MIDAMERICAN ENERGY HOLDINGS COMPANY

OVERVIEW

We are a United States-based global energy company. Our principal businesses are regulated electric and natural gas utilities, regulated interstate natural gas transmission and electric power generation. Our operations are organized and managed on seven distinct platforms which we refer to as: MidAmerican Energy, Northern Natural Gas, Kern River, CE Electric UK (which includes Northern Electric and Yorkshire Electricity), CalEnergy Generation-Domestic, CalEnergy Generation-Foreign and HomeServices. Through six of these platforms, we own and operate a combined electric and natural gas utility company in the United States, two natural gas pipeline companies in the United States, two electricity distribution companies in the United Kingdom and a diversified portfolio of domestic and international electric power projects. We also own the second largest residential real estate brokerage firm in the United States. The following is a chart of our operating platforms and the principal lines of business in which they are engaged:

Our principal subsidiaries generate, transmit, store, distribute and supply energy. Our electric and natural gas utility subsidiaries currently serve approximately 4.3 million electricity customers and approximately 653,000 natural gas customers. Our natural gas pipeline subsidiaries operate interstate natural gas transmission systems with approximately 17,500 miles of pipeline in operation and peak delivery capacity of 5.3 Bcf of natural gas per day. We have interests in 6,185 net owned megawatts of power generation facilities in operation and construction, including 4,618 net owned megawatts in facilities that are part of the regulated return asset base of our electric utility business (as further described in "Business--MidAmerican Energy--Electric Operations") and 1,567 net owned megawatts in non-utility power generation facilities. Substantially all of the non-utility power generation facilities have long-term contracts for the sale of energy and/or capacity from the facilities.

We have recently achieved significant growth in our asset base, while expanding and diversifying our underlying revenue and earnings base. In the past four years, we have consummated the four significant acquisitions described below.

In March 1999, our predecessor, CalEnergy Company, Inc., acquired a publicly traded company which owned the largest combined electric and gas utility in Iowa. The primary asset of this company consisted of the MidAmerican Energy platform.

1

In September 2001, we acquired the electricity distribution business of Yorkshire Power Group Ltd., or Yorkshire Electricity, which was one of the twelve original regional electric companies in the United Kingdom, and simultaneously sold the electricity and gas supply business of Northern Electric plc, or Northern Electric, to the former owner of Yorkshire Electricity.

In March 2002, we acquired Kern River Gas Transmission Company, or Kern River, which owns a 926-mile interstate natural gas pipeline extending from Wyoming to markets in California, Nevada and Utah and accesses natural gas supplies from large producing regions in the Rocky Mountains and Canada.

In August 2002, we acquired Northern Natural Gas Company, or Northern Natural Gas, for $928 million in cash (subject to adjustment for working capital). We used the proceeds from a $950 million investment in our subsidiary trust's preferred securities by Berkshire Hathaway Inc., or Berkshire Hathaway, to finance this acquisition.

Northern Natural Gas owns a 16,600-mile interstate natural gas pipeline extending from southwest Texas to the upper Midwest region of the United States with a design capacity of 4.4 Bcf of natural gas per day. Northern Natural Gas also operates three natural gas storage facilities and two liquefied natural gas peaking units with a total storage capacity of 59 Bcf and peak delivery capability of over 1.3 Bcf of natural gas per day. Northern Natural Gas accesses natural gas supply from many of the larger producing regions in North America, including the Rocky Mountains, Hugoton, Permian, Anadarko and Western Canadian basins. The pipeline system provides transportation and storage services to utilities, municipalities, other pipeline companies, gas marketers and industrial and commercial users.

Our revenues for the year ended December 31, 2001 were $5.3 billion and our total assets were $12.6 billion as of December 31, 2001. Our revenues for the nine months ended September 30, 2002 (which includes Kern River for the period from March 27, 2002 and Northern Natural Gas for the period from August 16, 2002) were $3.5 billion and our total assets were $17.0 billion as of September 30, 2002. As of September 30, 2002, the total consolidated assets of our four utility platforms, MidAmerican Energy, Northern Natural Gas, Kern River and CE Electric UK, aggregated approximately 82% of our total assets.

We are a privately owned company with publicly held fixed income securities. Since March 14, 2000, our sole shareholders have consisted of a private investor group comprised of Berkshire Hathaway, Walter Scott, Jr. and members of his family, David L. Sokol, our Chairman and Chief Executive Officer, and Gregory E. Abel, our President and Chief Operating Officer. Prior to that time, our common stock was publicly traded on the New York Stock Exchange.

STRATEGY

Our business strategy is focused upon the successful operation, management and growth of our diversified portfolio of energy assets and on the pursuit of strategic utility acquisitions and selected other investment opportunities, principally in the United States. As a privately owned company, we are able to focus on long-term risk-adjusted cash flow returns from our businesses. We seek to manage and operate our energy assets such that their cost structure makes us a low-cost provider of energy and energy services.

In order to implement this strategy, we plan to:

PURSUE OPERATING EFFICIENCIES AND INTERNAL INVESTMENT OPPORTUNITIES IN OUR BUSINESSES, WHILE MAINTAINING QUALITY AND RELIABILITY OF SERVICE. Our management philosophy emphasizes the efficient operation of our businesses through strict attention to the operational performance of our assets, continuous review and implementation of cost reduction initiatives and the active pursuit of opportunities to earn reasonable returns by making incremental capital investments within our existing operations. Following each of our utility acquisitions, we have implemented operational improvements and cost reductions that have enhanced asset performance and service reliability. These and other initiatives have helped us to pursue our goal of being a low-cost provider of energy and energy services to our customers and have strengthened our competitive position in the marketplace, while also increasing the returns on

2

our investments. In addition, we have worked closely and successfully with customers and with regulatory and legislative authorities to ensure that our business initiatives are consistent with our obligations to serve customers and with the requirements of the regulatory regimes under which we operate. We have identified and are proceeding with a number of significant capital investment opportunities that we believe offer attractive risk-adjusted returns. These opportunities include a $1.2 billion program to expand MidAmerican Energy's base of electric generation facilities in Iowa and a $1.2 billion expansion to approximately double the design delivery capacity of our Kern River pipeline by 2003, which we refer to as the 2003 Expansion Project.

GROW AND DIVERSIFY THROUGH ACQUISITIONS OF HIGH QUALITY REGULATED UTILITY BUSINESSES. We believe that well managed regulated utility businesses can provide a stable cash flow profile and a reasonable risk-adjusted equity return to their owners. Our acquisitions of Northern Electric in 1997 and MidAmerican Energy in 1999 provided us with specialized skills and expertise, particularly in operations and regulatory affairs, which have enhanced our competitive position and positioned us favorably for future growth in our targeted sectors. In the past fifteen months, we completed three acquisitions of utility operating companies, Yorkshire Electricity, Kern River and Northern Natural Gas, each of which has added substantially to our base of utility operating assets and cash flows. We believe that these acquisitions helped us achieve additional diversification of our utility business with respect to sources of cash flow, types of utility operations, geography and regulatory regimes.

CAPITALIZE ON CHANGE IN OUR INDUSTRY AND ON OUR SUPERIOR ACCESS TO CAPITAL IN ORDER TO MAKE ATTRACTIVE INVESTMENTS. The global energy markets, particularly those in the United States, are experiencing a period of significant change due to various factors, including the macroeconomic environment, fluctuating commodity prices, regulatory and legislative developments and financial restructurings by many market participants. We and our shareholders believe that such an environment provides opportunities for disciplined companies with access to investment capital to achieve reasonable risk-adjusted returns by acquiring high quality companies and assets at reasonable prices. Warren Buffett, Chairman of the Board and Chief Executive Officer of Berkshire Hathaway, has publicly stated that we are a core holding of Berkshire Hathaway and are expected to be its principal vehicle for investments in the energy sector. In 2002 to date, we completed two acquisitions of interstate natural gas transmission pipelines, which we funded with a majority of the proceeds of Berkshire Hathaway's investment in $1.273 billion of our trust preferred securities and $402 million of our zero coupon convertible preferred stock, all of which is subordinated to our senior indebtedness. We believe that our ability to successfully negotiate and complete these acquisitions was facilitated by our access to capital from Berkshire Hathaway and that there will continue to be opportunities in the current environment to make additional acquisitions that further enhance our business mix, risk profile, capitalization and investment returns.

ENHANCE OUR INVESTMENT GRADE CREDIT PROFILE AND THAT OF OUR SUBSIDIARIES. Our financing strategy is focused on capitalizing and managing our utility subsidiaries in a manner consistent with maintenance of strong credit ratings, thereby supporting our credit profile with more predictable underlying cash flows from these subsidiaries. This strategy is driven by our belief that strong credit ratings allow us to minimize our financing costs over the long term and to optimize our investment returns, while also retaining the financial flexibility to pursue attractive capital investment opportunities as and when they are available. Our strategy is to finance our operating subsidiaries with debt that in almost all cases is non-recourse to us, which has allowed us to reduce financing costs by taking advantage of the stable, investment grade characteristics of our subsidiaries' utility assets.

MAINTAIN PRUDENT FINANCIAL AND RISK MANAGEMENT POLICIES AND PRACTICES. Through our focus on regulated utility businesses, we strive to minimize the underlying risks of our portfolio of assets. Substantially all of our net owned megawatts in our non-utility power generation business have long-term (greater than one year) contracts for the sale of their energy and/or capacity, and substantially all of these assets are financed by non-recourse project finance debt. We seek to limit our exposure to movements in the commodity prices of energy products and are not a significant trader of energy commodities. Our activities in the marketing and supply of energy to customers outside of our regulated utility customer

3

base are not a material part of our business and are conducted pursuant to closely monitored risk management policies and practices that are intended to minimize our exposure to fluctuations in energy commodity prices and to counterparty credit risk. A core tenet of our acquisition and investment philosophy is that we will only pursue opportunities that meet our strict requirements for an acceptable risk profile and attractive potential cash flow returns. If we do not believe that such opportunities are available, we prefer to reduce our acquisition activities and focus on the optimization of our existing portfolio rather than pursue growth by accepting greater risks or inferior returns.

THE EXCHANGE OFFER

On October 4, 2002, we privately placed $200,000,000 aggregate principal amount of 4.625% senior notes due 2007 and $500,000,000 aggregate principal amount of 5.875% senior notes due 2012, which we refer to collectively as the original notes, in a transaction exempt from registration under the Securities Act. In connection with the private placement, we entered into a registration rights agreement, dated as of October 1, 2002, with the initial purchasers of the original notes. In the registration rights agreement, we agreed to offer our new 4.625% senior notes due 2007 and 5.875% senior notes due 2012, which will be registered under the Securities Act and which we refer to collectively as the exchange notes, in exchange for the applicable original notes. The exchange offer is intended to satisfy our obligations under the registration rights agreement. We also agreed to deliver this prospectus to the holders of the original notes. In this prospectus we refer to the original notes and the exchange notes as the notes. You should read the discussion under the headings "Summary--Terms of the Notes" and "Description of Notes" for information regarding the notes.

THE EXCHANGE OFFER..........   This is an offer to exchange $1,000 in
                               principal amount of exchange notes for each
                               $1,000 in principal amount of original notes. The
                               exchange notes are substantially identical to the
                               original notes, except that the exchange notes
                               will generally be freely transferable. We believe
                               that you can transfer the exchange notes without
                               complying with the registration and prospectus
                               delivery provisions of the Securities Act if you:

                               o  acquire the exchange notes in the ordinary
                                  course of your business;

                               o  are not and do not intend to become engaged
                                  in a distribution of the exchange notes;

                               o  are not an "affiliate" (within the meaning of
                                  the Securities Act) of ours;

                               o  are not a broker-dealer (within the meaning
                                  of the Securities Act) that acquires the
                                  original notes from us or our affiliates;

                               o  are not a broker-dealer (within the meaning of
                                  the Securities Act) that acquired the original
                                  notes in a transaction as part of its
                                  market-making or other trading activities.

                               If any of these conditions are not satisfied and
                               you transfer any exchange note without
                               delivering a proper prospectus or without
                               qualifying for a registration exemption, you may
                               incur liability under the Securities Act. See

                              agreed to use our reasonable best efforts to

                              original notes to be registered under the
                              Securities Act to permit resales. If we are not
                              in compliance with our obligations under the
                              registration rights agreement, liquidated damages
                              will accrue on the original notes in addition to
                              the interest that is otherwise due on the
                              original notes. If the exchange offer is
                              completed on the terms and within the time period
                              contemplated by this prospectus, no liquidated
                              damages will be payable on the notes. The
                              exchange notes will not contain any provisions
                              regarding the payment of liquidated damages. See

RISK FACTORS

An investment in the notes is subject to numerous risks, including, but not limited to, those set forth below. In addition to the information contained elsewhere in this prospectus, you should carefully consider the following risk factors when evaluating an investment in the notes, including participation in the exchange offer.

RISK ASSOCIATED WITH OUR CORPORATE AND FINANCIAL STRUCTURE

WE ARE A HOLDING COMPANY THAT DEPENDS ON DISTRIBUTIONS FROM OUR

SUBSIDIARIES AND JOINT VENTURES TO MEET OUR NEEDS.

We are a holding company and derive substantially all of our income and cash flow from our subsidiaries and joint ventures. We expect that future development and acquisition efforts will be similarly structured to involve operating subsidiaries and joint ventures. We are dependent on the earnings and cash flows of, and dividends, loans, advances or other distributions from, our subsidiaries and joint ventures to generate the funds necessary to meet our obligations, including the payment of principal of, or interest and premium, if any, on, the notes. All required payments on debt and preferred stock at subsidiary levels will be made before funds from our subsidiaries are available to us. The availability of distributions from such entities is also subject to:

o their earnings and capital requirements,

o the satisfaction of various covenants and conditions contained in financing documents by which they are bound or in their organizational documents, and

o in the case of our regulated utility subsidiaries, regulatory restrictions which restrict their ability to distribute profits to us.

Our subsidiaries and joint ventures are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the notes or to make any funds available, whether by dividends, loans or other payments, for payment of the notes, and do not guarantee the payment of interest or premium, if any, on or principal of the notes.

WE ARE SUBSTANTIALLY LEVERAGED AND THE NOTES ARE STRUCTURALLY SUBORDINATED

TO THE INDEBTEDNESS OF OUR SUBSIDIARIES.

Our substantial leverage level presents the risk that we might not generate sufficient cash to service our indebtedness, including the notes, or that our leveraged capital structure could limit our ability to finance future acquisitions, develop additional projects, compete effectively and operate successfully under adverse economic conditions. At September 30, 2002, our outstanding indebtedness was approximately $2.0 billion (excluding $2.1 billion in aggregate principal amount of our trust preferred securities, our guarantees and letters of credit in respect of subsidiary indebtedness aggregating approximately $235 million and our completion guarantee issued in favor of the lenders under Kern River's $875 million construction loan facility in connection with Kern River's 2003 Expansion Project). In addition, our subsidiaries have significant amounts of indebtedness. At September 30, 2002, our consolidated subsidiaries' and joint ventures' total outstanding indebtedness was approximately $7.1 billion, which does not include $453 million, representing our share of outstanding indebtedness of CE Generation, LLC, or CE Gen. This amount also does not include trade debt of our subsidiaries. The terms of the notes do not limit our ability or the ability of our subsidiaries or joint ventures to incur additional debt or issue additional preferred stock. Claims of creditors of our subsidiaries and joint ventures have priority over your claims with respect to the assets and earnings of our subsidiaries and joint ventures. In addition, the stock or assets of substantially all of our operating subsidiaries and joint ventures is directly or indirectly pledged to secure their financings and, therefore, may be unavailable as potential sources of repayment of the notes.

14

RISKS ASSOCIATED WITH OUR BUSINESS

OUR RECENT GROWTH HAS BEEN ACHIEVED, IN PART, THROUGH STRATEGIC

ACQUISITIONS, AND ADDITIONAL ACQUISITIONS MAY NOT BE SUCCESSFUL.

Because our industry is rapidly changing, there are opportunities for acquisitions of assets and businesses, as well as for business combinations. We investigate opportunities that may increase shareholder value and build on existing businesses. We have participated in the past and our security holders may assume that at any time we may be participating in bidding or other negotiations for such transactions. This participation may or may not result in a transaction for us. Any transaction that does take place may involve consideration in the form of cash, debt or equity securities.

In the past six years, we have completed several significant acquisitions, including the acquisitions of Northern Electric, Yorkshire Electricity, MidAmerican Energy, Kern River and Northern Natural Gas. We have successfully integrated Northern Electric, Yorkshire Electricity, MidAmerican Energy and Kern River. We closed on the Northern Natural Gas acquisition in August 2002 and are in the process of integrating its operations. We intend to continue to actively pursue acquisitions in the energy industry to complement and diversify our existing business for the foreseeable future.

The successful integration of Northern Natural Gas and any businesses we may acquire in the future will entail numerous risks, including, among others, the risk of diverting management's attention from day-to-day operations, 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. 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.

In addition, it has been publicly reported over the past year that many of the participants in the United States energy industry, including the prior owners of Kern River and Northern Natural Gas and potentially including other industry participants from whom we may choose to purchase additional businesses in the future, have recently had or may have liquidity, creditworthiness and other financial difficulties. As a consequence, there can be no assurance that any such sellers will not enter into bankruptcy or insolvency proceedings or that they will otherwise be able, required or willing to perform on their indemnification obligations to us if we should elect to pursue any such claims we may have against any of them under our acquisition agreements in the future. If our due diligence efforts were or are unsuccessful in identifying and analyzing all material liabilities relating to acquired companies and if there were to be any material undisclosed liabilities, or if there were to be other unexpected consequences from any such bankruptcy or insolvency proceeding, such as a successful challenge as to whether the prices paid by us constituted reasonably equivalent value within the meaning of the relevant bankruptcy laws, then any such bankruptcy or insolvency, or failure by any of these sellers to perform their indemnification obligations to us, could have a material adverse effect on our business, financial condition, results of operations and the market prices and rates for our securities.

We cannot assure you that future acquisitions, if any, or any related integration efforts will be successful, or that our ability to repay the notes will not be adversely affected by any future acquisitions.

WE ARE ACTIVELY PURSUING, DEVELOPING AND CONSTRUCTING NEW OR EXPANDED FACILITIES, THE COMPLETION AND EXPECTED COST OF WHICH IS SUBJECT TO SIGNIFICANT RISK.

Through our operating subsidiaries, we are continuing to develop, construct, own and operate new or expanded facilities, including Kern River's 2003 Expansion Project, the Zinc Recovery Project and two planned electric generating plants in Iowa, and in the future we expect to pursue the development, construction, ownership and operation of additional new or expanded 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, including any future projects, is subject to substantial risk and may expose us to significant costs. We cannot assure you that our development or construction efforts on any particular project, or our efforts generally, will be successful.

15

Also, a proposed expansion or project may cost more than planned to complete, and such excess costs, if related to a regulated asset and found to be imprudent, may not be recoverable in rates. The inability to successfully and timely complete a project or avoid unexpected costs may require us to perform under guarantees (such as the Kern River completion guarantee), and the inability to avoid unsuccessful projects or to recover any excess costs may materially affect our ability to service our obligations under the notes. Our Kern River completion guarantee also contains a potential acceleration event based on our credit ratings and certain other potential acceleration events which are more fully described elsewhere in this prospectus.

OUR SUBSIDIARIES ARE SUBJECT TO CERTAIN OPERATING UNCERTAINTIES WHICH MAY

ADVERSELY AFFECT REVENUES, EXPENSES OR DISTRIBUTIONS.

The operation of complex electric and gas utility (including transmission and distribution systems), pipeline or power generating facilities involves many operating uncertainties and events beyond our control. Operating risks include the breakdown or failure of power generation equipment, compressors, pipelines, transmission and distribution lines or other equipment or processes, fuel interruption, performance below expected levels of output, capacity or efficiency, operator error and catastrophic events such as severe storms, fires, earthquakes or explosions. A casualty occurrence might result in injury or loss of life, extensive property damage or environmental damage. Revenues, expenses and distributions may also be adversely affected by general economic, business, regulatory and weather conditions. The realization of any of these risks could significantly reduce or eliminate our affiliates' revenues or significantly increase our affiliates' expenses, thereby adversely affecting the ability to receive distributions from subsidiaries and joint ventures.

We currently possess property, business interruption, catastrophic and general liability insurance, but proceeds from such insurance coverage may not be adequate for all liabilities incurred, lost revenue or increased expenses. Moreover, such insurance may not be available in the future at commercially reasonable costs and on commercially reasonable terms. Changes in the insurance markets subsequent to the September 11, 2001 terrorist attacks have made it more difficult for us to obtain certain types of coverage. There can be no assurance that we will be able to obtain the levels or types of insurance we would otherwise have obtained prior to these market changes or that the insurance coverage we do obtain will not contain large deductibles or fail to cover certain hazards or that it will otherwise cover all potential losses.

ACTS OF SABOTAGE AND TERRORISM AIMED AT OUR FACILITIES COULD ADVERSELY

EFFECT OUR BUSINESS.

Since the September 11, 2001 terrorist attacks, the United States government has issued warnings that energy assets, specifically our nation's pipeline and utility infrastructure, may be the future targets of terrorist organizations. These developments have subjected our operations to increased risks. Any future acts of sabotage or terrorism aimed at our facilities, or those of our customers, could have a material adverse effect on our business, financial condition, results of operations and ability to service the notes. Any resulting acts of war or the threat of war as a result of such terrorist attacks could adversely affect the economy and energy consumption. Instability in the financial markets as a result of terrorism or war could also materially adversely affect our ability to raise capital.

WE ARE SUBJECT TO COMPREHENSIVE ENERGY REGULATION AND CHANGES IN REGULATION AND RATES MAY ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION, RESULTS OF OPERATIONS AND ABILITY TO SERVICE THE NOTES.

We are subject to comprehensive governmental regulation, including regulation in the United States by various federal, state and local regulatory agencies, regulation in the United Kingdom and regulation in the Philippines, all of which significantly influences our operating environment, our rates, our capital structure, our costs and our ability to recover our costs from customers. These regulatory agencies include, among others, the Federal Energy Regulatory Commission, or the FERC, the Environmental Protection Agency, or the EPA, the Nuclear Regulatory Commission, the United States Department of Transportation, the Iowa Utilities Board, or the IUB, the Illinois Commerce Commission, other state utility boards, numerous local agencies, the Gas and Electricity Markets Authority, or GEMA, which in discharging certain of its powers acts through its staff within the Office of Gas and Electricity Markets, or Ofgem, in

16

the United Kingdom, and various other governmental agencies in the United Kingdom and the Philippines. The FERC has jurisdiction over, among other things, wholesale rates for electric transmission service and electric energy sold in interstate commerce, interstate natural gas transportation and storage rates, the siting and construction of interstate natural gas transportation facilities and certain other activities of our utility subsidiaries. United States federal, state and local agencies also have jurisdiction over many of our other activities. The utility commissions in the states where our utility subsidiaries operate regulate many aspects of our utility operations including siting and construction of facilities, customer service and the rates that we can charge customers. The revenues of our United Kingdom distribution businesses are subject to review and adjustment by GEMA and many other aspects of our subsidiaries' United Kingdom operations are subject to the jurisdiction of GEMA and other regulators and agencies in the United Kingdom.

The structure of federal and state energy regulation is currently undergoing change and has in the past, and may in the future, be the subject of various challenges, initiatives and restructuring proposals by policy makers, utilities and other industry participants. In addition to Congressional initiatives, 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. The implementation of regulatory changes in response to such challenges, initiatives and restructuring proposals could result in the imposition of more comprehensive or stringent requirements on us or our subsidiaries or other industry participants, which would result in increased compliance costs and could have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

We are unable to predict the impact on our operating results from the future regulatory activities of any of these agencies or the Securities and Exchange Commission, or SEC, under the Public Utility Holding Company Act of 1935, as amended, or PUHCA. Changes in regulations or the imposition of additional regulations could have a material adverse impact on our results of operations. Recent developments, events and uncertainties which have impacted or could impact our businesses are described below.

On July 31, 2002, the FERC issued a notice of proposed rulemaking with respect to Standard Market Design for the electric industry. The FERC has characterized the proposal as portending "sweeping changes" to the use and expansion of the interstate transmission and wholesale bulk power systems in the United States. The proposal includes numerous proposed changes to the current regulation of transmission and generation facilities designed "to promote economic efficiency" and replace the "obsolete patchwork we have today," according to the FERC Chairman. The final rule, if adopted as currently proposed, would require all public utilities operating transmission facilities subject to the FERC jurisdiction to file revised open access transmission tariffs that would require changes to the basic services these public utilities currently provide. The proposed rule may impact the pricing of MidAmerican Energy's electricity and transmission products. The FERC does not envision that a final rule will be fully implemented until September 30, 2004. We are still evaluating the proposed rule, and we believe that the final rule could vary considerably from the initial proposal. Accordingly, we are presently unable to quantify the likely impact of the proposed rule on us.

The state utility regulatory environment has to date, in general, given MidAmerican Energy an exclusive right to serve retail electricity customers within its primary service territory in Iowa and, in turn, the obligation to provide electric service to those customers. There can be no assurance that there will not be a change in legislation or regulation in Iowa or in any of the other states in which we operate to allow retail competition in MidAmerican Energy's service territory.

Because our Kern River and Northern Natural Gas pipeline systems are interstate natural gas pipelines subject to regulation as natural gas companies under the Natural Gas Act, as amended, the rates we can charge our customers and other terms and conditions of service are subject to review by the FERC and the possibility of modification in periodic rate proceedings or at any time in response to a complaint proceeding initiated by a customer or on the FERC's own initiative. The rates we can charge are required to be just and reasonable. The objective of the rate setting process is to allow us to recover our costs to

17

construct, own, operate and maintain our pipelines which are actually and prudently incurred and to afford us an opportunity to earn a reasonable rate of return. Under the terms of our transportation service contracts and in accordance with the FERC's rate making principles, our current maximum tariff rates are designed to recover costs included in our pipeline systems' regulatory cost of service that are associated with the construction and operation of our pipeline systems that are actually, reasonably and prudently incurred. All costs incurred may not be recoverable through existing or future rates. Failure to recover material costs may have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

Revenue from Northern Electric's and Yorkshire Electricity's distribution business is controlled by a distribution price control formula which determines the maximum average price per unit of electricity that a distribution network operator in Great Britain may charge. The distribution price control formula is expected to have a five-year duration and is subject to review by the British regulatory body for the energy sector, GEMA, at the end of each five-year period and at other times in the discretion of GEMA. At each review, GEMA can propose adjustments to the distribution price control formula. In December 1999, a review resulted in a reduction in allowed revenue of 24% for Northern Electric's distribution business and 23% for Yorkshire Electricity's distribution business, in real terms, with effect from and after April 1, 2000. The next review of the distribution price control formula is expected to become effective in April 2005. Any further price reviews by GEMA, including those it may elect to conduct at any time in its discretion, may have a material adverse effect on our results of operations.

The Philippine Congress has passed the Electric Power Reform Act of 2001, which is aimed at restructuring the power industry, including privatization of the National Power Corporation, or the NPC, and introduction of a competitive electricity market, among other initiatives. The implementation of the bill may have an adverse impact on our future operations in the Philippines and the Philippines power industry as a whole.

WE ARE SUBJECT TO ENVIRONMENTAL, SAFETY AND OTHER LAWS AND REGULATIONS

WHICH MAY ADVERSELY IMPACT US.

Through our subsidiaries and joint ventures, we are subject to a number of environmental, safety and other laws and regulations affecting many aspects of our present and future operations, both domestic and foreign, including air emissions, water quality, wastewater discharges, solid wastes, hazardous substances and safety matters. We may incur substantial costs and liabilities in connection with our operations as a result of these regulations. In particular, the cost of future compliance with federal, state and local clean air laws, such as those that require certain generators, including some of our subsidiaries' electric generating facilities, to limit nitrogen oxide emissions and potential other pollutants, may require us to make significant capital expenditures which may not be recoverable through future rates. In addition, these costs and liabilities may include those relating to claims for damages to property and persons resulting from our operations. The implementation of regulatory changes imposing more comprehensive or stringent requirements on us, to the extent such changes would result in increased compliance costs or additional operating restrictions, could have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

In addition, regulatory compliance for existing facilities and 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 value if projects cannot function as planned due to changing regulatory requirements or local opposition.

Potential pipeline safety legislation and an increase in public expectations on pipeline safety may also require replacement of some of our pipeline segments, addition of monitoring equipment, and more frequent inspection or testing of our pipeline facilities. These requirements coupled with increases in state and federal agency oversight, if adopted, would necessitate additional testing and reporting which may result in higher operating costs and/or capital costs. Our FERC-approved tariffs or competition from other natural gas sources may not allow us to recover these increased costs of compliance.

18

In addition to operational standards, environmental laws also impose obligations to clean up or remediate contaminated properties or to pay for the cost of such remediation, often upon parties that did not actually cause the contamination. Accordingly, we may become liable, either contractually or by operation of law, for remediation costs even if the contaminated property is not presently owned or operated by us, or if the contamination was caused by third parties during or prior to our ownership or operation of the property. Given the nature of the past industrial operations conducted by us and others at our properties, there can be no assurance that all potential instances of soil or groundwater contamination have been identified, even for those properties where an environmental site assessment or other investigation has been conducted. Although we have accrued reserves for our known remediation liabilities, future events, such as changes in existing laws or policies or their enforcement, or the discovery of currently unknown contamination, may give rise to additional remediation liabilities which may be material.

Any failure to recover increased environmental or safety costs incurred by us may have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

INCREASED COMPETITION RESULTING FROM LEGISLATIVE, REGULATORY AND RESTRUCTURING EFFORTS COULD HAVE A SIGNIFICANT FINANCIAL IMPACT ON US AND OUR UTILITY SUBSIDIARIES AND CONSEQUENTLY DECREASE OUR REVENUE.

The energy market continues to move towards a competitive environment and is characterized by numerous strong and capable competitors, many of which have more extensive operating experience and greater financial resources than we and our subsidiaries. Retail competition and the unbundling of regulated energy and gas service could have a significant adverse financial impact on us and our subsidiaries due to an impairment of assets, a loss of customers, lower profit margins and/or increased costs of capital. The total impacts of restructuring may have a significant financial impact on our financial position, results of operations and cash flows. We cannot predict when we will be subject to changes in legislation or regulation, nor can we predict the impacts of these changes on our financial position, results of operations or cash flows.

The generation segment of the electric industry has been and will be significantly impacted by competition. The introduction of competition in the wholesale market has resulted in a proliferation of power marketers and a substantial increase in market activity. Many of these marketers have experienced financial difficulties and the market continues to be volatile.

As retail competition continues to evolve, margins will be pressured by competition from other utilities, power marketers and self-generation. Many states and the federal government are implementing or considering regulatory initiatives that would increase access to electric utilities' transmission and distribution systems for independent power producers, utilities, power marketers and electricity customers. Although the recent and anticipated changes in the United States electric utility industry may create opportunities, they will also create additional challenges and risks for utilities. Competition will put pressure on margins for traditional electric services. Illinois recently enacted a law that provides for full retail customer choice in 2002. While introduction of retail competition in Iowa is not presently expected, depending upon the terms of any such legislation, if introduced it could have a material adverse effect on us. These types of restructurings and other industry restructuring efforts could materially impact our results of operations in a manner which is difficult to predict, since such efforts will depend on the terms and timing of such restructuring.

As a result of the FERC orders, including Order 636, the FERC's policies favoring competition in gas markets, the expansion of existing pipelines and the construction of new pipelines, the interstate pipeline industry has begun to experience some failure to renew, or turn back, of firm capacity, as existing transportation service agreements expire and are terminated. Local distribution companies and end-use customers have more choices in the new, more competitive environment and may be able to obtain service from more than one pipeline to fulfill their natural gas delivery requirements. If a pipeline experiences capacity turn back and is unable to remarket the capacity, the pipeline or its remaining customers may have to bear the costs associated with the capacity that is turned back. Any new pipelines that are constructed could compete with our pipeline subsidiaries for customers' service needs. Increased

19

competition could reduce the volumes of gas transported by our pipeline subsidiaries or, in cases where they do not have long-term fixed rate contracts, could force our pipeline subsidiaries to lower their rates to meet competition. This could adversely affect our pipeline subsidiaries' financial results.

A SIGNIFICANT DECREASE IN DEMAND FOR NATURAL GAS IN THE MARKETS SERVED BY OUR SUBSIDIARIES' PIPELINE AND DISTRIBUTION SYSTEMS WOULD SIGNIFICANTLY DECREASE OUR REVENUE AND THEREBY ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION, RESULTS OF OPERATIONS AND ABILITY TO SERVICE THE NOTES.

A sustained decrease in demand for natural gas in the markets served by our subsidiaries' pipeline and distribution systems would significantly reduce our revenues. Factors that could lead to a decrease in market demand include:

o a recession or other adverse economic condition that results in a lower level of economic activity or reduced spending by consumers on natural gas;

o an increase in the market price of natural gas or a decrease in the price of other competing forms of energy, including electricity, coal and fuel oil;

o higher fuel taxes or other governmental or regulatory actions that increase, directly or indirectly, the cost of natural gas or that limit the use of natural gas;

o a shift by consumers to more fuel-efficient or alternative fuel machinery or an improvement in fuel economy, whether as a result of technological advances by manufacturers, pending legislation proposing to mandate higher fuel economy, or otherwise; and

o a shift by our pipeline and distribution customers to the use of alternate fuels, such as fuel oil, due to price differentials or other incentives.

FAILURE OF OUR SIGNIFICANT POWER PURCHASERS AND PIPELINE CUSTOMERS TO PAY

AMOUNTS DUE UNDER THEIR CONTRACTS COULD REDUCE OUR REVENUES MATERIALLY.

Our subsidiaries' non-utility generating facilities and both of our pipeline subsidiaries are dependent upon a relatively small number of customers for a significant portion of their revenues. As a result, our profitability and ability to make payments under the notes generally will depend upon the continued financial performance and creditworthiness of these customers. Accordingly, failure of one or more of our most significant customers to pay for contracted electric generating capacity or pipeline capacity reservation charges, for reasons related to financial distress or otherwise, could reduce our revenues materially if we were not able to make adequate alternate arrangements and therefore could have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

OUR PIPELINE SUBSIDIARIES MAY NOT BE ABLE TO MAINTAIN OR REPLACE LONG-TERM GAS TRANSPORTATION SERVICE AGREEMENTS AT FAVORABLE RATES AS EXISTING CONTRACTS EXPIRE.

Our business, financial condition, results of operations and ability to service the notes are dependent in significant part on the ability of Kern River and Northern Natural Gas to maintain long-term transportation service agreements with customers subject to favorable transportation rates.

Many of our long-term transportation service agreements will expire before the maturity of the notes. Upon expiration, existing customers may elect not to extend their contracts at rates favorable to our subsidiaries or on a long-term basis, or at all. Our pipeline subsidiaries may also be unable to obtain favorable replacement agreements with other customers. The extension or replacement of the existing long-term contracts depends on a number of factors beyond our control, including:

o the availability of economically deliverable natural gas for transport through our pipeline system, including in particular continued availability of adequate supplies from the Rocky Mountains, Hugoton, Permian, Anadarko and Western Canadian supply basins currently accessible to our pipeline subsidiaries;

o existing competition to deliver natural gas to the upper Midwest and southern California;

20

o new pipelines or expansions potentially serving the same markets as our pipelines;

o the growth in demand for natural gas in the upper Midwest and southern California;

o whether transportation of natural gas pursuant to long-term contracts continues to be market practice; and

o whether our business strategy, including our expansion strategy, continues to be successful.

Any failure to extend or replace a significant portion of these contracts may have a material adverse effect on our business, financial condition, results of operations and ability to service the notes.

OUR UTILITY AND NON-UTILITY BUSINESSES ARE SUBJECT TO MARKET AND CREDIT

RISK.

We are exposed to market and credit risks in our subsidiaries' generation, retail distribution and pipeline operations. Specifically, such risks include commodity price changes, market supply shortages, interest rate changes and counterparty default. In Iowa, MidAmerican Energy does not have an ability to pass through fuel price increases in its rates (an energy adjustment clause), so any significant increase in fuel costs or purchased power costs could have a negative impact on MidAmerican Energy. To minimize these risks, we require collateral to be posted if the creditworthiness of counterparties deteriorates below established levels and enter into financial derivative instrument contracts to hedge purchase and sale commitments, fuel requirements and inventories of natural gas, electricity, coal and emission allowances. However, financial derivative instrument contracts do not eliminate the risk. The impact of these risks could result in our inability to fulfill contractual obligations, significantly higher energy or fuel costs relative to corresponding sales contracts or increased interest expense.

WE HAVE SIGNIFICANT OPERATIONS OUTSIDE THE UNITED STATES WHICH MAY BE SUBJECT TO INCREASED RISK BECAUSE OF THE ECONOMIC OR POLITICAL CONDITIONS OF THE COUNTRY IN WHICH THEY OPERATE.

We have a number of operations outside of the United States. The acquisition, ownership and operation of businesses outside the United States entail significant political and financial risks (including, without limitation, uncertainties associated with privatization efforts, inflation, 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 material impairment of the value of the business being operated, which we may not be capable of fully insuring against. The risk of doing business outside of the United States could be greater than in the United States because of specific economic or political conditions of each country. The uncertainty of the legal environment in certain foreign countries in which we operate or may acquire projects or businesses could make it more difficult for us to enforce our rights under agreements relating to such projects or businesses. In addition, the laws and regulations of certain countries may limit our ability to hold a majority interest in some of the projects or businesses that we may 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 restrict distributions to foreign investors. Although we may structure certain project revenue and other 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 we will be able to obtain sufficient dollars or other hard currency or that available dollars will be allocated to pay such obligations.

Our international projects may be subject to the risk of being delayed, suspended or terminated by the applicable foreign governments or may be subject to the risk of contract abrogation, expropriations or other uncertainties resulting from changes in government policy or personnel or changes in general political or economic conditions affecting the country. In this regard, reference is made to the substantial uncertainties associated with one of our non-utility power projects in the Philippines, which is referred to as the Casecnan Project, where certain payments under the primary project agreement are currently not being made by the government of the Philippines and are presently the subject of international arbitration. Specifically, under the terms of a Casecnan Project agreement between CE Casecnan Water and Energy Company, Inc., or CE Casecnan, and the Philippine National Irrigation Administration, or NIA, NIA has the option of timely reimbursing CE Casecnan directly for certain taxes CE Casecnan has

21

paid. If NIA does not so reimburse CE Casecnan, the taxes paid by CE Casecnan result in an increase in the Water Delivery Fee under the Casecnan Project agreement. The payment of certain other taxes by CE Casecnan results automatically in an increase in the Water Delivery Fee. As of June 30, 2002, CE Casecnan has paid approximately $54.4 million in taxes which as a result of the foregoing provisions had resulted in an increase in the Water Delivery Fee. NIA has failed to pay the portion of the Water Delivery Fee each month which relates to the payment of these taxes by CE Casecnan. As a result of this non-payment, on August 19, 2002, CE Casecnan filed a Request for Arbitration against NIA, seeking payment of such portion of the Water Delivery Fee and enforcement of the relevant provision of the Casecnan Project agreement going forward. The arbitration will be conducted in accordance with the rules of the International Chamber of Commerce.

WE FACE EXCHANGE RATE RISK.

Payments from some of our foreign investments, including without limitation Northern Electric and Yorkshire Electricity, are made in a foreign currency and any dividends or distributions of earnings in respect of such investments 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 we 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.

RISKS ASSOCIATED WITH THE EXCHANGE OFFER

YOU MAY NOT BE ABLE TO SELL YOUR ORIGINAL NOTES IF YOU DO NOT EXCHANGE

THEM FOR REGISTERED EXCHANGE NOTES IN THE EXCHANGE OFFER.

If you do not exchange your original notes for exchange notes in the exchange offer, your original notes will continue to be subject to the restrictions on transfer as stated in the legends on the original notes. In general, you may not offer, sell or otherwise transfer the original notes in the United States unless they are:

o registered under the Securities Act;

o offered or sold under an exemption from the Securities Act and applicable state securities laws; or

o offered or sold in a transaction not subject to the Securities Act and applicable state securities laws.

We do not currently anticipate that we will register the original notes under the Securities Act. Except for limited instances involving the initial purchasers or holders of original notes who are not eligible to participate in the exchange offer or who receive freely transferable exchange notes in the exchange offer, we will not be under any obligation to register the original notes under the Securities Act under the registration rights agreement or otherwise. Also, if the exchange offer is completed on the terms and within the time period contemplated by this prospectus, no liquidated damages will be payable on your original notes.

YOUR ABILITY TO SELL YOUR ORIGINAL NOTES MAY BE SIGNIFICANTLY MORE LIMITED AND THE PRICE AT WHICH YOU MAY BE ABLE TO SELL YOUR ORIGINAL NOTES MAY BE SIGNIFICANTLY LOWER IF YOU DO NOT EXCHANGE THEM FOR REGISTERED EXCHANGE NOTES IN THE EXCHANGE OFFER.

To the extent that original notes are exchanged in the exchange offer, the trading market for the original notes that remain outstanding may be significantly more limited. As a result, the liquidity of the original notes not tendered for exchange could be adversely affected. The extent of the market for original notes would depend upon a number of factors, including the number of holders of original notes remaining outstanding and the interest of securities firms in maintaining a market in the original notes. An issue of securities with a similar outstanding market value available for trading, which is called the "float," may command a lower price than would be comparable to an issue of securities with a greater float. As a result, the market price for original notes that are not exchanged in the exchange offer may be affected adversely to the extent that original notes exchanged in the exchange offer reduce the float. The reduced float also may make the trading price of the original notes that are not exchanged more volatile.

22

THERE ARE STATE SECURITIES LAW RESTRICTIONS ON THE RESALE OF THE EXCHANGE

NOTES.

In order to comply with the securities laws of certain jurisdictions, the exchange notes may not be offered or resold by any holder unless they have been registered or qualified for sale in such jurisdictions or an exemption from registration or qualification is available and the requirements of such exemption have been satisfied. We do not currently intend to register or qualify the resale of the exchange notes in any such jurisdictions. However, an exemption is generally available for sales to registered broker-dealers and certain institutional buyers. Other exemptions under applicable state securities laws may also be available.

WE WILL NOT ACCEPT YOUR ORIGINAL NOTES FOR EXCHANGE IF YOU FAIL TO FOLLOW THE EXCHANGE OFFER PROCEDURES AND, AS A RESULT, YOUR ORIGINAL NOTES WILL CONTINUE TO BE SUBJECT TO EXISTING TRANSFER RESTRICTIONS AND YOU MAY NOT BE ABLE TO SELL YOUR ORIGINAL NOTES.

We will issue exchange notes as part of the exchange offer only after a timely receipt of your original notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, if you want to tender your original notes, please allow sufficient time to ensure timely delivery. If we do not receive your original notes, letter of transmittal and other required documents by the expiration date of the exchange offer, we will not accept your original notes for exchange. We are under no duty to give notification of defects or irregularities with respect to the tenders of original notes for exchange. If there are defects or irregularities with respect to your tender of original notes, we will not accept your original notes for exchange. See "The Exchange Offer."

FORWARD-LOOKING STATEMENTS

This prospectus contains statements that do not directly or exclusively relate to historical facts. These statements are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. You can typically identify forward-looking statements by the use of forward-looking words, such as "may", "will", "could", "project", "believe", "anticipate", "expect", "estimate", "continue", "potential", "plan", "forecast" and similar terms. These statements represent our intentions, plans, expectations and beliefs and are subject to risks, uncertainties and other factors. Many of these factors are outside our control and could cause actual results to differ materially from such forward-looking statements. These factors include, among others:

o general economic and business conditions in the jurisdictions in which our facilities are located;

o governmental, statutory, regulatory or administrative initiatives or ratemaking actions affecting us or the electric or gas utility, pipeline or power generation industries;

o weather effects on sales and revenues;

o general industry trends;

o increased competition in the power generation, electric utility or pipeline industries;

o fuel and power costs and availability;

o continued availability of accessible gas reserves;

o changes in business strategy, development plans or customer or vendor relationships;

o availability, term and deployment of capital;

o availability of qualified personnel;

o risks relating to nuclear generation;

o financial or regulatory accounting principles or policies imposed by the Public Company Accounting Oversight Board, the Financial Accounting Standards Board, the SEC, the FERC and similar entities with regulatory oversight; and

o other business or investment considerations that may be disclosed from time to time in our SEC filings or in other publicly disseminated written documents.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The foregoing review of factors should not be construed as exclusive.

24

USE OF PROCEEDS

We will not receive any proceeds from the issuance of the exchange notes in the exchange offer. The exchange notes will evidence the same debt as the original notes tendered in exchange for exchange notes. Accordingly, the issuance of the exchange notes will not result in any change in our indebtedness.

The net proceeds of the private placement of the original notes were approximately $694 million after deducting the initial purchasers' discount and expenses related to the offering of the original notes. We used these net proceeds for general corporate purposes, including to repay our short term debt in the amount of $167 million; and to make up to $300 million of funds available for an equity contribution to Kern River, to be applied by Kern River to fund a portion of the costs of its 2003 Expansion Project.

We also used the net proceeds to make an equity contribution of $150 million to Northern Natural Gas and a loan of $300 million to Northern Natural Gas. Northern Natural Gas used these amounts to repay an equal amount of its outstanding indebtedness under its bank credit agreement. Northern Natural Gas repaid the loan to us from the proceeds of its offering of $300 million of 5.375% Senior Notes due 2012, which was completed on October 15, 2002.

25

THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER

On October 4, 2002, we privately placed the original notes in a transaction exempt from registration under the Securities Act. Accordingly, the original notes may not be reoffered, resold or otherwise transferred in the United States unless so registered or unless an exemption from the Securities Act registration requirements is available. Pursuant to a registration rights agreement with the initial purchasers of the original notes, we agreed, for the benefit of holders of the notes, to:

o prepare and file an exchange offer registration statement with the SEC with respect to a registered offer to exchange each series of original notes for a series of exchange notes that will be issued under the same indenture, in the same aggregate principal amount as and with terms that are substantially identical in all material respects to the original notes except that they will not contain terms with respect to transfer restrictions;

o use our reasonable best efforts to cause the exchange offer registration statement to become effective under the Securities Act within 270 days after the date on which we issued the original notes; and

o promptly after the exchange offer registration statement is declared effective, offer the exchange notes in exchange for surrender of the original notes.

We will be entitled to consummate the exchange offer on the expiration date provided that we have accepted all original notes previously validly tendered in accordance with the terms set forth in this prospectus and the applicable letter of transmittal.

In addition, under certain circumstances described below, we may be required to file a shelf registration statement to cover resales of the notes.

If we do not comply with certain of our obligations under the registration rights agreement, we must pay liquidated damages on the original notes in addition to the interest that is otherwise due on the notes. See "--Liquidated Damages." The purpose of the exchange offer is to fulfill our obligations with respect to the registration rights agreement.

If you are a broker-dealer that receives exchange notes for its own account in exchange for original notes, where you acquired such original notes as a result of market-making activities or other trading activities, you must acknowledge that you will deliver a prospectus in connection with any resale of such exchange notes. See "Plan of Distribution."

TERMS OF THE EXCHANGE

Upon the terms and subject to the conditions contained in this prospectus and in the letters of transmittal that accompany this prospectus, with respect to each series of original notes, we are offering to exchange $1,000 in principal amount of exchange notes for each $1,000 in principal amount of original notes. The terms of the exchange notes are substantially identical to the terms of the original notes for which they may be exchanged in the exchange offer, except that the exchange notes will generally be freely transferrable. The exchange notes will evidence the same debt as the original notes and will be entitled to the benefits of the indenture. Any original notes of a series that remain outstanding after the consummation of the exchange offer, together with all exchange notes of that series issued in connection with the exchange offer, will be treated as a single class of securities under the indenture. See "Description of Notes."

The exchange offer is not conditioned on any minimum aggregate principal amount of original notes being tendered for exchange.

Based on existing interpretations of the Securities Act by the staff of the SEC set forth in several no-action letters to third parties, and subject to the immediately following sentence, we believe that you may offer for resale, resell and otherwise transfer the exchange notes without further compliance with the

26

registration and prospectus delivery provisions of the Securities Act. However, if you are an "affiliate" (within the meaning of the Securities Act) of ours or you intend to participate in the exchange offer for the purpose of distributing the exchange notes or you are a broker-dealer (within the meaning of the Securities Act) that acquired notes in a transaction other than as part of its market-making or other trading activities and who has arranged or has an understanding with any person to participate in the distribution of the exchange notes, you:

(1) will not be able to rely on the interpretations by the staff of the SEC set forth in the above-mentioned no-action letters;

(2) will not be able to tender your notes in the exchange offer; and

(3) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of your notes unless such sale or transfer is made pursuant to an exemption from such requirements.

Subject to exceptions for certain holders, to participate in the exchange offer you will be required to represent to us at the time of the consummation of the exchange offer, among other things, that (1) you are not an affiliate of ours; (2) any exchange notes to be received by you will be acquired in the ordinary course of your business; and (3) at the time of commencement of the exchange offer, you have no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the notes. In addition, in connection with any resales of exchange notes, any broker-dealer who acquired exchange notes for its own account as a result of market-making activities or other trading activities must deliver a prospectus meeting the requirements of the Securities Act. The SEC has taken the position that such a broker-dealer may fulfill its prospectus delivery requirements with respect to the exchange notes (other than a resale of an unsold allotment from the initial sale of the original notes) with this prospectus. Under the registration rights agreement, we are required to allow a broker-dealer and other persons with similar prospectus delivery requirements, if any, to use this prospectus connection with the resale of such exchange notes for a period of time not less than 120 days following the consummation of the exchange offer. If you are a broker-dealer that receives exchange notes for its own account in exchange for original notes, where you acquired such original notes as a result of market-making activities or other trading activities, you must acknowledge that you will deliver a prospectus in connection with any resale of such exchange notes. See "Plan of Distribution."

You will not be required to pay brokerage commissions or fees or, subject to the instructions in the applicable letter of transmittal, transfer taxes relating to your exchange of original notes for exchange notes in the exchange offer.

SHELF REGISTRATION STATEMENT

If:

o we are not permitted to effect the exchange offer because of any change in law or in applicable interpretations of such law by the staff of the SEC;

o the exchange offer is not consummated by the 40th day after the date on which the exchange offer registration statement was declared effective;

o any of the initial purchasers of the original notes so requests with respect to the original notes not eligible to be exchanged for exchange notes in the exchange offer and held by it following the consummation of exchange offer;

o any holder of notes (other than a broker-dealer electing to exchange original notes acquired for its own account as a result of market-making or other trading activities for exchange securities) is not eligible to participate in the exchange offer and any such holder so requests for any reason other than the failure by such holder to make a timely and valid tender in accordance with the terms of exchange offer; or

o any holder of notes (other than a broker-dealer electing to exchange original notes acquired for its own account as a result of market-making or other trading activities for exchange securities)

27

participates in the exchange offer but does not receive freely tradeable exchange notes on the date of the exchange and any such holder so requests for any reason other than the failure by such holder to make a timely and valid tender in accordance with the terms of exchange offer,

we will:

o as promptly as practicable prepare and file with the SEC a shelf registration statement relating to the offer and sale of notes that are not otherwise freely tradable; and

o use our reasonable best efforts to cause the shelf registration statement to be declared effective not later than the later to occur of the date that is 150 days after the date on which our obligation to file the shelf registration arises or 270 days after the date on which we issued the original notes; and

o use our reasonable best efforts to keep the shelf registration statement continuously effective until the earlier of two years from the date on which we issued the original notes (subject to extension under certain circumstances) and such shorter period ending when all the notes covered by the shelf registration statement have been sold pursuant to the shelf registration statement or are no longer restricted securities (as defined in Rule 144 under the Securities Act).

You will not be entitled, except if you were an initial purchaser of the original notes, to have your notes registered under the shelf registration statement, unless you agree in writing to be bound by the applicable provisions of the registration rights agreement. In order to sell your notes under the shelf registration statement, you generally must be named as a selling security holder in the related prospectus and must deliver a prospectus to purchasers. Consequently, you will be subject to the civil liability provisions under the Securities Act in connection with those sales and indemnification obligations under the registration rights agreements.

LIQUIDATED DAMAGES

A registration default will be deemed to have occurred if:

(1) the exchange offer registration statement is not declared effective within 270 days after the date on which we issued the original notes;

(2) the shelf registration statement is not declared effective by the later to occur of the date that is 150 days after the date on which our obligation to file the shelf registration arises or 270 days after the date on which we issued the original notes; or

(3) after either the exchange offer registration statement or the shelf registration statement is declared effective, such registration statement or the related prospectus thereafter ceases to be effective or usable (subject to certain exceptions) in connection with resales of original notes or exchange notes for the periods specified and in accordance with the registration rights agreement.

Additional interest will accrue on the notes subject to such registration default at a rate of 0.5% from and including the date on which any such registration default occurs to but excluding the date on which all such registration defaults have ceased to be continuing. In each case, such additional interest is payable in addition to any other interest payable from time to time with respect to the original notes and the exchange notes. The exchange notes will not contain any provisions regarding the payment of liquidated damages.

EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS

The exchange offer expires on the expiration date. The expiration date is 5:00 p.m., New York City time, on , 200 , unless we in our sole discretion extend the period during which the exchange offer is open, in which event the expiration date is the latest time and date on which the exchange offer, as so extended by us, expires. We reserve the right to extend the exchange offer at any time and from time to time prior to the expiration date by giving written notice to The Bank of New York, as the exchange agent, and by timely public announcement communicated in accordance with applicable law or regulation. During any extension of the exchange offer, all original notes previously tendered pursuant to the exchange offer and not validly withdrawn will remain subject to the exchange offer.

28

The exchange date will occur promptly after the expiration date. We expressly reserve the right to (i) terminate the exchange offer and not accept for exchange any original notes for any reason, including if any of the events set forth below under "--Conditions to the Exchange Offer" shall have occurred and shall not have been waived by us and (ii) amend the terms of the exchange offer in any manner, whether before or after any tender of the original notes. If any such termination or amendment occurs, we will notify the exchange agent in writing and will either issue a press release or give written notice to the holders of the original notes as promptly as practicable. Unless we terminate the exchange offer prior to 5:00 p.m., New York City time, on the expiration date, we will exchange the exchange notes for the original notes on the exchange date.

If we waive any material condition to the exchange offer, or amend the exchange offer in any other material respect, and if at the time that notice of such waiver or amendment is first published, sent or given to holders of original notes in the manner specified above, the exchange offer is scheduled to expire at any time earlier than the expiration of a period ending on the fifth business day from, and including, the date that such notice is first so published, sent or given, then the exchange offer will be extended until the expiration of such period of five business days.

This prospectus and the related letters of transmittal and other relevant materials will be mailed by us to record holders of original notes and will be furnished to brokers, banks and similar persons whose names, or the names of whose nominees, appear on the lists of holders for subsequent transmittal to beneficial owners of original notes.

HOW TO TENDER

The tender to us of original notes by you pursuant to one of the procedures set forth below will constitute an agreement between you and us in accordance with the terms and subject to the conditions set forth herein and in the applicable letter of transmittal.

General Procedures. A holder of an original note may tender the same by (i) properly completing and signing the applicable letter of transmittal or a facsimile thereof (all references in this prospectus to the letter of transmittal shall be deemed to include a facsimile thereof) and delivering the same, together with the certificate or certificates representing the original notes being tendered and any required signature guarantees (or a timely confirmation of a book-entry transfer, which we refer to as a Book-Entry Confirmation, pursuant to the procedure described below), to the exchange agent at its address set forth on the back cover of this prospectus on or prior to the expiration date or (ii) complying with the guaranteed delivery procedures described below.

If tendered original notes are registered in the name of the signer of the letter of transmittal and the exchange notes to be issued in exchange therefor are to be issued (and any untendered original notes are to be reissued) in the name of the registered holder, the signature of such signer need not be guaranteed. In any other case, the tendered original notes must be endorsed or accompanied by written instruments of transfer in form satisfactory to us and duly executed by the registered holder and the signature on the endorsement or instrument of transfer must be guaranteed by a firm, which we refer to as an Eligible Institution, that is a member of a recognized signature guarantee medallion program, which we refer to as an Eligible Program, within the meaning of Rule 17Ad-15 under the Exchange Act. If the exchange notes and/or original notes not exchanged are to be delivered to an address other than that of the registered holder appearing on the note register for the original notes, the signature on the letter of transmittal must be guaranteed by an Eligible Institution.

Any beneficial owner whose original notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender original notes should contact such holder promptly and instruct such holder to tender original notes on such beneficial owner's behalf. If such beneficial owner wishes to tender such original notes himself, such beneficial owner must, prior to completing and executing the letter of transmittal and delivering such original notes, either make appropriate arrangements to register ownership of the original notes in such beneficial owner's name or follow the procedures described in the immediately preceding paragraph. The transfer of record ownership may take considerable time.

Book-Entry Transfer. The exchange agent will make a request to establish an account with respect to the original notes at The Depository Trust Company, which we refer to as the Book-Entry Transfer Facility, for purposes of the exchange offer within two business days after receipt of this prospectus, and any financial institution that is a participant in the Book-Entry Transfer Facility's systems may make book-entry delivery of original notes by causing the Book-Entry Transfer Facility to transfer such original notes into the exchange agent's account at the Book-Entry Transfer Facility in accordance with the Book-Entry Transfer Facility's procedures for transfer. However, although delivery of original notes may be effected through book-entry transfer at the Book-Entry Transfer Facility, the letter of transmittal, with any required signature guarantees and any other required documents, must, in any case, be transmitted to and received by the exchange agent at the address specified on the back cover page of this prospectus on or prior to the expiration date or the guaranteed delivery procedures described below must be complied with.

THE METHOD OF DELIVERY OF ORIGINAL NOTES AND ALL OTHER DOCUMENTS IS AT YOUR ELECTION AND RISK. IF SENT BY MAIL, WE RECOMMEND THAT YOU USE REGISTERED MAIL, RETURN RECEIPT REQUESTED, OBTAIN PROPER INSURANCE, AND COMPLETE THE MAILING SUFFICIENTLY IN ADVANCE OF THE EXPIRATION DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR BEFORE THE EXPIRATION DATE.

Unless an exemption applies under the applicable law and regulations concerning "backup withholding" of federal income tax, the exchange agent will be required to withhold, and will withhold, 31% of the gross proceeds otherwise payable to a holder pursuant to the exchange offer if the holder does not provide its taxpayer identification number (social security number or employer identification number) and certify that such number is correct. Each tendering holder should complete and sign the main signature form and the Substitute Form W-9 included as part of the letter of transmittal, so as to provide the information and certification necessary to avoid backup withholding, unless an applicable exemption exists and is proved in a manner satisfactory to us and the exchange agent.

Guaranteed Delivery Procedures. If a holder desires to accept the exchange offer and time will not permit a letter of transmittal or original notes to reach the exchange agent before the expiration date, a tender may be effected if the exchange agent has received at its office listed on the back cover hereof on or prior to the expiration date a letter, telegram or facsimile transmission from an Eligible Institution setting forth the name and address of the tendering holder, the names in which the original notes are registered, the principal amount of the original notes and, if possible, the certificate numbers of the original notes to be tendered, and stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange trading days after the date of execution of such letter, telegram or facsimile transmission by the Eligible Institution, the original notes, in proper form for transfer, will be delivered by such Eligible Institution together with a properly completed and duly executed letter of transmittal (and any other required documents). Unless original notes being tendered by the above-described method (or a timely Book-Entry Confirmation) are deposited with the exchange agent within the time period set forth above (accompanied or preceded by a properly completed letter of transmittal and any other required documents), we may, at our option, reject the tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible Institutions for the purposes described in this paragraph are being delivered with this prospectus and the related letter of transmittal.

A tender will be deemed to have been received as of the date when the tendering holder's properly completed and duly signed letter of transmittal accompanied by the original notes (or a timely Book-Entry Confirmation) is received by the exchange agent. Issuances of exchange notes in exchange for original notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram or facsimile transmission to similar effect (as provided above) by an Eligible Institution will be made only against deposit of the letter of transmittal (and any other required documents) and the tendered original notes (or a timely Book-Entry Confirmation).

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of original notes will be determined by us and our determination will be final and binding. We reserve the absolute right to reject any or all tenders not in proper form or the acceptances for exchange of which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right

30

to waive any of the conditions of the exchange offer or any defect or irregularities in tenders of any particular holder whether or not similar defects or irregularities are waived in the case of other holders. None of us, the exchange agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or shall incur any liability for failure to give any such notification. Our interpretation of the terms and conditions of the exchange offer (including the letters of transmittal and the instructions thereto) will be final and binding.

TERMS AND CONDITIONS OF THE LETTERS OF TRANSMITTAL

The letters of transmittal contain, among other things, the following terms and conditions, which are part of the exchange offer.

The party tendering original notes for exchange, to whom we refer to as the Transferor, exchanges, assigns and transfers the original notes to us and irrevocably constitutes and appoints the exchange agent as the Transferor's agent and attorney-in-fact to cause the original notes to be assigned, transferred and exchanged. The Transferor represents and warrants that it has full power and authority to tender, exchange, assign and transfer the original notes and to acquire exchange notes issuable upon the exchange of such tendered original notes, and that, when the same are accepted for exchange, we will acquire good and unencumbered title to the tendered original notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The Transferor also warrants that it will, upon request, execute and deliver any additional documents deemed by us to be necessary or desirable to complete the exchange, assignment and transfer of tendered original notes. The Transferor further agrees that acceptance of any tendered original notes by us and the issuance of exchange notes in exchange therefor shall constitute performance in full by us of our obligations under the registration rights agreement and that we shall have no further obligations or liabilities thereunder (except in certain limited circumstances). All authority conferred by the Transferor will survive the death or incapacity of the Transferor and every obligation of the Transferor shall be binding upon the heirs, legal representatives, successors, assigns, executors and administrators of such Transferor.

See "--Terms of the Exchange."

WITHDRAWAL RIGHTS

Original notes tendered pursuant to the exchange offer may be withdrawn at any time prior to the expiration date. For a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the exchange agent at its address set forth on the back cover of this prospectus. Any such notice of withdrawal must specify the person named in the letter of transmittal as having tendered original notes to be withdrawn, the certificate numbers of original notes to be withdrawn, the principal amount of original notes to be withdrawn (which must be an authorized denomination), a statement that such holder is withdrawing his election to have such original notes exchanged, and the name of the registered holder of such original notes, and must be signed by the holder in the same manner as the original signature on the letter of transmittal (including any required signature guarantees) or be accompanied by evidence satisfactory to us that the person withdrawing the tender has succeeded to the beneficial ownership of the original notes being withdrawn. The exchange agent will return the properly withdrawn original notes promptly following receipt of notice of withdrawal. All questions as to the validity of notices of withdrawals, including time of receipt, will be determined by us, and our determination will be final and binding on all parties.

ACCEPTANCE OF ORIGINAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

Upon the terms and subject to the conditions of the exchange offer, the acceptance for exchange of original notes validly tendered and not withdrawn and the issuance of the exchange notes will be made on the exchange date. For the purposes of the exchange offer, we shall be deemed to have accepted for exchange validly tendered original notes when, as and if we have given written notice thereof to the exchange agent.

The exchange agent will act as agent for the tendering holders of original notes for the purposes of receiving exchange notes from us and causing the original notes to be assigned, transferred and

31

exchanged. Upon the terms and subject to the conditions of the exchange offer, delivery of exchange notes to be issued in exchange for accepted original notes will be made by the exchange agent promptly after acceptance of the tendered original notes. Original notes not accepted for exchange by us will be returned without expense to the tendering holders (or in the case of original notes tendered by book-entry transfer into the exchange agent's account at the Book-Entry Transfer Facility pursuant to the procedures described above, such non-exchanged original notes will be credited to an account maintained with such Book-Entry Transfer Facility) promptly following the expiration date or, if we terminate the exchange offer prior to the expiration date, promptly after the exchange offer is so terminated.

CONDITIONS TO THE EXCHANGE OFFER

We are not required to accept for exchange, or to issue exchange notes in exchange for, any outstanding original notes. We may terminate or extend the exchange offer by oral or written notice to the exchange agent and by timely public announcement communicated in accordance with applicable law or regulation, if:

o any federal law, statute, rule, regulation or interpretation of the staff of the SEC has been proposed, adopted or enacted that, in our judgment, might impair our ability to proceed with the exchange offer or otherwise make it inadvisable to proceed with the exchange offer;

o an action or proceeding has been instituted or threatened in any court or by any governmental agency that, in our judgement might impair our ability to proceed with the exchange offer or otherwise make it inadvisable to proceed with the exchange offer;

o there has occurred a material adverse development in any existing action or proceeding that might impair our ability to proceed with the exchange offer or otherwise make it inadvisable to proceed with the exchange offer;

o any stop order is threatened or in effect with respect to the registration statement of which this prospectus is a part or the qualification of the indenture under the Trust Indenture Act of 1939;

o all governmental approvals that we deem necessary for the consummation of the exchange offer have not been obtained;

o there is a change in the current interpretation by the staff of the SEC which permits holders who have made the required representations to us to resell, offer for resale, or otherwise transfer exchange notes issued in the exchange offer without registration of the exchange notes and delivery of a prospectus; or

o a material adverse change shall have occurred in our business, condition, operations or prospects.

The foregoing conditions are for our sole benefit and may be asserted by us with respect to all or any portion of the exchange offer regardless of the circumstances (including any action or inaction by us) giving rise to such condition or may be waived by us in whole or in part at any time or from time to time in our sole discretion. The failure by us at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right, and each right will be deemed an ongoing right which may be asserted at any time or from time to time. In addition, we have reserved the right, notwithstanding the satisfaction of each of the foregoing conditions, to terminate or amend the exchange offer.

Any determination by us concerning the fulfillment or non-fulfillment of any conditions will be final and binding upon all parties.

EXCHANGE AGENT

The Bank of New York has been appointed as the exchange agent for the exchange offer. Letters of transmittal must be addressed to the exchange agent at its address set forth on the back cover page of this prospectus. Delivery to an address other than as set forth herein, or transmissions of instructions via a facsimile or telex number other than the ones set forth herein, will not constitute a valid delivery.

32

SOLICITATION OF TENDERS; EXPENSES

We have not retained any dealer-manager or similar agent in connection with the exchange offer and will not make any payments to brokers, dealers or others for soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will reimburse it for reasonable out-of-pocket expenses in connection therewith. We will also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding tenders for their customers. The expenses to be incurred in connection with the exchange offer, including the fees and expenses of the exchange agent and printing, accounting and legal fees, will be paid by us and are estimated at approximately $250,000.

No dealer, salesperson or other individual has been authorized to give any information or to make any representations not contained in this prospectus in connection with the exchange offer. If given or made, such information or representations must not be relied upon as having been authorized by us. Neither the delivery of this prospectus nor any exchange made hereunder shall, under any circumstances, create any implication that there has been no change in our affairs since the respective dates as of which information is given herein.

The exchange offer is not being made to (nor will tenders be accepted from or on behalf of) holders of original notes in any jurisdiction in which the making of the exchange offer or the acceptance thereof would not be in compliance with the laws of such jurisdiction. However, we may, at our discretion, take such action as we may deem necessary to make the exchange offer in any such jurisdiction and extend the exchange offer to holders of original notes in such jurisdiction. In any jurisdiction the securities laws or blue sky laws of which require the exchange offer to be made by a licensed broker or dealer, the exchange offer is being made on behalf of us by one or more registered brokers or dealers which are licensed under the laws of such jurisdiction.

APPRAISAL RIGHTS

You will not have dissenters' rights or appraisal rights in connection with the exchange offer.

FEDERAL INCOME TAX CONSEQUENCES

The exchange of original notes for exchange notes by holders should not be a taxable exchange for federal income tax purposes, and holders should not recognize any taxable gain or loss or any interest income as a result of such exchange. See "Certain United States Federal Income Tax Considerations."

OTHER

Participation in the exchange offer is voluntary and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decisions on what action to take.

As a result of the making of, and upon acceptance for exchange of all validly tendered original notes pursuant to the terms of this exchange offer, we will have fulfilled a covenant contained in the terms of the original notes and the registration rights agreement. Holders of the original notes who do not tender their original notes in the exchange offer will continue to hold such original notes and will be entitled to all the rights, and limitations applicable thereto, under the indenture, except for any such rights under the registration rights agreement which by their terms terminate or cease to have further effect as a result of the making of this exchange offer. See "Description of Notes." All untendered original notes will continue to be subject to the restriction on transfer set forth in the indenture. To the extent that original notes are tendered and accepted in the exchange offer, the trading market, if any, for the original notes could be adversely affected. See "Risk Factors -- Your ability to sell your original notes may be significantly more limited and the price at which you may be able to sell your original notes may be significantly lower if you do not exchange them for registered exchange notes in the exchange offer."

We may in the future seek to acquire untendered original notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plan to acquire any original notes which are not tendered in the exchange offer.

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

The following is management's discussion and analysis of certain significant factors which have affected the financial condition and results of operations of MidAmerican Energy Holdings Company, or the Company, during the periods included in the accompanying statements of operations. This discussion should be read in conjunction with "Selected Consolidated Financial and Operating Data" and the Company's historical financial statements and the notes to those statements included elsewhere in this prospectus.

As a result of the recent acquisitions of Northern Natural Gas and Kern River, the acquisition of the electricity distribution business of Yorkshire Electricity and the simultaneous sale of the electricity and gas supply business of Northern Electric to the former owner of Yorkshire Electricity, which together are referred to as the Northern Electric/Yorkshire Electricity swap, and the acquisition by a private investor group on March 14, 2000, the Company's future results will differ from the Company's historical results.

GENERAL

The Company is a United States-based privately owned global energy company with publicly held fixed income securities that generates, distributes and supplies energy to utilities, government entities, retail customers and other customers located throughout the world. Through the Company's subsidiaries, the Company's operations are organized and managed on seven distinct platforms:
MidAmerican Energy, Northern Natural Gas, Kern River, CE Electric UK (which includes Northern Electric and Yorkshire Electricity), CalEnergy Generation-Domestic, CalEnergy Generation-Foreign and HomeServices. These platforms, with the exception of Northern Natural Gas and Kern River, are discussed in detail in the notes to the Company's financial statements included in this prospectus.

NORTHERN NATURAL GAS COMPANY

On August 16, 2002, the Company acquired all of the outstanding capital stock of Northern Natural Gas from Dynegy, Inc. and its affiliates for $899 million, net of cash acquired of $1.4 million, subject to adjustment for working capital. The Company used the proceeds from a $950 million investment in its subsidiary trust's preferred securities by Berkshire Hathaway to finance this acquisition.

Northern Natural Gas owns a 16,600-mile interstate natural gas pipeline extending from southwest Texas to the upper Midwest region of the United States with a design capacity of 4.4 Bcf of natural gas per day. Northern Natural Gas also operates three natural gas storage facilities and two liquefied natural gas peaking units with a total storage capacity of 59 Bcf and peak delivery capability of over 1.3 Bcf of natural gas per day. Northern Natural Gas accesses natural gas supply from many of the larger producing regions in North America, including the Rocky Mountains, Hugoton, Permian, Anadarko and Western Canadian basins. The pipeline system provides transportation and storage services to utilities, municipalities, other pipeline companies, gas marketers and industrial and commercial users.

KERN RIVER GAS TRANSMISSION COMPANY

On March 27, 2002, the Company acquired Kern River from a subsidiary of The Williams Companies, Inc., or Williams. Kern River owns and operates a 926-mile interstate natural gas pipeline extending from Wyoming to markets in California, Nevada and Utah and accessing natural gas supply from large producing regions in the Rocky Mountains and Canada. The Company paid $420 million, net of cash acquired of $7.7 million, including transaction costs and working capital adjustments, for Kern River. At the time of the acquisition, Kern River had $505 million of indebtedness, the unamortized portion of which remains outstanding. The design capacity of the existing Kern River pipeline is 100% contracted through 2011 and 84% contracted through 2016.

In connection with the Kern River acquisition, the Company issued $323 million of 11% mandatorily redeemable preferred securities of a subsidiary trust due March 12, 2012 with scheduled principal payments beginning in 2005, and $127 million of no par, zero coupon convertible preferred stock to

38

Berkshire Hathaway. Each share of such preferred stock is convertible at the option of the holder into one share of Company common stock subject to certain adjustments as described in the Company's amended and restated articles of incorporation.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements and related documents in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 2 to the consolidated financial statements for the year ended December 31, 2001 included in this prospectus describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. Estimates are used for, but not limited to, the accounting for revenue, the effects of certain types of regulation, impairment of long-lived assets, and contingent liabilities. Actual results could differ from these estimates. The following critical accounting policies are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements.

REVENUE RECOGNITION

Revenues are recorded based upon services rendered and electricity, gas and steam delivered, distributed or supplied to the end of the period. Where there is an over recovery of United Kingdom distribution business revenues against the maximum regulated amount, revenues are deferred in an amount equivalent to the over recovered amount. The deferred amount is deducted from revenue and included in other liabilities. Where there is an under recovery, no anticipation of any potential future recovery is made.

MidAmerican Energy records unbilled revenues representing the estimated amounts customers will be billed for services rendered between the meter reading dates in a particular month and the end of that month. The unbilled revenues estimate is reversed in the following month. To the extent the estimated amount differs from that amount subsequently billed, the timing of revenues will be affected. Accrued unbilled revenues are included in accounts receivable on the consolidated balance sheets.

Revenues from the transportation and storage of gas are recognized based on contractual terms and the related volumes. Northern Natural Gas and Kern River are subject to the FERC's regulations and, accordingly, certain revenues collected may be subject to possible refunds upon final orders in pending rate cases. Northern Natural Gas and Kern River record rate refund liabilities considering their regulatory proceedings and other third party regulatory proceedings, advice of counsel and estimated total exposure, as discounted and risk weighted, as well as collection and other risks.

SFAS NO. 71--ACCOUNTING FOR THE EFFECTS OF CERTAIN TYPES OF REGULATION

MidAmerican Energy, Kern River and Northern Natural Gas prepare their financial statements in accordance with the provisions of Statement of Financial Accounting Standards No. 71, which differs in certain respects from the application of generally accepted accounting principles by non-regulated businesses. In general, SFAS No. 71 recognizes that accounting for rate-regulated enterprises should reflect the economic effects of regulation. As a result, a regulated utility is required to defer the recognition of costs (a regulatory asset) or the recognition of obligations (a regulatory liability) if it is probable that, through the rate-making process, there will be a corresponding increase or decrease in future rates. Accordingly, MidAmerican Energy, Kern River and Northern Natural Gas have deferred certain costs, which will be amortized over various future periods. To the extent that collection of such costs or payment of obligations is no longer probable as a result of changes in regulation, the associated regulatory asset or liability is charged or credited to income.

A possible consequence of deregulation of the regulated energy industry is that SFAS No. 71 may no longer apply. If portions of the Company's subsidiaries' regulated energy operations no longer meet the criteria of SFAS No. 71, the Company could be required to write off the related regulatory assets and liabilities from its balance sheet, and thus a material adjustment to earnings in that period could result if regulatory assets are not recovered in transition provisions of any deregulation legislation.

39

The Company continues to evaluate the applicability of SFAS No. 71 to its regulated energy operations and the recoverability of these assets and liabilities through rates as there are on-going changes in the regulatory and economic environment.

IMPAIRMENT OF LONG-LIVED ASSETS

The Company's long-lived assets consist primarily of property, plant and equipment, goodwill and intangible assets that were acquired in business acquisitions. The Company believes the useful lives assigned to the depreciable assets, which generally range from 1 to 87 years, are reasonable.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Triggering events include a significant change in the extent or manner in which long-lived assets are being used or in their physical condition, in legal factors, or in the business climate that could affect the value of the long-lived assets, including changes in regulation. The interpretation of such events requires judgment from management as to whether such an event has occurred and is required. If an event occurs that could affect the carrying value of the asset and management does not identify it as triggering event, future results of operations could be significantly affected.

Upon the occurrence of a triggering event, the carrying amount of a long-lived asset is reviewed to assess whether the recoverable amount has declined below its carrying amount. The recoverable amount is the estimated net future cash flows that the Company expects to recover from the future use of the asset, undiscounted and without interest, plus the asset's residual value on disposal. Where the recoverable amount of the long-lived asset is less than the carrying value, an impairment loss would be recognized to write down the asset to its fair value which is based on discounted estimated cash flows from the future use of the asset.

The estimate of cash flows arising from future use of the asset that are used in the impairment analysis requires judgment regarding what the Company would expect to recover from future use of the asset. Any changes in the estimates of cash flows arising from future use of the asset or the residual value of the asset on disposal based on changes in the market conditions, changes in the use of the asset, management's plans, the determination of the useful life of the asset and technology changes in the industry could significantly change the calculation of the fair value or recoverable amount of the asset and the resulting impairment loss, which could significantly affect the results of operations.

Effective January 1, 2002, the Company adopted Statement of Financial Accounting Standard No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142 requires that amortization of goodwill and indefinite-lived intangible assets be discontinued and that these assets be tested for impairment annually. During the second quarter of 2002, the Company completed its initial impairment testing of goodwill primarily using a discounted cash flow methodology. No impairment was indicated as a result of the initial testing.

CONTINGENT LIABILITIES

The Company establishes reserves for estimated loss contingencies when it is management's assessment that a loss is probable and the amount of the loss can be reasonably estimated. Revisions to contingent liabilities are reflected in income in the period in which different facts or information become known or circumstances change that affect the previous assumptions with respect to the likelihood or amount of loss. Reserves for contingent liabilities are based upon management's assumptions and estimates, and advice of legal counsel or other third parties regarding the probable outcomes of any matters. Should the outcomes differ from the assumptions and estimates, revisions to the estimated reserves for contingent liabilities would be required.

RESULTS OF OPERATIONS FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2002 AND 2001

Operating revenue for the three months ended September 30, 2002, was $1,238.5 million compared with $1,076.8 million for the same period in 2001, an increase of 15.0%. MidAmerican Energy operating

40

revenue increased for the three months ended September 30, 2002, to $538.7 million from $507.7 million for the same period in 2001, primarily due to higher volumes for regulated electricity. CE Electric UK Funding operating revenue decreased for the three months ended September 30, 2002, to $193.4 million from $316.3 million for the same period in 2001, primarily due to the sale of Northern Supply in September 2001 of $209 million, partially offset by Yorkshire Electricity distribution revenue of $103 million. The remaining change in operating revenue primarily relates to (1) the increase of revenue at HomeServices of $147.6 million primarily due to acquisitions in 2002 and late 2001, (2) the acquisition of Kern River in March 2002, which accounted for $39.9 million of operating revenue and (3) the acquisition of Northern Natural Gas in August 2002, which accounted for $39.1 million of operating revenue.

Operating revenue for the nine months ended September 30, 2002, was $3,404.5 million compared with $3,756.9 million for the same period in 2001, a decrease of 9.4%. MidAmerican Energy operating revenue decreased for the nine months ended September 30, 2002, to $1,582.6 million from $1,897.8 million for the same period in 2001, primarily due to lower volumes and rates for regulated and non-regulated gas. CE Electric UK Funding operating revenues decreased for the nine months ended September 30, 2002, to $597.0 million from $1,222.3 million for the same period in 2001, primarily due to the sale of Northern Supply in September 2001 of $889 million, partially offset by Yorkshire Electricity distribution revenue of $276 million. The remaining change in operating revenue primarily relates to (1) the increase of revenue at HomeServices of $382.5 million primarily due to acquisitions in 2002 and late 2001, (2) the acquisition of Kern River in March 2002, which accounted for $87.0 million of operating revenue and (3) the acquisition of Northern Natural Gas in August 2002, which accounted for $39.1 million of operating revenue.

The following data represents sales from MidAmerican Energy:

MidAmerican Energy's electric retail sales and electric sales for resale increased for three months ended September 30, 2002, from the same period in 2001 due to higher temperatures in the third quarter of 2002. Retail gas supplied decreased due to decreased non-regulated activity for the three months ended September 30, 2002, compared to the same period in 2001.

MidAmerican Energy electric retail sales increased for the nine months ended September 30, 2002 from the same period in 2001 due primarily to higher temperatures in 2002, primarily in the third quarter of 2002. Electric sales for resale increased for the nine months ended September 30, 2002 from the same period in 2001 due to availability of Cordova Energy Company LLC, or Cordova Energy, an indirect wholly owned subsidiary of the Company, and lower retail usage in the first quarter of 2002, allowing for more energy to be sold in the wholesale markets. Regulated and non-regulated gas supplied decreased due to colder temperatures during the first quarter of 2001 and decreased non-regulated activity.

CE Electric UK Funding distributed 9,473 GWh of electricity in the three months ended September 30, 2002, compared with 4,457 GWh of electricity in the same period in 2001. CE Electric UK Funding distributed 30,252 GWh of electricity in the nine months ended September 30, 2002, compared with 13,016 GWh of electricity in the same period in 2001. The increase in electricity distributed for both periods ended September 30, 2002, is primarily due to the acquisition of Yorkshire Electricity distribution.

Kern River transported 90,532,000 MMBtus in the three months ended September 30, 2002, and 190,195,000 MMBtus since the Company acquired Kern River on March 27, 2002.

41

Northern Natural Gas transported 121,028,500 MMBtus since the Company acquired Northern Natural Gas on August 16, 2002.

Income on equity investments for the three months ended September 30, 2002, was $10.9 million compared with $6.3 million for the same period in 2001. The increase was primarily due to higher earnings at CE Gen as a result of higher energy prices in 2002 and the allowance for doubtful accounts accrual in 2001, and income from a HomeServices' joint venture which was fully consolidated in 2001, partially offset by lower equity earnings due to impairment of alternative energy project funds in 2002.

Income on equity investments for the nine months ended September 30, 2002, was $29.9 million compared with $23.6 million for the same period in 2001. The increase was primarily due to income from a HomeServices' joint venture that was fully consolidated in 2001.

Interest and other income for the three months ended September 30, 2002, was $32.7 million compared with $223.9 million for the same period in 2001. The decrease was primarily due to the $200.3 million gain on the sale of Northern Supply in September 2001.

Interest and other income for the nine months ended September 30, 2002, was $115.3 million compared with $262.5 million for the same period in 2001. The decrease was primarily due to the gain on sale of Northern Supply in September 2001, partially offset by the $54.3 million gain on the sale of various CE Gas Holdings assets in May 2002.

Cost of sales for the three months ended September 30, 2002, was $443.1 million compared with $473.0 million for the same period in 2001, a decrease of 6.3%. Cost of sales for the nine months ended September 30, 2002, was $1,283.2 million compared with $2,010.2 million for the same period in 2001, a decrease of 36.2%. The decreases for both periods relates primarily to the sale of Northern Supply and decreased gas revenue at MidAmerican Energy, partially offset by increase cost of sales at HomeServices due to higher commission on the higher revenues as a result of acquisitions.

Operating expenses for the three months ended September 30, 2002, were $343.3 million compared with $293.9 million for the same period in 2001. The increase was primarily due to higher costs at HomeServices of $32.3 million as a result of acquisitions and operating expenses due to the acquisition of Northern Natural Gas of $26.6 million, partially offset by lower costs at MidAmerican Energy of $23.4 million due to the restructuring of the Cooper Nuclear Station contract with the Nebraska Public Power District, or NPPD, and lower energy efficiency expenses.

Operating expenses for the nine months ended September 30, 2002, were $948.9 million compared with $844.8 million for the same period in 2001. The increase was primarily due to higher costs at HomeServices of $77.5 million as a result of acquisitions and operating expenses due to the acquisitions of Northern Natural Gas of $26.6 million and Kern River of $18.2 million, partially offset by lower costs at MidAmerican Energy of $22.0 million due to the restructuring of the Cooper Nuclear Station contract and lower energy efficiency expenses.

Depreciation and amortization for the three months ended September 30, 2002, was $129.4 million compared with $122.7 million for the same period in 2001. The increase was primarily due to higher depreciation at MidAmerican Energy of $12.5 million primarily due to higher Iowa revenue sharing accruals, the commencement of commercial operation at CE Casecnan of $5.8 million, and depreciation expense due to the acquisitions of Northern Natural Gas of $5.8 million and Kern River of $4.9 million, partially offset by the discontinuance of amortizing goodwill beginning January 1, 2002 of $24.8 million.

Depreciation and amortization for the nine months ended September 30, 2002, was $386.5 million compared with $395.3 million for the same period in 2001. The decrease was primarily due to discontinuance of amortizing goodwill beginning January 1, 2002 of $74.7 million, partially offset by the commencement of commercial operations at CE Casecnan of $17.6 million, higher depreciation at MidAmerican Energy of $17.3 million primarily due to higher Iowa revenue sharing accruals, depreciation expense due to the acquisitions of Kern River of $12.2 million and Northern Natural Gas of $5.8 million and increased amortization at HomeServices of $8.9 million due to intangible assets amortization related to acquisitions.

42

Interest expense, less amounts capitalized, for the three months ended September 30, 2002, was $159.3 million compared with $99.9 million for the same period in 2001, an increase of 59.5%. The increase was due primarily to the increase of interest expense at CE Electric UK Funding of $24.4 million predominantly due to the debt related to the Yorkshire Electricity acquisition, the discontinuance of capitalizing interest related to the Casecnan Project of $13.0 million, and interest expense due to the acquisitions of Kern River and Northern Natural Gas of $12.9 million and $8.1 million, respectively.

Interest expense, less amounts capitalized, for the nine months ended September 30, 2002, was $438.9 million compared with $290.2 million for the same period in 2001, an increase of 51.2%. The increase was primarily due to the increase of interest expense at CE Electric UK Funding of $68.4 million predominantly due to the debt related to the Yorkshire Electricity acquisition, the discontinuance of capitalizing interest related to the Casecnan Project and the Cordova Project of $37.7 million and $9.7 million, respectively, and interest expense due to debt related to the acquisitions of Kern River and Northern Natural Gas of $22.4 million and $8.1 million, respectively.

Tax expense for the three months ended September 30, 2002, was $26.8 million compared with $241.9 million for the same period in 2001. The decrease is due primarily to the tax expense of $199.9 million related to the sale of the Northern Supply business in September 2001 and the recognition of a tax benefit of $21.1 million in connection with the sale of the CE Gas Holdings assets in May 2002.

Tax expense for the nine months ended September 30, 2002, was $80.2 million compared to $296.1 million for the same period in 2001. The decrease is due primarily to the tax expense related to the sale of the Northern Supply business in September 2001, the release of the tax obligation of $35.7 million in connection with the execution of the TPL restructuring agreement in the U.K., and the recognition of a tax benefit in connection with the sale of the CE Gas Holdings assets in 2002.

Minority interest for the three months ended September 30, 2002, was $45.3 million compared with $27.8 million for the same period in 2001. Minority interest for the nine months ended September 30, 2002, was $105.2 million compared with $80.0 million for the same periods in 2001. Minority interest includes the dividends on the Company-obligated mandatorily redeemable preferred securities of subsidiary trusts. The increases in minority interest for both periods is primarily due to the issuance of Company-obligated mandatorily redeemable preferred securities of subsidiary trusts relating to the Kern River and Northern Natural Gas acquisitions.

