determined  that the  acquisition  of  MidAmerican  by  CalEnergy is in the best
interests of each of its companies'  stockholders and employees and, in the case
of MidAmerican, those customers and communities served by MidAmerican; and

     WHEREAS,  in  furtherance  thereof,  the Boards of Directors of  CalEnergy,
Reincorporation  Sub,  MidAmerican  and Merger Sub have  approved  the  business
combination transaction provided for in this Agreement, pursuant to which Merger

sale,  assignments,  assurances  or any other actions or things are necessary or

Corporation  its right,  title or  interest  in, to or under any of the  rights,

Merger or otherwise to carry out this  Agreement,  the officers and directors of
the Surviving  Corporation  shall be  authorized to execute and deliver,  in the
name and on behalf of either MidAmerican or Merger Sub, all such deeds, bills of
sale,  assignments  and assurances and to take and do, in the name and on behalf

     (a) Unless  otherwise  determined by CalEnergy prior to the Effective Time,
at the Effective Time the Articles of  Incorporation of Merger Sub, as in effect

of the Surviving  Corporation  until  thereafter  amended as provided by law and
such Articles of Incorporation.

     (b) The  By-Laws  of  Merger  Sub,  as in effect  immediately  prior to the
Effective  Time,  shall  be the  By-Laws  of  the  Surviving  Corporation  until
thereafter  amended as provided by law,  the  Articles of  Incorporation  of the
Surviving Corporation and such By-Laws.

                                   ARTICLE II.

                               TREATMENT OF SHARES

     Section 2.1. Conversion of Securities.  At the Effective Time, by virtue of
the Merger and without any action on the part of Merger Sub,  MidAmerican or the
holder of any of the following securities:

     (a) Each Share,  together with the associated purchase rights ("MidAmerican
Rights") under the  MidAmerican  Rights  Agreement (as defined in Section 5.18),
issued and outstanding  immediately  prior to the Effective Time (other than any
Shares to be canceled  pursuant to Section 2.1(b) and any Dissenting  Shares (as
defined in Section 2.2(a)) shall be canceled and  extinguished  and be converted
into the right to receive $27.15 (the "Per Share Amount") in cash payable to the
holder thereof, without interest, upon surrender of the certificate representing
such Share.  Throughout this  Agreement,  the term "Shares" refers to the Shares
together with the associated MidAmerican Rights.

     (b) Each Share held in the treasury of MidAmerican  and each Share owned by
Parent or any direct or indirect  Subsidiary  (as defined below) of Parent or of
MidAmerican  immediately  prior to the  Effective  Time  shall be  canceled  and
extinguished,  and no payment or other  consideration shall be made with respect
thereto.

     (c) Each  share of common  stock,  no par  value,  of Merger Sub issued and
outstanding  immediately prior to the Effective Time shall thereafter  represent
one validly issued,  fully paid and nonassessable  share of common stock, no par
value, of the Surviving Corporation.

     Section 2.2.  Dissenting Shares.

     (a)  Notwithstanding  any provision of this Agreement to the contrary,  any
Shares held by a holder who has demanded and  perfected his demand for appraisal
of his  Shares in  accordance  with  Section  1302 of the Iowa Act and as of the
Effective  Time has  neither  effectively  withdrawn  nor lost his right to such
appraisal  ("Dissenting  Shares"),  shall not be  converted  into or represent a
right to receive cash  pursuant to Section 2.1, but the holder  thereof shall be
entitled to only such rights in respect  thereof as are granted by Section  1302
of the Iowa Act.

     (b)  Notwithstanding  the provisions of subsection (a) of this Section,  if
any  holder of Shares who  demands  appraisal  of his Shares  under the Iowa Act
shall effectively withdraw or lose (through failure to perfect or otherwise) his
right to  appraisal,  then as of the  Effective  Time or the  occurrence of such
event,  whichever  later occurs,  such holder's  Shares shall  automatically  be
converted  into and  represent  only the right to receive  cash as  provided  in
Section 2.1(a),  without interest thereon,  upon surrender of the certificate or
certificates representing such Shares.

     (c)  MidAmerican  shall give  CalEnergy or Parent,  as the case may be, (i)
prompt notice of any written  demands for appraisal or payment of the fair value
of any Shares,  withdrawals of such demands,  and any other  instruments  served
pursuant to the Iowa Act received by  MidAmerican  and (ii) the  opportunity  to
direct all  negotiations  and proceedings  with respect to demands for appraisal
under the Iowa Act.  MidAmerican  shall not  voluntarily  make any payment  with
respect  to any  demands  for  appraisal  and shall not,  except  with the prior
written consent of CalEnergy, settle or offer to settle any such demands.

     Section 2.3.  Surrender of Shares; Stock Transfer Books.

     (a) Prior to the  Effective  Time,  MidAmerican  shall  designate a bank or
trust company to act as agent for the holders of Shares (the  "Exchange  Agent")
to receive the funds necessary to make the payments contemplated by Section 2.1.
At the Effective Time, Parent shall deposit, or cause to be deposited,  in trust
with the  Exchange  Agent for the  benefit of holders of Shares,  the  aggregate
consideration  to which such  holders  shall be entitled at the  Effective  Time
pursuant to Section 2.1.

     (b) Each holder of a certificate or  certificates  representing  any Shares
canceled upon the Merger  pursuant to Section  2.1(a) may  thereafter  surrender
such  certificate  or  certificates  to the  Exchange  Agent,  as agent for such
holder,  to effect the surrender of such  certificate  or  certificates  on such
holder's behalf for a period ending six months after the Effective Time.  Parent
agrees that promptly after the Effective Time it shall cause the distribution to
holders of record of Shares as of the Effective Time of appropriate materials to
facilitate such surrender.  Upon the surrender of certificates  representing the
Shares,  Parent  shall  cause  the  Exchange  Agent  to pay the  holder  of such
certificates  in  exchange  therefor  cash in an  amount  equal to the Per Share
Amount multiplied by the number of Shares represented by such certificate,  plus
the amount of dividends or other  distributions  with a record date prior to the
Effective Time, if any,  remaining unpaid with respect to the Shares represented
by  such  certificate   immediately  prior  to  the  Effective  Time.  Until  so
surrendered,   each  such  certificate  (other  than  certificates  representing
Dissenting  Shares and  certificates  representing  Shares canceled  pursuant to
Section  2.1(b)) shall  represent  solely the right to receive the aggregate Per
Share Amount relating thereto, subject, however, to Parent's obligation (if any)
to pay any dividends or make any other distributions with a record date prior to
the Effective  Time which may have been declared by MidAmerican on the shares of
MidAmerican  Common Stock in accordance  with the terms of this  Agreement on or
prior to the date of this  Agreement  and which remain  unpaid at the  Effective
Time.

