurance can be given as to the 
development or liquidity of any market for the Securities, or, if a market 
does develop, at what prices the Securities will trade. If the Underwriters 
cease to act as market makers for the Securities for any reason, there can be 
no assurance that another firm or person will make a market in the 
Securities. 

   Each of the Underwriters and their affiliates have provided from time to 
time, and expect to provide in the future, various investment banking and 
commercial banking services for the Company, for which such Underwriters have 
received and will receive customary fees and commissions. In addition, the 
Underwriters also acted as financial advisors to the Company in connection 
with the MidAmerican Merger. 

   Until the distribution of the Securities is completed, rules of the 
Securities and Exchange Commission may limit the ability of the Underwriters 
to bid for and purchase Securities. As an exception to these rules, the 
Underwriters are permitted to engage in certain transactions that stabilize 
the price of the Securities. Such transactions may consist of bids or 
purchases for the purpose of pegging, fixing or maintaining the price of the 
Securities. 

   In addition, if the Underwriters over-allot (i.e., if they sell more 
Securities than are set forth on the cover page of this Prospectus 
Supplement), and thereby create a short position in the Securities in 
connection with the offering, the Underwriters may reduce that short position 
by purchasing Securities in the open market. 

   In general, purchases of a security for the purpose of stabilization or to 
reduce a syndicate short position could cause the price of the security to be 
higher than it might otherwise be in the absence of such purchases. 

   Neither the Company nor any of the Underwriters makes any representation 
or prediction as to the direction or magnitude of any effect that the 
transactions described above may have on the price of the Securities. In 
addition, neither the Company nor any of the Underwriters makes any 
representation that the Underwriters will engage in such transactions or that 
such transactions, once commenced, will not be discontinued without notice.

                         NOTICE TO CANADIAN RESIDENTS 

RESALE RESTRICTIONS 

   The distribution of the Securities in Canada is being made only on a 
private placement basis exempt from the requirement that the Company prepare 
and file a prospectus with the securities regulatory authorities in each 
province where trades of Securities are effected. Accordingly, any resale of 
the Securities in Canada must be made in accordance with applicable 
securities laws which will vary depending on the relevant jurisdiction, and 
which may require resales to be made in accordance with available statutory 
exemptions or pursuant to a discretionary exemption granted by the applicable 
Canadian securities regulatory authority. Purchasers are advised to seek 
legal advice prior to any resale of the Securities. 

REPRESENTATIONS OF PURCHASERS 

   Each purchaser of Securities in Canada who receives a purchase 
confirmation will be deemed to represent to the Company and the dealer from 
whom such purchase confirmation is received that (i) such purchaser is 
entitled under applicable provincial securities laws to purchase such 
Securities without the benefit of a prospectus qualified under such 
securities laws, (ii) where required by law, that such purchaser is 
purchasing as principal and not as agent, and (iii) such purchaser has 
reviewed the text above under "Resale Restrictions." 

RIGHTS OF ACTION (ONTARIO PURCHASERS) 

   The securities being offered are those of a foreign issuer and Ontario 
purchasers will not receive the contractual right of action prescribed by 
section 32 of the Regulation under the Securities Act (Ontario). As a result,

   The consolidated financial statements and financial statement schedules of 
the Company and its subsidiaries as of December 31, 1997 and 1996 and for 
each of the three years in the period ended December 31, 1997 included in 
this Prospectus Supplement have been audited by Deloitte & Touche LLP, 
independent auditors, as stated in their reports appearing in this Prospectus 
Supplement and incorporated herein by reference and are so included in 
reliance upon the reports of such firm given upon their authority as experts 
in accounting and auditing. 

   With respect to the Company's unaudited interim financial information for 
the periods ended March 31, 1998 and 1997 and June 30, 1998 and 1997, 
included and incorporated by reference in this Prospectus Supplement, 
Deloitte & Touche LLP have applied limited procedures in accordance with

in their reports included in the Company's Quarterly Reports on Form 10-Q for 
the quarters ended March 31, 1998 and June 30, 1998, and included herein, 
they did not audit and they do not express an opinion on that interim 
financial information. Accordingly, the degree of reliance on their reports 
on such information should be restricted in light of the limited nature of 
the review procedures applied. Deloitte & Touche LLP are not subject to the 
liability provisions of Section 11 of the Securities Act for their reports on 
the unaudited interim financial information because those reports are not 
"reports" or a "part" of the Registration Statement prepared or certified by 
an accountant within the meaning of Sections 7 and 11 of the Securities Act.

                         INDEPENDENT AUDITORS' REPORT 

Board of Directors and Shareholders 
CalEnergy Company, Inc. 
Omaha, Nebraska 

   We have audited the accompanying consolidated balance sheets of CalEnergy 
Company, Inc. and subsidiaries as of December 31, 1997 and 1996, and the 
related consolidated statements of operations, stockholders' equity and cash 
flows for each of the three years in the period ended December 31, 1997. 
These financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these financial 
statements based on our audits. 

   We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion. 

   In our opinion, such consolidated financial statements present fairly, in 
all material respects, the financial position of CalEnergy Company, Inc. and 
subsidiaries at December 31, 1997 and 1996 and the results of their 
operations and their cash flows for each of the three years in the period 
ended December 31, 1997, in conformity with generally accepted accounting 
principles.

      Dollars, Pounds and Shares in Thousands, Except Per Share Amounts 

1. BUSINESS 

   CalEnergy Company, Inc. (the "Company") is a United States-based global 
power company which generates, distributes and supplies electricity to 
utilities, government entities, retail customers and other customers located 
throughout the world. The Company was founded in 1971 and through its 
subsidiaries is primarily engaged in the development, ownership and operation 
of environmentally responsible independent power production facilities 
worldwide utilizing geothermal, natural gas, hydroelectric and other energy 
sources. In addition, the Company is engaged in the distribution and supply 
of electricity to approximately 1.5 million customers primarily in northeast 
England as well as the generation and supply of electricity (together with 
other related business activities) throughout England and Wales. The Company 
is also active in supplying gas and has applications for over 400,000 
customers in those areas of England, Wales and Scotland where retail gas 
competition has been introduced. 

   The Company has organized several partnerships and joint ventures (herein 
referred to as the "Coso Joint Ventures") in order to develop geothermal 
energy at the China Lake Naval Air Weapons Station, Coso Hot Springs, China 
Lake, California. Collectively, the projects undertaken by these Coso Joint 
Ventures are referred to as the Coso Project. In 1992, the Company entered 
into the natural gas-fired electrical generation market through the purchase 
of a development opportunity in Yuma, Arizona which commenced commercial 
operation in May 1994. In 1993, the Company started developing a number of 
international power project opportunities where private power generating 
programs have been initiated, including the Philippines and Indonesia. In 
1995, the Company acquired Magma Power Company ("Magma"). Magma's operating 
assets included four projects referred to as the Partnership Project in which 
Magma had a 50% interest, and three projects referred to as the Salton Sea 
Project of which Magma owned 100%. A fourth project included in the Salton 
Sea Project was constructed after the acquisition of Magma and commenced 
operations in June 1996. In addition, in April 1996, the Company acquired the 
remaining 50% interest in the Partnership Project. In August 1996, the 
Company acquired Falcon Seaboard Resources, Inc. ("Falcon Seaboard") which 
includes significant interests in three operating gas-fired cogeneration 
facilities and a related natural gas pipeline. On December 24, 1996, CE 
Electric UK plc ("CE Electric"), which in 1997 was 70% owned indirectly by 
the Company and 30% owned indirectly by Peter Kiewit Sons', Inc. ("PKS"), 
acquired majority ownership of the outstanding ordinary share capital of 
Northern Electric plc ("Northern") pursuant to a tender offer ("Tender 
Offer"). As of March 18, 1997, CE Electric effectively owned 100% of Northern 
ordinary shares. 

   Northern is one of the twelve regional electricity companies ("RECs") 
which came into existence as a result of the restructuring and subsequent 
privatization of the electricity industry in the United Kingdom in 1990. 
Northern is primarily engaged in the distribution and supply of electricity. 
Northern was granted a Public Electricity Supply ("PES") license under the 
Electricity Act to supply electricity in Northern's Authorized Area 
("Authorized Area"). Northern's Authorized Area covers approximately 14,400 
square kilometers with a population of approximately 3.2 million people and 
includes the counties of Northumberland, Tyne and Wear, Durham, Cleveland and 
North Yorkshire. Northern supplies electricity outside its Authorized Area 
pursuant to second tier licenses. Northern also is involved in non-regulated 
activities, including the supply of gas within England, Wales and Scotland, 
the generation of electricity, electrical appliance retailing and gas 
exploration and production. 

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

   The consolidated financial statements include the accounts of the Company, 
its wholly-owned subsidiaries, and its proportionate share of the 
partnerships and joint ventures in which it has an undivided interest in the 
assets and is proportionally liable for its share of liabilities. Other 
investments and corporate joint ventures where the Company has the ability to 
exercise significant influence are accounted for under the equity method of 
accounting. Investments, where the Company's ability to 

                               F-7

           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

influence is limited, are accounted for under the cost method of accounting. 
All significant inter-enterprise transactions and accounts have been 
eliminated. The results of operations of the Company include the Company's 
proportionate share of results of operations of entities acquired as of the 
date of each acquisition. 

CASH EQUIVALENTS, INVESTMENTS AND RESTRICTED CASH 

   The Company considers all investment instruments purchased with an 
original maturity of three months or less to be cash equivalents. Restricted 
cash is not considered a cash equivalent. 

   Investments other than restricted cash are primarily commercial paper and 
money market securities. The restricted cash balance includes such securities 
and mortgage backed securities, and is mainly composed of amounts deposited 
in restricted accounts from which the Company will source its equity 
contributions and debt service reserve requirements relating to the projects. 
These funds are restricted by their respective project debt agreements to be 
used only for the related project. 

   At December 31, 1997, all of the Company's investments are classified as 
held-to-maturity and are accounted for at their amortized cost basis. The 
carrying amount of the investments approximates the fair value based on 
quoted market prices as provided by the financial institution which holds the 
investments. 

PROPERTIES, PLANTS, CONTRACTS, EQUIPMENT AND DEPRECIATION 

   The cost of major additions and betterments are capitalized, while 
replacements, maintenance, and repairs that do not improve or extend the 
lives of the respective assets are expensed. 

   Depreciation of the operating power plant costs, net of salvage value, is 
computed on the straight line method over the estimated useful lives, between 
10 and 30 years. Depreciation of furniture, fixtures and equipment which are 
recorded at cost, is computed on the straight line method over the estimated 
useful lives of the related assets, which range from three to ten years. 

   The Northern, Falcon Seaboard, Partnership Interest and Magma acquisitions 
by the Company have been accounted for as purchase business combinations. All 
identifiable assets acquired and liabilities assumed were assigned a portion 
of the cost of acquiring the respective companies equal to their fair values 
at the date of the acquisition and include the following: 

     Property and equipment of Northern is depreciated using a systematic 
   method, which approximates the straight line method over the estimated 
   useful lives of the related assets which range from 3-40 years. 

     Power sales agreements are amortized separately over (1) the remaining 
   portion of the scheduled price periods of the power sales agreements and 
   (2) for the Partnership Interest and Magma acquisitions the 20 year 
   avoided cost periods of the power sales agreements using the straight line 
   method. 

   Capitalized costs for gas reserves, other than costs of unevaluated 
exploration projects and projects awaiting development consent, are depleted 
using the unit of production method. Depletion is calculated based on 
hydrocarbon reserves of properties in the evaluated pool estimated to be 
commercially recoverable and include anticipated future development costs in 
respect of those reserves. 

   Expenditures on major information technology systems are capitalized and 
depreciated on a straight line basis over the useful life of the developed 
systems which range from 3-10 years. 

WELL, RESOURCE DEVELOPMENT AND EXPLORATION COSTS 

   The Company follows the full cost method of accounting for costs incurred 
in connection with the exploration and development of geothermal and natural 
gas resources. All such costs, which include dry 

                               F-8           
<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

hole costs and the cost of drilling and equipping production wells and 
directly attributable administrative and interest costs, are capitalized and 
amortized over their estimated useful lives when production commences. The 
estimated useful lives of production wells are ten to twenty years depending 
on the characteristics of the underlying resource; exploration costs and 
development costs, other than production wells, are generally amortized over 
the weighted average remaining term of the Company's power and steam purchase 
contracts. 

EXCESS OF COST OVER FAIR VALUE 

   Total acquisition costs in excess of the fair values assigned to the net 
assets acquired are amortized over a 40 year period for the Northern and 
Magma acquisitions and a 25 year period for the Falcon Seaboard acquisition, 
both using the straight line method. 

IMPAIRMENT OF LONG-LIVED ASSETS 

   The Company reviews long-lived assets and certain identifiable intangibles 
for impairment whenever events or changes in circumstances indicate that the 
carrying amount of an asset may not be recoverable. An impairment loss would 
be recognized whenever evidence exists that the carrying value is not 
recoverable. 

DEFERRED WELL AND REWORK COSTS 

   Well rework costs are deferred and amortized over the estimated period 
between reworks. These deferred costs, net of accumulated amortization, are 
$5,421 and $8,371 at December 31, 1997 and 1996, respectively, and are 
included in other assets. 

REVENUE RECOGNITION 

   Revenues are recorded based upon service rendered and electricity and 
steam delivered, distributed or supplied to the end of the month. Where there 
is an overrecovery of supply or distribution business revenues against the 
maximum regulated amount, revenues are deferred equivalent to the 
overrecovered amount. The deferred amount is deducted from revenue and 
included in other liabilities. Where there is an underrecovery, no 
anticipation of any potential future recovery is made. 

CAPITALIZATION OF INTEREST AND DEFERRED FINANCING COSTS 

   Prior to the commencement of operations, interest is capitalized on the 
costs of the plants and geothermal resource development to the extent 
incurred. Capitalized interest and other deferred charges are amortized over 
the lives of the related assets. 

   Deferred financing costs are amortized over the term of the related 
financing using the effective interest method. 

DEFERRED INCOME TAXES 

   The Company recognizes deferred tax assets and liabilities based on the 
difference between the financial statement and tax bases of assets and 
liabilities using estimated tax rates in effect for the year in which the 
differences are expected to reverse. The Company intends to repatriate 
earnings of foreign subsidiaries in the foreseeable future. As a result, 
deferred income taxes are provided for retained earnings of international 
subsidiaries and corporate joint ventures which are intended to be remitted. 

FAIR VALUES OF FINANCIAL INSTRUMENTS 

   The following methods and assumptions were used by the Company in 
estimating fair values of financial instruments as discussed herein. Fair 
values have been estimated based on quoted market prices for debt issues 
listed on exchanges. Fair values of financial instruments that are not 
actively traded are based on market prices of similar instruments and/or 
valuation techniques using market assumptions. 

                               F-9           
<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

    The Company assumes that the carrying amount of short-term financial 
instruments approximates their fair value. For these purposes, short-term is 
defined as any item that matures, reprices, or represents a cash transaction 
between willing parties within six months or less of the measurement date. 

PENSIONS 

   Northern contributes to the Electricity Supply Pension Scheme and 
contributions to the scheme are charged to the income statement. The capital 
cost of ex gratia and supplementary pensions are normally charged to the 
income statement in the period in which they are granted. Variations in 
pension cost, which are identified as a result of actuarial 
valuations/reviews, are amortized over the average expected remaining working 
lives of employees in proportion to their expected payroll costs. Differences 
between the amounts funded and the amounts charged to the profit and loss 
account are treated as either provisions or prepayments in the balance sheet. 

NET INCOME PER COMMON SHARE 

   In February 1997, the Financial Accounting Standards Board ("FASB") 
adopted Statement of Financial Accounting Standards ("SFAS") No. 128, 
"Earnings per Share." SFAS 128 replaced primary and fully diluted earnings 
per share with basic and diluted earnings per share, respectively. 

   Basic and diluted earnings per common share are based on the weighted 
average number of common shares outstanding during the period. Diluted 
earnings per common share also assumes the conversion of the convertible 
preferred securities of subsidiary trusts, when dilutive, and the exercise of 
all dilutive stock options outstanding at their option prices, with the 
option exercise proceeds and tax benefits used to repurchase shares of common 
stock at the average market price using the treasury stock method. 

   A reconciliation of basic earnings per share before extraordinary item to 
diluted earnings per share before extraordinary item follows:

RECLASSIFICATION 

   Certain amounts in the fiscal 1996 and 1995 financial statements and 
supporting footnote disclosures have been reclassified to conform to the 
fiscal 1997 presentation. Such reclassification did not impact previously 
reported net income or retained earnings.

           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

 USE OF ESTIMATES 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenues and expenses during the 
reporting period. Actual results could differ from those estimates. 

NEW ACCOUNTING PRONOUNCEMENTS 

   In June 1997, the FASB adopted SFAS No. 130, "Reporting Comprehensive 
Income", and No. 131, "Disclosures about Segments of an Enterprise and 
Related Information". SFAS 130 establishes standards for reporting and 
display of comprehensive income and its components in a full set of general 
purpose financial statements. SFAS 131 redefines how operating segments are 
determined and requires disclosure of certain financial and descriptive 
information about a company's operating segments. Both statements will be 
effective for the Company beginning January 1, 1998. The Company has not yet 
determined the impact of these statements on current disclosures. 

3. KDG ACQUISITION 

   On September 11, 1997, the Company signed a definitive agreement with 
Kiewit Diversified Group ("KDG"), a wholly owned subsidiary of PKS, for the 
Company to purchase KDG's ownership interest in various project partnerships 
and CalEnergy common shares (the "KDG Acquisition"). Accordingly, common 
stock and options subject to redemption have been reclassified in the 
consolidated balance sheet. 

   KDG's ownership interest in CalEnergy comprised approximately 20,231 
shares of common stock (assuming exercise by KDG of one million options to 
purchase CalEnergy shares), the 30% interest in Northern Electric, as well as 
the following minority project interests: Mahanagdong (45%), Casecnan (35%), 
Dieng (47%), Patuha (44%) and Bali (30%) and other interests in international 
development stage projects. 

   CalEnergy paid $1,159,215 for the KDG Acquisition and final closing of the 
transaction occurred in January 1998. CalEnergy funded this acquisition with 
available cash and the net proceeds of the equity offering and the debt 
offering completed in October 1997. 

4. ACQUISITIONS 

NORTHERN 

   On December 24, 1996, CE Electric UK plc ("CE Electric"), which in 1997 
was 70% owned indirectly by the Company and 30% owned indirectly by PKS, 
acquired majority ownership of the outstanding ordinary share capital of 
Northern Electric plc ("Northern") pursuant to a tender offer (the "Northern 
Tender Offer") commenced in the United Kingdom on November 5, 1996. As of 
March 18, 1997, CE Electric effectively acquired the remaining ordinary 
shares and owned 100% of Northern's ordinary shares. 

   The Company and PKS contributed to CE Electric approximately $410,000 and 
$176,000 respectively, of the approximately $1,200,000 required to acquire 
all of Northern's ordinary and preference shares in connection with the 
Tender Offer. The Company obtained such funds from cash on hand, short-term 
borrowings, and borrowings of approximately $100,000 under a Credit Agreement 
entered into with Credit Suisse on October 28, 1996 (the "CalEnergy Credit 
Facility"). The Company has repaid the entire CalEnergy Credit Facility 
through the use of proceeds of the Trust Securities offering. The remaining 
funds necessary to consummate the Tender Offer were provided from a pounds 
sterling560,000 Term Loan and Revolving Facility Agreement, dated October 28, 
1996 (the "U.K. Credit Facility"). CE Electric has repaid the entire U.K. 
Credit Facility through the use of proceeds of the senior note and sterling 
bond offerings of CE Electric UK Funding Company.

<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

    The Northern acquisition has been accounted for as a purchase business 
combination. All identifiable assets acquired and liabilities assumed were 
assigned a portion of the cost of acquiring Northern, equal to their fair 
values at the date of the acquisition. Minority interest was recorded at 
historical cost. 

   In 1993, Northern entered into a contract relating to the purchase of 400 
MW of capacity from a 15.4% owned related party, Teesside Power Limited 
("Teesside"), for a period of 15 years beginning April 1, 1993. The contract 
sets escalating purchase prices at predetermined levels. Currently the 
escalating contract prices exceed those paid by the Company to the 
electricity pool (the "Pool") which is operated by the National Grid Group. 
However, under current price cap regulation expected to expire in 1998 the 
Company is able to recover these costs. For the period after the price cap 
regulation ends, the Company has established a liability for the estimated 
loss as a result of this contract. 

   Northern utilizes contracts for differences ("CFDs") to mitigate its 
exposure to volatility in the prices of electricity purchased through the 
Pool. Such contracts allow the Company to effectively convert the majority of 
its anticipated Pool purchases from market to fixed prices. As of December 
31, 1997, CFDs were in place to hedge a portion of electricity purchases of 
approximately 55,000 GWh through the year 2008. 

FALCON SEABOARD 

   On August 7, 1996 the Company completed the acquisition of Falcon Seaboard 
for a cash price of $229,500 including acquisition costs. Through the 
acquisition, the Company indirectly acquired significant ownership interests 
in three operating gas-fired cogeneration facilities and a related 
natural-gas pipeline. The plants are located in Texas, Pennsylvania and New 
York and total 520 MW in capacity. 

   The Falcon Seaboard acquisition has been accounted for as a purchase 
business combination. All identifiable assets acquired and liabilities 
assumed were assigned a portion of the cost of acquiring Falcon Seaboard, 
equal to their fair values at the date of the acquisition. 

EDISON MISSION ENERGY'S PARTNERSHIP INTEREST 

   On April 17, 1996 the Company completed the acquisition of Edison Mission 
Energy's Partnership Interests in four geothermal operating facilities in 
California for a cash purchase price of $71,000 including acquisition costs. 
The four projects, Vulcan, Hoch (Del Ranch), Leathers and Elmore, are located 
in the Imperial Valley of California. Prior to this transaction, the Company 
was a 50% owner of these facilities. 

   The Partnership Interest acquisition has been accounted for as a purchase 
business combination. All identifiable assets acquired and liabilities 
assumed were assigned a portion of the cost of acquiring the Partnership 
Interest, equal to their fair values at the date of the acquisition. 

   Unaudited pro forma combined revenue, income and basic earnings per share 
before extraordinary item of the Company, Northern, Falcon Seaboard, and the 
Partnership Interest for the twelve months ended December 31, 1997 and 1996, 
as if the acquisitions had occurred at the beginning of 1996 after giving 
effect to certain pro forma adjustments related to the acquisitions were 
$2,270,911, $52,430, and $0.78 compared to $2,162,381, $64,811 and $1.18, 
respectively. Excluding the $87,000, $1.29 per share, non-recurring charge, 
pro forma income before extraordinary item would have been $139,430 in 1997.

COSO PROJECT OPERATING FACILITIES 

   The Coso Project operating facilities comprise the Company's proportionate 
share of the assets of three of its Coso Joint Ventures: Coso Finance 
Partners ("Navy I Joint Venture"), Coso Energy Developers ("BLM Joint 
Venture"), and Coso Power Developers ("Navy II Joint Venture"). The Navy I 
power plant is located on land owned by and leased from the U.S. Navy to 
December 2009, with a 10 year extension at the option of the Navy. Under 
terms of the Navy I Joint Venture, current profits and losses are allocated 
46.4% to the Company. The BLM power plant is situated on lands leased from 
the U.S. Bureau of Land Management under a geothermal lease agreement that 
extends until October 31, 2035. The lease may be extended to 2075 at the 
option of the BLM. Under the terms of the BLM Joint Venture agreement, the 
Company's share of profits and losses is 48%. Under terms of the Navy II 
Joint Venture, all profits, losses and capital contributions for Navy II are 
divided equally by the two partners. 

   The amount of royalties paid by Navy I to the U.S. Navy to develop 
geothermal energy for Navy I, Unit 1 on the lands owned by the Navy comprises 
(i) a fee payable during the term of the contract based on the difference 
between the amounts paid by the Navy to Edison for specified quantities of 
electricity and the price as determined under the contract (which currently 
approximates 73% of that paid by the Navy to Edison), and (ii) $25,000 
payable in December 2009, of which the Company's share is $11,600. The 
$25,000 payment is secured by funds placed on deposit monthly, which funds, 
plus accrued interest, will aggregate $25,000. The monthly deposit is 
currently $50. As of December 31, 1997, the balance of funds deposited 
approximated $6,337, which amount is included in restricted cash. 

   Units 2 and 3 of Navy I and the Navy II power plants are on Navy lands, 
for which the Navy receives a royalty based on electric sales revenue at the 
initial rate of 4% escalating to 22% by the end of the contract in December 
2019. The BLM is paid a royalty of 10% of the value of steam produced by the 
geothermal resource supplying the BLM Plant. 

   The Coso Joint Ventures had royalty expense included in operating expenses 
of $13,458, $13,412 and $13,623 in the years ended December 31, 1997, 1996 
and 1995, respectively.

 IMPERIAL VALLEY PROJECT OPERATING FACILITIES 

   The Company currently operates eight geothermal power plants in the 
Imperial Valley in California. The Partnership Project consists of the 
Vulcan, Hoch (Del Ranch), Elmore, and Leathers Partnerships. The remaining 
four plants which comprise the Salton Sea Project are indirect wholly owned 
subsidiaries of the Company. These geothermal power plants consist of Salton 
Sea I, Salton Sea II, Salton Sea III and Salton Sea IV. The Partnership 
Project and the Salton Sea Project are collectively referred to as the 
Imperial Valley Project. The Imperial Valley Project commencement dates and 
nominal capacities are as follows:

Salton Sea IV           May 24, 1996          39.6 MW 
</TABLE>

   The Partnership Project pays royalties based on both energy revenues and 
total electricity revenues. Hoch (Del Ranch) and Leathers pay royalties of 
approximately 5% of energy revenues and 1% of total electricity revenue. 
Elmore pays royalties of approximately 5% of energy revenues. Vulcan pays 
royalties of 4.167% of energy revenues. 

   The Salton Sea Project's weighted average royalty expense in 1997 was 
approximately 6.1%. The royalties are paid to numerous recipients based on 
varying percentages of electrical revenue or steam production multiplied by 
published indices. 

   The Imperial Valley Projects had royalty expense included in operating 
expenses of $14,343, $10,228 and $10,398 in the years ended December 31, 
1997, 1996 and 1995, respectively. 

SIGNIFICANT CUSTOMERS AND CONTRACTS 

   All of the Company's sales of electricity from the Coso Project and 
Imperial Valley Project, which comprise approximately 20% of 1997 operating 
revenue, are to Southern California Edison Company ("Edison") and are under 
long-term power purchase contracts. 

   The Coso Project and the Partnership Project sell all electricity 
generated by the respective plants pursuant to seven long-term SO4 Agreements 
between the projects and Edison. These SO4 Agreements provide for capacity 
payments, capacity bonus payments and energy payments. Edison makes fixed 
annual capacity and capacity bonus payments to the projects to the extent 
that capacity factors exceed certain benchmarks. The price for capacity and 
capacity bonus payments is fixed for the life of the SO4 Agreements. Energy 
is sold at increasing scheduled rates for the first ten years after firm 
operation and thereafter at Edison's Avoided Cost of Energy. 

   The scheduled energy price periods of the Coso Project SO4 Agreements 
extended until at least August 1997 for each of the units operated by the 
Navy I Partnership and extend until at least March 1999 and January 2000 for 
each of the units operated by the BLM and Navy II Partnerships, respectively. 
The Company's share of aggregate annual capacity payments is approximately 
$17,000 and its share of aggregate bonus payments is approximately $3,000.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

    The scheduled energy price periods of the Partnership Project SO4 
Agreements extended until February 1996 for the Vulcan Partnership and extend 
until December 1998, December 1998, and December 1999 for each of the Hoch 
(Del Ranch), Elmore and Leathers Partnerships, respectively. The annual 
capacity payments are approximately $24,500 and the bonus payments are 
approximately $4,400 in aggregate for the four plants. 

   Excluding Navy I and Vulcan, which are receiving Edison's Avoided Cost of 
Energy, the Company's SO4 Agreements provide for energy rates ranging from 
12.8 cents per kWh in 1997 to 15.6 cents per kWh in 1999. The weighted 
average energy rate for all of the Company's SO4 Agreements was 12.0 cents 
per kWh in 1997. 

   Salton Sea I sells electricity to Edison pursuant to a 30-year negotiated 
power purchase agreement, as amended (the "Salton Sea I PPA"), which provides 
for capacity and energy payments. The energy payment is calculated using a 
Base Price which is subject to quarterly adjustments based on a basket of 
indices. The time period weighted average energy payment for Salton Sea I was 
5.3 cents per kWh during 1997. As the Salton Sea I PPA is not an SO4 
Agreement, the energy payments do not revert to Edison's Avoided Cost of 
Energy. The capacity payment is approximately $1,100 per annum. 

   Salton Sea II and Salton Sea III sell electricity to Edison pursuant to 
30-year modified SO4 Agreements that provide for capacity payments, capacity 
bonus payments and energy payments. The price for contract capacity and 
contract capacity bonus payments is fixed for the life of the modified SO4 
Agreements. The energy payments for the first ten year period, which period 
expires in April 2000 and February 1999 are levelized at a time period 
weighted average of 10.6 cents per kWh and 9.8 cents per kWh for Salton Sea 
II and Salton Sea III, respectively. Thereafter, the monthly energy payments 
will be Edison's Avoided Cost of Energy. For Salton Sea II only, Edison is 
entitled to receive, at no cost, 5% of all energy delivered in excess of 80% 
of contract capacity through September 30, 2004. The annual capacity and 
bonus payments for Salton Sea II and Salton Sea III are approximately $3,300 
and $9,700, respectively. 

   The Salton Sea IV Project sells electricity to Edison pursuant to a 
modified SO4 agreement which provides for contract capacity payments on 34 MW 
of capacity at two different rates based on the respective contract 
capacities deemed attributable to the original Salton Sea PPA option (20 MW) 
and to the original Fish Lake PPA (14 MW). The capacity payment price for the 
20 MW portion adjusts quarterly based upon specified indices and the capacity 
payment price for the 14 MW portion is a fixed levelized rate. The energy 
payment (for deliveries up to a rate of 39.6 MW) is at a fixed price for 
55.6% of the total energy delivered by Salton Sea IV and is based on an 
energy payment schedule for 44.4% of the total energy delivered by Salton Sea 
IV. The contract has a 30-year term but Edison is not required to purchase 
the 20 MW of capacity and energy originally attributable to the Salton Sea I 
PPA option after September 30, 2017, the original termination date of the 
Salton Sea I PPA. 

   For the year ended December 31, 1997, and 1996 Edison's average Avoided 
Cost of Energy was 3.3 cents and 2.5 cents, respectively, per kWh which is 
substantially below the contract energy prices earned for the year ended 
December 31, 1997. Estimates of Edison's future Avoided Cost of Energy vary 
substantially from year to year. The Company cannot predict the likely level 
of Avoided Cost of Energy prices under the SO4 Agreements and the modified 
SO4 Agreements at the expiration of the scheduled payment periods. The 
revenues generated by each of the projects operating under SO4 Agreements 
could decline significantly after the expiration of the respective scheduled 
payment periods. 

PHILIPPINE PROJECTS 

   The Upper Mahiao Project was deemed complete in June 1996 and began 
receiving capacity payments pursuant to the Upper Mahiao Energy Conversion 
Agreement ("ECA"), in July of 1996. The project is structured as a ten year 
build-own-operate-transfer project ("BOOT"), in which the Company's 
subsidiary CE Cebu Geothermal Power Company, Inc. ("CE Cebu"), the project 
company, is responsible for providing operations and maintenance during the 
ten year BOOT period. The electricity generated by the Upper Mahiao 
geothermal power plant is sold to PNOC-Energy Development Corporation 

                              F-15           
<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

("PNOC-EDC"), which is also responsible for supplying the facility with the 
geothermal steam. After the ten year cooperation period, and the recovery by 
the Company of its capital investment plus incremental return, the plant will 
be transferred to PNOC-EDC at no cost. 

   PNOC-EDC is obligated to pay for electric capacity that is nominated each 
year by CE Cebu, irrespective of whether PNOC-EDC is willing or able to 
accept delivery of such capacity. PNOC-EDC pays to CE Cebu a fee (the 
"Capacity Fee") based on the plant capacity nominated to PNOC-EDC in any year 
(which, at the plant's design capacity, is approximately 95% of total 
contract revenues) and a fee (the "Energy Fee") based on the electricity 
actually delivered to PNOC-EDC (approximately 5% of total contract revenues). 
Payments under the Upper Mahiao ECA are denominated in U.S. Dollars, or 
computed in U.S. dollars and paid in Philippine pesos at the then-current 
exchange rate, except for the Energy Fee. Significant portions of the 
Capacity Fee and Energy Fee are indexed to U.S. and Philippine inflation 
rates, respectively. PNOC-EDC's payment requirements, and its other 
obligations under the Upper Mahiao ECA are supported by the Government of the 
Philippines through a performance undertaking. 