Effective January 1, 2001, the Company changed its accounting policy regarding major maintenance and repairs for nonregulated gas projects, nonregulated plant overhaul costs and geothermal well rework costs to the direct expense method from the former policy of monthly accruals based on long-term scheduled maintenance plans for the gas projects and deferral and amortization of plant overhaul costs and geothermal well rework costs over the estimated useful lives. The cumulative effect of the change in accounting principle for 2001 was $4.6 million, net of taxes of $0.7 million.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2001 AND THE PERIODS MARCH 14, 2000 THROUGH DECEMBER 31, 2000, AND JANUARY 1, 2000 THROUGH MARCH 13, 2000

The following is a discussion of the historical results of the Company for the year ended December 31, 2001 and the period March 14, 2000 through December 31, 2000, and of the Company's predecessor, MEHC (Predecessor), for the period January 1, 2000 through March 13, 2000. Results for the Company include the impact of the Company's acquisition by a private investor group beginning March 14, 2000 which are predominately the minority interest costs on issuance of Company-obligated mandatorily redeemable preferred securities of a subsidiary trust and the effects of purchase accounting, including goodwill amortization and fair value adjustments to the carrying value of assets and liabilities. In order to provide comparability between periods, the Company has prepared pro forma results as if the Company's acquisition by a private investor group had occurred at the beginning of each year after giving effect to pro forma adjustments related to the acquisition, including the issuance of the 11% trust preferred securities. The discussion therefore will highlight any significant variances on a pro forma basis from the year ended December 31, 2000 to the year ended December 31, 2001.

43

Pro forma operating revenue for the year ended December 31, 2001 was $5,060.6 million compared with $5,235.0 million for the same period in 2000, a decrease of 3.3%. MidAmerican Energy operating revenue increased for the year ended December 31, 2001 to $2,752.5 million from $2,576.9 million for the same period in 2000, primarily due to increases in volumes of non-regulated gas sold and increases in volumes and prices on off-system electricity sales. CE Electric UK operating revenue decreased for the year ended December 31, 2001 to $1,444.0 million from $1,997.9 million for the same period in 2000, primarily due to the Northern Electric/Yorkshire Electricity swap and changes in foreign exchange rates. The supply business that was sold is generally a high volume business that tends to operate at lower profitability levels than the distribution business. The remaining increase primarily relates to the increase of revenue at HomeServices due to acquisitions and the inclusion of a joint venture which was previously accounted for as an equity investment and the commencement of operations of the Cordova project in June 2001.

Regulated and Non-Regulated Gas Supplied
 (Thousands of MMBtus) ....................    264,338     174,385

MidAmerican Energy electric retail sales increased for the year ended December 31, 2001 from the same period in 2000 due to the more extreme temperatures substantially offset by a decrease in non-weather related sales. Electric wholesale sales increased for the year ended December 31, 2001 from the same period in 2000 due to higher production at the Cooper and Neal power plants and favorable market conditions. Regulated and non-regulated gas supplied increased due principally to growth in the non-regulated markets for the year ended December 31, 2001 compared to the same period in 2000.

The following data represents the supply and distribution operations in the United Kingdom:

Gas Supplied (Thousands of MMBtus) .........   40,738     51,035
Electricity Distributed (GWh) ..............   23,770     16,350

The decrease in electricity and gas supplied for the year ended December 31, 2001 is due to the sale of Northern Electric's electricity and gas supply business in September 2001. The increase in electricity distributed for the year ended December 31, 2001 was due to the addition of Yorkshire Electricity and changes in demand in the distribution area.

Pro forma interest and other income for the year ended December 31, 2001 was $96.7 million compared with $114.4 million for the same period in 2000. The decrease was due primarily to reduced interest income and lower income from equity investments.

The non-recurring gains in 2001 are comprised mainly of the pre-tax gain on the sale of Northern Electric's electricity and gas supply business of $196.7 million, the loss on the impairment of TPL of $58.8 million, the gain on the sale of Telephone Flat, a geothermal development project, of $20.7 million, the gain on the transfer of shares of Bali, an indirect wholly owned subsidiary of the Company, of $10.4 million, and the gain on the sale of Western States Geothermal Company, an indirect wholly owned subsidiary of the Company, of $9.8 million. The after-tax gains and (losses) for the sale of Northern Electric's electricity and gas supply business, the TPL impairment, the Telephone Flat sale, the transfer of the Bali shares, and the Western States Geothermal sale were $10.8 million, ($20.7) million, $12.2 million, $6.5 million and $6.4 million, respectively.

44

Pro forma cost of sales for the year ended December 31, 2001 was $2,705.0 million compared with $3,029.7 million for the same period in 2000, a decrease of 10.7%. The decrease relates primarily to decreased cost of sales at CE Electric UK due to the sale of Northern Electric's electricity and gas supply business, lower foreign exchange rates and lower electricity volumes and prices, partially offset by increased volumes and prices for both regulated and non-regulated gas at MidAmerican Energy, and acquisitions at HomeServices.

Pro forma operating expenses for the year ended December 31, 2001 were $1,176.4 million compared with $1,123.6 million for the same period in 2000. The increase was primarily due to higher costs at HomeServices due to acquisitions and the inclusion of a joint venture which was previously accounted for as an equity investment and higher costs at MidAmerican Energy due to costs related to Cooper Nuclear Station, accounts receivable discounts and bad debts, partially offset by lower costs at CE Electric UK due to the sale of Northern Electric's electricity and gas supply business, lower pension costs and a lower exchange rate, partially offset by the addition of Yorkshire Electricity.

Pro forma depreciation and amortization for the year ended December 31, 2001 was $538.7 million compared with $479.6 million for the same period in 2000. This increase was due to higher depreciation at MidAmerican Energy due to inclusion of an Iowa revenue sharing accrual and an increase in depreciation rates implemented in 2001 and amortization of intangible assets related to the HomeServices acquisitions, partially offset by lower depreciation at CE Electric UK due to lower amortization of operational assets and a lower exchange rate, partially offset by the addition of Yorkshire Electricity.

Pro forma interest expense, less amounts capitalized, for the year ended December 31, 2001 was $412.8 million compared with $398.1 million for the same period in 2000, an increase of 3.7%. This increase is due to increased interest expense associated with the debt acquired with Yorkshire Electricity and lower capitalized interest on the mineral extraction process, partially offset by lower average outstanding debt balances and lower foreign exchange rates at Northern Electric.

The loss on non-recurring items of $7.6 million in the period from January 1, 2000 through March 13, 2000 represents the costs incurred related to the Company's acquisition by a private investor group.

Pro forma tax expense for the year ended December 31, 2001 was $250.1 million compared with $81.6 million for the same period in 2000. The increase is due primarily to the tax on the gain related to the sale of Northern Electric's electricity and gas supply business and higher pre-tax income.

Pro forma minority interest for the year ended December 31, 2001 was $106.5 million compared with $104.3 million for the same period in 2000. The increase is primarily due to increased minority interest at HomeServices.

The cumulative effect of change in accounting principle of $4.6 million in 2001 represents the change in accounting for major maintenance and overhauls.

Pro forma net income for the year ended December 31, 2001 was $142.7 million compared with $124.9 million for the same period in 2000.

RESULTS OF OPERATIONS FOR THE PERIODS MARCH 14, 2000 THROUGH DECEMBER 31, 2000, JANUARY 1, 2000 THROUGH MARCH 13, 2000 AND FOR THE YEAR ENDED DECEMBER 31, 1999

The following is a discussion of the historical results of the Company for the period March 14, 2000 through December 31, 2000, and of MEHC (Predecessor) for the period January 1, 2000 through March 13, 2000, and for the year ended December 31, 1999. Results for the Company include the results of MEHC (Predecessor) beginning March 14, 2000, in conjunction with the Company's acquisition by a private investor group. The impact of the transaction is reflected in the Company's results of operations, predominately minority interest costs on issuance of Company-obligated mandatorily redeemable preferred securities of a subsidiary trust and the effects of purchase accounting, including goodwill amortization and fair value adjustments to the carrying value of assets and liabilities. In order to provide comparability between periods, the Company has prepared pro forma results as if the Company's acquisition by a private investor group and the MidAmerican Energy acquisition had occurred at the

45

beginning of each year after giving effect to pro forma adjustments related to the acquisitions, including the sales of the qualified facilities, the redemption of limited recourse notes, the redemption of the senior discount notes and the issuance of the 11% trust preferred securities. The discussion therefore will highlight any significant variances on a pro forma basis from the year ended December 31, 1999 to the year ended December 31, 2000.

Pro forma operating revenue for the year ended December 31, 2000 was $5,235.0 million compared with $4,572.8 million for the same period in 1999, an increase of 14.5%. MidAmerican Energy operating revenue increased for the year ended December 31, 2000 to $2,576.9 million from $1,871.9 million for the same period in 1999, primarily due to increases in non-regulated gas sales and higher prices in regulated gas. CE Electric UK operating revenue decreased for the year ended December 31, 2000 to $1,997.9 million from $2,072.2 million for the same period in 1999, primarily due to lower volumes of electricity supplied in the franchise area and lower foreign exchange rates partially offset by higher volumes of electricity supplied out of the franchise area and distribution revenue from access charges. The remaining increase primarily related to the increase of revenue at HomeServices due to acquisitions in late 1999.

The following data represents sales from MidAmerican Energy:

Regulated and Non-Regulated Gas Supplied
 (Thousands of MMBtus) ....................    174,385     138,387

MidAmerican Energy electricity retail sales increased for the year ended December 31, 2000 from the same period in 1999 due to increased customers and non-weather related sales partially offset by more moderate temperatures. Electricity wholesale sales decreased for the year ended December 31, 2000 from the same period in 1999 due to a lower power plant output primarily from the Cooper Nuclear Station which results in lower energy available for resale. Gas supplied increased due to an increase in customers, an increase in heating degree days and an increase in trading activity of non-regulated sales.

The following data represents the supply and distribution operations in the United Kingdom:

Electricity Distributed (GWh) ..............   16,350     15,943
Gas Supplied (Thousands of MMBtus) .........   51,035     48,435

The increase in electricity supplied for the year ended December 31, 2000 was due primarily to the increase in volumes for customers outside of the franchise area. The increase in electricity distributed for the year ended December 31, 2000 was due to changes in demand in the franchise area. The increase in gas supplied in 2000 from 1999 reflected higher volume in the industrial and commercial markets.

Pro forma interest and other income for the year ended December 31, 2000 was $114.4 million compared with $145.4 million for the same period in 1999. The decrease was due primarily to the reduced interest income resulting from lower cash balances, lower dividends from TPL and gains on other asset sales in 1999, partially offset by proceeds of Company-owned life insurance of $7.5 million received in 2000.

The 1999 gain on non-recurring items resulted from the sale of approximately 6.74 million shares of McLeodUSA Class A common stock, through a secondary offering by McLeodUSA, at $55.625 per share. Proceeds from the sale exceeded $375 million, with a resulting after-tax gain to the Company of approximately $47.1 million.

46

As a result of the sales of the Coso Joint Ventures geothermal projects previously owned by the Company, and an interest in CE Gen, the Company recorded a gain of $20.2 million in the first quarter of 1999.

In the fourth quarter of 1999, the Company recorded a pre-tax gain of $40.3 million relating to insurance proceeds received from an arbitration settlement between Himpurna California Energy Ltd. and Patuha Power Ltd., former subsidiaries of the Company, and P.T. PLN (Persero), an Indonesian national electric utility.

Pro forma cost of sales for the year ended December 31, 2000 was $3,029.7 million compared with $2,398.6 million for the same period in 1999, an increase of 26.3%. The increase related to increased sales at MidAmerican Energy and HomeServices.

Pro forma operating expense for the year ended December 31, 2000 was $1,123.6 million compared with $1,115.8 million for the same period in 1999. The increase primarily relates to the increase of operating expenses at HomeServices due to acquisitions in late 1999.

Pro forma depreciation and amortization for the year ended December 31, 2000 was $479.6 million compared with $462.0 million for the same period in 1999. The increase was primarily due to higher depreciation at CE Electric UK primarily due to higher production at CE Gas Holdings, the Company's United Kingdom gas exploration subsidiary.

Pro forma interest expense, less amounts capitalized, for the year ended December 31, 2000 was $398.1 million compared with $447.0 million for the same period in 1999, a decrease of 10.9%. This decrease was due to the repayment of the 9.5% Senior Notes in 1999 and other reduced indebtedness and an increase in capitalized interest related to the construction of the Casecnan, Cordova and Zinc projects.

The loss on non-recurring items of $7.6 million in the period from January 1, 2000 through March 13, 2000 represents the costs related to the Company's acquisition by a private investor group.

Pro forma tax expense for the year ended December 31, 2000 was $81.6 million compared with $89.4 million for the same period in 1999. The decrease was due primarily to lower pretax income in 2000.

Pro forma minority interest for the year ended December 31, 2000 was $104.3 million compared with $101.9 million for the same period in 1999. Minority interest included the dividends on the $455 million of Company-obligated mandatorily redeemable preferred securities of subsidiary trusts.

Pro forma net income for the year ended December 31, 2000 was $124.9 million compared with $138.3 million for the same period in 1999.

LIQUIDITY AND CAPITAL RESOURCES

The Company has available a variety of sources of liquidity and capital resources, both internal and external. These resources provide funds required for current operations, construction expenditures, debt retirement and other capital requirements. The Company may from time to time seek to retire its outstanding debt through cash purchases in the open market, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, the Company's liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

The Company's cash and cash equivalents were $662 million at September 30, 2002, compared to $387 million at December 31, 2001. Each of the Company's direct or indirect subsidiaries is organized as a legal entity separate and apart from the Company and its other subsidiaries. Pursuant to separate financing agreements at each subsidiary, the assets of each subsidiary may be pledged or encumbered to support or otherwise provide the security for their own project or subsidiary debt. It should not be assumed that any asset of any subsidiary of the Company will be available to satisfy the obligations of the Company or any of its other subsidiaries; provided, however, that unrestricted cash or other assets which are available for distribution may, subject to applicable law and the terms of financing arrangements for such parties, be advanced, loaned, paid as dividends or otherwise distributed or contributed to the Company or affiliates thereof.

47

The Company generated cash flows from operations of $683 million for the nine months ended September 30, 2002, compared with $791 million for the same period in 2001. The decrease was primarily due to timing of changes in working capital activities, partially offset by positive impacts of the Kern River and real estate companies acquisitions.

The remaining increase to cash and cash equivalents is primarily due to the issuances of convertible preferred stock, trust preferred securities and subsidiary and project debt and cash proceeds from sale of assets, partially offset by the Kern River and Northern Natural Gas acquisitions, purchase of convertible preferred securities, repayment of subsidiary and project debt and capital expenditures for operating and construction projects.

In addition, the Company recorded separately restricted cash and investments of $63.9 million and $54.8 million at September 30, 2002, and December 31, 2001, respectively. The restricted cash balance as of September 30, 2002, is comprised primarily of amounts deposited in restricted accounts which is reserved for the service of debt obligations.

OTHER INVESTMENTS

On March 27, 2002, a newly formed subsidiary of the Company invested $275 million in Williams in exchange for shares of 9 7/8% cumulative convertible preferred stock of Williams. In connection with this investment, the Company issued $275 million of no par, zero coupon convertible preferred stock to Berkshire Hathaway. Dividends on the Williams' preferred stock are scheduled to be received quarterly, and commenced on July 1, 2002. This investment is accounted for under the cost method. The Company is aware that there have been public announcements that Williams' financial condition has deteriorated as a result of, among other factors, reduced liquidity. The Company had not recorded an impairment on this investment as of September 30, 2002, and is monitoring the situation.

DEBT ISSUANCES AND REDEMPTIONS

On February 8, 2002, MidAmerican Energy issued $400 million of 6.75% medium-term notes due in 2031.

Of this amount, $13.3 million of preferred securities were redeemed at 100% of the principal amount plus accrued dividends, and the remaining $13.4 million was redeemed at 103.9% of the principal amount plus accrued dividends.

On June 21, 2002, Kern River closed on a bank loan facility providing for aggregate loans of up to $875 million to be used for the construction of the Kern River 2003 Expansion Project. The facility, which matures 15 years after the 2003 Expansion Project commences operation, has a variable interest rate which increases over the term of the facility from 1.375% to 4.5% over LIBOR. Kern River had drawn $385 million on this facility as of September 30, 2002. In connection with this facility, the Company guaranteed the completion of the 2003 Expansion Project as described below in "Kern River's 2003 Expansion Project Financing."

REAL ESTATE COMPANIES 2002 ACQUISITIONS

In 2002, HomeServices separately acquired three real estate companies for an aggregate purchase price of approximately $100.0 million, net of cash acquired, plus working capital and certain other adjustments. For the year ended December 31, 2001, these real estate companies had combined revenue of approximately $356.0 million on 42,000 closed sides representing $13.7 billion of sales volume. Additionally, HomeServices is obligated to pay a maximum earnout of $18.5 million calculated based on 2002 financial performance measures. These purchases were financed using HomeServices' $65.0 million revolving credit facility and the Company's corporate revolver for $40.0 million, which was contributed to HomeServices as equity. The Company is in the process of completing the allocation of the purchase prices to the assets and liabilities acquired.

CALENERGY GAS HOLDING DISPOSAL

In May 2002, CE Gas Holdings, an indirect wholly owned subsidiary of the Company, completed the sale of several of its U.K. natural gas assets to Gaz de France for (pounds sterling)137.0 million (approximately $200.0 million). CE Gas Holdings sold four natural gas-producing fields located in the southern basin of the U.K. North Sea including Anglia, Johnston, Schooner and Windermere. The transaction also included the sale of rights in four gas fields in development and construction and three exploration blocks owned by CE Gas Holdings.

ACCOUNTS RECEIVABLE SOLD

In 1997, MidAmerican Energy entered into a revolving agreement, which expired on October 29, 2002, to sell all of its right, title and interest in the majority of its billed accounts receivable to MidAmerican Energy Funding Corporation, a special purpose entity established to purchase accounts receivable from MidAmerican Energy. MidAmerican Energy Funding Corporation in turn sold receivable interests to outside investors. In consideration for the sale, MidAmerican Energy received cash and a subordinated note, bearing interest at 8%, from MidAmerican Energy Funding Corporation. As of September 30, 2002, the revolving cash balance was $36.0 million and the amount outstanding under the subordinated note was $89.2 million. The agreement was structured as a true sale, under which the creditors of MidAmerican Energy Funding Corporation were entitled to be satisfied out of the assets of MidAmerican Energy Funding Corporation prior to any value being returned to MidAmerican Energy or its creditors. Therefore, the accounts receivable sold are not reflected on the Company's consolidated balance sheets. As of September 30, 2002, $126.0 million of accounts receivable, net of reserves, were sold under the agreement. MidAmerican Energy did not extend or replace this agreement.

CONSTRUCTION

MIDAMERICAN ENERGY

MidAmerican Energy's primary need for capital is for utility construction expenditures. For the first nine months of 2002, utility construction expenditures totaled $228.8 million, including allowance for funds used during construction, or capitalized financing costs, and Quad Cities Station nuclear fuel purchases. All such expenditures were met with cash generated from utility operations.

Forecasted MidAmerican Energy utility construction expenditures, including allowances for funds used during construction are $382.0 million for 2002 and $1.614 billion for 2003 through 2006. Capital expenditure needs are reviewed regularly by management and may change significantly as a result of such reviews.

MidAmerican Energy has announced plans to construct an electric generating plant, the Greater Des Moines Energy Center, in Iowa. The plant will provide service to regulated retail electricity customers and be included in MidAmerican Energy's regulated rate base in Iowa, Illinois and South Dakota. Wholesale sales may also be made from the plant to the extent the power is not needed for regulated retail service. The plant will be a 540 MW (500 MW based on expected accreditation) natural gas-fired plant with an estimated cost of $415.0 million. MidAmerican Energy will own 100% of the plant and will operate it. The

49

plant will be operated in simple cycle mode during 2003 and 2004, with combined cycle operation commencing in 2005. MidAmerican Energy commenced construction of the plant in 2002 following receipt of two orders from the IUB. The first order authorized construction of the plant. The second order, issued May 29, 2002, specified the principles that will apply to the plant over its life for purposes of Iowa ratemaking and was sought by MidAmerican Energy to limit regulatory risk.

MidAmerican Energy presently expects that all utility construction expenditures through 2007 will be met with the issuance of long-term debt and cash generated from utility operations, net of dividends. The actual level of cash generated from utility operations is affected by, among other things, economic conditions in the utility service territory, weather and federal and state legislation and regulatory actions.

KERN RIVER'S 2003 EXPANSION PROJECT FINANCING

On July 17, 2002, Kern River received approval from the FERC to construct, own and operate the 2003 Expansion Project. The 2003 Expansion Project will loop most of Kern River's existing mainline, construct three new compressor stations and upgrade or modify Kern River's six existing compressor stations. The 2003 Expansion Project, which is expected to be completed and operational by May 2003, will increase Kern River's capacity by approximately 900mmcf/day. Service will be provided under long-term contracts subject to incremental rates. The estimated cost of the expansion is approximately $1.2 billion, which will be financed with 70% debt and 30% equity, consistent with Kern River's existing capital structure, the application for the FERC approval described above and the limitations contained in the indenture for Kern River's existing secured senior notes.

Construction will initially be funded with the proceeds of an $875.0 million credit facility entered into by Kern River on June 21, 2002, until 70% of the projected capitalized costs of the 2003 Expansion Project has been spent. The final 30% of the capitalized costs of the 2003 Expansion Project will be funded with equity from the Company. The credit facility is structured as a two-year construction facility followed by a term loan with a final maturity 15 years after completion of the 2003 Expansion Project. However, Kern River presently intends to refinance the credit facility through a bond offering or other capital markets transaction following completion of the 2003 Expansion Project. Prior to completion of the 2003 Expansion Project, the credit facility lenders will have limited recourse to Kern River and its assets and cash flow, and will have recourse to the Company's completion guarantee described below. Following completion of the 2003 Expansion Project, until such time as the Kern River credit facility is refinanced, the lenders under the credit facility will share equally and ratably with the existing Kern River senior secured noteholders in all of the collateral pledged to such senior secured noteholders.

Pursuant to the Company's completion guarantee, it has guaranteed that "completion" of the 2003 Expansion Project will occur on or prior to the earliest of any abandonment by Kern River of the project, the occurrence of certain other acceleration events and June 30, 2004. The potential acceleration events include any downgrading of the Company's public debt rating to below investment grade by either S&P or Moody's unless a satisfactory substitute guarantor assumes the Company's obligations under the completion guarantee within 60 days after any such downgrade; Berkshire Hathaway ceasing to own at least a majority of the outstanding capital stock of the Company; and certain other customary events of default by the Company. In the completion guarantee, the Company has also agreed to cause capital contributions to be made to Kern River in a minimum aggregate amount of at least $375 million by June 30, 2004 or upon any earlier event of abandonment of the project. For purposes of the Company's completion guarantee, the term "completion" is defined in the Kern River credit agreement to mean satisfaction of a number of conditions, the most significant of which include the requirements that the 2003 Expansion Project be substantially complete and operable and able to permit Kern River to perform its obligations under all of the long-term firm gas transportation service agreements entered into in connection with the 2003 Expansion Project; that the shippers under such agreements shall have begun to incur the obligation to pay reservation fees thereunder; and that the FERC shall have authorized Kern River to begin collecting rates under its tariff and its shipper agreements; provided that the 2003 Expansion Project shall still be deemed to have been completed if it is less than substantially complete but it demonstrates at least 80% design capacity and Kern River's debt service coverage ratios as defined in its senior secured note indenture are not less than 1:55 to 1:0. There are a number of other conditions to

50

completion, including requirements that all conditions to completion of the expansion contained in Kern River's senior secured note indenture be satisfied and all of Kern River's obligations under its credit agreement then share pari passu in all collateral available to Kern River's senior secured noteholders. The Company's completion guarantee shall terminate upon the earlier of completion of the 2003 Expansion Project or repayment in full of all obligations under the Kern River credit facility.

ZINC RECOVERY PROJECT

CalEnergy Minerals LLC, our indirect wholly owned subsidiary, is constructing the Zinc Recovery Project. The Zinc Recovery Project is designed to have a capacity of approximately 30,000 metric tons per year, and commenced initial commercial operations in 2002. We expect the Zinc Recovery Project to be at 100% production in mid-2003. Total project costs of the Zinc Recovery Project are expected to be approximately $244.0 million, net of settlement proceeds from a dispute with the contractor, which is being funded by $140.5 million of debt and the balance from funds provided by the Company. The Zinc Recovery Project has incurred $213.9 million, net of settlement proceeds from a dispute with the contractor, of such costs through September 30, 2002.

DEVELOPMENT ACTIVITY

MidAmerican Energy has announced plans to develop a 750 MW super- critical-temperature, coal-fired plant fueled with Powder River low-sulfur coal in Pottawattamie County, Iowa. If constructed, MidAmerican Energy will operate the plant and expects to own 450 MW of the plant. Municipal, cooperative and public power utilities will own the remainder, which is a typical ownership arrangement for large baseload plants in Iowa. MidAmerican Energy's investment in the plant is projected to be approximately $785.0 million, including the cost of related transmission facilities, taxes and allowance for funds used during construction. The plant will provide service to regulated customers and be included in MidAmerican Energy's regulated rate base in Iowa, Illinois and South Dakota. Wholesale sales may also be made from the plant to the extent the power is not needed for regulated retail service. MidAmerican Energy has made a filing with the IUB for a certificate to construct this plant and has made a filing with the IUB for approval of ratemaking principles for this plant during the fourth quarter of 2002. The development of this plant is subject to obtaining environmental and other required permits, as well as to receiving orders from the IUB approving construction of the plant and associated transmission facilities and establishing ratemaking principles which are satisfactory to MidAmerican Energy.

The Company's subsidiary, Fox Energy Company LLC, is developing a 635 net MW gas fired power generating facility in Kaukanna, Outagamie County, Wisconsin. A subsidiary of TransAlta Corporation has agreed to participate in the development of this project at a level of 50% and has an option to own 50% of the project. The Company's subsidiary, CE Obsidian Energy LLC, or Obsidian, is developing a 185 net MW geothermal facility in Imperial Valley, California, known as Salton Sea VI. An affiliate of El Paso Corporation, or El Paso, has elected to participate in the ownership and development of this project at a level of 50%.

The Company is actively seeking to develop, construct, own and operate additional new energy projects, both domestically and internationally, the completion of any of which is subject to substantial risk. Development can require the Company to expend significant sums for preliminary engineering, permitting, fuel supply, resource exploration, legal and other expenses in preparation for competitive bids which the Company may not win or before it can be determined whether a project is feasible, economically attractive or capable of being financed. Successful development and construction is contingent upon, among other things, negotiation on terms satisfactory to the Company of engineering, construction, fuel supply, sales contracts and, if the Company intends to own less than 100% of the project, joint venture or similar agreements, with other project participants, receipt of required governmental permits and consents and timely implementation of construction. There can be no assurance that development efforts on any particular project, or the Company's development efforts generally, will be successful. See "Risk Factors."

COOPER NUCLEAR STATION CONTRACT RESTRUCTURING

On July 31, 2002, MidAmerican Energy and the NPPD signed an agreement on the restructuring of the power purchase contract for Cooper Nuclear Station. Under the terms of the restructured contract, MidAmerican Energy will pay NPPD through December 31, 2004, a scheduled amount per unit for 380 MW of the accredited capacity of Cooper Nuclear Station and a minimum of approximately 1.2 million MWh in the last five months of 2002 and approximately 2.5 million MWh in each of 2003 and 2004. NPPD also paid MidAmerican Energy $39.1 million on August 1, 2002.

In December 2000, MidAmerican Energy ceased contributing decommissioning funds to NPPD and maintained a separate fund for estimated Cooper Nuclear Station decommissioning costs. Through July 31, 2002, $18.3 million had been accrued and retained by MidAmerican Energy in this separate fund. In conjunction with the power purchase contract restructuring, MidAmerican Energy is recognizing the $39.1 million cash payment and the $18.3 million previously accrued for decommissioning into income based on the estimated energy expected to be received for the remainder of the contract.

Finally, both parties agreed to release each other from any and all claims, past or present, each might have under the power purchase contract prior to being restructured and file to dismiss the litigation currently pending in U.S. District Court.

Under the terms of MidAmerican Energy's power purchase contract with NPPD prior to its restructuring, MidAmerican Energy paid NPPD one-half of the fixed and operating costs of Cooper Nuclear Station, excluding depreciation but including debt service, and MidAmerican Energy's share of the nuclear fuel cost, including Department of Energy disposal fees, based on energy delivered. In addition, prior to December 2000, MidAmerican Energy contributed toward payment of one-half of Cooper Nuclear Station's project decommissioning costs based on an assumed 2004 shutdown of the plant. These obligations ceased pursuant to the restructuring of the power purchase contract for Cooper Nuclear Station.

OBLIGATIONS AND COMMITMENTS

The Company has contractual obligations and commercial commitments that may affect its financial condition. Based on management's assessment of the underlying provisions and circumstances of the material contractual obligations and commercial commitments of the Company, including material off-balance sheet and structured finance arrangements, there is no known trend, demand, commitment, event or uncertainty that is reasonably likely to occur which would have a material effect on the Company's financial condition or results of operations. The following tables identify material obligations and commitments as of December 31, 2001:

As of September 30, 2002, Northern Natural Gas had $13.8 million of obligations to deliver 4.0 Bcf of natural gas in 2002 and $46.0 million of obligations to deliver 12.2 Bcf of natural gas in 2003. The obligations are revalued based on market prices for natural gas, with changes in value included in the statement of operations. In 2002, Northern Natural Gas entered into natural gas commodity price swaps and index basis swaps to effectively fix the deferred obligation balance. Any further changes in the market value of the deferred obligations will be offset by a corresponding change in the opposite direction in the market value of the swaps.

Other than the delivery of natural gas issue described above, the issuance of Company-obligated mandatorily redeemable preferred securities of subsidiary trust in connection with the Northern Natural Gas and Kern River acquisitions as described in note 2 in the notes to the consolidated financial statements for the nine months ended September 30, 2002, and the issuance of long-term debt as described in note 8 in the notes to the consolidated financial statements for the nine months ended September 30, 2002, there have been no other material changes to the obligations and commitments as described in the Annual Report on Form 10-K for the year ended December 31, 2001.

OFF-BALANCE SHEET ARRANGEMENTS

The Company has certain investments that are accounted for under the equity method in accordance with GAAP. Accordingly, an amount is recorded on the Company's balance sheet as an equity investment and is increased or decreased for the Company's pro-rata share of earnings or losses, respectively, less any dividend distribution from such investments.

As of September 30, 2002, the Company's investments which are accounted for under the equity method had an aggregate $1,060.2 million of debt and $70.3 million in outstanding letters of credit. As of September 30, 2002, the Company's pro-rata share of the debt was $524.9 million and was non-recourse to the Company, except for $138.8 million of such debt which the Company has guaranteed on the Salton Sea Funding Series F Bonds and which was included in the Company's consolidated balance sheet at September 30, 2002. (See note 8 to the notes to the consolidated financial statements for the year ended December 31, 2001 included in this prospectus for further discussion). The Company's pro-rata share of the outstanding letters of credit was $35.1 million as of September 30, 2002. The Company is generally not required to support the debt service obligations of these investments. However, default with respect to this non-recourse debt could result in a loss of invested equity.

STANDARD ELECTRICITY MARKET DESIGN

On July 31, 2002, the FERC issued a notice of proposed rulemaking with respect to Standard Market Design for the electric industry. The FERC has characterized the proposal as portending "sweeping changes" to the use and expansion of the interstate transmission and the wholesale bulk power systems in the United States. The proposal includes numerous proposed changes to the current regulation of

53

transmission and generation facilities designed "to promote economic efficiency" and replace the "obsolete patchwork we have today," according to the FERC Chairman. The final rule, if adopted as currently proposed, would require all public utilities operating transmission facilities subject to the FERC jurisdiction to file revised open access transmission tariffs that would require changes to the basic services these public utilities currently provide. The proposed rule may impact the pricing of MidAmerican Energy's electricity and transmission products. The FERC does not envision that a final rule will be fully implemented until September 30, 2004. The Company is still evaluating the proposed rule and the Company believes that the final rule could vary considerably from the initial proposal. Accordingly, the Company is presently unable to quantify the likely impact of the proposed rule on the Company and its subsidiaries.

DOMESTIC GAS RATES MATTERS

On March 15, 2002, MidAmerican Energy made a filing with the IUB requesting an increase in rates of approximately $26.6 million for its Iowa retail natural gas customers. As part of the filing, MidAmerican Energy requested an interim rate increase of approximately $20.4 million annually. On June 12, 2002, the IUB issued an order granting an interim rate increase of approximately $13.8 million annually, effective immediately and subject to refund with interest. On July 15, 2002, MidAmerican Energy and the Office of Consumer Advocate filed a proposed settlement agreement with the IUB. The settlement agreement, which was approved by the IUB on November 8, 2002, provides for an increase in rates of $17.7 million annually for MidAmerican Energy's Iowa retail natural gas customers and freezes such rates for two years after the date the IUB approves tariffs implementing the settlement agreement. MidAmerican Energy implemented the new rates effective November 25, 2002.

PHILIPPINES REGULATORY MATTERS

The Philippine Congress has passed the Electric Power Industry Reform Act of 2001, which is aimed at restructuring the Philippine power industry, privatization of the NPC and introduction of a competitive electricity market, among other initiatives. The implementation of the bill may have an impact on the Company's future operations in the Philippines and the Philippines power industry as a whole, the effect of which is not yet determinable and estimable.

In connection with an interagency review of approximately 40 independent power project contracts in the Philippines, the Casecnan Project (along with four other unrelated projects) has reportedly been identified as raising legal and financial questions and, with those projects, has been prioritized for renegotiation. The Company's subsidiaries' Upper Mahiao, Malitbog, and Mahanagdong projects, which, together with the Casecnan Project, collectively referred to as the Philippine Projects, have also reportedly been identified as raising financial questions. No written report has yet been issued with respect to the interagency review, and the timing and nature of steps, if any, that the Philippine Government may take in this regard are not known. To the extent disputes arise under the Philippine Projects' agreements with respect to the Philippines Projects' obligations, rights and remedies thereunder, such disputes will be determined by international arbitration in a neutral forum conducted in accordance with the rules of the International Chamber of Commerce or UNCITRAL, as applicable.

Representatives of CE Casecnan together with certain current and former Philippine government officials, also have been requested to appear, and have appeared, before a Philippine Senate committee which has independently raised questions and made allegations with respect to the Casecnan Project's tariff structure and implementation. No further hearings are scheduled at this time.

NEW ACCOUNTING PRONOUNCEMENTS AND REPORTING ISSUES

In August 2001, the Financial Accounting Standards Board, or FASB, issued SFAS No. 143, "Accounting for Asset Retirement Obligations". SFAS No. 143 requires recognition on the balance sheet of legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or normal operation of such assets. Additionally, at the time an asset retirement obligation, or ARO, is recognized, an ARO asset of the same amount is recorded and depreciated. This pronouncement is effective for fiscal years beginning after June 15, 2002. The Company is evaluating the impact that adoption of this standard will have on its consolidated financial statements.

54

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", which addresses the financial accounting and reporting for the impairment or disposal of long-lived assets. The adoption of SFAS No. 144 on January 1, 2002, did not have any impact on the Company's consolidated financial statements.

The Emerging Issues Task Force, or EITF, recently issued EITF Issue No. 02-3, "Recognition and Reporting of Gains and Losses on Energy Trading Contracts Under Issues No. 98-10 and 00-17." In accordance with EITF No. 02-3, all gains and losses on energy trading contracts must be reported net on the income statement, effective for reporting periods ending after July 15, 2002, with all prior periods presented being reclassified to a consistent presentation. MidAmerican Energy's nonregulated wholesale gas and electric marketing activities qualify as "energy trading" contracts under the guidance of EITF No. 98-10. In accordance with EITF Issue No. 02-3, effective September 30, 2002, for MidAmerican Energy, all trading revenues are reported net of the cost of such sales. Previously, such amounts were recorded gross. All prior periods have been reclassified to conform to the net presentation.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to market risk, including changes in the market price of certain commodities and interest rates. To manage the price volatility relating to these exposures, the Company enters into various financial derivative instruments. Senior management provides the overall direction, structure, conduct and control of the Company's risk management activities, including the use of financial derivative instruments, authorization and communication of risk management policies and procedures, strategic hedging program guidelines, appropriate market and credit risk limits, and appropriate systems for recording, monitoring and reporting the results of transactional and risk management activities.

During the nine months ended September 30, 2002, the Company issued long-term debt as described in note 8 of our notes to the consolidated financial statements for the nine months ended September 30, 2002 and assumed additional debt with the acquisitions of Northern Natural Gas and Kern River. However, the Company does not believe it has any material change in regard to exposure to interest rate risk.

Refer to note 16 of our notes to the consolidated financial statements for the year ended December 31, 2001 included in this prospectus for discussion on derivatives used to hedge price risk. The Company's exposure to commodity price risk has not changed materially from December 31, 2001.

BUSINESS

GENERAL

MidAmerican Energy Holdings Company is a United States-based privately owned global energy company. Our subsidiaries' principal businesses are regulated electric and natural gas utilities, regulated interstate natural gas transmission and electric power generation. Our operations are organized on seven distinct platforms which we refer to as: MidAmerican Energy, Northern Natural Gas, Kern River, CE Electric UK (which includes Northern Electric and Yorkshire Electricity), CalEnergy Generation-Domestic, CalEnergy Generation-Foreign and HomeServices. Through six of these platforms, we own and operate a combined electric and natural gas utility company in the United States, two natural gas pipeline companies in the United States, two electricity distribution companies in the United Kingdom, and a diversified portfolio of domestic and international independent power projects. We also own the second largest residential real estate brokerage firm in the United States.

Financial information for each of our seven operating platforms is contained in note 22 to our consolidated financial statements for the year ended December 31, 2001 and note 14 to our consolidated financial statements for the nine month period ended September 30, 2002 included in this prospectus. Financial information for Kern River and Northern Natural Gas is included in note 14 to our consolidated financial statements for the nine month period ended September 30, 2002, from their respective dates of acquisition. Financial information for our utility platforms may differ from the amounts included in the notes to the financial statements due to the effects of fair value adjustments associated with our acquisition of these entities. The following is a chart of our operating platforms and the principal lines of business in which they are engaged:

Our senior unsecured obligations have received investment grade ratings of Baa3, BBB-- and BBB from Moody's Investors Service Inc., Standard & Poors Ratings Services and Fitch, Inc., respectively. Our utility subsidiaries also have investment grade ratings by Moody's, S&P and Fitch, respectively:
MidAmerican Energy (A3, A- and A-), Northern Natural Gas (Baa2, A- and BBB+), Kern River (A3, A- and A-), Northern Electric (A3, A- and A) and Yorkshire Electricity (A3, A- and A), respectively. However, these ratings are subject to change.

We initially incorporated in 1971 under the laws of the State of Delaware. We were reincorporated in 1999 in Iowa, at which time we changed our name from CalEnergy Company, Inc. to MidAmerican Energy Holdings Company.

STRATEGY

Our business strategy is focused upon the successful operation, management and growth of our diversified portfolio of energy assets and on the pursuit of strategic utility acquisitions and selected other investment opportunities, principally in the United States. As a privately owned company, we are able to focus on long-term risk-adjusted cash flow returns from our businesses. We seek to manage and operate our energy assets such that their cost structure makes us a low-cost provider of energy and energy services.

56

In order to implement this strategy, we plan to:

PURSUE OPERATING EFFICIENCIES AND INTERNAL INVESTMENT OPPORTUNITIES IN OUR BUSINESSES, WHILE MAINTAINING QUALITY AND RELIABILITY OF SERVICE. Our management philosophy emphasizes the efficient operation of our businesses through strict attention to the operational performance of our assets, continuous review and implementation of cost reduction initiatives and the active pursuit of opportunities to earn reasonable returns by making incremental capital investments within our existing operations. Following each of our utility acquisitions, we have implemented operational improvements and cost reductions that have enhanced asset performance and service reliability. These and other initiatives have helped us to pursue our goal of being a low-cost provider of energy and energy services to our customers and have strengthened our competitive position in the marketplace, while also increasing the returns on our investments. In addition, we have worked closely and successfully with customers and with regulatory and legislative authorities to ensure that our business initiatives are consistent with our obligations to serve customers and with the requirements of the regulatory regimes under which we operate. We have identified and are proceeding with a number of significant capital investment opportunities that we believe offer attractive risk-adjusted returns. These opportunities include a $1.2 billion program to expand MidAmerican Energy's base of electric generation facilities in Iowa and a $1.2 billion investment in Kern River's 2003 Expansion Project.

GROW AND DIVERSIFY THROUGH ACQUISITIONS OF HIGH QUALITY REGULATED UTILITY BUSINESSES. We believe that well managed regulated utility businesses can provide a stable cash flow profile and a reasonable risk-adjusted equity return to their owners. Our acquisitions of Northern Electric in 1997 and MidAmerican Energy in 1999 provided us with specialized skills and expertise, particularly in operations and regulatory affairs, which have enhanced our competitive position and positioned us favorably for future growth in our targeted sectors. In the past fifteen months, we completed three acquisitions of utility operating companies, Yorkshire Electricity, Kern River and Northern Natural Gas, each of which has added substantially to our base of utility operating assets and cash flows. We believe that these acquisitions helped us achieve additional diversification of our utility business with respect to sources of cash flow, types of utility operations, geography and regulatory regimes.

CAPITALIZE ON CHANGE IN OUR INDUSTRY AND ON OUR SUPERIOR ACCESS TO CAPITAL IN ORDER TO MAKE ATTRACTIVE INVESTMENTS. The global energy markets, particularly those in the United States, are experiencing a period of significant change due to various factors, including the macroeconomic environment, fluctuating commodity prices, regulatory and legislative developments and financial restructurings by many market participants. We and our shareholders believe that such an environment provides opportunities for disciplined companies with access to investment capital to achieve reasonable risk-adjusted returns by acquiring high quality companies and assets at reasonable prices. Warren Buffett, Chairman of the Board and Chief Executive Officer of Berkshire Hathaway, has publicly stated that we are a core holding of Berkshire Hathaway and are expected to be its principal vehicle for investments in the energy sector. In 2002 to date, we completed two acquisitions of interstate natural gas transmission pipelines, which we funded with a majority of the proceeds of Berkshire Hathaway's investment in $1.273 billion of our trust preferred securities and $402 million of our zero coupon convertible preferred stock, all of which is subordinated to our senior indebtedness. We believe that our ability to successfully negotiate and complete these acquisitions was facilitated by our access to capital from Berkshire Hathaway and that there continue to be opportunities in the current environment to make additional acquisitions that further enhance our business mix, risk profile, capitalization and investment returns.

ENHANCE OUR INVESTMENT GRADE CREDIT PROFILE AND THAT OF OUR SUBSIDIARIES. Our financing strategy is focused on capitalizing and managing our utility subsidiaries in a manner consistent with maintenance of strong credit ratings, thereby supporting our credit profile with more predictable underlying cash flows from these subsidiaries. This strategy is driven by our belief that strong credit ratings allow us to minimize our financing costs over the long term and to optimize our investment returns, while also retaining the financial flexibility to pursue attractive capital investment opportunities as and when they are available. Our strategy is to finance our operating subsidiaries with debt that in almost all cases is non-recourse to us, which has allowed us to reduce financing costs by taking advantage of the stable, investment grade characteristics of our subsidiaries' utility assets.

57

MAINTAIN PRUDENT FINANCIAL AND RISK MANAGEMENT POLICIES AND PRACTICES. Through our focus on regulated utility businesses, we strive to minimize the underlying risks of our portfolio of assets. Substantially all of our net owned MW in our non-utility power generation business have long-term (greater than one year) contracts for the sale of their energy and/or capacity, and substantially all of these assets are financed by non-recourse project finance debt. We seek to limit our exposure to movements in the commodity prices of energy products and are not a significant trader of energy commodities. Our activities in the marketing and supply of energy to customers outside of our regulated customer base are not a material part of our business and are conducted pursuant to closely monitored risk management policies and practices that are intended to minimize our exposure to fluctuations in energy commodity prices and to counterparty credit risk. A core tenet of our acquisition and investment philosophy is that we will only pursue opportunities that meet our strict requirements for an acceptable risk profile and attractive potential cash flow returns. If we do not believe that such opportunities are available, we prefer to reduce our acquisition activities and focus on the optimization of our existing portfolio rather than pursue growth by accepting greater risks or inferior returns.

MIDAMERICAN ENERGY

MidAmerican Energy is the largest energy company headquartered in Iowa. MidAmerican Energy is principally engaged in the business of generating, transmitting, distributing and selling electric energy and in distributing, selling and transporting natural gas. MidAmerican Energy distributes electricity at retail in Iowa, Illinois and South Dakota. It also distributes natural gas at retail in Iowa, Illinois, South Dakota and Nebraska. MidAmerican Energy's utility operations are providing regulated retail electric service to approximately 678,000 customers and regulated retail natural gas service to approximately 653,000 customers. MidAmerican Energy also provides competitive natural gas service in several Midwestern states and competitive electric service in Illinois and Ohio.

In addition to retail sales, MidAmerican Energy sells electric energy and natural gas to other utilities, marketers and municipalities outside of MidAmerican Energy's delivery system. These sales are referred to as wholesale sales. It also transports natural gas through its distribution system for a number of end-use customers who have independently secured their supply of natural gas.

MidAmerican Energy's electric and gas utility 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 Energy has a residential, agricultural, commercial and diversified industrial customer group, in which no single industry or customer accounted for more than 4% of its total 2001 electric operating revenues or 4% of its total 2001 gas operating margin. Among the primary industries served by MidAmerican Energy are those which are concerned with food products, the manufacturing, processing and fabrication of primary metals, real estate, farm and other non-electrical machinery, and cement and gypsum products.

For the nine months ended September 30, 2002, MidAmerican Energy derived approximately 67% of its gross operating revenues from its electric utility business, 28% from its gas utility business and 5% from its non-regulated business activities. For 2001, 2000 and 1999, the corresponding percentages were 56% electric, 37% gas and 7% non-regulated, 53% electric, 41% gas and 6% non-regulated and 67% electric, 32% gas and 1% non-regulated, respectively. The change in revenue mix is principally driven by changes in natural gas prices and seasonality.

There are seasonal variations in MidAmerican Energy's electric and gas businesses, which are principally related to the use of energy for air conditioning and heating. In 2001, 38% of MidAmerican Energy's electric utility revenues were reported in the months of June, July, August and September, and 59% of MidAmerican Energy's gas utility revenues were reported in the months of January, February, March and December.

ELECTRIC OPERATIONS

The electric utility industry continues to undergo regulatory change. Traditionally, prices charged by electric utility companies have been regulated by federal and state commissions and have been based on

58

cost of service. In recent years, changes have been occurring that move the electric utility industry toward a more competitive, market-based pricing environment. These changes may have a significant impact on the way MidAmerican Energy does business.

MidAmerican Energy manages its operations as four separate business units:
generation, energy delivery, transmission, and marketing and sales. The generation segment derives most of its revenue from the sale of regulated wholesale electricity and non-regulated wholesale and retail natural gas. The energy delivery segment derives its revenue principally from the delivery of regulated electricity and natural gas, while the transmission segment obtains most of its revenue from the sale of transmission capacity. The marketing and sales segment receives its revenue principally from non-regulated sales of natural gas and electricity.

For the year ended December 31, 2001, regulated electric sales by MidAmerican Energy by customer class were as follows: 20.6% were to residential customers, 15.3% were to small general service customers, 25.8% were to large general service customers, 7.3% were to other customers, and 31.0% were wholesale sales. For the year ended December 31, 2001, regulated electric sales by MidAmerican Energy by jurisdiction were as follows: 88.6% to Iowa, 10.6% to Illinois and 0.8% to South Dakota.

The annual hourly peak demand on MidAmerican Energy's electric system occurs principally as a result of air conditioning use during the cooling season. In July 2002, MidAmerican Energy recorded an hourly peak demand of 3,887 MW, which is 54 MW greater than MidAmerican Energy's previous record hourly peak of 3,833 MW set in 1999.

The following table sets out information concerning MidAmerican Energy's power generation facilities as of November 1, 2002:

(1) We operate all such power generation facilities other than Quad Cities Generating Station and Ottumwa Generation Station.

(2) Represents accredited net generating capability. Actual MW may vary depending on operating conditions and plant design. Net MW owned indicates ownership of accredited capacity for the summer of 2002 as approved by the Mid-Continent Area Power Pool (MAPP).

MidAmerican Energy's accredited net generating capability in the summer of 2002 was 4,724 MW, which included its 4,118 net MW owned and its accredited net MW capability pursuant to the restructured Cooper Nuclear Station power purchase agreement for a minimum guaranteed amount of energy from

59

any source and the Cordova power purchase agreement. Accredited net generating capability represents the amount of generation available to meet the requirements on MidAmerican Energy's energy system, including the net amount of capacity purchases less capacity sales from company-owned generation and generation under power purchase contracts. The net generating capability at any time may be less than it would otherwise be due to regulatory restrictions, fuel restrictions and generating units being temporarily out of service for inspection, maintenance, refueling or modifications.

MidAmerican Energy has announced plans regarding two electric generating plants in Iowa. Both plants would provide service to regulated retail electricity customers and be included in regulated rate base in Iowa, Illinois and South Dakota. Wholesale sales may also be made from the plants to the extent the power is not needed for regulated retail service.

The first plant, which is the Greater Des Moines Energy Center described above, will be a 540 MW (500 MW based on expected accreditation) natural gas-fired plant with an estimated cost of $415 million. MidAmerican Energy will own 100% of the plant and will operate it. The plant will be operated in simple cycle mode during 2003 and 2004, with combined cycle operation commencing in 2005. MidAmerican Energy commenced construction of the plant in 2002 following receipt of two orders from the IUB. The first order authorized construction of the plant. The second order, issued May 29, 2002, specified the principles that will apply to the plant over its life for purposes of Iowa ratemaking and was sought by MidAmerican Energy to limit regulatory risk.

The second plant is currently under development and is expected to be a 750 MW super-critical-temperature, coal-fired plant fueled with Powder River low-sulfur coal in Pottawattamie County, Iowa. If constructed, MidAmerican Energy will operate the plant and expects to own 450 MW of the plant. Municipal, cooperative and public power utilities will own the remainder, which is a typical ownership arrangement for large baseload plants in Iowa. MidAmerican Energy has made a filing with the IUB for a certificate to construct this plant and has made a filing with the IUB for approval of ratemaking principles for this second plant during the fourth quarter of 2002. The development of this plant is subject to obtaining environmental and other required permits, as well as to receiving orders from the IUB approving construction of the plant and associated transmission facilities and establishing ratemaking principles which are satisfactory to MidAmerican Energy.

MidAmerican Energy presently expects that all utility construction expenditures through 2007 will be met with the issuance of long-term debt and cash generated from utility operations, net of dividends. The actual level of cash generated from utility operations is affected by, among other things, economic conditions in the utility service territory, weather and federal and state legislation and regulatory actions.

MidAmerican Energy is interconnected with Iowa utilities and utilities in neighboring states and is involved in an electric power pooling agreement known as Mid-Continent Area Power Pool, or MAPP. MAPP is a voluntary association of electric utilities doing business in Minnesota, Nebraska, North Dakota and the Canadian provinces of Saskatchewan and Manitoba and portions of Iowa, Montana, South Dakota and Wisconsin. Its membership also includes power marketers, regulatory agencies and independent power producers. MAPP facilitates operation of the transmission system and is responsible for the safety and reliability of the bulk electric system.

In November 2001, MAPPCOR, the contractor to MAPP, sold its transmission-related assets to the Midwest Independent Transmission System Operator, Inc., or Midwest ISO. The Midwest ISO now has responsibility for administration of MAPP's Open-Access Transmission Tariff.

Each MAPP participant is required to maintain for emergency purposes a net generating capability reserve of at least 15% above its system peak demand. MidAmerican Energy's reserve margin at peak demand for 2002 was approximately 22%. However, significantly higher-than-normal temperatures during the cooling season could cause MidAmerican Energy's reserve to fall below the 15% minimum. If MidAmerican Energy fails to maintain the appropriate reserve, significant penalties could be contractually imposed by MAPP.

MidAmerican Energy's transmission system connects its generating facilities with distribution substations and interconnects with 14 other transmission providers in Iowa and five adjacent states. Under

normal operating conditions, MidAmerican Energy's transmission system is unconstrained and has adequate capacity to deliver energy to MidAmerican Energy's distribution system and to export and import energy with other interconnected systems.

In December 1999, the FERC issued Order No. 2000 establishing, among other things, minimum characteristics and functions for regional transmission organizations. Public utilities that were not a member of an independent system operator at the time of the order were required to submit a plan by which its transmission facilities would be transferred to a regional transmission organization. On September 28, 2001, MidAmerican Energy and five other electric utilities filed with the FERC a plan to create TRANSLink Transmission Company LLC, or TRANSLink, and to integrate their electric transmission systems into a single, coordinated system operating as a for-profit independent transmission company in conjunction with a FERC-approved regional transmission organization. On April 25, 2002, the FERC issued an order approving the transfer of control of MidAmerican Energy's and other utilities' transmission assets to TRANSLink in conjunction with TRANSLink's participation in the Midwest ISO. Additional state regulatory approval is required from states in which TRANSLink will be operating and those applications have not yet been filed. Once filed, MidAmerican Energy does not anticipate rulings in the state proceedings until some time in 2003. Transferring operation and control of MidAmerican Energy's transmission assets to other entities could increase costs for MidAmerican Energy; however, the actual impact of TRANSLink on MidAmerican Energy's future transmission costs is not yet known.

GAS OPERATIONS

For the year ended December 31, 2001, regulated gas sales by MidAmerican Energy, excluding transportation throughput, by customer class were as follows:
34.5% were to residential customers, 18.2% were to small general service customers, 1.5% were to large general service customers, 1.7% were to other customers, and 44.1% were wholesale sales. For the year ended December 31, 2001, regulated gas sales by MidAmerican Energy, excluding transportation throughput, by jurisdiction were as follows: 78.9% to Iowa, 10.5% to South Dakota, 9.8% to Illinois, and 0.8% to Nebraska.

MidAmerican Energy purchases gas supplies from producers and third party marketers. To ensure system reliability, a geographically diverse supply portfolio with varying terms and contract conditions is utilized for the gas supplies.

MidAmerican Energy has rights to firm pipeline capacity to transport gas to its service territory through direct interconnects to the pipeline systems of Northern Natural Gas, Natural Gas Pipeline Company of America, Northern Border Pipeline Company and ANR Pipeline Company. Firm capacity in excess of MidAmerican Energy's system needs, resulting from differences between the capacity portfolio and seasonal system demand, can be resold to other companies to achieve optimum use of the available capacity. Past IUB, and South Dakota Public Utilities Commission rulings have allowed MidAmerican Energy to retain 30% of Iowa and South Dakota margins, respectively, earned on the resold capacity, with the remaining 70% being returned to customers through a purchased gas adjustment clause as described below.

MidAmerican Energy's cost of gas is recovered from customers through purchased gas adjustment clauses. In 1995, the IUB gave initial approval of MidAmerican Energy's Incentive Gas Supply Procurement Program. Under the program, as amended, MidAmerican Energy is required to file with the IUB every six months a comparison of its gas procurement costs to an index-based and historical reference price. If MidAmerican Energy's costs of gas for the period are less or greater than an established tolerance band around the reference price, then MidAmerican Energy shares a portion of the savings or costs with customers. In October 2002, the IUB approved a one year extension of the program through October 31, 2003. A similar program is currently in effect in South Dakota through October 31, 2005. Since the implementation of the program, MidAmerican Energy has successfully achieved and shared savings with its natural gas customers.

MidAmerican Energy utilizes leased gas storage to meet peak day requirements and to manage the daily changes in demand due to changes in weather. The storage gas is typically replaced during the summer months. In addition, MidAmerican Energy also utilizes three liquefied natural gas plants and two propane-air plants to meet peak day demands.

61

MidAmerican Energy has strategically built multiple pipeline interconnections into several of its larger communities. Multiple pipeline interconnects create competition among pipeline suppliers for transportation capacity to serve those communities, thus reducing costs. In addition, multiple pipeline interconnects give MidAmerican Energy the ability to optimize delivery of the lowest cost supply from the various pipeline supply basins into these communities and increase delivery reliability. Benefits to MidAmerican Energy's system customers are shared with all jurisdictions through a consolidated purchased gas adjustment clause.

NORTHERN NATURAL GAS COMPANY

EXISTING FACILITIES AND BUSINESS

Northern Natural Gas is one of the largest interstate natural gas pipeline systems in the United States. It reaches from Texas to Michigan's Upper Peninsula and is engaged in the transmission and storage of natural gas for utilities, municipalities, other pipeline companies, gas marketers, industrial and commercial users and other end users. Northern Natural Gas' revenues are derived from the interstate transportation and storage of natural gas for third parties. Except for small quantities of natural gas owned for system operations, Northern Natural Gas does not own the natural gas that is transported through its system. Northern Natural Gas' transportation and storage operations are subject to a FERC-regulated tariff that is designed to allow it an opportunity to recover its costs together with a regulated return on equity.

Northern Natural Gas' system is comprised of two distinct areas, its traditional end-use and distribution market area at the northern end of the system, including delivery points in Michigan, Illinois, Iowa, Minnesota, Kansas, Nebraska, Wisconsin and South Dakota, which we refer to as the Market Area, and the natural gas supply and market area at the southern end of the system, including Kansas, Oklahoma, Texas and New Mexico, which we refer to as the Field Area. Northern Natural Gas' Field Area is interconnected with many interstate and intrastate pipelines in the national grid system. A majority of Northern Natural Gas' capacity in both the Market Area and the Field Area is dedicated to Market Area customers under long-term firm transportation contracts. Approximately 49% of Northern Natural Gas' capacity subject to firm transportation contracts is under contracts which extend beyond 2005.

Northern Natural Gas' strategic plan is focused on taking advantage of the system's bi-directional and relatively flexible natural gas transportation capabilities and its storage assets to maximize economic returns. A key component of this strategic plan is to build upon Northern Natural Gas' asset base located in the center of the North American natural gas grid by increasing flexibility through additional pipeline interconnects. Through existing interconnections, Northern Natural Gas' shippers have supply access to Canadian, Rocky Mountain, Hugoton, Anadarko and Permian supplies. Northern Natural Gas also expects to pursue selective pipeline expansions, storage service enhancement and improved utilization of existing systems. In addition, Northern Natural Gas is focused on utilizing its ability to transport both dry natural gas and processable natural gas to take advantage of opportunities presented by natural gas processing facility consolidations in the Mid-continent. Northern Natural Gas expects to be able to meet the expected demand growth in its Market Area with only modest investment in new facilities as a result of the flexibility in Northern Natural Gas' system. Furthermore, Northern Natural Gas' access to supply diversity is expected to provide it with a significant competitive advantage because of the ability of the system to provide shippers access to many sources of low cost natural gas.

Northern Natural Gas operates approximately 16,600 miles of natural gas pipelines which deliver approximately 5.0% of the total natural gas consumed in the United States. The Northern Natural Gas system is believed to be the largest in the United States as measured by pipeline miles and the eighth largest as measured by throughput. The pipeline system is powered by 92 transmission compressor stations with an aggregate of approximately 840,000 horsepower. Northern Natural Gas operates three natural gas storage facilities and two liquefied natural gas, or LNG, storage peaking units for a total storage capacity of 59 Bcf and peak delivery capability of over 1.3 Bcf/day. Northern Natural Gas' pipeline system is configured with approximately 3,500 receipt and delivery points (excluding farm taps) which are

62

integrated with the facilities of local distribution companies, or LDCs. Natural gas deliveries from Northern Natural Gas to the Market Area and Field Area totaled approximately 1.4 Tcf in 2001.

The northern portion of Northern Natural Gas' pipeline system transports natural gas primarily to end-user and local distributor markets in the Market Area. Customers consist of LDCs, municipalities, other pipeline companies, gas marketers and end-users. While approximately ten large LDCs account for the majority of Market Area volumes, Northern Natural Gas also serves numerous small communities through these large LDCs as well as municipalities or smaller LDCs and directly serves several large end-users. In 2001, approximately 85% of Northern Natural Gas' revenues were from capacity charges under firm transportation and storage contracts and approximately 85% of those revenues were from LDCs. In 2001, approximately 69% of Northern Natural Gas' revenues were generated from Market Area customer contracts. The following customers, all of whom were utility LDCs located in the Market Area, each accounted for approximately 10% or more of Northern Natural Gas' transportation revenues for the year ended December 31, 2001: Reliant Energy Minnegasco (18%); UtiliCorp United Inc., now Aquila, Inc. (12%); Northern States Power Company--Minnesota (10%); and MidAmerican Energy (10%).

As noted above, the Field Area of Northern Natural Gas' system provides access to natural gas supply from key production areas such as the Hugoton, Permian and Anadarko Basins. In each of these areas, Northern Natural Gas has numerous interconnecting receipt and delivery points, with volumes received in the Field Area consisting of both directly connected supply and volumes from interconnections with other pipeline systems. In addition, Northern Natural Gas has the ability to aggregate processable natural gas for deliveries to various gas processing facilities.

In the Field Area, customers holding transportation capacity consist of LDCs, marketers, producers, and end-users. The majority of Northern Natural Gas' Field Area firm transportation is provided to Northern Natural Gas' Market Area firm customers under long-term firm transportation contracts with such volumes supplemented by volumes transported on an interruptible basis or pursuant to short-term firm contracts. In 2001, approximately 20% of Northern Natural Gas' revenues were generated from Field Area customer transportation contracts.

Northern Natural Gas' system is characterized by significant seasonal swings in demand, which provide opportunities to deliver high value-added services. Because of its location and multiple interconnections with other interstate and intrastate pipelines, Northern Natural Gas is able to access natural gas both from traditional production areas, such as the Hugoton, Permian and Anadarko Basins, as well as growing supply areas such as the Rocky Mountains through Trailblazer Pipeline Company, Pony Express Pipeline and Colorado Interstate Gas Company, and from Canadian production areas through Northern Border Pipeline Company, Great Lakes Gas Transmission Limited Partnership and Viking Gas Transmission Company. As a result of Northern Natural Gas' geographic location in the middle of the United States and its many interconnections with other pipelines, Northern Natural Gas augments its steady end-user and LDC revenues by taking advantage of opportunities to provide intermediate transportation through pipeline interconnections for customers in other markets including Chicago, other parts of the Midwest, Texas and California.

Northern Natural Gas' storage services are provided through the operation of three underground storage fields (one in Iowa and two in Kansas) and two LNG storage peaking units. The three underground natural gas storage facilities and Northern Natural Gas' two LNG storage peaking units have a total storage capacity of approximately 59 Bcf and over 1.3 Bcf/day of peak day deliverability. These storage facilities provide Northern Natural Gas with operational flexibility for daily balancing of its system and providing services to customers for meeting their year-round loadswing requirements. In 2001, approximately 11% of Northern Natural Gas' revenues were generated from storage services.

COMPETITION

Pipelines compete on the basis of cost, flexibility, reliability of service and overall customer service. Historically, Northern Natural Gas has been able to provide competitive cost service because of its access to a variety of low cost supply basins, its cost control measures and its relatively high load factor through-put, which lowers the cost per unit of transportation. Although Northern Natural Gas has

63

experienced pipeline system bypass affecting a small percentage of its market, to date Northern Natural Gas has been able to more than offset any load lost to bypass in the Market Area through expansion projects such as the Peak Day 2000 project (described below).

Major competitors in the Market Area include ANR Pipeline Company and Natural Gas Pipeline Company of America. Other competitors include Northern Border Pipeline Company, Great Lakes Gas Transmission Limited Partnership and Viking Gas Transmission Company. In the Field Area, Northern Natural Gas competes with a large number of other competitors. Particularly in the Field Area, a significant amount of Northern Natural Gas' capacity is used on an interruptible or short-term basis. In summer months, Northern Natural Gas's Market Area customers often release significant amounts of their unused firm capacity to other shippers, which competes with Northern Natural Gas' short-term or interruptible services.

Natural gas competes with other forms of energy, including electricity, coal and fuel oil, primarily on the basis of price. The price of natural gas is influenced by legislation and governmental regulations, the weather, the futures market, production costs, and other factors beyond the control of Northern Natural Gas. Industrial end-users often have the ability to choose from alternative fuel sources in addition to natural gas, such as fuel oil and coal. Northern Natural Gas attempts to maintain its competitive position through discounting transportation to keep delivered natural gas prices in line with prices for alternative fuels and by using flexible short-term and interruptible transportation services that are contracted for on an as needed basis.

Northern Natural Gas believes that current and anticipated changes in its competitive environment have created opportunities to serve existing customers more efficiently and to meet certain growing supply needs. While LDCs provide peak day delivery growth driven by population growth and alternative fuel replacement, new off-peak demand growth is being driven primarily by power and ethanol plant expansion. Off-peak demand growth is important to Northern Natural Gas as this demand can generally be satisfied with little or no requirement for the construction of new facilities. Approximately 3,000 MW of natural gas-fired electric power plants in development have been announced in close proximity to Northern Natural Gas' system. Northern Natural Gas has been successful in competing for a significant amount of the increased demand related to the construction of new power and ethanol plants. Over the last five years, Northern Natural Gas has contracted approximately 528 mmcf/day of volume on its system from such new facilities, of which approximately 346 mmcf/day is currently in service and approximately 182 mmcf/day is scheduled to begin service between 2002 and 2005.

PIPELINE EXPANSIONS

Northern Natural Gas expects to continue evaluating potential additional pipeline expansions on an opportunistic basis. Northern Natural Gas recently completed the final year of its $110 million Peak Day 2000 Project. The Peak Day 2000 Project was designed to serve incremental load over a five-year period beginning in 1997. The Peak Day 2000 Project consists of pipeline expansion that added approximately 267 mmcf/day of capacity to serve a portion of the 528 mmcf/day of volume Northern Natural Gas has added to its system in the Market Area. Northern Natural Gas is currently negotiating precedent agreements with respect to an approximately $11 million Market Area expansion project, which we refer to as Project Max. Project Max is projected to provide Northern Natural Gas with an incremental 135 mmcf/day of capacity, primarily beginning service in 2003, including service to the MidAmerican Energy Greater Des Moines Energy Center that is currently under construction. Northern Natural Gas has a firm transportation service agreement with MidAmerican Energy to provide 96 mmcf/day of capacity to transport volumes to this plant. The plant is capable of taking up to 180 mmcf/day, all of which can be transported on Northern Natural Gas.

OVERVIEW OF REGULATION AND CONTRACTS

The FERC regulates Northern Natural Gas under the Natural Gas Act, the Natural Gas Policy Act of 1978 and other applicable statutes and regulations. The Natural Gas Act grants the FERC authority over the construction and operation of pipelines and related facilities utilized in the transportation,

64

storage and sale of natural gas in interstate commerce, including the extension, enlargement or abandonment of such facilities. The FERC also has authority to regulate rates for natural gas in interstate commerce. Northern Natural Gas holds several Certificates of Public Convenience and Necessity issued by the FERC authorizing Northern Natural Gas to construct, operate and maintain its pipeline and related facilities and services and to transport and store natural gas in interstate commerce.

Northern Natural Gas' rates and terms and conditions of service are regulated by the FERC. FERC regulations and Northern Natural Gas' tariff allow Northern Natural Gas to charge up to maximum approved rates for particular services as set forth in its tariff. Northern Natural Gas' rates are designed to provide it with the ability to recover prudently incurred operations and maintenance costs, taxes, interest, depreciation and amortization and a regulated return on equity. Natural gas companies may not grant any undue preference to any person, or maintain any unreasonable difference in their rates or other terms of service.

On August 1, 2002, the FERC issued an Order to Respond to Northern Natural Gas related to Northern Natural Gas' existing $450 million revolving credit facility and to cash management record keeping by Northern Natural Gas. Pursuant to a Stipulation and Consent Agreement dated August 8, 2002, Northern Natural Gas agreed to comply with the FERC's cash management practices and to not include the costs associated with its existing $450 million revolving credit facility in any future rate proceeding.

See "Regulation--Northern Natural Gas and Kern River."

TRANSITION SERVICES FROM DYNEGY

When Dynegy Inc. assumed ownership of Northern Natural Gas from Enron Corp. on February 1, 2002, Enron Operations Services Corp., or EOS, agreed to temporarily continue to provide certain services which it had previously provided to operate Northern Natural Gas through a transition services agreement. These services initially included physical operations, gas logistics, engineering, financial, accounting and other corporate services required to maintain and operate the system. Certain of these services, including the physical operation of the pipeline, were provided through June 30, 2002. Through January 31, 2003, EOS, pursuant to an assignment of the transition services agreement from Dynegy to us, is continuing to provide services necessary to operate the pipeline, including gas logistics, which involves gas nominations, gas scheduling and gas control and other required services, including information technology services. Additionally, on July 1, 2002, Dynegy assumed responsibility for the operations, engineering and corporate functions of Northern Natural Gas. In connection with our purchase of Northern Natural Gas from Dynegy on August 16, 2002, Dynegy has agreed to continue to provide limited support services to Northern Natural Gas pursuant to a new transition services agreement for a period ending January 31, 2003.

KERN RIVER GAS TRANSMISSION COMPANY

EXISTING FACILITIES AND BUSINESS

Kern River's principal asset is a 926-mile interstate natural gas transmission pipeline system, with an original approximate capacity of 700 mmcf/day, extending from supply areas in the Rocky Mountains to consuming markets in Utah, Nevada and California. Following the completion of several recent expansion projects, including the 2002 expansion project and the California Action Project, the design capacity of the pipeline is currently 845.5 mmcf/day. Construction of the original pipeline began on January 2, 1991 and was completed in early 1992. Kern River's pipeline is comprised of two distinguishable sections: the mainline and the common facilities. The 707-mile mainline section extends from the pipeline's point of origination in Opal, Wyoming through the Central Rocky Mountains area into Daggett, California and is owned entirely by Kern River. The common facilities consist of the 219-mile section of pipeline that extends from Daggett to Bakersfield, California. The common facilities are jointly owned by Kern River (currently approximately 67.9%) and Mojave Pipeline Company (currently approximately 32.1%), as tenants-in-common. Kern River's ownership percentage in the common facilities will increase or decrease pursuant to subsequently completed expansions by the respective joint owners.

65

COMPETITION

Generally, Kern River competes on a similar basis as other pipelines as is discussed above under the heading "Business--Northern Natural Gas Company." Pipelines compete on the basis of cost, flexibility, reliability of service and overall customer service. More specifically, Kern River competes with various interstate pipelines and its shippers in serving the southern California, Las Vegas and Salt Lake City market areas, in order to market any unsubscribed capacity and expansion capacity. Kern River provides customers with supply diversity through pipeline interconnects with Northwest pipeline, the Colorado Interstate Gas pipeline, the Overland Trail pipeline, and Questar pipeline. These interconnects allow Kern River to access natural gas reserves in Colorado, northwestern New Mexico, Wyoming, Utah and the Western Canadian Sedimentary Basin.

Approximately 100% of Kern River's original pipeline capacity is contractually committed with 14 extended term rate shippers until September 30, 2011. Beyond that, approximately 84% of the original pipeline capacity is contractually committed until September 30, 2016. Nearly 100% of the additional permanent capacity constructed in connection with the 2002 expansion and to be constructed for the 2003 Expansion Project is contractually committed under 10- and 15-year agreements.

Even though Kern River does not market natural gas supply, in each market area the purchaser evaluates the total cost of natural gas supply, including transportation rates, from each alternative supplier/transporter. Based on published rates and fuel percentages, we believe Kern River currently has the lowest transportation costs from well-head to burner tip of any interstate pipeline serving our direct markets in southern California, with gas transportation costs of approximately $0.39-0.44/MMBtu compared to approximately $0.77-$1.10/MMBtu on competing pipelines. There can be no assurance that our competitors do not or will not charge rates which are discounted to these published rates, particularly on a short-term basis. The 2003 Expansion Project shippers' initial tariff rates in the original FERC filing were $0.57-$0.70/MMBtu. These rates are expected to be reduced in a FERC compliance filing Kern River is required to make 60 days prior to placing the 2003 Expansion Project in service.

Kern River is the only interstate pipeline that presently delivers natural gas directly from a gas supply basin into the intrastate California market, which enables its customers to avoid paying a "rate stack" (i.e., additional transportation costs attributable to the movement from an interstate system to an intrastate system within California). We believe that Kern River's rate structure and access to downstream pipelines/storage facilities and to low-cost Rocky Mountain gas reserves increases its competitiveness and attractiveness to end-users. Kern River believes it is advantaged relative to other competing interstate pipelines because its relatively new pipeline can be expanded at lower costs than those that apply to other systems. Its levelized rate structures under expansion rates and settlement rates also provide Kern River's customers with future rate certainty.

OVERVIEW OF REGULATION AND CONTRACTS

The FERC regulates Kern River under the Natural Gas Act, the Natural Gas Policy Act of 1978 and other applicable FERC regulations. The Natural Gas Act grants the FERC authority over the construction and operation of pipelines and related facilities utilized in the transportation and sale of natural gas in interstate commerce, including the extension, enlargement, or abandonment of such facilities, as well as the transportation and wholesale sales of natural gas. The FERC also has authority to regulate rates for natural gas in interstate commerce. Kern River holds several Certificates of Public Convenience and Necessity issued by the FERC authorizing Kern River to construct, operate and maintain its pipeline and related facilities and to transport natural gas in interstate commerce.

Kern River's rates, charges and terms and conditions of service are regulated by the FERC. FERC regulations and Kern River's tariff allow Kern River to charge up to maximum approved rates for particular services as set forth in its tariff. Kern River's rates are designed to provide it with the ability to recover prudently incurred operations and maintenance costs, taxes, interest, depreciation and amortization and a regulated return on equity. Natural gas companies may not grant any undue preference to any person, or maintain any unreasonable difference in their rates or other terms of service.

66

Kern River's rates are set using a "levelized cost-of-service" methodology so that the rate is constant over the contract period. This is achieved by using a FERC-approved depreciation schedule in which depreciation increases as interest expenses decrease.

When Kern River commenced service in 1992, shippers signed 15-year long-term firm transportation contracts that were to expire in 2007. Under terms of a 1995 rate settlement, Kern River agreed that new rates would be filed by May 1, 1999. Instead of filing a rate case, Kern River negotiated a "pre-settlement" of the rate case with its shippers. This was approved by the FERC pursuant to a 1999 rate settlement in Docket No. RP99-274, which included an agreement for a moratorium on rate cases until May 1, 2002 under which Kern River may be required to file a rate case by May 1, 2004. In order to reduce transportation rates further and extend contract terms beyond 2007, Kern River initiated an open season in October 1998 to measure interest in lower, extended term rates for extended term contracts. Shippers were offered the choice of new 10- or 15-year contracts (4-9 year extensions of their existing contracts) with both options starting on October 1, 2001 and expiring on either September 30, 2011 or September 30, 2016. On February 8, 2001 the FERC approved implementation of the extended term rates. All existing shippers have signed up under the extended term rates program.

See "Regulation--Northern Natural Gas and Kern River."

KERN RIVER'S 2003 EXPANSION PROJECT

The 2003 Expansion Project includes the primary 2003 Expansion Project and the High Desert Lateral. Kern River filed for FERC approval of the primary 2003 Expansion Project on August 1, 2001 and the High Desert Lateral on July 18, 2001.

Primary 2003 Expansion Project. Construction commenced on August 6, 2002, and the primary 2003 Expansion Project is expected to be completed and operational by May 1, 2003 at a total cost of approximately $1.2 billion. The primary 2003 Expansion Project is a new parallel 717-mile loop pipeline that will begin in Lincoln County, Wyoming and terminate in Kern County, California. The project is designed to more than double the amount of natural gas transported on the Kern River system. The pipeline will include 36- and 42-inch diameter pipe, most of which will be laid in the existing Kern River right-of-way at a 25-foot offset from the existing pipeline, and new above ground facilities. Three segments along the right-of-way, approximately 205 miles in Utah, Nevada and California, will not require additional pipeline but will instead be areas where the gas will be compressed and transported through the existing pipeline. The existing pipeline rights-of-way, compressor facilities and receipt/delivery facilities will all be utilized by the 2003 Expansion Project, streamlining the permitting, acquisition of rights-of-way and ultimately the construction and operations of the 2003 Expansion Project.

The primary 2003 Expansion Project includes the construction of three new compressor stations and the installation of additional compression and other modifications at six existing facilities. When completed, the Kern River system will have a summer day design capacity of approximately 1.73 Bcf/day, an increase of approximately 900 mmcf/day.

Kern River has 18 long-term firm transportation service agreements with 17 shippers for 100% of the primary 2003 Expansion Project's capacity. The term for all these service agreements is either 10 or 15 years from the date on which transportation services on the 2003 Expansion Project commence.

In addition to the FERC certificate process discussed above, Kern River requires several federal and state land use, air, water and other environmental permits in order to construct and ultimately operate the 2003 Expansion Project. All required permits have been applied for and have been obtained.

High Desert Lateral. High Desert Power Project, LLC, or High Desert LLC, has commenced construction of a natural gas-fired 750 MW power plant owned by a subsidiary of Constellation Energy Group in Victorville, California. High Desert LLC has advised us that the plant is scheduled to start commercial operation by July 1, 2003.

The High Desert Lateral is a 32-mile lateral and associated meter stations designed to transport up to 282 mmcf/day of natural gas to the High Desert power plant for High Desert LLC's affiliate, Victorville Gas, LLC, from interconnects with the common facilities and PG&E Corporation near Kramer Junction.

67

Victorville Gas, LLC will be seeking to acquire gas supply and/or upstream transportation capacity from shippers on the common facilities. Kern River began construction on the High Desert Lateral in May 2002 and placed the facilities in service on August 31, 2002.

2003 Expansion Project Financing. The 2003 Expansion Project will be financed with 70% debt and 30% equity, consistent with Kern River's existing capital structure, the application for FERC approval of the 2003 Expansion Project and the limitations contained in the indenture for Kern River's existing secured senior notes. On June 21, 2002, Kern River entered into an $875 million credit facility to fund a portion of the costs of the 2003 Expansion Project and we issued a completion guarantee in favor of the lenders under that credit facility. For a more complete description of the Kern River credit facility and our completion guarantee, see "Management's Discussion and Analysis of Financial Condition and Results of Operations--Construction--Kern River's 2003 Expansion Project Financing."

CE ELECTRIC UK

The business of CE Electric UK consists primarily of the distribution of electricity in the United Kingdom by Northern Electric and Yorkshire Electricity.

In February 1997, CE Electric UK Ltd., an indirect wholly owned subsidiary of CE Electric UK, acquired Northern Electric. Northern Electric was one of the twelve original United Kingdom regional electric companies which came into existence in 1990 as a result of the restructuring and subsequent privatization of the electricity industry that occurred in the United Kingdom. On September 21, 2001, CE Electric UK Ltd. acquired 94.75% of Yorkshire Electricity from Innogy Holdings plc, or Innogy, and simultaneously sold Northern's electricity and gas supply and metering businesses to Innogy. We sometimes refer to these transactions as the Northern Electric/Yorkshire Electricity swap. In August 2002, CE Electric UK acquired the remaining 5.25% of Yorkshire Electricity that it did not already own from Xcel Energy International, an affiliate of Xcel Energy Inc.

With the acquisition of Yorkshire Electricity and the disposal of the electricity and gas supply and metering businesses of Northern Electric and certain other recent or pending strategic disposals, CE Electric UK is positioned to continue to bring together the skills and resources of two neighboring distribution businesses to create one of the largest distribution companies in the United Kingdom, serving more than 3.6 million customers in an area of approximately 10,000 square miles. CE Electric UK has also implemented a number of initiatives which have produced savings in ongoing operating and capital costs at its businesses.

BUSINESS OF CE ELECTRIC UK

Descriptions of the functional business units of each of Northern Electric's and Yorkshire Electricity's distribution businesses are set forth below. For a summary description of the deregulated energy market in the United Kingdom, see "Regulation--CE Electric UK."

ELECTRICITY DISTRIBUTION

Northern Electric's and Yorkshire Electricity's operations consist primarily of the distribution of electricity and other auxiliary businesses in the United Kingdom. Northern Electric's and Yorkshire Electricity's distribution licensee companies, Northern Electric Distribution Limited, or NED, and Yorkshire Electricity Distribution plc, or YED, receive electricity from the national grid transmission system and distribute it to their customers' premises using their network of transformers, switchgear and cables. Substantially all of the customers in NED's and YED's distribution service areas are connected to the NED and YED networks and electricity can only be delivered through their distribution system, thus providing NED and YED with distribution volume that is relatively stable from year to year. NED and YED charge fees for the use of the distribution system to the suppliers of electricity. The suppliers, which purchase electricity from generators and sell the electricity to end-user customers, use NED's and YED's distribution networks pursuant to an industry standard "Uses of System Agreement" which NED and YED separately entered into with the various suppliers of electricity in their respective distribution areas.

68

The fees that may be charged by NED and YED for use of their distribution systems are controlled by a prescribed formula that limits increases (and may require decreases) based upon the rate of inflation in the United Kingdom and other regulatory action. For a more detailed description of this pricing formula, see "Regulation--CE Electric UK."

At September 30, 2002, NED's and YED's electricity distribution network (excluding service connections to consumers) on a combined basis included approximately 31,000 kilometers of overhead lines and approximately 65,000 kilometers of underground cables. In addition to the circuits referred to above, at September 30, 2002, NED's and YED's distribution facilities also included approximately 56,600 transformers and approximately 58,000 substations. Substantially all substations are owned in freehold, and most of the balance are held on leases which will not expire within 10 years.

UTILITY SERVICES

Integrated Utility Services Limited, or IUS, a subsidiary of Northern Electric, is an engineering contracting company whose main business is providing electrical connection services on behalf of NED's and YED's distribution businesses and providing electrical infrastructure contracting services to third parties. The acquisition of Yorkshire Electricity by CE Electric UK Ltd. in 2001 has given IUS the opportunity to integrate Yorkshire Electricity's engineering contracting activities into IUS.

GENERATION

Northern Electric Generation Limited, or Northern Generation, a CE Electric UK subsidiary, presently maintains ownership interests in TPL.

Teesside Power Limited. TPL owns and operates a 1,875 net MW combined cycle gas-fired power plant at Wilton in northeast England. Northern Generation owns a 15.4% interest in TPL, but does not operate the plant. The project was initiated in the early 1990s by Enron and at the time of the Enron bankruptcy filing in December 2001, Enron, through its subsidiaries, owned a 42.5% interest in the plant, operated the plant, and contracted to purchase 668 MW of capacity from the plant. In May 2002, TPL executed a restructuring and stabilization agreement with its lenders. It is anticipated that there will be no further dividends arising from this investment and, as a result, Northern Generation wrote off its equity investment in TPL as of December 31, 2001.

Viking. In October 2002, Northern Generation sold its 50% interest in a 50MW gas fired mid-merit power plant known as Viking, located at Seal Sands in northeast England, to a subsidiary of Rolls-Royce plc.

RETAIL DISPOSAL

In August 2002, Northern Electric disposed of its non-core business of selling electrical and gas appliances which had been conducted through Northern Electric Retail Limited, a subsidiary of CE Electric UK.

GAS EXPLORATION AND PRODUCTION

CE Gas Holdings is a gas exploration and production company which is focused on developing integrated upstream gas projects. Its upstream gas business consists of the exploration, development and production, including transportation and storage, of gas for delivery to a point of sale into either a gas supply market or a power generation facility.

In May 2002, CE Gas Holdings completed the sale of most of its United Kingdom natural gas assets to Gaz de France for approximately $200 million ( (pounds sterling)137.0 million). As part of the sale, CE Gas Holdings disposed of all of its interest in the natural gas-producing fields of Anglia, Johnston, Schooner and Windermere, each of which is located in the southern basin of the United Kingdom North Sea. The sale also included all of CE Gas Holdings' rights in four gas fields in development/construction and three exploration blocks owned by CE Gas Holdings. CE Gas Holdings retained its 5% working interest in the Victor Field and its 25% interest in the ETS gas pipeline. During 2001, the Victor Field produced on average 3.5 mmcf/day of gas, and CE Gas Holdings' share of the estimated remaining gas reserves in the Victor Field is 7 Bcf.

69

In addition to retaining its interest in the Victor Field and the ETS pipeline, CE Gas Holdings retained certain development interests in Poland (Polish Trough) and Australia (Perth, Bass and Otway Basins). CE Gas Holdings' interest in the retained fields is estimated to equal approximately 150 Bcf of gas.

(1) 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 current allocation of partnership distributions.

(2) Southern California Edison Company; San Diego Gas & Electric Company; Utah Power & Light Company; New York State Electric & Gas Corporation; TXU Generation Company LP; Zinc Recovery Project; El Paso Corporation; and MidAmerican Energy.

(3) Each contract governing power purchases by the Zinc Recovery Project will expire 33 years from the date of the initial power delivery under such contract. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Construction--Zinc Recovery Project" and "Business--CalEnergy Generation--Domestic--Zinc Recovery Project."

(4) Our subsidiary owns an approximately 70% indirect interest in this project which supplies geothermal steam to a power plant owned by UP&L. We obtained a cash prepayment under a pre-sale agreement with UP&L whereby UP&L paid in advance for the steam produced by this steam field.

Cordova Project. Cordova Energy owns a 537 MW gas-fired power plant in the Quad Cities, Illinois area which we refer to as the Cordova Project. CalEnergy Generation Operating Company, our indirect wholly owned subsidiary, operates the Cordova Project. The Cordova Project commenced commercial operations in June 2001. Cordova Energy entered into a power purchase agreement with a unit of El Paso, under which El Paso will purchase all of the capacity and energy from the project until December 31, 2019. Cordova Energy has exercised an option to recall from El Paso 50% of the output through May 14, 2004, reducing El Paso's purchase obligation to 50% of the output during such period. The recalled output

70

is being sold to MidAmerican Energy. We are aware there have been public announcements that El Paso's financial condition has deteriorated as a result of, among other things, reduced liquidity. We will continue to monitor the situation.

We have a 50% ownership interest in CE Gen, which has interests in ten geothermal plants in the Imperial Valley in California (commonly referred to as the Salton Sea I, Salton Sea II, Salton Sea III, Salton Sea IV, Salton Sea V, Vulcan, Elmore, Leathers, Del Ranch and CE Turbo projects), and three natural gas-fired cogeneration plants (Saranac, Power Resources and Yuma). A subsidiary of El Paso owns the other 50% ownership interest in CE Gen. An indirect wholly owned subsidiary of CE Gen operates each of the ten Imperial Valley geothermal plants and each of the three natural gas-fired cogeneration plants. Each plant possesses an operating margin that allows for production in excess of the facility net MW amount listed in the table above. Utilization of this operating margin is based upon a variety of factors and can be expected to vary between calendar quarters, under normal operating conditions.

