Forward-Looking Statements

This report contains statements that do not directly or exclusively relate to
historical facts. These statements are "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995, including, but
not limited to, statements relating to the proposed transaction between
MidAmerican and Constellation Energy and the expected timing and completion of
the transaction. You can typically identify forward-looking statements by the
use of forward-looking words, such as "may," "could," "project," "believe,"
"anticipate," "expect," "estimate," "continue," "intend," "potential," "plan,"
"forecast," and similar terms. These statements are based upon MidAmerican's
current intentions, assumptions, expectations and beliefs and are subject to
risks, uncertainties and other important factors. Many of these factors are
outside MidAmerican's control and could cause actual results to differ
materially from those expressed or implied by MidAmerican's forward-looking
statements.  These factors include, among others:

o    the ability to obtain governmental approvals of the transaction or to
     satisfy other conditions to the transaction on the terms and expected
     timeframe or at all;

o    general economic, political and business conditions in the jurisdictions in
     which MidAmerican's facilities are located;

o    changes in governmental, legislative or regulatory requirements affecting
     MidAmerican or the electric or gas utility, pipeline or power generation
     industries;

o    changes in, and compliance with, environmental laws, regulations, decisions
     and policies that could increase operating and capital improvement costs,
     reduce plant output and/or delay plant construction;

o    the outcome of general rate cases and other proceedings conducted by
     regulatory commissions or other governmental and legal bodies;

o    changes in economic, industry or weather conditions, as well as demographic
     trends, that could affect customer growth and usage or supply of
     electricity and gas or MidAmerican's ability to obtain long-term contracts
     with customers;

o    changes in prices and availability for both purchases and sales of
     wholesale electricity, coal, natural gas, other fuel sources and fuel
     transportation that could have a significant impact on generation capacity
     and energy costs;

o    the financial condition and creditworthiness of MidAmerican's significant
     customers and suppliers;

o    changes in business strategy or development plans;

o    availability, terms and deployment of capital;

o    performance of MidAmerican's generation facilities, including unscheduled
     outages or repairs;

o    risks relating to nuclear generation;

o    the impact of derivative instruments used to mitigate or manage volume and
     price risk and interest rate risk and changes in the commodity prices,
     interest rates and other conditions that affect the value of the
     derivatives;

o    the impact of increases in healthcare costs, changes in interest rates,
     mortality, morbidity and investment performance on pension and other
     postretirement benefits expense, as well as the impact of changes in
     legislation on funding requirements;

o    changes in MidAmerican's and its subsidiaries' credit ratings;

o    unanticipated construction delays, changes in costs, receipt of required
     permits and authorizations, ability to fund capital projects and other
     factors that could affect future generation plants and infrastructure
     additions;

                                       3


o    the impact of new accounting pronouncements or changes in current
     accounting estimates and assumptions on financial results;

o    MidAmerican's ability to successfully integrate future acquired operations
     into its business;

o    other risks or unforeseen events, including litigation and wars, the
     effects of terrorism, embargos and other catastrophic events; and

o    other business or investment considerations that may be disclosed from time
     to time in MidAmerican's filings with the United States Securities and
     Exchange Commission or in other publicly disseminated written documents.

MidAmerican undertakes no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
