                            ESTABLISHMENT AND PURPOSE

1.1  BACKGROUND OF PLAN.  MidAmerican Energy Holdings Company presently
maintains a deferred compensation plan for its Board of Directors.

This restated Plan shall replace that Plan if the Merger,  as defined in Section
1.4 below closes in 1999,  and shall replace that Plan as of the closing date of
the Merger.

The Plan shall be maintained as an unfunded  plan of deferred  compensation  for
its Board of Directors.

1.2  PURPOSE OF PLAN.  The purpose of this Plan is to provide the Company's
Board of Directors with an additional way to defer portions of their Board of
Directors fees.

1.3  APPLICABILITY OF PLAN.  The provisions of this Plan are applicable to
members of the  Company's  Board of Directors who serve on the Board 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. This Plan shall not accept any deferrals with respect to any Director
fees payable after the closing date of the Merger.

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 Plan 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")),  the
accounts under the Predecessor  Plan are hereby merged into the Plan,  effective
as of the date of closing of the Merger.

                                    ARTICLE 4
                               DEFERRAL ELECTIONS

                             PARTICIPANTS' ACCOUNTS

5.1  INVESTMENT OF 1999 DEFERRALS.  With respect to each  deferral  election a
Participant  made  under  this Plan for 1999  prior to the  closing  date of the
Merger, the Participant shall elect in writing,

                                      -3-


prior to the closing  date of the  Merger,  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 paid.  This  investment  election
shall supersede and replace the investment election made by the Participant with
respect to amounts deferred for 1999 under the Plan prior to the closing date of
the Merger.

5.2  INVESTMENT CHANGES FOR PREDECESSOR PLANS.  With respect to account balances
in the  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, each Participant who has such
an account  balance shall file an election form with the Committee  prior to, or
within  fifteen (15) days after,  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.  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.

5.3  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.

5.4  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.

                                      -4-

     (b)  CHARGES AGAINST ACCOUNT. Any payments made to a Participant or
          Beneficiary  under  Article  6 shall be  charged  against  the
          Participant's Account.

5.5  FINANCING.  The  benefits  under this Plan shall be paid out of the general
assets of the  Company,  except to the extent they are paid from the assets of a
grantor trust established by the Company to pay these benefits.

5.6  UNSECURED INTEREST.  No Participant shall have any interest whatsoever in
any  specific  asset of the  Company.  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 Company.

5.7  NONTRANSFERABILITY.  In no event shall the Company 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.

                                    ARTICLE 6
                               PAYMENT OF ACCOUNTS

6.1  CONDITIONS ON RIGHT TO RECEIVE PAYMENT.  A Participant shall not be
entitled to payment of any deferred  compensation  from his or her account until
the  time  elected  by the  Participant  as set  forth on the  written  deferral
election form filed with the Corporate Secretary of the Company, or until his or
her death or permanent  disability,  whichever  occurs first.  The election form
shall  state the date the  payment  shall  commence  and the  period  over which
payment  shall  be  made.  The  Participant   may  elect  to  receive   deferred
compensation and accumulated  earnings thereon in his or her Account either in a
lump sum payment or in annual installments.  Once an election is filed, it shall
not be changed  except by approval of the Board of Directors of the Company.  If
annual installments are selected, each annual installment shall not be less than
an amount equal to the value of the account at the beginning of the Plan Year in
which  distribution  is to be  made  divided  by  the  life  expectancy  of  the
Participant at the beginning of such Plan Year (or the joint life  expectancy of
the  Participant  and  spouse  if  the  Participant  is  married).  Each  annual
installment  shall be made within  fifteen (15) days  following the first day of
each Plan Year.  If an election is made to receive a lump sum  payment,  payment
shall be made within  fifteen (15) days following the first day of the Plan Year
in which payment is to be made,  and the amount of the lump sum payment shall be
equal to the value of the account as of December 31 of the preceding  Plan Year.
Payment of a lump sum amount or any annual installment shall be made in cash.

                                      -5-

6.2  CHANGE IN ELECTION UNDER PREDECESSOR PLAN.  Except as provided below, with
respect to elections filed for deferred  amounts under a Predecessor  Plan, such
election as to method and timing of payment  shall  continue to be applicable to
the accounts  transferred  from a  Predecessor  Plan. A  Participant  may file a
revised  election  with respect to the account  transferred  from a  Predecessor
Plan.  The  revised  election  form shall  specify  the new timing and method of
payout (either lump sum or annual  installments).  If the new election serves to
accelerate  the payout of a lump sum or to elect a lump sum payment where annual
installments  had been previously  elected,  and if the new lump sum election is
for  payment to occur  within  three years of the date of closing of the Merger,
the value of the account  shall be reduced by 6% as of the new date  elected for
payout.  If the new election form does not  accelerate  payments to within three
years following the date of closing of the Merger, no reduction shall be made in
the  value of the  account  to be paid.  A change  may be made with  respect  to
revising the timing of payout of substantially equal annual installments as long
as the final annual payment does not occur any earlier than January 1, 2002. Any
new elections as to timing or method of payout must be made within  fifteen (15)
days following the closing date of the Merger.