Imperial Valley Projects. Six of the Imperial Valley geothermal plants sell electricity to Southern California Edison Company, or Edison, under 30-year Standard Offer No. 4 Agreements, which we refer to as the SO4 Agreements. Under the SO4 Agreements, Edison is obligated to pay capacity payments, capacity bonus payments and energy payments. The price for contract capacity payments is fixed for the life of such SO4 Agreement. The energy payments are based on the cost Edison avoids by purchasing energy from the projects instead of obtaining the energy from other sources. This cost is referred to as the Avoided Cost of Energy.

In June and November 2001, six of these projects entered into agreements that provide for amended energy payments under the SO4 Agreements. The amendments provide for fixed energy payments of 5.37 cents per kWh commencing May 1, 2002 for a five year period in lieu of Edison's Avoided Cost of Energy. Following the five year period, the energy payments revert to Edison's Avoided Cost of Energy.

Two of the Imperial Valley projects have negotiated contracts with Edison. The Salton Sea I contract provides for a capacity payment and energy payment for the life of the contract. Both payments are based upon an initial value that is subject to quarterly adjustment by reference to various inflation-related indices. The Salton Sea IV contract also provides for fixed price capacity payments for the life of the contract and fixed energy prices, which are subject, in part, to quarterly adjustment by reference to various inflation-related indices, through June 20, 2017 (and at Edison's Avoided Cost of Energy thereafter), and, in part, to Edison's Avoided Cost of Energy.

The Salton Sea V and Turbo projects began operations in 2000 and, when the Zinc Recovery Project achieves 100% production, the Salton Sea V Project and the Turbo Project would expect to sell approximately 20 MW to the Zinc Recovery Project at a price based on market transactions. The remainder is being sold through other market transactions.

Saranac Project. The Saranac Project is a 240 net MW natural gas-fired cogeneration facility located in Plattsburgh, New York. The Saranac Project has entered into a 15-year power purchase agreement with New York State Electric & Gas Company expiring in 2009. The Saranac Project is a qualifying facility, or QF, and has entered into 15-year steam purchase agreements with Georgia-Pacific Corporation and Pactiv Corporation. The Saranac Project has a 15-year natural gas supply agreement with Shell Canada Limited, to supply 100% of the Saranac Project's fuel requirements. Each of the Saranac power purchase agreement, the Saranac steam purchase agreements and the Saranac gas supply agreement contains rates that are fixed for their respective contract terms. Revenues escalate at a higher rate than fuel costs. The Saranac partnership is indirectly owned by subsidiaries of CE Gen, ArcLight Capital Partners LLC and General Electric Capital Corporation.

Power Resources Project. The Power Resources Project is a 200 net MW natural gas-fired cogeneration project located near Big Spring, Texas, which has a 15-year power purchase agreement with TXU Generation Company LP, formerly known as Texas Utilities Electric Company expiring in 2003. The Power Resources Project is a QF and has a steam purchase agreement with Alon USA, L.P.

71

Yuma Project. The Yuma Project is a 50 net MW natural gas-fired cogeneration project in Yuma, Arizona providing 50 MW of electricity to San Diego Gas & Electric Company under an existing 30-year power purchase agreement which expires in 2024. The Yuma project is a QF and has executed steam sales contracts with an adjacent industrial entity to act as its thermal host.

Roosevelt Hot Springs. One of our subsidiaries operates and owns an approximately 70% indirect interest in a geothermal steam field which supplies geothermal steam to a 23 net MW power plant owned by Utah Power & Light Company, or UP&L, located on the Roosevelt Hot Springs property under a 30-year steam sales contract expiring in 2020. We obtained a cash prepayment under a pre-sale agreement with UP&L whereby UP&L paid in advance for the steam produced by the steam field. We guarantee the performance of this subsidiary. We must make certain penalty payments to UP&L if the steam produced does not meet certain quantity and quality requirements.

Zinc Recovery Project. CalEnergy Minerals LLC is constructing the Zinc Recovery Project which will recover zinc from the geothermal brine. Facilities are being installed near the Imperial Valley project's sites to extract a zinc chloride solution from the geothermal brine through an ion exchange process. This solution will be transported to a central processing plant where zinc ingots will be produced through solvent extraction, electrowinning and casting processes. The Zinc Recovery Project is operated by an indirect wholly owned subsidiary of CE Gen, is designed to have a capacity of approximately 30,000 metric tons per year, and has commenced initial commercial operations in 2002. The Zinc Recovery Project is expected to be at 100% production in mid- 2003.

DEVELOPMENT PROJECTS

Fox Energy. Our subsidiary, Fox, is developing a 635 net MW gas fired power generating facility in Kaukanna, Outagamie County, Wisconsin. A subsidiary of TransAlta Corporation has agreed to participate in the development of this project at a level of 50% and has an option to own 50% of the project. A Certificate of Public Convenience and Necessity was issued by the Public Service Commission of Wisconsin on November 8, 2002. An air permit for construction and initial operations was issued by the Wisconsin Department of Natural Resources on November 4, 2000 and such application was deemed complete on April 25, 2002. A final environmental impact statement was issued by the Wisconsin Department of Natural Resources on August 19, 2002. Electrical and natural gas interconnection agreements and a water supply agreement have also been executed for this project.

Salton Sea VI. Our subsidiary, Obsidian, is developing a 185 net MW geothermal facility in Imperial Valley, California. Substantially all the output of the facility will be sold to the Imperial Irrigation District pursuant to a power purchase agreement. An affiliate of El Paso has elected to participate in the ownership and development of this project at a level of 50%. On July 29, 2002, Obsidian filed an application for certification seeking approval from the California Energy Commission to construct and operate the facility.

(1) Actual MW may vary depending on operating and reservoir conditions and plant design. Facility Net Capacity (in MW) represents the contract capacity for the facility. Net MW owned indicates current legal ownership, but, in some cases, does not reflect the current allocation of distributions.

(2) PNOC--Energy Development Corporation, or PNOC-EDC, Republic of the Philippines, or ROP, and NIA (NIA also purchases water from this facility). The government of the Philippines undertaking supports PNOC-EDC's and NIA's respective obligations.

(3) Subject to repurchase rights of up to 15% of the project by an initial minority shareholder and a dispute with the other initial minority shareholder regarding an additional 15% of the project. Also see "Legal Proceedings--Casecnan Shareholder Litigation" and note 20 to our consolidated financial statements for the year ended December 31, 2001 for a discussion of legal proceedings regarding this ownership interest.

We indirectly own the Upper Mahiao, Malitbog and Mahanagdong projects, which are geothermal power plants located on the island of Leyte in the Philippines, and the Casecnan Project, a combined irrigation and hydroelectric power generation project, which is located in the central part of Island of Luzon in the Philippines. One of our indirect wholly owned subsidiaries operates each of these projects. Each plant possesses an operating margin that allows for production in excess of the amount listed above. Utilization of this operating margin is based upon a variety of factors and can be expected to vary between calendar quarters, under normal operating conditions.

Mahanagdong. The Mahanagdong Project is a 165 net MW geothermal power project owned and operated by CE Luzon Geothermal Power Company, Inc., or CE Luzon, a Philippine corporation of which we indirectly own 100% of the common stock. Another industrial company owns an approximate 10% preferred equity interest in the Mahanagdong Project. The Mahanagdong Project has been in commercial operation since July 25, 1997. The Mahanagdong Project sells 100% of its capacity on a similar basis as described above for the Upper Mahiao Project to PNOC-EDC, which in turn sells the power to the NPC for distribution on the island of Luzon.

The terms of the Mahanagdong energy conversion agreement are substantially similar to those of the Upper Mahiao agreement. The Mahanagdong agreement provides for a ten-year cooperation period. At the end of the cooperation period, the facility will be transferred to PNOC-EDC at no cost. All of PNOC-EDC's obligations under the Mahanagdong agreement are supported by the Republic of the Philippines through a performance undertaking. The capacity fees are approximately 97% of total revenues at the design capacity levels and the energy fees are approximately 3% of such total revenues. PNOC-EDC's payment requirements, and its other obligations under the Mahanagdong agreement, are supported by the Republic of the Philippines through a performance undertaking.

Malitbog. The Malitbog Project is a 216 net MW geothermal project owned and operated by Visayas Geothermal Power Company, or VGPC, a Philippine general partnership that is wholly owned, indirectly, by us. The three units of the Malitbog facility were put into commercial operation on July 25, 1996 (for Unit
I) and July 25, 1997 (for Units II and III). VGPC sells 100% of its capacity on substantially the same basis as described above for the Upper Mahiao Project to PNOC-EDC, which sells the power to the NPC for distribution on the islands of Cebu and Luzon.

The electrical energy produced by the facility is sold to PNOC-EDC on a take-or-pay basis. These capacity payments equal approximately 100% of total revenues. A substantial majority of the capacity payments are required to be made by PNOC-EDC in dollars. The portion of capacity payments payable to PNOC-EDC in pesos is expected to vary over the term of the Malitbog energy conversion agreement from 10% of VGPC's revenues in the early years of the 10-year cooperation period to 23% of VGPC's revenues at the end of the cooperation period. Payments made in pesos will generally be made to a peso-dominated account and will be used to pay peso-denominated operation and maintenance expenses with respect to the Malitbog Project and Philippine withholding taxes, if any, on the Malitbog Project's debt service. The government of the Philippines has entered into a performance undertaking, which provides that all of PNOC-EDC's obligations pursuant to the Malitbog energy conversion agreement carry the full faith and credit of, and are affirmed and guaranteed by, the Republic of the Philippines.

73

The Malitbog energy conversion agreement cooperation period expires ten years after the date of commencement of commercial operation of Unit III. At the end of this cooperation period, the facility will be transferred to PNOC-EDC at no cost, on an "as is" basis. See "Legal Proceedings" for a description of legal proceedings related to the Malitbog Project.

Upper Mahiao. The Upper Mahiao facility is a 119 net MW geothermal power project owned and operated by CE Cebu Geothermal Power Company, Inc., or CE Cebu, a Philippine corporation that is 100% indirectly owned by us. The Upper Mahiao facility has been in commercial operation since June 17, 1996.

Under the terms of the Upper Mahiao energy conversion agreement, CE Cebu owns and operates the Upper Mahiao Project during the ten-year cooperation period, which commenced in June 1996, after which ownership will be transferred to PNOC-Energy Development Corporation, or PNOC-EDC, at no cost.

The Upper Mahiao Project is located on land provided by PNOC-EDC at no cost. The project takes geothermal steam and fluid, also provided by PNOC-EDC at no cost, and converts its thermal energy into electrical energy which is sold to PNOC-EDC on a "take-or-pay" basis, which in turn sells the power to the NPC, for distribution on the island of Cebu. PNOC-EDC pays to CE Cebu a 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 based on the electricity actually delivered to PNOC-EDC (approximately 5% of total contract revenues). Payments under the Upper Mahiao agreement 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. PNOC-EDC's payment requirements, and its other obligations under the Upper Mahiao agreement, are supported by the Republic of the Philippines through a performance undertaking.

Casecnan. CE Casecnan, our indirectly majority owned subsidiary, operates the Casecnan Project, a combined irrigation and 150 net MW hydroelectric power generation project. The Casecnan Project consists generally of diversion structures in the Casecnan and Taan Rivers that captures and diverts excess water in the Casecnan watershed by means of concrete, in-stream diversion weirs and transfers that water through a transbasin tunnel of approximately 23 kilometers (including the intake audit from the Taan to the Casecnan River), with a diameter of approximately 6.5 meters to an existing underutilized water storage reservoir at Pantabangan. During the water transfer, the elevation differences between the two watersheds allows electrical energy to be generated at a 150 net MW rated capacity power plant, which is located in an underground powerhouse cavern at the end of the water tunnel. A tailrace discharge tunnel of approximately three kilometers delivers water from the water tunnel and the powerhouse to the Pantabangan Reservoir, providing additional water for irrigation and increasing the potential electrical generation at two downstream existing hydroelectric facilities of the NPC, the government-owned and controlled corporation that is the primary supplier of electricity in the Philippines.

CE Casecnan constructed the Casecnan Project under the terms of the project agreement between CE Casecnan and NIA. Under the project agreement, CE Casecnan developed, financed and arranged for the construction of the Casecnan Project, and will own and operate the Casecnan Project for 20 years. During this cooperation period, NIA is obligated to accept all deliveries of water and energy, and so long as the Casecnan Project is physically capable of operating and delivering in accordance with agreed levels set forth in the project agreement, NIA will pay CE Casecnan a fixed fee for the delivery of a minimum volume of water and a fixed fee for the delivery of a minimum amount of electricity. In addition, NIA will pay a fee for all electricity delivered in excess of a threshold amount up to a specified amount. NIA will sell the electricity it purchases to the NPC, although NIA's obligations to CE Casecnan under the project agreement are not dependent on the NPC's purchase of the electricity from NIA. All fees to be paid by NIA to CE Casecnan are payable in U.S. dollars. The fixed fees for the delivery of water and energy, regardless of the amount of electricity or water actually delivered, are expected to provide approximately 78% of CE Casecnan's revenues. At the end of the cooperation period, the Casecnan Project will be transferred to NIA and the NPC for no additional consideration on an "as is" basis.

74

The Republic of the Philippines has provided a performance undertaking under which NIA's obligations under the project agreement are guaranteed by the full faith and credit of the Republic of the Philippines. See "Legal Proceedings" for a description of legal proceedings related to the Casecnan Project.

NORTHERN NATURAL GAS AND KERN RIVER

At September 30, 2002, Northern Natural Gas' system was comprised of approximately 7,300 miles of mainline transmission pipes and approximately 9,300 miles of smaller diameter branch lines and laterals. Northern Natural Gas' storage services are provided through the operation of three underground storage fields, in Redfield, Iowa, and Lyons and Cunningham, Kansas. The three underground natural gas storage facilities and Northern Natural Gas' two liquefied natural gas storage peaking units have a total storage capacity of approximately 59 Bcf. Northern Natural Gas' two LNG liquefaction/vaporization facilities are located near Garner, Iowa and Wrenshall, Minnesota with storage capacity of 2 Bcf each.

At September 30, 2002, Kern River's pipeline was comprised of two distinguishable sections: the mainline and the common facilities. The 707-mile mainline section extends from the pipeline's point of origination in Opal, Wyoming through the Central Rocky Mountains area into Daggett, California and is owned entirely by Kern River. The common facilities consist of the 219-mile section of pipeline that extends from Daggett to Bakersfield, California. The common facilities are jointly owned by Kern River (currently approximately 67.9%) and Mojave Pipeline Company (currently approximately 32.1%) as tenants-in-common.

The right to construct and operate the pipelines across certain property was obtained through negotiations and through the exercise of the power of eminent domain, where necessary. Northern Natural Gas and Kern River continue to have the power of eminent domain in each of the states in which they operate their respective pipelines, but they do not have the power of eminent domain with respect to Native American tribal lands. Although the main Kern River pipeline crosses the Moapa Indian Reservation, all facilities are located within a utility corridor that is reserved to the United States Department of Interior, Bureau of Land Management.

With respect to real property, each of the pipelines falls into two basic categories: (1) parcels that are owned in fee, such as certain of the compressor stations, measurement stations and district office sites; and (2) parcels where the interest derives from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities permitting the use of such land for the construction, operation and maintenance of the pipelines.

We believe that Northern Natural Gas and Kern River each have satisfactory title to all of the real property making up their respective pipelines in all material respects.

CE ELECTRIC UK

At September 30, 2002, Northern Electric's and Yorkshire Electricity's electricity distribution networks (excluding service connection to consumers) on a combined basis included approximately 31,000 kilometers of overhead lines and approximately 65,000 kilometers of underground cables. In addition to the circuits referred to above, at September 30, 2002, Northern Electric's and Yorkshire Electricity's distribution facilities also included approximately 56,600 transformers and approximately 58,000 substations.

OTHER PROPERTIES

At September 30, 2002, our most significant physical properties, other than those owned by MidAmerican Energy, Northern Natural Gas, Kern River and CE Electric UK, are our current interests in operating power facilities and our plants under construction and related real property interests, as well as leases of office space for our residential real estate brokerage operations. See "Business" for further detail.

REGULATION

Our operating platforms are subject to a number of federal, state, local and international regulations.

MIDAMERICAN ENERGY

MidAmerican Energy is subject to comprehensive regulation by utility regulatory agencies in Iowa, Illinois and South Dakota that significantly influences the operating environment and the recoverability of costs from utility customers. Except for Illinois, that regulatory environment has to date, in general, given MidAmerican Energy an exclusive right to serve electricity customers within its service territory and, in turn, the obligation to provide electric service to those customers. In Illinois all customers are free to choose their electricity provider. MidAmerican Energy has an obligation to serve customers at regulated rates that leave MidAmerican Energy's system, but later choose to return. To date, there has been no significant loss of customers from MidAmerican Energy's existing regulated Illinois rates.

In connection with the March 1999 approval by the IUB of the MidAmerican Energy acquisition and March 2000 affirmation as part of our acquisition by a private investor group, we agreed, among other things, to use all commercially reasonable efforts to maintain an investment grade credit rating for MidAmerican Energy's utility operations and its long-term debt and to seek the approval of the IUB of a reasonable utility capital structure if MidAmerican Energy's utility operations' common equity level decreases below 42%, excluding circumstances beyond its control, or below 39%, under any circumstances. MidAmerican Energy's utility operations' common equity level at December 31, 2001 and September 30, 2002 was above these levels.

With the elimination of its energy adjustment clause in Iowa in 1997, MidAmerican Energy is financially exposed to movements in energy prices. Although MidAmerican Energy has sufficient low cost generation under typical operating conditions for its retail electric needs, a loss of adequate generation by MidAmerican Energy requiring the purchase of replacement power at a time of high market prices could subject MidAmerican Energy to losses on its energy sales.

In December 1999, the FERC issued Order No. 2000 establishing among other things minimum characteristics and functions for regional transmission organizations. Public utilities that were not a member of an independent system operator at the time of the order were required to submit a plan by which their transmission facilities would be transferred to a regional transmission organization. On September 28, 2001, MidAmerican Energy and five other electric utilities filed with the FERC a plan to create TRANSLink Transmission Company LLC and to integrate their electric transmission systems into a single, coordinated system operating as a for-profit independent transmission company in conjunction with a FERC approved regional transmission organization. On April 25, 2002, the FERC issued an order approving the transfer of control of MidAmerican Energy's and other utilities' transmission assets to TRANSLink in conjunction with TRANSLink's participation in the Midwest ISO. Additionally, state regulatory approval is required from states in which TRANSLink will be operating and those applications have not yet been filed. Once filed, MidAmerican Energy does not anticipate rulings in the state proceedings until some time in 2003. Transferring operation and control of MidAmerican Energy's transmission assets to other entities could increase costs for MidAmerican Energy; however, the actual impact of TRANSLink on MidAmerican Energy's future transmission costs is not yet known.

On July 31, 2002, the FERC issued a notice of proposed rulemaking with respect to Standard Market Design for the electric industry. The FERC has characterized the proposal as portending "sweeping changes" to the use and expansion of the interstate transmission and the wholesale bulk power systems in the United States. The proposal includes numerous proposed changes to the current regulation of transmission and generation facilities designed "to promote economic efficiency" and replace the "obsolete patchwork we have today," according to the FERC's chairman. The final rule, if adopted as currently proposed, would require all public utilities operating transmission facilities subject to the FERC jurisdiction to file revised open access transmission tariffs that would require changes to the basic services these public utilities currently provide. The proposed rule may impact the costs and/or pricing of MidAmerican Energy's electricity and transmission products. The FERC does not envision that a final rule will be fully implemented until September 30, 2004. We are still evaluating the proposed rule, and we

77

believe that the final rule could vary considerably from the initial proposal. Accordingly, we are presently unable to quantify the likely impact of the proposed rule on us.

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 us, which would result in increased compliance costs, could have a material adverse effect on our results of operations.

Under a settlement agreement approved by the IUB on December 21, 2001, MidAmerican Energy's Iowa retail rates in effect on December 31, 2000 are frozen through December 31, 2005. Additionally, this settlement agreement reinstates, with modifications, the revenue sharing provisions of a 1997 pricing plan settlement agreement, which expired on December 31, 2000. The settlement agreement further provides that an amount equal to 50% of revenues associated with Iowa retail electric returns on equity between 12% and 14%, and 83.33% of revenues associated with Iowa retail electric returns on equity above 14%, in each year will be recorded as a regulatory liability to be used to offset a portion of the cost to Iowa customers of future generating plant investment. An amount equal to the regulatory liability will be recorded as a regulatory charge in depreciation and amortization expense when the liability is accrued. Interest expense is accrued on the portion of the regulatory liability related to prior years. Beginning in 2002, the liability is being reduced as it is credited against allowance for funds used during construction or capitalized financing costs associated with generating plant additions. As of September 30, 2002, the related regulatory liability was $95.0 million. In Iowa, MidAmerican Energy does not have an energy adjustment clause, so any significant increase in fuel costs or purchased power costs could have a negative impact on MidAmerican Energy.

Under an Illinois restructuring law enacted in 1997, as amended in 2002, a sharing mechanism is in place for MidAmerican Energy's Illinois regulated retail electric operations whereby earnings above a computed level of return on common equity will be shared equally between customers and MidAmerican Energy. MidAmerican Energy's computed level of return on common equity is based on a rolling two-year average of the Monthly Treasury Long-Term Average Rate, as published by the Federal Reserve System, plus a premium of 8.5% for 2000 through 2004 and a premium of 12.5% for 2005 and 2006. The two-year average above which sharing must occur for 2001 was 14.34%. The law allows MidAmerican Energy to mitigate the sharing of earnings above the threshold return on common equity through accelerated recovery of regulatory assets.

On September 21, 2001, MidAmerican Energy filed a petition with the South Dakota Public Utilities Commission, or SDPUC, to increase its South Dakota natural gas rates. On February 20, 2002, the SDPUC approved a settlement agreement allowing increased rates of $3.1 million annually.

On October 19, 2001, MidAmerican Energy filed a petition with the Illinois Commerce Commission to increase its Illinois natural gas rates. On September 11, 2002, the Illinois Commerce Commission issued an order granting MidAmerican Energy a $2.2 million annual increase in rates.

On March 15, 2002, MidAmerican Energy made a filing with the IUB requesting an increase in rates of approximately $26.6 million for its Iowa retail natural gas customers. As part of the filing, MidAmerican Energy requested an interim rate increase of approximately $20.4 million annually. On June 12, 2002, the IUB issued an order granting MidAmerican Energy an interim increase of approximately $13.8 million annually, effective immediately and subject to refund with interest. On July 15, 2002 MidAmerican Energy and the Office of Consumer Advocate filed a proposed settlement agreement with the IUB. The settlement agreement, which was approved by the IUB on November 8, 2002, provides for an increase in rates of $17.7 million annually for MidAmerican Energy's Iowa retail natural gas customers and freezes such rates for two years after the date the IUB approves tariffs implementing the settlement agreement. MidAmerican Energy implemented the new rates effective November 25, 2002.

NORTHERN NATURAL GAS AND KERN RIVER

Northern Natural Gas and Kern River are subject to regulation by various federal and state agencies as discussed below.

78

As owners of interstate natural gas pipelines, Northern Natural Gas' and Kern River's rates, services and operations are subject to regulation by the FERC. The FERC administers, among other things, the Natural Gas Act and the Natural Gas Policy Act. Additionally, interstate pipeline companies are subject to regulation by the Department of Transportation pursuant to the Natural Gas Pipeline Safety Act, which establishes safety requirements in the design, construction, operations and maintenance of interstate natural gas transmission facilities.

The FERC has jurisdiction over, among other things, the construction and operation of pipelines and related facilities used in the transportation, storage and sale of natural gas in interstate commerce, including the extension, enlargement or abandonment of such facilities. The FERC also has jurisdiction over the rates and charges and terms and conditions of service for the transportation of natural gas in interstate commerce. Our pipeline subsidiaries also are required to file with the FERC an annual report on Form 2, which is publicly available, disclosing general corporate information and financial statements regarding our pipeline subsidiaries.

Northern Natural Gas has implemented a straight fixed variable rate design which provides that all fixed costs assignable to firm capacity customers, including a return on equity, are to be recovered through fixed monthly demand or capacity reservation charges which are not a function of throughput volumes.

Northern Natural Gas' current tariff structure provides for:

o seasonality in demand rates;

o extension of the majority of firm storage and transport contracts through May 31, 2003 and October 31, 2003, respectively;

o a rate moratorium through October 31, 2003, with limited re-openers based on the FERC's rulemaking changes; and

o the right of Northern Natural Gas to file for term-differentiated rates, if allowed.

Northern Natural Gas' tariff rates were designed to recover a cost of service that would reflect a 12.3% return on equity based upon the settlement reached in FERC Docket No. RP 98-203. Northern Natural Gas' last rate case was filed on May 1, 1998, and its next rate case may be filed no earlier than May 2003 and no later than May 2004. Northern Natural Gas' most likely next rate case filing date is May 1, 2003 with filed rates to be effective November 1, 2003.

Kern River's tariff rates were designed to recover a cost of service that would reflect a 13.25% return on equity. Kern River's rates are set using a "levelized cost-of-service" methodology so that the rate is constant over the contract period. This is achieved by using a FERC-approved depreciation schedule in which depreciation increases as interest expense decreases.

In 2000, the FERC issued new rules with respect to terms and conditions of interstate pipeline transportation service pursuant to Order No. 637. In Order No. 637, the FERC made changes to its regulatory model to enhance the effectiveness and efficiency of gas markets as they evolved since the series of FERC orders commonly referred to as Order No. 636, which were adopted beginning in the early 1990s and which provided for the restructuring of interstate pipeline sales and services. Specifically, in Order No. 637 the FERC:

o addressed alternatives to traditional pipeline pricing by permitting peak/off-peak and term differentiated rate structures;

o revised certain reporting requirements; and

o made changes in regulations related to (1) scheduling equality for released capacity, (2) capacity segmentations, and (3) pipeline imbalance services, operational flow orders and penalties.

On July 17, 2000, Northern Natural Gas made its initial compliance filing in accordance with the FERC's Order No. 637. Northern Natural Gas made a revised Order No. 637 compliance filing on March 4, 2002 and a supplemental filing on May 10, 2002. On November 21, 2002, the FERC issued an Order on Compliance with Order Nos. 637, 587-G and 587-L. In the November 21, 2002 Order, the FERC found that Northern Natural Gas generally complied with Order Nos. 637, 587-G and 587-L, subject to certain modifications, and ordered Northern Natural Gas to file compliance tariffs within 30 days.

79

On June 15, 2000, Kern River filed pro forma tariff sheets in Docket No. RP00-337 to comply with the FERC's directives in Order No. 637. In its May 30, 2002 "Order on Compliance with Order No. 637 and Second Order on Compliance with Order Nos. 587-G and 587-L," the FERC found that Kern River had generally complied with the requirements of Order Nos. 637, 587-G and 587-L, subject to the certain modifications.

On October 31, 2002, the FERC issued an order that generally accepted Kern River's tariff filings to comply with Order Nos. 637, 587-G and 587-L. In the order, the FERC directed Kern River to provide a park and loan service and to make changes addressing segmentation as well as forward and backhaul nominations.

On June 28, 2002, Kern River filed tariff sheets to comply with the FERC's order. These tariff sheets are pending action by the FERC. On September 30, 2002, the FERC issued an order on Kern River's compliance filing with Order No. 587-0. The FERC found that Kern River generally complied with the requirements of Order No. 587-0 and that Kern River should refile its title transfer tracking service.

As a result of the FERC's policies favoring competition in gas markets and the expansion of existing pipelines and construction of new pipelines, the interstate pipeline industry has begun to experience some turnback of firm capacity as existing transportation service agreements expire and are terminated. LDCs and end-use customers have more choices in the new, more competitive environment and may be able to shift load from one pipeline to another. If a pipeline experiences capacity turnback and is unable to remarket the capacity, the pipeline or its other customers may have to bear the costs associated with the capacity that is turned back. These issues will be resolved in a pipeline's general rate case proceedings.

The FERC also has authority over gas pipelines' accounting practices. The FERC recently issued a notice of proposed rulemaking regarding gas accounting issues which would limit the ability of gas pipelines to enter into cash management agreements with their parent companies. We are in the process of reviewing such proposed rule, but we do not believe the rule will have a material adverse impact on us and our pipeline subsidiaries. See "Business--Northern Natural Gas Company--Overview of Regulation and Contracts" and "Business--Kern River Gas Transmission Company--Overview of Regulation and Contracts."

Additional proposals and proceedings that might affect the interstate pipeline industry are considered from time to time by Congress, the FERC, state regulatory bodies and the courts. In some states various forms of restructuring legislation have been passed and in many states local utility regulatory agencies are overseeing the restructuring. As a result of restructuring, LDCs could unbundle their services and withdraw from all or part of their merchant function, and electric utilities could divest their generating function. This restructuring would result in the interstate pipelines having different customer profiles, including independent gas marketers and independent power generators and end-users. We cannot predict when or if any new proposals might be implemented or, if so, how Northern Natural Gas and Kern River might be affected.

OTHER UNITED STATES REGULATION

The Public Utility Regulatory Policies Act of 1978, as amended, or PURPA, and PUHCA are two of the laws (including the regulations thereunder) that affect our and certain of our subsidiaries' operations. PURPA provides to QFs certain exemptions from federal and state laws and regulations, including organizational, rate and financial regulation. PUHCA extensively regulates and restricts the activities of registered public utility holding companies and their subsidiaries. Congress is currently considering major changes to both PUHCA and PURPA in a House-Senate conference on a comprehensive energy bill (H.R. 4). The Senate version of the bill (S. 517) would repeal PUHCA and replace it with provisions giving state and federal regulators enhanced access to the books and records of all utility holding companies. The Senate bill would also prospectively repeal PURPA's mandatory purchase obligation for utilities, but this provision would not abrogate CalEnergy Generation-Domestic's existing QF contracts. Any such legislation, if adopted, could vary considerably from the terms contained in either or both of the House and Senate versions which are presently under consideration. We believe that if the current proposed legislation is passed, it would apply to new projects only and thus, although potentially

80

impacting our ability to develop new domestic projects, it would not affect our existing qualifying facilities. We cannot assure you, however, that legislation, if passed, or any other similar legislation proposed in the future, would not adversely impact our existing domestic projects.

We are currently exempt from regulation under all provisions of PUHCA, except the provisions that regulate the acquisition of securities of public utility companies, based on the intrastate exemption in Section 3(a)(1) of PUHCA. In order to maintain this exemption, we and each of our public utility subsidiaries from which we derive a material part of our income (currently only MidAmerican Energy) must be predominantly intrastate in character and organized in and carry on our and their respective utility operations substantially in our state of organization (currently Iowa). Except for MidAmerican Energy's generating plant assets, the majority of our domestic power plants and all of our foreign utility operations are not public utilities within the meaning of PUHCA as a result of their status as QFs under PURPA (with our ownership interest therein limited to 50%), exempt wholesale generators or foreign utility companies, or are otherwise exempted from the definition of "public utility" under PUHCA. Although we believe that we will continue to qualify for exemption from additional regulation under PUHCA, it is possible that as a result of the expansion of our public utility operations, loss of exempt status by one or more of our domestic power plants or foreign utilities, or amendments to PUHCA or the interpretation of PUHCA, we could become subject to additional regulation under PUHCA in the future. There can be no assurances that such regulation would not have a material adverse effect on us.

In the event we were unable to avoid the loss of QF status for one or more of our affiliate's 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, which, in the event of the loss of QF status for one or more facilities, could have a material adverse effect on us.

Regulatory requirements applicable in the future to nuclear generating facilities could adversely affect the results of operations of us and MidAmerican Energy, in particular. We are subject to certain generic risks associated with utility nuclear generation, including risks arising from the operation of nuclear facilities and the storage, handling and disposal of high-level and low-level radioactive materials; risks of a serious nuclear incident; limitations on the amounts and types of insurance commercially available in respect of losses that might arise in connection with nuclear operations; and uncertainties with respect to the technological and financial aspects of decommissioning nuclear plants at the end of their licensed lives. The Nuclear Regulatory Commission has broad authority under federal law to impose licensing and safety-related requirements for the operation of nuclear generating facilities. Revised safety requirements promulgated by the Nuclear Regulatory Commission have, in the past, necessitated substantial capital expenditures at nuclear plants, including those in which MidAmerican Energy has an ownership interest, such as the Quad Cities units, and additional such expenditures could be required in the future.

CE ELECTRIC UK

Since 1990, the electricity generation, supply and distribution industries in Great Britain have been privatized, and competition has been introduced in generation and supply. Electricity is produced by generators, transmitted through the national grid transmission system by The National Grid Company plc (or in Scotland by Scottish Power or Scottish Hydro Electric) and distributed to customers by the fourteen Distribution License Holders, which we refer to as DLHs, in their respective distribution service areas. During the fourth quarter of 1998, the market for supplying electricity began to be opened to competition through a phased-in program. This program, which proceeded by geographic areas, was completed in 1999.

Under the Utilities Act 2000, the public electricity supply license created pursuant to the Electricity Act 1989 was replaced by two separate licenses--the electricity distribution license and the electricity supply license. When the relevant provision of the Utilities Act 2000 became effective on October 1, 2001, the public electricity supply licenses formerly held by Northern Electric plc and Yorkshire Electricity Group plc were split so that separate subsidiaries held licenses for electricity distribution and electricity supply. In order to comply with the Utilities Act 2000 and to facilitate this license splitting, Northern Electric plc and Yorkshire Electricity Group plc (and each of the other holders of the former public

81

electricity supply licenses) each made a statutory transfer scheme that was approved by the Secretary of State for Trade and Industry. These schemes provided for the transfer of certain assets and liabilities to the licensed subsidiaries. This occurred on October 1, 2001, a date set by the Secretary of State for Trade and Industry. As a consequence of these schemes, the electricity distribution businesses of Northern Electric plc and Yorkshire Electricity Group plc were transferred to NED and YED, respectively. NED and YED are each holders of an electricity distribution license. The residual elements of the Electricity Supply licenses were transferred to Innogy in connection with the sale of Northern Electric's electricity and gas supply business to Innogy and the retention by Innogy of the electricity and gas supply business of Yorkshire Electricity, all as a part of the Northern Electric/Yorkshire Electricity Swap on September 21, 2001.

Each of the DLHs is required to offer terms for connection to its distribution system and for use of its distribution system to any person. In providing the use of its distribution system, a DLH must not discriminate between users, nor may its charges differ except where justified by differences in cost.

Most revenue of the DLHs is controlled by a distribution price control formula which is set out in the license of each DLH. It has been the practice of Ofgem (and its predecessor body, the Office of Electricity Regulation), to review the formula periodically and to reset it at intervals of five year duration. The formula may be varied with the consent of the DLH, or if the DLH does not consent, following a review by the U.K.'s competition authority.

The periodic review during which the formula is reset is the process by which Ofgem determines its view of the future allowed revenue of DLHs. The procedure and methodology adopted at a price control review is at the reasonable discretion of Ofgem. At the last such review, concluded in 1999 and effective April 2000, Ofgem's judgment of the future allowed revenue of licensees was based upon, among other things:

o the actual operating costs of each of the licensees;

o the operating costs which each of the licensees would incur if it were as efficient as, in Ofgem's judgment, the most efficient licensee;

o the regulatory value to be ascribed to each of the licensees' distribution network assets;

the allowance for depreciation of the distribution network assets of each of the licensees;

o the rate of return to be allowed on investment in the distribution network assets by all licensees; and

o the financial ratios of each of the licensees and the license requirement for each licensee to maintain an investment grade status.

As a result of the most recent review, the allowed revenue of Northern Electric's distribution business was reduced by 24%, in real terms, and the allowed revenue of Yorkshire Electricity's distribution business was reduced by 23%, in real terms, with effect from April 1, 2000. The range of reductions for all licensees in Great Britain was between 4% and 33%.

For the duration of the current regulatory period, the 1999 review also requires that regulated distribution revenue per unit be increased or decreased each year by RPI-Xd, where the factor "RPI" is the United Kingdom retail price index reflecting the average of the 12-month inflation rates recorded for each month in the previous July to December period and "Xd" is an adjustment factor which was established by Ofgem at the 1999 review (and continues to be 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. This formula determines the maximum average price per unit of electricity distributed (in pence per kilowatt hour) which a DLH is entitled to charge. The distribution price control formula permits DLHs to receive additional revenues due to increased distribution of units and a predetermined increase in customer numbers. Once set, the price control formula does not, during its duration, seek to constrain the profits of a DLH from year to year. It is a control on revenue that operates independently of most of the DLH's costs. During the duration of the price control, additional cost savings or costs, if any, therefore directly impact profit.

82

The distribution prices allowable under the current distribution price control formula are expected to be reviewed by Ofgem in time for a revised formula to take effect from April 1, 2005. The formula may be further reviewed at other times in the discretion of the regulator. Ofgem has recently modified the licenses of all DLHs to implement an "Information and Incentives Project" under which up to 2% of a DLH's regulated income depends upon the performance of the DLH's distribution system as measured by the number and duration of customer interruptions and upon the level of customer satisfaction monitored by Ofgem.

Under the Utilities Act 2000, GEMA is able to impose financial penalties on license holders who contravene (or have in the past contravened) any of their license duties or certain of their duties under the Electricity Act 1989 or who are failing (or have in the past failed) to achieve a satisfactory performance in relation to the individual standards of performance prescribed by GEMA. Any penalty imposed must be reasonable and may not exceed 10% of the licensee's revenue.

CALENERGY GENERATION--DOMESTIC

Each of the operating domestic power facilities owned through CE Gen meets the requirements promulgated under PURPA to be qualifying facilities, except for Cordova Energy. Qualifying facility or "QF" status under PURPA provides two primary benefits. First, regulations under PURPA exempt QFs from PUHCA, the FERC rate regulation under the Federal Power Act and the state laws concerning rates of electric utilities and financial and organization regulations of electric utilities. Second, the FERC's regulations promulgated under PURPA require that
(1) electric utilities purchase electricity generated by QFs, the construction of which commenced on or after November 9, 1978, at a price based on the purchasing utility's Avoided Cost of Energy, (2) electric utilities sell back-up, interruptible, maintenance and supplemental power to QFs on a non-discriminatory basis, and (3) electric utilities interconnect with QFs in their service territories. There can be no assurance that the QF status of such CalEnergy Generation--Domestic facilities will be maintained.

CORDOVA ENERGY

Cordova Energy is exempt from regulation under PUHCA because it is an exempt wholesale generator. PUHCA provides that an exempt wholesale generator is not considered to be an electric utility company. An exempt wholesale generator is permitted to sell capacity and electricity in the wholesale markets, but not in the retail markets.

If an exempt wholesale generator is subject to a "material change" in facts that might affect its continued eligibility for exempt wholesale generator status, within 60 days of such material change, the exempt wholesale generator must (1) file a written explanation of why the material change does not affect its exempt wholesale generator status, (2) file a new application for exempt wholesale generator status, or (3) notify the FERC that it no longer wishes to maintain exempt wholesale generator status.

CALENERGY GENERATION--FOREIGN

The Philippine Congress has passed the Electric Power Industry Reform Act of 2001, which is aimed at restructuring the Philippine power industry, privatization of the NPC and introduction of a competitive electricity market, among other initiatives. The implementation of the bill may have an adverse impact on the Company's future operations in the Philippines and the Philippines power industry as a whole, the effect of which is not yet determinable and estimable.

In connection with an interagency review of approximately 40 independent power project contracts in the Philippines, the Casecnan Project (along with four other unrelated projects) has reportedly been identified as raising legal and financial questions and, with those projects, has been prioritized for renegotiation. The Philippine Projects, have also reportedly been identified as raising financial questions. No written report has yet been issued with respect to the interagency review, and the timing and nature of steps, if any, that the Philippine Government may take in this regard are not known. To the extent disputes arise under the Philippine Projects' agreements with respect to the Philippines Projects'

83

obligations, rights and remedies thereunder, such disputes will be determined by international arbitration in a neutral forum conducted in accordance with the rules of the International Chamber of Commerce or UNCITRAL, as applicable.

Representatives of CE Casecnan, together with certain current and former Philippine government officials, also have been requested to appear, and have appeared, before a Philippine Senate committee which has independently raised questions and made allegations with respect to the Casecnan Project's tariff structure and implementation. No further hearings are scheduled at this time.

HOMESERVICES

The Department of Housing and Urban Development and the Federal Home Administration, or FHA, lender guidelines prohibit the collection of a broker-fee from FHA financed buyers where the FHA lender is affiliated with the real estate broker or where there is no buyer-broker agreement. The majority of HomeServices' subsidiaries have been charging a broker fee to their buyers and sellers, except in circumstances where the FHA guidelines prohibit it. Nonetheless, HomeServices is working with the FHA to change the lenders' guidelines to permit collection of these fees.

PIPELINE SAFETY REGULATION

Our pipeline operations are subject to regulation by the United States Department of Transportation under the Natural Gas Pipeline Safety Act of 1969, as amended, relating to design, installation, testing, construction, operation and management of our pipeline system. The Natural Gas Pipeline Safety Act requires any entity that owns or operates pipeline facilities to comply with applicable safety standards, to establish and maintain inspection and maintenance plans and to comply with such plans. We conduct internal audits of our facilities every four years, with more frequent reviews of those we deem higher risk. The United States Department of Transportation routinely audits our pipeline. Compliance issues that arise during these audits or during the normal course of business are addressed on a timely basis.

The aging pipeline infrastructure in the United States has led to heightened regulatory and legislative scrutiny of pipeline safety and integrity practices. The Natural Gas Pipeline Safety Act was amended by the Pipeline Safety Act of 1992 to require the Department of Transportation's Office of Pipeline Safety to consider protection of the environment when developing minimum pipeline safety regulations. In addition, the amendments require that the Department of Transportation issue pipeline regulations concerning, among other things, the circumstances under which emergency flow restriction devices should be required, training and qualification standards for personnel involved in maintenance and operation, and requirements for periodic integrity inspections, as well as periodic inspection of facilities in navigable waters which could pose a hazard to navigation or public safety. In addition, the amendments narrowed the scope of our gas pipeline exemption pertaining to underground storage tanks under the Resource Conservation and Recovery Act. While the effect of new legislation, which has been passed by Congress but not yet signed by the President, on us is still being determined, we expect to spend the capital or make the operational changes necessary to comply with all pipeline integrity legislation. Northern Natural Gas and Kern River currently project that they will make significant expenditures to meet these new regulations.

We believe our subsidiaries' pipeline operations comply in all material respects with the Natural Gas Pipeline Safety Act, but the industry, including our subsidiaries, could be required to incur additional capital expenditures and increased costs depending upon final regulations issued by the Department of Transportation under the Natural Gas Pipeline Safety Act.

ENVIRONMENTAL REGULATION

DOMESTIC

We are subject to a number of federal, state and local environmental laws and health and other regulations affecting many aspects of our present and future operations in the United States. Such laws and regulations generally require us to obtain and comply with a wide variety of licenses, permits and

84

other approvals. No assurance can be given that in the future all necessary permits and approvals will be obtained or renewed and all applicable statutes and regulations complied with. In addition, regulatory compliance for the construction of new power facilities and gas pipeline operations is a costly and time-consuming process, and intricate and rapidly changing environmental regulations may require major expenditures for permitting or other compliance issues and may 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. We believe that our operating power facilities and gas pipeline operations are currently in material compliance with all applicable federal, state and local laws and regulations. However, we cannot assure you that existing regulations will not be revised or that new regulations will not be adopted or become applicable to us which could have an adverse impact on our operating costs and operations.

In accordance with the requirements of Section 112 of the Clean Air Act Amendments of 1990, the EPA has performed a study of the hazards to public health reasonably anticipated to occur as a result of emissions of hazardous air pollutants by electric utility steam generating units. In December 2000, after research and monitoring of mercury emissions, the EPA concluded that it is appropriate and necessary to regulate mercury emissions from coal-fired generating units. It is anticipated that rules will be developed to regulate these emissions in 2003 or 2004 with reductions of mercury emissions effective in 2007. The cost to MidAmerican Energy of reducing its mercury emissions would depend on available technology at the time, but could be material.

In July 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 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). The standards were subjected to legal proceedings, and in February 2001, United States Supreme Court upheld the constitutionality of the standards, though remanding the issue of implementation of the ozone standard to the EPA. As a result of a decision rendered by the United States Circuit Court of Appeals for the District of Columbia, the EPA is moving forward in implementation of the ozone and fine particulate standards and is analyzing existing monitoring data to determine attainment status.

The impact of the new standards on us is currently unknown. MidAmerican Energy's generating stations may be subject to emission reductions if the stations are located in nonattainment areas or contribute to nonattainment areas in other states. As part of state implementation plans to achieve attainment of the standards, MidAmerican Energy could be required to install control equipment on its generating stations or decrease the number of hours during which these stations operate.

The ozone and fine particulate matter standards could also, in whole or in part, be superceded by one of a number of multi-pollutant emission reduction proposals currently under consideration at the federal level. In July 2002, legislation was introduced in Congress to implement the Administration's "Clear Skies Initiative," calling for the reduction in emissions of sulfur dioxide, nitrogen oxides and mercury through a cap-and-trade system. Reductions would begin in 2008 with additional emission reductions being phased in through 2018. While legislative action is necessary for this or other multi-pollutant emission reduction initiatives to become effective, MidAmerican Energy has implemented a planning process that forecasts the site-specific controls and actions required to meet emissions reductions of this nature.

Since the adoption of the United Nations Framework on Climate Change in 1992, there has been a worldwide effort to reduce greenhouse gas, or GHG, emissions to 1990 levels or below. In December 1997, the U.S. participated in the Kyoto, Japan negotiations, where the basis of a Climate Change treaty was formulated. Under the treaty, known as the Kyoto Protocols, the United States would have an overall reduction target of 7% in GHG emissions from 1990 levels by 2008-2012. To date, the Senate has not ratified the Kyoto Protocols. In addition, President Bush has recently indicated his opposition to the Kyoto Protocols. However, given the widespread international and public support for the reduction of GHG emissions, it is not unlikely that GHG reduction regulations will come to pass, even if not related to the Kyoto Protocols. At this time, we cannot estimate the potential impact of such regulations on us or our subsidiaries.

85

In 2001, the state of Iowa passed legislation that, in part, requires rate-regulated utilities to develop a multi-year plan and budget for managing regulated emissions from their generating facilities in a cost-effective manner. MidAmerican Energy's proposed plan and associated budget was filed with the IUB on April 1, 2002, in accordance with state law. MidAmerican Energy expects the IUB to rule on the prudence of such plan during the first or second quarter of 2003. MidAmerican Energy is required to file updates to such plan at least every two years.

MidAmerican Energy's proposed plan provides its projected air emission reductions considering current proposals being debated at the federal level and describes a coordinated long-range plan to achieve these air emission reductions. MidAmerican Energy's proposed plan also provides specific actions to be taken at each coal-fired generating facility and related costs and timing for each action.

MidAmerican Energy's proposed plan outlines $732.0 million in environmental investments to existing coal-fired generating units, some of which are jointly owned, over a nine-year period from 2002 through 2010. MidAmerican Energy's share of these investments is $546.6 million, $67.9 million of which is projected to be incurred during the 2002-2005 rate freeze period. Such plan also identifies expenses that will be incurred at the generating facilities to operate and maintain the environmental equipment installed as a result of such plan.

Following the expiration on December 31, 2005 of the rate settlement agreement which was approved by the IUB on December 21, 2001, MidAmerican Energy's proposed plan suggests the use of an adjustment mechanism for recovery of such plan's costs, similar to the tracking mechanisms for cost recovery of renewable energy and energy efficiency expenditures that are presently part of MidAmerican Energy's regulated electric rates. See "Regulation--MidAmerican Energy" for a discussion of the settlement agreement.

Federal, state and local environmental laws and regulations currently have, and future modifications may have, the effect of increasing the lead time for the construction of new facilities, significantly increasing the total cost of new facilities, requiring modification of our existing facilities, increasing the risk of delay on construction projects, increasing our cost of waste disposal and possibly reducing the reliability of service we provide and the amount of energy available from our facilities. Any of such items could have a substantial impact on amounts required to be expended by us in the future.

Under various federal, state and local environmental laws and regulations, a current or previous owner or operator of any facility, including an electric generating facility, may be required to investigate and remediate past releases or threatened releases of hazardous or toxic substances or petroleum products located at the facility, and may be held liable to a governmental entity or to third parties for property damage, personal injury and investigation and remediation costs incurred by a party in connection with any releases or threatened releases. These laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986, impose liability without regard to whether the owner knew of or caused the presence of the hazardous substances, and courts have interpreted liability under such laws to be strict and joint and several. The cost of investigation, remediation or removal of substances may be substantial. In connection with the ownership and operation of facilities, we and our subsidiaries may be liable for such costs. Even at those sites where we are not presently aware of any contamination that currently requires remediation, given the use of hazardous substances at each facility and their locations, often within areas that have a long history of industrial use, it is possible that we will discover currently unknown contamination or that future spills or other causes of contamination will occur. As a result, it is possible that we may become liable for remediation.

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

MidAmerican Energy has evaluated or is evaluating 27 properties that were, at one time, sites of gas manufacturing plants in which it may be a potentially responsible party. The purpose of these evaluations

86

is to determine whether waste materials are present, whether the materials constitute an environmental or health risk, and whether MidAmerican Energy has any responsibility for remedial action. Investigations of the sites are at various stages, and MidAmerican Energy has conducted ten removal actions to date and is continuing to evaluate several of the sites to determine the appropriate site remedies, if any, necessary to obtain site closure from the agencies.

MidAmerican Energy estimates the range of possible costs for investigation, remediation and monitoring for the sites discussed above to be $16 million to $30 million. MidAmerican Energy's estimate of the probable cost for these sites as of September 30, 2002 was $18 million. The estimate consists of $1 million for investigation costs, $6 million for remediation costs, $9 million for ground water treatment and monitoring costs and $2 million for closure and administrative costs. This estimate has been recorded as a liability and a regulatory asset for future recovery. MidAmerican Energy projects that these amounts will be paid or incurred over the next five years.

Accruals for probable remediation costs are established based on site-specific estimates and are evaluated and revised quarterly as appropriate based on additional information obtained during investigation and remedial activities. The estimated recorded liability 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. Insurance recoveries have been received for some of the sites under investigation. Those recoveries are intended to be used principally for accelerated remediation, as specified by the IUB, and are recorded as a regulatory liability. Additionally, as viable potentially responsible parties are identified, those parties are evaluated for potential contributions, and cost recovery is pursued when appropriate.

Although the timing of potential incurred costs and recovery of costs in MidAmerican Energy's rates may affect the results of operations in individual periods, management believes that the outcome of issues related to the remediation of former manufactured gas plant facilities will not have a material adverse effect on our financial position, results of operations or cash flows.

UNITED KINGDOM

CE Electric UK's businesses are subject to numerous regulatory requirements with respect to the protection of the environment.

The United Kingdom government introduced new contaminated land legislation in April 2000 that requires companies to:

o put in place a program for investigating the company's history to identify problem sites for which it is responsible;

o make a clear commitment to meeting responsibilities for cleaning up those sites;

o provide funding to make sure that this can happen; and

o make commitments public.

CE Electric UK is in the process of completing the evaluation work on the three sites that may be subject to the legislation. Exploratory work with an environmental remediation company is in progress on these sites.

The Environmental Protection Act (Disposal of PCB's and other Dangerous Substances) Regulations 2001 were introduced on May 5, 2000. The regulations required that transformers containing over 50 parts per million of PCB's and other dangerous substances be registered with the Environment Agency by July 31, 2000. Transformers containing 500 parts per million had to be de-contaminated by December 31, 2000. CE Electric UK has registered 380 items above 50 parts per million, decontaminated 120 items and informed the Environment Agency that it is continuing with its sampling, labeling and registration program. These regulations are not expected to have a material impact on us.

The Groundwater Regulations seek to prevent listed hazardous substances from entering groundwater and strengthens the United Kingdom Environment Agency's powers to require additional

87

protective measures, especially in areas of important groundwater supplies. Mineral oils and hydrocarbons are included in the list of more tightly controlled substances, or List I substances. This affects the high voltage fluid filled electricity cable network incorporating an insulating fluid that is currently in List I. The existing voluntary Operating Code of Practice, as agreed between the Agency and the Electricity Supply Industries, is undergoing revision through the services of the Electricity Association to address the regulatory changes. The existing voluntary Operating Code of Practice is, and any revised Operating Code of Practice will be, incorporated into the operating practices of NED and YED. Any revisions which are made are not expected to have a material impact on us.

The Oil Storage Regulations began to become effective in 2002 and require the introduction of secondary containment measures (bunding) for all above ground oil storage locations where the capacity is more than 200 liters. The primary containers must be in sound condition, leak free, and positioned away from vehicle traffic routes. The secondary containment must be impermeable to water and oil (without drainage valve) and be subject to routine maintenance. The capacity of the bund must be sufficient to hold up to 110% of the largest stored vessel or 25% of the maximum stored capacity, whichever is the greater. The full impact of the regulations is being phased in over the next three years. On March 1, 2002, these regulations came into effect for all new oil storage facilities. On September 1, 2003, the regulations become effective for existing storage facilities at "significant risk" (i.e. within 10 meters of a water course), and on September 1, 2005 the regulations come into effect for all remaining storage facilities. A detailed study of the impacts has been carried out and a plan of action prepared to ensure compliance. We expect that the cost of compliance with such regulations will not have a material adverse impact.

The Electricity Act 1989 obligates either the United Kingdom Secretary of State or the Director General of Electric Supply to take into account the effect of electricity generation, transmission and supply activities on the physical environment when approving applications for the construction of overhead power lines. The Electricity Act requires CE Electric UK to consider the desirability of preserving natural beauty and the conservation of natural and man-made features of particular interest when it formulates proposals for development in connection with certain of its activities. CE Electric UK mitigates the effects its proposals have on natural and man-made features and administers an environmental assessment when it intends to lay cables, construct overhead lines or carry out any other development in connection with its licensed activities. We expect that the cost of compliance with these obligations and the mitigation thereof will not have a material adverse impact.

CE Electric UK's policy is to carry out its activities in such a manner as to minimize the impact of its works and operations on the environment, and in accordance with environmental legislation and good practice. There have not been any significant regulatory environmental compliance issues and there are no material legal or administrative proceedings pending against CE Electric UK with respect to any environmental matter.

Environmental laws and regulations in the United Kingdom currently have, and future modifications may have, the effect of requiring modification of CE Electric UK's facilities, increasing its cost of waste disposal and possibly reducing the reliability of service it provides and the amount of energy available from its facilities. Any of such items could have a substantial impact on amounts required to be expended by CE Electric UK in the future.

PHILIPPINES

On June 23, 1999, the Philippine Congress enacted the Philippine Clean Air Act of 1999. The related implementing rules and regulations were adopted in November 2000. The law as written would require the Upper Mahiao, Mahanagdong and Malitbog projects, which we collectively refer to as the Leyte Projects, to comply with a maximum discharge of 200 grams of hydrogen sulfide per gross megawatt hour of output by June 2004. On November 13, 2002, the Secretary of the Philippine Department of Environmental and Natural Resources issued Memorandum Circular, or MC, 2002-13 designating geothermal areas as "special airsheds." PNOC-EDC has advised us that the MC exempts the Upper Mahiao, Mahanagdong and Malitbog plants from the need to comply with the point-source emission standards of the Clean Air Act. The Leyte Projects intend to seek confirmation of the impact of the MC from PNOC-EDC and from the Philippine Department of Environmental and Natural Resources.

88

NUCLEAR REGULATION

Each licensee of a nuclear facility is required to provide financial assurance for the cost of decommissioning its licensed nuclear facility. In general, decommissioning of a nuclear facility means the obligation to safely remove the facility from service and restore the property to a condition allowing unrestricted use by the operator.

Based on information presently available, we expect to contribute approximately $41 million during the period 2002 through 2006 to an external trust established for the investment of funds for decommissioning the Quad Cities station. Approximately 55% of the fair value of the trust's funds are now invested in domestic corporate debt and common equity securities. The remainder is invested in investment grade municipal and United States Treasury bonds. The Quad Cities station decommissioning costs properly charged to Iowa customers are included in base rates, and recovery of any increases in those amounts must be sought through the normal ratemaking process.

As a result of a July 31, 2002 Settlement Agreement and Release relating to a restructuring of the power purchase contract between MidAmerican Energy and NPPD, MidAmerican Energy will no longer be accruing for decommissioning costs for the Cooper Nuclear Station. Refer to note 12H of our notes to consolidated financial statements for the nine months ended September 30, 2002 contained in this prospectus for a discussion of the settlement and contract restructuring.

MidAmerican Energy maintains financial protection against catastrophic loss associated with its interest in the Quad Cities station through a combination of insurance purchased by Exelon Generation Company, LLC (the operator and joint owner of the Quad Cities station), insurance purchased directly by MidAmerican Energy and the mandatory industry-wide loss funding mechanism afforded under the Price-Anderson Amendments Act of 1988. The general types of coverage are: nuclear liability, property coverage and nuclear worker liability.

Exelon Generation purchased nuclear liability insurance for the Quad Cities station 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 Secondary Financial Protection program under which the licensees 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 Energy's aggregate maximum potential share of an assessment for the Quad Cities station is approximately $44 million per incident, payable in installments not to exceed $5 million annually.

The property insurance covers property damage, stabilization and decontamination of the facility, disposal of the decontaminated material and premature decommissioning arising out of a covered loss. For the Quad Cities station, Exelon Generation purchased primary and excess property insurance protection for the combined interests in the Quad Cities station, with coverage limits totaling $2.1 billion. MidAmerican Energy also directly purchased extra expense/business interruption coverage for its share of replacement power and/or other extra expenses in the event of a covered accidental outage at the Quad Cities station. The property and related coverages purchased directly by MidAmerican Energy and by Exelon Generation, which includes the interests of MidAmerican Energy, are underwritten by an industry mutual insurance company and contain provisions for retrospective premium assessments should two or more full policy-limit losses occur in one policy year. Currently, the maximum aggregate retrospective amounts that could be assessed against MidAmerican Energy from industry mutual policies for its obligations associated with the Quad Cities station total $6.3 million.

The master nuclear worker liability coverage, which was purchased by Exelon Generation for the Quad Cities station, is an industry-wide guaranteed-cost policy with an aggregate limit of $200 million for the nuclear industry as a whole, which is in effect to cover worker tort claims in nuclear-related industries.

89

LEGAL PROCEEDINGS

In addition to the proceedings described below, we and our subsidiaries are currently parties to various items of litigation or arbitration, none of which are reasonably expected by us to have a material adverse effect on us.

CASECNAN CONSTRUCTION ARBITRATION

On February 12, 2001, the contractor for the Casecnan Project, a consortioum consisting of Cooperativa Muratori Cementisti CMC di Ravenna and Impresa Pizzarotti & C. Spa., working together with Siemens A.G. and Sulzer Hydro Ltd., which we collectively refer to as the Contractor, filed a Request for Arbitration with the International Chamber of Commerce seeking an extension of the Guaranteed Substantial Completion Date by up to 153 days through August 31, 2001 resulting from various alleged force majeure events. In its March 20, 2001 Supplement to Request for Arbitration, the Contractor requested compensation for alleged additional costs of approximately $4 million it incurred from the claimed force majeure events to the extent it is unable to recover from its insurer. On April 20, 2001, the Contractor filed a further supplement seeking an additional compensation for damages of approximately $62 million for the alleged force majeure event (and geologic conditions) related to the collapse of the surge shaft. The Contractor also has alleged that the circumstances surrounding the placing of the Casecnan Project into commercial operation on December 11, 2001 amounted to a repudiation of the Construction Contract and has filed a claim for unspecified quantum meruit damages. CE Casecnan believes all such allegations and claims are without merit and is vigorously contesting the Contractor's claims. The arbitration is being conducted applying New York law and in accordance with the rules of the International Chamber of Commerce.

Hearings have been held in connection with this arbitration in July 2001, September 2001, January 2002 and March 2002. As part of those hearings, on June 25, 2001, the arbitration tribunal temporarily enjoined CE Casecnan from making calls on the demand guaranty posted by Banca di Roma in support of the Contractor's obligations to CE Casecnan for delay liquidated damages. As a result of the continuing nature of that injunction, on April 26, 2002, CE Casecnan and the Contractor mutually agreed that no demands would be made on the Banca di Roma demand guaranty except pursuant to an arbitration award. As of September 30, 2002, however, CE Casecnan has received approximately $6.0 million of liquidated damages from demands made on the demand guarantees posted by Commerzbank on behalf of the Contractor. In November 2002, hearings were held on the Contractor's claim with respect to the alleged unenforceability of the delay liquidated damages clause. On November 7, 2002, the International Chamber of Commerce issued the arbitration tribunal's partial award with respect to the Contractor's force majeure and geologic conditions claims. The arbitration panel awarded the Contractor 18 days of schedule relief in the aggregate for all of the force majeure events and awarded the Contractor $3.8 million with respect to the cost of the collapsed surge shaft. All of the Contractor's other claims that were heard by the arbitration tribunal were denied.

Further hearings on the Contractor's repudiation and quantum meruit claims and certain other matters are scheduled for January 2003. These claims, and the alleged unenforceability of the delay liquidated damages clause, have not been ruled on by the arbitration tribunal.

CASECNAN SHAREHOLDER LITIGATION

Pursuant to the share ownership adjustment mechanism in the CE Casecnan shareholder agreement, which is based upon pro forma financial projections of the Casecnan Project prepared following commencement of commercial operations, in February 2002, CE Casecnan, through its indirect wholly owned subsidiary CE Casecnan Ltd., advised the minority shareholder LaPrairie Group Contractors (International) Ltd., or LPG, that our indirect ownership interest in CE Casecnan had increased to 100% effective from commencement of commercial operations. On July 8, 2002, LPG filed a complaint in the Superior Court of the State of California, City and County of San Francisco against, inter alia, CE Casecnan Ltd. and us. In the complaint, LPG seeks compensatory and punitive damages for alleged breaches of the shareholder agreement and alleged breaches of fiduciary duties allegedly owed by CE Casecnan Ltd. and us to LPG. The complaint also seeks injunctive relief against all defendants and a declaratory judgment that LPG is entitled to maintain its 15% interest in CE Casecnan. The impact, if any, of this litigation on us cannot be determined at this time.

90

CASECNAN NIA ARBITRATION

Under the terms of an agreement between CE Casecnan and NIA regarding the Casecnan Project, NIA has the option of timely reimbursing CE Casecnan directly for certain taxes CE Casecnan has paid. If NIA does not so reimburse CE Casecnan, the taxes paid by CE Casecnan result in an increase in the Water Delivery Fee under the Casecnan Project agreement. The payment of certain other taxes by CE Casecnan results automatically in an increase in the Water Delivery Fee. As of September 30, 2002, CE Casecnan has paid approximately $54.4 million in taxes which as a result of the foregoing provisions had resulted in an increase in the Water Delivery Fee. NIA has failed to pay the portion of the Water Delivery Fee each month which relates to the payment of these taxes by CE Casecnan. As a result of this non-payment, on August 19, 2002, CE Casecnan filed a Request for Arbitration against NIA, seeking payment of such portion of the Water Delivery Fee and enforcement of the relevant provision of the Casecnan Project agreement going forward. The arbitration will be conducted in accordance with the rules of the International Chamber of Commerce.

MALITBOG ARBITRATION

On October 16, 2000, VGPC commenced arbitration against PNOC-EDC by serving it with a Notice of Arbitration and Statement of Claim alleging that PNOC-EDC breached the Malitbog energy conversion agreement by improperly characterizing certain No Fault Outages as Forced Outage Hours and then deducting them from the total number of hours each month for purposes of determining payments due to VGPC. On December 22, 2000, VGPC filed an Amended Statement of Claim pursuant to which VGPC added a claim that PNOC-EDC breached the Malitbog agreement by refusing to accept VGPC's specified Nominated Capacity for contract years July 25, 1999 to July 25, 2000, and July 25, 2000 to July 25, 2001. A Second Amended Statement of Claim was filed on March 9, 2001 to add an issue related to the proper duration of annual scheduled maintenance on the Malitbog plant. VGPC intends to vigorously pursue its claims in this proceeding. Hearings were conducted from June 24, 2002 to July 5, 2002 in Sydney, Australia. On November 27, 2002, the arbitration panel issued a unanimous award which states that PNOC-EDC is obligated to pay for all the hours that VGPC spent on Scheduled Maintenance in the year 2000 to the extent that the total number of days of Scheduled Outage has not exceeded 45 days. The award also orders PNOC-EDC to accept VGPC's Nominated Capacity for project years through 2002 and to pay all amounts owed to VGPC in this regard. Furthermore, the award declares that VGPC can only declare no fault outages if VGPC is not at fault, but places the burden of proof in this regard on PNOC-EDC. Also, the award orders VGPC to pay PNOC-EDC $1.6 million in costs. The award orders VGPC and PNOC-EDC to work together to attempt to agree on the amounts owed under the terms of the order and if the parties cannot reach an agreement, each party is to make submissions to the arbitration panel by the middle of January 2003.

MAHANAGDONG ARBITRATION

On September 25, 2002, CE Luzon commenced arbitration against PNOC-EDC alleging that PNOC-EDC breached the Mahanagdong energy conversion agreement by refusing to accept CE Luzon's Nominated Capacity for contract years July 25, 2001 to July 25, 2002 and July 25, 2002 to July 25, 2003. CE Luzon intends to vigorously pursue its claim in this proceeding. The arbitration will be conducted in accordance with the rules of the International Chamber of Commerce.

PIPELINE LITIGATION

In 1998, the United States Department of Justice informed the then current owners of Kern River and Northern Natural Gas that Jack Grynberg, an individual, had filed claims in the United States District Court for the District of Colorado under the False Claims Act against such entities and certain of their subsidiaries including Kern River and Northern Natural Gas. Mr. Grynberg has also filed claims against numerous other energy companies and alleges that the defendants violated the False Claims Act in connection with the measurement and purchase of hydrocarbons. The relief sought is an unspecified amount of royalties allegedly not paid to the federal government, treble damages, civil penalties, attorneys' fees and costs. On April 9, 1999, the United States Department of Justice announced that it

91

declined to intervene in any of the Grynberg qui tam cases, including the actions filed against Kern River and Northern Natural Gas in the United States District Court for the District of Colorado. On October 21, 1999, the Panel on Multi-District Litigation transferred the Grynberg qui tam cases, including the ones filed against Kern River and Northern Natural Gas, to the United States District Court for the District of Wyoming for pre-trial purposes. Motions to dismiss the complaint, filed by various defendants including Northern Natural Gas and Williams, which was the former owner of Kern River, were denied on May 18, 2001. In connection with the purchase of Kern River from Williams in March 2002, Williams agreed to indemnify us against any liability for this claim; however, no assurance can be given as to the ability of Williams to perform on this indemnity should it become necessary. No such indemnification was obtained in connection with the purchase of Northern Natural Gas in August 2002. We believe that the Grynberg cases filed against Kern River and Northern Natural Gas are without merit and Williams, on behalf of Kern River pursuant to its agreement to indemnify us, and Northern Natural Gas, intends to defend these actions vigorously.

On June 8, 2001, a number of interstate pipeline companies, including Kern River and Northern Natural Gas, were named as defendants in a nationwide class action lawsuit which had been pending in the 26th Judicial District, District Court, Stevens County Kansas, Civil Department against other defendants, generally pipeline and gathering companies, since May 20, 1999. The plaintiffs allege that the defendants have engaged in mismeasurement techniques that distort the heating content of natural gas, resulting in an alleged underpayment of royalties to the class of producer plaintiffs. In November 2001, Kern River and Northern Natural Gas, along with the coordinating defendants, filed a motion to dismiss under Rules 9B and 12B of the Kansas Rules of Civil Procedure. In January 2002, Kern River and most of the coordinating defendants filed a motion to dismiss for lack of personal jurisdiction. The court has yet to rule on these motions. The plaintiffs filed for certification of the plaintiff class on September 16, 2002. Williams has agreed to indemnify us against any liability associated with Kern River for this claim; however, no assurance can be given as to the ability of Williams to perform on this indemnity should it become necessary. Williams, on behalf of Kern River and other entities, anticipates joining with Northern Natural Gas and other defendants in contesting certification of the plaintiff class. Kern River and Northern Natural Gas believe that this claim is without merit and that Kern River's and Northern Natural Gas' gas measurement techniques have been in accordance with industry standards and its tariff.

(1) The awards shown in the foregoing table are made pursuant to the Long-Term Incentive Partnership Plan, or LTIP, which provides that awards vest equally over five years with any unvested balances forfeited upon termination of employment unless the participant retires at or above age 55 with at least 5 years of service in which case the participant will receive any unvested portion of the award. Vested balances are paid to the participant at the time of termination. Once an award is fully vested, the participant may elect to defer or receive payment of part or all of the award. Messrs. Sokol and Abel are not participants in the LTIP. Awards are credited or reduced with annual interest or loss based on a composite of funds or indices.

(2) "Target" and "Threshold" payouts are equivalent with the LTIP.

(3) Because Mr. Stepien is no longer our employee, the maximum payout does not apply.

COMPENSATION OF DIRECTORS

All directors, excluding Messrs. Sokol, Abel, Buffett and Walter Scott, are paid an annual retainer fee of $20,000 and a fee of $500 per day for attendance at Board and Committee meetings. Directors who are our employees are not entitled to receive such fees. All directors are reimbursed for their expenses incurred in attending Board meetings.

RETIREMENT PLANS

We maintain a Supplemental Retirement Plan for Designated Officers, which we refer to as the Supplemental Plan, to provide additional retirement benefits to designated participants, as determined by the Board of Directors. Messrs. Sokol, Abel, Stepien and Goodman are participants in the Supplemental Plan. The Supplemental Plan provides annual retirement benefits up to sixty-five percent of a participant's Total Cash Compensation in effect immediately prior to retirement, subject to a $1 million maximum retirement benefit. "Total Cash Compensation" means the highest amount payable to a participant as monthly base salary during the five years immediately prior to retirement multiplied by 12 plus the

96

average of the participant's last three years awards under an annual incentive bonus program and special, additional or non-recurring bonus awards, if any, that are required to be included in Total Cash Compensation pursuant to a participant's employment agreement or approved for inclusion by the Board. Participants must be credited with five years service in order to be eligible to receive benefits under the Supplemental Plan. Each of our Named Executive Officers has or will have five years of credited service with us as of their respective normal retirement age and will be eligible to receive benefits under the Supplemental Plan. A participant who elects early retirement is entitled to reduced benefits under the Supplemental Plan, however, in accordance with their respective employment agreements, Messrs. Sokol and Abel are eligible to receive the maximum retirement benefit at age 47. A survivor benefit is payable to a surviving spouse under the Supplemental Plan. Benefits from the Supplemental Plan will be paid out of general corporate funds; however, through a rabbi trust, we maintain life insurance on the participants in amounts expected to be sufficient to fund the after-tax cost of the projected benefits. Deferred compensation is considered part of the salary covered by the Supplemental Plan.

The supplemental retirement benefit will be reduced by the amount of the participant's regular retirement benefit under the MidAmerican Energy Company Cash Balance Retirement Plan, which we refer to as the MidAmerican Retirement Plan, that became effective January 1, 1997, and by benefits under the Iowa-Illinois Gas and Electric Company Supplemental Retirement Plan, which we refer to as the Iowa-Illinois Supplemental Plan, as applicable.

The MidAmerican Retirement Plan replaced retirement plans of predecessor companies that were structured as traditional, defined benefit plans. Under the MidAmerican Retirement Plan, each participant has an account, for record keeping purposes only, to which credits are allocated each payroll period based upon a percentage of the participant's salary paid in the current pay period. In addition, all balances in the accounts of participants earn a fixed rate of interest that is credited annually. The interest rate for a particular year is based on the constant maturity Treasury yield plus seven-tenths of one percentage point. At retirement or other termination of employment, an amount equal to the vested balance then credited to the account is payable to the participant in the form of a lump sum or a form of annuity for the entire benefit under the MidAmerican Retirement Plan. Mr. Anderson is a participant in this plan.

The table below shows the estimated aggregate annual benefits payable under the Supplemental Plan and the MidAmerican Retirement Plan. The amounts exclude Social Security and are based on a straight life annuity and retirement at ages 55, 60 and 65. Federal law limits the amount of benefits payable to an individual through the tax qualified defined benefit and contribution plans, and benefits exceeding such limitation are payable under the Supplemental Plan.

EMPLOYMENT AGREEMENTS

Pursuant to his employment agreement Mr. Sokol serves as Chairman of our Board of Directors and Chief Executive Officer. The employment agreement provides that Mr. Sokol is to receive an annual base

97

salary of not less than $750,000, senior executive employee benefits and annual bonus awards that shall not be less than $675,000. Subject to an annual renewal provision, such agreement is scheduled to expire on August 21, 2003.

The employment agreement provides that we may terminate the employment of Mr. Sokol with cause, in which case we are to pay to him any accrued but unpaid salary and a bonus of not less than the minimum annual bonus, or due to death, permanent disability or other than for cause, including a change in control, in which case Mr. Sokol is entitled to receive an amount equal to three times the sum of his annual salary then in effect and the greater of his minimum annual bonus or his average annual bonus for the two preceding years, as well as three years of accelerated option vesting plus continuation of his senior executive employee benefits (or the economic equivalent thereof) for three years. If Mr. Sokol resigns, we are to pay to him any accrued but unpaid salary and a bonus of not less than the annual minimum bonus, unless he resigns for good reason in which case he will receive the same benefits as if he were terminated other than for cause.

In the event Mr. Sokol has relinquished his position as Chief Executive Officer and is subsequently terminated as Chairman of the Board due to death, disability or other than for cause, he is entitled to any accrued but unpaid salary plus an amount equal to the aggregate annual salary that would have been paid to him through the fifth anniversary of the date he commenced his employment solely as Chairman of the Board, the immediate vesting of all of his options and the continuation of his senior executive employee benefits (or the economic equivalent thereof) through this fifth anniversary. If Mr. Sokol relinquishes his position as Chief Executive Officer but offers to remain employed as the Chairman of the Board, he is to receive a special achievement bonus equal to two times the sum of his annual salary then in effect and the greater of his minimum annual bonus or his average annual bonus for the two preceding years, as well as two years of accelerated option vesting.

Under the terms of separate employment agreements between us and each of Messrs. Abel and Goodman, each of such executives is entitled to receive two years base salary continuation, payments in respect of average bonuses for the prior two years and two years continued option vesting in the event we terminate his employment other than for cause. If such persons were terminated without cause, Messrs. Sokol, Abel and Goodman would currently be entitled to be paid approximately $12,375,000, $3,330,000 and $1,006,000, respectively, without giving effect to any tax related provisions.

Pursuant to a shareholders agreement, following March 14, 2003, Walter Scott, Jr. or any of the Scott Family Interests would be able to require Berkshire Hathaway to purchase, for an agreed value or an appraised value, any or all of Walter Scott, Jr.'s and the Scott Family Interests' shares of our common stock, provided that Berkshire Hathaway is then a purchaser of a type which is able to consummate such a purchase without causing it or any of its affiliates or us or any of our subsidiaries to become subject to regulation as a registered holding company or a subsidiary of a registered holding company under PUHCA. Berkshire Hathaway is not currently such a purchaser. The consummation of such a transaction could result in a change in control with respect to us.

Our Amended and Restated Articles of Incorporation provide that each share of the Zero Coupon Convertible Preferred Stock is convertible at the option of the holder thereof into one conversion unit, which is one share of our common stock subject to certain adjustments as described in our articles, upon the occurrence of a Conversion Event. A "Conversion Event" includes (1) any conversion of Zero Coupon Convertible Preferred Stock that would not cause the holder of the shares of common stock issued upon conversion (or any affiliate of such holder) or us to become subject to regulation as a registered holding company or as a subsidiary of a registered holding company under PUHCA either as a result of the repeal or amendment of PUHCA, the number of shares involved or the identity of the holder of such shares and (2) a Company Sale. A "Company Sale" includes our involuntary or voluntary liquidation, dissolution, recapitalization, winding-up or termination and any merger, consolidation or sale of all or substantially all of our assets. The conversion by Berkshire Hathaway of its shares of Zero Coupon Convertible Preferred Stock into our common stock could result in a change in control with respect to beneficial owership of our voting securities as calculated pursuant to Rule 13d-3(d) under the Securities Exchange Act.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Under a subscription agreement with us, Berkshire Hathaway has agreed to purchase, under certain circumstances, additional 11% trust issued mandatorily redeemable preferred securities in the event preferred securities outstanding prior to the closing of our acquisition by a private investor group on March 14, 2000 are tendered for conversion to cash by the current holders.

We provided a guarantee in favor of a third party lender in connection with a $1,663,998.75 loan from such lender to our President, Gregory E. Abel, in March of 2000. The loan matures on April 1, 2010. The proceeds of this loan were used by Mr. Abel to purchase 47,475 shares of our common stock. Such common stock (together with 8,465 additional shares of common stock owned by Mr. Abel) also secures the loan. The entire original principal amount of the loan and the guarantee remain presently outstanding.

In order to finance our $275 million preferred stock investment in Williams, on March 7, 2002, we sold to Berkshire Hathaway shares of our zero coupon convertible preferred stock. In order to finance our acquisition of Kern River, on March 12, 2002, we sold to Berkshire Hathaway and/or its consolidated subsidiaries shares of our no par, zero coupon convertible preferred stock for $127 million and $323 million of 11% mandatorily redeemable preferred securities of our subsidiary trust due March 12, 2012 with scheduled principal payments beginning in 2005. In order to finance our acquisition of Northern Natural Gas, on August 16, 2002, we sold to Berkshire Hathaway and/or its consolidated subsidiaries $950 million of 11% mandatorily redeemable preferred securities of our subsidiary trust due August 31, 2012 with scheduled principal payments beginning in 2003. Messrs. Warren E. Buffett and Walter Scott, Jr. are members of the Board of Directors of Berkshire Hathaway. Messrs. Buffett and Marc D. Hamburg are executive officers of Berkshire Hathaway. Each of Messrs. Buffett, Hamburg and Walter Scott serves on our Board of Directors and participates in deliberations regarding executive officer compensation.

On March 6, 2002, we purchased options to purchase shares of our common stock from Mr. David L. Sokol, our Chairman and Chief Executive Officer. The options purchased had exercise prices ranging from $18.50 to $24.22. We paid Mr. Sokol an aggregate amount of $27,122,550, which is equal to the difference between his option exercise prices and an agreed upon per share value. Mr. Sokol serves on our Board of Directors and participates in deliberations regarding executive officer compensation.

100

In July 2002, we purchased 557,686 options to purchase shares of HomeServices common stock from directors, officers and employees of HomeServices. The options purchased had exercise prices ranging from $11.3125 to $15.00. We paid an aggregate of $4,268,392, which is equal to the difference between the option exercise prices and an agreed upon per share value.

We have not purchased any other options or securities from our stockholders, directors or executive officers since January 1, 2002.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

There is no compensation committee of the Board of Directors. All members of the Board of Directors participate in deliberations regarding executive officer compensation. Messrs. Sokol and Abel are current officers and employees. Mr. Walter Scott is a former officer. Mr. Jaros is a former officer and employee. See --"Certain Relationships and Related Transactions."

DESCRIPTION OF THE NOTES

The original notes were, and the exchange notes will be, issued pursuant to an indenture, dated as of October 4, 2002, between the Company and The Bank of New York, as trustee. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

The following description is a summary of the material provisions of the indenture and the related registration rights agreement. It does not restate those agreements in their entirety. We urge you to read the indenture and the registration rights agreement because they, and not this description, define your rights as a holder of the notes. The definitions of certain capitalized terms used in the following summary are set forth below under "--Definitions."

GENERAL

The indenture does not limit the aggregate principal amount of the debt securities that may be issued thereunder and provides that debt securities may be issued from time to time in one or more series.

The notes were initially offered in the aggregate principal amount of $700,000,000. We may, without the consent of the holders, increase such principal amount in the future on the same terms and conditions and with the same CUSIP number(s) as the notes.

The notes were issued in two series. The 2007 notes were issued in an aggregate principal amount of $200,000,000. The 2007 notes bear interest at the rate of 4.625% per annum and will mature on October 1, 2007. The 2012 notes were issued in an aggregate principal amount of $500,000,000. The 2012 notes bear interest at the rate of 5.875% per annum and will mature on October 1, 2012. Interest on the notes is payable semi-annually in arrears on each January 31 and July 31, commencing January 31, 2003, to the holders thereof at the close of business on the preceding January 15 and July 15, respectively. Interest on the notes is computed on the basis of a 360-day year of twelve 30-day months.

The original notes were, and the exchange notes will be, issued without coupons and in fully registered form only in denominations of $1,000 and any integral multiple of $1,000.

The Company files certain reports and other information with the SEC in accordance with the requirements of Sections 13 and 15(d) under the Exchange Act. See "Where You Can Find More Information." In addition, at any time that Sections 13 and 15(d) cease to apply to the Company, the Company has covenanted in the indenture to file comparable reports and information with the trustee and the SEC, and mail such reports and information to holders of notes at their registered addresses, for so long as any notes remain outstanding.

If (1) the registration statement of which this prospectus is a part is not declared effective by the SEC within 270 days after the date on which the original notes were issued, (2) a shelf registration statement with respect to the resale of the notes is not declared effective by the SEC within 150 days after the Company's obligation to file such shelf registration statement arises (but in any event not prior to 270 days after the date on which the original notes were issued) or (3) any of the foregoing registration statements (or the prospectuses related thereto) after being declared effective by the SEC cease to be so effective or usable (subject to certain exceptions) in connection with resales of the original notes or exchange notes for the periods specified and in accordance with the registration rights agreement, the interest rate on the notes that are then subject to such cessation or other registration default will increase by 0.5% from and including the date on which any such event occurs until such event ceases to be continuing. The registration rights are more fully described under "Exchange Offer--Liquidated Damages."

Any 2007 original notes that remain outstanding after the consummation of the exchange offer, together with all 2007 exchange notes issued in connection with the exchange offer, will be treated as a single class of securities under the indenture. Any 2012 original notes that remain outstanding after the consummation of the exchange offer, together with all 2012 exchange notes issued in connection with the exchange offer, will be treated as a single class of securities under the indenture.

102

OPTIONAL REDEMPTION

GENERAL

The notes of each series are redeemable in whole or in part, at the option of the Company at any time, at a redemption price equal to the greater of:

(1) 100% of the principal amount of the series of notes being redeemed; or

(2) the sum of the present values of the remaining scheduled payments of principal of and interest on the series of notes being redeemed discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points,

plus, for (1) or (2) above, whichever is applicable, accrued interest on such notes to the date of redemption.

Notice of redemption shall be given not less than 30 days nor more than 60 days prior to the date of redemption. If fewer than all the notes are to be redeemed, selection of notes of a series for redemption will be made by the trustee in any manner the trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price (as defined below), from and after the date of redemption the notes or portions of notes called for redemption will cease to bear interest, and the holders of those notes will have no right in respect of those notes except the right to receive the applicable Redemption Price.

OPTIONAL REDEMPTION PROVISIONS

Under the procedures described above, the price payable upon the optional redemption at any time of a note (the "Redemption Price") is determined by calculating the present value (the "Present Value") at such time of each remaining payment of principal of or interest on such note and then totaling those Present Values. If the sum of those Present Values is equal to or less than 100% of the principal amount of such note, the Redemption Price of such note will be 100% of its principal amount (redemption at par). If the sum of those Present Values is greater than 100% of the principal amount of such note, the Redemption Price of such note will be such greater amount (redemption at a premium). In no event may a note be redeemed optionally at less than 100% of its principal amount.

The Present Value at any time of a payment of principal of or interest on a note is calculated by applying to such payment the discount rate (the "Discount Rate") applicable to such payment. The Discount Rate applicable at any time to payment of principal of or interest on a note equals the equivalent yield to maturity at such time of a fixed rate United States treasury security having a maturity comparable to the maturity of such payment plus 37.5 basis points, such yield being calculated on the basis of the interest rate borne by such United States treasury security and the price at such time of such security. The United States treasury security employed in the calculation of a Discount Rate (a "Relevant Security") as well as the price and equivalent yield to maturity of such Relevant Security will be selected or determined by an Independent Investment Banker.

Whether the sum of the Present Values of the remaining payments of principal of and interest on a note to be redeemed optionally will or will not exceed 100% of its principal amount and, accordingly, whether such note will be redeemed at par or at a premium will depend on the Discount Rate used to calculate such Present Values. Such Discount Rate, in turn, will depend upon the equivalent yield to maturity of a Relevant Security, which yield will itself depend on the interest rate borne by, and the price of, the Relevant Security. While the interest rate borne by the Relevant Security is fixed, the price of the Relevant Security tends to vary with interest rate levels prevailing from time to time. In general, if at a particular time the prevailing level of interest rates for a newly issued United States treasury security having a maturity comparable to that of a Relevant Security is higher than the level of interest rates for newly issued United States treasury securities having a maturity comparable to such Relevant Security prevailing at the time the Relevant Security was issued, the price of the Relevant Security will be lower than its issue price. Conversely, if at a particular time the prevailing level of interest rates for a newly

103

issued United States treasury security having a maturity comparable to that of a Relevant Security is lower than the level of interest rates prevailing for newly issued United States treasury securities having a maturity comparable to the Relevant Security at the time the Relevant Security was issued, the price of the Relevant Security will be higher than its issue price.

Because the equivalent yield to maturity on a Relevant Security depends on the interest rate it bears and its price, an increase or a decrease in the level of interest rates for newly issued United States treasury securities with a maturity comparable to that of a Relevant Security above or below the levels of interest rates for newly issued United States treasury securities having a maturity comparable to the Relevant Security prevailing at the time of issue of the Relevant Security will generally result in an increase or a decrease, respectively, in the Discount Rate used to determine the Present Value of a payment of principal of or interest on a note. An increase or a decrease in the Discount Rate, and therefore an increase or a decrease in the levels of interest rates for newly issued United States treasury securities having a maturity comparable to the Relevant Security, will result in a decrease or an increase, respectively, of the Present Value of a payment of principal of or interest on a note. In other words, the Redemption Price varies inversely with the levels of interest rates for newly issued United States treasury securities having a maturity comparable to the Comparable Treasury Issue. As noted above, however, if the sum of the Present Values of the remaining payments of principal of and interest on a note proposed to be redeemed is less than its principal amount, such note may only be redeemed at par.

SINKING FUND

The notes are not subject to any mandatory sinking fund.

