         (g)  The Company shall cause the Calculation Agent to calculate each
Interest Rate applicable to each Floating Rate Note in accordance with this
Indenture, and the Company shall, or shall cause the Calculation Agent to,
notify the Trustee of each determination of such Interest Rate promptly after

amount of the Global Notes.  The Company will provide to the Trustee not later
than the payment date sufficient moneys to pay in full all principal of and any
premium and Accrued Interest payments due on such payment date.  The Trustee
shall be responsible for withholding taxes on interest paid as required by law.

         (i)  Upon the request of any Noteholder of a Floating Rate Note, the
Trustee shall provide to such Noteholder the Interest Rate then in effect and,
if then determined, the Interest Rate that will become effective on the next

offices prior to the authentication and delivery of such Notes or did not hold

         (3)  an Opinion of Counsel stating,

              (A)  if the form of Notes has been established by or
         pursuant to a Board Resolution, an Officers' Certificate
         pursuant to a Board Resolution, or a supplemental indenture
         as permitted by Section 2.01, that such form has been
         established in conformity with this Indenture;

         enforceable in accordance with its terms, subject to
         bankruptcy, insolvency, reorganization and other laws of
         general applicability relating to or affecting the
         enforcement of creditors' rights and to general equity
         principles;

              (C)  that the Indenture, the Iowa-Illinois Indenture
         and the Midwest Power Indenture are qualified under the TIA;

              (D)  that any supplemental indenture referred to in (A)
         above has been duly authorized, executed and delivered by
         the Company and constitutes a legal, valid and binding
         agreement of the Company, enforceable in accordance with its
         terms, subject to bankruptcy, insolvency, reorganization and
         other laws of general applicability relating


                                         -34-



         to or affecting the enforcement of creditors' rights and to general
         equity principles;

              (E)  that the Notes, when authenticated and delivered
         by the Trustee and issued by the Company in the manner and
         subject to any conditions specified in such Opinion of
         Counsel consistent with the terms of this Indenture, will
         constitute legal, valid and legally binding obligations of
         the Company, enforceable in accordance with their respective
         terms, subject to bankruptcy, insolvency, reorganization and
         other laws of general applicability relating to or affecting
         the enforcement of creditors' rights and to general equity

         obligations under this Indenture, the Iowa-Illinois
         Indenture or the Midwest Power Indenture, and that the
         issuance of the Notes will not result in any such default;
         and

              (H)  such other matters as the Trustee may reasonably
         request.

         (d) The Trustee shall have the right to decline to authenticate and
deliver any Note:

         (1) if the issuance of such Note pursuant to this Indenture will
    affect the Trustee's own rights, duties or immunities under the Notes
    and this Indenture or otherwise in a manner which is not reasonably
    acceptable to the Trustee;

         (2)  if the Trustee, being advised by counsel, determines that
    such action may not lawfully be taken; or

         (3)  if the Trustee in good faith by its Board of Directors,
    executive committee or a trust committee of directors and/or
    responsible officers in good faith determines that such action would
    expose the Trustee to personal liability to Holders of any outstanding
    Notes.



                                         -35-



         (e)  No Note shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder and is entitled to the benefits of
this Indenture; PROVIDED, HOWEVER, that if any Note shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Note to the Trustee for cancellation as
provided in Section 2.09, for all purposes of this Indenture such Note shall be
deemed never to have been authenticated and delivered hereunder and shall never
be entitled to the benefits of this Indenture.

         (a)  Subject to Section 2.12, Notes may be exchanged for one or more
new Notes of any authorized denominations and of a like aggregate principal
amount and Stated Maturity and having the same terms and Original Issue Date or
Dates.  Notes to be exchanged shall be surrendered at any of the offices or
agencies to be maintained by the Company for such purpose as provided in Section
6.02, and the Company shall execute and register and the Trustee shall
authenticate and deliver in exchange therefor the Note or Notes which the
Noteholder making the exchange shall be entitled to receive.

         (b) The Trustee on behalf of the Company shall keep, at one of said
offices or agencies, a register in which, subject to such reasonable regulations
as it or the Company may prescribe, the Trustee shall register or cause to be
registered Notes and shall register or cause to be registered the transfer of
Notes as in this Article Two provided.  Such register shall be in written form
or in any other form capable of being converted into written form within a
reasonable time.   At all reasonable times such register shall be open for
inspection by the Trustee.  Upon due presentment for registration of transfer of
any Note at any such office or agency, the Company shall execute and register or
cause to be registered and the Trustee shall authenticate and make available for
delivery, in the name of the transferee or transferees, one or more new Notes of
any authorized denominations and of a like aggregate principal amount and Stated
Maturity and having the same terms and Original Issue Date or Dates.