6.3  PAYMENT IN THE EVENT OF DEATH.  In the event of the death of a  Participant
occurring  either before the  commencement of payment or before the full balance
of the  Participant's  account has been paid,  the unpaid balance in the Account
shall  be paid in a lump  sum to the  Participant's  designated  beneficiary  or
estate,  payment  shall be made within  thirty (30) days  following  the date of
death.  The value of the Account shall be based upon the value of the Investment
Funds in his or her account on the date of death (or on the  preceding  business
day, if date of death is not a business day).

                                    ARTICLE 7
                               GENERAL PROVISIONS

7.1  GENERAL PROVISIONS.

     (a)  UNFUNDED PLAN.

          (i)  This Plan is intended to be an unfunded plan maintained primarily
               to provide  benefits to a "select  group of  management or highly
               compensated employees" within the meaning of Section 201, 301 and
               401 of the Employee  Retirement  Income  Security Act of 1974, as
               amended  ("ERISA"),  and as  amended  from  time  to  time or any
               successor  thereto,  and,  therefore,  is further  intended to be
               exempt  from  the  provisions  of  Parts 2, 3 and 4 of

                                       -6-

               Title I of ERISA.  Accordingly,  the  Compensation  Committee may
               terminate  the  Plan  for any or all  Participants  in  order  to
               achieve  and  maintain  this  intended   result,   provided  that
               previously  accrued  benefits  hereunder  shall not be reduced or
               otherwise  adversely  affected without the written consent of the
               affected Participants.

          (ii) The  obligations  hereunder  shall at all times be unsecured  and
               payments with respect to any benefits hereunder shall be paid out
               of the general operating  revenue of the Company.  A trust may be
               established   to  provide   for  the   payment  of   benefits  to
               Participants  hereunder  as long as the  assets of such trust are
               subject to the claims of general  creditors  of the Company  with
               respect to the deferrals (and earnings thereon, if applicable).

     (b)  WITHHOLDING.  The Company shall have the right to require Participants
          to remit to the Company an amount sufficient to satisfy Federal, state
          and local tax withholding  requirements,  or to deduct from any or all
          payments made pursuant to the Plan amounts  sufficient to satisfy such
          withholding tax requirements.

     (c)  COSTS OF THE PLAN. All costs of  implementing  and  administering  the
          Plan shall be borne by the Company.

     (d)  NON-ALIENATION OF BENEFITS.  No right or benefit under this Plan shall
          be subject to  anticipation,  alienation,  sale,  assignment,  pledge,
          encumbrance, or charge, and any attempt to anticipate, alienate, sell,
          assign,  pledge,  encumber, or charge the same shall be void. No right
          or benefit  hereunder  shall in any manner be liable for or subject to
          the debts, contracts, liabilities, or claims of the person entitled to
          such benefit. If any Participant or designated  beneficiary  hereunder
          should  become  bankrupt  or attempt to  anticipate,  alienate,  sell,
          assign,  pledge,  encumber,  or charge any right or benefit hereunder,
          then  such  right  or  benefit   shall,   in  the  discretion  of  the
          Compensation Committee, cease, and in such event, the Company may hold
          or  apply  the  same  or any  part  thereof  for  the  benefit  of the
          Participant  or  the  designated  beneficiary,   his  or  her  spouse,
          children,  or other dependents,  or any of them, in such manner and in
          such proportion as the Compensation Committee may deem proper.

     (e)  SUCCESSORS.  All  obligations  of the Company  under the Plan shall be
          binding upon and inure to the benefit of any successor to the Company,
          whether  the  existence  of such  successor  is the direct or indirect
          result of a merger or  reorganization  involving  the  Company  or the
          purchase  or other

                                      -7-


          acquisition, of all or substantially all of the business or assets of
          the Company.

     (f)  AMENDMENT OR TERMINATION OF PLAN.

          (i)  The Board of  Directors  reserves  the right at any time and from
               time to time to amend,  suspend or terminate the Plan without the
               consent of any Participant or other person claiming a right under
               the Plan.

          (ii) Any  amendment or  termination  of this Plan shall not  adversely
               affect the rights of Participants or designated  beneficiaries to
               payments of amounts  credited to Participants in their Account at
               the time of such amendment or termination.

     (g)  SEPARABILITY.  If any term or  provision  of this Plan as presently in
          effect or as amended from time to time, or the application  thereof to
          any  payments  or  circumstances,  shall to any  extent be  invalid or
          unenforceable,  the remainder of the Plan, and the application of such
          term or provision to payments or circumstances  other than those as to
          which it is invalid or  unenforceable,  shall not be affected thereby,
          and each term or  provision of the Plan shall be valid and enforced to
          the fullest extent permitted by law.

     (h)  CONSTRUCTION.   The  provisions  of  this  Plan  shall  be  construed,
          administered and enforced according to the laws of the State of Iowa.

     (i)  TITLES.  The titles of the Articles  and Sections  herein are included
          for  convenience  of reference only and shall not be construed as part
          of this Plan,  or have any effect upon the  meaning of the  provisions
          hereof.

     (j)  IMPOSSIBILITY OF ACTION. In case it becomes impossible for the Company
          to perform any act under this Plan,  that act shall be preformed which
          in the  judgment of the Company  will most nearly carry out the intent
          and purposes of this Plan. All parties concerned shall be bound by any
          such acts performed under such conditions.

     (k)  AUTHORIZED OFFICERS.  Whenever the Company under the terms of the Plan
          is permitted  and  required to perform any act or matter or thing,  it
          shall  be done  and  performed  by a duly  authorized  officer  of the
          Company.

                                      -8-
