ITEM 5.  OTHER EVENTS.

         On October 25,  1999,  the  Registrants  indirect  parent,  MidAmerican
Energy Holdings  Company (the  "Parent"),  announced that it had entered into an
Agreement  and Plan of  Merger,  dated  as of  October  24,  1999  (the  "Merger
Agreement"),  with  entities  formed by an investor  group  including  Berkshire
Hathaway  Inc.,  Mr. Walter Scott,  Jr. and Mr. David L. Sokol.  Pursuant to the
Merger Agreement,  the investor group's acquisition  vehicle,  Teton Acquisition
Corp., will be merged with and into the Parent, with the Parent as the surviving
corporation  in the merger,  and holders of the Parent's  common stock will have
the right to receive $35.05 per share in cash, without interest.

SHAREHOLDER AND OTHER APPROVALS

         Consummation of the  transactions  contemplated by the Merger Agreement
is subject to the  approval  of the  holders  of a majority  of the  outstanding
shares of the Parent's  common stock and other customary  conditions,  including
the regulatory  requirements described below, all of which have been obtained or
are presently  expected to be obtained by the  Registrant by no later than March
31,  2000.  The special  meeting of  Shareholders  of the Parent to consider the
merger proposal is scheduled for January 27, 2000.

         HART-SCOTT-RODINO

                  The  Hart-Scott-Rodino  Act provides that transactions such as
         the merger may not be  completed  until  certain  information  has been
         submitted to the  Antitrust  Division of the  Department of Justice and
         the Federal Trade Commission and specified waiting period  requirements
         have been satisfied.  Notice of early termination of the waiting period
         was granted by the FTC on November 29, 1999.

         FEDERAL POWER ACT

                  Section 203 of the Federal  Power Act provides  that no public
         utility  shall  sell  or  otherwise   dispose  of  its   jurisdictional
         facilities  or  directly  or  indirectly   merge  or  consolidate  such
         facilities  with those of any other  person or acquire any  security of
         any other public utility without first obtaining authorization from the
         FERC. On December 15, 1999,  the  Registrant  received FERC approval of
         the merger under Section 203 of the Federal Power Act.

         IOWA PUBLIC UTILITY REGULATION

                  Iowa law provides that a merger or  consolidation of the whole
         or any substantial part of a public utility's assets shall not take

<PAGE>

         place if the Iowa Utilities Board (the "IUB") disapproves.  On November
         12,  1999,  the  Registrant,  the  Parent,  Teton  Formation  and Teton
         Acquisition  Corp.  filed an  application  with  the IUB for its  order
         permitting the merger to occur.  Iowa law provides that the application
         will be deemed approved unless the IUB disapproves the merger within 90
         days after the filing of the  application,  unless  such time period is
         extended by the IUB, for good cause shown, for an additional period not
         to  exceed  90 days.  Iowa law  further  provides  that the IUB  cannot
         disapprove  the merger without  providing for a notice and  opportunity
         for hearing.  On December 16, 1999,  the IUB issued a procedural  order
         extending the initial  90-day  period for an  additional  90 days.  The
         hearing is presently  scheduled for February 16, 2000,  and the IUB has
         indicated  in its order  that it  presently  intends to issue its final
         order by no later than March 31, 2000.

         ILLINOIS PUBLIC UTILITY REGULATION

                  Under  Illinois  law,  the  Registrant  will seek  (subject to
         certain  reservations of rights) the approval of the Illinois  Commerce
         Commission  ("ICC") for the gas utility  portion of the merger and file
         certain  information  regarding  the  electric  utility  portion of the
         merger with the ICC. The Registrant  believes that the merger qualifies
         for  expedited  treatment  under the ICC approval  and hearing  process
         which,  under statute,  could  otherwise take 11 months.  In two recent
         merger proceedings, including the merger of CalEnergy with MidAmerican,
         expedited  treatment was granted and approval was obtained within three
         months.  On November  15,  1999,  the  Registrant  and Parent  filed an
         application with the ICC and a hearing was held on December 22, 1999.

         PUBLIC UTILITY HOLDING COMPANY ACT OF 1935

                  The  transaction  is not  subject to approval by the SEC under
         the Public Utility Holding Company Act of 1935. Following the effective
         time of the merger,  the  Registrant  and the Parent  will  continue to
         claim an exemption  from  registration  under Section  (3)(a)(1) of the
         1935  Act  pursuant  to  Rule 2  because  after  the  merger  both  the
         Registrant  and Parent  will be  organized  in, and conduct the utility
         operations   substantially   in,   the   State  of  Iowa  and  will  be
         predominantly  intrastate  in  character  in the same  manner  as it is
         today.  The  completion of the merger is  conditioned on the receipt by
         the members of the investor group of evidence  reasonably  satisfactory
         to them that neither they nor any of their  affiliates  will be subject
         to regulation as a registered  public utility holding company under the
         1935 Act.

