PROSPECTUS SUMMARY

The following summary highlights selected information from this prospectus and may not contain all of the information that is important to you. This prospectus includes specific terms of the securities that are subject to the exchange offer, as well as information regarding our business and detailed financial data. We encourage you to read the prospectus in its entirety. Unless the context clearly indicates otherwise, the terms "we," "our" or "us" as used in this prospectus refer to MidAmerican Funding, LLC, the obligor on your securities. You should pay special attention to the "Risk Factors" section beginning on page 11 of this prospectus.

MIDAMERICAN FUNDING, LLC

We are an Iowa limited liability company that was formed in March 1999 to facilitate the acquisition by MidAmerican Energy Holdings Company (formerly CalEnergy Company, Inc.) of MHC Inc. (formerly MidAmerican Energy Holdings Company). We refer to this acquisition as the merger throughout this prospectus. We are a direct wholly-owned subsidiary of MidAmerican Holdings. We own all of the outstanding common stock of MHC, which owns all of the common stock of MidAmerican Energy Company. We conduct no business other than activities related to the issuance of the securities and the ownership of MHC.

Our principal executive offices are located at 666 Grand Avenue, Des Moines, Iowa 50303, and our telephone number is (515) 242-4000.

MIDAMERICAN HOLDINGS

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

MidAmerican Holdings, headquartered in Des Moines, Iowa, has approximately 9,800 employees and is the largest publicly traded company in Iowa. Through its retail utility subsidiaries, MidAmerican Energy in the United States and Northern Electric plc in the United Kingdom, MidAmerican Holdings provides electric service to 2.2 million customers and natural gas service to 1.2 million customers worldwide. Through CalEnergy Generation, MidAmerican Holdings' independent power production and nonregulated business subsidiary, and MidAmerican Energy's utility operations, MidAmerican Holdings manages and owns interests in approximately 8,300 net megawatts of diversified power generation facilities in operation, construction and development.

On October 25, 1999, MidAmerican Holdings announced that an investor group comprised of Berkshire Hathaway Inc., Walter Scott, Jr. and David L. Sokol had reached agreement to acquire MidAmerican Holdings for $35.05 per share in cash. The purchase price together with the assumption of debt represents a total enterprise value of approximately $9 billion. Upon completion of the transaction, which is expected to occur by April 2000, MidAmerican Holdings would become a privately owned company with publicly traded fixed income securities.

MIDAMERICAN ENERGY AND MHC

MidAmerican Energy is the largest combined electric and gas utility in Iowa with approximately 652,900 electric and 621,500 gas customers. It has gas and electric operations in Iowa, Illinois and South Dakota and gas operations in Nebraska. The regulated service area is comprised of 10,600 square miles with a total population of approximately 1.7 million. MidAmerican Energy owns installed generation capacity of approximately 4,000

1

megawatts, comprised of 71% coal, 19% natural gas and 10% nuclear fuel sources. Due to its geographic location and fuel sources, MidAmerican Energy is a low cost producer of electricity in the Mid-Continent Area Power Pool, which is known as MAPP. From time to time, MidAmerican Energy supplies electricity to other utilities in major energy markets in the midwestern United States, such as the Chicago, St. Louis, Kansas City, Milwaukee and Minneapolis areas. MidAmerican Energy's gas operations are served by at least four major gas pipelines on which MidAmerican Energy has rights to firm and interruptible pipeline capacity. Approximately 88% of the total revenues of MHC in 1998 came from MidAmerican Energy.

MidAmerican Energy is subject to regulation and oversight by one or more of the Federal Energy Regulatory Commission, the Iowa Utilities Board, the Illinois Commerce Commission and other regulatory bodies. These governmental agencies regulate the following aspects of MidAmerican Energy's business, among other things: the issuance of securities, accounting policies and practices, electric interconnections and transmission services, retail rates and affiliate transactions.

MidAmerican Energy is a wholly-owned subsidiary of MHC. In addition to its regulated business conducted through MidAmerican Energy, MHC conducts nonregulated businesses through its subsidiaries MidAmerican Capital Company, Midwest Capital Group and MidAmerican Services Company, including real estate development, financial and energy investments and energy services.

THE MERGER

On March 12, 1999 our subsidiary, MAVH Inc., was merged with and into MHC pursuant to a merger agreement among MidAmerican Holdings, MAVH, MHC and another subsidiary of MidAmerican Holdings. The merger resulted in MHC becoming our direct wholly-owned subsidiary and an indirect wholly-owned subsidiary of MidAmerican Holdings. MidAmerican Holdings paid $27.15 in cash for each outstanding share of MHC common stock for a total of $2.42 billion. The merger was financed with the net proceeds of the initial securities and an equity contribution from MidAmerican Holdings. In connection with the merger, MidAmerican Holdings became an exempt public utility holding company.

                                                   arrangement or understanding with any person to

                                         and September 1.

Collateral..........................     The Securities are secured by a pledge of all of the
                                         common stock of MHC.

Ranking.............................     The Securities:

                                         o   are our direct senior secured obligations;

                                       7

                                         o   rank on an equal basis with all of our other
                                             existing and future senior obligations;

                                         o   rank senior to all of our existing and future
                                             subordinated indebtedness; and

                                         o   effectively rank junior to all indebtedness and other
                                             liabilities, including preferred stock, of our direct
                                             and indirect subsidiaries (to the extent of the assets
                                             of the subsidiaries).

                                         The indenture for the Securities does not restrict the
                                         incurrence of additional unsecured indebtedness by our
                                         subsidiaries and permits our subsidiaries to incur a
                                         significant amount of secured indebtedness. At September
                                         30, 1999, MHC and its direct and indirect subsidiaries had
                                         total indebtedness, including preferred stock, of
                                         approximately $1,316 million, all of which is effectively
                                         senior to the Securities.

Ratings.............................     The Securities have been assigned ratings of BBB+ by
                                         Standard & Poor's Ratings Group, BBB+ by Duff & Phelps
                                         Credit Rating Co. and Baa1 by Moody's Investors Service,
                                         Inc.

Covenants Limiting
      Our Activities................     The indenture contains covenants which, among other things
                                         and subject to exceptions described later in this
                                         prospectus, restrict our ability to:

                                         o    make distributions unless no event of default exists
                                              or would result from the distribution and either:

                                              (1)  at the time and as a result of the distribution, our
                                                   leverage ratio does not exceed 0.67:1 and our interest
                                                   coverage ratio is not less than 2.2:1; or

                                              (2)  at such time our senior secured long term debt is
                                                   rated at least BBB by Standard & Poor's and Duff &
                                                   Phelps, and at least Baa2 by Moody's.

                                         o    enter into any business operations other than:

                                               (1)  the transactions contemplated by the indenture and the
                                                    other financing documents related to the offering of
                                                    the Securities;

                                               (2)  activities related to the management and ownership of
                                                    MHC;

                                               (3)  entering into and performing any agreements to
                                                    accomplish the activities described in clauses (1) and
                                                    (2) above; and

                                               (4)  exercising any corporate powers that are incidental to
                                                    or necessary, suitable or convenient for the
                                                    accomplishment of the activities described in clauses
                                                    (1), (2) and (3) above.

                                       8

                                               However, we may enter into additional business operations
                                               from time to time in the future if, prior to doing so, we
                                               obtain written confirmation from the rating agencies that
                                               the entering into of the new business operations will not
                                               result in a downgrade of the ratings for the Securities.

                                               o    merge or consolidate with or into any other person or
                                                    transfer or lease all or substantially all of our
                                                    assets to another person.

                                               o    incur any indebtedness other than:

                                                    (1)  as a part of our permitted businesses and activities;
                                                         and

                                                    (2)  other indebtedness so long as the rating agencies
                                                         confirm that the incurrence of such indebtedness will
                                                         not result in a downgrade of the ratings for the
                                                         Securities.

                                               o    issue, assume or guarantee indebtedness secured by a
                                                    lien, other than the Securities or any other
                                                    indebtedness issued under the indenture.

                                               The covenants and restrictions which limit our ability to
                                               pay dividends or make other distributions will cease to be
                                               in effect if the rating agencies confirm in writing that,
                                               without these covenants and restrictions, our long-term
                                               senior secured debt would still be rated at least BBB+ by
                                               each of Standard & Poor's and Duff & Phelps and at least
                                               Baa1 by Moody's.

Covenants Limiting the Activities
    of Our Significant Subsidiaries.......     The indenture also restricts, among other things and
                                               subject to exceptions described later in this prospectus,
                                               the ability of our significant subsidiaries to:

                                                o    incur any indebtedness at the MHC level other than
                                                     indebtedness outstanding on the closing date for the
                                                     initial Securities under MHC's existing agreements and
                                                     extensions of this indebtedness.

                                                o    issue, assume or guarantee indebtedness secured by a
                                                     lien, other than liens permitted under the indenture.

                                                o    enter into new businesses and activities other than
                                                     those types of businesses and activities in which we
                                                     are or MidAmerican Energy is engaged today and any
                                                     other business or activity which is deemed necessary,
                                                     useful or desirable in connection with such businesses
                                                     and activities.

                                               The indenture defines a significant subsidiary as any
                                               subsidiary whose gross assets or gross revenues represent
                                               at least 25% of our gross assets or gross revenues.

Optional Redemption.......................     Each series of Securities will be redeemable in whole or
                                               in part at our option at any time at a redemption price
                                               equal to the sum of:


                                       9

                                               o    the greater of:

                                                         Securities being redeemed, and

                                                    (2)  the sum of the present values of the remaining
                                                         scheduled payments of principal of and interest on the
                                                         series of Securities being redeemed, discounted to the
                                                         date of redemption on a semiannual basis at the
                                                         treasury yield (plus 15 basis points in the case of

                                                         the 2029 Securities), plus

                                               o    accrued and unpaid interest on the Securities being

                                  RISK FACTORS

     You should carefully consider the following factors before deciding to
tender your initial Securities in the exchange offer.

YOUR FAILURE TO EXCHANGE YOUR INITIAL SECURITIES FOR EXCHANGE SECURITIES COULD
RESULT IN YOUR HOLDING ILLIQUID SECURITIES WHICH CANNOT BE RESOLD UNLESS YOU
REGISTER THEM UNDER THE SECURITIES ACT OR FIND AN EXEMPTION FROM REGISTRATION.

     The initial Securities were not registered under the Securities Act or
under the securities laws of any state and may not be resold, offered for
resale or otherwise transferred unless they are subsequently registered or
resold pursuant to an exemption from the registration requirements of the
Securities Act and applicable state securities laws. If you do not exchange
your unregistered initial Securities for registered exchange Securities
pursuant to the exchange offer, you will not be able to resell, offer to resell
or otherwise transfer the initial Securities unless they are registered under
the Securities Act or unless you resell them, offer to resell them or otherwise
transfer them under an exemption from the registration requirements of, or in a
transaction not subject to, the Securities Act. In addition, we will no longer
be under an obligation to register the initial Securities under the Securities
Act except in the limited circumstances provided under the registration rights
agreement between us and the initial purchasers of the initial Securities. In
addition, to the extent that initial Securities are tendered for exchange and
accepted in the exchange offer, the trading market for the untendered and
tendered but unaccepted initial Securities could be illiquid.

OUR ABILITY TO MAKE PAYMENTS ON THE SECURITIES IS DEPENDENT ON THE RECEIPT OF
DISTRIBUTIONS FROM OUR SUBSIDIARIES AND OUR SUBSIDIARIES CANNOT MAKE THESE
DISTRIBUTIONS UNTIL THEY MAKE PAYMENTS ON THEIR OWN INDEBTEDNESS.

         We conduct our operations predominantly through MHC and substantially
all of our consolidated assets related to operations are held by MHC and its
subsidiaries. Our ability to pay interest on the Securities is entirely
dependent upon our receipt of dividends and other distributions from MHC and its
subsidiaries. The availability of distributions from our subsidiaries is subject
to the satisfaction of various covenants and conditions contained in the
applicable subsidiaries' existing and future financing documents and to utility
regulatory restrictions. Our subsidiaries, including MHC and MidAmerican Energy,
will not have any obligation to pay any amounts due pursuant to the Securities
or to make any funds available for payment, and do not guarantee any payment on
the Securities. Any right we may have to receive assets of any of our
subsidiaries upon any liquidation or reorganization of the subsidiary would be
effectively subordinated to the claims of any of the subsidiary's creditors and
preferred stockholders.

         The indenture contains limitations on our ability and the ability of
MHC to incur additional secured or unsecured indebtedness. However, the
indenture contains no restrictions on the amount of additional unsecured
indebtedness which may be incurred by our subsidiaries (other than MHC). In
addition, the indenture permits our subsidiaries (other than MHC) to incur
significant additional amounts of secured indebtedness. At September 30, 1999,
MHC and its subsidiaries had total indebtedness, including preferred stock, of
approximately $1,316 million, all of which would be effectively senior to the
Securities.

IF WE DEFAULT UNDER THE INDENTURE AND YOU FORECLOSE ON AND SELL THE STOCK
PLEDGED TO SECURE OUR OBLIGATIONS, THE PRICE YOU RECEIVE FOR THE STOCK MAY NOT
BE SUFFICIENT TO PAY ALL AMOUNTS DUE ON THE SECURITIES.

         The Securities are secured by a pledge of all of the common stock of
MHC. There is currently no market for this stock. We cannot assure you that if
the Securities were to become due and payable because of an event of default
under the indenture that the proceeds from the sale of the MHC stock would be
sufficient to pay all amounts due on the Securities.


                                      11

BECAUSE MIDAMERICAN ENERGY IS OUR WHOLLY-OWNED SUBSIDIARY, WE ARE SUBJECT TO THE
OPERATING UNCERTAINTIES ASSOCIATED WITH UTILITIES.

         The operation of a utility involves many risks, including the breakdown
or failure of power generation equipment, pipelines, transmission lines,
distribution lines or other equipment or processes, fuel interruption, and
performance below expected levels of output or efficiency. Sales and revenues of
a utility may also be adversely affected by general economic and business
conditions and weather conditions in its territory. Each generating facility may
depend on a single or limited number of entities to supply or transport gas,
coal or other fuels, to dispose of wastes or to wheel electricity. The failure
of any of these third parties to fulfill its contractual obligations could have
a material adverse impact on MidAmerican Energy and, accordingly, on us.

THE UTILITY INDUSTRY IN WHICH SOME OF OUR SUBSIDIARIES PARTICIPATE IS UNDERGOING
RESTRUCTURING AS IT IS BEING DEREGULATED, MAKING IT SUBJECT TO INCREASED
COMPETITION.

         Throughout the United States, the utility industry continues to move
towards a competitive environment. Although the extent of deregulation varies
between states, increased competition is becoming a reality in virtually every
region of the country. Numerous states have passed restructuring legislation,
some of which initiated a phase-in of customer choice in 1998. Legislators and
regulators in many other states are addressing the issue.

         As part of many restructuring legislation packages, electric utilities
are required to unbundle traditional services previously provided as a "packaged
product" under their rate tariffs. Unbundling allows customers to choose their
energy supplier and the level of energy delivery and retail services they
desire. Gas utilities are also experiencing separation of the merchant and
delivery functions for all classes of customers.

         The generation segment of the electric industry 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. As retail competition evolves, margins will be pressured by
competition from other utilities, power marketers and self-generation. In
addition, many states 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 anticipated changes in the 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.

         These and other industry restructuring efforts by states in the Midwest
(such as Iowa and Illinois) where MidAmerican Energy has or expects to have
substantial operations could materially impact the results of operations of
MidAmerican Energy and, accordingly, our results of operations, in a manner
which is difficult to predict.

MIDAMERICAN ENERGY IS SUBJECT TO COMPREHENSIVE ENERGY REGULATION BY GOVERNMENTAL
AGENCIES AND THE RECOVERY OF ITS FULL FUEL COSTS IS DEPENDENT ON REGULATORY
ACTION.

         MidAmerican Energy is subject to comprehensive regulation by several
utility regulatory agencies, which significantly influences its operating
environment and its ability to recover its costs from utility customers.
Further, in connection with the approval by the Iowa Utilities Board of the
merger, MHC agreed, among other things, to use all commercially reasonable
efforts to maintain an investment grade credit rating for MidAmerican Energy and
its long-term debt and to seek the approval of the Iowa Utilities Board of a
reasonable utility capital structure if MidAmerican Energy's common equity level
decreases below 42% of total capitalization unless such equity level decreases
to below 39% due to circumstances beyond the control of MidAmerican Energy.

         The regulatory environment presently applicable to MidAmerican Energy
has to date, in general, given MidAmerican Energy an exclusive right to serve
customers within its electric service territory and, in turn, the obligation to
provide electric service to those customers. Base electricity rates for Iowa
customers include a factor


                                      12

which provides for the recovery of a representative level of fuel costs.
However, to the extent actual fuel costs vary from that factor, earnings are
impacted.

         We cannot assure you that regulations described above will not change
or that additional regulations will not become applicable to MidAmerican
Energy's business in the future. Changes in regulations or additional
regulations could have an adverse impact on MidAmerican Energy's results of
operations and, accordingly, our results of operations.

WE AND OUR SUBSIDIARIES ARE SUBJECT TO ENVIRONMENTAL REGULATIONS WHICH COULD BE
DIFFICULT AND COSTLY TO COMPLY WITH.

         We and our subsidiaries are subject to a number of environmental laws
and regulations affecting many aspects of our and our subsidiaries' present and
future operations, including the disposal of various forms of waste, the
construction or permitting of new facilities and air and water quality. These
laws and regulations generally require us and our subsidiaries to obtain and
comply with a wide variety of environmental licenses, permits and other
approvals. We and our subsidiaries are also subject to a number of complex and
stringent environmental laws and regulations that both public officials and
private individuals may seek to enforce. We cannot assure you that existing
environmental regulations will not be revised or that new regulations seeking to
protect the environment will not be adopted or become applicable to us or our
subsidiaries. Revised or additional regulations which result in increased
compliance costs or additional operating restrictions could have a material
adverse effect on our results of operations.

         In particular, regulatory compliance associated with the construction
of new facilities is a costly and time-consuming process. Intricate and rapidly
changing environmental regulations may require major expenditures for permitting
and create the risk of expensive delays or material impairment of project value
if projects cannot function as planned due to changing regulatory requirements
or local opposition.

WE ARE SUBJECT TO THE UNIQUE RISKS ASSOCIATED WITH NUCLEAR GENERATION.

         The risks of nuclear generation risks include (1) the potential harmful
effects on the environment and human health resulting from the operation of
nuclear facilities and the storage, handling and disposal of high-level and
low-level radioactive materials, (2) limitations on the amounts and types of
insurance commercially available to cover losses that might arise in connection
with nuclear operations and (3) 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 and in the event of non-compliance,
has the authority to impose fines or shut down a unit, or both, depending upon
its assessment of the severity of the situation, until compliance is achieved.
Revised safety requirements promulgated by the NRC have, in the past,
necessitated substantial capital expenditures at nuclear plants, including those
with which we have a long-term power purchase contract or in which we have an
ownership interest, such as the Cooper and Quad Cities units, and additional
such expenditures could be required in the future. In addition, although we have
no reason to anticipate a serious nuclear incident at the units in which we have
an interest, if such an incident did occur, it could have a material but
presently undeterminable adverse effect on our financial condition.

WE CANNOT PREDICT THE TYPE OR MAGNITUDE OF POTENTIAL PROBLEMS ASSOCIATED THE
"YEAR 2000" ISSUE AND THESE PROBLEMS COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR
RESULTS OF OPERATIONS.

         The "year 2000" issue arises from the widespread use of computer
programs that rely on two-digit date codes to perform computations or
decision-making functions. Many of these programs may fail due to an inability
to properly interpret date codes beginning January 1, 2000. We and our
subsidiaries have undertaken an extensive ongoing project to address our
information technology and non-information technology (including embedded
technology) systems potentially affected by the year 2000 date change. We and
our subsidiaries have completed both (1) the inventory, assessment and planning
phases for substantially all of our systems and (2) the resolution and

implementation phases for nearly all of our high-and medium-priority systems to
ensure that these systems are suitable for continued use into the year 2000.

         Despite the comprehensive nature of our year 2000 project, it is
possible that MidAmerican Energy may experience random, widespread and/or
simultaneous failures in its generation, transmission and distribution systems
during January 2000. Although MidAmerican Energy is developing contingency plans
for anticipated risks of interruption to the generation or distribution of
energy, we cannot assure you that outages will not occur. Although the impact on
future operations and revenues is unknown, any failure of computer systems to
perform because of year 2000 implications could result in operating problems and
costs that are material to us. Although we believe the compliance project will
be completed sufficiently in advance of January 1, 2000, unforeseen and other
factors could cause delays in the project and/or require material expenditures,
which could have a material adverse effect on our results of operations. In
addition, we cannot assure you that we and our subsidiaries will not be
adversely affected by year 2000 problems experienced by third parties.

THERE IS NO EXISTING MARKET FOR THE EXCHANGE SECURITIES AND WE CANNOT ASSURE YOU
THAT AN ACTIVE TRADING MARKET WILL DEVELOP.

         We are offering the exchange Securities to the holders of the initial
Securities. There is no existing market for the exchange Securities and we
cannot assure you that a market will develop. If a market for the exchange
Securities were to develop, future trading prices would depend on many factors,
including prevailing interest rates, our operating results and the market for
similar securities. We do not intend to apply for listing or quotation of the
exchange Securities on any securities exchange or stock market. As a result, it
may be difficult for you to find a buyer for your Securities at the time you
want to sell them, and even if you found a buyer, you might not get the price
you want.

THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT ARE DEPENDENT ON
CIRCUMSTANCES AND EVENTS WHICH MAY BE OUTSIDE OF OUR CONTROL.

         Some of the statements contained in this prospectus are forward-looking
statements, as defined in Section 21D of the Exchange Act, that are dependent on
circumstances and events that may be outside of our control. We identify these
statements by using words such as "expect," "believe," "anticipate," "estimate"

                               THE EXCHANGE OFFER

WE AGREED WITH THE INITIAL PURCHASERS OF THE INITIAL SECURITIES TO EFFECT THE
EXCHANGE OFFER PURSUANT TO THE REGISTRATION RIGHTS AGREEMENT.

     We sold the initial Securities on March 11, 1999 in a transaction exempt
from the registration requirements of the Securities Act. Credit Suisse First
Boston Corporation and Lehman Brothers Inc., Goldman Sachs & Co. and Merrill
Lynch & Co., as the initial purchasers, subsequently resold the initial
Securities to qualified institutional buyers in reliance on Rule 144A and under
Regulation S under the Securities Act. As of the date of this prospectus,
$700,000,000 aggregate principal amount of unregistered initial Securities are
outstanding.

     We entered into a registration rights agreement with the initial
purchasers under which we agreed that we would, at our own cost:

     []   use our reasonable best efforts to cause the registration statement,
          of which this prospectus is a part, relating to the exchange offer to
          be declared effective by the Securities and Exchange Commission prior
          to December 7, 1999;

     []   keep the exchange offer open for a period of not less than the
          shorter of (1) the period ending when the last of the remaining
          initial Securities is tendered into the exchange offer and (2) 30
          days from the date notice is mailed to holders of the initial
          Securities; and

     []   maintain the registration statement continuously effective for a
          period of not less than the longer of (1) the period until
          consummation of the exchange offer and (2) 120 days after
          effectiveness of the registration statement, subject to extension.
          However, in the event that all resales of exchange Securities covered
          by the registration statement have been made, the registration
          statement need not remain continuously effective.

     The description in this prospectus of provisions of the registration
rights agreement is a summary only and is subject to, and is qualified in its
entirety by, all the provisions of the registration rights agreement, a copy of
which is filed as an exhibit to the registration statement.

THERE WILL BE RESTRICTIONS ON THE ABILITY OF SOME HOLDERS TO RESELL THE EXCHANGE
SECURITIES.

     Based on no-action letters issued by the staff of the Securities and
Exchange Commission to third parties, we believe that a holder of initial
Securities who exchanges initial Securities for exchange Securities in the
exchange offer generally may offer the exchange Securities for resale, sell the
exchange Securities and otherwise transfer the exchange Securities without
further registration under the Securities Act and without delivery of a
prospectus that satisfies the requirements of Section 10 of the Securities Act.
This does not apply, however, to a holder who is an affiliate of ours within
the meaning of Rule 405 of the Securities Act. We also believe that a holder
may offer, sell or transfer the exchange Securities only if the holder acquires
the exchange Securities in the ordinary course of its business and is not
participating, does not intend to participate and has no arrangement or
understanding with any person to participate in a distribution of the exchange
Securities.

     Any holder of initial Securities using the exchange offer to participate
in a distribution of exchange Securities cannot rely on the no-action letters
referred to above. This category of holders includes a broker-dealer that
acquired initial Securities directly from us, but not as a result of
market-making activities or other trading activities. Consequently, this type
of holder must comply with the registration and prospectus delivery
requirements of the Securities Act in the absence of an exemption from these
requirements.

         Each broker-dealer that receives exchange Securities for its own
account in exchange for initial Securities, where the initial Securities were
acquired by the broker-dealer as a result of market-making activities or other
trading activities, may be a statutory underwriter and must acknowledge that it
will deliver a prospectus meeting the


                                      16

requirements of the Securities Act in connection with the resale of exchange
Securities received in exchange for initial Securities. The letter of
transmittal which accompanies this prospectus states that by so acknowledging
and by delivering a prospectus, a participating broker-dealer will not be
deemed to admit that it is an underwriter within the meaning of the Securities
Act. A participating broker-dealer may use this prospectus, as it may be
amended from time to time, in connection with resales of exchange Securities it
receives in exchange for initial Securities in the exchange offer. We will make
this prospectus available to any participating broker-dealer in connection with
any resale of this kind for a period of 30 days after the expiration date of
the exchange offer.

YOU MUST MAKE THE FOLLOWING REPRESENTATIONS AND ACKNOWLEDGEMENTS IN THE LETTER
OF TRANSMITTAL IN ORDER TO EXCHANGE YOUR INITIAL SECURITIES FOR EXCHANGE
SECURITIES.

     Each holder of the initial Securities who wishes to exchange initial
Securities for exchange Securities in the exchange offer will be required to
represent and acknowledge, for the holder and for each beneficial owner of the
initial Securities, whether or not the beneficial owner is the holder, in the
letter of transmittal that:

     []   the exchange Securities acquired pursuant to the exchange offer in
          exchange for initial Securities are being obtained in the holder's
          ordinary course of business;

     []   neither the holder nor any beneficial is engaging in or intends to
          engage in a distribution of exchange Securities;

     []   neither the holder nor any beneficial owner has an arrangement or
          understanding with any person to participate in the distribution of
          exchange Securities;

     []   if the holder or any beneficial owner is a resident of the State of
          California, it falls under the self-executing institutional investor
          exemption set forth under applicable California law;

     []   if the holder or any beneficial owner is a resident of the
          Commonwealth of Pennsylvania, it falls under the self-executing
          institutional investor exemption set forth under applicable
          Pennsylvania law;

     []   any person who is a broker-dealer registered under the Exchange Act,
          or is participating in the exchange offer for the purpose of
          distributing the exchange Securities must comply with the
          registration and prospectus delivery requirements of the Securities
          Act in connection with a secondary resale transaction of the exchange
          Securities or interests therein acquired by such person and cannot
          rely on the position of the staff of the Securities and Exchange
          Commission set forth in certain no-action letters;

     []   it understands that a secondary resale transaction described above
          and any resales of exchange Securities or interests therein obtained
          by the holder in exchange for initial Securities or interests therein
          originally acquired by the holder directly from us should be covered
          by an effective registration statement containing the selling
          security holder information required by Item 507 or Item 508, as
          applicable, of Regulation S-K of the Securities and Exchange
          Commission; and

     []   neither the holder nor any beneficial owner is our "affiliate," as
          such term is defined under Rule 405 promulgated under the Securities
          Act.

WE MAY BE REQUIRED TO FILE A SHELF REGISTRATION STATEMENT COVERING RESALES OF
THE INITIAL SECURITIES.

     If applicable law or interpretations of the staff of the Securities and
Exchange Commission are changed so that the exchange Securities received by
holders who make all of the above representations in the letter of transmittal
are not or would not be, upon receipt, transferable by each holder without
restriction under the Securities Act, we will, at our cost:

                                      17

     o    file a shelf registration statement covering resales of the initial
          Securities,

     o    use our reasonable best efforts to cause the shelf registration
          statement to be declared effective under the Securities Act on or
          prior to December 7, 1999, and

     o    use our reasonable best efforts to keep effective the shelf
          registration statement until the earlier of two years after March 11,
          1999, subject to exceptions, or the time when all of the applicable
          initial Securities are no longer outstanding.

     We may postpone or suspend the filing or the effectiveness of any shelf
registration statement if such action is taken by us in good faith and for
valid business reasons. We will, if and when we file the shelf registration
statement, provide to each holder of the initial Securities copies of the
prospectus which is a part of the shelf registration statement, notify each
holder when the shelf registration statement has become effective and take
other actions as are required to permit unrestricted resales of the initial
Securities.

THE INTEREST RATE ON THE INITIAL SECURITIES WILL INCREASE IF A REGISTRATION
STATEMENT IS NOT DECLARED EFFECTIVE BY DECEMBER 7, 1999.

     In the event that neither the exchange offer registration statement nor a
shelf registration statement has been declared effective by December 7, 1999,
the interest rate on the initial Securities will increase by 0.50% per annum
until the exchange offer registration statement or the shelf registration
statement is declared effective. Upon consummation of the exchange offer,
holders of initial Securities will not be entitled to any increase in the rate
of interest on the initial Securities, but will be entitled to the benefits of
the indenture under which the initial Securities were issued.

THE GENERAL TERMS OF THE EXCHANGE OFFER ARE DESCRIBED IN THE FOLLOWING
PARAGRAPHS.

     We hereby offer, upon the terms and subject to the conditions set forth in
this prospectus and in the accompanying letter of transmittal, to exchange
exchange Securities for a like aggregate principal amount of initial Securities
properly tendered on or prior to the expiration date and not properly withdrawn
in accordance with the procedures described below. We will issue, promptly
after the expiration date, the exchange Securities in exchange for a like
principal amount of outstanding initial Securities tendered and accepted in
connection with the exchange offer. You may tender your initial Securities in
whole or in part in a principal amount of $1,000 and integral multiples of
$1,000, provided that if any initial Securities are tendered for exchange in
part, the untendered principal amount of those initial Securities must be
$100,000 or any integral multiple of $1,000 in excess of $100,000.

     The exchange offer is not conditioned upon any minimum principal amount of
initial Securities being tendered. As of the date of this prospectus,
$700,000,000 aggregate principal amount of the initial Securities is
outstanding.

     If any tendered initial Securities are not accepted for exchange because
of an invalid tender or any other reason, certificates for any unaccepted
initial Securities will be returned, without expense to the tendering holder
thereof promptly after the expiration date.

     You will not be required to pay brokerage commissions or fees or, subject
to the instructions in the Letter of Transmittal, transfer taxes with respect
to the exchange of initial Securities. We will pay all charges and expenses,
other than applicable taxes described below, in connection with the exchange
offer.

     Neither we nor our board of managers makes any recommendation to you as to
whether to tender or refrain from tendering all or any portion of your initial
Securities pursuant to the exchange offer. In addition, no one has been
authorized to make this type of recommendation. You must make your own decision
whether to tender pursuant to the exchange offer and, if you do tender, the
aggregate amount of initial Securities to tender. In making

                                      18

these decisions, you should read this prospectus and the letter of transmittal
and consult with your advisers. You should make the decision whether to tender
based on your own financial position and requirements.

THE EXCHANGE OFFER IS SCHEDULED TO EXPIRE ON [_________], BUT WE HAVE THE
ABILITY TO EXTEND THE EXPIRATION DATE.

     The exchange offer expires on the expiration date. The term "expiration
date" means 5:00 p.m., New York City time, on __________, unless we in our sole
discretion extend the period during which the exchange offer is open. If we do
so, the term "expiration date" will mean the latest time and date to which the
exchange offer is extended. We may extend the exchange offer at any time and
from time to time by giving oral or written notice to the exchange agent and by
timely public announcement. Without limiting the manner in which we may choose
to make any public announcement and subject to applicable law, we will have no
obligation to publish, advertise or otherwise communicate any such public
announcement other than by issuing a release to an appropriate news agency.
During any extension of the exchange offer, all initial Securities previously
tendered pursuant to the exchange offer will remain subject to the exchange
offer.

WE CAN WAIVE CONDITIONS TO THE EXCHANGE OFFER AND AMEND THE EXCHANGE OFFER IN
OTHER WAYS

     We reserve the right (1) to delay accepting any initial Securities, to
extend the exchange offer or to terminate the exchange offer and not accept
initial Securities not previously accepted for any reason, including if any of
the conditions to the exchange offer described below are not satisfied and are
not waived by us, or (2) to amend the terms of the exchange offer in any
manner, whether prior to or after the tender of any of the initial Securities.
If any such delay, extension, termination or amendment occurs, we will give
oral or written notice to the exchange agent and will either issue a public
announcement or give notice to the holders of the initial Securities as
promptly as practicable.

     If (1) we waive any material condition to the exchange offer or amend
the exchange offer in any other material respect and (2) the exchange offer is
scheduled to expire at any time earlier than the expiration of a period ending
on the fifth business day after the date that notice of the waiver or amendment
is first published, sent or given, then the exchange offer will be extended
until the expiration of the five business day period.

FOLLOWING IS A DESCRIPTION OF THE PROCEDURES YOU MUST FOLLOW IN ORDER TO TENDER
YOUR INITIAL SECURITIES IN THE EXCHANGE OFFER.

     THE ITEMS YOU MUST SUBMIT IN ORDER TO TENDER YOUR INITIAL SECURITIES

     To tender in the exchange offer, you must (1) complete, sign and date the
letter of transmittal, or a facsimile thereof, (2) have the signatures thereon
guaranteed if required by the letter of transmittal and (3) mail or otherwise
deliver the letter of transmittal, together with any other required documents
or an agent's message in case of book-entry delivery as described below, to the
exchange agent before the expiration date. In addition, either

     o    certificates for the initial Securities being tendered must be
          received by the exchange agent along with the letter of transmittal
          on or before the expiration date,

     o    a timely confirmation of a book-entry transfer of the initial
          Securities, if this procedure is available, into the exchange agent's
          account at The Depository Trust Company pursuant to the procedure for
          book-entry transfer described below, along with the letter of
          transmittal must be received by the exchange agent on or before the
          expiration date, or

     o    you must comply with the guaranteed delivery procedures described
          below.


                                      19

     THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT YOUR OPTION AND SOLE RISK. IF YOU DELIVER BY
MAIL, WE RECOMMEND REGISTERED MAIL (RETURN RECEIPT REQUESTED AND PROPERLY
INSURED) OR AN OVERNIGHT DELIVERY SERVICE. IN ALL CASES, YOU SHOULD ALLOW
SUFFICIENT TIME TO ENSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR INITIAL
SECURITIES SHOULD BE SENT TO US.