     (c) If payment of cash in  respect  of  canceled  Shares is to be made to a
Person  other  than  the  Person  in whose  name a  surrendered  certificate  or
instrument  is  registered,  it shall be a condition  to such  payment  that the
certificate or instrument so surrendered  shall be properly endorsed or shall be
otherwise  in proper  form for  transfer  and that the  Person  requesting  such
payment shall have paid any transfer and other taxes  required by reason of such
payment in a name other than that of the registered holder of the certificate or
instrument  surrendered or shall have  established to the satisfaction of Parent
or the Exchange Agent that such tax either has been paid or is not payable.

     (d) At the Effective Time, the stock transfer books of MidAmerican shall be
closed and there shall not be any further registration of transfer of any shares
of capital stock  thereafter on the records of  MidAmerican.  From and after the
Effective Time, the holders of certificates  evidencing  ownership of the Shares
outstanding  immediately  prior to the  Effective  Time shall  cease to have any
rights with respect to such Shares,  except as otherwise  provided for herein or
by applicable  law. If, after the Effective  Time,  certificates  for Shares are
presented to the Surviving Corporation, they shall be canceled and exchanged for
cash as provided in Section  2.1(a).  No interest shall accrue or be paid on any
cash  payable  upon  the  surrender  of  a  certificate  or  certificates  which
immediately prior to the Effective Time represented outstanding Shares.

     (e) Promptly  following  the date which is six months  after the  Effective
Time,  the  Exchange  Agent  shall  deliver  to Parent all cash  (including  any
interest received with respect thereto), certificates and other documents in its
possession  relating to the transactions  contemplated  hereby, and the Exchange
Agent's  duties  shall  terminate.  Thereafter,  each  holder  of a  certificate
representing Shares (other than certificates  representing Dissenting Shares and
certificates  representing  Shares canceled pursuant to Section 2.1(b)) shall be
entitled to look to the Surviving  Corporation  (subject to applicable abandoned
property,  escheat  and similar  laws) only as general  creditors  thereof  with
respect to the  aggregate  Per Share Amount  payable upon due surrender of their
certificates,  without any interest or dividends  thereon.  Notwithstanding  the
foregoing,  neither  Parent,  the Surviving  Corporation  nor the Exchange Agent
shall be liable to any holder of a certificate  representing  Shares for the Per
Share Amount delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

     (f) The Per Share  Amount paid in the Merger  shall be net to the holder of
Shares in cash,  subject to reduction  only for any applicable  federal  back-up
withholding or, as set forth in Section 2.3(c),  stock transfer taxes payable by
such holder.

     Section 2.4. MidAmerican Option Plan.

     (a)  CalEnergy  or,  as the  case may be,  Parent  shall  take all  actions
necessary  to  provide  that,  upon  consummation  of  the  Merger,   each  then
outstanding  option to  purchase  shares of  MidAmerican  Common  Stock or stock
appreciation  right  representing  the right  (contingent  or other) to purchase
shares of MidAmerican Common Stock or, following the Merger, of shares of common
stock, no par value,  of Parent ("Parent Common Stock),  or grant of performance
shares  representing  the right  (contingent  or other)  to  purchase  shares of
MidAmerican  Common Stock or,  following the Merger,  of Parent Common Stock, or
other similar interest (collectively, the "MidAmerican Options") whether granted
under  MidAmerican's  1995  Long-Term  Incentive Plan (the  "MidAmerican  Option
Plan") or under any other plan or arrangement,  whether or not then  exercisable
or vested,  all of which,  together with the  applicable  exercise  prices,  are
disclosed  in Section  5.10(a) of the  MidAmerican  Disclosure  Schedule  (or as
otherwise  permitted  from and  after  the date of this  Agreement  pursuant  to
Section  6.1(c)) shall be assumed by Parent at the Effective Time (except in the
case of  performance  shares of  MidAmerican,  which  will be paid the Per Share
Amount at the Effective Time), and each such MidAmerican  Option shall become an
option to purchase the number of shares of Parent  Common  Stock  rounded to the
nearest whole number (a "MidAmerican  Substitute Option") equal to the number of
shares of MidAmerican Common Stock subject to such MidAmerican Option multiplied
by the number (the "Exchange Ratio") determined by dividing the Per Share Amount
by the CalEnergy  Share Price (as defined  below).  The "CalEnergy  Share Price"
shall be equal to the average of the  closing  prices of the common  stock,  par
value $0.0675 per share, of CalEnergy ("CalEnergy Common Stock), on the New York
Stock Exchange Composite  Transaction  Reporting System, as reported in The Wall
Street Journal, for the 20 trading days immediately preceding the second trading
day  prior  to the  Effective  Time.  The per  share  exercise  price  for  each
MidAmerican  Substitute  Option shall be the current exercise price per share of
MidAmerican  Common  Stock  divided by the  Exchange  Ratio  (rounded  up to the
nearest full cent),  and each MidAmerican  Substitute  Option otherwise shall be
subject,  in all material  respects,  to the other terms and  conditions  of the
original MidAmerican Option to which it relates.

     (b) Prior to the Effective Time, MidAmerican shall take such actions as are
necessary under applicable law and the applicable agreements and the MidAmerican
Option Plan to ensure that each outstanding  MidAmerican  Option shall, from and
after the Effective Time,  represent only the right to purchase,  upon exercise,
shares of Parent Common Stock.

     (c) As soon as  reasonably  practicable  after the Effective  Time,  Parent
shall cause to be included under a registration  statement on Form S-8 of Parent
all shares of Parent  Common Stock which are subject to  MidAmerican  Substitute
Options,  and shall maintain the  effectiveness of such  registration  statement
until all such MidAmerican  Substitute  Options have been exercised,  expired or
forfeited.

                                  ARTICLE III.

                                  THE CLOSING

     Section 3.1. Closing.  The closing of the Merger (the "Closing") shall take
place at the offices of Willkie Farr & Gallagher,  787 Seventh Avenue, New York,
New York,  10019 at 10:00  A.M.,  New York  time,  on the  second  business  day
immediately  following the date on which the last of the conditions set forth in
Article  VIII hereof is  fulfilled  or waived,  or at such other time,  date and

