                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

Item 1.   Description of Registrant's Securities to be
          Registered.

     On December 18, 1996,  the Board of Directors  (the "Board") of MidAmerican
Energy  Holdings  Company,  and Iowa  corporation  (the  "Company"),  declared a
dividend of one preferred stock purchase right (a "Right") for each  outstanding
share of Common Stock, no par value (the "Common  Stock"),  of the Company.  The
dividend is payable on December 30, 1996 (the  "Record  Date") to the holders of
record of the Common  Stock at the Close of  Business  on such date.  Each Right
entitles the holder  thereof  (except as described  below) to purchase  from the
Company  one  one-hundredth  of a share of the  Series  A  Junior  Participating
Preferred  Stock  (the  "Preferred  Shares"),  of the  Company  at a price  (the
"Exercise Price") of $50.00 per one one-hundredth of a Preferred Share,  subject
to adjustment.  The terms of the Rights are set forth in the Stockholders Rights
Agreement  dated as of December  18, 1996 (the "Rights  Agreement")  between the
Company and  Continental  Stock Transfer & Trust  Company,  as Rights Agent (the
"Rights  Agent").  Capitalized  terms not  defined  herein  have the  respective
meanings specified in the Rights Agreement.

                     Distribution Date; Transfer of Rights.

     Initially,  the Rights  associated with the Common Stock  outstanding as of
the Record  Date will be  evidenced  solely by the stock  certificates  for such
Common Stock, with a copy of the Summary of Rights comprised of Exhibit C to the
Rights  Agreement (the "Summary of Rights")  attached  thereto.  The Rights will
separate  from the Common  Stock upon the  earliest  to occur of (i) 10 Business
Days after the first public  announcement  that any Person (other than an Exempt
Person (as hereinafter  defined)) has become an Acquiring Person (as hereinafter
defined), (ii) 10 Business Days (or such other Business Day as may be determined
by  action  of the  Board  prior to the time  that any  Person  shall  become an
Acquiring  Person or declared to be an Adverse Person (as  hereinafter  defined)
after the  commencement  by any Person (other than an Exempt  Person) of, or the
first public  announcement  of its  intention to commence,  a tender or exchange
offer if, upon the  consummation  thereof,  such Person would be the  Beneficial
Owner of 15% or more of the  outstanding  shares  of  Common  Stock and (iii) 10
Business Days after a determination by at least a majority of the  Disinterested
Directors (as hereinafter  defined) who are not officers of the Company that any
Person has become an Adverse  Person  (the  earliest of the dates  specified  in
clauses (i), (ii) and (iii) being hereinafter  called the "Distribution  Date").
After the  Distribution  Date,  the Rights will be evidenced  solely by separate
certificates and will trade independently from the Common Stock.

     An  "Acquiring  Person"  is any  Person  who or  which,  together  with its
Affiliates  and  Associates,  has  acquired  15% or more of the shares of Common
Stock  then  outstanding,  but  does  not  include  (i) the  Company,  (ii)  any
Subsidiary of the Company, (iii) any employee benefit plan or other compensation
program or  arrangement  of the  Company or of any such  Subsidiary  or (iv) any
Person  holding  shares of Common Stock for or pursuant to the terms of any such
plan,  program or arrangement (the Persons specified in clauses (i) through (iv)
being herein collectively  called "Exempt Persons").  An "Adverse Person" is any
Person who or which,  together with its Affiliates and Associates,  has acquired
10% or  more of the  shares  of  Common  Stock  then  outstanding  and has  been
determined,  by at least a majority of the  Disinterested  Directors who are not
officers of the Company,  to be likely to act in a manner  designed to produce a
short-term financial gain for such Person to the detriment of the best long-term
interests of the Company and its stockholders. A "Disinterested Director" is (i)
any member of the Board who is not a Restricted Person (as hereinafter defined),
or a representative or nominee of a Restricted  Person,  and was a member of the
Board  prior to the date of the Rights  Agreement  and (ii) any  individual  who
subsequently  becomes a member of the Board and is not a Restricted Person, or a
representative  or nominee of a  Restricted  Person,  and whose  nomination  for
election  to  the  Board  is  recommended  or  approved  by a  majority  of  the
Disinterested  Directors then in office.  A "Restricted  Person" is an Acquiring
Person, an Adverse Person or any Affiliate or Associate thereof.

     The Rights Agreement  provides that,  until the  Distribution  Date (or the
earlier  redemption or expiration of the Rights),  the Rights may be transferred
only with the associated shares of Common Stock. Until the Distribution Date (or
the earlier  redemption  or expiration of the Rights),  stock  certificates  for
Common Stock issued after the Record Date,  either upon transfer of  outstanding
shares or original issuance of additional shares of Common Stock, will contain a
legend  incorporating the Rights Agreement by reference.  Until the Distribution
Date (or the earlier redemption or expiration of the Rights),  the surrender for
transfer of any stock  certificate  for shares of Common Stock,  with or without
such  legend  and  whether or not a copy of the  Summary  of Rights is  attached
thereto,  will also  constitute the transfer of the Rights  associated  with the
shares of Common Stock represented by such stock certificate.

<PAGE>

     As soon as practicable after the Distribution Date,  separate  certificates
evidencing the Rights ("Rights  Certificates")  will be mailed to the holders of
record of the Common Stock as of the Close of Business on the Distribution Date,
which thereafter will constitute the sole evidence of the Rights.  Each share of
Common  Stock  issued  by the  Company  after the  Record  Date and prior to the
earlier  redemption or expiration of the Rights,  including any shares of Common
Stock issued by reason of the exercise of any option, warrant, right (other than
the Rights) or conversion or exchange  privilege  (however  evidenced) issued by
the Company  prior to the  Distribution  Date,  will be  accompanied  by a Right
(unless the Board expressly  provides to the contrary at the time of issuance of
any  such  option,  warrant,  right  or  privilege),   and  Rights  Certificates
evidencing such Rights will be issued at the same time as the stock certificates
for the associated shares of Common Stock.

     The Rights are not exercisable until the Distribution Date.  Moreover,  the
time when the Rights may be  exercised  is  restricted  as described in the next
paragraph.  The Rights will expire on December  30, 2006 (the "Final  Expiration
Date"),  unless the Final  Expiration  Date is extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case as described below.

                 Exercise of Rights Under Certain Circumstances.

     In the event that any Person becomes an Acquiring  Person or is declared to
be an  Adverse  Person,  proper  provision  will be made so that the  registered
holder of each Right (other than Rights  Beneficially  Owned as described in the
next sentence) will thereafter have the right to receive, upon exercise thereof,
the number of shares of Common Stock  which,  at the time of the  occurrence  of
such  event,  will  have a market  value  equal to two  times  the then  current
Exercise Price.  After the first occurrence of either of the events described in
the preceding  sentence,  all Rights which are, or (under certain  circumstances
specified  in the Rights  Agreement)  were,  Beneficially  Owned by a Restricted
Person or  specified  transferees  therefrom  will be or become  void.  Under no
circumstances may a Right be exercised after the occurrence of either such event
unless  the  Company's  right to redeem  the  Rights  (as  described  below) has
expired.

     If, on or after the date on which any Person has become an Acquiring Person
or been  declared to be an Adverse  Person,  any of the  following  transactions
occur:  (i)  the  Company  merges  into  or  consolidates   with  an  Interested
Shareholder  (as  hereinafter  defined) or,  unless all holders of the Company's
outstanding  shares of Common Stock are treated the same,  another  Person (with
limited designated  exceptions);  (ii) an Interested  Shareholder or, unless all
holders of the  Company's  outstanding  shares of Common  Stock are  treated the
same,  another  Person  (with  limited  designated  exceptions)  merges into the
Company and either (A) all or part of the outstanding  shares of Common Stock of
the Company are converted  into capital  stock or other  securities of any other
Person (or the  Company),  cash and/or other  property or (B) such shares remain
outstanding,  unconverted and unchanged; or (iii) the Company sells or transfers
50% or more  of its  consolidated  assets  or  earning  power  to an  Interested
Shareholder or, unless all holders of the Company's outstanding shares of Common
Stock are treated the same, another Person (with limited designated exceptions);
proper provision will be made so that the registered holder of each Right (other
than  Rights  which  have  become  void)  will  thereafter  have the right  (the
"Flip-Over  Right") to  receive,  upon  exercise  thereof,  the number of common
shares of the acquiror (or of another Person affiliated therewith) which, at the
time of consummation of such transaction,  will have a market value equal to two
times the then  current  Exercise  Price.  An  "Interested  Shareholder"  is any
Restricted  Person or any  Affiliate  or  Associate of any other Person in which
such  Restricted  Person has an  interest,  or any Person  acting,  directly  or
indirectly, on behalf of or in concert with any such Restricted Person.

     Adjustments to Exercise Price and Stock Purchasable Upon Exercise.

     The Exercise Price payable,  the number and kind of shares of capital stock
issuable  upon exercise of the Rights and the number of Rights  outstanding  are
subject to adjustment from time to time to prevent  dilution (i) in the event of
a dividend  payable in Preferred  Shares on, or a  subdivision,  combination  or
reclassification of, the Preferred Shares, (ii) upon the grant to the holders of
the Preferred Shares of certain options,  warrants or rights to subscribe for or
purchase  Preferred  Shares  at a  price,  or  securities  convertible  into  or
exchangeable for Preferred Shares with a conversion or exchange price, less than
the  then  Fair  Market  Value  of  the  Preferred  Shares  or  (iii)  upon  the
distribution  to the  holders  of the  Preferred  Shares  of  cash,  securities,
evidences of indebtedness or other property (other than a regular quarterly cash
dividend or a dividend  payable in  Preferred  Shares) or  options,  warrants or
rights (other than those referred to in clause (ii) above).

     The number of outstanding  Rights and the number of one one-hundredths of a
Preferred  Share  issuable  upon  exercise  of each  Right are also  subject  to
adjustment  in the event of a dividend on the Common Stock  payable in shares of
Common Stock or a  subdivision,  combination or  reclassification  of the Common
Stock occurring, in any such case, prior to the Distribution Date.

<PAGE>

     With certain specified exceptions, no adjustment in the Exercise Price will
be made  until  the  cumulative  adjustments  required  equal at least 1% of the
Exercise Price. The Company is not required to issue fractional Preferred Shares
(other than fractions  which are multiples of one  one-hundredth  of a Preferred
Share), but in lieu thereof the Company would be required to make a cash payment
based on the Fair  Market  Value of the  Preferred  Shares  on the  trading  day
immediately preceding the date of exercise.

     Terms of Preferred Shares.

     The  Preferred  Shares  receivable  upon exercise of the Rights will not be
redeemable.  Each  Preferred  Share will entitle the holder thereof to receive a
preferential  quarterly  dividend equal to the greater of (i) $0.01 and (ii) 100
times the aggregate per share amount of all cash  dividends,  plus 100 times the
aggregate per share amount (payable in kind) of all non-cash dividends and other
distributions  (other  than in shares of Common  Stock),  declared on the Common
Stock during such quarter, adjusted to give effect to any dividend on the Common
Stock  payable  in shares of Common  Stock or any  subdivision,  combination  or
reclassification of the Common Stock (a "Dilution Event").  Each Preferred Share
will entitle the holder thereof to 100 votes on all matters  submitted to a vote
of the  stockholders of the Company,  voting together as a single class with the
holders of the Common Stock and the holders of any other class of capital  stock
having general voting rights,  adjusted to give effect to any Dilution Event. In
the event of liquidation of the Company, the holder of each Preferred Share will
be entitled to receive a preferential  liquidation  payment equal to the greater
of (i) $1.00 and (ii) 100 times the aggregate per share amount to be distributed
to the holders of the Common  Stock,  adjusted  to give  effect to any  Dilution
Event, plus an amount equal to accrued and unpaid dividends and distributions on
such Preferred Share,  whether or not declared,  to the date of such payment. In
the  event of any  merger,  consolidation  or  other  transaction  in which  the
outstanding shares of Common Stock of the Company are exchanged for or converted
into other capital stock, securities, cash and/or other property, each Preferred
Share will be  similarly  exchanged  or  converted  into 100 times the per share
amount  applicable to the Common Stock,  adjusted to give effect to any Dilution
Event.

     Because of the nature of the dividend, voting, liquidation and other rights
accorded  to each  Preferred  Share,  the  value of the one  one-hundredth  of a
Preferred Share  receivable  upon the exercise of each Right should  approximate
the value of one share of Common Stock.

     Redemption of Rights.

     At any time prior to the  earliest of (i) 10 Business  Days after the first
public  announcement that any Person (other than an Exempt Person) has become an
Acquiring Person, (ii) 10 Business Days after any Person has been declared to be
an Adverse  Person,  (iii) the occurrence of any  transaction  which permits the
exercise of the Flip-Over  Right and (iv) the Final  Expiration  Date, the Board
may redeem  the Rights in whole,  but not in part,  at the  redemption  price of
$0.01 per Right,  adjusted to give effect to any Dilution Event (the "Redemption
Price");  provided,  however, that, under certain circumstances specified in the
Rights Agreement,  the Rights may not be redeemed unless there are Disinterested
Directors  in office and such  redemption  is approved by at least a majority of
such Disinterested Directors. The redemption of the Rights may be made effective
at such time, on such basis and with such  conditions as the Board,  in its sole
discretion,  may establish.  Immediately after action by the Board directing the
redemption of the Rights, the option to exercise the Rights will terminate,  and
thereafter each registered holder of the Rights will only be entitled to receive
the Redemption Price therefor.

     Exchange of Rights.

     At any time  after  any  Person  has  become  an  Acquiring  Person or been
declared  to be an Adverse  Person and prior to the time that any Person  (other
than an Exempt Person), together with its Affiliates and Associates,  has become
the Beneficial  Owner of 50% or more of the outstanding  shares of Common Stock,
the Board may direct that all or any part of the outstanding  Rights (other than
Rights which have become  void) be  exchanged  for shares of Common Stock at the
exchange rate of one share of Common Stock (or one  one-hundredth of a Preferred
Share or of another  share of capital  stock of the  Company  having  equivalent
rights,  preferences and  privileges) per Right,  adjusted to give effect to any
Dilution Event.

<PAGE>

     Amendment of the Rights and the Rights Agreement.

     Prior to the  Distribution  Date,  the terms of the  Rights  and the Rights
Agreement may be  supplemented  or amended by the Board in any manner.  From and
after the  Distribution  Date, the Rights may be  supplemented or amended by the
Board,  without the approval of the holders of the Rights,  in certain  respects
which do not adversely  affect, as determined by the Board (with the concurrence
of at least a majority of the  Disinterested  Directors),  the interests of such
holders;  provided,  however,  that the  Rights  Agreement  cannot be amended to
lengthen (i) any time period unless (A) such lengthening is approved by at least
a majority of the  Disinterested  Directors and (B) such  lengthening is for the
benefit of the  holders of the Riqhts or (ii) any time  period  relating to when
the Rights may be redeemed if at such time the Rights are not then redeemable.

     Miscellaneous.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     A copy of the  Rights  Agreement  has  been  filed  as an  Exhibit  to this
Registration  Statement.  A copy of the Rights  Agreement is  available  free of
charge from the Company.  The foregoing  summary  description of the Rights does
not purport to be complete  and is qualified in its entirety by reference to the
Rights Agreement, which is hereby incorporated herein by reference.

                  Shareholders  Rights  Agreement  dated as of December 18, 1996
(this  "Agreement")   between  MidAmerican  Energy  Holdings  Company,  an  Iowa
corporation  (the  "Company"),  and Continental  Stock Transfer & Trust Company,
(the "Rights Agent").

                              W I T N E S S E T H :

                  WHEREAS,  the Board of  Directors  of the  Company  desires to
provide all shareholders of the Company with the opportunity to benefit from the
long-term  prospects  and  value  of the  Company  and to  ensure  that all such
shareholders  receive  fair and equal  treatment  in the  event of any  proposed
takeover of the Company; and

                  WHEREAS,  on December 18, 1996,  the Board of Directors of the
Company authorized and declared a dividend of one preferred stock purchase right
(individually a "Right" and  collectively the "Rights") for each share of Common
Stock  (as  hereinafter  defined)  of the  Company  outstanding  at the Close of
Business on December 30, 1996 (the "Record Date"),  each Right  representing the
right to  purchase  one  one-hundredth  of a  Preferred  Share  (as  hereinafter
defined)  upon the terms and subject to the  conditions  herein after set forth,
and  contemplates  that one Right will be issued  with  respect to each share of
Common Stock which shall become  outstanding  after the Record Date and prior to
the earlier of the Redemption Date and the Final  Expiration Date (as such terms
are hereinafter defined),  including any shares of Common Stock issued by reason
of the  exercise  of any  option,  warrant,  right  (other  than the  Rights) or
conversion or exchange privilege contained in any option,  warrant, right (other
than the Rights) or convertible or  exchangeable  security issued by the Company
prior to the Dis tribution Date, unless the Board (as hereinafter defined) shall
expressly  provide to the  contrary at the time of issuance of any such  option,
warrant, right or convertible or exchangeable secu rity.