     SPECIAL CIRCUMSTANCES THAT MAY APPLY TO YOUR TENDER

     To be tendered effectively, the initial Securities, letter of transmittal
and all other required documents, or, in the case of a participant in The
Depository Trust Company, an agent's message must be received by the exchange
agent prior to 5:00 p.m., New York City time, on the expiration date. Except in
the case of a participant in The Depository Trust Company who transfers initial
Securities by an agent's message, delivery of all documents must be made to the
exchange agent at its address set forth on the back of this prospectus. You may
also request your respective broker, dealer, commercial bank, trust company or
nominee to effect your tender for you.

     Your tender of initial Securities will constitute an agreement between you
and us in accordance with the terms and subject to the conditions set forth in
the prospectus and in the letter of transmittal. If you tender less than all of
your initial Securities, you should fill in the amount of initial Securities
being tendered in the appropriate box on the letter of transmittal. The entire
amount of initial Securities delivered to the exchange agent will be deemed to
have been tendered unless you indicate otherwise.

     Only a holder of initial Securities may tender initial Securities in the
exchange offer. The term "holder" means any person in whose name initial
Securities are registered on our books or any other person who has obtained a
properly completed bond power from the registered holder.

     Any beneficial owner whose initial Securities are registered in the name
of a broker, dealer, commercial bank, trust company or other nominee and who
wishes to tender should contact the registered holder promptly and instruct the
registered holder to tender on its behalf. If the beneficial owner wishes to
tender on its own behalf, the beneficial owner must, prior to completing and
executing the letter of transmittal and delivering its initial Securities,
either make appropriate arrangements to register ownership of the initial
Securities in the beneficial owner's name or obtain a properly completed bond
power from the registered holder. The transfer of registered ownership may take
considerable time.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a firm (an "eligible institution") that is a
member of a recognized signature guarantee medallion program within the meaning
of Rule 17Ad-15 under the Exchange Act, unless the initial Securities tendered
pursuant thereto are tendered (1) by a registered holder who has not completed
the box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on the letter of transmittal or (2) for the account of an
eligible institution. If signatures on a letter of transmittal or a notice of
withdrawal are required to be guaranteed, the guarantee must be by an eligible
institution.

     If the letter of transmittal is signed by a person other than the
registered holder of any initial Securities listed therein, the initial
Securities must be endorsed or accompanied by bond powers and a proxy which
authorizes such person to tender the initial Securities on behalf of the
registered holder, in each case as the name of the registered holder appears on
the initial Securities. If the letter of transmittal or any initial Securities
or bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such person should so indicate when signing, and
unless waived by us, evidence satisfactory to us of their authority to so act
must be submitted with the letter of transmittal.

     OUR RIGHTS IN CONNECTION WITH THE TENDERING PROCEDURES

     All questions as to the validity, form, eligibility (including time of
receipt) and withdrawal of the tendered initial Securities will be determined
by us in our sole discretion, which determination will be final and binding. We
reserve the absolute right to reject any and all initial Securities not
properly tendered or any initial Securities which,

                                      20

if accepted by us, would be unlawful. We also reserve the right to waive any
irregularities or conditions of tender as to particular initial Securities. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with
tenders of initial Securities must be cured within such time as we determine.
Neither we, the exchange agent or any other person will be under any duty to
give notification of defects or irregularities with respect to tenders of
initial Securities, nor will we or any of them incur any liability for failure
to give notification. Tenders of initial Securities will not be deemed to have
been made until any irregularities have been cured or waived. Any initial
Securities received by the exchange agent that are not properly tendered, and
which have defects or irregularities which have not been timely cured or
waived, will be returned without cost to the holder by the exchange agent as
soon as practicable following the expiration date.

     In addition, we reserve the right in our sole discretion (1) to purchase
or make offers for any initial Securities that remain outstanding subsequent to
the expiration date or to terminate the exchange offer, and (2) to the extent
permitted by applicable law, to purchase initial Securities in the open market,
in privately negotiated transactions or otherwise. We have no present plan to
acquire any initial Securities which are not tendered in the exchange offer.
The terms of any purchases or offers could differ from the terms of the
exchange offer.

YOU MAY BE ABLE TO USE THE DEPOSITORY TRUST COMPANY IN CONNECTION WITH THE
TENDER OF YOUR INITIAL SECURITIES.

     The exchange agent will make a request to establish an account with
respect to the initial Securities at The Depository Trust Company for purposes
of the exchange offer within two business days after the date of this
prospectus. Any financial institution that is a participant in The Depository
Trust Company may book-entry deliver initial Securities by causing The
Depository Trust Company to transfer the initial Securities into the exchange
agent's account at The Depository Trust Company in accordance with The
Depository Trust Company's procedures for transfer on or prior to the
expiration date. If you are a participant in The Depository Trust Company and
transfer your initial Securities by an agent's message, you do not need to
transmit the letter of transmittal to the exchange agent to consummate your
exchange.

     The term "agent's message" means a message transmitted through electronic
means by The Depository Trust Company to and received by the exchange agent and
forming a part of a book-entry confirmation, which states that The Depository
Trust Company has received an express acknowledgment from the participant in
The Depository Trust Company tendering the Securities that the participant has
received and agrees to be bound by the letter of transmittal and/or the notice
of guaranteed delivery discussed below, where applicable.

YOU MAY BE ABLE TO TENDER YOUR INITIAL SECURITIES BY PROVIDING A NOTICE OF
GUARANTEED DELIVERY

     If you would like to tender your initial Securities, and (1) your initial
Securities are not immediately available, (2) time will not permit your initial
Securities or other required documents to reach the exchange agent before the
expiration date, or (3) the procedure for book-entry transfer cannot be
completed on a timely basis, your tender may still be effected if:

     o    the tender is made through an eligible institution;

     o    on or prior to the expiration date, the exchange agent receives from
          the eligible institution a properly completed and duly executed
          letter of transmittal, or in the case of a participant in The
          Depository Trust Company, an agent's message, and notice of
          guaranteed delivery, substantially in the form provided by us, or, in
          the case of a participant in The Depository Trust Company, by an
          agent's message, setting forth your name and address and the amount
          of initial Securities tendered, 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 the notice of guaranteed
          delivery, the certificates for all physically tendered initial
          Securities, in proper form for transfer, or a book-entry
          confirmation, as the case may


                                      21

          be, and any other documents required by the letter of transmittal,
          will be deposited by the eligible institution with the exchange
          agent; and

     o    the certificates for all physically tendered initial Securities, in
          proper form for transfer, or a book-entry confirmation, as the case
          may be, and any other documents required by the letter of transmittal
          are received by the exchange agent within three New York Stock
          Exchange trading days after the date of execution of the notice of
          guaranteed delivery.

     A tender will be deemed to have been received as of the date when your
properly completed and duly signed letter of transmittal accompanied by your
initial Securities is received by the exchange agent, or if you are a
participant in The Depository Trust Company, as of the date when an agent's
message has been received by the exchange agent. Issuances of exchange
Securities in exchange for initial Securities tendered pursuant to a notice of
guaranteed delivery by an eligible institution will be made only against
deposit of the letter of transmittal (and any other required documents) and the
tendered initial Securities.

FOLLOWING IS A DESCRIPTION OF THE TERMS AND CONDITIONS OF THE LETTER OF
TRANSMITTAL. THESE TERMS AND CONDITIONS ARE PART OF THE EXCHANGE OFFER.

     The letter of transmittal contains the following terms and conditions,
among others, which are part of the exchange offer:

     []   You represent and warrant that you have full authority to tender your
          initial Securities.

     []   You agree to, upon our request, execute and deliver any additional
          documents deemed by us to be necessary or desirable to complete the
          tender of your initial Securities.

     []   You acknowledge that the tender of your initial Securities will
          constitute an agreement between you and us as to the terms and
          conditions of the exchange offer described in this prospectus.

     []   You make the representations and warranties described above.

     []   Your obligations under the letter of transmittal will be binding on
          your successors, assigns, executors, administrators, trustees in
          bankruptcy and legal and personal representatives.

YOU MAY WITHDRAW A TENDER OF YOUR INITIAL SECURITIES PRIOR TO THE EXPIRATION
DATE.

     Initial Securities tendered pursuant to the exchange offer may be
withdrawn at any time prior to 5:00 p.m. New York City time, on the expiration
date. For a withdrawal to be effective, a written, telegraphic, telex or
facsimile transmission notice of withdrawal must be timely received by the
exchange agent at its address set forth on the back of this prospectus. Any
notice of withdrawal must specify the name of the person having tendered the
initial Securities to be withdrawn, identify the initial Securities to be
withdrawn, specify the name in which the initial Securities are registered if
different from that of the withdrawing holder, accompanied by evidence
satisfactory to us that the person withdrawing the tender has succeeded to the
beneficial ownership of the initial Securities being withdrawn. If certificates
for initial Securities have been delivered or otherwise identified to the
exchange agent, then, prior to the release of the certificates, the withdrawing
holder must also submit the serial numbers of the particular certificates to be
withdrawn and a signed notice of withdrawal with signatures guaranteed by an
eligible institution unless such holder is an eligible institution. If initial
Securities have been tendered pursuant to the procedure for book-entry transfer
described above, any notice of withdrawal must specify the name and number of
the account at The Depository Trust Company to be credited with the withdrawn
initial Securities and otherwise comply with the Depository Trust Company's
procedures. If any initial Securities are tendered for exchange but are not
exchanged for any reason, or if any initial Securities are submitted for a
greater principal amount than the holder desires to exchange, the unaccepted or
nonexchanged initial Securities will be returned to the

                                      22

holder without cost to the holder as soon as practicable after withdrawal,
rejection of tender, termination of the exchange offer or submission of
nonexchanged initial Securities.

IF YOU WITHDRAW YOUR TENDER, YOU MAY RETENDER YOUR INITIAL SECURITIES PRIOR TO
THE EXPIRATION DATE IN ACCORDANCE WITH THE PROCEDURES FOR TENDERING DESCRIBED
ABOVE.

     Withdrawals of tenders of initial Securities may not be rescinded. Initial
Securities properly withdrawn will not be deemed validly tendered for purposes
of the exchange offer, but may be retendered at any subsequent time on or prior
to the expiration date by following any of the procedures described above.

     All questions as to the validity, form and eligibility (including time of
receipt) of withdrawal notices will be determined by us in our sole discretion,
and our determination will be final and binding on all parties. Neither we, any
affiliates or assigns of ours, the exchange agent nor any other person will be
under any duty to give any notification of any irregularities in any notice of
withdrawal or incur any liability for failure to give any such notification.

FOLLOWING IS A DESCRIPTION OF HOW WE WILL ACCEPT INITIAL SECURITIES AND DELIVER
EXCHANGE SECURITIES.

     Upon the terms and subject to the conditions of the exchange offer, we
will exchange, and will issue to the exchange agent, exchange Securities for
initial Securities validly tendered and not withdrawn promptly after the
expiration date. For the purposes of the exchange offer, we will be deemed to
have accepted for exchange validly tendered initial Securities when and if we
have given oral or written notice thereof to the exchange agent. The exchange
agent will act as agent for the tendering holders of initial Securities for the
purposes of receiving exchange Securities from us and causing the initial
Securities to be assigned, transferred and exchanged. Upon the terms and
subject to the conditions of the exchange offer, delivery of exchange
Securities to be issued in exchange for accepted initial Securities will be
made by the exchange agent only after timely receipt by the exchange agent of
certificates for such initial Securities or a timely book-entry confirmation of
the initial Securities into the exchange agent's account at The Depository
Trust Company, a properly completed and duly executed letter of transmittal and
all other required documents, or, in the case of a book-entry delivery, an
agent's message.

THE CIRCUMSTANCES IN WHICH WE WILL NOT BE REQUIRED TO EFFECT THE EXCHANGE OFFER
ARE DESCRIBED BELOW.

     Notwithstanding any other provisions of the exchange offer, or any
extension of the exchange offer, we will not be required to accept for
exchange, or to exchange, any initial Securities for any exchange Securities,
and, as described below, may terminate the exchange offer (whether or not any
initial Securities have previously been accepted for exchange) or may waive any
conditions to or amend the exchange offer, if any of the following conditions
has occurred or exists or has not been satisfied:

     o    the exchange offer, or the making of any exchange by a holder,
          violates any applicable law or any applicable interpretation of the
          staff of the Securities and Exchange Commission;

     o    in our reasonable judgment there is be threatened, instituted or
          pending any action or proceeding before, or any injunction, order or
          decree has been issued by, any court or governmental agency or other
          governmental regulatory or administrative agency or commission, (1)
          seeking to restrain or prohibit the making or consummation of the
          exchange offer or any other transaction contemplated by the exchange
          offer, (2) assessing or seeking any damages as a result thereof, or
          (3) resulting in a material delay in our ability to accept for
          exchange or exchange some or all of the initial Securities pursuant
          to the exchange offer;

     o    any statute, rule, regulation, order or injunction is sought,
          proposed, introduced, enacted, promulgated or deemed applicable to
          the exchange offer or any of the transactions contemplated by the
          exchange

                                      23

          offer by any government or governmental authority, domestic or
          foreign, or any action will have been taken, proposed or threatened
          by any government, governmental authority, agency or court, domestic
          or foreign, that in our reasonable judgment might directly or
          indirectly result in any of the consequences referred to in clauses
          (1), (2) or (3) immediately above or, in our reasonable judgment,
          might result in the holders of exchange Securities having obligations
          with respect to resales and transfers of exchange Securities which
          are greater than those described in the interpretations of the staff
          of the Securities and Exchange Commission referred to in this
          prospectus, or would otherwise make it inadvisable to proceed with
          the exchange offer;

     o    there will have occurred (1) any general suspension of trading in, or
          general limitation on prices for, securities on the New York Stock
          Exchange, (2) a declaration of a banking moratorium or any suspension
          of payments in respect of banks in the United States or any
          limitation by any governmental agency or authority that adversely
          affects the extension of credit to us, or (3) a commencement of a
          war, armed hostilities or other similar international calamity
          directly or indirectly involving the United States, or, in the case
          any of the foregoing exists at the time of commencement of the
          exchange offer, a material acceleration or worsening thereof; or

     o    a material adverse change will have occurred or be threatened in our
          business, condition (financial or otherwise), operations, stock
          ownership 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. Our failure 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 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.

     In addition, we will not accept for exchange any initial Securities
tendered and no exchange Securities will be issued in exchange for any such
initial Securities, if at such time any stop order will be threatened or in
effect with respect to (1) the registration statement of which this prospectus
constitutes a part or (2) the qualification of the indenture under the Trust
Indenture Act of 1939.

THE BANK OF NEW YORK WILL ACT AS EXCHANGE AGENT FOR THE EXCHANGE OFFER.

     The Bank of New York has been appointed as the exchange agent for the
exchange offer. The Bank of New York also acts as trustee under the indenture.

     Delivery of letters of transmittal and any other required documents and
questions, requests for assistance and requests for additional copies of this
prospectus or the letter of transmittal, should be directed to the exchange
agent at its address and numbers set forth on the back of this prospectus.
Except in the case of a participant in The Depository Trust Company who
transfers initial Securities by an agent's message, delivery to an address
other than as set forth herein, or transmissions of instructions via a
facsimile or telex number other than to the exchange agent as set forth herein,
will not constitute a valid delivery.

     WE ARE REQUIRED TO PAY THE FEES AND EXPENSES DESCRIBED BELOW IN CONNECTION
WITH THE EXCHANGE OFFER.

     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


                                      24

and fiduciaries the reasonable out-of-pocket expenses incurred by them in
forwarding copies of this prospectus and related documents to the beneficial
owners of initial Securities, and in handling tenders for their customers. We
estimate that the expenses we will incur in connection with the exchange offer,
including the fees and expenses of the exchange agent and printing, accounting
and legal fees, will be approximately $200,000.

YOU MAY BE REQUIRED TO PAY TRANSFER TAXES IN CONNECTION WITH YOUR TENDER.

     Holders who tender their initial Securities for exchange will not be
obligated to pay any transfer taxes in connection with the exchange. If,
however, exchange Securities are to be delivered to, or are to be issued in the
name of, any person other than a registered holder of the initial Securities
tendered, or if a transfer tax is imposed for any reason other than the
exchange of initial Securities in connection with the exchange offer, then the
amount of any such transfer taxes (whether imposed on the registered holder or
any other persons) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption from payment is not submitted
with the letter of transmittal, the amount of such transfer taxes will be
billed directly to the tendering holder.

NO ONE ELSE HAS BEEN AUTHORIZED TO PROVIDE YOU WITH INFORMATION REGARDING THE
EXCHANGE OFFER.

     No person has been authorized to give any information or to make any
representations in connection with the exchange offer other than those
contained in this prospectus. If given or made, such information or
representations should not be relied upon as having been authorized by us.
Neither the delivery of this prospectus nor any exchange made under this
prospectus will, 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 in this prospectus.

     The exchange offer is not being made to, nor will tenders be accepted from
or on behalf of, holders of initial Securities in any jurisdiction in which the
making of the exchange offer or the acceptance thereof would not be in
compliance with the laws of the 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
initial Securities in the jurisdiction. In any jurisdiction that has securities
laws or blue sky laws 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 the
jurisdiction.

YOU WILL NOT HAVE APPRAISAL RIGHTS.

     Holders of initial Securities will not have dissenters' rights or
appraisal rights in connection with the exchange offer.

THE FEDERAL INCOME TAX CONSEQUENCES OF YOUR EXCHANGE.

     The exchange of initial Securities for exchange Securities will 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 the
exchange.

                                      25

                                USE OF PROCEEDS

     The exchange offer satisfies an obligation under the registration rights
agreement. We will not receive any cash proceeds from the exchange offer.

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

INTRODUCTION

COMPANY STRUCTURE

The current corporate structure of MidAmerican Funding, LLC (Funding or Company) is the result of the merger transaction completed on March 12, 1999, involving MHC (formerly MidAmerican Energy Holdings Company) and CalEnergy Company, Inc. (CalEnergy). CalEnergy, through a reincorporation transaction, was renamed MidAmerican Energy Holdings Company (Holdings). Funding, a wholly-owned subsidiary of Holdings, acquired all of the outstanding common stock of MHC. Holdings is an exempt public utility holding company headquartered in Des Moines. References to MHC regarding information, events or transactions prior to the merger relate to the former MidAmerican Energy Holdings Company.

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

In October 1999, MHC distributed its investment in MidAmerican Realty to Holdings in conjunction with an initial public offering of common stock of HomeServices.Com, a successor company to MidAmerican Realty.

DESCRIPTION OF FINANCIAL STATEMENTS AND MANAGEMENT'S DISCUSSION AND ANALYSIS

Management's Discussion and Analysis (MD&A) addresses the financial statements of Funding and MHC. The financial statements of Funding include the results of MHC beginning March 12, 1999. Due to its significance, the results for MidAmerican are described specifically in the "Results of Operations" section of MD&A. Information related to MidAmerican also relates to MHC. Information related to MidAmerican Capital and Midwest Capital pertains only to the discussion of the financial condition and results of operations of MHC.

As discussed above, MHC's investment in MidAmerican Realty was distributed to Holdings in October 1999. Accordingly, results of operations for MidAmerican Realty are reflected as discontinued operations for each period and entity presented.

EARNINGS SUMMARY

The following discussion details significant impacts on the results of operations for MHC, the predecessor to Funding, for the years ended December 31, 1998, 1997 and 1996.

Although utility earnings for 1998 were lower than in the prior year, a reduction was anticipated because of the electric pricing settlements achieved in 1996 and 1997 in Iowa and Illinois. Warmer-than-normal temperatures during the heating season also had a negative impact on 1998 earnings. Growth in the number of customers and in other sales factors contributed positively to earnings in 1998. Additionally, MidAmerican's successful performance in the non-retail (off-system) energy market helped offset decreases from weather and reductions in electric retail prices. Utility operating expenses increased as MidAmerican continued strengthening its customer service and marketing capabilities and adding to its information technology resources.

Beginning the second half of 1997 and continuing throughout 1998, MidAmerican charged to expense additional amortization of deferred energy efficiency costs, ongoing energy efficiency costs and certain Cooper Nuclear Station costs consistent with ratemaking treatment. These items significantly increased other operating expenses. In conjunction with expensing these items, MidAmerican began recovery of these costs from its customers, which resulted in additional revenues.

Realized after-tax gains on the sale of McLeodUSA stock and other nonregulated investments not aligned with MHC's corporate vision are also included in 1998 earnings.

DISCONTINUED OPERATIONS

MHC:

31

During 1996, MHC discontinued some of its nonregulated operations. The income or loss from those operations and the losses on disposal are reflected as discontinued operations in each of the periods presented in the Consolidated Statements of Income. Net assets of the discontinued operations are separately presented in the Consolidated Balance Sheets as Investment in Discontinued Operations.

In the fourth quarter of 1996, MHC and KCS Energy, Inc. (KCS) of Edison, New Jersey, signed a definitive agreement to sell a portion of MHC's nonregulated operations to KCS for $210 million in cash and warrants to purchase KCS common stock. The sale, which included MHC's oil and gas exploration and development operations, was completed in January 1997. MHC recorded an after-tax loss of $7.1 million for the transaction in 1996 and an additional $0.9 million in 1997.

In October 1997, MHC also divested a subsidiary that developed and operated a computerized information system which facilitated real-time exchange of power in the electric industry. MHC recorded a $4.0 million anticipated after-tax loss on disposal of those operations in September 1996 and an additional $3.2 million after-tax loss on disposal in September 1997.

In October 1999, MHC distributed its investment in MidAmerican Realty to Holdings in conjunction with an initial public offering of common stock of HomeServices.Com, a successor company to MidAmerican Realty.

MIDAMERICAN:

MidAmerican received $15.3 million in cash in 1996 as final settlement for the sale of a former coal mining subsidiary which was reflected as discontinued operations in 1982 by one of MidAmerican's predecessors. The final settlement included reacquisition by the buyer of preferred equity issued to MidAmerican and the settlement of reclamation reserves. MidAmerican recorded an after-tax loss on disposal of $3.3 million for the transaction in September 1996. This transaction is included in discontinued operations in the consolidated financial statements of MidAmerican as well as MHC. Discontinued operations of MidAmerican includes the net earnings/loss of MidAmerican Capital and Midwest Capital for periods prior to their December 1, 1996, transfer to MHC.

1998 vs 1997 -

Electric gross margin improved $54 million in 1998 compared to 1997. An increase in revenues from energy efficiency cost recovery and the Cooper Tracker (discussed below) accounted for $26.1 million and $2.5 million, respectively, of the increase in margin. Increases in revenues from these factors are substantially offset by increases in other operating expenses.

Regarding the increase in energy efficiency revenues, on September 29, 1997, MidAmerican began recovering from customers its remaining deferred energy efficiency costs and current, ongoing energy efficiency costs. Deferred energy efficiency costs are costs previously incurred by MidAmerican which, in accordance with rate treatment, were not charged to expense until recovery from customers began. Recovery of deferred energy efficiency costs occurs over a four-year period from the date collection begins. Approximately $44.4 million of MidAmerican's 1998 electric revenues were from the recovery of energy efficiency

32

program costs compared to $18.3 million in 1997. Collection of deferred energy efficiency costs will decrease starting in 1999 as various recovery periods are completed. Refer to the discussion under Energy Efficiency in the "Operating Activities and Other Matters" section of MD&A for further discussion.

The Cooper Tracker allows MidAmerican to collect on a current basis the Iowa portion of expenses for Cooper Nuclear Station (Cooper) capital improvement advances. Prior to the Cooper Tracker, which began in July 1997, capital improvement advances were capitalized when incurred and amortized over future periods in accordance with rate treatment.

Electric margin also improved due to an increase in sales volume. In total, electric retail sales for 1998 increased 2.7% compared to 1997. Moderate but steady growth in the number of customers increased electric gross margin by $8.6 million compared to 1997. In addition, an increase in sales that are not dependent on weather contributed $15.5 million to the increase. When compared to normal, the impact of temperatures resulted in an estimated $2 million reduction of electric gross margin for 1998 compared to a $4 million reduction in 1997 - or, a $2 million increase in margin for 1998 compared to 1997. Temperatures in 1998 were warmer-than-normal during the heating seasons and hotter-than-normal during the cooling season.

As anticipated, the effect of rate proceedings in 1996 and 1997 reduced electric gross margin for 1998 compared to 1997. Revenues in 1998 reflect the full-year effect of a June 1997 price reduction for Illinois customers and a small price reduction in August 1998 related to Illinois utility industry restructuring. Prices for Iowa residential customers were reduced $10 million annually in July 1997 and $5 million annually in June 1998. Since July 1997, MidAmerican has reduced prices a total of approximately $10 million annually for its Iowa commercial and industrial customers. The commercial and industrial price reductions were achieved through negotiated contracts, a pilot project and tariffed rate reductions. The combined effect of price reductions decreased revenues and electric margin by $17.0 million for 1998 compared to 1997.

Prior to July 11, 1997, MidAmerican was allowed to recover its energy costs from most of its electric utility customers through energy adjustment clauses (EACs) included in revenues. Effective July 11, 1997, the EAC was eliminated for Iowa customers as part of MidAmerican's Iowa pricing plan. Previously, variations in energy costs did not affect gross margin or net income due to corresponding changes in revenues collected through the EACs. With the elimination of the Iowa EAC, fluctuations in energy costs now may have an impact on gross margin and net income.

Under the Iowa pricing settlement, revenues from off-system sales are considered a component of total energy costs. Accordingly, electric margin in 1998 reflects MidAmerican's strong performance in the off-system market relative to 1997. Margins on off-system sales, which account for most of MidAmerican's sales for resale, contributed $14.2 million more to gross margin in 1998 than in 1997. Though related sales volumes decreased 11.5% compared to the 1997 level, MidAmerican obtained improved margins per unit for the 1998 sales. Refer to comments on the energy market under "Industry Evolution" in the "Operating Activities and Other Matters" section of MD&A.

1997 vs. 1996 -

Electric margin for 1997 increased $25 million compared to 1996. An increase in revenues from energy efficiency cost recovery accounted for $9.0 million of the increase in margin while revenues from the Cooper Tracker totaled $3.9 million in 1997, the first year for that collection mechanism.

Retail sales of electricity increased 2.6% compared to 1996 sales. A moderate but steady growth in the number of customers contributed $11.1 million to the increase in electric gross margin. Compared to 1996, sales and gross margin improved due to the impact of temperatures in MidAmerican's service territory. Although temperatures overall were milder than normal in both years, comparatively, margin for 1997 increased $5 million over 1996 margin due to the effect of weather. When compared to normal, the impact of temperatures

33

resulted in a $4 million reduction of electric gross margin in 1997 compared to a $9 million reduction in the 1996 margin. Additionally, revenues and margin increased due to an improvement in sales not dependent on weather.

As discussed above, the Iowa EAC was eliminated in July 1997. Energy costs per unit for the remainder of 1997 were below the amount recovered in rates under the Iowa pricing plan and resulted in an increase to gross margin. Margins on off-system sales contributed $3.2 million more to electric margin in 1997 than in 1996. Additionally, the 1997 electric margin benefited from a $6.2 million increase in transmission revenues.

In total, price reductions decreased electric gross margin by $21.4 million in 1997 compared to 1996. In addition to the price reductions discussed above, MidAmerican reduced prices for its Illinois customers by $13.1 million annually on November 3, 1996, in conjunction with a rate reduction proceeding. In Iowa, MidAmerican reduced its electric retail prices by $8.7 million effective November 1, 1996. This was the first reduction related to MidAmerican's pricing plan filed in June 1996. Refer to "Rate Matters" in "Liquidity and Capital Resources" later in MD&A for further information regarding prices in Iowa.

1998 vs. 1997 -

MidAmerican's regulated gas revenues include purchase gas adjustment clauses (PGAs) through which MidAmerican is allowed to recover the cost of gas sold from most of its gas utility customers. Consequently, fluctuations in the cost of gas sold do not affect gross margin or net income because revenues reflect comparable fluctuations in revenues from PGAs. A decrease in the 1998 per-unit cost of gas compared to 1997 reduced revenues and cost of gas sold by approximately $59 million. MidAmerican recently made a filing with the IUB that would modify the use of the PGA beginning May 1, 2000. Refer to Small Volume Gas Transportation under the "Operating Activities and Other Matters" section of MD&A for further discussion.

Recovery of gas energy efficiency costs resulted in a $9.2 million increase in revenues and gross margin for 1998 compared to 1997. As discussed in the "Electric Gross Margin" section, on September 29, 1997, MidAmerican began recovery of its deferred energy efficiency costs that had not previously been approved for recovery. Approximately $17.5 million of MidAmerican's 1998 gas revenues were from the recovery of energy efficiency program costs compared to $8.3 million in 1997. Again, increases in revenues from energy efficiency cost recovery are substantially offset by corresponding increases in other operating expenses.

Unusually mild temperatures during the 1998 heating seasons resulted in a decrease in gas margin for 1998. Temperatures in 1998 were 15.6% warmer than normal, reducing gas gross margin in 1998 by an estimated $18 million compared to normal. In 1997, temperatures were closer to normal, resulting in a reduction of the 1997 margin of only $2 million. Comparing the two years then, gas margin decreased $16 million in 1998 due to the variation in temperatures. Customer growth, which contributed $1.6 million to gas margin in 1998, and other sales factors helped mitigate the negative effect of weather on the 1998 margin. In total, retail sales of natural gas in 1998 decreased 12.7% compared to 1997.

1997 vs. 1996 -

Gas gross margin for 1997 decreased $2 million compared to 1996. On a comparative basis, the 1997 gas margin decreased an estimated $10 million due to the effect of weather. Temperatures in 1997 were close to normal, resulting in a $2 million reduction in margin, while temperatures in 1996 were 10.1% colder than normal, contributing $8 million to the 1996 gas gross margin. The decrease in gross margin due to weather was partially

34

offset by a $2.3 million increase from growth in the number of retail customers. In total, retail sales of natural gas in 1997 decreased 7.1% compared to 1996 sales.

Revenues from energy efficiency cost recovery contributed $3.4 million more to gas margin in 1997 than in 1996. Revenues and cost of gas sold increased approximately $25 million in 1997 due to an increase in the average cost of gas per unit compared to 1996.

REGULATED OPERATING EXPENSES

OTHER OPERATING EXPENSES

Regulated other operating expenses increased $32.3 million for 1998 compared to 1997. An increase in energy efficiency costs accounted for $31.6 million of the increase in other operating expenses compared to 1997. Refer to the "Electric Gross Margin" section for further comments on energy efficiency costs.

Operating expenses related to Cooper increased due in part to the ratemaking treatment for Cooper capital improvements, as discussed in the "Electric Gross Margin" section. Cooper capital improvement advances are now expensed when incurred. MidAmerican is recovering the Iowa portion of these costs through the Cooper Tracker, while recovery in Illinois is included in base rates. This change accounted for a $1.7 million increase in nuclear operations costs compared to 1997. Excluding those costs, nuclear operations expenses decreased $8.2 million for 1998 compared to 1997 due to an extended outage at the Quad Cities Station.

MidAmerican continued its focus on customer service and reliability during 1998. Further emphasis on customer service operations and marketing-related efforts, resulted in increases in customer service costs, IT consulting costs, advertising costs and other related expenses. Increases in such expenses accounted for a majority of the remaining increase. The impact of these items was partially offset by a decrease in employee benefits expenses.

Regulated other operating expenses increased $79.4 million in 1997 compared to 1996. Nuclear operating costs increased $14.0 million compared to 1996. Of that increase, $4.5 million related to the change in rate treatment of Cooper capital improvement advances. An increase in energy efficiency costs, including amortization of historical costs and charging expense for current costs, accounted for $13.1 million of the increase in other operating expenses.

MidAmerican's efforts to improve its customer service and reliability resulted in increases in consulting costs, advertising and other related expenses. In addition, 1997 reflects increases in uncollectable accounts expense, employee incentive compensation and certain employee benefits expenses. Other operating expenses for 1997 also reflect an increase in transmission wheeling expense due in part to changes required by FERC Order Nos. 888 and 889.

MAINTENANCE

Maintenance expenses increased $9.4 million in 1998 compared to 1997. An increase in maintenance costs at the Quad Cities Station accounted for $8.0 million of the total. Additionally, MidAmerican incurred repair costs for storms in June 1998, totaling $3.8 million, compared to $2.0 million in 1997 for costs related to a snowstorm in October of that year.

Maintenance expenses increased $9.5 million for 1997 compared to 1996. The main cause of the increase was an adjustment in 1996 to align power plant inventory accounting of predecessor companies which reduced 1996 expense by $6.2 million. Restoration costs for the October 1997 snowstorm also contributed to the increase, while maintenance expenses at the Quad Cities Station decreased $2.5 million in 1997 compared to 1996.

DEPRECIATION AND AMORTIZATION

35

The increase in 1998 expense compared to 1997 is due to additional decommissioning funding for Quad Cities Station, an increase in utility plant and regulatory accruals.

PROPERTY AND OTHER TAXES

Deregulation of the Illinois electric utility industry resulted in changes in the way certain taxes are assessed in Illinois. The changes resulted in a decrease in MidAmerican's tax expense for 1998 compared to 1997. One of the taxes is now assessed directly on the energy consumer instead of through the utility. Accordingly, MidAmerican's electric revenues reflect an equal reduction in 1998. Property taxes increased $8.8 million in 1997 compared to 1996 due primarily to an increase in the assessed value for Iowa property tax purposes.

NONREGULATED OPERATING REVENUES AND OPERATING EXPENSES

MIDAMERICAN:

Revenues and Cost of Sales -

Revenues from wholesale natural gas marketing operations increased $32.5 million in 1998 compared to 1997 due to an increase of 18 million MMBtus (88%) in related sales volumes. A decrease in the average price per unit, reflective of a lower cost of gas per unit, partially offset the effect of increased sales. Cost of sales related to natural gas marketing for 1998 reflects the increase in sales and the decrease in the average cost of gas per unit. Total gross margin (total price less cost of gas) on nonregulated natural gas sales was unchanged compared to 1997.

Other activities contributing to the increase in nonregulated revenues for 1998 relate to work for other utilities and work beyond the meter for customers. In addition, the 1998 amount includes revenues of CBEC Railway, a subsidiary of MidAmerican that operates rail services on a section of railroad track it owns. MidAmerican's revenues in 1998 and 1997 also include pre-tax income from awards for successful performance under its incentive gas procurement program. Under the program, if MidAmerican's cost of gas varies from an established reference price range, then the savings or cost is shared between customers and shareholders. The awards totaled $4.3 million and $4.9 million in 1998 and 1997, respectively.