            REPRESENTATIONS AND WARRANTIES OF MAVERICK AND MERGER SUB

     CalEnergy  and Merger Sub hereby  represent and warrant to  MidAmerican  as

nature of its business or the ownership or leasing of its assets and  properties
makes such qualification  necessary other than in such  jurisdictions  where the
failure to so qualify  and be in good  standing,  when taken  together  with all
other such failures,  would not have a material  adverse effect on the business,
operations, properties, assets, condition (financial or other), prospects or the

applicable  environmental  law,  ordinance or  regulation)  of any  Governmental
Authority,  except for violations which individually or in the aggregate do not,

thereto for the year ended  December  31,  1997,  or which were  incurred  after

Section 5.10(b) of the MidAmerican Disclosure Schedule, (i) the current value of
all  accrued  benefits  under any  MidAmerican  Benefit  Plan which is a defined
benefit plan did not, as of the date of the most recent actuarial  valuation for

minimum funding  requirements  of Code Section 412, which actuarial  assumptions
and  calculations  have been  provided  to  CalEnergy  prior to the date of this

been  determined  by the  IRS to be so  qualified,  and,  to  the  knowledge  of
MidAmerican,  no circumstances exist that are reasonably expected by MidAmerican

respects in compliance with the terms thereof and all applicable laws, rules and
regulations  governing such plan, including,  without limitation,  ERISA and the
Code.  Each  MidAmerican  Benefit  Plan  intended to provide for the deferral of

tax benefits complies with the requirements of the applicable  provisions of the
Code or other laws,  rules and  regulations  required to provide such income tax
benefits.

and in the  aggregate,  there are no actions,  suits,  claims pending or, to the
knowledge of  MidAmerican,  threatened  and no event has  occurred,  and, to the
knowledge of MidAmerican, there exists no condition or set of circumstances that
could  subject  MidAmerican  or  any  of  the  MidAmerican  Subsidiaries  to any
liability  arising under the Code, ERISA or any other applicable law (including,
without  limitation,  any liability of any kind  whatsoever,  whether  direct or
indirect,  contingent,  inchoate or otherwise,  to any such plan or the PBGC, or
under any indemnity  agreement to which  MidAmerican  or any of the  MidAmerican
Subsidiaries is a party, in each such case, which liability,  individually or in

Adverse Effect.

benefits  payable to or on behalf of any employee or director after  termination
of employment or service,  as the case may be, other than elective  continuation
required  pursuant to Code Section 4980B or coverage which expires at the end of
the calendar month following such event.  Each such plan that is a "group health
plan" (as defined in Code Section 4980B(g)) has been operated in compliance with
Code Section 4980B at all times,  except for any non-compliance  that would not,
or insofar as reasonably can be determined could not, give rise to a MidAmerican
Material Adverse Effect.

true  and  correct  copy  of  each  collective  bargaining  agreement  to  which

consummation of any transaction  contemplated by this Agreement will not (either
alone or upon the  occurrence  of any  additional  or  further  acts or  events,
including,  without  limitation,  termination of  employment)  result in any (A)
payment (whether of severance pay or otherwise) becoming due from MidAmerican or
any of the MidAmerican Subsidiaries to any officer, employee, former employee or
director  thereof  or  to  the  trustee  under  any  "rabbi  trust"  or  similar
arrangement or (B) benefit being established or becoming accelerated,  vested or
payable under any MidAmerican  Benefit Plan and (ii) neither MidAmerican nor any
of the MidAmerican  Subsidiaries  is a party to (A) any management,  employment,

of MidAmerican,  as of the date hereof, there is no current union representation
question   involving   employees  of  MidAmerican  or  any  of  the  MidAmerican
Subsidiaries,  nor does  MidAmerican  know of any activity or  proceeding of any
labor organization (or representative thereof) or employee group to organize any
such  employees.  Except  as set forth in  Section  5.10(h)  of the  MidAmerican
Disclosure  Schedule,  (i)  there  is  no  unfair  labor  practice,   employment
discrimination or other complaint against  MidAmerican or any of the MidAmerican
Subsidiaries pending or, to the knowledge of MidAmerican,  threatened, which has
or could  reasonably be expected to have a MidAmerican  Material Adverse Effect,
(ii) there is no strike,  dispute,  slowdown,  work stoppage or lockout pending,
or,  to  the  knowledge  of  MidAmerican,   threatened,   against  or  involving
MidAmerican or any of the MidAmerican Subsidiaries which has or could reasonably
be expected to have, a MidAmerican Material Adverse Effect and (iii) there is no
proceeding, claim, suit, action or governmental investigation pending or, to the

may be  entitled to claim  indemnification  from  MidAmerican  pursuant to their
respective   articles  of  incorporation  or  by-laws  or  as  provided  in  the
Indemnification   Agreements  listed  in  Section  5.10(h)  of  the  MidAmerican
Disclosure  Schedule.  Except as set forth in Section 5.10(h) of the MidAmerican

no person has, to the knowledge of MidAmerican, asserted that MidAmerican or any
of the MidAmerican Subsidiaries is liable in any material amount for any arrears

foregoing.

     (i)  Parachute  Payments.  Section  5.10(i) of the  MidAmerican  Disclosure
Schedule  sets forth (1) the name of each  employee,  former  employee  or other
person  who is or was  providing  services  to  MidAmerican  or any  MidAmerican
Subsidiaries and who, in connection with the transactions contemplated with this
Agreement, will receive, or will or may become entitled to receive in the future
or upon termination of such person's employment, any payments (including without
limitation  accelerated  vesting of  MidAmerican  Options or other  equity-based
awards)  which could  reasonably  be expected to  constitute  "excess  parachute
payments"  with respect to such person within the meaning of Section 280G of the
Code ("Excess  Parachute  Payments"),  (2) with respect to each such person, the
maximum amount of Excess  Parachute  Payments which could reasonably be expected

who is  entitled  to receive a  "gross-up  payment"  in respect of excise  taxes

MidAmerican  or any  MidAmerican  Subsidiaries  will fail to be  deductible  for
Federal  income tax  purposes by reason of the  deduction  limit  imposed  under
Section  162(m) of the  Code.  Section  5.10(j)  of the  MidAmerican  Disclosure
Schedule  sets  forth  the  name of each  executive  officer  who  will  receive
compensation  which may not be fully  deductible by reason of the application of
Section  162(m),  and a  reasonable  estimate of the amount of such  potentially

     Section 5.11. Environmental Protection.

