MIDAMERICAN ENERGY COMPANY RESTATED EXECUTIVE DEFERRED COMPENSATION PLAN ARTICLE I ESTABLISHMENT AND PURPOSE 1.1 BACKGROUND OF PLAN. MidAmerican Energy Company presently maintains a deferred compensation plan for selected employees and also maintains certain deferred compensation plans of predecessor employers. This Plan shall replace those arrangements, effective January 1, 1999, and is known as the MidAmerican Energy Company Restated Executive Deferred Compensation Plan (the "Plan"). The Plan shall be maintained as an unfunded plan of deferred compensation for a select group of management or highly compensated employees. The Plan, therefore, is intended to be exempt from the participation, vesting, funding, and fiduciary requirements of Title I of the Employee Retirement Income Security Act of 1974. 1.2 PURPOSE OF PLAN. The purpose of this Plan is to provide certain employees with an additional way to defer portions of their compensation. The plan is also intended to provide Participants with an effective means of deferring all or a portion of short-term incentive bonus payments they are entitled to receive. 1.3 APPLICABILITY OF PLAN. The provisions of this Plan are applicable to Employees who are employed by an Employer on or after January 1, 1999, and, with respect to amounts deferred under any Predecessor Plan, are applicable to participants who still have account balances under any such Plan. 1.4 MERGER OF PREDECESSOR PLANS. For ease of administration, and in recognition of the need to change earnings credit and method of valuation in the Predecessor Plans in light of the anticipated acquisition of MidAmerican Energy Holdings Company by CalEnergy Company, Inc. (through a merger of a subsidiary of CalEnergy with and into MidAmerican Energy Holdings Company ("Merger")), each Predecessor Plan is hereby merged into the Plan, effective January 1, 1999.

ARTICLE 3 ELIGIBILITY AND PARTICIPATION 3.1 ELIGIBILITY. An Employee shall be eligible to participate in this Plan if he or she is a member of a select group of management or highly compensated employees who is approved for participation by the Committee. Participants with account balances in any Predecessor Plan shall automatically be either an active or inactive Participant in this Plan, depending on whether they are an employee of an Employer as of January 1, 1999, in which case he or she is an active Participant, or if not an employee of an Employer on such date, then he or she is an inactive Participant. -4- 3.2 PARTICIPATION. (a) COMMENCEMENT OF PARTICIPATION. An Employee who has satisfied the eligibility requirements of section 3.1 may enroll in the Plan by making the elections described in this Plan. This enrollment shall be effective as of the first day of any Plan Year after the Employee satisfies these eligibility requirements, provided that he or she is still eligible to participate under section 3.1. (b) DURATION OF PARTICIPATION. A Participant shall continue to be an active Participant until he or she ceases to meet the eligibility requirements under section 3.1. Thereafter, he or she shall be an inactive Participant and shall retain all the rights described under this Plan, except the right to elect any further deferrals of Bonus or Salary until he or she again becomes an active Participant. ARTICLE 4 DEFERRAL ELECTIONS 4.1 AMOUNT OF DEFERRAL. Prior to the beginning of each Plan Year, a Participant may elect to defer up to -- (a) 50 percent (in increments of 1 percent) of the Salary that would otherwise be payable to the Participant during the Plan Year; and (b) 100 percent (in increments of 1 percent) of the Bonus that would otherwise be payable to the Participant during the Plan Year. Each deferral of Salary and/or Bonus shall be credited to the Participant's Account as of the business day on which the cash would have otherwise been paid. If the closing of the Merger occurs in 1999, the deferral election filed for 1999 shall terminate with respect to Salary payable after such date unless the Company affirmatively elects to continue this Plan for new deferrals after such date. 4.2 CHANGE OR REVOCATION OF DEFERRAL. After the beginning of a Plan Year, a Participant may not increase, decrease or revoke the amount of Salary or Bonus deferred for that Plan Year under section 4.1. -5- ARTICLE 5 PARTICIPANTS' ACCOUNTS 5.1 INVESTMENT OF ACCOUNTS. With respect to each deferral election a Participant makes under Section 4.1, the Participant shall elect in writing to hypothetically deem to have the deferrals made on his or her behalf invested in any one or more of the Investment Funds in 1 percent increments. The account value for each amount deferred shall be determined based on the Investment Fund's value on the date the amount deferred would have otherwise been payable to the Participant. 