         (c)  All Notes presented for registration of transfer or for
exchange, redemption or payment shall (if so required by the Company) be duly
endorsed by, or be accompanied by a written


                                         -36-



instrument or instruments of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder or the attorney of such Holder duly
authorized in writing.

         (d)  No service charge shall be made for any exchange or registration
of transfer of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.

         (e)  The Company shall not be required to exchange or register a
transfer of any Notes selected, called or being called for redemption except, in
the case of any Note to be redeemed in part, the portion thereof not to be so
redeemed.

         (f)  If the principal amount and any applicable premium of part but
not all of a Global Note is paid, then upon surrender to the Trustee of such
Global Note, the Company shall execute, and the Trustee shall authenticate, and
make available for delivery, a Global Note in an authorized denomination in
aggregate principal amount equal to, and having the same terms and Original
Issue Date or Dates as, the unpaid portion of such Global Note.

         SECTION 2.07.  MUTILATED, DESTROYED, LOST OR STOLEN NOTES.

         (a)  In case any temporary or definitive Note shall become mutilated
or be destroyed, lost or stolen, the Company in its discretion may execute, and
upon its request the Trustee shall authenticate and deliver, a new Note of like
form and principal amount and having the same terms and Original Issue Date or
Dates and bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the
Note so destroyed, lost or stolen.  In every case the applicant for a
substituted Note shall furnish to the Company, the Trustee, any Authenticating
Agent or Note registrar such security or indemnity as may be required by them to
save each of them harmless, and, in every case of destruction, loss or theft of
a Note, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof.

         (b)  The Trustee may authenticate any such substituted Note and
deliver the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substituted Note, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses connected therewith.
In case any Note which has matured or is


                                         -37-



about to mature shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substituted Note, pay or authorize the payment
of the same (without surrender thereof except in the case of a mutilated Note)
if the applicant for such payment shall furnish to the Company, the Trustee, any
Authenticating Agent or Note registrar such security or indemnity as may be
required by them to save each of them harmless and, in case of destruction, loss
or theft, evidence satisfactory to the Company and the Trustee of the
destruction, loss or theft of such Note and of the ownership thereof.

         (c)  Every substituted Note issued pursuant to this Section 2.07 by
virtue of the fact that any Note is destroyed, lost or stolen shall constitute
an additional contractual obligation of the Company, whether or not such
destroyed, lost or stolen Note shall be found at any time, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and
all other Notes duly issued hereunder.  All Notes shall be held and owned upon
the express condition that, to the extent permitted by law, the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Notes and shall preclude any and all other
rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

         SECTION 2.08.  TEMPORARY NOTES.  Pending the preparation of definitive
Notes, the Company may execute and the Trustee shall authenticate and make
available for delivery, temporary Notes (printed, lithographed or otherwise
reproduced).  Temporary Notes shall be issuable in any authorized denomination
and substantially in the form of the definitive Notes but with such omissions,
insertions and variations as may be appropriate for temporary Notes, all as may
be determined by the Company.  Every such temporary Note shall be authenticated
by the Trustee upon the same conditions and in substantially the same manner,
and with the same effect, as the definitive Notes.  Without unreasonable delay
the Company will execute and register and will deliver to the Trustee definitive
Notes and thereupon any or all temporary Notes may be surrendered in exchange
therefor, at the Corporate Trust Office of the Trustee, and the Trustee shall
authenticate and deliver in exchange for such temporary Notes an equal aggregate
principal amount of definitive Notes.  Such exchange shall be made by the
Company at its own expense and without any charge therefor to the Noteholders.
Until so exchanged, the temporary Notes shall in all respects be entitled  to
the same benefits under this Indenture as definitive Notes authenticated and
made available for delivery hereunder.


                                         -38-



         SECTION 2.09.  CANCELLATION OF NOTES PAID, ETC.  All Notes
surrendered for the purpose of payment, redemption, exchange or registration of
transfer shall be surrendered to the Trustee for cancellation and promptly
cancelled by it and no Notes shall be issued in lieu thereof except as expressly
permitted by this Indenture.  All Notes so cancelled shall be retained by the
Trustee.  If the Company shall acquire any of the Notes, however, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Notes unless and until the same are cancelled
by the Trustee.