   Unit I of the Malitbog Project (the "Malitbog Project") was deemed 
complete in July 1996 and Units II and III in July 1997 at which times such 
units commenced receiving capacity payments under the Malitbog ECA. The 
Malitbog Project is owned and operated by Visayas Geothermal Power Company 
("VGPC"), a Philippine general partnership that is wholly owned, indirectly, 
by the Company. Under its contract, VGPC is to sell 100% of its output on 
substantially the same basis as described above for the Upper Mahiao Project 
to PNOC-EDC, which will in turn sell the power to the National Power 
Corporation of the Philippines ("NPC"). However, VGPC receives 100% of its 
revenues from such sales in the form of capacity payments. As with the Upper 
Mahiao Project, the Malitbog Project is structured as a ten year BOOT, in 
which the Company is responsible for providing operations and maintenance for 
the ten year BOOT period. After a ten year cooperation period, and the 
recovery by the Company of its capital investment plus incremental return, 
the plant will be transferred to PNOC-EDC at no cost. 

   The Mahanagdong Project (the "Mahanagdong Project") was deemed complete in 
July 1997 and accordingly, the Mahanagdong Project began receiving capacity 
payments pursuant to the Mahanagdong ECA in August of 1997. The Mahanagdong 
Project is owned and operated by CE Luzon Geothermal Power Company, Inc., a 
Philippine corporation, that is expected to be indirectly owned by the 
Company (after the KDG Acquisition) subject to a minority partner 
participation. The electricity generated by the Mahanagdong Project will be 
sold to PNOC-EDC on a "take or pay" basis, which is also responsible for 
supplying the facility with the geothermal steam. The terms of the 
Mahanagdong ECA are substantially similar to those of the Upper Mahiao ECA. 
All of PNOC-EDC's obligations under the Mahanagdong ECA are supported by the 
Government of the Philippines through a performance undertaking. The capacity 
fees are expected to be approximately 97% of total revenues at the design 
capacity levels and the energy fees are expected to be approximately 3% of 
such total revenues. 

GAS PROJECTS 

   The Saranac Project sells electricity to New York State Electric & Gas 
pursuant to a 15 year negotiated power purchase agreement (the "Saranac 
PPA"), which provides for capacity and energy payments. Capacity payments, 
which in 1997 total 2.2 cents per kWh, are received for electricity produced 
during "peak hours" as defined in the Saranac PPA and escalate at 
approximately 4.1% annually for the remaining term of the contract. Energy 
payments, which average 6.6 cents per kWh in 1997, escalate at approximately 
4.4% annually for the remaining term of the Saranac PPA. The Saranac PPA 
expires in June of 2009. 

   The Power Resources Project sells electricity to Texas Utilities Electric 
Company ("TUEC") pursuant to a 15 year negotiated power purchase agreement 
(the "Power Resources PPA"), which provides for capacity and energy payments. 
Capacity payments and energy payments, which in 1997 are

           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

$3,032 per month and 2.96 cents per kWh, respectively, escalate at 3.5% 
annually for the remaining term of the Power Resources PPA. The Power 
Resources PPA expires in September 2003. 

   The NorCon Project sells electricity to Niagara Mohawk Power Corporation 
("Niagara") pursuant to a 25 year negotiated power purchase agreement (the 
"NorCon PPA") which provides for energy payments calculated pursuant to an 
adjusting formula based on Niagara's ongoing Tariff Avoided Cost and the 
contractual Long-Run Avoided Cost. The NorCon PPA term extends through 
December 2017. The Company and Niagara are currently engaged in discussions 
regarding a potential restructuring or buyout and termination of the NorCon 
PPA. 

   The Yuma Project sells electricity to SDG&E under an existing 30-year 
power purchase contract. The energy is sold at SDG&E's Avoided Cost of Energy 
and the capacity is sold to SDG&E at a fixed price for the life of the power 
purchase contract. The contract term extends through May 2024. 

NEVADA AND UTAH PROPERTIES 

   Roosevelt Hot Springs. The Company operates and owns an approximately 70% 
interest in a geothermal steam field which supplies geothermal steam to a 23 
net MW power plant owned by Utah Power & Light Company ("UP&L") located on 
the Roosevelt Hot Springs property under a 30-year steam sales contract. 

   The Company obtained approximately $20,317 cash under a pre-sale agreement 
with UP&L whereby UP&L paid in advance for the steam produced by the steam 
field. The Company must make certain penalty payments to UP&L if the steam 
produced does not meet certain quantity and quality requirements. 

   Desert Peak. The Company is the owner and operator of a geothermal plant 
at Desert Peak, Nevada that is currently selling electricity to Sierra 
Pacific Power Company ("Sierra") at Sierra's Avoided Cost. Subsequent to year 
end, an indirect subsidiary of the Company entered into a lease agreement 
whereby they will lease the facility to another power producer and receive 
rental payments. 

SALTON SEA MINERALS EXTRACTION 

   The Company developed and owns the rights to a proprietary process 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 is also investigating 
producing silica from the solids precipitated out of the geothermal power 
process. 

TELEPHONE FLAT 

   Under a Bonneville Power Administration ("BPA") geothermal pilot program, 
the Company has been developing a 30 net MW geothermal project which was 
originally located in the Newberry Known Geothermal Resource Area in 
Deschutes County, Oregon (the "Telephone Flat Project"). Pursuant to an 
amended power sales contract the project has been relocated to Telephone Flat 
and BPA has agreed to purchase 30 MW from the project with an option to 
purchase up to an additional 100 MW. The movement of the project to this 
alternative location and BPA's purchase obligation are subject to obtaining a 
final environmental impact statement relating to the new site location. 
Completion of this project is subject to a number of significant 
uncertainties and cannot be assured. 

6. EQUITY INVESTMENTS 

   At December 31, 1997, the Company had an indirect ownership of 
approximately 35% in the Casecnan Project, a combined irrigation and 150 net 
MW hydroelectric power generation project located

   The Company owns all of the common securities of the Trusts. The Trust 
Securities have a liquidation preference of fifty dollars each and represent 
undivided beneficial ownership interests in each of the Trusts. The assets of 
the Trusts consist solely of the Company's Convertible Subordinated 
Debentures due March 10, 2016, February 25, 2012 and September 1, 2027, 
respectively, in outstanding aggregate principal amounts of $103,930, 
$180,000 and $270,000, respectively (collectively, the "Junior Debentures") 
issued pursuant to their respective indentures. The indentures include 
agreements by the Company to pay expenses and obligations incurred by the 
Trusts. Each Trust Security with a par value of $50 is convertible at the 
option of the holder at any time into shares of CalEnergy Common Stock based 
on the conversion rate and subject to customary anti-dilution adjustments. 

   Until converted into the Company's Common Stock, the Trust Securities will 
have no voting rights with respect to the Company and, except under certain 
limited circumstances, will have no voting rights with respect to the Trusts. 
Distributions on the Trust Securities (and Junior Debentures) are cumulative, 
accrue from the date of initial issuance and are payable quarterly in 
arrears. The Junior Debentures are subordinated in right of payment to all 
senior indebtedness of the Company and the Junior Debentures are subject to 
certain covenants, events of default and optional and mandatory redemption 
provisions, all as described in the Junior Debenture indentures. 

   Pursuant to Preferred Securities Guarantee Agreements (collectively, the 
"Guarantees"), between the Company and a preferred guarantee trustee, the 
Company has agreed irrevocably to pay to the holders of the Trust Securities, 
to the extent that the Trustee has funds available to make such payments, 
quarterly distributions, redemption payments and liquidation payments on the 
Trust Securities. Considered together, the undertakings contained in the 
Declarations, Junior Debentures, Indentures and Guarantees constitute full 
and unconditional guarantees by the Company of the Trusts' obligations under 
the Trust Securities. 

11. PREFERRED STOCK 

   On December 1, 1988, the Company distributed a dividend of one preferred 
share purchase right ("right") for each outstanding share of common stock. 
The rights are not exercisable until ten days after a person or group 
acquires or has the right to acquire, beneficial ownership of 20% or more of 
the Company's common stock or announces a tender or exchange offer for 30% or 
more of the Company's common stock. Each right entitles the holder to 
purchase one one-hundredth of a share of Series A junior preferred stock for 
$52. The rights may be redeemed by the Board of Directors up to ten days 
after an event triggering the distribution of certificates for the rights. 
The rights will expire, unless previously redeemed or exercised, on November 
30, 1998. The rights are automatically attached to, and trade with, each 
share of common stock. 

12.  STOCK OPTIONS AND RESTRICTED STOCK 

   The Company has issued various stock options. As of December 31, 1997, a 
total of 6,949 shares are reserved for stock options, of which 6,780 shares 
have been granted and remain outstanding at prices of $3.74 to $40.81 per 
share. 

   The Company has stock option plans under which shares were reserved for 
grant as incentive or non-qualified stock options, as determined by the Board 
of Directors. The plans allow options to be

           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

granted at 85% of their fair market value at the date of grant. Generally, 
options are issued at 100% of fair market value at the date of grant. Options 
granted under the 1996 Plan become exercisable over a period of two to five 
years and expire if not exercised within ten years from the date of grant or, 
in some instances, a lesser term. Prior to the 1996 Plan, the Company granted 
256 options at fair market value at date of grant which had terms of ten 
years and were exercisable at date of grant. In addition, the Company had 
issued approximately 138 options to consultants on terms similar to those 
issued under the 1996 Plan. The non-1996 plan options are primarily options 
granted to Kiewit. 

   The Company granted 500 shares of restricted common stock with an 
aggregate market value of $9,500 in exchange for the relinquishment of 500 
stock options which were canceled by the Company. The shares have all rights 
of a shareholder, subject to certain restrictions on transferability and risk 
of forfeiture. Unearned compensation equivalent to the market value of the 
shares at the date of issuance was charged to stockholders' equity. Such 
unearned compensation was amortized over the vesting period of which 125 
shares were immediately vested and the remaining 375 shares vested through 
January 1, 1998. Accordingly, $5,471, $1,535 and $2,494 of unearned 
compensation was charged to general and administrative expense in 1997, 1996 
and 1995, respectively.

</TABLE>

   The Company applies the intrinsic value based method of accounting for its 
stock-based employee compensation plans. If the fair value based method had 
been applied for 1997, non-cash compensation expense and the effect on net 
income available to common stockholders and earnings per share would have 
been approximately $3,600, or $0.05 per share. If the fair value based method 
had been applied for 1996 and 1995, non-cash compensation expense and the 
effect on net income available to common stockholders and earnings per share 
would have been immaterial. The fair value for stock options was estimated 
using the Black-Scholes option pricing model with assumptions for the 
risk-free interest rate of 5.50% in 1997 and 6.00% in 1996 and 1995, expected 
volatility of 25% in 1997 and 22% in 1996 and 1995, expected life of 
approximately 3.7 years in 1997 and 4.5 years in 1996 and 1995, and no 
expected dividends. The weighted average fair value of options granted during 
1997, 1996 and 1995 was $9.55, $8.62 and $5.72 per option, respectively. 

13. COMMON STOCK SALES & RELATED OPTIONS 

   On October 17, 1997, the Company completed the public offering of 17,100 
shares of its common stock ("Common Stock") at $37 7/8 per share (the "Public 
Offering"). In addition, 2,000 shares of Common Stock were purchased from 
CalEnergy in a direct sale by a trust affiliated with Walter Scott, Jr., the 
Chairman and Chief Executive Officer of PKS (the "Direct Sale"), 
contemporaneously with the closing of the Public Offering. Proceeds from the 
Public Offering and the Direct Sale were approximately $699,920. 

   Simultaneous with the acquisition of the remaining equity interest of 
Magma on February 24, 1995, the Company completed a public offering (the 
"Offering") of 18,170 shares of common stock, which amount included a direct 
sale by the Company to Kiewit of 1,500 shares and the exercise of underwriter 
over-allotment options for 1,500 shares, at a price of $17.00 per share. The 
Company received proceeds of $300,388 from the Offering. 

14. ASSET VALUATION IMPAIRMENT CHARGE 

   The non-recurring charge of $87,000 represents an asset valuation 
impairment charge under Financial Accounting Standard No. 121, "Accounting 
for the Impairment of Long-Lived Assets," relating to CalEnergy's assets in 
Indonesia. Moreover, the Company intends to continue to take actions to 
attempt to require the Government of Indonesia to honor its contractual 
obligations; however, the ultimate outcome of the current uncertain situation 
in Indonesia with respect to the possible abrogation by the Indonesian 
government of the Dieng, Patuha and Bali contracts adds significant risk to 
the completion of those projects. Consequently, the charge of $87,000 
represents the amount by which the carrying amount of such assets exceed the 
fair value of the assets determined by discounting the expected future net 
cash flows of the Indonesia projects, assuming proceeds from political risk 
insurance and no tax benefits.

 15. EXTRAORDINARY ITEM 

   On July 31, 1997, the Finance Act in the United Kingdom was passed by 
Parliament and included the introduction of a one time so-called "windfall 
tax" equal to 23% of the difference between the price paid for Northern upon 
privatization and the Labour government's assessed "value" of Northern as 
calculated by reference to a formula set forth in the July budget. This 
amounted to $135,850, net of minority interest of $58,222, which was recorded 
as an extraordinary item. The first installment was paid December 1, 1997 and 
the second installment is payable on December 1, 1998. 

16. FAIR VALUE OF FINANCIAL INSTRUMENTS 

   The fair value of a financial instrument is the amount at which the 
instrument could be exchanged in a current transaction between willing 
parties, other than in a forced sale or liquidation. Although management uses 
its best judgment in estimating the fair value of these financial 
instruments, there are inherent limitations in any estimation technique. 
Therefore, the fair value estimates presented herein are not necessarily 
indicative of the amounts which the Company could realize in a current 
transaction. 

   The methods and assumptions used to estimate fair value are as follows: 

   Debt instruments -- The fair value of all debt issues listed on exchanges 
has been estimated based on the quoted market prices. 

   Other financial instruments -- All other financial instruments of a 
material nature fall into the definition of short-term and fair value is 
estimated as the carrying amount. 

   The carrying amounts in the table below are included under the indicated 
captions in Notes 7, 8 and 10.

17. INTEREST RATE SWAP AGREEMENTS 

   On December 15, 1997, CE Electric UK Funding Company entered into certain 
interest rate swap agreements for the CE Electric UK Funding Company Senior 
Notes with two large multi-national 

                              F-28

           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

financial institutions. The swap agreements effectively convert the U.S. 
dollar fixed interest rate to a fixed rate in Sterling. For the $125,000 of 
6.853% senior notes, the agreements extend until December 30, 2004 and 
convert the U.S. dollar interest rate to a fixed Sterling rate of 7.744%. For 
the $237,000 of 6.995% senior notes, the agreements extend until December 30, 
2007 and convert the U.S. dollar interest rate to a fixed Sterling rate of 
7.737%. The estimated fair value of these swap agreements is approximately 
$4,929 based on quotes from the counter party to these instruments and 
represents the estimated amount that the Company would expect to pay to 
terminate these agreements. It is the Company's intention to hold the swap 
agreements to their intended maturity. 

18. REGULATORY MATTERS 

   Northern is subject to price cap regulation. Price control formulas for 
the supply and distribution businesses are enforced by the Office of 
Electricity Regulation ("OFFER"). 

   In the distribution business the current price control is expected to last 
until 2000. The formula was reviewed with effect from April 1, 1995 and April 
1, 1996 which resulted in one-time reductions in allowed income per unit 
distributed of about 17% and 13% respectively, with continuing real 
reductions in each of the subsequent three years 1997/98 to 1999/2000. The 
current formula requires that each year regulated distribution income per 
unit is increased or decreased by RPI-Xd where RPI reflects the average of 
the twelve month inflation rates recorded for the previous July to December 
period and Xd is set at 3%. The formula also takes account of the changes in 
system electrical losses, the number of customers connected and the voltage 
at which customers receive the units of electricity distributed. 

   In the supply business the current formula applies only to customers with 
demands below 100kW. Under the current formula the purchase cost of 
electricity and the cost of transmission, distribution and the fossil fuel 
levy are passed through to customers in full. That part of the formula 
governing Northern's own supply business costs requires that this element of 
the permitted income falls by 2% per annum in real terms. The current formula 
is due to be replaced from April 1, 1998 with a new formula which will 
require Northern to reduce prices to those customers protected by the new 
price control from the level prevailing at August 1, 1997 by about 4.2% 
(minus inflation) with effect from April 1, 1998 and a further 3% (minus 
inflation) with effect from April 1, 1999. 

   The market for electricity supplied to customers with demands over 1MW was 
opened to competition in 1990. In 1994 this limit was reduced to 0.1MW. In 
1998, liberalization of the entire market is due to commence in stages with 
complete liberalization achieved by June 1999. 

19. PENSION COMMITMENTS 

   Northern participates in the Electricity Supply Pension Scheme, which 
provides pension and other related defined benefits, based on final 
pensionable pay, to substantially all employees throughout the Electricity 
Supply Industry in the United Kingdom. 

   The actuarial computation for December 31, 1997 and 1996 assumed interest 
rates of 6.75% and 7.75%, respectively, an expected return on plan assets of 
7.25% and 8.25%, respectively, and annual compensation increases of 4.75% and 
5.75%, respectively, over the remaining service lives of employees covered 
under the plan. Amounts funded to the pension are primarily invested in 
equity and fixed income securities. Northern's funding policy for the plan is 
to contribute annually at a rate that is intended to remain a level 
percentage of compensation for the covered employees.

20. COMMITMENTS AND CONTINGENCIES 

CASECNAN 

   In November 1995, the Company closed the financing and commenced 
construction of 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 Water and Energy Company, Inc., a Philippine Corporation ("CE 
Casecnan") which is expected to be approximately 70% indirectly owned by the 
Company (after the KDG Acquisition), is developing the Casecnan Project. CE 
Casecnan financed a portion of the costs of the Casecnan Project through the 
issuance of $125,000 of its 11.45% Senior Secured Series A Notes due 2005 and 
$171,500 of its 11.95% Senior Secured Series B Bonds due 2010 and $75,000 of 
its Secured Floating Rate Notes due 2002, pursuant to an indenture dated as 
of November 27, 1995, as amended to date. 

   The Casecnan Project was being constructed pursuant to a fixed-price, 
date-certain, turnkey construction contract (the "Hanbo Contract") on a joint 
and several basis by Hanbo Corporation ("Hanbo") and Hanbo Engineering and 
Construction Co., Ltd. ("HECC"), both of which are South Korean corporations. 
As of May 7, 1997, CE Casecnan terminated the Hanbo Contract due to defaults 
by Hanbo and HECC including the insolvency of each such company. On May 7, 
1997 CE Casecnan entered into a new turnkey engineering, procurement and 
construction contract to complete the construction of the Casecnan Project 
(the "Replacement Contract"). The work under the Replacement Contract is 
being conducted by a consortium consisting of Cooperativa Muratori Cementisti 
CMC di Ravenna and Impressa Pizzarottie & C. Spa working together with 
Siemens A.G., Sulzer Hydro Ltd., Black & Veatch and Colenco Power Engineering 
Ltd. (collectively, the "Replacement Contractor").

<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

    In connection with the Hanbo Contract termination, CE Casecnan tendered a 
certificate of drawing to Korea First Bank ("KFB") on May 7, 1997 under the 
irrevocable standby letter of credit issued by KFB as security under the 
Hanbo Contract to pay for certain transition costs and other presently 
ascertainable damages under the Hanbo Contract. As a result of KFB's wrongful 
dishonor of the draw request, CE Casecnan filed an action in New York State 
Court. That Court granted CE Casecnan's request for a temporary restraining 
order requiring KFB to deposit $79,329, the amount of the requested draw, in 
an interest bearing account with an independent financial institution in the 
United States. KFB appealed this order, but the appellate court denied KFB's 
appeal and on May 19, 1997, KFB transferred funds in the amount of $79,329 to 
a segregated New York bank account pursuant to the Court order. If KFB were 
to fail to honor its obligations under the Casecnan letter of credit, such 
action could have a material adverse effect on the Casecnan Project and CE 
Casecnan. 

   On August 6, 1997, CE Casecnan announced that it had issued a notice to 
proceed to the Replacement Contractor. The Replacement Contractor was already 
on site and has fully mobilized and commenced engineering, procurement and 
construction work on the Casecnan Project. 

   On August 27, 1997, CE Casecnan announced that it had received a favorable 
summary judgment ruling in New York State Court against KFB. The judgment, 
which has been appealed by the bank, requires KFB to honor the $79,329 
drawing by CE Casecnan on the $117,850 irrevocable standby letter of credit. 

   On September 29, 1997, CE Casecnan tendered a second certificate of 
drawing for $10,828 to KFB and on December 30, 1997, CE Casecnan tendered a 
third certificate of drawing for $2,920 to KFB. KFB also wrongfully 
dishonored these draws, but pursuant to a stipulation agreed to deposit the 
draw amounts in an interest bearing account with the same independent 
financial institution in the United States pending resolution of the appeal 
regarding the first draw and agreed to expedite the appeal. 

   The receipt of the letter of credit funds from KFB remains essential and 
CE Casecnan will continue to press KFB to honor its clear obligations under 
the letter of credit and to pursue Hanbo and KFB for any additional damages 
arising out of their actions to date. If KFB were to fail to honor its 
obligations under the Casecnan letter of credit, such action could have a 
material adverse effect on the Casecnan Project and CE Casecnan. 

   On September 2, 1997, Hanbo and HECC filed a Request for Arbitration 
before the International Chamber of Commerce ("ICC"). The Request for 
Arbitration asserts various claims by Hanbo and HECC against CE Casecnan 
relating to the terminated Hanbo Contract and seeking damages. On October 10, 
1997, CE Casecnan served its answer and defenses in response to the Request 
for Arbitration as well as counterclaims against Hanbo and HECC for breaches 
of the Hanbo Contract. The arbitration proceedings before the ICC are ongoing 
and CE Casecnan intends to pursue vigorously its claims against Hanbo, HECC 
and KFB in the proceedings described above. 

INDONESIA 

   On September 20, 1997, a Presidential Decree (the "Decree") was issued in 
Indonesia, providing for government action to the effect that, in order to 
address certain recent fluctuations in the value of the Indonesian currency, 
the start-up dates for a number of private power projects would be: (i) 
continued according to their initial schedule (because construction was 
underway); (ii) postponed as to their start-up dates (because they are not 
yet in construction) until economic conditions have recovered; or (iii) 
reviewed with a view to being continued, postponed or rescheduled, depending 
on the status of those projects. In the Decree, Dieng Units 1, 2 and 3 are 
approved to continue according to their initial schedule; Patuha Unit 1 and 
Bali Units 1 and 2 are to receive further review to determine whether or not 
they should be continued in accordance with their initial schedule; and Bali 
Units 3 and 4, Patuha Units 2, 3 and 4 and Dieng Unit 4 are to be postponed 
for an unspecified period. In this regard, the Company notes that its 
contracts and government undertakings for the Dieng, Patuha and Bali projects 
do not by

their terms permit such categorization or delays by the government and that 
the Company has obtained political risk insurance coverage for its Dieng and 
Patuha projects. Moreover, the Company intends to continue to take actions to 
attempt to require the Government of Indonesia to honor its contractual 
obligations; however, subsequent actions by the Government of Indonesia and 
continued economic problems in Indonesia have created further uncertainty as 
to whether the contracts for such projects will be abrogated by the 
Indonesian government and accordingly have created significant risks to the 
completion of these projects. As a result, the Company recorded a SFAS 121 
asset valuation impairment charge of $87,000 in the fourth quarter of 1997. 
This charge includes all reasonably estimated asset valuation impairments 
associated with the Company's assets in Indonesia and gives effect to the 
political risk insurance on such investments. 

EDISON 

   On June 9, 1997, Edison filed a complaint alleging breach of the power 
purchase agreements ("SO4 Agreements") between Edison and the Coso Joint 
Ventures as a result of alleged improper venting of certain noncondensible 
gases at the Coso geothermal energy project. In the complaint Edison seeks 
unspecified damages, including the refund of certain amounts previously paid 
under the SO4 Agreements, and termination of the SO4 Agreements. In September 
1997, the Coso Joint Ventures and the Company filed a cross-complaint against 
Edison and its affiliates, The Mission Group and Mission Power Engineering 
Company alleging, among other things, that Edison's lawsuit violates the 1993 
settlement agreement which settled certain litigation arising from the 
construction of certain units at the Coso geothermal project by Edison 
affiliates. In addition, the Coso Joint Ventures filed a separate complaint 
against Edison alleging breach of the SO4 Agreements, unfair business 
practices, slander and various other tort and contract claims. The actions 
were effectively consolidated in December 1997. As a result of certain 
procedural actions by the parties and a November court order, Edison filed an 
amended complaint on December 16, 1997 and the Coso Joint Ventures amended 
their cross-complaint. The litigation is in its early procedural stages and 
the pleadings have not been settled. The Coso Joint Ventures believe that 
their claims and defenses are meritorious and that they will prevail if the 
matter is ultimately heard on its merits. The Coso Joint Ventures intend to 
vigorously defend this action and prosecute all available counterclaims 
against Edison. 

NYSEG 

   On February 14, 1995, NYSEG filed with the 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 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.

<PAGE>
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
           FOR THE THREE YEARS ENDED DECEMBER 31, 1997 (Continued) 

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

LEASES 

   Certain retail facilities, buildings and equipment are leased. The leases 
expire in periods ranging from one to 75 years and some provide for renewal 
options. 

   At December 31, 1997, the Company's future minimum rental payments with 
respect to non-cancelable operating leases were as follows:

Board of Directors and Stockholders 
CalEnergy Company, Inc. 
Omaha, Nebraska 

   We have reviewed the accompanying consolidated balance sheet of CalEnergy 
Company, Inc. and subsidiaries as of June 30, 1998, and the related 
consolidated statements of operations for the three and six month periods 
ended June 30, 1998 and 1997 and the related consolidated statements of cash 
flows for the six month periods ended June 30, 1998 and 1997. 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 CalEnergy Company, Inc. and 
subsidiaries as of December 31, 1997, 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 February 12, 1998, 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, 1997 is fairly stated, in all material 
respects, in relation to the consolidated balance sheet from which it has 
been derived.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
             (IN THOUSANDS, EXCEPT PER SHARE AND PER KWH AMOUNTS) 

1. GENERAL: 

   In the opinion of management of CalEnergy Company, Inc. (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 June 30, 1998 and the results of 
operations for the three and six months ended June 30, 1998 and 1997, and 
cash flows for the six months ended June 30, 1998 and 1997. The results of 
operations for the three and six months ended June 30, 1998 and 1997 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, and its proportionate share 
of the partnerships and joint ventures in which it has an undivided interest 
in the assets and is proportionally liable for its share of liabilities. 
Other investments and corporate joint ventures 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 1997 financial statements and supporting footnote 
disclosures have been reclassified to conform to the 1998 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. SUBSEQUENT EVENT: 

   On August 12, 1998, the Company announced that it had entered into an 
Agreement and Plan of Merger with MidAmerican Energy Holdings Company 
("MidAmerican"), pursuant to which the Company agreed (i) to pay $27.15 in 
cash for each outstanding share of MidAmerican common stock (valuing 
MidAmerican at approximately $4 billion, including $1.4 billion of debt and 
preferred stock which will remain outstanding at MidAmerican) in a merger, 
pursuant to which MidAmerican will become a wholly owned subsidiary of the 
Company, and (ii) to reincorporate in the state of Iowa and be renamed 
MidAmerican Energy Holdings Company. Closing of the transaction is subject to 
the approval of the shareholders of both companies and the obtaining of 
certain regulatory approvals.

4. KDG ACQUISITION: 

   On September 11, 1997, the Company signed a definitive agreement with 
Kiewit Diversified Group ("KDG"), a wholly owned subsidiary of Peter Kiewit 
Sons', Inc. ("PKS"), for the Company to purchase KDG's ownership interest in 
various project partnerships and CalEnergy common shares (the "KDG 
Acquisition"). 

   KDG's ownership interest in CalEnergy comprised approximately 20,231 
shares of common stock (assuming exercise by KDG of one million options to 
purchase CalEnergy shares), the 30% interest in Northern Electric, as well as 
the following minority project interests: Mahanagdong (45%), Casecnan (35%), 
Dieng (47%), Patuha (44%) and Bali (30%) and other interests in international 
development stage projects. 

   CalEnergy paid $1,159,215 for the KDG Acquisition and final closing of the 
transaction occurred in January 1998. CalEnergy funded this acquisition with 
available cash and the net proceeds of the equity offering and the debt 
offering completed in October 1997. The KDG Acquisition is being accounted 
for under the purchase method of accounting. The purchase price has been 
allocated to assets acquired and liabilities assumed based on preliminary 
valuations and the Company is awaiting final valuations. The assets acquired 
will be amortized over their estimated useful life and goodwill over a period 
of ten to forty years. 

   Pro forma revenue and net income, as if the acquisition occurred at the 
beginning of the period presented, was not materially different from 
historical amounts.

 5. CONVERSION OF PHILIPPINE TERM LOANS: 

   On April 8, 1998, the Company converted the construction project financing 
for its Malitbog geothermal power project to term loans of $170,726. The 
Overseas Private Investment Corporation ("OPIC") is providing term loan 
financing of $60,904 that was fixed as of June 15, 1998 at an interest rate 
of 9.176%, maturing in 2005. A syndicate of international commercial banks is 
providing the remaining $109,822 of term loan financing at a variable 
interest rate based on LIBOR, maturing in 2005. 

   On May 5, 1998, the Company converted the construction project financing 
for its Upper Mahiao geothermal power project to term loans of $155,517. 
Export-Import Bank of the United States ("Ex-Im Bank") is providing term loan 
financing of $145,517 at a fixed interest rate of 5.95%, maturing in 2006. 
United Coconut Planters Bank of the Philippines is providing the remaining 
$10,000 of term loan financing at a variable interest rate based on LIBOR, 
maturing in 2003. 

   On June 18, 1998, the Company converted the construction project financing 
for its Mahanagdong geothermal power project to term loans of $220,378. Ex-Im 
Bank is providing term loan financing of $180,378 at a fixed interest rate of 
6.92%, maturing in 2007. OPIC is providing the remaining $40,000 of term loan 
financing at a variable interest rate based on LIBOR, maturing in 2007. 

6. COMMITMENTS AND CONTINGENCIES: 

 CASECNAN 

   On April 17, 1998, CE Casecnan Water and Energy Company, Inc., a 
Philippine Corporation ("CE Casecnan") which is currently approximately 70% 
indirectly owned by the Company, announced that it and Hanbo Corporation, 
Hanbo Engineering and Construction Co., Ltd., Hanbo Steel Company, Ltd. and 
Korea First Bank ("KFB") had reached a settlement with regard to certain 
disputed terminated contracts and standby letter of credit issues. Under the 
settlement, KFB agreed to pay CE Casecnan $90,000 and the parties have 
discontinued with prejudice the pending arbitration and litigation 
proceedings and released each other from all claims arising out of the 
litigation and arbitration. In accordance with the terms of such settlement, 
CE Casecnan received $10,000 from KFB on April 17, 1998 and the remaining 
$80,000, including interest, on July 3, 1998. 

 INDONESIA 

   On September 20, 1997, a Presidential Decree (the "Decree") was issued in 
Indonesia, providing for government action to the effect that, in order to 
address certain recent fluctuations in the value of the Indonesian currency, 
the start-up dates for a number of private power projects would be: (i) 
continued according to their initial schedule (because construction was 
underway); (ii) postponed as to their start-up dates (because they were not 
yet under construction) until economic conditions recover; or (iii) reviewed 
with a view to being continued, postponed or rescheduled, depending on the 
status of those projects. In the Decree, Dieng Units 1, 2 and 3 were approved 
to continue according to their initial schedule; Patuha Unit 1 and Bali Units 
1 and 2 were to receive further review to determine whether or not they would 
be continued in accordance with their initial schedule; and Bali Units 3 and 
4, Patuha Units 2, 3 and 4 and Dieng Unit 4 were postponed for an unspecified 
period. In this regard, the Company notes that its contracts and government 
undertakings for the Dieng, Patuha and Bali projects do not by their terms 
permit such categorization or delays by the government and that the Company 
has obtained political risk insurance coverage for its Dieng and Patuha 
projects. 

   Moreover, the Company intends to continue to take actions to attempt to 
require the Government of Indonesia to honor its contractual obligations; 
however, subsequent actions by the Government of Indonesia and continued 
economic problems in Indonesia have created further uncertainty as to whether 
the contracts for such projects will be abrogated by the Indonesian 
government and accordingly have created significant risks to the completion 
of these projects.

6. COMMITMENTS AND CONTINGENCIES:  (Continued) 
    The Company believes it has fully reserved for the Indonesian exposure as 
part of the $87,000 1997 fourth quarter asset valuation impairment charge. 

 EDISON 

   On June 9, 1997, Edison filed a complaint alleging breach of the power 
purchase agreements ("SO4 Agreements") between Edison and Coso Finance 
Partners, Coso Power Partners and Coso Energy Developers as a result of 
alleged improper venting of certain noncondensible gases at the Coso 
geothermal energy project located in California (partnerships in which 
CalEnergy holds an approximate 50% ownership interest, collectively the "Coso 
Partnerships"). 