     (a)  Compliance.  Except as set forth in Section 5.11(a) of the MidAmerican
Disclosure Schedule,  MidAmerican and each of the MidAmerican  Subsidiaries and,
to  the  knowledge  of  MidAmerican,  the  MidAmerican  Joint  Ventures  are  in
compliance with all applicable Environmental Laws except where the failure to so
comply  would  not have a  MidAmerican  Material  Adverse  Effect,  and  neither
MidAmerican   nor  any  of  the  MidAmerican   Subsidiaries   has  received  any

alleges  that  MidAmerican  or  any  of  the  MidAmerican  Subsidiaries  or  the
MidAmerican   Joint  Ventures  is  not  in  such   compliance   with  applicable
Environmental  Laws.  To the  knowledge  of  MidAmerican,  compliance  with  all
applicable  Environmental  Laws will not require  MidAmerican or any MidAmerican
Subsidiary or, to the knowledge of MidAmerican, any MidAmerican Joint Venture to
incur costs beyond that currently  budgeted in the five MidAmerican fiscal years
beginning  with January 1, 1998 (as disclosed to CalEnergy  prior to the date of
this  Agreement)  that will be  reasonably  likely  to  result in a  MidAmerican

Effect,  and all such  Environmental  Permits  are in good  standing  or,  where
applicable,  a renewal  application  has been timely filed and is pending agency
approval, and MidAmerican and the MidAmerican Subsidiaries and, to the knowledge
of MidAmerican,  the MidAmerican Joint Ventures are in compliance with all terms
and conditions of all  Environmental  Permits  necessary for the construction of
its facilities or the conduct of its operations,  except where the failure to so

MidAmerican Disclosure Schedule, there is no Environmental Claim pending (or, to
the knowledge of MidAmerican,  threatened) (A) against MidAmerican or any of the
MidAmerican  Subsidiaries  or,  to  the  knowledge  of  MidAmerican,  any of the
MidAmerican  Joint Ventures,  (B) to the knowledge of  MidAmerican,  against any
person or entity whose liability for any Environmental  Claim MidAmerican or any
of the MidAmerican Subsidiaries or, to the knowledge of MidAmerican,  any of the
MidAmerican   Joint  Ventures  has  or  may  have  retained  or  assumed  either
contractually  or by  operation  of law,  or (C)  against  any real or  personal
property or operations which MidAmerican or any of the MidAmerican  Subsidiaries
or, to the knowledge of MidAmerican, any of the MidAmerican Joint Ventures owns,
leases or manages,  in whole or in part, which, if adversely  determined,  would
have, in the aggregate, a MidAmerican Material Adverse Effect.

     (d)  Releases.  Except as set forth in Section  5.11(d) of the  MidAmerican
Disclosure  Schedule,  MidAmerican  has  no  knowledge  of any  Releases  of any
Hazardous  Material  that  would be  reasonably  likely to form the basis of any
Environmental Claim against  MidAmerican or any of the MidAmerican  Subsidiaries
or the  MidAmerican  Joint  Ventures,  or  against  any  person or entity  whose
liability for any  Environmental  Claim  MidAmerican  or any of the  MidAmerican
Subsidiaries  or the  MidAmerican  Joint  Ventures  has or may have  retained or
assumed either contractually or by operation of law except for any Environmental
Claim which would not have, in the  aggregate,  a MidAmerican  Material  Adverse
Effect.

     (e) Predecessors. Except as set forth in Section 5.11(e) of the MidAmerican
Disclosure  Schedule,   MidAmerican  has  no  knowledge,  with  respect  to  any
predecessor  of  MidAmerican  or  any  of the  MidAmerican  Subsidiaries  or the
MidAmerican Joint Ventures, of any Environmental Claim pending or threatened, or
of any Release of Hazardous  Materials  that would be reasonably  likely to form
the basis of any  Environmental  Claim,  which,  if determined  adversely  could
reasonably be expected to require payments of $20 million or more or which could
reasonably be expected to have a MidAmerican Material Adverse Effect.

     (f)  Disclosure.  MidAmerican  has  disclosed in writing to  CalEnergy  all
material  facts  which  MidAmerican  reasonably  believes  form the  basis of an
Environmental  Claim  which could have a  MidAmerican  Material  Adverse  Effect
arising from (i) the cost of MidAmerican pollution control equipment (including,
without  limitation,  upgrades and other  modifications  to existing  equipment)
currently required or reasonably contemplated to be required in the future, (ii)
current  remediation  costs or costs to  MidAmerican  or any of the  MidAmerican
Subsidiaries  for  remediation  reasonably  contemplated  to be  required in the
future or (iii) any other environmental  matter affecting  MidAmerican or any of
the MidAmerican Subsidiaries.

     (g) Cost Estimates. To MidAmerican's knowledge, no environmental matter set
forth in the  MidAmerican  SEC Reports or the  MidAmerican  Disclosure  Schedule
could  reasonably  be  expected  to exceed the cost  estimates  provided  in the
MidAmerican SEC Reports by an amount that individually or in the aggregate could
reasonably be expected to have a MidAmerican Material Adverse Effect.

     Section 5.12. Regulation as a Utility.  MidAmerican Utility is regulated as
a public utility by the FERC and in the States of Illinois,  Iowa,  Nebraska and
South  Dakota  and in no other  state.  Except  as set  forth  in the  preceding

defined in the 1935 Act) of  MidAmerican  is subject to  regulation  as a public

     Section 5.13. Vote Required.  The approval of the Merger by the affirmative
vote of a majority of the votes  entitled  to be cast by holders of  MidAmerican
Common Stock (the "MidAmerican  Stockholders' Approval") is the only vote of the
holders of any class or series of the capital stock of MidAmerican or any of the
MidAmerican  Subsidiaries required to approve this Agreement, the Merger and the
other transactions contemplated hereby.

     Section  5.14.  Insurance.  Except  as set  forth  in  Section  5.14 of the
MidAmerican  Disclosure  Schedule,  MidAmerican  and  each  of  the  MidAmerican

financially  responsible  insurers in such  amounts  and against  such risks and
losses as are customary in all material  respects for companies  conducting  the
business as conducted by MidAmerican  and the  MidAmerican  Subsidiaries  during
such time period.  Neither  MidAmerican nor any of the MidAmerican  Subsidiaries
has  received  any notice of  cancellation  or  termination  with respect to any
material insurance policy of MidAmerican or any of the MidAmerican Subsidiaries.
The insurance  policies of MidAmerican and each of the MidAmerican  Subsidiaries
are valid and enforceable policies in all material respects.

     Section 5.15.  Opinion of Financial  Advisor.  MidAmerican has obtained the
opinion of Warburg  Dillon Read & Co.,  LLC ("Dillon  Read"),  dated the date of
this Agreement, to the effect that, as of the date thereof, the Per Share Amount

fair from a financial point of view to the holders of MidAmerican Common Stock.

     Section 5.16. Brokers.  No broker,  finder or investment banker (other than

the  business  combination  provisions  of  Section  1109 of the Iowa Act or any
similar  provisions of the Iowa Act, the articles of incorporation or by-laws of
MidAmerican  are applicable to the  transactions  contemplated by this Agreement
because  such  provisions  do not apply by their terms or because  any  required
approvals of the Board of Directors of MidAmerican have been obtained.

Agreement,  MidAmerican  has  delivered to CalEnergy  and its counsel a true and

partnership,  association or other business organization or division thereof, or
otherwise  acquire or agree to acquire any assets (other than  equipment,  fuel,
supplies and similar  items or for capital  expenditures,  in each case,  in the
ordinary course of business consistent with past practice);  provided,  however,
that notwithstanding the above,  CalEnergy or any of the CalEnergy  Subsidiaries

indemnity or other  agreement to maintain any financial  statement  condition of
another Person or enter into any  arrangement  having the economic effect of any

with  investments or  acquisitions  permitted by Section 6.2(a) or in connection
with the financing of the transactions contemplated hereby.