RANKING

The notes are general, unsecured senior obligations of the Company and rank pari passu in right of payment with all other existing and future senior unsecured obligations of the Company and senior in right of payment to all existing and future subordinated obligations of the Company. The notes are effectively subordinated to all existing and future secured obligations of the Company and to all existing and future obligations of the Company's Subsidiaries. At September 30, 2002, the Company's outstanding indebtedness was approximately $2.0 billion (excluding $2.1 billion in aggregate principal amount of the Company's trust preferred securities, the Company's guarantees and letters of credit in respect of subsidiary indebtedness aggregating approximately $235 million and the Company's completion guarantee issued in favor of the lenders under Kern River's $875 million construction loan facility in connection with Kern River's 2003 Expansion Project). In addition, the Company's subsidiaries have significant amounts of indebtedness. At September 30, 2002, the Company's consolidated subsidiaries' and joint ventures' total outstanding indebtedness was approximately $7.1 billion, which does not include $453 million, representing the Company's share of outstanding indebtedness of CE Gen. This amount also does not include trade debt of the Company's subsidiaries. See "Capitalization."

COVENANTS

Except as set forth under "--Defeasance and Discharge--Covenant Defeasance" below, for so long as any notes remain outstanding, the Company will comply with the terms of the covenants set forth below.

RESTRICTIONS ON LIENS

The Company is not permitted to pledge, mortgage, hypothecate or permit to exist any pledge, mortgage or other Lien upon any property or assets at any time directly owned by the Company to secure any indebtedness for money borrowed which is incurred, issued, assumed or guaranteed by the Company ("Indebtedness for Borrowed Money"), without making effective provisions whereby the outstanding notes will be equally and ratably secured with any and all such Indebtedness for Borrowed Money and with any other Indebtedness for Borrowed Money similarly entitled to be equally and ratably secured; provided however, that this restriction does not apply to or prevent the creation or existence of:

104

(1) any Liens existing prior to the issuance of the original notes;

(2) purchase money Liens which do not exceed the cost or value of the purchased property or assets;

(3) any Liens not to exceed 10% of Consolidated Net Tangible Assets; and

(4) any Liens on property or assets granted in connection with extending, renewing, replacing or refinancing in whole or in part the Indebtedness for Borrowed Money (including, without limitation, increasing the principal amount of such Indebtedness for Borrowed Money) secured by Liens described in the foregoing clauses (1) through
(3), 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 the Company proposes to pledge, mortgage or hypothecate or permit to exist any pledge, mortgage or other Lien upon any property or assets at any time directly owned by it to secure any Indebtedness for Borrowed Money, other than as permitted by clauses (1) through (4) of the previous paragraph, the Company will give prior written notice thereof to the trustee and the Company will, prior to or simultaneously with such pledge, mortgage or hypothecation, effectively secure all the notes equally and ratably with such Indebtedness for Borrowed Money.

The foregoing covenant does not restrict the ability of the Company'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.

CONSOLIDATION, MERGER, CONVEYANCE, SALE OR LEASE

The Company is not permitted to 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 the Company, unless (1) the Company 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 the Company's obligations under the notes and under the indenture and (2) immediately before and after such transaction, no event of default under the indenture shall have occurred and be continuing.

Except for a sale of the consolidated properties and assets of the Company substantially as an entirety as provided above, and other than properties or assets required to be sold to conform with laws or governmental regulations, the Company is not 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 (1) 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 the Company and its Subsidiaries, including, without limitation, any of the lines of business in which the Company or any of its Subsidiaries is engaged on the date of such sale or disposition, and (2) the Company 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 the Company as cash or Cash Equivalents or used to retire Indebtedness for Borrowed Money of the Company (other than Indebtedness for Borrowed Money which is subordinated to the notes) and its Subsidiaries.

PURCHASE OF NOTES UPON A CHANGE OF CONTROL

Upon the occurrence of a Change of Control, each holder of the notes will have the right to require that the Company repurchase all or any part of such holder's notes 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.

105

The Change of Control provisions may not be waived by the trustee or by the board of directors of the Company, 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 notes of any series, in the event that the Company or its Subsidiaries incur additional Debt, whether through recapitalizations or otherwise.

Within 30 days following a Change of Control, the Company will mail a notice to each holder of the notes of each series with a copy to the trustee, stating the following:

(1) that a Change of Control has occurred and that such holder has the right to require the Company to purchase such holder's notes 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) that after the Purchase Date interest on such note will continue to accrue (except as provided in clause (5));

(5) that any note 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 note of any series purchased pursuant to a Change of Control Offer will be required to surrender the note of such series, with the form entitled "Option of Holder To Elect Purchase" on the reverse of the note 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 notes of such series the holder delivered for purchase, and a statement that such holder is withdrawing his election to have such notes of such series purchased; and

(8) that holders that elect to have their notes of any series purchased only in part will be issued new notes having a principal amount equal to the portion of the notes of the series that were surrendered but not tendered and purchased.

On the Purchase Date, the Company will (1) accept for payment all notes of any series or portions thereof tendered pursuant to the Change of Control Offer,
(2) deposit with the trustee money sufficient to pay the purchase price of all notes of such series or portions thereof so tendered for purchase and (3) deliver or cause to be delivered to the trustee the notes of such series properly tendered together with an officer's certificate identifying the notes of such series or portions thereof tendered to the Company for purchase. The trustee will promptly mail, to the holders of the notes 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 note of the same series having a principal amount equal to any portion of such holder's notes 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 notes 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.

106

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.

EVENTS OF DEFAULT

An event of default with respect to the notes of any series is defined in the indenture as being any one of the following events:

(1) default as to the payment of interest on any note of that series for 30 days after payment is due;

(2) default as to the payment of principal of, or premium, if any, on any note of that series or as to any payment required in connection with a Change of Control;

(3) failure to make a Change of Control Offer required under the covenants described under "Purchase of Notes Upon a Change of Control" above or a failure to purchase the notes of that series tendered in respect of such Change of Control Offer;

(4) default in the performance, or breach, of any covenant, agreement or warranty of the Company contained in the indenture and the notes of that series and such failure continues for 30 days after written notice is given to the Company by the trustee or to the Company and the trustee by the holders of at least a majority in aggregate principal amount outstanding of the notes of that series, as provided in the indenture;

(5) default on any other Debt of the Company or any Significant Subsidiary
(other than Debt that is Non-Recourse to the Company) if either (x) such default results from failure to pay principal of such Debt in excess of $100 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 Debt that is Non-Recourse to the Company) that is in default as to principal, or the maturity of which has been accelerated, aggregates $100 million or more;

(6) 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 $100 million (excluding (i) the amount thereof covered by insurance or by a bond written by a person other than an affiliate of the Company and (ii) judgments that are Non-Recourse to 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; and

(7) certain events involving bankruptcy, insolvency or reorganization of the Company or any of its Significant Subsidiaries.

The indenture provides 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 notes and any payment required in connection with a Change of Control) if the trustee considers it in the interest of holders to do so.

The indenture provides that if an event of default with respect to the notes 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 (i) in the case of any event of default described in clause (1) or (2) above, the holders of at least 33% in aggregate principal amount of the notes of that series then outstanding, or
(ii) in the case of any other event of default, the holders of at least a majority in aggregate principal amount of the notes of that series then outstanding, may declare the principal of and any accrued interest on all notes 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 notes of that series or any payment required in connection with a Change of Control) may be waived by the holders of a majority in principal amount of the notes of that series then outstanding. If an event of default due to the

107

bankruptcy, insolvency or reorganization of the Company or a Significant Subsidiary occurs, the indenture provides that the principal of and interest on all notes of that series will become immediately due and payable without any action by the trustee, the holders of notes or any other person.

The holders of a majority in principal amount of the notes of any series 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 notes of such series, subject to certain limitations specified in the indenture, provided that the holders of notes of such series must have offered to the trustee reasonable indemnity against expenses and liabilities.

The indenture requires the annual filing by the Company with the trustee of a written statement as to its knowledge of the existence of any default in the performance and observance of any of the covenants contained in the indenture.

MODIFICATION OF THE INDENTURE

The indenture 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 notes at the time outstanding, to modify the indenture or the rights of the holders of the series of notes, except that no such modification may (1) extend the stated maturity of the principal of or any installment of interest on the notes, reduce the principal amount thereof or the interest rate thereon, reduce any premium payable on redemption or purchase thereof, impair the right of any holder to institute suit for the enforcement of any such payment on or after the stated maturity thereof or make any change in the covenants regarding a Change of Control or the related definitions without the consent of the holder of each of the series of notes so affected, or (2) reduce the percentage of any series of notes, the consent of the holders of which is required for any such modification, without the consent of the holders of all series of notes then outstanding.

DEFEASANCE AND DISCHARGE

LEGAL DEFEASANCE

The indenture provides that the Company will be deemed to have paid and will be discharged from any and all obligations in respect of the notes of 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)(3)(y) below), and the provisions of the indenture will cease to be applicable with respect to such notes of such series (except for, among other matters, certain obligations to register the transfer or exchange of such notes of such series, to replace stolen, lost or mutilated notes of such series, to maintain paying agents 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 and unpaid interest on the applicable notes, on the respective stated maturities of the notes or, if the Company makes arrangements satisfactory to the trustee for the redemption of the notes prior to their stated maturity, on any earlier redemption date in accordance with the terms of the indenture and the applicable notes;

(B) the Company has delivered to the trustee:

(1) 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 notes on the applicable dates, which opinion of counsel must be based upon a ruling of the Internal Revenue Service to

108

the same effect or a change in applicable federal income tax law or related Treasury regulations after the date of the indenture, 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;

(2) an opinion of counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940; and

(3) an opinion of counsel to the effect that either (x) after the passage of 123 days following the deposit referred to in clause (A) above, 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) above 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 referred to in clause (A) above on a pro forma basis, no event of default under the indenture, 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)(3)(y) above) during the period ending on the 123rd day after the date of such deposit, and such deposit and discharge will not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which the Company is a party or by which the Company is bound; and

(D) if at such time the notes are listed on a national securities exchange, the Company has delivered to the trustee an opinion of counsel to the effect that the notes will not be delisted as a result of such deposit, defeasance and discharge.

COVENANT DEFEASANCE

The indenture further provides that the provisions of the covenants described herein under "Covenants--Restrictions on Liens", "--Consolidation, Merger, Conveyance, Sale or Lease" and "--Purchase of Notes Upon a Change of Control," clauses (3) and (4) under "Events of Default" with respect to such covenants, clause (2) under "Events of Default" with respect to offers to purchase upon a Change of Control as described above and clauses (5) and (6) under "Events of Default" will cease to be applicable to the Company and its Subsidiaries upon the satisfaction of the provisions described in clauses (A), (B), (C) and (D) of the preceding paragraph; provided, however, that with respect to such covenant defeasance, the opinion of counsel described in clause (B)(1)(x) above need not be based upon any ruling of the Internal Revenue Service or change in applicable federal income tax law or related Treasury regulations.

DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT

If the Company exercises its option to omit compliance with certain covenants and provisions of the indenture with respect to the notes of any series as described in the immediately preceding paragraph and any series of notes is declared due and payable because of the occurrence of 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 notes at the time of their stated maturity or scheduled redemption, but may not be sufficient to pay amounts due on such notes at the time of acceleration resulting from such event of default. The Company will remain liable for such payments.

GOVERNING LAW

The indenture and the notes are 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.

109

TRUSTEE

The Bank of New York is the trustee under the indenture. An affiliate of the trustee was an initial purchaser in the offering of the original notes. The Bank of New York (or one of its affiliates) currently serves, and may in the future serve, as trustee under indentures evidencing other indebtedness of the Company and its affiliates. The Bank of New York (or one of its affiliates) is also, and may in the future be, a lender under credit facilities for the Company and its affiliates. The Bank of New York is also the exchange agent in the exchange offer.

For purposes of determining compliance with the indenture, in the event that an item of Debt meets the criteria of more than one of the types of Debt described in the above clauses, the Company, in its sole discretion, will classify such item of Debt and only be required to include the amount and type of such Debt in one of such clauses.

"Guarantee" means any obligation, contingent or otherwise, of any person directly or indirectly guaranteeing any Debt of any other person and, without limiting the generality of the foregoing, any Debt obligation, direct or indirect, contingent or otherwise, of such person (1) to purchase or pay (or advance or supply funds for the purchase or payment of) such Debt of such other person (whether arising by virtue of partnership arrangements (other than solely by reason of being a general partner of a partnership), or by agreement to keep-well, to purchase assets, goods, securities or services or to take-or-pay, or to maintain financial statement conditions or otherwise) or (2) entered into for purposes of assuring in any other manner the obligee of such Debt of the payment thereof or to protect such obligee against loss in respect thereof (in whole or in part), provided that the term "Guarantee" will not include endorsements for collection or deposit in the ordinary course of business or the grant of a lien in connection with any Non-Recourse Debt.

GLOBAL NOTES; BOOK-ENTRY SYSTEM

The original notes within each series were, and the exchange notes notes within each series will be, issued under a book-entry system in the form of one or more global notes (each, a "Global Note"). Each Global Note with respect to the original notes was, and each Global Note with respect to the exchange notes will be, deposited with, or on behalf of, a depositary, which is The Depository Trust Company, New York, New York (the "Depositary"). The Global Notes with respect to the original notes were, and the Global Notes with respect to the exchange notes will be, registered in the name of the Depositary or its nominee.

114

The notes will not be issued in certificated form and, except under the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to physical delivery of the notes in certificated form. The Global Notes may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any nominee to a successor of the Depositary or a nominee of such successor.

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 ("Direct Participants") deposit with the Depositary. The Depositary also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct 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, including Euroclear Bank as operator of The Euroclear System ("Euroclear") and Clearstream Banking societe anonyme ("Clearstream"). 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 NASD, 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 Direct and Indirect Participants are on file with the
SEC.

Purchases of the notes under the Depositary system must be made by or through Direct Participants, which will receive a credit for the notes on the Depositary's records. The ownership interest of each actual purchaser of each note ("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 notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in notes, except in the event that use of the book-entry system for the notes is discontinued.

To facilitate subsequent transfers, all notes deposited by Direct Participants with the Depositary will be registered in the name of the Depositary's partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of the Depositary. The deposit of notes with the Depositary and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the notes; the Depositary's records reflect only the identity of the Direct Participants to whose accounts such notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect 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. (nor such other nominee of the Depositary) will consent or vote with respect to the notes. 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 notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Principal (and premium, if any) and interest payments on the notes and any redemption payments will be made to Cede & Co. (or such other nominee as may be requested by an authorized representative

115

of the Depositary). The Depositary's practice is to credit Direct Participants' accounts upon the Depositary's receipt of funds and corresponding detail information from the Company or its agent on the payable date in accordance with their respective holdings shown on the Depositary's records. 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 customers in bearer form or registered in "street name," and will be the responsibility of such Participant and not of the Depositary, the trustee, or the Company or its agent, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal (and premium, if any), interest and any redemption proceeds to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary) is the responsibility of the Company, disbursements of such payments to Direct Participants shall be 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 depositary with respect to the notes at any time by giving reasonable notice to the Company. Under such circumstances, in the event that a successor securities depositary is not obtained, certificated notes 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 successor securities depositary). In that event, certificated notes 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, the initial purchasers and the trustee take no responsibility for the accuracy thereof.

A Global Note 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 Note representing notes of any series is exchangeable, in whole but not in part, for notes of such series in definitive form of like tenor and terms if (1) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Note 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 120 days of receipt by the Company of such notice or of the Company becoming aware of such ineligibility, (2) while such Global Note is subject to the transfer restrictions described in the indenture, the book-entry interests in such Global Note cease to be eligible for Depositary services because such notes are neither
(a) rated in one of the top four categories by a nationally recognized statistical rating organization nor (b) included within a Self-Regulatory Organization system approved by the SEC for the reporting of quotation and trade information of securities eligible for transfer pursuant to Rule 144A under the Securities Act, or (3) the Company in its sole discretion at any time determines not to have such notes represented by a Global Note and notifies the trustee thereof. A Global Note exchangeable pursuant to the preceding sentence shall be exchangeable for notes registered in such names and in such authorized denominations as the Depositary of such Global Note shall direct.

If (1) the exchange offer registration statement is not declared effective by the Exchange Effectiveness Deadline, (2) the shelf registration statement is not declared effective by the Shelf Effectiveness Deadline, or (3) after either the exchange offer registration statement or the shelf registration statement is declared effective, such registration statement or the related prospectus thereafter ceases to be effective or usable (subject to certain exceptions) in connection with resales of notes or exchange notes for the period specified and in accordance with the registration rights agreement (each such event referred to in clauses (1) through (3), a "Registration Default"), additional interest will accrue on the notes subject to such Registration Default at a rate of 0.5% from and including the date on which any such Registration Default occurs to but excluding the date on which all such Registration Defaults have ceased to be continuing. In each case, such additional interest is payable in addition to any other interest payable from time to time with respect to the notes and the exchange notes.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of the material United States federal income tax consequences relevant to the purchase, ownership and disposition of the notes, and does not purport to be a complete analysis of all potential tax effects. This discussion only deals with persons that hold notes as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"), and that purchased the notes for cash at original issue. This discussion does not address all the United States federal income tax consequences that may be relevant to a holder in light of such holder's particular circumstances or to holders subject to special rules, such as financial institutions, banks, partnerships and other pass-through entities, United States expatriates, controlled foreign corporations, passive foreign investment companies, foreign personal holding companies, insurance companies, dealers in securities or currencies, traders in securities, U.S. Holders (defined below) whose functional currency is not the United States dollar, tax-exempt organizations and persons holding the notes as part of a "straddle," "hedge," "conversion transaction" or other integrated transaction.

The discussion is based upon the Code, United States Treasury Regulations issued thereunder, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which are subject to change at any time possibly with retroactive effect.

As used herein, "U.S. Holder" means a beneficial owner of the notes who or that is

o an individual that is a citizen or resident of the United States;

o a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States or a political subdivision thereof;

o an estate, the income of which is subject to United States federal income tax regardless of its source;

o a trust, if a United States court can exercise primary supervision over the administration of the trust and one or more U.S. persons can control all substantial trust decisions, or, if the trust was in existence on August 20, 1996, and has elected to continue to be treated as a U.S. person; or

o a person whose worldwide income or gain is otherwise subject to United States federal income tax on a net income basis.

We have not sought and will not seek any rulings from the Internal Revenue Service, (the "IRS") with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.

PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE TAX CONSEQUENCES DISCUSSED BELOW TO THEIR PARTICULAR SITUATIONS AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.

U.S. HOLDERS

STATED INTEREST

A U.S. Holder must generally include stated interest on a note as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder's method of accounting for U.S. federal income tax purposes.

SALE OR OTHER TAXABLE DISPOSITION OF THE NOTES

A U.S. Holder will generally recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note equal to the difference between the amount realized upon the disposition and the U.S. Holder's adjusted tax basis in the note. Notwithstanding the foregoing, any amounts realized in connection with any sale, exchange, redemption, retirement or other taxable disposition to the extent attributable to accrued interest not previously included in income will be treated

117

as ordinary interest income. A U.S. Holder's adjusted basis in a note generally will be the U.S. Holder's cost therefor. This gain or loss generally will be a capital gain or loss, and if the U.S. Holder is an individual that has held the note for more than one year, such capital gain will generally be subject to tax at a maximum rate of 20%, or 18% if such holder has held the notes for more than five years. A U.S. Holder's ability to deduct capital losses may be limited.

EXCHANGE OFFER

The exchange of original notes for exchange notes pursuant to the exchange offer will not constitute a taxable event for U.S. federal income tax purposes. As a result,

o a U.S. Holder of notes will not recognize taxable gain or loss as a result of the exchange of original notes for exchange notes pursuant to the exchange offer,

o the holding period of the exchange notes will include the holding period of the original notes surrendered in exchange therefor, and

o a U.S. Holder's adjusted tax basis in the exchange notes will be the same as such U.S. Holder's adjusted tax basis in the original notes surrendered in exchange therefor.

CONTINGENT PAYMENTS

In certain circumstances, we may be obligated to pay you amounts in excess of the stated interest and principal payable on the notes. The obligation to make payments of additional interest upon a registration default, and, in certain circumstances, payments upon a change in control, may implicate the provisions of Treasury regulations relating to "contingent payment debt instruments." We intend to take the position that the notes should not be treated as contingent payment debt instruments because of these payments. Assuming such position is respected, a U.S. Holder would be required to include in income the amount of any such payments at the time such payments are received or accrued in accordance with such U.S. Holder's method of accounting for U.S. federal income tax purposes. If the IRS successfully challenged this position, and the notes were treated as contingent payment debt instruments because of such payments, U.S. Holders might, among other things, be required to accrue interest income at higher rates than the stated interest rates on the notes and to treat any gain recognized on the sale or other disposition of a note as ordinary income, subject to tax at the maximum federal rate of 38.6%, rather than as capital gain which may be subject to tax at the maximum federal rate of 20%. The regulations applicable to contingent payment debt instruments have not been the subject of authoritative interpretation and therefore the scope of the regulations is not certain. Purchasers of notes are urged to consult their tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes.

INFORMATION REPORTING AND BACKUP WITHHOLDING

A U.S. Holder may be subject to a backup withholding tax (currently at a rate of 30% but subject to a gradual reduction to 28% for payments made in 2006 through 2010, after which it will increase to 31%) when such holder receives "reportable payments," including interest and principal payments on the notes or proceeds upon the sale or other disposition of such notes. Certain holders (including, among others, corporations and certain tax-exempt organizations) are generally not subject to backup withholding. A U.S. Holder will be subject to this backup withholding tax if such holder is not otherwise exempt and such holder:

o fails to furnish its taxpayer identification number, or TIN, which, for an individual, is ordinarily his or her social security number;

o furnishes an incorrect TIN and the payor has received notice thereof;

o has failed to properly report payments of interest or dividends and the payor has received notice thereof; or

o fails to certify, under penalties of perjury, that it has furnished a correct TIN and that the IRS has not notified the U.S. Holder that it is subject to backup withholding.

118

U.S. Holders should consult their personal tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. The backup withholding tax is not an additional tax and taxpayers may use amounts withheld as a credit against their United States federal income tax liability or may claim a refund as long as they timely provide certain information to the IRS.

We, our paying agent or other withholding agent generally will report to a U.S. Holder of notes and to the IRS the amount of any reportable payments made in respect of the notes for each calendar year and the amount of tax withheld, if any, with respect to such payments.

NON-U.S. HOLDERS

The following discussion is limited to the United States federal income tax consequences relevant to a beneficial owner of a note that is not a U.S. Holder (a "Non-U.S. Holder").

INTEREST

Subject to the discussion of backup withholding below, interest paid to a Non-U.S. Holder will not be subject to United States federal income or withholding tax, provided that:

o such holder does not directly or indirectly, actually or constructively, own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

o such holder is not a controlled foreign corporation that is related to us directly or constructively through stock ownership;

o such holder is not a bank receiving interest on a loan entered into in the ordinary course of its trade or business;

o such interest is not effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States; and

o we, or our paying agent, receive appropriate documentation establishing that the Non-U.S. Holder is not a U.S. person.

A Non-U.S. Holder that does not qualify for exemption from withholding under the preceding paragraph generally will be subject to withholding of United States federal income tax at a 30% rate (or lower applicable treaty rate) on payments of interest on the notes.

If interest on the notes is effectively connected with the conduct by a Non-U.S. Holder of a trade or business within the United States, such interest will be subject to United States federal income tax on a net income basis at the rate applicable to U.S. persons generally (and, with respect to corporate holders, may also be subject to a 30% branch profits tax). If interest is subject to United States federal income tax on a net income basis in accordance with these rules, such payments will not be subject to United States withholding tax so long as the Non-U.S. Holder provides us or our paying agent with the appropriate documentation.

SALE OR OTHER TAXABLE DISPOSITION OF THE NOTES

Subject to the discussion of backup withholding below, any gain realized by a Non-U.S. Holder on the sale, exchange or redemption of a note generally will not be subject to United States federal income tax, unless

o such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States,

o the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are satisfied, or

o the Non-U.S. Holder is subject to tax pursuant to the provisions of United States federal income tax law applicable to certain expatriates.

119

INFORMATION REPORTING AND BACKUP WITHHOLDING

Backup withholding and information reporting generally will not apply to interest payments made to a Non-U.S. Holder in respect of the notes if such Non-U.S. Holder furnishes us or our paying agent with appropriate documentation of such holder's non-U.S. status.

The payment of proceeds from a Non-U.S. Holder's disposition of notes to or through the U.S. office of any broker, domestic or foreign, will be subject to information reporting and possible backup withholding unless such holder certifies as to its non-U.S. status under penalties of perjury or otherwise establishes an exemption, provided that the broker does not have actual knowledge or reason to know that such holder is a U.S. person or that the conditions of an exemption are not, in fact, satisfied.

The payment of the proceeds from a Non-U.S. Holder's disposition of a note to or through a non- United States office of either a United States broker or a non- United States broker that is a U.S.-related person will be subject to information reporting, but not backup withholding, unless such broker has documentary evidence in its files that such Non-U.S. Holder is not a U.S. person and the broker has no knowledge to the contrary, or the Non-U.S. Holder establishes an exemption. For this purpose, a "U.S.-related person" is

o a controlled foreign corporation for United States federal income tax purposes,

o a foreign person 50% or more of whose gross income from all sources for the three-year period ending with the close of its taxable year preceding payment (or for such part of the period that the broker has been in existence) is derived from activities that are effectively connected with the conduct of a United States trade or business, or

o a foreign partnership that is either engaged in the conduct of a trade or business in the United States or of which 50% or more of its income or capital interests are held by U.S. persons.

Neither information reporting nor backup withholding will apply to a payment of the proceeds of a Non-U.S. Holder's disposition of notes by or through a non-United States office of a non-United States broker that is not a United States-related person. Copies of any information returns filed with the IRS may be made available by the IRS, under the provisions of a specific treaty or agreement, to the taxing authorities of the country in which the Non-U.S. Holder resides.

Non-U.S. Holders should consult their own tax advisors regarding the application of withholding and backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from withholding and backup withholding under current Treasury Regulations. In this regard, the current Treasury Regulations provide that a certification may not be relied on if we or our agent (or other payor) knows or has reasons to know that the certification may be false.

Any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Holder will be allowed as a credit against the holder's United States federal income tax liability or may entitle the holder to a refund, provided the required information is furnished timely to the IRS.

120

PLAN OF DISTRIBUTION

Based on existing interpretations of the Securities Act by the staff of the SEC set forth in several no-action letters to third parties, and subject to the immediately following sentence, we believe that the exchange notes that will be issued pursuant to the exchange offer may be offered for resale, resold and otherwise transferred by the holders thereof without further compliance with the registration and prospectus delivery provisions of the Securities Act. However, any purchaser of notes who is an "affiliate" (within the meaning of the Securities Act) of ours or who intends to participate in the exchange offer for the purpose of distributing the exchange notes or a broker-dealer (within the meaning of the Securities Act) that acquired original notes in a transaction other than as part of its market-making or other trading activities and who has arranged or has an understanding with any person to participate in the distribution of the exchange notes: (1) will not be able to rely on the interpretations by the staff of the SEC set forth in the above-mentioned no-action letters; (2) will not be able to tender its original notes in the exchange offer; and (3) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the notes unless such sale or transfer is made pursuant to an exemption from such requirements.

Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for original notes where such original notes were acquired as a result of market-marketing activities or other trading activities. We have agreed that, for a period of 120 days after the expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until _________, 200___, all dealers effecting transactions in the exchange notes may be required to deliver a prospectus.

We will not receive any proceeds from any such sale of exchange notes by broker-dealers. Exchange notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker/dealer and/or the purchasers of any such exchange notes. Any broker-dealer that resells exchange notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such exchange notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of exchange notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letters of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

For a period of 120 days after the expiration date we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holders of the notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

121

NOTICE TO CANADIAN RESIDENTS

Any resale of the notes in Canada must be made under applicable securities laws which will vary depending on the relevant jurisdiction, and which may require resales to be made under available statutory exemptions or under a discretionary exemption granted by the applicable Canadian securities regulatory authority. Note holders resident in Canada are advised to seek legal advice prior to any resale of the notes.

LEGAL MATTERS

Certain legal matters with respect to the exchange notes will be passed upon for us by Willkie Farr & Gallagher, New York, New York.

With respect to the unaudited interim financial information for the periods ended September 30, 2002 and 2001, which is included in this prospectus, Deloitte & Touche LLP have applied limited procedures in accordance with professional standards for a review of such information. However, as stated in their report included in the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2002 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 report 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 of 1933 for their report on the unaudited interim financial information because this report is not a "report" or a "part" of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.

INDEPENDENT ACCOUNTANTS' REPORT

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

We have reviewed the accompanying consolidated balance sheet of MidAmerican Energy Holdings Company and subsidiaries (the Company) as of September 30, 2002, and the related consolidated statements of operations for the three-month and nine-month periods ended September 30, 2002 and 2001, and the related consolidated statements of cash flows for the nine-month periods ended September 30, 2002 and 2001. 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 auditing standards generally accepted in the United States of America, 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 accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated balance sheet of MidAmerican Energy Holdings Company and subsidiaries as of December 31, 2001, and the related consolidated statements of operations, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated January 17, 2002 (March 27, 2002 as to Notes 20.A. and 21 and August 2, 2002 as to Note 23), 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, 2001, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

MIDAMERICAN ENERGY HOLDINGS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

In the opinion of management of MidAmerican Energy Holdings Company and subsidiaries (the "Company"), the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the financial position as of September 30, 2002, and the results of operations for the three months and nine months ended September 30, 2002 and 2001 and the related consolidated statements of cash flows for the nine months ended September 30, 2002 and 2001. The results of operations for the three months and nine months ended September 30, 2002 and 2001 are not necessarily indicative of the results to be expected for the full year.

The consolidated financial statements include the accounts of MidAmerican Energy Holdings Company and its wholly and majority owned subsidiaries. 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 2001 financial statements and supporting note disclosures have been reclassified to conform to the 2002 presentation. Such reclassification did not impact previously reported net income or retained earnings.

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.

It operates three natural gas storage facilities and two liquefied natural gas peaking units for a total storage capacity of 59 billion cubic feet and peak delivery capability of over 1.3 billion cubic feet of natural gas per day.

The Company paid $899.2 million for Northern Natural Gas, net of cash acquired of $1.4 million and transaction costs and working capital adjustments.

The Company is in the process of completing the working capital negotiations and the allocation of the purchase price to the assets and liabilities acquired. The results of operations for Northern Natural Gas are included in the Company's results beginning August 16, 2002.

The recognition of excess of cost over fair value of net assets acquired resulted from various attributes of Northern Natural Gas' operations and business in general. These attributes include, but are not limited to:

o High credit quality shippers contracting with Northern Natural Gas;

o Northern Natural Gas' strong competitive position;

o Strategic location in the high demand Upper Midwest markets;

o Flexible access to an ample supply of low-cost gas;

3. CALENERGY GAS DISPOSAL

In May 2002, CalEnergy Gas, an indirect wholly owned subsidiary of the Company, executed the sale of several of its U.K. natural gas assets to Gaz de France for (pounds sterling)137.0 million (approximately $200 million). CalEnergy Gas sold four natural gas-producing fields located in the southern basin of the U.K. North Sea, including Anglia, Johnston, Schooner and Windermere. The transaction also included the sale of rights in four gas fields (in development/ construction) and three exploration blocks owned by CalEnergy Gas. As a result of the sale, the Company's nine month results ending September 30, 2002 include pre-tax and after-tax income of $54.3 million and $41.3 million, respectively, which includes a write off of non-deductible goodwill of $49.6 million. The three month results ending September 30, 2002 include $21.1 million in tax benefits related to the sale.

Zinc Recovery Project

CalEnergy Minerals, LLC, an indirect wholly owned subsidiary of the Company, is constructing the Zinc Recovery Project. The Zinc Recovery Project is designed to have a capacity of approximately 30,000 metric tons per year and is scheduled to commence commercial operations in 2002. Total project costs of the Zinc Recovery Project are expected to be approximately $244 million, net of damages received from Kvaerner, which is being funded by $140.5 million of debt and the balance from funds provided by the parent company. The Zinc Recovery Project has incurred $213.9 million, net of damages, of such costs through September 30, 2002.

Utility generation, distribution and transmission systems

Through 2007, MidAmerican Energy plans to develop and construct two electric generating plants in Iowa. MidAmerican Energy expects to invest approximately $1.2 billion in the two plants, including the cost of related transmission facilities and allowance for funds used during construction. The two plants may provide approximately 950 megawatts of generating capacity for MidAmerican Energy depending on management's on-going assessment of needs and related factors.

The first project is a 500-megawatt (based on expected accreditation) natural gas-fired combined cycle unit with an estimated cost of $415 million. MidAmerican Energy will own 100% of the plant and operate it. MidAmerican Energy has received a certificate from the Iowa Utilities Board allowing it to construct the plant. Also, on May 29, 2002, the Iowa Utilities Board issued an order that provides the ratemaking principles for the gas-fired plant, thus limiting the regulatory risk of constructing the plant. As a result of that order, MidAmerican Energy is proceeding with the construction of the plant. It is anticipated that the first phase of the project will be completed in 2003, resulting in an additional 310 megawatts of accredited capacity, with the remainder being completed in 2005.

Kern River natural gas pipeline expansion

On July 17, 2002, Kern River received approval from FERC to construct, own and operate a major expansion to its pipeline system (the "2003 Expansion Project"). The 2003 Expansion Project will loop most of Kern River's existing mainline, construct three new compressor stations and upgrade or modify Kern River's six existing compressor stations. The 2003 Expansion Project, which is expected to be completed and operational by May 2003, will increase Kern River's capacity by approximately 900 MMcf per day. Service will be provided under long-term contracts subject to incremental rates. The estimated cost of the expansion is approximately $1.2 billion.

5. OTHER INVESTMENTS

On March 27, 2002, the Company invested $275.0 million in Williams in exchange for shares of 9 7/8 percent cumulative convertible preferred stock of Williams. Dividends are scheduled to be received quarterly, which commenced July 1, 2002. This investment is accounted for under the cost method. The Company is aware that there have been public announcements that Williams' financial condition has deteriorated as a result of reduced liquidity. Williams' senior unsecured debt obligations are currently rated B1 by Moody's, B by Standard & Poor's and B- by Fitch. The Company has not recorded an impairment on this investment as of September 30, 2002, and is monitoring the situation.

In connection with this investment, the Company issued $275.0 million of no par, zero coupon convertible preferred stock to Berkshire Hathaway. Each share of preferred stock is convertible at the option of the holder into one share of the Company's common stock subject to certain adjustments as described in the Company's Amended and Restated Articles of Incorporation.

6. TEESSIDE POWER LIMITED RESTRUCTURING

CE Electric UK Funding, an indirect wholly owned subsidiary of the Company, has a 15.4% interest in Teesside Power Limited ("TPL"). TPL owns and operates an 1,875MW combined cycle gas-fired power plant. Shareholders in TPL had previously utilized TPL's taxable losses with an obligation to reimburse TPL later in the project's life. In May 2002, TPL executed a restructuring and stabilization agreement with its lenders. The contract included an agreement between TPL and its shareholders with respect to the waiver of these repayment obligations. In May 2002, CE Electric UK Funding released $35.7 million due to the repayment obligation being waived which is reflected as a current tax benefit in the provision for income taxes.

7. REAL ESTATE COMPANY ACQUISITIONS

During 2002, HomeServices separately acquired three real estate companies for an aggregate purchase price of approximately $100 million, net of cash acquired, plus working capital and certain other adjustments. For the year ended December 31, 2001, these real estate companies had combined revenue

F-9

of approximately $356 million on 42,000 closed sides representing $13.7 billion of sales volume. Additionally, HomeServices is obligated to pay a maximum earnout of $18.5 million calculated based on 2002 financial performance measures. These purchases were financed using HomeServices' $65 million revolving credit facility and MidAmerican Energy Holdings Company's corporate revolver for $40 million, which was contributed to HomeServices as equity. The Company is in the process of completing the allocation of the purchase price to the assets and liabilities acquired.

8. DEBT ISSUANCES AND REDEMPTIONS

On February 8, 2002, MidAmerican Energy issued $400 million of 6.75% notes due in 2031. The proceeds are being used to refinance existing debt and preferred securities and for other corporate purposes. On March 11, 2002, MidAmerican Energy redeemed all $100 million of its 7.98% MidAmerican-obligated preferred securities of subsidiary trust at 100% of the principal amount plus accrued interest.

On May 1, 2002, MidAmerican Energy reacquired all $26.7 million of its $7.80 series of preferred securities. The first $13.3 million of preferred securities were redeemed at 100% of the principal amount plus accrued dividends, and the remaining $13.4 million was redeemed at 103.9% of the principal amount plus accrued dividends.

On June 21, 2002, Kern River closed on a bank loan facility providing for aggregate loans of up to $875 million to be used for the construction of the Kern River 2003 Expansion Project. The facility, which matures 15 years after the 2003 Expansion Project commences operation, has a variable interest rate which increases over the term of the facility from 1.375% to 4.5% over LIBOR. Kern River has drawn $384.9 million on this facility as of September 30, 2002.

9. ACCOUNTING POLICY CHANGE

Effective January 1, 2001, the Company changed its accounting policy regarding major maintenance and repairs for nonregulated gas projects, nonregulated plant overhaul costs and geothermal well rework costs to the direct expense method from the former policy of monthly accruals based on long-term scheduled maintenance plans for the gas projects and deferral and amortization of plant overhaul costs and geothermal well rework costs over the estimated useful lives. The cumulative effect of the change in accounting principle for 2001 was $4.6 million, net of taxes of $.7 million.

10. ACCOUNTING PRONOUNCEMENTS AND REPORTING ISSUES

On January 1, 2002, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 142, "Goodwill and Other Intangible Assets," which dictates the accounting for acquired goodwill and other intangible assets. SFAS No. 142 requires that amortization of goodwill and indefinite-lived intangible assets be discontinued and that entities disclose net income for prior periods adjusted to exclude such amortization and related income tax effects, as well as a reconciliation from the originally reported net income to the adjusted net income. The Company's related amortization consists of goodwill amortization and the related income tax effect. Following is a reconciliation of net income as originally reported for the periods ended September 30, 2002 and 2001, to adjusted net income (in thousands):

In accordance with SFAS No. 142, the Company has determined its reporting units and has completed the initial impairment testing of goodwill primarily using a discounted cash flow methodology. No impairment was indicated as a result of the initial impairment testing. See Note 14 for allocation of goodwill to reporting units.

F-10

In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 143, "Accounting for Asset Retirement Obligations". SFAS No. 143 requires recognition on the balance sheet of legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or normal operation of such assets. Additionally, at the time an asset retirement obligation (ARO) is recognized, an ARO asset of the same amount is recorded and depreciated. This pronouncement is effective for fiscal years beginning after June 15, 2002. The Company is evaluating the impact that adoption of this standard will have on its consolidated financial statements.

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", which addresses the financial accounting and reporting for the impairment or disposal of long-lived assets. The adoption of SFAS No. 144 on January 1, 2002, did not have any impact on the Company's consolidated financial statements.

The Emerging Issues Task Force (EITF) recently issued EITF Issue No. 02-3, "Recognition and Reporting of Gains and Losses on Energy Trading Contracts Under Issues No. 98-10 and 00-17." In accordance with EITF No. 02-3, all gains and losses on energy trading contracts must be reported net on the income statement, effective for reporting periods ending after July 15, 2002, with all prior periods presented being reclassified to a consistent presentation. MidAmerican Energy's nonregulated wholesale gas and electric marketing activities qualify as "energy trading" contracts under the guidance of EITF No. 98-10. In accordance with EITF Issue No. 02-3, effective September 30, 2002, for MidAmerican Energy, all trading revenues are reported net of the cost of such sales. Previously, such amounts were recorded gross. All prior periods have been reclassified to conform to the net presentation.

11. COMPREHENSIVE INCOME

The differences from net income to total comprehensive income for the Company are due to foreign currency translation adjustments, unrealized holding gains and losses of marketable securities during the periods, and the effective portion of net gains and losses of derivative instruments classified as cash flow hedges. Total comprehensive income for the nine months ended September 30, 2001, includes a transition loss of $3.3 million related to the initial adoption of SFAS No. 133. Total comprehensive income for the Company is shown in the table below (in thousands).

12. COMMITMENTS AND CONTINGENCIES

A. FINANCIAL CONDITION OF EDISON

Southern California Edison Company ("Edison"), a wholly owned subsidiary of Edison International, is a public utility primarily engaged in the business of supplying electric energy to retail customers in Central and Southern California, excluding Los Angeles. Due to reduced liquidity, Edison failed to pay approximately $119 million due under the power purchase agreement with CE Generation affiliates for power delivered in the fourth quarter 2000 and the first quarter 2001. Due to Edison's failure to pay contractual obligations, the CE Generation affiliates had established an allowance for doubtful accounts of approximately $21 million as of December 31, 2001. The final payment of the past due amounts was received from Edison on March 1, 2002. Following the receipt of Edison's payment of past due balances, the CE Generation affiliates released the remaining allowance for doubtful accounts.

B. CASECNAN CONSTRUCTION ARBITRATION

On May 7, 1997, CE Casecnan entered into a fixed-price, date certain, turnkey engineering, procurement and construction contract to complete the construction of the Casecnan Project (the "Construction Contract"). The work under the Construction Contract was conducted by a consortium consisting of Cooperativa Muratori Cementisti CMC di Ravenna and Impresa Pizzarotti & C. Spa., working together with Siemens A.G., Sulzer Hydro Ltd., Black & Veatch and Colenco Power Engineering Ltd. (collectively, the "Contractor").

On November 20, 1999, the Construction Contract was amended to extend the Guaranteed Substantial Completion Date for the Casecnan Project to March 31, 2001. This amendment was approved by the lenders" independent engineer under the Casecnan Indenture. In January 2001, CE Casecnan received a new working schedule from the Contractor that showed a completion date of August 31, 2001. The delay in completion was attributable in part to the collapse in December 2000 of the Casecnan Project's partially completed vertical surge shaft and the need to drill a replacement surge shaft.

Upon receipt of the working schedule, CE Casecnan sought and obtained from the lender's independent engineer approval for a revised construction schedule under the Casecnan Indenture. In connection with the revised schedule, MidAmerican Energy Holdings Company agreed to make available up to $11.6 million of additional funds under certain conditions pursuant to a Shareholder Support Letter dated February 8, 2001 (Shareholder Support Letter). MidAmerican Energy Holdings Company has fully satisfied its obligations under the Shareholder Support Letter.

The receipt of the new working schedule did not change the Guaranteed Substantial Completion Date under the Construction Contract, and the Contractor was still contractually obligated either to complete the Casecnan Project by March 31, 2001, or to pay liquidated damages for the delay in completion. The Casecnan Project entered into commercial operations on December 11, 2001. In 2002, CE Casecnan has received approximately $6.0 million of liquidated damages from demands made on the demand guarantees posted by Commerzbank on behalf of the Contractor.

On February 12, 2001, the Contractor filed a Request for Arbitration with the International Chamber of Commerce seeking an extension of the Guaranteed Substantial Completion Date by up to 153 days through August 31, 2001, resulting from various alleged force majeure events. In its March 20, 2001, Supplement to Request for Arbitration, the Contractor requested compensation for alleged additional costs of approximately $4 million it incurred from the claimed force majeure events to the extent it is unable to recover from its insurer. On April 20, 2001, the Contractor filed a further supplement seeking an additional compensation for damages of approximately $62 million for the alleged force majeure event (and geologic conditions) related to the collapse of the surge shaft. The Contractor has alleged that the circumstances surrounding the placing of the Casecnan Project into commercial operation on December 11, 2001, amounted to a repudiation of the Construction Contract and has filed a claim for unspecified quantum meruit damages. The Contractor also has alleged that the delay liquidated damages clause in the EPC Contract is unenforceable as a penalty. CE Casecnan believes all such allegations and claims are without merit and is vigorously contesting the Contractor's claims. The arbitration is being conducted applying New York law and in accordance with the rules of the International Chamber of Commerce. Although the outcome of the arbitration, as with any litigious proceedings, is difficult to access, CE Casecnan believes it will prevail and receive additional liquidated damages in the arbitration.

On June 25, 2001, the arbitration tribunal temporarily enjoined CE Casecnan from making calls on the demand guaranty posted by Banca di Roma in support of the Contractor's obligations to CE Casecnan for delay liquidated damages. On April 26, 2002, CE Casecnan and the Contractor mutually agreed that no demands would be made on the Banca di Roma demand guaranty except pursuant to a final arbitration award. Hearings on the force majeure claims were held in London from July 2 to 14, 2001, and hearings on the Contractor's April 20, 2001, supplement were held from September 24 to October 3, 2001. Further hearings were held from January 21 to February 1, 2002 and from March 14 to 19, 2002. From November 4 to 6, 2002, hearings were held on the Contractor's claim with respect to the alleged unenforceability of the delay liquidated damages clause. On November 7, 2002, the International Chamber of Commerce issued the arbitration tribunal's partial award with respect to the Contractor's force majeure and geologic

F-12

conditions claims. The arbitral panel awarded the Contractor 18 days of schedule relief in the aggregate for all of the force majeure events and awarded the Contractor $3.8 million with respect to the cost of the collapsed surge shaft. All of the Contractor's other claims that have been heard by the arbitral tribunal were denied.

Further hearings on the Contractor's repudiation and quantum meruit claims are scheduled for January 20 to 23 and 28 to 31, 2003. These claims, and the alleged unenforceability of the delay liquidated damages clause, have not been ruled on by the arbitration tribunal.

C. CASECNAN SHAREHOLDER ISSUE

Pursuant to the share ownership adjustment mechanism in the Casecnan Shareholder Agreement, which is based upon pro forma financial projections of the Casecnan Project prepared following commencement of commercial operations, the Company, through its indirect wholly owned subsidiary CE Casecnan Ltd., has advised the minority shareholder LaPrairie Group Contractors (International) Ltd. ("LPG"), that the Company's ownership interest in CE Casecnan will increase to 100%. On July 8, 2002, LPG filed a complaint in the Superior Court of the State of California, City and County of San Francisco against, inter alia, CE Casecnan Ltd. and MidAmerican Energy Holdings Company. In the complaint, LPG seeks compensatory and punitive damages for alleged breaches of the Shareholder Agreement and alleged breaches of fiduciary duties allegedly owed by the Company and CE Casecnan Ltd. to LPG. The complaint also seeks injunctive relief against all defendants and a declaratory judgment that LPG is entitled to maintain its 15% interest in Casecnan. The impact, if any, of this litigation on the Company cannot be determined at this time.

D. CASECNAN NIA ARBITRATION

In August 2002, CE Casecnan commenced arbitration against the National Irrigation Administration ("NIA") in connection with the Casecnan Project by serving it with a Request for Arbitration under International Chamber of Commerce rules (the "Request for Arbitration"). In the Request for Arbitration, CE Casecnan claimed that NIA has breached its obligations under the Casecnan Project Agreement by failing to reimburse CE Casecnan for certain tax payments and by failing to pay the portion of the Water Delivery Fee under the Casecnan Project Agreement attributable to certain tax payments. The Casecnan Project Agreement provides for arbitration in accordance with International Chamber of Commerce rules by a panel of three arbitrators in Singapore. CE Casecnan is awaiting NIA's formal answer to the Request for Arbitration. CE Casecnan intends to vigorously pursue its claims in these proceedings.

E. MALITBOG ARBITRATION

VGPC and PNOC-EDC have been negotiating with respect to certain disputes concerning the Malitbog energy conversion agreement ("ECA") but have been unable to reach a mutually acceptable resolution. Accordingly, on October 16, 2000, VGPC commenced arbitration against PNOC-EDC by serving it with a Notice of Arbitration and Statement of Claim (the "Notice of Arbitration"). In the Notice of Arbitration, VGPC claimed that PNOC-EDC breached the Malitbog ECA by improperly characterizing certain No Fault Outages as Forced Outage Hours and then deducting them from the total number of hours each month. On December 22, 2000, VGPC filed an Amended Statement of Claim pursuant to which VGPC added a claim that PNOC-EDC breached the Malitbog ECA by refusing to accept VGPC's specified Nominated Capacity for contract years July 25, 1999 to July 25, 2000, and July 25, 2000 to July 25, 2001. A Second Amended Statement of Claim was filed on March 9, 2001, to add the Scheduled Maintenance issue. VGPC is vigorously pursuing its claims in this proceeding. Hearings were conducted from June 24, 2002, to July 5, 2002, in Sydney, Australia, and the Company expects a ruling on these hearings in the fourth quarter of 2002.

F. MAHANAGDONG ARBITRATION

On September 25, 2002, CE Luzon Geothermal Power Company, Inc. ("CE Luzon"), an indirect majority owned subsidiary of the Company, commenced arbitration against PNOC-EDC by serving it with a

F-13

Request for Arbitration (the "Request for Arbitration") under International Chamber of Commerce rules. In the Request for Arbitration, CE Luzon claimed that PNOC-EDC breached the Mahanagdong ECA by refusing to accept CE Luzon's specified Nominated Capacity for contract years July 25, 2001 to July 25, 2002 and July 25, 2002 to July 25, 2003. CE Luzon is awaiting PNOC-EDC's formal answer. CE Luzon intends to vigorously pursue its claims in these proceedings.

G. REGULATORY ENVIRONMENT: PHILIPPINES

The Philippine Congress has passed the Electric Power Industry Reform Act of 2001, which is aimed at restructuring the Philippine power industry, privatization of the NPC and introduction of a competitive electricity market, among other initiatives. The implementation of the bill may have an impact on the Company's future operations and the industry as a whole, the effect of which is not yet determinable and estimable.

In connection with an interagency review of approximately 40 independent power project contracts in the Philippines, the Casecnan Project (along with four other unrelated projects) has reportedly been identified as raising legal and financial questions and, with those projects, has been prioritized for renegotiation. The Company's subsidiaries' Upper Mahiao, Malitbog, and Mahanagdong projects, which, together with the Casecnan Project, collectively the "Philippine Projects", have also reportedly been identified as raising financial questions. No written report has yet been issued with respect to the interagency review, and the timing and nature of steps, if any, that the Philippine Government may take in this regard are not known. To the extent disputes arise under the Philippine Projects' agreements with respect to the Philippines Projects' obligations, rights and remedies thereunder, such disputes will be determined by international arbitration in a neutral forum conducted in accordance with the rules of the International Chamber of Commerce or UNCITRAL, as applicable.

Representatives of CE Casecnan Water and Energy Company, Inc. ("CE Casecnan"), a Philippine corporation, together with certain current and former Philippine government officials, also have been requested to appear, and have appeared, before a Philippine Senate committee which has independently raised questions and made allegations with respect to the Casecnan Project's tariff structure and implementation. No further hearings are scheduled at this time. CE Casecnan has and intends to continue to respond to such questions and to vigorously defend the Casecnan Project against any allegations, which may be made. CE Casecnan believes the allegations made with respect to the Casecnan Project to be without merit.

H. COOPER LITIGATION

On July 23, 1997, Nebraska Public Power District ("NPPD") filed a complaint, in the United States District Court for the District of Nebraska, naming MidAmerican Energy as the defendant and seeking declaratory judgment as to issues under the parties' long-term power purchase agreement for Cooper Nuclear Station ("Cooper") capacity and energy.

On July 31, 2002, MidAmerican Energy and NPPD signed an agreement on the restructuring of the power purchase contract for Cooper. Under the terms of the restructured contract, MidAmerican Energy will pay NPPD through December 31, 2004, a scheduled amount per unit for 380 megawatts of the accredited capacity of Cooper and a minimum of approximately 1.2 million megawatt-hours (MWh) in the last five months of 2002 and approximately 2.5 million MWh in each of 2003 and 2004. NPPD also paid MidAmerican Energy $39.1 million on August 1, 2002.

In December 2000, MidAmerican Energy ceased contributing decommissioning funds to NPPD and maintained a separate fund for estimated Cooper decommissioning costs. At the date of the contract restructuring, $18.3 million had been accrued and retained by MidAmerican Energy in this separate fund. In conjunction with the power purchase contract restructuring, MidAmerican Energy is recognizing the $39.1 million cash payment and the $18.3 million previously accrued for decommissioning into income based on the estimated energy expected to be received for the remainder of the contract.

F-14

Finally, both parties agreed to release each other from any and all claims, past or present, each might have under the power purchase contract prior to being restructured and file to dismiss the litigation currently pending in U.S. District Court.

Under the terms of MidAmerican Energy's power purchase contract with NPPD prior to its restructuring, MidAmerican Energy paid NPPD one-half of the fixed and operating costs of Cooper, excluding depreciation but including debt service, and MidAmerican Energy's share of the nuclear fuel cost, including Department of Energy disposal fees, based on energy delivered. In addition, prior to December 2000, MidAmerican Energy contributed toward payment of one-half of Cooper's project decommissioning costs based on an assumed 2004 shutdown of the plant.

I. KVAERNER ARBITRATION

The Zinc Recovery Project was being constructed by Kvaerner U.S. Inc. ("Kvaerner") pursuant to a date certain, fixed-price, turnkey engineering, procure, construct and manage contract (the "Zinc Recovery Project EPC Contract"). On June 14, 2001, CalEnergy Minerals, LLC issued notices of default, termination and demand for payment of damages to Kvaerner under the Zinc Recovery Project EPC Contract due to failure to meet performance obligations. As a result of Kvaerner's failure to pay monetary obligations under the Zinc Recovery Project EPC Contract, CalEnergy Minerals, LLC drew $29.6 million under the EPC Contract Letter of Credit ("LOC") on July 20, 2001, and claimed the retainage and balance of the contract price. The LOC draw, retainage and balance of the contract price have been accounted for as a reduction of the capitalized costs of the project. CalEnergy Minerals, LLC has entered into a time and materials reimbursable engineer, procure and construction management contract with AMEC E&C Services, Inc. to complete the Zinc Recovery Project.

On May 23, 2002, following various discussions and legal filings, CalEnergy Minerals, LLC and Kvaerner entered into a Settlement Agreement. Under the terms of the agreement, CalEnergy Minerals, LLC retained the amounts drawn under the LOC, the EPC retainage amounts and the EPC contract balance and will pay to Kvaerner three equal installments of $2.25 million payable in January of 2003, 2004 and 2005.

J. PIPELINE LITIGATION

In 1998, the United States Department of Justice informed the then current owners of Kern River and Northern Natural Gas that Jack Grynberg, an individual, had filed claims in the United States District Court for the District of Colorado under the False Claims Act against such entities and certain of their subsidiaries including Kern River and Northern Natural Gas. Mr. Grynberg has also filed claims against numerous other energy companies and alleges that the defendants violated the False Claims Act in connection with the measurement and purchase of hydrocarbons. The relief sought is an unspecified amount of royalties allegedly not paid to the federal government, treble damages, civil penalties, attorneys' fees and costs. On April 9, 1999, the United States Department of Justice announced that it declined to intervene in any of the Grynberg qui tam cases, including the actions filed against Kern River and Northern Natural Gas in the United States District Court for the District of Colorado. On October 21, 1999, the Panel on Multi-District Litigation transferred the Grynberg qui tam cases, including the ones filed against Kern River and Northern Natural Gas, to the United States District Court for the District of Wyoming for pre-trial purposes. Motions to dismiss the complaint, filed by various defendants including Northern Natural Gas and Williams, which was the former owner of Kern River, were denied on May 18, 2001. In connection with the purchase of Kern River from Williams in March 2002, Williams agreed to indemnify us against any liability for this claim; however, no assurance can be given as to the ability of Williams to perform on this indemnity should it become necessary. No such indemnification was obtained in connection with the purchase of Northern Natural Gas in August 2002. We believe that the Grynberg cases filed against Kern River and Northern Natural Gas are without merit and Williams, on behalf of Kern River pursuant to its agreement to indemnify us, and Northern Natural Gas, intends to defend these actions vigorously.

On June 8, 2001, a number of interstate pipeline companies, including Kern River and Northern Natural Gas, were named as defendants in a nationwide class action lawsuit which had been pending in the 26th

F-15

Judicial District, District Court, Stevens County Kansas, Civil Department against other defendants, generally pipeline and gathering companies, since May 20, 1999. The plaintiffs allege that the defendants have engaged in mismeasurement techniques that distort the heating content of natural gas, resulting in an alleged underpayment of royalties to the class of producer plaintiffs. In November 2001, Kern River and Northern Natural Gas, along with the coordinating defendants, filed a motion to dismiss under Rules 9B and 12B of the Kansas Rules of Civil Procedure. In January 2002, Kern River and Northern Natural Gas and most of the coordinating defendants filed a motion to dismiss for lack of personal jurisdiction. The court has yet to rule on these motions. The plaintiffs filed for certification of the plaintiff class on September 16, 2002. Williams has agreed to indemnify us against any liability associated with Kern River for this claim; however, no assurance can be given as to the ability of Williams to perform on this indemnity should it become necessary. Williams, on behalf of Kern River and other entities, anticipates joining with Northern Natural Gas and other defendants in contesting certification of the plaintiff class. Kern River and Northern Natural Gas believe that this claim is without merit and that Kern River's and Northern Natural Gas' gas measurement techniques have been in accordance with industry standards and its tariff.

K. PIPELINE EXPANSION GUARANTEE

On July 17, 2002, Kern River received approval from the FERC to construct, own and operate the 2003 Expansion Project. The 2003 Expansion Project will loop most of Kern River's existing mainline, construct three new compressor stations and upgrade or modify Kern River's six existing compressor stations. The 2003 Expansion Project, which is expected to be completed and operational by May 2003, will increase Kern River's capacity by approximately 900mmcf/day. Service will be provided under long-term contracts subject to incremental rates. The estimated cost of the expansion is approximately $1.2 billion, which will be financed with 70% debt and 30% equity, consistent with Kern River's existing capital structure, the application for the FERC approval described above and the limitations contained in the indenture for Kern River's existing secured senior notes.

Construction will initially be funded with the proceeds of an $875 million credit facility entered into by Kern River on June 21, 2002, until 70% of the projected capitalized costs of the 2003 Expansion Project has been spent. The final 30% of the capitalized costs of the 2003 Expansion Project will be funded with equity from the Company. The credit facility is structured as a two-year construction facility followed by a term loan with a final maturity 15 years after completion of the 2003 Expansion Project. However, Kern River presently intends to refinance the credit facility through a bond offering or other capital markets transaction following completion of the 2003 Expansion Project. Prior to completion of the 2003 Expansion Project, the credit facility lenders will have limited recourse to Kern River and its assets and cash flow, and will have recourse to the Company's completion guarantee described below. Following completion of the 2003 Expansion Project, until such time as the Kern River credit facility is refinanced, the lenders under the credit facility will share equally and ratably with the existing Kern River senior secured noteholders in all of the collateral pledged to such senior secured noteholders.

Pursuant to the Company's completion guarantee, it has guaranteed that "completion" of the 2003 Expansion Project will occur on or prior to the earliest of any abandonment by Kern River of the project, the occurrence of certain other acceleration events and June 30, 2004. The potential acceleration events include any downgrading of the Company's public debt rating to below investment grade by either S&P or Moody's unless a satisfactory substitute guarantor assumes the Company's obligations under the completion guarantee within 60 days after any such downgrade; Berkshire Hathaway ceasing to own at least a majority of the outstanding capital stock of the Company; and certain other customary events of default by the Company. In the completion guarantee, the Company has also agreed to cause capital contributions to be made to Kern River in a minimum aggregate amount of at least $375 million by June 30, 2004 or upon any earlier event of abandonment of the project. For purposes of the Company's completion guarantee, the term "completion" is defined in the Kern River credit agreement to mean satisfaction of a number of conditions, the most significant of which include the requirements that the 2003 Expansion Project be substantially complete and operable and able to permit Kern River to perform its obligations under all of the long-term firm gas transportation service agreements entered into in connection with the 2003 Expansion Project; that the shippers under such agreements shall have begun

F-16

to incur the obligation to pay reservation fees thereunder; and that the FERC shall have authorized Kern River to begin collecting rates under its tariff and its shipper agreements; provided that the 2003 Expansion Project shall still be deemed to have been completed if it is less than substantially complete but it demonstrates at least 80% design capacity and Kern River's debt service coverage ratios as defined in its senior secured note indenture are not less than 1:55 to 1:0. There are a number of other conditions to completion, including requirements that all conditions to completion of the expansion contained in Kern River's senior secured note indenture be satisfied and all of Kern River's obligations under its credit agreement then share pari passu in all collateral available to Kern River's senior secured noteholders. The Company's completion guarantee shall terminate upon the earlier of completion of the 2003 Expansion Project or repayment in full of all obligations under the Kern River credit facility.

L. MANUFACTURED GAS PLANT

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

MidAmerican Energy has evaluated or is evaluating 27 properties that were, at one time, sites of gas manufacturing plants in which it may be a potentially responsible party. The purpose of these evaluations is to determine whether waste materials are present, whether the materials constitute an environmental or health risk, and whether MidAmerican Energy has any responsibility for remedial action. Investigations of the sites are at various stages, and MidAmerican Energy has conducted ten removal actions to date. MidAmerican Energy is continuing to evaluate several of the sites to determine the appropriate site remedies, if any, necessary to obtain site closure from the agencies.

MidAmerican Energy estimates the range of possible costs for investigation, remediation and monitoring for the sites discussed above to be $16 million to $30 million. MidAmerican Energy's estimate of the probable cost for these sites as of September 30, 2002, was $18 million. The estimate consists of $1 million for investigation costs, $6 million for remediation costs, $9 million for ground water treatment and monitoring costs and $2 million for closure and administrative costs. This estimate has been recorded as a liability and a regulatory asset for future recovery. MidAmerican Energy projects that these amounts will be paid or incurred over the next 5 years.

The estimate of probable remediation costs is established on a site-specific basis. Initially, a determination is made as to whether MidAmerican Energy has potential remedial liability for the site and whether information exists to indicate that contaminated wastes remain at the site. When a potential remedial liability exists, the best estimate of projected site closure costs are accrued. The estimates are evaluated and revised quarterly as appropriate based on additional information obtained during investigation and remedial activities. The estimated recorded liabilities for these properties include incremental direct costs of the remediation effort and oversight by the appropriate regulatory authority, 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 liability 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. Insurance recoveries have been received for some of the sites under investigation. Those recoveries are intended to be used principally for accelerated remediation, as specified by the Iowa Utilities Board, and are recorded as a regulatory liability. Additionally, as viable potentially responsible parties are identified, those parties are evaluated for potential contributions, and cost recovery is pursued when appropriate.

Although the timing of potential incurred costs and recovery of 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 the Company's financial position, results of operations or cash flows.

13. SUBSEQUENT EVENTS

On October 4, 2002, the Company issued $200 million of 4.625% Senior Notes due in 2007 and $500 million of 5.875% Senior Notes due in 2012. The proceeds are being used for general corporate

F-17

purposes including to reduce short-term obligations, to make a $150 million equity contribution to Northern Natural Gas, and to make funds available to Kern River for its 2003 Expansion Project.

On October 15, 2002, Northern Natural Gas issued $300 million of 5.375% Senior Notes due in 2012. The proceeds, along with the $150 million equity contribution from the Company, were used to refinance a $450 million short-term debt obligation.

14. SEGMENT INFORMATION

INDEPENDENT AUDITORS' REPORT

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

We have audited the accompanying consolidated balance sheets of MidAmerican Energy Holdings Company (successor to MidAmerican Energy Holdings Company (Predecessor), referred to as "MEHC (Predecessor)") and subsidiaries (the "Company") as of December 31, 2001 and 2000 for the Company, and the related consolidated statements of operations, stockholders' equity, and cash flows for the year ended December 31, 2001 for the Company, for the period January 1, 2000 to March 13, 2000 for MEHC (Predecessor), for the period March 14, 2000 to December 31, 2000 for the Company, and for the year ended December 31, 1999 for MEHC (Predecessor). Our audits also included the financial statement schedules listed in Item 21. These financial statements and financial statement schedules are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. 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 MidAmerican Energy Holdings Company and subsidiaries as of December 31, 2001 and 2000, and the results of their operations and their cash flows for the above stated periods in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly in all material respects the information set forth therein.

As discussed in Note 2 to the consolidated financial statements, in 2001 the Company changed its accounting policy for major maintenance, overhaul and well workover costs.

MIDAMERICAN ENERGY HOLDINGS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS

MidAmerican Energy Holdings Company and its subsidiaries (the "Company" or "MEHC"), is a United States-based privately owned global energy company with publicly traded fixed income securities that generates, distributes and supplies energy to utilities, government entities, retail customers and other customers located throughout the world. Through its subsidiaries the Company is organized and managed on five separate platforms: MidAmerican Energy, CE Electric UK Funding, CalEnergy Generation-Domestic, CalEnergy Generation-Foreign and HomeServices.

On March 14, 2000, the Company and an investor group comprised of Berkshire Hathaway Inc., Walter Scott, Jr., a director of the Company, David L. Sokol, Chairman and Chief Executive Officer of the Company, and Gregory E. Abel, Chief Operating Officer of the Company closed on a definitive agreement and plan of merger whereby the investor group acquired all of the outstanding common stock of the Company (the "Teton Transaction"). As a result of the Teton Transaction, Berkshire Hathaway, Mr. Scott, Mr. Sokol and Mr. Abel own approximately 9.7%, 86%, 3% and 1% of the voting stock respectively.

MIDAMERICAN ENERGY

MidAmerican Energy Company ("MidAmerican Energy") is a regulated public utility principally engaged in the business of generating, transmitting, distributing and selling electric energy and in distributing, selling and transporting natural gas. MidAmerican Energy distributes electricity at the retail level in Iowa, Illinois and South Dakota. It also distributes natural gas at the retail level in Iowa, Illinois, South Dakota and Nebraska. As of December 31, 2001, MidAmerican Energy had approximately 673,000 retail electric customers and 652,000 retail natural gas customers.

In addition to retail sales, MidAmerican Energy sells electric energy and natural gas to other utilities, marketers and municipalities that distribute it to end-use customers. These sales are referred to as sales for resale or off-system sales. It also transports natural gas through its distribution system for a number of end-use customers who have independently secured their supply of natural gas.

A substantial portion of MidAmerican Energy's business still operates in a rate-regulated environment and, accordingly, many decisions for obtaining and using resources are evaluated from an electric and gas regulated business perspective. MidAmerican Energy's operations are seasonal in nature with a disproportionate percentage of revenues and earnings historically being earned in the Company's first and third quarters.

CE ELECTRIC UK FUNDING

The business of CE Electric UK Funding, an indirect wholly owned subsidiary of the Company, consists of Northern Electric plc ("Northern"), an indirect wholly owned subsidiary of the Company, and Yorkshire Power Group Ltd. ("Yorkshire"), an indirect majority owned subsidiary of the Company, and CalEnergy Gas (Holdings) Limited ("CE Gas"), an indirect wholly owned subsidiary of the Company.

Northern's and Yorkshire's operations consist primarily of the distribution of electricity and other auxiliary businesses in the United Kingdom. Through September 21, 2001, Northern's operations also included the supply of electricity and natural gas and the related metering business.

Northern and Yorkshire receive electricity from the national grid transmission system and distribute it to customers' premises using their network of transformers, switchgear and cables. Substantially all of the customers in their distribution service areas are connected to their network and can only be delivered through their distribution system, thus providing Northern and Yorkshire with distribution volume that is stable from year to year. Northern and Yorkshire charge access fees for the use of the distribution system. The prices for distribution are controlled by a prescribed formula that limits increases (and may require decreases) based upon the rate of inflation in the United Kingdom and other regulatory action.

F-26

Northern's supply business was primarily involved in the bulk purchase of electricity, previously through a central pool and from March 27, 2001 on through the New Electricity Trading Agreements ("NETA"), and subsequent resale to individual customers throughout the U.K. The supply business generally is a high volume business that tends to operate at lower profitability levels than the distribution business. Northern also competed to supply gas inside and outside its authorized area. See Note 3.

CE Gas is a gas exploration and production company that is focused on developing integrated upstream gas projects. Its "upstream gas" business consists of the exploration, development and production, including transportation and storage, of gas for delivery to a point of sale into either a gas supply market or a power generation facility. CE Gas holds various interests in the southern basin of the United Kingdom sector of the North Sea. Also, CE Gas has been involved in certain gas development and exploration activities relating to a large gas field prospect in Poland, the EP389 concession in the Perth Basin in Australia and the Yolla discovery in the Bass Basin of Australia.

CALENERGY GENERATION-DOMESTIC

The Company has a 50% ownership interest in CE Generation LLC ("CE Generation") that has interests in ten geothermal plants in the Imperial Valley, California and three natural gas-fired cogeneration plants. For purposes of consistent presentation, plant capacity factors for Vulcan, Hoch (Del Ranch), Turbo, Elmore and Leathers (collectively the "Partnership Projects") are based on capacity amounts of 34, 38, 10, 38, and 38 net MW, respectively, and for Salton Sea I, Salton Sea II, Salton Sea III, Salton Sea IV and Salton Sea V plants (collectively the "Salton Sea Projects") are based on capacity amounts of 10, 20, 50, 40 and 49 net MW, respectively (the Partnership Projects and the Salton Sea Projects are collectively referred to as the "Imperial Valley Projects"). Plant capacity factors for Saranac, Power Resources and Yuma (collectively the "Gas Plants") are based on capacity amounts of 240, 200, and 50 net MW, respectively. Each plant possesses an operating margin that allows for production in excess of the amount listed above. Utilization of this operating margin is based upon a variety of factors and can be expected to vary between calendar quarters, under normal operating conditions. Due to its 50% ownership interest in CE Generation, the Company accounts for CE Generation as an equity investment.

Cordova Energy Company LLC ("Cordova Energy"), an indirect wholly owned subsidiary of the Company, operates a 537 MW gas-fired power plant in the Quad Cities, Illinois area (the "Cordova Project"). The Cordova Project commenced commercial operations on June 19, 2001. Cordova Energy has entered into a power purchase agreement with a unit of El Paso Energy Corporation ("El Paso") in which El Paso will purchase all of the capacity and energy from the project until December 31, 2019. Cordova Energy has exercised an option under the El Paso Power Purchase Agreement to callback 50% of the project output for sales to others for the contract years ending on or prior to May 14, 2004. Cordova Energy subsequently entered into a power purchase agreement with MidAmerican Energy whereby MidAmerican Energy will purchase 50% of the capacity and energy from the Cordova Project until May 14, 2004.

CALENERGY GENERATION-FOREIGN

The Company indirectly owns the Upper Mahiao, Malitbog and Mahanagdong Projects (collectively, the "Leyte Projects"), which are geothermal power plants located on the island of Leyte in the Philippines, and the Casecnan Project, a combined irrigation and hydroelectric power generation project located in the central part of the island of Luzon in the Philippines. The Casecnan Project commenced commercial operations on December 11, 2001. For purposes of consistent presentation, capacity amounts for Upper Mahiao, Malitbog, Mahanagdong and Casecnan are 119, 216, 165 and 150 net MW, respectively. Each plant possesses an operating margin that allows for production in excess of the amount listed above. Utilization of this operating margin is based upon a variety of factors and can be expected to vary between calendar quarters, under normal operating conditions.

HOMESERVICES

HomeServices.Com, Inc. ("HomeServices"), a wholly-owned subsidiary of the Company, is the second largest residential real estate brokerage firm in the United States based on aggregate closed transaction

F-27

sides in 2000 for its various brokerage firm operating subsidiaries. Closed transaction sides mean either the buy side or sell side of any closed home purchase and is the standard term used by industry participants and publications to rank real estate brokerage firms. In addition to providing traditional residential real estate brokerage services, HomeServices cross sells to its existing real estate customers preclosing services, such as mortgage origination and title services, including title insurance, title search, escrow and other closing administrative services, assists in securing other preclosing and postclosing services provided by third parties, such as home warranty, home inspection, home security, property and casualty insurance, home maintenance, repair and remodeling and is developing various related e-commerce services. HomeServices currently operates in the following fourteen states: Minnesota, Iowa, California, Arizona, Kansas, Missouri, Kentucky, Nebraska, Wisconsin, Indiana, Maryland, North Dakota, South Dakota and Georgia. HomeServices generally occupies the number one or number two market share position in each of its major markets based on aggregate closed transaction sides for the year ended December 31, 2001. HomeServices' major markets consist of the following metropolitan areas: Minneapolis and St. Paul, Minnesota; Des Moines, Iowa; Los Angeles and San Diego, California; Omaha, Nebraska; Kansas City, Kansas; Louisville, Kentucky; Springfield, Missouri; Tucson, Arizona; Annapolis, Maryland and Atlanta, Georgia.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Subsidiaries which are less than 100% owned but greater than 50% owned are consolidated with a minority interest. Subsidiaries that are 50% owned or less, but 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 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 from the date of each acquisition for purchase business combinations.

CASH EQUIVALENTS, INVESTMENTS, AND RESTRICTED CASH AND INVESTMENTS

The Company considers all investment instruments purchased with an original maturity of three months or less to be cash equivalents. Investments other than restricted cash are primarily commercial paper and money market securities. Restricted cash is not considered a cash equivalent.

The current restricted cash and short-term investments balance includes commercial paper and money market securities, and is mainly composed of amounts deposited in restricted accounts from which the Company will source its 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.

The long-term restricted cash and investments balances are mainly composed of amounts deposited in restricted accounts from which the Company will fund the various projects under construction.

The Company's restricted 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 that holds the investments.

The Company's nuclear decommissioning trust funds and other marketable securities are classified as available for sale and are accounted for at fair value.

INVENTORY

Inventory is primarily composed of materials and supplies, coal stocks, gas in storage and fuel oil. Materials and supplies, coal stocks and fuel oil are at average cost and gas in storage is accounted for under the LIFO method.

PROPERTY, PLANT, 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.

F-28

Depreciation of the operating power plant costs, net of salvage value, is computed on the straight-line method over the estimated useful lives, between ten and thirty years. Depreciation of furniture, fixtures and equipment that 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.

Capitalized costs for gas reserves, other than costs of unevaluated exploration projects and projects awaiting development consent, are depleted using the units 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 estimated useful lives of the developed systems that range from three to fifteen years.

An allowance for the estimated annual decommissioning costs of the Quad Cities Generating Station ("Quad Cities Station") equal to the level of funding is included in depreciation expense. See Note 20 for additional information regarding decommissioning costs.

EXCESS OF COST OVER FAIR VALUE OF NET ASSETS ACQUIRED

Total acquisition costs in excess of the fair values assigned to the net assets acquired are amortized using the straight line method over a 25 to 40 year period.

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, based on discounted cash flows or various fair value models, whenever evidence exists that the carrying value is not recoverable.

CONTINGENT LIABILITIES

The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of the loss or impairment of an asset or the incurrence of a liability as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted.

REVENUE RECOGNITION

Revenues are recorded based upon services rendered and electricity, gas and steam delivered, distributed or supplied to the end of the period. Where there is an over recovery of distribution business revenues against the maximum regulated amount, revenues are deferred equivalent to the over recovered amount. The deferred amount is deducted from revenue and included in other liabilities. Where there is an under recovery, no anticipation of any potential future recovery is made.

The Company also records unbilled revenues representing the estimated amounts customers will be billed for services rendered between the meter reading dates in a particular month and the end of that month. Accrued unbilled revenues are included in accounts receivable on the consolidated balance sheets.

CAPITALIZATION OF INTEREST AND DEFERRED FINANCING COSTS

Prior to the commencement of operations, interest is capitalized on the costs of the construction projects and 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.

F-29

DEFERRED INCOME TAXES

The Company recognizes deferred tax assets and liabilities based on the difference between the financial statement and tax basis of assets and liabilities using estimated tax rates in effect for the year in which the differences are expected to reverse. The Company does not intend to repatriate earnings of foreign subsidiaries in the foreseeable future. As a result, deferred United States income taxes are not provided for retained earnings of international subsidiaries and corporate joint ventures unless the earnings are intended to be remitted.

FINANCIAL INSTRUMENTS

The Company currently utilizes or had previously utilized swap agreements and forward purchase agreements to manage market risks and reduce its exposure resulting from fluctuation in interest rates, foreign currency exchange rates and electric and gas prices. For interest rate swap agreements, the net cash amounts paid or received on the agreements are accrued and recognized as an adjustment to interest expense. Gains and losses related to gas forward contracts are deferred and included in the measurement of the related gas purchases. These instruments are either exchange traded or with counterparties of high credit quality; therefore, the risk of nonperformance by the counterparties is considered to be negligible.

FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS

For the Company's foreign operations whose functional currency is not the U.S. dollar, the assets and liabilities are translated into U.S. dollars at current exchange rates. Resulting translation adjustments are reflected as accumulated other comprehensive income (loss) in stockholders' equity. Revenues and expenses are translated at average exchange rates for the year.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency, except those transactions which operate as a hedge of an identifiable foreign currency commitment or as a hedge of a foreign currency investment position, are included in the results of operations as incurred.

RECLASSIFICATION

Certain amounts in the fiscal 2000 and 1999 consolidated financial statements and supporting note disclosures have been reclassified to conform to the fiscal 2001 presentation. Such reclassification did not impact previously reported net income or retained earnings.

USE OF ESTIMATES

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

ACCOUNTING FOR LONG-TERM POWER PURCHASE CONTRACT

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

Cooper capital improvement costs prior to 1997, including carrying costs, were deferred in accordance with then applicable rate regulation and are being amortized and recovered in rates over either a five-year period or the remaining term of the power purchase contract. Beginning July 11, 1997, the Iowa portion of capital improvement costs is recovered currently from customers and is expensed as incurred. For jurisdictions other than Iowa, MidAmerican Energy began charging Cooper capital improvement costs to expense as incurred in January 1997.

F-30

The fuel cost portion of the power purchase contract is included in cost of sales. All other costs MidAmerican Energy incurs in relation to its long-term power purchase contract with NPPD are included in operating expense.

ACCOUNTING PRINCIPLE CHANGE

Effective January 1, 2001, the Company has changed its accounting policy regarding major maintenance and repairs for nonregulated gas projects, nonregulated plant overhaul costs and geothermal well rework costs to the direct expense method from the former policy of monthly accruals based on long-term scheduled maintenance plans for the gas projects and deferral and amortization of plant overhaul costs and geothermal well rework costs over the estimated useful lives. The cumulative effect of the change in accounting principle was $4.6 million, net of taxes of $.7 million. If the Company had adopted the policy as of January 1, 2000, income before extraordinary item and cumulative effect of change in accounting principle would have been $6.3 million lower in 2000 on a proforma basis.

ACCOUNTING FOR DERIVATIVES

The Company is exposed to market risk, including changes in the market price of certain commodities and interest rates. To manage the price volatility relating to these exposures, the Company enters into various financial derivative instruments. Senior management provides the overall direction, structure, conduct and control of the Company's risk management activities, including the use of financial derivative instruments, authorization and communication of risk management policies and procedures, strategic hedging program guidelines, appropriate market and credit risk limits, and appropriate systems for recording, monitoring and reporting the results of transactional and risk management activities. The Company uses hedge accounting for derivative instruments pertaining to its natural gas purchasing, wholesale electricity activities, financing activities and preferred stock investing operations.

On January 1, 2001, the Company adopted Statement of Financial Accounting Standards Nos. 133 and 138 (SFAS Nos. 133/138) pertaining to the accounting for derivative instruments and hedging activities. SFAS Nos. 133/138 requires an entity to recognize all of its derivatives as either assets or liabilities in its statement of financial position and measure those instruments at fair value. If the conditions specified in SFAS Nos. 133/138 are met, those instruments may be designated as hedges. Changes in the value of hedge instruments would not impact earnings, except to the extent that the instrument is not perfectly effective as a hedge. At January 1, 2001, the Company recognized $44.9 million and $38.0 million of energy-related assets and liabilities, respectively, as being subject to fair value accounting pursuant to SFAS Nos. 133/138, all of which are accounted for as hedges. Additionally, on January 1, 2001, the Company's portfolio of preferred stock investments was transferred from the available for sale category to the trading category, as permitted by SFAS No.
133. Initial adoption of SFAS Nos. 133/138 did not have a material impact on the results of operations for the Company.

NEW ACCOUNTING PRONOUNCEMENTS

In July 2001, the FASB issued SFAS No. 141, "Business Combinations", and SFAS No. 142, "Goodwill and Other Intangible Assets" which establish accounting and reporting for business combinations. SFAS No. 141 requires all business combinations entered into subsequent to June 30, 2001, to be accounted for using the purchase method of accounting. SFAS No. 142 provides that goodwill and other intangible assets with indefinite lives will not be amortized but tested for impairment on an annual basis. SFAS No. 142 is effective for the Company beginning January 1, 2002. Under the current method of assessing goodwill for impairment, which uses an undiscounted cash flow approach, no material impairment existed at December 31, 2001. For 2002, the Company will begin to test goodwill for impairment under the new rules, applying a fair-value-based approach. The Company is in the process of quantifying the anticipated impact on its financial condition and results of operations of adopting the provisions of SFAS No. 142, which could be significant. The historical impact of not amortizing goodwill would have been to increase net income for the years ended December 31, 2001, 2000 and 1999 by $94.4 million, $92.4 million and $62.3 million, respectively. However, impairment reviews may result in future periodic write-downs.

F-31

In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations", which addresses the accounting for legal obligations associated with the retirement of tangible, long-lived assets, and the associated asset retirement costs. This pronouncement is effective for years beginning after June 15, 2002. The Company is evaluating the impact that adoption of this standard will have on its financial statements.

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", which addresses the financial accounting and reporting for the impairment or disposal of long-lived assets. This pronouncement is effective for years beginning after December 15, 2001. The Company is evaluating the impact that adoption of this standard will have on its financial statements, but does not believe it will have a material impact on its financial statements.

3. ACQUISITIONS/DISPOSITIONS

YORKSHIRE SWAP

On September 21, 2001, CE Electric UK Ltd., an indirect wholly owned subsidiary of the Company, and Innogy Holdings, plc executed an agreement to exchange Northern's electricity and gas supply and metering assets for Innogy's 94.75% interest in Yorkshire's electricity distribution business. Northern's supply business was initially valued at approximately $430 million ((pounds sterling)295 million), including working capital of approximately $53 million ((pounds sterling)37 million). 94.75% of Yorkshire's distribution business was initially valued at approximately $395 million ((pounds sterling)271 million), including working capital of approximately $48 million ((pounds sterling)33 million). The net cash received by Northern for the exchange was approximately $35 million ((pounds sterling)24 million). Working capital is subject to adjustment and is currently under review.

The disposition of Northern's supply business created a pre-tax non-recurring gain of $196.7 million and an after-tax gain of $10.8 million. Included in the carrying value of the Northern supply business was $504.4 million of goodwill allocated based on the relative fair values of the Northern supply business. In connection with the sale of the Northern supply business, management intends to sell the associated Northern retail business.

The Company paid $37.4 million, net of cash acquired of $362.8 million and transaction costs, for 94.75% of the Yorkshire electricity distribution business and related indebtedness. The acquisition has been accounted for as a purchase business combination. The results of operations for Yorkshire are included in the Company's results beginning September 21, 2001.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition (in millions).

TETON TRANSACTION

On October 24, 1999, the Company and an investor group comprised of Berkshire Hathaway, Walter Scott, Jr., and David L. Sokol, executed a definitive agreement and plan of merger whereby the investor

F-32

group would acquire all of the outstanding common stock of the Company for $35.05 per share in cash, representing a total purchase price of approximately $2.2 billion, including transaction costs (the "Teton Transaction"). The Teton Transaction closed on March 14, 2000 and Berkshire Hathaway invested approximately $1.24 billion in common stock and convertible preferred stock and approximately $455 million in 11% nontransferable trust preferred securities due March 14, 2010. Mr. Scott, Mr. Sokol and Gregory E. Abel, Chief Operating Officer of the Company, contributed cash and current securities of the Company having a value of approximately $310 million. The remaining purchase price was funded with the Company's cash. Berkshire Hathaway owns approximately 9.7% of the voting stock, Mr. Scott owns approximately 86% of the voting stock, Mr. Sokol owns approximately 3% of the voting stock and Mr. Abel owns approximately 1% of the voting stock.

The merger has been accounted for as a purchase business combination. The purchase price has been allocated to assets acquired and liabilities assumed. The Company recorded goodwill of approximately $1.2 billion that is being amortized using the straight-line method over a 40-year period.

The Company incurred approximately $7.6 million and $6.7 million of non-recurring costs in 2000 and 1999 respectively, related to the Teton Transaction, which were expensed.

Unaudited pro forma combined revenue, income before cumulative effect of change in accounting principle and net income of the Company and MEHC (Predecessor) for the years ended December 31, 2001 and 2000, as if the Yorkshire swap and the Teton Transaction had occurred at the beginning of each year after giving effect to pro forma adjustments related to the acquisitions, including the sale of the Northern Supply business and the issuance of the 11% trust preferred securities, were $4,401.0 million, $149.1 million and $144.5 million, respectively, compared to $4,084.0 million, $113.3 million and $113.3 million, respectively.

HOMESERVICES

On October 18, 1999, the Company closed on its initial public offering of 3.25 million shares of common stock of HomeServices at $15 per share. HomeServices sold 2.19 million newly issued shares and the Company, the selling stockholder, sold 1.06 million of its HomeServices shares in the offering. The offering reduced the Company's ownership in HomeServices to approximately 65%.

On April 14, 2000, the Company purchased 500,000 shares of HomeServices' common stock for $4.2 million, increasing the Company's ownership percentage to approximately 70%.

In October 2000, HomeServices repurchased 1.7 million shares of treasury stock for $17.9 million. This transaction increased the Company's ownership percentage to approximately 83%.

On August 27, 2001, the Company commenced a tender offer to purchase the remaining outstanding shares of common stock of HomeServices for a cash purchase price of $17 per share. On September 25, 2001, the Company announced that it had successfully completed the tender offer for all outstanding shares of the common stock of HomeServices for $29.3 million. As a result, the Company owns 100% of the outstanding HomeServices common stock, although options entitling employees to purchase HomeServices common stock remain outstanding.

ZINC RECOVERY PROJECT

The Company owns the rights to proprietary processes for the extraction of minerals from elements in solution in the geothermal brine and fluids utilized at its Imperial Valley plants. A pilot plant has successfully produced commercial quality zinc at the Company's Imperial Valley Projects.

CalEnergy Minerals LLC, an indirect wholly owned subsidiary of the Company, is constructing the Zinc Recovery Project which will recover zinc from the geothermal brine (the "Zinc Recovery Project"). Facilities are being installed near the Imperial Valley Project's sites to extract a zinc chloride solution from the geothermal brine through an ion exchange process. This solution will be transported to a central processing plant where zinc ingots will be produced through solvent extraction, electrowinning and casting processes. The Zinc Recovery Project is designed to have a capacity of approximately 30,000 metric tons per year and is scheduled to commence commercial operations in 2002. In September 1999, CalEnergy Minerals LLC entered into a sales agreement whereby all zinc produced by the Zinc Recovery Project will be sold to Cominco, Ltd. The initial term of the agreement expires in December 2005.