   In the complaint Edison seeks unspecified damages, including the refund of 
certain amounts previously paid under the SO4 Agreements, and termination of 
the SO4 Agreements. In September 1997, the Coso Partnerships and the Company 
filed a cross-complaint against Edison and its affiliates, The Mission Group 
and Mission Power Engineering Company alleging, among other things, that 
Edison's lawsuit violates the 1993 settlement agreement which settled certain 
litigation arising from the construction of certain units at the Coso 
geothermal project by Edison affiliates. In addition, the Coso Partnerships 
filed a separate complaint against Edison alleging breach of the SO4 
Agreements, unfair business practices, slander and various other tort and 
contract claims. The actions were effectively consolidated in December 1997. 
As a result of certain procedural actions by the parties and a November court 
order, Edison filed an amended complaint on December 16, 1997 and the Coso 
Partnerships amended their cross-complaint. In addition, the Court has struck 
Edison's request to terminate the SO4 Agreements and obtain a refund of all 
funds paid to the Coso Partnerships. The litigation is in its early 
procedural stages and the pleadings have not been settled. The Coso 
Partnerships believe that their claims and defenses are meritorious and that 
they will prevail if the matter is ultimately heard on its merits. The Coso 
Partnerships intend to vigorously defend this action and prosecute all 
available counterclaims against Edison. 

 NYSEG 

   On February 14, 1995, NYSEG filed with the 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 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 (a partnership in which CalEnergy holds an 
approximate 45% economic interest) 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.

6. COMMITMENTS AND CONTINGENCIES:  (Continued) 
    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 from the Saranac Partnership. 
Saranac and other parties have filed motions to dismiss and oral arguments on 
those motions were heard on March 2, 1998. Saranac believes that NYSEG's 
claims are without merit for the same reasons described in the FERC's orders. 

7. COMPREHENSIVE INCOME: 

   In June 1997, the Financial Accounting Standards Board ("FASB") issued 
Statements of Financial Accounting Standards ("SFAS") No. 130, "Reporting 
Comprehensive Income", which established standards for reporting and display 
of comprehensive income and its components. Comprehensive income for the 
three months ended June 30, 1998 and 1997 was $29,948 and $36,209, 
respectively. Comprehensive income for the six months ended June 30, 1998 and 
1997 was $68,090 and $31,632, respectively. Comprehensive income differs from 
net income due to foreign currency translation adjustments. 

8. ACCOUNTING PRONOUNCEMENTS: 

   In March 1998, the Accounting Standards Executive Committee ("AcSEC") 
issued Statement of Position ("SOP") No. 98-1, "Accounting for the Costs of 
Computer Software Developed or Obtained for Internal Use." The SOP is 
effective for financial statements for fiscal years beginning after December 
15, 1998. The Company has not yet determined the impact of this accounting 
pronouncement. 

   In April 1998, the AcSEC issued SOP No. 98-5, "Reporting on the Costs of 
Start-Up Activities", which requires that costs of start-up activities and 
organization costs be expensed as incurred. The SOP is effective for 
financial statements for fiscal years beginning after December 15, 1998. The 
Company has not yet determined the impact of this accounting pronouncement. 

   In June 1998, the FASB issued 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 is effective for all fiscal 
quarters of fiscal years beginning after June 15, 1999. The Company has not 
yet determined the impact of this accounting pronouncement.

To the Shareholders and Board
of Directors of MidAmerican
Energy Holdings Company and 
Subsidiaries:

                       REPORT OF INDEPENDENT ACCOUNTANTS 

   We have audited the accompanying consolidated balance sheets and 
statements of capitalization of MidAmerican Energy Holdings Company and 
subsidiaries as of December 31, 1997 and 1996, and the related consolidated 
statements of income, retained earnings and cash flows for each of the three 
years in the period ended December 31, 1997. These financial statements are 
the responsibility of the Company's management. Our responsibility is to 
express an opinion on these financial statements based on our audits. 

   We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall

                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 

(A) MERGER AND FORMATION OF THE COMPANY: 

   MidAmerican Energy Holdings Company (Company or Holdings) is a holding 
company for MidAmerican Energy Company (MidAmerican), MidAmerican Capital 
Company (MidAmerican Capital) and Midwest Capital Group, Inc. (Midwest 
Capital). Prior to December 1, 1996, MidAmerican held the capital stock of 
MidAmerican Capital and Midwest Capital. Effective December 1, 1996, each 
share of MidAmerican common stock was exchanged for one share of Holdings 
common stock. As part of the transaction, MidAmerican distributed the capital 
stock of MidAmerican Capital and Midwest Capital to Holdings. 

   MidAmerican was formed on July 1, 1995, as a result of the merger of 
Iowa-Illinois Gas and Electric Company (Iowa-Illinois), Midwest Resources 
Inc. (Midwest Resources) and its utility subsidiary, Midwest Power Systems 
Inc. (Midwest Power). Each outstanding share of preferred and preference 
stock of the predecessor companies was converted into one share of a 
similarly designated series of MidAmerican preferred stock, no par value. 
Each outstanding share of common stock of Midwest Resources and Iowa-Illinois 
was converted into one share and 1.47 shares, respectively, of MidAmerican 
common stock, no par value. The merger was accounted for as a 
pooling-of-interest and the financial statements included herein are 
presented as if the merger and the formation of the holding company had 
occurred as of the earliest period shown. 

(B) CONSOLIDATION POLICY AND PREPARATION OF FINANCIAL STATEMENTS: 

   The accompanying Consolidated Financial Statements include the Company and 
its wholly owned subsidiaries, MidAmerican, MidAmerican Capital and Midwest 
Capital. All significant intercompany transactions have been eliminated. 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent liabilities at the date of the financial statements 
and the reported amounts of revenues and expenses during the reporting 
period. Actual results may differ from those estimates. 

(C) REGULATION: 

   MidAmerican's utility operations are subject to the regulation of the Iowa 
Utilities Board (IUB), the Illinois Commerce Commission (ICC), the South 
Dakota Public Utilities Commission, and the Federal Energy Regulatory 
Commission (FERC). MidAmerican's accounting policies and the accompanying 
Consolidated Financial Statements conform to generally accepted accounting 
principles applicable to rate-regulated enterprises and reflect the effects 
of the ratemaking process. 

   Statement of Financial Accounting Standards (SFAS) No. 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 possible consequence of the changes in the utility industry is the 
discontinued applicability of SFAS 71. The majority of MidAmerican's electric 
and gas utility operations currently meet the criteria of SFAS 71, but its 
applicability is periodically reexamined. On December 16, 1997, MidAmerican's 
generation operations serving Illinois were no longer subject to the 
provisions of SFAS 71 due to passage of restructuring legislation in 
Illinois. Thus, MidAmerican was required to write off regulatory assets and 
liabilities from its balance sheet related to its Illinois generation 
operations. The net amount of such write-off's were immaterial. If other 
utility operations no longer meet the criteria of SFAS 71, MidAmerican would 
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. The following regulatory assets, primarily included in Other Assets 
in the Consolidated Balance Sheets, represent probable future revenue to 
MidAmerican because these costs are expected to be recovered in charges to 
utility customers (in thousands):

(D) REVENUE RECOGNITION: 

   Revenues are recorded as services are rendered to customers. MidAmerican 
records unbilled revenues, and related energy costs, representing the 
estimated amount customers will be billed for services rendered between the 
meter-reading dates in a particular month and the end of such month. Accrued 
unbilled revenues were $80.2 million and $70.1 million at December 31, 1997 
and 1996, respectively, and are included in Receivables on the Consolidated 
Balance Sheets. 

   MidAmerican's Illinois and South Dakota jurisdictional sales, or 
approximately 11% of total retail electric sales, and the majority of its 
total retail gas sales are subject to adjustment clauses. These clauses allow 
MidAmerican to adjust the amounts charged for electric and gas service as the 
costs of gas, fuel for generation or purchased power change. The costs 
recovered in revenues through use of the adjustment clauses are charged to 
expense in the same period. 

(E) DEPRECIATION AND AMORTIZATION: 

   MidAmerican's provisions for depreciation and amortization for its utility 
operations are based on straight-line composite rates. The average 
depreciation and amortization rates for the years ended December 31 were as 
follows: 

<TABLE>
<CAPTION>

Gas ........   3.4%   3.7%    3.7% 
</TABLE>

   Utility plant is stated at original cost which includes overhead costs, 
administrative costs and an allowance for funds used during construction. 

   The cost of repairs and minor replacements is charged to maintenance 
expense. Property additions and major property replacements are charged to 
plant accounts. The cost of depreciable units of utility plant retired or 
disposed of in the normal course of business is eliminated from the utility 
plant accounts and such cost, plus net removal cost, is charged to 
accumulated depreciation. 

   An allowance for the estimated annual decommissioning costs of the Quad 
Cities Nuclear Power Station (Quad Cities) equal to the level of funding is 
included in depreciation expense. See Note 4(e) for additional information 
regarding decommissioning costs.

</TABLE>

   Marketable securities generally consist of preferred stocks, common stocks 
and mutual funds held by MidAmerican Capital. Investments in marketable 
securities classified as available-for-sale are reported at fair value with 
net unrealized gains and losses reported as a net of tax amount in Common 
Shareholders' Equity until realized. Investments in marketable securities 
that are classified as held-to-maturity are reported at amortized cost. An 
other-than-temporary decline in the value of a marketable security is 
recognized through a write-down of the investment to earnings. 

   Investments held by the nuclear decommissioning trust fund for the Quad 
Cities units are classified as available-for-sale and are reported at fair 
value with net unrealized gains and losses reported as adjustments to the 
accumulated provision for nuclear decommissioning. 

(G) CONSOLIDATED STATEMENTS OF CASH FLOWS: 

   The Company considers all cash and highly liquid debt instruments 
purchased with a remaining maturity of three months or less to be cash and 
cash equivalents for purposes of the Consolidated Statements of Cash Flows.

(H) ACCOUNTING FOR LONG-TERM POWER PURCHASE CONTRACT: 

   Under a long-term power purchase contract with Nebraska Public Power 
District (NPPD), expiring in 2004, MidAmerican purchases one-half of the 
output of the 778-megawatt Cooper Nuclear Station (Cooper). The Consolidated 
Balance Sheets include a liability for MidAmerican's fixed obligation to pay 
50% of NPPD's Nuclear Facility Revenue Bonds and other fixed liabilities. A 
like amount representing MidAmerican's right to purchase power is shown as an 
asset. 

   Capital improvement costs prior to July 11, 1997, including carrying 
costs, were deferred, and are being amortized and recovered in rates over 
either a five-year period or the term of the NPPD contract. Beginning July 
11, 1997, capital improvement costs are recovered currently from customers 
and are expensed as incurred. 

   The fuel cost portion of the power purchase contract is included in Cost 
of Fuel, Energy and Capacity on the Consolidated Statements of Income. All 
other costs MidAmerican incurs in relation to its long-term power purchase 
contract with NPPD are included in Other Operating Expenses on the 
Consolidated Statements of Income. 

   See Notes 4(d), 4(e) and 4(f) for additional information regarding the 
power purchase contract. 

(I) ACCOUNTING FOR DERIVATIVES: 

   1) Preferred Stock Hedge Instruments: 

   The Company is exposed to market value risk from changes in interest rates 
for certain fixed rate sinking fund preferred and perpetual preferred stocks 
(fixed rate preferred stocks) included in Investments on the Consolidated 
Balance Sheets. The Company reviews the interest rate sensitivity of these 
securities and purchases put options on U.S. Treasury securities (put 
options) to reduce interest rate risk on preferred stocks. The Company does 
not purchase or sell put options for speculative purposes. The Company's 
intent is to substantially offset any change in market value of the fixed 
rate preferred stocks due to a change in interest rates with a change in 
market value of the put options. 

   The preferred stocks are publicly traded securities and, as such, changes 
in their fair value are reported, net of income taxes, as a valuation 
allowance in shareholders' equity. Unrealized gains and losses on the 
associated put options are included in the determination of the fair value of 
the preferred stocks. The fair value of the put options, including unrealized 
gains and losses, included in the determination of the fair value of the 
preferred securities as of December 31, 1997 and 1996 was $1.9 million and 
$5.1 million, respectively. Realized gains and losses on the put options are 
included in Realized Gains and Losses on Securities, Net in the Consolidated 
Statements Income in the period the underlying hedged fixed rate preferred 
stocks are sold. At December 31, 1997, the Company held put options with a 
notional value of $3.2 million. 

   2) Gas Futures Contracts and Swaps: 

   The Company uses gas futures contracts and swap contracts to reduce its 
exposure to changes in the price of natural gas purchased to meet the needs 
of its customers and to manage margins on natural gas storage opportunities. 
Investments in natural gas futures contracts, which total $1.6 million and 
$0.8 million as of December 31, 1997 and 1996, are included in Receivables on 
the Consolidated Balance Sheets. Gains and losses on gas futures contracts 
that qualify for hedge accounting are deferred and reflected as adjustments 
to the carrying value of the hedged item or included in Other Assets on the 
Consolidated Balance Sheets until the underlying physical transaction is 
recorded if the instrument is used to hedge an anticipated future 
transaction. The net gain or loss on gas futures contracts is included in the 
determination of income in the same period as the expense for the physical 
delivery of the natural gas. 

                              F-55           
<PAGE>
                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

Realized gains and losses on gas futures contracts and the net amounts 
exchanged or accrued under the natural gas swap contracts are included in 
Cost of Gas Sold, Other Net or Nonregulated-Costs of Sales consistent with 
the expense for the physical commodity. Deferred net gains (losses) related 
to the Company's gas futures contracts are $(0.4) million and $0.8 million as 
of December 31, 1997 and 1996, respectively. 

   The Company periodically evaluates the effectiveness of its natural gas 
hedging programs. If a high degree of correlation between prices for the 
hedging instruments and prices for the physical delivery is not achieved, the 
contracts are recorded at fair value and the gains or losses are included in 
the determination of income. At December 31, 1997 the Company held the 
following hedging instruments:

</TABLE>

(2) LONG-TERM DEBT: 

   The Company's sinking fund requirements and maturities of long-term debt 
for 1998 through 2002 are $145 million, $106 million, $134 million, $125 
million and $25 million, respectively. 

   The interest rate on the Company's Adjustable Rate Series Mortgage Bonds 
is reset every two years at 160 basis points over the average yield to 
maturity of 10-year Treasury securities. The rate was reset in 1997. 

   The Company's Variable Rate Pollution Control Revenue Obligations bear 
interest at rates that are periodically established through remarketing of 
the bonds in the short-term tax-exempt market. The Company, at its option, 
may change the mode of interest calculation for these bonds by selecting from 
among several alternative floating or fixed rate modes. The interest rates 
shown in the Consolidated Statements of Capitalization are the weighted 
average interest rates as of December 31, 1997 and 1996. The Company 
maintains dedicated revolving credit facility agreements or renewable lines 
of credit to provide liquidity for holders of these issues. 

   Substantially all the former Iowa-Illinois utility property and 
franchises, and substantially all of the former Midwest Power electric 
utility property in Iowa, or approximately 82% of gross utility plant, is 
pledged to secure mortgage bonds. 

   MidAmerican Capital has $64 million and $50 million unsecured revolving 
credit facility agreements which mature in 1998. Borrowings under these 
agreements may be on a fixed rate, floating rate or competitive bid rate 
basis. All subsidiary long-term borrowings outstanding at December 31, 1997, 
are without recourse to Holdings.

(3) JOINTLY OWNED UTILITY PLANT: 

   Under joint plant ownership agreements with other utilities, MidAmerican 
had undivided interests at December 31, 1997, in jointly owned generating 
plants as shown in the table below. 

   The dollar amounts below represent MidAmerican's share in each jointly 
owned unit. Each participant has provided financing for its share of each 
unit. Operating Expenses on the Consolidated Statements of Income include 
MidAmerican's share of the expenses of these units (dollars in millions).

(4) COMMITMENTS AND CONTINGENCIES: 

(A) CAPITAL EXPENDITURES: 

   Utility construction expenditures for 1998 are estimated to be $201 
million, including $13 million for Quad Cities nuclear fuel. Nonregulated 
capital expenditures depend upon the availability of investment opportunities 
and other factors. During 1998, such expenditures are estimated to be 
approximately $10 million. 

(B) MANUFACTURED GAS PLANT FACILITIES: 

   The United States Environmental Protection Agency (EPA) and the state 
environmental agencies have determined that contaminated wastes remaining at 
certain decommissioned manufactured gas plant facilities may pose a threat to 
the public health or the environment if such contaminants are in sufficient 
quantities and at such concentrations as to warrant remedial action. 

   MidAmerican is evaluating 26 properties which were, at one time, sites of 
gas manufacturing plants in which it may be a potentially responsible party 
(PRP). The purpose of these evaluations is to determine whether waste 
materials are present, whether such materials constitute an environmental or 
health risk, and whether MidAmerican has any responsibility for remedial 
action. MidAmerican is currently conducting field investigations at seventeen 
of the sites and has completed investigations at one of the sites. In 
addition, MidAmerican has completed removals at three of the sites. 
MidAmerican is continuing to evaluate several of the sites to determine the 
future liability, if any, for conducting site investigations or other site 
activity. 

   MidAmerican's present estimate of probable remediation costs for the sites 
discussed above as of December 31, 1997 is $21 million. This estimate has 
been recorded as a liability and a regulatory asset for future recovery. The 
ICC has approved the use of a tariff rider which permits recovery of the 
actual costs of litigation, investigation and remediation relating to former 
MGP sites. MidAmerican's present rates in Iowa provide for a fixed annual 
recovery of MGP costs. MidAmerican intends to pursue recovery of the 
remediation costs from other PRPs and its insurance carriers. 

   The estimate of probable remediation costs is established on a site 
specific basis. The costs are accumulated in a three-step process. First, a 
determination is made as to whether MidAmerican has 

                              F-57           
<PAGE>
                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

potential legal liability for the site and whether information exists to 
indicate that contaminated wastes remain at the site. If so, the costs of 
performing a preliminary investigation and the costs of removing known 
contaminated soil are accrued. As the investigation is performed and if it is 
determined remedial action is required, the best estimate of remediation 
costs is accrued. If necessary, the estimate is revised when a consent order 
is issued. The estimated recorded liabilities for these properties include 
incremental direct costs of the remediation effort, costs for future 
monitoring at sites and costs of compensation to employees for time expected 
to be spent directly on the remediation effort. The estimated recorded 
liabilities for these properties are based upon preliminary data. Thus, 
actual costs could vary significantly from the estimates. The estimate could 
change materially based on facts and circumstances derived from site 
investigations, changes in required remedial action and changes in technology 
relating to remedial alternatives. In addition, insurance recoveries for some 
or all of the costs may be possible, but the liabilities recorded have not 
been reduced by any estimate of such recoveries. 

   Although the timing of potential incurred costs and recovery of such costs 
in rates may affect the results of operations in individual periods, 
management believes that the outcome of these issues will not have a material 
adverse effect on MidAmerican's financial position or results of operations. 

(C) CLEAN AIR ACT: 

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

   The impact of the new standards on MidAmerican will depend on the 
attainment status of the areas surrounding MidAmerican's operations and 
MidAmerican's relative contribution to the nonattainment status. If 
MidAmerican's operations contribute to nonattainment and modifications to 
MidAmerican's operations or facilities are necessary, the cost of making 
emissions reductions to meet the air quality standards will be dependent upon 
the level of emissions reductions required and the available technology. 
MidAmerican will continue to evaluate the potential impact of the new 
regulations. 

   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 significant 
contribution to nonattainment of NAAQS for ozone. Iowa is not subject to 
these emissions reduction requirements as EPA's rule is currently drafted, 
and, as such, MidAmerican does not anticipate that its facilities will be 
subject to additional emissions reductions as a result of this initiative. 
The EPA anticipates issuing its final rules in September 1998. MidAmerican 
will continue to closely monitor this rulemaking proceeding. 

(D) LONG-TERM POWER PURCHASE CONTRACT: 

   Payments to NPPD cover one-half of the fixed and operating costs of Cooper 
(excluding depreciation but including debt service) and MidAmerican's share 
of nuclear fuel cost (including nuclear fuel disposal) based on energy 
delivered. The debt service portion is approximately $1.5 million per month 
for 1998 and is not contingent upon the plant being in service. In addition, 
MidAmerican pays one-half of NPPD's decommissioning funding related to 
Cooper. 

   The debt amortization and Department of Energy (DOE) enrichment plant 
decontamination and decommissioning component of MidAmerican's payments to 
NPPD were $13.8 million, $14.5 million and $12.0 million and the net interest 
component was $3.8 million, $3.6 million and $4.6 million each for the years 
1997, 1996 and 1995, respectively. 

                              F-58           
<PAGE>
                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

   MidAmerican's payments for the debt principal portion of the power 
purchase contract obligation and the DOE enrichment plant decontamination and 
decommissioning payments are $14.4 million, $15.0 million, $15.8 million, 
$16.6 million, $17.4 million and $18.3 million for 1998 through 2003, 
respectively. 

(E) DECOMMISSIONING COSTS: 

   Based on site-specific decommissioning studies that include 
decontamination, dismantling, site restoration and dry fuel storage cost, 
MidAmerican's share of expected decommissioning costs for Cooper and Quad 
Cities, in 1997 dollars, is $247 million and $230 million, respectively. In 
Illinois, nuclear decommissioning costs are included in customer billings 
through a mechanism that permits annual adjustments. Such costs are reflected 
as base rates in Iowa tariffs. 

   For purposes of developing a decommissioning funding plan for Cooper, NPPD 
assumes that decommissioning costs will escalate at an annual rate of 4.0%. 
Although Cooper's operating license expires in 2014, the funding plan assumes 
decommissioning will start in 2004, the anticipated plant shutdown date. 

   As of December 31, 1997, MidAmerican's share of funds set aside by NPPD in 
internal and external accounts for decommissioning was $78.2 million. In 
addition, the funding plan also assumes various funds and reserves currently 
held to satisfy NPPD bond resolution requirements will be available for plant 
decommissioning costs after the bonds are retired in early 2004. The funding 
schedule assumes a long-term return on funds in the trust of 6.75% annually. 
Certain funds will be required to be invested on a short-term basis when 
decommissioning begins and are assumed to earn at a rate of 4.0% annually. 
NPPD is recognizing decommissioning costs over the life of the power sales 
contract. MidAmerican makes payments to NPPD related to decommissioning 
Cooper. These payments are included in MidAmerican's power purchase costs. 
The Cooper decommissioning component of MidAmerican's payments to NPPD was 
$11.3 million, $9.9 million and $8.9 million for the years 1997, 1996, and 
1995, respectively, and is included in Other Operating Expenses in the 
Consolidated Statements of Income. Earnings from the internal and external 
trust funds, which are recognized by NPPD as the owner of the plant, are tax 
exempt and serve to reduce future funding requirements. 

   External trusts have been established for the investment of funds for 
decommissioning the Quad Cities units. The total accrued balance as of 
December 31, 1997, was $93.3 million and is included in Other Liabilities and 
a like amount is reflected in Investments and represents the value of the 
assets held in the trusts. 

   MidAmerican's provision for depreciation included costs for Quad Cities 
nuclear decommissioning of $9.8 million, $8.6 million and $8.6 million for 
1997, 1996 and 1995, respectively. The provision charged to expense is equal 
to the funding that is being collected in rates. The decommissioning funding 
component of MidAmerican's Illinois tariffs assumes decommissioning costs, 
related to the Quad Cities unit, will escalate at an annual rate of 5.3% and 
the assumed annual return on funds in the trust is 6.5%. The Quad Cities 
decommissioning funding component of MidAmerican's Iowa tariffs assumes 
decommissioning costs will escalate at an annual rate of 6.3% and the assumed 
annual return on funds in the trust is 6.5%. Earnings on the assets in the 
trust fund were $5.0 million, $3.5 million and $2.5 million for 1997, 1996 
and 1995, respectively. 

(F) NUCLEAR INSURANCE: 

   MidAmerican maintains financial protection against catastrophic loss 
associated with its interest in Quad Cites and Cooper through a combination 
of insurance purchased by NPPD (the owner and operator of Cooper) and 
Commonwealth Edison (the joint owner and operator of Quad Cities), insurance 

                              F-59           
<PAGE>
                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

purchased directly by MidAmerican, and the mandatory industry-wide loss 
funding mechanism afforded under the Price-Anderson Amendments Act of 1988. 
The coverage falls into three categories: nuclear liability, property 
coverage and nuclear worker liability. 

   NPPD and Commonwealth Edison each purchase nuclear liability insurance in 
the maximum available amount of $200 million. In accordance with the 
Price-Anderson Amendments Act of 1988, excess liability protection above that 
amount is provided by a mandatory industry-wide program under which the 
owners of nuclear generating facilities could be assessed for liability 
incurred due to a serious nuclear incident at any commercial nuclear reactor 
in the United States. Currently, MidAmerican's maximum potential share of 
such an assessment is $79.3 million per incident, payable in installments not 
to exceed $10 million annually. 

   The property coverage provides for property damage, stabilization and 
decontamination of the facility, disposal of the decontaminated material and 
premature decommissioning. For Quad Cities, Commonwealth Edison purchases 
primary and excess property insurance protection for the combined interest in 
Quad Cities totalling $2.1 billion. For Cooper, NPPD purchases primary 
property insurance in the amount of $500 million. Additionally, MidAmerican 
and NPPD separately purchase coverage for their respective obligation of 
$1.125 billion each in excess of the $500 million primary layer purchased by 
NPPD. This structure provides that both MidAmerican and NPPD are covered for 
their respective 50% obligation in the event of a loss totalling $2.75 
billion. MidAmerican also directly purchases extra expense/business 
interruption coverage to cover the cost of replacement power and/or other 
continuing costs in the event of a covered accidental outage at Cooper or 
Quad Cities. The coverages purchased directly by MidAmerican, and the primary 
and excess property coverages purchased by Commonwealth Edison, contain 
provisions for retrospective premium assessments should two or more full 
policy-limit losses occur in one policy year. Currently, the maximum 
retrospective amounts that could be assessed against MidAmerican from 
industry mutual insurance companies for its obligations associated with 
Cooper and Quad Cities combined total $11.6 million. 

   The master nuclear worker liability coverage is an industry-wide policy 
with an aggregate limit of $200 million for the nuclear industry as a whole, 
which is in effect to cover tort claims of workers as a result of radiation 
exposure on or after January 1, 1988. MidAmerican's share, based on its 
interest in Cooper and Quad Cities, of a maximum potential share of a 
retrospective assessment under this program is $3.0 million. 

(G) COAL AND NATURAL GAS CONTRACT COMMITMENTS: 

   MidAmerican has entered into supply and related transportation contracts 
for its fossil fueled generating stations. The contracts, with expiration 
dates ranging from 1998 to 2003, require minimum payments of $132.2 million, 
$88.8 million, $57.8 million, $26.3 million and $3.1 million and $3.1 million 
for the years 1998 through 2003, respectively. The Company expects to 
supplement these coal contracts with spot market purchases to fulfill its 
future fossil fuel needs. 

   The Company has entered into various natural gas supply and transportation 
contracts for its utility operations. The minimum commitments under these 
contracts are $88 million, $63 million, $37 million, $32 million and $16 
million for the years 1998 through 2002, respectively, and $76 million for 
the total of the years thereafter. During 1993 FERC Order 636 became 
effective, requiring interstate pipelines to restructure their services. The 
pipeline will recover the transition costs related to Order 636 from the 
local distribution companies. The Company has recorded a liability and 
regulatory asset for the transition costs which are being recovered by the 
Company through the purchased gas adjustment clause. The unrecovered balance 
recorded by the Company as of December 31, 1997, was $9.3 million.

(6) RETIREMENT PLANS: 

   The Company has noncontributory defined benefit pension plans covering 
substantially all employees. Benefits under the plans are based on 
participants' compensation, years of service and age at retirement. 

   Funding is based upon the actuarially determined costs of the plans and 
the requirements of the Internal Revenue Code and the Employee Retirement 
Income Security Act. MidAmerican has been allowed to recover funding 
contributions in rates.

</TABLE>

   During 1995, the Company incurred a one-time charge of $15.7 million 
related to the early retirement portion of its restructuring plan. Of such 
cost, $3.0 million was charged to expense and the remaining amount was 
deferred for future recovery through the regulatory process. 

   The plan assets are stated at fair market value and are primarily 
comprised of insurance contracts, United States government debt and corporate 
equity securities. The plans in which accumulated benefits exceed assets 
consist entirely of nonqualified defined benefit plans. Although the plans 
have no assets, the Company purchases corporate owned life insurance to 
provide funding for the future cash requirements. The cash value of such 
insurance was $21.5 million and $17.3 million at December 31, 1997 and 1996,

   The Company currently provides certain health care and life insurance 
benefits for retired employees. Under the plans, substantially all of the 
Company's employees may become eligible for these benefits if they reach 
retirement age while working for the Company. However, the Company retains 
the right to change these benefits anytime at its discretion. 

   In January 1993, the Company adopted SFAS No. 106, Employers Accounting 
for Postretirement Benefits Other Than Pensions. The Company began expensing 
these costs on an accrual basis for its Illinois customers and certain of its 
Iowa customers in 1993 and including provisions for such costs in rates for 
these customers. For its remaining Iowa customers, the Company deferred the 
portion of these costs above the "pay-as-you-go" amount already included in 
rates until recovery on an accrual basis was established in 1995. The Company 
is currently amortizing the deferral, expensing the SFAS No. 106 accrual and 
including provisions for these costs in rates.

   During 1995, the Company recorded a one-time expense of $4.4 million 
related to the early retirement portion of its restructuring plan. 

   The Company has established external trust funds to meet its expected 
postretirement benefit obligations. The trust funds are comprised primarily 
of guaranteed rate investment accounts and money market investment accounts. 
A reconciliation of the funded status of the plan to the amounts realized as 
of December 31 is presented below (dollars in thousands):

   For purposes of calculating the postretirement benefit obligation, it is 
assumed health care costs for covered individuals prior to age 65 will 
increase by 10.0% in 1998, and that the rate of increase thereafter will 
decline by 1.0% annually to an ultimate rate of 5.5% by the year 2003. For 
covered individuals age 65 and older, it is assumed health care costs will 
increase by 7.0% in 1998, and that the rate of increase thereafter will 
decline by 1.0% annually to an ultimate rate of 5.5% by the year 2000. 

   If the assumed health care trend rates used to measure the expected cost 
of benefits covered by the plans were increased by 1%, the total service and 
interest cost would increase by $1.8 million and the accumulated 
postretirement benefit obligation would increase by $15.4 million.

   The Company sponsors defined contribution pension plans (401(k) plans) 
covering substantially all employees. The Company's contributions to the 
plans, which are based on the participants' level of contribution and cannot 
exceed four percent of the participants' salaries or wages, were $4.6 
million, $4.4 million and $3.7 million for 1997, 1996 and 1995, respectively. 

(7) STOCK-BASED COMPENSATION PLANS: 

   The company has stock-based compensation arrangements as described below. 
The company accounts for these plans under Accounting Principles Board 
Opinion No. 25 and the related interpretations. The total compensation cost 
recognized in income for stock-based compensation awards was $1.3 million, 
$0.6 million, and $1.8 million for 1997, 1996, and 1995 respectively. Had the 
company used Statement of Accounting Standards No. 123, "Accounting for 
Stock-Based Compensation" (SFAS 123), pro-forma net income for common stock 
would be $135.3 million, $130.9 million, and $122.6 million, while earnings 
per share would be $1.38, $1.30, and $1.22 for the years ended 1997, 1996, 
and 1995 respectively. 

   Stock options and performance share awards have been granted pursuant to 
the MidAmerican Energy Company 1995 Long-Term Incentive Plan (the "Plan"). Up 
to four million shares are authorized to be granted under the Plan. 

Stock Options -- Under the Plan, the Board of Directors have granted options 
to purchase shares of MidAmerican Holdings common stock (the "Options") at 
the fair market value of the shares on the date of the grant. The options 
vest over a 4-year period at a rate of 25% per year and expire ten years 
after the date of grant. Stock option activity for 1997, 1996, and 1995 is 
summarized as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

   On June 27, 1997, the Iowa Utilities Board (IUB) issued an order in a 
consolidated rate proceeding involving MidAmerican's pricing proposal and a 
filing by the Iowa Office of Consumer Advocate (OCA). The order approved a 
March 1997 settlement agreement between MidAmerican, the OCA and other 
parties to the proceeding. The agreement includes a number of characteristics 
of MidAmerican's pricing proposal. Prices for residential customers were 
reduced $8.5 million annually and $10.0 million annually, effective November 
1, 1996, and July 11, 1997, respectively, and will be reduced an additional 
$5.0 million annually on June 1, 1998, for a total annual decrease of $23.5 
million. Rates for commercial and industrial customers will be reduced a 
total of $10 million annually by June 1, 1998, through pilot projects, 
negotiated rates with individual customers and, if needed, a base rate 
reduction effective June 1, 1998. The agreement includes a tracking mechanism 
to currently recover the cost of capital improvements required by the Cooper 
Nuclear Station Power Purchase Contract. The tracking mechanism will offset 
approximately $9 million of these reductions. 