         NUCLEAR REGULATORY COMMISSION REGULATION

                  The  Registrant  is a  non-operating  25% owner of Quad Cities
         Nuclear  Generating  Station  Units  1 and 2,  which  are  referred  to
         collectively as "Quad Cities". The remaining interests in the two units
         are owned and operated by Commonwealth  Edison Company. On November 16,
         1999, the Registrant (through Commonwealth Edison) submitted an

<PAGE>

         application  to the NRC  pursuant  to 10 C.F.R.  50.80 for  formal  NRC
         consent of the indirect transfer of control.

         EUROPEAN/U.K. COMPETITION FILINGS

                  Under  Regulation  (EEC) No.  4064/89  of the  Council  of the
         European   Union,   as  amended   (the  "EC  Merger   Regulation"),   a
         concentration  (as  defined  in the EC Merger  Regulation)  which has a
         Community  dimension may not be completed until the European Commission
         has granted its approval or such  approval has been deemed to have been
         granted.  On  November 9, 1999,  the Merger Task Force of the  European
         Commission  expressed  its view that the  merger is not  subject to the
         prior approval requirements of the EC Merger Regulation.

                   Certain  notifications and undertakings may be required to be
         made to the UK electricity and gas regulator (OFGEM) in connection with
         the transaction and notifications are currently in the process of being
         submitted.  The merger may be subject to review  under the U.K.  merger
         control rules pursuant to the Fair Trading Act of 1973. Based on advice
         of U.K.  counsel,  the Registrant  believes that a referral to the U.K.
         Competition Commission for detailed review would be unlikely.

         OTHER REGULATORY MATTERS

                  The   Registrant   has  obtained   from   various   regulatory
         authorities  franchises,  permits  and  licenses  which  may need to be
         renewed,  replaced or transferred as a result of the merger. Approvals,
         consents  or  notifications  may be required  in  connection  with such
         renewals, replacements or transfers.

                  Regulatory commissions of states where the Registrant operates
         may intervene in the federal regulatory proceedings. In addition, these
         regulatory  commissions regulate the rates charged to utility customers
         within their  jurisdictions.  In approving  rates,  each state may take
         into account savings, if any, resulting from, and other effects of, the
         merger.

                  The  Registrant is not aware of any material  governmental  or
         regulatory  approvals or actions that may be required for completion of
         the merger other than as described above. If any other  governmental or
         regulatory  approval or action is or becomes  required,  the Registrant
         currently believes that the Parent would seek that additional  approval
         or action.

         Certain information  included in this release contains  forward-looking
statements made pursuant to the Private Securities Litigation Reform Act of 1995
("Reform Act"). Such statements are based on current  expectations and involve a
number of known and unknown risks and uncertainties that could cause the actual

<PAGE>

results and  performance of the Company to differ  materially  from any expected
future  results or  performance,  expressed or implied,  by the  forward-looking
statements. In connection with the safe harbor provisions of the Reform Act, the
Company has  identified  important  factors that could cause  actual  results to
differ materially from such  expectations,  including  development  uncertainty,
operating uncertainty, acquisition uncertainty,  uncertainties relating to doing
business  outside of the Unites  States,  uncertainties  relating to  geothermal
resources,   uncertainties  relating  to  domestic  and  international  (and  in
particular  Indonesian)  economic and  political  conditions  and  uncertainties
regarding  the impact of  regulations,  changes in government  policy,  industry
deregulation  and  competition.  Reference is made to all of the  Company's  SEC
filings,  including  the  Company's  Report  on Form 8-K dated  March 26,  1999,
incorporated herein by reference, for a description of such factors. The Company
assumes  no  responsibility  to  update  forward-looking  information  contained
herein.

                                   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 Parent, the Company,  Merger
Sub or the holder of any of the following securities:

<PAGE>

         (a) Each share  (collectively,  the "Shares") of common  stock,  no par
value, of the Company  ("Company  Common  Stock"),  together with the associated
purchase  rights  ("Company  Rights")  under the Company  Rights  Agreement  (as
defined  in  Section  4.18),  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 $35.05 (the "Per Share
Amount"),  in  cash  payable  to the  holder  thereof,  without  interest,  upon
surrender of the certificate  representing such Share in accordance with Section
2.3.  Throughout  this  Agreement,  the term  "Shares"  refers to the  shares of
Company Common Stock together with the associated Company Rights.

         (b) Each Share held in the treasury of the Company and each Share owned
by Parent,  Merger  Sub or any  direct or  indirect  Subsidiary  (as  defined in
Section  4.1) of Parent,  Merger Sub or the  Company  (other than Shares held in
trust  accounts,  managed  accounts,  custodial  accounts  and the like that are
beneficially  owned by third  parties)  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.  Each share of Zero  Coupon  Convertible
Preferred  Stock of Merger Sub issued and outstanding  immediately  prior to the
Effective Time shall  thereafter  represent one validly  issued,  fully paid and
nonassessable share of Zero Coupon Convertible  Preferred Stock 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
2.2, 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 in accordance with Section 2.3.

         (c) The  Company  shall give  Parent (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 the  Company  and  (ii)  the  opportunity  to  direct  all  negotiations  and
proceedings  with  respect  to demands  for  appraisal  under the Iowa Act.  The
Company shall not voluntarily make any payment with respect to any demands for

<PAGE>

appraisal and shall not, except with the prior written consent of Parent, settle
or offer to settle any such demands.