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual agreements herein set forth, the parties hereto agree as follows:

                  Section  1.  Certain  Definitions.  For all  purposes  of this
Agreement, unless the context otherwise requires, the following terms shall have
the respective meanings set forth below:

                  (a)  "Acquiring  Person"  shall  mean any Person who or which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial  Owner of 15% or more of the  shares of Common  Stock of the  Company
then outstanding, but shall



                                       -1-

not include (i) the  Company,  (ii) any  Subsidiary  of the  Company,  (iii) any
employee  benefit  plan or other  compensation  program  or  arrangement  of the
Company or of any such  Subsidiary  or (iv) any Person  holding  such  shares of
Common  Stock  for or  pursuant  to the  terms  of any  such  plan,  program  or
arrangement (the Persons specified in clauses (i) through (iv) being hereinafter
collectively  called "Exempt Persons").  Notwithstanding the preceding sentence,
no Person shall become an "Acquiring  Person" as the result of an acquisition by
the  Company of shares of its Common  Stock  which,  by reason of  reducing  the
number of its then outstanding shares of Common Stock,  increases the percentage
of its then outstanding shares of Common Stock Beneficially Owned by such Person
to 15% or  more;  provided,  however,  that if such  Person  shall,  after  such
purchase by the Company, become the Beneficial Owner of any additional shares of
Common  Stock  of the  Company,  then  such  Person  shall  be  deemed  to be an
"Acquiring Person."  Notwithstanding the foregoing, if the Board of Directors of
the Company  determines  in good faith that a Person who would  otherwise  be an
"Acquiring  Person" (as defined  pursuant to the  foregoing  provisions  of this
paragraph  (a)) has  become  such  inadvertently,  and such  Person  divests  as
promptly as  practicable  a sufficient  number of shares of Common Stock so that
such Person would no longer be an "Acquiring Person" (as defined pursuant to the
foregoing  provisions  of this  paragraph  (a)),  then such Person  shall not be
deemed to be an "Acquiring Person" for any purposes of the Agreement.

                  (b)  "Adverse  Person"  shall mean any Person  declared  by at
least a majority of the members of the Board who are not officers of the Company
to be an Adverse  Person upon a  determination  that the  criteria  set forth in
Section 11(a)(ii)(B) apply to such Person.

                  (c)  "Affiliate"  and  "Associate"  shall have the respec tive
meanings  ascribed to such terms in Rule 12b-2, as in effect on the date of this
Agreement,  under the  Exchange  Act;  provided,  however,  that no  director or
officer of the Company  shall be deemed an  Affiliate  or Associate of any other
director  or  officer  of the  Company  solely as a result of his or her being a
director or officer of the Company.

                  (d) "Beneficial Owner" (including the terms "Beneficially Own"
and  "Beneficial  Ownership"),  when used with  respect to any Person,  shall be
deemed to include any securities which:

                  (i)  such  Person  or any of  such  Person's  Affili  ates  or
         Associates  beneficially  owns,  directly or indi rectly (determined as
         provided in Rule 13d-3, as in



                                       -2-

         effect on the date of this Agreement, under the Exchange Act);

                  (ii)  such  Person  or  any of  such  Person's  Affiliates  or
         Associates, directly or indirectly, has:

                           (A) the  right  to  acquire  (whether  such  right is
                  exercisable  immediately  or only after the passage of time or
                  upon the satisfaction of any conditions,  or both) pursuant to
                  any written or oral  agreement,  arrangement or  understanding
                  (other than customary  agreements with and among  underwriters
                  and selling  group  members with respect to a bona fide public
                  offering of  securities),  upon the  exercise of any  options,
                  warrants,  rights  (other  than the Rights) or  conversion  or
                  exchange privileges or otherwise;  provided,  however,  that a
                  Person  shall not be  deemed  the  Beneficial  Owner of, or to
                  Beneficially Own: (I) securities tendered pursuant to a tender

                  of such Person's  Affiliates or Associates until such tendered
                  securities  are  accepted  for  purchase  or  exchange or (II)
                  securities  issuable  upon  exercise of the Rights at any time
                  prior to the Distribution Date; or

                           (B) the right to vote pursuant to any written or oral
                  agreement,  arrangement or understanding;  provided,  however,
                  that a Person shall not be deemed the Beneficial  Owner of, or
                  to Beneficially  Own, any security  otherwise  subject to this
                  item (B) if such agreement,  arrangement or  understanding  to
                  vote (I) arises solely from a revocable proxy or consent given
                  to  such  Person  or  any  of  such  Person's   Affiliates  or
                  Associates   in  response   to  a  public   proxy  or  consent
                  solicitation  made  pursuant to, and in accordance  with,  the
                  applicable  rules and  regulations  under the Exchange Act and

                  under the Exchange Act; or

                           (C) the right to dispose of  pursuant  to any written
                  or oral agreement,  arrangement or  understanding  (other than
                  customary  agreements with and among  underwriters and selling
                  group  members with respect to a bona fide public  offering of
                  securities); or

                  (iii) are beneficially owned,  directly or indirectly,  by any
         other Person with which such Person or any of such Person's  Affiliates
         or Associates has

         hereof  to  certain  Rights  as set  forth in the  Shareholders  Rights
         Agreement  dated as of  December  18,  1996  (the  "Rights  Agreement")
         between   MidAmerican  Energy  Holdings  Company  (the  "Company")  and
         Continental Stock Transfer & Trust Company, as Rights Agent, the terms,
         provisions and conditions of which are incorporated herein by reference
         and  made a  part  hereof.  The  Rights  Agreement  is on  file  at the
         principal office of the Company and the principal office of such Rights
         Agent,  and the Company will mail to the holder of this  certificate  a
         copy  thereof  without  charge  after  receipt  of  a  written  request
         therefor.  Under  certain  circumstances,  as set  forth in the  Rights
         Agreement,  such Rights will be evidenced by separate  certificates and
         will no longer be evidenced by this certificate.  The Rights (i) may be
         redeemed at a  redemption  price  (subject to  adjustment)  of $.01 per
         Right or (ii) under certain circumstances,  may be exchanged,  in whole
         or in part,  for shares of Common  Stock of the  Company at an exchange
         rate  (subject to  adjustment)  of one share of Common Stock per Right,
         all as set forth in the Rights Agreement.  Under certain circumstances,

         Restricted Person (as such terms are defined in the Rights  Agreement),
         or by  specified  transferees  from a  Restricted  Person,  shall be or
         become void."

Each stock certificate  containing the foregoing  legend,  until the earliest of
the Distribution  Date, the Redemption Date and the Final Expiration Date, shall
be deemed also to constitute a certificate  for the Rights  associated  with the
shares represented  thereby, and the registered holder of such shares shall also
be the  registered  holder of the associated  Rights.  Until the earliest of the
Distribution  Date,  the  Redemption  Date and the Final  Expiration  Date,  the
surrender for transfer of any such stock  certificate  shall also constitute the
transfer of the Rights  associated  with the shares of Common Stock  represented
thereby. The omission of the foregoing legend shall not in any manner whatsoever
affect the application or interpretation of Section 7(d).

                  (d) In the event that the Company  shall  reacquire any shares
of its Common  Stock after the Record Date and prior to the  Distribution  Date,
the Rights  associated  with such shares shall be deemed  cancelled and retired,
the Company not being entitled to exercise any Rights  associated with shares of
its Common Stock which are no longer outstanding.

                  Section  4.  Form  of  Rights  Certificates.  (a)  The  Rights
Certificates  (including the Form of Election to Purchase and  Certification  of
Status and the Form of Assignment  and Cer  tification of Status to be set forth
on the reverse side thereof) shall be in substantially  the form attached hereto
as Exhibit B and may have such marks of  identification  or designation and such
legends,  summaries or  endorsements  set forth  thereon as the Company may deem
appropriate and are not inconsistent  with the provisions of this Agreement,  or
as may be  required  to  conform to  customary  practice  or to comply  with any
applicable law or any rule or regulation made pursuant  thereto or with any rule
or regulation of any stock exchange on which the Rights may from time to time be
listed.  Subject  to  Sections  11 and 22,  the  Rights  Certificates,  whenever
distributed,  shall be dated as of the  Record  Date (or,  in the case of Rights
with respect to shares of Common Stock issued or becoming  outstanding after the
Record Date,  the same date as the stock  certificate  evidencing  such shares),
shall (if the Company shall so require) indicate the date of countersignature by
the Rights Agent and shall  entitle the holders  thereof to purchase such number
of one one-hundredths of a Preferred Share at the Exercise Price as shall be set
forth therein,  but the number of such one  one-hundredths  of a Preferred Share
and the Exercise Price shall be subject to adjustment as provided herein.

                  (b) Any Rights  Certificate issued pursuant to Section 3(a) or
Section  22 that  represents  Rights  Beneficially  Owned by:  (i) a  Restricted
Person,  (ii) a  transferee  from a  Restricted  Person who becomes a transferee
after the Acquiring  Person or Adverse Person becomes such or (iii) a transferee
from a Restricted  Person who becomes a transferee prior to or concurrently with
the Acquiring  Person or Adverse  Person  becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for  consideration)  from such
Acquiring  Person or Adverse  Person (or any Affiliate or Associate  thereof) to
holders of equity  interests in such Acquiring  Person or Adverse Person (or any
such Affiliate or Associate) or to any Person with whom such Acquiring Person or
Adverse Person (or any such  Affiliate or Associate) has any continuing  written
or oral agreement, arrangement or understanding regarding the transferred Rights
or (B) a transfer which the Board has determined is part of a plan,  arrangement
or  understanding  which has as a primary  purpose  or effect the  avoidance  of
Section 7(d), and any Rights  Certificate issued pursuant to Section 6, 11 or 22
upon the  transfer,  exchange,  replacement  or  adjustment  of any other Rights
Certificate  referred to in this  sentence,  shall have  deleted  therefrom  the
second sentence of the legend on the Form of Rights Certificate  attached hereto
as Exhibit B and, in lieu thereof, shall contain the following two sentences:



                                      -10-

<PAGE>

                  "The Rights represented by this Rights Certificate are or were
         Beneficially  Owned by a Restricted  Person (as such term is defined in
         such  Agreement).  This Rights  Certificate and the Rights  represented
         hereby  shall be or become void under the  circumstances  specified  in
         Section 7(d) of such Agreement."

The Company shall give prompt  written notice to the Rights Agent after becoming
aware of the existence  and identity of any  Restricted  Person.  The failure to
insert the  foregoing  sentences  on any such Rights  Certificate  or any defect
therein  shall  not  in  any  manner   whatsoever   affect  the  application  or
interpretation of Section 7(d). The Company shall specify to the Rights Agent in
writing which Rights Certificates are to be so legended.

                  Section 5.  Countersignature and Registration.  (a) The Rights
Certificates  shall be executed on behalf of the Company by its  Chairman of the
Board,  its  President,  any of its  Vice  Presi  dents,  its  Treasurer  or its
Secretary,  either manually or by facsimile  signature.  The Rights Certificates
shall be manually  countersigned by an authorized  signatory of the Rights Agent
and shall not be valid or obligatory for any purpose  unless so coun  tersigned.
In  case  any  officer  of the  Company  who  shall  have  executed  any  Rights
Certificate  shall cease to be such  officer of the  Company  before such Rights
Certificate  shall have been  countersigned  by an  authorized  signatory of the
Rights  Agent and  issued and  delivered  by or on behalf of the  Company,  such
Rights Certificate,  nevertheless,  may be countersigned by the Rights Agent and
issued  and  delivered  by or on behalf of the  Company  with the same force and
effect as though the  individual  who executed such Rights  Certificate  had not
ceased to be such officer;  and any Rights Certificate may be executed on behalf
of the Company may be attested by any individual who, at the actual date of such
execution or attestation,  shall be a proper officer of the Company, although at
the date of  execution  of this  Rights  Agreement  such  person was not such an
officer.

                  (b) After the  Distribution  Date, the Rights Agent shall keep
or cause  to be kept,  at its  principal  office,  books  for  registration  and
transfer of the Rights Certificates issued hereunder.  Such books shall show the
names and addresses of the respective  holders of the Rights  Certificates,  the
number of Rights evidenced on its face by each Rights  Certificate,  the date of
each  Rights   Certificate  and  (if  required  by  the  Company)  the  date  of
countersignature by the Rights Agent.

                  Section 6.  Transfer,  Split Up,  Combination  and Exchange of
Rights Certificates;  Mutilated,  Destroyed, Lost or Stolen Rights Certificates.
(a) Subject to Sections 4(b), 7(d)

and 14, at any time after the Close of  Business on the  Distribu  tion Date and
prior to the Close of  Business on the  earlier of the  Redemption  Date and the
Final Expiration Date, any Rights Certificate (other than any Rights Certificate
which shall have been  exchanged  pursuant  to Section  24) may be  transferred,
split up,  combined  or  exchanged  for one or more other  Rights  Certificates,
entitling   the   registered   holder  to  purchase   the  same  number  of  one
one-hundredths   of  a  Preferred  Share  (or  after  a  Triggering  Event,  the
securities,  cash and other property  purchasable in lieu thereof) as the Rights
Certificate or Rights Certificates  surrendered  entitled such registered holder
to purchase.  Any registered  holder desiring to transfer,  split up, combine or
exchange  one or more Rights  Certificates  shall make such request in a writing
delivered to the Rights Agent, and shall surrender the Rights Certificates to be
transferred,  split up,  combined or exchanged,  with the Form of Assignment and
Certification of Status on the reverse side thereof duly executed, together with
such  signature  guarantees  and other  documentation  as the  Rights  Agent may
reasonably request,  at the principal office of the Rights Agent.  Thereupon the
Company shall prepare and execute,  the Rights Agent shall  countersign  and the
Company shall  deliver or cause to be delivered  (or the Rights Agent shall,  if
requested,   deliver)  to  the  Person  entitled  thereto  one  or  more  Rights
Certificates  as  so  requested.  The  Company  may  require  payment  of a  sum
sufficient  to cover  any tax or  governmental  charge  that may be  imposed  in
connection with any transfer, split up, combination or exchange of Rights Certif
icates and  reimbursement  to the Company and the Rights Agent of all reasonable
expenses incidental thereto.

                  (b)  Upon  receipt  by the  Company  and the  Rights  Agent of
evidence  reasonably  satisfactory  to them of the loss,  theft,  destruction or
mutilation  of a  Rights  Certificate,  and,  in the  case  of  loss,  theft  or
destruction, of indemnity or security reasonably satisfactory to them or, in the
case of mutilation,  upon surrender to the Rights Agent of the mutilated  Rights
Certificate, and, at the Company's request, reimbursement to the Company and the
Rights Agent of all reasonable expenses  incidental  thereto,  the Company shall
prepare and execute,  the Rights Agent shall  countersign  and the Company shall
deliver or cause to be  delivered  (or the Rights  Agent  shall,  if  requested,
deliver) to the registered holder thereof a new Rights Certificate of like tenor
in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

                  Section 7.  Exercise of Rights;  Exercise  Price;  Expira tion
Date of Rights. (a) Subject to Section 7(d), the registered holder of any Rights
Certificate  may  exercise  the Rights  evidenced  thereby  (except as otherwise
provided herein),



                                      -12-

<PAGE>

in whole or in part,  at any time after the  Distribution  Date and prior to the
earliest  of (i) the  Close  of  Business  on  December  30,  2006  (the  "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 (the  "Redemption  Date") and (iii) the time at which such Rights are
exchanged as provided in Section 24, upon surrender of such Rights  Certificate,
with the Form of Election to Purchase and Certification of Status on the reverse
side thereof duly executed,  together with such  signature  guarantees and other
documentation as the Rights Agent may reasonably request, to the Rights Agent at
its principal  office,  accompanied by payment (as provided in subsection (c) of
this Section 7) of the Exercise Price for each one  one-hundredth of a Preferred
Share (or after a Triggering  Event,  the  securities,  cash and other  property
purchasable in lieu thereof) as to which the  surrendered  Rights are then being
exercised.

                  (b)  The   price   (the   "Exercise   Price")   for  each  one
one-hundredth  of a Preferred  Share purchased upon exercise of the Rights shall
initially  be  $50.00,  shall be  subject  to  adjustment  from  time to time as
provided  in  Sections  11 and 13 and shall be  payable  in lawful  money of the
United States of America in accordance with subsection (c) of this Section 7.

                  (c) Upon  receipt of a Rights  Certificate  representing  then
exercisable  Rights,  with the Form of Election to Purchase and Certification of
Status on the reverse side thereof duly  executed,  together with such signature
guarantees and other  documentation as the Rights Agent may reasonably  request,
accom  panied  by  payment  of  the  Exercise   Price  for  the  number  of  one
one-hundredths   of  a  Preferred  Share  (or  after  a  Triggering  Event,  the
securities,   cash  and  other  property  purchasable  in  lieu  thereof)  being
purchased,  plus the amount of any applicable transfer tax (as determined by the
Rights Agent)  required to be paid by the holder of such Rights  Certificate  in
accordance  with  Section 9, by  certified  or  cashier's  check or money  order
payable to the order of the  Company,  the Rights  Agent  shall,  subject to the
terms and conditions of this Agreement,  thereupon promptly (i) requisition from
any transfer  agent for the Preferred  Shares (or, if the Rights Agent is such a
transfer  agent,  make  available)  stock  certificates  for the  number  of one
one-hundredths  of  a  Preferred  Share  being  purchased,  the  Company  hereby
irrevocably  authorizing  any  such  transfer  agent  to  comply  with  all such
requests,  (ii) if the Company  shall have  elected  that the  Preferred  Shares
issuable  upon  exercise  of the  Rights  shall be held by a  depository  agent,
requisition from the depository agent depository  receipts for the number of one
one-hundredths  of a  Preferred  Share  being  purchased  (in which  case  stock
certificates  for the Preferred Shares  represented by such depository  receipts
shall be deposited by the transfer agent for



                                      -13-

<PAGE>

the Preferred Shares with the depository  agent), the Company hereby irrevocably
authorizing  any such depository  agent to comply with all such requests,  (iii)
after a Triggering Event,  requisition or obtain from the appropriate  Person or
Persons such  securities,  cash and other property as may then be purchasable in
lieu of Preferred Shares,  the Company hereby  irrevocably  authorizing all such
requests, (iv) when appropriate, requisition from the Company the amount of cash
to be paid in lieu of the issuance of any  fractional  share in accordance  with
Section 14 and (v) promptly after receipt of such stock certificates, depository
receipts, securities, cash and/or other property, cause the same to be delivered
to or upon the  order  of the  registered  holder  of such  Rights  Certificate,
registered (when appropriate) in such name or names as may be designated by such
registered holder.