MidAmerican  or Parent or any  Subsidiary  of Parent to claim an exemption as of
right  under  Rule 2 of the  1935 Act or that  would  subject  CalEnergy  or any
CalEnergy  Subsidiary  to  regulation  under such  Act(other  than under Section

     Section 7.5. Directors' and Officers' Indemnification.

     (a)  Indemnification.  From and after the Effective Time,  Parent shall, to
the fullest extent not prohibited by applicable law, indemnify,  defend and hold
harmless  each  person  who is now,  or has been at any  time  prior to the date
hereof,  or who becomes prior to the  Effective  Time, an officer or director of
any of the parties hereto (each an  "Indemnified  Party" and  collectively,  the
"Indemnified  Parties")  against  all  losses,  expenses  (including  reasonable
attorney's fees and expenses), claims, damages or liabilities or, subject to the
proviso of the next succeeding sentence, amounts paid in settlement, arising out
of actions or omissions occurring at or prior to the Effective Time that are, in
whole or in part, based on or arising out of the fact that such person is or was
a  director  or  officer  of such  party  arising  out of or  pertaining  to the
transactions contemplated by this Agreement (the "Indemnified Liabilities").  In
the event of any such loss, expense,  claim, damage or liability (whether or not
arising prior to the Effective  Time),  (i) Parent shall pay the reasonable fees
and expenses of counsel for the Indemnified  Parties  selected by Parent,  which
counsel  may also  serve  as  counsel  to  Parent  and  which  counsel  shall be
reasonably  satisfactory to the Indemnified  Parties (which consent shall not be
unreasonably  withheld),  promptly  after  statements  therefor are received and
otherwise  advance to such  Indemnified  Party  upon  request  reimbursement  of
documented  expenses  reasonably  incurred,  in either  case to the  extent  not
prohibited  by the Iowa Act,  (ii) Parent will  cooperate  in the defense of any
such  matter and (iii) any  determination  required  to be made with  respect to
whether an  Indemnified  Party's  conduct  complies with the standards set forth
under the Iowa Act and the articles of  incorporation  or by-laws of MidAmerican
shall be made by  independent  counsel  mutually  acceptable  to Parent  and the
Indemnified Party (the "Independent  Counsel");  provided,  however, that Parent
shall not be liable for any  settlement  effected  without its  written  consent
(which consent shall not be unreasonably withheld). The Indemnified Parties as a
group may retain only one law firm with respect to each related matter except to
the extent there is, in the written  opinion of the Independent  Counsel,  under
applicable  standards of  professional  conduct,  a conflict on any  significant
issue  between  positions of such  Indemnified  Party and any other  Indemnified
Party or Indemnified Parties.

     (b) Insurance.  For a period of six years after the Effective Time,  Parent
shall cause to be  maintained  in effect  policies of  directors'  and officers'
liability  insurance  maintained  by  MidAmerican;  provided,  that  Parent  may
substitute therefor policies of at least the same coverage containing terms that
are no  less  advantageous  with  respect  to  matters  occurring  prior  to the
Effective Time to the extent such liability insurance can be maintained annually
at a cost to Parent not greater than 200 percent of the current annual  premiums
for such directors' and officers'  liability  insurance,  which existing premium
costs are disclosed on Schedule 7.5(b) of the MidAmerican  Disclosure  Schedule;
provided, further, that if such insurance cannot be so maintained or obtained at
such  cost,  Parent  shall  maintain  or  obtain as much of such  insurance  for
MidAmerican  as can be so  maintained or obtained at a cost equal to 200 percent
of the current annual  premiums of MidAmerican  for its directors' and officers'
liability insurance.

     (c) Successors. In the event Parent or any of its successors or assigns (i)
consolidates with or merges into any other person or entity and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii)  transfers all or  substantially  all of its  properties  and assets to any
person or entity,  then and in either such case, proper provisions shall be made
so that the  successors and assigns of Parent shall assume the  obligations  set
forth in this Section 7.5.

     (d) Survival of  Indemnification.  To the fullest  extent not prohibited by
law, from and after the Effective Time, all rights to  indemnification as of the
date  hereof  in favor of the  employees,  agents,  directors  and  officers  of
CalEnergy,  MidAmerican and their respective  Subsidiaries with respect to their
activities as such prior to the Effective Time, as provided in their  respective
articles  of  incorporation  and  by-laws in effect on the date  thereof,  shall

an integral part of this Agreement and to modify the respective representations,
warranties,  covenants or agreements of the parties hereto  contained  herein to
the  extent  that such  representations,  warranties,  covenants  or  agreements
expressly refer to the Disclosure Schedules.  Anything to the contrary contained
herein or in the Disclosure Schedules  notwithstanding,  any and all statements,
representations, warranties or disclosures set forth in the Disclosure Schedules
delivered  on or before the date hereof shall be deemed to have been made on and
as of the date hereof. From time to time prior to the Closing, the parties shall
promptly  supplement  or amend the  Disclosure  Schedules  with  respect  to any
matter,  condition  or  occurrence  hereafter  arising  which,  if  existing  or
occurring  at the date of this  Agreement,  would have been  required  to be set
forth or described in the Disclosure Schedules. No supplement or amendment shall
be deemed to cure any  breach of any  representation  or  warranty  made in this
Agreement or have any effect for the purpose of determining  satisfaction of the
conditions set forth in Section 8.2(b) or Section 8.3(b).

     Section  7.7.  Public  Announcements.  Subject to each  party's  disclosure
obligations  imposed  by law  or  regulation,  CalEnergy  and  MidAmerican  will
cooperate  with  each  other in the  development  and  distribution  of all news
releases and other public information disclosures with respect to this Agreement
or any of the  transactions  contemplated  hereby and shall not issue any public
announcement  or statement with respect hereto or thereto without the consent of
the other party  (which  consent  shall not be  unreasonably  withheld and which
decision regarding consent shall be made as soon as reasonably practicable).