         Section 2.3. Surrender of Shares; Stock Transfer Books.

         (a) Prior to the Effective  Time, the Company 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 or Merger  Sub  shall  deposit,  or cause to be
deposited (including from available cash balances at the Company), 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 one year after the Effective  Time.  Parent
and Merger Sub agree that as promptly as  practicable  after the Effective  Time
the Surviving  Corporation  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,  the
Surviving  Corporation  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. 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.

         (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 the
Surviving  Corporation  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 the Company
shall be closed and there shall not be any further  registration  of transfer of
any shares of capital stock  thereafter on the records of the Company.  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) and Sections 2.3(b) and (c). 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 one year after the Effective
Time,  the Exchange  Agent shall deliver to the Surviving  Corporation  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  only to the  Surviving  Corporation  (subject  to
applicable  abandoned  property,  escheat and similar  laws) and 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. Options Under Company Stock Plans.

         (a) Except as provided in Section  2.4(b),  the Company  shall take all
actions necessary to provide that,  immediately prior to the Effective Time, (x)
each outstanding  option to acquire shares of Company Common Stock (the "Company
Options")  granted  under any of the Company  Stock Plans (as defined in Section
4.3), whether or not then exercisable or vested,  shall become fully exercisable
and vested,  (y) each Company Option which is then outstanding shall be canceled
and (z) in  consideration  of such  cancellation,  and except to the extent that
Parent and the holder of any such Company Option otherwise agree in writing, the
Company (or, at Parent's option, Parent or the Surviving  Corporation) shall pay
in cash to such holders of Company Options an amount in respect thereof equal to
the product of (A) the excess, if any, for each Company Option, of the Per Share
Amount over the per share exercise price thereof and (B) the number of shares of
Company  Common Stock  subject  thereto  (such  payment to be net of  applicable
withholding  taxes);  provided that the  foregoing  shall not require any action
which violates the Company Stock Plans.

         (b) Certain  Company  Options held by certain members or former members
of Company  management,  as Parent shall notify the Company in writing  prior to
the Effective Time, shall become fully exercisable and vested  immediately prior
to the Effective Time and shall thereafter remain exercisable in accordance with
their terms and any other terms  which are agreed to in writing  between  Parent
and such holders.

         (c) Except as provided in Section  2.4(b) or as otherwise  agreed to in
writing by the parties to this  Agreement,  the Company shall use all reasonable
efforts to ensure that following the Effective Time no holder of Company Options
or any participant in the Company Stock Plans or any other such plans,  programs
or arrangements shall have any right thereunder to acquire any equity securities
(or any  interests  therein) of the Company,  the Surviving  Corporation  or any
Subsidiary thereof.

                                  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

<PAGE>

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
place as Parent and the Company shall mutually agree (the "Closing Date").

                                   ARTICLE IV.
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company hereby  represents and warrants to Parent and Merger Sub as
follows:

         Section 4.1.  Organization and  Qualification.  The Company and each of
the Company  Subsidiaries  and, to the  knowledge  of the  Company,  each of the
Company Joint Ventures is a corporation or other entity duly organized,  validly
existing  and  in  good  standing  under  the  laws  of  its   jurisdiction   of
incorporation  or  organization,  has all requisite  power and authority and has
been duly  authorized  by all necessary  approvals and orders to own,  lease and
operate  its assets and  properties  and to carry on its  business  as it is now
being  conducted  and is duly  qualified  and in good standing to do business in
each  jurisdiction  in which the  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,
financial  condition,  Company  Prospects  (as defined  below) or the results of
operations  of the Company and the Company  Subsidiaries  taken as a whole or on
the  consummation  of the  transactions  contemplated  by this Agreement (to the
extent such adverse effect does not arise from (i) general  economic  conditions
or (ii) the securities  markets  generally) (any such material adverse effect, a
"Company Material Adverse Effect"). The term "Subsidiary" of a Person shall mean
any  corporation  or other entity  (including  partnerships  and other  business
associations  and joint  ventures) in which such Person  directly or  indirectly
owns at least a majority  of the voting  power  represented  by the  outstanding
capital stock or other voting  securities or interests having voting power under
ordinary  circumstances  to elect a majority of the directors or similar members
of the governing  body, or otherwise to direct the management  and policies,  of
such  corporation  or entity,  and the term  "Company  Subsidiary"  shall mean a
Subsidiary of the Company.  The term "Joint  Venture" of a Person shall mean any
corporation  or  other  entity   (including   partnerships  and  other  business
associations  and joint  ventures) in which such Person  directly or  indirectly
owns an  equity  interest  that is less  than a  majority  of any  class  of the
outstanding  voting  securities or equity of any such entity,  other than equity
interests in entities in which such Person does not control the  operations  and
does not appoint at least 50% of the board of directors (or comparable governing
body),  and the term "Company  Joint  Venture" shall mean a Joint Venture of the
Company.  The term "Company  Prospects"  shall mean the prospects of the Company
and the Company Subsidiaries, taken as a whole, but only as they may be affected
by statutory or regulatory  changes (whether relating to utility,  environmental
or other statutory or regulatory matters) or by expropriation events.