The Zinc Recovery Project was being constructed by Kvaerner U.S. Inc. ("Kvaerner") pursuant to a date certain, fixed-price, turnkey engineering, procure, construct and manage contract (the "Zinc Recovery Project EPC Contract"). On June 14, 2001, CalEnergy Minerals LLC issued notices of default, termination and demand for payment of damages to Kvaerner under the Zinc Recovery Project EPC Contract due to failure to meet performance obligations. As a result of Kvaerner's failure to pay monetary obligations under the Zinc Recovery Project EPC Contract, CalEnergy Minerals LLC drew $29.6 million under the EPC Contract Letter of Credit on July 20, 2001. CalEnergy Minerals LLC has entered into a time and materials reimbursable engineer, procure and construction management contract with AMEC E&C Services, Inc. to complete the Zinc Recovery Project.

On July 11, 2001, Kvaerner filed an Amended Demand For Arbitration against CalEnergy Minerals LLC characterizing the nature of the dispute as concerns regarding change orders and performance penalties. Kvaerner did not state the amount of its claim.

On August 7, 2001, CalEnergy Minerals LLC filed an Answering Statement and Counterclaim against Kvaerner. CalEnergy Minerals LLC denied all material allegations in Kvaerner's Amended Demand for

F-34

Arbitration, and asserted a counterclaim against Kvaerner for breach of contract and specific performance. CalEnergy Minerals LLC alleged that its total estimated damage for Kvaerner's breach of contract are in excess of approximately $60 million; however, CalEnergy Minerals LLC has offset approximately $42.5 million of these damages by exercising its rights under the EPC Contract to claim the retainage and by drawing on a letter of credit. Therefore, CalEnergy Minerals LLC has asked for a judgment in excess of approximately $20 million. The arbitration is scheduled for June 2002.

5. EQUITY INVESTMENT IN CE GENERATION

Due to the sale of 50% of its interests in CE Generation, the Company has accounted for CE Generation as an equity investment beginning March 3, 1999.

During 2001 and 2000, CalEnergy Capital Trust II redeemed 10,000 and 477,000 shares, respectively, of preferred securities at an aggregate cost of approximately $.4 million and $19.5 million, respectively.

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 Subordinated Debentures due February 25, 2012, September 1, 2027, and March 14, 2010, respectively, in outstanding aggregate principal amounts of approximately $155.5 million, $270 million and $454.8 million, 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.

Prior to the Teton Transaction, each Trust Security issued by CalEnergy Capital Trust II and III with a par value of $50 was convertible at the option of the holder at any time into shares of the Company's common stock based on the conversion rate. As a result of the Teton Transaction, in lieu of shares of the Company's common stock, holders of Trust Securities will receive $35.05 for each share of common stock it would have been entitled to receive on conversion.

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.

F-42

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. SUBSIDIARY-OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES OF SUBSIDIARY TRUST

In December 1996, MidAmerican Energy Financing I, a wholly owned statutory business trust of MidAmerican Energy, issued 4,000,000 shares of 7.98% Series MidAmerican Energy-obligated mandatorily redeemable preferred securities. The sole assets of MidAmerican Energy Financing are $103.1 million of MidAmerican Energy 7.98% Series A Debentures due 2045 (the "Debentures"). There is a full and unconditional guarantee by MidAmerican Energy of MidAmerican Energy Financing's obligations under the preferred securities. MidAmerican Energy 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 Energy may not declare or pay any dividend or other distribution on, or redeem or purchase, any of its capital stock.

If the Debentures, or a portion thereof, are redeemed, MidAmerican Energy Financing must redeem a like amount of the preferred securities. If a termination of MidAmerican Energy Financing occurs, MidAmerican Energy Financing 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 a determination is made, the holders of the preferred securities will be entitled to receive, out of the assets of MidAmerican Energy Financing after satisfaction of its liabilities, a liquidation amount of $25 for each preferred security held plus accrued and unpaid distributions. See Note 21.

In connection with the Teton Transaction, the Company issued 34.6 million shares of no par, zero coupon convertible preferred stock valued at $1,211.4 million. Each share of preferred stock is convertible at the option of the holder into one share of the Company's common stock subject to certain adjustments as described in the Company's Amended and Restated Articles of Incorporation

13. STOCK OPTIONS

The Company had various 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 allowed options to be granted at 85% of their fair market value of the common stock at the date of grant. Generally, options were issued at 100% of fair market value of the common stock at the date of grant. Options granted under the 1996 plan became exercisable over a period of two to five years and expired if not exercised within ten years from the date of grant or, in some instances, a lesser term.

As a result of the Teton Transaction, the majority of the options were cashed out at $35.05 per share. The remaining options of 2,145,000 were reissued under the new MidAmerican Energy Holdings Company and an additional 703,329 options were issued. The old options are fully vested and the additional options vest monthly over three years. The options are exercisable until the end of the term on March 14, 2008 at exercise prices ranging from $15.94 to $35.05 per share.

14. 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

F-43

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 that the Company could realize in a current transaction.

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

Short-term debt -- Due to the short-term nature of the short-term debt, the fair value approximates the carrying value.

Debt instruments -- The fair value of all debt issues listed on exchanges has been estimated based on the quoted market prices. The Company is unable to estimate a fair value for the Philippine term loans as there are no quoted market prices available.

Other financial instruments -- All other financial instruments of a material nature are short-term and the fair value approximates the carrying amount.

INTEREST RATE RISK

At December 31, 2001, the Company had fixed-rate long-term debt, Company-obligated mandatorily redeemable preferred securities of subsidiary trusts, and subsidiary-obligated mandatorily redeemable preferred securities of subsidiary trusts of $7,678.0 million in principal amount and having a fair value of $7,808.2 million. These instruments are fixed-rate and therefore do not expose the Company to the risk of earnings loss due to changes in market interest rates. However, the fair value of these instruments would decrease by approximately $355.7 million if interest rates were to increase by 10% from their levels

F-44

at December 31, 2001. In general, such a decrease in fair value would impact earnings and cash flows only if the Company were to reacquire all or a portion of these instruments prior to their maturity.

At December 31, 2001, the Company had floating-rate obligations of $281.4 million that expose the Company to the risk of increased interest expense in the event of increases in short-term interest rates. These obligations are not hedged. If the floating rates were to increase by 10% from December 31, 2001 levels, the Company's consolidated interest expense for unhedged floating-rate obligations would increase by approximately $75,000 each month in which such increase continued based upon December 31, 2001 principal balances.

15. NON-RECURRING ITEMS

TEESSIDE

In December 2001, the Company recorded a non-recurring charge of $20.7 million representing an asset valuation impairment charge under SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets," relating to the Company's 15.4% interest in Teesside Power Ltd. ("Teesside"). Teesside owns and operates an 1,875 MW combined cycle gas-fired power plant. Enron Corp. ("Enron"), through its subsidiaries, owned a 42.5% interest, operated the plant, and purchased 668MW of capacity. Enron's subsidiary, who owns and operates Teesside, is now in administration and administrators have been appointed to run its business and are attempting to find a buyer. As a result of Enron's subsidiary being in administration, Teesside is in discussion with its lenders over restructuring of the (pounds sterling)650 million debt still outstanding. It is anticipated that there will be no further dividends arising from the investment in Teesside and subsequently, the Company has determined the investment in Teesside to be of negligible value.

TELEPHONE FLAT SALE

On October 16, 2001, the Company closed on a transaction that transferred all properties and rights of the Telephone Flat Project, a geothermal development project in northern California to Calpine Corp. The Company recorded a pre-tax gain of $20.7 million and an after-tax gain of $12.2 million on the sale of the Telephone Flat Project.

WESTERN STATES SALE

On June 30, 2001, the Company closed on a transaction in which the Company sold Western States Geothermal, an indirect wholly owned subsidiary of the Company, to Ormat. The Company recorded a pre-tax gain of $9.8 million and an after-tax gain of $6.4 million on the sale of Western States Geothermal.

QUALIFIED FACILITIES DISPOSITIONS

On February 26, 1999, the Company closed the sale of all of its indirect ownership interests in the Coso Joint Ventures ("Coso") to Caithness Energy LLC ("Caithness") for $205 million in cash. On March 3, 1999, the Company closed the sale of 50% of its ownership interests in CE Generation to an affiliate of El Paso Energy Corporation for an aggregate consideration of approximately $245 million in cash, $6.5 million in contingent payments and $23.5 million in equity commitments. The sales of the qualified facilities resulted in a net non-recurring pre-tax gain of $20.2 million and an after-tax gain of approximately $12.4 million.

MCLEOD

On May 18, 1999, the Company announced the sale of approximately 6.74 million shares of McLeodUSA ("McLeod") Class A common stock, through a secondary offering by McLeod, at $55.625 per share. Proceeds from the sale were approximately $375 million, with a resulting pre-tax gain to the Company of approximately $78.2 million, and an after-tax gain of approximately $47.1 million.

INDONESIA

On December 2, 1994, former subsidiaries of the Company, Himpurna California Energy Ltd. ("HCE") and Patuha Power, Ltd. ("PPL", together with HCE, the "Indonesian Subsidiaries") executed separate joint operation contracts for the development of geothermal steam fields and geothermal power facilities located in Central Java in Indonesia.

In 1997 and 1998 a series of Indonesian government decrees and other actions created significant uncertainty as to whether the Indonesian government would honor their contractual obligations to the Indonesian Subsidiaries. In 1997, the Company recorded a non-recurring charge of $87 million representing an asset valuation impairment charge under SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets," relating to the Company's assets in Indonesia. The charge of $87 million represented the amount by which the carrying amount of such assets exceeded the estimated fair value of the assets determined by discounting the expected future net cash flows of the Indonesia projects.

The Company carried political risk insurance on its investment in HCE and PPL through OPIC, an agency of the U.S. Government, as well as through private market insurers. On November 18, 1999, the Company transferred the Indonesian Subsidiaries to OPIC and received payment from OPIC and the private market insurers totaling $290 million under its political risk insurance policies, reflecting the return of its equity investment less policy deductibles. Due primarily to the timing of the receipt of proceeds, the Company recorded a pre-tax gain of approximately $40.3 million on the insurance proceeds and an additional tax benefit of $17.7 million for an after-tax gain of $58.0 million.

On September 13, 2001, the Company transferred shares of Bali Energy Ltd., an indirect wholly owned Indonesian subsidiary of the Company, to PT Tenaga Burni Bali. The Company recorded a pre-tax gain of $10.4 million and an after-tax gain of $6.5 million on the transfer of the shares.

16. ACCOUNTING FOR DERIVATIVES

INTEREST RATE RISK

MidAmerican Energy has entered into a two-year, $162 million fixed-to-floating interest rate swap agreement in conjunction with its $162 million, 7.375% series of medium-term notes due August 1, 2002. The floating rate of the swap is based on a three-month LIBOR rate and the effective interest rate after the swap was 4.46% in 2001. As of December 31, 2001, the fair value of this swap was $9.1 million.

CE Electric UK Funding entered into certain currency rate swap agreements for the CE Electric UK Funding Company Senior Notes with two large multi-national financial institutions. The swap agreements effectively convert the U.S. dollar fixed interest rate to a fixed rate in Sterling. For the $125 million 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 million 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 at December 31, 2001 is approximately $44.8 million based on quotes from the counterparty to these instruments and represents the estimated amount that the Company would expect to receive if these agreements were terminated. It is the Company's intention to hold these swap agreements to maturity.

Yorkshire entered into certain currency rate swap agreements for the Trust Securities and the Yankee Bonds with five large multi-national financial institutions. The swap agreements effectively convert the U.S. dollar fixed interest rate to a fixed rate in Sterling. For the $255 million of Trust Securities, the agreements extend until June 30, 2008 and convert the U.S. dollar interest rate to a fixed Sterling rate ranging from 9.4758% to 9.715%. For the $300 million of Yankee Bonds, the agreements extend until February 25, 2008 and convert the U.S. dollar interest rate to a fixed Sterling rate ranging from 7.3175% to 7.345%. The estimated fair value of these swap agreements at December 31, 2001 is approximately $8.4 million based on quotes from the counterparty to these instruments and represents the estimated amount that the Company would expect to receive if these agreements were terminated. It is the Company's intention to hold these swap agreements to maturity.

A decrease of 10% in the December 31, 2001 rate of exchange of Sterling to dollars would increase the amount received if these swap agreements were terminated by approximately $106.4 million.

ENERGY COMMODITY PRICE RISK

Under the current regulatory framework, MidAmerican Energy is allowed to recover in revenues the cost of gas sold from all of its regulated gas customers through a purchased gas adjustment clause. Because the majority of MidAmerican Energy's firm natural gas supply contracts contain pricing provisions based on a daily or monthly market index, MidAmerican Energy's regulated gas customers, although ensured of the availability of gas supplies, retain the risk associated with market price volatility.

MidAmerican Energy enters into natural gas futures and swap agreements to mitigate a portion of the market risk retained by its regulated gas customers through the purchased gas adjustment clause. These financial derivative activities are recorded as hedge accounting transactions, with net amounts exchanged or accrued under swap agreements and realized gains or loses on futures contracts included in the cost of gas sold and recovered in revenues from regulated gas customers.

MidAmerican Energy also derives revenues from nonregulated sales of natural gas. Pricing provisions are individually negotiated with these customers and may include fixed prices or prices based on a daily or monthly market index. MidAmerican Energy enters into natural gas futures and swap agreements to offset the financial impact of variations in natural gas commodity prices for physical delivery to nonregulated customers. These financial derivative activities are also recorded as hedge accounting transactions.

MidAmerican Energy uses natural gas derivative instruments for trading purposes pursuant to EITF 98-10 under strict value-at-risk guidelines outlined by senior management. Derivative instruments held for trading purposes are recorded at fair value and any unrealized gains or losses are reported in earnings. Trading revenues and costs are reported gross on the consolidated statements of operations.

MidAmerican Energy is exposed to variations in the price of fuel for generation and the price of purchased power in its Iowa jurisdiction comprising 89% of 2001 electric operating revenues. Fuel price risk is mitigated through forward contracts. Under typical operating conditions, MidAmerican Energy has sufficient generation to supply its retail electric needs. A loss of such generation at a time of high market prices could subject MidAmerican Energy to losses on its energy sales. MidAmerican Energy uses electricity forward contracts to hedge anticipated sales of wholesale electric power.

MidAmerican Energy and its customers are exposed to the effect of variations in weather conditions on sales and purchased, respectively, of electricity and natural gas. For the 2001-2002 heating season, MidAmerican Energy entered into several degree-day swaps to offset a portion of the financial impact of those variations on MidAmerican Energy and its customers.

MidAmerican Energy had the following financial derivative instruments for its natural gas and electric operations as of December 31:

A $1.00 decrease in underlying natural gas prices would decrease unrealized gains on the futures contracts held at December 31, 2001, by approximately $0.6 million and would decrease unrealized losses on the above swap contracts by approximately $7.0 million. A $5.00 increase in underlying electricity prices would decrease unrealized gains on the forward contracts held at December 31, 2001, by approximately $3.6 million. The weighted average maturity for all derivative instruments used for hedging purposes is under one year.

Unrealized gains and losses on cash flow hedges of future transactions are recorded in other comprehensive income. Only hedges that are highly effective in offsetting the risk of variability in future cash flows are accounted for in this manner. Future transactions include purchases of gas for resale to regulated and nonregulated customers, purchases of gas for storage, and purchases and sales of wholesale electric energy. When the associated hedged future transaction occurs or if a hedging relationship is no longer appropriate, the unrealized gains and losses are reversed from other comprehensive income and recognized in net income. Realized gains on cash flow hedges are recorded in either cost of sales or operating revenues, depending upon the nature of the physical transaction being hedged.

For 2001, a net loss of $408,000 and a net gain of $36,000, representing the ineffectiveness of cash flow hedges, are reflected in cost of sales. During the twelve months beginning January 1, 2002, it is anticipated that $3.4 million of the $3.5 million after-tax, net unrealized gains on cash flow hedges presently recorded as accumulated other comprehensive income will be realized and recorded in earnings. MidAmerican Energy has hedged a portion of its exposure to the variability of cash flows for future transactions through December 2003.

Unrealized gains and losses on fair value hedges are recognized in income as either operating revenues or cost of sales depending upon the nature of the item being hedged. Purchase and sales commitments hedged by fair value hedges are recorded at fair value, with the changes in values also recognized in income and substantially offsetting the impact of the hedges on earnings. For 2001, a net pre-tax gain of $18,000, representing the ineffectiveness of fair value hedges, is included in operating revenues.

17. SECURITIZATION OF ACCOUNTS RECEIVABLE

In December 1998, CE Electric UK Funding entered into a revolving receivable purchase agreement with Kitty Hawk Funding Corporation ("Kitty Hawk"), an unaffiliated special purpose entity established to purchase accounts receivable. In October 2000, the facility was transferred to Mont Blanc Capital Corp, administered by ING Barings, which allowed CE Electric UK Funding to sell all of its rights, title and interest in the majority of its billed electricity accounts receivable and to borrow against its unbilled electricity accounts receivable. In March 1999, CE Electric UK Funding received $161 million in cash associated with the agreement. In connection with the Northern Supply/Yorkshire swap on September 21, 2001, CE Electric UK Funding repaid the outstanding balance of this purchase agreement and ended their arrangement with Mont Blanc Capital Corp. CE Electric UK Funding does not have any amounts outstanding at December 31, 2001.

In 1997, MidAmerican Energy entered into a revolving agreement, which expires in October 2002, to sell all of its right, title and interest in the majority of its billed accounts receivable to MidAmerican Energy Funding Corporation, a special purpose entity established to purchase accounts receivable from MidAmerican Energy. MidAmerican Energy Funding Corporation in turn sells receivable interests to outside investors. In consideration of the sale, MidAmerican Energy received cash and a subordinated note, bearing interest at 8%, from MidAmerican Energy Funding Corporation. As of December 31, 2001, the revolving cash balance was $44 million, down $26 million from December 31, 2000, and the amount outstanding under the subordinated note was $28.7 million. The agreement is structured as a true sale under which the creditors or MidAmerican Energy Funding Corporation will be entitled to be satisfied out of the assets of MidAmerican Energy Funding Corporation prior to any value being returned to MidAmerican Energy or its creditors. Therefore, the accounts receivable sold are not reflected on the consolidated balance sheets. At December 31, 2001, $71.5 million of accounts receivable, net of reserves, was sold under the agreement.

18. REGULATORY MATTERS

CE ELECTRIC UK FUNDING

Most revenue of each Distribution License Holder ("DLH") is controlled by a distribution price control formula. The current formula requires that regulated distribution income per unit is increased or decreased each year by RPI-Xd where the Retail Price Index ("RPI") reflects the average of the 12-month inflation rates recorded for each month in the previous July to December period. The distribution price control formula also reflects an adjustment factor ("Xd") which was established by the regulatory body, the Office of Gas and Electricity Markets ("Ofgem"), at the last price control review (and continues to be set) at 3%. The formula also takes account of the changes in system electrical losses, the number of

F-51

customers connected and the voltage at which customers receive the units of electricity distributed. This formula determines the maximum average price per unit of electricity distributed (in pence per kilowatt hour) which a DLH is entitled to charge. The distribution price control formula permits DLHs to receive 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 DLH from year to year. It is a control on revenue that operates independently of most of the DLH's costs. During the lifetime of the price control, additional cost savings therefore contribute directly to profit.

MIDAMERICAN ENERGY

In 1997, pursuant to a rate proceeding before the Iowa Utilities Board ("IUB"), MidAmerican Energy, the Office of Consumer Advocate and other parties entered into a pricing plan settlement agreement establishing MidAmerican Energy's Iowa retail electric rates. That settlement agreement expired on December 31, 2000.

On March 14, 2001, the Office of the Consumer Advocate filed a petition with the IUB to reduce Iowa retail electric rates by approximately $77 million annually. On June 11, 2001, MidAmerican Energy responded to that petition by filing a request with the IUB to increase MidAmerican Energy's Iowa retail electric rates by $51 million annually. On December 21, 2001, the IUB approved a settlement agreement that freezes the rates in effect on December 31, 2000, through December 31, 2005, and, with modifications, reinstates the revenue sharing provisions of the 1997 pricing plan settlement agreement. Under the 2001 settlement agreement, an amount equal to 50% of revenues associated with returns on equity between 12% and 14%, and 83.33% of revenues associated with returns on equity above 14%, in each year will be recorded as a regulatory liability to be used to offset a portion of the cost of future generating plant investments. An amount equal to the regulatory liability will be recorded as depreciation expense. As of December 31, 2001, MidAmerican Energy has recorded a $47.1 million regulatory liability that is reflected in other long-term accrued liabilities on the consolidated balance sheet.

Under an Illinois restructuring law enacted in 1997, a sharing mechanism is in place for MidAmerican Energy's Illinois regulated retail electric operations whereby earnings above a computed threshold will be shared equally between customers and shareholders. A two-year average return on common equity greater than a two-year average benchmark will trigger an equal sharing of earnings on the excess. MidAmerican Energy's computed level of return on common equity is based on a rolling two-year average of the 30-year Treasury bond rates plus a premium of 5.50% for 1998 and 1999 and a premium of 8.5% for 200 through 2004. The two-year average above which sharing must occur for 2001 was 14.33%. The law allows MidAmerican Energy to mitigate the sharing of earnings above the threshold return on common equity through accelerated recovery of regulatory assets.

On September 21, 2001, MidAmerican Energy filed a petition with the South Dakota Public Utilities Commission ("SDPUC") to increase its South Dakota natural gas rates. On February 20, 2002, the SDPUC approved a settlement agreement allowing increased rates of $3.1 million annually.

On October 19, 2001, MidAmerican Energy filed a petition with the Illinois Commerce Commission to increase its Illinois natural gas rates by $3.2 million annually. A final decision on the petition is required within eleven months of the date of filing.

On March 15, 2002, MidAmerican Energy made a filing with the IUB requesting an increase in rates of approximately $26.6 million for its Iowa retail natural gas customers. As part of the filing, MidAmerican Energy requested an interim rate increase of approximately $20.4 million annually. The IUB may adjust the requested interim amount and delay its implementation for up to ninety days. MidAmerican Energy expects the final rates, which may differ from the requested amount, to be implemented in the fourth quarter.

19. PENSION COMMITMENTS

UNITED KINGDOM OPERATIONS

CE Electric UK Funding 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.

F-52

The actuarial computation for December 31, 2001, 2000 and 1999 assumed interest rates of 5.75%, 6.0% and 6.0% respectively, an expected return on plan assets of 7.0%, 6.5% and 6.5%, respectively, and annual compensation increases of 2.5%, 3.0% and 3.0%, 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.

As a result of the distribution price reviews in 1999, CE Electric UK Funding implemented a review of staffing requirements primarily in its distribution business. Following discussions with the trade unions, CE Electric UK Funding put in place a workforce reduction program. In 1999, the Company recorded a non-recurring pre-tax loss of approximately $47.7 million that included a pension curtailment of $38.3 million. In 2000, the pension curtailment related to this workforce reduction program was $6.6 million. The curtailment loss in 2001 of $7.1 million is a result of the Northern Supply/Yorkshire swap.

DOMESTIC OPERATIONS

The Company has primarily noncontributory cash balance defined benefit pension plans covering substantially all domestic employees. Benefit obligations 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. The Company has been allowed to recover pension costs related to its employees in rates.

MidAmerican Energy currently provides certain postretirement health care and life insurance benefits for retired employees. Under the plans, substantially all of MidAmerican Energy's employees may become eligible for these benefits if they reach retirement age while working for MidAmerican Energy. However, MidAmerican Energy retains the right to change these benefits anytime at its discretion. MidAmerican Energy expenses postretirement benefit costs on an accrual basis and includes provisions for such costs in rates.

In 1999, the noncontributory cash balance defined benefit pension plans, the noncontributory, nonqualified supplemental executive retirement plan, and the postretirement plans were amended to include participants from the Company. Prior to the amendment, these plans included only employees and participants of MidAmerican Energy. This inclusion increased the benefit obligation by $14.8 million for the pension and nonqualified supplemental retirement plans and $2.8 million for the postretirement plans.

MidAmerican Energy also maintains noncontributory, nonqualified supplemental executive retirement plans for active and retired participants.

During 2000, MidAmerican Energy adopted a market-related valuation of its pension assets for purposes of calculating net periodic pension costs. This change conforms MidAmerican Energy's accounting practices for pension costs to that of the Company. Net periodic pension, supplemental retirement and postretirement benefit costs included the following components for the Company:

The pension plan assets are in external trusts and are comprised of corporate equity securities, United States government debt, corporate bonds and insurance contracts. The postretirement benefit plans assets are in external trusts and are comprised primarily of corporate equity securities, corporate bonds, money market investment accounts and municipal bonds.

Although the supplemental executive retirement plans had no plan assets as of December 31, 2001, MidAmerican Energy has Rabbi trusts which hold corporate-owned life insurance and other investments to provide funding for the future cash requirements. Because these plans are nonqualified, the fair value of these assets is not included in the following table. The fair value of the Rabbi trust investments was $50.4 million and $44.7 million at December 31, 2001 and 2000, respectively.

During 1999 certain participants in the supplemental executive retirement plan left MidAmerican Energy reducing the future service of active employees by 28%. As a result, a curtailment loss of $5.3 million was recognized by the Company in 1999. Additionally, termination benefits provided to the participants, totaling $3.5 million, were expensed by MidAmerican Energy during 1999.

The projected benefit obligation and accumulated benefit obligation for the supplemental executive retirement plans were $91.2 million and $88.2 million, respectively, as of December 31, 2001 and $82.7 million and $77.5 million, respectively, as of December 31, 2000.

The following table presents a reconciliation of the beginning and ending balances of the benefit obligation, fair value of plan assets and the funded status of MidAmerican Energy's plans to the net amounts recognized in the consolidated balance sheet as of December 31 (dollars in thousands):

For purposes of calculating the postretirement benefit obligation, it is assumed health care costs for all covered individuals will increase by 11.25% in 2002 and that the rate of increase thereafter will decrease to an ultimate rate of 5.25% by the year 2006.

If the assumed health care trend rates used to measure the expected cost of benefits covered by the plans were increased by 1.0%, the total service and interest cost for 2001 would increase by $3.0 million, and the postretirement benefit obligation at December 31, 2001, would increase by $30.6 million. If the assumed health care trend rates were to decrease by 1.0%, the total service and interest cost for 2001 would decrease by $2.3 million and the postretirement benefit obligation at December 31, 2001, would decrease by $24.2 million.

20. COMMITMENTS AND CONTINGENCIES

A. FINANCIAL CONDITION OF EDISON

Southern California Edison Company ("Edison"), a wholly-owned subsidiary of Edison International, is a public utility primarily engaged in the business of supplying electric energy to retail customers in Central and Southern California, excluding Los Angeles. The Company is aware that there have been public announcements that Edison's financial condition has deteriorated as a result of reduced liquidity. Following Edison's recent financing, Edison's senior unsecured debt obligations were upgraded to Ba3 by Moody's and BB by S&P.

Edison failed to pay approximately $119 million due under the power purchase agreement with CE Generation affiliates for power delivered in November and December 2000 and January, February and March 2001, although the Power Purchase Agreements provide for billing and payment on a schedule where payments would have normally been received in early January, February, March, April and May 2001.

On February 21, 2001, the Imperial Valley Projects (excluding the Salton Sea V and Turbo Projects) filed a lawsuit against Edison in California's Imperial County Superior Court seeking a court order requiring Edison to make the required payments under the Power Purchase Agreements. The lawsuit also requested, among other things, that the court order permit the Imperial Valley Projects (excluding the Salton Sea V and Turbo Projects) to suspend deliveries of power to Edison and to permit the Imperial Valley Projects to sell such power to other purchasers in California.

On March 22, 2001, the Imperial County Superior Court granted the Imperial Valley Projects' (excluding the Salton Sea V and Turbo Projects) Motion for Summary Adjudication and a Declaratory Judgment ordering that: 1) under the Power Purchase Agreements, the Imperial Valley Projects (excluding the Salton Sea V and Turbo Projects) have the right to temporarily suspend deliveries of capacity and energy to Edison, 2) such Imperial Valley Projects (excluding the Salton Sea V and Turbo Projects) are entitled to resell the energy and capacity to other purchasers and 3) the interim suspension of deliveries to Edison shall not in any respect result in the modifications or termination of the Power Purchase Agreements, and the Power Purchase Agreements shall in all respects continue in full force and effect other than the temporary suspension of deliveries to Edison.

As a result of the March 22, 2001 Declaratory Judgment, the Imperial Valley Projects (excluding the Salton Sea V and Turbo Projects) suspended deliveries of energy to Edison and entered into a transaction agreement with El Paso Merchant Energy, L.P. ("EPME") in which the Imperial Valley Projects' (excluding the Salton Sea V and Turbo Projects) available power was sold to EPME based on percentages of the Dow Jones SP-15 Index. On June 18, 2001 the Superior Court prospectively vacated its order authorizing the Imperial Valley Projects' (excluding the Salton Sea V and Turbo Projects) right to resell power pursuant to the Declaratory Judgment.

On June 20, 2001, the Imperial Valley Projects (excluding Salton Sea Unit V and CE Turbo) entered into Agreements Addressing Renewable Energy Pricing and Payment Issues with Edison ("Settlement Agreements") and, as a result, resumed power sales to Edison on June 22, 2001. The Settlement Agreements required that Edison make an initial payment to repay the past due balances under the Power Purchase Agreements (the "stipulated amounts"). The initial payment of approximately $11.6 million, which represented 10% of the stipulated amounts, was received June 22, 2001. On October 2, 2001, the California Public Utilities Commission announced an agreement with Edison that allowed Edison to recover in retail electric rates its past due obligations. On November 30, 2001, the Settlement Agreements were amended to reflect when Edison would be required to make the final payment on past due amounts. On March 1, 2002, Edison obtained $1.8 billion in secured financing that, when combined with cash on hand, enabled Edison to pay off its past due debts. The final payment of approximately $104.6 million, representing the remaining stipulated amounts, was received March 1, 2002. In addition to these payments, Edison was required to make monthly interest payments calculated at a rate of 7% per annum on the outstanding stipulated amounts. The amended Settlement Agreements provide a revised energy pricing structure, whereby Edison elects to pay the Imperial Valley Projects a fixed energy price in lieu

F-57

of the Commission-approved Avoided Cost of Energy Methodology under the Power Purchase Agreements. The fixed energy price is 3.25 cents/kWh from December 2001 through April 30, 2002 and 5.37 cents/kWh commencing May 1, 2002 for a five year period. Following the five year period, the energy payments revert back to the Commission-approved Avoided Cost of Energy Methodology under the Power Purchase Agreements. Estimates of Edison's future Avoided Cost of Energy vary substantially from year to year.

As a result of Edison's failure to make the payments due under the Power Purchase Agreements and the downgrades of Edison's credit rating, Moody's downgraded the ratings for the Salton Sea Funding Corporation (the "Funding Corporation") Securities to Caa2 (negative outlook) and S&P downgraded the ratings for the Funding Corporation Securities to BBB- and placed the Securities on "credit watch negative." Moody's downgraded the ratings for the CE Generation Securities to B1 from Baa3 (review for possible downgrade). Following the execution of the Settlement Agreements, Moody's placed the Salton Sea Funding and CE Generation securities on "credit watch positive." The Funding Corporation Securities are currently rated Ba3 by Moody's and BBB- by S&P. CE Generation Securities are currently Ba2 by Moody's and BBB- by S&P.

B. CASECNAN

The Casecnan Project was initially 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, the Company terminated the Hanbo Contract due to defaults by Hanbo and HECC including the insolvency of both companies. On the same date, the Company entered into a new fixed-price, date certain, 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 Impresa Pizzarotti & C. Spa., working together with Siemens A.G., Sulzer Hydro Ltd., Black & Veatch and Colenco Power Engineering Ltd. (collectively, the "Contractor").

On November 20, 1999, the Replacement Contract was amended to extend the Guaranteed Substantial Completion Date for the Casecnan Project to March 31, 2001. This amendment was approved by the lender's independent engineer under the Casecnan Indenture.

On February 12, 2001, the Contractor filed a Request for Arbitration with the International Chamber of Commerce seeking an extension of the Guaranteed Substantial Completion Date by up to 153 days through August 31, 2001 resulting from various alleged force majeure events. In a March 20, 2001 Supplement to Request for Arbitration, the Contractor also seeks compensation for alleged additional costs of approximately $4 million it incurred from the claimed force majeure events to the extent it is unable to recover from its insurer. On April 20, 2001, the Contractor filed a further supplement seeking an additional approximately $62 million in damages for the alleged force majeure event (and geologic conditions) related to the collapse of the surge shaft. The Contractor alleged that the circumstances surrounding the placing of the Casecnan Project into commercial operation on December 11, 2001 amounted to a termination of the Replacement Contract and filed a claim for unspecified quantum meruit damages. CE Casecnan believes such allegations and claims are without merit and is vigorously defending the Contractor's claims. The arbitration is being conducted applying New York law and pursuant to the rules of the International Chamber of Commerce.

On June 25, 2001, the arbitration tribunal temporarily enjoined CE Casecnan from making calls on the demand guaranty posted by Banca di Roma in support of the Contractor's obligations to CE Casecnan for delay liquidated damages. Hearings on the force majeure claims were held in London from July 2 to 14, 2001, and hearings on the Contractor's April 20, 2001 supplement were held in London from September 24 to October 3, 2001. Further hearings were held from January 2 to February 1, 2002 and additional hearings were held from March 14 to 19, 2002.

As of December 31, 2001 the Company has received approximately $6.0 million of liquidated damages from demands made or the demand guarantees posted by Commerzbank on behalf of the Contractor.

F-58

Although the outcome of the arbitration is difficult to assess, CE Casecnan believes it will prevail and receive substantial additional liquidated damages in the arbitration.

Under the Project Agreement, if NIA is able to accept delivery of water into the Pantabangan Reservoir and NPC has completed the Project's related transmission line, the Company is liable to pay NIA $5,500 per day for each day of delay in completion of the Casecnan Project beyond July 27, 2000, increasing to $13,500 per day for each day of delay in completion beyond November 27, 2000. NIA completed the installation of the transmission line on August 13, 2001. Accordingly, the Company accrued $1.6 million liquidated damages payable to NIA for 120 days of delay.

The Company's ability to make payments on any of its existing and future obligations is dependent on NIA's and the Republic of the Philippines' performance of their obligations under the Project Agreement and the Performance Undertaking, respectively. Except to the extent expressly provided for in the Shareholder Support Letters, no shareholders, partners or affiliates of the Company, including MidAmerican, and no directors, officers or employees of the Company will guarantee or be in any way liable for payment of the Company's obligations. As a result, payment of the Company's obligations depends upon the availability of sufficient revenues from the Company's business after the payment of operating expenses.

C. DECOMMISSIONING COSTS

Expected decommissioning costs for Quad Cities Station and Cooper have been developed based on site-specific decommissioning studies that include decontamination, dismantling, site restoration, dry fuel storage cost and assumed shutdown dates. In Illinois, Cooper nuclear decommissioning costs are recovered through a rate rider on customer billings that permits annual adjustments. Quad Cities Station and Cooper decommissioning costs are reflected as base rates in Iowa tariffs.

MidAmerican Energy's share of expected decommissioning costs for Quad Cities Station, in 2001 dollars, is $278 million. MidAmerican Energy has established external trusts for the investment of funds for decommissioning the Quad Cities Station. The total accrued balance as of December 31, 2001, was $158.3 million and is included in other long-term accrued liabilities, and a like amount is reflected in Investments and represents the fair value of the assets held in the trusts.

MidAmerican Energy's depreciation expense included costs for Quad Cities Station nuclear decommissioning of $8.3 million, $8.3 million, and $10.4 million for 2001, 2000 and 1999, respectively. The provision charged to depreciation expense is equal to the funding that is being collected in rates. The decommissioning funding component of MidAmerican Energy's Illinois and Iowa tariffs assumes decommissioning costs, related to the Quad Cities Station, will escalate at an annual rate of 4.5% and the assumed annual return on funds in the trust is 6.9%. Realized income (loss), net of investment fees, on the assets in the trust fund was $(0.6) million, $1.9 million and $1.9 million for 2001, 2000 and 1999, respectively.

MidAmerican Energy's contribution toward payment of Cooper's projected decommissioning costs have been based on the NPPD decommissioning funding plan for Cooper. Total expected decommissioning costs for Cooper, in 2001 dollars, are $577 million. For purposes of developing a decommissioning funding plan for Cooper, the 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, 2001, total funds set aside in the internal and external accounts for Cooper decommissioning that are maintained by the NPPD were $291.3 million. In addition, the funding plan for Cooper also assumes various funds and reserves currently held to satisfy the NPPD bond resolution requirements will be available for plant decommissioning, which is to begin with the assumed plant shutdown in September 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. Earnings from the internal account and external trust fund, which are recognized by the NPPD as the owner of the plant, are tax exempt and serve to reduce future funding requirements.

F-59

Beginning in December 2000, MidAmerican Energy ceased contributing to the accounts maintained by NPPD and began contributing funds to a separate MidAmerican Energy bank account based on the NPPD decommissioning funding plan for Cooper. A liability equal to the amount of funds contributed, plus the earnings on those funds, is reflected in other long-term accrued liabilities on the consolidated balance sheets. MidAmerican Energy records expense equal to the funds contributed to the separate account plus investment fees paid to the NPPD for funds in the accounts they maintain. MidAmerican Energy's expense for Cooper decommissioning was $11.6 million, $11.5 million and $11.3 million for the years 2001, 2000 and 1999, respectively, and is included in other operating expenses.

MidAmerican Energy is currently involved in litigation with NPPD in part related to the determination of MidAmerican Energy's obligation, if any, for costs of decommissioning Cooper. Refer to Note (20)(E) for a discussion of the proceedings.

D. NUCLEAR INSURANCE

MidAmerican Energy maintains financial protection against catastrophic loss associated with its interest in Quad Cities Station and Cooper through a combination of insurance purchased by NPPD (the owner and operator of Cooper) and Exelon Generation Company, LLC (the operator and joint owner of Quad Cities Station), insurance purchased directly by MidAmerican Energy, and the mandatory industry-wide loss funding mechanism afforded under the Price-Anderson Amendments Act of 1988. The general types of coverage are: nuclear liability, property coverage and nuclear worker liability.

NPPD and Exelon Generation each purchase nuclear liability insurance for Cooper and Quad Cities Station, respectively, in the maximum available amount of $200 million. In accordance with the Price-Anderson Amendments Act of 1988, excess liability protection above the amount is provided by a mandatory industry-wide program under which the licensees 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 Energy's aggregate maximum potential share of an assessment for Cooper and Quad Cities Station combined is $88.1 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 Station, Exelon Generation purchases primary and excess property insurance protection for the combined interests in Quad Cities Station, with coverage limits totaling $2.1 billion. For Cooper, MidAmerican Energy and NPPD separately purchase primary and excess property insurance protection for their respective obligations, with coverage limits of $1.375 billion each. This structure provides that both MidAmerican Energy and NPPD are covered for their respective 50% obligation in the event of a loss totaling up to $2.75 billion. MidAmerican Energy also directly purchases extra expense/business interruption coverage for its share of replacement power and/or other extra expenses in the event of a covered accidental outage at Cooper or Quad Cities Station. The coverages purchased directly by MidAmerican Energy, and the property coverages purchased by Exelon Generation, which includes the interests of MidAmerican Energy, are underwritten by an industry mutual insurance company and 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 Energy from industry mutual policies for its obligations associated with Cooper and Quad Cities Station combined, total $20.5 million.

The master nuclear worker liability coverage, which is purchased by NPPD and Exelon Generation for Cooper and Quad Cities Station, respectively, is an industry-wide guaranteed-cost policy with an aggregate limit of $200 million for the nuclear industry as a whole, which is in effect to cover tort claims in nuclear-related industries.

E. COOPER LITIGATION

On July 23, 1997, the Nebraska Public Power District ("NPPD") filed a complaint, in the United States District Court for the District of Nebraska, naming MidAmerican Energy as the defendant and seeking

F-60

declaratory judgment as to three issues under the parties' long-term power purchase agreement for Cooper capacity and energy. More specifically, the NPPD sought a declaratory judgment in the following respects:

(1) that MidAmerican Energy is obligated to pay 50% of all costs and expenses associated with decommissioning Cooper, and that in the event NPPD continues to operate Cooper after expiration of the power purchase agreement (September 2004), MidAmerican Energy is not entitled to reimbursement of any decommissioning funds it has paid to date or will pay in the future;

(2) that the current method of allocating transition costs as a part of the decommissioning cost is proper under the power purchase agreement; and

(3) that the current method of investing decommissioning funds is proper under the power purchase agreement.

MidAmerican Energy filed its answer and counterclaims. The counterclaims filed by MidAmerican Energy are generally as follows:

(1) that MidAmerican Energy has no duty under the power purchase agreement to reimburse or pay 50% of the decommissioning costs unless conditions to reimbursement occur;

(2) that the term "monthly power costs" as defined in the power purchase agreement does not include costs and expenses associated with decommissioning the plant;

(3) that NPPD violated MidAmerican Energy's directions for application of payments;

(4) that transition costs are not included in any decommissioning costs and are not any kind of costs that MidAmerican Energy is obligated to pay;

(5) that NPPD has the duty to repay all amounts that MidAmerican Energy has prefunded for decommissioning in the event the Nebraska Public Power District operates the plant after the term of the power purchase agreement;

(6) that NPPD is equitably estopped from continuing to operate the plant after the term of the power purchase agreement so long as NPPD does not repay all amounts MidAmerican Energy has prefunded for estimated decommissioning costs together with other amounts in certain funds and accounts and for so long as NPPD fails to provide MidAmerican Energy with certain requested accountings and information;

(7) that certain funds, accounts, and reserves are excessive and are required to be paid to MidAmerican Energy or credited to MidAmerican Energy's pre-2004 monthly power costs;

(8) that MidAmerican Energy has no duty to pay for nuclear fuel, operations and maintenance projects or capital improvements that have useful lives after the term of the power purchase agreement;

(9) that NPPD has mismanaged the plant in numerous described transactions resulting in damage to MidAmerican Energy;

(10) that NPPD has breached its contractual and other duties to MidAmerican Energy by not joining certain litigation and by failing to credit or agree to credit MidAmerican Energy with any recovery for low-level radioactive waste; and

(11) that NPPD has breached its duty to MidAmerican Energy in making investments of decommissioning funds;

On October 6, 1999, the court rendered summary judgment for NPPD on the above-mentioned issue concerning liability for decommissioning (issue one in the first paragraph above) and the related contingent counterclaims filed by MidAmerican Energy (issues one and two in the second paragraph above). The court referred all remaining issues in the case to mediation, and cancelled the November 1999 trial date.

F-61

MidAmerican Energy appealed the court's summary judgment ruling. On December 12, 2000, the United States Court of Appeals for the Eighth Circuit reversed the ruling of the district court and granted summary judgment in favor of MidAmerican Energy on issues one and five in the second paragraph above. Additionally, it remanded the case for trial on all other claims and counterclaims.

Since the remand to the District Court from the Eighth Circuit Court of Appeals, NPPD has been granted permission, over MidAmerican Energy's objections, to file a second amended complaint. The second amended complaint asserts that even though the Eighth Circuit Court of Appeals held that MidAmerican Energy has no liability under the power purchase agreement to reimburse or pay NPPD a 50% share of decommissioning costs unless certain conditions occur, MidAmerican Energy has unconditional liability for a 50% share based on agreements other than the power purchase agreement as originally written. NPPD's post-remand contentions - all strongly disputed by MEC - are that MidAmerican Energy has unconditional liability for a 50% share of decommissioning based on any of the following alternative theories: (i) the parties without written amendment either modified the power purchase agreement or made a separate agreement that imposes unconditional liability on MidAmerican Energy for decommissioning costs; (ii) absent unconditional liability for a 50% share of decommissioning costs, MidAmerican Energy would be unjustly enriched; (iii) MidAmerican Energy has unconditional liability for a 50% share of decommissioning costs based on promissory estoppel; or (iv) NPPD is entitled to have the power purchase agreement reformed to provide that MidAmerican Energy has unconditional liability for a 50% share of decommissioning costs. In response to NPPD's second amended complaint, MidAmerican Energy filed its first amended answer and third amended counterclaims containing denials, several affirmative defenses, and the counterclaims summarized above. In the course of discovery, NPPD has contended that MidAmerican Energy has some responsibility for some costs of storage of spent fuel resulting from the operation of the plant during the term of the power purchase agreement. MidAmerican Energy disputes this. MidAmerican Energy recently filed a mandamus petition with Eighth Circuit Court of Appeals seeking an order of that court directing the District Court not to permit NPPD to pursue the above alternative theories at trial, since the above alternative theories appear to be contrary to the December 12, 2000 Eighth Circuit Court of Appeals decision. If such relief is not granted, MidAmerican Energy will strongly dispute at trial these contentions and theories put forth by NPPD. Trial in these matters has been recently rescheduled to being on September 9, 2002.

F. COAL AND NATURAL GAS CONTRACT COMMITMENTS

MidAmerican Energy has supply and related transportation contracts for its fossil fueled generating stations. The contracts, with expiration dates ranging from 2002 to 2007, require minimum payments of $80.3 million, $70.6 million, $36.2 million, $34.0 million and $2.6 million for the years 2002 through 2006, respectively, and $2.6 million for the total of the years thereafter. MidAmerican Energy expects to supplement these coal contracts with additional contracts and spot market purchases to fulfill its future fossil fuel needs.

MidAmerican Energy has contracts with various companies to purchase electric capacity. The contracts, with expiration dates ranging from 2002 to 2011, require minimum payments of $27.0 million, $30.5 million, $15.3 million, $2.9 million and $2.2 million for the years 2002 through 2006, respectively, and $11.0 million for the total of the years thereafter.

MidAmerican Energy has various natural gas supply and transportation contracts for its gas operations. The minimum commitments under these contracts are $56.6 million, $41.3 million, $13.4 million, $13.2 million and $13.0 million for the years 2002 through 2006, respectively, and $26.7 million for the total of the years thereafter.

21. SUBSEQUENT EVENTS

Debt issuance

On February 8, 2002, MidAmerican Energy issued $400 million of 6.75% medium-term notes due in 2031. The proceeds will be used to refinance existing debt and preferred securities and for other corporate purposes. On March 11, 2002, MidAmerican Energy redeemed its MidAmerican-obligated mandatorily redeemable preferred securities of subsidiary trust at 100% of the principal amount plus accrued interest.

F-62

Prudential California Acquisition

In February 2002, HomeServices completed its purchase of a majority interest in Prudential California Realty. The cash purchase price of Prudential California Realty was approximately $74 million, with an option to purchase the remaining interests. Additionally, HomeServices is obligated to pay a maximum earnout of $18.5 million calculated based on certain 2002 financial performance measures. The purchase price was financed using the Company's corporate revolver for $40 million which was contributed to HomeServices as equity and the remaining funds were borrowed from available credit under the HomeServices's $65 million revolving credit facility. It is anticipated that the borrowings in connection with this acquisition will be repaid from HomeServices generated funds. The acquisition will be accounted for by the purchase method of accounting, and the Company is in the process of completing the allocation of the purchase price to the assets acquired and liabilities assumed.

Kern River Acquisition

On March 7, 2002, the Company reached a definitive agreement with The Williams Companies, Inc. ("Williams") to acquire Williams' Kern River Gas Transmission Company, a 926-mile interstate pipeline transporting Rocky Mountain and Canadian natural gas to markets in California, Nevada and Utah. The purchase price was $956 million, including $506 million of assumed debt. As part of the agreement, the Company will continue the planned expansion of the Kern River system, a project that will more than double the pipeline's capacity with expected capital expenditures of approximately $1.2 billion. The purchase was completed on March 27, 2002.

The Kern River pipeline is an important route for the transmission of natural gas from the vast reserves in the Rocky Mountain states to the rapidly growing markets in Utah, Nevada and California. Constructed in 1992, Kern River extends 926 miles from Opal, Wyoming, to the San Joaquin Valley near Bakersfield, California, and has a design capacity of 835 million cubic feet per day.

In August 2001, Williams filed with FERC to more than double the capacity on the Kern River system by adding approximately 900 million cubic feet per day of additional capacity from Wyoming to California and markets in between. Upon completion of the expansion project in May 2003, Kern River will be capable of transporting 1.7 billion cubic feet of natural gas per day. When converted to electricity, that is enough energy to power approximately 10 million homes.

In connection with the acquisition of Kern River, the Company issued $323 million of Trust Preferred Securities and $127 million of convertible preferred stock to Berkshire Hathaway.

In addition to the acquisition of Kern River, the Company also announced its investment of $275 million in Williams, in exchange for shares of 9 7/8 percent cumulative convertible preferred stock of Williams. In connection with this investment, the Company issued $275 million of convertible preferred stock to Berkshire Hathaway.

23. EXCESS OF COST OVER FAIR VALUE OF NET ASSETS ACQUIRED:

On January 1, 2002, the Company adopted Statement of Financial Accounting Standards ("SFAS ") No. 142, "Goodwill and Other Intangible Assets," which establishes the accounting for acquired goodwill and other intangible assets. SFAS No. 142 requires that amortization of goodwill and indefinite-lived intangible assets be discontinued and that entities disclose net income for prior periods adjusted to exclude such amortization and related income tax effects, as well as a reconciliation from the originally reported net income to the adjusted net income. The Company's related amortization consists of goodwill amortization and the related income tax effect. Following is a reconciliation of net income as originally reported for the year ended December 31, 2001, the period March 14, 2000 through December 31, 2000, the period January 1, 2000 through March 13, 2000, and the year ended December 31, 1999,to adjusted net income (in thousands):

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the Registrant's directors and officers pursuant to the following provisions or otherwise, the Registrant has been advised that, although the validity and scope of the governing statute have not been tested in court, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In addition, indemnification may be limited by state securities laws.

Sections 490.850 through 490.858 of the Iowa Business Corporation Act (the "IBCA") permit corporations organized thereunder to indemnify directors, officers, employees and agents against liability under certain circumstances.
Section 490.851 of the IBCA provides that a corporation may indemnify its officers and directors if (i) the person acted in good faith, and (ii) the person reasonably believed, in the case of conduct in the person's official capacity with the corporation, that the conduct was in the corporation's best interests, and in all other cases, that the person's conduct was at least not opposed to the corporation's best interests, and (iii) in the case of any criminal proceeding, the person had no reasonable cause to believe the person's conduct was unlawful.

The Registrant's Amended and Restated Articles of Incorporation and Bylaws provide that the Registrant shall indemnify, to the fullest extent permitted by the IBCA, its directors, officers, employees and agents, (2) any person serving as the legal representative of a director, officer, employee or agent, and (3) any person who is or was serving at the request of the Registrant as director, officer or employee of another corporation, joint venture, partnership, trust or other venture. Such indemnification is provided by the Registrant to such persons for all reasonable expenses, liability and loss incurred in connection with any civil, criminal, administrative or investigative proceeding, formal or informal, to which the person is, or is threatened to be made a party, whether the basis of such proceeding is alleged action in an official capacity or any other capacity while serving as director, officer, or employee.

The Registrant's Amended and Restated Articles of Incorporation and Bylaws provides that if the proceeding for which indemnification is sought is by or in the right of the Registrant, indemnification may be made only for reasonable expenses and may not be made in any proceeding in which the person is adjudged liable to the Registrant. Further, any such person may not be indemnified in any proceeding that charges improper personal benefit to the person in which the person is adjudged to be liable.

The Registrant's Amended and Restated Articles of Incorporation and Bylaws allow the Registrant to maintain liability insurance to protect itself and any director, officer, employee, or agent against any expense, liability or loss whether or not the Registrant would have the power to indemnify such person against such incurred expense, liability, or loss.

The Registrant has also entered into indemnification agreements with certain directors and officers, and expects to enter into similar agreements with future directors and officers, to further assure such persons' indemnification as permitted by Iowa law.

The rights to indemnification conferred on any person by the Registrant's Amended and Restated Articles of Incorporation and Bylaws are not exclusive of any right which any person may have or acquire under any statute, provision of the Registrant's Amended and Restated Articles of Incorporation, Bylaws, agreement, or vote of shareholders or disinterested directors.

ITEM 22. UNDERTAKINGS.

The undersigned registrant hereby undertakes that, for the purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant, pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by any such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether or not such indemnification is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For purposes of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 90th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

SECTION 1.05. Notices, Etc., to Trustee and Company

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if in writing and mailed, first-class, postage prepaid, to the Trustee at its Corporate Trust Office, or

(b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

If, by reason of the suspension of regular mail service or by reason of any other cause, it shall be impracticable to give such notice by mail, then such notification as shall be made at the direction of the Company in a manner reasonably calculated, to the extent practicable under the circumstances, to provide prompt notice shall constitute a sufficient notification for every purpose hereunder.

Any notice required or permitted hereunder may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Such Global Securities shall be duly executed by the Company and authenticated by the Trustee as hereinafter provided, and deposited with the Depositary, which will hold such Global Securities for the benefit of DTC.

(1) a written certificate from the Depositary, together with copies of certificates from Euroclear and Clearstream, certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Securities (except to the extent of any beneficial owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a 144A Global Security or a Restricted Definitive Security, all as contemplated by Section 3.07(d) hereof); and

(2) an Officers' Certificate from the Company,

Unless the Company determines otherwise in accordance with applicable law, the legend setting forth transfer restrictions shall be removed from a Restricted Definitive Security in accordance with the procedures set forth in Section 3.06(b) after such time as the applicable Holding Period shall have terminated, and each such Security shall thereafter be held as an "Unrestricted Security." As used herein, the term "Holding Period," with respect to Restricted Definitive Securities of any series, means the period referred to in Rule 144(k) or any successor provision thereto and as may be amended or revised from time to time, beginning from the later of (i) the original issue date of such Securities or (ii) the last date on which the Company or any affiliate of the Company was the beneficial owner of such Securities (or any predecessor thereof).

SUPPLEMENTAL THERETO PURSUANT TO WHICH THE SECURITIES OF THIS SERIES ARE BEING ISSUED] to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof.

[IF APPLICABLE, INSERT- This Security is not subject to redemption prior to maturity.]

[IF APPLICABLE, INSERT-The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of:

(1) 100% of the Principal Amount; or

(2) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus _____ basis points,

plus, for (1) or (2) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

32

"Comparable Treasury Price" means, with respect to any Redemption Date, (1) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (2) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

p.m. on the third Business Day in New York City preceding such Redemption Date).

Notice of redemption shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.]

[IF THE SECURITY IS A GLOBAL SECURITY- In the event of

redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.]

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

[IF THE SECURITY IS NOT AN ORIGINAL ISSUE DISCOUNT SECURITY,

INSERT- If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default

33

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and set forth in the Officers' Certificate referred to above or in any indenture supplemental hereto referred to above.

If any of the terms of the Securities of a series, including the form of Security of such series, are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by any authorized officer of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 3.03 for the authentication and delivery of such series of Securities.

SECTION 3.02. Denominations

The Securities of each series shall be issuable in bearer form or in registered form without coupons, except as otherwise expressly provided in a supplemental indenture hereto, in such denominations as shall be specified as contemplated by Section 3.01. In the absence of any such provisions with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple of $1,000.

SECTION 3.03. Execution, Authentication, Delivery and Dating

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Vice Presidents. The signature of any such Person on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signature of any Person who was at any time the proper officer of the Company shall bind the Company, notwithstanding that such Person has ceased to hold such office prior to the authentication and delivery of such Securities or did not hold such office at the date of authentication of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with an instrument or instruments establishing such series of Securities as contemplated in Section 3.01 hereof, and a Company Order for the authentication

53

and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01 and 6.03) shall be fully protected in relying upon, an Opinion of Counsel stating,

(a) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture;

(b) that the terms of such Securities have been established in conformity with the provisions of this Indenture; and

(c) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors' rights and to general principles of equity and such other matters as counsel may specify therein.

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the documents otherwise required pursuant to Sections 2.01 and 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the time of authentication upon original issuance of the first Security of such series to be issued and reasonably contemplate the issuance of each Security of such series.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.10 together with a written statement (which need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 3.04. Temporary Securities

Pending the preparation of definitive Securities of any series, the Company may execute, and upon compliance by the Company with Section 3.03, the Trustee or the Authenticating Agent shall authenticate and deliver, temporary Securities which are printed,

54

lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized, in bearer form, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder except as provided in Section 3.06 (if in connection with a transfer). Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee or the Authenticating Agent shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor.

Upon any exchange of a portion of a temporary Global Security for a definitive Global Security for the individual Securities represented thereby pursuant to this Section 3.04 or Section 3.05, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount of such temporary Global Security, and such principal amount shall be reduced for all purposes by the amount so exchanged and endorsed.

SECTION 3.05. Registrar and Paying Agent; Registration, Registration of Transfer and Exchange

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration, transfer and exchange of Securities. The Company shall maintain an office or agency of the Paying Agent in any Place of Payment where Securities of a series may be presented for payment. The Company may have one or more co-registrars and one or more additional paying agents, and the terms "Security Exchange Agent/Registrar" and "Paying Agent" shall include any additional co-registrars and paying agents, respectively.

The Company shall enter into an appropriate agency agreement with any Securities Exchange Agent/Registrar, Paying Agent or additional co-registrars or paying agents not a party to this Indenture, which shall incorporate the terms of the Trust Indenture Act and the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Security Exchange Agent/Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 6.07. The Company may act as Security Exchange Agent/Registrar or Paying Agent.

55

The Company hereby initially appoints the Trustee as "Security Exchange Agent/Registrar" for the purpose of registering Securities and transfers of Securities, and for the purpose of exchanging Securities, and as Paying Agent, all as herein provided.

Upon surrender for registration of transfer of any Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee or the Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

At the option of the Holder, any Security or Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and upon receipt of a Company Order the Trustee or the Authenticating Agent shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities as provided in this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Exchange Agent/Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made to the Holder for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption under Section 11.04 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, provided that such Security shall be immediately surrendered for redemption with written instructions for payment consistent with the provisions of this Indenture.

The provisions of this Section 3.05 are, with respect to any Global Security, subject to Section 3.07 hereof.

56

SECTION 3.06. Restricted Securities

(a) Transfer and Exchange.

(i) In General. Every Restricted Security shall be subject to the restrictions on transfer provided in the applicable legend(s) required to be set forth on the face of each Restricted Security pursuant to Section 2.01 or as provided pursuant to Section 3.01, unless such restrictions on transfer shall be waived or modified, in accordance with applicable laws, by the written consent of the Company. Each Holder of a Restricted Security, by its acceptance thereof, agrees to be bound by such restrictions on transfer.

(ii) Special Provisions Regarding Transfer of Restricted Securities. Unless expressly provided otherwise in the Indenture, whenever any Restricted Definitive Security is presented or surrendered for registration of transfer, such Restricted Definitive Security must be accompanied by a certificate in substantially the form set forth in or contemplated by Section 3.13(c) (which may be attached to or set forth in the Restricted Definitive Security), appropriately completed, dated the date of such surrender and signed by the Holder of such Restricted Definitive Security, as to compliance with such restrictions on transfer, unless the Company shall have notified the Trustee that there is an effective registration statement under the Securities Act with respect to such Restricted Definitive Security. Neither the Security Exchange Agent/Registrar nor any Transfer Agent shall be required to accept for such registration of transfer or exchange any Restricted Definitive Security not so accompanied by a properly completed certificate.

(b) Removal of Transfer Restrictions.

Unless with respect to the whole or any portion of any Restricted Security the Company determines otherwise in accordance with applicable law, transfer restrictions and any restrictive legend(s) with respect to Restricted Securities of any series shall be removed by the Company (i) in the case of Rule 144A Securities and Restricted Definitive Securities, upon presentation of such Security by the Holder at any time on or after the expiration of the Holding Period, or (ii) in the case of Regulation S Securities, upon presentation of such Security by the Holder at any time on or after the expiration of the Restricted Period. Thereafter, upon registration of transfer of or exchange of such Securities, the Company shall execute, and the Trustee shall authenticate and deliver, an Unrestricted Security.

Except as otherwise provided in the preceding paragraph, if Securities are issued upon the registration of transfer, exchange or replacement of Securities bearing a legend or legends setting forth restrictions on transfer, or if a request is made to remove such legend(s) from a Security, the Securities so issued shall bear such legend(s), or such legend(s) shall not be removed, as the case may be, unless there is delivered to the Company such satisfactory evidence (which may include an opinion, reasonably satisfactory to the Company, of independent counsel experienced in matters of United States securities law) as may be reasonably required by the Company that neither such legend(s) nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 or Regulation S under the Securities Act or that such Securities are not "restricted securities" within

57

the meaning of Rule 144 under the Securities Act. Upon provision of such satisfactory evidence to the Company, the Trustee, at the direction of the Company, shall authenticate and deliver a Security that does not bear such legend(s). In the absence of bad faith on its part, the Trustee may conclusively rely upon such direction of the Company in authenticating and delivering a Security that does not bear such legend(s).

As used in this Section 3.06, the term "transfer" encompasses any sale, pledge or other transfer of any Securities referred to herein.

Notwithstanding anything else in this Indenture to the contrary, after a transfer of any Initial Securities or Private Exchange Securities during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring that any such Initial Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security without legends will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities or upon receipt of directions to transfer such Holder's interest in the Global Security, as applicable.

Notwithstanding anything else in this Indenture to the contrary, upon the consummation of a Registered Exchange Offer with respect to the Initial Securities pursuant to which Holders of such Initial Securities are offered Exchange Securities in exchange for their Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will cease to apply and certificated Initial Securities with the restricted securities legend set forth in Section 2.02 hereto will be available to Holders of such Initial Securities that do not exchange their Initial Securities and Exchange Securities in certificated form will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

Notwithstanding anything else in this Indenture to the contrary, upon the consummation of a Private Exchange with respect to the Initial Securities pursuant to which Holders of such Initial Securities are offered Private Exchange Securities in exchange for their Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain holders be issued in global form will still apply, and Private Exchange Securities in global form with the Restricted Securities legend set forth in Section 2.02 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange.

SECTION 3.07. Global Securities

(a) Form and Legend.

If the Company shall establish pursuant to Section 3.01 that certain of the Securities of a particular series are to be issued in the form of a Global Security, then the Company shall execute and the Trustee shall, in accordance with Section 3.03, authenticate and deliver, a Global Security or Securities which (i) shall represent, and shall be denominated in an aggregate amount equal to the aggregate principal amount of, all of the Securities of such series

58

to be so represented, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary for such series or pursuant to the Depositary's instruction and (iv) shall bear a legend substantially to the effect of the first two paragraphs of the form of face of Security set forth in Section 2.02.

(b) Transfer and Exchange.

(i) Transfers of Global Securities as such. Except as otherwise expressly provided in this Indenture or any supplement hereto, a Global Security representing all or a portion of the Securities of a series may not be transferred in global form, except as a whole (i) by the Depositary for such series to a nominee of such Depositary, (ii) by a nominee of such Depositary to such Depositary or another nominee of such Depositary or (iii) by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary.

(ii) Exchanges of Global Securities for Definitive Securities. A Global Security of a series shall be exchangeable, in whole but not in part, for definitive Securities of such series if (a) DTC notifies the Company and the Depositary that it is unwilling or unable to continue to hold book-entry interests in such Global Security or DTC at any time ceases to be a "clearing agency" registered as such under the Exchange Act, and, in either case, a successor is not appointed by the Company within 120 days, (b) while a Global Security is a Restricted Security the book-entry interests in such Global Security cease to be eligible for DTC services because the Securities of such series are neither (i) rated in one of the top four categories by a nationally recognized statistical rating organization nor (ii) included within a Self-Regulatory Organization system approved by the Commission for the reporting of quotation and trade information of securities eligible for transfer pursuant to Rule 144A, such as the PORTAL system, (c) the Depositary for Securities of such series notifies the Company that it is unwilling or unable to continue as Depositary with respect to such Global Security and no successor is appointed within 120 days or (d) the Company in its sole discretion executes and delivers to the Trustee an Officers' Certificate providing that such Global Security shall be so exchangeable; provided that in no event shall the Regulation S Temporary Global Securities be exchanged by the Company for Definitive Securities prior to (x) the expiration of the Restricted Period and (y) the receipt by the Security Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. Securities so issued in exchange for any such Global Security shall be of the same series, having the same interest rate, if any, and maturity and having the same terms as such Global Security, in authorized denominations and in the aggregate having the same principal amount as such Global Security and registered in such names as the Depositary for such Global Security shall direct based on the instructions of DTC. Upon such exchange, the surrendered Global Security shall be cancelled by the Trustee.

A Global Security of a series shall be exchangeable, in whole or in part, for definitive Registered Securities of such series if there shall have occurred and be continuing an Event of Default with respect to the Securities of such series and the Holder, in such circumstances, shall have requested in writing that all or a part of the Global Security of such series be exchanged for one or more Definitive Securities (an

59

"Optional Definitive Security Request"), provided that in no event shall the Regulation S Temporary Global Securities be exchanged by the Company for definitive Registered Securities prior to (x) the expiration of the Restricted Period and (y) the receipt by the Security Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. Upon any such surrender, (i) the Company shall execute and the Trustee shall authenticate and deliver without charge to each Person specified by DTC, in exchange for such Person's beneficial interest in the Global Security, a new Security or Securities of the same series in definitive registered form having the same interest rate, if any, and maturity and having the same terms as such Global Security, in any authorized denomination requested by such Person and in an aggregate principal amount equal to such Person's beneficial interest in the Global Security, and (ii) if the Global Security is being exchanged (x) as a whole, then the surrendered Global Security shall be cancelled by the Trustee, or (y) in part, then the principal amount of the surrendered Global Security shall be reduced by an endorsement on Schedule A thereto in the appropriate amount.

Unless otherwise provided pursuant to a Board Resolution, Officers' Certificate or supplemental indenture in accordance with
Section 3.01, Definitive Securities issued in exchange for a Global Security pursuant to this Section 3.07(b)(ii) shall be issued only in registered form and shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from DTC and its Participants or Indirect Participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

(c) Beneficial Interests.

Subject to Section 3.06 and Section 3.07, beneficial interests in a Global Security may be transferred in any manner consistent with the Applicable Procedures.

(d) Special Provisions Regarding Transfer of Beneficial Interests in a Regulation S Global Security.

The transfer of beneficial interests in a Regulation S Global Security shall be effected in a manner not inconsistent with the following provisions:

(i) Transfer Through a Rule 144A Global Security. If the holder of a beneficial interest in a Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in a Rule 144A Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section 3.07(d)(i) provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Temporary Global Securities may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an initial purchaser). Upon receipt by the Depositary of the instructions, order and certificate set forth below, the Depositary shall promptly forward the same to the Security Exchange Agent/Registrar at the Corporate Trust Office. Upon receipt by the Security Exchange Agent/Registrar from the

60

Depositary at the Corporate Trust Office of (1) written instructions given in accordance with the Applicable Procedures from a Participant directing the Depositary to cause to be credited to a specified Participant's account a beneficial interest in the Rule 144A Global Security equal to that of the beneficial interest in the Regulation S Global Security to be so transferred, (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Participant to be credited with, and the account of the Participant held for Euroclear or Clearstream to be debited for, such beneficial interest, and (3) a certificate substantially in the form set forth in or contemplated by Section 3.13(a) given by the transferor of such beneficial interest, the Security Exchange Agent/Registrar, shall (A) reduce the principal amount of the Regulation S Global Security, and increase the principal amount of the Rule 144A Global Security, in each case by an amount equal to the principal amount of the beneficial interest in the Regulation S Global Security to be so transferred, as evidenced by appropriate endorsements on Schedule A of the respective Global Securities, and (B) instruct the Depositary, which shall instruct DTC,
(x) to make corresponding reductions and increases in the amounts represented by the respective Global Securities and (y) to cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security having a principal amount equal to the amount by which the principal amount of the Regulation S Global Security was reduced upon such transfer.

Delivery of a beneficial interest in the Regulation S Global Security of any series may not be taken in the form of a beneficial interest in the Rule 144A Global Security if immediately prior to the contemplated transfer no Rule 144A Global Security of the same series is then Outstanding.

(ii) Interests in Regulation S Global Security Initially to be Held Through Euroclear or Clearstream. Beneficial interests in a Regulation S Temporary Global Security may be held only through Participants acting for and on behalf of Euroclear or Clearstream.

(iii) Transfer Through Restricted Definitive Security. If the holder of a beneficial interest in a Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a Restricted Definitive Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section 3.07(d)(iii), provided that in no event shall the Regulation S Temporary Global Securities be exchanged by the Company for Restricted Definitive Securities prior to (x) the expiration of the Restricted Period and (y) the receipt by the Security Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. Upon receipt by the Depositary of the instructions and certificate set forth below, the Depositary shall promptly forward the same to the Security Exchange Agent/Registrar at the Corporate Trust Office. Upon receipt by the Security Exchange Agent/Registrar from the Depositary at the Corporate Trust Office of (1) written instructions given in accordance with the Applicable Procedures from a Participant directing the Depositary to cause to be issued a Restricted Definitive Security to such Person in a principal amount equal to that of the beneficial interest in the Global Security to be so transferred and (2) a certificate substantially in the form set forth in or

61

contemplated by Section 3.13(f) given by the transferor of such beneficial interest, the Security Exchange Agent/Registrar shall (A) reduce the principal amount of the Regulation S Global Security by an amount equal to the principal amount of the beneficial interest in the Regulation S Global Security to be so transferred, as evidenced by appropriate endorsement on Schedule A of the Regulation S Global Security and (B) cause to be issued a Restricted Definitive Security to such Person in a principal amount equal to the amount by which the principal amount of the Regulation S Global Security was reduced upon such transfer.

(iv) Transfer Through an Unrestricted Global Security. If the holder of a beneficial interest in a Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section
3.07(d)(iv). Upon receipt by the Depositary of the instructions, order and certificate set forth below, the Depositary shall promptly forward the same to the Security Exchange Agent/Registrar at the Corporate Trust Office.

SECTION 3.08. Mutilated, Destroyed, Lost and Stolen Securities

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such Security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

66

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security, in each such case without premium or penalty.

Upon the issuance of any new Security under this Section 3.08, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this
Section 3.08 in exchange for any mutilated Security or in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section 3.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.09. Payment of Interest; Interest Rights Reserved

Except as may otherwise be established as contemplated by
Section 3.01 with respect to any series of Securities, interest on any Security which is payable and is punctually paid or duly provided for on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Payment of interest, if any, in respect of any Security will be made by check mailed to the address of the Person entitled thereto at such Person's address appearing in the Security Register. Payment of interest, if any, in respect of any Security may also be made, in the case of a Holder of at least U.S. $1,000,000 aggregate principal amount of Securities, and payment of interest, if any, in respect of a Permanent Global Security shall be made, by wire transfer to a U.S. Dollar account maintained by the Holder with a bank in the United States; provided that such Holder elects payment by wire transfer by giving written notice to the Trustee or a Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Any interest on any Security of any series which is payable but is not punctually paid or duly provided for on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such

67

Defaulted Interest, which shall be fixed in the following manner: The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. Unless the Trustee is acting as the Security Exchange Agent/Registrar, promptly after such Special Record Date, the Company shall furnish the Trustee with a list, or shall make arrangements satisfactory to the Trustee with respect thereto, of the names and addresses of, and respective principal amounts of such Securities held by, the Holders appearing on the Security Register at the close of business on such Special Record Date. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any Securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange.

Subject to the foregoing provisions of this Section 3.09, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security, shall carry the Rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.10. Persons Deemed Owners

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 3.09) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. All such payments so made to any such Person, or upon such Person's order, shall be valid, and, to the extent of the sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Security.

68

Holders of beneficial interests in a Global Security of any series will not be entitled to receive certificates therefor, except in the limited circumstances set forth in Section 3.07(b)(ii). No holder of any beneficial interest in a Global Security shall have any rights under this Indenture with respect to such Global Security.

The Trustee shall not deem requests or directions from, or votes by, the Depositary for a Global Security of any series to be inconsistent if made on behalf of different holders of beneficial interests.

SECTION 3.11. Cancellation

All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee and disposed of in its customary manner. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 3.11 except as expressly permitted by this Indenture.

SECTION 3.12. Computation of Interest

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest, if any, on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.13. Certification Form

(2) an Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940; and

Section 15 of the New York Debtor and Creditor Law or (B) 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 subsection (c)(ii) of this Section 4.02 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;

87

(iv) if at such time the Securities are listed on a national securities exchange, the Company has delivered to the Trustee an Opinion of Counsel to the effect that the Securities will not be delisted as a result of such deposit, defeasance and discharge;

(vi) if the Trust Indenture Act shall be applicable to the Securities of such series, such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

88

SECTION 4.04. Reinstatement

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 4.01 or 4.02 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 4.03 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in Trust.

SECTION 5.02. Acceleration of Maturity; Rescission and Annulment

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then either the Trustee or (i) in the case of an Event of Default described under subsection (a) or (b) of Section 5.01 above, the Holders of at least 33% in aggregate principal amount of the Outstanding Securities, or (ii) in the case of any other Event of Default, the Holders of a majority in aggregate principal amount of the Outstanding Securities, may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof), and any interest accrued thereon, of all of the Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default described under subsection (g) or (h) of Section 5.01 occurs, the entire principal amount of the Outstanding Securities, plus any accrued interest thereon, shall become immediately due and payable without any action by the Trustee, the Holders or any other Person.

At any time after such declaration of acceleration with respect to Securities of any series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as hereinafter in this Article provided, if all Events of Default with respect to Securities have been cured or waived (other than the non-payment of principal of the Securities which has become due solely by reason of such declaration of acceleration), then, and in every such case, the Holders of a majority in aggregate principal amount of the Outstanding Securities may, by written notice to the Company and the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall affect any subsequent default or impair any right consequent thereon.

For all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities.

SECTION 5.03. Collection of Debt and Suits for Enforcement by Trustee

The Company covenants that if

(a) default is made in the payment of any interest on any Security of a series when such interest becomes due and payable and such default continues for a period of 30 days, or

91

(b) default is made in the payment of the principal of (or premium, if any, on) any Security of a series at the Stated Maturity thereof or in any payment on such Security required in connection with a Change of Control, the Company will, upon written demand of the Trustee, pay to it, for the benefit of the Holders of such Securities of such series, the whole amount then due and payable on such Securities of such series for principal (and premium, if any) and interest, if any, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and any overdue interest, at the rate or rates prescribed therefor in such Securities of such series, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If any Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights.

SECTION 5.04. Trustee May File Proofs of Claim

In case of the pendency of any receivership, insolvency, liquidation (other than a solvent liquidation), bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(a) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the

92

Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.05. Trustee May Enforce Claims Without Possession of Securities

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 5.06. Application of Money Collected

Any money collected by the Trustee pursuant to this Article shall be applied in the following order with respect to the Securities of any series, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under
Section 6.07;

SECOND: In case the principal and premium, if any, of the Securities of such series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest, if any, on the Securities of such a series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee and to the extent permitted by law) upon the overdue installments of interest at the rate prescribed therefor in such Securities, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference;

THIRD: In case the principal or premium, if any, of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and premium, if any, and interest, if any, with interest upon the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee and to the extent permitted by law) upon overdue installments of interest at the rate prescribed therefor in the Securities of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and any premium and interest, without preference or priority of principal over interest, or of interest over principal or premium, or of any installment of interest

93

over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal and any premium and accrued and unpaid interest; and

FOURTH: To the payment of the remainder, if any, to the Company.

SECTION 5.07. Limitation on Suits

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities;

(b) (i) in the case of an Event of Default described under subsection (a) or (b) of Section 5.01 above, the Holders of at least 33% in aggregate principal amount of the Outstanding Securities, or (ii) in the case of any other Event of Default, the Holders of a majority in aggregate principal amount of the Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(c) such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustee for 90 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e) no direction inconsistent with such written request has been given to the Trustee during such 90-day period by the Holders of a majority in principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

SECTION 5.08. Unconditional Right of Holders to Receive Principal, Premium and Interest

Subject to Section 5.07, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 3.11) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

94

SECTION 5.09. Restoration of Rights and Remedies

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Company, the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 5.10. Rights and Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 5.11. Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient by the Trustee or by the Holders, as the case may be.

SECTION 5.12. Control by Holders

The Holders of a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities, provided that

(a) such direction shall not be in conflict with any rule of law or with this Indenture,

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(c) the action so directed would not be prejudicial to Holders of any other series of Outstanding Securities not taking part in such action; provided, further, that the Trustee shall be under no obligation to determine whether any such direction shall be so prejudicial.

95

SECTION 5.13. Waiver of Past Defaults

The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default

(a) in the payment of the principal of (or premium, if any) or interest, if any, on any Security, or in any payment on such Security required in connection with a Change of Control, or

(b) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 5.14. Undertaking for Costs

All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant in such suit, but the provisions of this Section 5.14 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest, if any, on any Security on or after the Stated Maturity or Maturities expressed in such Security.

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (1) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (2) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

101

of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

SECTION 6.11. Acceptance of Appointment by Successor

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to

102

the Securities of that or those series to which the appointment of such successor Trustee relates; but on request of the Company or any successor trustee, such retiring Trustee shall upon payment of its charges hereunder duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section 6.11, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.13. Preferential Collecting of Claims Against Company

(a) Subject to subsection (b) of this Section 6.13, if the Trustee shall be or shall become a creditor, directly or indirectly, secured or unsecured, of the Company within three months prior to a default, as defined in subsection (c) of this Section 6.13, or subsequent to such a default, then, unless and until such default shall be cured, the Trustee shall set apart and hold in a special account for the benefit of the Trustee individually, the Holders of the Securities and the holders of other indenture securities, as defined in subsection (c) of this Section 6.13:

(i) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of principal or interest effected after the beginning of such three-month period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in paragraph (ii) of this subsection (a), or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been applied by or against the Company upon the date of such default; and

(ii) all property received by the Trustee in respect of any claims as such creditor, either as security therefor, or in satisfaction or composition thereof, or otherwise, after the beginning of such three-month period, or an amount equal to the

103

proceeds of any such property, if disposed of, subject, however, to the rights, if any, of the Company and its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

(1) to retain for its own account (A) payments made on account of any such claim by any Person (other than the Company) who is liable thereon, and (B) the proceeds of the bona fide sale of any such claim by the Trustee to a third Person, and (C) distributions made in cash, securities or other property in respect of claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law;

(2) to realize, for its own account, upon any property held by it as security for any such claim, if such property was so held prior to the beginning of such three-month period;

(3) to realize, for its own account, but only to extent of the claim hereinafter mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such three-month period and such property was received as security therefor simultaneously with the creation thereof, and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default, as defined in subsection (c) of this Section 6.13, would occur within three months; or

(4) to receive payment on any claim referred to in paragraph (2) or (3) of this subsection, against the release of any property held as security for such claim as provided in paragraph (2) or (3), as the case may be, to the extent of the fair value of such property.

For the purposes of paragraphs (2), (3) and (4) of this
Section 6.13, property substituted after the beginning of such three-month period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of or in substitution for or for the purpose of repaying or refunding any preexisting claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim.

If the Trustee shall be required to account for the funds and property held in such special account, the proceeds thereof shall be apportioned among the Trustee, the Holders and the holders of other indenture securities in such manner that the Trustee, the Holders and the holders of other indenture securities realize, as a result of payments from such special account and payments of dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, as applicable, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such special account and before crediting to the respective claims of the Trustee and the Holders and the holders of other indenture securities dividends on claims filed against the

104

Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, as applicable, but after crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special account. As used in this paragraph, with respect to any claim, the term "dividends" shall include any distribution with respect to such claim, in bankruptcy or receivership or proceedings for reorganization pursuant to the Federal Bankruptcy Act or applicable State law, as applicable, whether such distribution is made in cash, securities or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim.

Any Trustee which has resigned or been removed after the beginning of such three-month period shall be subject to the provisions of this
Section 6.13 as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such three-month period, it shall be subject to the provisions of this subsection if and only if the following conditions exist:

(i) the receipt of property or reduction of claim, which would have given rise to the obligation to account, if such Trustee had continued as Trustee, occurred after the beginning of such three-month period; and

(ii) such receipt of property or reduction of claim occurred within three months after such resignation or removal.

(b) There shall be excluded from the operation of subsection
(a) of this Section 6.13 a creditor relationship arising from:

(i) the ownership or acquisition of securities issued under any indenture, or any security or securities having a maturity of one year or more at the time of acquisition by the Trustee;

(ii) advances authorized by a receivership or bankruptcy court of competent jurisdiction or by this Indenture, for the purpose of preserving any property which shall at any time be subject to the lien of this Indenture or of discharging tax liens or other prior liens or encumbrances thereon, if notice of such advances and of the circumstances surrounding the making thereof is given to the Holders at the time and in the manner provided in this Indenture;

(iii) disbursements made in the ordinary course of business in the capacity of trustee under an indenture, transfer agent, registrar, custodian, paying agent, fiscal agent or depository, or other similar capacity;

(iv) an indebtedness created as a result of services rendered or premises rented; or an indebtedness created as a result of goods or securities sold in a cash transaction, as defined in subsection (c) of this Section 6.13;

(v) the ownership of stock or of other securities of a corporation organized under the provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or indirectly a creditor of the Company; and

105

(vi) the acquisition, ownership, acceptance or negotiation of any drafts, bills of exchange, acceptances or obligations which fall within the classification of self-liquidating paper, as defined in subsection (c) of this Section 6.13.

(c) For the purposes of this Section 6.13 only:

(i) the term "default" means any failure to make payment in full of the principal of or interest on any of the Securities or upon the other indenture securities when and as such principal or interest becomes due and payable;

(ii) the term "other indenture securities" means securities upon which the Company is an obligor (as defined in the Trust Indenture Act) outstanding under any other indenture (1) under which the Trustee is also trustee, (2) which contains provisions substantially similar to the provisions of this Section 6.13, and (3) under which a default exists at the time of the apportionment of the funds and property held in such special account;

(iii) the term "cash transaction" means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand;

(iv) the term "self-liquidating paper" means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation;

(v) the term "Company" means any obligor upon the Securities; and

(vi) the term "Federal Bankruptcy Act" means the Bankruptcy Code or Title 11 of the United States Code.

SECTION 6.14. Authenticating Agents

From time to time the Trustee, with the prior written approval of the Company, may appoint one or more Authenticating Agents with respect to one or more series of Securities with power to act on the Trustee's behalf and subject to its direction in the authentication and delivery of Securities of such series issued upon original issuance and upon exchange, registration of transfer or partial redemption thereof or in connection with transfers and exchanges under Sections 3.04, 3.05, 3.06, 3.07, 3.08 and 11.07 as fully to all intents and purposes as though the Authenticating Agent had been expressly authorized by those Sections of this Indenture to authenticate and deliver Securities of such series. For all purposes of this Indenture, the authentication and delivery of Securities by an Authenticating Agent pursuant to

106

this Section 6.14 shall be deemed to be authentication and delivery of such Securities "by the Trustee". Each such Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any State thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by Federal, State or District of Columbia authority. If such corporation publishes reports of condition at least annually pursuant to law or the requirements of such authority, then for the purposes of this Section 6.14 the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.14, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 6.14.

Any corporation into which any Authenticating Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation or to which any Authenticating Agent shall be a party, or any corporation succeeding to the corporate trust business of any Authenticating Agent, shall be the successor of the Authenticating Agent hereunder, if such successor corporation is otherwise eligible under this
Section 6.14, without the execution or filing of any paper or any further act on the part of the parties hereto or the Authenticating Agent or such successor corporation.

An Authenticating Agent may resign at any time by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible under this Section 6.14, the Trustee may appoint a successor Authenticating Agent with the prior written approval of the Company and shall mail notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as the names and addresses of such Holders appear on the Security Register. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.14.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.14 as may be agreed in a separate writing among the Company, the Trustee and such Authenticating Agent, and the Trustee shall be entitled to be reimbursed for such payments pursuant to Section 6.07.

If an appointment with respect to one or more series of Securities is made pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Securities of the series designated herein referred to in the within mentioned Indenture.

The Company will give prompt written notice to the Trustee of the location, and any change in the location, of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, all such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee and the Company hereby appoints the Paying Agent as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies (in or outside of such Place of Payment) where the Securities of one or more series and any appurtenant coupons may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for any series of Securities for such purposes. The Company will give prompt written notice to the Trustee of any such designation and any change in the location of any such other office or agency.

SECTION 10.03. Money for Securities Payments to Be Held in Trust

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest, if any, so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, no later than 10:00 a.m. New York City Time, on each due date of the principal of (and premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum in immediately available funds sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto.

The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 10.03, that such Paying Agent will:

(a) hold all sums held by it for the payment of the principal of (and premium, if any) or interest, if any, on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(c) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by the Company or by any Paying Agent to the Trustee, the Company or such Paying Agent, as the case may be, shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest, if any, on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

SECTION 10.04. Limitation on Liens

The Company 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 the Company to secure any Indebtedness for Borrowed Money, without making effective provisions whereby the Outstanding Securities shall be equally and ratably secured with any and all such Indebtedness for Borrowed Money and with any other Indebtedness for Borrowed Money similarly entitled to be equally and ratably secured; provided, however, that this Section 10.04 shall not apply to or prevent the creation or existence of:

(b) purchase money Liens which do not exceed the cost or value of the purchased property or assets;

(c) any Liens not to exceed 10% of Consolidated Net Tangible Assets; and

(d) any Liens on property or assets granted in connection with extending, renewing, replacing or refinancing in whole or in part the Indebtedness for Borrowed Money (including, without limitation, increasing the principal amount of such Indebtedness for Borrowed Money) secured by Liens described in the foregoing clauses (a) through (c), 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.

116

In the event that the Company proposes to pledge, mortgage, hypothecate or permit to exist any mortgage, pledge or other Lien upon any property or assets at any time directly owned by the Company to secure any Indebtedness for Borrowed Money, other than as permitted by clauses (a) through
(d) of the previous paragraph, the Company will give prior written notice thereof to the Trustee in accordance with Section 1.05 and the Company will, prior to or simultaneously with such pledge, mortgage or hypothecation, effectively secure all the Securities equally and ratably with such Indebtedness for Borrowed Money.

The Company and the Trustee shall execute and deliver all such other documents, instruments and agreements and do all such other acts and things as may be reasonably required to enable the Trustee to exercise and enforce its rights under this Indenture and under the documents, instruments and agreements required under this Indenture and to carry out the intent of this Indenture.

In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or pursuant to an election by the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction or condition.

If less than all the Securities of any series are to be redeemed, the particular securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions equal to the minimum authorized denomination for Securities of that series (or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series.

Any Security (including any Global Security) which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the

122

Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee upon written direction shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the security so surrendered; provided, that if a Global Security is surrendered for partial redemption, no new Global Security shall be issued but instead the principal amount of the surrendered Global Security shall be reduced by an endorsement to Schedule A to such Global Security by the Security Exchange Agent/Registrar equal to the redeemed portion of the principal of the Global Security so surrendered, whereupon such Global Security shall be delivered to the Depositary; and provided, further that following any such partial redemption the Securities selected for redemption and any beneficial interests therein shall not have had their principal amount reduced below the minimum authorized denomination for Securities of such series and for any beneficial interests therein.