For the comparison of 1997 with 1996, revenues from wholesale natural gas marketing operations increased $23.1 million due to an increase in sales volumes of 7 million MMBtus (51%). In addition, the average price per unit increased, reflecting an increase in the average cost of gas per unit. Cost of sales related to natural gas marketing for 1997 reflects the increases in sales and the average cost of gas per unit. Total gross margin on nonregulated natural gas sales decreased $0.3 million compared to 1996.

Nonregulated revenues for 1997 also reflect a $2.2 million increase compared to 1996 in MidAmerican's award for performance under its incentive gas procurement program.

Other Nonregulated Operating Expenses -

Other operating expenses increased in 1998 compared to 1997 due to costs related to work for other utilities, costs of work beyond the meter for MidAmerican customers, costs of appliance services and costs of initiatives for new products and services in preparation for deregulation.

The increase in 1997 costs compared to 1996 relates to appliance services and initiatives for new products and services.

MHC:

36

Revenues of MidAmerican Capital and Midwest Capital decreased a total of $163 million in 1998 compared to 1997, primarily due to lower volumetric sales associated with the expiration of wholesale gas contracts which were not replaced. Accordingly, nonregulated cost of gas sold decreased significantly in 1998 from 1997.

Nonregulated other operating expenses for 1998 a decrease of approximately $5.7 million due primarily to administrative costs in 1997 which are no longer incurred because of the absence of operations MHC sold in 1997.

NON-OPERATING INCOME AND INTEREST EXPENSE

MIDAMERICAN:

Interest and Dividend Income-

In December 1997, MidAmerican sold its billed accounts receivable. A portion of the consideration for the sale was a subordinated note from the purchaser. Interest income on that note caused the increase in 1998 compared to 1997. Refer to FINANCING ACTIVITIES, PLANS AND AVAILABILITY later in MD&A for discussion of the sale.

Other, Net -

Other, Net, for 1998 and 1997 reflects the discount on sold accounts receivable, net of a fee for servicing the accounts. The net discount reduced Other, Net by $7.0 million and $0.3 million in 1998 and 1997, respectively.

In September 1997, MidAmerican received a $15 million cash payment from Nebraska Public Power District (NPPD) as settlement for a lawsuit filed by MidAmerican against NPPD. Approximately $12 million was refunded to MidAmerican's customers. The remaining amount was retained by MidAmerican for recovery of litigation costs in the lawsuit. Other, Net for 1997 reflects $2.2 million of pre-tax income for recovery of litigation costs incurred in prior years.

In addition, Other, Net includes the recognition of deferred income from energy efficiency programs totaling $0.2 million, $5.0 million and $3.3 million for 1998, 1997 and 1996, respectively. As discussed in the gross margin sections, MidAmerican started recovery of its remaining deferred energy efficiency costs in September 1997. Accordingly, carrying costs for, or return on, deferred balances are now being collected from customers and are reflected in revenues.

In 1996, MidAmerican recorded an initial pre-tax gain of $3.2 million on its sale of the certain storage gas supplies. MidAmerican recorded an additional $0.8 million gain in the second quarter of 1997 after receiving favorable treatment on the transaction from the Iowa Utilities Board (IUB).

Other, Net for 1997 reflects a net loss on reacquired long-term debt of $0.9 million compared to a $1.1 million net gain in 1996.

Other, Net for 1996 includes approximately $8.7 million of expenses for costs incurred by MidAmerican for its merger proposal to IES Industries Inc. in 1996.

Fixed Charges -

During 1998, MidAmerican reduced its long-term debt through maturities and refinancing. Refer to "Financing Activities, Plans and Availability" later in MD&A for more details.

37

An increase in the average amount of commercial paper outstanding in 1998 compared to 1997 resulted in a decrease in other interest expense for 1998.

Preferred securities of MidAmerican's subsidiary trust were issued in December 1996. MidAmerican preferred shares were reacquired at that time, resulting in the decrease in preferred dividends. Preferred dividends include net gains or losses on the reacquisition of MidAmerican preferred shares. Net losses on reacquisitions totaled $1.4 million and $1.6 million for 1997 and 1996, respectively.

MHC:

Dividend Income -

Dividend income decreased for 1998 due to MidAmerican Capital's reduced holdings of preferred stock.

Realized Gains and Losses on Securities, Net -

Net realized gains on securities for 1998 includes a $14.0 million pre-tax gain on the sale of shares of McLeodUSA common stock. Realized gains on securities in 1997 also includes an $8.0 million pre-tax gain on the sale of shares of McLeodUSA common stock.

Other, Net -

Other, net for 1998 includes a $2.7 million gain on the sale of railcars and a $2.9 million gas on the sale of real estate. During 1997, MHC sold all of the assets of its railcar repair services subsidiary and most of the assets of its railcar leasing subsidiary and recorded pre-tax gains totaling $10.0 million. Write-downs of nonregulated investments decreased Other, net by $15.6 million in 1996.

RESULTS OF OPERATION -- 1999

The following is a discussion of the historical unaudited interim results for Funding and its predecessor MHC for the year to date periods ending September 30, 1999 and 1998. Results for Funding include the results from MHC beginning March 12, 1999, in conjunction with the MidAmerican merger. Certain impacts of the MidAmerican merger are reflected in Funding's results of operations, predominantly interest costs on debt issued by Funding to complete the merger and the effects of purchase accounting, including goodwill amortization and the impacts of fair value adjustments to the carrying value of assets and liabilities. While MHC's results of operations are not included in the results of operations of Funding for all of 1999, management believes that discussion of trends in the ongoing operations that now comprise Funding provides meaningful information.

REGULATED ELECTRIC GROSS MARGIN:

MidAmerican's electric gross margin for the nine-month period ended September 30, 1999, decreased $5 million from the comparable period in 1998. The impact of various factors affecting electric margin are discussed in the following paragraphs.

Collection of deferred energy efficiency costs decreased in 1999 compared to the 1998 period due to the completion of one of the four recovery periods. Changes in revenues from energy efficiency cost recovery are substantially offset by corresponding changes in other operating expenses. Refer to the discussion under "Energy Efficiency" in the "Operating Activities and Other Matters" section of MD&A for further discussion.

Revenues and gross margin for the 1999 periods reflect price reductions which were not in effect, or were only partially in effect, during 1998. In June 1998, revenues from Iowa residential customers were reduced $5 million annually. Since July 1997, MidAmerican has reduced revenues from its Iowa commercial and industrial customers a total of approximately $10 million annually through negotiated contracts and a tariffed rate reduction. These reductions were only partially in effect in the 1998 period. Revenues from Illinois customers were reduced $0.9 million in August 1998 related to Illinois utility industry restructuring. MidAmerican also recorded a refund accrual for a revenue sharing arrangement in Iowa. Refer to "Rate Matters: Electric" in the "Operating Activities and Other Matters" section of MD&A for a discussion of revenue sharing.

38

Temperatures during the nine months ended September 30, 1999, were milder than those for the same period in 1998, reducing electric margin. An increase in sales not dependent on weather and moderate growth in the number of customers increased revenues, significantly offsetting the impact of the mild weather. In total, retail sales of electricity in the first nine months of 1999 were almost equal to those of the same period of 1998.

MidAmerican also sells energy and capacity in the off-system market. Margins on off-system sales, which account for most of MidAmerican's sales for resale, increased primarily due to lower costs per unit of energy sold, which in part is due to the improved availability of Quad Cities Nuclear Station in 1999. Additionally, favorable sales prices during the hot temperatures in July 1999 contributed to the increase.

Deregulation of the Illinois electric utility industry resulted in changes in the way certain taxes are assessed in Illinois. One of the taxes is now assessed directly on the energy consumer instead of through the utility. Accordingly, MidAmerican's electric revenues and electric margin reflect reductions this tax collection change.

REGULATED GAS GROSS MARGIN:

MidAmerican's regulated gas revenues include purchase gas adjustment clauses (PGAs) through which MidAmerican is allowed to recover the cost of gas sold from most of its gas utility customers. Consequently, fluctuations in the cost of gas sold do not affect gross margin or net income because revenues reflect comparable fluctuations in revenues from PGAs. A decrease in the per-unit cost of gas for the nine-months ended September 30, 1999 reduced revenues and cost of gas compared to the same period in 1998.

Recovery of gas energy efficiency program costs decreased for the 1999 nine-month period compared to the same period in 1998. Again, changes in revenues from energy efficiency cost recovery are substantially offset by corresponding changes in other operating expenses. Refer to the discussion under "Energy Efficiency" in the "Operating Activities and Other Matters" section of MD&A for further discussion.

On January 22, 1999, the IUB approved a $6.7 million annual interim increase in gas rates for Iowa retail customers effective immediately. An additional increase was implemented on May 27, 1999, as a result of the IUB's approval of a final rate increase of $13.9 million annually.

Temperatures in the first nine months of 1999 were cooler than 1998, resulting in an increase in gas gross margin for the period. The effect of cooler temperatures and customer growth resulted in an increase in retail sales of natural gas in the first nine months of 1999 compared to the 1998 period, also contributing to the margin improvement.

39

REGULATED OPERATING EXPENSES

Other operating expenses decreased for the nine months ended September 30, 1999, compared to the same period in 1998.

As mentioned in the gross margin discussions, the recovery of one phase of deferred energy efficiency costs is complete, and accordingly, the costs for that phase have been fully amortized to expense. As a result, energy efficiency costs decreased in the nine months ended September 30, 1999 compared to the same period in 1998.

Reductions in gas distribution costs, marketing and sales-related expenses, certain administrative and general costs and customer service costs also contributed to the decrease in other operating expenses in the nine months ended September 30, 1999 compared to the same period in 1998.

Maintenance expenses increased for the nine months ended September 30, 1999 compared to the same period in 1998 due to the timing of generating plant maintenance and an increase in gas distribution maintenance. The increases in these areas were partially offset by a decrease in both 1999 periods for maintenance at the Quad Cities Station.

Property and other taxes decreased for the nine months ended September 30, 1999 compared to the same period in 1998. MidAmerican's Iowa property tax decreased for the 1999 period due to reduced assessed values. Deregulation of the Illinois electric utility industry resulted in changes in the way certain taxes are assessed in Illinois. The changes resulted in decreases in MidAmerican's tax expense for 1999 compared to 1998. One of the taxes is now assessed directly on the energy consumer instead of through the utility. Accordingly, MidAmerican's electric revenues reflect an equal reduction in 1999 for this tax collection change.

NONREGULATED OPERATING REVENUES AND OPERATING EXPENSES

Revenues from nonregulated operations increased for the nine months ended September 30, 1999 compared to the same period in 1998 primarily due to increased sales of wholesale natural gas. Nonregulated cost of sales increased for the same reason.

Revenues for the nine months ended September 30, 1999 reflect revenues from MidAmerican's market access service project, which began in the third quarter of 1999. This pilot project allows customers with at least 4MW of load that are participating in the project to choose their electric power supplier. MidAmerican's revenues from project participants related to non-supply services, such as distribution and transmission, continue to be reflected in regulated electric revenues.

Nonregulated other operating costs increased for the nine months ended September 30, 1999 compared to the same period in 1998, primarily due to amortization of goodwill at Funding associated with the MidAmerican merger. Increased nonregulated operating costs at MidAmerican related to nonregulated marketing initiatives.

40

NON-OPERATING INCOME AND INTEREST EXPENSE

Interest and Dividend Income --

Interest income increased for the nine months ended September 30, 1999 compared to the same period in 1998 due to an increase in temporary cash investments, primarily due to the sale of McLeodUSA common stock described below.

Realized Gains and Losses on Securities, Net --

In May 1999 most of the shares of McLeodUSA common stock held by MHC was sold in a secondary offering. A pre-tax gain of $78.2 million resulting from this transaction is reflected in realized gains and losses on securities, net.

Other Net --

Other, net non-operating income decreased for the nine months ended September 30, 1999 compared to the same period in 1998, primarily due to costs related to the MidAmerican merger accrued at MHC. Additionally, in gains on the sale of nonregulated investments are included in the 1998 period.

Fixed Charges --

Interest on long-term debt increased for the nine months ended September 30, 1999 compared to the same period in 1998. The increase due to primarily to interest on $700 million in debt issued by Funding in conjuction with the MidAmerican merger, partially offset by a decrease in interest expense resulting from debt maturities at MHC in 1999.

LIQUIDITY AND CAPITAL RESOURCES

Funding 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, dividends, debt retirement and other capital requirements.

As reflected on the Consolidated Statements of Cash Flows, MHC had net cash provided from operating activities of $334 million in 1998 compared to $392 million in 1997. For the period ended September 30, 1999 Funding had net cash provided from operating activities of $47.5 million.

INVESTING ACTIVITIES AND PLANS

UTILITY CONSTRUCTION EXPENDITURES

MidAmerican's primary need for capital is utility construction expenditures. For the first nine months of 1999, utility construction expenditures totaled $116 million, including allowance for funds used during construction (AFUDC) and Quad Cities Station nuclear fuel purchases. All such expenditures were met with cash generated from utility operations, net of dividends.

Forecasted utility construction expenditures, including AFUDC, for 1999 are $179 million and $720 million for 2000 through 2003. Capital expenditure needs are reviewed regularly by MidAmerican's management and may change significantly as a result of such reviews. MidAmerican presently expects that all utility construction expenditures for the next five years will be met with 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 regulatory actions.

NUCLEAR DECOMMISSIONING

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

In addition, MidAmerican makes payments to Nebraska Public Power District (NPPD) related to decommissioning Cooper. These payments are reflected in other operating expenses in the Consolidated Statements of Income. NPPD estimates call for MidAmerican to pay approximately $57 million to NPPD for Cooper decommissioning during the period 1999 through 2003. NPPD invests the funds predominately in U.S. Treasury Bonds and other U.S. Government securities. Approximately 20% was invested in domestic corporate debt. MidAmerican's obligation for Cooper decommissioning may be affected by the actual plant shutdown date and the status of the power purchase contract at that time. In July 1997, NPPD filed a lawsuit in United States District Court for the District of Nebraska naming MidAmerican as the defendant and seeking a declaration of MidAmerican's rights and obligations in connection with Cooper nuclear decommissioning funding. Refer to Part II, Item 1. Legal Proceedings, for further discussion of the litigation.

42

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

INVESTMENTS

MidAmerican Capital invests in a variety of marketable securities which it holds for indefinite periods of time. In the Consolidated Statements of Cash Flows, the lines Purchase of Securities and Proceeds from Sale of Securities consist primarily of the gross amounts of these activities, including realized gains and losses on investments in marketable securities.

FINANCING ACTIVITIES, PLANS AND AVAILABILITY

MIDAMERICAN

MidAmerican currently has authority from the FERC to issue short-term debt in the form of commercial paper and bank notes aggregating $400 million. As of September 30, 1999, MidAmerican had a $250 million revolving credit facility agreement and a $5 million bank line of credit. MidAmerican's commercial paper borrowings are supported by the revolving credit facility and the line of credit. MidAmerican also has a revolving credit facility which is dedicated to providing liquidity for its obligations under outstanding pollution control revenue bonds that are periodically remarketed.

In 1997, MidAmerican entered into a revolving agreement, which expires in 2002, to sell all of its right, title and interest in the majority of its billed accounts receivable to MidAmerican Energy Funding Corporation (Funding Corp.), a special purpose entity established to purchase accounts receivable from MidAmerican. Funding Corp. in turn sold receivable interests to outside investors. In consideration for the sale, MidAmerican received $70 million in cash and the remaining balance in the form of a subordinated note from Funding Corp. As of September 30, 1999, the revolving cash balance was $66 million due to a decline during the second quarter of 1999 in accounts receivable available for sale. The agreement is structured as a true sale, as determined by Statement of Financial Accounting Standards (SFAS) No. 125, under which the creditors of Funding Corp. will be entitled to be satisfied out of the assets of Funding Corp. prior to any value being returned to MidAmerican or its creditors. Therefore, the accounts receivable sold are not reflected on MidAmerican's Consolidated Balance Sheets. As of September 30, 1999, $98.6 million of accounts receivable, net of reserves, were sold under the agreement.

MidAmerican has authorization from the FERC to issue up to an additional $500 million in various forms of long-term debt. MidAmerican will also need authorization from the ICC prior to issuing any securities. If 90% or more of the proceeds from a securities issuance are used for refinancing purposes, MidAmerican need only provide the ICC with an "informational statement" prior to the issuance which sets forth the type, amount and use of the proceeds of the securities to be issued. If less than 90% of the proceeds are used for refinancing, MidAmerican must file a comprehensive application seeking authorization prior to issuance. The ICC is required to hold a hearing before issuing its authorization.

MHC:

As of September 30, 1999, MHC had lines of credit totaling $44 million to provide for short-term financing needs, under which no debt was outstanding.

As of September 30, 1999, MidAmerican Capital had unsecured revolving credit facilities in the amount of $6 million, under which no debt was outstanding. MidAmerican Capital has $115 million of long-term debt maturities and sinking fund requirements for 1999 through 2003 related to debt outstanding at September 30, 1999.

Midwest Capital currently has a $25 million line of credit with MidAmerican, of which $5 million was outstanding at December 31, 1998.

OPERATING ACTIVITIES AND OTHER MATTERS

INDUSTRY EVOLUTION

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

In the electric industry, the traditional vertical integration of generation, delivery and marketing is being unbundled, with the generation and marketing functions being deregulated. For local gas distribution businesses, the supply, local delivery and marketing functions are similarly being separated and opened to competitors for all classes of customers. While retail electric competition is presently not permitted in Iowa, MidAmerican's primary market, legislation to do so was introduced in the Iowa legislature in the last session. Deregulation of the gas supply function related to small volume customers is also being considered by the IUB. MidAmerican is actively participating in the legislative and regulatory processes shaping the new environment in which its businesses will operate.

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

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

LEGISLATIVE AND REGULATORY EVOLUTION

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

The law required a 15% electric rate reduction for all Illinois residential customers in 1998. To satisfy its obligation, MidAmerican received credit for its 1996 and 1997 Illinois rate reductions, totaling $15.5 million, and reduced rates an additional $0.9 million annually, effective August 1, 1998. MidAmerican is exempted from the requirement to join an independent system operator (ISO) or to form an in-state ISO.

In addition, the law provides for Illinois earnings above a certain level of ROE to be shared equally between customers and MidAmerican beginning in April 2000. MidAmerican's ROE level will be based on a rolling two-year average, with the first determination being based on an average of 1998 and 1999. The ROE level at which MidAmerican will be required to share earnings is a multi-step calculation of average 30-year Treasury Bond rates plus 5.50% for 1998 and 1999. Legislation passed in July 1999 increases the benchmark for 2000 through 2004 to 8.5% above the 30-year Treasury bond rate. If the resulting average Treasury Bond rate were equal to the December 1998 30-year Treasury Bond rate, the ROE level above which sharing must occur would be approximately 10.6% for 1998 and 1999 and 13.6% for 2000 through 2004. The law allows MidAmerican to mitigate the sharing of earnings above the threshold ROE through accelerated cost recognition that would reduce MidAmerican's earnings. MidAmerican continues to evaluate its strategy regarding the sharing mechanism.

44

The law also addresses charges to customers for transition costs based on a lost-revenue approach. These transition fees, designed to help utilities recover stranded costs, will end December 31, 2006, subject to possible extension. MidAmerican continues its involvement in proceedings which detail the new competitive environment and to evaluate the impact of the law on its operations and the opportunities the law presents.

In Iowa, a replacement of the prior utility property tax system, which was supported by MidAmerican, went into effect on January 1, 1999. The replacement tax is primarily a consumption-based tax on the user of energy and assures stability in tax collections as the industry is deregulated in Iowa. With resolution of the utility property tax issue, MidAmerican is pursuing the adoption of electric utility industry restructuring legislation. Progress was made during the 1999 Iowa legislative session, and MidAmerican continues working toward adoption of new legislation in a future session.

RESIDENTIAL AND COMMERCIAL PILOT PROJECT

On August 21, 1998, the IUB issued an Order approving MidAmerican's proposal to allow at least 15,000 Iowa families and 2,000 small businesses to have the opportunity to select among competing electricity providers. The two-year pilot program will allow participating retail customers in the selected test area to choose among several electricity providers, including MidAmerican, and to have that energy delivered by MidAmerican. Customer enrollment is currently allowed and the pilot may begin in 1999 should additional suppliers register. Businesses in the test area will be eligible for the program if their annual peak demand is less than four megawatts. New suppliers participating in the program will have to be certified by the IUB and meet specified requirements.

ACCOUNTING EFFECTS OF INDUSTRY RESTRUCTURING

A possible consequence of competition in the utility industry is that SFAS 71 may no longer apply. SFAS 71 sets forth accounting principles for operations that are regulated and meet certain criteria. For operations that meet the criteria, SFAS 71 allows, among other things, the deferral of costs that would otherwise be expensed when incurred. A majority of MidAmerican's electric and gas utility operations currently meet the criteria required by SFAS 71, but its applicability is periodically reexamined. On December 16, 1997, MidAmerican's generation operations serving Illinois were no longer subject to the provisions of SFAS 71 due to passage of industry restructuring legislation in Illinois. Thus, in 1997 MidAmerican was required to write off the regulatory assets and liabilities from its balance sheet related to its Illinois generation operations. The net amount of such write-offs was not material. If other portions of its utility operations no longer meet the criteria of SFAS 71, MidAmerican could be required to write off the related regulatory assets and liabilities from its balance sheet, and thus, a material adjustment to earnings in that period could result. As of September 30, 1999, MidAmerican had $266 million of regulatory assets on its Consolidated Balance Sheet.

ENERGY EFFICIENCY

MidAmerican's regulatory assets as of September 30, 1999, included $47.9 million of deferred energy efficiency costs. Based on the current level of recovery, MidAmerican expects to recover these costs by the end of 2001. MidAmerican is also allowed to recover its ongoing energy efficiency costs on a current basis. Recovery of these costs is being collected from customers based on projected annual costs of $17.4 million, which may be adjusted annually. Amortization of the deferred energy efficiency costs and current expenditures for energy efficiency costs will be reflected in other operating expenses over the related periods of recovery. The total of such costs for the years 1999, 2000 and 2001 is estimated to be $43 million, $40 million and $35 million, respectively.

RATE MATTERS: ELECTRIC

Through several steps from mid-1997 to the end of 1998, electric prices for Iowa industrial customers were reduced by an amount which will have a $6 million annual impact on revenues, and electric prices for Iowa commercial customers were reduced by an amount which will have a $4 million annual impact on revenues. The

45

reductions were achieved through a retail access pilot project, negotiated individual electric contracts and a $1.5 million tariffed rate reduction for certain non-contract commercial customers.

The negotiated electric contracts have differing terms and conditions as well as prices. The contracts range in length from five to ten years, and some have price renegotiation and early termination provisions exercisable by either party. The vast majority of the contracts are for terms of seven years or less, although, some large customers have agreed to ten-year contracts. Prices are set as fixed prices; however, many contracts allow for potential price adjustments with respect to environmental costs, government imposed public purpose programs, tax changes, and transition costs. While the contract prices are fixed (except for the potential adjustment elements), the costs MidAmerican incurs to fulfill these contracts will vary. On an aggregate basis the annual revenues under contract are approximately $180 million.

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

RATE MATTERS: GAS

In October 1998, MidAmerican made a filing with the IUB requesting a rate increase for its Iowa retail gas customers. An interim rate increase of approximately $6.7 million annually was approved by the IUB on January 22, 1999, effective immediately. On April 23, 1999, the IUB issued an order approving a settlement agreement between MidAmerican, the OCA and other parties which provides for an annual increase of $13.9 million. The new rates were implemented May 27, 1999.

In November 1998, MidAmerican filed with the South Dakota Public Utilities Commission (SDPUC) requesting a rate increase for its South Dakota retail gas customers. The SDPUC in April 1999 approved a rate increase of $2.4 million annually, effective May 1, 1999.

On September 1, 1999, MidAmerican filed with the ICC requesting a rate increase totaling $3.2 million annually for its Illinois retail gas customers. An ICC decision is anticipated prior to August 2000.

ENVIRONMENTAL MATTERS

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

MidAmerican is evaluating 27 properties which were, at one time, sites of gas manufacturing plants in which it may be a PRP. The purpose of these evaluations is to determine whether waste materials are present, whether such materials constitute an environmental or health risk, and whether MidAmerican has any responsibility for remedial action. MidAmerican's estimate of probable remediation costs for these sites as of September 30, 1999, was $21 million. This estimate has been recorded as a liability and a regulatory asset for future recovery through the regulatory process. Refer to Note B (1) of Notes to Consolidated Financial Statements for further discussion of MidAmerican's environmental activities related to MGP sites and cost recovery.

46

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

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

On July 18, 1997, the EPA adopted revisions to the NAAQS for ozone and a new standard for fine particulate matter. Based on data to be obtained from monitors located throughout the states, the EPA will make a determination of whether the states have any areas that do not meet the air quality standards
(i.e., areas that are classified as nonattainment). If a state has area(s)
classified as nonattainment area(s), the state is required to submit a State Implementation Plan specifying how it will reach attainment of the standards through emission reductions or other means.

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

In December 1997, negotiators from more than 150 nations met in Kyoto, Japan to negotiate an international agreement designed to address global climate change impacts by attempting to reduce so-called greenhouse gas emissions. Some scientists contend that these gases build up in the Earth's atmosphere and cause global temperatures to rise. The primary target of these emissions is carbon dioxide (CO2) which is formed by, among other things, the combustion of fossil fuels. The agreement currently calls for the United States to reduce its emissions of CO2 and other greenhouse gases to 7% below 1990 levels in the 2008-2012 time frame. The United States became a signatory to the agreement on November 12, 1998. In order for the agreement to become binding upon the United States, ratification by the U.S. Senate is necessary. The cost to the utility industry in general, and to MidAmerican, of reducing its CO2 emissions levels by 7% below 1990 levels would depend on available technology at the time, but could be material.

QUAD CITIES NUCLEAR POWER STATION

Quad Cities Station is operated by, and 75% owned by, Commonwealth Edison Company (ComEd). On May 6, 1999, the Nuclear Regulatory Commission (NRC) advised ComEd that it had classified Quad Cities Station in the NRC's Routine Oversight category (the best of the NRC's three new categories) for nuclear power plants, removing the station from the Trending (adversely) Letter status initiated in January 1998. During the first nine months of 1999, the station capacity factor was in excess of 93.5%.

GENERATING CAPABILITY

In July 1999, retail customer usage of electricity caused an hourly peak demand of 3,833 MW on MidAmerican's energy system. MidAmerican is interconnected with certain Iowa and neighboring utilities and is involved in an electric power pooling agreement known as Mid-Continent Area Power Pool (MAPP). Each MAPP participant is required to maintain for emergency purposes a net generating capability reserve of at least 15% above

47

its system peak demand. MidAmerican was able to maintain its capacity reserve requirement during the hot weather in July 1999 and was not adversely affected by the resultant high prices in the off-system market.

MidAmerican believes it has adequate electric capacity reserve and continues to manage its generating resources to ensure an adequate reserve in the future. However, significantly higher-than-normal temperatures during the cooling season could cause MidAmerican's reserve to fall below the 15% minimum. If MidAmerican fails to maintain the appropriate reserve, significant penalties could be contractually imposed by MAPP.

ACTIVITIES REGARDING YEAR 2000 DATE ISSUES

The following discussion of year 2000 issues describes MidAmerican's plans to address technical problems relating to calculations, manipulations, storage and other uses of date-sensitive data which could cause some computer-controlled systems, applications and processes (hereinafter referred to as "Systems") to incorrectly process critical financial and operational information, or stop processing altogether. The discussion contains by necessity many forward-looking statements. MidAmerican wishes to avail itself of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, and in order to do so includes the following meaningful cautionary statements with regard to the forward looking statements of its year 2000 plans. MidAmerican's intentions, expectations, and predictions relating to its year 2000 efforts are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, such statements. Such risks and uncertainties include, among others, the effects of weather, federal and state regulatory actions, and other matters, many of which are beyond MidAmerican's control. In addition, MidAmerican claims the full protections established by the Year 2000 Information and Readiness Disclosure Act for Year 2000 Statements and Year 2000 Readiness Disclosure.

PROJECT DESCRIPTION

MidAmerican has undertaken an extensive ongoing project to address its information technology (IT) and non-IT (including embedded technology) Systems potentially affected by the year 2000 date change. MidAmerican's approach is based on a five-phase project methodology - inventory, assessment, planning, resolution and implementation - designed to result in the identification and evaluation of potential problems, and remediation of MidAmerican's Systems. MidAmerican generally defines the five phases as follows:

1. Inventory Phase - The purpose of the inventory phase is to identify and document Systems used by MidAmerican that may have a date-sensitive function.

2. Assessment Phase - The purpose of the assessment phase is to collect information about inventoried Systems, including the business and technical context in which individual Systems operate, to make an informed judgment concerning an appropriate plan to mitigate year 2000 related risks.

3. Planning Phase - The purpose of the planning phase is to develop strategic and tactical plans for Systems that require replacement, repairs, upgrades or other appropriate actions (collectively referred to as "remedial actions").

4. Resolution Phase - The purpose of the resolution phase is to execute the plan developed during the preceding phases. Testing of Systems and/or components of Systems, as well as any preceding or subsequent remedial action, is commenced during this phase.

5. Implementation Phase - The purpose of the implementation phase is to examine the Systems to determine whether they will function adequately in a production environment and to perform follow-up administrative tasks as required to develop appropriate documentation in support of year 2000 readiness.

MidAmerican classifies all Systems ranging from low- to high-priority based on their importance to carrying out MidAmerican's business mission. System priority is based on potential impacts resulting from year

48

2000 problems on public and employee safety, prolonged and widespread service outages, long-term shareholder value, and ability to comply with regulatory requirements. In the case of low-priority Systems, year 2000 readiness may be delayed beyond January 1, 2000, or perhaps indefinitely. MidAmerican plans to use the last two months of 1999 to perform post-implementation testing, address selected lower priority Systems and conduct preparedness exercises.

Vendors, customers and other third parties may affect MidAmerican's ability to achieve year 2000 readiness. Because service reliability and financial stability are dependent on MidAmerican's supply chain, a concerted effort is being made to investigate important third parties to assess their ability to continue to supply products or services to, or purchase products or services from, MidAmerican.

STATE OF READINESS

Due to factors such as the overlapping nature of the project phases and the varying degree of complexity of the Systems being addressed, it is difficult to accurately determine the status of completion of a particular phase of the project at any given point in time. MidAmerican uses three methods to measure the status of project completion:

1. As an entity with public utility operations, MidAmerican must comply with certain year 2000 regulatory requirements imposed by the North American Electric Reliability Council (NERC). NERC reporting data is limited primarily to Systems that are directly associated with transmission grid stability. The transmission grid consists of the interconnected transmission systems of North American utilities. Reporting categories include nuclear generation, non-nuclear generation, Energy Management Systems and Supervisory Control and Data Acquisition (SCADA) system, telecommunications systems, substation controls and system protection, and IT business information systems. MidAmerican reported in its July compliance filing with NERC that it is "100% Y2K Ready" on systems considered mission-critical by NERC definition.

2. A "checklist" approach is used to monitor the completion status of each System that is unique to a given organizational group. For example, identical substation meters may be located in several individual substations, but the meter is counted as only one System. All Systems are viewed as equivalent, regardless of priority, in the checklist approach. Systems are categorized as complete or not complete, without regard to percentage of completion of the System in total or percentage of completion of any particular phase of the project. As of September 30, 1999, there were 5,554 separate Systems in MidAmerican's inventory. Of these, over 99% had been completed.

3. MidAmerican's internally developed measure is more sensitive than the methods discussed above and is based on business risk/priority, weighted tasks and weighted phases. Only high- and medium-risk/priority Systems are included in the status of completion calculation. The data related to Systems that could impact grid stability pertains only to those Systems that directly affect MidAmerican's customers. Also, progress toward completion is measured. As of September 30, 1999, MidAmerican as a whole is generally in the resolution phase. Percentage of completion for six areas of business operations is a follows:

A. IT - Applications: 95-100% complete
B. IT - Operations & Infrastructure: 95-100% complete
C. Generation: 95-100% complete
D. Energy Delivery: 95-100% complete
E. Retail: 95-100% complete
F. Corporate Services (excluding IT): 95-100% complete

The investigation of supply chain issues consists of documenting the nature of business relationships in correspondence, surveys and meetings with third parties and making determinations regarding their year 2000 readiness status based on the responses received. MidAmerican has initiated contact with vendors and business partners it considers to represent a significant financial or operational risk if they were to experience year 2000

49

problems. In addition, interconnected utilities and wholesale customers, as well as high-volume retail customers, have been contacted for the purpose of reviewing the status of their year 2000 readiness efforts. To date, information made available to MidAmerican has not been uniform in terms of quality and quantity. Although none of the information has suggested that the year 2000 readiness efforts of these vendors, business partners and customers have been inadequate, MidAmerican intends to maintain ongoing communications with some third parties through the few months of 1999. MidAmerican will also continue monitoring information about specific products in MidAmerican's inventory.

COSTS

As of September 30, 1999 approximately $10.2 million in operating expenses have been incurred to carry out year 2000 activities. It is anticipated that up to $2.8 million in additional operating expenses and capital costs will need to be incurred to complete the project. Although additional unforeseen costs may be incurred, at this time MidAmerican has not become aware of any material costs which may arise in order to achieve year 2000 readiness. Future progress toward achievement of year 2000 readiness could change this outlook.

MidAmerican has renovated or replaced several high-priority Systems (e.g., management information, materials management information, work management information, customer service, electric outage management, meter control and inventory, and others) to gain enhanced functionalities. For example, the development and installation of a new customer service system (CSS) and related applications was an outcome of the merger which created MidAmerican in July of 1995. Although potential year 2000 problems existing in the predecessor companies' CSS products were recognized, the decision to implement the new CSS was primarily in response to integration difficulties and the need for additional application functionalities. The costs of these renovations and replacements are not reported herein as their development and installation was not driven by year 2000 concerns.

CONTINGENCY PLANS

A contingency plan identifying credible worst-case scenarios has been developed. The contingency plan is comprised of both mitigation and recovery aspects. Mitigation entails planning to reduce the impact of unresolved year 2000 problems, and recovery entails planning to restore services in the event that year 2000 problems occur. MidAmerican's contingency plan has been reviewed by senior management. Although the plan is substantially complete, it will be refined throughout the remainder of the year based on results of contingency planning drills and changes in circumstances.

Although a number of factors come into play in defining reasonably likely worst case scenarios, the loss of voice and data communications, volatile load patterns, and inability to control generation and/or return generation units to service are viewed as the most serious threats. The relative seriousness of these threats is based on recognition that the occurrence of any of these types of problems could have an immediate and significant effect on service reliability and financial performance.