         Section  4.2.  Subsidiaries.  Section  4.2  of the  Company  Disclosure
Schedule  delivered  by the  Company to Parent  prior to the  execution  of this
Agreement  (the  "Company  Disclosure  Schedule")  sets  forth a list of all the
Company Subsidiaries and the Company Joint Ventures,  including the name of each
such entity,  a brief  description  of the  principal  line or lines of business
conducted  by each such  entity and the  interest of the Company and the Company
Subsidiaries   therein.  Each  of  the  Company  and  MidAmerican  Funding,  LLC
("MidAmerican Funding") is a "public utility holding company" (as defined in the
Public Utility Holding Company Act of 1935, as amended (the "1935 Act")) exempt

<PAGE>

from all provisions  (other than Section  9(a)(2)) of the 1935 Act,  pursuant to
Section  3(a)(1)  in  accordance  with Rule 2 of the 1935 Act,  and  MidAmerican
Energy Company ("MidAmerican  Utility") is a "public utility company" within the
meaning of Section  2(a)(5) of the 1935 Act. With the  exception of  MidAmerican
Utility and MidAmerican  Funding, no Company Subsidiary or Company Joint Venture
is a "holding  company"  or a "public  utility  company"  within the  meaning of
Sections  2(a)(7) and 2(a)(5) of the 1935 Act,  respectively,  nor,  except with
respect to their relationship with the Company and MidAmerican  Funding, are any
of such entities an "affiliate" or a "subsidiary  company" of a holding  company
within  the  meaning  of  Sections   2(a)(11)  and  2(a)(8)  of  the  1935  Act,
respectively.  Except  as set forth in  Section  4.2 of the  Company  Disclosure
Schedule,  (i) all of the issued and outstanding shares of capital stock of each

of the Code or other laws, rules and regulations required to provide such income
tax benefits.

         (d) Liabilities. With respect to the Company Benefit Plans individually
and in the  aggregate,  there are no actions,  suits,  claims pending or, to the
knowledge of the Company,  threatened,  and, to the knowledge of the Company, no
event has occurred  that could  reasonably be expected to subject the Company or
any of the Company  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 Pension Benefit Guaranty  Corporation (the "PBGC")),  or

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 could not
reasonably be expected to give rise to a Company Material Adverse Effect.

employees.  Except as set forth in  Section  4.10(h) of the  Company  Disclosure
Schedule,  (i) there is no unfair labor practice,  employment  discrimination or

Material Adverse Effect and (iii) there is no proceeding, claim, suit, action or
governmental  investigation  pending  or,  to  the  knowledge  of  the  Company,

indemnification  from the  Company  pursuant  to their  respective  articles  of

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

binding  legal  commitments  existing on  September  30,  1999 and  specifically
identified in Section 4.10(a) of the Company Disclosure  Schedule and except for
normal  increases  in the  ordinary  course  of  business  consistent  with past

Subsidiaries;  (ii) entered into or amended any employment,  severance, pension,

Joint  Ventures,  (B) to the  knowledge  of the  Company,  against any person or
entity whose  liability  for any  Environmental  Claim the Company or any of the
Company  Subsidiaries  or, to the  knowledge of the Company,  any of the Company
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

Hazardous  Material  that  would be  reasonably  likely to form the basis of any
Environmental  Claim against the Company or any of the Company  Subsidiaries  or
the Company Joint Ventures,  or against any person or entity whose liability for
any  Environmental  Claim the Company or any of the Company  Subsidiaries or the
Company Joint Ventures has or may have retained or assumed either  contractually

in the aggregate, a Company Material Adverse Effect.

         (f) Predecessors. Except as set forth in Section 4.11(f) of the Company
Disclosure  Schedule,  the  Company  has  no  knowledge,  with  respect  to  any
predecessor  of the  Company or any of the Company  Subsidiaries  or the Company

expected to require payments of $20 million or more or which could reasonably be
expected to have a Company Material Adverse Effect.

         (g)  Disclosure.  The  Company has  disclosed  in writing to Parent all
material  facts  which  the  Company  reasonably  believes  form the basis of an

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 the Company or any of the Company Subsidiaries for

the Company Subsidiaries required to approve this Agreement,  the Merger and the
other transactions contemplated hereby.

         Section  4.14.  Insurance.  Except as set forth in Section  4.14 of the
Company Disclosure  Schedule,  the Company and each of the Company  Subsidiaries
is, and has been  continuously  since January 1, 1998,  insured with financially

Stock  (other  than the  Investors)  pursuant to this  Agreement  is fair from a
financial  point  of view to such  holders.  True  and  correct  copies  of such
opinions have been provided by the Company to Parent.

<PAGE>

         Section 4.16.  Brokers.  No broker,  finder or investment banker (other
than Dillon Read and Lehman) is entitled to any brokerage, finder's or other fee
or commission in connection with the Merger based upon  arrangements  made by or

with the Merger based upon  arrangements  made by or on behalf of the Company do
not exceed $11 million in the aggregate.

of the business  combination  provisions  of Section 1110 of the Iowa Act or any
similar  provisions of the Iowa Act, the articles of incorporation or by-laws of
the Company 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 the Company have been obtained.