                  (d)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  from and after the first  occurrence of any Section  11(a)(ii) Event,
any Rights  Beneficially  Owned by: (i) a Restricted  Person,  (ii) a transferee
from a Restricted  Person who becomes a transferee after the Acquiring Person or
Adverse Person becomes such or (iii) a transferee  from a Restricted  Person who
becomes a  transferee  prior to or  concurrently  with the  Acquiring  Person or
Adverse Person  becoming such and receives such Rights  pursuant to either (A) a
transfer  (whether  or not for  consideration)  from  such  Acquiring  Person or
Adverse  Person (or any  Affiliate  or  Associate  thereof) to holders of equity
interests in such  Acquiring  Person or Adverse Person (or any such Associate or
Affiliate) or to any Person with whom such  Acquiring  Person or Adverse  Person
(or any  such  Associate  or  Affiliate)  has  any  continuing  written  or oral
agreement,  arrangement or understanding regarding the transferred Rights or (B)
a transfer  which the Board has  determined  is part of a plan,  arrangement  or
understanding  which has as a primary  purpose or effect the  avoidance  of this
Section 7(d) shall be or become void without any further  action;  and no holder
of such Rights  shall have any rights  whatsoever  with  respect to such Rights,
whether under any provision of this Agreement or otherwise,  from and after such
first  occurrence.  The Company shall use all reasonable  efforts to ensure that
the  provisions  of this Section 7(d) and Section  4(b) are complied  with,  but
shall have no  liability to any holder of a Rights  Certificate  or to any other
Person as a result of the Company's  failure to make any  applicable  finding or
determination   with  respect  to  any  Restricted  Person,  or  any  transferee
therefrom.

                  (e) Notwithstanding  subsection (a) of this Section 7, a Right
may be exercised  by the holder  thereof on or after the  Distribution  Date and
prior to the receipt of the  associated  Rights  Certificate  by  notifying  the
Rights Agent in writing and



                                      -14-

<PAGE>

furnishing to the Rights Agent such information and evidence as to such election
as the Rights Agent may reasonably request; pro vided,  however, that the Rights
Agent shall not be required to take any of the actions  specified in  subsection
(c) of this  Sec  tion 7 until  such  holder  shall  have  fully  satisfied  the
applicable requirements specified therein.

                  (f)  Neither  the  Rights  Agent  nor  the  Company  shall  be
obligated  to  undertake  any  action  with  respect  to any  Rights  or  Rights
Certificate  upon  the  purported  exercise  or  transfer  there of  unless  the
registered  holder thereof shall have (i) completed and signed the Certification
of Status  following the Form of Election to Purchase or the Form of Assignment,
as the case may be,  set forth on the  reverse  side of the  Rights  Certificate
surrendered  for such  exercise or transfer and (ii)  provided  such  additional
evidence as to the identity of the Beneficial Owner (or former Beneficial Owner)
thereof or the Affiliates or Associates  thereof as the Company shall reasonably
request.

                  (g) In case the  registered  holder of any Rights Certi ficate
shall exercise less than all of the Rights evidenced  thereby,  then, subject to
the  provisions of Section 14, a new Rights  Certificate  evidencing  the Rights
remaining  unexercised  shall  be  prepared  and  executed  by the  Company  and
countersigned and delivered by the Rights Agent to the registered holder of such
surrendered  Rights  Certificate or to such registered  holder's duly authorized
assigns.

                  Section   8.    Cancellation   and   Destruction   of   Rights
Certificates.  All Rights Certificates surrendered for the pur pose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company
or to any of its agents, be delivered to the Rights Agent for cancellation or in
cancelled form or, if surrendered to the Rights Agent, shall be cancelled by it;
and no Rights  Certificates  shall be issued in lieu thereof except as expressly
permitted by this  Agreement.  The Company shall deliver to the Rights Agent for
cancellation,  and the Rights Agent shall cancel,  any other Rights  Certificate
purchased or reacquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all cancelled Rights  Certificates to the Company
or shall, at the written request of the Company,  destroy such cancelled  Rights
Certificates  and de  liver a  certificate  of the  destruction  thereof  to the
Company.

                  Section 9. Reservation and  Availability of Preferred  Shares.
(a) The Company  covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued Preferred Shares, or any authorized
and issued Preferred Shares held in its treasury, the number of Preferred Shares



                                      -15-

<PAGE>

required to permit the exercise in full of all outstanding Rights.

                  (b) The  Company  covenants  and agrees  that it will take all
such action as may be necessary to ensure that all  Preferred  Shares  delivered
upon  exercise  of the  Rights  shall,  at the  time of  delivery  of the  stock
certificates  therefor in accordance with Section 7(c) (including the receipt of
payment of the Exercise  Price),  be duly and validly  authorized and issued and
fully paid and nonassessable.

                  (c) The Company covenants and agrees that it will use its best
efforts  to  cause,  from  and  after  such  time  as the  Rights  shall  become
exercisable,  all Preferred Shares issued or reserved for issuance to be listed,
upon official notice of issuance, on the principal national securities exchange,
if any,  on which its  Common  Stock is listed or, if the  principal  market for
Common  Stock is not on any  national  securities  exchange,  to be eligible for
quotation on the National  Association of Securities Dealers Automated Quotation
System ("NASDAQ") or any successor thereto or other comparable quotation system.

                  (d) The Company covenants and agrees that it will use its best
efforts to (i) file, as soon as practicable  after the occurrence of any Section
11(a)(ii) Event for which the  consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with Section 11(a)(iv),
or as soon as required by law after the Distribution Date, as the case may be, a
registration  statement on an  appropriate  form under the  Securities  Act with
respect to the securities  purchasable  upon exercise of the Rights,  (ii) cause
such  registration  statement to become  effective as soon as practicable  after
such  filing and (iii) cause such  registration  statement  to remain  effective
(with a prospectus  which at all times meets the  requirements of the Securities
Act)  until the  earliest  of (A) the date as of which the  Rights are no longer
exercisable  for such  securities,  (B) the  Redemption  Date and (C) the  Final
Expiration Date. The Company further covenants and agrees that it will take such
action as may be appropriate  under, and which will ensure  compliance with, the
securities  or "blue  sky" laws of such  jurisdictions  as may be  necessary  or
appropriate in connection with the exercisability of the Rights. The Company may
temporarily  suspend,  for not  more  than 90 days  after  the  applicable  date
specified in the first sentence of this  subsection (d), the  exercisability  of
the Rights in order to prepare and file such  registration  statement and permit
it to become effective and to complete such securities or "blue sky" law action.
Upon such suspension, the Company shall issue a public announcement stating that
the exercisability of the Rights has been temporarily suspended, and the Company
shall also issue



                                      -16-

<PAGE>

a public  announcement  at such  time as the  suspension  shall no  longer be in
effect. Failure of the Company to notify the Rights Agent of any such suspension
shall not affect the  effectiveness  thereof.  Notwithstanding  any provision of
this  Agreement  to the  contrary,  the Rights shall not be  exercisable  in any
jurisdiction   unless  the   requisite   qualification   or  exemption  in  such
jurisdiction  shall have been effected.  Until otherwise  notified in writing by
the  Company,  the Rights Agent may assume that each  purported  exercise of the
Rights is  permitted by this  Agreement  and by  applicable  law, and the Rights
Agent shall not be liable for acting in reliance upon such assumption.

                  (e) The Company covenants and agrees that,  subject to Section
6, it will pay when due and payable any and all federal and state original issue
or transfer taxes and charges which may be payable in respect of the issuance or
delivery of the Rights or the Rights  Certificates  or of any stock  certificate
for Preferred Shares issued upon exercise of the Rights.  The Company shall not,
however,  be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of any Rights  Certificate  to a Person other than,  or
the issuance of any stock  certificate for Preferred Shares upon exercise of any
of the Rights  represented by such Rights  Certificate in a name other than, the
registered  holder of such Rights  Certificate or to issue or deliver any Rights
Certificate  or stock  certificate  for  Preferred  Shares upon such transfer or
exercise  until any such tax shall have been paid (any such tax being payable by
the holder of such Rights Certificate at the time of surrender thereof) or until
it has been established to the Company's  reasonable  satisfaction  that no such
tax is due.

                  (f) After a Triggering Event, the provisions of this Section 9
shall apply, to the extent applicable and appropriate,  to all shares of capital
stock and other securities then purchasable upon exercise of the Rights.

                  Section 10.  Record Date of  Preferred  Share  Ownership.  The
Person in whose name any stock certificate for Preferred Shares (or Common Stock
and/or other  securities,  as the case may be) is issued upon exercise of any of
the Rights  shall for all purposes be deemed to have become the holder of record
of the Preferred  Shares (or Common Stock and/or other  securities,  as the case
may be) represented  thereby on, and such stock  certificate shall be dated, the
date  upon  which  the  Rights  Certificate  evidencing  such  Rights  was  duly
surrendered  to the Rights Agent with proper  payment of the Exercise Price (and
all applicable transfer taxes, if any); provided,  however,  that if the date of
such  surrender and payment shall be a date upon which the registry books of the
transfer agent for the Preferred Shares (or



                                      -17-

<PAGE>

Common  Stock  and/or  other  securities,  as the case may be) are closed,  such
Person shall be deemed to have become the record holder of such Preferred Shares
(or Common Stock and/or other securities, as the case may be) on, and such stock
certificate  shall be dated,  the next  succeeding  Business  Day on which  such
registry books are open.

                  Section 11.  Adjustment of Exercise Price,  Number and Kind of
Shares and Number of Rights.  The Exercise Price,  the number and kind of shares
of capital  stock for which each Right is  exercisable  and the number of Rights
outstanding  are  subject to  adjustment  from time to time as  provided in this
Section 11.

                  (a) (i) In the event that the Company  shall at any time after
the date of this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares
payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares into
a greater number of Preferred Shares, (C) combine or consolidate the outstanding
Preferred  Shares  into a smaller  number of  Preferred  Shares or (D) issue any
shares of  capital  stock of any class in a  reclassification  of the  Preferred
Shares (including any such  reclassification in connection with a combination or
merger in which the Company is the continuing or surviving corporation),  except
as otherwise  provided in this Section 11(a) and in Section  7(d),  the Exercise
Price in effect at the Close of Business on the record date for such dividend or
at the  effective  time  of  such  subdivision,  combination,  consolidation  or
reclassification,  and the number and kind of shares of capital  stock  issuable
upon  exercise  of the  Rights  at such date or time,  shall be  proportionately
adjusted so that the registered  holder of each Right  exercised after such date
or time shall be entitled to receive the aggregate  number and kind of shares of
capital stock which, if such Right had been exercised  immediately prior to such
date or time and at a time when the registry books of the transfer agent for the
Preferred  Shares were open, such registered  holder would have been entitled to
receive by reason of such dividend, subdivision,  combination,  consolidation or
reclassification; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the  aggregate  par value of
the shares of capital stock of the Company  issuable upon the exercise  thereof.
If an event  shall  occur  which  would  require an  adjustment  under both this
paragraph (i) and paragraph (ii) of this subsection (a), the adjustment provided
for in this  paragraph  (i) shall be in addition to, and shall be made prior to,
any adjustment required pursuant to such paragraph (ii).

                  (ii)  Subject to Section 24, in the event that:




                                      -18-

<PAGE>

                           (A) any Person,  either  alone or  together  with its
         Affiliates and Associates, shall become an Acquiring Person; or
                           (B) at least a majority  of the  members of the Board
         who are not officers of the Company  shall  declare any Person to be an
         Adverse  Person after (I) a  determination  by such directors that such
         Person,  either alone or together with its Affiliates  and  Associates,
         has  become  the  Beneficial  Owner  of 10% or more of the  outstanding
         shares of Common Stock of the Company and (II) a determination  by such
         directors,  after reasonable inquiry and investigation,  including such
         consultation,  if any,  with such Person as such  directors  shall deem
         appropriate,  that (x) such  Beneficial  Ownership  by such  Person  is
         intended  to cause,  is  reasonably  likely to cause or will  cause the
         Company to repurchase the shares of Common Stock  Beneficially Owned by
         such Person (and/or its  Affiliates  and  Associates) or the Company to
         take other action or enter into one or a series of related transactions
         which would provide such Person (and/or its Affiliates and  Associates)
         with short-term  financial gain under circumstances  which, at the time
         of taking  such other  action or  entering  into any such  transaction,
         would not, in the judgment of such directors,  be in the best long-term
         interests of the Company and its shareholders,  but for the actions and
         possible actions of such Person, (and/or its Affiliates and Associates)
         or (y) such Beneficial Ownership is having or reasonably likely to have
         a material adverse effect (including, but not limited to, impairment of
         the Company's  relationships  with customers or its ability to maintain
         its competitive  position) on the business or prospects of the Company;
         provided,  however,  that such directors may determine not to declare a
         Person to be an Adverse  Person if,  prior to the time that such Person
         acquired 10% or more of the then outstanding  shares of Common Stock of
         the Company,  such Person provides a written  statement of its purposes
         and  intentions in  connection  with its proposed  acquisition  of such
         shares of Common Stock, together with any other information  reasonably
         requested of such Person by such directors,  and such directors,  based
         on such written  statement and information and such further inquiry and
         investigation  as such directors  shall deem necessary or  appropriate,
         notify  such  Person  in  writing  that  such  Person  will not then be
         declared to be an Adverse  Person;  and  provided,  further,  that such
         directors may expressly condition in any manner their determination not
         to declare a Person to be an Adverse  Person in such  respects  as they
         deem  appropriate,  including,  without  limitation,  such Person's not
         acquiring  more than a specified  amount or percentage of the Company's
         then outstanding capital stock or other securities and/or such Person's
         not taking actions

         inconsistent with the purposes and intentions  disclosed in its written
         statement  provided to the Board;  then, in each such case and promptly
         following such  occurrence,  proper provision shall be made so that the
         registered  holder of each  Right,  except  as  otherwise  provided  in
         Section 7(d), shall thereafter have the right to receive, upon exercise
         thereof and payment of an amount  equal to the  product  determined  by
         multiplying  the  then  current  Exercise  Price by the  number  of one
         one-hundredths   of  a  Preferred   Share  for  which  such  Right  was
         exercisable  immediately  prior to such occurrence,  in accordance with
         this Agreement,  in lieu of Preferred  Shares,  the number of shares of
         Common Stock determined dividing such product by 50% of the Fair Market
         Value  (determined as provided in subsection (d) of this Section 11) of
         one share of Common Stock on the date of such occurrence.

                  (iii) No  delay  or  failure  by at  least a  majority  of the
members of the Board who are not  officers  of the Company to declare any Person
to be an Adverse Person shall in any way waive or otherwise  affect the power of
such directors thereafter to declare such Person to be an Adverse Person. In the
event that at least a majority of such directors  should at any time  determine,
after reasonable inquiry and investigation, including such consultation, if any,
with such Person as such  directors  shall deem necessary or  appropriate,  that
such  Person  has not met or  complied  with  any  condition  specified  by such
directors,  such directors may at any time thereafter  declare such Person to be
an Adverse Person.

                  (iv)  In  the  event  that  there  shall  not  be   sufficient
authorized  and  unissued  or  treasury  shares  of Common  Stock to permit  the
exercise  in  full of the  Rights  in  accordance  with  paragraph  (ii) of this
subsection  (a), the Company  shall take all  necessary  action to authorize and
reserve for  issuance  such number of  additional  shares of Common Stock as may
from time to time be  required  to be issued  upon the  exercise  in full of all
outstanding  Rights  and,  if  necessary,  shall use its best  efforts to obtain
shareholder  approval thereof.  Notwithstanding  the preceding  sentence,  if at
least a majority of the members of the Board shall determine that such action is
necessary  or  appropriate  and is not  contrary  to the best  interests  of the
holders of the Rights,  such directors may cause the Company, in lieu of issuing
shares of Common Stock in accordance with such paragraph (ii), to distribute, or
if a  sufficient  number of shares of  Common  Stock  cannot be issued  for such
purpose in accordance with the provisions  hereof, the Company shall distribute,
upon the exercise of each Right, cash, debt securities,  Preferred Shares, other
shares of Preferred Stock,  other property or any combination  thereof having an
aggregate



                                      -20-

<PAGE>

Fair Market Value  (determined as provided in subsection (d) of this Section 11)
equal to the Fair  Market  Value (as so  determined)  of the number of shares of
Common Stock which otherwise would have been issuable pursuant to such paragraph
(ii).  Any such  decision by a majority of the members of the Board must be made
and  publicly  announced  within 30 days  after the  occurrence  of any  Section
11(a)(ii) Event.

                  (b) In the event that the Company  shall fix a record date for
the making of any distribution to all registered  holders of Preferred Shares of
options, warrants or rights entitling them (for a period expiring not later than
45 calendar days after such record date) to subscribe for or purchase  Preferred
Shares (or shares of capital  stock of any class of the Company  having the same
(or more  favorable)  powers,  preferences  and rights as the  Preferred  Shares
("Equivalent  Preferred Shares"), or securities convertible into or exchangeable
for Preferred Shares or Equivalent  Preferred  Shares,  at a price per Preferred
Share or per  Equivalent  Preferred  Share (or having a  conversion  or exchange
price per share, in the case of securities  convertible into or exchangeable for
Preferred Shares or Equivalent Preferred Shares) less than the Fair Market Value
(determined  as provided in subsection  (d) of this Section 11) of one Preferred
Share on such record date,  the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
number of Preferred  Shares  outstanding on such record date, plus the number of
Preferred  Shares  which the  aggregate  offering  price of the total  number of
Preferred Shares and/or Equivalent Preferred Shares so to be offered (and/or the
aggregate  initial  conversion or exchange  price, in the case of convertible or
exchangeable  securities  so to be offered)  would  purchase at such Fair Market
Value,  and the  denominator  of which shall be the number of  Preferred  Shares
outstanding  on such record  date,  plus the total  number of  Preferred  Shares
and/or  Equivalent  Preferred  Shares so to be offered (and/or into or for which
the  convertible  or  exchangeable  securities  so to be offered  are  initially
convertible or exchangeable);  provided, however, that in no event shall the con
sideration  to be paid upon the exercise of one Right be less than the aggregate
par value of the  shares  of  capital  stock of the  Company  issuable  upon the
exercise thereof.  In case all or part of such subscription price may be paid in
a form other than cash,  the value of such non-cash  consideration  shall be its
Fair Market Value  (determined as provided in such  subsection  (d)).  Preferred
Shares  owned by or held for the  account  of the  Company  shall  not be deemed
outstanding for the purpose of any  computation  provided for in this subsection
(b). The adjustment  required by this subsection (b) shall be made  successively
whenever such a record date is fixed; and in the event that such distribution is
not so



                                      -21-

<PAGE>

made,  the Exercise  Price shall be adjusted to the  Exercise  Price which would
have been in effect if such record date had not been fixed.

