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

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:

          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;

          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    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;

     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