         Section  4.18.  Company  Rights  Agreement.  Prior  to the date of this
Agreement,  the  Company  has  delivered  to Parent  and its  counsel a true and

Agent, and the Company (the "Company Rights Agreement") in effect as of the date
hereof,  and has authorized all necessary action (and promptly after the date of
this  Agreement  and prior to the Closing  Date,  will have taken all  necessary
action),  including amending the Company Rights Plan, such that the consummation
of the  transactions  contemplated  by this  Agreement  will not  result  in the
separation of the Company Rights from the Shares,  the Company  Rights  becoming
non-redeemable,  the Rights  associated  with Shares  beneficially  owned by the
Investors (or their affiliates or associates) becoming void or voidable,  or the
triggering of any right or entitlement of  shareholders of the Company under the
Company Rights Agreement or any similar agreement to which the Company or any of
its affiliates is a party.

         Section  4.19.  Year  2000  Compliance.  The  Company  and the  Company
Subsidiaries  have  put into  effect  reasonable  and  customary  practices  and
programs to be Year 2000  Compliant (as defined  below))  designed to enable all
material software,  hardware and equipment (including  microprocessors) that are
owned or  utilized  by the  Company or any of the  Company  Subsidiaries  in the
operations of its or their  respective  business to be capable,  by December 31,
1999,  of accounting  for all  calculations  using a century and date  sensitive
algorithm  for the year  2000 and the fact that the year 2000 is a leap year and
to otherwise  continue to function without any material  interruption  caused by
the  occurrence of the year 2000 (such  capabilities  are herein  referred to as
being "Year 2000 Compliant").

         Section  4.20.  Board  Recommendation.  The Board of  Directors  of the
Company,  at a meeting  duly  called and held,  has by  unanimous  vote of those
directors  present (who  constituted  all of the directors  then in office other
than David L. Sokol,  Walter  Scott,  Jr. and Bernard W.  Reznicek,  who did not
participate  in such  deliberations  or vote  due to  their  status  as,  and/or
affiliation with, one of the Investors) (i) determined that this Agreement,  the
Merger and the other transaction contemplated hereby are fair to and in the best
interests of the  shareholders  of the Company,  and (ii)  resolved to recommend
that the holders of Company Common Stock approve this Agreement,  the Merger and
the other transactions contemplated hereby.

of the Company  Subsidiaries  to,  except as required  or  contemplated  by this
Agreement,  engage  in any  activities  (i)  which  would  cause a change in its
status, or that of the Company  Subsidiaries,  under the 1935 Act, including any
action or inaction that would cause the prior approval of the SEC under the 1935
Act to be required for the consummation of the Merger and the other transactions
contemplated  hereby,  or (ii) that  would  impair the  ability of the  Company,
MidAmerican  Funding,  Parent or the Surviving  Corporation or any Subsidiary of
Surviving Corporation to claim an exemption as of right under Rule 2 of the 1935
Act  following  the Merger or (iii) that would  subject  Parent or any affiliate

Investor  Entities (as defined in Section  6.2(b)) to regulation as a registered
holding company under such Act following the Merger.

         (g)  Tax-Exempt  Status.  The Company  shall not, nor shall the Company
permit any Company  Subsidiary to, take any action that would likely  jeopardize

this  Agreement and prior to the Effective  Time or earlier  termination of this
Agreement,  except as expressly contemplated or permitted in this Agreement,  or
to the extent the Company  shall have  otherwise  consented  in  writing,  which
decision  regarding consent shall be made as soon as reasonably  practicable (it
being understood that if a particular activity is permissible as a result of its
being disclosed and, where applicable,  approved in writing by the Company under
any one of the Section 6.2 subsections of the Parent Disclosure  Schedule,  that
activity will not be prohibited under any of the subsections of Section 6.2):

inaction that would cause the prior approval of the SEC under the 1935 Act to be
required  for  the  consummation  of  the  Merger  and  the  other  transactions
contemplated  hereby,  (ii)  that  would  impair  the  ability  of the  Company,
MidAmerican  Funding,  Parent or Merger  Sub to claim an  exemption  as of right
under Rule 2 of the 1935 Act  following  the Merger or (iii) that would  subject
Parent or any affiliate (within the meaning of Section 2(a)(11) of the 1935 Act)
of Parent to regulation as a registered holding company under such Act following
the Merger; provided that,  notwithstanding anything contained in this Agreement
to the contrary, in no event shall Parent or Merger Sub or any affiliate (within
the meaning of Section 2(a)(11) of the 1935 Act) of either such entity or any of
Berkshire  Hathaway Inc.,  any subsidiary of Berkshire  Hathaway Inc., any Scott
Family Entity or any entity controlled by either David L. Sokol or Walter Scott,
Jr. (all such persons and entities,  collectively,  the "Investor  Entities") be
required to  restructure  their  capitalization  or amend any of their  existing
shareholder arrangements in order to permit Parent and Merger Sub to qualify for
an exemption from the  requirement  to register as a holding  company under such
Act following  the Merger or in order to ensure that none of Parent,  Merger Sub
or Parent's  affiliates (within the meaning of Section 2(a)(11) of the 1935 Act)

and  frequent  basis  with one or more  representatives  of the  other  party to

to result in a material  breach of any provision of this  Agreement or in any of
its  representations  and warranties set forth in this Agreement being untrue on
and as of the Closing Date.