MidAmerican participated in contingency planning drills coordinated by NERC on April 9, 1999 and September 8-9, 1999. The drills focused on managing problems resulting from a simulated partial loss of voice and data communications services. During those drills, MidAmerican did not experience any unexpected results.

RISKS

Despite the comprehensive nature of MidAmerican's year 2000 project and the results the project is designed to produce, MidAmerican may experience random, widespread and simultaneous failures in its generation, distribution and Systems during year 2000 transition periods. Contingency plans for any known or reasonably anticipated risk of interruption to the generation or distribution of energy are being developed to plan for resources needed to be put in place to reduce the potential outage period to a minimum. Although the impact on future operations and revenues is unknown, failure of MidAmerican's Systems to perform because of year 2000 implications could result in operating problems and costs material to MidAmerican.

Although management believes the project will be completed sufficiently in advance of January 1, 2000, unforeseen and other factors could cause delays in the project, the results of which may have a material effect on MidAmerican's results of operations. In addition, there is no assurance that MidAmerican will not be affected by year 2000 problems experienced by third parties.

ACCOUNTING ISSUES

In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS 133, "Accounting for Derivative Instruments and Hedging Activities", which was delayed by SFAS 137 and is effective for fiscal years beginning after June 15, 2000. SFAS 133 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. The Company is in the process of evaluating the impact of this accounting standard.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

MidAmerican is exposed to market risk, including changes in the market price of certain commodities. To manage the price volatility relating to these exposures, MidAmerican enters into various financial derivative instruments. A Risk Management Committee governs the overall direction, structure, conduct and control of the Company's risk management activities, including the use of financial derivative instruments. Responsibilities of the Risk Management Committee include 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.

MidAmerican uses hedge accounting for commodity-related instruments pertaining to its natural gas purchasing operations.

COMMODITY PRICE RISK

Regulated Natural Gas Operations-

Under the current regulatory framework, MidAmerican is allowed to recover in revenues the cost of gas sold from most of its regulated gas customers through a purchased gas adjustment clause (PGA). MidAmerican derived approximately 94% of its regulated gas revenues from such customers in 1998. Since the majority of MidAmerican's firm natural gas supply contracts contain pricing provisions based on a daily or monthly market index, MidAmerican's regulated gas customers, although ensured of the availability of gas supplies, retain the risk associated with market price volatility.

MidAmerican enters into natural gas futures and swap agreements to mitigate a portion of the market risk retained by its regulated gas customers through the PGA. These financial derivative activities are recorded as hedge accounting transactions, with net amounts exchanged or accrued under swap agreements and realized gains or losses on futures contracts included in the cost of gas sold and recovered in revenues from regulated gas customers. At December 31, 1998, MidAmerican had entered into the following financial derivative instruments for regulated operations:

Futures Contracts:
         Net Contract Volumes- Long (Short)                    (240,000) MMBtu
         Unrealized Gain (Loss) at 12/31/98 (in thousands)      $(1,843)

Swap Contracts:
         Contract Volumes                                      7,200,000 MMBtu
         Unrealized Gain (Loss) at 12/31/98 (in thousands)          $225

A $0.05 increase in underlying natural gas prices would increase unrealized losses on the above futures contracts by approximately $12,000 and would increase unrealized gains on the above swap contracts by approximately $360,000.

51

Nonregulated Natural Gas Operations-

MidAmerican 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 enters into natural gas futures and swap agreements to offset the financial impact of variations in natural gas commodity prices for physical delivery to non-regulated customers. These financial derivative activities are recorded as hedge accounting transactions, with net amounts exchanged or accrued under swap agreements and realized gains or losses on futures contracts included in the cost of gas sold. At December 31, 1998, MidAmerican had entered into the following financial derivative instruments for non-regulated operations:

Futures Contracts:
         Net Contract Volumes- Long (Short)                   (110,000) MMBtu
         Unrealized Gain (Loss) at 12/31/98 (in thousands)         $28

Swap Contracts:
         Contract Volumes                                     9,122,181 MMBtu
         Unrealized Gain (Loss) at 12/31/98 (in thousands)      $(3,121)

A $0.05 increase in underlying natural gas prices would decrease unrealized gains on the above futures contracts by approximately $6,000 and would decrease unrealized losses on the above swap contracts by approximately $456,000. Unrealized gains and losses on financial derivatives entered into for nonregulated operations have little ultimate impact on MidAmerican's earnings and cash flow as these amounts are offset by corresponding changes in the theoretical value of underlying contracts for physical delivery of natural gas to nonregulated customers.

1997 Total Natural Gas Operations-

At December 31, 1997, MidAmerican had entered into the following financial derivative instruments for natural gas operations:

Futures Contracts:
         Net Contract Volumes- Long (Short)                 2,000,000 MMBtu
         Unrealized Gain (Loss) at 12/31/97 (in thousands)      $(386)

Swap Contracts:
         Contract Volumes                                   6,968,807 MMBtu
         Unrealized Gain (Loss) at 12/31/97 (in thousands)      $(885)

INTEREST RATE RISK

The Company is exposed to market value risk from changes in interest rates on its preferred stock investments. The Company reviews the interest rate sensitivity of these securities and purchases put options and enters into "short" positions in futures contracts on U.S. Treasury securities for other than trading purposes in order to reduce related interest rate risk. The Company's intent is to manage the risk arising from changes in the general level of interest rates with a change in market value of the hedging instruments. The Company does not purchase or sell hedging instruments for speculative purposes.

The following table demonstrates the impact of varying interest rate changes to the market value at December 31, 1998: (amounts in millions)

The number of hedging instrument contracts entered into, or their notional amount, is dependent on, among other things, the duration of the portfolio, specific call provisions of each fixed rate preferred stock, the slope of the Treasury yield curve, the expected volatility of Treasury yields and the cost of using futures and/or options. The notional amount of the Company's hedging instruments at December 31, 1998 and 1997, respectively are set forth in the following table:

OUR BUSINESS AND THE BUSINESS OF MHC AND MIDAMERICAN ENERGY

OUR BUSINESS

We were formed as an Iowa limited liability company on March 9, 1999 to issue the initial Securities and facilitate the merger. MidAmerican Holdings is our sole member. We currently own all of the outstanding common stock of MHC. We do not engage in any business other than activities associated with the issuance of the Securities and the ownership of MHC.

THE BUSINESS OF MHC

MHC is an exempt public utility holding company headquartered in Des Moines, Iowa, and incorporated in the State of Iowa. MHC's interests include:

[] 100% of the common stock of MidAmerican Energy;

[] 100% of the common stock of MidAmerican Capital;

[] 100% of the common stock of Midwest Capital; and

[] 100% of the common stock of MidAmerican Services.

MidAmerican Energy is primarily engaged in the business of generating, transmitting, distributing and selling electricity and distributing, selling and transporting natural gas. MidAmerican Capital manages marketable securities and passive investment activities, nonregulated wholesale and retail natural gas businesses, security services and other energy-related, nonregulated activities. Midwest Capital functions as a regional business development company in MidAmerican Energy's service territory. MidAmerican Services, which was formed in April 22, 1997, provides comprehensive energy services to utilities and other companies.

Prior to the initial public offering described below, MidAmerican Holdings' real estate brokerage and related services were conducted through MHC's subsidiary, MidAmerican Realty Services. On October 14, 1999, HomeServices.Com, the successor to MidAmerican Realty, sold 35% of its common stock in an initial public offering. The remaining 65% is owned by MidAmerican Holdings.

For the nine months ended September 30, 1999, 93% of MHC's operating revenues (excluding MidAmerican Realty Services) were from MidAmerican Energy, 4% were from MidAmerican Capital and 3% were from Midwest Capital. For the year ended December 31, 1998, 95% of MHC's operating revenues (excluding MidAmerican Realty Services) were from MidAmerican Energy, 5% were from MidAmerican Capital and less than 1% were from Midwest Capital.

THE BUSINESS OF MIDAMERICAN ENERGY

OVERVIEW OF MIDAMERICAN ENERGY'S BUSINESS

Currently, most of MidAmerican Energy's business is conducted in a rate-regulated environment and accordingly, many of its decisions as to the source and use of resources and other strategic matters are evaluated from a utility business perspective. However, beginning January 1, 1998, MidAmerican Energy began managing its operations as four distinct business units:
generation, transmission, energy delivery and retail. Under this corporate framework, MidAmerican Energy believes that its preparations for, and opportunities to succeed in, the future electric and gas energy environment will be enhanced. With the establishment of these four business units, MidAmerican Energy believes that it is able to focus on the specific needs and anticipated risks and opportunities of its major business units in a more flexible manner. Some administrative functions are handled by a corporate services group which supports all of the business units.

54

Although specific functions may be moved between business units as future circumstances warrant, the principal focus of each business unit has been established:

[] Generation--Significant functions of the generation business unit include the production and purchase of energy and the sale of wholesale energy.

[] Transmission--The transmission business unit coordinates all activities related to MidAmerican Energy's transmission facilities, including monitoring access to and assuring the reliability of the transmission system.

[] Energy Delivery--Energy delivery includes the distribution of electricity and natural gas to end-users, and related activities.

[] Retail--Retail includes marketing, customer service and related functions for core and complementary products and services.

ELECTRICITY AND GAS DISTRIBUTION AND SALES

MidAmerican Energy distributes electricity in Council Bluffs, Des Moines, Fort Dodge, Iowa City, Sioux City and Waterloo, Iowa, the Quad Cities (Davenport and Bettendorf, Iowa and Rock Island, Moline and East Moline, Illinois) and a number of adjacent communities and areas. MidAmerican Energy distributes natural gas in Cedar Rapids, Des Moines, Fort Dodge, Iowa City, Sioux City and Waterloo, Iowa, the Quad Cities, Sioux Falls, South Dakota, and a number of adjacent communities and areas. As of September 30, 1999, MidAmerican Energy had approximately 655,100 retail electric customers and 627,700 retail natural gas customers.

In addition to retail sales, MidAmerican Energy delivers electricity to other utilities and municipalities who distribute it to end-use customers. These sales are referred to as sales for resale. MidAmerican Energy also transports natural gas, for a fee, through its distribution system for certain large customers who have independently secured their own supply of natural gas.

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

MidAmerican Energy has a residential, agricultural, commercial and diversified industrial customer group in which no single industry or customer accounted for more than 3% (food and kindred products industry) of its total 1998 electric operating revenues or 3% (food and kindred products industry) of its total 1998 gas operating margin. Among the primary industries served by MidAmerican Energy are those which are concerned with the manufacturing, processing and fabrication of primary metals, real estate, food products, farm and other non-electrical machinery, and cement and gypsum products.

For the year ended December 31, 1998, MidAmerican Energy derived approximately 69% of its gross operating revenues from its regulated electric business and 25% from its regulated gas business. For 1997 and 1996, the corresponding percentages were 65% electric and 31% gas, and 66% electric and 32% gas, respectively.

In an Iowa pricing settlement approved in 1997 by the Iowa Utilities Board, MidAmerican Energy was given permission to negotiate individual contracts with its industrial and commercial electric customers. The negotiated contracts have differing terms and conditions as well as prices. The contracts range in length from five to ten years, and some have price renegotiation and early termination provisions exercisable by either party. A vast majority of the contracts are for terms of seven years or less, although some large customers have agreed to 10-year contracts. Prices are set as fixed prices; however, many contracts allow for potential price adjustments with respect to environmental costs, government imposed public purpose programs, tax changes and transition costs. While the contract prices are fixed (except for the potential adjustment elements), the costs MidAmerican Energy incurs to fulfill these contracts will vary. MidAmerican Energy presently intends to manage this risk through hedging and other similar arrangements. On an aggregate basis, the annual revenues under these contracts are approximately $180,000,000.

In addition, MidAmerican Energy is precluded by the 1997 settlement agreement from filing for an increase in its Iowa electric rates prior to 2001, unless its annual return on common equity falls below 9%. Likewise, the other parties to the agreement, including the Office of the Consumer Advocate, are prohibited from seeking a reduction in MidAmerican Energy's electric rates prior to 2001, unless the return on common equity, adjusted for the equal sharing between shareholders and customers of earnings above a 12% return on common equity, exceeds 14%.

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 1998, 40% of MidAmerican Energy's electric revenues were reported in the months of June, July, August and September, reflecting the use of electricity for cooling, and 54% of MidAmerican Energy's gas revenues were reported in the months of January, February, March and December, reflecting the use of gas for heating.

MIDAMERICAN ENERGY'S ELECTRIC SYSTEM

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 1999, MidAmerican Energy recorded an hourly peak demand of 3,833 megawatts, which is 190 megawatts more than MidAmerican Energy's previous record hourly peak of 3,643 megawatts set in 1998.

MidAmerican Energy's accredited 1998 summer net generating capability was 4,425 megawatts. Accredited net generating capability represents the amount of MidAmerican Energy-owned generation or generation under power purchase contracts available to meet the requirements on MidAmerican Energy's electric system, net of the effect of participation purchases and sales. The net generating capability at any time may be lower 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 is interconnected with Iowa utilities and utilities in neighboring utilities and is involved in an electric power pooling agreement known as MAPP. MAPP is a voluntary association of electric utilities doing business in Iowa, Minnesota, Nebraska and North Dakota and portions of Montana, South Dakota and Wisconsin and the Canadian provinces of Saskatchewan and Manitoba. Its membership also includes power marketers, regulatory agencies and independent power producers. MAPP facilitates operation of the regional transmission system, serves as a power and energy market clearing house and is responsible for the safety and reliability of the bulk electric system.

Each MAPP participant is required to maintain for emergency purposes a net generating capability reserve of at least 15% above its system peak demand. If a participant's capability reserve falls below the 15% minimum, significant penalties could be contractually imposed by MAPP. MidAmerican's reserve margin for 1998 was approximately 20%.

LITIGATION

COOPER LITIGATION

On July 23, 1997, the Nebraska Public Power District (or 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 three issues under the parties' long-term power purchase agreement for the capacity and energy of MidAmerican Energy's Cooper Nuclear Station. More specifically, 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 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 contingent counterclaims. The contingent counterclaims filed by MidAmerican Energy are generally as follows:
(1) that MidAmerican has no duty under the power purchase agreement to reimburse or pay 50% of the decommissioning costs unless certain conditions occur; (2) that NPPD has the duty to repay all amounts that MidAmerican Energy has prefunded for decommissioning in the event NPPD operates the plant after the term of the power purchase agreement; (3) that NPPD is equitably estopped from continuing to operate the plant after the term of the power purchase agreement;
(4) that NPPD has granted MidAmerican Energy an option to continue taking 50% of the power from the plant; (5) that the term "monthly power costs" as defined in the power purchase agreement does not include costs and expenses associated with decommissioning the plant; (6) that MidAmerican Energy has no duty to pay for nuclear fuel, operation and maintenance projects or capital improvements that have useful lives after the term of the power purchase agreement; (7) that transition costs are not included in any decommissioning costs and expenses; (8) that NPPD has breached its duty to MidAmerican Energy in making investments of certain funds; (9) that reserves in certain accounts are excessive and should be refunded to MidAmerican Energy; and (10) that NPPD must credit MidAmerican Energy for certain payments by MidAmerican for low-level radioactive waste disposal.

On October 6, 1999, the Court rendered summary judgment for NPPD on the above-mentioned issue concerning liability for decommissioning (issue one in the first paragraph above) and the related contingent counterclaims filed by MidAmerican Energy (issues one, two, three and five in the second paragraph above). The Court referred all remaining issues in the case to mediation, and cancelled the November 1999 trial date. MidAmerican Energy plans to appeal the Court's summary judgment ruling and will participate in mediation in an attempt to resolve the remaining issues. MidAmerican Energy and NPPD are currently involved in discovery.

LITIGATION

NORTH STAR STEEL COMPANY

On December 8, 1997, North Star Steel Company, a MidAmerican Energy electric retail customer, filed a complaint in the United States District Court for the Southern District of Iowa naming MHC and MidAmerican Energy as defendants. The complaint alleged that MidAmerican Energy's refusal to allow North Star to obtain retail electric service from an unspecified alternative energy company amounted to a violation of federal antitrust laws. North Star sought to recover an unspecified

58

level of damages, and to require MidAmerican Energy to provide retail wheeling service so that North Star could obtain electricity from an unnamed supplier. On June 23, 1998, the District Court issued an Order Granting Summary Judgment in favor of MidAmerican Energy. On July 20, 1998, North Star appealed that decision to the United States Court of Appeals for the Eighth Circuit. On July 7, 1999, the United States Court of Appeals for the Eighth Circuit affirmed the District Court grant of summary judgment in favor of MidAmerican Energy. On October 5, 1999, North Star filed a petition for a writ of certiorari seeking to have the U.S. Supreme Court agree to review a decision by the 8th Circuit Court of Appeals which had upheld a ruling by the U.S. District Court for the Southern District of Iowa granting summary judgment in favor of MidAmerican Energy. In a related matter North Star unsuccessfully appealed to the Iowa District Court an Iowa Utilities Board declaratory ruling that was favorable to MidAmerican Energy.

DESCRIPTION OF THE SECURITIES

The Securities will be issued under and governed by an indenture, as supplemented by a First Supplemental Indenture, dated as of March 11, 1999, between the Company and Bank of New York, as trustee. The following summary of the material terms contained in the indenture and the Securities is subject to, and is qualified in its entirety by reference to, the Trust Indenture Act of 1939, and all the provisions of the indenture and the Securities, including the definitions of terms not defined in this prospectus. This summary does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines your rights as holders of these Securities. We have filed copies of the indenture and the registration rights agreement as exhibits to the registration statement that includes this prospectus.

The form and terms of the exchange Securities and the initial Securities are identical in all material respects, except that transfer restrictions and registration rights applicable to the initial Securities do not apply to the exchange Securities. The exchange Securities will evidence the same debt as the initial Securities and will be governed by the same indenture. Where we refer to "Securities" in this prospectus, we are referring to both initial Securities and exchange Securities.

As used in this description, the term "Company" refers only to MidAmerican Funding, LLC, and not to any of its subsidiaries or affiliates.

GENERAL

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

The 5.85% Senior Secured Notes due 2001 and 5.85% Senior Secured Exchange Notes due 2001 (collectively, the "2001 Notes") will be issued in the aggregate principal amount of $200 million. The 2001 Notes will mature, and shall be repaid at their principal amount, on March 1, 2001.

The 6.339% Senior Secured Notes due 2009 and 6.339% Senior Secured Exchange Notes due 2009 (collectively, the "2009 Notes") will be issued in the aggregate principal amount of $175 million. The 2009 Notes will mature, and shall be repaid at their principal amount, on March 1, 2009.

The 6.927% Senior Secured Bonds due 2029 and 6.927% Senior Secured Exchange Bonds due 2029 (collectively, the "Bonds") will be issued in the aggregate principal amount of $325 million. The Bonds will mature, and shall be repaid at their principal amount, on March 1, 2029.

Each Security will bear interest at the relevant rate per annum stated above from March 11, 1999, or from the most recent interest payment date to which interest has been paid or provided for. Interest on the Securities will be payable semiannually on March 1 and September 1 of each year, commencing September 1, 1999, to the holders of record at the close of business on the preceding February 15 and August 15, respectively, until the relevant principal amount has been paid or made available for payment. Interest on the Securities will be computed on the basis of a 360-day year of twelve 30-day months.

If neither the exchange offer is consummated nor a shelf registration with respect to the resale of the Securities is declared effective by December 7, 1999, the interest rate on each series of the Securities will increase by 0.5% from and including such date, until the consummation of an exchange offer or the effective date of a shelf registration statement. If the exchange offer is not consummated or the shelf registration statement is not declared effective by March 12, 2001, such increase in interest rates will become permanent.

63

Any 2001 Notes that remain outstanding after the consummation of the exchange offer, together with all 2001 Exchange Notes issued in connection with the exchange offer, will be treated as a single class of securities under the indenture. Any 2009 Notes that remain outstanding after the consummation of the exchange offer, together with all 2009 Exchange Notes issued in connection with the exchange offer, will be treated as a single class of securities under the indenture. Any Bonds that remain outstanding after the consummation of the exchange offer, together with all Exchange Bonds issued in connection with the exchange offer, will be treated as a single class of securities under the indenture.

RANKING

The Securities will be senior secured obligations of the Company ranking on an equal basis with all other existing and future senior obligations of the Company. The Securities will rank senior to all existing and future subordinated indebtedness of the Company. The Securities will effectively rank junior to all indebtedness and other liabilities, including preferred stock, of the Company's Subsidiaries, to the extent of the assets of such Subsidiaries. The indenture contains restrictions on the ability of the Company and MHC to incur additional indebtedness. The indenture contains no restrictions on the amount of additional unsecured indebtedness which the Company's Subsidiaries, other than MHC, may incur. In addition, the indenture permits each of the Company's Subsidiaries, other than MHC, to incur significant additional amounts of secured indebtedness.

Prior to the initial offering of the Securities in March 1999, the Company did not have any debt obligations. The Company conducts its operations predominantly through MHC, its wholly owned subsidiary, and substantially all of the Company's consolidated assets relating to operations are held by MHC and its Subsidiaries, including MidAmerican Energy. Because the Company is a holding company, its rights and the rights of its creditors, including Holders of the Securities, in respect of claims on the assets of each of the Company's Subsidiaries upon any liquidation or administration are structurally subordinated to, and therefore will be subject to the prior claims of, each such Subsidiary's preferred stockholders and creditors (including trade creditors of and holders of debt issued by such subsidiary), except to the extent that the Company may itself be a creditor with recognized claims against such Subsidiary. At September 30, 1999, MHC and its direct and indirect Subsidiaries had total indebtedness, including preferred stock, of approximately $1.316 million, all of which would be effectively senior to the Securities.

The ability of the Company to pay interest on the Securities is, to a large extent, dependent upon the receipt by it of dividends and other distributions from its direct and indirect Subsidiaries, and from MidAmerican Energy in particular. The Company believes that such payments, which will be funded by cash flows generated through MidAmerican Energy's operations, will be sufficient to enable the Company to meet all of its obligations as they become due, including the Company's obligations under the Securities. The availability of distributions from the Company's Subsidiaries is subject to the satisfaction of various covenants and conditions contained in the applicable Subsidiaries' existing and future financing documents and certain utility regulatory restrictions.

COLLATERAL

The Securities will be secured by a pledge of all of the capital stock of
MHC.

Unless there is an Event of Default, the Company will be able to vote, as it sees fit in its sole discretion, the pledged shares of capital stock.

If the Company meets the conditions to its defeasance option or its covenant defeasance option as described below under the caption "--Defeasance and Covenant Defeasance," or the indenture is otherwise discharged, the lien of the indenture on the pledged shares will terminate and the pledged shares will be released to the Company without any further action by the trustee or any other person.

The proceeds of any sale of the collateral securing the Securities (the "Collateral") following an Event of Default might not be sufficient to satisfy the payments due on the Securities. If an Event of Default occurs under the

64

indenture, the trustee, on behalf of the holders of the Securities, in addition to any rights or remedies available to it under the indenture, may take such action as it deems advisable to protect and enforce its right in the Collateral, including the institution of foreclosure proceedings. The proceeds received by the trustee from any foreclosure will be applied by the trustee, first, to pay the expenses of such foreclosure and fees and other amounts then payable to the trustee under the indenture and, second, to pay the Securities.

COVENANTS

Except as otherwise described under "--Defeasance and Covenant Defeasance" below, for so long as any Securities remain outstanding or any amount remains unpaid on any of the Securities, the Company will comply with the terms of the covenants described below.

PAYMENT OF PRINCIPAL AND INTEREST

The Company will duly and punctually pay the principal of and interest on the Securities in accordance with the terms of the Securities and the indenture.

MAINTENANCE OF OFFICE OR AGENCY

The Company will maintain in the Borough of Manhattan, The City of New York, (1) an office or agency of a paying agent where the Securities may be paid and notices and demands to or upon the Company in respect of the Securities and the indenture may be served and (2) an office or agency of a registrar where Securities may be surrendered for registration of transfer and exchange. 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 fails to maintain any required office or agency or fails to furnish the trustee with the address of that office or agency, all presentations, surrenders, notices and demands may be served at the office of the trustee.

AVAILABLE INFORMATION

Notwithstanding that the Company may not be required to be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, from and after the date of effectiveness of the registration statement required to be filed by the registration rights agreement, the Company will file or cause to be filed with the SEC and provide the trustee with the information, documents and other reports, or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe, with respect to the Company specified in Sections 13 and 15(d) of the Exchange Act. If the Company is subject to the reporting requirements of Sections 13 or 15(d) of the Exchange Act, it will also provide such information, documents or reports to the Holders of the Securities. Prior to the effective date of that registration statement, the Company shall provide, upon written request of the Holders of the Securities or prospective Holders of the Securities who are qualified institutional buyers and are designated by existing Holders, with a copy to the trustee, such information with respect to the Company as is required by Rule 144A to enable resales of the Securities to be made pursuant to Rule 144A. The Company also will comply with the other provisions of Section 314(a) of the Trust Indenture Act.

CONSOLIDATION, MERGER, CONVEYANCE, SALE OR LEASE

The Company may not consolidate with or merge with or into any other Person, or convey, transfer or lease its consolidated properties and assets substantially as an entirety, in one transaction or in a series of related transactions, to any Person, or permit any Person to merge into or consolidate with the Company, unless:

(1) (x) the Company will be the surviving or continuing Person or (y) if other than the Company, the surviving or continuing Person or purchaser or lessee will be 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 expressly assumes by supplemental indenture the Company's obligations under the Securities and the indenture;

65

(2) immediately after giving effect to such transaction, no Event of Default shall have occurred and be continuing; and

(3) the Company or such other surviving or continuing Person, as applicable, shall continue to have a valid, perfected, first priority interest in the Collateral.

LIMITATION ON DISTRIBUTIONS

The indenture provides that the Company shall only declare, recommend, make or pay any Distribution to any of its shareholders if there exists no Event of Default and no Event of Default will result from making that Distribution, and either:

(1) at the time and as a result of that Distribution, the Company's Leverage Ratio does not exceed 0.67:1 and the Company's Interest Coverage Ratio is not less than 2.2:1; or

(2) if it is not in compliance with the foregoing ratios, at such time its senior secured long term debt rating is at least BBB, or its then equivalent, with S&P and DCR and Baa2, or its then equivalent, with Moody's.

This "Limitation on Distributions" covenant will cease to be in effect if the Rating Agencies confirm in writing that, without this covenant, the Company's senior secured long term debt would still be rated at least BBB+, or its then equivalent, from each of S&P and DCR and Baa1, or its then equivalent, from Moody's. If the restriction on Distributions ceases to be in effect, the Company will be under no obligation to reinstate such restriction or otherwise observe its terms if such ratings are thereafter lowered or withdrawn.

In order to obtain the release of the restriction on Distributions, the Company shall deliver to the trustee written confirmation from each Rating Agency of the ratings conditions described in the preceding paragraph.

LIMITATION ON INDEBTEDNESS OF THE COMPANY AND OF MHC

The indenture provides that the Company will not incur any Indebtedness other than (1) as part of the Company's permitted businesses and activities described under "--Limitation on Business Activities" below and (2) other Indebtedness incurred subsequent to receipt of written confirmation from the Rating Agencies that such incurrence would not result in a Ratings Downgrade.

The indenture further provides that the Company will not permit MHC to incur any Indebtedness other than Indebtedness outstanding on the date of original issue of the Securities under MHC's agreements then in existence and extensions of such Indebtedness.

LIMITATION ON LIENS

The indenture permits the Company to incur certain unsecured indebtedness and does not in any way restrict or prevent any Subsidiary other than MHC from incurring unsecured indebtedness. With respect to secured indebtedness, however, the indenture provides that neither the Company nor any Significant Subsidiary will issue, assume or guarantee any Indebtedness secured by a Lien upon any property or assets (other than cash or cash equivalents) of the Company or such Significant Subsidiary, as applicable, without effectively providing that the outstanding Securities (together with, if the Company so determines, any other indebtedness or obligation then existing or thereafter created ranking equally with the Securities) shall be secured equally and ratably with (or prior to) such Indebtedness so long as such Indebtedness shall be so secured. The foregoing restriction on Liens will not, however, apply to the following "Permitted Liens":

(1) Liens in existence on the date of original issue of the Securities;

66

(2) any Lien created or arising over any property which is acquired, constructed or created by the Company or any of its Significant Subsidiaries, but only if (A) such Lien secures only principal amounts (not exceeding the cost of such acquisition, construction or creation) raised for the purposes of such acquisition, construction or creation, together with any costs, expenses, interest and fees incurred in relation thereto or a guarantee given in respect thereof, (B) such Lien is created or arises on or before 180 days after the completion of such acquisition, construction or creation and (C) such Lien is confined solely to the property so acquired, constructed or created;

(3) any Lien securing amounts not more than 180 days overdue or otherwise being contested in good faith;

(d) any Lien upon specific items of inventory or other goods and proceeds of the Company and/or a Significant Subsidiary securing obligations of the Company and/or a Significant Subsidiary in respect of bankers' acceptances issued or created for the account of such person to facilitate the purchase, shipment or storage of such inventory or other goods;

(b) any Lien on any property or assets existing at the time of acquisition thereof and which is not created in anticipation of such acquisition, unless such Lien was created to secure or provide for the payment of any part of the purchase price of such property or assets; and

(c) any Lien created or outstanding on or over any asset of any company which becomes a Significant Subsidiary on or after the date of the issuance of the Securities where such Lien is created before the date on which such company becomes a Significant Subsidiary;

(7) (a) Liens required by any contract, statute or regulation in order to permit the Company or a Significant Subsidiary to perform any contract or subcontract made by it with or at the request of a governmental entity or any department, agency or instrumentality thereof, or to secure partial, progress, advance or any other payments by the Company or a Significant Subsidiary to such governmental unit pursuant to the provisions of any contract, statute or regulation;

(b) any Lien securing industrial revenue, development, pollution control or similar bonds issued by or for the benefit of the Company or a Significant Subsidiary, provided that such industrial revenue, development, pollution control or similar bonds do not provide recourse generally to the Company and/or such Significant Subsidiary; and

(8) (a) any Lien which arises pursuant to any order of attachment, distraint or similar legal process arising in connection with court proceedings and any Lien which secures the reimbursement obligation for any bond obtained in connection with an appeal taken in any court proceeding, so long as the execution or other enforcement of such Lien arising pursuant to such legal process is effectively stayed and the claims secured thereby are being contested in good faith and, if appropriate, by appropriate legal proceedings, and any Lien in favor of a plaintiff or defendant in any action before a court or tribunal as security for costs and/or expenses; and

(b) any Lien arising by operation of law or by order of a court or tribunal or any lien arising by an agreement of similar effect, including, without limitation, judgment Liens;

(9) any extension, renewal or replacement (or successive extensions, renewals or replacements), as a whole or in part, of any Liens referred to in the foregoing clauses, for amounts not exceeding the principal amount of the Indebtedness secured by the Lien so extended, renewed or replaced, provided that such extension, renewal or replacement Lien is limited to all or a part of the same property or assets that were covered by the Lien extended, renewed or replaced (plus improvements on such property or assets);

(10) any Lien created in connection with Project Finance Debt;

(11) any Lien created by MidAmerican Energy that is then permitted to be created under the terms of its then existing mortgages and indentures on the terms in effect at the time of creation of the Lien;

(12) any Lien created in connection with the securitization of some or all of the assets of MidAmerican Energy and the associated issuance of Indebtedness as authorized by applicable state or federal law in connection with the restructuring of jurisdictional electric or gas businesses; and

68

(13) any Lien on stock created in connection with a mandatorily convertible or exchangeable stock or debt financing, provided that any such financing may not be secured by or otherwise involve the creation of a Lien on any capital stock of MHC or MidAmerican Energy or any successor thereto.

Notwithstanding the foregoing, the Company and/or a Significant Subsidiary may create Liens over any of their respective properties or assets so long as the aggregate amount of Indebtedness secured by all such Liens, excluding the amount of Indebtedness secured by Liens described in clauses (1) through (13) above, does not exceed 10% of Consolidated Net Tangible Assets in the aggregate calculated as of the date of creation of such Liens, based upon the Consolidated Net Tangible Assets appearing on the most recently available balance sheet for the most recently concluded calendar quarter.

LIMITATION ON BUSINESS ACTIVITIES

The indenture provides that the Company will not enter into any business operations other than:

(1) the transactions contemplated by the indenture, the Escrow Agreement, the registration rights agreement and the Merger Agreement,

(2) activities related to the acquisition, management and ownership of MHC,

(3) entering into and performing any agreements to accomplish the foregoing and

(4) exercising any corporate powers that are incidental to or necessary, suitable or convenient for the accomplishment of the foregoing;

provided, that the Company may enter into additional business operations from time to time in the future if, prior to doing so, it obtains written confirmation from the Rating Agencies that the entering into of such new businesses will not result in a Ratings Downgrade.

The indenture further provides that the Company will cause its Significant Subsidiaries to engage only in:

(1) those types of businesses and other activities in which the Company or MHC or any of its direct or indirect subsidiaries or controlled partnerships or joint ventures (collectively, "MidAmerican Group") are engaged in on the date of original issuance of the Securities, including, without limitation, any geographic or other expansion of such businesses or activities, and

(2) any other business or activity which is deemed necessary, useful or desirable in connection with such existing businesses and activities or any such permitted additional geographic or other expansions of such businesses and activities.

OPERATIONAL COVENANTS

The indenture contains additional affirmative covenants (which are collectively referred to in this prospectus as the "Operational Covenants") requiring the Company and its Significant Subsidiaries to:

(1) comply with specified Project Documents (as defined in the indenture) and maintain all utility facilities that are operated by the Company or any Significant Subsidiary in accordance with reasonably prudent utility practices;

(2) obtain and maintain necessary governmental approvals and other approvals and consents required in connection with all utility facilities which are operated by the Company or any Significant Subsidiaries for so long as such facilities remain in operation;

69

(3) preserve and maintain good title or valid leasehold rights in the real property owned or leased by them from time to time and the personal property owned by them from time to time, subject to Permitted Liens;

(4) comply with all applicable laws and governmental approvals;

(5) obtain and maintain customary insurance, subject to reasonable availability and costs;

(6) pay and discharge all material taxes, assessments, charges and claims, other than those which are the subject of a good faith contest and for which adequate reserves have been established; and

(7) if a casualty or condemnation shall occur in respect of facilities which are operated and controlled by the Company or its Significant Subsidiaries, diligently pursue all rights to compensation;

in each case subject to an exception for any noncompliance or other failure that would not reasonably be expected to have a material adverse effect on the ability of the Company to perform its regularly scheduled payment obligations under the Securities. The Operational Covenants will no longer be applicable to the Securities, and the failure to comply with such covenants, restrictions and other provisions will no longer constitute a default or an Event of Default under the indenture, following the first date upon which:

(1) MidAmerican Holdings' senior secured long term debt securities (the "Reference Securities") are rated Baa3 or better by Moody's and BBB- or better by each of S&P and DCR (or, in any case, if such person ceases to rate such Reference Securities for reasons outside the control of the Company, the equivalent investment grade credit rating from any other "nationally recognized statistical rating organization," within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Securities Exchange Act of 1934, selected by the Company as a replacement rating agency), and provided no Event of Default or event which with notice or passage of time would constitute an Event of Default shall exist on such date, and

(2) MidAmerican Holdings has redeemed, repurchased or defeased, by way of covenant defeasance or other defeasance, all of its 9-1/2% Senior Notes due 2006 issued pursuant to the terms of the indenture, dated as of September 20, 1996, between MidAmerican Holdings and IBJ Schroder Bank & Trust Company.