ARTICLE XIII.

MISCELLANEOUS

SECTION 13.01. Consent to Jurisdiction; Appointment of Agent to Accept Service of Process

(a) The Company irrevocably consents and agrees, for the benefit of the Holders from time to time of the Securities and the Trustee, that any legal action, suit or proceeding against it with respect to its obligations, liabilities or any other matter arising out of or in connection with this Indenture or the Securities may be brought in the United States District Court for the Southern District of New York or in the Supreme Court of New York in New York County, and, until amounts due and to become due in respect of the Securities have been paid, hereby irrevocably consents and submits to the nonexclusive jurisdiction of each such court and any appellate court of either of them in personam, generally and unconditionally with respect to any action, suit or proceeding for itself and in respect of its properties, assets and revenues.

(b) The Company hereby designates, appoints and empowers CT Corporation System, acting through its office at 111 Eighth Avenue, New York, New York 10011, as the Company's designee, appointee and agent (the "Authorized Agent") to receive, accept and acknowledge for and on its behalf, and its properties, assets and revenues, service of any and all legal process, summons, notices and documents which may be served in any action, suit or proceeding brought against the Company pursuant to paragraph (a) of this Section. Such appointment shall be irrevocable until all amounts in respect of the principal of and any premium and interest due and to become due on or in respect of all the Securities issued under this Indenture have been paid by the Company to the Trustee pursuant to the terms hereof and of the Securities. Notwithstanding the foregoing, the Company reserves the right to appoint another Person satisfactory to the Trustee and located or with an office in the Borough of Manhattan, The City of New York, as a successor Authorized Agent, and upon acceptance of such appointment by such a successor, the appointment of the prior Authorized Agent shall terminate. The Company shall give notice to the Trustee and all Holders of the appointment by it of a successor Authorized Agent. If for any reason CT Corporation System ceases to be able to act as the Authorized Agent or to have an address in the Borough of Manhattan, The City of New York, the Company will appoint a successor Authorized Agent in accordance with the two preceding

125

sentences. The Company further agrees to take any and all action, including the filing of any and all documents and instruments as may be necessary to continue such designation and appointment of such agent in full force and effect until this Indenture has been satisfied and discharged in accordance with Article IV hereof. The Company further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents in any action, suit or proceeding against the Company by serving a copy thereof upon the relevant agent for service of process referred to in this Section 14.01 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or acknowledge such service) or by mailing copies thereof by registered or certified air mail, postage prepaid, to the Company at its address specified in or designated pursuant to this Indenture. The Company agrees that the failure of any such designee, appointee and agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. Nothing herein shall in any way be deemed to limit the ability of the Holders of the Securities and the Trustee to serve any such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Company or bring actions, suits or proceedings against the Company in such other jurisdictions, and in such manner, as may be permitted by applicable law. The Company irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this Indenture brought in the United States District Court for the Southern District of New York or in the Supreme Court of New York in New York County, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

If for the purpose of obtaining judgment in any Court it is necessary to convert a sum due hereunder to the Holder of any Security from U.S. dollars into another currency, the Company has agreed, and each Holder by holding such Security will be deemed to have agreed, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in The City of New York on the Business Day preceding the day on which final judgment is given.

The obligation of the Company in respect of any sum payable by it to the Holder of a Security shall, notwithstanding any judgment in a currency (the "judgment currency") other than Dollars, be discharged only to the extent that on the Business Day following receipt by the Holder of such security of any sum, adjudged to be so due in the judgment currency, the Holder of such Security may in accordance with normal banking procedures purchase Dollars with the judgment currency; if the amount of Dollars so purchased is less than the sum originally due to the Holder of such Security in the judgment currency (determined in the manner set forth in the preceding paragraph), the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder of such Security against such loss, and if the amount of the Dollars so purchased exceeds the sum originally due to the Holder of such Security, such Holder agrees to remit to the Company such excess, provided that such Holder shall have no obligation to remit any such excess as long as the Company shall have failed to pay such Holder any obligations due and payable under such Security, in which case such excess may be applied to such obligations of the Company under such Security in accordance with the terms thereof.

126

SECTION 13.02. Counterparts

This Indenture may be executed in any number of Counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $200,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

In the event of redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

3. DEFEASANCE

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

4. DEFAULTS AND REMEDIES

At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to Securities of this series have been cured or waived (other than the non-payment of principal of the Securities of this series which has become due solely by reason of such declaration of acceleration) then and in every such case, the Holders of a majority

R-2

in aggregate principal amount of the Outstanding securities of such series may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee, (c) such Holder shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding under the Indenture a direction inconsistent with such request and (e) the Trustee for 90 days after its receipt of such notice and offer of indemnity from the Holder, and request from the Holders, shall have failed to institute any such proceeding.

         MIDAMERICAN ENERGY HOLDINGS COMPANY, a corporation organized under the

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $200,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published

R-1

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

"Independent Investment Banker" means an investment banking institution of international standing appointed by the Company.

"Reference Treasury Dealer" means a primary U.S. government securities dealer in New York City appointed by the Company.

"Reference Treasury Dealer Quotation" means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day in New York City preceding such Redemption Date).

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

In the event of redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

3. DEFEASANCE

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

4. DEFAULTS AND REMEDIES

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to Securities of this series have been cured or waived (other than the non-payment of principal of the Securities of this series which has become due solely by

R-2

reason of such declaration of acceleration) then, and in every such case, the Holders of a majority in aggregate principal amount of the Outstanding securities under the Indenture may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding under the Indenture a direction inconsistent with such request and (e) the Trustee for 90 days after its receipt of such notice and offer of indemnity from the Holder, and request from the Holders, shall have failed to institute any such proceeding. The foregoing shall not apply to certain suits described in the Indenture, including any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

5. AMENDMENT AND WAIVER

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the Indenture or any supplemental indenture or the rights and obligations of the Company and rights of the Holders of the Securities of any series at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

R-3

6. TRANSFER AND EXCHANGE; DENOMINATIONS

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of a Security of the series of which this Security is a part is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest, if any, on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of the series of which this Security is a part are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Regulation S Temporary Global Security is exchangeable in whole or in part for one or more Global Securities only (i) on or after the termination of the 40-day distribution compliance period (as defined in Regulation S) and
(ii) upon presentation of certificates (accompanied by an Opinion of Counsel, if applicable) required by Article 2 of the Indenture. Upon exchange of this Regulation S Temporary Global Security for one or more Global Securities, the Trustee shall cancel this Regulation S Temporary Global Security.

7. SUCCESSOR OBLIGORS

When a successor assumes all the obligations of its predecessor under the Securities of this series and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

8. TRUSTEE DEALINGS WITH THE COMPANY

No stockholder, director, officer, employee, incorporator or Affiliate of the Company shall have any liability for any obligation of the Company under the Securities of this series or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of the Securities of this series by accepting a Security of this series waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities of this series.

10. AUTHENTICATION

This Security shall not be valid until the Trustee or authenticating agent signs the certificate of authentication on this Security.

11. ISIN NUMBER

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $200,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company at any time, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or
(ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published

R-1

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

"Independent Investment Banker" means an investment banking institution of international standing appointed by the Company.

"Reference Treasury Dealer" means a primary U.S. government securities dealer in New York City appointed by the Company.

"Reference Treasury Dealer Quotation" means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day in New York City preceding such Redemption Date).

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

In the event of redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

3. DEFEASANCE

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

4. DEFAULTS AND REMEDIES

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to Securities of this series have been cured or waived (other than the non-payment of principal of the Securities of this series which has become due solely by

R-2

reason of such declaration of acceleration) then, and in every such case, the Holders of a majority in aggregate principal amount of the Outstanding securities of such series may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding under the Indenture a direction inconsistent with such request and (e) the Trustee for 90 days after its receipt of such notice and offer of indemnity from the Holder, and request from the Holders shall have failed to institute any such proceeding. The foregoing shall not apply to certain suits described in the Indenture, including any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

6. TRANSFER AND EXCHANGE; DENOMINATIONS

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of a Security of the series of which this Security is a part is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest, if any, on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of the series of which this Security is a part are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

7. SUCCESSOR OBLIGORS

When a successor assumes all the obligations of its predecessor under the Securities of this series and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

8. TRUSTEE DEALINGS WITH THE COMPANY

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities of this series and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

9. NO RECOURSE AGAINST OTHERS

No stockholder, director, officer, employee, incorporator or Affiliate of the Company shall have any liability for any obligation of the Company under the Securities of this series or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of the Securities of this series by accepting a Security of this series waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities of this series.

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $500,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

in aggregate principal amount of the Outstanding securities of such series may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee,

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $500,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published

R-1

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

In the event of redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

3. DEFEASANCE

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

4. DEFAULTS AND REMEDIES

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to Securities of this series have been cured or waived (other than the non-payment of principal of the Securities of this series which has become due solely by

R-2

reason of such declaration of acceleration) then, and in every such case, the Holders of a majority in aggregate principal amount of the Outstanding securities under the Indenture may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding under the Indenture a direction inconsistent with such request and (e) the Trustee for 90 days after its receipt of such notice and offer of indemnity from the Holder, and request from the Holders, shall have failed to institute any such proceeding. The foregoing shall not apply to certain suits described in the Indenture, including any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of the series of which this Security is a part are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000.

(ii) upon presentation of certificates (accompanied by an Opinion of Counsel, if applicable) required by Article 2 of the Indenture. Upon exchange of this Regulation S Temporary Global Security for one or more Global Securities, the Trustee shall cancel this Regulation S Temporary Global Security.

Terms defined in the Indenture which are not defined herein are used with the meanings assigned to them in the Indenture. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $500,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series are subject to redemption upon not less than 30 or more than 60 days' notice to the Holders of such Securities as provided in the Indenture, at any time, as a whole or in part, at the election of the Company at any time, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series being redeemed or
(ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 37.5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities of this series to the Redemption Date.

"Treasury Yield" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series.

"Comparable Treasury Price" means, with respect to any Redemption Date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day in New York City preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published

R-1

by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the Reference Treasury Dealer Quotation for such Redemption Date.

"Independent Investment Banker" means an investment banking institution of international standing appointed by the Company.

"Reference Treasury Dealer" means a primary U.S. government securities dealer in New York City appointed by the Company.

"Reference Treasury Dealer Quotation" means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day in New York City preceding such Redemption Date).

Notice of redemption pursuant to this paragraph 2 shall be given as provided for in the Indenture not less than 30 days nor more than 60 days prior to the Redemption Date.

If fewer than all the Securities of this series are to be redeemed, selection of Securities of this series for redemption will be made by the Trustee in any manner the Trustee deems fair and appropriate.

Unless the Company defaults in payment of the Redemption Price, from and after the Redemption Date, the Securities of this series or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Securities of this series except the right to receive the Redemption Price thereof.

In the event of redemption of this Security in part only, the Trustee will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

3. DEFEASANCE

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

4. DEFAULTS AND REMEDIES

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration with respect to Securities of this series has been made, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to Securities of this series have been cured or waived (other than the non-payment of principal of the Securities of this series which has become due solely by

R-2

reason of such declaration of acceleration) then, and in every such case, the Holders of a majority in aggregate principal amount of the Outstanding securities of such series may, by written notice to the Company and to the Trustee, rescind and annul such declaration and its consequences on behalf of all of the Holders, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the securities, (b) the Holders of not less than 33% or a majority, as applicable, in principal amount of the Securities at the time Outstanding under the Indenture shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee,
(c) such Holder shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding under the Indenture a direction inconsistent with such request and (e) the Trustee for 90 days after its receipt of such notice and offer of indemnity from the Holder, and request from the Holders shall have failed to institute any such proceeding. The foregoing shall not apply to certain suits described in the Indenture, including any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

5. AMENDMENT AND WAIVER

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of the series of which this Security is a part are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

REGISTRATION RIGHTS AGREEMENT

October 1, 2002

Credit Suisse First Boston Corporation
The other Initial Purchasers Listed on Schedule A hereto c/o Credit Suisse First Boston Corporation Eleven Madison Avenue
New York, New York 10010-3629

Dear Sirs:

MidAmerican Energy Holdings Company, an Iowa corporation (the "COMPANY"), proposes to issue and sell to Credit Suisse First Boston Corporation and the other Initial Purchasers listed on Schedule A hereto (collectively, the "INITIAL PURCHASERS"), upon the terms set forth in a purchase agreement of even date herewith (the "PURCHASE AGREEMENT"), $200,000,000 aggregate principal amount of its 4.625% Senior Notes due October 1, 2007 and $500,000,000 aggregate principal amount of its 5.875% Senior Notes due October 1, 2012 (collectively, the "INITIAL SECURITIES"). The Initial Securities will be issued pursuant to an Indenture, to be dated on or about October 4, 2002, as supplemented by a first supplemental indenture to be entered into thereunder, to be dated on or about October 4, 2002 (together, the "INDENTURE"), between the Company and The Bank of New York, as trustee (the "TRUSTEE"). As an inducement to the Initial Purchasers to enter into the Purchase Agreement, the Company agrees with the Initial Purchasers, for the benefit of the Initial Purchasers and the holders of the Securities (as defined below) (collectively the "HOLDERS"), as follows:

1. Registered Exchange Offer. Unless not permitted by applicable law (after the Company has complied with the ultimate paragraph of this Section 1), the Company shall prepare and file with the Securities and Exchange Commission (the "COMMISSION") a registration statement (the "EXCHANGE OFFER REGISTRATION STATEMENT") on an appropriate form under the Securities Act of 1933, as amended (the "SECURITIES ACT"), with respect to a proposed offer (the "REGISTERED EXCHANGE OFFER") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial Securities, a like aggregate principal amount of debt securities of the Company issued under the Indenture, substantially identical in all material respects to the Initial Securities and registered under the Securities Act (the "EXCHANGE SECURITIES" and, together with the Initial Securities, the "SECURITIES"). The Company shall use its reasonable best efforts to cause the Exchange Offer Registration Statement to become effective under the Securities Act within 270 days (such 270th day being an "EFFECTIVENESS DEADLINE") after the date on which the Initial Purchasers purchase the Initial Securities pursuant to the Purchase Agreement (the "CLOSING DATE") and will keep the Exchange Offer Registration


Statement effective for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such period being called the "EXCHANGE OFFER REGISTRATION PERIOD").

If the Company commences the Registered Exchange Offer, the Company will be entitled to consummate the Registered Exchange Offer 30 days after such commencement (provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer).

Following the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of the Registered Exchange Offer to enable each Holder of Transfer Restricted Securities electing to exchange the Initial Securities for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder's business and has no arrangements or understanding with any person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt without any limitations or restrictions under the Securities Act.

The Company acknowledges that, pursuant to current interpretations by the Commission's staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Initial Securities, acquired for its own account as a result of market making activities or other trading activities, for Exchange Securities (an "EXCHANGING DEALER"), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer" section, and (c) Annex C hereto in the "Plan of Distribution" section of such prospectus in connection with a sale of any such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell Securities (as defined below) acquired in exchange for Initial Securities constituting any portion of an unsold allotment, is required to deliver a prospectus containing the information required by Items 507 or 508, as applicable, of Regulation S-K under the Securities Act in connection with such sale.

The Company shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided, however, that
(i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 120 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 120 days after the consummation of the Registered Exchange Offer.

If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange (the "PRIVATE EXCHANGE") for the Initial Securities held by such Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and substantially identical in all material respects to the Initial Securities (the "PRIVATE EXCHANGE SECURITIES"). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the "SECURITIES".

2

In connection with the Registered Exchange Offer, the Company shall:

(a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(b) keep the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders;

(c) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee;

(d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and

(e) otherwise comply with all applicable laws.

As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall:

(x) accept for exchange all the Initial Securities validly tendered and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange;

(y) deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and

(z) cause the Trustee to authenticate and deliver promptly to each Holder of the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange.

The Indenture will provide that the Exchange Securities will not be subject to the transfer restrictions set forth in the Indenture and that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one another on any matter.

Interest on each Exchange Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no interest has been paid on the Initial Securities, from the date of original issue of the Initial Securities.

Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the consummation of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of its business, (ii) at the time of commencement of the Registered Exchange Offer, such Holder had no arrangements or understanding with any person to participate in the distribution of the Securities or the Exchange Securities within the meaning of the Securities Act,
(iii) such Holder is not an "affiliate," as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making activities or other trading activities and

3

that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.

Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and any supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any Exchange Offer Registration Statement, and any supplement to such prospectus, does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

If following the date hereof there has been announced a change in Commission policy with respect to exchange offers that in the reasonable opinion of counsel to the Company raises a substantial question as to whether the Registered Exchange Offer is permitted by applicable federal law, the Company will seek a no-action letter or other favorable decision from the Commission allowing the Company to consummate the Registered Exchange Offer. The Company will pursue the issuance of such a decision to the Commission staff level. In connection with the foregoing, the Company will take all such other actions as may be requested by the Commission or otherwise reasonably required in connection with the issuance of such decision, including without limitation (i) participating in telephonic conferences with the Commission, (ii) delivering to the Commission staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that the Registered Exchange Offer should be permitted and (iii) diligently pursuing a resolution (which need not be favorable) by the Commission staff.

2. Shelf Registration. If, (i) because of any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated by the date that is 40 days after the date on which the Exchange Offer Registration Statement is declared effective (such 40th day being the "CONSUMMATION DEADLINE"), (iii) any Initial Purchaser so requests with respect to the Initial Securities (or the Private Exchange Securities) not eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange and any such Holder so requests for any reason other than the failure by such Holder to make a timely and valid tender in accordance with the Registered Exchange Offer, the Company shall take the following actions (the date on which any of the conditions described in the foregoing clauses (i) through (iv) occur, including in the case of clauses (iii) or (iv) the receipt of the required notice, being a "TRIGGER DATE"):

(a) The Company shall as promptly as practicable prepare and file with the Commission and thereafter use its reasonable best efforts to cause to be declared effective not later than the latter to occur of the date that is (i) 150 days after the Trigger Date and (ii) 270 days after the Closing Date (such 150th or 270th day, as the case may be, being an "EFFECTIVENESS DEADLINE"), a registration statement (the "SHELF REGISTRATION STATEMENT" and, together with the Exchange Offer Registration Statement, a "REGISTRATION STATEMENT") on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the "SHELF REGISTRATION"); provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities

4

held by it covered by the Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder.

(b) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the Closing Date or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof) (such applicable period being called the "SHELF REGISTRATION PERIOD").

(c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission promulgated thereunder and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

3. Registration Procedures. In connection with any Shelf Registration Statement contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply:

(a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering of the Initial Securities) is participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose not later than five business days after delivery of such documents to such Initial Purchaser; (ii) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer" section and in Annex C hereto in the "Plan of Distribution" section of the prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the letter of transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by an Initial Purchaser, include the information required by Items 507 or 508, as applicable, of Regulation S-K under the Securities Act in the prospectus forming a part of the Exchange Offer Registration Statement; (iv) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution," reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a "PARTICIPATING BROKER-DEALER"), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include the names of the Holders who propose to sell Securities pursuant to the Shelf Registration Statement as selling securityholders.

5

(b) The Company shall give written notice to the Initial Purchasers, the Holders of the Securities and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made):

(i) when the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective;

(ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information;

(iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose;

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose of which the Company has knowledge; and

(v) of the happening of any event that requires the Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading.

(c) The Company shall make every reasonable effort to obtain the withdrawal, at the earliest possible time, of any order suspending the effectiveness of the Registration Statement.

(d) The Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference).

(e) The Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and to any other Holder who so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such Holder requests, all exhibits thereto (including those incorporated by reference).

(f) The Company shall, during the Shelf Registration Period, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use in accordance with applicable law of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement.

6

(g) The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use in accordance with applicable law of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer Registration Statement.

(h) Prior to any public offering of the Securities pursuant to any Registration Statement, the Company shall cooperate with the Holders of the Securities included therein and their Special Counsel (as defined in paragraph (p) below) in connection with the registration or qualification of the Securities for offer and sale under the securities or "blue sky" laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject.

(i) The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement.

(j) Upon the occurrence of any event contemplated by paragraphs
(ii) through (v) of Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchasers, the Holders of the Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers, the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j).

(k) Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company.

7

(l) The Company will use its reasonable best efforts to comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of
Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company's first fiscal quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period.

(m) The Company shall use its reasonable best efforts to cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and, in connection therewith, cooperate with the Trustee under the Indenture and the Holders of Securities to effect such changes to the Indenture as may be required for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture.

(n) The Company may require each Holder of Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that fails to furnish such information within a reasonable time after receiving such request.

(o) The Company shall enter into such customary agreements
(including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder of the Securities shall reasonably request in order to facilitate the disposition of the Securities pursuant to any Shelf Registration.

(p) In the case of any Shelf Registration, the Company shall (i) make available at reasonable times and upon reasonable notice for inspection by a representative of the Holders of a majority in aggregate principal amount of the Securities being sold, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company's officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders of the Securities or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described herein (which counsel shall be Latham & Watkins or another law firm reasonably acceptable to the Company, such counsel being referred to herein as the "SPECIAL COUNSEL"); provided, further, however, that, as a condition to supplying such information, the Company shall receive an agreement in writing from such Special Counsel agreeing that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such information shall be kept confidential by such Special Counsel and any other person entitled to receive such information pursuant to this paragraph (p) unless (w) disclosure of such information is required pursuant to applicable law or by court or administrative order, (x) disclosure of such information is, in the reasonable opinion of counsel to the Company, necessary to avoid or correct a misstatement or omission of a material fact in any Registration Statement, prospectus or any

8

supplement or post-effective amendment thereto or disclosure is otherwise required by law, (y) such information becomes generally available to the public other than as a result of a disclosure by such counsel or any other person entitled to receive such information pursuant to this paragraph (p) in violation of this proviso or (z) such information is approved for release by the Company in writing.

(q) In the case of any Shelf Registration, the Company, if requested by any Holder of Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the Company and its "significant subsidiaries" (as defined in Rule 1-02(w) of Regulation S-X); the qualification of the Company and its significant subsidiaries to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company and its significant subsidiaries; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and, as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein, if applicable, of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable Securities; and (iii) its independent public accountants and the independent public accountants with respect to any other entity, if any, for which financial information is provided in the Shelf Registration Statement to provide to the selling Holders of the applicable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72.

(r) In the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Section 6(c)-(e) of the Purchase Agreement with such changes as are customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants and the independent public accountants with respect to any other entity, if any, for which financial information is provided in the Registration Statement to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the substance thereof as set forth in
Section 6(a) of the Purchase Agreement, with appropriate date changes.

(s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the Exchange Securities or the Private Exchange Securities, as the

9

case may be, the Company shall mark, or caused to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied.

(t) The Company will use its reasonable best efforts to cause the Securities covered by any Registration Statement to continue to be rated by the rating agencies that initially rated the Securities during the period that any such Registration Statement is required hereunder to remain effective (it being acknowledged, however, that the foregoing shall not be deemed to require the Company to maintain the rating of such Securities at the rating initially given to the Securities).

(u) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or "assist in the distribution" (within the meaning of the Conduct Rules (the "RULES") of the National Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by
(i) if such Rules, including Rule 2720, shall so require, engaging a "qualified independent underwriter" (as defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and (iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules.

(v) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities covered by a Registration Statement contemplated hereby.

(w) Notwithstanding any other provision hereof, the Company may postpone or suspend the filing or the effectiveness of a Registration Statement (or any amendments or supplements thereto) if (i) such action is required by applicable law or (ii) such action is taken by the Company in good faith and for valid business reasons (not including the avoidance of the Company's obligations hereunder), including the acquisition or divestiture of assets, other pending corporate developments, public filings with the Commission or other similar events, so long as the Company promptly thereafter complies with the requirements of Section 3(j) hereof, if applicable. Notwithstanding the occurrence of any event referred to in the immediately preceding sentence (each such occurrence, a "SUSPENSION"), no such Suspension shall suspend, postpone or in any other manner affect the running of the time period after which a Registration Default shall be deemed to occur and, if the filing or effectiveness of any such Registration Statement is postponed or suspended as a result of a Suspension, a Registration Default shall nonetheless exist if all other requirements required for the occurrence of a Registration Default shall then be satisfied, and the provisions of
Section 6 hereof requiring the accrual and payment of Additional Interest, as set forth in such Section, on the Securities shall be payable.

4. Registration Expenses.

(a) All expenses incident to the Company's performance of and compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement is ever filed or becomes effective, including without limitation;

(i) all registration and filing fees and expenses;

10

(ii) all fees and expenses of compliance with federal securities and state "blue sky" or securities laws;

(iii) all expenses of printing (including printing certificates for the Securities to be issued in the Registered Exchange Offer and the Private Exchange and printing of Prospectuses), messenger and delivery services and telephone;

(iv) all fees and disbursements of counsel for the Company; and

(v) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance).

The Company will bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any person, including special experts, retained by the Company.

(b) In connection with any Registration Statement required by this Agreement, the Company will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities who are tendering Initial Securities in the Registered Exchange Offer and/or selling or reselling Securities pursuant to the "Plan of Distribution" contained in the Exchange Offer Registration Statement or the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of the Special Counsel.

5. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Holder of the Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any Participating Broker-Dealer and such controlling persons are referred to collectively as the "INDEMNIFIED PARTIES") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and
(ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from

11

whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Holder or Participating Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final prospectus if the Company had previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders.

(b) Each Holder of the Securities, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons.

(c) Promptly after receipt by an indemnified party under this
Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; provided, however, that the omission so to notify the indemnifying party (i) shall not relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that the indemnified party shall have the right to employ counsel to represent the indemnified party and their respective controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 5 if the employment of such counsel shall have been authorized in writing by the indemnifying party in

12

connection with the defense of such action, if in the written opinion of counsel to either the indemnifying party or the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them or the indemnifying party shall have failed to employ counsel within a reasonable period of time, and in that event the fees and expenses of one firm of separate counsel (in addition to the fees and expenses of one firm of local counsel in each applicable jurisdiction) shall be paid by the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders of the Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company.

(e) The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party.

6. Additional Interest Under Certain Circumstances.

(a) Additional interest (the "ADDITIONAL INTEREST") with respect to each Transfer Restricted Security shall be assessed as follows if either of the following events occur (each such event in clauses (i) and (ii) below being herein called an "REGISTRATION DEFAULT"):

13

(i) any Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline; or

(ii) on and after the applicable Effectiveness Deadline (plus an additional 30 days in respect of the Exchange Offer Registration Statement), any Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified herein because
(1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (2) it shall be necessary to amend such Registration Statement or supplement the related prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder or (3) of a Suspension by the Company in accordance with Section 3(w) hereof.

Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission.

Additional Interest shall accrue on each Transfer Restricted Security over and above the interest set forth in the title of such Transfer Restricted Security from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have ceased to be continuing, at a rate of 0.50% per annum (the "ADDITIONAL INTEREST RATE").

(b) A Registration Default referred to in Section 6(a)(ii) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the date of such Registration Default until such Registration Default ceases.

(c) Notwithstanding the foregoing, the Company shall not be required to pay the Additional Interest required pursuant to paragraph
(a) above to a Holder of Transfer Restricted Securities if the applicable Registration Default arises by reason of the failure of such Holder to provide such information as (i) the Company may reasonably request, with reasonable prior written notice, for use in the Shelf Registration Statement or any prospectus included therein to the extent the Company reasonably determines that such information is required to be included therein by applicable law, (ii) the NASD or the Commission may request in connection with such Shelf Registration Statement or (iii) is required to comply with the agreements of such Holder contained in Section 3(a) to the extent compliance thereof is necessary for the Shelf Registration Statement to be declared effective.

14

(d) Any amounts of Additional Interest due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest Rate by the principal amount of the Securities and further multiplied by a fraction, the numerator of which is the number of days such Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360.

(e) "TRANSFER RESTRICTED SECURITIES" means each Security until
(i) the date on which such Security has been exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange Security, the date on which such Exchange Security is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or
(iv) the date on which such Security is distributed to the public pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act.

7. Rules 144 and 144A. The Company agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any Holder, to such Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

8. Underwritten Registrations. If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, subject to the proviso in Section 3(o) hereof, the investment banker or investment bankers and manager or managers that will administer the offering ("MANAGING UNDERWRITERS") will be selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering and will be reasonably acceptable to the Company.

No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person's Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

9. Miscellaneous.

(a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 1 and 2 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Sections 1 and 2 hereof. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

15

(b) No Inconsistent Agreements. The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company hereby represents that the rights granted to the Holders hereunder do not conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof.

(c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement, waiver or consents; provided, however, that, with respect to any matter that directly or indirectly adversely affects the rights of any Holder of Transfer Restricted Securities occurring within the period in which any Registration Statement is effective for such Holder, the Company shall obtain the written consent of each such Holder against which such amendment, modification, supplement, waiver, consent or departure is to be effective. Notwithstanding the foregoing (except of the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of any Holder of Securities whose Securities are being sold or exchanged pursuant to a Registration Statement and that does not directly or indirectly adversely affect the rights of any other Holder of Securities may be given by Holders of at least a majority in aggregate principal amount of the Securities being sold or exchanged by such holders pursuant to such Registration Statement; provided, however, that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence. Without the consent of the Holder of each Security, however, no modification may change the provisions relating to the payment of Additional Interest.

(d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery:

(k) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

17

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the several Initial Purchasers and the Company in accordance with its terms.

Very truly yours,

This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 120 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for use in connection with any such resale.

See "Plan of Distribution."

ANNEX C

PLAN OF DISTRIBUTION

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 120 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until , 200 , all dealers effecting transactions in the Exchange Securities may be required to deliver a prospectus.(1)

The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Securities may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

For a period of 120 days after the Expiration Date the Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal.

By acceptance of a Certificate, each transferee shall be deemed to have agreed to be bound by this Declaration and the documents incorporated by reference herein.

SECTION 9.3. DEEMED TRUST SECURITY HOLDERS

The Trustees may treat the Person in whose name any Certificate shall be registered on the books and records of the Trust as the sole holder of such Certificate and of the Trust Securities represented by such Certificate for purposes of receiving Distributions and for all

-28-

other purposes whatsoever and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Certificate or in the Trust Securities represented by such Certificate on the part of any Person, whether or not the Trust shall have actual or other notice thereof.

SECTION 9.4. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES

If (a) any mutilated Certificates should be surrendered to the Regular Trustees, or if the Regular Trustees shall have received evidence to their satisfaction of the destruction, loss or theft of any Certificate; and (b) there shall be delivered to the Regular Trustees such security or indemnity as may be required by them to keep each of them harmless, then in the absence of notice that such Certificate shall have been acquired by a bona fide purchaser, any two Regular Trustees on behalf of the Trust shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like denomination. In connection with the issuance of any new Certificate under this Section 9.4, the Regular Trustees may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

-29-

SECTION 10.2. EXCULPATION

(a) No Indemnified Person shall be liable, responsible or accountable in damages or otherwise to the Trust or any Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in good faith on behalf of the Trust and in a manner such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by this Declaration or by law, except that an Indemnified Person shall be liable for any such loss, damage or claim incurred by reason of such Indemnified Person's gross negligence (or, in the case of the Property Trustee, negligence) or willful misconduct with respect to such acts or omissions.

The provisions of this Declaration, to the extent that they restrict the duties and liabilities of an Indemnified Person otherwise existing at law or in equity (other than the duties imposed on the Property Trustee under the Trust Indenture Act, if any), are agreed by the parties hereto to replace such other duties and liabilities of such Indemnified Person.

(b) Unless otherwise expressly provided herein:

In the absence of bad faith by the Indemnified Person, the resolution, action or term so made, taken or provided by this Indemnified Person shall not constitute a breach of this Declaration or any other agreement contemplated herein or of any duty or obligation of the Indemnified Person at law or in equity or otherwise.

-30-

(c) Whenever in this Declaration an Indemnified Person is permitted or required to make a decision:

(i) in its "discretion" or under a grant of similar authority, the Indemnified Person shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust or any other Person; or

(ii) in its "good faith" or under another express standard, the Indemnified Person shall act under such express standard and shall not be subject to any other or different standard imposed by this Declaration or by applicable law.

(b) To the fullest extent permitted by applicable law, expenses (including legal fees) incurred by an Indemnified Person in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Sponsor prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined that the Indemnified Person is not entitled to be indemnified as authorized in Section
10.4(a). The indemnification shall survive the termination of this Declaration or the earlier removal or resignation of any of the Trustees or the Property Trustee.

SECTION 10.5. OUTSIDE BUSINESSES

Any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Trust, and the Trust and the Holders of Trust Securities shall have no rights by virtue of this Declaration in and to such independent ventures or the income or profits derived therefrom and the pursuit of any such venture, even if competitive with the business of the Trust, shall not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware Trustee or the Property Trustee shall be obligated to present any particular investment or other opportunity to the Trust even if such opportunity is of a character that, if presented to the Trust, could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee shall have the right to take for its own account (individually or as a partner or fiduciary) or to recommend to others

-31-

ARTICLE XI.

ACCOUNTING

SECTION 11.1. FISCAL YEAR

The fiscal year ("FISCAL YEAR") of the Trust shall be the calendar year, or such other year as is required by the Code.

SECTION 11.2. CERTAIN ACCOUNTING MATTERS

(a) At all times during the existence of the Trust, the Regular Trustees shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail, each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently applied. The Trust shall use the accrual method of accounting for United States federal income tax purposes. The books of account and the records of the Trust shall be examined by and reported upon as of the end of each Fiscal Year by a firm of independent certified public accountants selected by the Regular Trustees.

(b) The Regular Trustees shall cause to be prepared and delivered to each of the Holders of Trust Securities, within 90 days after the end of each Fiscal Year of the Trust, annual financial statements of the Trust, including a balance sheet of the Trust as of the end of such Fiscal Year, and the related statements of income or loss.

(c) The Regular Trustees shall cause to be duly prepared and delivered to each of the Holders of Trust Securities any United States federal income tax information statement required by the Code, containing such information with regard to the Trust Securities held by each Holder as is required by the Code and the Treasury Regulations, and any comparable statements required to be provided under the law of any other taxing jurisdiction. Notwithstanding any right under the Code or other law to deliver any such statement at a later date, the Regular Trustees shall endeavor to deliver all such statements within 30 days after the end of each Fiscal Year of the Trust.

(d) The Regular Trustees shall cause to be duly prepared and filed with the appropriate taxing authority an annual United States federal income tax return Form 1041 (or any successor form) or such other form required by United States federal income tax law, and any other tax returns or reports required to be filed by the Regular Trustees on behalf of the Trust with any state or local taxing authority.

-32-

SECTION 11.3. BANKING

The Trust shall maintain one or more bank accounts in the name and for the sole benefit of the Trust; provided, however, that all payments of funds in respect of the Subordinated Debentures held by the Property Trustee shall be made directly to the Property Trustee Account and no other funds of the Trust shall be deposited in the Property Trustee Account. The sole signatories for such accounts shall be designated by the Regular Trustees; provided, however, that the Property Trustee shall designate the sole signatories for the Property Trustee Account.

SECTION 11.4. WITHHOLDING

The Trust and the Regular Trustees shall comply with all withholding requirements under United States federal, state and local law. The Trust shall request, and the Holders shall provide to the Trust, such forms or certificates as are necessary to establish an exemption from withholding with respect to each Holder, and any representations and forms as shall reasonably be requested by the Trust to assist it in determining the extent of, and in fulfilling, its withholding obligations. The Regular Trustees shall file required forms with applicable jurisdictions and, unless an exemption from withholding is properly established by a Holder, shall remit amounts withheld with respect to the Holder to applicable jurisdictions. To the extent that the Trust is required to withhold and pay over any amounts to any authority with respect to distributions or allocations to any Holder, the amount withheld shall be deemed to be a distribution in the amount of the withholding to the Holder. In the event of any claimed over withholding, Holders shall be limited to an action against the applicable jurisdiction. If the amount required to be withheld was not withheld from actual Distributions made to any Holder, the Trust may reduce subsequent Distributions to such Holder by the amount of such withholding.

ARTICLE XII.

(iii) no amendment shall be made, and any such purported amendment shall be void and ineffective, to the extent the result of such amendment would be to:

(A) cause the Trust to fail to continue to be classified for purposes of United States federal income taxation as a grantor trust and each Holder of the Trust Securities not to be treated as owning an undivided beneficial interest in the Subordinated Debentures, as evidenced by an Opinion of Counsel to the effect that such amendment shall not result in the foregoing;

(B) reduce or otherwise adversely affect the powers of the Property Trustee in contravention of the Trust Indenture Act; or

(C) cause the Trust to be deemed to be an Investment Company required to be registered under the Investment Company Act;

(iv) at such time after the Trust has issued any Trust Securities that remain outstanding, any amendment that would adversely affect the rights, privileges or preferences of any Holder of the Trust Securities may be effected only with such additional requirements as may be set forth in the terms of such Trust Securities;

(v) Section 9.1(c) and this Section 12.1 shall not be amended without the consent of all of the Holders of the Trust Securities;

-34-

(c) Notwithstanding any other provision of this Declaration, neither the Property Trustee nor the Delaware Trustee shall be required to enter into any amendment to this Declaration which affects its own rights, duties or immunities under this Declaration:

SECTION 12.2. MEETINGS OF THE HOLDERS OF TRUST SECURITIES; ACTION BY WRITTEN CONSENT

(a) Meetings of the Holders of any class of Trust Securities may be called at any time by the Regular Trustees (or as provided in the terms of the Trust Securities) to consider and act on any matter on which Holders of such class of Trust Securities are entitled to act under the terms of this Declaration or the terms of the Trust Securities. The Regular Trustees shall call a meeting of the Holders of such class if directed to do so by the Holders of at least 10% in liquidation amount of such class of Trust Securities. Such direction shall be given by delivering to the Regular Trustees one or more calls in a writing stating that the signing Holders of Trust Securities wish to call a meeting and indicating the general or specific purpose for which the meeting is to be called.

Any action that may be taken at a meeting of the Holders of Trust Securities may be taken without a meeting if a consent in writing setting forth the action so taken is signed by the Holders of Trust Securities owning not less than the minimum amount of Trust Securities in liquidation amount that would be necessary to authorize or take such action at a meeting at which all Holders of Trust Securities having a right to vote thereon were present and voting. Prompt notice of the taking of action without a meeting shall be given to the Holders of Trust Securities entitled to vote who have not consented in writing. The Regular Trustees may specify that any written ballot submitted to a Holder for the purpose of taking any action without a meeting shall be returned to the Trust within the time specified by the Regular Trustees;

(ii) each Holder of a Trust Security may authorize any Person to act for it by proxy on all matters in which a Holder of Trust Securities is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting. No proxy shall be valid

-35-

after the expiration of 11 months from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the Holder of Trust Securities executing it. Except as otherwise provided herein, all matters relating to the giving, voting or validity of proxies shall be governed by the General Corporation Law of the State of Delaware relating to proxies, and judicial interpretations thereunder, as if the Trust were a Delaware corporation and the Holders of the Trust Securities were stockholders of a Delaware corporation;

(iii) each meeting of the Holders of the Trust Securities shall be conducted by the Regular Trustees or by such other Person that the Regular Trustees may designate; and

(iv) unless the Business Trust Act, this Declaration, the terms of the Trust Securities, or the Trust Indenture Act otherwise provides, the Regular Trustees, in their sole discretion, shall establish all other provisions relating to meetings of Holders of Trust Securities, including notice of the time, place or purpose of any meeting at which any matter is to be voted on by any Holders of Trust Securities, waiver of any such notice, action by consent without a meeting, the establishment of a record date, quorum requirements, voting in person or by proxy or any other matter with respect to the exercise of any such right to vote.

EXHIBIT A

TERMS OF
11% TRUST ISSUED PREFERRED SECURITIES
11% TRUST ISSUED COMMON SECURITIES

Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust, dated as of August 16, 2002 (as amended from time to time, the "DECLARATION"), the designation, rights, privileges, restrictions, preferences and other terms and provisions of the Preferred Securities and the Common Securities are set out below (each capitalized term used but not defined herein has the meaning set forth in the Declaration). The Trust may issue one or more series of Preferred Securities and one or more series of Common Securities, provided, however, that the original principal amount of each series (other than the final series) of Preferred Securities must be at least $50,000,000.

1. DESIGNATION AND NUMBER.

(a) PREFERRED SECURITIES. Up to 38,000,000 Preferred Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Nine Hundred Fifty Million Dollars ($950,000,000) and a liquidation amount with respect to the assets of the Trust of $25 per Preferred Security, are hereby designated for the purposes of identification only as "11% Trust Issued Preferred Securities" (the "PREFERRED SECURITIES"). The Certificates evidencing the Preferred Securities shall be substantially in the form attached hereto as Annex I, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.

(b) COMMON SECURITIES. Up to 11,175,258 Common Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Twenty Nine Million Three Hundred Eighty One Thousand Four Hundred Fifty Dollars ($29,381,450) and a liquidation amount with respect to the assets of the Trust of $25 per Common Security, are hereby designated for the purposes of identification only as "11% Trust Issued Common Securities" (the "COMMON SECURITIES"). The Certificates evidencing the Common Securities shall be substantially in the form attached hereto as Annex II, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.

2. DISTRIBUTIONS.

(a) Distributions payable on each Trust Security will be fixed at a rate per annum of 11% (the "COUPON Rate") of the stated liquidation amount of $25 per Trust Security, such rate being the rate of interest payable on the Subordinated Debentures to be held by the Property Trustee. Distributions in arrears for more than one semi-annual period will bear interest thereon compounded semi-annually at the Coupon Rate (to the extent permitted by applicable law). The term "DISTRIBUTIONS" as used herein includes such cash distributions and any such interest payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Subordinated Debentures held by the Property Trustee. The amount of Distributions payable for any period will be computed for any full semi-annual Distribution


period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full semi-annual Distribution period for which Distributions are computed, Distributions will be computed on the basis of the actual number of days elapsed per 30-day month.

(b) Distributions on each series of Trust Securities will be cumulative, will accumulate from the date of original issuance of the Trust Securities of such series (the "SERIES ISSUE DATE"), and will be payable semi-annually in arrears, on February 28 and August 31 of each year, commencing on the first such date following the date one month following the Series Issue Date, except as otherwise described below. The Sponsor has the right under the Indenture to defer payments of interest by extending the interest payment period from time to time and for varying lengths of time on the Subordinated Debentures for a period not exceeding 10 consecutive semi-annual periods (each, an "EXTENSION PERIOD") and during such Extension Period, Distributions will also be deferred. Despite such deferral, semi-annual Distributions will continue to accumulate with interest thereon (to the extent permitted by applicable law) at an annual rate of thirteen percent (13%) per annum compounded semi-annually during any such Extension Period. Prior to the termination of any such Extension Period, the Sponsor may further extend such Extension Period; provided that such Extension Period together with all such previous and further extensions thereof may not exceed 10 consecutive semi-annual periods. Payments of accumulated Distributions will be payable to Holders as they appear on the books and records of the Trust on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Sponsor may commence a new Extension Period, subject to the above requirements.

(c) Distributions on the Trust Securities will be payable to the Holders thereof as they appear on the books and records of the Trust on the relevant record dates. Distributions payable on any Trust Securities that are not punctually paid on any Distribution payment date, as a result of the Sponsor having failed to make a payment under the Subordinated Debentures, will cease to be payable to the Person in whose name such Trust Securities are registered on the relevant record date, and such Distribution will instead be payable to the Person in whose name such Trust Securities are registered on the special record date or other specified date determined in accordance with the Indenture. If any date on which Distributions are payable on the Trust Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date.

(d) In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed Pro Rata (as defined herein) among the Holders of the Trust Securities.

3. LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

In the event of any voluntary or involuntary dissolution of the Trust, the Holders of the Trust Securities on the date of the dissolution will be entitled to receive out of the assets of the Trust available for distribution to Holders of Trust Securities after satisfaction of liabilities to creditors of the Trust, if any (including, without limitation, by paying or making reasonable

A-2

provisions to pay all claims and obligations of the Trust in accordance with
Section 3808(e) of the Business Trust Act), an amount equal to the aggregate of the stated liquidation amount of $25 per Trust Security plus accumulated and unpaid Distributions thereon (including interest thereon) to the date of payment (such amount being the "LIQUIDATION DISTRIBUTION"), unless, in connection with such dissolution, after satisfaction of liabilities to creditors of the Trust (including, without limitation, by paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act) Subordinated Debentures in an aggregate principal amount equal to the aggregate stated liquidation amount of such Trust Securities and of like tenor shall be distributed on a Pro Rata basis to the Holders of the Trust Securities in exchange for such Trust Securities.

If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Trust Securities shall be paid on a Pro Rata basis. The holders of the Common Securities will be entitled to receive distributions upon any such dissolution Pro Rata with the holders of the Preferred Securities, except that if an Event of Default has occurred and is continuing, the Preferred Securities shall have a preference over the Common Securities with regard to such distributions.

On and from the date fixed by the Regular Trustees for any distribution of Subordinated Debentures: (i) the Trust Securities will no longer be deemed to be outstanding, (ii) the Depositary, as the Holder of the Preferred Securities, will receive a registered global certificate representing the Subordinated Debentures to be delivered upon such distribution, and (iii) any certificates representing Trust Securities not held by the Depositary or its nominee (or any successor depositary or its nominee), will be deemed to represent beneficial interests in the Subordinated Debentures having an aggregate principal amount equal to the aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accumulated and unpaid Distributions on, such Trust Securities until such certificates are presented to the Sponsor or its agent for transfer or reissue.

4. REDEMPTION; REDEMPTION/DISTRIBUTION PROCEDURES.

(a) Upon the repayment of a series of Subordinated Debentures (a "DEBENTURE SERIES"), whether at the Maturity Date or upon redemption thereof, in whole or in part, the proceeds from such repayment or redemption shall be simultaneously applied to redeem the series of Trust Securities used to purchase such Debenture Series, having an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Debentures so repaid or redeemed at a redemption price of $25 per Trust Security plus an amount equal to accumulated and unpaid Distributions thereon at the date of the redemption, payable in cash (the "REDEMPTION PRICE"). Applicable Holders will be given not less than 30 nor more than 60 days notice of such redemption.

(b) If fewer than all the outstanding Trust Securities in a series are to be so redeemed, the applicable Preferred Securities and the applicable Common Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed will be as described in Section 4(d)(ii) below.

A-3

(c) The Trust may not redeem fewer than all the outstanding Trust Securities unless all accumulated and unpaid Distributions have been paid on all Trust Securities for all semi-annual Distribution periods terminating on or before the date of redemption.

(d) (i) Notice of any redemption of a series of Trust Securities, or notice of distribution of Subordinated Debentures in exchange for the Trust Securities (a "REDEMPTION/DISTRIBUTION NOTICE"), will be given by the Regular Trustees on behalf of the Trust by mail to each Holder of Trust Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days before the date fixed for redemption or exchange thereof which, in the case of a redemption, will be the date fixed for redemption of the Subordinated Debentures. For purposes of the calculation of the date of redemption or exchange and the dates on which notices are given pursuant to this Section 4(d)(i), a Redemption/Distribution Notice shall be deemed to be given on the day such notice is first mailed by first-class mail, postage prepaid, to Holders of Trust Securities. Each Redemption/Distribution Notice shall be addressed to the Holders of Trust Securities at the address of each such Holder appearing in the books and records of the Trust. No defect in the Redemption/Distribution Notice or in the mailing of either thereof with respect to any Holder shall affect the validity of the redemption or exchange proceedings with respect to any other Holder.

(ii) In the event that fewer than all the outstanding Trust Securities are to be redeemed, the Trust Securities to be redeemed shall be redeemed Pro Rata.

(iii) If Trust Securities are to be redeemed and the Regular Trustees on behalf of the Trust give a Redemption/Distribution Notice, which notice may only be issued if the Subordinated Debentures are redeemed as set out in this Section 4 (which notice will be irrevocable), then with respect to Preferred Securities and Common Securities, provided that the Sponsor has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Debentures, then the Property Trustee will pay the relevant Redemption Price to the Holders of such Trust Securities by check mailed to the address of the relevant Holder appearing on the books and records of the Trust on the redemption date upon surrender of their Certificates evidencing such Preferred Securities and such Common Securities. If a Redemption/Distribution Notice shall have been given and funds deposited as required, then immediately prior to the close of business on the date of such deposit, or on the redemption date, as applicable, Distributions will cease to accumulate on the Trust Securities so called for redemption and all rights of Holders of such Trust Securities so called for redemption will cease, except the right of the Holders of such Trust Securities to receive the Redemption Price, but without interest on such Redemption Price. Neither the Regular Trustees nor the Trust shall be required to register or cause to be registered the transfer of any Trust Securities that have been so called for redemption. If any date fixed for redemption of Trust Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Redemption Price in respect of any Trust Securities is improperly withheld or refused and not paid either by the Property Trustee or by the Sponsor as guarantor pursuant to the Preferred Securities Guarantee or the Common Securities Guarantee, as the case may be, Distributions on such Trust Securities

A-4

will continue to accumulate from the original redemption date to the actual date of payment, in which case the actual payment date will be considered the date fixed for redemption for purpose of calculating the Redemption Price.

(iv) Redemption/Distribution Notices shall be sent by the Regular Trustees on behalf of the Trust to the Holder.

(v) Subject to the foregoing and applicable law (including, without limitation, United States federal securities laws), provided the acquirer is not the Holder of the Common Securities or the obligor under the Indenture, the Sponsor or any of its subsidiaries may at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement.

5. VOTING RIGHTS - PREFERRED SECURITIES.

(a) Except as provided under Sections 5(b) and 6 and as otherwise required by law, the Preferred Securities Guarantee and the Declaration, the Holders of the Preferred Securities will have no voting rights.

(b) Subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Preferred Securities, voting as a class may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including
(i) directing the time, method, place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee with respect to the Subordinated Debentures,
(ii) waiving any past default and its consequences that is waivable under
Section 4.13 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable, provided, however, that, where a consent under the Indenture would require the consent or act of all of the holders of Subordinated Debentures affected thereby, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Preferred Securities. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration or the Subordinated Debentures, any Holder of Preferred Securities may institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration or the Subordinated Debentures without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Preferred Securities may directly

A-5

institute a proceeding for enforcement of payment to such Holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such Holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Preferred Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Preferred Securities in connection with such direct action. Any approval or direction of Holders of Preferred Securities may be given at a separate meeting of Holders of Preferred Securities convened for such purpose, at a meeting of all the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Preferred Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which the written consent is sought and (iii) instructions for the delivery of proxies or consents.

No vote or consent of the Holders of the Preferred Securities will be required for the Trust to redeem and cancel Preferred Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

Notwithstanding that Holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Sponsor or any Affiliate of the Sponsor (other than Berkshire Hathaway Inc. or any other Permitted Holder) shall not be entitled to vote or consent and shall, for purposes of such vote or consent, be treated as if they were not outstanding.

6. VOTING RIGHTS - COMMON SECURITIES.

(a) Except as provided under Sections 6(b) and 6(c), and as otherwise required by law and the Declaration, the Holders of the Common Securities will have no voting rights.

(b) The Holders of the Common Securities are entitled, in accordance with Article V of the Declaration, to vote to appoint, remove or replace any Trustee or to increase or decrease the number of Trustees.

(c) Subject to Section 2.6 of the Declaration, only after an Event of Default with respect to the Preferred Securities has been cured, waived or otherwise eliminated and subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Common Securities, voting separately as a class, may direct the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred on the Property Trustee with respect to the Subordinated Debentures,
(ii) waiving any past default and its consequences that is waivable under
Section 4.13 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable,

A-6

provided, however, that, where a consent or action under the Indenture would require the consent or act of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Common Securities. Pursuant to this
Section 6(c), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Common Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Common Securities under this paragraph unless the Property Trustee has obtained, at the expense of the Holders of the Common Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration and the Subordinated Debentures, any Holder of Common Securities may after written request to the Property Trustee to enforce such rights, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration and the Subordinated Debentures, without first instituting a legal proceeding against the Property Trustee or any other person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Common Securities may directly institute a proceeding for enforcement of payment to such holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Common Securities of such holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Common Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Common Securities in connection with such direct action.

Any approval or direction of Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purpose, at a meeting of all of the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Common Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. No vote or consent of the Holders of the Common Securities will be required for the Trust to redeem and cancel Common Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

7. AMENDMENTS TO DECLARATION AND INDENTURE.

(a) If any proposed amendment to the Declaration provides for, or the Regular Trustees otherwise propose to effect (i) any action that would adversely affect the powers, preferences or special rights of the Trust Securities, whether by way of amendment to the

A-7

Declaration or otherwise, or (ii) the involuntary or voluntary liquidation, dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Trust Securities as a class, will be entitled to vote on such amendment or proposal (but not on any other amendment or proposal) and such amendment or proposal shall not be effective except with the approval of the Holders of at least 66-2/3% in liquidation amount of the Trust Securities, voting together as a single class; provided that a reduction of the aggregate liquidation amount or the Distribution rate, a change in the payment dates or maturities of the Preferred Securities or a reduction in the percentage in liquidation amount of outstanding Preferred Securities, the consent of the Holders of which is required for an amendment to the Declaration shall not be permitted without the consent of each Holder of the Preferred Securities. In the event any amendment or proposal referred to in clause (i) above would adversely affect only the Preferred Securities or only the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of 66-2/3% in liquidation amount of such class of Trust Securities.

(b) In the event the consent of the Property Trustee, as the holder of the Subordinated Debentures, the Preferred Securities Guarantee and the Common Securities Guarantee is required under the Indenture with respect to any amendment, modification, waiver or termination of the Indenture, the Subordinated Debentures, the Preferred Securities Guarantee or the Common Securities Guarantee, the Property Trustee shall request the direction of the Holders of the Trust Securities with respect to such amendment, modification, waiver or termination and shall vote with respect to such amendment, modification, waiver or termination as directed by a Majority in liquidation amount of the Trust Securities voting together as a single class; provided, however, that where a consent under the Indenture would require the consent of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent at the direction of all of the Holders of the Trust Securities; provided, further, that the Property Trustee shall not take any action in accordance with the directions of the Holders of the Trust Securities under this Section 6(b) unless the Property Trustee has obtained, at the expense of the Holders of the Trust Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action.

8. PRO RATA.

A reference to any payment, distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder of applicable Trust Securities according to the aggregate liquidation amount of such Trust Securities held by the relevant Holder in relation to the aggregate liquidation amount of all applicable Trust Securities outstanding unless, in relation to a payment, an Event of Default under the Indenture has occurred and is continuing, in which case any funds available to make such payment shall be paid first to each Holder of the applicable Preferred Securities pro rata according to the aggregate liquidation amount of Preferred Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Preferred Securities outstanding, and only after satisfaction of all amounts owed to the applicable Holders of the Preferred Securities, to each applicable Holder of Common Securities pro rata according to the aggregate liquidation amount of Common Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Common Securities outstanding.

A-8

9. RANKING.

The Preferred Securities rank pari passu and payment thereon shall be made Pro Rata with the Common Securities except that, where an Event of Default occurs and is continuing under the Indenture in respect of the Subordinated Debentures held by the Property Trustee, the rights of Holders of the Common Securities to payment in respect of Distributions and payments upon liquidation, redemption and otherwise are subordinated to the rights to payment of the Holders of the Preferred Securities.

10. ACCEPTANCE OF TRUST SECURITIES GUARANTEE AND INDENTURE.

Each Holder of Preferred Securities and Common Securities, by the acceptance thereof, agrees to the provisions of the Preferred Securities Guarantee and the Common Securities Guarantee, respectively, including the subordination provisions therein and to the provisions of the Indenture.

11. NO PREEMPTIVE RIGHTS.

The Holders of the Trust Securities shall have no preemptive rights to subscribe for any additional securities.

12. MISCELLANEOUS.

These terms constitute a part of the Declaration.

The Sponsor will provide a copy of the Declaration, the Preferred Securities Guarantee or and the Common Securities Guarantee (as may be appropriate), and the Indenture to a Holder without charge on written request to the Trust at its principal place of business.

(b) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Trust and upon such information, opinions, reports or statements presented to the Trust by any Person as to matters the Indemnified Person reasonably believes are within such other Person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Trust, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits, losses, or any other facts pertinent to the existence and amount of assets from which Distributions to Holders of Trust Securities might properly be paid.

(a) To the extent that, at law or in equity, an Indemnified Person has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to any other Covered Person, an Indemnified Person acting under this Declaration shall not be liable to the Trust or to any other Covered Person for its good faith reliance on the provisions of this Declaration. The provisions of this Declaration, to the extent that they restrict the duties and liabilities of an Indemnified Person otherwise existing at law or in equity (other than the duties imposed on the Property Trustee under the Trust Indenture Act, if any), are agreed by the parties hereto to replace such other duties and liabilities of such Indemnified Person.

(b) Unless otherwise expressly provided herein:

(i) whenever a conflict of interest exists or arises between an Indemnified Person and any Covered Person; or

(ii) whenever this Declaration or any other agreement contemplated herein or therein provides that an Indemnified Person shall act in a manner that is, or provides terms that are, fair and reasonable to the Trust or any Holder of Trust Securities, the Indemnified Person shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Indemnified Person, the resolution, action or term so made, taken or provided by this Indemnified Person shall not constitute a breach of this Declaration or any other agreement contemplated herein or of any duty or obligation of the Indemnified Person at law or in equity or otherwise.

(c) Whenever in this Declaration an Indemnified Person is permitted or required to make a decision:

(i) in its "discretion" or under a grant of similar authority, the Indemnified Person shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust or any other Person; or

(ii) in its "good faith" or under another express standard, the Indemnified Person shall act under such express standard and shall not be subject to any other or different standard imposed by this Declaration or by applicable law.

(b) To the fullest extent permitted by applicable law, expenses (including legal fees) incurred by an Indemnified Person in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Sponsor prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined that the Indemnified Person is not entitled to be indemnified as authorized in Section 10.4(a). The indemnification shall survive the termination of this Declaration or the earlier removal or resignation of any of the Trustees or the Property Trustee.

SECTION 10.5. OUTSIDE BUSINESSES

Any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Trust, and the Trust and the Holders of Trust Securities shall have no rights by virtue of this Declaration in and to such independent ventures or the income or profits derived therefrom and the pursuit of any such venture, even if competitive with the business of the Trust, shall not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware Trustee or the Property Trustee shall be obligated to present any particular investment or other opportunity to the Trust even if such opportunity is of a character that, if presented to the Trust, could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee shall have the right to take for its own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment or other opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee may engage or be interested in any financial or other transaction with the Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or act on any committee or body of holders of, securities or other obligations of the Sponsor or its Affiliates.

ACCOUNTING

SECTION 11.1. FISCAL YEAR

The fiscal year ("FISCAL YEAR") of the Trust shall be the calendar year, or such other year as is required by the Code.

SECTION 11.2. CERTAIN ACCOUNTING MATTERS

(a) At all times during the existence of the Trust, the Regular Trustees shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail, each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently applied. The Trust shall use the accrual method of accounting for United States federal income tax purposes. The books of account and the records of the Trust shall be examined by and reported upon as of the end of each Fiscal Year by a firm of independent certified public accountants selected by the Regular Trustees.

(b) The Regular Trustees shall cause to be prepared and delivered to each of the Holders of Trust Securities, within 90 days after the end of each Fiscal Year of the Trust, annual financial statements of the Trust, including a balance sheet of the Trust as of the end of such Fiscal Year, and the related statements of income or loss.

(c) The Regular Trustees shall cause to be duly prepared and delivered to each of the Holders of Trust Securities any United States federal income tax information statement required by the Code, containing such information with regard to the Trust Securities held by each Holder as is required by the Code and the Treasury Regulations, and any comparable statements required to be provided under the law of any other taxing jurisdiction. Notwithstanding any right under the Code or other law to deliver any such statement at a later date, the Regular Trustees shall endeavor to deliver all such statements within 30 days after the end of each Fiscal Year of the Trust.

(d) The Regular Trustees shall cause to be duly prepared and filed with the appropriate taxing authority an annual United States federal income tax return Form 1041 (or any successor form) or such other form required by United States federal income tax law, and any other tax returns or reports required to be filed by the Regular Trustees on behalf of the Trust with any state or local taxing authority.

SECTION 11.3. BANKING

The Trust shall maintain one or more bank accounts in the name and for the sole benefit of the Trust; provided, however, that all payments of funds in respect of the Subordinated Debentures held by the Property Trustee shall be made directly to the Property Trustee Account and no other funds of the Trust shall be deposited in the Property Trustee Account.

The Regular Trustees shall file required forms with applicable jurisdictions and, unless an exemption from withholding is properly established by a Holder, shall remit amounts withheld with respect to the Holder to applicable jurisdictions. To the extent that the Trust is required to withhold and pay over any amounts to any authority with respect to distributions or allocations to any Holder, the amount withheld shall be deemed to be a distribution in the amount of the withholding to the Holder. In the event of any claimed over withholding, Holders shall be limited to an action against the applicable jurisdiction. If the amount required to be withheld was not withheld from actual Distributions made to any Holder, the Trust may reduce subsequent Distributions to such Holder by the amount of such withholding.

The Regular Trustees shall call a meeting of the Holders of such class if directed to do so by the Holders of at least 10% in liquidation amount of such class of Trust Securities. Such direction shall be given by delivering to the Regular Trustees one or more calls in a writing stating that the signing Holders of Trust Securities wish to call a meeting and indicating the general or specific purpose for which the meeting is to be called.

Any action that may be taken at a meeting of the Holders of Trust Securities may be taken without a meeting if a consent in writing setting forth the action so taken is signed by the Holders of Trust Securities owning not less than the minimum amount of Trust Securities in liquidation amount that would be necessary to authorize or take such action at a meeting at which all Holders of Trust Securities having a right to vote thereon were present and voting. Prompt notice of the taking of action without a meeting shall be given to the Holders of Trust Securities entitled to vote who have not consented in writing. The Regular Trustees may specify that any written ballot submitted to a Holder for the purpose of taking any action without a meeting shall be returned to the Trust within the time specified by the Regular Trustees;

Every proxy shall be revocable at the pleasure of the Holder of Trust Securities executing it. Except as otherwise provided herein, all matters relating to the giving, voting or validity of proxies shall be governed by the General Corporation Law of the State of Delaware relating to proxies, and judicial interpretations thereunder, as if the Trust were a Delaware corporation and the Holders of the Trust Securities were stockholders of a Delaware corporation;

(iii) each meeting of the Holders of the Trust Securities shall be conducted by the Regular Trustees or by such other Person that the Regular Trustees may designate; and

-35-

(iv) unless the Business Trust Act, this Declaration, the terms of the Trust Securities, or the Trust Indenture Act otherwise provides, the Regular Trustees, in their sole discretion, shall establish all other provisions relating to meetings of Holders of Trust Securities, including notice of the time, place or purpose of any meeting at which any matter is to be voted on by any Holders of Trust Securities, waiver of any such notice, action by consent without a meeting, the establishment of a record date, quorum requirements, voting in person or by proxy or any other matter with respect to the exercise of any such right to vote.

Up to 12,920,000 Preferred Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Three Hundred Twenty Three Million Dollars ($323,000,000) and a liquidation amount with respect to the assets of the Trust of $25 per Preferred Security, are hereby designated for the purposes of identification only as "11% Trust Issued Preferred Securities" (the "PREFERRED SECURITIES"). The Certificates evidencing the Preferred Securities shall be substantially in the form attached hereto as Annex I, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.

(b) COMMON SECURITIES. Up to 399,588 Common Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Nine Million Nine Hundred Eighty Nine Thousand Seven Hundred Dollars ($9,989,700) and a liquidation amount with respect to the assets of the Trust of $25 per Common Security, are hereby designated for the purposes of identification only as "11% Trust Issued Common Securities" (the "COMMON SECURITIES"). The Certificates evidencing the Common Securities shall be substantially in the form attached hereto as Annex II, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.

2. DISTRIBUTIONS.

(a) Distributions payable on each Trust Security will be fixed at a rate per annum of 11% (the "COUPON RATE") of the stated liquidation amount of $25 per Trust Security, such rate being the rate of interest payable on the Subordinated Debentures to be held by the Property Trustee. Distributions in arrears for more than one semi-annual period will bear interest thereon compounded semi-annually at the Coupon Rate (to the extent permitted by applicable law). The term "DISTRIBUTIONS" as used herein includes such cash distributions and any such interest payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Subordinated Debentures held by the Property Trustee. The amount of Distributions payable for any period will be computed for any full semi-annual Distribution period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a


full semi-annual Distribution period for which Distributions are computed, Distributions will be computed on the basis of the actual number of days elapsed per 30-day month.

(b) Distributions on each series of Trust Securities will be cumulative, will accumulate from the date of original issuance of the Trust Securities of such series (the "SERIES ISSUE DATE"), and will be payable semi-annually in arrears, on June 15 and December 15 of each year, commencing on the first such date following the Series Issue Date, except as otherwise described below. The Sponsor has the right under the Indenture to defer payments of interest by extending the interest payment period from time to time and for varying lengths of time on the Subordinated Debentures for a period not exceeding 10 consecutive semi-annual periods (each, an "EXTENSION PERIOD") and during such Extension Period, Distributions will also be deferred. Despite such deferral, semi-annual Distributions will continue to accumulate with interest thereon (to the extent permitted by applicable law) at an annual rate of thirteen percent (13%) per annum compounded semi-annually during any such Extension Period. Prior to the termination of any such Extension Period, the Sponsor may further extend such Extension Period; provided that such Extension Period together with all such previous and further extensions thereof may not exceed 10 consecutive semi-annual periods. Payments of accumulated Distributions will be payable to Holders as they appear on the books and records of the Trust on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Sponsor may commence a new Extension Period, subject to the above requirements.

(c) Distributions on the Trust Securities will be payable to the Holders thereof as they appear on the books and records of the Trust on the relevant record dates. Distributions payable on any Trust Securities that are not punctually paid on any Distribution payment date, as a result of the Sponsor having failed to make a payment under the Subordinated Debentures, will cease to be payable to the Person in whose name such Trust Securities are registered on the relevant record date, and such Distribution will instead be payable to the Person in whose name such Trust Securities are registered on the special record date or other specified date determined in accordance with the Indenture. If any date on which Distributions are payable on the Trust Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date.

(d) In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed Pro Rata (as defined herein) among the Holders of the Trust Securities.

3. LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

In the event of any voluntary or involuntary dissolution of the Trust, the Holders of the Trust Securities on the date of the dissolution will be entitled to receive out of the assets of the Trust available for distribution to Holders of Trust Securities after satisfaction of liabilities to creditors of the Trust, if any (including, without limitation, by paying or making reasonable provisions to pay all claims and obligations of the Trust in accordance with Section 3808(e) of

A-2

the Business Trust Act), an amount equal to the aggregate of the stated liquidation amount of $25 per Trust Security plus accumulated and unpaid Distributions thereon (including interest thereon) to the date of payment (such amount being the "LIQUIDATION DISTRIBUTION"), unless, in connection with such dissolution, after satisfaction of liabilities to creditors of the Trust (including, without limitation, by paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act) Subordinated Debentures in an aggregate principal amount equal to the aggregate stated liquidation amount of such Trust Securities and of like tenor shall be distributed on a Pro Rata basis to the Holders of the Trust Securities in exchange for such Trust Securities.

If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Trust Securities shall be paid on a Pro Rata basis. The holders of the Common Securities will be entitled to receive distributions upon any such dissolution Pro Rata with the holders of the Preferred Securities, except that if an Event of Default has occurred and is continuing, the Preferred Securities shall have a preference over the Common Securities with regard to such distributions.

On and from the date fixed by the Regular Trustees for any distribution of Subordinated Debentures: (i) the Trust Securities will no longer be deemed to be outstanding, (ii) the Depositary, as the Holder of the Preferred Securities, will receive a registered global certificate representing the Subordinated Debentures to be delivered upon such distribution, and (iii) any certificates representing Trust Securities not held by the Depositary or its nominee (or any successor depositary or its nominee), will be deemed to represent beneficial interests in the Subordinated Debentures having an aggregate principal amount equal to the aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accumulated and unpaid Distributions on, such Trust Securities until such certificates are presented to the Sponsor or its agent for transfer or reissue.

4. REDEMPTION; REDEMPTION/DISTRIBUTION PROCEDURES.

(a) Upon the repayment of a series of Subordinated Debentures (a "DEBENTURE SERIES"), whether at the Maturity Date or upon redemption thereof, in whole or in part, the proceeds from such repayment or redemption shall be simultaneously applied to redeem the series of Trust Securities used to purchase such Debenture Series, having an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Debentures so repaid or redeemed at a redemption price of $25 per Trust Security plus an amount equal to accumulated and unpaid Distributions thereon at the date of the redemption, payable in cash (the "REDEMPTION PRICE"). Applicable Holders will be given not less than 30 nor more than 60 days notice of such redemption.

(b) If fewer than all the outstanding Trust Securities in a series are to be so redeemed, the applicable Preferred Securities and the applicable Common Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed will be as described in Section 4(d)(ii) below.

A-3

(c) The Trust may not redeem fewer than all the outstanding Trust Securities unless all accumulated and unpaid Distributions have been paid on all Trust Securities for all semi-annual Distribution periods terminating on or before the date of redemption.

(d) (i) Notice of any redemption of a series of Trust Securities, or notice of distribution of Subordinated Debentures in exchange for the Trust Securities (a "REDEMPTION/DISTRIBUTION NOTICE"), will be given by the Regular Trustees on behalf of the Trust by mail to each Holder of Trust Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days before the date fixed for redemption or exchange thereof which, in the case of a redemption, will be the date fixed for redemption of the Subordinated Debentures. For purposes of the calculation of the date of redemption or exchange and the dates on which notices are given pursuant to this Section 4(d)(i), a Redemption/Distribution Notice shall be deemed to be given on the day such notice is first mailed by first-class mail, postage prepaid, to Holders of Trust Securities. Each Redemption/Distribution Notice shall be addressed to the Holders of Trust Securities at the address of each such Holder appearing in the books and records of the Trust. No defect in the Redemption/Distribution Notice or in the mailing of either thereof with respect to any Holder shall affect the validity of the redemption or exchange proceedings with respect to any other Holder.

(ii) In the event that fewer than all the outstanding Trust Securities are to be redeemed, the Trust Securities to be redeemed shall be redeemed Pro Rata.

(iii) If Trust Securities are to be redeemed and the Regular Trustees on behalf of the Trust give a Redemption/Distribution Notice, which notice may only be issued if the Subordinated Debentures are redeemed as set out in this Section 4 (which notice will be irrevocable), then with respect to Preferred Securities and Common Securities, provided that the Sponsor has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Debentures, then the Property Trustee will pay the relevant Redemption Price to the Holders of such Trust Securities by check mailed to the address of the relevant Holder appearing on the books and records of the Trust on the redemption date upon surrender of their Certificates evidencing such Preferred Securities and such Common Securities. If a Redemption/Distribution Notice shall have been given and funds deposited as required, then immediately prior to the close of business on the date of such deposit, or on the redemption date, as applicable, Distributions will cease to accumulate on the Trust Securities so called for redemption and all rights of Holders of such Trust Securities so called for redemption will cease, except the right of the Holders of such Trust Securities to receive the Redemption Price, but without interest on such Redemption Price. Neither the Regular Trustees nor the Trust shall be required to register or cause to be registered the transfer of any Trust Securities that have been so called for redemption. If any date fixed for redemption of Trust Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Redemption Price in respect of any Trust Securities is improperly withheld or refused and not paid either by the Property Trustee or by the Sponsor as guarantor pursuant to the Preferred Securities Guarantee or the Common Securities Guarantee, as the case may be, Distributions on such Trust Securities

A-4

will continue to accumulate from the original redemption date to the actual date of payment, in which case the actual payment date will be considered the date fixed for redemption for purpose of calculating the Redemption Price.

(iv) Redemption/Distribution Notices shall be sent by the Regular Trustees on behalf of the Trust to the Holder.

(v) Subject to the foregoing and applicable law (including, without limitation, United States federal securities laws), provided the acquirer is not the Holder of the Common Securities or the obligor under the Indenture, the Sponsor or any of its subsidiaries may at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement.

5. VOTING RIGHTS - PREFERRED SECURITIES.

(a) Except as provided under Sections 5(b) and 6 and as otherwise required by law, the Preferred Securities Guarantee and the Declaration, the Holders of the Preferred Securities will have no voting rights.

(b) Subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Preferred Securities, voting as a class may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee with respect to the Subordinated Debentures, (ii) waiving any past default and its consequences that is waivable under Section 4.13 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable, provided, however, that, where a consent under the Indenture would require the consent or act of all of the holders of Subordinated Debentures affected thereby, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Preferred Securities. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration or the Subordinated Debentures, any Holder of Preferred Securities may institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration or the Subordinated Debentures without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Preferred Securities may directly

A-5

institute a proceeding for enforcement of payment to such Holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such Holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Preferred Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Preferred Securities in connection with such direct action. Any approval or direction of Holders of Preferred Securities may be given at a separate meeting of Holders of Preferred Securities convened for such purpose, at a meeting of all the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Preferred Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which the written consent is sought and (iii) instructions for the delivery of proxies or consents.

No vote or consent of the Holders of the Preferred Securities will be required for the Trust to redeem and cancel Preferred Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

Notwithstanding that Holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall not be entitled to vote or consent and shall, for purposes of such vote or consent, be treated as if they were not outstanding.

6. VOTING RIGHTS - COMMON SECURITIES.

(a) Except as provided under Sections 6(b) and 6(c), and as otherwise required by law and the Declaration, the Holders of the Common Securities will have no voting rights.

(b) The Holders of the Common Securities are entitled, in accordance with Article V of the Declaration, to vote to appoint, remove or replace any Trustee or to increase or decrease the number of Trustees.

(c) Subject to Section 2.6 of the Declaration, only after an Event of Default with respect to the Preferred Securities has been cured, waived or otherwise eliminated and subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Common Securities, voting separately as a class, may direct the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred on the Property Trustee with respect to the Subordinated Debentures, (ii) waiving any past default and its consequences that is waivable under Section 4.13 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable, provided, however, that, where a consent or action under the Indenture would require the consent

A-6

or act of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Common Securities. Pursuant to this Section 6(c), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Common Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Common Securities under this paragraph unless the Property Trustee has obtained, at the expense of the Holders of the Common Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration and the Subordinated Debentures, any Holder of Common Securities may after written request to the Property Trustee to enforce such rights, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration and the Subordinated Debentures, without first instituting a legal proceeding against the Property Trustee or any other person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Common Securities may directly institute a proceeding for enforcement of payment to such holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Common Securities of such holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Common Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Common Securities in connection with such direct action.

Any approval or direction of Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purpose, at a meeting of all of the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Common Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. No vote or consent of the Holders of the Common Securities will be required for the Trust to redeem and cancel Common Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

7. AMENDMENTS TO DECLARATION AND INDENTURE.

(a) If any proposed amendment to the Declaration provides for, or the Regular Trustees otherwise propose to effect (i) any action that would adversely affect the powers, preferences or special rights of the Trust Securities, whether by way of amendment to the Declaration or otherwise, or (ii) the involuntary or voluntary liquidation, dissolution, winding-up

A-7

or termination of the Trust, other than as described in Section 8.1 of the Declaration, then the Holders of outstanding Trust Securities as a class, will be entitled to vote on such amendment or proposal (but not on any other amendment or proposal) and such amendment or proposal shall not be effective except with the approval of the Holders of at least 66-2/3% in liquidation amount of the Trust Securities, voting together as a single class; provided that a reduction of the aggregate liquidation amount or the Distribution rate, a change in the payment dates or maturities of the Preferred Securities or a reduction in the percentage in liquidation amount of outstanding Preferred Securities, the consent of the Holders of which is required for an amendment to the Declaration shall not be permitted without the consent of each Holder of the Preferred Securities. In the event any amendment or proposal referred to in clause (i) above would adversely affect only the Preferred Securities or only the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of 66-2/3% in liquidation amount of such class of Trust Securities.

(b) In the event the consent of the Property Trustee, as the holder of the Subordinated Debentures, the Preferred Securities Guarantee and the Common Securities Guarantee is required under the Indenture with respect to any amendment, modification, waiver or termination of the Indenture, the Subordinated Debentures, the Preferred Securities Guarantee or the Common Securities Guarantee, the Property Trustee shall request the direction of the Holders of the Trust Securities with respect to such amendment, modification, waiver or termination and shall vote with respect to such amendment, modification, waiver or termination as directed by a Majority in liquidation amount of the Trust Securities voting together as a single class; provided, however, that where a consent under the Indenture would require the consent of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent at the direction of all of the Holders of the Trust Securities; provided, further, that the Property Trustee shall not take any action in accordance with the directions of the Holders of the Trust Securities under this Section 6(b) unless the Property Trustee has obtained, at the expense of the Holders of the Trust Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action.

8. PRO RATA.

A reference to any payment, distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder of applicable Trust Securities according to the aggregate liquidation amount of such Trust Securities held by the relevant Holder in relation to the aggregate liquidation amount of all applicable Trust Securities outstanding unless, in relation to a payment, an Event of Default under the Indenture has occurred and is continuing, in which case any funds available to make such payment shall be paid first to each Holder of the applicable Preferred Securities pro rata according to the aggregate liquidation amount of Preferred Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Preferred Securities outstanding, and only after satisfaction of all amounts owed to the applicable Holders of the Preferred Securities, to each applicable Holder of Common Securities pro rata according to the aggregate liquidation amount of Common Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Common Securities outstanding.

A-8

9. RANKING.

The Preferred Securities rank pari passu and payment thereon shall be made Pro Rata with the Common Securities except that, where an Event of Default occurs and is continuing under the Indenture in respect of the Subordinated Debentures held by the Property Trustee, the rights of Holders of the Common Securities to payment in respect of Distributions and payments upon liquidation, redemption and otherwise are subordinated to the rights to payment of the Holders of the Preferred Securities.

10. ACCEPTANCE OF TRUST SECURITIES GUARANTEE AND INDENTURE.

Each Holder of Preferred Securities and Common Securities, by the acceptance thereof, agrees to the provisions of the Preferred Securities Guarantee and the Common Securities Guarantee, respectively, including the subordination provisions therein and to the provisions of the Indenture.

11. NO PREEMPTIVE RIGHTS.

The Holders of the Trust Securities shall have no preemptive rights to subscribe for any additional securities.

12. MISCELLANEOUS.

These terms constitute a part of the Declaration.

The Sponsor will provide a copy of the Declaration, the Preferred Securities Guarantee or and the Common Securities Guarantee (as may be appropriate), and the Indenture to a Holder without charge on written request to the Trust at its principal place of business.

RECITALS

WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the "DECLARATION"), dated as of March 12, 2002, among the trustees of the Trust named therein, the Guarantor as sponsor and the holders from time to time of undivided beneficial interests in the assets of the Trust, the Trust will be issuing from time to time up to $323,000,000 aggregate stated liquidation amount of Preferred Securities designated the 11% Trust Issued Preferred Securities (the "PREFERRED SECURITIES"); and

Such signatures may be the manual or facsimile signatures of the present or any future Regular Trustee. Typographical and other minor errors or defects in any such reproduction of any such signature shall not affect the validity of any Certificate. In case any Regular Trustee of the Trust who shall have signed any of the Trust Securities shall cease to be such Regular Trustee before the Certificates so signed shall be delivered by the Trust, such Certificates nevertheless may be delivered as though the person who signed such Certificates had not ceased to be such Regular Trustee; and any Certificate may be signed on behalf of the Trust by such persons who, at the actual date of execution of such Trust Security, shall be the Regular Trustees of the Trust, although at the date of the execution and delivery of this Declaration any such person was not such a Regular Trustee. Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Regular Trustees, as evidenced by their execution thereof, and may have such letters, numbers or other marks or identification or designation and such legends or endorsements as the Regular Trustees may deem appropriate, or as may be required to comply with any law or with any rule or regulation usage.

(c) The consideration shall be received by the Property Trustee for the issuance of the Trust Securities, which consideration shall constitute a contribution to the capital of the Trust and shall not constitute a loan to the Trust.

(d) The Holders shall not have any right or title in the assets of the Trust other than an undivided beneficial interest in such assets conferred by their Trust

-31-

Securities, and they shall have no right to call for any partition or division of any property, profits or rights of the Trust except as otherwise provided herein. The Trust Securities shall be personal property giving only the rights specifically set forth therein and in this Declaration. The Trust Securities, when issued and delivered against payment of purchase price therefor, shall be deemed to be validly issued, fully paid and non-assessable by the Trust.

(e) Every Person, by virtue of having become a Holder in accordance with the terms of this Declaration, shall be deemed to have expressly assented and agreed to the terms of, and shall be bound by, this Declaration.

(b) Subject to this Article IX, Preferred Securities shall be transferable only to Permitted Holders.

(c) Subject to this Article IX, the Sponsor and any Related Party may only transfer Common Securities to the Sponsor or a Related Party of the Sponsor; provided that, any such transfer is subject to the conditions precedent that the transferor obtain the written opinion of nationally recognized independent counsel experienced in such matters that such transfer would not cause more than an insubstantial risk that:

SECTION 9.2 TRANSFER OF CERTIFICATES.

Each Certificate surrendered for registration of transfer shall be canceled by the Regular Trustees. A transferee of a Certificate shall be entitled to the rights and subject to the obligations of a Holder hereunder upon the receipt by such transferee of a Certificate. By acceptance of a Certificate, each transferee shall be deemed to have agreed to be bound by this Declaration and the documents incorporated by reference herein.

The Trustees may treat the Person in whose name any Certificate shall be registered on the books and records of the Trust as the sole holder of such Certificate and of the Trust Securities represented by such Certificate for purposes of receiving Distributions and for all other purposes whatsoever and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Certificate or in the Trust Securities represented by such Certificate on the part of any Person, whether or not the Trust shall have actual or other notice thereof.

SECTION 9.4 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

If (a) any mutilated Certificates should be surrendered to the Regular Trustees, or if the Regular Trustees shall have received evidence to their satisfaction of the destruction, loss or theft of any Certificate; and (b) there shall be delivered to the Regular Trustees such security or indemnity as may be required by them to keep each of them harmless, then in the absence of notice that such Certificate shall have been acquired by a bona fide purchaser, any two Regular Trustees on behalf of the Trust shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like denomination. In connection with the issuance of any new Certificate under this Section 9.4, the Regular Trustees may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Certificate issued pursuant to this Section shall constitute conclusive evidence of an ownership interest in the relevant Trust Certificates, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

ACCOUNTING

SECTION 11.1 FISCAL YEAR.

The fiscal year ("Fiscal Year") of the Trust shall be the calendar year, or such other year as is required by the Code.

SECTION 11.2 CERTAIN ACCOUNTING MATTERS.

(a) At all times during the existence of the Trust, the Regular Trustees shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail, each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently applied. The Trust shall use the accrual method of accounting for United States federal income tax purposes. The books of account and the records of the Trust shall be examined by and reported upon as of the end of each Fiscal Year by a firm of independent certified public accountants selected by the Regular Trustees.

(b) The Regular Trustees shall cause to be prepared and delivered to each of the Holders of Trust Securities, within 90 days after the end of each Fiscal Year of the Trust, annual financial statements of the Trust, including a balance sheet of the Trust as of the end of such Fiscal Year, and the related statements of income or loss.

(c) The Regular Trustees shall cause to be duly prepared and delivered to each of the Holders of Trust Securities any United States federal income tax information statement required by the Code, containing such information with regard to the Trust Securities held by each Holder as is required by the Code and the Treasury Regulations, and any comparable statements required to be provided under the law of any other taxing jurisdiction. Notwithstanding any right under the Code or other law to deliver any such statement at a later date, the Regular Trustees shall

-38-

endeavor to deliver all such statements within 30 days after the end of each Fiscal Year of the Trust.

(d) The Regular Trustees shall cause to be duly prepared and filed with the appropriate taxing authority an annual United States federal income tax return Form 1041 (or any successor form) or such other form required by United States federal income tax law, and any other tax returns or reports required to be filed by the Regular Trustees on behalf of the Trust with any state or local taxing authority.

SECTION 11.3 BANKING.

The Trust shall maintain one or more bank accounts in the name and for the sole benefit of the Trust; provided, however, that all payments of funds in respect of the Subordinated Debentures held by the Property Trustee shall be made directly to the Property Trustee Account and no other funds of the Trust shall be deposited in the Property Trustee Account. The sole signatories for such accounts shall be designated by the Regular Trustees; provided, however, that the Property Trustee shall designate the sole signatories for the Property Trustee Account.

SECTION 11.4 WITHHOLDING.

The Trust and the Regular Trustees shall comply with all withholding requirements under United States federal, state and local law. The Trust shall request, and the Holders shall provide to the Trust, such forms or certificates as are necessary to establish an exemption from withholding with respect to each Holder, and any representations and forms as shall reasonably be requested by the Trust to assist it in determining the extent of, and in fulfilling, its withholding obligations. The Regular Trustees shall file required forms with applicable jurisdictions and, unless an exemption from withholding is properly established by a Holder, shall remit amounts withheld with respect to the Holder to applicable jurisdictions. To the extent that the Trust is required to withhold and pay over any amounts to any authority with respect to distributions or allocations to any Holder, the amount withheld shall be deemed to be a distribution in the amount of the withholding to the Holder. In the event of any claimed over withholding, Holders shall be limited to an action against the applicable jurisdiction. If the amount required to be withheld was not withheld from actual Distributions made to any Holder, the Trust may reduce subsequent Distributions to such Holder by the amount of such withholding.

EXHIBIT A

TERMS OF
11% TRUST ISSUED PREFERRED SECURITIES
11% TRUST ISSUED COMMON SECURITIES

Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust, dated as of March __, 2000 (as amended from time to time, the "DECLARATION"), the designation, rights, privileges, restrictions, preferences and other terms and provisions of the Preferred Securities and the Common Securities are set out below (each capitalized term used but not defined herein has the meaning set forth in the Declaration). The Trust may issue one or more series of Preferred Securities and one or more series of Common Securities, provided, however, that the original principal amount of each series (other than the final series) of Preferred Securities must be at least $50,000,000.

1. DESIGNATION AND NUMBER.

(a) PREFERRED SECURITIES. Up to 32,000,000 Preferred Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Eight Hundred Million Dollars ($800,000,000) and a liquidation amount with respect to the assets of the Trust of $25 per Preferred Security, are hereby designated for the purposes of identification only as "11% Trust Issued Preferred Securities" (the "PREFERRED Securities"). The Certificates evidencing the Preferred Securities shall be substantially in the form attached hereto as Annex I, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.