     Section 7.8. No Solicitations.  From and after the date hereof,  each party
hereto  will  not,  and will  not  authorize  or  permit  any of its  respective
Representatives to, directly or indirectly,  (i) solicit,  initiate or encourage
(including  by way of  furnishing  information)  or take  any  other  action  to
facilitate any inquiries or the making of any proposal which  constitutes or may
reasonably be expected to lead to an  Acquisition  Proposal (as defined  below),
(ii) enter into any agreement with respect to any Acquisition  Proposal or (iii)
in  the  event  of  an  unsolicited  written  Acquisition  Proposal,  engage  in
negotiations  or  discussions  with, or provide any  information or data to, any
Person  (other  than  to  the  parties  hereto,   any  of  their  affiliates  or
Representatives  and except for information  which has been previously  publicly
disseminated  by the parties)  relating to any Acquisition  Proposal;  provided,
however,  that  nothing  contained  in this  Section 7.8 or any other  provision
hereof shall  prohibit such party or its Board of Directors  from (i) taking and
disclosing  to its  stockholders  a  position  with  respect  to a tender  or an
exchange  offer by a third party  pursuant to Rules 14D-9 and 14e-2  promulgated
under the Exchange Act or (ii) making such disclosure to its stockholders as, in
good faith  judgment  of its Board of  Directors,  after  receiving  advice from
outside counsel, is required under applicable law.

     Without limiting the foregoing,  it is understood that any violation of the
restrictions set forth in the preceding sentence by an executive officer of such
party or any investment banker,  attorney or other Representative of such party,
whether  or not such  person is  purporting  to act on  behalf of such  party or
otherwise,  shall be deemed to be a breach of this  Section  7.8 by such  party.
Notwithstanding  any other  provision  hereof,  each party hereto may (i) at any
time  prior  to the time its  stockholders  shall  have  voted to  approve  this
Agreement, engage in discussions or negotiations with a third party who (without
any solicitation, initiation, encouragement, discussion or negotiation, directly
or  indirectly,  by or with  such  party or its  Representatives  after the date
hereof) seeks to initiate such  discussions or negotiations and may furnish such
third party information  concerning such party and its business,  properties and
assets  if, and only to the extent  that,  (A)(x) in the case of an  Acquisition
Proposal for MidAmerican, the third party has first made an Acquisition Proposal
that is financially superior to the Merger, (y) the third party has demonstrated
that financing for the Acquisition  Proposal is reasonably likely to be obtained
(as  determined  in good faith in each case by such  party's  Board of Directors
after  consultation with its financial  advisors) and (z) its Board of Directors
shall have concluded in good faith, after considering  applicable  provisions of
state law and on the basis of a  written  opinion  of  outside  counsel,  that a
failure to do so could  reasonably  be  expected to  constitute  a breach by its
Board of Directors of its fiduciary duties to its stockholders  under applicable
law and (B) prior to furnishing such information to or entering into discussions
or  negotiations  with such  person or entity,  such party (x)  provides  prompt
notice to the other party to the effect that it is furnishing  information to or
entering into  discussions  or  negotiations  with such person or entity and (y)
receives  from sch person an executed  confidentiality  agreement in  reasonably
customary form,  together with its written  acknowledgment  and agreement to pay
the  termination  and other  fees set forth in Section  9.3 if such  Acquisition
Proposal is consummated or any other  Acquisition  Proposal is consummated  with
such party or any of its affiliates, and (ii) comply with Rule 14e-2 promulgated
under the  Exchange  Act with regard to a tender or exchange  offer.  Each party
shall  immediately  cease and terminate any existing  solicitation,  initiation,
encouragement,  activity,  discussion or negotiation with any parties  conducted
heretofore by such party or its  Representatives  with respect to the foregoing.
Each party shall notify the other party hereto orally and in writing of any such
inquiries,  offers or proposals  (including,  without limitation,  the terms and
conditions  of any such  proposal  and the  identity  of the person  making it),
within 24 hours of the receipt thereof,  shall keep such other party informed of
the status and details of any such  inquiry,  offer or proposal,  and shall give
such other party five days'  advance  notice of any agreement to be entered into
with or any information to be supplied to any person making such inquiry,  offer
or proposal.

     The term "Acquisition  Proposal" shall mean a proposal or offer (other than
by another party hereto) for a tender or exchange offer,  merger,  consolidation
or other business combination  involving the party or any material Subsidiary of
the party or any proposal to acquire in any manner a substantial equity interest
in or a  substantial  portion  of the  assets  of  the  party  or  any  material
Subsidiary  of the  party,  other  than the  transactions  contemplated  by this
Agreement and except for  arrangements  made by CalEnergy in connection with the
financing of and the consummation of the transactions contemplated hereby.

collective  bargaining  agreements  and  commitments of the parties prior to the
date hereof  which apply to any current or former  employee or current or former
director of the parties hereto; provided,  however, that this undertaking is not

     Section 9.3. Termination Fee; Expenses.

     (a) Termination  Fee. If this Agreement (i) is terminated at such time that
this  Agreement is  terminable  pursuant to one of Section  9.1(g)(i) or Section
9.1(h)(i) (other than in circumstances  described in Section 9.3(c)) but not the
other  (provided,  that, for purposes of this Section 9.3 only,  representations
and  warranties  made by  MidAmerican  with  respect to each of the Quad  Cities
Station nuclear generation facility and the Ottumwa Unit coal burning generation
facility  shall  be  deemed  to be made  to  MidAmerican's  knowledge),  (ii) is
terminated  pursuant to Section  9.1(e) or Section 9.1(f) or (iii) is terminated
by  MidAmerican  pursuant to Section 9.1(b) at any time on or after December 31,
1999 when the only  approval  required by Section  8.1(c) which has not yet been
obtained is the  CalEnergy  Required  Statutory  Approval  described  in Section
4.4(c)(ii) of the CalEnergy  Disclosure Schedule and the other conditions to the
consummation of the transactions contemplated by this Agreement are then capable
of being  satisfied,  then (A) in the event of such a  termination  pursuant  to
Section 9.1(f) or Section 9.1(g)(i), MidAmerican shall pay to CalEnergy, and (B)
in the event of such a termination pursuant to Section 9.1(e), Section 9.1(h)(i)
or Section 9.1(b),  CalEnergy shall pay to MidAmerican,  promptly (but not later
than five  business  days  after such  notice is  received  pursuant  to Section
9.1(g)(i),  Section  9.1(h)(i) or Section 9.1(b) or is given pursuant to Section
9.1(e) or Section  9.1(f)) an amount equal to $35 million in cash if required to
be paid  by  CalEnergy  and  $35  million  in  cash  if  required  to be paid by
MidAmerican,  plus in  each  case  cash in an  amount  equal  to all  documented
out-of-pocket expenses and fees incurred by the other party (including,  without
limitation,  fees and  expenses  payable  to all legal,  accounting,  financial,
public relations and other  professional  advisors arising out of, in connection
with  or  related  to  the  Merger  or the  transactions  contemplated  by  this
Agreement) not in excess of $10 million.