                  (c) In the event that the Company  shall fix a record date for
the making of any  distribution  to all registered  holders of Preferred  Shares
(including any such distribution made in connection with a combination or merger
in which the Company is the continuing or surviving  corporation) of cash (other
than a regular quarterly cash dividend),  options,  warrants, rights (other than
those referred to in subsection (b) of this Section 11),  securities,  evidences
of indebtedness or other property  (excluding any dividend  payable in Preferred
Shares,  but including any dividend  payable in other shares of capital  stock),
the Exercise Price to be in effect after such record date shall be determined by
multiplying the Exercise Price in effect  immediately  prior to such record date
by a fraction, the numerator of which shall be the Fair Market Value (determined
as provided in  subsection  (d) of this  Section 11) of one  one-hundredth  of a
Preferred  Share  on such  record  date,  less  the  Fair  Market  Value  (as so
determined) of the cash, options,  warrants,  rights,  securities,  evidences of
indebtedness or other property so to be distributed and properly attributable to
one  one-hundredth  of a Preferred  Share, and the denominator of which shall be
such Fair Market  Value of one  one-hundredth  of a Preferred  Share;  provided,
however,  that in no event shall the  consideration to be paid upon the exercise
of one Right be less than the aggregate par value of the shares of capital stock
of the Company issuable upon the exercise  thereof.  The adjustment  required by
this  subsection (c) shall be made  successively  whenever such a record date is
fixed;  and in the event that such  distribution  is not so made,  the  Exercise
Price shall be adjusted to the Exercise Price which would have been in effect if
such record date had not been fixed.

                  (d) For the  purpose of any  computation  required  under this
Agreement,  "Fair Market  Value," when used with respect to Preferred  Shares or
shares of Common  Stock or other  capital  stock of any class  (collectively,  a
"Stock"),  to any  option,  warrant,  right or other  security  or  evidence  of
indebtedness  (collectively,  a "Security") or to any other  property,  shall be
determined as provided in this subsection (d):

                  (i) In the case of any  Stock or  Security  which is  publicly
         traded,  the Fair  Market  Value on any date  shall be deemed to be the
         average of the daily closing prices per share of such Stock or per unit
         of such Security for the 30 consecutive  Trading Days immediately prior
         to such date; provided, however, that in the event that the Fair Market
         Value per share of any Stock is determined during a period



                                      -22-

<PAGE>

         commencing  after  the  public  announcement  by  its  issuer  of (A) a
         dividend or  distribution on such Stock payable in shares of such Stock
         or securities convertible into or exchangeable for shares of such Stock
         or (B) a subdivision, combination, consolidation or reclassification of
         such Stock,  and ending prior to the  expiration of the 30 Trading Days
         after the ex-dividend  date for such dividend or  distribution,  or the
         record  date  for  such  subdivision,  combination,   consolidation  or
         reclassification,  then,  in each such case,  the Fair Market  Value of
         such  Stock   shall  be  properly   adjusted   to  take  into   account
         "ex-dividend" trading. The closing price for each day shall be the last
         sale price,  regular  way, or, in case no such sale shall take place on
         such day, the average of the closing bid and asked prices, regular way,
         in either case as reported in the  principal  consolidated  transaction
         reporting  system  with  respect to  securities  listed or  admitted to
         trading on the New York Stock Exchange or, if such Stock or Security is
         not listed or  admitted to trading on the New York Stock  Exchange,  as
         reported in the principal  consolidated  transaction  reporting  system
         with  respect  to  securities  listed or  admitted  to  trading  on the
         principal national  securities exchange on which such Stock or Security
         is listed or admitted  to trading;  or if such Stock or Security is not
         listed or admitted to trading on any national securities exchange,  the
         last quoted price or, if not so quoted,  the average of the last quoted
         high  bid and low  asked  prices  in the  over-the-counter  market,  as
         reported  by NASDAQ or any other  similar  system then in use; or if on
         any such day no bid for such  Stock or  Security  is quoted by any such
         organization,  the  average of the  closing  bid and asked  prices,  as
         furnished by a professional  market maker making a market in such Stock
         or Security  selected by the Board.  If during any  relevant  period no
         market  maker is making a market in such  Stock or  Security,  its Fair
         Market Value on a specified  date shall be  determined  reasonably  and
         with  utmost  good  faith to the  holders  of the  Rights by the Board;
         provided,  however,  that if at the  time of such  determination  there
         shall be an  Acquiring  Person or an Adverse  Person,  the Fair  Market
         Value of such Stock or Security on such date shall be  determined  by a
         nationally  recognized  investment  banking firm selected by the Board,
         which  determination  shall be described in a statement  filed with the
         Rights Agent and shall be binding on the Company,  the Rights Agent and
         the holders of the Rights.  The term  "Trading Day" shall mean a day on
         which the principal national securities exchange on which such Stock or
         Security is listed or  admitted to trading is open for the  transaction
         of business  or, if such Stock or Security is not listed or admitted to
         trading on any national securities exchange, a Business Day.

                  (ii)  In the  case  of any  Stock  or  Security  which  is not
         publicly  traded,  the Fair Market  Value on any date shall be the fair
         value  per  share  of  such  Stock  or per  unit of  such  Security  as
         determined  reasonably and with utmost good faith to the holders of the
         Rights by the  Board;  provided,  however,  that if at the time of such
         determination  there shall be an Acquiring Person or an Adverse Person,
         the Fair  Market  Value of such Stock or Security on such date shall be
         determined by a nationally  recognized investment banking firm selected
         by the Board,  which  determination  shall be  described in a statement
         filed with the Rights  Agent and shall be binding on the  Company,  the
         Rights Agent and the holders of the Rights.

                  (iii)  In the case of any  property  which is not a Stock or a
         Security,  the  Fair  Market  Value on any  date  shall  be  determined
         reasonably  and with  utmost good faith to the holders of Rights by the
         Board;  provided,  however,  that if at the time of such  determination
         there  shall be an  Acquiring  Person or an  Adverse  Person,  the Fair
         Market  Value of such  property on such date shall be  determined  by a
         nationally  recognized  investment  banking firm selected by the Board,
         which  determination  shall be described in a statement  filed with the
         Rights Agent and shall be binding on the Company,  the Rights Agent and
         the holders of the Rights.

                  (e) No  adjustment  in the  Exercise  Price shall be re quired
unless such adjustment  would require an increase or de crease of at least 1% in
the Exercise Price then in effect; provided, however, that any adjustments which
by reason of this  subsection  (e) are not  required to be made shall be carried
forward and taken into account in any subsequent  adjustment.  All  calculations
under this  Section 11 shall be made to the nearest  whole cent,  to the nearest
one  ten-thousandth  of a share of Common  Stock or other  capital  stock of any
class (other than  Preferred  Shares) or to the nearest one  one-millionth  of a
Preferred Share, as the case may be.  Notwithstanding the first sentence of this
subsection  (e),  any  adjustment  required by this  Section 11 shall be made no
later than the  earliest  of (i) three  years  after the date of the  occurrence
requiring  such  adjustment,  (ii) the  Redemption  Date  and  (iii)  the  Final
Expiration Date.

                  (f) If as a result of an adjustment required by any Triggering
Event the holder of any Rights  thereafter  exercised  shall become  entitled to
receive  any shares of capital  stock of any class of the  Company  (other  than
Preferred  Shares),  the number of such other shares so receivable upon exercise
of any Rights shall be subject to adjustment  from time to time in a man ner and
on terms as nearly equivalent as reasonably possible to

                                      -24-

<PAGE>

the provisions  with respect to the Preferred  Shares  contained in this Section
11,  and the  provisions  of  Sections  7, 9, 10, 13 and 14 with  respect to the
Preferred Shares shall apply on like terms to any such other shares.

                  (g) All Rights originally issued by the Company subse quent to
any adjustment  made to the Exercise Price hereunder shall evidence the right to
purchase,  at the adjusted Exercise Price, the number of one one-hundredths of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                  (h)  Unless  the  Company  shall  have  exercised  the  option
provided in  subsection  (i) of this  Section 11,  upon each  adjustment  of the
Exercise Price as a result of the calculations required by subsection (b) or (c)
of this Section 11, each Right  outstanding  immediately  prior to the making of
such Exercise Price adjustment shall thereafter  evidence the right to purchase,
at the adjusted Exercise Price, the number of one  one-hundredths of a Preferred
Share  (calculated  to  the  nearest  one  one-  millionth)  determined  by  (i)
multiplying the number of one  one-hundredths  of a Preferred Share  purchasable
upon exercise of such Right immediately prior to such adjustment by the Exercise
Price in effect  immediately  prior to such  adjustment  and (ii)  dividing  the
product so  obtained  by the  Exercise  Price in effect  immediately  after such
adjustment.

                  (i) The Company  may elect,  on or after the date on which any
adjustment of the Exercise Price is required to be made hereunder, to adjust the
number of Rights  outstanding  in  substitution  for making an adjustment in the
number of one  one-hundredths  of a Preferred Share purchasable upon exercise of
each Right.  Each Right  outstanding  after such an  adjustment in the number of
Rights  shall be  exercisable  for the same  number of one  one-hundredths  of a
Preferred  Share as such Right was  exercisable  for  immediately  prior to such
adjustment;  but each Right held of record prior to such adjustment shall become
the number of Rights (calculated to the nearest one  ten-thousandth)  determined
by dividing the Exercise  Price in effect  immediately  prior to the  occurrence
requiring the  adjustment of the Exercise  Price by the Exercise Price in effect
immediately  after such adjustment of the Exercise Price. The Company shall make
a prompt  public  announcement  of its  election  to adjust the number of Rights
outstanding,  indicating the record date for the adjustment and, if known at the
time of such announcement,  the amount of the adjustment to be made. Such record
date may be the date on which the  Exercise  Price is required to be adjusted or
any day there after,  unless the Rights  Certificates shall have been issued, in
which  case such  record  date  shall be at least 10 days after the date of such
public announcement. If the Rights Certificates

                                      -25-

<PAGE>

shall have been issued, upon each adjustment of the number of Rights outstanding
pursuant to this  subsection (i), the Company shall, as promptly as practicable,
cause to be distributed to each registered holder of the Rights  Certificates on
such  record  date Rights  Certificates  evidencing,  subject to Section 14, the
additional  Rights to which such registered holder shall be entitled as a result
of such adjustment; or, at its option, the Company shall cause to be distributed
to each such registered  holder,  in substitution and replacement for the Rights
Certif  icates  held  by  such  registered  holder  prior  to the  date  of such
adjustment, but only upon surrender thereof (if so required by the Company), new
Rights  Certificates  evidencing all the Rights to which such registered  holder
shall be entitled  after such  adjustment.  Rights  Certificates  so distributed
shall be executed and countersigned in the manner provided in Section 5 (and may
designate,  at the option of the Company, the adjusted Exercise Price) and shall
be registered in the names of the registered holders of the Rights  Certificates
on the record date specified in the aforesaid public announcement.

                  (j)  Irrespective  of any adjustment or change in the Exercise
Price or the number of one  one-hundredths  of a Preferred  Share  issuable upon
exercise of the  Rights,  the Rights  Certificates  theretofore  and  thereafter
issued  may  continue  to  designate  the  Exercise  Price and the number of one
one-hundredths  of a  Preferred  Share  which  were  designated  in  the  Rights
Certificates originally issued hereunder.

                  (k) Before  taking any action which would cause an ad justment
reducing the Exercise Price below one  one-hundredth  of the then par value,  if
any, of the Preferred  Shares issuable upon exercise of the Rights,  the Company
shall take any  corporate  action which may, in the opinion of its  counsel,  be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Exercise Price.

                  (l) In any case in which  this  Section  11 shall  require  an
adjustment  of  the  Exercise  Price  effective  as of  the  record  date  for a
particular  event,  the Company may elect to defer until the  occurrence of such
event the issuing to the holder of any Rights  exercised  after such record date
of the Preferred Shares (and/or the other shares of capital stock, securities or
other property of the Company,  if any) issuable upon such exercise in excess of
the Preferred  Shares (and/or the other shares of capital  stock,  securities or
other property of the Company,  if any) issuable upon such exercise on the basis
of the Exercise Price in effect immediately prior to such adjustment;  provided,
however, that the Company shall deliver to such holder a due bill

                                      -26-

<PAGE>

or other appropriate  instrument  evidencing such holder's right to receive such
excess upon the occurrence of such event.

                  (m)   Anything  in  this   Section  11  to  the  contrary  not
withstanding,  the Board shall be entitled to make  reductions  in the  Exercise
Price, in addition to the adjustments  expressly required by this Section 11, as
and to the extent that the Board, in its sole discretion,  shall determine to be
advisable  in  order  that any  dividend  on the  Preferred  Shares  payable  in
Preferred Shares, any subdivision, combination or consolidation of the Preferred
Shares  (by  reclassification  or  otherwise  than by payment  of  dividends  in
Preferred  Shares)  into a greater or lesser  number of  Preferred  Shares,  any
issuance of Preferred  Shares solely for cash at less than the Fair Market Value
thereof, any issuance solely for cash of Preferred Shares or securities which by
their terms are  convertible  into or exchangeable  for Preferred  Shares or any
issuance of options, warrants, rights, securities,  evidences of indebtedness or
other property  subject to subsection  (b) or (c) of this Section 11,  hereafter
made by the Company to the holders of the Preferred Shares, shall not be taxable
to such holders.

                  (n) In the event that the Company  shall at any time after the
date of this Agreement and prior to the Distribution Date (i) declare a dividend
on its  outstanding  shares of Common Stock payable in shares of Common Stock or
(ii) effect a  subdivision,  combination  or  consolidation  of its  outstanding
shares of Common  Stock (by  reclassification  or  otherwise  than by payment of
dividends in shares of Common  Stock) into a greater or lesser  number of shares
of Common Stock,  then, in each such case: (i) the number of one  one-hundredths
of a Preferred Share  purchasable  after such event upon proper exercise of each
Right shall be determined by multiplying the number of one  one-hundredths  of a
Preferred  Share so purchasable  immediately  prior to such event by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock  outstanding  immediately  after such event;  and (ii)
each share of Common Stock  outstanding  immediately after such event shall have
issued with  respect to it the same number of Rights  which each share of Common
Stock outstanding immediately prior to such event had issued with respect to it.
The  adjustment  required  by this  subsection  (n)  shall be made  successively
whenever  such a dividend  is  declared or such a  subdivision,  combination  or
consolidation is effected.

                  (o) Except as  permitted  by  Sections  23 and 27, the Company
covenants  and agrees that,  after the  Distribution  Date, it will not take, or
permit any of its  Subsidiaries  to take,  any action if at the time such action
would be taken it is reasonably

                                      -27-

<PAGE>

foreseeable  that such action  would  eliminate  or  substantially  diminish the
benefits intended to be afforded by the Rights.

                  Section 12.  Certificate of Adjusted  Exercise Price or Number
of Shares.  Whenever any adjustment  shall be required by Sections 11 or 13, the
Company shall promptly (i) prepare a cer tificate  setting forth such adjustment
and a brief statement of the facts requiring such adjustment, (ii) file with the
Rights Agent and with each transfer agent for the Preferred Shares or the Common
Stock of the Company a copy of such  certificate  and (iii) mail a brief summary
thereof to each  registered  holder of the Rights in accordance with Section 26.
The Rights Agent shall be fully protected in relying on any such certificate and
on any adjustment described therein and shall not be deemed to have knowledge of
any such adjustment unless and until it shall have received such certificate.