                                  ARTICLE VII.

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, in whole or in part, (i) are based on or arising out of
the fact that such  person is or was a director or officer of such party or (ii)
arise out of or pertain 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)
the Surviving  Corporation shall pay the reasonable fees and expenses of counsel
for the Indemnified Parties selected by the Indemnified  Parties,  which counsel
may also  serve as  counsel  to the  Surviving  Corporation  (unless  there is a
conflict between the positions of the Surviving  Corporation and the Indemnified
Parties  on any  significant  issue)  and  which  counsel  shall  be  reasonably
satisfactory  to  the  Surviving   Corporation   (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) the Surviving Corporation will cooperate in the

Company  shall  be  made  by  independent  counsel  mutually  acceptable  to the
Surviving  Corporation and the Indemnified  Party (the  "Independent  Counsel");
provided,  however,  that the Surviving  Corporation 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

provided,  that the Surviving Corporation 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 the  Surviving
Corporation 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  Company  Disclosure  Schedule;  provided,
further,  that if such  insurance  cannot be so  maintained  or obtained at such
cost,  the  Surviving  Corporation  shall  maintain  or  obtain  as much of such
insurance for the Company as can be so maintained or obtained at a cost equal to
200 percent of the current annual premiums of the Company for its directors' and
officers' liability insurance.

         (c)  Successors.  In the event the Surviving  Corporation or any of its

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 the
Surviving  Corporation  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

Parent,  the Company and its  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 of this Agreement, shall survive
the Merger and shall  continue in full force and effect for a period of not less
than six years from the Effective Time.

         Section 7.6.  Disclosure  Schedules.  On or before the date hereof, (i)

has  delivered  to Parent the  Company  Disclosure  Schedule,  accompanied  by a
certificate  signed by the chief  financial  officer of the Company  stating the
Company Disclosure Schedule has been delivered pursuant to this Section 7.6. The

referred to herein as the "Disclosure Schedules." The Disclosure Schedules shall
be deemed to  constitute  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

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 affecting
the  representations  and  warranties  contained  herein  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  pertaining  to the  parties'
representations  and  warranties  contained  herein.  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 8.3(b).

<PAGE>

         Section 7.7. Public  Announcements.  Subject to each party's disclosure
obligations imposed by law or regulation,  Parent and the Company 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,  the
Company  will not, and will not  authorize or permit any of its  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 Parent,
any of its 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 the Company or its Board of
Directors  from (i) taking and  disclosing to its  shareholders  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  shareholders  as,  in good  faith  judgment  of its Board of
Directors, after consultation with 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
the Company or any investment  banker,  attorney or other  Representative of the
Company,  whether  or not such  person  is  purporting  to act on  behalf of the
Company or otherwise,  shall be deemed to be a breach of this Section 7.8 by the
Company.  Notwithstanding any other provision hereof, the Company may (i) at any
time  prior  to the time its  shareholders  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 (except
as permitted by Section 7.8), directly or indirectly,  by or with the Company or
its Representatives after the date hereof) seeks to initiate such discussions or
negotiations and may furnish such third party information concerning the Company
and its business,  properties and assets if, and only if, (A)(w) the third party
has first made an  Acquisition  Proposal that is reasonably  expected to be more
favorable to the Company's shareholders than the Merger, taking into account all
legal,  regulatory,  timing  and  financial  aspects  of the  Merger  and of the
Acquisition  Proposal,  including the degree of certainty of financing therefor,
(x) the  Acquisition  Proposal  is  reasonably  capable of being  completed  (as
determined in good faith by the Company's Board of Directors after  consultation
with its  financial  advisors  and  outside  counsel),  (y) the third  party has
demonstrated that financing for the Acquisition Proposal is reasonably likely to
be obtained (as  determined  in good faith by the  Company'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 after  consultation with 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  shareholders  under applicable law and (B) prior to
furnishing such information to or entering into discussions or negotiations with
such person or entity,  the Company (x) provides  prompt notice to Parent to the
effect that it is furnishing information to or entering into discussions or

<PAGE>

negotiations  with such  person or entity and (y)  receives  from such person an
executed confidentiality  agreement substantially similar to the Confidentiality
Agreement,  together  with its written  acknowledgment  and  agreement to pay at
closing  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.  The  Company  shall   immediately   cease  and  terminate  any  existing
solicitation,  initiation,  encouragement,  activity,  discussion or negotiation
with any parties conducted heretofore by the Company or its Representatives with
respect to the  foregoing.  The Company shall notify Parent hereto orally and in
writing  of  any  such  inquiries,  offers  or  proposals  (including,   without
limitation,  the  material  terms and  conditions  of any such  proposal and the
identity of the person making it), within 24 hours of the receipt thereof, shall
keep Parent  informed of the status and  details of any such  inquiry,  offer or
proposal,  and shall give Parent  three  business  days'  advance  notice of any
agreement  (specifying the material terms and conditions  thereof) 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 written proposal or offer
(other  than by Parent or Merger Sub) for a tender or  exchange  offer,  merger,
consolidation  or  other  business  combination  involving  the  Company  or any
material  Company  Subsidiary  or  any  proposal  to  acquire  in any  manner  a
substantial  equity  interest in or a  substantial  portion of the assets of the
Company  or  any  material  Company  Subsidiary,  other  than  the  transactions
contemplated  by this Agreement.  As used in this Section,  "Board of Directors"
includes any committee thereof.