     (b) Additional Termination Fees. If (i) this Agreement (w) is terminated by
any party  pursuant  to Section  9.1(e) or  Section  9.1(f),  (x) is  terminated
following a failure of the stockholders of MidAmerican or CalEnergy to grant the
necessary approvals described in Section 4.13 or Section 5.13, (y) is terminated
as a result of such party's  material breach of Section 7.4 or (z) is terminated
pursuant to Section  9.1(g)(i) or Section  9.1(h)(i) as a result of such party's
breach, and (ii) at the time of such termination or prior to the meeting of such
party's  stockholders there shall have been an Acquisition  Proposal  involving,
such party or its  affiliates  which at the time of such  termination  or of the
meeting of such  party's  stockholders  shall not have been (x) rejected by such
party and its Board of Directors and (y) withdrawn by the  third-party and (iii)
within two years of any such  termination  described  in clause  (i) above,  the
party or its affiliate which is the target of the Acquisition  Proposal ("Target
Party")  becomes a subsidiary or part of such offeror or a subsidiary or part of
an affiliate of such offeror, or merges with or into the offeror or a subsidiary
or affiliate of the offeror or enters into a definitive  agreement to consummate
an Acquisition Proposal with such offeror or affiliate thereof,  then (A) in the
event  MidAmerican  or one of its  affiliates is the Target  Party,  MidAmerican
shall pay to CalEnergy and (B) in the event  CalEnergy or one of its  affiliates
is the Target Party,  CalEnergy shall pay to MidAmerican,  at the closing of the
transaction  (and as a condition  to the  closing)  in which such  Target  Party
becomes  such a  subsidiary  or part of such other person or the closing of such
Acquisition Proposal occurs, an additional  termination fee equal to $60 million
in cash if required to be paid by CalEnergy  and $60 million in cash if required
to be paid by MidAmerican.

     (c) If this  Agreement is terminated by  MidAmerican,  by written notice to
CalEnergy,  due to the failure of CalEnergy to deliver the amount of cash to the
Exchange Agent required pursuant to Section 2.3(a) at a time when all conditions
to CalEnergy's  obligation to close have been  satisfied or otherwise  waived in
writing by CalEnergy,  then CalEnergy shall pay to MidAmerican a termination fee
of $60 million; provided,  however, that CalEnergy shall have no liability under
this Section 9.3(c) (or for any breach of covenant  pursuant to Section  9.3(a))
as a  result  of such  failure  if such  failure  is the  direct  result  of the
inability of CalEnergy to finance the  transaction  because of the occurrence of
any  significant  disruptions or material  adverse changes (i) in the market for
new issues of senior debt securities,  credit facilities or common, preferred or
equity- linked securities by a company having financial  characteristics similar
to those of CalEnergy or a holding company for MidAmerican,  respectively, as of
the date of this  Agreement,  or (ii) in the  financial  or  capital  markets in
general   which  make  it   impracticable   for  a  company   having   financial
characteristics  similar  to  those  of  CalEnergy  or  a  holding  company  for
MidAmerican,  respectively,  as of the  date of this  Agreement,  to  finance  a
transaction  of  the  size  and  nature  as  that   contemplated   hereunder  on
commercially  reasonable  financing  terms that are  available as of the date of
such financing.

     (d)  Expenses.  The parties  agree that the  agreements  contained  in this
Section  9.3 are an  integral  part  of the  transactions  contemplated  by this
Agreement and constitute  liquidated damages and not a penalty.  Notwithstanding
anything to the  contrary  contained  in this Section 9.3, if one party fails to
promptly  pay to the other any fee or expense  due under this  Section  9.3,  in
addition to any amounts paid or payable pursuant to such Section, the defaulting
party shall pay the costs and expenses  (including  legal fees and  expenses) in
connection  with any action,  including the filing of any lawsuit or other legal
action,  taken to collect  payment,  together with interest on the amount of any
unpaid fee at the publicly announced prime rate of Citibank,  N.A. from the date
such fee was required to be paid.

     (e) Limitation Of Fees.  Notwithstanding  anything  herein to the contrary,
the aggregate amount payable by MidAmerican  pursuant to Sections 9.3(a) and (b)
and (c) shall not  exceed  $95  million  and the  aggregate  amount  payable  by
CalEnergy pursuant to Sections 9.3(a), (b) and (c) shall not exceed $95 million,
in each case, plus expenses, as provided in Section 9.3(a).

     Section  9.4.  Amendment.  This  Agreement  may be amended by the Boards of
Directors of the parties hereto,  at any time before or after approval hereof by
the  stockholders  of MidAmerican and CalEnergy and prior to the Effective Time,
but after such  approvals,  no such amendment  shall (a) alter or change the Per
Share  Amount  under  Article  II or (b)  alter or  change  any of the terms and
conditions of this Agreement if any of the  alterations or changes,  alone or in
the  aggregate,  would  materially  adversely  affect  the  rights of holders of
MidAmerican  Common Stock or CalEnergy  Common Stock,  except for alterations or
changes that could otherwise be adopted by the Board of Directors of MidAmerican
or CalEnergy, without the further approval of such stockholders,  as applicable.
This  Agreement may not be amended  except by an instrument in writing signed on
behalf of each of the parties hereto.

     Section 9.5.  Waiver.  At any time prior to the Effective Time, the parties
hereto may (a) extend the time for the  performance of any of the obligations or
other  acts of the other  parties  hereto,  (b) waive  any  inaccuracies  in the
representations  and warranties  contained  herein or in any document  delivered
pursuant  hereto  and  (c)  waive  compliance  with  any  of the  agreements  or
conditions  contained  herein,  to the extent  permitted by applicable  law. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid if set forth in an instrument in writing signed on behalf of such party.

agreement and supersedes all other prior  agreements  and  understandings,  both
written and oral, among the parties, or any of them, with respect to the subject
matter  hereof  (other  than the  Confidentiality  Agreement),  (b) shall not be
assigned  by  operation  of law or  otherwise  and (c) shall be  governed by and
construed in  accordance  with the laws of the State of Delaware  applicable  to
contracts  executed in and to be fully  performed in such State,  without giving
effect to its conflicts of law rules or principles  and except to the extent the
provisions of this Agreement (including the documents or instruments referred to
herein) are expressly governed by or derive their authority from the Iowa Act.

     Section 10.5. Interpretation. When a reference is made in this Agreement to
Sections or Exhibits,  such  reference  shall be to a Section or Exhibit of this
Agreement,  respectively,  unless otherwise indicated. The table of contents and
headings  contained in this Agreement are for reference  purposes only and shall
not affect in any way the meaning or interpretation of this Agreement.  Whenever
the words "include," "includes" or "including" are used in this Agreement,  they
shall be deemed to be followed by the words "without limitation."

     Section 10.6.  Counterparts;  Effect. This Agreement may be executed in one
or more counterparts,  each of which shall be deemed to be an original,  but all
of which shall constitute one and the same agreement.