5.2 INVESTMENT CHANGES FOR PREDECESSOR PLANS. With respect to account balances in each Predecessor Plan, if the valuation of any account is dependent upon the book value or fair market value of MidAmerican Energy Holdings Company common stock, or if earnings on an account are determined by the dividend rate on MidAmerican Energy Holdings Company common stock (other than a rate that has been fixed as of a certain date and is not subject to further change), each Participant who has such an account balance shall file an election form with the Committee prior to the closing date of the Merger, designating, pursuant to the procedures in section 5.1, the Investment Funds in which such account is deemed to be invested. To the extent the value of an account, as of the closing date of the Merger, is based on the value of MidAmerican Energy Holdings Company common stock, the value of each stock unit in any such account shall be deemed to be $27.15, plus any dividend paid to shareholders of MidAmerican Energy Holdings Company common stock through the closing date of the Merger. In any account based on a fixed value with crediting of interest only, but which varies in the interest rate credited from time to time, interest on the account shall be credited through date of closing of the Merger. Amounts converted to the Investment Funds as of the closing date of the Merger shall be converted based on the Investment Fund benchmark values on the date of closing. As to any Participant's account transferred from a Predecessor Plan with a fixed value and fixed interest rate credited to the account (i.e. debentures under the Iowa Resources Inc. Executive Deferred Compensation Plan), the Participant's account balance shall continue to reflect such fixed value and shall continue to be credited with the fixed interest rate, unless the Participant elects to have his or her account value related to such fixed investment converted to one or more of the Investment Funds pursuant to the procedure set forth above within the time frame specified above. -6- 5.3 CONTINGENCY OF MERGER. In the event the Merger does not take place, then with respect to amounts deferred for 1999, such amounts shall be reconverted, as of January 1, 1999, to the forms of deemed investments as existed in the MidAmerican Energy Company Executive Deferred Compensation Plan prior to the establishment of this Plan. In addition, with respect to investment changes for Predecessor Plans as provided in Section 5.2, in the event the Merger does not take place, the provisions of Section 5.2 shall become null and void and the account balances transferred to this Plan from the Predecessor Plans shall continue in the same form and deemed investments as in the Predecessor Plans. However, all other provisions of this Plan, including, but not limited to payment provisions in Article 6, shall apply to such accounts. 5.4 CHANGES IN INVESTMENTS. A Participant may change the hypothetical investment allocation in his or her account no more than once during any calendar quarter by filing an appropriate form with the Committee (or its designated administrative representative) specifying the change to be made. The change shall be processed within five (5) business days of receipt of the change request by the Committee. 5.5 VALUATION OF ACCOUNTS. (a) ALLOCATION OF EARNINGS AND LOSSES. A Participant's Account shall be adjusted as of each Valuation Date to reflect any gains or losses that would have been credited or debited to the Account if it had actually been invested in the manner described in section 5.1. Accounts where an investment change request has been received between these dates will be credited or charged for any investment gains or losses since the last Valuation Date through the effective date of the investment change. (b) CHARGES AGAINST ACCOUNT. Any payments made to a Participant or Beneficiary under Article 6 shall be charged against the Participant's Account. 5.6 FINANCING. The benefits under this Plan shall be paid out of the general assets of the Employer, except to the extent they are paid from the assets of a grantor trust established by an Employer to pay these benefits. 5.7 UNSECURED INTEREST. No Participant shall have any interest whatsoever in any specific asset of the Employer. To the extent that any person acquires a right to receive payments under this Plan, this right shall be no greater than the right of any unsecured general creditor of the Employer. 5.8 NONTRANSFERABILITY. In no event shall an Employer make any payments under this Plan to any assignee or creditor of a Participant or Beneficiary. Prior to the time of payment hereunder, no Participant or Beneficiary shall have any right by way of anticipation or otherwise to assign or otherwise dispose of any interest under this Plan, nor shall rights be assigned or transferred by operation of law. -7- ARTICLE 6 PAYMENT OF ACCOUNTS 6.1 PAYMENTS TO PARTICIPANTS.