   In addition, the agreement accepted MidAmerican's proposal to eliminate 
the Iowa energy adjustment clause (EAC) which was the mechanism through which 
fuel costs were collected from Iowa customers prior to July 11, 1997. The EAC 
flows the cost of fuel to customers on a current basis, and thus, fuel costs 
had little impact on net income. Prospectively, base rates for Iowa customers 
will include a factor for recovery of a representative level of fuel costs. 
To the extent actual fuel costs vary from that factor, pre-tax earnings will 
be impacted. The fuel cost factor will be reviewed in February 1999 and 
adjusted prospectively if actual 1998 fuel costs vary 15% above or below the 
factor included in base rates. 

   Under the agreement, if MidAmerican's annual Iowa electric jurisdictional 
return on common equity exceeds 12%, then an equal sharing between customers 
and shareholders of earnings above the 12% level begins; if it exceeds 14%, 
then two-thirds of MidAmerican's share of those earnings will be used for 
accelerated recovery of certain regulatory assets. The agreement permits 
MidAmerican to file for increased rates if the return falls below 9%. Other 
parties signing the agreement are prohibited from filing for reduced rates 
prior to 2001 unless the return, after reflecting credits to customers, 
exceeds 14%. 

   The agreement also provides that MidAmerican will develop a pilot program 
for a market access service which allows customers with at least 4 MW of load 
to choose energy suppliers. The pilot program, which is subject to approval 
by the IUB and the Federal Energy Regulatory Commission (FERC), is limited to 
60 MW of participation the first year and can be expanded by 15 MW annually 
until the conclusion of the program. Any loss of revenues associated with the 
pilot program will be considered part of the $10 million annual reduction for 
commercial and industrial customers as described above, but may not be 
recovered from other customer classes. The program was filed with the IUB and 
the FERC in September 1997. The Company anticipates that the necessary 
approvals will be received before the end of the second quarter of 1998. 

(10) DISCONTINUED OPERATIONS: 

   In the third quarter of 1996, the Company announced the discontinuation of 
certain nonstrategic businesses in support of its strategy of becoming the 
leading regional energy and complementary services provider. In November of 
1996, the Company signed a definitive agreement with KCS Energy, Inc. (KCS) 
to sell an oil and gas exploration and development subsidiary and completed 
the sale on January 3, 1997. The Company recorded an after-tax loss of $7.1 
million for the disposition in 1996 and an additional $0.9 million in 1997. 
In October 1997, the company sold its subsidiary that developed and continues 
to operate a computerized information system facilitating the real-time 
exchange of power in the electric industry. The Company recorded a $4.0 
million estimated after-tax loss on disposal in the third quarter of 1996 and 
an additional $3.2 million in September 1997. In addition, in the third 
quarter of 1996 the Company received a final settlement from the sale of a 
coal mining subsidiary which was reflected as a discontinued operation by a 
predecessor company in 1982. The final settlement, which resulted in an 
after-tax loss of $3.3 million, included the reacquisition of preferred 
equity by the buyer and the settlement of reclamation reserves.

(14) FAIR VALUE OF FINANCIAL INSTRUMENTS: 

   The following methods and assumptions were used to estimate the fair value 
of each class of financial instruments. Tariffs for the Company's utility 
services are established based on historical cost ratemaking. Therefore, the 
impact of any realized gains or losses related to financial instruments 
applicable to the Company's utility operations is dependent on the treatment 
authorized under future ratemaking proceedings. 

   Cash and cash equivalents -- The carrying amount approximates fair value 
due to the short maturity of these instruments. 

   Quad Cities nuclear decommissioning trust fund -- Fair value is based on 
quoted market prices of the investments held by the fund. 

   Marketable securities -- Fair value is based on quoted market prices. 

   Debt securities -- Fair value is based on the discounted value of the 
future cash flows expected to be received from such investments. 

   Equity investments carried at cost -- Fair value is based on an estimate 
of the Company's share of partnership equity, offers from unrelated third 
parties or the discounted value of the future cash flows expected to be 
received from such investments.

                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

   Notes payable -- Fair value is estimated to be the carrying amount due to 
the short maturity of these issues. 

   Preferred shares -- Fair value of preferred shares with mandatory 
redemption provisions is estimated based on the quoted market prices for 
similar issues. 

   Long-term debt -- Fair value of long-term debt is estimated based on the 
quoted market prices for the same or similar issues or on the current rates 
offered to the Company for debt of the same remaining maturities. 

   The following table presents the carrying amount and estimated fair value 
of certain financial instruments as of December 31 (in thousands):

   Included in investments on the Consolidated Balance Sheets is the 
Company's investment in common stock of McLeodUSA Incorporated (McLeodUSA). 
McLeodUSA common stock has been publicly traded since June 14, 1996. Investor 
agreements related to McLeodUSA's initial public offering and subsequent 
merger with Consolidated Communications Inc. prohibit the Company from 
selling or otherwise disposing of any of the common stock of McLeodUSA prior 
to September 24, 1998, without approval of McLeodUSA's board of directors. As 
a result of the agreements, the Company's investment was considered 
restricted stock and as such, was recorded at cost in all periods prior to 
September 1997. Beginning in September 1997, the investment is no longer 
considered restricted for accounting purposes and is recorded at fair value. 
At December 31, 1997 the cost and fair value of the McLeodUSA investment were 
$45.2 million and $257.9 million, respectively. The unrealized gain is 
recorded, net of income taxes, as a valuation allowance in common 
shareholders' equity. At December 31, 1997, the net unrealized gain and 
deferred income taxes for this investment were $212.7 million and $74.4 
million, respectively.

(17) MIDAMERICAN-OBLIGATED MANDATORILY REDEEMABLE PREFERRED 
     SECURITIES OF MIDAMERICAN ENERGY FINANCING I: 

   In December 1996, MidAmerican Energy Financing I (the Trust), a 
wholly-owned statutory business trust of MidAmerican, issued 4,000,000 shares 
of 7.98% Series MidAmerican-obligated mandatorily redeemable preferred 
securities (the Preferred Securities). The sole assets of the Trust are 
$103.1 million of MidAmerican 7.98% Series A Debentures due 2045 (the 
Debentures). There is a full and unconditional guarantee by MidAmerican of 
the Trust's obligations under the Preferred Securities. MidAmerican has the 
right to defer payments of interest on the Debentures by extending the 
interest payment period for up to 20 consecutive quarters. If interest 
payments on the Debentures are deferred, distributions on the Preferred 
Securities will also be deferred. During any deferral, distributions will 
continue to accrue with interest thereon and MidAmerican may not declare or 
pay any dividend or other distribution on, or redeem or purchase, any of its 
capital stock. 

   The Debentures may be redeemed by MidAmerican on or after December 18, 
2001, or at an earlier time if there is more than an insubstantial risk that 
interest paid on the Debentures will not be deductible for federal income tax 
purposes. If the Debentures, or a portion thereof, are redeemed, the Trust 
must redeem a like amount of the Preferred Securities. If a termination of 
the Trust occurs, the Trust will distribute to the holders of the Preferred 
Securities a like amount of the Debentures unless such a distribution is 
determined not to be practicable. If such determination is made, the holders 
of the Preferred Securities will be entitled to receive, out of the assets of 
the trust after satisfaction of its liabilities, a liquidation amount of $25 
for each Preferred Security held plus accrued and unpaid distributions.

(18) SALE OF ACCOUNTS RECEIVABLE: 

   In 1997 MidAmerican 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 MidAmerican. Funding Corp. in turn has sold receivable interests to 
outside investors. In consideration of the sale, MidAmerican 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 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 MidAmerican or its 
creditors and, as such, the accounts receivable sold are not reflected on 
Holdings' or MidAmerican's Consolidated Balance Sheets. At December 31, 1997, 
$130.0 million, net of reserves, was sold under the agreement.

                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

A) GENERAL: 

   The consolidated financial statements included herein have been prepared 
by Holdings, without audit, pursuant to the rules and regulations of the 
Securities and Exchange Commission. Certain information and disclosures 
normally included in financial statements prepared in accordance with 
generally accepted accounting principles have been condensed or omitted 
pursuant to such rules and regulations. In the opinion of the Company, all 
adjustments have been made to present fairly the financial position, the 
results of operations, comprehensive income and the changes in cash flows for 
the periods presented. Although the Company believes that the disclosures are 
adequate to make the information presented not misleading, it is suggested 
that these financial statements be read in conjunction with the consolidated 
financial statements and the notes thereto included in the Company's latest 
Annual Report on Form 10-K. 

B) ENVIRONMENTAL MATTERS: 

   1) Manufactured Gas Plant Facilities: 

   The United States Environmental Protection Agency (EPA) and the state 
environmental agencies have determined that contaminated wastes remaining at 
certain decommissioned manufactured gas plant (MGP) facilities may pose a 
threat to the public health or the environment if such contaminants are in 
sufficient quantities and at such concentrations as to warrant remedial 
action. 

   MidAmerican is evaluating 27 properties which were, at one time, sites of 
gas manufacturing plants in which it may be a potentially responsible party 
(PRP). The purpose of these evaluations is to determine whether waste 
materials are present, whether such materials constitute an environmental or 
health risk, and whether MidAmerican has any responsibility for remedial 
action. MidAmerican is currently conducting field investigations at seventeen 
of the sites and has completed investigations at one of the sites. In 
addition, MidAmerican has completed removals at three of the sites. 
MidAmerican is continuing to evaluate several of the sites to determine its 
responsibility, if any, for conducting site investigations or other site 
activity. 

   MidAmerican's present estimate of probable remediation costs for the sites 
discussed above as of June 30, 1998 is $25 million. This estimate has been 
recorded as a liability and a regulatory asset for future recovery. The 
Illinois Commerce Commission (ICC) has approved the use of a tariff rider 
which permits recovery of the actual costs of litigation, investigation and 
remediation relating to former MGP sites. MidAmerican's present rates in Iowa 
provide for a fixed annual recovery of MGP costs. MidAmerican intends to 
pursue recovery of the remediation costs from other PRPs and its insurance 
carriers. 

   The estimate of probable remediation costs is established on a site 
specific basis. The costs are accumulated in a three-step process. First, a 
determination is made as to whether MidAmerican has potential legal liability 
for the site and whether information exists to indicate that contaminated 
wastes remain at the site. Second, if potential legal liability exists, the 
costs of performing a preliminary investigation and the costs of removing 
known contaminated soil are accrued. Finally, as the investigation is 
performed and if it is determined remedial action is required, the best 
estimate of remediation costs is accrued. If necessary, the estimate is 
revised when a consent order is issued. The estimated recorded liabilities 
for these properties include incremental direct costs of the remediation 
effort, costs for future monitoring at sites and costs of compensation to 
employees for time expected to be spent directly on the remediation effort. 
The estimated recorded liabilities for these properties are based upon 
preliminary data. Thus, actual costs could vary significantly from the 
estimates. The estimate could change materially based on facts and 
circumstances derived from site investigations, changes in required remedial 
action and changes in technology relating to remedial alternatives. In 
addition, insurance recoveries for some or all of the costs may be possible, 
but the liabilities recorded have not been reduced by any estimate of such 
recoveries.

                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

B) ENVIRONMENTAL MATTERS:  (Continued) 

    Although the timing of potential incurred costs and recovery of such 
costs in rates may affect the results of operations in individual periods, 
management believes that the outcome of these issues will not have a material 
adverse effect on MidAmerican's financial position or results of operations. 

   2) Clean Air Act: 

   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 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. 

   The impact of the new standards on MidAmerican will depend on the 
attainment status of the areas surrounding MidAmerican's operations and 
MidAmerican's relative contribution to the nonattainment status. The 
attainment status of areas in the state of Iowa will not be known for two to 
three years. However, if MidAmerican's operations are determined to 
contribute to nonattainment, the installation of additional control 
equipment, such as scrubbers and/or selective catalytic reduction, on 
MidAmerican's units could be required. The cost to install such equipment 
could be significant. MidAmerican will continue to follow the attainment 
status of the areas in which it operates and evaluate the potential impact of 
the status of these areas on MidAmerican under the new regulations. 

   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 significant 
contribution to nonattainment of NAAQS for ozone. Iowa is not subject to 
these emissions reduction requirements as EPA's rule is currently drafted, 
and, as such, MidAmerican does not anticipate that its facilities will be 
subject to additional emissions reductions as a result of this initiative. 
The EPA anticipates issuing its final rules in September 1998. MidAmerican 
will continue to closely monitor this rulemaking proceeding. 

C) RATE MATTERS: 

   As a result of a negotiated settlement in Illinois, MidAmerican reduced 
its Illinois electric service rates by annual amounts of $13.1 million and 
$2.4 million, effective November 3, 1996, and June 1, 1997, respectively. 

   On June 27, 1997, the IUB approved a March 1997 settlement agreement 
between MidAmerican, the Iowa Office of Consumer Advocate (OCA) and other 
parties in a consolidated rate proceeding involving MidAmerican's electric 
pricing proposal and a filing by the OCA. The agreement includes a number of 
components of MidAmerican's pricing proposal. Six major components of the 
settlement and their status are as follows: 

   1) On an annualized basis, prices for residential customers were reduced 
$8.5 million, $10.0 million and $5.0 million effective November 1, 1996, July 
11, 1997, and June 1, 1998 respectively, for a total annual decrease of $23.5 
million. 

   2) Rates for industrial customers will be reduced by $6 million annually 
and rates for commercial customers will be reduced by $4 million annually. 
MidAmerican has been given permission to implement these reductions through a 
retail access pilot project and through negotiated individual contracts. In 
the event that these contracts in the aggregate do not reduce rates by $6 
million and $4 million, respectively, MidAmerican is required to apply any 
remaining amount to across-the-board rate reductions to customers who do not 
enter into contracts. 

                              F-82

                     MIDAMERICAN ENERGY HOLDINGS COMPANY 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

C) RATE MATTERS:  (Continued) 

    The effective date for these rate reductions was set for June 1, 1998 in 
the IUB Order approving the settlement. However, MidAmerican has pending 
before the IUB a request to extend the deadlines until September 1, 1998 for 
industrial customers, and December 31, 1998 for commercial customers. That 
request would involve an obligation to increase the amount of the reduction 
on a one-time basis to reflect the time value of money between June 1, 1998 
and the new requested deadlines. MidAmerican estimates it will not have any 
interest obligation with respect to the industrial contracts, and will not 
incur any material interest obligation with respect to its commercial 
contracts. 

   The negotiated 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 
MidAmerican incurs to fulfill these contracts will vary. On an aggregate 
basis the annual revenues under contract are approximately $125 million. 

   The IUB is currently considering the contracting process in two 
proceedings. The outcome of those proceedings could impact further 
contracting efforts, as well as determine whether any of the contracts will 
need to be renegotiated, and the extent to which the annualized rate 
reduction will take the form of negotiated contracts versus across-the-board 
rate reductions. 

   3) A tracking mechanism (Cooper Tracker) is being used to currently 
recover costs for capital improvements required by the Cooper Nuclear Station 
Power Purchase Contract which will offset approximately $6 million of the 
rate reductions in 1998. Other operating expenses will correspondingly 
increase due to currently expensing the related costs. 

   4) Elimination of the Iowa energy adjustment clause (EAC). Prior to July 
11, 1997, MidAmerican collected fuel costs from Iowa customers on a current 
basis through the EAC, and thus, fuel costs had little impact on net income. 
Since then, base rates for Iowa customers include a factor for recovery of a 
representative level of fuel costs. To the extent actual fuel costs vary from 
that factor, pre-tax earnings are impacted. The fuel cost factor will be 
reviewed in February 1999 and adjusted prospectively if actual 1998 fuel 
costs vary 15% above or below the factor included in base rates. 

   5) If MidAmerican's annual Iowa electric jurisdictional return on common 
equity exceeds 12%, then an equal sharing between customers and shareholders 
of earnings above the 12% level begins; if it exceeds 14%, then two-thirds of 
MidAmerican's share of those earnings will be used for accelerated recovery 
of certain regulatory assets. The agreement permits MidAmerican to file for 
increased rates if the return falls below 9%. Other parties signing the 
agreement are prohibited from filing for reduced rates prior to 2001 unless 
the return, after reflecting credits to customers, exceeds 14%. 

   6) MidAmerican will develop a pilot program for a market access service 
which allows customers with at least 4 MW of load to choose energy suppliers. 
The pilot program, which is subject to approval by the IUB and the Federal 
Energy Regulatory Commission (FERC), is limited to 60 MW of participation the 
first year and can be expanded by 15 MW annually until the conclusion of the 
program. Any loss of revenues associated with the pilot program will be 
considered part of the $10 million annual reduction for commercial and 
industrial customers as described above, but may not be recovered from other 
customer classes. The program was filed with the IUB and the FERC in 
September 1997. The Company anticipates that the necessary approvals will be 
received by the fourth quarter of 1998. 

D) ACCOUNTING FOR THE EFFECTS OF CERTAIN TYPES OF REGULATION: 

   Statement of Financial Accounting Standards (SFAS) No. 71 sets forth 
accounting principles for operations that are regulated and meet certain 
criteria. For operations that meet the criteria, SFAS 71 

                              F-83

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 

D) ACCOUNTING FOR THE EFFECTS OF CERTAIN TYPES OF REGULATION:  (Continued) 

 allows, among other things, the deferral of costs that would otherwise be 
expensed when incurred. A possible consequence of the changes in the utility 
industry is the discontinued applicability of SFAS 71. The majority of 
MidAmerican's electric and gas utility operations currently meet the criteria 
of SFAS 71, but its applicability is periodically reexamined. On December 16, 
1997, MidAmerican's generation operations serving Illinois were no longer 
subject to the provisions of SFAS 71 due to passage of restructuring 
legislation in Illinois. Thus, MidAmerican was required to write off 
regulatory assets and liabilities from its balance sheet related to its 
Illinois generation operations. The net amount of such write-offs were 
immaterial. If other utility operations no longer meet the criteria of SFAS 
71, MidAmerican would 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 June 30, 1998, MidAmerican had 
approximately $312 million of regulatory assets in its Consolidated Balance 
Sheet because these costs are expected to be recovered in future charges to 
utility customers. 

E) MIDAMERICAN-OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES: 

   The MidAmerican Obligated Mandatorily Redeemable Preferred Securities of 
Subsidiary Trust Holding Solely MidAmerican Junior Subordinated Debentures 
included in the Consolidated Balance Sheets were issued by MidAmerican Energy 
Financing I (the Trust), a wholly-owned statutory business trust of 
MidAmerican. The sole assets of the Trust are $103.1 million of MidAmerican 
7.98% Series A Debentures due 2045. 

F) COMMON SHAREHOLDERS' EQUITY: 

   In March 1997, Holdings announced its plan to repurchase up to $200 
million of the Company's common stock. The Company plans to purchase the 
shares from time to time as market conditions warrant. As of June 30, 1998, 
the Company had repurchased approximately 6.2 million shares for $114.8 
million under the plan. In addition, a subsidiary has acquired 437,131 shares 
of Holdings common stock which are also excluded from shares outstanding. 

G) DETAIL OF OTHER COMPREHENSIVE INCOME -- INCOME TAXES: 

   For fiscal years beginning after December 15, 1997, full sets of 
general-purpose financial statements are required to display comprehensive 
income and its components in a financial statement that is displayed with the 
same prominence as the other financial statements. Comprehensive income 
refers, in general, to changes in the Company's equity, except those 
resulting from transactions with shareholders. "Unrealized holding gains 
(losses)" reflects the overall increase (decrease) in the market value of 
marketable securities held by the Company as available-for-sale. The 
"reclassification adjustment" removes any gains (losses) that have been 
realized from sales of those securities and reflected in the Company's Net 
Income.

H) MCLEODUSA INCORPORATED INVESTMENT: 

   Included in investments on the Consolidated Balance Sheets is the 
Company's investment in common stock of McLeodUSA Incorporated (McLeodUSA). 
McLeodUSA common stock has been publicly traded since June 14, 1996. Investor 
agreements related to McLeodUSA's initial public offering and subsequent 
merger with Consolidated Communications Inc. prohibit the Company from 
selling or otherwise disposing of any of the common stock of McLeodUSA prior 
to September 24, 1998, without approval of McLeodUSA's board of directors. As 
a result of the agreements, the Company's investment was considered 
restricted stock and, as such, was recorded at cost in all periods prior to 
September 1997. Beginning in September 1997, the investment is no longer 
considered restricted for accounting purposes and is recorded at fair value. 
At June 30, 1998, the cost and fair value of the McLeodUSA investment were 
$45.2 million and $313.3 million, respectively. The unrealized gain is 
recorded, net of income taxes, as accumulated comprehensive income in common 
shareholders' equity. At June 30, 1998, the unrealized gain and deferred 
income taxes for this investment were $268.1 million and $93.8 million, 
respectively. 

I) SUBSEQUENT EVENT: 

   On August 11, 1998, a definitive merger agreement was entered into between 
the Company and CalEnergy, a global provider of energy services. Under the 
terms of the agreement, the shareholders of the Company will receive $27.15 
cash for each share of their common stock reflecting a 36 percent premium 
over the August 11, 1998 closing price. The merger will need to be approved 
by the shareholders of both companies, the Federal Energy Regulatory 
Commission, and the Nuclear Energy Regulatory Commission. Filings will also 
be made with the Iowa Utilities Board, which has the right to review the 
merger and to disapprove it only if found not in the public interest, the 
Federal Trade Commission and the Department of Justice. State regulators in 
Illinois will be notified of the merger. Management believes completion of 
the merger could occur by the first quarter of 1999.

   The following unaudited pro forma combined condensed financial statements 
are based on the historical consolidated financial statements of CalEnergy 
and MidAmerican, combined and adjusted to give effect on a pro forma basis to 
the Securities Offering and expected refinancing of the Senior Discount 
Notes, and on a pro forma as adjusted basis, to those transactions and the 
MidAmerican Merger and the transactions contemplated thereby (including the 
related financing), as described in the notes thereto. Certain amounts in the 
MidAmerican financial statements have been reclassified to conform to 
CalEnergy's presentation. These statements should be read in conjunction with 
the historical financial statements and notes thereto which are included and 
incorporated by reference in this Prospectus Supplement. See "Incorporation 
by Reference." 

   The unaudited pro forma combined condensed statements of earnings for the 
year ended December 31, 1997 and for the six months ended June 30, 1998 
present the results for CalEnergy and MidAmerican as if the MidAmerican 
Merger had occurred at the beginning of each period presented. The 
accompanying unaudited pro forma combined condensed balance sheet as of June 
30, 1998 gives effect to the MidAmerican Merger as of that date. 

   The pro forma adjustments are based upon preliminary estimates, 
information currently available and certain assumptions that management 
believes are reasonable under the circumstances. CalEnergy's actual 
consolidated financial statements will reflect the effects of the MidAmerican 
Merger on and after the effective time of the MidAmerican Merger rather than 
the dates indicated above. The unaudited pro forma combined condensed 
financial statements neither purport to represent what the combined results 
of operations or financial condition actually would have been had the 
MidAmerican Merger and related transactions in fact occurred on the assumed 
dates, nor to project the combined results of operations and financial 
position for any future period. 

   The MidAmerican Merger will be accounted for by the purchase method and, 
therefore, assets and liabilities of MidAmerican will be recorded at their 
fair values. The excess of the purchase cost over the fair value of net 
assets acquired at the effective time of the MidAmerican Merger will be 
recorded as goodwill. Allocations included in the pro forma statements are 
based on analysis which is not yet completed. Accordingly, the final value of 
the purchase price and its allocation may differ, perhaps significantly, from 
the amounts included in these pro forma statements. 

   At the effective time of the MidAmerican Merger, the MidAmerican 
shareholders will receive $27.15 in cash for each issued and outstanding 
share of MidAmerican common stock. The pro forma combined condensed financial 
statements assume that all MidAmerican shares were tendered for the cash 
consideration of $27.15 per share. The total consideration for the 
transaction using this value was approximately $2.6 billion.

        NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA 

   The Unaudited Pro Forma Combined Condensed Financial Data are based on the 
following assumptions: 
1.     Issuance of $1,400 million 7.5% senior debt, net of $27 million debt 
       issue costs. (The actual weighted average interest rate for the 
       Securities is approximately 7.7%.) 
2.     Retirement of the $529.6 million 10.25% Senior Discount Notes including 
       a call premium of $27.1 million and write off of deferred financing 
       costs of $6.1 million. 
3.     Issuance of $750 million 6.5% notes of a subsidiary, prior to the 
       MidAmerican Merger, net of $10 million debt issue costs. 
4.     Issuance of 16.57 million shares of Common Stock of CalEnergy for $450 
       million, net, and 8.75% preferred securities of a subsidiary trust for 
       $150 million net, prior to the MidAmerican Merger. 
5.     The use of the proceeds of the debt and equity offerings described 
       above to purchase MidAmerican for $2,587.1 million, including 
       transaction costs. 
6.     The preliminary adjustments which have been made to the assets and 
       liabilities of MidAmerican to reflect the effect of the acquisition 
       accounted for as a purchase business combination follow (in thousands):

</TABLE>

7.     A. Included in other assets is primarily an adjustment to reflect the 
          fair value of MidAmerican's investments in real estate. 
       B. Included in other liabilities are adjustments to reflect 
          MidAmerican's compensation obligations and to reflect MidAmerican's 
          long-term contracts at fair value based on the estimated market 
          prices for similar purchases with similar remaining maturities. 
       C. Record amortization of the excess purchase price over the net 
          assets acquired using the straight line method over 40 years. 
       D. Record amortization of the purchase price accounting adjustments 
          using the straight line or other applicable method over the 
          remaining estimated lives. 
       E. Includes income tax expense for the effects of the pro forma 
          adjustments which affect taxable income at an effective rate of 
          40%. Preferred dividends on the $150 million 8.75% preferred 
          securities are deductible for income tax purposes. 
       F. For the six months ended June 30, 1998, earning per share--diluted 
          is further adjusted for certain convertible securities which are 
          antidilutive on a pro forma and a pro forma as adjusted basis. 
8.     Excluding the $87.0 million Indonesian asset impairment charge from the 
       year ended December 31, 1997 actual, pro forma and pro forma as 
       adjusted amounts, basic earnings per share would have been $2.06, $1.60 
       and $2.12, respectively.

                           CALENERGY COMPANY, INC. 
              COMMON STOCK, PREFERRED STOCK AND DEBT SECURITIES 

   CalEnergy Company, Inc. (the "Company") may from time to time offer, 
together or separately, (i) shares of its common stock, par value $.0675 per 
share ("Common Stock"), (ii) shares of its preferred stock, no par value 
("Preferred Stock"), (iii) senior debt securities ("Senior Debt Securities") 
and (iv) subordinated debt securities ("Subordinated Debt Securities" and 
together with Senior Debt Securities, the "Debt Securities"). The Common 
Stock, the Preferred Stock and the Debt Securities are collectively referred 
to herein as the "Securities." The Securities in respect of which this 
Prospectus is being delivered (the "Offered Securities") may be offered, 
separately or together, in separate series, in amounts, at prices and on 
terms to be set forth in a supplement to this Prospectus (a "Prospectus 
Supplement"). 

   By separate prospectus, the form of which is included in the Registration 
Statement of which this Prospectus forms a part, three Delaware statutory 
business trusts (individually, a "CalEnergy Trust" and collectively, the 
"CalEnergy Trusts"), which are wholly owned subsidiaries of the Company, may 
from time to time severally offer preferred securities guaranteed by the 
Company to the extent set forth therein and the Company may offer from time 
to time junior subordinated debt securities either directly or to a CalEnergy 
Trust. The aggregate public offering price of the securities to be offered by 
this Prospectus and such other prospectus shall not exceed $1,926,587,500 (or 
its equivalent in one or more foreign currencies, currency units or composite 
currencies). 

   Specific terms of the Offered Securities in respect of which this 
Prospectus is being delivered will be set forth in an applicable Prospectus 
Supplement, that includes, where applicable, the following: (i) in the case 
of Common Stock, the specific designation, number of shares, purchase price 
and the rights and privileges thereof, together with any qualifications or 
restrictions thereon and any listing on a securities exchange; (ii) in the 
case of Preferred Stock, the specific designation, number of shares, purchase 
price and the rights, preferences and privileges thereof and any 
qualifications or restrictions thereon (including dividends, liquidation 
value, voting rights, terms for the redemption, conversion or exchange 
thereof and any other specific terms of the Preferred Stock) and any listing 
on a securities exchange; and (iii) in the case of the Debt Securities, the 
specific designation, aggregate principal amount, authorized denomination, 
maturity, premium, or discount, if any, exchangeability, redemption, 
conversion, prepayment or sinking fund provisions, if any, interest rate 
(which may be fixed or variable), if any, method, if any, of calculating 
interest payments and dates for payment thereof, dates on which premium, if 
any, will be payable, the right of the Company, if any, to defer payment of 
interest on the Debt Securities and the maximum length of such deferral 
period, the initial public offering price, any listing on a securities 
exchange and other specific terms of the offering. Unless otherwise indicated 
in the Prospectus Supplement, the Company does not intend to list any of the 
Securities other than the Common Stock on a national securities exchange. Any 
Prospectus Supplement relating to any series of Offered Securities will 
contain information, where applicable, concerning certain United States 
federal income tax considerations for the Offered Securities. 

   The Common Stock and Preferred Stock and Debt Securities offered pursuant 
to this Prospectus may be denominated in U.S. dollars or one or more foreign 
currencies, currency units or composite securities to be determined at or 
prior to the time of any offering. The Debt Securities offered pursuant to 
this Prospectus may consist of bonds, debentures, notes or other evidences of 
indebtedness in one or more series and in amounts, at prices and on terms to 
be determined at or prior to the time of any such offering. Unless otherwise 
disclosed in a Prospectus Supplement, the Company's obligations under the 
Senior Debt Securities will be unsecured obligations of the Company ranking 
pari passu in right of payment of principal and interest and with all other 
existing and future unsecured obligations of the Company. If security for the 
Debt Securities is to be provided it will be described in an applicable 
Prospectus Supplement. The Company's obligations under the Subordinated Debt 
Securities will be subordinated in right of payment to the prior payment in 
full of all Senior Debt. 

   The Offered Securities may be offered directly, through agents designated 
from time to time, to or through dealers or to or through underwriters. Such 
agents or underwriters may act alone or with other agents or underwriters. 
Any such agents, dealers or underwriters will be set forth in a Prospectus 
Supplement. If an agent of the Company, or a dealer or underwriter, is 
involved in the offering of the Offered Securities, the agent's commission, 
dealer's purchase price, underwriter's discount and net proceeds to the 
Company, as the case may be, will be set forth in, or may be calculated from, 
the Prospectus Supplement. Any underwriters, dealers or agents participating 
in the offering may be deemed "underwriters" within the meaning of the 
Securities Act of 1933, as amended (the "Securities Act").

                                 RISK FACT0RS 

   Prospective investors should carefully consider the risk factors set forth 
below, in addition to the other information appearing in or incorporated by 
reference in this Prospectus. This Prospectus contains or incorporates by 
reference forward-looking statements which involve risks and uncertainties. 
The Company's actual results in the future could differ significantly from 
the results discussed or implied in the forward-looking statements. Factors 
that could cause or contribute to such a difference include, but are not 
limited to, the following risk factors and risk factors described in the 
documents incorporated herein by reference. The term "Company" refers to 
CalEnergy Company, Inc. and its operating subsidiaries, unless the context 
otherwise requires. 

   ACQUISITION UNCERTAINTIES. The Company's recent growth has been achieved, 
in part, through strategic acquisitions in the energy industry which 
complement and diversify the Company's existing business. The Company intends 
to continue to pursue an aggressive acquisition strategy for the foreseeable 
future. The Company has recently completed several major acquisitions, 
including the acquisition of Magma Power Company ("Magma"), Falcon Seaboard 
Resources, Inc. ("Falcon Seaboard") and Northern Electric plc ("Northern"). 
The Company has successfully integrated Magma, Falcon Seaboard and Northern. 
In addition, on August 11, 1998, the Company entered into an Agreement and 
Plan of Merger pursuant to which it has agreed to acquire, subject to the 
conditions set forth therein, MidAmerican Energy Holdings Company 
("MidAmerican") for approximately $2.6 billion in cash, in a transaction in 
which approximately $1.4 billion in debt and preferred stock of MidAmerican 
will remain outstanding (the "MidAmerican Merger"). See "The Company--Recent 
Developments; MidAmerican Merger." 

   Achieving the expected benefits of the MidAmerican Merger will depend in 
part upon the integration of the businesses of MidAmerican and the Company in 
an efficient manner, and despite the Company's prior experience in 
successfully integrating acquired businesses, there can be no assurance that 
this will occur. Any substantial diversion of management attention and any 
substantial difficulties encountered in the transition and integration 
process could have a material adverse effect on the revenues, levels of 
expenses and operating results of the combined company. 

   The consummation of the MidAmerican Merger is conditioned upon receipt of 
approvals of the shareholders of the Company and MidAmerican, as well as the 
Nuclear Regulatory Commission (the "NRC"), the Federal Energy Regulatory 
Commission (the "FERC"), the Iowa Utilities Board (the "IUB"), and the 
expiration or termination of the applicable waiting period under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. In 
addition, certain partial dispositions of interests in certain of the 
Company's facilities will need to be divested prior to the consummation of 
the MidAmerican Merger in order to maintain the qualifying facilities status 
of certain of the Company's independent generating facilities. There can be 
no assurance as to the timing of the required regulatory approvals, the 
ability to obtain such approvals or that such approvals will contain 
satisfactory terms and conditions. 

