         On August 6, 2001, MidAmerican Energy Holdings Company announced that
its wholly owned CE Electric UK plc subsidiary had entered into an agreement to
dispose of its electricity and gas supply assets, related metering businesses
and other properties and to acquire Innogy Holdings plc's Yorkshire Electricity
distribution business. The parties consummated the transaction on September 21,
2001.

         Northern Electric plc, Northern Electric and Gas Limited and Northern
Electric Properties Limited, subsidiaries of CE Electric, sold their electricity
and gas supply assets, related metering businesses and other properties to
Innogy for approximately $364 million ((pounds)257 million) plus working capital
as of June 30, 2001. CE Electric simultaneously purchased Innogy's 94.75%
shareholding in Yorkshire Power Group Limited by way of share purchase for
approximately $338 million ((pounds)239 million) plus working capital as of June
30, 2001. As a result of the purchase, CE Electric indirectly acquired the
subsidiaries of Yorkshire Power Group Limited, through which the distribution
business will be operated.

         The following unaudited pro forma condensed consolidated financial
statements of MidAmerican Energy Holdings Company are based on the historical
consolidated financial statements of MidAmerican Energy Holdings Company and

Group") consummated the acquisition of the predecessor of MidAmerican Energy
Holdings Company ("MEHC") (the "Teton Transaction").  The unaudited pro forma

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                        CONSOLIDATED FINANCIAL STATEMENTS


(1)           The transaction between CE Electric UK and Innogy was consummated
              in British pounds. The pro forma financial statements herein are
              presented in United States dollars computed by multiplying the
              applicable amounts in pounds by exchange rates of 1.5168, 1.4406
              and 1.4163 for the statement of operations for the twelve months
              ended December 31, 2000, the Statement of operations for the six
              months ended June 30, 2001, and the balance sheet as of June 30,
              2001, respectively.

(2)           On March 14, 2000, an investor group including Berkshire Hathaway
              Inc., a director and two executive officers of a predecessor
              company (the "Investor Group") consummated the acquisition of the
              predecessor of MidAmerican Energy Holdings Company ("MEHC") (the
              "Teton Transaction").  The pro forma adjustments included in the
              Merger Adjustments column reflect the net adjustment to amortiza-
              tion required to recognize twelve months amortization of goodwill
              and purchase accounting adjustments related to the Teton Trans-
              action. Additionally, minority interest reflects $10.2 million of
              interest expense related to approximately $455 million in 11%
              nontransferable trust preferred securities invested by Berkshire
              Hathaway at the closing of the Teton Transaction.

(3)           On each pro forma statement of operations presented, the
              Disposition Adjustments column reflects the elimination of the
              revenues and expenses related to CE Electric's electricity and gas
              supply and metering businesses and other properties for the period
              presented.

(4)           The Disposition Adjustments column on the attached pro forma
              balance sheet reflects the elimination of the assets and
              liabilities related to CE Electric's electricity and gas supply
              and metering businesses and other properties as of June 30, 2001,
              adjusted for liabilities retained by Northern Electric. In
              addition, it reflects the consideration received from the
              disposition of the supply and metering businesses and other
              properties as an equity investment and cash.