                  Section  13.  Consolidation,  Merger  or Sale or  Transfer  of
Assets or Earning  Power.  (a) In the event that, on or after the  occurrence of
any Section  11(a)(ii)  Event,  directly or indi rectly:  (i) the Company  shall
consolidate  with, or merge with and into, any Interested  Shareholder or, if in
such  consolidation or merger all holders of the Common Stock of the Company are
not treated the same, any other Person (other than a wholly-owned  Subsidiary of
the Company in a  transaction  not  prohibited  by Section  11(o)),  so that the
Company  shall  not  be  the  continuing  or  surviving  corporation,  (ii)  any
Interested  Shareholder or, if in such merger all holders of the Common Stock of
the  Company  are  not  treated  the  same,  any  other  Person  (other  than  a
wholly-owned  Subsidiary  of the  Company in a  transaction  not  prohibited  by
Section 11(o)) shall merge with and into the Company,  so that the Company shall
be the continuing or surviving  corporation,  and in connection with such merger
either (A) all or part of the outstanding  shares of Common Stock of the Company
shall be  converted  or changed  into or  exchanged  for capital  stock or other
securities of any other Person (or the Company),  cash and/or other  property or
(B) such  shares of Common  Stock  shall  remain  outstanding,  unconverted  and
unchanged, or (iii) the Company shall sell or otherwise transfer (or one or more
of its Subsid  iaries shall sell or otherwise  transfer),  in one or a series of
related  transactions,  assets or earning power  aggregating  50% or more of the
assets or earning power of the Company and its  Subsidiaries  (taken as a whole)
to any Interested  Shareholder or, if in such  transaction or  transactions  the
holders of the Common  Stock of the Company are not treated the same,  any other
Person or Persons  (other  than the  Company or one or more of its  wholly-owned
Subsidiaries  in one or more  transactions,  each of which is not  prohibited by
Section 11(o)),  then, in each such case, proper provision shall be made so that

Right,  except as otherwise  provided in Section 7(d), shall thereafter have the
right to receive,  upon  exercise  thereof and payment of an amount equal to the
product  determined by multiplying the then current Exercise Price by the number
of one  one-hundredths  of a  Preferred  Share  for  which  such  Right  is then
exercisable, in accordance with this Agreement, in lieu of Preferred Shares, the
number  of freely  tradable  shares  (which  shall be duly  authorized,  validly
issued,  fully paid and  non-assessable)  of Common Stock of the Principal Party
or, in the case of a merger  described in clause (ii) of this  sentence in which
the Common  Stock of the  Company  shall  remain  outstanding,  unconverted  and
unchanged,  of the  Company,  free  and  clear  of all  rights  of call or first
refusal,  liens,  encumbrances or other adverse  claims,  determined by dividing
such product by 50% of the Fair Market Value  (determined as provided in Section
11(d))  of  the  shares  of  Common  Stock  of  such  Principal  Party  (or,  if
appropriate,  the Company) on the date of consummation of such Section 13 Event;
(x) such Principal  Party shall  thereafter be liable for, and shall assume,  by
reason of the  consummation  of such Section 13 Event,  all the  obligations and
duties of the Company under this  Agreement;  (y) the term "Company" shall there
after be  deemed  to refer  to such  Principal  Party,  it being  spe  cifically
intended that the provisions of Section 11 shall apply to such Principal  Party;
and (z) such Principal Party shall take such steps  (including,  but not limited
to, the  reservation  of a  sufficient  number of its shares of Common  Stock to
permit exercise of all outstanding Rights in accordance with this subsection (a)
and the  distribution  of cash,  debt  securities,  shares and other property in
accordance with Section  11(a)(iv))in  connection with the  consummation of such
Section 13 Event as may be necessary to assure that the provisions  hereof shall
there after be applicable, as nearly as reasonably possible, in rela tion to the
shares of Common Stock thereafter deliverable upon exercise of the Rights.

                  (b)  After  the  Distribution  Date,  the  Company  shall  not
consolidate or merge with any other Person (other than a wholly-owned Subsidiary
of the Company in a transaction  not  prohibited by Section  11(o)),  or sell or
otherwise  transfer  (or  permit  one or  more  of its  Subsidiaries  to sell or
otherwise  transfer),  in one or a series  of  related  transactions,  assets or
earning  power  aggregating  50% or more of the assets or  earning  power of the
Company and its  Subsidiaries  (taken as a whole) to any other Person or Persons
(other than the Company or one or more of its  wholly-owned  Subsidiaries in one
or more transactions,  each of which is not prohibited by Section 11(o)), if (i)
at the time of or immediately  after the consummation of such transaction  there
are  any  options,  warrants,  rights,  conversion  or  exchange  privileges  or
securities  outstanding  or any  written  or oral  agreements,  arrangements  or
understandings (including provisions

contained in the Company's  Restated  Articles of  Incorporation  or By-laws) in
effect  which,  as a  result  of the  consummation  of such  transaction,  would
eliminate or substantially  diminish the benefits intended to be afforded by the
Rights,  or (ii) prior to, at the time of or immediately  after the consummation
of such  transaction the  shareholders of the Person who  constitutes,  or would
constitute,  the  Principal  Party for the  purpose  of  subsection  (a) of this
Section 13 shall have received a distribution of Rights previously owned by such
Person or any of its Affiliates or Associates.

                  (c) The  Company  shall not  consummate  any  Section 13 Event
unless prior thereto (i) the Principal  Party shall have a sufficient  number of
authorized shares of its Common Stock which have not been issued or reserved for
issuance to permit the  exercise in full of the Rights in  accordance  with this
Section 13 and (ii) the Company,  the Principal  Party and each other Person who
may become the Principal  Party as a result of the  consummation of such Section
13 Event shall have  executed and  delivered to the Rights Agent a  supplemental
agreement  providing (x) for the  implementation of all the terms and conditions
set forth in this Section 13 and (y) that, as soon as practicable after the date
of such Section 13 Event, the Principal Party, at its own expense, shall:

                   (A)  prepare  and  file  a   registration   statement  on  an
         appropriate  form under the  Securities  Act with respect to the Rights
         and the securities  purchasable upon exercise thereof, and use its best
         efforts to cause such  registration  statement  to become  effective as
         soon as practicable  after such filing and to remain  effective (with a
         prospectus  which at all times meets the requirements of the Securities
         Act)  until  the  earliest  of the date as of which the  Rights  are no
         longer  exercisable  for such  securities,  the Redemption Date and the
         Final Expiration Date;

                   (B) use its best  efforts to qualify or  register  the Rights
         and  the  securities   purchasable  upon  exercise  thereof  under  the
         securities or "blue sky" laws of such jurisdictions as may be necessary
         or appropriate in connection with the exercisability of the Rights;

               (C) use its best efforts to list (or continue the listing of) the
         Rights  and the  securities  purchasable  upon  exercise  thereof  on a
         national  securities  exchange or to meet the eligibility  requirements
         for quotation on NASDAQ; and

                   (D)      deliver to the registered holders of the Rights
         historical financial statements for the Principal Party and

                                      -30-

<PAGE>

         each of its  Affiliates  complying  in all material  respects  with the
         requirements  for  registration  of  securities  on Form 10  under  the
         Exchange Act.

                  (d)  "Principal   Party"  shall  mean:  in  the  case  of  any
transaction  described in clause (i) or (ii) of  subsection  (a) of this Section
13, the Person which is the issuer of the securities into which shares of Common
Stock of the Company are being  converted or changed in such  transaction or, if
there shall be more than one such  issuer,  the issuer  having  shares of Common
Stock with the greatest  aggregate  market value;  or if no securities are being
issued in such transaction for shares of Common Stock of the Company, the Person
which is the other party to such transaction or, if there shall be more than one
such  Person,  the  Person  having  shares of  Common  Stock  with the  greatest
aggregate market value;  and in the case of any transaction  described in clause
(iii) of such  subsection  (a),  the  Person  which is the party  receiving  the
greatest  portion of the assets or earning  power sold or otherwise  transferred
pursuant to such transaction or  transactions;  provided,  however,  that in any
such case (i) if the shares of Common Stock of such Person shall not at the time
of the consummation of such transaction have been continuously  registered under
Section 12 of the Exchange Act during the immediately preceding 12-month period,
and such Person shall be a direct or indirect Subsidiary or Affiliate of another
Person  the  shares  of Common  Stock of which  shall  have been so  registered,
"Principal Party" shall mean such other Person; and (ii) if such Person shall be
a direct or indirect  Subsidiary or Affiliate of more than one other Person, the
shares of Common  Stock of two or more of which  shall have been so  registered,
"Principal  Party" shall mean  whichever of such other Persons shall have Common
Stock with the greatest  aggregate  market value; and (iii) if such Person shall
be owned,  directly  or  indirectly,  by a joint  venture  formed by two or more
Persons which are not owned,  directly or  indirectly,  by the same Person,  the
rules set forth in  clauses  (i) and (ii) of this  proviso  shall  apply to each
chain of  ownership  of any joint  venturer as though such joint  venture were a
"Subsidiary"  of all of such joint  venturers,  and the Principal  Party in each
such chain shall bear the obligations and duties set forth in this Section 13 in
the same  proportion  as their  direct or  indirect  ownership  interest in such
Person bears to the total of such ownership interests.

                  (e) If,  in the case of any  transaction  described  in clause
(iii) of subsection (a) of this Section 13, the Person or Persons to whom assets
or earning power are sold or otherwise  transferred  are  individuals,  then, in
lieu of any other payment or  distribution  required by this Section 13, and the
Company shall require as a condition to such  transaction  that,  such Person or
Persons shall pay to each holder of a Rights Certi ficate, upon its surrender to
the Rights Agent and in exchange therefor (without requiring any payment by such
holder),  cash in the amount determined by multiplying the then current Exercise
Price by the number of one one-hundredths of a Preferred Share for which a Right
is then exercisable.

                  (f) In no event shall the Rights Agent have any obligations or
duties in respect of any Section 13 Event, except as expressly set forth in this
Agreement.  The Rights Agent may rely,  and shall be fully  protected in relying
upon, a certificate  of the Company  stating that the provisions of this Section
13 have been  fulfilled.  The prior written consent of the Rights Agent shall be
required in connection with any  supplemental  agreement which alters or impairs
the rights, obligations, duties or immunities of the Rights Agent hereunder.

                  (g) The provisions of this Section 13 shall similarly apply to
successive consolidations,  mergers, sales or other transfers. In the event that
any Section 13 Event shall occur at any time after the occurrence of any Section
11(a)(ii)  Event,  the Rights which have not been  theretofore  exercised  shall
thereafter be exercisable in the manner described in this Section 13.

                  Section 14. Fractional Rights and Fractional  Shares.  (a) The
Company shall not be required to issue fractional Rights or to distribute Rights
Certificates  which evidence  fractional  Rights. If the Company shall determine
not to issue  fractional  Rights,  the  Company  shall  pay,  in lieu of issuing
fractional Rights, to the registered holders of the Rights with respect to which
fractional  Rights  would  otherwise  be issuable an amount in cash equal to the
same fraction of the Fair Market Value  (determined as provided in Section 11(d)
for the  Trading  Day  immediately  prior to the date on which  such  fractional
Rights would otherwise have been issued) of one Right.

                  (b) The  Company  shall not be  required  to issue frac tional
Preferred Shares (other than fractions which are multiples of one  one-hundredth
of a  Preferred  Share)  upon  exercise  of the  Rights or to  distribute  stock
certificates  which evidence  fractional  Preferred Shares (other than fractions
which are multiples of one  one-hundredth of a Preferred  Share). If the Company
shall determine not to issue fractional  Preferred Shares that are not multiples
of  one  one-hundredth  of a  Preferred  Share,  the  Company  shall  pay to the
registered  holders of the Rights  Certificates  at the time Rights  represented
thereby are exercised, in lieu of such fractional Preferred Shares, an amount in
cash equal to the same fraction of the Fair Market Value (determined as provided
in Section 11(d) for the Trading Day

                                      -31-

<PAGE>

immediately prior to the date of such exercise) of one one-
hundredth of a Preferred Share.

                  (c)  Following  the  occurrence  of a  Triggering  Event,  the
Company shall not be required to issue  fractions of shares of Common Stock upon
exercise of the Rights or to distribute  certificates which evidence  fractional
shares of Common  Stock.  In lieu of  fractional  shares  of Common  Stock,  the
Company shall pay to the registered  holders of Rights  Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction  of the  current  market  value of one (1) share of Common  Stock.  For
purposes of this Section 14(c),  the current market value of one share of Common
Stock shall be the  closing  price of one share of Common  Stock (as  determined
pursuant to Section  11(d)(i)  hereof) for the Trading Day immediately  prior to
the date of such exercise.

                  (d) Each holder of a Right,  by accepting the same,  expressly
waives such  holder's  right to receive or exercise any  fractional  Right or to
receive any fractional  Preferred  Share upon the exercise of such Right (except
as provided in this Section 14).

                  Section 15. Rights of Action.  All rights of action in respect
of this  Agreement,  other than rights of action which the Rights Agent may have
under  Sections  18 and 20, are vested in the  registered  holders of the Rights
Certificates (or, prior to the Distribution  Date, the registered holders of the
Common  Stock  of  the  Company);  and  the  registered  holder  of  any  Rights
Certificate  (or, prior to the Distribution  Date, of any stock  certificate for
shares of such Common Stock),  without the consent of the Rights Agent or of the
holder of any other Rights  Certificate (or, prior to the Distribution  Date, of
any other stock certificate for shares of Common Stock), may, on such registered
holder's own behalf and for such registered holder's own benefit,  enforce,  and
may institute and maintain any suit, action or proceeding against the Company to
enforce,  or  otherwise  act in respect of, such  registered  holder's  right to
exercise  the Rights  evidenced  by such Rights  Certificate  (or,  prior to the
Distribution Date, such stock certificate) in the manner provided in such Rights
Certif  icate and in this  Agreement.  Without  limiting the  generality  of the
foregoing  or any  remedies  available  to the  holders  of  the  Rights,  it is
specifically  acknowledged  that the registered  holders of the Rights would not
have an  adequate  remedy at law for any  breach of this  Agreement  and will be
entitled  to specific  performance  of the  obligations  and duties  under,  and
injunctive  relief  against any actual or  threatened  violations  of the obliga
tions and duties of any Person subject to, this Agreement.

                  Section 16. Agreements of Holders of Rights.  Each holder of a
Right,  by  accepting  the same,  consents  and agrees  with the Company and the
Rights Agent and with every other holder of a Right that:

                  (i)  prior  to the  Distribution  Date,  the  Rights  shall be
         transferable  only  simultaneously  and  together  with the transfer of
         shares of Common Stock of the Company;

                  (ii) after the  Distribution  Date,  the  Rights  Certificates
         shall be transferable on the registry books of the Rights Agent only if
         surrendered at the principal office of the Rights Agent,  with the Form
         of Assignment and  Certification  of Status on the reverse side thereof
         duly  executed,  together  with  such  signature  guarantees  and other
         documentation as the Rights Agent may reasonably request;

                  (iii)  subject to  Sections 6 and 7(d),  the  Company  and the
         Rights  Agent may deem and treat the  Person in whose  name any  Rights
         Certificate (or, prior to the Distribution  Date, any stock certificate
         for Common Stock of the Company) is  registered  as the absolute  owner
         thereof  and of the Rights  represented  thereby  (notwithstanding  any
         notations of ownership or other writing on such Rights  Certificate  or
         stock  certificate  made by anyone other than the Company or the Rights
         Agent) for all  purposes  whatsoever,  and  neither the Company nor the
         Rights Agent shall be affected by any notice to the contrary; and

                  (iv)  neither the Company nor the Rights  Agent shall have any
         liability  to any holder of a Right or to any other  Person  because of
         its  inability to perform any of its  obligations  or duties under this
         Agreement by reason of any applicable law, any preliminary or permanent
         injunction  or other  order,  decree  or  ruling  issued  by a court of
         competent   jurisdiction   or   by  a   governmental,   regulatory   or
         administrative   agency  or  commission  or  any  rule,  regulation  or
         executive  order  promulgated  or  enacted  by  any  such  governmental
         authority prohibiting or otherwise restraining  performance of any such
         obligation or duty; provided,  however,  that the Company shall use its
         best  efforts  to have any such  injunction,  order,  decree  or ruling
         lifted or otherwise overturned as soon as reasonably possible.

                  Section 17.  Rights Certificate Holder Not Deemed a
Shareholder.  No holder, as such, of any Rights Certificate shall

                                      -33-

<PAGE>

be  entitled  to vote,  to receive  dividends  or other  distributions  on or to
exercise any preemptive rights with respect to, or shall be deemed for any other
purpose to be the holder of,  the  Preferred  Shares or other  shares of capital
stock of any  class  of the  Company  which  may at the  time be  issuable  upon
exercise of the Rights represented  thereby; nor shall anything contained herein
or in any  Rights  Certificate  be  construed  to confer  upon the holder of any
Rights Certificate,  as such, any of the rights of a shareholder of the Company,
or any right to vote for the  election  of  directors  or upon any other  matter
submitted to shareholders at any meeting thereof, to give or withhold consent to
any corporate  action,  to receive notice of meetings or other actions affecting
shareholders  (except  as  provided  in  Section  25) or to  receive  dividends,
subscription rights or other distributions, until the Rights represented by such
Rights Certificate shall have been exercised, in whole or in part, in accordance
with the provisions hereof.

                  Section  18.  Concerning  the Rights  Agent.  (a) The  Company
covenants and agrees to pay to the Rights Agent reasonable  compensation for all
services  rendered by it hereunder and, from time to time on the written request
of the Rights  Agent,  to reimburse it for all  reasonable  expenses and counsel
fees incurred in  connection  with the  acceptance  and  administration  of this
Agreement and the  performance  of its  obligations  and duties  hereunder.  The
Company also covenants and agrees to indemnify the Rights Agent for, and to hold
it  harmless  against,  any  loss,   liability  or  expense,   incurred  without
negligence,  bad faith or willful  misconduct on its part, for any action taken,
suffered or omitted by it in connection  with the acceptance and  administration
of this Agreement and the performance of its  obligations and duties  hereunder,
including  the costs and  expenses of  defending  against any claim of liability
arising therefrom, directly or indirectly.

                  (b) The Rights  Agent  shall be  protected  and shall incur no
liability for, or in respect of, any action taken,  suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate,  stock  certificate  for  Preferred  Shares,  Common Stock or other
shares of capital  stock of the Company,  instrument  of assignment or transfer,
power  of  attorney,   endorsement,   affidavit,  notice,  direction,   consent,
certificate,  statement or other paper or document  believed by it to be genuine
and to be executed and, where necessary,  verified or acknowledged by the proper
Person or Persons.