   The Company's ability to pursue acquisition opportunities successfully 
will depend on many factors, including, among others, the Company's ability 
to (i) identify suitable acquisition opportunities, (ii) consummate the 
acquisition, including obtaining any necessary financing, and (iii) 
successfully integrate acquired businesses. The integration of acquired 
businesses entails numerous risks, including, among others, the risk of 
diverting management's attention from the day-to-day operations of the 
Company, the risk that the acquired businesses will require substantial 
capital and financial investments and the risk that the investments will fail 
to perform in accordance with expectations. There can be no assurance that 
the MidAmerican Merger will be consummated, that additional acquisition 
opportunities, if any, can be consummated on favorable terms or that the 
Company's integration efforts will be successful. 

   HOLDING COMPANY STRUCTURE. The Company is a holding company which derives 
substantially all of its operating income from its subsidiaries and joint 
ventures. The Company expects that its future development and acquisition 
efforts will be similarly structured to involve operating subsidiaries and 
joint ventures. The Company is dependent on the earnings and cash flows of, 
and dividends from, its subsidiaries and joint ventures to generate the funds 
necessary to meet its obligations, including the 

                                4           
<PAGE>
payment of principal, interest and premium, if any, on the Debt Securities. 
The availability of distributions from such entities is subject to the 
satisfaction of various covenants and conditions contained in the applicable 
subsidiaries' and joint ventures' financing documents and to certain utility 
regulatory restrictions. Furthermore, the Company is structuring other 
project financing arrangements containing, and anticipates that future 
project level financings will contain, certain conditions and similar 
restrictions on the distribution of cash to the Company. 

   The Company's subsidiaries, partnerships and joint ventures are separate 
and distinct legal entities and have no obligation, contingent or otherwise, 
to pay any amounts due pursuant to the Debt Securities or to make any funds 
available therefor, whether by dividends, loans or other payments, and do not 
guarantee the payment of interest on, premium, if any, or principal of the 
Debt Securities. Any right of the Company to receive any assets of any of its 
subsidiaries or other affiliates upon any liquidation or reorganization of 
the Company (and the consequent right of the holders of the Debt Securities 
to participate in the distribution of, or to realize proceeds from, those 
assets) will be effectively subordinated to the claims of any such 
subsidiary's or other affiliate's creditors (including trade creditors and 
holders of debt issued by such subsidiary or other affiliate). At June 30, 
1998 the Company had approximately $6,031 million of total consolidated 
indebtedness, which included approximately $2,850 million of the Company's 
proportionate share of joint venture and subsidiary debt, which would be 
effectively senior to the Debt Securities, substantially all of which would 
have been secured by the assets of such joint ventures and subsidiaries. At 
such date, the Company also had approximately $554 million of subordinated 
debt issued in connection with Capital Trust Convertible Preferred 
Securities. 

   LEVERAGE. The Company is substantially leveraged. At June 30, 1998, the 
Company's total consolidated liabilities were approximately $6,031 million 
(excluding deferred income), its obligations in respect of the Trust 
Convertible Preferred Securities and the TIDES Securities were approximately 
$554 million, its total consolidated assets were approximately $7,482 million 
and its total stockholders' equity was approximately $780 million. The 
Company's leverage level presents the risk that the Company might not 
generate sufficient cash to service the Company's indebtedness, including the 
Debt Securities or Preferred Stock, or that its leveraged capital structure 
could limit its ability to finance future acquisitions, develop additional 
projects, compete effectively and operate successfully under adverse economic 
conditions. The Company is also a holding company which derives substantially 
all of its operating income from its subsidiaries and joint ventures. 
Distributions from such entities are restricted under various covenants and 
conditions contained in financing documents by which they are bound and the 
stock or assets of substantially all of such entities is directly or 
indirectly pledged, to secure various of such financings or such entities are 
otherwise subject to regulatory restrictions. See "Risk Factors--Holding 
Company Structure." 

   NORTHERN'S REGULATORY ENVIRONMENT. Northern's electricity distribution and 
supply business are subject to extensive regulation in the United Kingdom. 

   Price Regulation of Distribution. Revenue from Northern's distribution 
business is controlled by a formula (the "Distribution Price Control 
Formula") which determines the maximum average price per unit of electricity 
(expressed in kilowatt ("kW") hours, a "unit") that a regional electricity 
company (a "REC") in the United Kingdom may charge. The Distribution Price 
Control Formula is expected to have a five year duration and is subject to 
review by the Director General of Electricity Supply (the "Regulator") at the 
end of each five-year period and at other times in the discretion of the 
Regulator. At each review, the Regulator can propose adjustments to the 
Distribution Price Control Formula. In July 1994, a review resulted in a 17% 
reduction in allowed distribution income compared to the original formula, 
before allowing for inflation, effective April 1, 1995. In July 1995, a 
further review of distribution prices was concluded by the Regulator for 
fiscal years 1997 to 2000. As a result of this further review, Northern's 
allowed distribution from income was reduced by a further 11%, before 
allowing for inflation, effective April 1, 1996. The next review of the 
Distribution Price Control Formula is expected to occur in April 2000. There 
can be no assurance that any further price reviews by the Regulator will not 
have a material adverse effect on the Company's results of operations. 

   Competition in Supply. Northern's supply business is also subject to price 
control and is being progressively opened to competition. The market for 
customers with a maximum demand above 1 

                                5           
<PAGE>
megawatt ("MW") has been open to competition for suppliers of electricity 
since privatization while the market for customers with a maximum demand 
above 100 kW ("Non-Franchise Supply Customers") became competitive in April 
1994. The final stage of this process is expected to occur in the fall of 
1998, when the exclusive right to supply Franchise Supply Customers is 
scheduled to end. There can be no assurance that competition among suppliers 
of electricity will not have a material adverse effect on the Company's 
results of operations. The domestic gas market is also being opened to 
competition in phases and there can be no assurance that Northern will be 
successful in such competition among suppliers of gas. 

   Pool Purchase Price Volatility. Northern's supply business to 
Non-Franchise Supply Customers generally involves entering into fixed price 
contracts to supply electricity to its customers. Northern obtains the 
electricity to satisfy its obligations under such contracts primarily by 
purchases from the wholesale trading market for electricity in England and 
Wales (the "Pool"). Because the price of electricity purchased from the Pool 
can be volatile, to the extent that Northern purchases electricity from the 
Pool, Northern is exposed to risk arising from differences between the fixed 
price at which it sells and the fluctuating prices at which it purchases 
electricity, unless it can effectively hedge such exposure. Northern's 
ability to manage such risk at acceptable levels will depend, in part, on the 
specifics of the supply contracts that Northern enters into, Northern's 
ability to implement and manage an appropriate hedging strategy and the 
development of an adequate market for hedging instruments. There can be no 
assurance that this risk will be effectively mitigated. 

   Change in Government Policy. In the general election held in the United 
Kingdom on May 1, 1997, the Labour Party won a majority of seats in the 
United Kingdom Parliament. On July 31, 1997, the United Kingdom Parliament 
passed the windfall tax which was levied on privatized utilities and resulted 
in a 1997 third quarter extraordinary item of $135.85 million. See the 
Company's Current Report on Form 8-K dated July 7, 1997, incorporated herein 
by reference. There can be no assurance that other possible changes in tax or 
utility regulation by the United Kingdom government, by whichever party it is 
controlled, would not have a material adverse effect on the Company's results 
of operations. 

   DEVELOPMENT UNCERTAINTY. The Company is actively seeking to develop, 
construct, own and operate new energy projects (including, without 
limitation, generation, distribution, transmission, exploration/production, 
storage and supply projects and related activities, infrastructure and 
services), 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. Further, there can be no assurance 
that the Company, which is substantially leveraged, will obtain access to the 
substantial debt and equity capital required to continue to develop and 
construct electric power projects or to refinance projects. The future growth 
of the Company is dependent, in large part, upon the demand for significant 
amounts of additional energy (including the generation, distribution, 
transmission, exploration/ production, storage and supply projects and 
related activities, infrastructure and services) and related services and the 
Company's ability to obtain contracts to supply portions of this demand. 
There can be no assurance that development efforts on any particular project, 
or the Company's efforts generally, will be successful. 

   UNCERTAINTIES RELATED TO DOING BUSINESS OUTSIDE THE UNITED STATES. The 
Company has various projects under construction outside the United States, a 
number of projects under award outside the United States and a number of 
operating projects doing business outside of the United States. The financing 
and development of projects outside the United States entail significant 
political and financial risks (including, without limitation, uncertainties 
associated with privatization efforts in the countries involved, currency 
exchange rate fluctuations, currency repatriation restrictions, changes in 
law or regulation, changes in government policy, political instability, civil 
unrest and expropriation) and other risk/structuring issues that have the 
potential to cause substantial delays in respect of, or material 

                                6           
<PAGE>
impairment of, the value of the project being developed, constructed or 
operated, which the Company may not be capable of fully insuring against. The 
uncertainty of the legal environment in certain foreign countries in which 
the Company is developing and 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. Furthermore, the central 
bank of any such country may have the authority in certain circumstances to 
suspend, restrict or otherwise impose conditions on foreign exchange 
transactions or to approve distributions to foreign investors. Although the 
Company may structure certain power purchase agreements and other project 
revenue agreements to provide for payments to be made in, or indexed to, 
United States dollars or a currency freely convertible into United States 
dollars, there can be no assurance that the Company will be able to achieve 
this structure in all cases or that a power purchaser or other customer will 
be able to obtain sufficient dollars or other hard currency or that available 
dollars will be allocated to pay such obligations. In addition, the Company's 
investment in certain international projects, including without limitation 
Northern, where payments are to be made in the foreign currency and any 
dividends or distributions of earnings in respect of such investment may be 
significantly affected by fluctuations in the exchange rate between the 
United States dollar and the British pound or other applicable foreign 
currency. Although the Company may enter into certain transactions to hedge 
risks associated with exchange rate fluctuations, there can be no assurance 
that such transactions will be successful in reducing such risks. 

   The Company's international projects may, in certain cases, be subject to 
the risks of being delayed, suspended or terminated by the applicable foreign 
governments or may be subject to risks of contract abrogation or other 
uncertainties resulting from changes in government policy or personnel or 
changes in general political or economic conditions effecting the country. In 
this regard, reference is made to the substantial uncertainties associated 
with the Company's Indonesian projects, the contracts for which are currently 
not being honored by the Government of Indonesia and which are presently the 
subject of international arbitration. 

   EXPLORATION, DEVELOPMENT AND OPERATION UNCERTAINTIES OF GEOTHERMAL 
RESOURCES. Geothermal exploration, development and operations are subject to 
uncertainties similar to those typically associated with oil and gas 
exploration and development, including dry holes and uncontrolled releases. 
Because of the geological complexities of geothermal reservoirs, the 
geographic area and sustainable output of geothermal reservoirs can only be 
estimated and cannot be definitively established. There is, accordingly, a 
risk of an unexpected decline in the capacity of geothermal wells and a risk 
of geothermal reservoirs not being sufficient for sustained generation of the 
electrical power capacity desired. In addition, geothermal power production 
poses unusual risks of seismic activity. Accordingly, there can be no 
assurance that earthquake, property damage or business interruption insurance 
will be adequate to cover all potential losses sustained in the event of 
serious seismic disturbances or that such insurance will be available on 
commercially reasonable terms. The success of a geothermal project depends on 
the quality of the geothermal resource and operational factors relating to 
the extraction of the geothermal fluids involved in such project. The quality 
of a geothermal resource is affected by a number of factors, including the 
size of the reservoir, the temperature and pressure of the geothermal fluids 
in such reservoir, the depth and capacity of the production and injection 
wells, the amount of dissolved solids and noncondensible gases contained in 
such geothermal fluids, and the permeability of the subsurface rock 
formations containing such geothermal resource, including the presence, 
extent and location of fractures in such rocks. The quality of a geothermal 
resource may decline as a result of a number of factors, including the 
intrusion of lower-temperature fluid into the producing zone. An incorrect 
estimate by the Company of the quality of a geothermal resource, or a decline 
in such quality, could have a material adverse effect on the Company's 
results of operations. In addition, both the cost of operations and the 
operating performance of geothermal power plants may be adversely affected by 
a variety of resource operating factors. Production and injection wells can 
require frequent maintenance or replacement. Corrosion caused by 
high-temperature and high-salinity geothermal fluids may compel the 
replacement or repair of certain equipment, vessels or pipelines. New 
production and injection wells may be required for the maintenance of 
operating levels, thereby requiring substantial capital expenditures. 

                                7           
<PAGE>
   EXPLORATION, DEVELOPMENT AND PRODUCTION OF GAS RESOURCES. The exploration 
development and production of gas resources involve resource based and 
geologic risks similar to those for geothermal resources described above, 
including dry holes, uncontrolled releases and uncertainties relating to 
resource production, required capital and operating expenditures, and 
resource quality, quantity, extractability, sustainability and extent of 
reserves. 

   GENERAL OPERATING UNCERTAINTIES. The operation of a power plant involves 
many risks, including the breakdown or failure of power generation equipment, 
pipelines, transmission lines or other equipment or processes, fuel 
interruption, and performance below expected levels of output or efficiency. 
Each facility may depend on a single or limited number of entities to 
purchase electricity or thermal energy, to supply water, to supply gas, to 
transport gas, to dispose of wastes or to wheel electricity. The failure of 
any such purchasing utility, steam host, water or gas supplier, gas 
transporter, wheeling utility or other relevant project participant to 
fulfill its contractual obligations could have a material adverse impact on 
the Company. 

   FUEL SUPPLY OPERATIONS. The primary fuel source for certain of the 
Company's projects is natural gas and a substantial portion of the operating 
expenses of such facilities consists of the costs of obtaining natural gas 
through gas supply agreements and transporting that gas to the projects under 
gas transportation agreements. Although the Company believes that it has 
contracted for natural gas supply and transportation in sufficient quantities 
to satisfy the needs of its projects, the gas suppliers are not required in 
all cases to provide dedicated reserves in support of their contractual 
obligations. Unless the gas projects were able to obtain substitute volumes 
of natural gas including the requisite transportation services, for such 
volumes at a price not materially higher than the sum of the contract price 
under the existing gas supply agreements and any damages paid by the supplier 
for failure to deliver, the sustained failure of a supplier to deliver 
natural gas in accordance with its contract could have a material adverse 
effect on the cash flows to the Company. In addition, under certain gas 
supply contracts the Company is obligated to pay for a certain minimum 
quantity of natural gas even if it cannot utilize it. The Company intends to 
manage its requirements for contract volumes under the gas supply agreements 
so as to meet the minimum take requirements through a combination of 
utilization of nominated volumes in operations and resales of the remainder 
of the volumes to third-party customers, if necessary. Finally, the state, 
federal and Canadian regulatory authorities that have jurisdiction over 
natural gas transportation have the right to modify aspects of the rates, 
terms and conditions of those contracts. It is possible that such a 
modification could materially increase the fuel transportation costs of the 
projects or give the transporter a right to terminate or suspend or decrease 
its performance under its contract. 

   PRESENT DEPENDENCE ON LARGE CUSTOMER; CONTRACT UNCERTAINTIES. The Company 
currently relies on long-term power purchase "Standard Offer No. 4" contracts 
(each, an "SO4 Agreement") with a large customer, Southern California Edison 
Company ("Edison"), to generate a substantial portion of its operating 
revenues. Any material failure by Edison to fulfill its contractual 
obligations under such contracts is likely to have a material adverse effect 
on the Company's results of operations. Each of the Company's SO4 Agreements 
provides for both capacity payments and energy payments for a term of between 
20 and 30 years. During the first ten years after achieving firm operation, 
energy payments under each SO4 Agreement are based on a pre-set schedule. 
Thereafter, while the basis for the capacity payment remains the same, the 
required energy payment is Edison's then-current published avoided cost of 
energy ("Avoided Cost of Energy") as determined by the California Public 
Utility Commission ("CPUC"). The initial ten-year period expired in August 
1997 for the Company's Navy I Project and will expire in March 1999 for its 
BLM Project and January 2000 for its Navy II Project, which three projects 
comprise the Coso Project in California (the "Coso Project"). Such ten-year 
period expired in 1996 with respect to one of the eight geothermal plants in 
the Imperial Valley in California ("Imperial Valley Projects") and expires in 
1999 for three of its Imperial Valley Projects and in 2000 for the remaining 
two Imperial Valley Projects that operate under SO4 Agreements. 

   Estimates of Edison's future Avoided Cost of Energy vary substantially in 
any given year. The Company cannot predict the likely level of Avoided Cost 
of Energy prices under its SO4 Agreements with Edison at the expiration of 
the fixed-price periods. Edison's Avoided Cost of Energy as determined by the 
CPUC is currently substantially below the current scheduled energy prices 
under the Company's 

                                8           
<PAGE>
respective SO4 Agreements and is currently expected to remain so. For the 
year ended December 31, 1997, the time period-weighted average of Edison's 
Avoided Cost of Energy was 3.3 cents per kWh, compared to the time 
period-weighted average for the year ended December 31, 1997 selling prices 
for energy of approximately 12.0 cents per kWh for the Company's SO4 
Agreements. Thus, the revenues generated by each of the Company's facilities 
operating under SO4 Agreements are likely to decline significantly after the 
expiration of the applicable fixed price period. Moreover, the Company's 
subsidiaries have a number of ongoing contract disputes with Edison involving 
litigation of the SO4 Agreements, which create additional litigation 
uncertainties regarding such contracts. 

   COMPETITION AND DOMESTIC DEREGULATION; INDUSTRY RESTRUCTURING. The 
international power production market is characterized by numerous strong and 
capable competitors, many of which have more extensive and more diversified 
developmental or operating experience (including international experience) 
and greater financial resources than the Company. Many of these competitors 
also compete in the domestic market. Further, in recent years, the domestic 
power production industry has been characterized by strong and increasing 
competition with respect to the industry's efforts to obtain new power sales 
agreements, which has contributed to a reduction in prices offered to 
utilities. In that regard, many utilities often engage in "competitive bid" 
solicitations to satisfy new capacity demands. In the domestic market, 
competition is expected to increase as the electric utility industry becomes 
deregulated. In addition, recent deregulation and industry restructuring 
activity may cause certain utilities or other contract parties to attempt to 
renegotiate contracts or otherwise fail to perform their contractual 
obligations, which in turn could adversely affect the Company's results of 
operations. In particular, the state of California has restructured its 
electric industry by providing for a phased-in competitive power generation 
industry, with a power pool and an independent system operator, and for 
direct access to generation for all power purchasers outside the power 
exchange under certain circumstances. Although existing qualifying facility 
power sales contracts are to be honored under such restructuring, and all of 
the Company's California operating projects are qualifying facilities, until 
the new system is fully implemented, it is impossible to predict what impact, 
if any, it may have on the operations of those projects. In addition, if the 
MidAmerican Merger is consummated, future industry restructuring efforts by 
states in the Midwest (such as Iowa or Illinois) where MidAmerican has 
substantial operations could impact the results of operations of MidAmerican 
in a manner which is difficult to predict, since such effects will depend on 
the form and timing of such restructuring. 

   IMPACT OF ENVIRONMENTAL, ENERGY AND OTHER REGULATIONS. The Company is 
subject to a number of environmental and other laws and regulations affecting 
many aspects of its present and future operations, including the disposal of 
various forms of waste, the construction or permitting of new facilities, and 
the drilling and operation of new and existing wells. Such laws and 
regulations generally require the Company to obtain and comply with a wide 
variety of licenses, permits and other approvals. The Company also remains 
subject to a number of complex and stringent laws and regulations that both 
public officials and private individuals may seek to enforce. There can be no 
assurance that existing regulations will not be revised or that new 
regulations will not be adopted or become applicable to the Company which 
could have an adverse impact on its operations. The implementation of 
regulatory changes imposing more comprehensive or stringent requirements on 
the Company, which would result in increased compliance costs, could have a 
material adverse effect on the Company's results of operations. Without 
limiting the generality of the foregoing, if the MidAmerican Merger is 
consummated, regulatory requirements applicable in the future to coal or 
nuclear generating facilities could adversely affect the results of 
operations of MidAmerican. In addition, regulatory compliance for the 
construction of new facilities is a costly and time-consuming process, and 
intricate and rapidly changing environmental regulations may require major 
expenditures for permitting and create the risk of expensive delays or 
material impairment of project value if projects cannot function as planned 
due to changing regulatory requirements or local opposition. 

   The Public Utility Regulatory Policies Act of 1978, as amended ("PURPA"), 
and the Public Utility Holding Company Act of 1935, as amended ("PUHCA"), are 
two of the laws (including the regulations thereunder) that affect the 
Company's operations. PURPA provides to qualifying facilities ("QFs") certain 
exemptions from federal and state laws and regulations, including 
organizational, rate and 

                                9           
<PAGE>
financial regulation. PUHCA regulates public utility holding companies and 
their subsidiaries. The Company is not and will not be subject to regulation 
as a holding company under PUHCA as long as the domestic power plants it owns 
are QFs under PURPA or are exempted as exempt wholesale generators ("EWGs"), 
and so long as its foreign utility operations are exempted as EWGs or foreign 
utility companies or are otherwise exempted under PUHCA. QF status is 
conditioned on meeting certain criteria, and would be jeopardized, for 
example, in the case of the Company's cogeneration facilities, by the loss of 
a steam customer or reduction of steam purchases below the amount required by 
PURPA. The Company's four cogeneration facilities have steam sales agreements 
with existing industrial hosts which agreements must be maintained in effect 
or replaced in order to maintain QF status. In the event the Company were 
unable to avoid the loss of such status for one of its facilities, such an 
event could result in termination of a given project's power sales agreement 
and a default under the project subsidiary's project financing agreements. 

   Currently, Congress is considering proposed legislation that would amend 
PURPA by eliminating the requirement that utilities purchase electricity from 
qualifying facilities at prices based on Avoided Costs of Energy. The Company 
does not know whether such legislation will be passed or what form it may 
take. The Company believes that if any such legislation is passed, it would 
apply to new projects only and thus, although potentially impacting the 
Company's ability to develop new domestic projects, it would not affect the 
Company's existing qualifying facilities. There can be no assurance, however, 
that any legislation passed would not adversely impact the Company's existing 
domestic projects. 

   In addition, many states are implementing or considering regulatory 
initiatives designed to increase competition in the domestic power generation 
industry and increase access to electric utilities' transmission and 
distribution systems for independent power producers and electricity 
consumers. As noted above, if the MidAmerican Merger is consummated, industry 
restructuring efforts by states in the Midwest (such as Iowa and Illinois) 
where MidAmerican has substantial operations could affect MidAmerican's 
operations in a manner which is difficult to predict, since such effects will 
depend on the form and timing of such restructuring. The structure of such 
federal and state energy regulations have in the past, and may in the future, 
be the subject of various challenges and restructuring proposals by utilities 
and other industry participants. The implementation of regulatory changes in 
response to such changes or restructuring proposals, or otherwise imposing 
more comprehensive or stringent requirements on the Company, which would 
result in increased compliance costs, could have a material adverse effect on 
the Company's results of operations. 

   SHARES OF COMMON STOCK ELIGIBLE FOR FUTURE SALE. Pursuant to the Company's 
1996 Stock Option Plan (the "1996 Plan"), as of June 30, 1998, the Company 
had outstanding various options to its officers, directors and employees for 
the purchase of 5,694,745 shares of Common Stock. All of the shares of Common 
Stock issuable upon exercise of said options have been registered pursuant to 
registration statements on Form S-8, and, when fully vested and exercised, 
are available for immediate resale. Sales of substantial amounts of Common 
Stock or the availability of Common Stock for sale, could have an adverse 
impact on the market price of the Common Stock and on the Company's ability 
to raise additional capital through the sale of Common Stock. 

   LACK OF PUBLIC MARKET FOR THE DEBT SECURITIES AND THE PREFERRED 
STOCK. There is no existing public trading market for the Debt Securities and 
the Preferred Stock and there can be no assurance regarding the future 
development of a market for either the Debt Securities or the Preferred 
Stock, or the ability of holders of such securities to sell their Debt 
Securities and/or Preferred Stock or the price at which such holders may be 
able to sell their Securities. If such a market were to develop, the Debt 
Securities and/or Preferred Stock could trade at prices that may be higher or 
lower than their initial offering price depending on many factors, including 
prevailing interest rates, the price of Common Stock, the Company's operating 
results and the market for similar securities. Historically, the market for 
non-investment grade debt has demonstrated substantial volatility in the 
prices of securities similar to the Debt Securities. There can be no 
assurance that the future market for the Debt Securities will not be subject 
to similar volatility.

generation facilities in operation, construction and development worldwide 
and currently operates 20 generating facilities. In addition, through its 
subsidiary, Northern Electric plc ("Northern"), the Company is engaged in the 
distribution and supply of electricity and gas to approximately 1.9 million 
customers in the U.K. The Company employs 4,200 people worldwide. For the

RECENT DEVELOPMENTS; MIDAMERICAN MERGER 

   On August 11, 1998, the Company announced that it had entered into an 
Agreement and Plan of Merger with MidAmerican Energy Holdings Company 
("MidAmerican"), pursuant to which the Company agreed (i) to pay $27.15 in 
cash for each outstanding share of MidAmerican common stock for an aggregate 
purchase price of approximately $2.65 billion, in a transaction in which 
approximately $1.4 billion of debt and preferred securities of MidAmerican 
will remain outstanding, in a merger pursuant to which MidAmerican will 
become a wholly owned subsidiary of the Company, and (ii) to reincorporate in 
the State of Iowa and be renamed MidAmerican Energy Holdings Company. Closing 
of the transaction is subject to the approval of the shareholders of both 
companies and the obtaining of certain regulatory approvals. The transaction 
is presently expected to close by the end of the first quarter of 1999. See 
"Risk Factors--Acquisition Uncertainties; MidAmerican Merger." Reference is 
also made to the Company's Current Report on Form 8-K dated August 12, 1998 
which contains the Merger Agreement relating to the MidAmerican Merger, which 
Form 8-K is incorporated herein by reference.

                      RATIO OF EARNINGS TO FIXED CHARGES 

   The following table sets forth the Company's ratio of earnings to fixed 
charges on a historical basis for each of the five years in the period ended 
December 31, 1997 and for the six months ended June 30, 1997 and 1998.

- ------------ 
(1)     The ratio of earnings to fixed charges for the year ended December 
        31, 1997 was impacted by the $87 million non-recurring asset 
        impairment charge related to the Company's assets in Indonesia. 
        Without this charge, the ratio of earnings to fixed charges would 
        have been 1.7. 

   For purposes of computing historical ratios of earnings to fixed charges, 
earnings are divided by fixed charges. "Earnings" represent the aggregate of 
(a) the pre-tax income of the Company, including its proportionate share of 
the pre-tax income of the Coso Project and excluding the equity in loss of a 
non-consolidated subsidiary, and (b) fixed charges, less capitalized 
interest. "Fixed charges" represent interest (whether expensed or 
capitalized), amortization of deferred financing and bank fees, and the 
portion of rentals considered to be representative of the interest factor 
(one-third of lease payments) and preferred stock dividend requirements of 
majority owned subsidiaries. 

                               USE OF PROCEEDS 

   Unless otherwise set forth in the applicable Prospectus Supplement 
accompanying this Prospectus, proceeds from the sale of the Offered 
Securities ultimately will be used by the Company to make equity investments 
in future domestic and international energy projects, to fund possible 
project or Company acquisitions, for the repayment of debt or for other 
general corporate purposes, and initially may be temporarily invested in 
short-term securities. See "The Company--Recent Developments; MidAmerican 
Merger."

                         DESCRIPTION OF CAPITAL STOCK 

   The following summary does not purport to be complete and is subject to, 
and qualified in its entirety by, the Company's Restated Certificate of 
Incorporation, as amended (the "Restated Certificate of Incorporation"), and 
the Company's By-Laws, as amended (the "By-Laws"), and by the provisions of 
applicable law. The authorized capital stock of the Company consists of 
180,000,000 shares of Common Stock, par value $0.0675 per share, and 
2,000,000 shares of Preferred Stock, no par value. This summary contains a 
description of certain general terms of the Common Stock and the Preferred 
Stock to which any Prospectus Supplement may relate. Certain terms of any 
Common Stock or any series of Preferred Stock offered by a Prospectus 
Supplement will be described in the Prospectus Supplement relating thereto, 
including the number of shares, offered, any initial offering price, and 
market price and dividend information. If so indicated in the Prospectus 
Supplement, the terms of any series may differ from the terms set forth 
below. 

COMMON STOCK 

   At June 30, 1998, there were 60,032,677 shares of Common Stock 
outstanding. The holders of Common Stock are entitled to one vote for each 
share held of record on all matters submitted to a vote of stockholders. 
Holders of the Common Stock vote together as a single class on all matters. 
Subject to preferences that may be applicable to any outstanding Preferred 
Stock, holders of Common Stock are entitled to receive ratably such dividends 
as may be declared by the Board of Directors out of funds legally available 
therefor. In the event of a liquidation, dissolution or winding up of the 
Company, holders of Common Stock are entitled to share ratably in all assets 
remaining after payment of liabilities and the liquidation preference of any 
outstanding Preferred Stock. The outstanding shares of Common Stock are fully 
paid and nonassessable. The Common Stock will, when issued against payment 
therefor, be fully paid and nonassessable. 

   On December 1, 1988, the Company distributed a dividend of one Preferred 
Share Purchase Right (a "Right") for each outstanding share of Common Stock. 
The Rights are not exercisable until ten days after a person or group, 
without prior Board approval, acquires, or has the right to acquire, 
beneficial ownership of 20% or more of the Common Stock or announces a tender 
or exchange offer for 30% or more of the Common Stock. Each Right entitles 
the holder to purchase one one-hundredth of a share of Series A Junior 
Preferred Stock, no par value ("Series A Preferred Stock"), for $52. The 
Rights may be redeemed by the Board of Directors up to ten days after an 
event triggering the distribution of certificates for the Rights. The Rights 
are automatically attached to, and trade with, each share of Common Stock. 
The Rights will expire, unless previously redeemed or exercised, on November 
30, 1998. 

PREFERRED STOCK 

   The Board of Directors has the authority to issue up to 2,000,000 shares 
of Preferred Stock in one or more series and to fix the rights, preferences, 
privileges and restrictions thereof, including dividend rights, dividend 
rates, conversion rights, voting rights, terms of redemption, redemption 
prices, liquidation preferences and the number of shares constituting any 
series or the designation of such series, without any further action by the 
stockholders. The issuance of shares of Preferred Stock may have the effect 
of delaying, deferring or preventing a change in control of the Company 
without further action by the stockholders. The issuance of shares of 
Preferred Stock with voting and conversion rights may adversely affect the 
voting power of the holders of Common Stock, including the loss of voting 
control to others. The Company has no present plans to issue any additional 
shares of Preferred Stock. See "Description of Preferred Stock." 

RESTATED CERTIFICATE OF INCORPORATION AND BY-LAW PROVISIONS AFFECTING CHANGE 
IN CONTROL 

   The Restated Certificate of Incorporation and the By-Laws include certain 
provisions that are intended to enhance the likelihood of continuity and 
stability in the composition of the Board of Directors and that may have the 
effect of delaying, deterring or preventing a future takeover or change in 
control of the Company, unless such takeover or change in control is approved 
by the Board of Directors. Such provisions may also render the removal of the 
directors and management more difficult. Such provisions 

                               13           
<PAGE>
include a classified Board of Directors divided into three classes serving 
staggered three-year terms, prohibit stockholders of the Company from taking 
action by written consent, require the affirmative vote of at least 66 2/3% 
of the outstanding shares of stock of the Company entitled to vote thereon to 
adopt, repeal, alter, amend or rescind the By-Laws, and require that special 
meetings of stockholders be called only by the Board of Directors or the 
Chief Executive Officer. In addition to the foregoing, the Board of Directors 
has adopted a Stockholder Rights Plan, which provided for a dividend of one 
Right for each outstanding share of Common Stock. See "--Common Stock." 

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW 

   The Company is subject to the provisions of Section 203 of the Delaware 
General Corporation Law ("Section 203"). Under Section 203, certain "business 
combinations" between a Delaware corporation whose stock is publicly traded 
or held of record by more than 2,000 stockholders and an "interested 
stockholder" are prohibited for a three-year period following the date that 
such stockholder became an interested stockholder, unless (i) the corporation 
has elected in its original certificate of incorporation not to be governed 
by Section 203 (the Company did not make such an election), (ii) the 
transaction in which the stockholder became an interested stockholder or the 
business combination was approved by the board of directors of the 
corporation before the other party to the business combination became an 
interested stockholder, (iii) upon consummation of the transaction that made 
it an interested stockholder, the interested stockholder owned at least 85% 
of the voting stock of the corporation outstanding at the commencement of the 
transaction (excluding voting stock owned by directors who are also officers 
or held in employee benefit plans in which the employees do not have a 
confidential right to tender or vote stock held by the plan) or (iv) the 
business combination was approved by the board of directors of the 
corporation and ratified by two-thirds of the voting stock which the 
interested stockholder did not own. The term "business combination" is 
defined generally to include mergers or consolidations between a Delaware 
corporation and an "interested stockholder," transactions with an "interested 
stockholder" involving the assets or stock of the corporation or its 
majority-owned subsidiaries and transactions which increase an "interested 
stockholder's" percentage ownership of stock. The term "interested 
stockholder" is defined generally as a stockholder who, together with its 
affiliates and associates, owns (or, within three years prior, did own) 15% 
or more of a Delaware corporation's voting stock. Section 203 could prohibit 
or delay a merger, takeover or other change in control of the Company and 
therefore could discourage attempts to acquire the Company.