(b) COMMON SECURITIES. Up to 989,691 Common Securities of the Trust, in one or more series, with an aggregate liquidation amount with respect to the assets of the Trust of up to Twenty-Four Million Seven Hundred Forty Two Thousand Two Hundred Seventy Five Dollars ($24,742,275) and a liquidation amount with respect to the assets of the Trust of $25 per Common Security, are hereby designated for the purposes of identification only as "11% Trust Issued Common Securities" (the "Common Securities"). The Certificates evidencing the Common Securities shall be substantially in the form attached hereto as Annex II, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice.


2. DISTRIBUTIONS.

(a) Distributions payable on each Trust Security will be fixed at a rate per annum of 11% (the "COUPON RATE") of the stated liquidation amount of $25 per Trust Security, such rate being the rate of interest payable on the Subordinated Debentures to be held by the Property Trustee. Distributions in arrears for more than one semi-annual period will bear interest thereon compounded semi-annually at the Coupon Rate (to the extent permitted by applicable law). The term "Distributions" as used herein includes such cash distributions and any such interest payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Subordinated Debentures held by the Property Trustee. The amount of Distributions payable for any period will be computed for any full semi-annual Distribution period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full semi-annual Distribution period for which Distributions are computed, Distributions will be computed on the basis of the actual number of days elapsed per 30-day month.

(b) Distributions on each series of Trust Securities will be cumulative, will accumulate from the date of original issuance of the Trust Securities of such series (the "Series Issue Date"), and will be payable semi-annually in arrears, on June 15 and December 15 of each year, commencing on the first such date following the Series Issue Date, except as otherwise described below. The Sponsor has the right under the Indenture to defer payments of interest by extending the interest payment period from time to time and for varying lengths of time on the Subordinated Debentures for a period not exceeding 10 consecutive semi-annual periods (each, an "Extension Period") and during such Extension Period, Distributions will also be deferred. Despite such deferral, semi-annual Distributions will continue to accumulate with interest thereon (to the extent permitted by applicable law) at an annual rate of thirteen percent (13%) per annum compounded semi-annually during any such Extension Period. Prior to the termination of any such Extension Period, the Sponsor may further extend such Extension Period; provided that such Extension Period together with all such previous and further extensions thereof may not exceed 10 consecutive semi-annual periods. Payments of accumulated Distributions will be payable to Holders as they appear on the books and records of the Trust on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Sponsor may commence a new Extension Period, subject to the above requirements.

(c) Distributions on the Trust Securities will be payable to the Holders thereof as they appear on the books and records of the Trust on the relevant record dates. Distributions payable on any Trust Securities that are not punctually paid on any Distribution payment date, as a result of the Sponsor having failed to make a payment under the Subordinated Debentures, will cease to be payable to the Person

-2-

in whose name such Trust Securities are registered on the relevant record date, and such Distribution will instead be payable to the Person in whose name such Trust Securities are registered on the special record date or other specified date determined in accordance with the Indenture. If any date on which Distributions are payable on the Trust Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date.

(d) In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed Pro Rata (as defined herein) among the Holders of the Trust Securities.

3. LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

In the event of any voluntary or involuntary dissolution of the Trust, the Holders of the Trust Securities on the date of the dissolution will be entitled to receive out of the assets of the Trust available for distribution to Holders of Trust Securities after satisfaction of liabilities to creditors of the Trust, if any (including, without limitation, by paying or making reasonable provisions to pay all claims and obligations of the Trust in accordance with
Section 3808(e) of the Business Trust Act), an amount equal to the aggregate of the stated liquidation amount of $25 per Trust Security plus accumulated and unpaid Distributions thereon (including interest thereon) to the date of payment (such amount being the "LIQUIDATION DISTRIBUTION"), unless, in connection with such dissolution, after satisfaction of liabilities to creditors of the Trust (including, without limitation, by paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act) Subordinated Debentures in an aggregate principal amount equal to the aggregate stated liquidation amount of such Trust Securities and of like tenor shall be distributed on a Pro Rata basis to the Holders of the Trust Securities in exchange for such Trust Securities.

If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Trust Securities shall be paid on a Pro Rata basis. The holders of the Common Securities will be entitled to receive distributions upon any such dissolution Pro Rata with the holders of the Preferred Securities, except that if an Event of Default has occurred and is continuing, the Preferred Securities shall have a preference over the Common Securities with regard to such distributions.

-3-

On and from the date fixed by the Regular Trustees for any distribution of Subordinated Debentures: (i) the Trust Securities will no longer be deemed to be outstanding, (ii) the Depositary, as the Holder of the Preferred Securities, will receive a registered global certificate representing the Subordinated Debentures to be delivered upon such distribution, and (iii) any certificates representing Trust Securities not held by the Depositary or its nominee (or any successor depositary or its nominee), will be deemed to represent beneficial interests in the Subordinated Debentures having an aggregate principal amount equal to the aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accumulated and unpaid Distributions on, such Trust Securities until such certificates are presented to the Sponsor or its agent for transfer or reissue.

4. REDEMPTION; REDEMPTION/DISTRIBUTION PROCEDURES.

(a) Upon the repayment of a series of Subordinated Debentures (a "Debenture Series"), whether at the Maturity Date or upon redemption thereof, in whole or in part, the proceeds from such repayment or redemption shall be simultaneously applied to redeem the series of Trust Securities used to purchase such Debenture Series, having an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Debentures so repaid or redeemed at a redemption price of $25 per Trust Security plus an amount equal to accumulated and unpaid Distributions thereon at the date of the redemption, payable in cash (the "Redemption Price"). Applicable Holders will be given not less than 30 nor more than 60 days notice of such redemption.

(b) If fewer than all the outstanding Trust Securities in a series are to be so redeemed, the applicable Preferred Securities and the applicable Common Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed will be as described in Section 4(d)(ii) below.

(c) The Trust may not redeem fewer than all the outstanding Trust Securities unless all accumulated and unpaid Distributions have been paid on all Trust Securities for all semi-annual Distribution periods terminating on or before the date of redemption.

(d) (i) Notice of any redemption of a series of Trust Securities, or notice of distribution of Subordinated Debentures in exchange for the Trust Securities (a "REDEMPTION/DISTRIBUTION NOTICE"), will be given by the Regular Trustees on behalf of the Trust by mail to each Holder of Trust Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days before the date fixed for redemption or exchange thereof which, in the case of a redemption, will be the date fixed for redemption of the Subordinated Debentures. For purposes of the calculation of the date of

-4-

redemption or exchange and the dates on which notices are given pursuant to this Section 4(d)(i), a Redemption/Distribution Notice shall be deemed to be given on the day such notice is first mailed by first-class mail, postage prepaid, to Holders of Trust Securities. Each Redemption/Distribution Notice shall be addressed to the Holders of Trust Securities at the address of each such Holder appearing in the books and records of the Trust. No defect in the Redemption/Distribution Notice or in the mailing of either thereof with respect to any Holder shall affect the validity of the redemption or exchange proceedings with respect to any other Holder.

(ii) In the event that fewer than all the outstanding Trust Securities are to be redeemed, the Trust Securities to be redeemed shall be redeemed Pro Rata.

(iii) If Trust Securities are to be redeemed and the Regular Trustees on behalf of the Trust give a Redemption/Distribution Notice, which notice may only be issued if the Subordinated Debentures are redeemed as set out in this Section 4 (which notice will be irrevocable), then with respect to Preferred Securities and Common Securities, provided that the Sponsor has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Debentures, then the Property Trustee will pay the relevant Redemption Price to the Holders of such Trust Securities by check mailed to the address of the relevant Holder appearing on the books and records of the Trust on the redemption date upon surrender of their Certificates evidencing such Preferred Securities and such Common Securities. If a Redemption/Distribution Notice shall have been given and funds deposited as required, then immediately prior to the close of business on the date of such deposit, or on the redemption date, as applicable, Distributions will cease to accumulate on the Trust Securities so called for redemption and all rights of Holders of such Trust Securities so called for redemption will cease, except the right of the Holders of such Trust Securities to receive the Redemption Price, but without interest on such Redemption Price. Neither the Regular Trustees nor the Trust shall be required to register or cause to be registered the transfer of any Trust Securities that have been so called for redemption. If any date fixed for redemption of Trust Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If

-5-

payment of the Redemption Price in respect of any Trust Securities is improperly withheld or refused and not paid either by the Property Trustee or by the Sponsor as guarantor pursuant to the Preferred Securities Guarantee or the Common Securities Guarantee, as the case may be, Distributions on such Trust Securities will continue to accumulate from the original redemption date to the actual date of payment, in which case the actual payment date will be considered the date fixed for redemption for purpose of calculating the Redemption Price.

(iv) Redemption/Distribution Notices shall be sent by the Regular Trustees on behalf of the Trust to the Holder.

(v) Subject to the foregoing and applicable law (including, without limitation, United States federal securities laws), provided the acquirer is not the Holder of the Common Securities or the obligor under the Indenture, the Sponsor or any of its subsidiaries may at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement.

5. VOTING RIGHTS - PREFERRED SECURITIES.

(a) Except as provided under Sections 5(b) and 6 and as otherwise required by law, the Preferred Securities Guarantee and the Declaration, the Holders of the Preferred Securities will have no voting rights.

(b) Subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Preferred Securities, voting as a class may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee with respect to the Subordinated Debentures, (ii) waiving any past default and its consequences that is waivable under Section 413 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable, provided, however, that, where a consent under the Indenture would require the consent or act of all of the holders of Subordinated Debentures affected thereby, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Preferred Securities. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the

-6-

Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration or the Subordinated Debentures, any Holder of Preferred Securities may institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration or the Subordinated Debentures without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Preferred Securities may directly institute a proceeding for enforcement of payment to such holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Preferred Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Preferred Securities in connection with such direct action. Any approval or direction of Holders of Preferred Securities may be given at a separate meeting of Holders of Preferred Securities convened for such purpose, at a meeting of all the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Preferred Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which the written consent is sought and (iii) instructions for the delivery of proxies or consents.

No vote or consent of the Holders of the Preferred Securities will be required for the Trust to redeem and cancel Preferred Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

Notwithstanding that Holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall not be entitled to vote or consent and shall, for purposes of such vote or consent, be treated as if they were not outstanding.

6. VOTING RIGHTS - COMMON SECURITIES.

(a) Except as provided under Sections 6(b) and 6(c), and as otherwise required by law and the Declaration, the Holders of the Common Securities will have no voting rights.

(b) The Holders of the Common Securities are entitled, in accordance with Article V of the Declaration, to vote to appoint, remove or replace any Trustee or to increase or decrease the number of Trustees.

(c) Subject to Section 2.6 of the Declaration, only after an Event of Default with respect to the Preferred Securities has been cured, waived or otherwise eliminated and subject to the requirements set forth in this paragraph, the Holders of a Majority in liquidation amount of the Common Securities, voting separately as a class, may direct the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or the exercise of any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred on the Property Trustee with respect to the Subordinated Debentures, (ii) waiving any past default and its consequences that is waivable under Section 413 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Debentures shall be due and payable, provided, however, that, where a consent or action under the Indenture would require the consent or act of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent or take such action at the direction of all of the Holders of the Common Securities. Pursuant to this Section 6(c), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Common Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Indenture Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Common Securities under this paragraph unless the Property Trustee has obtained, at the expense of the Holders of the Common Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not fail to be classified as a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration and the Subordinated Debentures, any Holder of Common Securities may after written request to the Property Trustee to enforce such rights, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration and the Subordinated Debentures, without first instituting a legal proceeding against the Property Trustee or any other person. Notwithstanding the foregoing, if an Event of Default has occurred and is

-8-

continuing and such event is attributable to the failure of the Sponsor to pay interest or principal on the Subordinated Debentures on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Common Securities may directly institute a proceeding for enforcement of payment to such holder of the principal of or interest on the Subordinated Debentures having a principal amount equal to the aggregate liquidation amount of the Common Securities of such holder on or after the respective due dates specified in the Subordinated Debentures. In connection with such direct action, the Sponsor will be subrogated to the rights of such Holder of Common Securities under the Declaration to the extent of any payment made by the Sponsor to such Holder of Common Securities in connection with such direct action.

Any approval or direction of Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purpose, at a meeting of all of the Holders of Trust Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Common Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. No vote or consent of the Holders of the Common Securities will be required for the Trust to redeem and cancel Common Securities or to distribute the Subordinated Debentures in accordance with the Declaration and the terms of the Trust Securities.

7. AMENDMENTS TO DECLARATION AND INDENTURE.

(a) If any proposed amendment to the Declaration provides for, or the Regular Trustees otherwise propose to effect (i) any action that would adversely affect the powers, preferences or special rights of the Trust Securities, whether by way of amendment to the Declaration or otherwise, or (ii) the involuntary or voluntary liquidation, dissolution, winding-up or termination of the Trust, other than as described in Section 8.1 of the Declaration, then the Holders of outstanding Trust Securities as a class, will be entitled to vote on such amendment or proposal (but not on any other amendment or proposal) and such amendment or proposal shall not be effective except with the approval of the Holders of at least 66-2/3% in liquidation amount of the Trust Securities, voting together as a single class; provided that a reduction of the aggregate liquidation amount or the Distribution rate, a change in the payment dates or maturities of the Preferred Securities or a reduction in the percentage in liquidation amount of outstanding Preferred Securities, the consent of the Holders of which is required for an amendment to the

-9-

Declaration shall not be permitted without the consent of each Holder of the Preferred Securities. In the event any amendment or proposal referred to in clause (i) above would adversely affect only the Preferred Securities or only the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of 66-2/3% in liquidation amount of such class of Trust Securities.

(b) In the event the consent of the Property Trustee, as the holder of the Subordinated Debentures, the Preferred Securities Guarantee and the Common Securities Guarantee is required under the Indenture with respect to any amendment, modification, waiver or termination of the Indenture, the Subordinated Debentures, the Preferred Securities Guarantee or the Common Securities Guarantee, the Property Trustee shall request the direction of the Holders of the Trust Securities with respect to such amendment, modification, waiver or termination and shall vote with respect to such amendment, modification, waiver or termination as directed by a Majority in liquidation amount of the Trust Securities voting together as a single class; provided, however, that where a consent under the Indenture would require the consent of all of the holders of the Subordinated Debentures, the Property Trustee may only give such consent at the direction of all of the Holders of the Trust Securities; provided, further, that the Property Trustee shall not take any action in accordance with the directions of the Holders of the Trust Securities under this Section 6(b) unless the Property Trustee has obtained, at the expense of the Holders of the Trust Securities, a written opinion of a nationally recognized independent tax counsel experienced in such matters to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action.

8. PRO RATA.

A reference to any payment, distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder of applicable Trust Securities according to the aggregate liquidation amount of such Trust Securities held by the relevant Holder in relation to the aggregate liquidation amount of all applicable Trust Securities outstanding unless, in relation to a payment, an Event of Default under the Indenture has occurred and is continuing, in which case any funds available to make such payment shall be paid first to each Holder of the applicable Preferred Securities pro rata according to the aggregate liquidation amount of Preferred Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Preferred Securities outstanding, and only after satisfaction of all amounts owed to the applicable Holders of the Preferred Securities, to each applicable Holder of Common Securities pro rata according to the aggregate liquidation amount of Common Securities held by the relevant Holder relative to the aggregate liquidation amount of all applicable Common Securities outstanding.

-10-

9. RANKING.

The Preferred Securities rank pari passu and payment thereon shall be made Pro Rata with the Common Securities except that, where an Event of Default occurs and is continuing under the Indenture in respect of the Subordinated Debentures held by the Property Trustee, the rights of Holders of the Common Securities to payment in respect of Distributions and payments upon liquidation, redemption and otherwise are subordinated to the rights to payment of the Holders of the Preferred Securities.

10. ACCEPTANCE OF TRUST SECURITIES GUARANTEE AND INDENTURE.

Each Holder of Preferred Securities and Common Securities, by the acceptance thereof, agrees to the provisions of the Preferred Securities Guarantee and the Common Securities Guarantee, respectively, including the subordination provisions therein and to the provisions of the Indenture.

11. NO PREEMPTIVE RIGHTS.

SECTION 1.04. ACTS OF HOLDERS; RECORD DATES

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "ACT" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Debenture, shall be sufficient for any purpose of this Indenture and (subject to
Section 5.01) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution

- 9 -

of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

The ownership, principal amount and serial number of Debentures shall be proved by the Register.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Debenture shall bind every future Holder of the same Debenture and the Holder of every Debenture issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Debenture.

The Company may, in the circumstances permitted by the Trust Indenture Act, set any day as the record date for the purpose of determining the Holders of Outstanding Debentures entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action permitted by this Indenture to be given or taken by Holders of Debentures. With regard to any record date set pursuant to this paragraph, the Holders of Outstanding Debentures on such record date (or their duly appointed agents), and only such Persons, shall be entitled to give or take the relevant action, whether or not such Holders remain Holders after such record date. With regard to any action that may be given or taken hereunder only by Holders of a requisite principal amount of Outstanding Debentures (or their duly appointed agents) and for which a record date is set pursuant to this paragraph, the Company may, at its option, set an expiration date after which no such action purported to be given or taken by any Holder shall be effective hereunder unless given or taken on or prior to such expiration date by Holders of the requisite principal amount of Outstanding Debentures on such record date (or their duly appointed agents). On or prior to any expiration date set pursuant to this paragraph, the Company may, on one or more occasions at its option, extend such date to any later date. Nothing in this paragraph shall prevent any Holder (or any duly appointed agent thereof) from giving or taking, after any expiration date, any action identical to, or, at any time, contrary to or different from, any action given or taken, or purported to have been given or taken, hereunder by a Holder on or prior to such date, in which event the Company may set a record date in respect thereof pursuant to this paragraph.

Without limiting the foregoing, a Holder entitled hereunder to give or take any action hereunder with regard to any particular Debenture may do so with regard to all or any part of the principal amount of such Debenture or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any different part of such principal amount.

SECTION 1.05. NOTICES, ETC., TO TRUSTEE AND COMPANY

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its

- 10 -

Corporate Trust Office or sent by facsimile to the Trustee at (212) 815-5707 or at any other number previously furnished in writing to the Company by the Trustee, or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it to the attention of its Treasurer at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company or if sent to the Company by facsimile addressed to it to the attention of its Treasurer at (515) 242-4295.

SECTION 1.06. NOTICE TO HOLDERS; WAIVER

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Debentures of any event, such notice shall be sufficiently given to Holders of Debentures if in writing and mailed, first-class postage prepaid, to each Holder of a Debenture affected by such event, at his address as it appears in the Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.

In any case where notice to Holders of Debentures is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Debenture shall affect the sufficiency of such notice with respect to other Holders of Debentures given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Debentures shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 1.07. CONFLICT WITH TRUST INDENTURE ACT

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

In any case where any Redemption Date or the Maturity Date shall not be a Business Day at the Place of Payment, then (notwithstanding any other provision of this Indenture or the Debentures) payment of principal need not be made at the Place of Payment on such date, but may be made on the next succeeding Business Day at the Place of Payment with the same force and effect as if made on the respective Redemption Date or the Maturity Date, provided that no interest shall accrue for the period from and after such Redemption Date or the Maturity Date, as the case may be.

ARTICLE TWO

THE DEBENTURES

SECTION 2.01. FORM AND DATING

There is hereby authorized $979,381,450 aggregate principal amount of Debentures designated the "11% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES."

The Debentures may be issued in one or more series, provided, however, that the original principal amount of each series (other than the final series) must be at least $50,000,000 and further provided that each series has its own Series Issue Date (as defined below). There shall be

- 12 -

established in or pursuant to one or more Officer's Certificates, prior to the initial issuance of Debentures of any series, the designation of the Debentures of such series, which shall distinguish the Debentures of the series from the Debentures of all other series. All other terms of such series shall be identical and consistent with the provisions of this Indenture.

Pursuant to Section 2.11, the Debentures are to be initially issued in fully registered certificated form without interest coupons ("DEFINITIVE DEBENTURES") in the name of the Property Trustee pursuant to the Declaration on behalf of the Trust. The Debentures and the Trustee's certificate of authentication thereof shall be substantially in the form set forth in EXHIBIT A hereto, which is hereby incorporated in and made a part of this Indenture. The Debentures may have such notations, legends or endorsements as may be required by any law, rule, usage or agreement to which the Company is subject.

SECTION 2.02. MATURITY

The Maturity Date of each series will be August 31, 2011.

SECTION 2.03. PAYMENT

Principal of and interest on Definitive Debentures will be payable, the transfer of such Debentures will be registrable and such Debentures will be exchangeable for Debentures bearing identical terms and provisions, at the Corporate Trust Office of the Trustee; provided, however, that payment of interest may be made at the option of the Company by check mailed to the Holder at such address as shall appear in the Register. Notwithstanding the foregoing, so long as the Holder of the Debentures is the Property Trustee, the payment of the principal of and interest, including Deferred Interest, if any, on such Debentures held by the Property Trustee will be made in immediately available funds at such place and to such account as may be designated by the Property Trustee.

SECTION 2.04. TRANSFERABILITY

The Debentures shall be transferable only to Permitted Holders.

SECTION 2.05. INTEREST

(1) Subject to the provisions of Section 2.06, the Debentures of each series will bear interest at the rate of 11% per annum (the "INTEREST RATE") from the date of original issuance of the Debentures of such series under this Indenture (the "SERIES ISSUE DATE") until the principal thereof becomes due and payable, and on any overdue principal and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the Interest Rate, compounded semi-annually, payable (subject to the provisions of Section 2.06) semi-annually in arrears on February 28 and August 31 of each year (each, an "INTEREST PAYMENT Date"), commencing on the first such date following the date one month following the Series Issue Date, to the Person in whose name such Debenture or any predecessor Debenture is registered, at the close of business on the regular record date for such interest installment, which, in respect of any Debenture registered in the name of the Property Trustee, shall be the close of business on the Business Day next preceding that Interest Payment Date (the

- 13 -

"REGULAR RECORD DATE"). Notwithstanding the foregoing sentence, if the Debentures are not registered in the name of the Property Trustee, the Company may select a regular record date for such interest installment which shall be any date at least one Business Day before an Interest Payment Date.

(2) The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. Except as provided in the following sentence, the amount of interest payable for any period shorter than a full semi-annual period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 30-day month. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, notwithstanding the provisions of Section 1.13, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date.

(3) If at any time while the Property Trustee is the Holder of any Debentures, the Trust is required to pay any taxes, duties, assessments or governmental charges of whatever nature (other than withholding taxes) imposed by the United States, or any other taxing authority, then, in such case, the Company will pay as additional interest on the Debentures ("ADDITIONAL INTEREST"), such additional amounts as shall be required so that the net amounts received and retained by the Trust after paying such taxes, duties, assessments or other governmental charges will not be less than the amounts the Trust would have received had no such taxes, duties, assessments or other governmental charges been imposed.

SECTION 2.06. EXTENSION OF INTEREST PAYMENT PERIOD

So long as no Event of Default has occurred and is continuing, the Company shall have the right at any time, and from time to time and for varying lengths of time, during the term of the Debentures to defer payments of interest by extending the interest payment period on the Debentures for a period not exceeding 10 consecutive semi-annual periods (each, an "EXTENSION PERIOD"). Despite such deferral, semi-annual interest will continue to accumulate with interest thereon (to the extent permitted by applicable law) at an annual rate of thirteen percent (13%) per annum compounded semi-annually during any such Extension Period ("COMPOUNDED INTEREST"). At the end of the Extension Period the Company shall pay all interest accrued and unpaid on the Debentures, including any Deferred Interest that shall be payable, to the Holders of the Debentures in whose names the Debentures are registered in the Register on the first Regular Record Date after the end of the Extension Period. Prior to the termination of any Extension Period, the Company may further defer payments of interest by extending the interest payment period, provided that such Extension Period together with all such previous and further extensions thereof shall not exceed 10 consecutive semi-annual periods. Upon the termination of any Extension Period and upon the payment of all amounts then due, the Company may commence a new Extension Period, subject to the foregoing requirements. No interest shall be due and payable during an Extension Period except at the end thereof. An Extension Period with respect to any Debenture may not extend beyond the Maturity of the principal of such Debenture

- 14 -

or, as to each Debenture being optionally redeemed or, in the case of mandatory redemption, the portion thereof being redeemed, beyond the relevant Redemption Date.

SECTION 2.07. NOTICE OF EXTENSION

(1) If the Property Trustee is the only Holder of the Debentures at the time the Company selects an Extension Period, the Company shall give written notice to the Regular Trustees, and the Property Trustee of its selection of such Extension Period one Business Day prior to the earlier of

(a) the next succeeding date on which Distributions on the Trust Securities are payable and

(b) the date the Regular Trustees are required to give notice of the record date or the date such Distributions are payable to the New York Stock Exchange, Inc. (or other applicable self-regulatory organization) or to holders of the Preferred Securities, but in any event at least one Business Day before such record date.

(2) If the Property Trustee is not the only Holder of the Debentures at the time the Company selects an Extension Period, the Company shall give the Holders of the Debentures and the Trustee written notice of its selection of such Extension Period 10 Business Days prior to the earlier of
(i) the next succeeding Interest Payment Date and (ii) the date the Company is required to give notice of the record or such Interest Payment Date of such interest payment to the New York Stock Exchange, Inc. (or other applicable self-regulatory organization) or to Holders.

(3) The semi-annual period in which any notice is given pursuant to paragraphs (1) or (2) of this Section 2.07 shall be counted as one of the 10 semi-annual periods permitted in the maximum Extension Period permitted under Section 2.06.

Section 10.01.

SECTION 2.11. EXECUTION, AUTHENTICATION, DELIVERY AND DATING

- 15 -

Debentures bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Debentures.

The Company may at any time and from time to time deliver Debentures, executed by the Company, to the Trustee for authentication, together with a Company Order (attaching a form of the Debentures and the Officer's Certificate required by Section 2.01) for the authentication and delivery of such Debentures, and the Trustee in accordance with the Company Order shall authenticate and deliver such Debentures. Each Debenture shall be dated the date of its authentication. The Trustee shall be provided with and (subject to
Section 5.01) shall be fully protected in relying upon an Opinion of Counsel stating that the Debentures, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legally valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors, rights generally (including, without limitation, fraudulent conveyance laws) and by general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief regardless of whether considered in a proceeding in equity or at law.

No Debenture shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Debenture a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Debenture shall be conclusive evidence, and the only evidence, that such Debenture has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Debenture shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Debenture to the Trustee for cancellation as provided in Section 2.17, for all purposes of this Indenture such Debenture shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 2.12. TEMPORARY DEBENTURES

Pending the preparation of Definitive Debentures hereunder, the Company may execute, and upon Company Order the Trustee shall, at the expense of the Company, authenticate and deliver, temporary Debentures which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of such Definitive Debentures in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such temporary Debentures may determine, as evidenced by their execution of such temporary Debentures.

Every temporary Debenture shall be executed by the Company and authenticated by the Trustee and registered by the Registrar, upon the same conditions, and with like effect, as a Definitive Debenture.

- 16 -

If temporary Debentures are issued, the Company will cause Definitive Debentures to be prepared without unreasonable delay. After the preparation of such Definitive Debentures, the temporary Debentures shall be exchangeable for such Definitive Debentures upon surrender of the temporary Debentures at the office or agency of the Company in the Place of Payment, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Debentures, the Company shall execute and the Trustee shall, at the expense of the Company, authenticate and deliver in exchange therefor one or more Definitive Debentures, of any authorized denominations and of a like aggregate principal amount and tenor. Until so exchanged such temporary Debentures shall in all respects be entitled to the same benefits under this Indenture as Definitive Debentures.

SECTION 2.13. REGISTRATION OF TRANSFER AND EXCHANGE

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company specified therefor being herein sometimes collectively referred to as the "REGISTER") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of transfer or exchange of Debentures. The Trustee is hereby appointed "REGISTRAR" for the purpose of registering transfers or exchanges of Debentures as herein provided.

Upon surrender for registration of transfer of any Debenture at the Corporate Trust Office of the Trustee or any office or agency specified therefor by the Company, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Debentures of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

At the option of the Holder, Debentures may be exchanged for other Debentures of the same series, of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Debentures to be exchanged at such office or agency. Whenever any Debentures are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Debentures which the Holder making the exchange is entitled to receive.

All Debentures issued upon any registration of transfer or exchange of Debentures shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debentures surrendered upon such registration of transfer or exchange.

Every Debenture presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Debentures, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or

- 17 -

exchange of Debentures, other than exchanges pursuant to Section 2.12, 8.06 or 10.07 not involving any transfer.

The Company shall not be required (1) to issue, register the transfer of or exchange Debentures during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Debentures selected for redemption under Section 10.03 and ending at the close of business on the day of such mailing, or (2) to register the transfer or exchange of any Debenture so selected for redemption in whole or in part, except the unredeemed portion of any Debenture being redeemed in part.

SECTION 2.14. MUTILATED, DESTROYED, LOST AND STOLEN DEBENTURES

If any mutilated Debenture is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Debenture of the same series of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Debenture and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Debenture has been acquired by a bona fide purchaser, the Company shall execute and the Trustee, pursuant to a Company Order, shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Debenture, a new Debenture of the same series of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Debenture has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Debenture, pay such Debenture.

Upon the issuance of any new Debenture under this Section 2.14, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Debenture, issued pursuant to this Section 2.14 in lieu of any mutilated, destroyed, lost or stolen Debenture shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Debenture shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debentures duly issued hereunder.

The provisions of this Section 2.14 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures.

Each Holder of a Debenture agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder's

- 18 -

Debenture in violation of any provision of this Indenture and/or applicable United States Federal or state securities law.

The Trustees shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Debenture other than to require delivery of such certificates and other documentation or evidence as expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.15. DEFAULTED INTEREST; INTEREST RIGHTS PRESERVED

Any interest on any Debenture which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "DEFAULTED INTEREST") shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names such Debentures (or their respective Predecessor Debentures) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Debenture and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause (1) provided. Thereupon the Trustee shall fix a special record date (the "SPECIAL RECORD Date") for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment.

The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Debentures at his address as it appears in the Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Debentures (or their respective Predecessor Debentures) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) Subject to the foregoing provisions of this Section 2.15, each Debenture delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any

- 19 -

other Debenture shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debenture.

SECTION 2.16. PERSONS DEEMED OWNERS

Prior to due presentment of a Debenture for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Debenture is registered as the owner of such Debenture for the purpose of receiving payment of principal of and any interest on such Debenture and for all other purposes whatsoever, whether or not such Debenture be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 2.17. CANCELLATION

All Debentures surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Debentures previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Debentures previously authenticated hereunder which the Company has not issued and sold, and all Debentures so delivered shall be promptly canceled by the Trustee. No Debentures shall be authenticated in lieu of or in exchange for any Debentures canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Debentures held by the Trustee shall be disposed of as directed by a Company Order in accordance with the Trustee's customary procedures.

SECTION 2.18. CUSIP NUMBERS

The Company in issuing the Debentures may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Debentures or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Debentures, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers.

- 20 -

(1) either

(a) all Debentures theretofore authenticated and delivered (other than (i) Debentures which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.14, and (ii) Debentures for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in

(3) the Company has delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 5.07, the obligations of the Trustee to any Authenticating Agent under Section 5.14 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 3.01, the obligations of the Trustee under Section 3.02 and the last paragraph of Section 9.03 shall survive such satisfaction and discharge.

SECTION 3.02. APPLICATION OF TRUST MONEY

Subject to provisions of the last paragraph of Section 9.03, all money deposited with the Trustee pursuant to Section 3.01 shall be held in trust and applied by it, in accordance with the provisions of the Debentures and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and interest for whose payment such money has been deposited with the Trustee.

(1) default in the payment of any interest upon any Debenture when it becomes due and payable, and continuance of such default for a period of 10 days; provided, however, that a valid extension of the interest payment period by the Company for the Debentures in accordance with this Indenture shall not constitute a default in the payment of interest; or

(2) default in the payment of the principal of any Debenture at its Maturity; or

(3) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section 4.01 specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Debentures a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "NOTICE OF DEFAULT" hereunder; or

SECTION 4.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT

If an Event of Default with respect to Debentures at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Debentures may declare the principal amount of all of the Debentures to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to the Debentures has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Debentures, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay

(a) all overdue interest on the Debentures,

(b) the principal of any Debentures which has become due otherwise than by such declaration of acceleration and any interest thereon at the rate prescribed therefor in the Debentures,

(c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor in the Debentures, and

(2) all Events of Default with respect to the Debentures, other than the non-payment of the principal of the Debentures which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 4.13.

No such rescission or annulment shall affect any subsequent default or impair any right consequent thereon.

- 23 -

SECTION 4.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

The Company covenants that if

(1) default is made in the payment of any interest on any Debenture when such interest becomes due and payable and such default continues for a period of 10 days, or

(2) default is made in the payment of the principal of any Debenture at the Maturity thereof, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debentures, the whole amount then due and payable on such Debentures for principal and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and on any overdue interest, at the rate or rates prescribed therefor in such Debentures, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If an Event of Default with respect to the Debentures occurs and is continuing, the Trustee may in its discretion (or shall at the direction of the requisite number of Holders pursuant to Section 4.12) proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 4.04. TRUSTEE MAY FILE PROOFS OF CLAIM

In case of any judicial proceeding relative to the Company (or any other obligor upon the Debentures), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 5.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Debentures or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee.

- 24 -

SECTION 4.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBENTURES

All rights of action and claims under this Indenture or the Debentures may be prosecuted and enforced by the Trustee without the possession of any of the Debentures or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Debentures in respect of which such judgment has been recovered.

SECTION 4.06. APPLICATION OF MONEY COLLECTED

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Debentures and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 5.07;

SECOND: To the payment of the amounts then due and unpaid for principal of and interest on the Debentures in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on the Debentures for principal and interest, respectively; and

THIRD: To the Company.

SECTION 4.07. LIMITATION ON SUITS

No Holder of any Debenture shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Debentures;

(2) the Holders of not less than 25% in principal amount of the Outstanding Debentures shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request in such amount as shall be reasonably acceptable to the Trustee;

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

- 25 -

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Debentures; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

SECTION 4.08. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND INTEREST; ACKNOWLEDGMENT REGARDING PREFERRED SECURITIES HOLDERS

(1) Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the principal of and (subject to Section 2.15) interest on such Debenture, at the Maturity expressed in such Debenture and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

(2) The Company acknowledges that, with respect to any Debentures registered in the name of the Property Trustee for the benefit of the Trust, if the Property Trustee fails to enforce its rights under the Debentures and this Indenture as such Holder, then holders of Preferred Securities may institute legal proceedings directly against the Company to enforce such rights without first instituting any legal proceedings against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred under Section 4.01(1) or 4.01(2), any holder of Preferred Securities may directly institute a proceeding against the Company for enforcement of payment to such holder of the principal of or interest on the Debentures having an aggregate principal amount equal to the aggregate liquidation amount of the Preferred Securities of such holder on or after the respective due dates specified in the Debentures.

SECTION 4.09. RESTORATION OF RIGHTS AND REMEDIES

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 4.10. RIGHTS AND REMEDIES CUMULATIVE

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures in the last paragraph of Section 2.14, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be

- 26 -

cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 4.11. DELAY OR OMISSION NOT A WAIVER

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 4.12. CONTROL BY HOLDERS

The Holders of a majority in aggregate principal amount of the Outstanding Debentures shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Debentures, provided that

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3) subject to the provisions of Section 5.01, the Trustee shall have the right to decline to follow such direction if the Trustee shall, in good faith, determine that the proceeding so directed would be unjustly prejudicial to the Holders not joining in any such direction or would potentially involve the Trustee in personal liability.

SECTION 4.13. WAIVER OF PAST DEFAULTS

The Holders of not less than a majority in aggregate principal amount of the Outstanding Debentures may on behalf of the Holders of all the Debentures waive any past default hereunder with respect to the Debentures and its consequences, except a default

(1) in the payment of the principal of or interest on any Debenture, or

(2) in respect of a covenant or provision hereof which under Article Eight cannot be modified or amended without the consent of the Holder of each Outstanding Debenture affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

- 27 -

SECTION 4.14. UNDERTAKING FOR COSTS

In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs (including reasonable legal fees and expenses) against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section 4.14 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or by the Trustee.

SECTION 4.15. WAIVER OF USURY, STAY OR EXTENSION LAWS

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 4.16. THIRD PARTY BENEFICIARIES

The Property Trustee, the trustee under the Preferred Securities Guarantee and the Delaware Trustee are each a third party beneficiary of, and shall be entitled to enforce, and to exercise all rights and remedies with respect to, the provisions of Section 9.10.

ARTICLE FIVE

THE TRUSTEE

SECTION 5.01. CERTAIN DUTIES AND RESPONSIBILITIES

The duties, responsibilities, rights, immunities and protection of the Trustee shall be as provided by the Trust Indenture Act. Prior to any Event of Default the Trustee shall not be liable except for the performance of such duties as are specifically set out herein and in the Trust Indenture Act and no implied covenants or obligations shall be read into this Indenture against the Trustee. In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they substantially conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein.) Upon the occurrence of an Event of Default (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the

- 28 -

same degree of care and skill in their exercise, as a prudent individual would exercise or use under the circumstances in the conduct of his or her own affairs. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 5.01.

SECTION 5.02. NOTICE OF DEFAULTS

The Trustee shall give notice of any default actually known to a Responsible Officer of the Trustee with respect to the Debentures when, as and to the extent provided by the Trust Indenture Act and in the manner provided by
Section 1.06 hereof; provided, however, that in the case of any default of the character specified in Section 4.01(3) with respect to Debentures, no such notice to Holders shall be given until at least 30 days after the default is actually known (as set forth in Section 5.03(9)) to a Responsible Officer of the Trustee. For the purpose of this Section, the term "DEFAULT" means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Debentures.

SECTION 5.03. CERTAIN RIGHTS OF TRUSTEE

Subject to the provisions of Section 5.01:

(1) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, Officer's Certificate, statement, instrument, opinion, Opinion of Counsel, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution;

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer's Certificate;

(4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to

- 29 -

this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities (including legal fees and expenses) which might be incurred by it in compliance with such request or direction;

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney upon 10 Business Days advance written notice and during regular business hours at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation;

(7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(8) the Trustee shall not be under any obligation to take any action that is discretionary under the provisions of this Indenture;

(9) the Trustee shall not be charged with knowledge of any Event of Default unless either (i) a Responsible Officer of the Trustee shall have actual knowledge or (ii) the Trustee shall have received written notice thereof in accordance with Section 1.05(1) hereof from the Company or a Holder; and

(10) no permissive power or authority available to the Trustee shall be construed as a duty.

(11) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder, absent any gross negligence or willful misconduct.

SECTION 5.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBENTURES

The recitals contained herein and in the Debentures, except the Trustee's certificates of authentication, shall be taken as the statements of the Company, and the Trustee or any Authenticating Agent assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debentures. The Trustee or any Authenticating Agent shall not be accountable for the use or application by the Company of the Debentures or the proceeds thereof.

- 30 -

SECTION 5.05. MAY HOLD DEBENTURES

The Trustee, any Authenticating Agent, any Paying Agent, any Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Debentures and, subject to Sections 5.08 and 5.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Registrar or such other agent.

SECTION 5.06. MONEY HELD IN TRUST

Money held by the Trustee, or by any Paying Agent (other than the Company if the Company shall act as Paying Agent), in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company.

SECTION 5.07. COMPENSATION AND REIMBURSEMENT

The Company agrees

(1) to pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall be determined by a court of competent jurisdiction to have been caused by its own negligence or willful misconduct; and

(3) to indemnify the Trustee or any predecessor Trustee for, and to hold it harmless against, any and all loss, damage, liability or expense (including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder or performance of its duties hereunder, including the costs and expenses (including legal fees and expenses) of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder.

As security for the performance of the obligations of the Company under this Section 5.07, the Trustee shall have a claim prior to the Debentures upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of or interest on particular Debentures.

When the Trustee renders services or incurs expenses after the occurrence of an Event of Default specified in Sections 4.01(4) or 4.01(5) hereof, the compensation for services and

- 31 -

expenses are intended to constitute expenses of administration under any applicable bankruptcy or insolvency law or law applicable to creditors' rights to the extent permitted by applicable law.

The benefits of this Section 5.07 shall survive the termination of this Indenture and resignation or removal of the Trustee.

SECTION 5.08. DISQUALIFICATION; CONFLICTING INTERESTS

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture and the Company shall take prompt action to have a successor Trustee appointed in the manner provided herein.

SECTION 5.09. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY

There shall at all times be a Trustee hereunder, which shall be a Person that (1) is eligible pursuant to the Trust Indenture Act to act as such, and (2) has a combined capital and surplus of at least $50,000,000 and is subject to supervision or examination by a Federal or State authority; provided, however, that if the Trustee shall be a member of a bank holding company group, such bank holding company group shall have combined capital and surplus of at least $50,000,000 and the Trustee shall have a combined capital and surplus of at least $10,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 5.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

SECTION 5.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR

No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 5.11.

The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by
Section 5.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debentures, at the sole expense of the Company.

The Trustee may be removed at any time by Act of the Company or the Holders of a majority in principal amount of the Outstanding Debentures, delivered to the Trustee and to the Company.

If at any time:

- 32 -

(1) the Trustee shall fail to comply with Section 5.08 after written request therefor by the Company or by any Holder who has been a Holder of a Debenture for at least six months, or

(2) the Trustee shall cease to be eligible under Section 5.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(3) the Trustee shall become incapable of acting or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 4.14, any Holder who has been a Holder of a Debenture for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debentures of such series.

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Trustee (it being understood that any time there shall be only one Trustee) and shall comply with the applicable requirements of Section 5.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by an Act of the Holders of a majority in principal amount of the Outstanding Debentures delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of
Section 5.11, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 5.11, any Holder who has been a Holder of a Debenture for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders of Debentures in the manner provided in Section 1.06. The Company also shall give notice of appointment (and acceptance of such appointment) of a successor Trustee to the Trustee who is resigning or being removed. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

No resignation or removal pursuant to this Section 5.10 shall be effective unless and until any and all amounts due to such Trustee pursuant to Section 5.07 shall have been paid. The

- 33 -

obligations of the Company provided for in Section 5.07 shall survive such resignation or removal.

SECTION 5.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR

In case of the appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee, provided, however, that no Trustee under this Indenture shall be liable for any act or omission of any successor Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 5.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Debentures shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Debentures so authenticated with the same effect as if such successor Trustee had itself authenticated such Debentures. In the event any Debentures shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Debentures, in either its own name or that of its predecessor Trustee, with the full force and effect which this indenture provides for the certificate of authentication of the Trustee.

SECTION 5.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Debentures), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

- 34 -

SECTION 5.14. APPOINTMENT OF AUTHENTICATING AGENT

The Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Debentures issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 2.14, and Debentures so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Debentures by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall provide notice of such appointment to the Holders of Debentures, in the manner provided in Section
1.06. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

- 35 -

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 5.07.

If an appointment is made pursuant to this Section 5.14, the Debentures may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternative certificate of authentication in the following form:

Notwithstanding the provisions of this Article Eleven or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of monies to or by the Trustee in respect of the Debentures pursuant to the provisions of this Article Eleven, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder or holders of Senior Indebtedness or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 5.03, shall be entitled in all respects to assume that no such facts exist; provided, however, that, if a Responsible Officer of the Trustee shall not have received the notice provided for in this Section 11.06 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose

The Trustee, subject to the provisions of Section 5.03, shall be entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness of the Company, as the case may be (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee on behalf of any such holder or holders.

The Trustee or any Authenticating Agent in its individual capacity shall be entitled to all the rights set forth in this Article Eleven in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article Eleven, and no implied covenants or obligations with respect to the holders of such Senior Indebtedness shall be read into this Indenture against the Trustee.

SECTION 11.08. SUBORDINATION MAY NOT BE IMPAIRED

No right of any present or future holder of any Senior Indebtedness of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company, or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company, as the case may be, with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with.

- 51 -

Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness of the Company may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination provided in this Article Eleven or the obligations hereunder of the Holders to the holders of such Senior Indebtedness, do any one or more of the following: (1) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding; (2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness; (3) release any Person liable in any manner for the collection of such Senior Indebtedness; and (4) exercise or refrain from exercising any rights against the Company, as the case may be, and any other Person.

Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

11% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE, SERIES __, DUE ____

MidAmerican Energy Holdings Company, an Iowa corporation (the "Company"), which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to __________________, or registered assigns, the principal sum of __________________ Dollars on ______________, ____, subject to mandatory redemption in nine annual principal installments, commencing ________, as more fully described on the reverse hereof, together with any accrued and unpaid interest thereon, including any Deferred Interest, and to pay interest on said principal sum from ____________, ____, or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semi-annually (subject to deferral as set forth herein) in arrears on February 28 and August 31 of each year (each such date, an "Interest Payment Date") commencing __________, ____, at the rate of 11% per annum until the principal hereof shall have become due and payable, and on any overdue principal and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum compounded semi-annually. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed on the basis of the actual number of days elapsed per 30-day month. In the event that any date on which interest is payable on this Debenture is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Debenture (or one or more Predecessor Debentures, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment, which shall be the close of business on the Business Day next preceding such Interest Payment Date. [IF THE PROPERTY TRUSTEE IS NO LONGER THE HOLDER OF THE DEBENTURES -- which shall be the close of business on the ___ Business Day next


preceding such Interest Payment Date.] Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such regular record date and may be paid to the Person in whose name this Debenture (or one or more Predecessor Debentures) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of the Debentures not less than 10 days prior to such special record date. The principal of and the interest on this Debenture shall be payable at the Corporate Trust Office of the Trustee maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Debenture Register. Notwithstanding the foregoing, so long as the Holder of this Debenture is the Property Trustee, the payment of the principal of and interest on this Debenture will be made at such place and to such account as may be designated by the Property Trustee.

The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness of the Company, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

Unless the Certificate of Authentication hereon has been executed by the Trustee referred to on the reverse side hereof, this Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

The provisions of this Debenture are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

IN WITNESS WHEREOF, the Company has caused this instrument to be executed.

CERTIFICATE OF AUTHENTICATION

This is one of the Debentures described in the within-mentioned Indenture.

THE BANK OF NEW YORK

By: ________________________________________ Authorized Signatory


(FORM OF REVERSE OF DEBENTURE)

This Debenture is one of the duly authorized Debentures of the Company (herein sometimes referred to as the "Debentures"), all issued under and pursuant to an Indenture dated as of August 16, 2002, (the "Indenture") duly executed and delivered between the Company and The Bank of New York, as Trustee (the "Trustee"), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Debentures. The Debentures are issuable in series (this Debenture being of the series specified on the front hereof) in an aggregate principal amount not exceeding $979,381,450. The Debentures of this series are subject to mandatory redemption in nine annual principal installments, with the first installment equal to 15.789474% of the original aggregate principal amount of Debentures of this series and payable on the first Interest Payment Date which is at least one year following the Series Issue Date, and each following installment equal to 10.526316% of such original aggregate principal amount and payable on each August 31 Interest Payment Date thereafter with the last installment payable on the Maturity Date.

The Company shall also have the option to redeem this Debenture, at any time in certain circumstances upon the occurrence of a Special Event, at a redemption price equal to 100% of the principal amount plus any accrued but unpaid interest to the date of such redemption (the "Redemption Price"). Any Special Event Redemption pursuant to this paragraph will be made upon not less than 30 nor more than 60 days' notice at the Redemption Price. If the Debentures are only partially redeemed by the Company pursuant to a mandatory redemption, the Debentures of this series will be redeemed pro rata.

In the event of redemption of this Debenture in part only, a new Debenture of the same series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Debentures may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Debentures affected at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Debentures; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of the Debentures, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, without the consent of the Holder of each Debenture so affected, or (ii) reduce the aforesaid percentage of Debentures, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Debenture then outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Debentures at the time outstanding affected thereby, on behalf of all of


the Holders of the Debentures, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to the Debentures, and its consequences, except a default in the payment of the principal of or interest on any of the Debentures. Any such consent or waiver by the registered Holder of this Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Debenture and of any Debenture issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Debenture.

No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Debenture at the time and place and at the rate and in the money herein prescribed.

The Company shall have the right at any time during the term of the Debentures from time to time to extend the interest payment period of such Debentures to up to 10 consecutive six-month payment periods (an "Extension Period"); provided that an Extension Period may not extend beyond the Maturity Date or, as to each Debenture being optionally redeemed or, in the case of mandatory redemption, the portion thereof being redeemed, beyond the relevant Redemption Date. At the end of any such Extension Period, the Company shall pay all interest then accrued and unpaid (together with interest thereon at the rate specified for the Debentures to the extent that payment of such interest is enforceable under applicable law). Before the termination of any such Extension Period, the Company may further extend such Extension Period, provided that such Extension Period together with all such further extensions thereof shall not exceed 10 consecutive six-month payment periods. At the termination of any such Extension Period and upon the payment of all accrued and unpaid interest and any additional amounts then due, the Company may commence a new Extension Period.

As provided in the Indenture and subject to certain limitations therein set forth, this Debenture is transferable under limited circumstances by the registered Holder hereof on the Register of the Company, upon surrender of this Debenture for registration of transfer at the office or agency of the Company in ____________________ accompanied by a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Debentures of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Debenture, the Company, the Trustee, any paying agent and any Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Registrar shall be affected by any notice to the contrary.

- 2 -

No recourse shall be had for the payment of the principal of or the interest on this Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

The Debentures are issuable only in definitive form without coupons in denominations of $25 and any integral multiple thereof. Debentures so issued are issuable only in registered form without coupons in denominations of $25 and any integral multiple thereof as provided in the Indenture and subject to certain limitations herein and therein set forth. Debentures so issued are exchangeable for a like aggregate principal amount of Debentures of the same series of a different authorized denomination, as requested by the Holder surrendering the same.

All terms used in this Debenture that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The undersigned further understands that for purposes of determining whether this 25% threshold has been met or exceeded, the value of any equity interests held by a person (other than a benefit plan investor) who has discretionary authority or control with respect to the assets of the entity, or any person who provides investment advice for a fee (direct or indirect) with respect to such assets, or any affiliate of such a person, is disregarded:

Yes X No

Section 4 and of performing the obligations they undertake hereunder.

David Scott Wyoming Trust, Karen Ann Dixon Wyoming Trust, Double Eight Land Corporation (the "Scott Family Entities") and David L. Sokol and Gregory E. Abel whose names and addresses appear on Schedule I hereto (the "Management Investors," and, together with Berkshire, Scott and the Scott Family Entities, the "Investors"); and Teton Acquisition Corp., an Iowa corporation (the "Company"). Certain terms used in this Agreement are defined in Section 7 hereof. This Agreement shall become effective upon the consummation of the Merger.

R E C I T A L S

WHEREAS, pursuant to the terms of certain Subscription Agreements with the Company (the "Subscription Agreements") and the Agreement and Plan of Merger dated as of October 24, 1999, by and among MidAmerican Energy Holdings Company, Teton Formation L.L.C. and the Company (the "Merger Agreement"), (i) Berkshire will purchase shares of Common Stock, no par value, of the Company ("Common Stock"), shares of Zero Coupon Convertible Preferred Stock, no par value, of the Company ("Convertible Preferred Stock") and Trust Preferred Securities of MidAmerican Capital Trust, a Delaware statutory business trust; (ii) Scott and the Scott Family Entities will purchase shares of Common Stock; and (iii) the Management Investors will purchase shares of Common Stock and options to purchase Common Stock (together with any other options to purchase Common Stock issued to the Management Investors on the date hereof, the "Options");

WHEREAS, the Investors and the Company desire to promote their mutual interests by agreeing to certain matters relating to the disposition of the shares of Common Stock, Convertible Preferred Stock and Options owned by the Investors on the date hereof, together with any other shares of Common Stock or Convertible Preferred Stock or Options subsequently acquired or otherwise owned by them from time to time (collectively, the "Securities"), as further set forth herein; and

WHEREAS, pursuant to the Merger Agreement, the Company will merge with and into MidAmerican Energy Holdings Company (the "Merger"), with the surviving corporation being referred to herein as the Company;

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, the parties hereto hereby agree as follows:

1. COVENANTS OF THE PARTIES

(a) Legends. The certificates evidencing the Securities owned or acquired by the Investors or their permitted transferees will bear the following legends reflecting the restrictions on the transfer of such securities under the Securities Act and those contained in this Agreement:


"The securities evidenced hereby have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), and may not be transferred except pursuant to an effective registration under the Securities Act or in a transaction which, in the opinion of counsel reasonably satisfactory to MidAmerican Energy Holdings Company (the "Company"), qualifies as an exempt transaction under the Securities Act and the rules and regulations promulgated thereunder.

The securities evidenced hereby are subject to the terms of that certain Shareholders Agreement, dated as of March 14, 2000, by and among the Company and certain holders of securities of the Company, including, as applicable, certain restrictions on transfer and certain rights of first refusal. A copy of such Shareholders Agreement has been filed with the Secretary of the Company and is available upon request."

(b) Additional Management Investors. The parties hereto acknowledge that, subject to the terms hereof, certain Management Permitted Transferees (as defined below in Section 2(a)) may become shareholders of the Company after the date hereof pursuant to Section 2(a) and that each Management Permitted Transferee will be required, as a condition to the Transfer of Securities to them, to execute a Joinder Agreement in the form attached hereto as Exhibit A (the "Joinder Agreement"). Upon execution of a Joinder Agreement, each such Management Permitted Transferee shall be deemed to be a Management Investor under this Agreement and shall be entitled to all of the rights and benefits afforded to, and shall be subject to all the restrictions on and obligations of, a Management Investor hereunder.

(c) Additional Investors. The parties hereto acknowledge that, subject to the terms hereof, certain third parties may become shareholders of the Company pursuant to the Permitted Transfers set forth in Section 2(b) after the date hereof and that each such permitted transferee will be required, as a condition to the Transfer of Securities to them, to execute a Joinder Agreement. Upon execution of a Joinder Agreement, each such Person shall be deemed to be an Investor under this Agreement and shall be subject to all the restrictions on and obligations of, an Investor hereunder. Upon execution of a Joinder Agreement, each such Scott Entity who becomes a shareholder pursuant to Section 2(b)(i) shall be entitled to all of the rights and benefits afforded to, and shall be subject to all the restrictions on and obligations of, a Scott Entity hereunder. Upon execution of a Joinder Agreement, each such Scott Family Entity Permitted Transferee shall be deemed to be a Scott Family Entity under this Agreement and shall be entitled to all of the rights and benefits afforded to, and shall be subject to all the restrictions on and obligations of, a Scott Family Entity hereunder.

(d) Amendment No. 1 to David L. Sokol's Employment Agreement. Contemporaneously with the execution of this Agreement, the Company and David L. Sokol shall enter into Amendment No. 1 to the existing Amended and Restated Employment Agreement between MidAmerican Energy Holdings Company and David L. Sokol, which amendment shall be substantially in the form set forth on Exhibit B hereto.

2

(e) Voting Agreement Regarding Restated Articles of Incorporation.

(i) The Company shall immediately after the Merger, call and hold a special meeting of the Company's shareholders. At such meeting, the Investors shall vote all of their Securities in favor of the adoption of Restated Articles of Incorporation in the form set forth in Exhibit C hereto.

(ii) EACH OF THE INVESTORS HEREBY GRANTS TO, AND APPOINTS DAVID L. SOKOL AND MARC D. HAMBURG, THE INVESTOR'S IRREVOCABLE PROXY AND ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION) TO VOTE THE SECURITIES OF THE INVESTORS AT THE SPECIAL MEETING AND IN RESPECT OF THE MATTER IDENTIFIED IN SECTION 1(e)(i) ABOVE AND TO WAIVE NOTICE OF THE SPECIAL MEETING. EACH OF THE INVESTORS INTEND THIS PROXY TO BE IRREVOCABLE AND COUPLED WITH AN INTEREST AND SHALL TAKE SUCH FURTHER ACTIONS AND EXECUTE SUCH OTHER INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY AND HEREBY REVOKES ANY PROXY PREVIOUSLY GRANTED BY SUCH INVESTOR WITH RESPECT TO THE SECURITIES OWNED BY SUCH INVESTOR.

(iii) The Company shall file the Restated Articles of Incorporation adopted by the Company's shareholders with the Secretary of State of Iowa.

2. TRANSFER OF STOCK

(a) Resale of Management Investors' Securities. Except as otherwise provided in Section 3, until the third anniversary of the date hereof, no Management Investor shall Transfer any Securities, or any beneficial interest therein, other than to such Management Investor's estate, spouse, lineal descendants or any Qualified Trusts for the benefit of such Management Investor or the foregoing persons or non-corporate charitable foundations controlled by such Management Investor (collectively, "Management Permitted Transferees"). For the avoidance of doubt, this Section 2(a) is not intended to diminish any transfer restrictions contained in any option agreement governing the Options. The Transfer restrictions contained in this Section 2(a) shall terminate upon a Berkshire Majority Transfer.

(b) Resale of Scott's, Scott Entities' and Scott Family Entities' Securities. Except as otherwise provided in Section 3 and except for Permitted Transfers (as defined below), Scott, his Qualified Trusts, his estate (including a grantor Qualified Trust created by him to receive his probate estate and distributions by such Qualified Trust to a non-corporate foundation created by him) and any charitable Qualified Trust or non-corporate foundation controlled as to voting by him (collectively, the "Scott Entities") and the Scott Family Entities shall not Transfer the Retained Shares or the Additional Shares other than, as applicable, to the individual beneficiaries of those of the Scott Family Entities which are trusts (such individuals, hereinafter, the "Trust Individuals") or the respective estates, spouses and lineal descendants of such Trust Individuals or any Qualified Trusts for the benefit of such spouses or lineal descendants of such Trust Individuals or non-corporate charitable foundations controlled by such Scott Family Entities (collectively, "Scott Family Entity Permitted Transferees"). "Permitted Transfers" shall mean (i) (x) Transfers between or among the Scott Entities, (y) Transfers between or among the

3

Scott Family Entities or (z) Transfers by the Scott Family Entities to the Scott Entities, (ii) Transfers of the Retained Shares at any time after the fifth anniversary of the date hereof and of the Additional Shares at any time after the third anniversary of the date hereof to Eligible Purchasers in compliance with the provisions of Sections 2(d) through 2(j), (iii) Transfers made at any time pursuant to the Scott Put provided for in Section 4(c), and (iv) other Transfer arrangements agreed upon by Scott and Berkshire which would not cause either Scott or Berkshire or any of their affiliates to become subject to regulation as a registered holding company under PUHCA or cause the Company or any of its subsidiaries to become subject to regulation as a subsidiary of a registered holding company under PUHCA. The Transfer restrictions contained in this Section 2(b) shall terminate upon a Berkshire Majority Transfer.

(c) Statutory Transfer Restrictions. No Investor shall Transfer any Securities (including any Securities received as a result of dividends, splits or any other forms of recapitalization in respect of such Securities), either voluntarily or involuntarily, directly or indirectly, except pursuant to an effective registration under the Securities Act, or in a transaction which qualifies as an exempt transaction under the Securities Act and the rules and regulations promulgated thereunder. No Investor shall Transfer any Securities (including any Securities received as a result of dividends, splits or any other forms of recapitalization in respect of such Securities) in violation of PUHCA.

(d) Rights of First Refusal. Except as otherwise permitted by clauses
(i), (iii) and (iv) of the definition of Permitted Transfers contained in
Section 2(b) and as otherwise permitted by Section 3, none of Scott, any of the Scott Entities or any of the Scott Family Entities shall Transfer any Retained Shares or Additional Shares or any shares of Common Stock received in exchange therefor, or any beneficial interest therein, unless such Investor desiring to make the Transfer (hereinafter referred to as the "Transferor") shall have first made the offer to sell to Berkshire as contemplated by Sections 2(d) through
2(k), and such offers shall not have been accepted in the manner set forth below or shall not have been timely paid for in the manner set forth below.

(e) Offer by Transferor. Transferor shall provide written notice to Berkshire of Transferor's intent to make a Transfer subject to Section 2(d), which written notice shall include an offer to sell to Berkshire all of the shares of Common Stock then proposed to be transferred by the Transferor (the "Subject Shares") and a certification that the Proposed Transfer would be made pursuant to a bona fide offer of a third party, identification of the name and address of such third party transferee, the number of shares of Common Stock involved in the proposed Transfer and the material terms of such offer.

(f) Acceptance of Offer.

(i) If Berkshire is an Eligible Purchaser at the time of receipt of the offer described in Section 2(e), within ten (10) days after the receipt of the offer described in Section 2(e), Berkshire may, at its option, elect to purchase all, but not less than all, of the Subject Shares. Berkshire shall exercise such option by giving written notice thereof to the Transferor within such 10-day period, which notice shall specify a date for the closing of the purchase which shall not be more than thirty (30) days after the date of the giving of such notice, or, if applicable and required by law, two business days after the later of (A) the expiration or

4

termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder, (B) the receipt of any orders or approvals required by any federal or state regulatory authority, and (C) the receipt of any orders or approvals or the expiration without action of any waiting period required by any European or United Kingdom competition authority;

(ii) If Berkshire is not an Eligible Purchaser at the time of receipt of the offer described in Section 2(e), within forty-five (45) days after the receipt of the offer described in Section 2(e), Berkshire may, at its option, elect to assign its rights to purchase the Subject Shares pursuant to this
Section 2 to one or more Eligible Purchasers (each, an "Assignee"); provided that such Assignee(s) agree in writing to purchase the Subject Shares in accordance with the terms of this Agreement. Berkshire or its Assignee(s) shall exercise such option by giving written notice to the Transferor within such 45-day period, which notice shall specify the purchaser or purchasers of the Subject Shares, a date for the closing of the purchase which shall not be more than thirty (30) days after the date of the giving of such notice, or, if applicable and required by law, two (2) business days after the later of (A) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder, (B) the receipt of any orders or approvals required by any federal or state regulatory authority, and (C) the receipt of any orders or approvals or the expiration without action of any waiting period required by any European or United Kingdom competition authority.

(g) Purchase Price. The purchase price per share for the Subject Shares shall be the price per share offered to be paid by the prospective transferee described in the offer, which price shall be paid in cash or, if so provided in the offer of the prospective transferee, cash plus deferred payments of cash in the same proportions, and with the same terms of deferred payment as therein set forth.

(h) Consideration Other Than Cash. If the offer of Subject Shares under this Section 2 is for consideration other than cash or cash plus deferred payments of cash, Berkshire (or its Assignee(s)) shall pay the cash equivalent of such other consideration. If the Transferor and Berkshire (or its Assignee(s)) cannot agree on the amount of such cash equivalent within the 10-day period or the 45-day period, as applicable, under Section 2(f), either of such parties may, by written notice to the other given before the end of that period, initiate appraisal proceedings under Section 2(i) for determination of the cash equivalent.

(i) Appraisal Procedure. If any party shall initiate appraisal proceedings to determine the amount of the cash equivalent of any consideration for Subject Shares under Section 2(h), then the Transferor, on the one hand, and Berkshire or its Assignee(s), on the other hand, shall each promptly (and in any event within ten (10) days of the expiration of the 10-day or 45-day period, as applicable) appoint as an appraiser an individual who shall be a member of a reputable valuation firm or investment bank. Each appraiser shall, within thirty
(30) days of appointment, separately determine the value of the consideration for the Subject Shares as of the proposed transfer date and shall submit a written determination of value to each party. Each appraiser shall determine such value without regard to income tax consequences to the Transferor as a result of receiving cash rather than other consideration. If, upon the completion of the initial appraisals (the "Earlier Appraisals"), the higher appraised value of such

5

consideration is not more than one hundred ten percent (110%) of the lower appraised value of such consideration, the average of the two appraisals on a per share basis shall be controlling as the amount of the cash equivalent. If the higher appraised value is more than one hundred ten percent (110%) of the lower appraised value, the appraisers, within ten (10) days of the submission of the last appraisal, shall appoint a third appraiser who shall be a member of a reputable valuation firm or investment bank. The third appraiser shall, within thirty (30) days of his appointment, appraise the value of the consideration for the Subject Shares (without regard to the income tax consequences to the Transferor as a result of receiving cash rather than other consideration) as of the proposed transfer date and submit a written determination of value to each party. The value determined by the third appraiser shall be controlling as the amount of the cash equivalent unless the value is greater than the two Earlier Appraisals, in which case the higher of the two Earlier Appraisals will control, and unless that value is lower than the two Earlier Appraisals, in which case the lower of the two Earlier Appraisals will control. If any party fails to appoint an appraiser or if one of the two initial appraisers fails after appointment to submit his appraisal within the required period, the appraisal submitted by the remaining appraiser shall be controlling. The cost of the foregoing appraisals shall be shared one-half by the Transferor and one-half by Berkshire or its Assignee(s).

(j) Closing of Purchase. The closing of the purchase shall take place at the office of the Company or such other location as shall be mutually agreeable and the purchase price, to the extent comprised of cash, shall be paid at the closing, and cash equivalents and documents evidencing any deferred payments of cash permitted pursuant to Section 2(g) above shall be delivered at the closing. At the closing, the Transferor shall deliver to Berkshire or its Assignee(s), as the case may be, the certificates evidencing the Subject Shares to be conveyed, duly endorsed and in negotiable form with all the requisite documentary stamps affixed thereto.

(k) Release from Restriction; Termination of Rights. If the offer pursuant to Section 2(e) is not timely accepted by Berkshire or its Assignee(s) pursuant to Section 2(f) hereof or is not timely paid for by Berkshire or its Assignee(s) in accordance with Sections 2(f) and (j) hereof, then the Transferor may make a bona fide Transfer to the prospective transferee named in the certification included in the offer in accordance with the terms set forth therein, provided, that such Transfer shall be made only in strict accordance with the terms therein stated. If Berkshire or its Assignee(s) do not elect to purchase as provided in Section 2(f) and the Transferor shall fail to make such Transfer within sixty (60) days following the expiration of the time hereinabove provided for the acceptance by Berkshire or its Assignee(s), such shares of Common Stock shall again become subject to all the restrictions of this Section
2. If Berkshire elects to purchase as provided in Section 2(f), but the purchase is not timely paid for by Berkshire (or its Assignee(s)) in accordance with Sections 2(f) and (j) hereof, then the Subject Shares shall be released from all restrictions under this Section 2.

(l) Ownership Limitation. No Investor shall own shares of Common Stock equal to or in excess of the Ownership Limit. No Investor shall Transfer any Securities which shall cause any Person (together with its Affiliates) to own shares of Common Stock equal to or in excess of the Ownership Limit. Notwithstanding the foregoing, if the exercise of a Put or Call would cause a holder of Convertible Preferred Stock and its Affiliates to own shares of Common Stock equal to or in excess of the Ownership Limit, then, pursuant to the terms of its Restated Articles of Incorporation, the Company shall accept and such holder or its Affiliates shall tender

6

for exchange that number of shares of Common Stock and the Company shall issue the equivalent number of shares of Convertible Preferred Stock to such holder or its Affiliates, as the case may be, so that such holder and its Affiliates will not own shares of Common Stock equal to or in excess of the Ownership Limit.

(m) Prohibited Transfers. Any Transfer or purported Transfer made in violation of this Section 2 shall be null and void and of no effect.

3. TAG-ALONG RIGHT

In the event that Berkshire or any of its consolidated subsidiaries intends to Transfer (other than to one or more of Berkshire's consolidated subsidiaries) shares of Common Stock or Convertible Preferred Stock which, together with any previous Transfers (other than Transfers within Berkshire's consolidated group of companies) of shares of Common Stock or Convertible Preferred Stock by Berkshire or its consolidated subsidiaries from and after the date of this Agreement, represent more than fifty percent (50%) of the Common Stock (calculated on a fully-diluted basis assuming conversion of the Convertible Preferred Stock) held by Berkshire and its consolidated subsidiaries on the date hereof, Berkshire shall notify the other Investors, in writing, of such proposed Transfer and its price terms and conditions (the "Proposed Sale"). Following receipt of such a notice, any of Scott, the Scott Entities, the Scott Family Entities and the Management Investors ("Eligible Investors") shall have the right to exercise the tag-along right described in this Section 3. Within ten (10) days of the date of receipt of such notice delivered under Section
8(a), each Eligible Investor that elects to participate in the Proposed Sale shall so notify receipt of Berkshire in writing (a "Transfer Notice," all Eligible Investors who give such Transfer Notice being the "Tag-Along Investors"). In the event Berkshire fails to receive a Transfer Notice from any Eligible Investor within such 10-day period, such Eligible Investor shall have no right to participate in the Proposed Sale. Each Tag-Along Investor delivering a Transfer Notice shall have the right to sell, at the same price and on the same terms as Berkshire, that number of shares of Common Stock equal to the number of shares of Common Stock (assuming that all Convertible Preferred Stock shall be considered on an as-converted basis as Common Stock) the third party proposes to purchase multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock (assuming that all Options shall be considered on an as-exercised basis as Common Stock) issued and owned by such Tag-Along Investor and the denominator of which shall be the aggregate number of shares of Common Stock issued and owned by Berkshire (assuming that all Convertible Preferred Stock shall be considered on an as-converted basis as Common Stock) and each Tag-Along Investor (including such Tag-Along Investor exercising its rights under this Section 3). Nothing contained herein shall obligate Berkshire to consummate the Proposed Sale or limit Berkshire's right to amend or modify the terms of the Proposed Sale in any respect; provided that the Tag-Along Investors are offered the opportunity to participate in the Proposed Sale on such amended or modified terms. The tag-along rights described in this
Section 3 shall terminate upon a Berkshire Majority Transfer.

4. PUTS AND CALLS

(a) The Management Put. At any time after the earlier of (i) the third anniversary of the date hereof, (ii) a Berkshire Majority Transfer or (iii) the death of David L.

7

Sokol or Gregory E. Abel, each Management Investor (in the case of clauses (i) and (ii)), and the estate of David L. Sokol or Gregory E. Abel, as applicable, in the case of clause (iii), shall have the right to require the Company to purchase, and the Company at the time of any such put shall be obligated to purchase from the Management Investors (or the estate of David L. Sokol or Gregory E. Abel, as applicable), upon the terms and subject to the conditions of this Agreement, not less than twenty-five percent (25%) and up to one hundred percent (100%) of the Securities owned at that time by such Management Investor (the "Management Put") at the Purchase Price; provided, however, that a Management Investor may exercise a Management Put as to his or her Securities only once in any twelve (12) month period. If a Management Investor wishes to exercise the Management Put, the Management Investor shall provide written notice to such effect and specifying the number and type of Securities to be put to the Company (the "Management Put Notice").

(b) The Company Call on Management Securities. At any time after the earlier of the third anniversary of the date hereof or a Berkshire Majority Transfer, the Company shall have the right to purchase from any or all of the Management Investors, and the Management Investors designated by the Company at the time of any such call shall be obligated to sell to the Company, upon the terms and subject to the conditions of this Agreement, not less than twenty-five percent (25%) and up to one hundred percent (100%) of the Securities owned at that time by any such Management Investor so designated by the Company (the "Management Call") at the Purchase Price; provided, however, that the Company may exercise a Management Call as to any Management Investor-owned Securities only once in any twelve (12) month period. If the Company wishes to exercise the Management Call, the Company shall provide written notice to the designated Management Investors specifying the number and type of Securities to be called by the Company (the "Management Call Notice").

(c) The Scott, Scott Entities and Scott Family Entities Put. At any time following the third anniversary of the date hereof, and provided in any such case that Berkshire is then an Eligible Purchaser, any or all of Scott, the Scott Entities and the Scott Family Entities shall have the right to require Berkshire to purchase, upon the terms and subject to the conditions of this Agreement, any or all of the shares of Common Stock owned by such persons and entities at the Purchase Price (the "Scott Put"); provided, however, that any or all of Scott, the Scott Entities and the Scott Family Entities may choose to receive shares of Berkshire common stock equal in value to the Purchase Price, which value shall be the closing price quoted on the New York Stock Exchange on the day immediately preceding the closing (which Berkshire shall register for resale by filing an S-3 Registration Statement with respect to such shares if the value thereof exceeds $15 million) in exchange for shares of Common Stock so put by them (in lieu of the cash Purchase Price). In the event that any such persons or entities elect to exercise the Scott Put, then such persons or entities shall provide written notice to Berkshire specifying the number of shares of Common Stock to be put by them and whether they choose to receive the Purchase Price in cash or shares of Berkshire common stock (a "Scott Put Notice"). The Scott Put shall terminate upon a Berkshire Majority Transfer.

(d) The Purchase Price. The purchase price payable pursuant to Section
4(a), (b) or (c) above shall be payable in cash except as provided in Section 4(c) above. With respect to any shares of Common Stock subject to any Management Put, Management Call or Scott Put, the purchase price shall equal the applicable number of shares multiplied by the purchase price

8

per share, which shall be the fair market value of a share of Common Stock assuming the Company is valued on a going-concern basis as though it were a publicly traded company with reasonable liquidity and without a controlling shareholder and without attributing any change of control premium to the sale of such share, and taking into account all aspects of the Company's capital structure including all outstanding options. With respect to any Options subject to any such Management Put or Scott Put, the purchase price shall be determined as if the Options had been exercised, with the purchase price per share determined as described above, and reduced by the applicable exercise price or prices. With respect to any Options subject to any such Management Call, the purchase price determined as described in the immediately preceding sentence shall be increased to the extent required to reflect the loss of the remaining time value of the Options. The applicable purchase price as determined pursuant to this Section 4(d) is referred to as the "Purchase Price."

(e) Determination of the Purchase Price for the Management Put or Management Call. As soon as reasonably practicable, but in any event within fifteen (15) days, following the delivery of a Management Put Notice or a Management Call Notice, the Company shall prepare and deliver to each selling Management Investor a statement setting forth the good faith calculation of the Purchase Price as of the date of the notice, together with detail reasonably sufficient for such Management Investor(s) to evaluate the accuracy of such calculation (the "Purchase Price Statement"). Unless any Management Investor, within fifteen (15) days after receipt of the Purchase Price Statement, delivers to the Company a notice (the "Dispute Notice"): (i) objecting in good faith to the Purchase Price Statement, (ii) setting forth in reasonable detail the items being disputed and the reasons therefor and (iii) specifying such Management Investor's preliminary calculation of the Purchase Price as of the date of the Put Notice or the Call Notice, as applicable, the Purchase Price Statement shall be deemed to be final, and the Purchase Price set forth therein shall be deemed to be the "Final Purchase Price". If a Management Investor delivers a Dispute Notice and if the Company and such Management Investor(s) are unable to agree upon a Final Purchase Price within thirty (30) days of the date of the Dispute Notice, then either the selling Management Investor or the Company may elect to submit the calculation of the Purchase Price to an independent appraiser who shall be a member of a reputable valuation firm or investment bank which is designated jointly by the Company and such Management Investor(s); provided, however, that the Company and the Management Investors (as a group) may each only exercise this right to seek an appraisal once in any twelve (12) month period. Such appraiser shall determine the Purchase Price at the date of the Management Put Notice or Management Call Notice, as applicable, and such Purchase Price shall be deemed to be the Final Purchase Price. If the appraisal results from a Management Put Notice or a Management Call Notice, within thirty
(30) days of the determination of the Final Purchase Price by the appraiser, (i) any Management Investor, including the Management Investor making the initial request, may elect to exercise its Management Put to sell Securities to the Company for the Final Purchase Price and (ii) the Company may elect to exercise the Management Call to purchase Securities from any Management Investor for the Final Purchase Price. If the Management Put is exercised pursuant to the preceding sentence by any Management Investor, then the Management Investors (as a group) shall have no further right to request an appraisal for a twelve (12) month period in connection with a Management Put or Management Call. If the Management Call is exercised pursuant to the preceding sentence, then the Company shall have no further right to request an appraisal for a twelve (12) month period in connection with a Management Put or Management Call.

9

(f) Determination of the Purchase Price for the Scott Put. As soon as reasonably practicable following the delivery of a Scott Put Notice, Berkshire shall prepare and deliver to each of Scott, the Scott Entities and the Scott Family Entities which delivered a Scott Put Notice a Purchase Price Statement. Unless the selling party, within ten (10) days after receipt of the Purchase Price Statement, deliver to Berkshire a Dispute Notice: (i) objecting in good faith to the Purchase Price Statement, (ii) setting forth in reasonable detail the items being disputed and the reasons therefor and (iii) specifying such party's calculation of the Purchase Price as of the date of the Scott Put Notice, the Purchase Price Statement shall be deemed to be final, and the Purchase Price set forth therein shall be deemed to be the "Final Purchase Price". If the selling party or parties deliver a Dispute Notice and if the selling party or parties and Berkshire are unable to agree upon a Final Purchase Price within thirty (30) days of the Dispute Notice, then the selling party or parties may elect to submit the calculation of the Purchase Price to an independent appraiser who shall be a member of a reputable valuation firm or investment bank which is designated jointly by the selling party or parties and Berkshire; provided, however, that Scott, the Scott Entities and the Scott Family Entities (as a group) may only exercise this right to seek an appraisal once every twelve (12) months (and such appraisal shall be available only to the party or parties selling contemporaneously with the delivery of the appraisal). Such appraiser shall determine the Final Purchase Price at the date of the Scott Put Notice and such Purchase Price shall be deemed to be the Final Purchase Price.

(g) Closing of Purchases. The closing of the purchases pursuant to this Section 4 shall take place at the office of the Company or such other location as shall be mutually agreeable on a date three (3) days after the determination of the Final Purchase Price or, if applicable and required by law, two (2) business days after the later of (i) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (ii) the receipt of any orders or approvals required by any federal or state regulatory authority, and (iii) the receipt of any orders or approvals or the expiration without action of any waiting period required by any European or United Kingdom competition authority. The purchase price shall be paid at the closing. At the closing, the selling Investor shall deliver to the purchasing party the certificates evidencing the Securities to be conveyed, duly endorsed and in negotiable form with all requisite documentary stamps affixed thereto.

5. COMPANY COVENANTS

(a) Appraisals. The Company shall engage an independent appraiser who shall be a member of a reputable valuation firm or investment bank to appraise the value of the Company's Common Stock as of December 31, 2002 based on information deemed relevant by the valuation firm or investment bank, valued on a going-concern basis as though it were a publicly traded company with reasonable liquidity and without a controlling shareholder and without attributing any change of control premium to the sale of shares, and taking into account all aspects of the Company's capital structure including all outstanding options. Such appraisal shall promptly (but in no event later than April 30, 2003) be delivered by the Company to the Investors.

Sokol (the "Executive"), is entered into as of March __, 2000.

WHEREAS, the Company and the Executive are presently parties to the Employment Agreement; and

WHEREAS, in consideration of the performance of future services by the Executive, the Company and the Executive desire to amend the Employment Agreement to increase the Executive's salary, and grant Executive additional options;

NOW, THEREFORE, the Employment Agreement is hereby amended as follows:

By inserting immediately following Section 2(b) a new Section 2(c) to read as follows:

"(c) For so long as the Executive continues to serve as either Chairman or Chief Executive Officer of the Company, he shall have the right (i) to serve as a member of the Board, and (ii) to designate two other individuals as nominees for election to the Board."

By deleting the phrase "six hundred seventy-five thousand ($675,000)" each time it appears in Section 4(a) and replacing it with "seven hundred fifty thousand ($750,000)".

By inserting immediately following Section 5(b) a new Section 5(c) to read as follows:

"(c) Effective as of the Closing Date (as defined in the Agreement and Plan of Merger by and among the Company, Teton Formation L.L.C. and Teton Acquisition Corp. (the "Merger Agreement")) and conditioned on the occurrence of the Closing, the Executive shall be granted under the Company's 1996 Stock Option Plan (or


any successor plan thereto), new options (the "New Options") for a number of shares of Company common stock equal to 30% of the sum of

The Board of Directors, at any time or from time to time may, and is hereby authorized to, further divide the authorized and unissued shares of Preferred Stock into one or more classes or series and in connection with the creation of any class or series to determine, in whole or in part, to the full extent now or hereafter permitted by law, by adopting one or more articles of amendment to the Articles of Incorporation providing for the creation thereof, the designation, preferences, limitations and relative rights of such class or series, which may provide for special, conditional or limited voting rights, or no rights to vote at all, and to issue and dispose of any of such shares and any issued but not outstanding shares for such kind and amount of consideration and to such persons, firms or corporations, as may be determined by the Board of Directors, subject to any provisions of law then applicable.

E. The Board of Directors, at any time or from time to time may, and is hereby authorized to, create and issue, whether or not in connection with the issue and sale of any shares of its Common Stock, Preferred Stock or other securities of the Corporation, warrants, rights and/or options entitling the holders thereof to purchase from the Corporation any shares of its Common Stock, Preferred Stock or other securities of the Corporation. Such warrants, rights, or options shall be evidenced by such instrument or instruments as shall be approved by the Board of Directors. The terms upon which, the time or times (which may be limited or unlimited in duration) at or within which, and the price or prices (which shall be not less than the minimum amount prescribed by law, if any) at which any such shares or other securities may be purchased from the Corporation upon the exercise of any such warrant, right or option shall be fixed and stated in the resolution or resolutions of the Board of Directors providing for the creation and issue of such warrants, rights or options. The Board of Directors is hereby authorized to create and issue any such warrants, rights or options from time to time for such consideration, if any, and to such persons, firms or corporations, as the Board of Directors may determine.

F. The Corporation may authorize the issue of some or all of the shares of any or all of the classes of its capital stock without certificates.

G.

Such scrip certificates upon presentation together with similar scrip certificates representing in the aggregate an interest in one or more full shares of stock of any class shall entitle the holders thereof to receive one or more full shares of stock of such class. Such scrip certificates may contain such terms and conditions as shall be fixed by the Board of Directors and may become void and of no effect after a period to be determined by the Board of Directors and to be specified in such scrip certificates.

H. The Corporation shall be entitled to treat the person in whose name any share of Common Stock or Preferred Stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any person, whether or not the Corporation shall have notice thereof except as may be expressly provided otherwise by the laws of the State of Iowa.

ARTICLE IV.

A. Creation, Designation and Amount of First Series of Preferred Stock. A first series of the Preferred Stock is hereby created as follows: The shares of such series (the "Preferred Shares") shall be designated as "Zero Coupon Convertible Preferred Stock", and the number of shares constituting such Preferred Stock shall be 40,000,000.

B. Dividends and Distributions. In case the Corporation shall at any time or from time to time declare, order, pay or make a dividend or other distribution (including, without limitation, any distribution of stock or other securities or property or rights or warrants to subscribe for securities of the Corporation or any of its subsidiaries by way of a dividend, distribution or spin-off) on its Common Stock, other than (i) a distribution made in compliance with the provisions of Section F of this Article IV or (ii) a dividend or distribution made in Common Stock, the holders of the Preferred Shares shall be entitled (unless such right shall be waived by the affirmative vote or consent of the holders of at least two-thirds of the number of the then outstanding Preferred Shares) to receive from the Corporation with respect to each Preferred Share held, any dividend or distribution that would be received by a holder of the number of shares (including fractional shares) of Common Stock into which such Preferred Share is convertible on the record date for such dividend or distribution, with fractional shares of Common Stock deemed to be entitled to the corresponding fraction of any dividend or distribution that would be received by a whole share. Any such dividend or distribution shall be declared, ordered, paid or made at the same time such dividend or distribution is declared, ordered, paid or made on the Common Stock.

C. Conversion Rights.

Each Preferred Share is convertible at the option of the holder thereof into one Conversion Unit at any time upon the occurrence of a Conversion Event. A Conversion Unit will initially be one share of Common Stock of the Corporation adjusted as follows:

(i) Stock splits, combinations, reclassifications etc. In case the Corporation shall at any time or from time to time declare a dividend or make a distribution on the outstanding shares of Common Stock payable in Common Stock or subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or combine or reclassify the outstanding shares of Common Stock into a smaller number of shares of Common Stock, then, and in each such event, the number of shares of Common Stock into which each Preferred Share is convertible shall be adjusted so that the holder thereof shall be entitled to receive, upon conversion thereof, the number of shares of Common Stock which such holder would have been entitled to receive after the happening of any of the events described above had such share been converted immediately prior to the happening of such event or the record date therefor, whichever is the earlier. Any adjustment made pursuant to this clause (i) shall become effective (I) in the case of any such dividend or distribution on the record date for the determination of holders of shares of Common Stock entitled to receive such dividend or distribution, or

-3-

(II) in the case of any such subdivision, reclassification or combination, on the day upon which such corporate action becomes effective.

(ii) Issuances of Additional Shares below Fair Value Price. In case the Corporation shall issue shares of Common Stock (or rights or warrants or other securities exercisable or convertible into or exchangeable (collectively, a "conversion") for shares of Common Stock) (collectively, "convertible securities") (other than in Permitted Transactions) at a price per share (or having a conversion price per share) less than the Fair Value Price as of the date of issuance of such shares (or of such convertible securities), then, and in each such event, the number of shares of Common Stock into which each Preferred Share is convertible shall be adjusted so that the holder thereof shall be entitled to receive, upon conversion thereof, the number of shares of Common Stock determined by multiplying the number of shares of Common Stock into which such share was convertible immediately prior to such date of issuance by a fraction, (I) the numerator of which is the sum of (1) the number of shares of Common Stock outstanding on such date and (2) the number of additional shares of Common Stock issued (or into which the convertible securities may convert), and (II) the denominator of which is the sum of (1) the number of shares of Common Stock outstanding on such date and (2) the number of shares of Common Stock which the aggregate consideration receivable (including any amounts payable upon conversion of convertible securities) by the Corporation for the total number of additional shares of Common Stock so issued (or into which the convertible securities may convert) would purchase at the Fair Value Price on such date. For purposes of the foregoing, "Permitted Transactions" shall include issuances (i) as consideration for the acquisition of businesses and/or related assets, and (ii) in connection with employee benefit plans and any other transaction approved by the Board of Directors (including the approval of the directors elected by the holders of the Preferred Shares), and "Fair Value Price" shall mean the average of the closing prices on the principal stock exchange or over-the-counter quotation system on which the Common Stock is then listed or quoted, or if not then listed or quoted, the fair value of the Corporation's Common Stock as determined in good faith by the Board of Directors. Although Permitted Transactions do not require adjustment of a Conversion Unit, the issuance of equity and equity-linked securities in a Permitted Transaction remains subject to the vote of the Preferred Shares as provided in Section D of this Article IV. Any adjustment made pursuant to this clause (ii) shall become effective immediately upon the date of such issuance.

(iii) Mergers, Consolidations, Sales of Assets etc. In case the Corporation shall be a party to any transaction (including a merger, consolidation, sale of all or substantially all of the Corporation's assets, liquidation or recapitalization of the Corporation, but excluding any transaction described in clause (i) or
(ii) above) in which the previously outstanding Common Stock shall be changed into or, pursuant to the operation of law or the terms of the transaction to which the Corporation is a party, exchanged for different securities of the Corporation or common stock or other securities or interests in another Person or other property (including cash) or any combination of the foregoing, then, as a condition of the consummation of such transaction, lawful and

-4-

adequate provision shall be made so that each holder of Preferred Shares shall be entitled, upon conversion, to an amount per share equal to (A) the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged times (B) the number of shares of Common Stock into which such share was convertible immediately prior to the consummation of such transaction. Any adjustment made pursuant to this clause (iii) shall become effective immediately upon the consummation of such transaction.