         Section 7.9.  Expenses.  Subject to Section 9.3, all costs and expenses
incurred in connection  with this  Agreement and the  transactions  contemplated
hereby shall be paid by the party incurring such expenses.

         Section 7.10. Third Party Standstill Agreements. During the period from
the date of this Agreement  through the Effective Time,  neither the Company nor
any of its  Subsidiaries  shall terminate,  amend,  modify or waive any material
provision of any confidentiality or standstill agreement to which it is a party.
During such  period,  the Company and its  Subsidiaries  shall  enforce,  to the
fullest  extent  permitted  under  applicable  law, the  provisions  of any such
agreement,  including,  but not limited to, by obtaining  injunctions to prevent
any  breaches  of such  agreements  and to  enforce  specifically  the terms and
provisions thereof in any court having jurisdiction.

         Section 7.11. Takeover Statutes.  If any "business  combination," "fair
price," "moratorium,"  "control stock acquisition" or other form of antitakeover
statute or regulation shall become  applicable to the Merger or the transactions
contemplated  hereby,  the Company and the members of the Board of  Directors of
the Company shall grant such  approvals and take such actions as are  reasonably
necessary  so that the  Merger or the  transactions  contemplated  hereby may be
consummated  as promptly as  practicable  on the terms  contemplated  hereby and
otherwise act to eliminate or minimize the effects of such statute or regulation
on the Merger or the transactions contemplated hereby.

         Section 7.12. Subscription Agreements. Parent and Merger Sub agree that
they  will not,  without  the  prior  consent  of the  Company,  enter  into any
amendment to, or modification or waiver of, any of the  Subscription  Agreements
if such amendment, modification or waiver would (i) reduce the aggregate amount

<PAGE>

of funds  committed  under  the  Subscription  Agreements,  (ii) add  additional
conditions  to  the  consummation  of  the  transactions   contemplated  by  the
Subscription  Agreements or (iii) have a material adverse effect on or delay the
receipt of any of the Parent  Statutory  Approvals  or the  consummation  of the
Merger.  Parent and Merger Sub shall  enforce to the  fullest  extent  permitted
under applicable law, the provisions of Subscription  Agreements,  including but
not  limited to  obtaining  injunctions  to enforce  specifically  the terms and
provisions thereof in any court having jurisdiction. Parent and Merger Sub shall
use all  reasonable  efforts  to  fulfill  all of their  obligations  under  the
Subscription  Agreements  and to cause  all  conditions  to  funding  under  the
Subscription Agreements (other than conditions to funding that are conditions to
consummation  of the Merger under this Agreement) to be fulfilled as promptly as
reasonably  practicable.  Parent and Merger  Sub shall give the  Company  prompt
written notice of (i) any material  breach or threatened  material breach by any
party of the  terms  or  provisions  of the  Subscription  Agreements,  (ii) any
termination or threatened  termination of any of the Subscription  Agreements or
(iii) any  exercise or  threatened  exercise of any  condition  under any of the
Subscription Agreements.

         Section  7.13.  Employee  Benefits  Matters.  (a)  Except to the extent
necessary to avoid duplication of benefits, the Surviving Corporation shall give
Company  Employees full credit for purposes of eligibility and vesting under any
employee benefit plans or arrangements  maintained by the Surviving  Corporation
or any of its  Subsidiaries  in which such employees are eligible to participate
for such  employees'  service with the Company and its  Subsidiaries to the same
extent  recognized by the Company and its Subsidiaries  immediately prior to the
Effective Time. The Surviving  Corporation shall (i) waive all limitations as to
preexisting   conditions   exclusions  and  waiting   periods  with  respect  to
participation  and coverage  requirements  applicable to Company Employees under
any welfare plan that such employees may be eligible to participate in after the
Effective  Time,  other than  limitations or waiting periods that are already in
effect with respect to such employees and that have not been satisfied as of the
Effective  Time under any welfare  plan  maintained  for the  Company  Employees
immediately  prior to the Effective Time, and (ii) provide each Company Employee
with credit for any co-payments and deductibles paid prior to the Effective Time
in satisfying any applicable deductible or out-of-pocket  requirements under any
welfare  plans that such  employees  are  eligible to  participate  in after the
Effective Time.

         (b) The  Surviving  Corporation  shall  comply  with  the  terms of all
Company Benefit Plans.