                        DESCRIPTION OF PREFERRED STOCK 

   The following description of the terms of the shares of Preferred Stock 
that may be offered by the Company sets forth certain general terms and 
provisions of the Preferred Stock to which any Prospectus Supplement may 
relate. Certain other terms of any series of Preferred Stock and the terms of 
any related option, put or right of the Company to require the holder of any 
other Security offered to also acquire shares of Preferred Stock will be 
specified in the applicable Prospectus Supplement. If so specified in the 
applicable Prospectus Supplement, the terms of any series of Preferred Stock 
may differ from the terms set forth below. The description of the terms of 
the Preferred Stock set forth below and in any Prospectus Supplement is 
necessarily a summary thereof and is qualified in its entirety by reference 
to the Certificate of Designation relating to the applicable series of 
Preferred Stock, which Certificate of Designation will be filed as an exhibit 
to or incorporated by reference in the Registration Statement of which this 
Prospectus forms a part. 

GENERAL 

   Pursuant to the Restated Certificate of Incorporation and the Delaware 
General Corporation Law, the Board of Directors of the Company has the 
authority, without further stockholder action, to issue from time to time up 
to a maximum of up to 2,000,000 shares of Preferred Stock, in one or more 
series and for such consideration as may be fixed from time to time by the 
Board of Directors of the Company and to fix before the issuance of any 
shares of Preferred Stock of a particular series, the designation of such 
series, the number of shares to comprise such series, the dividend rate or 
rates payable with respect to the shares of such series, the redemption price 
or prices, if any, and the terms and conditions of any redemption, the voting 
rights, any sinking fund provisions for the redemption or purchase of the 
shares of such series, the terms and conditions upon which the shares are 
convertible or exchangeable, if they are convertible or exchangeable, and any 
other relative rights, preferences and limitations pertaining to such series. 

   Reference is made to the Prospectus Supplement relating to the particular 
series of Preferred Stock offered thereby for specific terms, including: (i) 
the designation, stated value and liquidation preference of such Preferred 
Stock and the number of shares offered; (ii) the initial public offering 
price at which such shares will be issued; (iii) the dividend rate or rates 
(or method of calculation), the dividend periods, the date or dates on which 
dividends shall be payable and whether such dividends shall be cumulative or 
noncumulative and, if cumulative, the dates from which dividends shall 
commence to cumulate; (iv) any redemption or sinking fund provisions; (v) any 
conversion or exchange provisions; (vi) the procedures for any auction and 
remarketing, if any, of such Preferred Stock; (vii) whether interests in 
Preferred Stock will be represented by depositary shares; and (viii) any 
additional dividend, liquidation, redemption, sinking fund and other rights, 
preferences, privileges, limitations and restrictions of such Preferred 
Stock. 

   The Preferred Stock will, when issued against payment therefor, be fully 
paid and nonassessable. Holders of Preferred Stock will have no preemptive 
rights to subscribe for any additional securities which may be issued by the 
Company. 

   Because the Company is a holding company, its rights and the rights of 
holders of its securities, including the holders of Preferred Stock, to 
participate in the distribution of assets of any subsidiary of the Company 
upon the latter's liquidation or recapitalization will be subject to the 
prior claims of such subsidiary's creditors and preferred stockholders, 
except to the extent the Company may itself be a creditor with recognized 
claims against such subsidiary or a holder of preferred stock of such 
subsidiary. 

DIVIDENDS 

   The holders of the Preferred Stock will be entitled to receive, when and 
as declared by the Board of Directors of the Company, out of funds legally 
available therefor, dividends at such rates and on such dates as will be 
specified in the applicable Prospectus Supplement. Such rates may be fixed or 
variable or both. If variable, the formula used for determining the dividend 
rate for each dividend period will be specified in the applicable Prospectus 
Supplement. Dividends will be payable to the holders of record as they appear 
on the stock books of the Company on such record dates as will be fixed by 
the Board of 

                               15           
<PAGE>
Directors of the Company. Dividends may be paid in the form of cash, 
Preferred Stock (of the same or a different series) or Common Stock of the 
Company, in each case as specified in the applicable Prospectus Supplement. 

   Dividends on any series of Preferred Stock may be cumulative or 
noncumulative, as specified in the applicable Prospectus Supplement. 
Dividends, if cumulative, will be cumulative from and after the date set 
forth in the applicable Prospectus Supplement. If the Board of Directors of 
the Company fails to declare a dividend payable on a dividend payment date on 
any Preferred Stock for which dividends are noncumulative ("Noncumulative 
Preferred Stock"), then the holders of such Preferred Stock will have no 
right to receive a dividend in respect of the dividend period relating to 
such dividend payment date, and the Company will have no obligation to pay 
the dividend accrued for such period, whether or not dividends on such 
Preferred Stock are declared or paid on any future dividend payment dates. 

   The Company shall not declare, pay or set apart for payment any dividends 
on any series of its Preferred Stock ranking, as to dividends, on a parity 
with or junior to the outstanding Preferred Stock of any series unless (i) if 
such series of Preferred Stock has a cumulative dividend ("Cumulative 
Preferred Stock"), full cumulative dividends have been or contemporaneously 
are declared and paid or declared and a sum sufficient for the payment 
thereof set apart for such payment on such Preferred Stock for all past 
dividend periods and the then current dividend period, or (ii) if such series 
of Preferred Stock is Noncumulative Preferred Stock, full dividends for the 
then current dividend period on such Preferred Stock have been or 
contemporaneously are declared and paid or declared and a sum sufficient for 
the payment thereof set apart for such payment. When dividends are not paid 
in full upon Preferred Stock of any series and any other shares of Preferred 
Stock of the Company ranking on a parity as to dividends with such Preferred 
Stock, all dividends declared upon such Preferred Stock and any other 
Preferred Stock of the Company ranking on a parity as to dividends with such 
Preferred Stock shall be declared pro rata so that the amount of dividends 
declared per share on such Preferred Stock and such other shares of Preferred 
Stock shall in all cases bear to each other the same ratio that the accrued 
dividends per share on such Preferred Stock (which shall not, if such 
Preferred Stock is Noncumulative Preferred Stock, include any accumulation in 
respect of unpaid dividends for prior dividend periods) and such other shares 
of Preferred Stock bear to each other. No interest, or sum of money in lieu 
of interest, shall be payable in respect of any dividend payment or payments 
on Preferred Stock of such series which may be in arrears. 

   Except as set forth in the preceding sentence, unless (i) full dividends 
on the outstanding Cumulative Preferred Stock of any series have been or 
contemporaneously are declared and paid or declared and a sum sufficient for 
the payment thereof set apart for payment for all past dividend periods and 
the then current dividend period or (ii) full dividends for the then current 
dividend period on the outstanding Noncumulative Preferred Stock of any 
series have been or contemporaneously are declared and paid or declared and a 
sum sufficient for the payment thereof set apart for such payment, no 
dividends (other than in Common Stock of the Company or other shares of the 
Company ranking junior to such Preferred Stock as to dividends and upon 
liquidation) shall be declared or paid or set aside for payment, nor shall 
any other distribution be made, on the Common Stock of the Company or on any 
other shares of the Company ranking junior to or on a parity with such 
Preferred Stock as to dividends or upon liquidation. 

   Unless (i) full dividends on the Cumulative Preferred Stock of any series 
have been or contemporaneously are declared and paid or declared and a sum 
sufficient for the payment thereof set apart for payment for all past 
dividend periods and the then current dividend period or (ii) full dividends 
for the then current dividend period on the Noncumulative Preferred Stock of 
any series have been declared and paid or declared and a sum sufficient for 
the payment thereof set apart for such payment, no Common Stock or any other 
shares of the Company ranking junior to or on a parity with such Preferred 
Stock as to dividends or upon liquidation shall be redeemed, purchased or 
otherwise acquired for any consideration (or any moneys be paid or made 
available for a sinking fund for the redemption of any such shares) by the 
Company or any subsidiary of the Company except by conversion into or 
exchange for shares of the Company ranking junior to such Preferred Stock as 
to dividends and upon liquidation. Any dividend payment made on shares of 
Cumulative Preferred Stock of any series shall first be credited against the 
earliest accrued but unpaid dividend due with respect to shares of such 
series which remains unpaid. 

                               16           
<PAGE>
REDEMPTION 

   Preferred Stock may be redeemable, in whole or in part, at the option of 
the Company, out of funds legally available therefor, and may be subject to 
mandatory redemption pursuant to a sinking fund or otherwise, in each case 
upon terms, at the times and at the redemption prices specified, in the 
applicable Prospectus Supplement. Preferred Stock redeemed by the Company 
will be restored to the status of authorized but unissued shares of Preferred 
Stock. 

   The Prospectus Supplement relating to a series of Preferred Stock that is 
subject to mandatory redemption will specify the number of shares of such 
Preferred Stock that shall be redeemed by the Company in each year commencing 
after a date to be specified, at a redemption price per share to be 
specified, together with an amount equal to all accrued and unpaid dividends 
thereon (which shall not, if such Preferred Stock is Noncumulative Preferred 
Stock, include any accumulation in respect of unpaid dividends for prior 
dividend periods) to the date of redemption. The redemption price may be 
payable in cash or other property, as specified in the applicable Prospectus 
Supplement. If the redemption price for Preferred Stock of any series is 
payable only from the net proceeds of the issuance of capital stock of the 
Company, the terms of such Preferred Stock may provide that, if no such 
capital stock shall have been issued or to the extent the net proceeds from 
any issuance are insufficient to pay in full the aggregate redemption price 
then due, such Preferred Stock shall automatically and mandatorily be 
converted into shares of the applicable capital stock of the Company pursuant 
to conversion provisions specified in the applicable Prospectus Supplement. 

   Notwithstanding the foregoing, unless (i) full dividends on the Cumulative 
Preferred Stock of any series have been or contemporaneously are declared and 
paid or declared and a sum sufficient for the payment thereof set apart for 
payment for all past dividend periods and the then current dividend period or 
(ii) full dividends for the then current dividend period on the Noncumulative 
Preferred Stock of any series have been or contemporaneously are declared and 
paid or declared and a sum sufficient for the payment thereof set apart for 
payment, no shares of Preferred Stock of such series shall be redeemed unless 
all outstanding shares of Preferred Stock of such series are simultaneously 
redeemed, and the Company shall not purchase or otherwise acquire any shares 
of Preferred Stock of such series; provided, however, that the foregoing 
shall not prevent the purchase or acquisition of Preferred Stock of such 
series pursuant to a purchase or exchange offer provided such offer is made 
on the same terms to all holders of the Preferred Stock of such series. 

   Notice of redemption shall be given by mailing the same to each record 
holder of the Preferred Stock to be redeemed, not less than 30 nor more than 
60 days prior to the date fixed for redemption thereof, at the address of 
such holder as the same shall appear on the stock books of the Company. Each 
notice shall state: (i) the redemption date; (ii) the number of shares and 
series of the Preferred Stock to be redeemed; (iii) the redemption price; 
(iv) the place or places where certificates for such Preferred Stock are to 
be surrendered for payment of the redemption price; (v) that dividends on the 
shares to be redeemed will cease to accrue on such redemption date; and (vi) 
the date upon which the holder's conversion or exchange rights, if any, as to 
such shares shall terminate. If fewer than all the shares of Preferred Stock 
of any series are to be redeemed, the notice mailed to each such holder 
thereof shall also specify the number of shares of Preferred Stock to be 
redeemed from each such holder. 

   If fewer than all the outstanding shares of Preferred Stock of any series 
are to be redeemed, the number of shares to be redeemed will be determined by 
the Board of Directors of the Company and such shares may be redeemed pro 
rata from the holders of record of such shares in proportion to the number of 
such shares held by such holders (with adjustments to avoid redemption of 
fractional shares) or by lot in a manner determined by the Board of Directors 
of the Company. 

   If notice of redemption of any shares of Preferred Stock has been given 
and if the funds necessary for such redemption have been set aside by the 
Company, separate and apart from its other funds, in trust for the pro rata 
benefit of holders of any shares of Preferred Stock so called for redemption, 
then from and after the redemption date for such shares, dividends on such 
shares shall cease to accrue and such shares shall no longer be deemed to be 
outstanding, and all rights of the holders thereof as stockholders of the 
Company (except the right to receive the redemption price) shall cease. Upon 
surrender, in 

                               17           
<PAGE>
accordance with such notice, of the certificates representing any such shares 
(properly endorsed or assigned for transfer, if the Board of Directors of the 
Company shall so require and the notice shall so state), the redemption price 
set forth above shall be paid out of the funds provided by the Company. If 
fewer than all the shares represented by any such certificate are redeemed, a 
new certificate shall be issued representing the unredeemed shares without 
cost to the holder thereof. 

CONVERSION OR EXCHANGE RIGHTS 

   The Prospectus Supplement relating to a series of Preferred Stock that is 
convertible or exchangeable will state the terms on which shares of such 
series are convertible or exchangeable into Common Stock, another series of 
Preferred Stock or Debt Securities. 

RIGHTS UPON LIQUIDATION 

   In the event of any voluntary or involuntary liquidation, dissolution or 
winding up of the Company, the holders of each series of Preferred Stock 
shall be entitled to receive out of the assets of the Company legally 
available for distribution to stockholders, before any distribution of assets 
is made to holders of Common Stock or any other class or series of capital 
stock ranking junior to such Preferred Stock upon liquidation, liquidating 
distributions in the amount of the liquidation preference of such Preferred 
Stock plus all accrued and unpaid dividends thereon (which shall not, in the 
case of Noncumulative Preferred Stock, include any accumulation in respect of 
unpaid dividends for prior dividend periods). If, upon any voluntary or 
involuntary liquidation, dissolution or winding up of the Company, the 
amounts payable with respect to Preferred Stock of any series and any other 
shares of Preferred Stock of the Company ranking as to any such distribution 
on a parity with such Preferred Stock are not paid in full, the holders of 
such Preferred Stock and of such other shares of Preferred Stock will share 
ratably in any such distribution of assets of the Company in proportion to 
the full respective preferential amounts to which they are entitled. After 
payment of the full amount of the liquidating distribution to which they are 
entitled, the holders of Preferred Stock of any series Will not be entitled 
to any further participation in any distribution of assets by the Company. 

VOTING RIGHTS 

   Except as indicated below or in the applicable Prospectus Supplement, or 
except as expressly required by applicable law, the holders of Preferred 
Stock will not be entitled to vote. 

   If the Company fails to pay dividends on any shares of Preferred Stock for 
six consecutive quarterly periods, the holders of such shares of Preferred 
Stock (voting separately as a class with all other series of Preferred Stock 
upon which like voting rights have been conferred and are exercisable) will 
be entitled to vote for the election of two additional directors of the 
Company at a special meeting called by the holders of record of at least 10% 
of such Preferred Stock or the next annual meeting of stockholders and at 
each subsequent meeting until (i) all dividends accumulated on shares of 
Cumulative Preferred Stock for the past dividend periods and the then current 
dividend period shall have been fully paid or declared and a sum sufficient 
for the payment thereof set aside for payment or (ii) four consecutive 
quarterly dividends on shares of Noncumulative Preferred Stock shall have 
been fully paid or declared and a sum sufficient for the payment thereof set 
aside for payment. In such case, the entire Board of Directors of the Company 
will be increased by two directors. 

   So long as any shares of Preferred Stock remain outstanding, the Company 
shall not, without the affirmative vote of the holders of at least two-thirds 
of each series of Preferred Stock outstanding at the time, given in person or 
by proxy, at a meeting (voting separately as a class): (i) authorize, create 
or issue, or increase the authorized or issued amount of, any class or series 
of capital stock ranking prior to such series of Preferred Stock with respect 
to payment of dividends or distribution of assets upon liquidation, 
dissolution or winding up, or reclassify any capital stock into any such 
shares, or authorize, create or issue any obligation or security convertible 
into, exchangeable for or evidencing the right to purchase any such shares or 
(ii) amend, alter or repeal the provisions of the Restated Certificate of 
Incorporation, including the Certificate of Designation relating to such 
series of Preferred Stock, whether by merger, consolidation, 

                               18           
<PAGE>
or otherwise, so as to materially and adversely affect any right, preference, 
privilege or voting power of such series of Preferred Stock or the holders 
thereof; provided, however, that any increase in the amount of the authorized 
Preferred Stock or any outstanding series of Preferred Stock or any other 
capital stock of the Company, or the creation and issuance of any other 
series of Preferred Stock or of any other capital stock of the Company, in 
each case ranking on a parity with or junior to the Preferred Stock of such 
series with respect to the payment of dividends or the distribution of assets 
upon liquidation, dissolution or winding up, shall not be deemed to 
materially and adversely affect such rights, preferences, privileges or 
voting powers. 

   The foregoing voting provisions will not apply if, at or prior to the time 
when the act with respect to which such vote would otherwise be required 
shall be effected, all outstanding shares of such series of Preferred Stock 
shall have been redeemed or called for redemption upon proper notice and 
sufficient funds shall have been deposited in trust to effect such 
redemption.

                        DESCRIPTION OF DEBT SECURITIES 

   The Debt Securities may consist of Senior Debt Securities or Subordinated 
Debt Securities. The Senior Debt Securities will be issued under an indenture 
(the "Senior Debt Indenture") between the Company, as issuer, and one or more 
trustees (each a "Trustee") meeting the requirements of a trustee under the 
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The 
Subordinated Debt Securities will be issued under an indenture (the 
"Subordinated Debt Indenture") between the Company, as issuer, and a Trustee. 

   Forms of the Indentures have been filed as exhibits to the Registration 
Statement of which this Prospectus is a part. The Indentures are subject to 
and governed by the Trust Indenture Act. The following summaries of certain 
provisions of the Indentures do not purport to be complete, and where 
reference is made to particular provisions of the Indentures, such 
provisions, including definitions of certain terms, are incorporated by 
reference as a part of such summaries or terms, which are qualified in their 
entirety by such reference. The Indentures are substantially identical except 
for provisions relating to subordination. 

   The Debt Securities may be issued in one or more series. The particular 
terms of each series of Debt Securities, as well as any modifications of or 
additions to the general terms of the Debt Securities as described herein 
that may be applicable in the case of a particular series of Debt Securities, 
will be described in the Prospectus Supplement relating to such series of 
Debt Securities. Accordingly, for a description of the terms of a particular 
series of Debt Securities, reference must be made to both the Prospectus 
Supplement relating thereto and the description of Debt Securities set forth 
in this Prospectus. 

GENERAL 

   Neither of the Indentures limits the amount of Debt Securities that may be 
issued thereunder. Each Indenture provides that Debt Securities issuable 
thereunder may be issued up to the aggregate principal amount which may be 
authorized from time to time by the Company. Reference is made to the 
Prospectus Supplement for the following terms of the Debt Securities (to the 
extent such terms are applicable to such Debt Securities) in respect of which

    method may, but need not be, based on one or more currencies, currency 
    units, composite currencies, commodities, equity indicies or other 
    indicies) and the manner in which such amounts shall be determined;

    be payable, if other than the Person in whose name that Offered Debt 
    Security is registered, and the extent to which, or the manner in which, 
    any interest payable on a temporary global Security on an Interest Payment 
    Date will be paid if other than in the manner provided in the applicable 
    Prospectus Supplement; 

     (xvi) the applicability, if any, of defeasance and covenant defeasance 
    provisions of the applicable Indenture and any provisions in modification 
    of, in addition to or in lieu of any such defeasance or covenant 
    defeasance provisions; 

     (xvii) if the Offered Debt Securities are to be issuable in definitive 
    form (whether upon original issue or upon exchange of a temporary Offered 
    Debt Security) only upon receipt of certain certificates or other

    the conversion period as well as any applicable limitations on the 
    ownership or transferability of the Common Stock or Preferred Stock into 
    which the Offered Debt Securities are convertible; and 

     (xx) any other terms of the Offered Debt Securities not inconsistent with 
    the provisions of the applicable Indenture. 

   As described in each Prospectus Supplement relating to any particular 
series of Debt Securities offered thereby, the Indenture under which such 
Debt Securities are issued may contain covenants 

                               21           
<PAGE>
limiting: (i) the incurrence of debt by the Company; (ii) the incurrence of 
debt by subsidiaries of the Company; (iii) the making of certain payments by 
the Company and its subsidiaries; (iv) business activities of the Company and 
its subsidiaries; (v) the issuance of preferred stock of subsidiaries; (vi) 
asset dispositions; (vii) transactions with affiliates; (viii) liens; and

SENIOR DEBT SECURITIES 

   The payment of principal of, premium, if any, and interest on the Senior 
Debt Securities will, to the extent and in the manner set forth in the Senior 
Debt Indenture, rank pari passu in right of payment with all other existing 
and future unsecured and unsubordinated obligations of the Company. 

SUBORDINATION OF SUBORDINATED DEBT SECURITIES 

   The Subordinated Debt Indenture provides that the Subordinated Debt 
Securities are subordinate and junior in right of payment to all Senior 
Indebtedness of the Company as provided in the Subordinated Debt Indenture. 
No payment of principal of (including redemption payments), or interest on, 
the Subordinated Debt Securities may be made (i) if any Senior Indebtedness 
is not paid when due, any applicable grace period with respect to a default 
thereunder has ended and such default has not been cured or waived, or (ii) 
if the maturity of any Senior Indebtedness has been accelerated because of a 
default. Upon any distribution of assets of the Company to creditors upon any 
dissolution, winding up, liquidation or reorganization, whether voluntary or 
involuntary or in bankruptcy, insolvency, receivership or other proceedings, 
all principal of, and premium, if any, and interest due or to become due on, 
all Senior Indebtedness must be paid in full before the holders of the 
Subordinated Debt Securities are entitled to receive or retain any payment. 
In the event that, notwithstanding the foregoing, any payment or distribution 
of cash, property or securities shall be received or collected by a holder of 
the Subordinated Debt Securities in contravention of the foregoing 
provisions, such payment or distribution shall be held for the benefit of and 
shall be paid over to the holders of Senior Indebtedness or their 
representative or representatives or to the trustee or trustees under any 
indenture under which any instrument evidencing Senior Indebtedness may have 
been issued, as their respective interests may appear, to the extent 
necessary to pay in full all Senior Indebtedness then due, after giving 
effect to any concurrent payment to the holders of Senior Indebtedness. 
Subject to the payment in full of all Senior Indebtedness, the rights of the 
holders of the Subordinated Debt Securities will be subrogated to the rights 
of the holders of Senior Indebtedness to receive payments or distributions 
applicable to Senior Indebtedness until all amounts owing on the Subordinated 
Debt Securities are paid in full. 

   The term "Senior Indebtedness" shall mean in respect of the Company (i) 
the principal, premium, if any, and interest in respect of (A) indebtedness 
of such obligor for money borrowed and (B) indebtedness evidenced by 
securities, bonds or other similar instruments issued by such obligor, (ii) 
all capital lease obligations of such obligor, (iii) all obligations of such 
obligor issued or assumed as the deferred purchase price of property, all 
conditional sale obligations of such obligor and all obligations of such 
obligor under any title retention agreement (but excluding trade accounts 
payable and other similar obligations arising in the ordinary course of 
business), (iv) all obligations of such obligor for the reimbursement of any 
letter of credit, banker's acceptance, security purchase facility or similar 
credit transaction, (v) all obligations of the type referred to in clauses 
(i) through (iv) above of other persons for the payment of which such obligor 
is responsible or liable as obligor, guarantor or otherwise, and (vi) all 
obligations of the type referred to in clauses (i) through (v) above of other 
persons secured by any lien on any property or asset of such obligor (whether 
or not such obligation is assumed by such obligor), except for (1) any such 
indebtedness issued after the date of original issuance of the Subordinated 
Debt Securities that is by its terms subordinated to or pari passu with the 
Subordinated Debt Securities and (2) any indebtedness (including all other 
debt securities and guarantees in respect of those debt securities) initially 
issued to any other trust, or a trustee of such trust, partnership or other 
entity affiliated with the Company that is, directly or indirectly, a 
financing vehicle of the Company (a "Financing Entity") in 

                               22           
<PAGE>
connection with the issuance by such Financing Entity of Convertible 
Preferred Securities or other similar securities. Such Senior Indebtedness 
shall continue to be Senior Indebtedness and entitled to the benefits of the 
subordination provisions irrespective of any amendment, modification or 
waiver of any term of such Senior Indebtedness. 

   The Indenture does not limit the aggregate amount of Senior Indebtedness 
the Company may issue. 

CERTAIN COVENANTS 

   Unless otherwise provided in a Prospectus Supplements with respect to a 
particular series of Offered Debt Securities, each of the Indentures will 
contain certain covenants, including the ones summarized below, which 
covenants will be applicable (unless they are waived or amended or unless the 
Debt Securities are defeased, see "Defeasance" below) so long as any of the 
Debt Securities are outstanding. 

 Limitation on Debt 

   The Company will not Incur any Debt, including Acquisition Debt, unless, 
after giving effect to the incurrence of such Debt and the receipt and 
application of the proceeds therefrom, the Fixed Charge Ratio (as defined in 
the Indenture) of the Company would be equal to or greater than 2.0 to 1. 

   Notwithstanding the foregoing, the Company may Incur each and all of the 
following: (i) Company Refinancing Debt, (ii) Debt of the Company to any of 
its Restricted Subsidiaries or any Eligible Joint Venture that is expressly 
subordinated in right of payment to the Senior Debt Securities of all series, 
in the case of the Senior Debt Indenture or the Subordinated Debt Securities 
of all series in the case of the Subordinated Debt Indenture, provided that 
any transfer of such Debt by a Restricted Subsidiary or an Eligible Joint 
Venture (other than to another Restricted Subsidiary or another Eligible 
Joint Venture), or any transfer of the Company's ownership interest, or a 
portion thereof, in such Restricted Subsidiary or such Eligible Joint Venture 
or the interest, or a portion thereof, of Kiewit in a Permitted Joint Venture 
or an Eligible Joint Venture (which transfer has the effect of causing such 
Restricted Subsidiary or such Eligible Joint Venture to cease to be a 
Restricted Subsidiary or an Eligible Joint Venture, as the case may be), will 
be deemed to be an Incurrence of Debt that is subject to the provisions of 
this covenant other than this clause (ii), (iii) Debt in an aggregate 
principal amount not to exceed $100 million outstanding at any one time may 
be issued under or in respect of Permitted Working Capital Facilities, (iv) 
Non-Recourse Debt Incurred in respect of one or more Permitted Facilities in 
which the Company has a direct or indirect interest, (v) Debt in respect of 
Currency Protection Agreements or Interest Rate Protection Agreements, (vi) 
Purchase Money Debt, provided that the amount of such Debt (net of any 
original issue discount) does not exceed 90% of the fair market value of the 
Property acquired, (vii) the Debt Securities and other Debt outstanding as of 
the date of original issuance of any series of the Debt Securities (other 
than Debt to the extent that it is extinguished, retired, defeased or repaid 
in connection with the original issuance of any series of the Debt 
Securities), including Debt that is Incurred in respect of interest or 
discount on such Debt (or Redeemable Stock issued as dividends in respect of 
Redeemable Stock) pursuant to the terms of the agreement or instrument that 
governs such Debt (or such Redeemable Stock) as in effect on the date of 
original issuance of any series of the Debt Securities and (viii) Debt in an 
aggregate principal amount not to exceed $75 million outstanding at any one 
time. 

 Limitation on Subsidiary Debt 

   The Company will not permit any of its Restricted Subsidiaries or any 
Eligible Joint Venture, to Incur any Debt. 

   Notwithstanding the foregoing, each and all of the following Debt may be 
Incurred by a Restricted Subsidiary or an Eligible Joint Venture: (i) Debt 
outstanding as of the date of original issuance of any series of the Debt 
Securities, (ii) Debt owed by a Restricted Subsidiary or an Eligible Joint 
Venture to the Company or another Restricted Subsidiary of the Company or 
another Eligible Joint Venture that either directly or indirectly owns all or 
a portion of the Company's interest in, or directly or indirectly is owned 
by, such Restricted Subsidiary, or such Eligible Joint Venture, as the case 
may be, (iii) Non-Recourse Debt Incurred in respect of one or more Permitted 
Facilities, provided that such Restricted Subsidiary or such Eligible Joint 
Venture has a direct or an indirect interest (which may include Construction 
Financing 

                               23           
<PAGE>
provided by the Company to the extent permitted under the covenant described 
under "Limitation on Restricted Payments" below as a "Permitted Investment") 
in one or more of such Permitted Facilities in respect of which one or more 
Restricted Subsidiaries or Eligible Joint Ventures shall have a direct or 
indirect interest, (iv) Subsidiary Refinancing Debt, (v) Acquired Debt, (vi) 
Debt in respect of Currency Protection Agreements or Interest Rate Protection 
Agreements, (vii) Permitted Funding Company Loans and (viii) Permitted 
Facilities Debt, provided that at the time of Incurrence thereof and after 
giving effect to the application of the proceeds thereof, the aggregate 
principal amount of Permitted Facilities Debt shall not exceed 15% of total 
consolidated Debt of the Company computed in accordance with GAAP. 

 Limitation on Restricted Payments 

   The Company will not, and will not permit any of its Restricted 
Subsidiaries or any Eligible Joint Venture to, directly or indirectly, make 
any Restricted Payment unless at the time of such Restricted Payment and 
after giving effect thereto (a) no Event of Default and no event that, after 
the giving of notice or lapse of time or both, would become an Event of 
Default, has occurred and is continuing, (b) the Company could Incur at least 
$1 of Debt under the provision described in the first paragraph of 
"Limitation on Debt" above and (c) the aggregate amount of all Restricted 
Payments made by the Company, its Restricted Subsidiaries and the Eligible 
Joint Ventures (the amount so made, if other than in cash, to be determined 
in good faith by the Chief Financial Officer, as evidenced by an Officers' 
Certificate, or, if more than $30 million, by the Board of Directors, as 
evidenced by a Board resolution) after March 24, 1994, is less than the sum 
(without duplication) of (i) 50% of the Adjusted Consolidated Net Income of 
the Company for the period (taken as one accounting period) beginning on the 
first day of the first fiscal quarter that begins after March 24, 1994 and 
ending on the last day of the fiscal quarter immediately prior to the date of 
such calculation, provided that if throughout any fiscal quarter within such 
period the Ratings Categories applicable to the Debt Securities are rated 
Investment Grade by Standard & Poor's Corporation and Moody's Investors 
Service, Inc. (or if both do not make a rating of the Debt Securities 
publicly available, an equivalent Rating Category is made publicly available 
by another Rating Agency), then 100% (instead of 50%) of the Adjusted 
Consolidated Net Income (if more than zero) with respect to such fiscal 
quarter will be included pursuant to this clause (i), and provided further 
that if Adjusted Consolidated Net Income for such period is less than zero, 
then minus 100% of the amount of such net loss, plus (ii) 100% of the 
aggregate net cash proceeds received by the Company from and after [March 24, 
1994] from (A) the issuance and sale (other than to a Restricted Subsidiary 
or an Eligible Joint Venture) of its Capital Stock (excluding Redeemable 
Stock, but including Capital Stock other than Redeemable Stock issued upon 
conversion of, or in exchange for Redeemable Stock or securities other than 
its Capital Stock), (B) the issuance and sale or the exercise of warrants, 
options and rights to purchase its Capital Stock (other than Redeemable 
Stock) and (C) the issuance and sale of convertible Debt upon the conversion 
of such convertible Debt into Capital Stock (other than Redeemable Stock), 
but excluding the net proceeds from the issuance, sale, exchange, conversion 
or other disposition of its Capital Stock (I) that is convertible (whether at 
the option of the Company or the holder thereof or upon the happening of any 
event) into (x) any security other than its Capital Stock or (y) its 
Redeemable Stock or (II) that is Capital Stock referred to in clauses (ii) 
and (iii) of the definition of "Permitted Payment", plus (iii) the net 
reduction in Investments of the types specified in clauses (iv) and (v) of 
the definition of "Restricted Payment" that result from payments of interest 
on Debt, dividends, or repayment of loans or advances, the proceeds of the 
sale or disposition of the Investment or other return of the amount of the 
original Investment to the Company, the Restricted Subsidiary or the Eligible 
Joint Venture that made the original Investment from the Person in which such 
Investment was made, provided that (x) the aggregate amount of such payments 
will not exceed the amount of the original Investment by the Company or such 
Restricted Subsidiary that reduced the amount available pursuant to this 
clause (c) for making Restricted Payments and (y) such payments may be added 
pursuant to this clause (iii) only to the extent such payments are not 
included in the calculation of Adjusted Consolidated Net Income, provided 
further that if Investments of the types specified in clauses (iv) and (v) of 
the Definition of "Restricted Payment" have been made in any Person and such 
Person thereafter becomes a Restricted Subsidiary or an Eligible Joint 
Venture, then the aggregate amount of such Investment (to the extent that it 
has reduced the amount available pursuant to this clause (c) for making 
Restricted Payments), net of the amounts previously added pursuant to this 
clause (iii), may be added to the amount available for 

                               24           
<PAGE>
making Restricted Payments, plus (iv) an amount equal to the principal amount 
of Debt of the Company extinguished in connection with the conversion into 
Common Stock of the Company of the Company's 5% Convertible Subordinated 
Debentures due 2000 and its 9.5% Convertible Subordinated Debenture due 2003. 
The foregoing clause (c) will not prevent the payment of any dividend within 
60 days after the date of its declaration if such dividend could have been 
made on the date of its declaration without violation of the provisions of 
this covenant. 