                  Section 19.  Merger or Consolidation of the Rights
Agent.  (a) Any corporation into which the Rights Agent or any

                                      -34-

<PAGE>

successor  Rights Agent may be merged or with which it may be  consolidated,  or
any corporation  resulting from any merger or  consolidation to which the Rights
Agent  or any  successor  Rights  Agent  shall be a  party,  or any  corporation
succeeding to the shareholder services or corporate trust business of the Rights
Agent or any successor Rights Agent,  shall be the successor to the Rights Agent
under this Agreement without the execution or filing of any paper or any further
act on the part of any of the parties  hereto,  provided  that such  corporation
would be eligible for appointment as successor Rights Agent under Section 21. In
case at the time any successor  Rights Agent shall succeed to the agency created
by  this  Agreement  any  of  the  Rights  Certificates   countersigned  by  its
predecessor  Rights Agent shall not have been delivered,  such successor  Rights
Agent  may adopt the  counter  signature  of its  predecessor  Rights  Agent and
deliver the Rights Certificates so countersigned; or in case at such time any of
the Rights Certificates shall not have been countersigned, such successor Rights
Agent  may  countersign  such  Rights  Certificates  either  in the  name of its
predecessor  Rights Agent or in the name of such successor  Rights Agent; and in
all such cases,  such Rights  Certificates  shall have the full force and effect
provided therein and in this Agreement.

                  (b) In case at any time the name of the Rights  Agent shall be
changed  and at  such  time  any of the  Rights  Certificates  shall  have  been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver the Rights Certificates so countersigned; or in
case  at  such  time  any  of  the  Rights  Certificates  shall  not  have  been
countersigned,  the Rights Agent may countersign such Rights Certificates either
in its prior name or in its changed  name;  and in all such  cases,  such Rights
Certificates  shall have the full force and effect provided  therein and in this
Agreement.

                  Section  20.  Duties of the Rights  Agent.  The  Rights  Agent
undertakes  the  obligations  and  duties  imposed  by this  Agreement  upon the
following terms and  conditions,  by all of which the Company and the holders of
the  Rights  Certificates  (or,  prior  to  the  Distribution  Date,  the  stock
certificates  for Common Stock of the Company),  by accepting the same, shall be
bound,  and no implied  obligations  or duties shall be read into this Agreement
against the Rights Agent:

                  (a) The Rights  Agent may consult with legal coun sel (who may
         be legal  counsel for the  Company),  and the  written  opinion of such
         legal counsel shall be full and complete  authorization  and protection
         to the Rights Agent as to any action  taken,  suffered or omitted by it
         in good faith and in accordance with such opinion.

                                      -35-

<PAGE>

                  (b)  Whenever  in the  performance  of its  duties  under this
         Agreement  the Rights Agent shall deem it  necessary or desirable  that
         any fact or matter be proved or  established  by the  Company  prior to
         taking, suffering or omitting any action hereunder, such fact or matter
         (unless  other  evidence  in  respect  thereof  be herein  specifically
         prescribed) may be deemed to be conclusively  proved and established by
         a  certificate  executed by any one of the  Chairman of the Board,  the
         President,  any Vice  President,  the Treasurer or the Secretary of the
         Company and delivered to the Rights Agent; and such  certificate  shall
         be full and complete  authorization  and protection to the Rights Agent
         as to any  action  taken,  suffered  or  omitted by it in good faith in
         reliance upon such certificate.

                  (c) The Rights Agent shall be liable  hereunder to the Company
         and any other Person only for its own neg ligence, bad faith or willful
         misconduct.

                  (d) The Rights  Agent  shall not be liable for or by reason of
         any of the  statements of fact or recitals  contained in this Agreement
         or in the Rights Certifi cates (except its countersignature thereon) or
         be re quired to verify the same,  but all such  statements and recitals
         are and shall be deemed to have been made by the Company only.

                  (e) The Rights Agent shall not be responsible for the validity
         of this Agreement or the execution and delivery  hereof (except for its
         due  execution  hereof) or for the  validity or execution of any Rights
         Certificate (except for its  countersignature  thereon);  nor shall the
         Rights  Agent be  responsible  for any  breach  by the  Company  of any
         covenant or  condition  contained  in this  Agreement  or in any Rights
         Certificate;  nor shall the Rights Agent be responsible  for any change
         in the  exercisability  of the Rights  (including  Rights becoming void
         pursuant to Section  7(d)),  for any  adjustment  or change (or for the
         manner  or  method  of  determining  same) in the  terms of the  Rights
         (including  any  adjustment  or change in the Exercise  Price or in the
         number or kind of shares,  securities or other  property  issuable upon
         the  exercise  thereof)  required  by  Section  11, 13, 23 or 24 or for
         ascertaining the existence of facts which would require any such change
         or adjustment  (except with respect to the exercise of Rights evidenced
         by Rights  Certificates  after actual notice, in the manner provided in
         Section 12, that such change or adjustment is

                                      -36-

         required); nor shall the Rights Agent by any act hereunder be deemed to
         have made any  representation  or warranty as to the  authorization  or
         reservation  of any  Preferred  Shares or shares of Common  Stock to be
         issued  pursuant to this  Agreement or any Rights  Certificate or as to
         whether  any  Preferred  Shares or shares of Common  Stock  will,  when
         issued,   be  validly   authorized   and  issued  and  fully  paid  and
         nonassessable.

                  (f)  The  Company  agrees  that  it  will  perform,   execute,
         acknowledge   and  deliver  or  cause  to  be  per  formed,   executed,
         acknowledged  and  delivered  all such further  acts,  instruments  and
         assurances  as may  reasonably  be required by the Rights Agent for the
         carrying out or  performing  by the Rights Agent of the  provisions  of
         this Agreement.

                  (g) The Rights  Agent is hereby  authorized  and  directed  to
         accept  instructions with respect to the performance of its obligations
         and duties  hereunder  from any one of the  Chairman of the Board,  the
         President,  any Vice  President,  the Treasurer or the Secretary of the
         Company,  and to apply to such officers for advice or  instructions  in
         connection with its obligations and duties;  and the Rights Agent shall
         not be liable for any action  taken,  suffered or omitted by it in good
         faith  and in  accordance  with the  written  instructions  of any such
         officer or for any delay in acting while waiting for such instructions.

                  (h) The Rights Agent and any shareholder, director, officer or
         employee of the Rights Agent may buy,  sell or deal in the Rights or in
         any other securities of the Company (including the Preferred Shares and
         its Common Stock) or become  pecuniarily  interested in any transaction
         in which the Company (or any of its Subsidiaries) may be interested, or
         contract   with  or  lend  money  to  the   Company   (or  any  of  its
         Subsidiaries),  and may  otherwise act as fully and freely as though it
         were not the Rights  Agent under this  Agreement;  and  nothing  herein
         shall  preclude the Rights Agent from acting in any other  capacity for
         the Company, any of its Subsidiaries or any other entity.

                  (i) The  Rights  Agent may  execute  and  exercise  any of the
         rights or powers hereby vested in it or perform any of its  obligations
         or duties  hereunder  either directly or by or through its attorneys or
         agents, and the Rights Agent shall not be answerable or accountable for
         any act, default, neglect or misconduct of any such

                                      -37-

<PAGE>

         attorney  or agent or for any loss to the  Company  resulting  from any
         such act,  default,  neglect or  misconduct,  provided the Rights Agent
         exercised  reasonable care in the selection and continued employment of
         such attorney or agent.

                  (j) If, with respect to any Rights Certificate  surrendered to
         the Rights Agent for  exercise or trans fer, the Form of  Certification
         of Status  attached  to the Form of Election to Purchase or the Form of
         Assign  ment,  as the case may be,  has either  not been  completed  or
         indicates an affirmative  response to Question 1 and/or 2 thereof,  the
         Rights  Agent  shall not take any further  action  with  respect to the
         requested  exercise  or  transfer  without  first  consulting  with the
         Company.

                  (k) No provision of this  Agreement  shall  require the Rights
         Agent to expend or risk its own funds or otherwise  incur any financial
         liability in the  performance of any of its obligations or duties or in
         the  exercise  of its  rights or  powers  hereunder  if there  shall be
         reasonable  grounds  for  believing  that  repayment  of such  funds or
         adequate   indemnification  against  such  risk  or  liability  is  not
         reasonably assured.

                  Section 21.  Resignation  or Removal of the Rights Agent.  The
Rights Agent or any successor Rights Agent may resign and be discharged from its
obligations  and duties under this  Agreement  upon 30 days' prior notice to the
Company and to each transfer  agent for the Preferred  Shares and for the Common
Stock of the Company, sent by registered or certified mail, postage prepaid, and
to each registered holder of the Rights Certificates,  sent by first-class mail,
postage prepaid. The Company may remove the Rights Agent or any successor Rights
Agent upon 30 days' prior notice to the Rights Agent or successor  Rights Agent,
as the case may be, and to each transfer agent for the Preferred  Shares and for
the Common Stock of the Company,  sent by registered or certified mail,  postage
prepaid,  and to each  registered  holder of the  Rights  Certificates,  sent by
first-class mail,  postage prepaid.  If the Rights Agent or any successor Rights
Agent shall resign or be removed or shall otherwise  become incapable of acting,
the Company shall appoint a successor Rights Agent. If the Company shall fail to
make such  appointment  within 30 days after  giving  notice of such  removal or
after  receiving  notice of such  resignation  or  incapacity,  either  from the
resigning or  incapacitated  Rights Agent or from the  registered  holder of any
Rights  Certificate (who shall, with such notice,  submit its Rights Certificate
for  inspection  by  the  Company),  then  the  incumbent  Rights  Agent  or the
registered

                                      -38-

<PAGE>

holder  of  any  Rights   Certificate  may  apply  to  any  court  of  competent
jurisdiction  for the  appointment  of a successor  Rights Agent.  Any successor
Rights Agent,  whether  appointed by the Company or by such a court,  shall be a
corporation  organized and doing business under the laws of the United States of
America  or the  State  of New  York  (or of any  other  state  so  long as such
corporation  is authorized to do business as a banking  institution in the State
of New York),  be in good  standing  under the laws of the  jurisdiction  of its
incorporation, have an office in the State of New York, be authorized under such
laws to  exercise  corporate  trust or stock  transfer  powers,  be  subject  to
supervision or examination by federal or state authority and have at the time of
its  appointment  as Rights  Agent a combined  capital  and  surplus of at least
$50,000,000.  After its appointment,  the successor Rights Agent shall be vested
with the same rights,  powers,  obligations,  duties and immunities as if it had
been  originally  named as Rights  Agent  without  further act or deed;  but the
predecessor  Rights  Agent shall  deliver and transfer to the  successor  Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance,  conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such  appointment,  the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent for
the  Preferred  Shares and for the Common Stock of the Company,  and mail notice
thereof to the registered  holders of the Rights  Certificates.  Failure to give
any notice  provided for in this  Section 21,  however,  or any defect  therein,
shall not affect the legality or validity of the  resignation  or removal of the
Rights Agent or any successor  Rights Agent or the  appointment of any successor
thereto.

                  Section  22.   Issuance  of  New  Rights   Certificates.   Not
withstanding  any provision of this Agreement or of the Rights  Certificates  to
the  contrary,  the Company  may, at its option,  issue new Rights  Certificates
evidencing  the Rights in such form as may be  approved  by the Board to reflect
any  adjustment  or change  in the  Exercise  Price or in the  number or kind of
shares,  securities  or other  property  issuable upon exercise of the Rights in
accordance with the provisions of this Agreement; provided, however, that (i) no
such Rights Certificates shall be issued if, and to the extent that, the Company
shall be advised by counsel that such issuance  could create a significant  risk
of material  adverse tax  consequences  to the Company or to the Persons to whom
such Rights  Certificates  would be issued and (ii) no such Rights  Certificates
shall be issued  if, and to the  extent  that,  appro  priate  adjustment  shall
otherwise have been made in lieu of the issuance thereof.

                  Section 23.  Redemption.  (a) The Board may, at its option, at
any time prior to the earliest of (i) the Close of Business on the 10th Business
Day after the Share  Acquisition  Date (or, if the Share  Acquisition Date shall
have  occurred  prior to the  Record  Date,  the Close of  Business  on the 10th
Business  Day after the Record  Date),  (ii) the Close of  Business  on the 10th
Business  Day after the date on which at least a majority  of the members of the
Board who are not officers of the Company has declared a Person to be an Adverse
Person,  (iii)  the  occurrence  of any  Section  13 Event  and  (iv) the  Final
Expiration  Date,  redeem all,  but not less than all,  of the then  outstanding
Rights at a  redemption  price of $.01 per Right  (such  redemption  price being
hereinafter called the "Redemption Price").

                  (b) Notwithstanding any other provision of this Agreement, the
Rights  shall  not be  exercisable  after the first  occurrence  of any  Section
11(a)(ii) Event until such time as the Company's right of redemption  under this
Section 23 shall have expired.

                  (c) In considering whether to redeem the Rights, the Board may
consider  the best  long-term  and  short-term  interests of the Company and its
shareholders,  including,  without limitation,  the effects of the redemption of
the Rights upon employees,  creditors, suppliers and customers of the Company or
of its  Subsidiaries  and  upon  the  communities  in  which  offices  or  other
establishments  of the Company and such  Subsidiaries  are located and all other
pertinent  factors.  The  redemption  of the  Rights  by the  Board  may be made
effective at such time, on such basis and with such  conditions as the Board, in
its sole discretion, may establish.

                  (d)  Immediately  after  action  by the  Board  directing  the
redemption  of the Rights  pursuant to  subsection  (a) of this  Section 23, and
without any further  action and  without any notice,  the right to exercise  the
Rights shall  terminate,  and thereafter  each  registered  holder of the Rights
shall only be entitled to receive the  Redemption  Price  therefor.  The Company
shall give prompt written notice to the Rights Agent and prompt public notice to
the holders of the Rights of any such redemp tion; provided,  however,  that the
failure to give, or any defect in, any such notice shall not affect the validity
of such redemp  tion.  Within 10 days after  action by the Board  directing  the
redemption  of the Rights,  the Company shall mail (or cause the Rights Agent to
mail) a notice of redemption to each registered  holder of the then  outstanding
Rights,  at its last address appearing on the registry books of the Rights Agent
or, prior to the Distribution  Date, on the registry books of the transfer agent
for the Common  Stock of the  Company.  Any notice which is mailed in the manner
provided in this subsection (d) shall be

                                      -40-

<PAGE>

deemed  given,  whether or not received by the  registered  holder to whom sent.
Each  notice of  redemption  shall  state the  method  by which  payment  of the
Redemption Price is to be made. Neither the Company nor any of its Affiliates or
Associates  may at any time  redeem,  acquire or  purchase  for value any Rights
other  than in the  manner  set forth in this  Section  23 and  Section 24 or in
connection with any purchase of outstanding  shares of its Common Stock prior to
the Distribution Date.

                  (e) The Company may, at its option,  pay the Redemption  Price
in cash,  shares of Common Stock (based on its Fair Market Value  (determined as
provided in Section  11(d)) as of the date of  redemption)  or any other form of
consideration deemed appropriate by the Board.

                  Section 24. Exchange. (a) The Board may, at its option, at any
time on or after the occurrence of any Section 11(a)(ii) Event,  exchange all or
any part of the then outstanding and exercisable Rights (which shall not include
any Rights which have become void pursuant to Section 7(d)) for shares of Common
Stock of the Company at an exchange rate of one share of Common Stock per Right,
appropriately  adjusted  to reflect any event  specified  in clauses (A) through
(D),  inclusive,  of the first sentence of Section  11(a)(i) or in Section 11(n)
occurring after the date hereof (such exchange rate being hereinafter called the
"Exchange Rate");  provided,  however, that the Board shall not be authorized to
effect  such an  exchange  at any time  after any Person  (other  than an Exempt
Person), together with the Affili ates and Associates of such Person, shall have
become the Benefi  cial Owner of 50% or more of the then  outstanding  shares of
Common Stock of the Company.

                  (b)  Immediately  after  action  by the  Board  directing  the
exchange  of any Rights  pursuant  to  subsection  (a) of this  Section  24, and
without any further  action and without any notice,  the right to exercise  such
Rights shall  terminate,  and thereafter each  registered  holder of such Rights
shall only be entitled  to receive  the number of shares of Common  Stock of the
Company  which shall  equal the number of such  Rights  held by such  registered
holder  multiplied by the Exchange  Rate then in effect.  The Company shall give
prompt  written  notice to the  Rights  Agent and  prompt  public  notice to the
holders of the Rights of any such exchange;  provided, however, that the failure
to give, or any defect in, any such notice shall not affect the validity of such
exchange. Within 10 days after action by the Board directing the exchange of any
Rights,  the Company  shall mail (or cause the Rights Agent to mail) a notice of
exchange to each registered holder of such Rights, at its last address appearing
on the registry books of the Rights Agent or, prior to the Distribution

                                      -41-

<PAGE>

Date,  on the registry  books of the transfer  agent for the Common Stock of the
Company.  Any notice which is mailed in the manner  provided in this  subsection
(b) shall be deemed given,  whether or not received by the registered  holder to
whom sent.  Each notice of exchange shall state the method by which the exchange
of shares of Common  Stock for Rights will be effected  and, in the event of any
partial  exchange,  the number of Rights  which will be  exchanged.  Any partial
exchange shall be effected pro rata among the  registered  holders of the Rights
based upon the number of Rights held  (excluding  Rights which shall have become
void  pursuant to Section  7(d));  and, in such case,  a new Rights  Certificate
evidencing the Rights not being  exchanged shall be prepared and executed by the
Company and  countersigned  and delivered by the Rights Agent to the  registered
holder of such Rights.

                  (c) In any exchange  pursuant to this Section 24, the Company,
at its option, may substitute  Preferred Shares (or Equivalent Preferred Shares)
for shares of Common Stock in  effecting an exchange for Rights,  at the initial
rate of one  one-hundredth of a Preferred Share (or Equivalent  Preferred Share)
for  each  share  of  Common  Stock,   appropriately  adjusted  to  reflect  any
adjustments in the voting rights of the Preferred  Shares  pursuant to the terms
thereof, so that the fractional  Preferred Share delivered in lieu of each share
of Common Stock shall have the same voting rights as one share of Common Stock.