MODIFICATION OF THE INDENTURE

The indenture contains provisions permitting the Company and the trustee to modify the indenture or any supplemental indenture or the rights of the Holders of Securities of each series to be affected with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of each series to be affected, subject to the same conditions described below under "--Modification or Waiver of Certain Covenants."

The indenture also contains provisions permitting the Company and the trustee to amend the indenture by entering into one or more supplemental indentures in certain circumstances without the consent of the Holders of any Securities:

(1) to cure any ambiguity,

(2) to correct or supplement any provision in the indenture which may be defective or inconsistent with any other provision in the indenture,

(3) to evidence the merger of the Company or the replacement of the trustee and

(4) to make any other changes that do not materially adversely affect the rights of any Holders of Securities.

70

EVENTS OF DEFAULT

An Event of Default with respect to the Securities is defined in the indenture as:

(1) default for 30 days in the payment of any interest on the Securities;

(2) default for three days in the payment of principal of or any premium on the Securities at maturity, upon redemption, upon required purchase, upon acceleration or otherwise;

(3) material default in the performance, or breach, of any material covenant or obligation of the Company in the indenture (which shall not include, among other things, the Operational Covenants) and continuance of such material default or breach for a period of 90 days after written notice specifying such default 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 of the Securities;

(4) default in the performance, or breach, of any of the Operational Covenants (if then effective) which would reasonably be expected to result in a material adverse effect on the financial condition of the Company and its Subsidiaries, taken as a whole, and continuance of such default or breach for a period of 90 days after written notice specifying such default 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 of the Securities, subject to various cure and ratings confirmation exceptions in the case of defaults involving the Project Document covenants;

(5) the trustee fails to have a perfected security interest in the pledged capital stock of MHC for a period of 10 days;

(6) default in the payment of the principal of any bond, debenture, note or other evidence of indebtedness, in each case for money borrowed, or in the payment of principal under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for Borrowed Money, of the Company or any Significant Subsidiary if such Indebtedness for Borrowed Money is not Project Finance Debt and provides for recourse generally to the Company, which default for payment of principal is in an aggregate principal amount exceeding $75,000,000 when such indebtedness becomes due and payable, whether at maturity, upon redemption or acceleration or otherwise, if such default shall continue unremedied or unwaived for more than 30 Business Days and the time for payment of such amount has not been expressly extended, until such time as such payment default is remedied, cured or waived; and

(7) the failure of the Company or a Significant Subsidiary generally to pay its debts as they become due, or the admission in writing of its inability to pay its debts generally, or the making of a general assignment for the benefit of its creditors, or the institution of any proceeding by or against the Company or a Significant Subsidiary (other than any such proceeding brought against the Company or a Significant Subsidiary that is dismissed within 180 days from the commencement thereof) seeking to adjudicate it bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition (in each case, other than a solvent liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition) of it or its debts under any law relating to bankruptcy, insolvency, reorganization, moratorium or relief of debtors, or seeking the entry of an order for relief or appointment of an administrator, receiver, trustee, intervenor or other similar official for it or for any substantial part of its property, or the taking of any action by the Company or a Significant Subsidiary to authorize or consent to any of the actions described in this subparagraph (7).

The Company will give the trustee notice by facsimile or other written communication satisfactory to the trustee of any Event of Default within five days after the occurrence of that Event of Default becoming known to the Company, and of the measures it is taking to remedy that Event of Default.

71

If an Event of Default with respect to the Securities shall occur and be continuing, either the trustee or (x) in the case of an Event of Default described under clause (1) or (2) under "Events of Default" above, the Holders of at least 33% in aggregate principal amount of the Securities, or (y) in the case of any other Event of Default, the Holders of a majority in aggregate principal amount of the Securities, may declare the principal amount of the Securities, and any interest accrued thereon, to be due and payable immediately. At any time after such declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained, if all Events of Default 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 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.

No Holder of the Securities of a series shall have any 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 under the indenture, unless:

(a) such Holder has previously given written notice to the trustee 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 shall have made written request to the trustee to institute proceedings in respect of such Event of Default in its own name as trustee;

(c) such Holder or Holders 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, 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 that 90-day period by the Holders of a majority in principal amount of the outstanding Securities.

As noted above, actions to be taken by the Holders of the Securities with respect to an Event of Default, including giving notice to the Company and the trustee of an Event of Default, declaring an acceleration of the Securities, rescinding a declaration of acceleration, exercising remedies with respect to the Collateral and instituting and controlling proceedings following an Event of Default, may be taken by the holders of the specified percentages of the aggregate principal amount of Securities outstanding. For purposes of voting on modifications to the indenture or supplemental indentures or the rights of Holders of the Securities, the consent of a majority in aggregate principal amount of the outstanding Securities of each series to be affected is required. For these purposes, each of the 2001 Notes, the 2009 Notes and the Bonds will be treated as a separate series of Securities under the indenture. However, as a result of voting together as one class with respect to matters involving an Event of Default, holders of one or two series of the Securities will likely be able to control the actions taken with respect to an Event of Default without obtaining the consent of holders of the other series of Securities.

OPTIONAL REDEMPTION

GENERAL

The Securities of each series will be 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 Securities being redeemed; or

72

(2) the sum of the present values of the remaining scheduled payments of principal of and interest on the series of Securities 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, in the case of the 2001 Notes, the Treasury Yield plus 15 basis points, in the case of the 2009 Notes and the Treasury Yield plus 25 basis points, in the case of the Bonds,

plus, for (1) or (2) above, whichever is applicable, accrued interest on such Securities 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 Securities are to be redeemed, selection of Securities 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 Redemption Date, the Securities or portions of Securities called for redemption will cease to bear interest, and the holders of those Securities will have no right in respect of those Securities 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 Security (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 Security 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 Security, the Redemption Price of such Security 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 Security, the Redemption Price of such Security will be such greater amount (redemption at a premium). In no event may a Security 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 Security 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 Security 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 0 basis points (in the case of the 2001 Notes), 15 basis points (in the case of the 2009 Notes) and 25 basis points (in the case of the Bonds), 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 Security to be redeemed optionally will or will not exceed 100% of its principal amount and, accordingly, whether such Security 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 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.

73

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 Security. 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 Security. 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 Security proposed to be redeemed is less than its principal amount, such Security may only be redeemed at par.

DEFEASANCE AND COVENANT DEFEASANCE

The Company, at its option, may elect (a) to be discharged from any and all obligations in respect of a series of Securities ("Defeasance") (except in each case for the obligations to, among other things, register the transfer or exchange of such Securities, replace stolen, lost or mutilated Securities, maintain paying agencies, hold moneys for payment in trust and pay when due all principal and interest solely out of moneys held in trust) or (b) not to comply with certain covenants ("Covenant Defeasance") of the indenture with respect to a series of Securities described above under "Consolidation, Merger, Conveyance, Sale or Lease," "Limitation on Distributions", "Limitation on Indebtedness of the Company and MHC", "Limitation on Liens", "Limitation on Business Activities" and "Operational Covenants"; if, in either case, the Company irrevocably deposits with the trustee, as trust funds in trust specifically pledged as security for, and dedicated solely to, the benefit of the Holder or Holders of such Securities of such series, (1) money or (2) U.S. Government Obligations which through the payment of interest and principal in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money, or (3) a combination thereof, in each case in an amount sufficient, in the opinion of a nationally recognized firm of independent accountants, to pay and discharge the principal of and premium and interest on the outstanding Securities of such series on the dates such payments are due in accordance with the terms of the Securities of such series, or if the Company has designated a Redemption Date pursuant to the next paragraph, to and including the Redemption Date so designated by the Company. Other conditions precedent to effecting Defeasance or Covenant Defeasance include:

(1) that the Securities will not be delisted by any securities exchange on which they are then traded as a result of the deposit of trust funds in trust;

(2) no Event of Default or event which with notice or lapse of time would become an Event of Default (including by reason of such deposit) with respect to the Securities of such series shall have occurred and be continuing on the date of such deposit; and

(3) such Defeasance or Covenant Defeasance shall not result in the breach or violation of, or constitute a default under, any other material agreement or instrument by which the Company is bound.

To exercise any such option, the Company is required to deliver to the trustee:

(a) an opinion of independent counsel of recognized standing to the effect that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit, which in the case of Defeasance must be based on a change in law or a ruling by the U.S. Internal Revenue Service, and

(b) an officer's certificate as to compliance with all conditions precedent provided for in the indenture relating to the satisfaction and discharge of the Securities of such series.

74

If the Company wishes to deposit or cause to be deposited money or U.S. Government Obligations to pay or discharge the principal of and interest, if any, on the outstanding Securities of a series to and including a Redemption Date on which all of the outstanding Securities of such series are to be redeemed, such Redemption Date shall be irrevocably designated by a board resolution delivered to the trustee on or before the date of deposit of such money or U.S. Government Obligations, and such board resolution shall be accompanied by an irrevocable Company request that the trustee give notice of such redemption in the name and at the expense of the Company not less than 30 nor more than 60 days prior to such Redemption Date in accordance with the indenture.

If the trustee or the paying agent is unable to apply any moneys deposited in trust to effect a Defeasance or Covenant Defeasance by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then any obligations from which the Company had been discharged or released shall be revived and reinstated as though no such deposit of moneys in trust had occurred, until such time as the trustee or paying agent is permitted so to apply all of such moneys deposited in trust.

MODIFICATION OR WAIVER OF CERTAIN COVENANTS

The Company may omit in any particular instance to comply with any term, provision or condition in the indenture with respect to the Securities of a series if before the time for such compliance the Holders of at least a majority in aggregate principal amount of the outstanding Securities of that series shall, by act of such Holders, either modify the covenant or waive such compliance in such instance or generally waive compliance with such term, provision or condition; provided that no such modification shall, without the consent of each Holder of Securities of that series:

(1) change the stated maturity upon which the principal of or the interest on the Securities of that series is due and payable;

(2) reduce the principal amount or redemption price of the Securities of that series or the rate of interest on the Securities of that series;

(3) change any place of payment or the currency in which the Securities of that series or any premium or the interest on the Securities of that series is payable;

(4) impair the right to institute suit for the enforcement of any such payment on or after the stated maturity of those Securities (or, in the case of redemption, on or after the Redemption Date for those Securities); or

(5) reduce the percentage in principal amount of the outstanding Securities of that series, the consent of Holders of which is required for any waiver of compliance with certain provisions of the indenture or certain defaults under the indenture and their consequences provided for in the indenture.

The Securities owned by the Company or any of its affiliates shall be deemed not to be outstanding for, among other purposes, consenting to any such modification.

TRANSFER

The Securities will be issued in registered form and will be transferable only upon the surrender of the Securities being transferred for registration of transfer. The Company may require payment of a sum sufficient to cover any tax, assessment or other governmental charge payable in connection with certain transfers and exchanges. See "--Book-Entry, Delivery and Form."

75

CONCERNING THE TRUSTEE

The Bank of New York, as successor to IBJ Whitehall Bank & Trust Company, is the trustee under the indenture and has been appointed by the Company as registrar and paying agent with respect to the Securities.

GOVERNING LAW

The indenture and the Securities will be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

BOOK-ENTRY, DELIVERY AND FORM

GENERAL

Except as described below, the Securities will be issued in the form of one or more fully registered Securities in global form ("Global Notes"). The Global Notes will be deposited with, or on behalf of, The Depository Trust Company (the "Depositary") and registered in the name of the Depositary or its nominee. Securities sold to "institutional accredited investors," as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act, will be delivered as definitive fully registered certificates.

Upon issuance of the Global Notes, the Depositary or its nominee will credit, on its book-entry registration and transfer system, the principal amount of Securities sold to qualified institutional buyers pursuant to Rule 144A represented by such Global Notes to the account of institutions that have accounts with the Depositary or its nominee participants (the "DTC Participants") and Euroclear will credit on its book-entry registration and transfer system the number of Securities sold to certain persons in offshore transactions in reliance on Regulation S under the Securities Act also represented by Global Notes to the account of institutions that have accounts with Euroclear or its nominee participants (the "Euroclear Participants" and, collectively with the DTC Participants, the "Participants"). Ownership of beneficial interests in the Global Notes will be limited to Participants or persons that may hold interests through Participants. Ownership of beneficial interests in the Global Notes will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depositary or its nominee (with respect to the Participants' interests) for such Global Notes, or by Participants or persons that hold interests through Participants (with respect to beneficial interests of persons other than Participants). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of those securities in definitive form. Such laws may impair the ability to transfer or pledge beneficial interests in the Global Notes.

So long as the Depositary or its nominee is the registered holder of any Global Notes, the Depositary or its nominee, as the case may be, will be considered the sole legal owner of such Securities for all purposes under the indenture and the Securities. Except as described below, owners of beneficial interests in Global Notes will not be entitled to have those Global Notes registered in their names, will not receive or be entitled to receive physical delivery in exchange for those Global Notes and will not be considered to be the owners or holders of those Global Notes for any purpose under the indenture or the Securities. The Company understands that under existing industry practice, if an owner of a beneficial interest in a Global Note desires to take any action that the Depositary, as the holder of that Global Note, is entitled to take, the Depositary would authorize the Participants to take such action, and that the Participants would authorize beneficial owners owning through such Participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

The Company will make available to the trustee by the applicable interest payment date or maturity date any payment of principal or interest due on the Securities. As soon as practicable thereafter, the trustee will make such payments to the Depositary or its nominee, as the case may be, as the registered owner of the Global Notes representing such Securities in accordance with existing arrangements between the trustee and the Depositary.

76

The Company expects that the Depositary or its nominee, upon receipt of any payment of principal or interest in respect of the Global Notes, will credit immediately the accounts of the related Participants with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Note as shown on the records of the Depositary. The Company also expects that payments by Participants to owners of beneficial interests in the Global Notes held through such Participants will be governed by standing instructions and customary practices, as is now 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 Participants.

None of the Company, the trustee, or any payment agent for the Global Notes will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any of the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for other aspects of the relationship between the Depositary and its Participants or the relationship between such Participants and the owners of beneficial interests in the Global Notes owning through such Participants.

Unless and until exchanged in whole or in part for Securities in definitive form in accordance with the terms of the Securities, 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 of any such nominee to a successor of the Depositary or a nominee of each successor.

Although the Depositary has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among Participants of the Depositary, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the trustee nor the Company will have any responsibility for the performance by the Depositary or its Participants or indirect Participants of their respective obligations under the rules and procedures governing their operations. The Company and the trustee may conclusively rely on, and shall be protected in relying on, instructions from the Depositary for all purposes.

CERTIFICATED NOTES

Securities that are originally issued to institutional "accredited investors" who are not qualified institutional buyers will be issued in certificated form.

The Global Notes shall be exchangeable for corresponding certificated Securities registered in the name of persons other than the Depositary or its nominee only if:

(1) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for any of the Global Notes or at any time ceases to be a clearing agency registered under the Exchange Act;

(2) there shall have occurred and be continuing an Event of Default with respect to the applicable Securities; or

(3) the Company executes and delivers to the trustee, an order that the Global Notes shall be so exchangeable.

Any certificated Securities will be issued only in fully registered form, and shall be issued without coupons in denominations of $1,000 and integral multiples of $1,000. Any certificated Securities issued will be registered in the names and in the denominations requested by the Depositary.

THE CLEARING SYSTEM

The Depositary has advised the Company as follows: The Depositary is limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing

77

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 was created to hold securities of institutions that have accounts with the Depositary and to facilitate the clearance and settlement of securities transactions among it Participants in such securities through electronic book-entry changes in accounts of Participants, thereby eliminating the need for physical movement of securities certificates. The Depositary's Participants include securities brokers and dealers, bank, trust companies, clearing corporations and certain other organizations. Access to the Depositary's book-entry system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, whether directly or indirectly.

CERTAIN DEFINITIONS

The following is a summary of some of the defined terms used in the indenture. We refer you to the indenture for the full definition of all these terms, as well as any other terms used in this prospectus for which no definition is provided.

"Capitalized Lease Obligations" means all lease obligations of the Company and its Subsidiaries which, under GAAP, are or will be required to be capitalized, in each case taken at the amount thereof accounted for as indebtedness in conformity with such principles.

"Comparable Treasury Issue" means, in the case of the 2001 Notes, the 2009 Notes and the Bonds, the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of such Securities 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.

"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 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.

"Consolidated Current Liabilities" means the consolidated current liabilities of the Company and its Subsidiaries, but excluding the current portion of long term Indebtedness which would otherwise be included therein, as determined on a consolidated basis in accordance with GAAP.

PLAN OF DISTRIBUTION

Each broker-dealer that receives exchange Securities for its own account as a result of market-making activities or other trading activities in connection with the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the exchange Securities. This prospectus, as it may be amended or supplemented from time to time, may be used by participating broker-dealers during the period referred to below in connection with resales of exchange Securities received in exchange for initial Securities if the initial Securities were acquired by the participating broker-dealers for their own accounts as a result of their market-making or other trading activities. We have agreed that this prospectus, as it may be amended or supplemented from time to time, may be used by a participating broker-dealer in connection with resales of exchange Securities for a period ending 120 days after the registration statement of which this prospectus is a part has been declared effective (subject to extension) or, if earlier, when all exchange Securities have been disposed of by the participating broker-dealer.

We will not receive any proceeds from the issuance of the exchange Securities offered by this prospectus. Exchange Securities received by broker-dealers for their own accounts in connection with 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 these methods of resale, at market prices prevailing at the time of resale, at prices related to prevailing market prices or at negotiated prices. Any resale may be made directly to purchasers or to or through brokers or dealers and/or the purchasers of any exchange Securities. Any broker-dealer that resells exchange Securities that were received by it for its own account in connection with the exchange offer and any broker-dealer that participates in a distribution of exchange Securities may be deemed to be an "underwriter" within the meaning of the Securities Act, and any profit on any resale of exchange Securities and any commissions or concessions received by any of those 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 a "underwriter" within the meaning of the Securities Act.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
FOR UNITED STATES HOLDERS

The following discussion is the opinion of Latham & Watkins, our counsel, as to the material federal income tax consequences expected to result to you if you exchange your initial Securities for exchange Securities in the exchange offer. This opinion is based on:

[] the facts described in the registration statement of which this prospectus is a part;

[] the Internal Revenue Code of 1986, as amended;

[] current, temporary and proposed treasury regulations promulgated under the Internal Revenue Code;

[] the legislative history of the Internal Revenue Code;

[] current administrative interpretations and practices of the Internal Revenue Service; and

[] court decisions.

all as of the date of this prospectus. In addition, the administrative interpretations and practices of the Internal Revenue Service include its practices and policies as expressed in private letter rulings that are not binding on the Internal Revenue Service, except with respect to the particular taxpayers who requested and received those rulings. Future legislation, treasury regulations, administrative interpretations and practices and/or court decisions may adversely affect, perhaps retroactively, the tax considerations contained in this discussion. Any change could apply retroactively to transactions preceding the date of the change. The tax considerations contained in this discussion may be challenged by the Internal Revenue Service and may not be sustained by a court if challenged by the Internal Revenue Service, and we have not requested, and do not plan to request, any rulings from the Internal Revenue Service concerning the tax treatment of the exchange of initial Securities for exchange Securities.

Certain holders may be subject to special rules not discussed below, including, without limitation:

[] insurance companies;

[] financial institutions or broker-dealers;

[] tax-exempt organizations;

[] stockholders holding securities as part of a conversion transaction, or a hedge or hedging transaction or as a position in a straddle for tax purposes;

[] foreign corporations or partnerships; and

[] persons who are not citizens or residents of the United States.

YOU SHOULD CONSULT YOUR TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF EXCHANGING INITIAL SECURITIES FOR EXCHANGE SECURITIES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS.

The exchange of initial Securities for exchange Securities will be treated as a "non-event" for federal income tax purposes, because the exchange Securities will not be considered to differ materially in kind or extent from the initial Securities. Therefore, no material federal income tax consequences will result to you from exchanging initial Securities for exchange Securities.

MHC INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

(a) COMPANY STRUCTURE:

MHC Inc. (Company or MHC), formerly known as MidAmerican Energy Holdings Company, is a holding company for MidAmerican Energy Company (MidAmerican), MidAmerican Capital Company (MidAmerican Capital), Midwest Capital Group, Inc. (Midwest Capital) and MidAmerican Realty Services Company (MidAmerican Realty). Effective March 12, 1999, MHC is a wholly owned subsidiary of MidAmerican Funding LLC, which in turn is a wholly owned subsidiary of MidAmerican Energy Holdings Company, formerly known as CalEnergy Company, Inc. Prior to December 1, 1996, MidAmerican held the capital stock of MidAmerican Capital and Midwest Capital. Effective December 1, 1996, each share of MidAmerican common stock was exchanged for one share of Holdings common stock. As part of the transaction, MidAmerican distributed the capital stock of MidAmerican Capital and Midwest Capital to Holdings.

(b) CONSOLIDATION POLICY AND PREPARATION OF FINANCIAL STATEMENTS:

The accompanying Consolidated Financial Statements include the Company and its subsidiaries. For 1998, certain nonregulated operations of MidAmerican, which were previously included in Other, Net in the income statements, are presented in nonregulated operations lines. Prior year amounts have been reclassified accordingly. Amounts related to MidAmerican Realty are reflected as discontinued operations. (Refer to Note 25). All significant intercompany transactions have been eliminated.

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

(c) REGULATION:

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

Statement of Financial Accounting Standards (SFAS) No. 71 sets forth accounting principles for operations that are regulated and meet certain criteria. For operations that meet the criteria, SFAS 71 allows, among other things, the deferral of costs that would otherwise be expensed when incurred. A possible consequence of the changes in the utility industry is the discontinued applicability of SFAS 71. The majority of MidAmerican's electric and gas utility operations currently meet the criteria of SFAS 71, but its applicability is periodically reexamined. On December 16, 1997, MidAmerican's generation operations serving Illinois were no longer subject to the provisions of SFAS 71 due to passage of industry restructuring legislation in Illinois. Thus, in 1997, MidAmerican was required to write off the regulatory assets and liabilities from its balance sheet related to its Illinois generation operations. The net amount of such write-offs was not material. If other portions of its utility operations no longer meet the criteria of SFAS 71, MidAmerican 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. The following regulatory assets, primarily included in Other Assets in the Consolidated Balance Sheets, represent probable future revenue to MidAmerican because these costs are expected to be recovered in charges to utility customers (in thousands):

(d) REVENUE RECOGNITION:

Revenues are recorded as services are rendered to customers. MidAmerican records unbilled revenues, and related energy costs, representing the estimated amount customers will be billed for services rendered between the meter-reading dates in a particular month and the end of such month. Accrued unbilled revenues were $79.8 million and $80.2 million at December 31, 1998 and 1997, respectively, and are included in Receivables on the Consolidated Balance Sheets.

MidAmerican's Illinois and South Dakota jurisdictional sales, or approximately 12% of total retail electric sales, and the majority of its total retail gas sales are subject to adjustment clauses. These clauses allow MidAmerican to adjust the amounts charged for electric and gas service as the costs of gas, fuel for generation or purchased power change. The costs recovered in revenues through use of the adjustment clauses are charged to expense in the same period.

(e) DEPRECIATION AND AMORTIZATION:

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

                                         1998         1997         1996
                                         ----         ----         ----
Electric..........................       3.9%         3.8%         3.8%
Gas...............................       3.4%         3.4%         3.7%

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

The cost of repairs and minor replacements is charged to maintenance expense. Property additions and major property replacements are charged to plant accounts. The cost of depreciable units of utility plant retired or disposed of in the normal course of business is eliminated from the utility plant accounts and such cost, plus net removal cost, is charged to accumulated depreciation. An allowance for the estimated annual decommissioning costs of the Quad Cities Nuclear Power Station (Quad Cities Station) equal to the level of funding is included in depreciation expense. See Note 4(e) for additional information regarding decommissioning costs.

(f) INVESTMENTS AND NONREGULATED PROPERTY, NET:

Investments, managed primarily through the Company's nonregulated subsidiaries, and nonregulated property, net include the following amounts as of December 31 (in thousands):

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

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

(g) CONSOLIDATED STATEMENTS OF CASH FLOWS:

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

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

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

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 term of the NPPD contract. Beginning July 11, 1997, the Iowa portion of capital improvement costs is recovered currently from customers and is expensed as incurred. MidAmerican began charging the remaining Cooper capital improvement costs to expense as incurred in January 1997.

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

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

(i) ACCOUNTING FOR DERIVATIVES:

1) Preferred Stock Hedge Instruments:

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

The preferred stocks are publicly traded securities and, as such, changes in their fair value are reported, net of income taxes, as a part of Accumulated Other Comprehensive Income, Net in shareholders' equity. Unrealized gains and losses on the associated put options are included in the determination of the fair value of the preferred stocks. The fair value of the put options, including unrealized gains and losses, included in the determination of the fair value of the preferred securities as of December 31, 1998 and 1997, was $2.9 million and $1.9 million, respectively. Realized gains and losses on the put options are included in Realized Gains and Losses on Securities, Net in the Consolidated

F-11

Statements of Income in the period the underlying hedged fixed rate preferred stocks are sold. At December 31, 1998, the Company held put options with a notional value of $89.1 million.

2) Gas Futures Contracts and Swaps:

The Company uses gas futures contracts and swap contracts to reduce the volatility in the price of natural gas purchased to meet the needs of its customers. Investments in natural gas futures contracts, which total $0.3 million and $1.6 million as of December 31, 1998 and 1997, respectively, are included in Receivables on the Consolidated Balance Sheets. Gains and losses on gas futures contracts that qualify for hedge accounting are deferred and reflected as adjustments to the carrying value of the hedged item or included in Other Assets on the Consolidated Balance Sheets until the underlying physical transaction is recorded if the instrument is used to hedge an anticipated future transaction. The net gain or loss on gas futures contracts is included in the determination of income in the same period as the expense for the physical delivery of the natural gas. Realized gains and losses on gas futures contracts and the net amounts exchanged or accrued under the natural gas swap contracts are included in Cost of Gas Sold or Nonregulated Costs of Sales consistent with the expense for the physical commodity. Deferred net gains (losses) related to the Company's gas futures contracts are $(1.9) million and $(0.4) million as of December 31, 1998 and 1997, respectively.

The Company periodically evaluates the effectiveness of its natural gas hedging programs. If a high degree of correlation between prices for the hedging instruments and prices for the physical delivery is not achieved, the contracts are recorded at fair value and the gains or losses are included in the determination of income. At December 31, 1998, the Company held the following hedging instruments:

                                                                        Weighted Average

         Weighted average fixed price.........                               $2.098

3) New Accounting Pronouncement:

In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," which established accounting and reporting standards for derivative instruments and for hedging activities. SFAS 133 is effective for the Company on January 1, 2000. SFAS 133 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 certain conditions are met, such 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. An entity that elects to apply hedge accounting is required to establish at the inception of the hedge the method it will use in assessing the effectiveness of the derivative. The Company is in the process of evaluating the impact of this accounting pronouncement.

Goodwill is amortized using the straight-line method. Amortization expense included in the Company's Consolidated Statements of Income totaled $1.5 million, $1.4 million and $1.1 million for 1998, 1997 and 1996, respectively. The weighted average remaining life of goodwill as of December 31, 1998, is 18 years.

(k) DETAIL OF OTHER COMPREHENSIVE INCOME - INCOME TAXES:

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

                                                            1998          1997            1996

(2) LONG-TERM DEBT:

The Company's sinking fund requirements and maturities of long-term debt for 1999 through 2003 are $106 million, $134 million, $125 million, $25 million and $105 million, respectively.

MidAmerican's Variable Rate Pollution Control Revenue Obligations bear interest at rates that are periodically established through remarketing of the bonds in the short-term tax-exempt market. MidAmerican, at its option, may change the mode of interest calculation for these bonds by selecting from among several alternative floating or fixed rate modes. The interest rate shown in the Consolidated Statements of Capitalization is the weighted average interest rate as of December 31, 1998 and 1997. MidAmerican maintains dedicated revolving credit facility agreements or renewable lines of credit to provide liquidity for holders of these issues.

F-13

Substantially all of the former Iowa-Illinois Gas and Electric Company, a predecessor company, utility property and franchises, and substantially all of the former Midwest Power Systems Inc., a predecessor company, electric utility property in Iowa, or approximately 80% of gross utility plant, is pledged to secure mortgage bonds.

(3) JOINTLY OWNED UTILITY PLANT:

Under joint plant ownership agreements with other utilities, MidAmerican had undivided interests at December 31, 1998, in jointly owned generating plants as shown in the table below.

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

(4) COMMITMENTS AND CONTINGENCIES:

(a) CAPITAL EXPENDITURES:

Utility construction expenditures for 1999 are estimated to be $194 million, including $9 million for Quad Cities Station nuclear fuel. Nonregulated capital expenditures depend upon the availability of investment opportunities and other factors. During 1999, such expenditures are estimated to be approximately $9 million.

(b) MANUFACTURED GAS PLANT FACILITIES:

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

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

F-14

MidAmerican's estimate of probable remediation costs for the sites discussed above as of December 31, 1998, was $24 million. This estimate has been recorded as a liability and a regulatory asset for future recovery. The ICC has approved the use of a tariff rider which permits recovery of the actual costs of litigation, investigation and remediation relating to former MGP sites. MidAmerican's present rates in Iowa provide for a fixed annual recovery of MGP costs. MidAmerican intends to pursue recovery of the remediation costs from other PRPs and its insurance carriers.

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

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

(c) CLEAN AIR ACT:

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

On July 18, 1997, the EPA adopted revisions to the National Ambient Air Quality Standards (NAAQS) for ozone and a new standard for fine particulate matter. Based on data to be obtained from monitors located throughout each state, the EPA will determine which states have areas that do not meet the air quality standards (i.e., areas that are classified as nonattainment). If a state has area(s) classified as nonattainment area(s), the state is required to submit a State Implementation Plan specifying how it will reach attainment of the standards through emission reductions or other means. In August 1998, the Iowa Environmental Protection Commission adopted by reference the NAAQS for ozone and fine particulate matter.

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

(d) LONG-TERM POWER PURCHASE CONTRACT:

Payments to NPPD cover one-half of the fixed and operating costs of Cooper (excluding depreciation but including debt service) and MidAmerican's share of nuclear fuel cost (including nuclear fuel disposal) based on energy delivered. The debt service portion is approximately $1.5 million per month for 1999 and is not contingent upon the plant being in service. In addition, MidAmerican pays one-half of NPPD's decommissioning funding related to Cooper.

The debt amortization and Department of Energy (DOE) enrichment plant decontamination and decommissioning component of MidAmerican's payments to NPPD were $14.4 million, $13.8 million and $14.5 million and the net interest component was $2.9 million, $3.8 million and $3.6 million each for the years 1998, 1997 and 1996, respectively.

MidAmerican's payments for the debt principal portion of the power purchase contract obligation and the DOE enrichment plant decontamination and decommissioning payments are $15.0 million, $15.8 million, $16.6 million, $17.4 million and $18.3 million for 1999 through 2003, respectively.

(e) DECOMMISSIONING COSTS:

Based on site-specific decommissioning studies that include decontamination, dismantling, site restoration and dry fuel storage cost, MidAmerican's share of expected decommissioning costs for Cooper and Quad Cities Station, in 1998 dollars, is $256 million and $242 million, respectively. In Illinois, nuclear decommissioning costs are included in customer billings through a mechanism that permits annual adjustments. Such costs are reflected as base rates in Iowa tariffs.

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

As of December 31, 1998, MidAmerican's share of funds set aside by NPPD in internal and external accounts for decommissioning was $97.5 million. In addition, the funding plan also assumes various funds and reserves currently held to satisfy NPPD bond resolution requirements will be available for plant decommissioning costs after the bonds are retired in early 2004. The funding schedule assumes a long-term return on funds in the trust of 6.75% annually. Certain funds will be required to be invested on a short-term basis when decommissioning begins and are assumed to earn at a rate of 4.0% annually. NPPD is recognizing decommissioning costs over the life of the power sales contract. MidAmerican makes payments to NPPD related to decommissioning Cooper. These payments are included in MidAmerican's power purchase costs. The Cooper decommissioning component of MidAmerican's payments to NPPD was $7.9 million, $11.3 million and $9.9 million for the years 1998, 1997, and 1996, respectively, and is included in Other Operating Expenses in the Consolidated Statements of Income. Earnings from the internal and external trust funds, which are recognized by NPPD as the owner of the plant, are tax exempt and serve to reduce future funding requirements.

External trusts have been established for the investment of funds for decommissioning the Quad Cities Station. The total accrued balance as of December 31, 1998, was $117.0 million and is included in Other Liabilities and a like amount is reflected in Investments and represents the fair value of the assets held in the trusts.

MidAmerican's provision for depreciation included costs for Quad Cities Station nuclear decommissioning of $11.4 million, $9.8 million and $8.6 million for 1998, 1997 and 1996, respectively. The provision charged to expense is equal to the funding that is being collected in rates. The decommissioning funding component of MidAmerican's Illinois and Iowa tariffs assumes decommissioning costs, related to the Quad Cities Station, will escalate at an annual rate of 4.9% and the assumed annual return on funds in the trust is 6.9%. Earnings, net of investment fees, on the assets in the trust fund were $1.7 million, $4.5 million and $3.2 million for 1998, 1997 and 1996, respectively. See Note (14) for information regarding unrealized gains and losses.

F-16

(f) NUCLEAR INSURANCE:

MidAmerican 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 Commonwealth Edison (ComEd, the joint owner and operator of Quad Cities Station), insurance purchased directly by MidAmerican, 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 ComEd 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 that 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's aggregate maximum potential share of such 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, ComEd purchases primary and excess property insurance protection for the combined interests in Quad Cities, with coverage limits totaling $2.1 billion. For Cooper, MidAmerican 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 and NPPD are covered for their respective 50% obligation in the event of a loss totaling up to $2.75 billion. MidAmerican 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, and the property coverages purchased by ComEd, which includes the interests of MidAmerican, 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 from industry mutual policies for its obligations associated with Cooper and Quad Cities Station combined, total $11.2 million.