   None of the Company, any of its Restricted Subsidiaries or any Eligible 
Joint Venture will be deemed to have made an Investment at the time that a 
Person that is a Restricted Subsidiary of the Company or an Eligible Joint 
Venture ceases to be a Restricted Subsidiary or an Eligible Joint Venture 
(other than as a result of being designated as an Unrestricted Subsidiary), 
although any subsequent Investment made by the Company, its Restricted 
Subsidiaries and Eligible Joint Ventures in such Person will be Investments 
that will be subject to the foregoing paragraph unless and until such time as 
such Person becomes a Restricted Subsidiary or an Eligible Joint Venture. 
Notwithstanding the foregoing, (i) the designation of a Restricted Subsidiary 
as an Unrestricted Subsidiary, in the manner provided in the definition of 
"Unrestricted Subsidiary," will be an Investment that will be subject to the 
foregoing paragraph and (ii) the transfer of the Company's interest (or any 
portion thereof) in an entity that has been deemed to be an Eligible Joint 
Venture, directly or indirectly, to an Unrestricted Subsidiary will be an 
Investment (to the extent of the interest transferred) that will be subject 
to the foregoing paragraph. 

   Restricted Payments are defined in the Indentures to exclude Permitted 
Payments, which include Permitted Investments. See "Certain Definitions" 
below. 

 Limitation on Dividends and Other Payment Restrictions Affecting 
Subsidiaries 

   The Company will not, and will not permit any of its Restricted 
Subsidiaries or any Eligible Joint Venture to, create or cause to become, or 
as a result of the acquisition of any Person or Property, or upon any Person 
becoming a Restricted Subsidiary or an Eligible Joint Venture, remain subject 
to, any consensual encumbrance or consensual restriction of any kind on the 
ability of any Restricted Subsidiary or any Eligible Joint Venture to (a) pay 
dividends or make any other distributions permitted by applicable law on any 
Capital Stock of such Restricted Subsidiary or such Eligible Joint Venture 
owned by the Company, any other Restricted Subsidiary or any other Eligible 
Joint Venture, (b) make payments in respect of any Debt owed to the Company, 
any other Restricted Subsidiary of the Company or any Eligible Joint Venture, 
(c) make loans or advances to the Company or to any other Restricted 
Subsidiary of the Company or any other Eligible Joint Venture that is 
directly or indirectly owned by such Restricted Subsidiary or such Eligible 
Joint Venture or (d) transfer any of its Property to the Company or to any 
other Restricted Subsidiary or any other Eligible Joint Venture that directly 
or indirectly owns or is owned by such Restricted Subsidiary or such Eligible 
Joint Venture, other than those encumbrances and restrictions created or 
existing (i) on the date of the original issuance of any series of Debt 
Securities, (ii) pursuant to the Indenture, (iii) in connection with the 
Incurrence of any Debt permitted under the provisions described in clause 
(iii) of the second paragraph of "Limitation on Subsidiary Debt" above, 
provided that, in the case of Debt owed to Persons other than the Company, 
its Restricted Subsidiaries and any Eligible Joint Venture, the Chief 
Executive Officer or the Chief Financial Officer of the Company determines in 
good faith, as evidenced by an Officers' Certificate, that such encumbrances 
or restrictions are required to effect such financing and are not materially 
more restrictive, taken as a whole, on the ability of the applicable 
Restricted Subsidiary or the applicable Eligible Joint Venture to make the 
payments, distributions, loans, advances or transfers referred to in clauses 
(a) through (d) above than encumbrances and restrictions, taken as a whole, 
customarily accepted (or, in the absence of any industry custom, reasonably 
acceptable) in comparable financings or comparable transactions in the 
applicable jurisdiction, (iv) in connection with the execution and delivery 
of an electric power or thermal energy purchase contract, or other contract 
related to the output or product of, or services rendered by one or more 
Permitted Facilities to which such Restricted Subsidiary or such Eligible 
Joint Venture is a supplying party or other contracts with customers, 
suppliers and contractors to which such Restricted Subsidiary or such 
Eligible Joint Venture is a party and where such Restricted Subsidiary or 
such Eligible Joint Venture is engaged, directly or indirectly, in the 
development, design, engineering, procurement, construction, acquisition, 
ownership, management or operation of one or more of such Permitted 
Facilities, provided 

                               25           
<PAGE>
that the Chief Executive Officer or the Chief Financial Officer of the 
Company determines in good faith, as evidenced by an Officers' Certificate, 
that such encumbrances or restrictions are required to effect such contracts 
and are not materially more restrictive, taken as a whole, on the ability of 
the applicable Restricted Subsidiary or the applicable Eligible Joint Venture 
to make the payments, distributions, loans, advances or transfers referred to 
in clauses (a) through (d) above than encumbrances and restrictions, taken as 
a whole, customarily accepted (or, in the absence of any industry custom, 
reasonably acceptable) in comparable financings or comparable transactions in 
the applicable jurisdiction, (v) in connection with any Acquired Debt, 
provided that such encumbrance or restriction was not incurred in 
contemplation of such Person becoming a Restricted Subsidiary or an Eligible 
Joint Venture and provided further that such encumbrance or restriction does 
not extend to any other Property of such Person at the time it became a 
Restricted Subsidiary or an Eligible Joint Venture, (vi) in connection with 
the Incurrence of any Debt permitted under clause (iv) of the provision 
described in the second paragraph of "Limitation on Subsidiary Debt" above, 
provided that, in the case of Debt owed to Persons other than the Company and 
its Restricted Subsidiaries, the Chief Executive Officer or the Chief 
Financial Officer of the Company determines in good faith, as evidenced by an 
Officers' Certificate, that such encumbrances or restrictions taken as a 
whole are not materially more restrictive than the encumbrances and 
restrictions applicable to the Debt and/or equity being exchanged or 
refinanced, (vii) customary non-assignment provisions in leases or other 
contracts entered into in the ordinary course of business of the Company, any 
Restricted Subsidiary or any Eligible Joint Venture, (viii) any restrictions 
imposed pursuant to an agreement entered into for the sale or disposition of 
all or substantially all of the Capital Stock or Property of any Restricted 
Subsidiary or Joint Venture that apply pending the closing of such sale or 
disposition, (ix) in connection with Liens on the Property of such Restricted 
Subsidiary or such Eligible Joint Venture that are permitted by the covenant 
described under "Limitation on Liens" below but only with respect to 
transfers referred to in clause (d) above, (x) in connection with the 
Incurrence of any Debt permitted under clause (ii) of the provisions 
described in the second paragraph of "Limitation on Subsidiary Debt" above or 
(xi) in connection with the Incurrence of any Permitted Facilities Debt 
permitted under clause (viii) of the provisions described in the second 
paragraph of "Limitation on Subsidiary Debt" above, provided that any such 
encumbrance or restriction relates only to those Restricted Subsidiaries or 
Eligible Joint Ventures having a direct or indirect interest in the Permitted 
Facilities in respect of which such Permitted Facilities Debt was Incurred. 

 Limitation on Dispositions 

   Subject to the covenant described under "Mergers, Consolidations and Sales 
of Assets" below, the Company will not make, and will not permit any of its 
Restricted Subsidiaries or any Eligible Joint Venture to make, any Asset 
Disposition unless (i) the Company, the Restricted Subsidiary or the Eligible 
Joint Venture, as the case may be, receives consideration at the time of each 
such Asset Disposition at least equal to the fair market value of the 
Property or securities sold or otherwise disposed of (to be determined in 
good faith by the Chief Financial Officer, as evidenced by an Officers' 
Certificate, or, if more than $30 million, by the Board of Directors, as 
evidenced by a Board resolution), (ii) at least 85% of such consideration is 
received in cash or Cash Equivalents or if less than 85%, the remainder of 
such consideration consists of Property related to the business of the 
Company as described in the first sentence of the covenant described under 
"Limitation on Business" below, and (ii) unless otherwise required under the 
terms of Senior Debt, at the Company's election, the Net Cash Proceeds are 
either (A) invested in the business of the Company, any of its Restricted 
Subsidiaries or any Eligible Joint Venture or (B) applied to the payment of 
any Debt of the Company or any of its Restricted Subsidiaries or any Eligible 
Joint Venture (or as otherwise required under the terms of such Debt), 
provided that, no such payment of Debt (x) under Permitted Working Capital 
Facilities or any other revolving credit agreement will count for this 
purpose unless the related loan commitment, standby facility or the like will 
be permanently reduced by an amount equal to the principal amount so repaid 
or (y) owed to the Company, a Restricted Subsidiary thereof or an Eligible 
Joint Venture will count for this purpose, provided further that such 
investment or such payment, as the case may be, must be made within 365 days 
from the later of the date of such Asset Disposition or the receipt by the 
Company, such Restricted Subsidiary or such Eligible Joint Venture of the Net 
Cash Proceeds related thereto. Any Net Cash Proceeds from Asset 

                               26           
<PAGE>
Dispositions that are not applied as provided in clause (A) or (B) of the 
preceding sentence will constitute "Excess Proceeds." Excess Proceeds will be 
applied, as described below, to make an offer (an "Offer") to purchase any 
series of Debt Securities at a purchase price equal to 100% of the principal 
thereof, plus accrued interest, if any, to the date of purchase. 

   Notwithstanding anything in the foregoing to the contrary, the Company, 
its Restricted Subsidiaries and the Eligible Joint Ventures may exchange with 
other Persons (i) Property that constitutes a Restricted Subsidiary or an 
Eligible Joint Venture for Property that constitutes a Restricted Subsidiary 
or an Eligible Joint Venture, (ii) Property that constitutes a Restricted 
Subsidiary or an Eligible Joint Venture for Property that does not constitute 
a Restricted Subsidiary or an Eligible Joint Venture, (iii) Property that 
does not constitute a Restricted Subsidiary or an Eligible Joint Venture for 
Property that does not constitute a Restricted Subsidiary or an Eligible 
Joint Venture and (iv) Property that does not constitute a Restricted 
Subsidiary or an Eligible Joint Venture for Property that constitutes a 
Restricted Subsidiary or an Eligible Joint Venture, provided that in each 
case the fair market value of the Property received is at least equal to the 
fair market value of the Property exchanged as determined in good faith by 
the Chief Financial Officer, as evidenced by an Officers' Certificate, or, if 
more than $25 million, by the Board of Directors, as evidenced by a Board 
resolution, provided that the Investment in the Property received in the 
exchanges described in clauses (ii) and (iii) of the prior sentence will be 
subject to the covenant described under "Limitation on Restricted Payments" 
above. Notwithstanding anything in the foregoing to the contrary, the Company 
may not, and will not permit any of its Restricted Subsidiaries or any 
Eligible Joint Venture to, make an Asset Disposition of any of their interest 
in, or Property of, any of the Coso Project other than for consideration 
consisting solely of cash. 

   To the extent that any or all of the Net Cash Proceeds of any Foreign 
Asset Disposition are prohibited from (or delayed in) being repatriated to 
the United States by applicable local law, the portion of such Net Cash 
Proceeds so affected will not be required to be applied at the time provided 
above but may be retained by any Restricted Subsidiary or any Eligible Joint 
Venture so long, but only so long, as the applicable local law does not 
permit (or delays) repatriation to the United States. If such Net Cash 
Proceeds are transferred by the Restricted Subsidiary or Eligible Joint 
Venture that conducted the Foreign Asset Disposition to another Restricted 
Subsidiary or Eligible Joint Venture, the Restricted Subsidiary or Eligible 
Joint Venture receiving such Net Cash Proceeds must not be directly or 
indirectly obligated on any Debt owed to any Person other than the Company. 
The Company will take or cause such Restricted Subsidiary or such Eligible 
Joint Venture to take all actions required by the applicable local law to 
permit such repatriation promptly. Once repatriation of any of such Net Cash 
Proceeds is permitted under the applicable local law, repatriation will be 
effected immediately and the repatriated Net Cash Proceeds will be applied in 
the manner set forth in this covenant as if such Asset Disposition had 
occurred on the date of such repatriation. In addition, if the Chief 
Financial Officer determines, in good faith, as evidenced by an Officers' 
Certificate, that repatriation of any or all of the Net Cash Proceeds of any 
Foreign Asset Disposition would have a material adverse tax consequence to 
the Company, the Net Cash Proceeds so affected may be retained outside of the 
United States by the applicable Restricted Subsidiary or the applicable 
Eligible Joint Venture for so long as such material adverse tax consequence 
would continue. Notwithstanding the foregoing provisions of this paragraph to 
the contrary, if applicable local law prohibits (or delays) the repatriation 
of Net Cash Proceeds of a Foreign Asset Disposition but such local law does 
not prohibit the application of such Net Cash Proceeds pursuant to the first 
sentence of the first paragraph of this covenant, the Company may apply such 
Net Cash Proceeds pursuant to such provision. 

   If the series of Debt Securities tendered pursuant to an Offer have an 
aggregate purchase price that is less than the Excess Proceeds available for 
the purchase of such Debt Securities, the Company may use the remaining 
Excess Proceeds for general corporate purposes without regard to the 
provisions of this covenant. The Company will not be required to make an 
Offer pursuant to this covenant if the Excess Proceeds available therefor are 
less than $10 million, provided that the lesser amounts of such Excess 
Proceeds will be carried forward and cumulated for each 36 consecutive month 
period for purposes of determining whether an Offer is required with respect 
to any Excess Proceeds of any subsequent Asset 

                               27           
<PAGE>
Dispositions. Any such lesser amounts so carried forward and cumulated need 
not be segregated or reserved and may be used for general corporate purposes, 
provided that such use will not reduce the amount of cumulated Excess 
Proceeds or relieve the Company of its obligation hereunder to make an Offer 
with respect thereto. 

   The Company will make an Offer by mailing to each Holder, with a copy to 
the Trustee, within 30 days after the receipt of Excess Proceeds that cause 
the cumulated Excess Proceeds to exceed $10 million, a written notice that 
will specify the purchase date, which will not be less than 30 days nor more 
than 60 days after the date of such notice (the "Purchase Date"), that will 
contain certain information concerning the business of the Company that the 
Company believes in good faith will enable the Holders to make an informed 
decision and that will contain information concerning the procedures 
applicable to the Offer (including, without limitation, the right of 
withdrawal) and the effect of such Offer on the Debt Securities tendered. 
Holders that elect to have their Debt Securities purchased will be required 
to surrender such Debt Securities at least one Business Day prior to the 
Purchase Date. If at the expiration of the Offer period the aggregate 
purchase price of the series of Debt Securities properly tendered by Holders 
pursuant to the Offer exceeds the amount of such Excess Proceeds, such series 
of Debt Securities or portions of Debt Securities to be accepted for purchase 
will be selected by the Trustee in such manner as the Trustee deems to be 
fair and appropriate in the circumstances. 

   If the Company is prohibited by applicable law from making the Offer or 
purchasing Debt Securities of any series thereunder, the Company need not 
make an Offer pursuant to this covenant for so long as such prohibition is in 
effect. 

   The Company will comply with all applicable tender offer rules, including, 
without limitation, Rule 14e-1 under the Exchange Act, in connection with an 
Offer. 

 Limitation on Transactions with Affiliates 

   The Company will not, and will not permit any of its Restricted 
Subsidiaries or any Eligible Joint Venture to, directly or indirectly, 
conduct any business or enter into or permit to exist any transaction or 
series of related transactions (including, but not limited to, the purchase, 
sale or exchange of Property, the making of any Investment, the giving of any 
Guarantee or the rendering of any service) with any Affiliate of the Company, 
such Restricted Subsidiary or such Eligible Joint Venture, as the case may 
be, unless (i) such business, transaction or series of related transactions 
is in the best interest of the Company, such Restricted Subsidiary or such 
Eligible Joint Venture, (ii) such business, transaction or series of related 
transactions is on terms no less favorable to the Company, such Restricted 
Subsidiary or such Eligible Joint Venture than those that could be obtained 
in a comparable arm's length transaction with a Person that is not such an 
Affiliate and (iii) with respect to such business, transaction or series of 
related transactions that has a fair market value or involves aggregate 
payments equal to, or in excess of, $10 million, such business, transaction 
or series of transactions is approved by a majority of the Board of Directors 
(including a majority of the disinterested directors), which approval is set 
forth in a Board resolution delivered to the Trustee certifying that, in good 
faith, the Board of Directors believes that such business, transaction or 
series of transactions complies with clauses (i) and (ii) above. 

 Limitation on Liens 

   The Company may not Incur any Debt that is secured, directly or 
indirectly, with, and the Company will not, and will not permit any of its 
Restricted Subsidiaries or an Eligible Joint Venture to, grant a Lien on the 
Property of the Company, its Restricted Subsidiaries or any Eligible Joint 
Venture now owned or hereafter acquired unless contemporaneous therewith or 
prior thereto the Debt Securities are equally and ratably secured except for 
(i) any such Debt secured by Liens existing on the Property of any entity at 
the time such Property is acquired by the Company, any of its Restricted 
Subsidiaries or any Eligible Joint Venture, whether by merger, consolidation, 
purchase of such Property or otherwise, provided that such Liens (x) are not 
created, incurred or assumed in contemplation of such Property being acquired 
by the Company, any of its Restricted Subsidiaries or any Eligible Joint 
Venture and (y) do not extend to any other Property of the Company, any of 
its Restricted Subsidiaries or any Eligible Joint Venture, (ii) any other 
Debt that is required by the terms thereof to be equally and ratably secured 
as a result of the 

                               28           
<PAGE>
Incurrence of Debt that is permitted to be secured pursuant to another clause 
of this covenant, (iii) Liens that are granted in good faith to secure Debt 
(A) contemplated by clause (iv) of the covenant described under "Limitation 
on Debt" above or (B) contemplated by clauses (ii), (iii), (vi) and (viii) of 
the covenant described under "Limitation on Subsidiary Debt" above, provided 
that, in the case of Debt owed to a Person other than the Company or a 
Restricted Subsidiary, the Chief Executive Officer or Chief Financial Officer 
of the Company determines in good faith, as evidenced by an Officers' 
Certificate, that such Liens are required in order to effect such financing 
and are not materially more restrictive, taken as a whole, than Liens, taken 
as a whole, customarily accepted (or in the absence of industry custom, 
reasonably acceptable) in comparable financings or comparable transactions in 
the applicable jurisdiction, (iv) Liens existing on the date of the original 
issuance of any series of the Debt Securities, (v) Liens incurred to secure 
Debt incurred by the Company as permitted by clause (vi) of the covenant 
described under "Limitation on Debt" above, provided that such Liens may not 
cover any Property other than that being purchased and improvements and 
additions thereto, (vi) Liens on any Property of the Company securing 
Permitted Working Capital Facilities, Guarantees thereof and any Interest 
Rate Protection Agreements or Currency Protection Agreements, provided that 
such Liens may not extend to the Capital Stock owned by the Company in any 
Restricted Subsidiary of the Company or any Eligible Joint Venture, (vii) 
Liens in respect of extensions, renewals, refundings or refinancings of any 
Debt secured by the Liens referred to in the foregoing clauses, provided that 
the Liens in connection with such renewal, extension, refunding or 
refinancing will be limited to all or part of the specific property that was 
subject to the original Lien, (viii) Liens incurred to secure obligations in 
respect of letters of credit, bankers' acceptances, surety, bid, operating 
and performance bonds, performance guarantees or other similar instruments or 
obligations (or reimbursement obligations with respect thereto) (in each 
case, to the extent incurred in the ordinary course of business), (ix) any 
Lien arising by reason of (A) any judgment, decree or order of any court, so 
long as such Lien is being contested in good faith and is appropriately 
bonded, and any appropriate legal proceedings that may have been duly 
initiated for the review of such judgment, decree or order have not been 
finally terminated or the period within which such proceedings may be 
initiated has not expired, (B) taxes, duties, assessments, imposts or other 
governmental charges that are not yet delinquent or are being contested in 
good faith, (C) security for payment of worker's compensation or other 
insurance, (D) security for the performance of tenders, contracts (other than 
contracts for the payment of money) or leases, (E) deposits to secure public 
or statutory obligations, or to secure permitted contracts for the purchase 
or sale of any currency entered into in the ordinary course of business, (F) 
the operation of law in favor of carriers, warehousemen, landlords, 
mechanics, materialmen, laborers, employees or suppliers, incurred in the 
ordinary course of business for sums that are not yet delinquent or are being 
contested in good faith by negotiations or by appropriate proceedings that 
suspend the collection thereof, (G) easements, rights-of-way, zoning and 
similar covenants and restrictions and other similar encumbrances or title 
defects that do not in the aggregate materially interfere with the ordinary 
conduct of the business of the Company, any of its Restricted Subsidiaries or 
any Eligible Joint Venture or (H) leases and subleases of real property that 
do not interfere with the ordinary conduct of the business of the Company, 
any of its Restricted Subsidiaries or any Eligible Joint Venture and that are 
made on customary and usual terms applicable to similar properties, or (x) 
Liens, in addition to the foregoing, that secure obligations not in excess of 
$5 million in the aggregate. 

 Purchase of Debt Securities Upon a Change of Control 

   Upon the occurrence of a Change of Control, each Holder of the Debt 
Securities of each series will have the right to require that the Company 
repurchase such Holder's Debt Securities of such series at a purchase price 
in cash equal to 101% of the principal thereof on the date of purchase plus 
accrued interest, if any, to the date of purchase. 

   The Change of Control provisions may not be waived by the Trustee or by 
the Board of Directors, and any modification thereof must be approved by each 
Holder. Nevertheless, the Change of Control provisions will not necessarily 
afford protection to Holders, including protection against an adverse effect 
on the value of the Debt Securities of any series, in the event that the 
Company or its Subsidiaries Incur additional Debt, whether through 
recapitalizations or otherwise. 

                               29           
<PAGE>
   Within 30 days following a Change of Control, the Company will mail a 
notice to each Holder of the Debt Securities of each series, with a copy to 
the Trustee, stating (1) that a Change of Control has occurred and that such 
Holder has the right to require the Company to purchase such Holder's Debt 
Securities at the purchase price described above (the "Change of Control 
Offer"), (2) the circumstances and relevant facts regarding such Change of 
Control (including information with respect to pro forma historical income, 
cash flow and capitalization after giving effect to such Change of Control), 
(3) the purchase date (which will be not earlier than 30 days nor later than 
60 days from the date such notice is mailed) (the "Purchase Date"), (4) and 
thereafter interest on and such Debt Security will continue to accrue, (5) 
any Debt Security properly tendered pursuant to the Change of Control Offer 
will cease to accrue interest after the Purchase Date (assuming sufficient 
moneys for the purchase thereof are deposited with the Trustee), (6) that 
Holders electing to have a Debt Security of any series purchased pursuant to 
a Change of Control Offer will be required to surrender the Debt Security of 
such series, with the form entitled "Option of Holder To Elect Purchase" on 
the reverse of the Debt Security completed, to the paying agent at the 
address specified in the notice prior to the close of business on the fifth 
Business Day prior to the Purchase Date, (7) that a Holder will be entitled 
to withdraw such Holder's election if the paying agent receives, not later 
than the close of business on the third Business Day (or such shorter periods 
as may be required by applicable law) preceding the Purchase Date, a 
telegram, telex, facsimile transmission or letter setting forth the name of 
the Holder, the principal amount of Debt Securities of such series the Holder 
delivered for purchase, and a statement that such Holder is withdrawing his 
election to have such Debt Securities of such series purchased and (8) that 
Holders that elect to have their Debt Securities of any series purchased only 
in part will be issued new Debt Securities having a principal amount equal to 
the portion of the Debt Securities of the series that were surrendered but 
not tendered and purchased. 

   On the Purchase Date, the Company will (i) accept for payment all Debt 
Securities of any series or portions thereof tendered pursuant to the Change 
of Control Offer, (ii) deposit with the Trustee money sufficient to pay the 
purchase price of all Debt Securities of such series or portions thereof so 
tendered for purchase and (iii) deliver or cause to be delivered to the 
Trustee the Debt Securities of such series properly tendered together with an 
Officers' Certificate identifying the Debt Securities of such series or 
portions thereof tendered to the Company for purchase. The Trustee will 
promptly mail, to the Holders of the Debt Securities of such series properly 
tendered and purchased, payment in an amount equal to the purchase price, and 
promptly authenticate and mail to each Holder a new Debt Security of the same 
series having a principal amount equal to any portion of such Holder's Debt 
Securities of such series that were surrendered but not tendered and 
purchased, the Company will publicly announce the results of the Change of 
Control Offer on or as soon as practicable after the Purchase Date. 

   If the Company is prohibited by applicable law from making the Change of 
Control Offer or purchasing Debt Securities of any series thereunder, the 
Company need not make a Change of Control Offer pursuant to this covenant for 
so long as such prohibition is in effect. 

   The Company will comply with all applicable tender offer rules, including, 
without limitation, Rule 14e-1 under the Exchange Act, in connection with a 
Change of Control Offer. 

 Limitation on Business 

   The Company will, and will cause its Restricted Subsidiaries and the 
Eligible Joint Ventures to, engage only in (i) the ownership, design, 
engineering, procurement, construction, development, acquisition, operation, 
servicing, management or disposition of Permitted Facilities, (ii) the 
ownership, creation, development, acquisition, servicing, management or 
disposition of Restricted Subsidiaries and Joint Ventures that own, 
construct, develop, design, engineer, procure, acquire, operate, service, 
manage or dispose of Permitted Facilities, (iii) obtaining, arranging or 
providing financing incident to any of the foregoing and (iv) other related 
activities incident to any of the foregoing. The Company will not, and will 
not permit any of its Restricted Subsidiaries or any Eligible Joint Venture 
to, make any Investment or otherwise acquire any Property that is not 
directly related to the business of the Company as described in the preceding 
sentence (collectively, the "Ineligible Investments") other than as a part of 
an Investment or an acquisition of Property that is predominantly and 
directly related to the business of the Company 

                               30           
<PAGE>
as described above, and if the aggregate fair market value of such Ineligible 
Investments in the aggregate exceeds 20% (the "Percentage Limit") of the 
total assets of the Company and its consolidated Restricted Subsidiaries (as 
determined in accordance with GAAP) as determined in good faith by the Chief 
Financial Officer, as evidenced by an Officers' Certificate, the Company, its 
Restricted Subsidiaries and the Eligible Joint Ventures must cease acquiring 
any additional Ineligible Investments and, within 18 months of the 
acquisition that caused the Ineligible Assets to exceed the Percentage Limit, 
must return to compliance with the Percentage Limit by disposing of 
Ineligible Assets or otherwise, provided that such 18-month period may be 
extended up to an additional six months if, despite the Company's active 
efforts during such 18-month period to dispose of such Ineligible Investments 
or to otherwise come into compliance with such Percentage Limit, the Company 
is unable to do so because of regulatory restrictions or delays or adverse 
market conditions. 

 Limitation on Certain Sale-Leasebacks 

   The Company will not, and will not permit any of its Restricted 
Subsidiaries or any Eligible Joint Venture to, Incur or otherwise become 
obligated with respect to any sale-leaseback (other than a sale-leaseback 
with respect to a Permitted Facility that is Non-Recourse) unless, (i) (a) if 
effected by the Company, the Company would be permitted to Incur such 
obligation under the covenant described under "Limitation on Debt" above or, 
(b) if effected by a Restricted Subsidiary or an Eligible Joint Venture, such 
Restricted Subsidiary or such Eligible Joint Venture would be permitted to 
Incur such obligation under the covenant described under "Limitation on 
Subsidiary Debt" above, assuming for the purpose of this covenant and the 
covenants described under "Limitation on Debt" and "Limitation on Subsidiary 
Debt" that (x) the obligation created by such sale-leaseback is a Capitalized 
Lease and (y) the Capitalized Lease Obligation with respect thereto is the 
Attributable Value thereof, (ii) the Company, such Restricted Subsidiary or 
such Eligible Joint Venture is permitted to grant a Lien with respect to the 
property that is the subject of such sale-leaseback under the covenant 
described under "Limitation on Liens" above, (iii) the proceeds of such 
sale-leaseback are at least equal to the fair market value of the property 
sold (determined in good faith as evidenced by an Officers' Certificate 
delivered to the Trustee in respect of a transaction involving less than $25 
million, or, if equal to or in excess of $25 million, by the Board of 
Directors, as evidenced by a Board resolution) and (iv) the Net Cash Proceeds 
of the sale-leaseback are applied pursuant to the covenants described under 
"Limitation on Dispositions" above. 

 Limitation on Sale of Subsidiary Preferred Stock 

   The Company will not permit any of its Restricted Subsidiaries or any 
Eligible Joint Venture to create, assume or otherwise cause or suffer to 
exist any Preferred Stock except: (i) Preferred Stock outstanding on the date 
of the Indentures, including Preferred Stock issued as dividends in respect 
of such Preferred Stock pursuant to the terms of the agreement or instrument 
that governs such Preferred Stock as in effect on the date of original 
issuance of the Debt Securities, (ii) Preferred Stock held by the Company, a 
Restricted Subsidiary of the Company or an Eligible Joint Venture, (iii)

with or into another Restricted Subsidiary or another Eligible Joint Venture 
or (c) a Restricted Subsidiary, or an Eligible Joint Venture merges with or

Subsidiary or an Eligible Joint Venture), provided that such Preferred Stock 
was not issued in anticipation of such Person becoming a Restricted 
Subsidiary or an Eligible Joint Venture or of such merger, (iv) Preferred 
Stock issued or agreed to be issued by a Restricted Subsidiary or an Eligible 
Joint Venture in connection with the financing of the construction, design,

which the Company or one or more Restricted Subsidiaries or Eligible Joint 
Ventures has a direct or indirect interest or the retirement of Debt or 
Preferred Stock secured by any such Permitted Facility or in order to enhance 
the repatriation of equity, advances or income or the increase of after-tax 
funds available for distribution to the owners of any such Permitted 
Facility, (v) Preferred Stock issued or agreed to be issued by a Restricted 
Subsidiary or an Eligible Joint Venture in satisfaction of legal requirements 
applicable to a Permitted Facility or to maintain the ordinary course of

which are used to refinance, any Preferred Stock permitted to be outstanding 
pursuant to clauses (i) through (v) hereof (or any extension, renewal or 
refinancing thereof), having a liquidation preference not to exceed the 
liquidation preference of the Preferred Stock so exchanged or refinanced and 
having a redemption period no shorter than the redemption period of the 
Preferred Stock so exchanged or refinanced. 

EVENTS OF DEFAULT 

   An Event of Default, as defined in each of the Indentures and applicable 
to any particular series of Debt Securities issued under such Indenture is 
defined as being: (i) default as to the payment of principal, or premium, if 
any, on any Debt Security of that series or as to any payment required in 
connection with a Change of Control or an Asset Disposition, (ii) default as 
to the payment of interest on any Debt Security of that series for 30 days 
after payment is due, (iii) failure to make an offer required under either of 
the covenants described under "Limitation on Dispositions" or "Purchase of 
Debt Securities Upon a Change of Control" above or a failure to purchase Debt 
Securities of that series tendered in respect of such offer, (iv) default in 
the performance, or breach, of any covenant, agreement or warranty contained 
in the Indentures and the Debt Securities of that series and such failure 
continues for 30 days after written notice is given to the Company by the 
Trustee or the Holders of at least 25% in principal amount outstanding of the 
Debt Securities of that series issued under such Indenture, as provided in 
such Indenture, (v) default on any other Debt of the Company or any 
Significant Subsidiary (other than Non-Recourse Debt of Significant 
Subsidiaries) if either (x) such default results from failure to pay 
principal of such Debt in excess of $25 million when due after any applicable 
grace period or (y) as a result of such default, the maturity of such Debt 
has been accelerated prior to its scheduled maturity and such default has not 
been cured within the applicable grace period, and such acceleration has not 
been rescinded, and the principal amount of such Debt, together with the 
principal amount of any other Debt of the Company and its Significant 
Subsidiaries (not including Non-Recourse Debt of the Significant 
Subsidiaries) that is in default as to principal, or the maturity of which 
has been accelerated, aggregates $25 million or more, (vi) the entry by a 
court of one or more judgments or orders against the Company or any 
Significant Subsidiary for the payment of money that in the aggregate exceeds 
$25 million (excluding the amount thereof covered by insurance or by a bond 
written by a Person other than an Affiliate of the Company), which judgments 
or orders have not been vacated, discharged or satisfied or stayed pending 
appeal within 60 days from the entry thereof, provided that such a judgment 
or order will not be an Event of Default if such judgment or order does not 
require any payment by the Company or any Significant Subsidiary, except to 
the extent that such judgment is only against Property that secures 
Non-Recourse Debt that was permitted under the Indentures, and the Company 
could, at the expiration of the applicable 60 day period, after giving effect 
to such judgment or order and the consequences thereof, Incur at least $1 of 
Debt under the provisions described in the first paragraph of "Limited on 
Debt" above, and (vii) certain events involving bankruptcy, insolvency or 
reorganization of the Company or any of its Significant Subsidiaries. 