                  (d) In the event that there shall not be sufficient authorized
and  unissued  or  treasury  shares  of Common  Stock or  Preferred  Shares  (or
Equivalent  Preferred  Shares) to permit the exchange of Rights  directed by the
Board,  the Company shall take all necessary action to authorize and reserve for
issuance  such number of additional  shares of Common Stock or Preferred  Shares
(or  Equivalent  Preferred  Shares) as may be required  for  issuance  upon such
exchange  and, if  necessary,  shall use its best efforts to obtain  shareholder
approval thereof.

                  (e) The  Company  shall not be  required  to issue frac tional
shares  of  Common  Stock  in  exchange  for  Rights  or  to  distribute   stock
certificates  which evidence  fractional  shares of Common Stock. If the Company
shall  determine not to issue frac tional  shares of Common  Stock,  the Company
shall pay to the  registered  holders of the Rights  with  respect to which such
fractional  shares  would  otherwise  be issuable an amount in cash equal to the
same fraction of the Fair Market Value  (determined as provided in Section 11(d)
for the Trading Day immediately prior to the date of such exchange) of one share
of Common Stock.

                  Section  25.  Notice  to  Holders  of Rights  Certificates  of
Certain Events.  (a) In the event that at any time after the Distribution  Date,
the Company shall propose:  (i) to pay any dividend payable in shares of capital
stock of any class of the Company to the holders of Preferred  Shares or to make
any other cash  distribution  to the holders of Preferred  Shares  (other than a
regular  quarterly cash dividend);  (ii) to effect any  reclassification  of the
Preferred Shares (other than a  reclassification  involving only the subdivision
of the  outstanding  Preferred  Shares);  (iii) to make any  distribution to the
holders of Preferred  Shares  described in subsection  (b) or (c) of Section 11;
(iv) to effect any  Section 13 Event;  (v) to pay any  dividend on its shares of
Common  Stock  payable  in shares of  Common  Stock or to effect a  subdivision,
combination  or  consolidation  of its  outstanding  shares of Common  Stock (by
reclassification  or otherwise  than by payment of dividends in shares of Common
Stock);  or (vi) to effect  the  liquidation,  dissolution  or winding up of the
Company; then, in each such case, the Company shall give to the Rights Agent and
each  registered  holder of the  Rights,  in the manner  provided in Section 26,
written notice of such proposed action,  which shall specify the record date for
such stock dividend or distribution or the date on which such  reclassification,
Section 13 Event,  liquidation,  dissolution  or winding up is expected to occur
(and the date for  participation  therein by the  holders  of the  Common  Stock
and/or Preferred  Shares if any such date is to be fixed).  Such notice shall be
given,  in the  case of any  action  described  in  clause  (i) or  (iii) of the
preceding  sentence,  at least 10 days prior to the record date and, in the case
of any other such  action,  at least 20 days prior to the date of taking of such
pro  posed  action  or the date for  participation  therein  by the  holders  of
Preferred Shares, whichever shall be the earlier.

                  (b) In case any  Section  11(a)(ii)  Event  shall  occur,  the
Company shall, as soon as practicable  thereafter,  give to the Rights Agent and
each  registered  holder of the  Rights,  in the manner  provided in Section 26,
written  notice of the  occurrence  thereof,  which notice shall  describe  such
occurrence and its consequences in reasonable detail.

                  Section  26.  Other  Notices.  Except  as  otherwise  provided
herein,  notices or demands  authorized by this Agreement to be given or made by

prepaid,  addressed  (until  another  address shall be filed in writing with the

Distribution  Date, but subject to the penultimate  sentence of this Section 27,
the Company  and the Rights  Agent,  if so  directed in writing by the  Company,
shall  supplement or amend any term,  including any amendment  which changes the
Final  Expiration  Date to any earlier  date,  provision  or  condition  of this
Agreement,  without  the  approval  of  the  registered  holders  of  the  stock

desirable and which shall not adversely  affect, as determined by the Board, the
interests (however represented) of the holders (other than any Restricted Person

provided,  however,  that the Rights  Agent shall not be required to execute any

Distribution  Date,  the  interests of the holders of the Rights shall be deemed
coincident with the interests of the holders of the Common Stock of the Company.

                  Section 29. Certain  Determinations  and Actions by the Board.
For all purposes of this  Agreement,  any calculation of the number of shares of
Common Stock outstanding at any particular time,  including the determination of
the percentage of such outstanding  shares of which any Person is the Beneficial
Owner,   shall  be  made  in   accordance   with  the  last   sentence  of  Rule
13d-3(d)(1)(i),  as in effect on the date hereof,  under the  Exchange  Act. The
Board shall have the exclusive  power and authority to interpret  this Agreement
and to exercise  all rights and powers  specifically  granted to the Board or to

To the Secretary of State of the State of Iowa:

                  Pursuant  to the  provisions  of Section  490.602  and Section
409.1006 of the Iowa  Business  Corporation  Act,  the  undersigned  corporation
hereby  amends its Restated  Articles of  Incorporation,  and for that  purpose,
submits the
following statement:

         1.       The name of the Company is MidAmerican Energy
                  Holdings Company (the "Company").

         2.       On December 18, 1996, the Company adopted an
                  amendment to its Restated Articles of
                  Incorporation, the text of which is attached

                     DESIGNATION, PREFERENCES AND RIGHTS OF
                     SERIES A JUNIOR PARTICIPATING PREFERRED
                  STOCK OF MIDAMERICAN ENERGY HOLDINGS COMPANY


                  RESOLVED,  that,  pursuant to the authority conferred upon the
Board of Directors of the  Corporation  (the  "Board") by the  provisions of the
Restated Articles of  Incorporation,  as amended,  of the Corporation,  there is
hereby  created  a  series  of  Preferred  Stock,  without  par  value,  of  the
Corporation,  which series shall have the  following  designation  and number of
shares, and fixes the relative rights,  preferences,  and limitations as follows
thereof:

                  Section 1. Designation of Series; Number of Shares. The series
of Preferred Stock  established  hereby shall be designated the "Series A Junior
Participating  Preferred  Stock"  (the  "Series  A  Preferred  Stock")  and  the
authorized  number of shares  constituting the Series A Preferred Stock shall be
3,500,000.  Such number of authorized shares may be increased or decreased, from
time to time,  by  resolution  of the  Board;  provided,  however,  that no such
decrease shall reduce the number of authorized  shares of the Series A Preferred
Stock to a number less than the number of shares of the Series A Preferred Stock
then outstanding, plus the number of shares of the Series A Preferred Stock then
reserved for issuance upon the exercise of any outstanding options,  warrants or
rights or the exercise of any conversion or exchange privilege  contained in any
outstanding security issued by the Corporation.

                  Section 2.  Dividends  and  Distributions.  (A) Subject to the
rights of the holders of shares of any other series of the  Preferred  Stock (or
shares of any other class of capital stock of the Corporation) ranking prior and
superior to the Series A Preferred Stock with respect to dividends,  the holders
of shares of the Series A  Preferred  Stock,  in  preference  to the  holders of
shares  of  Common  Stock  and  of any  other  class  of  capital  stock  of the
Corporation  ranking  junior to the Series A  Preferred  Stock  with  respect to
dividends,  shall be entitled to receive,  when, as and if declared by the Board
out of funds legally available therefor,  quarterly dividends payable in cash on
the first day of March,  June,  September  and  December in each year (each such
date being a "Dividend Payment Date"),  commencing on the first Dividend Payment
Date after the initial  issuance of a share or fractional  share of the Series A
Preferred  Stock,  in an amount per share  (rounded to the  nearest  whole cent)
equal to the  greater  of (a) $.01 and (b) 100  times  the  aggregate  per share
amount of all cash  dividends,  plus 100 times the  aggregate  per share  amount
(payable in kind) of all non-cash dividends or other distributions (other than a
dividend  payable in shares of Common Stock or a distribution in connection with
the subdivision of the outstanding  shares of Common Stock, by  reclassification
or

                                       A-2

<PAGE>

otherwise),  declared  on the  Common  Stock  since  the  immediately  preceding
Dividend Payment Date or, with respect to the first Dividend Payment Date, since
the initial  issuance of a share or  fractional  share of the Series A Preferred
Stock. The multiple of 100 (the "Dividend  Multiple") set forth in the preceding
sentence  shall be adjusted  from time to time as  hereinafter  provided in this
paragraph  (A).  In the event that the  Corporation  shall at any time after the
effective  date of this Articles of Amendment (i) declare or pay any dividend on
the Common Stock payable in shares of Common Stock or (ii) effect a subdivision,
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock,  then, in each
such case, the Dividend Multiple  thereafter  applicable to the determination of
the amount of  dividends  per share  which the holders of shares of the Series A
Preferred  Stock shall be entitled to receive shall be the Dividend  Multiple in
effect  immediately prior to such event multiplied by a fraction,  the numerator
of which shall be the number of shares of Common Stock  outstanding  immediately
after such event and the  denominator  of which shall be the number of shares of
Common Stock that were outstanding immediately prior to such event.

                  (B) The Board shall  declare,  out of funds legally  available
therefor,  a dividend  or  distribution  on the  Series A  Preferred  Stock,  as
provided in paragraph (A) of this Section 2, immediately after it has declared a
dividend or distribution  on the Common Stock (other than a dividend  payable in
shares of Common Stock); provided,  however, that, in the event that no dividend
or  distribution  shall have been declared on the Common Stock during the period
between any Dividend Payment Date and the next subsequent Dividend Payment Date,
a dividend of $.01 per share on the Series A Preferred Stock shall  nevertheless
be payable on such subsequent Dividend Payment Date.

                  (C)  Dividends  shall begin to accrue and be cumulative on the
outstanding  shares of the Series A Preferred  Stock from the  Dividend  Payment
Date next  preceding  the date of issuance of such  shares,  unless such date of
issuance shall be prior to the record date for the first Dividend  Payment Date,
in which case  dividends on such shares shall begin to accrue and be  cumulative
from the date of issuance of such shares,  or unless such date of issuance shall
be after the close of business on the record date with  respect to any  Dividend
Payment  Date and on or prior  to such  Dividend  Payment  Date,  in which  case
dividends  on such  shares  shall  begin to accrue and be  cumulative  from such
Dividend  Payment Date.  Accrued but unpaid  dividends  shall not bear interest.
Dividends paid on shares of the Series A Preferred  Stock in an amount less than
the total amount of dividends then

                                       A-3

<PAGE>

accrued  shall be  allocated  pro rata  among such  shares.  The Board may fix a
record  date for the  determination  of the  holders  of shares of the  Series A
Preferred  Stock  entitled to receive  payment of any  dividend or  distribution
declared  thereon,  which  record date shall be not more than the number of days
prior to the date fixed for such payment permitted by applicable law.

                  Section 3. Voting  Rights.  In  addition  to any other  voting
rights  required  by  applicable  law,  the  holders  of shares of the  Series A
Preferred Stock shall have the following voting rights:

                  (A) Each share of the Series A Preferred  Stock shall  entitle
the  holder  thereof  to 100  votes on all  matters  submitted  to a vote of the
shareholders of the Corporation. The multiple of 100 (the "Voting Multiple") set
forth  in the  preceding  sentence  shall  be  adjusted  from  time  to  time as
hereinafter  provided in this paragraph  (A). In the event that the  Corporation
shall at any time after the  effective  date of this  Articles of Amendment  (i)
declare  or pay any  dividend  on the Common  Stock  payable in shares of Common
Stock  or (ii)  effect a  subdivision,  combination  or  consol  idation  of the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of  shares  of Common  Stock,  then,  in each such  case,  the  Voting  Multiple
thereafter  applicable to the  determination of the number of votes per share to
which the  holders of shares of the Series A  Preferred  Stock shall be entitled
shall  be the  Voting  Multiple  in  effect  immediately  prior  to  such  event
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Common Stock outstanding  immediately after such event and the denominator of
which  shall be the  number  of shares of  Common  Stock  that were  outstanding
immediately prior to such event.

                  (B)  Except  as  otherwise   provided  in  this   Articles  of
Amendment, in any other Articles of Amendment establishing another series of the
Preferred  Stock  (or any  series  of any other  class of  capital  stock of the
Corporation) or by applicable law, the holders of the Series A Preferred  Stock,
the  holders of the Common  Stock and the  holders of any other class of capital
stock of the  Corporation  having general voting rights shall vote together as a
single  class on all  matters  submitted  to a vote of the  shareholders  of the
Corporation.

                  (C) Except as otherwise provided in this Articles of Amendment
or by applicable  law, the holders of the Series A Preferred Stock shall have no
special  voting rights and their  consent  shall not be required  (except to the
extent provided

                                       A-4

<PAGE>

in paragraph (B) of this Section 3) for the taking of any
corporate action.

                  Section 4.  Certain Restrictions.

                  (A) Whenever dividends or other  distributions  payable on the
Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and
until all  accrued  and  unpaid  dividends  and  distributions,  whether  or not
declared,  on outstanding shares of the Series A Preferred Stock shall have been
paid in full, the Corporation shall not:

                      (i)  declare  or  pay  dividends,   or   make  any   other
                  distributions,  on any shares of any class of capital stock of
                  the Corporation ranking junior (either as to dividends or upon
                  liquidation,  dissolution or winding up of the Corporation) to
                  the Series A Preferred Stock;

                      (ii)  declare  or  pay   dividends,   or  make  any  other
                  distributions,  on any shares of any class of capital stock of
                  the Corporation ranking on a parity (either as to dividends or
                  upon   liquidation,   dissolution   or   winding   up  of  the
                  Corporation)  with  the  Series  A  Preferred  Stock,   except
                  dividends paid ratably on the Series A Preferred Stock and all
                  such parity stock on which dividends are accrued and unpaid in
                  proportion  to the total  amounts to which the  holders of all
                  such shares are then entitled;

                     (iii)   redeem,   purchase   or   otherwise   acquire   for
                  consideration  any shares of any class of capital stock of the
                  Corporation  ranking  junior  (either as to  dividends or upon
                  liquidation,  dissolution or winding up of the Corporation) to
                  the Series A Preferred Stock,  except that the Corporation may
                  at any time redeem,  purchase or otherwise  acquire any shares
                  of such junior stock in exchange for other shares of any class
                  of capital stock of the Corporation ranking junior (both as to
                  dividends and upon  dissolution,  liquidation or winding up of
                  the Corporation) to the Series A Preferred Stock; or

                      (iv) purchase or otherwise  acquire for  consideration any
                  shares of the  Series A  Preferred  Stock or any shares of any
                  class of capital stock of the Corporation  ranking on a parity
                  (either as to dividends or upon  liquidation,  dissolution  or
                  winding up of the  Corporation)  with the  Series A  Preferred
                  Stock,  or redeem any shares of such parity  stock,  except in
                  accordance  with  a  purchase  offer  made  in  writing  or by
                  publication (as determined by the Board) to the holders of all
                  such shares upon such terms and

                                       A-5

<PAGE>

                  conditions as the Board,  after taking into  consideration the
                  respective  annual  dividend  rates  and  the  other  relative
                  powers,  preferences  and rights of the respective  series and
                  classes of such  shares,  shall  determine  in good faith will
                  result in fair and equitable  treatment  among the  respective
                  holders of shares of all such series and classes.

                  (B) The  Corporation  shall not permit any  subsidiary  of the
Corporation to purchase or otherwise acquire for consideration any shares of any
class of capital stock of the Corporation  unless the Corporation  could,  under
paragraph  (A) of this Section 4,  purchase or otherwise  acquire such shares at
such time and in such manner.

                  Section  5.  Reacquired  Shares.  Any  shares of the  Series A
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever  shall be retired  and  cancelled  promptly  after such  purchase  or
acquisition.  All such cancelled  shares shall thereupon  become  authorized and
unissued shares of Preferred Stock and may be reissued as part of any new series
of the Preferred  Stock,  subject to the conditions and restrictions on issuance
set forth in the  Restated  Articles of  Incorporation  of the  Corporation,  as
amended  from time to time,  in any other  Articles  of  Amendment  establishing
another  series  of the  Preferred  Stock (or any  series of any other  class of
capital stock of the Corporation) or in any applicable law.

                  Section 6.  Liquidation,  Dissolution  or Winding Up. Upon any
liquidation  (whether voluntary or otherwise),  dissolution or winding up of the
Corporation,  no distribution  shall be made (a) to the holders of shares of any
class of capital stock of the Corporation ranking junior (either as to dividends
or upon liquidation, dissolution or winding up of the Corporation) to the Series
A Preferred Stock unless, prior thereto, the holder of each outstanding share of
the Series A Preferred  Stock shall have received an amount equal to the accrued
and unpaid dividends and distributions thereon,  whether or not declared, to the
date of such payment,  plus an amount equal to an aggregate  amount,  subject to
adjustment  as  hereinafter  provided in this Section 6, equal to the greater of
(i) $1.00 and (ii) 100 times the aggregate per share amount to be distributed to
the holders of the Common  Stock or (b) to the holders of shares of any class of
capital stock of the Corporation  ranking on a parity (either as to dividends or
upon liquidation,  dissolution or winding up of the Corporation) with the Series
A Preferred Stock,  except  distributions made ratably on the Series A Preferred
Stock and all such parity stock in  proportion to the total amounts to which the
holders of all such shares are entitled upon such  liquidation,  dissolution  or
winding  up.  In the  event  that the  Corporation  shall at any time  after the
effective date of this

                                       A-6

<PAGE>

Articles  of  Amendment  (a)  declare or pay any  dividend  on the Common  Stock
payable in shares of Common Stock or (b) effect a  subdivision,  combination  or
consolidation of the outstanding shares of Common Stock (by  reclassification or
otherwise  than by  payment  of a  dividend  in shares of Common  Stock)  into a
greater or lesser number of shares of Common Stock, then, in each such case, the
aggregate amount per share which the holders of shares of the Series A Preferred
Stock shall  thereafter be entitled to receive pursuant to clause (a)(ii) of the
preceding sentence shall be the aggregate amount per share in effect pursuant to
such  clause  immediately  prior to such event  multiplied  by a  fraction,  the
numerator  of which  shall be the number of shares of Common  Stock  outstanding
immediately after such event and the denominator of which shall be the number of
shares of Common Stock that were outstanding immediately prior to such event.