The master nuclear worker liability coverage, which is purchased by NPPD and ComEd 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 of workers in nuclear-related industries as a result of radiation exposure.

(g) COAL AND NATURAL GAS CONTRACT COMMITMENTS:

MidAmerican has entered into supply and related transportation contracts for its fossil fueled generating stations. The contracts, with expiration dates ranging from 1999 to 2003, require minimum payments of $110.2 million, $75.8 million, $28.0 million, $8.1 million and $2.6 million for the years 1999 through 2003, respectively. The Company expects to supplement these coal contracts with spot market purchases to fulfill its future fossil fuel needs.

MidAmerican has entered into various natural gas supply and transportation contracts for its utility operations. The minimum commitments under these contracts are $57.4 million, $40.1 million, $33.3 million, $18.7 million and $13.7 million for the years 1999 through 2003, respectively, and $60.7 million for the total of the years thereafter.

(h) OPERATING LEASE COMMITMENTS:

The Company has entered into various operating lease agreements covering facilities, computer and transportation equipment. Rental payments on operating leases were $23.7 million for 1998, $20.8 million for 1997, and $21.3 million for 1996. The approximate future minimum annual commitments under all operating leases are $13.6

F-17

million, $12.0 million, $7.4 million, $5.7 million and $3.9 million for the years 1999 through 2003, respectively, and $9.7 million for the total of the years thereafter.

(6) RETIREMENT PLANS:

The Company has primarily noncontributory defined benefit pension plans covering substantially all employees. Benefits under the plans are based on participants' compensation, years of service and age at retirement. Funding is based upon the actuarially determined costs of the plans and the requirements of the Internal Revenue Code and the Employee Retirement Income Security Act. MidAmerican has been allowed to recover funding contributions in rates.

The Company currently provides certain health care and life insurance (postretirement) benefits for retired employees. Under the plans, substantially all of the Company's employees may become eligible for these benefits if they reach retirement age while working for the Company. However, the Company retains the right to change these benefits anytime at its discretion. MidAmerican expenses postretirement benefit costs on an accrual basis and includes provisions for such costs in rates.

The Company also maintains noncontributory, nonqualified supplemental executive retirement plans for active and retired participants.

Net periodic pension, supplemental retirement and postretirement benefit costs includes the following components for the years ended December 31 (in thousands):

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 assets as of December 31, 1998, the Company had Rabbi trusts which held corporate-owned life insurance 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 cash value of the life insurance policies was $27.2 million and $21.5 million at December 31, 1998 and 1997, respectively.

The projected benefit obligation and accumulated benefit obligation for the supplemental executive plans were $55.1 million and $49.9 million, respectively, as of December 31, 1998, and $48.6 million and $40.3 million, respectively, as of December 31, 1997.

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 the aforementioned plans to the net amounts recognized in the Company's Consolidated Balance Sheets as of December 31 (dollars in thousands):

                                                  --------------------------
                                                     1998          1997
                                                  ---------     ------------
Assumptions used were:
Discount rate......................................   6.75%        7.0%
Rate of increase in compensation levels............   5.0%         5.0%
Weighted average expected long-term
    rate of return on assets.......................   9.0%         9.0%

The postretirement plan was amended on January 1, 1999, increasing the retiree co-payment for prescription drugs. This decrease in benefit obligation is reflected for December 31, 1998.

For purposes of calculating the postretirement benefit obligation, it is assumed health care costs for covered individuals prior to age 65 will increase by 8.4% in 1999 and that the rate of increase thereafter will decline by 1.0% annually to an ultimate rate of 5.25% by the year 2003. For covered individuals age 65 and older, it is assumed health care costs will increase by 6.0% in 1999 and 5.5% in 2000.

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 1998 would increase by $2.4 million, and the postretirement benefit obligation at December 31, 1998, would increase by $18.3 million. If the assumed health care trend rates were to decrease by 1.0%, the total service and interest cost for 1998 would decrease by $1.9 million and the postretirement benefit obligation at December 31, 1998, would decrease by $15.3 million.

The Company sponsors defined contribution pension plans (401(k) plans) covering substantially all employees. The Company's contributions vary depending on the plan, but are based primarily on each participant's level of contribution and cannot exceed the maximum allowable for tax purposes. The Company's total contributions were $5.6 million, $4.6 million and $4.4 million for 1998, 1997 and 1996, respectively.

(7) STOCK-BASED COMPENSATION PLANS:

The Company has stock-based compensation arrangements for employees and directors as described below. The Company accounts for these plans under Accounting Principles Board Opinion No. 25 and the related interpretations. The total compensation cost recognized in income for stock-based compensation awards was $0.3 million, $1.3 million, and $0.6 million for 1998, 1997, and 1996, respectively. Had the Company used Statement of Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), pro-forma net income for common stock would be $130.9 million, $135.3 million, and $130.9 million, while earnings per share would be $1.39, $1.38, and $1.30 for the years ended 1998, 1997, and 1996 respectively.

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

F-20

Stock Options - Under the Plan, the Board of Directors granted options to purchase shares of the Company's common stock (the Options) at the fair market value of the shares on the date of the grant. The options granted in 1998 and 1997 vest over a 3-year period at a rate of 33.3% per year and options granted in 1995 and 1996 vest over a 4-year period at a rate of 25% per year. Under the plan, all options expire ten years after the date of grant. Stock option activity for 1998, 1997, and 1996 is summarized as follows:

                                                     1998                   1997                       1996

Performance Shares - Under the Plan, participants were granted contingent shares of MHC common stock. The shares are contingent upon the attainment of specified performance measures within a 3-year performance period. During the performance period, the participant is entitled to receive dividends and vote the stock. The stock is vested upon achievement of the performance measures. If the specified criteria is not met within the 3-year performance period, the shares are forfeited. The following table provides certain information regarding contingent performance incentive shares granted under the Plan:

(9) RATE MATTERS:

As a result of a negotiated settlement in Illinois, MidAmerican reduced its Illinois electric service rates by annual amounts of $13.1 million and $2.4 million, effective November 3, 1996, and June 1, 1997, respectively. MidAmerican implemented an additional $0.9 million annual rate reduction for its Illinois residential customers, effective August 1, 1998, in connection with Illinois' electric utility restructuring law.

On June 27, 1997, the IUB approved a March 1997 settlement agreement between MidAmerican, the Iowa Office of Consumer Advocate (OCA) and other parties. Four major components of the settlement and their status are as follows:

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

2) Prices for industrial customers were reduced by $6 million annually and prices for commercial customers were reduced by $4 million annually. MidAmerican was given permission to implement these reductions through a retail access pilot project, negotiated individual contracts and tariffed rate reductions. On January 1, 1999, MidAmerican reduced base rates for certain non-contract commercial customers by approximately $1.5 million annually, subject to IUB approval. Additionally, MidAmerican will make a one-time refund for reductions that were not in place by the June 1, 1998, deadline. The remainder of the commercial and industrial price reductions were achieved through negotiated contracts and a retail access pilot project.

The negotiated contracts have differing terms and conditions as well as prices. The contracts range in length from five to ten years, and some have price renegotiation and early termination provisions exercisable by either party. The vast majority of the contracts are for terms of seven years or less, although, some large customers have agreed to 10-year contracts. Prices are set as fixed prices; however, many contracts allow for potential price adjustments with respect to environmental costs, government imposed public purpose programs, tax changes, and transition costs. While the contract prices are fixed (except for the potential adjustment elements), the costs MidAmerican incurs to fulfill these contracts will vary. On an aggregate basis the annual revenues under contract are approximately $180 million.

3) The Iowa energy adjustment clause (EAC) was eliminated. Prior to July 11, 1997, MidAmerican collected fuel costs from Iowa customers on a current basis through the EAC, and thus, fuel costs had little impact on net income. Since then, base rates for Iowa customers include a factor for recovery of a representative level of fuel costs. If the actual per-unit fuel cost varies from that factor, pre-tax earnings are affected. The fuel cost factor was to be reviewed in February 1999 and adjusted prospectively if the actual 1998 fuel cost per unit varied by more than 15% above or below the factor included in base rates. Based on 1998 actual fuel costs, MidAmerican will reduce the fuel cost recovery factor in 1999 base rates. The estimated annual reduction in revenues associated with this adjustment is $1.1 million.

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

Under a restructuring law enacted in 1997, a similar sharing mechanism is in place for Illinois operations. Two-year average ROE's greater than a two-year average benchmark will trigger an equal sharing of earnings on the excess. The benchmark is a calculation of average 30-year Treasury Bond rates plus 5.5% for 1998 and 1999 and 6.5% for 2000 through 2004. The initial calculation, due March 31, 2000, will be based on 1998 and 1999 results.

(10) DISCONTINUED OPERATIONS:

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

Proceeds received from the disposition of the oil and gas subsidiary included $210 million in cash and 870,000 warrants, after a stock split in 1997, to purchase KCS common stock. The warrants were valued at $6 million. Proceeds received from the disposition of the subsidiary that operates a computerized information system for the exchange of power in the electric industry included an unsecured note receivable for $0.7 million and warrants to purchase twenty percent of the acquirer which have been valued at zero. Proceeds received from the disposition of the coal mining subsidiary settlement were $15 million.

On October 6, 1999, the Company distributed its holding in the capital stock of MidAmerican Realty to MidAmerican Energy Holdings Company. The operations are the result of several acquisitions beginning in May 1998. Refer to Note (22), "Acquisitions."

Revenues from discontinued activities, as well as the results of operations and the estimated loss on the disposal of discontinued operations for the years ended December 31 are as follows (in thousands):

(11) CONCENTRATION OF CREDIT RISK:

The Company's electric utility operations serve 565,000 customers in Iowa, 85,000 customers in western Illinois and 3,000 customers in southeastern South Dakota. The Company's gas utility operations serve 489,000 customers in Iowa, 65,000 customers in western Illinois, 64,000 customers in southeastern South Dakota and 4,000 customers in northeastern Nebraska. The largest communities served by the Company are the Iowa and Illinois Quad-Cities; Des Moines, Sioux City, Cedar Rapids, Waterloo, Iowa City and Council Bluffs, Iowa; and Sioux Falls, South Dakota. The Company's utility operations grant unsecured credit to customers, substantially all of whom are local businesses and residents. As of December 31, 1998, billed receivables from the Company's utility customers totaled $20.1 million.

F-24

As described in Note 18, billed receivables related to utility services have been sold to a wholly owned unconsolidated subsidiary.

MidAmerican Capital has investments in preferred stocks of companies in the utility industry. As of December 31, 1998, the total cost of these investments was $54 million. MidAmerican Capital has an investment in the common stock of McLeodUSA Incorporated, the total cost of which was $44 million at December 31, 1998.

MidAmerican Capital has entered into leveraged lease agreements with companies in the airline industry. As of December 31, 1998, the receivables under these agreements totaled $33 million.

(12) PREFERRED SHARES:

The $5.25 Series Preferred Shares, which were not redeemable prior to November 1, 1998, for any purpose, are subject to mandatory redemption on November 1, 2003 at $100 per share. The $7.80 Series Preferred Shares have sinking fund requirements under which 66,600 shares will be redeemed at $100 per share each May 1, beginning in 2001 through May 1, 2006.

The total outstanding cumulative preferred stock of MidAmerican not subject to mandatory redemption requirements may be redeemed at the option of the Company at prices which, in the aggregate, total $32.2 million. The aggregate total the holders of all preferred stock outstanding at December 31, 1998, are entitled to upon involuntary bankruptcy is $181.8 million plus accrued dividends. Annual dividend requirements for all preferred stock outstanding at December 31, 1998, total $12.9 million.

During 1996, MidAmerican redeemed all shares of the $1.7375 Series of preferred stock. The redemptions were made at a premium, which resulted in a charge to net income of $1.6 million.

(13) SEGMENT INFORMATION:

In 1998, the Company adopted SFAS 131, "Disclosures About Segments of an Enterprise and Related Information."

The Company has two reportable operating segments: electric and gas. The electric segment derives most of its revenue from retail sales of regulated electricity to residential, commercial and industrial customers, and sales to other utilities; whereas the gas segment derives most of its revenue from retail sales of regulated natural gas to residential, commercial and industrial customers. The gas segment also earns significant revenues by transporting gas owned by others through its distribution systems. Pricing for electric and gas sales are established separately by regulated agencies; therefore, management also reviews each segment separately to make decisions regarding allocation of resources and in evaluating performance. Common operating costs, interest income, interest expense, income tax expense, and equity in the net loss of investees are allocated to each segment.

The following tables provide certain Company information on an operating segment basis as of and for the years ended December 31 (in thousands):

Dividend income related to MHC common stock held by MidAmerican Capital of $0.5 and $0.4 million for 1998 and 1997, respectively, is included in Nonregulated and Other Net Income above but has been eliminated in Net Income in the Consolidated Statements of Income. In addition, a realized gain of $4.2 million from MidAmerican Capital's sale of such stock to MHC in 1998 has also been eliminated in Net Income in the Consolidated Statements of Income.

(14) FAIR VALUE OF FINANCIAL INSTRUMENTS:

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

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

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

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

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

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

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

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

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

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

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

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

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

(18) SALE OF ACCOUNTS RECEIVABLE:

In 1997 MidAmerican entered into a revolving agreement, which expires in 2002, to sell all of its right, title and interest in the majority of its billed accounts receivable to MidAmerican Energy Funding Corporation (Funding Corp.), a special purpose entity established to purchase accounts receivable from MidAmerican. Funding Corp. in turn has sold receivable interests to outside investors. In consideration of the sale, MidAmerican received $70 million in cash and the remaining balance in the form of a subordinated note from Funding Corp. In 1998, the revolving balance was reduced to $60 million due to a decline in accounts receivable available for sale. The agreement is structured as a true sale under which the creditors of Funding Corp. will be entitled to be satisfied out of the assets of Funding Corp. prior to any value being returned to MidAmerican or its creditors and, as such, the accounts receivable sold are not reflected on MHC's Consolidated Balance Sheets. At December 31, 1998, $97.4 million of accounts receivable, net of reserves, was sold under the agreement.

(22) ACQUISITIONS:

In 1998, the Company established MidAmerican Realty as a holding company for its real estate brokerage operations. The Company, through MidAmerican Realty, then acquired several real estate brokerage operations and related businesses.

The Company purchased all of the outstanding capital stock of the following companies: Iowa Realty Co. Inc., Edina Financial Services, Inc., Home Real Estate Company of Omaha and CBS Real Estate Company. Additionally, the Company purchased all assets of J.C. Nichols Residential, Inc. and Nebraska Land Title & Abstract Company. The aggregate cost of these acquisitions was $108 million.

F-34

Each acquisition was accounted for as a purchase business combination. All identifiable assets acquired and liabilities assumed were assigned a portion of the acquisition price equal to their fair value at the date of acquisition. The Company's Consolidated Income Statements reflect the results of operations of the acquired businesses from the date of their respective acquisition dates, which range from May 27, 1998, through September 1, 1998, except for a minor acquisition in December 1998.

As discussed in Note (10), the Company distributed its holding in the capital stock of MidAmerican Realty to MidAmerican Energy Holdings Company in October 1999 and has reflected these operations as discontinued operations.

(23) SUBSEQUENT EVENTS (UNAUDITED):

On August 11, 1998, a definitive merger agreement was entered into between the Company and CalEnergy Company, Inc. (CalEnergy), a global provider of energy services. On March 12, 1999, the merger transaction was completed, and the Company became an indirect wholly owned subsidiary of CalEnergy, which subsequently changed its name to MidAmerican Energy Holdings Company. In accordance with the merger agreement, each outstanding share of the Company's common stock was converted to the right to receive $27.15 in cash.

On October 25, 1999, an investor group including Berkshire Hathaway, Inc. (Berkshire) reached a definitive agreement to acquire the new MidAmerican Energy Holdings Company for $35.05 per share in cash, along with the assumption of debt. Berkshire will invest approximately $1.25 billion in common stock and a non-dividend-paying convertible preferred stock of the surviving corporation, giving Berkshire an approximate 75% interest in the Company's parent on a fully diluted basis. Berkshire will also invest $800 million in non-transferable trust preferred stock. The other investors, who in total will invest approximately $300 million are Walter Scott, former chairman of Peter Kiewit Sons' Inc. and a Board Member of the new MidAmerican Energy Holdings Company, and David L. Sokol, the Chairman and Chief Executive Officer of the same.

MIDAMERICAN FUNDING, LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A. GENERAL:

MidAmerican Funding, LLC (Company) is an Iowa limited liability company and a direct wholly owned subsidiary of MidAmerican Energy Holdings Company. The Company's direct wholly owned subsidiary is MHC Inc. (MHC), a public utility holding company. MHC's principal subsidiary is MidAmerican Energy Company (MidAmerican), a public utility with electric and natural gas operations.

The current corporate structure is the result of a merger transaction completed on March 12, 1999, involving MHC (formerly MidAmerican Energy Holdings Company) and CalEnergy Company, Inc. (CalEnergy). CalEnergy, through a reincorporation transaction, was renamed MidAmerican Energy Holdings Company (Holdings). Holdings is an exempt public utility holding company headquartered in Des Moines, Iowa.

In conjunction with the transaction, the Company paid $27.15 in cash for each outstanding share of MHC common stock for a total of approximately $2.42 billion in a merger pursuant to which MHC became a direct wholly owned subsidiary of the Company. The MidAmerican Merger has been accounted for as a purchase business combination and as such the results of operations of the Company include the results of MHC beginning March 12, 1999. The purchase price has been allocated to assets acquired and liabilities assumed based on preliminary valuations and the Company is awaiting final valuations. The Company recorded goodwill of approximately $1.5 billion which is being amortized using the straight line method over a 40 year period.

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

Unaudited pro forma consolidated revenue and net income of the Company and MHC for the nine months ended September 30, 1999 and 1998, as if the acquisition had occurred at the beginning of the year after giving effect to certain pro forma adjustments related to the acquisition, including the senior secured notes and bonds, were $1.34 billion and $142.9 million respectively, compared to $1.33 billion and $86.6 million respectively, for the same period last year.

The consolidated financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. In the opinion of the Company, all adjustments (consisting of normal recurring adjustments) have been made to present fairly the financial position, the results of operations and the changes in cash flows for the periods presented. The financial statements reflect operations of the Company's real estate brokerage subsidiary as discontinued operations. Refer to Note H for further information. Prior year amounts have been reclassified to a basis consistent with the current year presentation. All significant intercompany transactions have been eliminated. 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 audited consolidated financial statements of MHC and the notes thereto included elsewhere in this registration statement.

B. ENVIRONMENTAL MATTERS:

(1) MANUFACTURED GAS PLANT FACILITIES--

The United States Environmental Protection Agency (EPA) and the state environmental agencies have determined that contaminated wastes remaining at certain decommissioned manufactured gas

F-41

MIDAMERICAN FUNDING, LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

plant (MGP) facilities may pose a threat to the public health or the environment if such contaminants are in sufficient quantities and at such concentrations as to warrant remedial action.

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

MidAmerican's estimate of probable remediation costs for the sites discussed above as of September 30, 1999, was $21 million. This estimate has been recorded as a liability and a regulatory asset for future recovery. The Illinois Commerce Commission (ICC) has approved the use of a tariff rider which permits recovery of the actual costs of litigation, investigation and remediation relating to former MGP sites. MidAmerican's present rates in Iowa provide for a fixed annual recovery of MGP costs. MidAmerican intends to pursue recovery of the remediation costs from other PRPs and its insurance carriers.

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

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

(2) CLEAN AIR ACT--

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

On July 18, 1997, the EPA adopted revisions to the National Ambient Air Quality Standards (NAAQS) for ozone and a new standard for fine particulate matter. Based on data to be obtained from monitors located throughout each state, the EPA will determine which states have areas that do

MIDAMERICAN FUNDING, LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

not meet the air quality standards (i.e., areas that are classified as nonattainment). If a state has area(s) classified as nonattainment area(s), the state is required to submit a State Implementation Plan specifying how it will reach attainment of the standards through emission reductions or other means.

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

C. RATE MATTERS:

(1) ELECTRIC--

In Iowa on June 1, 1998, prices for electric residential customers were reduced by an amount which will have a $5.0 million annual impact on revenues. The decrease was the last of three for Iowa residential customers as a result of a 1997 settlement agreement.

Through several steps from mid-1997 to the end of 1998, electric prices for Iowa industrial customers were reduced by an amount which will have a $6 million annual impact on revenues, and electric prices for Iowa commercial customers were reduced by an amount which will have a $4 million annual impact on revenues. The reductions were achieved through a retail access pilot project, negotiated individual electric contracts and a $1.5 million tariffed rate reduction for certain non-contract commercial customers.

The negotiated electric contracts have differing terms and conditions as well as prices. The contracts range in length from five to ten years, and some have price renegotiation and early termination provisions exercisable by either party. The vast majority of the contracts are for terms of seven years or less, although, some large customers have agreed to ten-year contracts. Prices are set as fixed prices; however, many contracts allow for potential price adjustments with respect to environmental costs, government imposed public purpose programs, tax changes, and transition costs. While the contract prices are fixed (except for the potential adjustment elements), the costs MidAmerican incurs to fulfill these contracts will vary. On an aggregate basis the annual revenues under contract are approximately $180 million.

If MidAmerican's annual Iowa electric jurisdictional return on common equity (ROE) exceeds 12%, then earnings above the 12% level will be shared equally between customers and MidAmerican; if the ROE exceeds 14%, two-thirds of MidAmerican's share of those earnings above the 12% level will be used for accelerated recovery of certain regulatory assets. The 1997 pricing plan settlement agreement precludes MidAmerican from filing for increased rates prior to 2001 unless the ROE falls below 9%. Other parties signing the agreement are prohibited from filing for reduced rates prior to 2001 unless the ROE after reflecting credits to customers, exceeds 14%. On April 14, 1999, the Iowa Utilities Board (IUB) approved, subject to additional refund, MidAmerican's 1998 ROE calculation. During the second quarter of 1999, MidAmerican refunded $2.2 million to its Iowa non-contract customers related to the ROE calculation for 1998.

Under an Illinois restructuring law enacted in 1997, a similar sharing mechanism is in place for MidAmerican's Illinois electric operations. Two-year average ROEs greater than a two-year average benchmark will trigger an equal sharing of earnings on the excess. The benchmark is a calculation of average 30-year Treasury Bond rates plus 5.5% for 1998 and 1999. Legislation passed in July 1999 increases the benchmark for 2000 through 2004 to 8.5% above the 30-year Treasury bond rate. The initial calculation, which is still being defined and is due March 31, 2000, will be based on 1998 and 1999 results.

(2) GAS--

In October 1998, MidAmerican made a filing with the IUB requesting a rate increase for its Iowa retail gas customers. An interim rate increase of approximately $6.7 million annually was approved by the IUB on January 22, 1999, effective immediately. On April 23, 1999, the IUB issued an order approving a settlement agreement between MidAmerican, the Iowa Office of Consumer Advocate (OCA) and other parties which provides for an annual increase of $13.9 million. The new rates were implemented May 27, 1999.

In November 1998, MidAmerican filed with the South Dakota Public Utilities Commission (SDPUC) requesting a rate increase for its South Dakota retail gas customers. The SDPUC, on April 23, 1999, issued an order approving a rate increase of $2.4 million annually, effective May 1, 1999.

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

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

Statement of Financial Accounting Standards (SFAS) No. 71 sets forth accounting principles for operations that are regulated and meet certain criteria. For operations that meet the criteria, SFAS 71 allows, among other things, the deferral of costs that would otherwise be expensed when incurred. A possible consequence of the changes in the utility industry is the discontinued applicability of SFAS 71. The majority of MidAmerican's electric and gas utility operations currently meet the criteria of SFAS 71, but its applicability is periodically reexamined. On December 16, 1997, MidAmerican's generation operations serving Illinois were no longer subject to the provisions of SFAS 71 due to passage of industry restructuring legislation in Illinois. Thus in 1997, MidAmerican was required to write off the regulatory assets and liabilities from its balance sheet related to its Illinois generation operations. The net amount of such write-offs was not material. If other portions of its utility operations no longer meet the criteria of SFAS 71, MidAmerican 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.

E. MIDAMERICAN-OBLIGATED MANDATORILY REDEEMABLE PREFERRED SECURITIES:

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

F. SEGMENT INFORMATION:

The Company has two reportable operating segments: electric and gas. The electric segment derives most of its revenue from retail sales of regulated electricity to residential, commercial, and industrial customers and sales to other utilities; whereas the gas segment derives most of its revenue from retail sales of regulated natural gas to residential, commercial, and industrial customers. The gas segment also earns significant revenues by transporting gas owned by others through its distribution systems. Pricing for electric and gas sales are established separately by regulatory agencies; therefore, management also reviews each segment separately to make decisions regarding allocation of resources and to evaluate performance. Common operating costs are allocated to each segment.

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

Comprehensive income refers, in general, to changes in the Company's equity, except those resulting from transactions with shareholders. "Unrealized holding gains (losses)" reflects the overall increase (decrease) in the market value of marketable securities held by the Company as available-for-sale. The "reclassification adjustment" removes any gains (losses) that have been realized from sales of those securities and reflected in the Company's Net Income. The following table shows the income tax expense or benefit related to each component (in thousands):

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma condensed consolidated financial statements are based on the historical consolidated financial statements of MidAmerican Funding and MHC, combined and adjusted to give effect on a pro forma basis to the Offering and on a pro forma as adjusted basis to the Offering and the MidAmerican Merger and the transactions contemplated thereby, as described in the notes thereto. MidAmerican Funding had no results of operations prior to the Offering and the MidAmerican Merger. These statements should be read in conjunction with the historical financial statements and notes of MHC which are included and incorporated by reference in this registration statement. See "Incorporation by Reference."

The unaudited pro forma condensed consolidated statements of income for the year ended December 31, 1998, and for the nine months ended September 30, 1999, present the results of operations for MidAmerican Funding as if the Offering and the MidAmerican Merger had occurred at the beginning of the period presented. In addition, the statements of income do not reflect discontinued operations. A pro forma balance sheet is not required as of September 30, 1999, since both the Offering and the MidAmerican Merger are reflected in the historical balance sheet of MidAmerican Funding as of that date which is included elsewhere in this registration statement.

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

NOTES TO UNAUDITED PRO FORMA
CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Reflects the historical results of MidAmerican Funding subsequent to the MidAmerican Merger.

2. Reflects the historical results of MHC prior to the MidAmerican merger.

3. Immediately prior to the MidAmerican Merger, MidAmerican Funding issued $700 million of senior debt at a weighted average interest rate of 6.5%. The adjustments to interest on long-term debt are net of the amortization of related deferred debt issue costs and credits from a rate swap arrangement.

4. On March 12, 1999, MidAmerican Funding purchased MHC for $2,439.8 million, including transaction costs. The transaction was accounted for as a purchase business combination. The pro forma statements of income reflect amortization of balance sheet adjustments made to reflect the effect of the MidAmerican Merger on MHC's assets and liabilities. Adjustments made to the assets and liabilities were as follows (in thousands):

Goodwill ..............................................................    $1,477,440
Other current assets ..................................................       (16,674)
Power purchase contract ...............................................       (34,295)
Other non-current assets ..............................................      (217,340)
Other non-current liabilities .........................................       (61,034)
Long-term debt ........................................................        (5,782)
Deferred taxes ........................................................       120,038
MidAmerican-obligated preferred securities of subsidiary trust ........          (543)
                                                                           ----------
                                                                           $1,261,810
                                                                           ==========

A. The adjustment to power purchase contract was to reflect MHC's long-term power purchase contract at fair value based on the estimated market prices for similar purchases with similar remaining maturities.

B. The adjustment to other non-current assets was to reflect the fair value of MHC's investments in Quad Cities Nuclear Power Station, real estate and certain other investments.

C. The other non-current liabilities adjustment was to reflect MHC's compensation obligations and to reflect MHC's long-term fuel contracts at fair value based on the estimated market prices for similar purchases with similar remaining maturities.

D. Goodwill is amortized using the straight line method over 40 years and is reflected in nonregulated other operating expenses.

E. Other purchase accounting adjustments are being amortized using the straight line or other applicable method over the remaining estimated lives of the related assets and liabilities.

F. Income tax expense for the effects of the pro forma adjustments which affect taxable income is at an effective rate of 40%.

5. Other, net includes an adjustment to add back MHC merger transaction costs totaling $19.2 million for the nine months ended September 30, 1999, and $4.2 million for the year ended December 31, 1998.

ITEM 22. UNDERTAKINGS

The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

II-2


(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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;

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

The undersigned registrant hereby undertake 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.

The undersigned registrant hereby undertakes as follows: prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the application form.

The undersigned registrant hereby undertakes that every prospectus (i) that is filed pursuant to the immediately preceding paragraph or (ii) that purports to meet the requirements of Section l0(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment will be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time will 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 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 whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of the issue.

The undersigned registrant hereby undertakes to file an application of the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Securities and Exchange Commission under section 305(b)(2) of the Trust Indenture Act.

INDEMNIFICATION

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 manager, officer or employee, of the Company or is or was serving at the request of the Company as a director, manager, officer or employee of another corporation or of a partnership, limited liability

-6-

company, 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 manager, officer or employee or in any other capacity while serving as a manager, officer or employee, shall be indemnified and held harmless by the Company 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 Company to provide broader indemnification rights than the Act permitted the Company 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 Company expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that the payment of such expenses incurred by a manager, officer or employee in his or her capacity as a manager, officer or employee (and not in any other capacity in which service was or is rendered by such person while a manager, 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 Company of (i) a written undertaking, by or on behalf of such manager, officer or employee, to repay all amounts so advanced if it should be determined ultimately that such manager, 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 manager, 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 Company within thirty (30) days after a written claim has been received by the Company, the claimant may at any time thereafter bring suit against the Company 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 Company to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Company. The failure of the Company (including its Board of Managers, independent legal counsel or its members) 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. 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 Organization, operating agreement, agreement, vote of members or disinterested managers or otherwise.

-7-

E. The Company may maintain insurance, at its expense, to protect itself and any such manager, officer, employee or agent of the Company or another corporation, partnership, limited liability company, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Act.

ARTICLE X
AMENDMENTS

Subject to the last sentence of Section B of Article VIII, these Articles may be amended, repealed, changed or modified in accordance with the provisions of the Act and the Company's operating agreement. The foregoing notwithstanding, as long as any of the Securities are outstanding, (i) subject to clause (ii) below, the provisions of Article IV, V and Article VII of these Articles of Organization shall not be changed, amended, repealed or effected in any way unless the Company complies with the provisions of section (B)(x) of Article IV and (ii) paragraphs (B)(i), (ii) and (iv) of Article IV may be amended or modified if, prior to the effectiveness of such amendment or modification, the Company obtains written confirmation from each of Standard & Poor's Ratings Group, Moody's Investors Service, Inc. and Duff & Phelps Credit Rating Co. (or, if any such agency ceases to rate the Securities for any reason outside the control of the Company, any other "nationally recognized statistical rating organization" within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Securities Exchange Act of 1934, selected by the Company as a replacement rating agency; each a "Rating Agency"), that such amendment or modification will not result in lowering by any Rating Agency of the credit rating assigned to the Securities by such Rating Agency as of the date of such amendment or modification.

(f) In addition to the Managers, the Member shall have the right to attend any or all meetings of the Board of Managers, but shall have no right to participate in any vote of the Board of Managers. In addition, the Board of Managers may, by Majority Board Vote, invite any other Person to attend, as an observer, any meeting of the Board of Managers.

SECTION 3.6. ACTION BY WRITTEN CONSENT.

SECTION 3.7. TELEPHONIC MEETINGS. Managers shall have the right to participate in a meeting of the Board of Managers by means of conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting.

(a) The presence, in person, of a majority of the Managers comprising the Board of Managers, and for those actions of the Board of Managers taken pursuant to SECTION 3.1(C), the presence of a majority of the Board of Managers including the presence of the Independent Manager, shall constitute a quorum (a "QUORUM") for the transaction of business; provided that with respect to any regular meeting, notice thereof shall have been delivered to (or waived by) each Manager in accordance with SECTION 3.5(D).

(b) Each Manager shall have one vote and, except as required by SECTION 3.1(c), a Majority Board Vote shall be the act of the Board of Managers.

SECTION 3.9. MANAGEMENT RIGHTS. The Management of the Company rests exclusively with the Board of Managers, except as to duties granted to the Members of the Company pursuant to this SECTION 3.9. Notwithstanding anything herein to the contrary, to the extent that such actions are permitted by the Articles, the Company may not take any of the following actions without first obtaining the consent of the Member:

(a) the merger, consolidation or other reorganization of the Company;

(b) the liquidation, reorganization or recapitalization of the Company; or

(c) the issuance, repurchase or redemption of any Membership Interests or any rights to purchase Membership Interests.

In addition, the business and affairs of the Company shall be operated in such a manner as the Board of Managers deems reasonable and necessary or appropriate to preserve the limited liability of the managers, the separateness of the Company from the business of its members, and as long as the Securities are outstanding, the special purpose, bankruptcy remote status of the Company. To the extent permitted by law, as long as the Securities are outstanding, the Board of Managers shall make decisions with respect to the business and daily operations of the Company independent of, and not dictated by, any member or any affiliate of any member.

SECTION 3.10. INDEMNIFICATION. (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 or investigative, or arbitration and whether formal or informal ("PROCEEDING"), by reasons of the fact that he or she, or a person of whom he or she is the legal representative, is or was a manager or employee of the Company or is or was serving at the request of the Company as a manager or employee of another limited liability company or of a corporation, 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 manager or employee or in any other capacity while serving as a manager or employee (each, an "INDEMNIFIED PERSON"), shall be indemnified and held harmless by the Company 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 Company to provide broader indemnification rights than the permitted the Company 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 Company expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that the payment of such expenses incurred by a manager or employee in his or her capacity as a manager

-10-

or employee (and not in any other capacity in which service was or is rendered by such person while a manager 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 Company of (i) a written undertaking, by or on behalf of such manager or employee, to repay all amounts so advanced if it should be determined ultimately that such manager or employee is not entitled to be indemnified under this Section 3.10 or otherwise, or (ii) a written affirmation by or on behalf of such manager 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 clause (a) is not paid in full by the Company within thirty (30) days after a written claim has been received by the Company, the claimant may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim and, if successful, in whole or in part, the claimant shall be entitled to also be paid 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 Company to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Company. The failure of the Company (including its Board of Managers, independent legal counsel or its Members) 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 Section 3.10 shall not affect the validity or enforceability of any other provision of this Article III.

(d) Any action taken or omitted to be taken by any manager 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 Company 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.A.707 (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.

(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.A.707 (or any successor provision) of the Act.

-11-

(f) The rights conferred on any person by this Section 3.10 shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the this Agreement, vote of the Members or Independent Managers or otherwise.

(g) The Company may maintain insurance, at its expense, to protect itself and any such manager or employee of the Company or another limited liability company, corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Iowa Act.