     Section 10.7. Enforcement.  The parties agree that irreparable damage would
occur  in the  event  that  any of the  provisions  of this  Agreement  were not
performed in accordance with their specific terms or were otherwise breached. It
is  accordingly  agreed that the parties  shall be entitled to an  injunction or
injunctions to prevent  breaches of this  Agreement and to enforce  specifically
the terms and  provisions  of this  Agreement in any court of the United  States
located  in the  State of New York or in New York  state  court,  this  being in
addition to any other remedy to which they are entitled at law or in equity.  In
addition,  each of the  parties  hereto  (a)  consents  to submit  itself to the
personal  jurisdiction  of any federal court located in the State of New York or
any New York state court in the event any dispute  arises out of this  Agreement
or any of the  transactions  contemplated by this Agreement,  (b) agrees that it
will not attempt to deny such personal  jurisdiction  by motion or other request
for leave from any such  court and (c) agrees  that it will not bring any action
relating  to this  Agreement  or any of the  transactions  contemplated  by this
Agreement in any court other than a federal or state court  sitting in the State
of New York.

     Section 10.8. Parties in Interest. This Agreement shall be binding upon and
inure  solely to the  benefit of each party  hereto,  and,  except for rights of
Indemnified  Parties as set forth in  Section  7.5,  nothing in this  Agreement,
express or implied,  is  intended to confer upon any other  person any rights or
remedies of any nature whatsoever under or by reason of this Agreement.

     Section  10.9.  Further  Assurances.  Each party will  execute such further
documents and  instruments  and take such further  actions as may  reasonably be
requested  by any  other  party  in  order  to  consummate  the  Merger  and the
Reincorporation  in accordance with the terms hereof.  CalEnergy and MidAmerican
expressly  acknowledge that,  although it is their current intention to effect a
business   combination   among  themselves  by  means  of  the  Merger  and  the
Reincorporation,   it  may  be  preferable  for  CalEnergy  and  MidAmerican  to
effectuate such a business  combination by means of an alternative  structure in
light of the  conditions  set  forth in  Sections  8.1(c)  and  8.3(d)  and (f).
Accordingly,  if the only  conditions to the parties'  obligations to consummate
the Merger and the Reincorporation which are not satisfied or waived are receipt
of  CalEnergy  Required  Consents,   CalEnergy  Required  Statutory   Approvals,
MidAmerican Required Consents and MidAmerican Required Statutory Approvals that,
in the  reasonable  judgment  of  MidAmerican  or  CalEnergy,  would be rendered
unnecessary by adoption of an alternative structure that otherwise substantially
preserves for CalEnergy and MidAmerican the economic  benefits of the Merger and
the Reincorporation,  MidAmerican or CalEnergy, as the case may be, shall notify
the other of such  judgment  no later than 5:00 p.m.  Central  Time on March 31,
1999 and  thereafter  the  parties  shall use  their  best  efforts  to effect a
business  combination  among  themselves by means of a structure  other than the
Merger and the Reincorporation that so preserves such benefits;  provided,  that
all  material  third party and  Governmental  Authority  declarations,  filings,
registrations, notices, authorizations,  consents or approvals necessary for the
effectuation of such alternative  business  combination shall have been obtained
and all other  conditions to the parties'  obligations  to consummate the Merger
and the Reincorporation,  as applied to such alternative  business  combination,
shall have been satisfied or waived.

     Section 10.10.  Waiver Of Jury Trial.  Each party to this Agreement waives,
to the fullest  extent  permitted by applicable  law, any right it may have to a
trial by jury in respect of any  action,  suit or  proceeding  arising out of or
relating to this Agreement.

     Section 10.11.  Certain  Definitions.  The term  "affiliate,"  except where
otherwise defined herein,  shall mean, as to any Person,  any other Person which
directly  or  indirectly  controls,  or is  under  common  control  with,  or is
controlled by, such Person. The term "control" (including,  with its correlative
meanings,   "controlled   by"  and  "under  common  control  with")  shall  mean
possession, directly or indirectly, of power to direct or cause the direction of
management or policies  (whether through  ownership of securities or partnership
or other ownership interests, by contract or otherwise).

         IN WITNESS WHEREOF,  CalEnergy,  MidAmerican,  Reincorporation  Sub and
Merger Sub have caused this  Agreement as of the date first  written above to be
signed by their respective officers thereunto duly authorized.

Commenting on the transaction,  David Sokol said: "In merging our companies,  we
are  combining  two leaders in  complementary  markets to create a balanced  and
powerful company.  MidAmerican brings a management team with U.S. utility market
knowledge  and  expertise  in  coal-fired  generation,  call center  operations,
customer service and distribution  processes, as well as a portfolio of low-cost
and efficient operating assets. When combined with CalEnergy's  successful track
record  in  operating  a  regional  gas  and  electric  utility  in  the  U.K.'s
deregulated environment,  and its history of aggressive growth in energy markets
throughout  the  world,   we  have  created  a  formidable   competitor  in  the
deregulating energy markets of the U.S. and beyond.

"I am delighted  that we have  reached an  agreement  with a company that is not
only our neighbor  geographically,  but also shares similar beliefs in the value
of  excellent  and   innovative   service  for  our  customers  and  manages  an
extraordinary team of employees.  I am also personally very excited about having
the talented and dedicated group of employees at MidAmerican join our team."

Stan Bright said:  "This  partnership  preserves the character of MidAmerican to
the  benefit  of our  employees,  our  customers  and  our  communities.  We are
combining two excellent  management  teams and expect no  significant  personnel
changes because there are few duplicative  positions between our companies,  and
we are not merging  utility  operations.  Our personnel and  facilities in Sioux
City,  Davenport  and Des Moines  will  remain  integral  to our  success in the
future."

Bright added: "This adds the scale and expertise that will make us significantly
stronger and even more capable of delivering on our promises to our customers to
provide them with  excellent  service at the best possible  value.  Through this
transaction we will move closer to our goal of regional leadership, while we are
part of a fast-growing energy enterprise.  It is a great deal for our customers,
our employees and for our Midwest region."

The  merger  agreement  is  subject  to  approval  by the  shareholders  of both
companies and the following regulatory  agencies:  the Federal Energy Regulatory
Commission,  the Nuclear  Regulatory  Commission and the Iowa Utilities Board. A
filing will also be made with the Federal  Trade  Commission  and  Department of
Justice under the Hart-Scott Rodino Antitrust  Improvements  Act.  Completion of
the merger is expected to occur in the first quarter of 1999.

CalEnergy  was advised by Credit Suisse First Boston Corp.  and Lehman  Brothers
Inc., and MidAmerican was advised by Warburg Dillon Read LLC.

into Illinois and other markets. David Sokol stated: "This provides an excellent
concrete  example of the benefits of bringing these two companies  together.  We
can  immediately  combine  MidAmerican's  local  permitting and regional  energy
trading  expertise with  CalEnergy's  generation  development  and  construction
expertise,  to pursue opportunities from existing available sites as the Midwest
power market deregulates."