                  Section 7.  Consolidation,  Merger, etc. In the event that the
Corporation shall be a party to any consolidation,  merger, combination or other
transaction  in which the  outstanding  shares of Common Stock are  converted or
changed into or exchanged for other  capital  stock,  securities,  cash or other
property, or any combination thereof, then, in each such case, each share of the
Series A  Preferred  Stock  shall at the same  time be  similarly  converted  or
changed into or exchanged  for an aggregate  amount,  subject to  adjustment  as
hereinafter  provided in this Section 7, equal to 100 times the aggregate amount
of capital stock,  securities,  cash and/or other property (payable in kind), as
the case may be,  into which or for which  each  share of Common  Stock is being
converted or changed or exchanged.  In the event that the  Corporation  shall at
any time after the  effective  date of this Articles of Amendment (a) declare or
pay any dividend on the Common  Stock  payable in shares of Common Stock or (ii)
effect a subdivision,  combination or consolidation of the outstanding shares of
Common Stock (by  reclassification or otherwise than by payment of a dividend in
shares of Common  Stock)  into a  greater  or lesser  number of shares of Common
Stock, then, in each such case, the aggregate amount per share which the holders
of shares of the Series A  Preferred  Stock  shall  thereafter  be  entitled  to
receive  pursuant to the preceding  sentence  shall be the aggregate  amount per
share in  effect  pursuant  to such  sentence  immediately  prior to such  event
multiplied  by a fraction,  the numerator of which shall be the number of shares
of Common Stock outstanding  immediately after such event and the denominator of
which  shall be the  number  of shares of  Common  Stock  that were  outstanding
immediately prior to such event.

Amendment,  the  Series A  Preferred  Stock  shall  rank,  as to the  payment of
dividends and the making of any other distribution of assets of the Corporation,
senior to the  Common  Stock,  but junior to all other  series of the  Preferred
Stock.

of the  Corporation  shall not be amended in any manner  which would  materially

Stock so as to adversely  affect any thereof without the affirmative vote of the
holders  of at  least  two-thirds  of the  outstanding  shares  of the  Series A
Preferred Stock, voting separately as a single class.

determine,  only in multiples of one one-hundredth of a share. The holder of any
fractional  share of the Series A  Preferred  Stock shall be entitled to receive
dividends,  participate in  distributions,  exercise  voting rights and have the
benefit of all other  powers,  preferences  and rights  relating to the Series A
Preferred Stock in the same proportion as such fractional share bears to a whole
share.

Preferred  Share  which may be  purchased  upon the  exercise of each Right) set
forth  above,  and the Exercise  Price set forth above,  are the numbers and the

or more Rights Certificates for the number of whole Rights not exercised.

                          SUMMARY OF RIGHTS TO PURCHASE
             SHARES OF SERIES A JUNIOR PARTICIPATING PREFERRED STOCK


                           On December  18, 1996,  the Board of  Directors  (the
"Board") of  MidAmerican  Energy  Holdings  Company,  an Iowa  corporation  (the
"Company"),  declared  a  dividend  of one  preferred  stock  purchase  right (a
"Right") for each  outstanding  share of Common Stock, no par value (the "Common
Stock"),  of the  Company.  The  dividend is payable on  December  30, 1996 (the
"Record  Date") to the  holders  of record of the  Common  Stock at the Close of
Business  on such  date.  Each Right  entitles  the  holder  thereof  (except as
described  below) to purchase from the Company one  one-hundredth  of a share of
the Series A Junior Participating  Preferred Stock, no par value (the "Preferred
Shares"),  of the  Company at a price (the  "Exercise  Price") of $50.00 per one
one-hundredth  of a Preferred  Share,  subject to  adjustment.  The terms of the
Rights are set forth in the  Shareholders  Rights Agreement dated as of December
18, 1996 (the  "Rights  Agreement")  between the Company and  Continental  Stock
Transfer & Trust  Company,  as Rights  Agent (the "Rights  Agent").  Capitalized
terms not defined  herein have the respective  meanings  specified in the Rights
Agreement.

                     Distribution Date; Transfer of Rights.

                           Initially,  the  Rights  associated  with the  Common
Stock  outstanding  as of the Record Date will be evidenced  solely by the stock
certificates  for such  Common  Stock,  with a copy of this  Summary  of  Rights
attached  thereto.  The Rights  will  separate  from the  Common  Stock upon the
earliest to occur of (i) 10 Business  Days after the first  public  announcement
that any Person  (other  than an Exempt  Person (as  hereinafter  defined))  has
become an Acquiring Person (as hereinafter  defined),  (ii) 10 Business Days (or
such other Business Day as may be determined by action of the Board prior to the
time that any Person  shall  become an  Acquiring  Person or  declared  to be an
Adverse Person (as  hereinafter  defined) after the  commencement  by any Person
(other  than an  Exempt  Person)  of, or the first  public  announcement  of its
intention  to  commence,  a tender or exchange  offer if, upon the  consummation
thereof,  such  Person  would  be the  Beneficial  Owner  of 15% or  more of the
outstanding  shares  of  Common  Stock  and  (iii)  10  Business  Days  after  a
determination by a majority of


                                       C-1

<PAGE>

the members of the Board of Directors of the Company who are not officers of the
Company that any Person has become an Adverse  Person (the earliest of the dates
specified  in  clauses  (i),  (ii)  and  (iii)  being  hereinafter   called  the
"Distribution  Date"). After the Distribution Date, the Rights will be evidenced
solely by separate  certificates  and will trade  independently  from the Common
Stock.

                           An  "Acquiring  Person"  is any  Person who or which,
together with its  Affiliates  and  Associates,  has acquired 15% or more of the
shares of Common Stock then  outstanding,  but does not include (i) the Company,
(ii) any  Subsidiary  of the Company,  (iii) any employee  benefit plan or other
compensation  program or arrangement of the Company or of any such Subsidiary or
(iv) any Person  holding  shares of Common Stock for or pursuant to the terms of
any such plan,  program or  arrangement  (the  Persons  specified in clauses (i)
through (iv) being herein  collectively  called "Exempt  Persons").  An "Adverse
Person" is any Person who or which, together with its Affiliates and Associates,
has acquired 10% or more of the shares of Common Stock then  outstanding and has
been determined, by at least a majority of the members of the Board of Directors
of the Company who are not  officers  of the  Company,  to be likely to act in a
manner  designed to produce a short-term  financial  gain for such Person to the
detriment of the best long-term interests of the Company and its shareholders. A
"Restricted  Person" is an Acquiring  Person, an Adverse Person or any Affiliate
or Associate thereof.

                           The  Rights   Agreement   provides  that,  until  the
Distribution Date (or the earlier  redemption or expiration of the Rights),  the
Rights may be transferred only with the associated shares of Common Stock. Until
the Distribution  Date (or the earlier  redemption or expiration of the Rights),
stock  certificates  for Common Stock issued after the Record Date,  either upon
transfer of  outstanding  shares or original  issuance of  additional  shares of
Common  Stock,  will  contain a legend  incorporating  the Rights  Agreement  by
reference.  Until the Distribution Date (or the earlier redemption or expiration
of the Rights),  the surrender for transfer of any stock  certificate for shares
of Common  Stock,  with or without such legend and whether or not a copy of this
Summary of Rights is attached thereto,  will also constitute the transfer of the
Rights  associated  with the shares of Common  Stock  represented  by such stock
certificate.

                           As soon as practicable  after the Distribution  Date,
separate  certificates  evidencing the Rights  ("Rights  Certificates")  will be
mailed to the holders of record of the Common  Stock as of the Close of Business
on the Distribution  Date, which thereafter will constitute the sole evidence of
the Rights. Each share of Common Stock issued by the Company after


                                       C-2

the Record Date and prior to the earlier redemption or expiration of the Rights,
including  any shares of Common  Stock  issued by reason of the  exercise of any
option,  warrant,  right  (other  than the  Rights) or  conversion  or  exchange
privilege  (however  evidenced)  issued by the Company prior to the Distribution
Date,  will be accompanied  by a Right (unless the Board  expressly pro vides to
the  contrary  at the time of  issuance of any such  option,  warrant,  right or
privilege), and Rights Certificates evidencing such Rights will be issued at the
same time as the stock certificates for the associated shares of Common Stock.

                           The Rights are not exercisable until the Distribution
Date.  Moreover,  the time when the Rights may be  exercised  is  restricted  as
described  in the next  paragraph.  The Rights will expire on December  30, 2006
(the "Final Expiration  Date"),  unless the Final Expiration Date is extended or
unless the Rights are earlier redeemed or exchanged by the Company, in each case
as described below.

                           Exercise of Rights Under Certain Circumstances.

                           In the event  that any Person  becomes  an  Acquiring
Person or is declared to be an Adverse Person,  proper provision will be made so
that the registered holder of each Right (other than Rights  Beneficially  Owned
as described in the next  sentence) will  thereafter  have the right to receive,
upon exercise  thereof,  the number of shares of Common Stock which, at the time
of the occurrence of such event, will have a market value equal to two times the
then current Exercise Price.  After the first occurrence of either of the events
described in the  preceding  sentence,  all Rights which are, or (under  certain
circumstances  specified in the Rights Agreement) were,  Beneficially Owned by a
Restricted  Person or specified  transferees  therefrom  will be or become void.
Under no  circumstances  may a Right be exercised after the occurrence of either
such event unless the Company's right to redeem the Rights (as described  below)
has expired.

                           If,  on or after  the date on which  any  Person  has
become an Acquiring Person or been declared to be an Adverse Person,  any of the
following  transactions  occur: (i) the Company merges into or consolidates with
an Interested Shareholder (as hereinafter defined) or, unless all holders of the
Company's  outstanding  shares of Common  Stock are  treated  the same,  another
Person (with limited designated exceptions);  (ii) an Interested Shareholder or,
unless  all  holders of the  Company's  outstanding  shares of Common  Stock are
treated the same,  another Person (with limited  designated  exceptions)  merges
into the Company and either (A) all or part of the outstanding  shares of Common
Stock of the Company are converted into capital stock or other securities of any
other Person (or the Company), cash and/or other property or


                                       C-3

<PAGE>

(B) such shares remain  outstanding,  unconverted  and  unchanged;  or (iii) the
Company  sells or transfers  50% or more of its  consolidated  assets or earning
power to an  Interested  Shareholder  (as  hereinafter  defined) or,  unless all
holders of the  Company's  outstanding  shares of Common  Stock are  treated the
same, another Person (with limited designated exceptions); proper provision will
be made so that the  registered  holder of each Right  (other than Rights  which
have become  void) will  thereafter  have the right (the  "Flip-Over  Right") to
receive,  upon exercise thereof, the number of common shares of the acquiror (or
of another Person  affiliated  therewith)  which, at the time of consummation of
such  transaction,  will have a market value equal to two times the then current
Exercise  Price.  An "Interested  Shareholder"  is any Restricted  Person or any
Affiliate or Associate of any other Person in which such  Restricted  Person has
an interest,  or any Person acting,  directly or indirectly,  on behalf of or in
concert with any such Restricted Person.

                           Adjustments to Exercise Price and Stock Purchasable
                           Upon Exercise.

                           The Exercise  Price  payable,  the number and kind of
shares of capital  stock  issuable upon exercise of the Rights and the number of
Rights  outstanding  are  subject  to  adjustment  from time to time to  prevent
dilution  (i) in the event of a dividend  payable in  Preferred  Shares on, or a
subdivision, combination or reclassification of, the Preferred Shares, (ii) upon
the grant to the holders of the Preferred Shares of certain options, warrants or
rights to subscribe for or purchase  Preferred  Shares at a price, or securities
convertible  into or  exchangeable  for  Preferred  Shares with a conversion  or
exchange price,  less than the then Fair Market Value of the Preferred Shares or
(iii) upon the  distribution  to the  holders of the  Preferred  Shares of cash,
securities,  evidences of  indebtedness  or other property (other than a regular
quarterly cash dividend or a dividend  payable in Preferred  Shares) or options,
warrants or rights (other than those referred to in clause (ii) above).

                           The  number of  outstanding  Rights and the number of
one one-hundredths of a Preferred Share issuable upon exercise of each Right are
also  subject  to  adjustment  in the event of a dividend  on the  Common  Stock
payable  in  shares  of  Common   Stock  or  a   subdivision,   combination   or
reclassification  of the Common Stock occurring,  in any such case, prior to the
Distribution Date.

                           With certain specified  exceptions,  no adjustment in
the Exercise Price will be made until the cumulative  adjustments required equal
at  least  1% of the  Exercise  Price.  The  Company  is not  required  to issue
fractional Preferred Shares (other than


                                       C-4

<PAGE>

fractions which are multiples of one one-hundredth of a Preferred Share), but in
lieu thereof the Company  would be required to make a cash payment  based on the
Fair  Market  Value of the  Preferred  Shares  on the  trading  day  immediately
preceding the date of exercise.

                           Terms of Preferred Shares.

                           The Preferred Shares  receivable upon exercise of the
Rights will not be  redeemable.  Each  Preferred  Share will  entitle the holder
thereof to receive a preferential quarterly dividend equal to the greater of (i)
$0.01 and (ii) 100 times the aggregate  per share amount of all cash  dividends,
plus 100 times the aggregate per share amount  (payable in kind) of all non-cash
dividends  and other  distributions  (other  than in  shares  of Common  Stock),
declared on the Common Stock during such quarter, adjusted to give effect to any
dividend  on  the  Common  Stock  payable  in  shares  of  Common  Stock  or any
subdivision,  combination or  reclassification  of the Common Stock (a "Dilution
Event").  Each  Preferred  Share will entitle the holder thereof to 100 votes on
all matters  submitted  to a vote of the  shareholders  of the  Company,  voting
together as a single  class with the holders of the Common Stock and the holders
of any other class of capital stock having general  voting  rights,  adjusted to
give effect to any Dilution  Event.  In the event of liquidation of the Company,
the holder of each  Preferred  Share will be entitled to receive a  preferential
liquidation  payment  equal to the  greater  of (i) $1.00 and (ii) 100 times the
aggregate per share amount to be distributed to the holders of the Common Stock,
adjusted to give effect to any Dilution  Event,  plus an amount equal to accrued
and unpaid dividends and  distributions on such Preferred Share,  whether or not
declared, to the date of such payment. In the event of any merger, consolidation
or other  transaction  in which the  outstanding  shares of Common  Stock of the
Company are exchanged for or converted  into other  capital  stock,  securities,
cash and/or other property,  each Preferred Share will be similarly exchanged or
converted  into 100 times the per share amount  applicable  to the Common Stock,
adjusted to give effect to any Dilution Event.

                  Because of the nature of the dividend, voting, liquidation and
other  rights  accorded  to  each  Preferred   Share,   the  value  of  the  one
one-hundredth  of a Preferred  Share  receivable upon the exercise of each Right
should approximate the value of one share of Common Stock.

                           Redemption of Rights.

                           At any time prior to the  earliest of (i) 10 Business
Days after the first public announcement that any Person (other


                                       C-5

<PAGE>

than an Exempt  Person) has become an Acquiring  Person,  (ii) 10 Business  Days
after any Person has been declared to be an Adverse Person, (iii) the occurrence
of any  transaction  which permits the exercise of the Flip-Over  Right and (iv)
the Final  Expiration Date, the Board may redeem the Rights in whole, but not in
part, at the redemption price of $.01 per Right,  adjusted to give effect to any
Dilution  Event (the  "Redemption  Price").  The redemption of the Rights may be
made  effective  at such  time,  on such basis and with such  conditions  as the
Board, in its sole discretion,  may establish.  Immediately  after action by the
Board directing the redemption of the Rights,  the option to exercise the Rights
will terminate, and thereafter each registered holder of the Rights will only be
entitled to receive the Redemption Price therefor.

                           Exchange of Rights.

                           At any time after any Person has become an  Acquiring
Person or been  declared to be an Adverse  Person and prior to the time that any
Person  (other  than  an  Exempt  Person),  together  with  its  Affiliates  and
Associates,  has become the Beneficial  Owner of 50% or more of the  outstanding
shares  of  Common  Stock,  the  Board  may  direct  that all or any part of the
outstanding  Rights  (other than Rights which have become void) be exchanged for
shares of Common Stock at the exchange rate of one share of Common Stock (or one
one-hundredth  of a Preferred  Share or of another share of capital stock of the
Company  having  equivalent  rights,  preferences  and  privileges)  per  Right,
adjusted to give effect to any Dilution Event.

                           Amendment of the Rights and the Rights Agreement.

                           Prior  to the  Distribution  Date,  the  terms of the
Rights and the Rights  Agreement may be  supplemented or amended by the Board in
any manner. From and after the Distribution Date, the Rights may be supplemented
or amended by the Board,  provided  however,  that such  supplement or amendment
shall not adversely affect the interests of the holders of the Rights.

                           Miscellaneous.

                           Until a Right is exercised,  the holder  thereof,  as
such,  will have no rights as a shareholder of the Company,  including,  without
limitation, the right to vote or to receive dividends.

                           A copy of the  Rights  Agreement  has been filed with
the  Securities  and  Exchange  Commission  as an  Exhibit  to a  Registra  tion
Statement on Form 8-A dated December 19, 1996. A copy of the Rights Agreement is
available free of charge from the

and is qualified in its entirety by reference to the Rights Agreement,  which is
hereby incorporated herein by reference.