(b) The proceeds of such liquidation shall be applied in the following order of priority: (i) first, to the expenses of such liquidation; (ii) second, to the debts and liabilities of the Company (including debts of the Company to the Member or its Affiliates and any fees and reimbursements payable under this Agreement), in the order of priority provided by law;
(iii) third, a reasonable reserve shall be set up to provide for any contingent or unforeseen liabilities or obligations of the Company to third parties (to be held and disbursed, at the discretion of the Member, by an escrow agent selected by the Member) and at the expiration of such period as the Member may deem advisable, the balance remaining in such reserve shall be distributed as provided herein; (iv) fourth, to the Member in accordance with SECTION 6.1.

(c) In connection with the liquidation of the Company, the Member shall have the first opportunity to make bids or tenders for all or any portion of the assets of the Company, and such assets shall not be sold to an outsider except only for a price higher than the highest and best bid of the Member.

SECTION 103. Form of Documents Delivered to Trustee

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Any certificate or instrument required to be given or executed by a Person which is not a natural person may be given or executed on behalf of such Person by any duly authorized designee of such Person.

Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

SECTION 104. Acts of Holders; Record Dates

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by the Holders of any

23

series of Securities may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by each such Holder in Person or by an agent duly appointed in writing, and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and 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 shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 104.

Without limiting the generality of the foregoing, unless otherwise established in or pursuant to a Board Resolution or set forth or determined in an Officers' Certificate, or established in one or more indentures supplemental hereto, in each case pursuant to Section 301, (i) a Holder of any Security may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by the Holder of any such Security,
(ii) a Holder of any such Security, including a Depositary that is a Holder of a Global Security, entitled hereunder to take any action hereunder with regard to such Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of the principal amount of such Security; and (iii) a Depositary that is a Holder of a Global Security may provide its proxy or proxies to the beneficial owners of interest in such Global Security through the Depositary's standing instructions and customary practices.

(b) The fact and date of the execution by any Person of any such instrument, writing or proxy 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, writing or proxy 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 of any such instrument, writing or proxy, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) The ownership of Securities shall be proved by the Security Register.

24

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security 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 Security.

(e) The Company may, in its discretion, by Board Resolution, set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, consent, waiver or Act provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series; provided that the Company shall have no obligation to set a record date; and provided further that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to any applicable Expiration Date (as defined below) by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect); provided, however, that no new record date may be established with the purpose or effect of rendering, and no other provision of this paragraph shall be construed to render, ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities entitled to join in the giving or making of
(i) any Notice of Default, (ii) any declaration of acceleration referred to in
Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512; provided that if the Trustee does not set any record

25

date within ten days after first receiving any such notice, declaration, rescission and annulment, request or direction, as the case may be, then the record date shall be the close of business on the date on which the Trustee first receives any such notice, declaration, rescission and annulment, request or direction, as the case may be. If any record date is set by the Trustee pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to any applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect); provided, however, that no new record date may be established with the purpose or effect of rendering, and no other provision of this paragraph shall be construed to render, ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken based on such record date previously set. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company's expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

With respect to any record date set pursuant to this Section 104(e), the party hereto which sets such record date may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other parties hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the earlier of (i) the existing Expiration Date and (ii) the proposed new Expiration Date. 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 105. Notices, Etc., to Trustee and Company

26

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 in writing and mailed, first-class, postage prepaid, to the Trustee at its Corporate Trust Office, 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 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.

SECTION 106. Notice to Holder; Waiver

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event at his address as it appears in the Security 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 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.

SECTION 111. Governing Law

THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

SECTION 112. Legal Holidays

SECTION 303. Execution, Authentication, Delivery and Dating

66

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 individual who was at any time the proper Officer of the Company shall bind the Company, notwithstanding that such individual 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 301 hereof, and a Company Order for the authentication 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 601 and 603) 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 201, 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 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall

67

not be necessary to deliver the documents otherwise required pursuant to Sections 201 and 301 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 310 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 304. Temporary Securities

Pending the preparation of definitive Securities of any series, the Company may execute, and upon compliance by the Company with Section 303, the Trustee or the Authenticating Agent shall authenticate and deliver, temporary Securities which are printed, 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

68

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 306 (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 304 or Section 305, 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 305. 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, transfers and exchanges 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 there-

69

for pursuant to Section 607. The Company may act as Security Exchange Agent/Registrar or Paying Agent.

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 304, 906 or 1107 not involving any transfer.

70

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 1104 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 305 are, with respect to any Global Security, subject to Section 307 hereof.

SECTION 306. 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 201 or as provided pursuant to Section 301, unless such restrictions on transfer shall be waived or modified, in accordance with applicable laws, by the written consent of the Company. Each of the Holder of each 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 313(b) (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.

71

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 or 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 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).

SECTION 307. Global Securities

(a) Form and Legend.

If the Company shall establish pursuant to Section 301 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 303, 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 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 202.

(b) Transfer and Exchange.

73

(i) Transfers of Global Notes as such. Except as otherwise expressly provided in this Indenture or any supplement thereto, 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 Globa1 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. 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

74

Global Security of such series be exchanged for one or more Definitive Securities (an "Optional Definitive Security Request"). 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 of 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 301, Definitive Securities issued in exchange for a Global Security pursuant to this Section 307(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.

83

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 (1) or (2) below:

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 (2).

(2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the re-

84

quirements 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 309, 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 310. 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 309) 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.

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 307(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 311. Cancellation

All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment 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 Securi-

85

ties so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 311, except as expressly permitted by this Indenture.

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 401 or 402 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 403 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.

108

and provides for recourse generally to the Company, or any Significant Subsidiary which default for payment of principal is in an aggregate principal amount exceeding $75,000,000 (or its equivalent in any other currency or currencies) when such indebtedness becomes due and payable at Maturity, if such default shall continue unremedied or unwaived for more than 30 Business Days and the time for payment of such amount has not been expressly extended; provided, however, that, subject to the provisions of Sections 601 and 602, the Trustee shall not be deemed to have knowledge of such default unless either (a) a Responsible Officer of the Trustee shall have actual knowledge of such default or (b) the Trustee shall have received written notice thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee under any such mortgage, indenture or other instrument; and provided further, that if such default under such indenture or instrument shall be remedied or cured by the Company or such Significant Subsidiary or waived by the holders of such indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been remedied, cured or waived without further action upon the part of the Trustee or any of the Holders; or

(9) any other Event of Default provided in the supplemental indenture or provided in or pursuant to the Board Resolution under which such series of Securities is issued or in the form of Security for such series.

110

SECTION 502. 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 (a) in the case of an Event of Default described under subparagraph (1) or (2) of Section 501 above, the Holders of at least 33% in aggregate principal amount of the Outstanding Securities, or (b) 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.

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 503.Collection of Indebtedness and Suits for Enforcement by Trustee

111

The Company covenants that if

(1) 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

(2) 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 and such default continues for a period of 3 days,

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 504. 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

112

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,

(i) 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

(ii) 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 607.

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 505. 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,

113

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 506. 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 607;

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 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 or any other Person lawfully entitled thereto.

SECTION 507. 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

(1) or (2) of Section 501 above, the Holders of at least 33% in aggregate principal amount of the Outstanding Securities, or (b) 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;

(3) 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;

(4) the Trustee for 90 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) 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 509. 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 510. 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 306, 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 511. 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 512. Control by Holders

116

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

(2) in respect of a covenant or provision hereof which under Article Nine 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 514. 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

(c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company.

123

If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days of such removal, the Trustee subject to such removal may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series, subject to Section 609.

(d) If at any time:

(1) the Trustee shall fail to comply with section 310(b) of the Trust Indenture Act pursuant to Section 608, with respect to any series of Securities to which the Trust Indenture Act may be applicable, after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2) the Trustee shall cease to be eligible under Section 609 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 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, (i) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (ii) subject to Section 514, 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.

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

124

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 611. 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

125

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 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 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 611, 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 612. 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 613. Preferential Collecting of Claims Against Company

126

(a) Subject to subsection (b) of this Section 613, 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 613, 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 613:

(1) 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 months' 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 (2) 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

(2) 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 months' period, or an amount equal to the 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:

(A) to retain for its own account (i) payments made on account of any such claim by any Person (other than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third Person, and (iii) 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;

(B) 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 months' period;

127

(C) 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 months' 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 613, would occur within three months; or

(D) to receive payment on any claim referred to in paragraph (B) or (C) of this Section 613, against the release of any property held as security for such claim as provided in paragraph (B) or (C), as the case may be, to the extent of the fair value of such property.

For the purposes of paragraphs (B), (C) and (D) of this Section 613, property substituted after the beginning of such three months' 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 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

128

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 months' period shall be subject to the provisions of this Section 613 as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such three months' 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 months' 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 613 a creditor relationship arising from:

(1) 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;

(2) 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;

(3) 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;

(4) 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 613;

129

(5) 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

(6) 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 613.

(c) For the purposes of this Section 613 only:

(1) 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;

(2) 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 (i) under which the Trustee is also trustee, (ii) which contains provisions substantially similar to the provisions of this Section 613, and (iii) under which a default exists at the time of the apportionment of the funds and property held in such special account;

(3) 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;

(4) 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;

(5) the term "Company" means any obligor upon the Securities; and

130

(6) the term "Federal Bankruptcy Act" means the Bankruptcy Code or Title 11 of the United States Code.

SECTION 614. 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 304, 305, 306, 307, 308 and ll07 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 this Section 614 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 614 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 614, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 614.

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 614, 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.

131

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 614, 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 614.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 614 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 607.

If an appointment with respect to one or more series of Securities is made pursuant to this Section 614, 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.

SECTION 902. Supplemental Indentures with Consent of Holders

Neither the Company nor any agent of the Company (including but not limited to the Paying Agent) will have any responsibility or liability for any aspect relating to payments made or to be made by the Depositary to DTC in respect of the

140

Global Securities of a series or the beneficial interests therein, subject only to limited indemnification rights of the Depository. None of the Company, the Trustee, the Paying Agent, the Depositary or any agent of any of the foregoing will have any responsibility or liability for any aspect relating to payments made or to be made by DTC on account of a Participant's or Indirect Participant's ownership of a beneficial interest in a Global Security or for maintaining, supervising or reviewing any records relating to a Participant's interests in such Global Security.

SECTION 1002. Maintenance of Office or Agency

The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities of any series may be presented or surrendered for payment, and where notices and demands to or upon the Company in respect of the Securities of such series and this Indenture may be served and an office or agency of a Security Exchange Agent/Registrar in such Place of Payment where Securities may be surrendered for registration of transfer or exchange. 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 1003. 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

141

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 1003, that such Paying Agent will:

(1) 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;

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest, if any, on the Securities of that series; and

(3) 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.

142

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 1004. Limitation on Liens

144

(f) (i) Liens on any property or assets acquired from an entity which is merged with or into the Company or a Significant Subsidiary, or any Liens on the property or assets of any corporation, limited liability company or other entity existing at the time such corporation, limited liability company or other entity becomes a Subsidiary of the Company and, in either such case, is not created in anticipation of any such transaction (unless such Lien is created to secure or provide for the payment of any part of the purchase price of such entity); (ii) any Lien on any property or assets existing at the time of acquisition thereof and which is not created in anticipation of such acquisition (unless such Lien was created to secure or provide for the payment of any part of the purchase price of such property or assets); and (iii) any Lien created or outstanding on or over any asset of any company which becomes a Significant Subsidiary on or after the date of the issuance of such Securities where such Lien is created prior to the date on which such company becomes a Significant Subsidiary;

(g) (i) Liens required by any contract, statute or regulation in order to permit the Company or a Significant Subsidiary to perform any contract or subcontract made by it with or at the request of a governmental entity or any department, agency or instrumentality thereof, or to secure partial, progress, advance or any other payments by the Company or a Significant Subsidiary to such governmental unit pursuant to the provisions of any contract, statute or regulation; (ii) any Lien securing industrial revenue, development, pollution control or similar bonds issued by or for the benefit of the Company or a Significant Subsidiary, provided that such industrial revenue, development, pollution control or similar bonds do not provide recourse generally to the Company and/or such Significant Subsidiary; and (iii) any Lien securing taxes or assessments or other applicable governmental charges or levies;

(h) (i) any Lien which arises pursuant to any order of attachment distraint or similar legal process arising in connection with court proceedings and any Lien which secures the reimbursement obligation for any bond obtained in connection with an appeal taken in any court proceeding, so long as the execution or other enforcement of such Lien arising pursuant to such legal process is effectively stayed and the claims secured thereby are being contested in good faith and, if appropriate, by appropriate legal proceedings, and any Lien in favor of a plaintiff or defendant in any action before a court or tribunal as security for costs and/or other expenses; and (ii) any Lien arising by operation of law or by order of a court or tribunal or any Lien arising

145

by an agreement of similar effect, including but not limited to judgment Liens;

(i) any extension, renewal or replacement (or successive extensions, renewals or replacements), as a whole or in part, of any Liens referred to in the foregoing clauses, for amounts not exceeding the principal amount of the Indebtedness secured by the Lien so extended, renewed or replaced, provided that such extension, renewal or replacement Lien is limited to all or a part of the same property or assets that were covered by the Lien extended, renewed or replaced (plus improvements on such property or assets);

(m) any Lien on stock created in connection with a mandatorily convertible or exchangeable stock or debt financing, provided that any such financing may not be secured by or otherwise involve the creation of a Lien on any capital stock of MHC or MidAmerican Energy or any successor thereto.

Notwithstanding the foregoing, the Company and/or a Significant Subsidiary may create Liens over any of their respective property or assets, so long as the aggregate amount of Indebtedness secured by all such Liens (excluding therefrom the amount of Indebtedness secured by Liens set forth in clauses (a) through (m), inclusive, above) does not exceed 10% of Consolidated Net Tangible Assets in the aggregate calculated as of the date of creation of such Liens (based upon the Consolidated Net Tangible Assets appearing on the most recently available balance sheet for the most recently concluded calendar quarter).

SECTION 1005. Limitation on Distributions

If this covenant shall be made applicable to the Securities of a particular series, the Company covenants and agrees that prior to the Effective Date, it shall not

146

declare, recommend, make or pay any Distribution to any of its shareholders except to the extent necessary to consummate the Transactions. If this covenant shall be made applicable to the Securities of a particular series, from and after the Effective Date, the Company covenants and agrees that, so long as any Securities of that series remain outstanding, the Company shall not declare, recommend, make or pay any Distribution to any of its shareholders unless there exists no Event of Default and no such Event of Default will result from the making of such Distribution and either:

(a) at the time and as a result of such Distribution, the Company's Leverage Ratio does not exceed 0.67:1 and the Company's Interest Coverage Ratio is not less than 2.2:1; or

(b) (if the Company is not in compliance with the foregoing ratios) at such time its senior secured long-term debt rating from the Rating Agencies is at least BBB (or its then equivalent) with S&P and DCR and Baa2 (or its then equivalent) with Moody's.

The foregoing restriction on Distributions shall cease to be in effect if the Rating Agencies confirm that without the restrictions contained in this Section 1005 the Company's senior secured long term debt would still be rated at least BBB+ (or its then equivalent) from each of S&P and DCR and Baa1 (or its then equivalent) from Moody's. If the restriction on Distributions set forth in this
Section 1005 ceases to be in effect, the Company will be under no obligation to reinstate such restriction or otherwise observe its terms in the event such ratings are thereafter lowered or withdrawn.

In order to obtain the release of the restriction on Distributions, the Company shall deliver to the Trustee written confirmation from each Rating Agency of the ratings conditions as described in the preceding paragraph. Securities of any series which are entitled to the benefit of this Section 1005 and are authenticated and delivered after the release of the restriction on Distributions may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to the current inapplicability of such restriction.

(c) From and after the Effective Date, the Company shall cause its Significant Subsidiaries to engage only in (x) those types of businesses and other activities in which the Company or any of its direct or indirect subsidiaries or controlled partnerships or joint ventures (collectively, "MidAmerican Group") are engaged on the date hereof (including, without limitation, any geographic or other expansion of such businesses or activities) and (y) any other business or activity which is deemed necessary, useful or desirable in connection with such existing businesses and activities or any such permitted additional geographic or other expansions of such businesses and activities.

(b) The Company and its Significant Subsidiaries are not required to comply with clauses (1) through (7) of Section 1009(a) above, in any particular instance if the failure to comply in such instance would not reasonably be expected to have a Material Adverse Effect.

(b) In the event that subsequent to the Rating Event Date, the Reference Securities shall thereafter be rated less than Baa3 by Moody's or less than BBB- by each of S&P and DCR (or such other rating agency selected by the Company as provided in Section 1010(a)(i) above), then the operational covenants contained in Section 1009 of this Indenture shall not be reinstated.

SECTION 1011. Statement by Officers as to Default

The Company will give the Trustee notice, in the form of an Officers' Certificate, of any Event of Default relating to the Company or of any condition or event which, with the giving of notice or the lapse of time or both, would constitute an Event of Default relating to the Company within five (5) days after the occurrence of such Event of Default becomes known to the Company, and of the measures it is taking to remedy such Event of Default.

The Company will deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers' Certificate, stating that in the course of the performance by the signers thereof of their duties as Officers of the Company they would normally have knowledge of any default by the Company in the performance and observance of any of the covenants contained in the Indenture, stating whether or not the signers have knowledge of any such default without regard to any period of grace or requirement of notice and, if so, specifying each such default of which such signer has knowledge and the nature thereof.

The election of the Company to redeem any Securities shall be authorized by a Board Resolution and evidenced by an Officers' Certificate. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities prior to the expiration of

152

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.

SECTION 1103. Selection by Trustee of Securities to Be Redeemed

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.

Securities shall be excluded from eligibility for selection for redemption if they are identified by certificate number in a written statement signed by an authorized officer of the Company and delivered to the Security Exchange Agent/Registrar at least 45 days prior to the Redemption Date as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Company or (b) an entity specifically identified in such written statement which is an Affiliate of the Company.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

(2) the Redemption Price,

(3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed,

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(5) the place or places where such Securities are to be surrendered for payment of the Redemption Price, and

(6) that the redemption is for a sinking fund, if such is the case.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company.

SECTION 1105. Deposit of Redemption Price

On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in same day funds sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date (to the extent that such amounts are not already on deposit at such time in accordance with the provisions of Sections 401, 402 or 1012).

SECTION 1106. Securities Payable on Redemption Date

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for

154

redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, and in the case of Registered Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 306.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

SECTION 1107. Securities Redeemed in Part

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 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. In the case of a partial redemption of the Global Securities, DTC (and, in turn, its Participants) shall have the responsibility to select the interests in such Global Securities to be redeemed in accordance with Applicable Procedures.

ARTICLE XII

SINKING FUNDS

155

SECTION 1201. Applicability of Article

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 301 for Securities of such series.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment". If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

SECTION 1202. Satisfaction of Sinking Fund Payments with Securities

In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Company may at its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Company or receive credit for Securities of such series (not previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Company and delivered to the Trustee for cancellation pursuant to Section 311, (b) receive credit for optional sinking fund payments (not previously so credited) made pursuant to this Section 1202, or (c) receive credit for Securities of such series (not previously so credited) redeemed by the Company through any optional redemption provision contained in the terms of such series. Securities so delivered or credited shall be received or credited by the Trustee at the sinking fund Redemption Price specified in such Securities.

SECTION 1203. Redemption of Securities for Sinking Fund

Not less than 30 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate specifying (a) the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, (b) whether or not the Company intends to exercise its right, if any, to make an optional sinking fund payment with respect to such series on the next ensuing sinking fund payment date and, if so, the amount of such optional sinking fund payment, and (c) the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering

156

and crediting Securities of that series pursuant to Section 1202, and will also deliver to the Trustee any Securities to be so delivered. Such written statement shall be irrevocable and upon its receipt by the Trustee the Company shall become unconditionally obligated to make all the cash payments or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Company, on or before any such 30th day, to deliver such written statement and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Company (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect therefor and (ii) that the Company will make no optional sinking fund payment with respect to such series as provided in this Section 1203.

Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1105, 1106 and 1107.

The Trustee shall not redeem or cause to be redeemed any Security of a series with sinking fund moneys or mail any notice of redemption of Securities of such series by operation of the sinking fund during the continuance of a default in payment of interest with respect to Securities of that series or an Event of Default with respect to the Securities of that series except that, where the mailing of notice of redemption of any Securities shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Company a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such default or Event of Default, be deemed to have been collected under Article Five and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 513 or the default or Event of Default cured on or before the 30th day preceding the sinking fund payment date, such moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section 1203 to the redemption of such Securities.

No action at a meeting of Holders shall be effective unless approved by Persons holding or representing Securities of a series in the aggregate principal amount required by the provision of this Indenture pursuant to which such action is being taken.

159

Any action taken by the Holders of the percentage in aggregate principal amount of the Holders specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders of all the Securities.

ARTICLE XIV

SECTION 1402. Delivery of Collateral. Any and all certificates or instruments representing or evidencing the Collateral shall be delivered to and held by or on behalf of the Trustee and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Trustee. The Trustee shall have the right, at any time after the occurrence and during the continuance of an Event of Default, in its discretion and without notice to the Company, to transfer to or to register in the name of the Trustee or any of its nominees any or all of the Collateral. In addition, the Trustee shall have the right at any time to exchange certificates or instruments representing or evidencing Collateral for certificates or instruments of different denominations.

SECTION 1403. Representations and Warranties. The Company hereby represents and warrants on the date of original issuance of Securities under this Indenture and upon each date the Company acquires any rights in property that constitutes "Collateral" hereunder as follows:

(a) It is the record and beneficial owner of the MAVH Inc. Pledged Shares described on Schedule I, free and clear of any Lien, except for the Lien created by this Indenture; and effective as of the MidAmerican Merger the Company will be the record and beneficial owner of the MHC Inc. Pledged Shares described on Schedule I as revised pursuant to Section 1404(ii), free and clear of any Lien, except for the Lien created by this Indenture.

(b) It has full corporate power, authority and legal right to pledge all the Collateral pledged by it pursuant to this Indenture.

161

(c) The MAVH Inc. Pledged Shares described on Schedule I have been, and all shares of stock of MHC Inc. that will be described on Schedule I as revised pursuant to Section 1404(ii) will be, duly authorized and are validly issued, fully paid and non-assessable.

(d) The pledge in accordance with the terms of this Indenture creates a valid and perfected first priority Lien on the MAVH Inc. Collateral and, at the time of the MidAmerican Merger, will create a valid and perfected first priority Lien on all shares of stock of MHC Inc. identified on Schedule I after revised in accordance with Section 1404(ii), in each case securing the payment and performance of the obligations of the Company under this Indenture and the Securities.

(e) The shares described in Schedule I hereto represent 100% of the shares of MAVH Inc. Common Stock owned by the Company on the date of this Indenture.

(f) The number of shares of stock of MHC Inc. that will be described in Schedule I as revised pursuant to Section 1404(ii) will at the time of the MidAmerican Merger represent 100% of the shares of MHC Inc. stock owned by the Company on the date of the MidAmerican Merger and at such time MHC Inc. will be a wholly owned subsidiary of the Company.

(g) The chief executive office of the Company is located (i) prior to the MidAmerican Merger, at 302 South 36th Street, Suite 400, Omaha, Nebraska 68131 and (ii) on and after the MidAmerican Merger, at 666 Grand Avenue, Des Moines, Iowa 50303.

SECTION 1404. Further Assurances. The Company agrees that at any time and from time to time, at the expense of the Company, the Company will promptly execute and deliver all further instruments and documents and take all further action that may be necessary or that the Trustee may reasonably request in order to perfect and protect any Lien granted or purported to be granted hereby or to enable the Trustee to exercise and enforce its rights and remedies in accordance with the terms hereof with respect to any Collateral. Without limiting the foregoing, the Company shall: (i) prior to the MidAmerican Merger, promptly following the issuance by MAVH Inc. of any shares of MAVH Inc. stock after the date of original issuance of Securities under this Indenture, deliver all certificates evidencing such shares to the Trustee as MAVH Inc. Collateral and provide to the Trustee a revised Schedule I, (ii) upon consummation of the MidAmerican Merger, deliver to the Trustee all certificates evidencing shares of stock of MHC Inc. and provide to the Trustee a revised Schedule I

162

and (iii) not establish a new chief executive office (except as contemplated by
Section 1403(g)) until it has given the Trustee at least 30 days' prior written notice of its intention to do so, clearly describing in such notice the intended new location of its chief executive office and providing such other information as the Trustee may reasonably request. Any revised Schedule I furnished pursuant to clause (i) or (ii) shall reflect any changes made necessary by the applicable acquisition or release, at which time the Company shall be deemed to make the applicable representations and warranties set forth in paragraphs (a)-(d) and
(f) of Section 1403 with respect to such Schedule I, as so revised.

SECTION 1405. Dividends; Voting Rights. (a) Notwithstanding any other provision of this Agreement, so long as no Event of Default has occurred and is continuing, all the Liens created hereunder in respect of any dividends or distributions in respect of the Pledged Securities shall be released upon the payment of such dividends or distributions and, upon such payment, such dividends or distributions shall cease to be MAVH Inc. Collateral and/or Collateral, as the case may be.

(b) Upon the occurrence and during the continuance of an Event of Default and upon written notice thereof from the Trustee to the Company, the Trustee shall be entitled to receive and retain as Collateral all dividends paid and distributions made in respect of the Pledged Shares, whether so paid or made before or after any Event of Default. Any such dividends shall, if received by the Company, be received in trust for the benefit of the Trustee, be segregated from the other property or funds of the Company and be forthwith delivered to the Trustee as Collateral in the same form as so received (with any necessary endorsement).

(c) As long as no Event of Default shall have occurred and be continuing and until written notice thereof from the Trustee to the Company, the Company shall be entitled to receive all dividends and other distributions and to exercise any and all voting and other consensual rights relating to Pledged Shares or any part thereof for any purpose; provided, however, that no vote shall be cast, and no consent, waiver or ratification given or action taken, which would be inconsistent with or violate any provision of this Indenture or the Securities.

(d) Upon the occurrence and during the continuance of an Event of Default, all rights of the Company to exercise the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 1405(c) shall cease upon notice from the Trustee to the Company and upon the giving of such notice all such rights shall thereupon be vested in the Trustee who shall thereupon have the sole right to exercise such voting and other consensual rights during the continu-

163

ance of such Event of Default; provided that such rights shall revert to the Company when such Event of Default is cured or otherwise ceases to exist.

(e) In order to permit the Trustee to exercise the voting and other consensual rights which it may be entitled to exercise pursuant to Section 1405(d), and to receive all dividends and distributions which it may be entitled to receive under Section 1405(b), the Company shall, if necessary, upon written notice of the Trustee, from time to time execute and deliver to the Trustee such instruments as the Trustee may reasonably request.

SECTION 1406. Trustee Appointed Attorney-in-Fact. The Company hereby appoints the Trustee as the Company's attorney-in-fact, with full authority in the place and stead of the Company and in the name of the Company or otherwise, from time to time in the Trustee's discretion but only after the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument which the Trustee may deem necessary or advisable in order to accomplish the purposes of this Article XIV, including to endorse and collect all instruments made payable to the Company representing any dividend, interest payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same. This power, being coupled with an interest, is irrevocable.

SECTION 1407. Trustee May Perform. If the Company fails to perform any agreement contained in this Article XIV, the Trustee may itself perform, or cause performance of, such agreement, and the expenses of the Trustee incurred in connection therewith shall be payable by the Company under Section 607.

SECTION 1408. Trustee's Duties. The powers conferred on the Trustee under this Article XIV are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys and Collateral actually received by it hereunder, the Trustee shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

SECTION 1409. Remedies upon Event of Default. If any Event of Default shall have occurred and be continuing, the Trustee may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies provided a secured party upon the default of a debtor under the Uniform Commercial Code at that time, and the Trustee may also, with notice as specified below, sell the Collateral or any part thereof in one

164

or more parcels at public or private sale, at any exchange, broker's board or at any of the Trustee's offices or elsewhere, for cash, on credit or for future delivery, upon such terms as the Trustee may determine to be commercially reasonable. The Trustee agrees to provide at least 10 days' written notice to the Company of the time and place of any public sale or the time after which any private sale is to be made and such notice shall constitute reasonable notification. The Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned and notified at that time. The Trustee shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any private sale conducted in a commercially reasonable manner. If so sold, the Company hereby waives any claims against the Trustee arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Trustee accepts the first offer received and does not offer such Collateral to more than one offeree.

The Company recognizes that, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws, the Trustee may be compelled, with respect to any sale of all or any part of the Collateral, to limit purchasers to those who will agree, among other things, to acquire such securities for their own account, for investment, and not with a view to the distribution or resale thereof. The Company acknowledges and agrees that any such sale may result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions and, notwithstanding such circumstances, agrees that any such sale shall be deemed to have been made in a commercially reasonable manner with respect to such restrictions. The Trustee may, but shall be under no obligation, to delay the sale of any of the Pledged Shares for the period of time necessary to permit the Company to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if the Company would agree to do so.

SECTION 1410. Application of Proceeds. Upon the occurrence and during the continuance of an Event of Default and after the acceleration of the Securities pursuant to Section 502 (so long as such acceleration has not been rescinded), any cash held by the Trustee as Collateral and all cash proceeds received by the Trustee in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral, shall be applied by the Trustee in the manner specified in Section 506.

165

SECTION 1411. Continuing Lien. Subject to Section 1405(a), Indenture shall create a continuing Lien on the Collateral that shall (i) remain in full force and effect until all Obligations have been paid and/or satisfied in full, (ii) be binding upon the Company and its successors and assigns and (iii) enure to the benefit of the Trustee and its successors, transferees and assigns.

SECTION 1412. Certificates and Opinions. The Company shall comply with ss. 314(b) of the TIA, relating to Opinions of Counsel regarding the Lien of this Indenture and Officers' Certificates or other documents regarding fair value of the Collateral, to the extent such provisions are applicable.

SECTION 1413. Additional Agreements. The Company agrees that, upon the occurrence and during the continuance of a Default hereunder, it will, at any time and from time to time, upon the written request of the Trustee, use its best efforts to take or to cause the issuer of the Pledged Shares and any other securities distributed in respect of the Pledged Shares (collectively with the Pledged Shares, the "Pledged Securities") to take such action and prepare, distribute or file such documents, as are required or advisable in the reasonable opinion of counsel for the Trustee to permit the public sale of such Pledged Securities. The Company further agrees, upon such written request referred to above, to use its best efforts to qualify, file or register, or cause the issuer of such Pledged Securities to qualify, file or register, any of the Pledged Securities under the Blue Sky or other securities laws of such states as may be requested by the Trustee and keep effective, or cause to be kept effective, all such qualifications, filings or registrations. The Company will bear all costs and expenses of carrying out its obligations under this
Section 1413. The Company acknowledges that there is no adequate remedy at law for failure by it to comply with the provisions of this Section 1413 and that such failure would not be adequately compensable in damages, and therefore agrees that its agreements contained in this Section 1413 may be specifically enforced.

ARTICLE XV

MISCELLANEOUS

SECTION 1501. Consent to Jurisdiction; Appointment of Agent to Accept Service of Process

166

(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 1633 Broadway, New York, New York 10019, 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 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 Four 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 1501 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or

167

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

168

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.

SECTION 1502. Counterparts

This instrument 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.

169

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed by their respective officers or directors duly authorized thereto, all as of the day and year first above written.

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 will be redeemable in whole or in part, at the option 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 0 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 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 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.

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.

The Trustee may conclusively rely on an Officers' Certificate setting forth the calculation of the Redemption Price, which Officers' Certificate shall be delivered to the Trustee prior to the Redemption Date.

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. MANDATORY REDEMPTION

In the event that (i) the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (ii) CalEnergy elects to abandon the MidAmerican Merger, or the MidAmerican Merger Agreement is terminated, in either case, on or prior to September 7, 1999, for any reason, the Company shall redeem all the Securities on the Mandatory Redemption Date, in cash at a redemption price (the "Mandatory Redemption Price") equal to the aggregate principal amount thereof plus accrued and unpaid interest thereon to the earlier of (a) September 27, 1999, in the event that the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (b) the 20th day (or if such day is not a Business Day, the first Business Day thereafter) following the occurrence of an event described in (ii) above (such earlier date being referred to herein as the "Mandatory Redemption Date").

Notice of Redemption pursuant to this paragraph 3 shall be given as provided for in the Indenture promptly after the occurrence of the event triggering such mandatory redemption.

Unless the Company defaults in payment of the Mandatory Redemption Price, from and after the Mandatory Redemption Date, the Securities of this series 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 Mandatory Redemption Price thereof.

4. 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.

5. 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.

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 recision 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

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 on 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.

7. TRANSFER AND EXCHANGE; DENOMINATIONS

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.

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 $175,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series will be redeemable in whole or in part, at the option 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 15 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 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.

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.

The Trustee may conclusively rely on an Officers' Certificate setting forth the calculation of the Redemption Price, which Officers' Certificate shall be delivered to the Trustee prior to the Redemption Date.

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.

3. MANDATORY REDEMPTION

In the event that (i) the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (ii) CalEnergy elects to abandon the MidAmerican Merger, or the MidAmerican Merger Agreement is terminated, in either case, on or prior to September 7, 1999, for any reason, the Company shall redeem all the Securities on the Mandatory Redemption Date, in


cash at a redemption price (the "Mandatory Redemption Price") equal to the aggregate principal amount thereof plus accrued and unpaid interest thereon to the earlier of (a) September 27, 1999, in the event that the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (b) the 20th day (or if such day is not a Business Day, the first Business Day thereafter) following the occurrence of an event described in (ii) above (such earlier date being referred to herein as the "Mandatory Redemption Date").

Notice of Redemption pursuant to this paragraph 3 shall be given as provided for in the Indenture promptly after the occurrence of the event triggering such mandatory redemption.

Unless the Company defaults in payment of the Mandatory Redemption Price, from and after the Mandatory Redemption Date, the Securities of this series 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 Mandatory Redemption Price thereof.

4. DEFEASANCE

5. 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 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 recision 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

ture 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 from the Holder, request and offer of indemnity shall have failed to institute any such proceeding.

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 on 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 this series are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination as requested by the Holder surrendering the same.

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.

8. 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.

9. 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.

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 $325,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series will be redeemable in whole or in part, at the option 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 25 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 corpo-


rate 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 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.

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.

The Trustee may conclusively rely on an Officers' Certificate setting forth the calculation of the Redemption Price, which Officers' Certificate shall be delivered to the Trustee prior to the Redemption Date.

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 Princi-


pal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.

Notice of Redemption pursuant to this paragraph 3 shall be given as provided for in the Indenture promptly after the occurrence of the event triggering such mandatory redemption.

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 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

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 on 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.

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 $175,000,000.