         (c) The Company shall take all such steps as may be reasonably required

dispositions of the Company equity securities (including derivative  securities)
in  connection  with this  Agreement  by each  individual  who is a director  or
officer of the  Company to be exempt  under  Rule  16b-3  promulgated  under the
Exchange  Act, such steps to be taken in  accordance  with the No-Action  Letter
dated January 12, 1999,  issued by the SEC to Skadden,  Arps,  Slate,  Meagher &

cash to the Exchange Agent  required  pursuant to Section  2.3(a),  assuming all
other  conditions to Closing have been satisfied or otherwise  waived in writing
by Parent), and, in case of each of clauses (A) and (B) above, such breach shall
not have been  remedied  within twenty days after receipt by Parent of notice in
writing from the Company,  specifying  the nature of such breach and  requesting
that it be remedied and  provided,  that,  any  materiality  standard  expressly
included in such representations,  warranties,  covenants or agreements shall be
ignored for purposes of this Section 9.1(g);

         (h) by the  Company if any of the  Subscription  Agreements  shall have
been  terminated at any time when Parent would not be entitled to terminate this
Agreement  pursuant  to Section  9.1(b),  (c),  (d) or (f) and,  within ten (10)
business days after any such termination,  such Subscription Agreement shall not
have been replaced  with another  Subscription  Agreement  with such Investor or

Berkshire Hathaway Inc. for financial  accounting  purposes) at least 70% of the
equity   (determined  by  reference  to  economic  interest)  in  the  Surviving

         Section 9.2. Effect of Termination. In the event of termination of this

9.3 and except that the agreement  contained in the last sentence of Section 7.1
shall survive the termination.

         Section 9.3. Termination Fee; Expenses.

         (a)  Termination  and Expense Fees. If this Agreement (i) is terminated
by Parent pursuant to Section  9.1(f)(ii),  or (ii) is terminated by the Company
pursuant to Section  9.1(e),  then the Company shall pay to Parent promptly (but
not later than five  business days after such notice is given or received by the
Company pursuant to Section 9.1(f)(ii) or 9.1(e)) a termination fee equal to $40
million in cash plus an  additional  $8 million in cash (the  "Expense  Amount")
constituting  reimbursement  of expenses and fees  incurred or to be incurred by
Parent or  Merger  Sub in  connection  with or  related  to the  Merger  and the
transactions contemplated by this Agreement, without any requirement that Parent
or Merger Sub account for actual  expenses.  If (i) this Agreement is terminated
pursuant to Section  9.1(b),  9.1(c) or  9.1(f)(i)  and (ii) at the time of such
termination, there shall have been an Acquisition Proposal made by a third party
which, at the time of such termination,  shall not have been (x) rejected by the
Company  and its Board of  Directors  and (y)  withdrawn  by the third party and
(iii)  within  eighteen  months  of any such  termination,  the  Company  or its
affiliate  becomes a subsidiary  or part of such third party or a subsidiary  or
part of an affiliate of such third party, or merges with or into the third party

<PAGE>

or a  subsidiary  or  affiliate  of the third party or enters into a  definitive
agreement  to  consummate  an  Acquisition  Proposal  with such  third  party or
affiliate  thereof,  then the Company shall pay to Parent, at the closing of the
transaction  (and as a  condition  to the  closing)  in which the Company or its
affiliate  becomes such a subsidiary or part of such other person or the closing
of such  Acquisition  Proposal occurs, a termination fee equal to $40 million in
cash plus (unless the Expense Amount is paid pursuant to the following sentence)
the Expense  Amount.  If this  Agreement is  terminated  pursuant to (i) Section
9.1(b) due to any failure to satisfy any of the conditions set forth in Sections
8.1(b),  8.1(c) or 8.3 (other than  8.3(g)),  or (ii) Section  9.1(d) or Section
9.1(f)(i),  the Company  shall pay to Parent  promptly  (but not later than five
business  days after such  notice of  termination  is given or  received  by the
Company) the Expense Amount.

         (b) If this  Agreement is terminated by the Company,  by written notice
to Parent,  due to the failure of Parent and Merger Sub to deposit,  or cause to
be deposited  (including from available cash balances at the Company),  the cash
to the Exchange  Agent  required  pursuant to Section  2.3(a) at a time when all
conditions  to Parent's  obligation  to close have been  satisfied  or otherwise
waived in writing by Parent,  then Parent shall pay to the Company a termination
fee of $40  million,  plus  additional  damages  (but only if and to the  extent
proven) in an amount not to exceed $40 million.

         (c) 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.

         (d)  Limitation  Of  Fees.   Notwithstanding  anything  herein  to  the
contrary,  if any Investor (x) would,  upon  consummation of the Merger,  become
subject to regulation as a public utility holding  company  required to register
under  the 1935  Act and (y)  solely  as a result  thereof,  this  Agreement  is
terminated, then no fees under this Section 9.3 shall be payable by the Company.

         Section 9.4. Amendment. This Agreement may be amended by Parent and the
Boards of  Directors  of the Company and Merger Sub, at any time before or after
the Company Shareholders'  Approval has been obtained and prior to the Effective
Time,  but after such Approval has been obtained,  no such  amendment  shall (a)
alter or change the Per Share Amount 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
Company Common Stock.  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

shall be valid if set forth in an instrument in writing signed on behalf of such
party.