   The Indentures provide that the Trustee may withhold notice to the Holders 
of any default (except in payment of principal of, premium, if any, or 
interest on any series of Debt Securities and any payment required in 
connection with a Change of Control or an Asset Disposition) if the Trustee 
considers it in the interest of Holders to do so. 

   The Indentures provide that if an Event of Default with respect to Debt 
Securities of any series at the time outstanding (other than an event of 
bankruptcy, insolvency or reorganization of the Company or a Significant 
Subsidiary) has occurred and is continuing, either the Trustee or the Holders 
of not less than 25% in principal amount of the Debt Securities of that 
series issued under such Indenture then outstanding may declare the Default 
Amount of all Debt Securities of that series to be due and payable 
immediately, but upon certain conditions such declaration may be annulled and 
past defaults (except, unless theretofore cured, a default in payment of 
principal of, premium, if any, or interest on the Debt Securities of that 
series or any payment required in connection with a Change of Control or an 
Asset Disposition, as the case may be) may be waived by the Holders of a 
majority in principal amount of the 

                               32           
<PAGE>
Debt Securities of that series then outstanding. If an Event of Default due 
to the bankruptcy, insolvency or reorganization of the Company or a 
Significant Subsidiary occurs, the Indenture provides that the Default Amount 
of all Debt Securities of that series will become immediately due and 
payable. 

   The Holders of a majority in principal amount of the Debt Securities of 
any series issued under such Indenture then outstanding will have the right 
to direct the time, method and place of conducting any proceeding for any 
remedy available to the Trustee under the Indenture with respect to the Debt 
Securities of such series, subject to certain limitations specified in the 
Indenture, provided that the Holders of Debt Securities of such series must 
have offered to the Trustee reasonable indemnity against expenses and 
liabilities. Each Indenture requires the annual filing by the Company with 
the Trustee of a written statement as to compliance with the principal 
covenants contained in the Indentures. 

MODIFICATION 

   Each of the Indentures contains provisions permitting the Company and the 
Trustee, with the consent of the Holders of not less than a majority in 
principal amount of the Debt Securities at the time outstanding, to modify 
such Indenture or any supplemental indenture or the rights of the Holders of 
the series of Debt Securities issued under such Indenture, except that no 
such modification may (i) extend the final maturity of any of the Debt 
Securities, reduce the principal amount thereof, reduce any amount payable on 
redemption or purchase thereof or impair the right of any Holder to institute 
suit for the payment thereof or make any change in the covenants regarding a 
Change of Control or an Asset Disposition or the related definitions without 
the consent of the Holder of each of the series of Debt Securities so 
affected or (ii) reduce the percentage of any series of Debt Securities, the 
consent of the Holders of which is required for any such modification, 
without the consent of the Holders of all series of Debt Securities issued 
under such Indenture then outstanding. 

MERGERS, CONSOLIDATIONS AND SALES OF ASSETS 

   The Company may not consolidate with, merge with or into, or transfer all 
or substantially all its Property (as an entirety or substantially an 
entirety in one transaction or a series of related transactions), to any 
Person unless: (i) the Company will be the continuing Person, or the Person 
(if other than the Company) formed by such consolidation or into which the 
Company is merged or to which the Property of the Company is transferred will 
be a corporation organized and existing under the laws of the United States 
or any State thereof or the District of Columbia and will expressly assume in 
writing all the obligations of the Company, under the Indenture and the Debt 
Securities, (ii) immediately after giving effect to such transaction, no 
Event of Default and no event or condition that through the giving of notice 
or lapse of time or both would become an Event of Default will have occurred 
and be continuing, (iii) immediately after giving effect to such transaction 
on a pro forma basis, the Company or the surviving entity would be able to 
Incur at least $1 of Debt under the provision described in the first 
paragraph of "Limitation on Debt" above and (iv) the Net Worth of the Company 
or the surviving entity, as the case may be, on a pro forma basis after 
giving effect to such transaction (without giving effect to the fees and 
expenses incurred in respect of such transaction), is not less than the Net 
Worth of the Company immediately prior to such transaction. 

   None of the Company, any of its Restricted Subsidiaries or any Eligible 
Joint Ventures may merge with or into, or be consolidated with, an 
Unrestricted Subsidiary of the Company, except to the extent that such 
Unrestricted Subsidiary has been designated a Restricted Subsidiary as 
provided in the Indenture in advance of or in connection with such merger. 

DEFEASANCE AND DISCHARGE 

 Legal Defeasance 

   Each of the Indentures provides that the Company will be deemed to have 
paid and will be discharged from any and all obligations in respect of the 
Debt Securities of or within any series, on the 123rd day after the deposit 
referred to below has been made (or immediately if an Opinion of Counsel is 
delivered to the effect described in clause (B)(iii)(y) below), and the 
provisions of such Indenture will 

                               33           
<PAGE>
cease to be applicable with respect to such Debt Securities of such series 
(except for, among other matters, certain obligations to register the 
transfer or exchange of such Debt Securities of such series, to replace 
stolen, lost or mutilated Debt Securities of such series, to maintain paying 
agencies and to hold monies for payment in trust) if, among other things, (A) 
the Company has deposited with the Trustee, in trust, money and/or U.S. 
Government Obligations that through the payment of interest and principal in 
respect thereof in accordance with their terms will provide money in an 
amount sufficient to pay the principal of, premium, if any, and accrued 
interest on the applicable Debt Securities, on the respective Stated 
Maturities of the Debt Securities or, if the Company makes arrangements 
satisfactory to the Trustee for the redemption of the Debt Securities prior 
to their Stated Maturity, on any earlier redemption date in accordance with 
the terms of such Indenture and the applicable Debt Securities, (B) the 
Company has delivered to the Trustee (i) either (x) an Opinion of Counsel to 
the effect that Holders will not recognize income, gain or loss for federal 
income tax purposes as a result of such deposit, defeasance and discharge and 
will be subject to federal income tax on the same amount and in the same 
manner and at the same times as would have been the case if such deposit, 
defeasance and discharge had not occurred and the Company had paid or 
redeemed such Debt Securities on the applicable dates, which Opinion of 
Counsel must be based upon a ruling of the Internal Revenue Service to the 
same effect or a change in applicable federal income tax law or related 
Treasury regulations after the date of the Indentures or (y) a ruling 
directed to the Trustee or the Company received from the Internal Revenue 
Service to the same effect as the aforementioned Opinion of Counsel, (ii) an 
Opinion of Counsel to the effect that the creation of the defeasance trust 
does not violate the Investment Company Act of 1940 and (iii) an Opinion of 
Counsel to the effect that either (x) after the passage of 123 days following 
the deposit, the trust fund will not be subject to the effect of Section 547 
or 548 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and 
Creditor Law or (y) based upon existing precedents, if the matter were 
properly briefed, a court should hold that the deposit of moneys and/or U.S. 
Government Obligations as provided in clause (A) would not constitute a 
preference voidable under Section 547 or 548 of the U.S. Bankruptcy Code or 
Section 15 of the New York Debtor and Creditor Law, (C) immediately after 
giving effect to such deposit on a pro forma basis, no Event of Default, or 
event that after the giving of notice or lapse of time or both would become 
an Event of Default, will have occurred and be continuing on the date of such 
deposit or (unless an Opinion of Counsel is delivered to the effect described 
in clause (B)(iii)(y) above) during the period ending on the 123rd day after 
the date of such deposit and the deposit will not result in a breach or 
violation of, or constitute a default under, any other agreement or 
instrument to which the Company is a party or by which the Company is bound 
and (D) if at such time the Debt Securities are listed on a national 
securities exchange, the Company has delivered to the Trustee an Opinion of 
Counsel to the effect that the Debt Securities will not be delisted as a 
result of such deposit, defeasance and discharge. 

 Covenant Defeasance 

   The Indentures further provide that the provisions of clause (iii) under 
"Mergers, Consolidations and Sales of Assets" and all the covenants described 
herein under "Certain Covenants," clause (iv) under "Events of Default" with 
respect to such covenants and with respect to clause (iii) under "Mergers, 
Consolidations and Sales of Assets," clauses (i) and (iii) with respect to 
certain offers for any series of Debt Securities required by certain 
covenants and clauses (v) and (vi) under "Events of Default" will cease to be 
applicable to the Company, its Restricted Subsidiaries and its Eligible Joint 
Ventures upon the satisfaction of the provisions described in clauses (A), 
(B)(ii) and (iii), (C) and (D) of the preceding paragraph and the delivery by 
the Company to the Trustee of an Opinion of Counsel to the effect that, among 
other things, the Holders of such Debt Securities will not recognize income, 
gain or loss for federal income tax purposes as a result of such deposit and 
the defeasance of certain covenants and Events of Default and will be subject 
to federal income tax on the same amount and in the same manner and at the 
same times as would have been the case if such deposit and defeasance had not 
occurred and the Company had paid or redeemed such Debt Securities on the 
applicable dates. 

 Defeasance and Certain Other Events of Default 

   If the Company exercises its option to omit compliance with certain 
covenants and provisions of the Indentures with respect to the Debt 
Securities of any series as described in the immediately preceding paragraph 
and any series of Debt Securities are declared due and payable because of the 
occurrence of 

                               34           
<PAGE>
an Event of Default that remains applicable, the amount of money and/or U.S. 
Government Obligations on deposit with the Trustee will be sufficient to pay 
amounts due on such Debt Securities at the time of their Stated Maturity or 
scheduled redemption, but may not be sufficient to pay amounts due on such 
Debt Securities at the time of acceleration resulting from such Event of 
Default. The Company will remain liable for such payments. 

GOVERNING LAW 

   The Indentures and the Debt Securities will be governed by, and construed 
in accordance with, the law of the State of New York, including Section 
5-1401 of the New York General Obligations Law, but otherwise without regard 
to conflict of laws rules.

Person could have been Incurred by the Company at the time of such merger or 
acquisition pursuant to the provision described in the first paragraph of 
"Limitation on Debt" above, and provided further that such Debt was not 
Incurred in connection with, or in contemplation of, such merger or such 
Person becoming a Restricted Subsidiary of the Company or an Eligible Joint 
Venture. 

   "Acquisition Debt" is defined to mean Debt of any Person existing at the 
time such Person is merged into the Company or assumed in connection with the 
acquisition of Property from any such Person (other than Property acquired in 
the ordinary course of business), including Debt Incurred in connection with,

excluding Debt of such Person that is extinguished, retired or repaid in 
connection with such merger or acquisition). 

   "Adjusted Consolidated Net Income" is defined to mean for any period, for 
any Person (the "Referenced Person") the aggregate Net Income (or loss) of 
the Referenced Person and its consolidated Subsidiaries for such period 
determined in conformity with GAAP, provided that the following items will be

(i) the Net Income (or loss) of any other Person (other than a Subsidiary of 
the Referenced Person) in which any third Person has an interest, except to 
the extent of the amount of dividends or other distributions actually paid in 
cash to the Referenced Person during such period, or after such period and on

judgment, decree, order, statute, rule or governmental regulation applicable 
to that Subsidiary, (iv) any gains or losses (on an after-tax basis) 
attributable to Asset Sales (except, solely for the purposes of calculating

Payments" above, any gains or losses of the Company and any of its Restricted 
Subsidiaries from Asset Sales of Capital Stock of Unrestricted Subsidiaries), 
(v) the cumulative effect of a change in accounting principles and (vi) any 
amounts paid or accrued as dividends on Preferred Stock of any Subsidiary of 
the Referenced Person that is not held by the Referenced Person or another

Subsidiaries." 

   "Affiliate" of any Person is defined to mean any other Person directly or 
indirectly controlling or controlled by or under direct or indirect common 
control with such Person. For the purposes of this definition, "control"

by" and "under common control with") when used with respect to any Person 
means the possession, directly or indirectly, of the power to direct or cause 
the direction of the management and policies of such Person, whether through 
the ownership of voting securities, by contract or otherwise. For the purpose 
of the covenant described under "Limitation on Transactions with Affiliates" 
above, the term "Affiliate" will be deemed to include only Kiewit, any entity 
owning beneficially 10% or more of the Voting Stock of the Company and their 
respective Affiliates other than the Restricted Subsidiaries and the Eligible 
Joint Ventures and the other equity investors in the Restricted Subsidiaries

Eligible Joint Venture to any Person (other than to the Company, a Restricted 
Subsidiary of the Company or an Eligible Joint Venture and other than in the 
ordinary course of business) of any Property of the Company, any of its 
Restricted Subsidiaries or any Eligible Joint Venture other than any shares 
of Capital Stock of the Unrestricted Subsidiaries. Notwithstanding the 
foregoing to the contrary, the term "Asset Disposition" will include the 
sale, transfer, conveyance or other disposition of any shares of Capital 
Stock of any Unrestricted Subsidiary to the extent that the Company or any of 
its Restricted Subsidiaries or Eligible Joint Ventures made an Investment in 
such Unrestricted Subsidiary pursuant to clause (vii) of the definition of 
"Permitted Payment," and the Company will, and will cause each of its 
Restricted Subsidiaries and Eligible Joint Ventures to, apply pursuant to the 
covenant described under "Limitation on Dispositions" that portion of the Net 
Cash Proceeds from the sale, transfer, conveyance or other disposition of 
such Unrestricted Subsidiary that is equal to the portion of the total 
Investment in such Unrestricted Subsidiary that is represented by the 
Investment that was made pursuant to clause (vii) of the definition of 
"Permitted Payment." For purposes of this definition, any disposition in 
connection with directors' qualifying shares or investments by foreign 
nationals mandated by applicable law will not constitute an Asset 
Disposition. In addition, the term "Asset Disposition" will not include (i) 
any sale, transfer, conveyance, lease or other disposition of the Capital 
Stock or Property of Restricted Subsidiaries or Eligible Joint Ventures 
pursuant to the terms of any power sales agreements or steam sales agreements

parties on the date of the original issuance of any series of the Debt 
Securities or pursuant to the terms of any power sales agreements or steam 
sales agreements, or other agreements or contracts that are related to the 
output or product of, or services rendered by, a Permitted Facility as to 
which such Restricted Subsidiary or such Eligible Joint Venture is the 
supplying party, to which such Restricted 

                               36           
<PAGE>
Subsidiaries or such Eligible Joint Ventures become a party after such date 
if the Chief Executive Officer or Chief Financial Officer of the Company 
determines in good faith (evidenced by an Officers' Certificate) that such 
provisions are customary (or, in the absence of any industry custom, 
reasonably necessary) in order to effect such agreements and are reasonable 
in light of comparable transactions in the applicable jurisdiction, (ii) any 
sale, transfer, conveyance, lease or other disposition of Property governed 
by the covenant described under "Mergers, Consolidations and Sales of Assets" 
above, (iii) any sale, transfer, conveyance, lease or other disposition of

include (i) the grant of or realization upon a Lien permitted under the 
covenant described under "Limitation on Liens" above or the exercise of 
remedies thereunder, (ii) a sale-leaseback transaction involving 
substantially all the Property constituting a Permitted Facility pursuant to

Subsidiary or the Eligible Joint Venture leases the Permitted Facility from 
such Person, (iii) dispositions of Capital Stock, contract rights, 
development rights and resource data made in connection with the initial 
development of Permitted Facilities, or the formation or capitalization of

required to commence commercial operation has been funded or (iv) 
transactions determined in good faith by the Chief Financial Officer, as 
evidenced by an Officers' Certificate, made in order to enhance the 
repatriation of Net Cash Proceeds for a Foreign Asset Disposition or in order 
to increase the after-tax proceeds thereof available for immediate 
distribution to the Company. Any Asset Disposition that results from the bona 
fide exercise by any governmental authority of its claimed or actual power of 
eminent domain need not comply with the provisions of clauses (i) and (ii) of 
the covenant described under "Limitation on Dispositions" above. Any Asset 
Disposition that results from a casualty loss need not comply with the 
provisions of clause (i) of the covenant described under "Limitation on 
Dispositions" above.

to close. 

   "Capital Stock" is defined to mean, with respect to any Person, any and

bank deposits or Investments are required to effect such financings and are 
not materially more restrictive, taken as a whole, than comparable

or (x) any Person to the extent made with Capital Stock (other than

   "Permitted Joint Venture" is defined to mean a Joint Venture (i) that is

applicable non-U.S. law restricts the amount of Capital Stock that the 
Company may own, the Company must own at least 70% of the amount of Capital 
Stock that it may own pursuant to such law, which in any event must be not 
less than 35% of the total outstanding Capital Stock therein and (iii) in

veto any material act or decision) in connection with such management or 
operation. Any Joint Venture that is a Permitted Joint Venture pursuant to 
this definition because of the ownership of Capital Stock therein by Kiewit 
will cease to be a Permitted Joint Venture if (x) Kiewit disposes of any 
securities issued by the Company and, as a result of such disposition, Kiewit 
becomes the beneficial owner (as such term is defined under Rule 13d-3 or any 
successor rule or regulation promulgated under the Exchange Act) of less than 
25% of the outstanding shares of Voting Stock of the Company or (y) (I) as a 
result of any action other than a disposition of securities by Kiewit, Kiewit 
becomes the beneficial owner of less than 25% of the outstanding shares of 
Voting Stock of the Company and (II) thereafter Kiewit disposes of any 
securities issued by the Company as a result of which the beneficial 
ownership by Kiewit of the outstanding Voting Stock of the Company is further 
reduced, provided that thereafter such Joint Venture may become a Permitted 
Joint Venture if Kiewit becomes the beneficial owner of at least 25% of the 
outstanding shares of Voting Stock of the Company and the other conditions 
set forth in this definition are fulfilled.

Stock other than Redeemable Stock, (iii) any defeasance, redemption, purchase 
or other acquisition for value of any Debt that by its terms ranks 
subordinate in right of payment to the Debt Securities with the proceeds from 
the issuance of (x) Debt that is subordinate to the Debt Securities at least 
to the extent and in the manner as the Debt to be defeased, redeemed, 
purchased or otherwise acquired is subordinate in right of payment to the 
Debt Securities, provided that such subordinated Debt provides for no 
mandatory payments of principal by way of sinking fund, mandatory redemption 
or otherwise (including defeasance) by the Company (including, without 
limitation at the option of the holder thereof other than an option given to 
a holder pursuant to a "change of control" or an "asset disposition" covenant 
that is no more favorable to the holders of such Debt than comparable 
covenants for the Debt being defeased, redeemed, purchased or acquired or, if 
none, the covenants described under "Limitation on Dispositions" and 
"Purchase of Debt Securities Upon a Change of Control" above and such Debt is 
not in an amount (net of any original issue discount) greater than, any 
Stated Maturity of the Debt being replaced and the proceeds of such 
subordinated Debt are utilized for such purpose within 45 days of issuance or 
(y) Capital Stock (other than Redeemable Stock), (iv) Restricted Payments in 
an amount not to exceed $75 million in the aggregate provided that no payment

Default, has occurred and is continuing, (v) any payment or Investment 
required by applicable law in order to conduct business operations in the 
ordinary course, (vi) a Permitted Investment and (vii) Investments in

million in the aggregate, provided that no payment or Investment may be made 
pursuant to this clause (vii) if an Event of Default, or an event that, after 
giving notice or lapse of time or both, would become an Event of Default, has 
occurred and is continuing. Notwithstanding the foregoing, the amount of 
Investments that may be made pursuant to clauses (iv) or (vii), as the case 
may be, may be increased by the net reduction in Investments of the type made 
previously pursuant to clauses (iv) or (vii), as the case may be, that result 
from payments of interest on Debt, dividends, or repayment of loans or 
advances, the proceeds of the sale or disposition of the Investment or other 
return of the amount of the original Investment to the Company, the 
Restricted Subsidiary or the Eligible Joint Venture that made the original 
Investment from the Person in which such Investment was made or any 
distribution or payment of such Investment to the extent that such 
distribution or payment constituted either a Restricted Payment or a 
Permitted Payment, provided that (x) the aggregate amount of such payments 
will not exceed the amount of the original Investment by the Company, such 
Restricted Subsidiary or Eligible Joint Venture that reduced the amount 
available pursuant to clause (iv) or clause (vii), as the case may be, for 
making Restricted Payments and (y) such payments may be added pursuant to 
this proviso only to the extent such payments are not included in the 
calculation of Adjusted Consolidated Net Income. 

   "Permitted Working Capital Facilities" is defined to mean one or more loan

and -for S&P, 1, 2 and 3 for Moody's or the equivalent gradations for another 
Rating Agency) will be taken into account (e.g., with respect to S&P, a 
decline in a rating from BB+ to BB, as well as from BB-to B+, will constitute 
a decrease of one gradation). 

   "Rating Decline" is defined to mean the occurrence of the following on, or 
within 90 days after, the earlier of (i) the occurrence of a Change of 
Control and (ii) the date of public notice of the occurrence of a Change of

gradations (including gradations within Rating Categories as well as between

prior to the Stated Maturity of any series of Debt Securities, provided that 
any Capital Stock that would not constitute Redeemable Stock but for 
provisions thereof giving holders thereof the right to require the Company to 
purchase or redeem such Capital Stock upon the occurrence of an "asset sale" 
or a "change of control" occurring prior to the Stated Maturity of any series 
of Debt Securities will not constitute Redeemable Stock if the "asset sale" 
or "change of control" provision applicable to such Capital Stock is no more 
favorable to the holders of such Capital Stock than the provisions contained 
in the covenants described under "Limitation on Dispositions" and "Purchase 
of Debt Securities Upon a Change of Control" above and such Capital Stock 
specifically provides that the Company will not purchase or redeem any such 
Capital Stock pursuant to such covenants prior to the Company's purchase of

Upon a Change of Control" above.

Investment that was made pursuant to clause (vii) of the definition of 
"Permitted 

                               48

defeasance, redemption, purchase or other acquisition or retirement for value 
prior to the scheduled maturity of any Debt ranked subordinate in right of 
payment to the Senior Debt Securities in the case of the Senior Debt 
Indenture and the Subordinated Debt Securities other than repayment of Debt 
of the Company to a Restricted Subsidiary or an Eligible Joint Venture, (iv) 
any Investment made in a Person (other than the Company or any Restricted 
Subsidiary or any Eligible Joint Venture) and (v) designating a Restricted 
Subsidiary as an Unrestricted Subsidiary (the Restricted Payment made upon 
such a designation to be determined as the fair market value of the Capital 
Stock of such Restricted Subsidiary owned directly or indirectly by the 
Company at the time of the designation). Notwithstanding the foregoing, 
"Restricted Payment" will not include any Permitted Payment, except that any 
payment made pursuant to clauses (iv) and (v) of the definition of "Permitted 
Payment" will be counted in the calculation set forth in clause (c) of the 
covenant described under "Limitation on Restricted Payments." 

   "Restricted Subsidiary" is defined to mean any Subsidiary of the Company

value) and expenses related to such exchange or refinancing), for which 
purpose the amount so exchanged or refinanced will not exceed, in the case of 
Debt, the lesser of (x) the principal amount of the Debt so exchanged or

   As more fully described in the Prospectus Supplement, each of the 
Indentures also provides for defeasance of certain covenants. 

CERTIFICATED SECURITIES 

   Except as may be set forth in a Prospectus Supplement, Debt Securities 
will not be issued in certificated form. If, however, Debt Securities of any 
series are to be issued in certificated form, no service charge will be made 
for any transfer or exchange of any such Debt Securities, but the Company may 
require payment of a sum sufficient to cover any tax or other governmental 
charge payable in connection therewith. 

BOOK-ENTRY SYSTEM 

   If so specified in any accompanying Prospectus Supplement relating to Debt 
Securities of any series, Debt Securities of or within such series may be 
issued under a book-entry system in the form of one or 

                               50           
<PAGE>
more global securities (each, a "Global Security"). Each Global Security will 
be deposited with, or on behalf of, a depositary, which, unless otherwise 
specified in the accompanying Prospectus Supplement, will be The Depository 
Trust Company, New York, New York (the "Depositary"). The Global Securities 
will be registered in the name of the Depositary or its nominee. 

   The Depositary is a limited-purpose trust company organized under the New 
York Banking Law, a "banking organization" within the meaning of the New York 
Banking Law, a member of the Federal Reserve System, a "clearing corporation" 
within the meaning of the New York Uniform Commercial Code, and a "clearing 
agency" registered pursuant to the provisions of Section 17A of the Exchange 
Act. The Depositary holds securities that its participants ("Participants") 
deposit with the Depositary. The Depositary also facilitates the settlement 
among Participants of securities transactions, such as transfers and pledges, 
in deposited securities through electronic computerized book-entry changes in 
Participants' accounts, thereby eliminating the need for physical movement of 
securities certificates. Direct Participants include securities brokers and 
dealers, banks, trust companies, clearing corporations, and certain other 
organizations. The Depositary is owned by a number of its Direct Participants 
and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc. 
and the National Association of Securities Dealers, Inc. Access to the 
Depositary system is also available to others such as securities brokers and 
dealers, banks, and trust companies that clear through or maintain a 
custodial relationship with a Direct Participant, either directly or 
indirectly ("Indirect Participants"). The rules applicable to the Depositary 
and its Participants are on file with the SEC. 

   Purchases of the Offered Securities under the Depositary system must be 
made by or through Direct Participants, which will receive a credit for the 
Securities on the Depositary's records. The ownership interest of each actual 
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on 
the Direct and Indirect Participants' records. Beneficial Owners will not 
receive written confirmation from the Depositary of their purchase, but 
Beneficial Owners are expected to receive written confirmations providing 
details of the transaction, as well as periodic statements of their holdings, 
from the Direct or Indirect Participant through which the Beneficial Owner 
entered into the transaction. Transfers of ownership interests in the 
Securities are to be accomplished by entries made on the books of 
Participants acting on behalf of Beneficial Owners. Beneficial Owners will 
not receive certificates representing their ownership interests in 
Securities, except in the event that use of the book-entry system for the 
Securities is discontinued. 

   To facilitate subsequent transfers, all Securities deposited by 
Participants with the Depositary are registered in the name of the 
Depositary's partnership nominee, Cede & Co. The deposit of Securities with 
the Depositary and their registration in the name of Cede & Co. effect no 
change in beneficial ownership. The Depositary has no knowledge of the actual 
Beneficial Owners of the Securities; the Depositary's records reflect only 
the identity of the Direct Participants to whose accounts such Securities are 
credited, which may or may not be the Beneficial Owners. The Participants 
will remain responsible for keeping account of their holdings on behalf of 
their customers. 

   Conveyance of notices and other communications by the Depositary to Direct 
Participants, by Direct Participants to Indirect Participants, and by Direct 
Participants and Indirect Participants to Beneficial Owners will be governed 
by arrangements among them, subject to any statutory or regulatory 
requirements as may be in effect from time to time. 

   Neither the Depositary nor Cede & Co. will consent or vote with respect to 
the Securities. Under its usual procedures, the Depositary mails an Omnibus 
Proxy to the Company as soon as possible after the record date. The Omnibus 
Proxy assigns Cede & Co.'s consenting or voting rights to those Direct 
Participants to whose accounts the Securities are credited on the record date 
(identified in a listing attached to the Omnibus Proxy). 

   Principal and interest payments on the Securities will be made to the 
Depositary. The Depositary's practice is to credit Direct Participants' 
accounts on the payable date in accordance with their respective holdings 
shown on the Depositary's records unless the Depositary has reason to believe 
that it will not receive payment on the payable date. Payments by 
Participants to Beneficial Owners will be governed by standing instructions 
and customary practices, as is the case with securities held for the accounts 
of 

                               51           
<PAGE>
customers in bearer form or registered in "street name," and will be the 
responsibility of such Participant and not of the Depositary, agent, or the 
Company, subject to any statutory or regulatory requirements as may be in 
effect from time to time. Payment of principal and interest to the Depositary 
is the responsibility of the Depositary, and disbursement of such payments to 
the Beneficial Owners shall be the responsibility of Direct and Indirect 
Participants. 

   The Depositary may discontinue providing its services as securities 
depository with respect to the Securities at any time by giving reasonable 
notice to the Company. Under such circumstances, in the event that a 
successor securities depository is not obtained, Security certificates are 
required to be printed and delivered. The Company may decide to discontinue 
use of the system of book-entry transfers through the Depositary (or a 
success securities depository). In that event, Security certificates will be 
printed and delivered. 

   The information in this section concerning the Depositary and the 
Depositary's book-entry system has been obtained from sources that the 
Company believes to be reliable, but the Company takes no responsibility for 
the accuracy thereof. 

   A Global Security of any series may not be transferred except as a whole 
by the Depositary to a nominee or successor of the Depositary or by a nominee 
of the Depositary to another nominee of the Depositary. A Global Security 
representing all but not part of an offering of Offered Debt Securities 
hereby is exchangeable for Debt Securities in definitive form of like tenor 
and terms if (i) the Depositary notified the Company that it is unwilling or 
unable to continue as depositary for such Global Security or if at any time 
the Depositary is no longer eligible to be or in good standing as a clearing 
agency registered under the Exchange Act, and in either case, a successor 
depositary is not appointed by the Company within 90 days of receipt by the 
Company of such notice or of the Company becoming aware of such 
ineligibility, or (ii) the Company in its sole discretion at any time 
determines not to have all of the Debt Securities represented in an offering 
of Offered Debt Securities by a Global Security and notifies the Trustee 
thereof. A Global Security exchangeable pursuant to the preceding sentence 
shall be exchangeable for Debt Securities registered in such names and in 
such authorized denominations as the Depositary of such Global Security shall 
direct.

                             PLAN OF DISTRIBUTION 

   The Company may sell the Offered Securities in any of the following ways 
(or in any combination thereof): (i) through underwriters or dealers; (ii) 
directly to a limited number of purchasers or to a single purchaser; or (iii) 
through agents. The Prospectus Supplement with respect to any Offered 
Securities will set forth the terms of the offering of such Offered 
Securities, including the name or names of any underwriters, dealers or 
agents and the respective amounts of such Offered Securities underwritten or 
purchased by each of them, the initial public offering price of such Offered 
Securities and the proceeds to the Company from such sale, any discounts, 
commissions or other items constituting compensation from the Company and any 
discounts, commissions or concessions allowed or reallowed or paid to dealers 
and any securities exchanges on which such Offered Securities may be listed. 

   If underwriters are used in the sale of any Offered Securities, such 
Offered Securities will be acquired by the underwriters for their own account 
and may be resold from time to time in one or more transactions, including 
negotiated transactions, at a fixed public offering price or at varying 
prices determined at the time of sale. Such Offered Securities may be either 
offered to the public through underwriting syndicates represented by managing 
underwriters, or directly by underwriters. 

   Offered Securities may be sold directly by the Company or through agents 
designated by the Company from time to time. Unless otherwise indicated in 
the Prospectus Supplement, any such agent will be acting on a best efforts 
basis for the period of its appointment. 

   If so indicated in the Prospectus Supplement, the Company will authorize 
underwriters, dealers or agents to solicit offers by certain purchasers to 
purchase Offered Securities from the Company at the public offering price set 
forth in the Prospectus Supplement pursuant to delayed delivery contracts 
providing for payment and delivery on a specified date in the future. Such 
contracts will be subject only to those conditions set forth in the 
Prospectus Supplement. 

   Agents, dealers and underwriters may be entitled under agreements entered 
into with the Company to indemnification by the Company against certain civil 
liabilities, including liabilities under the Securities Act, or to 
contribution with respect to payments which the agents or underwriters may be 
required to make in respect thereof.

                                LEGAL MATTERS 

   Certain legal matters (including the validity of the Securities) will be 
passed upon for the Company by Steven A. McArthur, Senior Vice President and 
General Counsel of the Company and by Willkie Farr & Gallagher. As of August 
31, 1998, Mr. McArthur beneficially owned approximately 200,000 shares of 
Common Stock. 

                                   EXPERTS 

   The consolidated financial statements and financial statement schedules of 
the Company and its subsidiaries incorporated by reference in this 
Registration Statement by reference to the Company's Annual Report on Form 
10-K for the year ended December 31, 1997, have been audited by Deloitte & 
Touche LLP, independent auditors, as stated in their reports which are 
incorporated herein by reference, and have been so incorporated in reliance 
upon the reports of such firm given upon their authority as experts in 
accounting and auditing. 

   With respect to the Company's unaudited interim financial information for 
the periods ended March 31, 1998 and 1997 and June 30, 1998 and 1997, 
incorporated herein by reference, Deloitte & Touche LLP have applied limited 
procedures in accordance with professional standards for a review of such 
information. However, as stated in their reports included in the Company's 
Quarterly Reports on Form 10-Q for the quarters ended March 31, 1998 and June 
30, 1998, and incorporated by reference herein, they did not audit and they 
do not express an opinion on that interim financial information. Accordingly, 
the degree of reliance on their reports on such information should be 
restricted in light of the limited nature of the review procedures applied. 
Deloitte & Touche LLP are not subject to the liability provisions of Section 
11 of the Securities Act for their reports on the unaudited interim financial 
information because those reports are not "reports" or a "part" of the 
Registration Statement prepared or certified by an accountant within the 
meaning of Sections 7 and 11 of the Securities Act.