2. OPTIONAL REDEMPTION

The Securities of this series will be redeemable in whole or in part, at the option 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 0 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 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.

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.

The Trustee may conclusively rely on an Officers' Certificate setting forth the calculation of the Redemption Price, which Officers' Certificate shall be delivered to the Trustee prior to the Redemption Date.

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. MANDATORY REDEMPTION

In the event that (i) the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (ii) CalEnergy elects to abandon the MidAmerican Merger, or the MidAmerican Merger Agreement is terminated, in either case, on or prior to September 7, 1999, for any reason, the Company shall redeem all the Securities on the Mandatory Redemption Date, in cash at a redemption price (the "Mandatory Redemption Price") equal to the aggregate principal amount thereof plus accrued and unpaid interest thereon to the earlier of (a) September 27, 1999, in the event that the MidAmerican Merger is not consummated on or prior to September 7, 1999 or (b) the 20th day (or if such day is not a Business Day, the first Business Day thereafter) following the occurrence of an event described in (ii) above (such earlier date being referred to herein as the "Mandatory Redemption Date").

Notice of Redemption pursuant to this paragraph 3 shall be given as provided for in the Indenture promptly after the occurrence of the event triggering such mandatory redemption.

Unless the Company defaults in payment of the Mandatory Redemption Price, from and after the Mandatory Redemption Date, the Securities of this series 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 Mandatory Redemption Price thereof.*

4. 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.

5. 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


*Include if Exchange Note is a Global Security.

*Include if Exchange Note is issued prior to the MidAmerican Merger.


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 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 recision 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 from the Holder, request and offer of indemnity 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.

6. 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 on 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 uncondi-


tional, 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.

7. TRANSFER AND EXCHANGE; DENOMINATIONS

The Securities of this series are issuable only in registered form, without coupons, in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination as requested by the Holder surrendering the same.

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.

8. 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.

Subject to the terms and limitations of Section 2(c), such Exchange Offer Registration Statement may also cover any resales of Exchange Securities by any Restricted Person, in the manner or manners designated by them which, in any event, is reasonably acceptable to the Company.

If, upon consummation of the Exchange Offer, the Initial Purchasers hold Initial Purchaser Securities, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Exchange Offer, shall issue and deliver to the Initial Purchasers upon the written request of the Initial Purchasers, and the delivery of the Initial Purchaser Securities to the Company, in exchange (the "Private Exchange") for the Initial Purchaser Securities, a like amount of debt securities of the Company issued under the Indenture and identical in all material respects (including the existence of restrictions on transfer under the Securities Act and the securities law of the several states of the United States) to the Securities (the "Private Exchange Securities").

The Company shall, use its reasonable best efforts, for the benefit of the holders, at the Company's cost, to (i) cause the Exchange Offer Registration


Statement to become effective under the Securities Act at least 30 days prior to the Effective Date, (ii) keep the Exchange Offer open for a period of not less than the shorter of (A) the period ending when the last remaining Security is tendered into the Exchange Offer and (B) 30 days from the date notice is mailed to the holders of Securities (provided that in no event shall such period be less than the period required under applicable Federal and state securities laws), and (iii) maintain such Exchange Offer Registration Statement continuously effective for a period (the "Exchange Period") of not less than the longer of (A) the period until the consummation of the Exchange Offer and (B) 120 days after the effectiveness of the Exchange Offer Registration Statement, provided however, that in the event that all resales of Exchange Securities (including, subject to the time periods set forth herein, any Resale Securities and including, subject to the time periods set forth herein, any resales by Exchanging Dealers) covered by such Exchange Offer Registration Statement have been made, the Exchange Offer Registration Statement need not remain continuously effective for the period set forth in clause (B) above. Promptly following the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall (x) accept for exchange all the 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 Securities so accepted for exchange; and (z) cause the Trustee to authenticate and deliver promptly to each Holder of the Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Securities of such Holder so accepted for exchange. Upon consummation of the Exchange Offer, the Company shall deliver to the Trustee under the Indenture for cancellation all Securities tendered by the holders thereof pursuant to the Exchange Offer and not withdrawn prior to the date of consummation of the Exchange Offer. Each Restricted Person shall notify the Company promptly after reselling all Resale Securities held by such Restricted Person which are covered by any such Registration Statement.

Each holder of Registrable Securities to be exchanged in the Exchange Offer (other than any Restricted Person) shall be required as a condition to participating in the Exchange Offer to represent that (i) it is not an Affiliate of the Company, (ii) any Exchange Securities to be received by it shall be acquired in the ordinary course of its business and (iii) that at the time of the consummation of the Exchange Offer it shall have no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities. Upon consummation of an Exchange Offer in accordance with this Section 2 and compliance with the other provisions of this Section 2, the Company shall, subject to Sections 2(b) and 2(c), have no further obligation to register Registrable Securities pursuant to Section 3(a) of this Agreement; provided that the


other provisions of this Agreement shall continue to apply as set forth in such provisions.

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 certain information regarding such Exchanging Dealer's prospectus delivery requirements on the cover page thereto, the "Exchange Offer Procedures" section and 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 Private Exchange Securities acquired in exchange for Securities constituting any portion of an unsold allotment is required to deliver a prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale.

(a) In the event that the Company reasonably determines in good faith that (i) the Exchange Securities would not, upon receipt in the Exchange Offer by any holder of Registrable Securities (other than (x) any Restricted Person (including the Initial Purchasers as holders of Initial Purchaser Securities), and (y) any holder who is not acquiring such Exchange Securities in the ordinary course of business or who has an arrangement with any person to participate in the distribution of such Exchange Securities) be tradeable by each holder thereof without restriction under the Securities Act and the Exchange Act and without restriction under applicable blue sky or state securities laws, (ii) after conferring with counsel, the Commission is unlikely to permit the Exchange Offer Registration Statement to become effective prior to the Effective Date (except in the circumstances set forth in Section 2(c)) or (iii) the Exchange Offer may not be made in compliance with applicable laws, then the Company shall promptly deliver notice thereof (the "Shelf Notice") to the holders of such Registrable Securities and the Trustee and shall thereafter file an Initial Shelf Registration Statement pursuant to, and otherwise comply with, the provisions of Section 3(a). Following the delivery of a Shelf Notice in accordance with this Section 2(b) and compliance with Section 3(a), the Company shall not have any further obligation under this Section 2.
(b)
(c) In the event that (i) at the time of the Exchange Offer there are outstanding any Initial Purchaser Securities, or (ii) the Company reasonably determines in good faith that (x) the Exchange Securities would not, upon consummation of any


resale thereof by a Restricted Person to any Person other than another Restricted Person, be tradeable by each holder thereof without restriction under the Securities Act (other than applicable prospectus requirements) and the Exchange Act and without restriction under applicable blue sky or state securities laws or (y) the Commission is unlikely to permit the Exchange Offer Registration Statement to become effective prior to the Effective Date solely because such Registration Statement covers resales of the Exchange Securities by Restricted Persons, then the Company shall promptly deliver a Shelf Notice to the Restricted Persons who are holders of Registrable Securities and the Trustee, and the Company shall thereafter file an initial Shelf Registration Statement with respect to any such Registrable Securities pursuant to, and otherwise comply with, the provisions of Section 3(a); provided that such Initial Shelf Registration Statement shall only cover resales of Registrable Securities by Restricted Persons if a Shelf Notice is not then otherwise required to be delivered pursuant to Section 2(b) and provided further that such Initial Shelf Registration Statement covering Registrable Securities held by Restricted Persons shall be kept effective for at least a period of 120 days and is not required to remain effective with respect to such Registrable Securities held by Restricted Persons thereafter. Following the delivery of a Shelf Notice in accordance with this Section 2(c) and compliance with Section 3(a), the Company shall not have any further obligation under this Section 2 with respect to the filing of an offer to exchange the Registrable Securities held by the Restricted Persons (including, without limitation, any obligation to provided that an Exchange Offer Registration Statement filed pursuant to Section 2(a) cover resales of Exchange Securities by Restricted Persons); provided that the provisions of this Section 2 shall otherwise remain in full force and effect with respect to Registrable Securities held by any person other than a Restricted Person.

(d)

SECTION 3. Shelf Registration; Registrable Securities. With respect to the Registrable Securities, if a Shelf Notice is delivered in accordance with
Section 2(b) or (c) of this Agreement, then the Company shall comply with the following provisions of this Section 3:

(a) Initial Shelf Registration. The Company shall prepare and cause to be filed with the Commission a Registration Statement for an offering to be made on a continuous basis other than pursuant to an Underwritten Offering pursuant to Rule 415 covering all of the Registrable Securities (or, if a Shelf Notice is delivered solely pursuant to Section 2(c), all of the Registrable Securities held by any Restricted Persons) (the "Initial Shelf Registration Statement"); provided, however, that no holder shall be entitled to have its Registrable Securities covered by such Initial Shelf Registration Statement unless such holder agrees in writing, within 10 Business Days after actual receipt of a request therefrom, to be bound by all the provisions of this


Agreement applicable to such a holder. No holder shall be entitled to the benefits of Section 4 of this Agreement unless and until such holder shall have provided all information reasonably requested by the Company (after conferring with counsel), and such holder shall not be entitled to such benefits with respect to any period during which such information was not provided. Each holder to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such holder not materially misleading. The Initial Shelf Registration Statement shall be an appropriate form permitting registration of such Registrable Securities for resale by the holders thereof in the manner or manners reasonably designated by them (but excluding any Underwritten Offerings). The Company shall use its reasonable best efforts to (A) cause the Initial Shelf Registration Statement to be declared effective under the Securities Act on or prior to the Effective Date and (B) keep the Initial Shelf Registration Statement continuously effective under the Securities Act for a period of two years after the Closing Date (subject to extension pursuant to the last paragraph of Section 5 and subject, with respect to Registrable Securities held by Restricted Persons, to the limitations set forth in Section 2(c)) (such two-year period, as it may be extended, being the "Effective Period"), or such shorter period ending when (1) all Registrable Securities covered by the Initial Shelf Registration Statement have been sold or (2) a Subsequent Shelf Registration Statement covering all of such Registrable Securities remaining unsold has been declared effective under the Securities Act or (3) all Registrable Securities may be sold pursuant to subsection (k) of Rule 144.
(b)
(c) 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 (1) such action is required by applicable law, or (2) such action is taken by the Company in good faith and for valid business reasons (not including 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 5(b) hereof, if applicable. Notwithstanding the occurrence of any event referred to in the immediate preceding sentence (a "Suspension"), such event shall not suspend, postpone or in any other manner affect the running of the time period after which an Illiquidity Event shall be deemed to occur and, if the filing or effectiveness of the Registration Statement is postponed or suspended as a result of a Suspension, an Illiquidity Event shall nonetheless exist if all other requirements set forth for the occurrence of an Illiquidity Event shall be satisfied, and the provisions of
Section 4 requiring the accrual


payment of additional interest, as set forth in such Section, on the Registrable Securities, shall be applicable.

(e) Subsequent Shelf Registrations. If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during the Effective Period, the Company may attempt to obtain the withdrawal of any order suspending the effectiveness thereof, and may amend such Initial Shelf Registration Statement or Subsequent Shelf Registration Statement in a manner reasonably expected to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional "shelf" Registration Statement applicable to the Securities pursuant to Rule 415 covering all of such Registrable Securities remaining unsold (a "Subsequent Shelf Registration Statement"). If a Subsequent Shelf Registration Statement is declared effective, the Company shall use its reasonable best efforts to keep such Shelf Registration Statement continuously effective for a period after the date of such effectiveness equal in length to the length of the Effective Period plus the aggregate number of days from the date of the order suspending the effectiveness of the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement to the date of the effectiveness of the Subsequent Shelf Registration Statement. As used herein, the term "Shelf Registration Statement" means the Initial Shelf Registration Statement and any Subsequent Shelf Registration Statement.


SECTION 4. Additional Interest for Illiquidity.

(a) The Company acknowledges and agrees that the Initial Purchasers (and any subsequent holders of the Securities) in reliance on the Company's covenant to use its reasonable best efforts to (i) cause to become effective on or prior to the Effective Date, (A) the Exchange Offer Registration Statement and to consummate the Exchange Offer or (B) an Initial Shelf Registration Statement, and (ii) maintain the respective effectiveness of such Registration Statements as described herein. The Company further acknowledges and agrees that the failure of the Company to fulfill such covenants will have an adverse effect on the holders of the Securities. Therefore, the Company agrees that from and after the date on which any Illiquidity Event occurs, additional interest (in addition to the interest otherwise payable with respect to the Registrable Securities) shall accrue with respect to the Securities until but not including the date on which such Illiquidity Event shall cease to exist (and provided no other Illiquidity Event with respect to any Securities shall then be continuing), at the rate of one half of one percent (0.50%) per annum, provided, however, that if such Illiquidity Event has not ceased to exist or is not otherwise cured within two years after the consummation of the MidAmerican Merger, such increase in interest rate will become permanent. In each case, such additional interest shall be payable by the Company to the holders of all Securities at the times, in the manner and subject to the same terms and conditions set forth in the Indenture, as nearly as may be, as though the interest rates provided in such Securities had been increased by one half of one percent (0.50%) per annum. Subject to the provisions of this Section 4, the Company agrees that it shall be liable to the holders of all Securities for the payment of any and all additional interest on the Securities that shall accrue pursuant to this
Section 4.

Any such additional interest accrued on any such Securities but unpaid on the date on which such interest ceases to accrue (the "Cure Date") shall be due and payable on the first interest payment date following the next record date following such Cure Date (or the record date occurring on such Cure Date, if such Cure Date is a record date) to the holders of record of such Securities on such record date.

(a) The Company shall promptly notify the holders of the Securities and the Trustee of the occurrence of any Illiquidity Event of which it has knowledge.
(b)
(c) Notwithstanding the foregoing, the Company shall not be required to pay the additional interest described in clause (a) of this Section 4 to a holder with


respect to the Registrable Securities held by such holder if the applicable Illiquidity Event arises by reason of the failure of such holder to provide such information (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 clause (a) of Section 3 to the extent compliance thereof is necessary for the Shelf Registration Statement to be declared effective.

(d)

SECTION 5. Registration Procedures. In connection with the registration of any Registrable Securities or Exchange Securities pursuant to Sections 2 and 3 hereof, the Company shall use its reasonable best efforts to effect such registration to permit the sale of such Registrable Securities or Exchange Securities in accordance with any permitted intended method or methods of disposition thereof, and pursuant thereto the Company shall:

(a) prepare and cause to be filed with the Commission a Registration Statement or Registration Statements as prescribed by Sections 2 and 3 of this Agreement, and use its best efforts to cause each such Registration Statement to become effective and remain effective for the applicable period as provided herein; provided, however, that (i) during the period in which the initial Registration Statement is open for the Restricted Persons, the Company shall afford any Restricted Person which is a holder of Registrable Securities or Exchange Securities and the Special Counsel, upon such holder's written request to the Company, an opportunity to review copies of all such documents proposed to be filed, and (ii) if such filing is pursuant to Section 3, before filing any Registration Statement or Prospectus or any amendments or supplements thereto (including documents that would be incorporated therein by reference after the initial filing of the Registration Statement), the Company shall afford the Special Counsel for all holders of the Registrable Securities covered by such Registration Statement an opportunity to review copies of all such documents proposed to be filed;
(b)
(c) prepare and cause to be filed with the Commission such amendments and post-effective amendments to each Shelf Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable period as provided herein; cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and comply


with the provisions of the Securities Act, the Exchange Act and the rules and regulations of the Commission promulgated thereunder with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented in accordance with the intended methods of disposition by the sellers of Registrable Securities covered thereby set forth therein;

(d)

(e) if a Shelf Registration Statement is filed pursuant to Section 3 hereof, notify the selling holders of Registrable Securities promptly after the Company becomes aware thereof, and confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus or for additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or Prospectus or the initiation of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Securities for offer or sale in any jurisdiction, or the initiation of any proceeding for such purpose, (v) of the existence of any fact known to the Company which results in such Registration Statement or related Prospectus or any document incorporated therein by reference containing any untrue statement of a material fact or omitting 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 (which notice may be accompanied by an instruction that such notice constitutes material non-public information and to suspend the use of the prospectus until the requisite changes have been made, and which instruction shall require that such holders shall not communicate such material non-public information to any third party and shall not sell or purchase, or offer to sell or purchase, any securities of the Company after receipt of such notice) and (vi) if the Company reasonably determines that the filing of a post-effective amendment to such Registration Statement would be appropriate;
(f)
(g) if a Shelf Registration Statement is filed pursuant to Section 3, use its reasonable efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction and, if any such order is issued, to obtain the withdrawal of any such order at the earliest possible moment;
(h)


(i) if a Shelf Registration Statement is filed pursuant to Section 3, furnish to each selling holder of Registrable Securities who so requests (at such holder's address set forth in the Securities Register) without charge, one conformed copy of the Registration Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, all documents incorporated therein by reference and all exhibits (including those incorporated by reference);
(j)
(k) if a Shelf Registration Statement is filed pursuant to Section 3, deliver to each selling holder of Registrable Securities without charge, as many copies of the Prospectus (including each preliminary prospectus) and each amendment or supplement thereto as such persons may reasonably request; and, subject to the last paragraph of this Section 5, the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling holders of Registrable Securities and the underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto;

(l)

(m) prior to any public offering of Registrable Securities, register or qualify, or cooperate with the selling holders of Registrable Securities, the underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions within the United States as the selling holders reasonably request in writing (provided that, if Registrable Securities are offered other than through an Underwritten Offering, the Company agrees to cause its counsel to perform blue sky investigations and file registrations and qualifications required to be filed pursuant to this Section
5(g)); keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective; and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable Registration Statement; provided, however, that the Company will not be required to qualify as a foreign corporation, or to do business, to file a general consent or take any action which would subject it to service of process in any jurisdiction or take any action which would subject itself to taxation in any such jurisdiction;
(n)
(o) if a Shelf Registration Statement is filed pursuant to Section 3, cooperate with the Trustee, and the selling holders of Registrable Securities to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be in a


form eligible for deposit with The Depository Trust Company, and enable such Registrable Securities to be in such authorized denominations and registered in such names as the holders may reasonably request at least three business days prior to any such sale;
(p)
(q) if a Shelf Registration Statement is filed pursuant to Section 3, upon the occurrence of any event contemplated by Section 5(c), prepare a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company so notifies the holders to suspend the use of the Prospectus after the occurrence of such an event, the holders shall suspend use of the Prospectus, and not communicate such material non-public information to any third party, and not sell or purchase, or offer to sell or purchase, any securities of the Company, until the Company has amended or supplemented the Prospectus to correct such misstatement or omission;
(r)
(s) use its reasonable best efforts to cause the Registrable Securities covered by the Registration Statement to continue to be rated by the rating agencies that initially rated the Securities during the period that the 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 Registrable Securities at the rating given the Securities);
(t)
(u) prior to the effective date of the first Registration Statement relating to the Registrable Securities or the Exchange Securities, as the case may be, (i) provide the Trustee with printed certificates for such securities in definitive form or in a global form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for such Registrable Securities or Exchange Securities represented by such certificates;

(v)

(w) if a Shelf Registration Statement is filed pursuant to Section 3, enter into such reasonably required agreements and take all other appropriate actions in order to expedite or facilitate the registration or the disposition of such Registrable Securities;

(x)

(y) in the event of any Underwritten Offering (which shall only be undertaken at the option of the Company), if a Shelf Registration Statement is filed


pursuant to Section 3, make available prior to the filing thereof for inspection by a representative of the holders of a majority in aggregate principal amount of the Registrable Securities being sold, and the Special Counsel, on the one hand, or underwriter on the other hand (collectively, the "Inspectors"), during reasonable business hours, all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries (collectively, the "Records"), and cause the officers, directors and employees of the Company and its subsidiaries to supply all relevant information as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities; provided, however, that, as a condition to supplying such information, the Company shall receive an agreement in writing from the 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 Inspector (other than as to holders of Registrable Securities) and by any holders of Registrable Securities receiving such information, unless (i) disclosure of such information is required pursuant to applicable law or by court or administrative order, (ii) 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 the Registration Statement, Prospectus, or any supplement or post-effective amendment thereto or disclosure is otherwise required by law,
(iii) such information becomes generally available to the public other than as a result of a disclosure by any Inspector or any such holder of Registrable Securities in violation of this Section 5(m) or (iv) such information is approved for release by the Company, in writing;
(z)
(aa) use its best efforts to cause the Indenture or the trust indenture provided for in Section 2, as the case may be, to be qualified under the TIA not later than the effective date of such Registration Statement; and, in connection therewith, cooperate with the Trustee under such Indenture and the holders of the Registrable Securities to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and execute, and use its best efforts to cause such Trustee to execute all documents as may be required to effect such changes, and all other forms and documents required to be filed with the Commission to enable the Indenture to be so qualified in a timely manner; and
(bb)
(cc) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of, the Commission.

(dd)

(ee) For purposes of the covenants set forth in this Section 5, references to a Shelf Registration Statement, including a Shelf Registration Statement filed pursuant to Section 3, shall be deemed to include any Registration Statement, filed pursu-


ant to Section 2, which covers, for the period set forth therein, resales of Exchange Securities held by Restricted Persons as provided in Section 2, and, in connection with such resales such Restricted Persons shall be entitled to exercise all rights, receive all notices and copies of documents, and otherwise receive all benefits afforded to sellers or holders of Registrable Securities under this Section 5 in connection with a Shelf Registration Statement. Without limiting the generality of the foregoing, the Company agrees to fulfill its obligations set forth in Sections 5(a), (b), (c) , (d) , (e) , (f) , (h) , (i) ,
(l) , and (m) with respect to any such Registration Statement filed pursuant to
Section 2 insofar as it covers such resales.
(ff)
(gg) The Company may require each seller of Registrable Securities as to which any registration is being effected, as a condition thereto, to furnish to the Company such information regarding the holder and the distribution of such Registrable Securities as the Company may, from time to time, request in writing, including without limitation stating that (i) it is not an Affiliate of the Company, (ii) the amount of Registrable Securities held by such holder prior to the Exchange Offer, (iii) the amount of Registrable Securities owned by such holder to be exchanged in the Exchange Offer and representing that such holder is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution of the Exchange Securities to be issued, and (iv) it is acquiring the Exchange Securities in its ordinary course of business and to covenant and agree to promptly notify the Company if any such information so provided by such seller ceases to be true and correct and will promptly thereafter furnish the Company with corrected information. The Company may exclude from such registration the Registrable Securities of any Person who fails to furnish such information within a reasonable time after receiving such request.
(hh)
(ii) Each holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5 (c) (ii) , 5 (c) (iii) , 5 (c) (v) or 5 (c) (vi) hereof , such holder shall forthwith discontinue disposition of such. Registrable Securities covered by such Registration Statement or Prospectus until such holder is advised in writing (the "Advice") by the Company that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto and, if so directed by the Company, such holder will deliver to the Company (at its expense) all copies in its possession, other than permanent file copies then in such holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice, or certify in writing as to the destruction thereof. In the event the Company shall give any such notice, the length of the Effective Period shall be extended by the number of days during such period


from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such Registration Statement shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(i) or (y) the Advice.
(jj)
SECTION 6. Delivery of Prospectus; Notification Upon Resale. Each of the Initial Purchasers acknowledges that it is the position of the staff of the Commission that any broker-dealer that receives Exchange Securities for its own account in exchange for Registrable Securities pursuant to the Exchange Offer must deliver a prospectus in connection with any resale of such Resale Securities, By so acknowledging, each such Initial Purchaser shall not be deemed to admit that, by delivering a prospectus, it is an underwriter within the meaning of the Securities Act.

The Initial Purchasers shall notify the Company promptly upon the completion of the resale of the Resale Securities received by the Initial Purchasers pursuant to the Exchange Offer.

SECTION 7. Registration Expenses.

The Company shall bear all expenses incurred in connection with the performance of its obligations under Sections 2, 3 and 4; provided, however, that the Company shall bear or reimburse the holders for the reasonable fees and disbursements of only one counsel, the Special Counsel, in accordance with the terms of the Purchase Agreement; provided, further, however, that if the Company permits an Underwritten Offering, the Company shall not be responsible for any fees and expenses of any underwriter including any underwriting discounts and commissions or any legal fees and expenses of counsel to the underwriters (except for the reasonable fees and disbursements of counsel in connection with state securities or Blue Sky qualification of any of the Registrable Securities or the Exchange Securities).


SECTION 8. Indemnification and Contribution.
(a) The Company agrees to (A) indemnify and hold harmless each holder of Registrable Securities (including the Initial Purchasers which hold Registrable Securities, including Resale Securities, for their own accounts) (each, a "Resale Initial Purchasers") and each person, if any, who controls any such person within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee or agent of each such Person (each a "Holder Indemnified Party") against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them are subject under the Securities Act, the Exchange Act, or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof), arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement covering Registrable Securities held by such person or any Prospectus relating to any such Registration Statement, or any amendment thereof or supplement thereto and all documents incorporated by reference therein, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances in which they were made, not misleading, and (B) reimburse each such Holder Indemnified Party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement or Prospectus, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information relating to such holder provided by such holder to the Company by any holder specifically for use therein (collectively, the "Holder Information"); provided, further, however, that the indemnity obligations arising out of this Section 8 with respect to any untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary Prospectus shall not inure to the benefit of any holder or any controlling Person of such holder if such holder failed to send or deliver to the Person asserting any such losses a copy of the final Prospectus with or prior to the delivery of the written confirmation of the sale of the Registrable Securities or the Exchange Securities, as the case may be, and such final Prospectus would have cured the untrue statement or omission giving rise to such losses. This indemnity agreement will be in addition to any liability which the Company may otherwise have.


(a) As a condition to the inclusion of a holder's Registrable Securities in a Registration Statement, such holder shall agree to (i) indemnify and hold harmless the Company and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, and each director, officer, employee or agent of each such person, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them are subject under the Securities Act, the Exchange Act, or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in a Registration Statement covering Registrable Securities held by such holder or any Prospectus relating to any such Registration Statement or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances in which they were made, not misleading, and (ii) reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; in each and every case under clause (i) and (ii) above to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in such Registration Statement or Prospectus in any amendment thereof or supplement thereto, in reliance upon and in conformity with the Holder Information provided by such holder. This indemnity agreement will be in addition to any liability which any such holder may otherwise have. In no event shall the liability of any selling holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds (net of payment of all expenses) received by such holder upon the sale (or, in the case of Resale Securities, the resale) of the Registrable Securities giving rise to such indemnification obligation.
(b)
(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof (enclosing a copy of all papers served); but the omission to so notify the indemnifying party (i) shall not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such omission results in the forfeiture by the indemnifying party or material impairment of substantial rights and defenses and (ii) shall not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligations 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 shall 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. After notice from the indemnifying party to such indemnified party of its election to so assume the defense of such claim or action, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than costs of investigation; provided that if (i) the defendants in any such action include both the indemnified party and the indemnifying party, the indemnified party shall have received the written opinion of counsel reasonably acceptable to the indemnifying party that representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them, or
(ii) the indemnifying party shall not have employed counsel for the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action, then the indemnified party or parties shall have the right to select one firm of separate counsel (in addition to the fees and expenses of local counsel) to assert any separate legal defenses and to otherwise defend such action on behalf of such indemnified party or parties. No indemnifying party shall be liable for any settlement of any action or claim for monetary damages which an indemnified party may effect without the written consent of the indemnifying party, which consent shall not be unreasonably withheld.

(d)

(e) If the indemnification provided for in Section 8(a) or (b) hereof is for any reason, other than as specified in such provisions, unavailable to or insufficient to hold harmless an indemnified party, then each indemnifying party shall contribute to the aggregate losses, claims, damages or liabilities (or actions in respect thereof) referred to in Section 8(a) or (b) hereof in such proportion as is appropriate to reflect the relative fault and benefits to the Company on the one hand and such holders on the other hand in connection with the statements or omissions which 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 Company and such holders shall be determined by reference to, among other things, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent any untrue statement or omission. The obligations of the holders in this Section 8(d) are several in proportion to their respective obligations hereunder and not joint. Notwithstanding the provisions of this Section 8(d), in no event shall any holder of Registrable Securities be required to contribute any amount which is in excess of (i) the aggregate principal amount of Securities sold or exchanged by such holder less (ii) the amount of any damages that such person has otherwise been required to pay by reason of such alleged untrue statement or 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 Section 8, each Holder Indemnified Party shall have the same rights to contribution as a holder, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each officer, director, employee and agent of such person, shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 8(d). Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section
8(d), notify such party or parties from whom contribution may be sought; but the omission to so notify such party or parties (x) shall not relieve the party or parties from whom contribution may be sought from any liability under this paragraph (d) unless and to the extent it did not otherwise learn of such action and such omission results in the forfeiture by the party or parties from whom contribution may be sought or material impairment of substantial rights and defenses and (y) shall not, in any event, relieve such party or parties from any obligations other than under this Section 8 (d).
(f)
(g) The provisions of this Section 8 will remain in full force and effect, regardless of any investigation made by or on behalf of any holder of Registrable Securities, the Initial Purchasers, the Company or any of the officers, directors or controlling persons referred to in this Section 8 and will survive the sale (or, in the case of Resale Securities, the resale) by a holder of Registrable Securities of such Registrable Securities.
(h)
SECTION 9. Underwritten Registrations (If Any). No holder may participate in any Underwritten Registration, which Underwritten Registration shall only be undertaken at the option of the Company, unless such holder (a) agrees to sell such holder' s Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

SECTION 10. Termination. In the event that no Securities are sold to the Initial Purchasers pursuant to the Purchase Agreement, this Agreement shall automatically terminate, without liability on the part of any party. Upon the fulfillment of all obligations on the part of the Company to register the Securities as set forth herein (including maintaining the effectiveness of any applicable Registration State-


ments), this Agreement shall terminate; provided, that the provisions of Sections 7 and 8 hereof shall survive any termination and remain in full force and effect.

SECTION 11. Miscellaneous.

(a) No Inconsistent Agreements. The Company has not, as of the date hereof, entered into, and shall not, on or after the date hereof, enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the holders of Registrable Securities herein or otherwise conflicts with the provisions hereof.

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of holders of at least a majority of the then outstanding aggregate principal amount of the Registrable Securities (or, after the consummation of any Exchange Offer in accordance with Section 2, of Exchange Securities); provided that, with respect to any matter that directly or indirectly affects the rights of any Restricted Person hereunder occurring within the period in which the Initial Registration Statement is open for the Restricted Persons, the Company shall obtain the written consent of each such Restricted Person against which such amendment, modification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except for 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 holders of Registrable Securities whose securities are being sold or exchanged pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other holders of Registrable Securities may be given by holders of at least a majority in aggregate principal amount of the Registrable 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 provision of the immediately preceding sentence. Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Resale Initial Purchasers and that does not directly or indirectly affect the rights of holders of Registrable Securities or Exchange Securities may be given by each of the Resale Initial Purchasers affected thereby.

(c) Notices. All notices and other communications (including, without limitation, any notices or other communications to the Trustee) provided for or per-


mitted hereunder shall be made in writing and delivered by hand delivery, registered first-class mail, next-day air courier or telecopier:

(i) if to the Company, initially at the address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 11(c).

All such notices and communications shall be deemed to have been duly given: when delivered by hand, if personally delivered; five business days after being deposited in the mail, postage prepaid, if mailed; one business day after being timely delivered to a next-day air courier; and when received, if telecopied.

Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee at the address specified in the Indenture.

(d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including without limitation and without the need for an express assignment or any consent by the Company thereto, subsequent holders of Registrable Securities.

(e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(f) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(g) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. Each of the parties hereto hereby submits to the non-exclusive jurisdiction of the Federal and State Courts of the Borough of Man-


hattan in the City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

(h) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.

Re: Registration Statement on Form S-4; $700,000,000 Aggregate Principal Amount of Senior Secured Notes and Bonds

Ladies and Gentlemen:

In connection with the registration of (i) $200,000,000 5.85% Senior Secured Exchange Notes due 2001 (the "2001 Securities"), (ii) $175,000,00 6.339% Senior Secured Exchange Notes due 2009 (the "2009 Securities") and (iii) $325,000,000 6.927% Senior Secured Exchange Bonds due 2029 (the "2029 Securities" and, collectively with the 2001 Securities and the 2009 Securities, the "Securities") by MidAmerican Funding, LLC, an Iowa limited liability company (the "Registrant"), under the Securities Act of 1933, as amended, on Form S-4 filed with the Securities and Exchange Commission (the "Commission") on November __, 1999 the "Registration Statement"), you have requested our opinion with respect to the matters set forth below.

In our capacity as your special counsel, we have made such legal and factual examinations and inquiries as we have deemed necessary or appropriate for purposes of this opinion.

In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies. As to facts material to the opinions, statements and assumptions expressed herein, we have, with your consent, relied upon

oral or written statements and representations of officers and other representatives of the Registrant and others.

We are opining herein as to the effect on the subject transaction only of the internal laws of the State of New York, including statutory and reported decisional law thereunder, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or as to any matters of municipal law or the laws of any local agencies within any state.

Capitalized terms used herein without definition have the meanings assigned to them in the Registration Statement.

Subject to the foregoing and the other matters set forth herein, it is our opinion that as of the date hereof:

When the Securities have been duly executed, issued, authenticated and delivered by or on behalf of the Registrant, the Securities will constitute legally valid and binding obligations of the Registrant, enforceable against the Registrant in accordance with their terms.

The opinions rendered in the preceding paragraph relating to the enforceability of the Securities are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors; and (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or law, and the discretion of the court before which any proceeding therefor may be brought.

We have not been requested to express, and with your knowledge and consent do not render, any opinion as to the applicability to the obligations of the Registrant under the Indenture and the Securities of Section 548 of the United States Bankruptcy Code or applicable state law (including, without limitation, Article 10 of the New York Debtor and Creditor Law) relating to fraudulent transfers and obligations.

To the extent that the obligations of the Registrant under the Indenture may be dependent upon such matters, we assume for purposes of this opinion that: (i) each of the Registrant and the Trustee (a) is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, (b) has the requisite organizational and legal power and authority to perform its obligations under the Indenture and the Securities, (c) is duly qualified to engage in the activities contemplated by the Indenture and (d) has duly authorized, executed and delivered the Indenture; (ii) the Securities have been duly authorized by all necessary limited liability company action of the Registrant; (iii) the Indenture is the legally valid, binding and enforceable obligation of the Trustee, enforceable against the Trustee in accordance with its terms; and (iv) the Trustee is in compliance, generally and with respect to acting as a trustee under the Indenture, with all applicable laws and regulations. We have also assumed, with your

consent, that the choice of law provisions in the Indenture would be enforced by any court in which enforcement thereof might be sought.

We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm contained under the heading "Legal Matters" in the Prospectus.

Very truly yours,