In calculating the adjustments provided in clauses (i), (ii) and (iii) above, a Conversion Unit shall include any fractional share resulting from the calculation.

A "Conversion Event" includes (i) any conversion of Preferred Shares that would not cause the holder of the shares of Common Stock issued upon conversion (or any affiliate of such holder) or the Corporation to become subject to regulation as a registered holding company, or as a subsidiary of a registered holding company, under the Public Utility Holding Company Act of 1935, as amended from time to time and any successor legislation ("PUHCA") either as a result of the repeal or amendment of PUHCA, the number of shares involved or the identity of the holder of such shares and (ii) a Company Sale. A "Company Sale" includes any involuntary or voluntary liquidation, dissolution, recapitalization, winding-up or termination of the Corporation and any merger, consolidation or sale of all or substantially all of the assets of the Corporation.

The holder of any Preferred Shares may exercise such holder's right to convert each such share into a Conversion Unit by surrendering for such purpose to the Corporation, at its principal office or at such other office or agency maintained by the Corporation for that purpose, a certificate or certificates representing the Preferred Shares to be converted accompanied by a written notice stating that such holder elects to convert all or a specified whole number of such shares in accordance with the provisions of this Section C of this Article IV and specifying the name or names in which such holder wishes the certificate or certificates for securities included in the Conversion Unit or Units to be issued. In case such notice shall specify a name or names other than that of such holder, such notice shall be accompanied by payment of all transfer taxes payable upon the issuance of securities included in the Conversion Unit or Units in such name or names. Other than such taxes, the Corporation will pay any and all issue and other taxes (other than taxes based on income) that may be payable in respect of any issue or delivery of the securities and other property then included in a Conversion Unit or Units upon conversion of Preferred Shares pursuant hereto. As promptly as practicable, and in any event within three Business Days after the surrender of such certificate or certificates and the receipt of such notice relating thereto and, if applicable, payment of all transfer taxes (or the demonstration to the satisfaction of the Corporation that such taxes have been paid), the Corporation shall deliver or cause to be delivered (i) certificates representing the number of validly issued, fully paid and nonassessable shares of Common Stock (or other securities included in the Conversion Unit or Units) to which the holder of Preferred Shares so converted shall be entitled and (ii) if less than the full number of Preferred Shares evidenced by the surrendered certificate or certificates are being converted, a new certificate or certificates, of like tenor, for the number of shares evidenced by such surrendered certificate or certificates less the number of shares converted. Such conversion shall be deemed to have been made at the close of business on the date of giving of such notice and such surrender of the certificate or certificates representing the

-5-

Preferred Shares to be converted so that the rights of the holder thereof as to the shares being converted shall cease except for the right to receive the securities and other property included in the Conversion Unit or Units in accordance herewith, and the Person entitled to receive the securities and other property included in the Conversion Unit or Units shall be treated for all purposes as having become the record holder of such securities and other property included in the Conversion Unit or Units at such time. No holder of Preferred Shares shall be prevented from converting Preferred Shares, and any conversion of Preferred Shares in accordance with the terms of this Section C of this Article IV shall be effective upon surrender, whether or not the transfer books of the Corporation for the Common Stock are closed for any purpose.

The Corporation shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Preferred Shares, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all then outstanding Preferred Shares. The Corporation shall from time to time, subject to and in accordance with the Act, increase the authorized amount of Common Stock if at any time the number of authorized shares of Common Stock remaining unissued shall not be sufficient to permit the conversion at such time of all then outstanding Preferred Shares.

Whenever the number of shares of Common Stock and other property comprising a Conversion Unit into which each Preferred Share is convertible is adjusted as provided in this Section C of this Article IV, the Corporation shall promptly mail to the holders of record of the outstanding Preferred Shares at their respective addresses as the same shall appear in the Corporation's stock records a notice stating that the number of shares of Common Stock and other property comprising a Conversion Unit into which each Preferred Share is convertible has been adjusted and setting forth the new number of shares of Common Stock (or describing the new stock, securities, cash or other property) into which each Preferred Share is convertible, as a result of such adjustment, a brief statement of the facts requiring such adjustment and the computation thereof, and when such adjustment became effective.

D. Voting Rights.

The holders of the Preferred Shares shall have the following voting rights:

(A) The holders of the then-outstanding Preferred Shares shall be entitled to elect, as a class, two (out of a total of ten) directors to the Board of Directors and to elect the replacement for any director elected by them who for any reason ceases to serve as a director. In addition, without first obtaining the consent or approval of the holders of a majority of the then-outstanding Preferred Shares, voting as a separate class, the Corporation will not (a) effect any Fundamental Transaction or (b) amend the provisions of the Articles of Incorporation of the Corporation in any manner which would alter or change the powers, preferences or special rights of the Preferred Shares or that would otherwise adversely affect the rights of the holders of the Preferred Shares. A "Fundamental Transaction" includes the following (in each case referring to a single transaction or series of related transactions): (i) the sale, lease, exchange, mortgage or other disposition (including any spin-off or split-up) of any business or assets having a fair

-6-

market value of 25% or more of the fair market value of the business or assets of the Corporation and its subsidiaries taken as a whole, the merger or consolidation of the Corporation with any other Person, a liquidation, dissolution or winding-up of the Corporation or any recapitalization or reclassification of the securities of the Corporation; (ii) the acquisition of any business or assets (by way of merger, acquisition of stock or assets or otherwise) or the making of capital expenditures not included in the applicable annual budget approved by the Board of Directors, in each case for a consideration or involving expenditures in excess of $50,000,000; (iii) the issuance, grant or sale, or the repurchase, of any equity securities (or any equity-linked securities or obligations) of the Corporation (or securities convertible into or exchangeable or exercisable for any such equity securities);
(iv) transactions with officers, directors, stockholders and affiliates of the Corporation except (x) to the extent effectuated on terms no less favorable to the Corporation than those obtainable in an arms' length transaction with an unaffiliated Person or (y) in the case of cash compensation arrangements, which are approved by the Board of Directors (without regard to the directors elected by the holders of the Preferred Shares); (v) the removal as chief executive officer of the Corporation of the person occupying that position on the date of original issuance of the Preferred Shares (the "Initial CEO") and (vi) the appointment or removal of any person as chief executive officer of the Corporation after the removal, resignation, death or disability of the Initial CEO (the consent of the holders of the Preferred Stock as to the matters set forth in this clause (vi) not to be unreasonably withheld).

(B) Except as set forth herein, or as otherwise provided by law, holders of the Preferred Shares shall have no voting rights.

E. Reacquired Shares.

Any Preferred Shares converted, purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock subject to the conditions and restrictions on issuance set forth herein, in the Articles of Incorporation, or in any Articles of Amendment creating a series of Preferred Stock or any similar stock or as otherwise required by law.

F. Liquidation, Dissolution or Winding Up.

Upon any involuntary or voluntary liquidation, dissolution, recapitalization, winding-up or termination of the Corporation, the assets of the Corporation available for distribution to the holders of the Corporation's capital stock shall be distributed in the following priority, with no distribution pursuant to the second priority until the first priority has been fully satisfied and no distribution pursuant to the third priority until the first and second priorities have both been fully satisfied, First, to the holders of the Preferred Shares for each Preferred Share, a liquidation preference of $1.00 per share, Second, to the holders of Common Stock, ratably, an amount equal to (i) $1.00 divided by the number of shares of Common Stock then comprising a Conversion

-7-

Unit, multiplied by (ii) the number of shares of Common Stock then outstanding, and Third, to the holders of the Preferred Shares and the Common Stock (ratably, on the basis of the number of shares of Common Stock then outstanding and, in the case of the Preferred Shares, the number of shares of Common Stock then comprising a Conversion Unit multiplied by the total number of Preferred Shares outstanding), all remaining assets of the Corporation available for distribution to the holders of the Corporation's capital stock.

Neither the consolidation, merger or other business combination of the Corporation with or into any other Person or Persons nor the sale, lease, exchange or conveyance of all or any part of the property, assets or business of the Corporation to a Person or Persons, shall be deemed to be a liquidation, dissolution or winding up of the Corporation for purposes of this Section F of this Article IV.

G. Redemption. The Preferred Shares are not subject to redemption at the option of the Corporation nor subject to any sinking fund or other mandatory right of redemption accruing to the holders thereof.

ARTICLE V.

The term of corporate existence of the Corporation shall be perpetual.

ARTICLE VI.

A. No Person shall own shares of Common Stock equal to or in excess of the Ownership Limit. If there is a purported Transfer or other event caused by any Person or the Corporation such that a Preferred Eligible Shareholder would own shares of Common Stock equal to or in excess of the Ownership Limit, then, that number of shares of Common Stock owned by such Preferred Eligible Shareholder by which the shares of Common Stock owned by such Preferred Eligible Shareholder would be equal to or in excess of the Ownership Limit as a result of the Transfer shall automatically be converted into that same number of shares of Zero Coupon Convertible Preferred Stock. Such conversion shall be effective on the books of the Corporation as of the close of business on the business day prior to the date of the Transfer or other event.

B. If the Board of Directors shall at any time determine in good faith that a Transfer or other event has taken place in violation of this Article VI, the Board of Directors may take such action as it deems advisable to refuse to give effect to or to prevent such Transfer or other event, including, but not limited to, refusing to give effect to such Transfer or other event on the books of the Corporation or instituting proceedings to enjoin such Transfer or other event or transaction; provided, however, that any Transfers or attempted Transfers (or, in the case of events other than a Transfer, ownership) in violation of this Article VI shall be void ab initio in the case of Transfers that would cause ownership of shares of Common Stock equal to or in excess of the Ownership Limit by any Person other than a Preferred Eligible Shareholder, and in the case of ownership or Transfers that would cause ownership of shares of Common Stock equal to or in excess of the Ownership Limit by a Preferred Eligible Shareholder shall automatically result in the conversion described in
Section A of this Article VI, irrespective of any action (or non-action) by the Board of Directors.

-8-

ARTICLE VII

The private property of the shareholders of the Corporation shall be exempt from all corporate debts.

ARTICLE VIII

A. A director of the Corporation shall not be personally liable to the Corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except for liability:

(i) for any breach of the director's duty of loyalty to the Corporation or its shareholders; or

(ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; or

(iii) for any transaction from which the director derives an improper personal benefit; or

(iv) under Section 490.833, or a successor provision, of the Act.

B. If, after the date these Articles of Incorporation are filed with the Iowa Secretary of State, the Act is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be deemed eliminated or limited to the fullest extent permitted by the Act, as so amended. Any repeal or modification of Section A or this Section B of this Article VIII, by the shareholders of the Corporation shall be prospective only and shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

ARTICLE IX

A. Each person who was or is a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative, investigative or arbitration and whether formal or informal ("proceeding"), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director, officer or employee, of the Corporation or is or was serving at the request of the Corporation as a director, officer or employee of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity while serving as a director, officer or employee or in any other capacity while serving as a director, officer or employee, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Act, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification

-9-

rights than the Act permitted the Corporation to provide prior to such amendment), against all reasonable expenses, liability and loss (including without limitation attorneys' fees, all costs, judgments, fines, Employee Retirement Income Security Act excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith. Such right shall be a contract right and shall include the right to be paid by the Corporation expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that the payment of such expenses incurred by a director, officer or employee in his or her capacity as a director, officer or employee (and not in any other capacity in which service was or is rendered by such person while a director, officer or employee including, without limitation, service to an employee benefit plan) in advance of the final disposition of such proceeding, shall be made only upon delivery to the Corporation of (i) a written undertaking, by or on behalf of such director, officer or employee, to repay all amounts so advanced if it should be determined ultimately that such director, officer or employee is not entitled to be indemnified under this Article IX or otherwise, or (ii) a written affirmation by or on behalf of such director, officer or employee that, in such person's good faith belief, such person has met the standards of conduct set forth in the Act.

B. If a claim under Section A is not paid in full by the Corporation within 30 days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expenses of prosecuting such claim. It shall be a defense to any such action that the claimant has not met the standards of conduct which make it permissible under the Act for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. The failure of the Corporation (including its Board of Directors, independent legal counsel or its shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the Act, shall not be a defense to the action or create a presumption that the claimant had not met the applicable standard of conduct.

C. Indemnification provided hereunder shall, in the case of the death of the person entitled to indemnification, inure to the benefit of such person's heirs, executors or other lawful representatives. The invalidity or unenforceability of any provision of this Article IX shall not affect the validity or enforceability of any other provision of this Article IX.

D. Any action taken or omitted to be taken by any director, officer or employee in good faith and in compliance with or pursuant to any order, determination, approval or permission made or given by a commission, board, official or other agency of the United States or of any state or other governmental authority with respect to the property or affairs of the Corporation or any such business corporation, not-for-profit corporation, joint venture, trade association or other entity over which such commission, board, official or agency has jurisdiction or authority or purports to have jurisdiction or authority shall be presumed to be in compliance with the standard of conduct set forth in Section 490.851 (or any successor provision) of the Act whether or not it may thereafter be determined that such order, determination, approval or permission was unauthorized, erroneous, unlawful or otherwise improper.

-10-

E. Unless finally determined, the termination of any litigation, whether by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the action taken or omitted to be taken by the person seeking indemnification did not comply with the standard of conduct set forth in Section 490.851 (or any successor provision) of the Act.

F. The rights conferred on any person by this Article IX shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Articles of Incorporation, Bylaws, agreement, vote of shareholders or disinterested directors or otherwise.

G. The Corporation may maintain insurance, at its expense, to protect itself and any such director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Act.

ARTICLE X

A. As used in these Articles of Incorporation, the following terms shall have the following meanings:

(i) "Affiliate" shall mean any Person or entity, directly or indirectly, controlling, controlled by or under common control with such Person or entity;

(ii) "Business Day" shall mean any day other than a Saturday, Sunday, or a day on which banking institutions in the State of New York or the State of Iowa are authorized or obligated by law or executive order to close;

(iii) "Ownership Limit" shall mean with respect to any Person, ownership of 10% of the issued and outstanding Common Stock if such ownership would cause such Person to become subject to regulation as a registered holding company under PUHCA or the Corporation or any of its subsidiaries to become subject to regulation as a subsidiary of a registered holding company under PUHCA;

(iv) "Person" shall mean any person or entity of any nature whatsoever, specifically including an individual, a firm, a company, a corporation, a partnership, a trust or other entity;

(v) "Preferred Eligible Shareholder" shall mean a holder of Preferred Shares or its Affiliates; and

(vi) "Transfer" shall mean any sale, assignment, pledge, hypothecation, other disposition or encumbrance, whether or not for consideration.

-11-

ARTICLE XI

These Articles of Incorporation may be amended, repealed, changed or modified at any annual meeting of shareholders of the Corporation or at a special meeting being called for that purpose or by written consent, in compliance with the applicable statutes of the State of Iowa.

           employees of MidAmerican Energy Holdings Company and its subsidiaries
           to share in significant increases in the value of the Company
           realized through the efforts of these individuals. It is intended
           that the Plan, by providing this award and deferral opportunity (U.S.
           only), will assist the Company in retaining and attracting
           individuals of exceptional ability and will act as in incentive to
           align their interests with those of the Company.

1.2        EFFECTIVE DATE.  The Plan shall be effective as of March 14, 2000.

ARTICLE II - DEFINITIONS

For the purpose of the Plan, the following terms shall have the meanings indicated, unless the context clearly indicates otherwise:

2.1        BASE SALARY. "Base Salary" means the base salary payable to a
           Participant with respect to employment services performed for the
           Company by the Participant and considered to be "wages" for purposes
           of federal income tax withholding during the calendar year. For
           purposes of the Plan, Base Salary shall be calculated before
           reduction for any amounts deferred by the Participant pursuant to the
           Company's tax qualified plans which may be maintained under Section
           401(k) or Section 125 of the Internal Revenue Code of 1986, as
           amended (the "Code"), or pursuant to the MidAmerican Energy Holdings
           Company Executive Voluntary Deferred Compensation Plan or any other
           non-qualified plan which permits the voluntary deferral of
           compensation. Inclusion of any forms of compensation other than such
           "wages" and deferred "wages" is subject to approval of the Chairman &
           CEO and the President.

2.2        BENEFICIARY. "Beneficiary" means the person, persons or entity as

           authorized committee thereof.

2.6      DISABILITY. "Disability" means a physical or mental condition that

2.7      INCENTIVE ACCOUNT(S). "Incentive Account(s)" means the account or
         accounts maintained on the books of the Company with respect to each
         Incentive Award and used solely to calculate the amount which may be

         account maintained on their behalf.

2.8      INCENTIVE AWARD(S). "Incentive Award(s)" means the award determined and
         allocated under the terms of the Plan. Each Incentive Award shall be

         Participant's Incentive Account in a subsequent year. By way of
         example: The Year 2000 Incentive Award may relate to the performance of
         the Company over the calendar year 2000 (the Award Year), even though
         the Incentive Award will only be determinable in 2001.

2.9      INTEREST. "Interest" means the amount credited to each Participant's
         Incentive Accounts(s) on each Determination Date, which shall be based
         on the Valuation Funds chosen by the Investment Committee as provided

         Such credits to a Participant's Incentive Account may be either

         the Incentive Account in accordance with the provisions of this Plan.

2.10     INVESTMENT COMMITTEE. "Investment Committee" means the Participants of
         the Plan in the current Award Year. The Investment Committee shall

         amount of Interest to be credited or debited to each Incentive Account.

2.11     NET INCOME. "Net Income" means the definition as applied under
         Generally Accepted Accounting Principles. The Chairman & CEO and the

         events, when appropriate.

2.12     NOMINATION COMMITTEE. "Nomination Committee" means a group of
         Participants appointed by the Chairman & CEO and the President each

         Allocations.

2.13     PARTICIPANT. "Participant" means any employee who is eligible, pursuant
         to Article III, below, to participate in this Plan, and who has been so
         notified by the Chairman &

2

         CEO and the President. Such employee shall remain a Participant in this
         Plan for any award that has been made until such time as all benefits
         payable for that specific Award Year have been paid in accordance with
         the provisions hereof. A Participant may have an Incentive Account and
         not be chosen to participate in a subsequent Award Year. In addition, a
         Participant may be designated as an Associate Participant under the
         terms of this Plan, and the rights and benefits attributable to these
         Associate Participants shall be those attributable to Participants
         under this Plan, unless clearly set forth otherwise. An Associate
         Participant may also be referred to as an "Associate" which term shall
         have the same meaning in all respect as Associate Participant.
         Likewise, a Participant may alternatively be referred to as a "Partner"
         which term shall have the same meaning in all respects as Participant.
         The use of the term "Partner" is not intended to, and does not convey
         any additional rights or responsibilities to a Participant.

2.14     PLAN.  "Plan" means this Long-Term Incentive Partnership Plan as
         amended from time to time.

2.15     RETIREMENT. "Retirement" means the termination of employment with the

2.16     VALUATION FUNDS. "Valuation Funds" means one or more of the
         independently established funds or indices that are identified and
         listed in Exhibit A. These Valuation Funds are used solely to calculate
         the Interest that is credited to each Incentive Account(s) in
         accordance with Article V, and does not represent, nor should it be
         interpreted to convey any beneficial interest on the part of the
         Participant in any specific asset or other property of the Company. The
         determination of the increase or decrease in the performance of each
         Valuation Fund shall be made by the Chairman & CEO and the President in
         their reasonable discretion by reference to the performance of such

4.2 ALLOCATION OF AWARDS. The amount of each Incentive Award shall be allocated among the eligible Participants in the following manner:

a) Initial Allocation. The Nomination Committee shall make recommendations to the Chairman & CEO and the President to allocate seventy-five percent (75%) of the value of the Incentive Award for that year. The Chairman & CEO and the President shall either accept these recommendations or make adjustments that may increase, decrease or eliminate any allocation to any individual Participant. Such allocation (and adjustments, if any) shall be made and communicated to the Participants prior to February 15th of the Award Year, except for the initial plan year.

b) Performance Allocation. The Nomination Committee shall make recommendations to the Chairman & CEO and the President as to the allocation of the remaining twenty-five percent (25%) of the Incentive Award for the Award Year among the eligible Participants. The Chairman & CEO and the President shall either accept these recommendations or make adjustments that may increase, decrease or eliminate any such remaining allocation to any individual Participant.

Any award that is not allocated to Participants will be returned to the Company as an offset to Plan expenses.

These criteria may include the achievement of certain safety performance goals, risk management or other goals established by the Chairman and CEO and the President. The determination of whether any applicable goals have been achieved with respect to an Incentive Award shall be determined as of the time that the dollar value of that Incentive Award is determined in Section 4.3 above.

ARTICLE V - INCENTIVE ACCOUNT

5.1 ACCOUNTS. The Company shall maintain a separate bookkeeping account on behalf of each Participant in the Plan for each Incentive Award. The value of any Incentive Awards allocated to each Participant plus any Interest earned thereon shall be added to such Participant's Incentive Account. These Incentive Accounts shall be used solely to calculate the amount payable to each Participant under the Plan and shall not constitute a separate fund of assets.

5.2 TIMING OF CREDITS. The value of a Participant's share of any Incentive Award shall be credited to a Participant's Incentive Account as of the day determined by the Chairman and CEO and the President but in no event shall the date be later than March 1st of the year following the Award Year. Each Incentive Account shall be increased or decreased by the Interest credited on each Determination Date as though the balance of that Incentive Account as of the beginning of the year had been invested in the applicable Valuation Funds chosen by the Investment Committee. Any distributions to a Participant shall reduce the Participant's Incentive Account as of the date of such distribution.

5.3 VESTING OF ACCOUNTS. Each Participant shall be twenty percent (20%) vested in his or her Incentive Account at December 31st of the Award Year and an additional twenty

5

percent (20%) for each subsequent year except that the Participant shall be considered to be one hundred percent (100%) vested in the event of Retirement or in the event of termination of service as a result of a Disability or death. Participants must be employed on December 31st to vest for the year. Vesting will not be prorated if termination occurs during the year except for Retirement, Disability or death.

5.4 STATEMENT OF ACCOUNTS. The Company shall give to each Participant a statement showing the balances in the Participant's Incentive Account no less frequently than on an annual basis.

ARTICLE VI - PLAN BENEFITS

6.1 NORMAL BENEFIT. The balance of each Participant's Incentive Account shall be paid no earlier than four (4) years, eleven (11) months from the beginning of the Award Year and no later than the fifth anniversary of the beginning of the Award Year. Unless modified pursuant to Section 6.3 below, such amount shall be paid in the form of a lump sum.

6.2 EARLY TERMINATION BENEFIT. In the event that a Participant terminates service with the Company prior to the fifth anniversary of an Award Year, the Participant shall receive the vested portion of the Incentive Account(s) as of the most recent Determination Date, payable in a lump sum. The amount shall be paid as soon as practical after the termination of service, but in no event later than thirty (30) days from the date of termination.

6.3 DEFERRED BENEFIT (U.S. ONLY). With respect to any Incentive Account, the Participant may elect, in a manner acceptable to the Company, to defer the receipt of certain benefits due under this Plan by filing an election to do so no later than December 15th after the third anniversary of the beginning of the Award Year relating to the Incentive Account to be deferred:

a) Such election must be accepted by the Administrative Committee of the MidAmerican Energy Holdings Company Executive Voluntary Deferred Compensation Plan.

b) The balance of the Incentive Account as of the fifth anniversary of the Award Year shall be transferred to the MidAmerican Energy Holdings Company Executive Voluntary Deferred Compensation Plan as of that date and shall thereafter be subject to the terms and conditions of that plan;

c) Such an election shall only permit the deferral of benefits payable under Section 6.1 above, and shall not defer the receipt of benefits payable under any other provision of the Plan; and

d) The acceptance of such an election shall completely satisfy and discharge all obligations on the part of the Company to the Participant (and the Participant's Beneficiary) with respect to such Incentive Account, and the Participant's (and

6

Participant's Beneficiary's) rights under the Plan with respect to such Incentive Account shall terminate.

By way of example: A Participant may elect to defer the receipt of his Year 2000 Incentive Account by filing an election to do so prior to December 15, 2003. If such election is in a form acceptable to the Company and the election is accepted by the Administrative Committee of the MidAmerican Energy Holdings Company Executive Voluntary Deferred Compensation Plan, the balance of the vested portion of that plan year Incentive Account as of December 31, 2004 shall be considered to be transferred to the MidAmerican Energy Holdings Company Executive Voluntary Deferred Compensation Plan as of that date, and all obligations with respect to the Year 2000 Incentive Account for that Participant shall be deemed to be satisfied.

6.4 DEATH BENEFIT. In the event of the death of a Participant prior to complete payment of any Incentive Account, the Participant's Beneficiary shall receive the remaining, vested balance of the Incentive Account(s) determined as if the Participant had terminated service as of the date of death. Such amounts shall be paid in a lump sum as soon as practical after the death of the Participant, but in no event later than thirty (30) days from the date of the Participant's death.

6.5 WITHHOLDING AND PAYROLL TAXES. The Company shall withhold from any payments made pursuant to the Plan any taxes required to be withheld from such payments under law.

6.6 PAYMENT TO GUARDIAN. If a Plan benefit is payable to a minor, a person declared incompetent or a person incapable of handling the disposition of the property, the Company may direct payment to the guardian, legal representative or person having the care and custody of such minor, incompetent or person. The Company may require proof of incompetence, incapacity or guardianship, as it may deem appropriate prior to distribution. Such distribution shall completely discharge the Company from all liability with respect to such benefit.

6.7 EFFECT OF PAYMENT. The full payment of the applicable benefit under this Article VI shall completely discharge all obligations on the part of the Company to the Participant (and the Participant's Beneficiary) with respect to the operation of the Plan, and the Participant's (and Participant's Beneficiary's) rights under the Plan shall terminate.

ARTICLE VII - BENEFICIARY DESIGNATION

7.1 BENEFICIARY DESIGNATION. Each Participant shall have the right, at any time, to designate one (1) or more persons or entity as Beneficiary (both primary as well as secondary) to

7

whom benefits under the Plan shall be paid in the event of Participant's death prior to complete distribution of the Participant's Incentive Account balance. Each Beneficiary designation shall be in a written form prescribed by the Company and shall be effective only when filed with the Company during the Participant's lifetime. Designation by a married Participant to anyone other than the Participant's spouse shall not be effective unless the spouse executes a written consent that acknowledges the effect of the designation, or it is established that the consent cannot be obtained because the spouse cannot be located.

7.2 CHANGING BENEFICIARY. Any Beneficiary designation may be changed by an unmarried Participant without the consent of the previously named Beneficiary by the filing of a new Beneficiary designation with the Company. A married Participant's Beneficiary designation may be changed by a Participant with the consent of the Participant's spouse as provided for in Section 7.1 above. The filing of a new designation shall cancel all designations previously filed.

7.3 CHANGE IN MARITAL STATUS. If the Participant's marital status changes after the Participant has designated a Beneficiary, the following shall apply:

a) If the Participant is married at death but was unmarried when the designation was made, the designation shall be void unless the spouse has consented to it in the manner prescribed in Section 7.1 above.

b) If the Participant is unmarried at death but was married when the designation was made:

i) The designation shall be void if the spouse was named as Beneficiary.
ii) The designation shall remain valid if the spouse was not named and a non-spouse Beneficiary was named.

c) If the Participant was married when the designation was made and is married to a different spouse at death, the designation shall be void unless the new spouse has consented to it in the manner prescribed in Section 7.1 above.

7.4 NO BENEFICIARY DESIGNATION. If any Participant fails to designate a Beneficiary in the manner provided above, if the designation is void, or if the Beneficiary designed by a deceased Participant dies before the Participant or before complete distribution of the Participant's benefits, the Participant's Beneficiary shall be the person in the first of the following classes in which there is a survivor:

a) The Participant's surviving spouse;

b) The Participant's children (including step children) in equal shares, except that if any of the children predeceases the Participant but leaves surviving issue, then such issue shall take by right of representation the share the deceased child would have taken if living;

8

c) The Participant's estate.

7.5 EFFECT OF PAYMENT. Payment to the Beneficiary shall completely discharge the Company's obligations under the Plan and the Company may require a release to that effect from the Beneficiary prior to the distribution.

10.1     AMENDMENT. The Board may at any time amend the Plan by written
         instrument, notice of which is given to all Participants and to
         Beneficiary receiving payments, except that no amendment shall reduce

         deferral election as of the date such notice of the amendment is given.

9

10.2     COMPANY'S RIGHT TO TERMINATE. The Board may at any time partially or
         completely terminate the Plan by written instrument, notice of which is
         given to all Participants and to any Beneficiary receiving payments if,
         in its judgment, the tax, accounting or other effects of the
         continuance of the Plan, or potential payments would not be in the best
         interests of the Company provided that no such termination shall reduce
         any vested benefit and the amount accrued in any Incentive Account or

10.3     PARTIAL TERMINATION. The Board may partially terminate the Plan and if

10.4     PAYMENT ON TERMINATION. In the event of a complete or partial
         termination hereunder, the Plan shall cease to operate or as to a
         partial termination, the Plan shall cease only with respect to the part
         terminated and the Company shall distribute each Incentive Account to
         the appropriate Participant or Beneficiary. Payment shall be made as a
         lump sum within thirty (30) days of Plan termination unless deferral
         elections are effective, in which case payments shall be made to a
         Participant's (or Beneficiary's) account in such deferral plan.

                           ARTICLE XI - MISCELLANEOUS

11.1     UNFUNDED PLAN. This plan is unfunded plan maintained primarily to
         provide deferred compensation benefits for a select group of
         "management or highly-compensated employees" within the meaning of
         Sections 201, 301, and 401 of the Employee Retirement Income Security
         Act of 1974, as amended ("ERISA"), and therefore is exempt from the
         provisions of Parts 2, 3 and 4 of Title I of ERISA. Accordingly, the
         Board may terminate the Plan and make no further benefit payments or
         remove certain employees as Participants if it is determined by the
         United States Department of Labor, a court of competent jurisdiction,
         or an opinion of counsel that the Plan constitutes an employee pension
         benefit plan within the meaning of Section 3 (2) of ERISA (as currently
         in effect or hereafter amended) which is not so exempt.

11.2     COMPANY OBLIGATION. The obligation to make benefit payments to any
         Participant under the Plan shall be an obligation solely of the Company

11.3     UNSECURED GENERAL CREDITOR. Notwithstanding any other provision of this
         Plan, Participants and Participants' Beneficiary shall be unsecured
         general creditors, with no secured or preferential rights to any assets
         of the appropriate Company or any other party for payment of benefits
         under the Plan. Any property held by Company for the purpose of
         generating the cash flow for benefit payments shall remain its general,
         unpledged and unrestricted assets. Company's obligation under the Plan
         shall be an unfunded and unsecured promise to pay money in the future.

10

11.4     TRUST FUND. Company shall be responsible for the payment of all
         benefits provided under the Plan. At its discretion, Company may
         establish one (1) or more trusts for the purpose of assisting in the
         payment of such benefits. Although such a trust shall be irrevocable,
         its assets shall be held for payment of all Company's general creditors
         in the event of insolvency. To the extent any benefits provided under
         the Plan are paid from any such trust, Company shall have no further
         obligation to pay them. If not paid from the trust, such benefits shall
         remain the obligation of Company.

11.5     NONASSIGNABILITY. Neither a Participant nor any other person shall have
         any right to commute, sell, assign, transfer, pledge, anticipate,
         mortgage or otherwise encumber, transfer, hypothecate or convey in
         advance of actual receipt the amounts, if any, payable hereunder, or
         any part thereof, which are, and all rights to which are, expressly
         declared to be unassignable and non-transferable except only pursuant
         to the designated Beneficiary in the event of death or Disability or
         pursuant to a legal will or the laws of intestate succession. No part
         of the amounts payable shall, prior to actual payment, be subject to
         seizure or sequestration for the payment of any debts, judgments,
         alimony or separate maintenance owed by a Participant or any other
         person, nor be transferable by operation of law in the event of a
         Participant's or any other person's bankruptcy or insolvency.

11.6     NOT A CONTRACT OF EMPLOYMENT. This Plan shall not constitute a contract
         of employment between Company and the Participant. Nothing in this Plan
         shall give a Participant the right to be retained in the service of the
         Company or to interfere with the right of the Company to discipline or
         discharge a Participant at any time.

11.7     PROTECTIVE PROVISIONS. A Participant will cooperate with Company by
         furnishing any and all information requested by Company, in order to
         facilitate the payment of benefits hereunder.

11.8     GOVERNING LAW. The provisions of this Plan shall be construed and
         interpreted according to the laws of the State of Iowa, except as
         preempted by federal law.

11.9     VALIDITY. If any provision of this Plan shall be held illegal or
         invalid for any reason, said illegality or invalidity shall not affect
         the remaining parts hereof, but the Plan shall be construed and
         enforced as if such illegal and invalid provision had never been
         inserted herein.

11.10    NOTICE. Any notice required or permitted under the Plan shall be
         sufficient if in writing and hand delivered or sent by registered or
         certified mail. Such notice shall be deemed given as of the date of
         delivery or, if delivery is made by mail, as of the date shown on the
         postmark on the receipt for registration or certification. Mailed
         notice to the Chairman & CEO and the President shall be directed to the
         Company's address. Mailed notice to a Participant or Beneficiary shall
         be directed to the individual's last known address in Company's
         records.

11

11.11    SUCCESSORS. The provisions of this Plan shall bind and inure to the
         benefit of Company and its successors and assigns. The term successors
         as used herein shall include any corporate or other business entity
         which shall, whether by merger, consolidation, purchase or otherwise
         acquire all or substantially all of the business and assets of Company,
         and successors of any such corporation or other business entity.

11.12    TAXING AUTHORITY. If a Participant is subject to a taxing authority or
         jurisdiction which would cause an Incentive Account to be recognized
         and taxed as income by that authority or jurisdiction prior to the time
         it would otherwise be payable under the terms of the Plan, then the
         provisions of the Plan, as applied to that Participant, shall be
         modified such that if the Participant is terminated for cause, as
         defined by the Chairman & CEO and the President, prior to the time an
         Incentive Account is payable, the Participant shall be considered zero
         percent (0%) vested in such award and the entire Incentive Account
         shall be forfeited.

3.6 CHANGE IN EMPLOYMENT STATUS.

If the Committee, in its sole

5

discretion, determines that the Participant no longer qualifies as a member of a select group of management or highly compensated employees, as determined in accordance with the Employee Retirement Income Security Act of 1974, as amended, the Committee may, in its sole discretion terminate any Deferral Commitment for that year, prohibit the Participant from making any future Deferral Commitments and/or distribute the Participant's Account Balances in accordance with Article V of this Plan as if the Participant had terminated employment with the Company as of that time.

ARTICLE IV - DEFERRED COMPENSATION ACCOUNT

4.1 ACCOUNTS. The Compensation deferred by a Participant under the Plan, any Discretionary Contributions and Earnings shall be credited to the Participant's Account(s). Separate accounts may be maintained to reflect the different Accounts chosen by the Participant, and the Participant shall designate the portion of each deferral that will be credited to each Account as set forth in Section 3.2(a), above. These Accounts shall be used solely to calculate the amount payable to each Participant under this Plan and shall not constitute a separate fund of assets.

4.2 TIMING OF CREDITS; WITHHOLDING. A Participant's deferred Compensation shall be credited to each Account designated by the Participant on the 15th day of each month or the last business day of each month consistent with normal payroll processing. Bonus Compensation will be credited when it would normally be payable to the participant. Any Discretionary Contributions shall be credited to the appropriate Account(s) as provided by the Committee. Any withholding of taxes or other amounts with respect to deferred Compensation that is required by local, state or federal law shall be withheld from the Participant's corresponding non-deferred portion of the Compensation to the maximum extent possible, and any remaining amount shall reduce the amount credited to the Participant's Account in a manner specified by the Committee.

4.3 VALUATION FUNDS. A Participant shall designate, at a time and in a manner acceptable to the Committee, one or more Valuation Funds for each Account for the sole purpose of determining the amount of Earnings to be credited or debited to such Account. Such election shall designate the portion of each deferral of Compensation made into each Account that shall be allocated among the available Valuation Fund(s), and such election shall apply to each succeeding deferral of Compensation until such time as the Participant shall file a new election with the Committee. Upon notice to the Committee, the Participant may also reallocate the balance in each Valuation Fund among the other available Valuation Funds as of the next succeeding Determination Date, but in no event shall such re-allocation occur more frequently than monthly.

4.4 DISCRETIONARY CONTRIBUTIONS. Company may make Discretionary Contributions to a Participant's Account. Discretionary Contributions shall be credited at such times and in such amounts as recommended by the Committee and approved by the Compensation Committee of the Board, or the Board in its sole discretion shall determine.

6

shall be allocated among the various Accounts in the same proportion as set forth in section 4.1, above.

4.5 DETERMINATION OF ACCOUNTS. Each Participant's Account as of each Determination Date shall consist of the balance of the Account as of the immediately preceding Determination Date, adjusted as follows:

a) New Deferrals. Each Account shall be increased by any deferred Compensation credited since such prior Determination Date in the proportion chosen by the Participant.

b) Discretionary Contributions. Each Account shall be increased by any Discretionary Contributions credited since such prior Determination Date in the same proportion chosen by the Participant with respect to new deferrals as set forth above.

c) Distributions. Each Account shall be reduced by the amount of each benefit payment made from that Account since the prior Determination Date. Distributions shall be deemed to have been made proportionally from each of the Valuation Funds maintained within such Account based on the proportion that such Valuation Fund bears to the sum of all Valuation Funds maintained within such Account for that Participant as of the Determination Date immediately preceding the date of payment.

d) Earnings. Each Account shall be increased or decreased by the Earnings credited to such Account since such Determination Date, as though the balance of that Account as of the beginning of the current month had been invested in the applicable Valuation Funds chosen by the Participant.

4.6 VESTING OF ACCOUNTS. Each Participant shall be one hundred percent (100%) vested at all times in the amount of Compensation elected to be deferred under this Plan and Earnings thereon, except that the Committee may provide that the amount of any Discretionary Contribution and Earnings thereon shall become vested as determined by the Compensation Committee of the Board.

However, if the Participant terminates employment with the Company prior to the date so chosen by the Participant, the Educational Account shall be added to the Retirement Account as of the date of termination of service and shall be paid in accordance with the provisions of Section 5.1, above.

5.4 DEATH BENEFIT. Upon the death of a Participant prior to the commencement of benefits under this Plan from any Account, Company shall pay to the Participant's beneficiary an amount equal to the Account balance in that Account in a manner chosen by the Participant in the most recent Deferral Commitment.

5.5 HARDSHIP DISTRIBUTIONS. Upon a finding that a Participant has suffered a Financial Hardship or Disability, the Committee may, in its sole discretion, amend the existing Deferral Commitment, or make distributions from any or all of the Participant's Accounts. The amount of such distribution shall be limited to the amount reasonably necessary to meet the Participant's needs resulting from the Financial Hardship or Disability, and will not exceed the Participant's Account balances. If payment is made due to Financial Hardship, the Participant's deferrals under this Plan shall cease for the period of the Financial Hardship or Disability and for twelve (12) months thereafter. Any resumption of the Participant's deferrals under the Plan after such twelve (12) month period shall be made only at the election of the Participant in accordance with Article III herein.

5.6 FORM OF PAYMENT. Unless otherwise specified in paragraphs 5.2 or 5.3, the benefits payable from any Account under this Plan shall be paid in the form of benefit as provided below, and specified by the Participant in the Form of Payment Designation.

         effective for the entire account balance unless amended in writing by
         the Participant and delivered to the Committee. If, at the time payment
         of benefits under this Plan become due and payable, the Participant's
         most recent election as to the form of payment was made within one (1)
         year of such payment, then the most recent election made by the
         Participant more than one year period to the time of payment shall be
         used to determine the form of payment. The permitted forms of benefit
         payments are:

         a) A lump sum amount which is equal to the Account balance; and,
         b) Annual installments for a period of up to ten (10) years where the
         annual payment shall be equal to the balance of the Account immediately
         prior to the payment, multiplied by a fraction, the numerator of which
         is one (1) and the denominator of which commences at the number of
         annual payments initially chosen and is reduced by one (1) in each
         succeeding year. Earnings on the unpaid balance shall be based on the
         most recent allocation among the available Valuation Funds chosen by
         the Participant, made in accordance with Section 4.3, above.

5.7      SMALL ACCOUNT. If the total of a Participant's unpaid Account balances
         as of the Participant's Retirement is less than $50,000, the remaining
         unpaid, Accounts(s) may be paid in a lump sum at the discretion of the
         Committee, notwithstanding any election by the Participant to the
         contrary.

5.8      WITHHOLDING; PAYROLL TAXES. Company shall withhold from any payment
         made pursuant to this Plan any taxes required to be withheld from such
         payments under local, state or federal law. A Beneficiary, however, may
         elect not to have withholding of federal income tax pursuant to Section
         3405(a)(2) of the Code, or any successor provision thereto.

5.9      PAYMENT TO GUARDIAN. If a Plan benefit is payable to a minor or a
         person declared incompetent or to a person incapable of handling the
         disposition of the property, the Committee may direct payment to the
         guardian, legal representative or person having the care and custody of
         such minor, incompetent or person. The Committee may require proof of
         incompetency, minority, incapacity or guardianship as it may deem
         appropriate prior to distribution. Such distribution shall completely
         discharge the Committee and Company from all liability with respect to
         such benefit.

5.10     EFFECT OF PAYMENT. The full payment of the applicable benefit under
         this Article V shall completely discharge all obligations on the part
         of the Company to the Participant (and the Participant's Beneficiary)
         with respect to the operation of this Plan, and the Participant's (and
         Participant's Beneficiary's) rights under this Plan shall terminate.

                     ARTICLE VI - BENEFITICIARY DESIGNATION

6.1      BENEFICIARY DESIGNATION. Each Participant shall have the right, at any
         time, to designate one (1) or more persons or entity as Beneficiary
         (both primary as well as secondary) to whom benefits under this Plan
         shall be paid in the event of Participant's death prior to

9

complete distribution of the Participant's Account balance. Each Beneficiary designation shall be in a written form prescribed by the Committee and shall be effective only when filed with the Committee during the Participant's lifetime. Designation by a married Participant to the Participant's spouse of less than a fifty percent (50%) interest in the benefit due shall not be effective unless the spouse executes a written consent that acknowledges the effect of the designation, or it is established that the consent cannot be obtained because the spouse cannot be located.

6.2 CHANGING BENEFICIARY. Any Beneficiary designation may be changed by an unmarried Participant without the consent of the previously named Beneficiary by the filing of a new Beneficiary designation with the Committee. A married Participant's Beneficiary designation may be changed by a Participant with the consent of the Participant's spouse as provided for in Section 6.1 above. The filing of a new designation shall cancel all designations previously filed.

6.3 CHANGE IN MARITAL STATUS. If the Participant's marital status changes after the Participant has designated a Beneficiary, the following shall apply:

a) If the Participant is married at death but was unmarried when the designation was made, the designation shall be void unless the spouse has consented to it in the manner prescribed in Section 6.1 above.
b) If the Participant is unmarried at death but was married when the designation was made:
i) The designation shall be void if the spouse was named as Beneficiary.
ii) The designation shall remain valid if the spouse was not named and a non-spouse Beneficiary was named.
c) If the Participant was married when the designation was made and is married to a different spouse at death, the designation shall be void unless the new spouse has consented to it in the manner prescribed in Section 6.1 above.

6.4 NO BENEFICIARY DESIGNATION. If any Participant fails to designate a Beneficiary in the manner provided above, if the designation is void, or if the Beneficiary designated by a deceased Participant dies before the Participant or before complete distribution of the Participant's benefits, the Participant's Beneficiary shall be the person in the first of the following classes in which there is a survivor:

a) The Participant's surviving spouse;
b) The Participant's children in equal shares, except that if any of the children predeceases the Participant but leaves surviving issue, then such issue shall take by right of representation the share the deceased child would have taken if living;
c) The Participant's estate.

6.5 EFFECT OF PAYMENT. Payment to the Beneficiary shall completely discharge the Company's obligations under this Plan.

9.2 COMPANY'S RIGHT TO TERMINATE. The Board may at any time partially or completely terminate the Plan if, in its judgment, the tax, accounting or other effects of the continuance of the Plan, or potential payments thereunder would not be in the best interests of Company.

ARTICLE X - MISCELANEOUS

10.1     UNFUNDED PLAN. This plan is unfounded plan maintained primarily to
         provide deferred compensation benefits for a select group of
         "management or highly-compensated employees" within the meaning of
         Sections 201, 301, and 401 of the Employee Retirement Income Security
         Act of 1974, as amended ("ERISA"), and therefore is exempt from the
         provisions of Parts 2, 3 and 4 of Title I of ERISA. Accordingly, the
         Board may terminate the Plan and make no further benefit payments or
         remove certain employees as Participants if it is determined by the
         United States Department of Labor, a court of competent jurisdiction,
         or an opinion of counsel that the Plan constitutes an employee pension
         benefit plan within the meaning of Section 3 (2) of ERISA (as currently
         in effect or hereafter amended) which is not so exempt.

10.2     COMPANY OBLIGATION. The obligation to make benefit payments to any
         Participant under the Plan shall be an obligation solely of the
         appropriate Company with respect to the deferred Compensation
         receivable from, and contributions by, that Company and shall not be an
         obligation of any other company, including any other subsidiary,
         affiliate or subsidiary.

10.3     UNSECURED GENERAL CREDITOR. Notwithstanding any other provision of this
         Plan, Participants and Participants' Beneficiary shall be unsecured
         general creditors, with no secured or preferential rights to any assets
         of the appropriate Company or any other party for payment of benefits
         under this Plan. Any property held by Company for the purpose of
         generating the cash flow for benefit payments shall remain its general,
         unpledged and unrestricted assets. Company's obligation under the Plan
         shall be an unfounded and unsecured promise to pay money in the future.

10.4     TRUST FUND. Company shall be responsible for the payment of all
         benefits provided under the Plan. At its discretion, Company may
         establish one (1) or more trusts, with such trustees as the Board may
         approve, for the purpose of assisting in the payment of such benefits.
         Although such a trust shall be irrevocable, its assets shall be held
         for payment of all Company's general creditors in the event of
         insolvency. To the extent any benefits provided under the Plan are paid
         from any such trust, Company shall have no further obligation to pay
         them. If not paid from the trust, such benefits shall remain the
         obligation of Company.

10.5     NONASSIGNABILITY. Neither a Participant nor any other person shall have
         any right to commute, sell, assign, transfer, pledge, anticipate,
         mortgage or otherwise encumber, transfer, hypothecate or convey in
         advance of actual receipt the amounts, if any, payable hereunder, or
         any part thereof, which are, and all rights

13

         to which are, expressly declared to be unassignable and
         non-transferable. No part of the amounts payable shall, prior to actual
         payment, be subject to seizure or sequestration for the payment of any
         debts, judgments, alimony or separate maintenance owed by a Participant
         or any other person, nor be transferable by operation of law in the
         event of a Participant's or any other person's bankruptcy or
         insolvency.

10.6     NOT A CONTRACT OF EMPLOYMENT. This Plan shall not constitute a contract
         of employment between Company and the Participant. Nothing in this Plan
         shall give a Participant the right to be retained in the service of
         Company or to interfere with the right of the Company to discipline or
         discharge a Participant at any time.

10.7     PROTECTIVE PROVISIONS. A Participant will cooperate with Company by
         furnishing any and all information requested by Company, in order to
         facilitate the payment of benefits hereunder, and by taking such
         physical examinations as Company may deem necessary and taking such
         other action as may be requested by Company.

10.8     GOVERNING LAW. The provisions of this Plan shall be construed and
         interpreted according to the laws of the State of Iowa, except as
         preempted by federal law.

10.9     VALIDITY. If any provision of this Plan shall be held illegal or
         invalid for any reason, said illegality or invalidity shall not affect
         the remaining parts hereof, but this Plan shall be construed and
         enforced as if such illegal and invalid provision had never been
         inserted herein.

10.10    NOTICE. Any notice required or permitted under the Plan shall be
         sufficient if in writing and hand delivered or sent by registered or
         certified mail. Such notice shall be deemed given as of the date of
         delivery or, if delivery is made by mail, as of the date shown on the
         postmark on the receipt for registration or certification. Mailed
         notice to the Committee shall be directed to the company's address.
         Mailed notice to a Participant or Beneficiary shall be directed to the
         individual's last known address in Company's records.

10.11    SUCCESSORS. The provisions of this Plan shall bind and inure to the
         benefit of Company and its successors and assigns. The term successors
         as used herein shall include any corporate or other business entity
         which shall, whether by merger, consolidation, purchase or otherwise

Section 7.1. Establishment of a Rabbi Trust. After the Effective Date, the Company shall be authorized, but shall not be required, to establish a revocable Rabbi Trust for the benefit of the Participants, both active and retired. Any such Rabbi Trust shall have an independent trustee, selected by the Company, and, it shall contain restrictions on the Company's ability to amend or terminate any of the terms thereof after the Rabbi Trust shall become irrevocable as provided in Section 7.2.

All assets held in the Rabbi Trust (while revocable or irrevocable) shall at all times be specifically subject to the claims of the Company's general creditors in the event of bankruptcy or insolvency; such terms shall be specifically defined within the provisions of the Rabbi Trust, along with a required procedure for notifying the Trustee of any such bankruptcy or insolvency.

Section 7.2. Causing the Trust to Become Irrevocable. The instrument establishing any such Rabbi Trust shall provide that the Rabbi Trust shall be revocable until the occurrence of either of the following:

(i) A Change in Control; or

(ii) A majority vote by the Incumbent Board to make the Rabbi Trust irrevocable.

Section 7.3. Payment of Benefits from the Trust. The Company shall be primarily obligated to pay all benefits of Participants under the Plan, whether the Rabbi Trust is revocable or irrevocable at the time. In the event the

-10-

Company fails to fulfill any such obligation hereunder in a timely manner, the Trustee shall be empowered, under the terms of the Rabbi Trust, to either cash in any related life insurance policies or to borrow against the policies, to the extent necessary to pay past due benefits directly from the Trust.

VIII. BENEFICIARY DESIGNATION

Section 8.1. Designation of Beneficiary. Each Participant shall be entitled to designate one or more beneficiaries by filing a signed, written notice of such designation with the Committee, in a form as the Committee may prescribe. A Participant may revoke or modify a beneficiary designation at any time by filing a new beneficiary designation form with the Committee.

Section 8.2. Payment to a Participant's Estate. A Participant's beneficiary designation shall be deemed automatically revoked in the event all designated beneficiaries predecease such Participant or, if the sole beneficiary is such Participant's Spouse, in the event of dissolution of marriage.

IX. MISCELLANEOUS

Section 9.1. Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily to provide benefits to a "select group of management or highly compensated employees" within the meaning of Sections 201, 301, and 401 of ERISA and, therefore, is further intended to be exempt from the provisions of Parts 2, 3, and 4 of Title I of ERISA. Accordingly, the Committee may terminate the Plan for any or all Participants in order to achieve and maintain this intended result, provided that previously accrued benefits hereunder shall not be reduced or otherwise adversely affected without the written consent of the affected Participants.

Section 9.2. Withholding. The Company shall have the right to require Participants to remit to the Company an amount sufficient to satisfy Federal, state, and local tax withholding requirements, or to deduct from any or all payments made pursuant to the Plan amounts sufficient to satisfy such tax withholding requirements. In the event any FICA, FUTA, Social Security, Medicare or any similar taxes become due on benefits (or the value of such benefits) accrued under this Plan at any time prior to the actual payment of benefits under this Plan, the Company shall be authorized to withhold from the regular salary of such Participant the amount of any such tax payable by the

-11-

Participant. Withholding shall take place during the same calendar year in which the taxes on such benefits become due, or at such time as may be required by Internal Revenue Service regulations.

Section 9.3. Costs of the Plan. All costs of implementing and administering the Plan shall be borne by the Company.

Section 9.4. Nontransferability. Neither the Participants nor any designated beneficiary shall have the right to sell, assign, transfer, or otherwise convey the right to receive any payment hereunder; nor shall any such payment be subject to attachment, garnishment, levy, pledge, bankruptcy, or any other manner or kind of execution in connection with any claim against the Participants or any designated beneficiary thereof.

Section 9.5. Successors. All obligations of the Company under the Plan shall be binding upon and inure to the benefit of any successor to the Company, whether the existence of such successor is the direct or indirect result of a merger, consolidation, or reorganization involving the Company or the purchase or other acquisition of all or substantially all of the business and/or assets of the Company.

Section 9.6. Address of Participant or Beneficiary. Each Participant shall keep the Company apprised of his or her current address and that of any designated beneficiary during his or her participation in the Plan. Upon the death of a Participant, any beneficiaries entitled to receive benefit payment under the Plan shall keep the Company apprised of their current address until the entire amount to be distributed has been paid.

Section 9.7. Applicable Law. To the extent not preempted by Federal law, the Plan shall be governed by and construed in accordance with the laws of the state of Iowa.

                 Assumed Yorkshire Debt and the Assumed Yorkshire Swaps) are,
                 prior to Completion, reduced to below(pound)10 million (without
                 any other liability on the part of any Sale Companies in
                 respect of such Borrowings other than in relation to the
                 retained Borrowings) and all of the Non-Retained Inter-Company

        all Non-Assumed Yorkshire Swaps, if after Completion Northern
        becomes aware that there were any Non-Assumed Yorkshire Swaps

        becoming aware of such Swaps to close out and settle such
        Non-Assumed Yorkshire Swaps and, if such Non-Assumed Yorkshire
        Swaps are so closed-out and settled with any payment due to any
        Sale Company, Northern shall account to Innogy for such monies
        and if the close-out and settlement results in any Sale Company
        making a payment to any third party which results in the Sale

        third party, Innogy shall forthwith on demand indemnify the

        Northern, pay such amounts directly to Northern or as Northern
        may direct.

        the ordinary course of business and the Yorkshire Hiveout
        Agreement and agreements entered into pursuant to the Yorkshire

         6.6.1      to effect Completion so far as practicable having regard to
                    the defaults which have occurred; or

                    unable to comply with the foregoing provisions of this

         6.7.1      As soon as reasonably practicable after the date of this
                    Agreement, Innogy shall procure that (if one has not already
                    been made) an application shall be made to H.M. Customs &
                    Excise pursuant to Section 43B of the VATA 1994 for the
                    exclusion of each Sale Company from the bodies treated as
                    members of the same VAT group as Innogy for the purposes of
                    Section 43 of the VATA 1994 (the VENDOR VAT GROUP) and for
                    such exclusion to take effect on Completion or, if H.M.
                    Customs & Excise do not permit this, at the earliest date
                    following Completion permitted by Section 43B.

         6.7.2      Pending the taking effect of such application and for so
                    long thereafter as may be necessary, each of Innogy and
                    Northern shall procure that such information (if applicable)
                    is provided to the other as may be required to enable the
                    continuing representative member of the Vendor VAT Group to
                    make all the returns required of it in respect of the Vendor
                    VAT Group.

         6.7.3      When the exclusion takes effect after Completion, Innogy and
                    Northern shall procure that such payments shall be made
                    between such representative member and the Sale Companies as
                    may be appropriate to ensure that the resulting position as
                    between such companies is as close as possible to the
                    position which would have obtained if such application or
                    applications had taken effect on the date of Completion.

                            Disclosure Letter and any matter provided for under
                            the terms of this Agreement; and

                    (ii)    any matter or thing hereafter done or omitted to be
                            done pursuant to this Agreement or otherwise at the
                            request in writing or with the approval in writing
                            of the Purchaser.

         7.1.2      Save as expressly otherwise provided, the Warranties shall
                    be separate and independent and shall not be limited by
                    reference to any other paragraph of the said Schedule or by
                    anything in this Agreement or the Tax Deed of Covenant.

         7.1.3      The only Warranties given in respect of the Properties are
                    those set out in paragraph 2.5 of Part A of Schedule 2 and

7.2 Limitation of Liability

The provisions of Schedule 6 shall apply.

7.3 Effect of Completion

The Warranties and all other provisions of this Agreement and the Tax Deed of Covenant insofar as the same shall not have been performed at Completion shall not be extinguished or affected by Completion, or by any other event or matter whatsoever (including any satisfaction and/or waiver of any condition contained in Clause 4.1), except by a specific and duly authorised written waiver or release by the Purchaser.

7.4 Right of Termination

24

If prior to Completion, any event (or events) shall occur which would result in any of the Northern Warranties (in the case of Northern) or the Innogy Warranties (in the case of Innogy) being untrue or misleading as if they had been given again at Completion which individually (or in aggregate) results in or is reasonably likely to result in a deterioration of 20 percent of the enterprise value of the Northern Sale Business or the Sale Companies in each case as a whole compared with the enterprise value of such Business or Companies (as the case may be) as a whole as at the date of this Agreement (such deterioration being a deterioration of (pound)94,400,000 in the case of the Northern Sale Business and of (pound)200,800,000 in the case of the Sale Companies), ignoring for this purpose any event (or events) affecting or likely to affect generally all persons carrying on similar businesses in the United Kingdom, then Northern (in the event such deterioration occurs in relation to the Sale Companies) and the Innogy Guarantor (in the event such deterioration occurs in relation to the Northern Sale Business) shall be entitled by notice in writing to the Innogy Guarantor or Northern respectively to terminate this Agreement; but the occurrence of such an event (or events) shall not give rise to any right to damages or compensation.

If Northern and the Innogy Guarantor are unable to agree within 5 Business Days from the date of service of written notice by Northern or the Innogy Guarantor (as the case may be) in accordance with this Clause 7.4 that such event or events has resulted in or would be reasonably likely to result in a deterioration of 20 per cent of the enterprise value (as described above), either Northern or Innogy may call for an independent expert, jointly appointed by the parties (the "EXPERT"), to determine whether such a deterioration has occurred or would be reasonably likely to occur and the Expert shall make such determination (but shall not address whether such deterioration arose as a result of a breach of warranty) within 10 Business Days from the date of the referral to him. If Northern and the Innogy Guarantor are unable to agree upon the Expert within 5 business days from the date either Northern or the Innogy Guarantor calls for an independent expert, then the Expert shall be appointed by the President for the time being of the Institute of Chartered Accountants in England and Wales on the application of either Northern or the Innogy Guarantor. The Expert shall act as an expert and not as an arbitrator and his decision shall (in the absence of manifest error) be final and binding on the parties. The fees and expenses of the Expert shall be borne by Northern and the Innogy Guarantor in equal shares unless the Expert otherwise determines.

7.5 Waiver

Save in the case of fraud, Innogy undertakes to Northern not to make or pursue any claim against any Sale Company or its respective officers, employees or agents in connection with assisting Innogy in giving the Warranties, preparing the Disclosure Letter and/or entering into this Agreement and the documents entered into pursuant to this Agreement.

           other party nor any of their agents, officers or employees
           have given), any warranties, representations, indemnities,
           undertakings or other statements whatsoever (written or
           oral) not incorporated into this Agreement or the Tax Deed
           of Covenant or any agreement expressly contemplated by this
           Agreement.

7.7.3      Each party to this Agreement confirms that it has received
           independent legal advice relating to all the matters
           provided for in this Agreement, including the provisions of
           this Clause, and agrees, having considered the terms of this
           Clause and the Agreement as a whole, that the provisions of
           this Clause are fair and reasonable.

           Disclosure Letter and all documents entered into pursuant to
           this Agreement by Northern and/or Innogy and/or the Innogy

         Northern and, pending such release, Northern shall indemnify Innogy or
         the member of the Innogy Group against all liabilities under those
         guarantees and indemnities provided that Northern shall have no

         granting of time for such performance.

         this Agreement and so that the same benefits shall be conferred on
         Northern as it would have received if the Innogy Guaranteed Obligations
         had been duly performed and satisfied by Innogy (as the case may be).

12.3     Continuing Guarantee

         The guarantee in Clause 12.1 is to be a continuing guarantee and
         accordingly is to remain in force until all the Innogy Guaranteed
         Obligations shall have been performed or satisfied. This guarantee is
         in addition to and without prejudice to and not in substitution for any
         rights or security which Northern may now or hereafter have or hold for
         the performance and observance of the Innogy Guaranteed Obligations.

12.4     Legal limitations etc.

         recoverable from Innogy by reason of any legal limitation, disability
         or incapacity on or of Innogy or any other fact or circumstance (other
         than any limitation imposed by this Agreement) shall nevertheless be
         enforceable against and recoverable from the Innogy Guarantor.

12.5     Warranties

         The Innogy Guarantor warrants and represents to Northern in the terms
         set out in Part B of Schedule 2.

         NE plc hereby guarantees to Innogy the due and punctual performance and
         observance by Northern of all its obligations, commitments,
         undertakings and warranties under or pursuant to this Agreement (the NE
         PLC GUARANTEED OBLIGATIONS). The liability of NE plc under this Clause
         shall not be released or diminished by any variation of the terms of
         the NE plc Guaranteed Obligations, or any forbearance, neglect or delay
         in seeking performance of the NE plc Guaranteed Obligations or any
         granting of time for such performance.

12.7     Vendor's Default

         If and whenever Northern defaults in the performance of any of the NE
         plc Guaranteed Obligations NE plc shall forthwith upon demand
         unconditionally perform (or procure performance of) and satisfy (or
         procure the satisfaction of) the NE plc Guaranteed Obligations in
         regard to which such default has been made in the manner prescribed by
         this Agreement and so that the same benefits shall be conferred on
         Innogy as it would have received if the NE plc Guaranteed Obligations
         had been duly performed and satisfied by NE plc (as the case may be).

12.8     Continuing Guarantee

         The guarantee in Clause 12.6 is to be a continuing guarantee and
         accordingly is to remain in force until all NE plc Guaranteed
         Obligations shall have been performed or satisfied. This guarantee is
         in addition to an without prejudice to and not in substitution for any
         rights or

29

         security which Innogy may now or hereafter have or hold for the
         performance and observance of the NE plc Guaranteed Obligations.

12.9     Legal limitations etc.

         As a separate and independent stipulation NE plc agrees that any of the
         NE plc Guaranteed Obligations (including, any moneys payable) which may
         not be enforceable against or recoverable from Northern by reason of
         any legal limitation, disability or incapacity on or of NE plc or any
         other fact or circumstance (other than any limitation imposed by this
         Agreement) shall nevertheless be enforceable against and recoverable
         from the Innogy Guarantor.

12.10    Warranties

         NE plc warrants and represents to Innogy in the terms set out in Part C
         of Schedule 2.

         13.4.1     Subject to Clause 13.4.2 this Agreement is personal to the
                    parties to it. Accordingly, no party may, without the prior

                    any of the other's obligations under this Agreement, or any
                    benefit arising under or out of this Agreement.

31

         this Agreement.

13.6     Further Assurance

         At any time after the date of this Agreement either party shall and

         party shall at the cost of the other party execute such documents and
         do such acts and things as the other party may reasonably require for
         the purpose of giving to the other party the full benefit of all the
         provisions of this Agreement.

         Any time, date or period referred to in any provision of this Agreement
         may be extended by mutual agreement between the parties but any time,

13.9     Costs

         Each party shall bear all legal, accountancy and other costs and
         expenses incurred by it in connection with this Agreement and all
         agreements and transactions contemplated by this Agreement (and, in the
         case of Innogy, by any of the Sale Companies prior to Completion in
         relation to the Hiveout Agreement).

13.10    Interest

         If any party defaults in the payment when due of any sum payable under
         this Agreement (whether determined by agreement or pursuant to an order
         of a court or otherwise) the liability of such party (as the case may
         be) shall be increased to include a payment of interest on such sum
         (subject to deduction or withholding of Taxation as appropriate) from
         the date when such payment is due until the date of actual payment (as
         well after as before judgement) at a rate per annum of two per cent
         above the base rate from time to time of National Westminster Bank PLC.
         Such interest shall accrue from day to day.

13.11    Withholdings and Deductions

         13.11.1    All sums payable under this Agreement shall be paid free and
                    clear of all deductions or withholdings whatsoever save only
                    as provided in this Agreement or as may be required by law
                    and without abatement or set-off (whether equitable or
                    otherwise) save only as provided in this Agreement. If any
                    deductions or withholdings are required by law the party
                    making the payment shall (except in the case of payments of
                    interest) be obliged to pay the other party such sums as
                    will, after such deduction or withholding has been made,
                    leave the other party with the same amounts as it

32

                    would have been entitled to receive in the absence of any
                    such requirement to make a deduction or withholding provided
                    that, if either party shall have assigned the benefit in
                    whole or in part of this Agreement in accordance with the
                    provisions of Clause 13.4, the liability of the other party
                    under this Clause 13.11.1 shall be limited to that (if any)
                    which it would have been had no such assignment taken place.

         13.11.2    If the party receiving the payment under this Agreement
                    receives a credit for or refund of any Taxation or other
                    monies payable by it or similar benefit by reason of any
                    deduction or withholding for or on account of Taxation or
                    any other matter then it shall reimburse to the other party
                    such part of such additional payments paid to it pursuant to
                    Clause 13.11.1 above as the party receiving the payment
                    certifies to the other party will leave it (after such
                    reimbursement) in no better or worse position than it would
                    have been if the other party had not been required to make
                    such deduction or withholding.

         part shall to that extent be deemed not to form part of this Agreement
         but the legality, validity or enforceability of any other term or
         provision of this Agreement (including under the law of any other
         jurisdiction) shall not in any way be affected or impaired thereby.

PART II: CERTIFICATION
Certification Instructions: You must cross out item 2 below if you have been notified by
the Internal Revenue Service (the "IRS") that you are currently subject to backup
withholding because of underreporting interest or dividends on your tax return. However, if
after being notified by the IRS that you were subject to backup withholding you received
another notification from the IRS that you are no longer subject to backup withholding, do
not cross out item 2.

Under penalties of perjury, I certify that:
1. The number shown on this form is my correct TIN or a TIN has not been issued to me and
   either (a) I have mailed or delivered an application to receive a TIN to the appropriate
   IRS Center or Social Security Administration Office, or (b) I intend to mail or deliver
   an application in the near future. I understand that if I do not provide my TIN to the
   payor, a portion of all reportable payments made to me by the payor will be withheld
   until I provide my TIN to the payor and that, if I do not provide my TIN to the payor
   within 60 days of submitting this Substitute Form W-9, such retained amounts shall be
   remitted to the IRS as backup withholding.

2. I am not subject to backup withholding because: (a) I am exempt from backup withholding,
   (b) I have not been notified by the IRS that I am subject to backup withholding as a
   result of a failure to report all interest or dividends or (c) the IRS has notified me
   that I am no longer subject to backup withholding.

3. I am a U.S. person (including a U.S. resident alien).

INSTRUCTIONS

FORMING PART OF THE TERMS AND
CONDITIONS OF THE EXCHANGE OFFER

1. DELIVERY OF THIS LETTER AND CERTIFICATES. Certificates for Original Notes or a Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed copy of this Letter and any other documents required by this Letter, must be received by the Exchange Agent at one of its addresses set forth herein on or before the expiration of the exchange offer on the Expiration Date. The method of delivery of this Letter, certificates for Original Notes or a Book-Entry Confirmation, as the case may be, and any other required documents is at the election and risk of the tendering holder, but except as otherwise provided below, the delivery will be deemed made when actually received by the Exchange Agent. If delivery is by mail, the use of registered mail with return receipt requested, properly insured, is suggested.

Holders whose Original Notes are not immediately available or who cannot deliver their Original Notes or a Book-Entry Confirmation, as the case may be, and all other required documents to the Exchange Agent on or before the Expiration Date may tender their Original Notes pursuant to the guaranteed delivery procedures set forth in the Prospectus. Pursuant to such procedure: (i) tender must be made by or through an Eligible Institution (as defined in the Prospectus under the caption "The Exchange Offer - How to Tender"); (ii) prior to the expiration of the exchange offer on the Expiration Date, the Exchange Agent must have received from the Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery (by telegram, telex, facsimile transmission, mail or hand delivery) (x) setting forth the name and address of the holder, the description of the Original Notes and the principal amount of Original Notes tendered, (y) stating that the tender is being made thereby and
(z) guaranteeing that, within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, this Letter together with the certificates representing the Original Notes or a Book-Entry Confirmation, as the case may be, and any other documents required by this Letter will be deposited by the Eligible Institution with the Exchange Agent; and (iii) the certificates for all tendered Original Notes or a Book-Entry Confirmation, as the case may be, as well as all other documents required by this Letter, must be received by the Exchange Agent within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in the Prospectus under the caption "The Exchange Offer - How to Tender."

All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of tendered Original Notes will be determined by the Company, whose determination will be final and binding. The Company reserves the absolute right to reject any or all tenders that are not in proper form or the acceptance of which, in the opinion of the Company's counsel, would be unlawful. The Company also reserves the right to waive any irregularities or conditions of tender as to particular Original Notes. All tendering holders, by execution of this Letter, waive any right to receive notice of acceptance of their Original Notes.

Neither the Company, the Exchange Agent nor any other person shall be obligated to give notice of defects or irregularities in any tender, nor shall any of them incur any liability for failure to give any such notice.

2. PARTIAL TENDERS; WITHDRAWALS. If less than the entire principal amount of any Original Note evidenced by a submitted certificate or by a Book-Entry Confirmation is tendered, the tendering holder must fill in the principal amount tendered in the fourth column of Box 1 above. All of the Original Notes represented by a certificate or by a Book-Entry Confirmation delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated. A certificate for Original Notes not tendered will be sent to the holder, unless otherwise provided in Box 5, as soon as practicable after the Expiration Date, in the event that less than the entire principal amount of Original Notes represented by a submitted certificate is tendered (or, in the case of Original Notes tendered by book-entry transfer, such non-exchanged Original Notes will be credited to an account maintained by the holder with the Book-Entry Transfer Facility).

If not yet accepted, a tender pursuant to the Exchange Offer may be withdrawn prior to the Expiration Date. To be effective with respect to the tender of Original Notes, a notice of withdrawal must: (i) be received by the Exchange Agent before the Company notifies the Exchange Agent that it has accepted the tender of Original Notes pursuant to the Exchange Offer; (ii) specify the name of the person who tendered the Original Notes; (iii) contain a description of the Original Notes to be withdrawn, the certificate numbers shown on the particular

-8-

certificates evidencing such Original Notes and the principal amount of Original Notes represented by such certificates; and (iv) be signed by the holder in the same manner as the original signature on this Letter (including any required signature guarantee).

3. SIGNATURES ON THIS LETTER; ASSIGNMENTS; GUARANTEE OF SIGNATURES. If this Letter is signed by the holder(s) of Original Notes tendered hereby, the signature must correspond with the name(s) as written on the face of the certificate(s) for such Original Notes, without alteration, enlargement or any change whatsoever.

If any of the Original Notes tendered hereby are owned by two or more joint owners, all owners must sign this Letter. If any tendered Original Notes are held in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are names in which certificates are held.

If this Letter is signed by the holder of record and (i) the entire principal amount of the holder's Original Notes are tendered; and/or (ii) untendered Original Notes, if any, are to be issued to the holder of record, then the holder of record need not endorse any certificates for tendered Original Notes, nor provide a separate bond power. If any other case, the holder of record must transmit a separate bond power with this Letter.

If this Letter or any certificate or assignment is signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and proper evidence satisfactory to the Company of their authority to so act must be submitted, unless waived by the Company.

Signatures on this Letter must be guaranteed by an Eligible Institution, unless Original Notes are tendered: (i) by a holder who has not completed the Box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on this Letter; or (ii) for the account of an Eligible Institution. In the event that the signatures in this Letter or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantees must be by an eligible guarantor institution which is a member of The Securities Transfer Agents Medallion Program (STAMP), The New York Stock Exchanges Medallion Signature Program (MSP) or The Stock Exchanges Medallion Program (SEMP) (collectively, "Eligible Institutions"). If Original Notes are registered in the name of a person other than the signer of this Letter, the Original Notes surrendered for exchange must be endorsed by, or be accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by the Company, in its sole discretion, duly executed by the registered holder with the signature thereon guaranteed by an Eligible Institution.

4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders should indicate, in Box 4 or 5, as applicable, the name and address to which the Exchange Notes or certificates for Original Notes not exchanged are to be issued or sent, if different from the name and address of the person signing this Letter. In the case of issuance in a different name, the tax identification number of the person named must also be indicated. Holders tendering Original Notes by book-entry transfer may request that Original Notes not exchanged be credited to such account maintained at the Book-Entry Transfer Facility as such holder may designate.

5. TAX IDENTIFICATION NUMBER. U.S.federal income tax law requires that a holder (other than a person exempt from this requirement as discussed below) whose tendered Original Notes are accepted for exchange must provide the Exchange Agent (as payor) with his or her correct taxpayer identification number ("TIN"), which, in the case of a holder who is an individual, is his or her social security number. If the Exchange Agent is not provided with the correct TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery to the holder of the Exchange Notes pursuant to the Exchange Offer may be subject to back-up withholding. (If withholding results in overpayment of taxes, a refund may be obtained.) Exempt holders (including, among others, all corporations and certain foreign individuals) are not subject to these back-up withholding and reporting requirements.

Under U.S. federal income tax laws, payments made by the Company on account of Exchange Notes issued pursuant to the Exchange Offer may be subject to back-up withholding. In order to prevent back-up withholding, each tendering holder must provide his or her correct TIN by completing the "Substitute Form W-9" in Box 3 certifying that the TIN provided is correct (or that the holder is awaiting a TIN) and that: (i) the holder has not been

-9-

notified by the Internal Revenue Service that he or she is subject to back-up withholding as a result of failure to report all interest or dividends; or (ii) the Internal Revenue Service has notified the holder that he or she is no longer subject to back-up withholding; or (iii) certify in accordance with the "Substitute Form W-9" that such holder is exempt from back-up withholding. Exempt Holders (including, among others, all corporations and certain foreign individuals) are not subject to these back-up withholding and reporting requirements. To prevent possible erroneous back-up withholding, an exempt Holder must check the appropriate box under "Payee Information," enter its correct TIN in Part I of the Substitute Form W-9, and sign and date the form. See the Substitute Form W-9 in Box 3 for additional instructions.

In order for a nonresident alien or foreign entity to qualify as exempt, such person must submit a completed Form W-8BEN, "Certificate of Foreign Status," signed under penalties of perjury attesting to such exempt status. Such forms may be obtained from the Exchange Agent, as payor.

If you do not have a TIN, check the box "Applied For" in Part I of the Substitute Form W-9, consult Part II of the Substitute Form W-9 for instructions on applying for a TIN, and sign and date the form. If you do not provide your TIN to the payor within 60 days, back-up withholding will begin and continue until you furnish your TIN to the payor. Note: Checking the "Applied For" box in Part I of the Substitute Form W-9 indicates that you have already applied for a TIN or that you intend to apply for one in the near future.

If you have any questions concerning the Substitute Form W-9 or any information required therein, please contact the Exchange Agent, as payor.

6. TRANSFER TAXES. The Company will pay all transfer taxes, if any, applicable to the transfer of Original Notes to it or its order pursuant to the Exchange Offer. If, however, the Exchange Notes or certificates for Original Notes not exchanged are to be delivered to, or are to be issued in the name of, any person other than the record holder, or if tendered certificates are recorded in the name of any person other than the person signing this Letter, or if a transfer tax is imposed by any reason other than the transfer of Original Notes to the Company or its order pursuant to the Exchange Offer, then the amount of such transfer taxes (whether imposed on the record holder or any other person) will be payable by the tendering holder. If satisfactory evidence of payment of taxes or exemption from taxes is not submitted with this Letter, the amount of transfer taxes will be billed directly to the tendering holder.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificates listed in this Letter.

7. WAIVER OF CONDITIONS. The Company reserves the absolute right to amend or waive any of the specified conditions in the Exchange Offer in the case of any Original Notes tendered.

8. MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES. Any holder whose certificates for Original Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above, for further instructions.

9. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to the procedure for tendering, as well as requests for additional copies of the Prospectus or this Letter, may be directed to the Exchange Agent.

IMPORTANT: This Letter (together with certificates representing tendered Original Notes or a Book-Entry Confirmation and all other required documents) must be received by the Exchange Agent, or the guaranteed delivery procedures must be complied with, on or before the Expiration Date (as defined in the Prospectus).

PART II: CERTIFICATION

Certification Instructions:  You must cross out item 2 below if you have been notified by the Internal Revenue
Service (the "IRS") that you are currently subject to backup withholding because of underreporting interest or
dividends on your tax return.  However, if after being notified by the IRS that you were subject to backup
withholding you received another notification from the IRS that you are no longer subject to backup withholding,
do not cross out item 2.

Under penalties of perjury, I certify that:

1.   The number shown on this form is my correct TIN or a TIN has not been
     issued to me and either (a) I have mailed or delivered an application to
     receive a TIN to the appropriate IRS Center or Social Security
     Administration Office, or (b) I intend to mail or deliver an application in
     the near future. I understand that if I do not provide my TIN to the payor
     and that, if I do not provide by TIN to the payor within 60 days of
     submitting this Substitute Form W-9, such retained amounts shall be
     remitted to the IRS as backup withholding.

2.   I am not subject to backup withholding because: (a) I am exempt from backup
     withholding, (b) I have not been notified by the IRS that I am subject to
     backup withholding as a result of a failure to report all interest or
     dividends or (c) the IRS has notified me that I am no longer subject to
     backup withholding.

3.  I am a U.S. person (including a U.S. resident alien).

INSTRUCTIONS

FORMING PART OF THE TERMS AND
CONDITIONS OF THE EXCHANGE OFFER

1. DELIVERY OF THIS LETTER AND CERTIFICATES. Certificates for Original Notes or a Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed copy of this Letter and any other documents required by this Letter, must be received by the Exchange Agent at one of its addresses set forth herein on or before the expiration of the exchange offer on the Expiration Date. The method of delivery of this Letter, certificates for Original Notes or a Book-Entry Confirmation, as the case may be, and any other required documents is at the election and risk of the tendering holder, but except as otherwise provided below, the delivery will be deemed made when actually received by the Exchange Agent. If delivery is by mail, the use of registered mail with return receipt requested, properly insured, is suggested.

Holders whose Original Notes are not immediately available or who cannot deliver their Original Notes or a Book-Entry Confirmation, as the case may be, and all other required documents to the Exchange Agent on or before the Expiration Date may tender their Original Notes pursuant to the guaranteed delivery procedures set forth in the Prospectus. Pursuant to such procedure: (i) tender must be made by or through an Eligible Institution (as defined in the Prospectus under the caption "The Exchange Offer - How to Tender"); (ii) prior to the expiration of the exchange offer on the Expiration Date, the Exchange Agent must have received from the Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery (by telegram, telex, facsimile transmission, mail or hand delivery) (x) setting forth the name and address of the holder, the description of the Original Notes and the principal amount of Original Notes tendered, (y) stating that the tender is being made thereby and
(z) guaranteeing that, within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, this Letter together with the certificates representing the Original Notes or a Book-Entry Confirmation, as the case may be, and any other documents required by this Letter will be deposited by the Eligible Institution with the Exchange Agent; and (iii) the certificates for all tendered Original Notes or a Book-Entry Confirmation, as the case may be, as well as all other documents required by this Letter, must be received by the Exchange Agent within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in the Prospectus under the caption "The Exchange Offer - How to Tender."

All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of tendered Original Notes will be determined by the Company, whose determination will be final and binding. The Company reserves the absolute right to reject any or all tenders that are not in proper form or the acceptance of which, in the opinion of the Company's counsel, would be unlawful. The Company also reserves the right to waive any irregularities or conditions of tender as to particular Original Notes. All tendering holders, by execution of this Letter, waive any right to receive notice of acceptance of their Original Notes.

Neither the Company, the Exchange Agent nor any other person shall be obligated to give notice of defects or irregularities in any tender, nor shall any of them incur any liability for failure to give any such notice.

2. PARTIAL TENDERS; WITHDRAWALS. If less than the entire principal amount of any Original Note evidenced by a submitted certificate or by a Book-Entry Confirmation is tendered, the tendering holder must fill in the principal amount tendered in the fourth column of Box 1 above. All of the Original Notes represented by a certificate or by a Book-Entry Confirmation delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated. A certificate for Original Notes not tendered will be sent to the holder, unless otherwise provided in Box 5, as soon as practicable after the Expiration Date, in the event that less than the entire principal amount of Original Notes represented by a submitted certificate is tendered (or, in the case of Original Notes tendered by book-entry transfer, such non-exchanged Original Notes will be credited to an account maintained by the holder with the Book-Entry Transfer Facility).

If not yet accepted, a tender pursuant to the Exchange Offer may be withdrawn prior to the Expiration Date. To be effective with respect to the tender of Original Notes, a notice of withdrawal must: (i) be received by the Exchange Agent before the Company notifies the Exchange Agent that it has accepted the tender of Original Notes pursuant to the Exchange Offer; (ii) specify the name of the person who tendered the Original Notes; (iii) contain a description of the Original Notes to be withdrawn, the certificate numbers shown on the particular

-8-

certificates evidencing such Original Notes and the principal amount of Original Notes represented by such certificates; and (iv) be signed by the holder in the same manner as the original signature on this Letter (including any required signature guarantee).

3. SIGNATURES ON THIS LETTER; ASSIGNMENTS; GUARANTEE OF SIGNATURES. If this Letter is signed by the holder(s) of Original Notes tendered hereby, the signature must correspond with the name(s) as written on the face of the certificate(s) for such Original Notes, without alteration, enlargement or any change whatsoever.

If any of the Original Notes tendered hereby are owned by two or more joint owners, all owners must sign this Letter. If any tendered Original Notes are held in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are names in which certificates are held.

If this Letter is signed by the holder of record and (i) the entire principal amount of the holder's Original Notes are tendered; and/or (ii) untendered Original Notes, if any, are to be issued to the holder of record, then the holder of record need not endorse any certificates for tendered Original Notes, nor provide a separate bond power. If any other case, the holder of record must transmit a separate bond power with this Letter.

If this Letter or any certificate or assignment is signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and proper evidence satisfactory to the Company of their authority to so act must be submitted, unless waived by the Company.

Signatures on this Letter must be guaranteed by an Eligible Institution, unless Original Notes are tendered: (i) by a holder who has not completed the Box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on this Letter; or (ii) for the account of an Eligible Institution. In the event that the signatures in this Letter or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantees must be by an eligible guarantor institution which is a member of The Securities Transfer Agents Medallion Program (STAMP), The New York Stock Exchanges Medallion Signature Program (MSP) or The Stock Exchanges Medallion Program (SEMP) (collectively, "Eligible Institutions"). If Original Notes are registered in the name of a person other than the signer of this Letter, the Original Notes surrendered for exchange must be endorsed by, or be accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by the Company, in its sole discretion, duly executed by the registered holder with the signature thereon guaranteed by an Eligible Institution.

4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders should indicate, in Box 4 or 5, as applicable, the name and address to which the Exchange Notes or certificates for Original Notes not exchanged are to be issued or sent, if different from the name and address of the person signing this Letter. In the case of issuance in a different name, the tax identification number of the person named must also be indicated. Holders tendering Original Notes by book-entry transfer may request that Original Notes not exchanged be credited to such account maintained at the Book-Entry Transfer Facility as such holder may designate.

5. TAX IDENTIFICATION NUMBER. U.S. federal income tax law requires that a holder (other than a person exempt from this requirement as discussed below) whose tendered Original Notes are accepted for exchange must provide the Exchange Agent (as payor) with his or her correct taxpayer identification number ("TIN"), which, in the case of a holder who is an individual, is his or her social security number. If the Exchange Agent is not provided with the correct TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery to the holder of the Exchange Notes pursuant to the Exchange Offer may be subject to back-up withholding. (If withholding results in overpayment of taxes, a refund may be obtained.) Exempt holders (including, among others, all corporations and certain foreign individuals) are not subject to these back-up withholding and reporting requirements.

Under U.S. federal income tax laws, payments made by the Company on account of Exchange Notes issued pursuant to the Exchange Offer may be subject to back-up withholding. In order to prevent back-up withholding, each tendering holder must provide his or her correct TIN by completing the "Substitute Form W-9" in Box 3 certifying that the TIN provided is correct (or that the holder is awaiting a TIN) and that: (i) the holder has not been

-9-

notified by the Internal Revenue Service that he or she is subject to back-up withholding as a result of failure to report all interest or dividends; or (ii) the Internal Revenue Service has notified the holder that he or she is no longer subject to back-up withholding; or (iii) certify in accordance with the "Substitute Form W-9" that such holder is exempt from back-up withholding. Exempt Holders (including, among others, all corporations and certain foreign individuals) are not subject to these back-up withholding and reporting requirements. To prevent possible erroneous back-up withholding, an exempt Holder must check the appropriate box under "Payee Information," enter its correct TIN in Part I of the Substitute Form W-9, and sign and date the form. See the Substitute Form W-9 in Box 3 for additional instructions.

In order for a nonresident alien or foreign entity to qualify as exempt, such person must submit a completed Form W-8BEN, "Certificate of Foreign Status," signed under penalties of perjury attesting to such exempt status. Such forms may be obtained from the Exchange Agent, as payor.

If you do not have a TIN, check the box "Applied For" in Part I of the Substitute Form W-9, consult Part II of the Substitute Form W-9 for instructions on applying for a TIN, and sign and date the form. If you do not provide your TIN to the payor within 60 days, back-up withholding will begin and continue until you furnish your TIN to the payor. Note: Checking the "Applied For" box in Part I of the Substitute Form W-9 indicates that you have already applied for a TIN or that you intend to apply for one in the near future.

If you have any questions concerning the Substitute Form W-9 or any information required therein, please contact the Exchange Agent, as payor.

6. TRANSFER TAXES. The Company will pay all transfer taxes, if any, applicable to the transfer of Original Notes to it or its order pursuant to the Exchange Offer. If, however, the Exchange Notes or certificates for Original Notes not exchanged are to be delivered to, or are to be issued in the name of, any person other than the record holder, or if tendered certificates are recorded in the name of any person other than the person signing this Letter, or if a transfer tax is imposed by any reason other than the transfer of Original Notes to the Company or its order pursuant to the Exchange Offer, then the amount of such transfer taxes (whether imposed on the record holder or any other person) will be payable by the tendering holder. If satisfactory evidence of payment of taxes or exemption from taxes is not submitted with this Letter, the amount of transfer taxes will be billed directly to the tendering holder.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificates listed in this Letter.

7. WAIVER OF CONDITIONS. The Company reserves the absolute right to amend or waive any of the specified conditions in the Exchange Offer in the case of any Original Notes tendered.

8. MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES. Any holder whose certificates for Original Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above, for further instructions.

9. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to the procedure for tendering, as well as requests for additional copies of the Prospectus or this Letter, may be directed to the Exchange Agent.

IMPORTANT: This Letter (together with certificates representing tendered Original Notes or a Book-Entry Confirmation and all other required documents) must be received by the Exchange Agent, or the guaranteed delivery procedures must be complied with, on or before the Expiration Date (as defined in the Prospectus).