         SECTION 2.10.  INTEREST RIGHTS PRESERVED.  Each Note delivered under
this Indenture upon transfer of or in exchange for or in lieu of any other Note
shall carry all the rights to unpaid Accrued Interest, and interest to accrue,
which were carried by such other Note, and each such Note shall be so dated that
neither gain nor loss of interest shall result from such transfer, exchange or
substitution.

         SECTION 2.11.  PAYMENT OF NOTES.  Unless otherwise specified in the
applicable Company Order, the principal of and any premium and Accrued Interest
on all Notes shall be payable in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts as follows:

         (a)  On or before 10:00 a.m., New York City time, of the day on which
any payment of principal, Accrued Interest or premium is due on any Global Note
pursuant to the terms thereof, the Company shall deliver to the Trustee
immediately available funds sufficient to make such payment.  On or before 10:30
a.m., New York City time or such other time as shall be agreed upon between the
Trustee and the Depositary, of the day on which such payment is due, the Trustee
shall deposit with the Depositary such funds by wire transfer into the account
specified by the Depositary.  As a condition to the payment at the Maturity of
any part of the principal and any applicable premium of any Global Note, the
Depositary shall surrender, or cause to be surrendered, such Global Note to the
Trustee, whereupon a new Global Note shall be issued to the Depositary pursuant
to Section 3.03(d).

         (b)  With respect to any Note that is not a Global Note, principal,
any premium and Accrued Interest due at the Maturity of such Note shall be
payable in immediately available funds when due upon presentation and surrender
of such Note at the Corporate Trust Office of the Trustee; PROVIDED that this
Note is presented to the Trustee in time for the Trustee to make such payment in
such funds in accordance with its normal procedures.  Accrued Interest on (and,
in the case of Amortizing



                                         -39-



Notes, installments of principal of) any Note that is not a Global Note (other
than Accrued Interest or such installments payable at Maturity) shall be paid by
a clearinghouse funds check mailed on the Interest Payment Date; PROVIDED,
HOWEVER, that if any Holder of Notes, the aggregate principal amount of which
equals or exceeds $10,000,000, provides a written request to the Trustee on or
before the applicable Record Date for such Interest Payment Date, Accrued
Interest (and such installments of principal) shall be paid by wire transfer of
immediately available funds to a bank within the continental United States or by
direct deposit into the account of such Holder if such account is maintained
with the Trustee.

         SECTION 2.12.  NOTES ISSUABLE IN THE FORM OF A GLOBAL NOTE.

         (a)  If the Company shall establish pursuant to Section 2.05 that
particular Notes are to be issued in whole or in part in the form of one or more
Global Notes, then the Company shall execute and the Trustee shall, in
accordance with Section 2.05 and the Company Order delivered to the Trustee
thereunder, authenticate and make available for delivery, such Global Note or
Notes, which (1) shall represent, shall be denominated in an amount equal to the
aggregate principal amount of, and shall have the same terms as, the outstanding
Notes to be represented by such Global Note or Notes, (2) shall be registered in
the name of the Depositary or its nominee, (3) shall be delivered by the Trustee
to the Depositary or pursuant to the Depositary's instruction and (4) shall bear
a legend substantially to the following effect:  "Unless and until it is
exchanged in whole or in part for the individual Notes represented hereby, this
Global Note may not be transferred except as a whole by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary."

         (b)  Notwithstanding any other provision of Section 2.06 or of this
Section 2.12, unless the terms of a Global Note expressly permit such Global
Note to be exchanged in whole or in part for individual Notes, a Global Note may
be transferred, in whole but not in part, only to a nominee of the Depositary,
or by a nominee of the Depositary to the Depositary, or to a successor
Depositary for such Global Note selected or approved by the Company or to a
nominee of such successor Depositary.

         (c)  (1) If at any time the Depositary for a Global Note notifies the
Company that such Depositary is unwilling or unable to continue as Depositary
for such Global Note or if at any time the Depositary for a Global Note shall no
longer be


                                         -40-



registered as a clearing agency under the Securities Exchange Act of 1934, as
amended, or any successor statute or regulation, the Company may appoint a
successor Depositary with respect to such Global Note.  If (A) a successor
Depositary for such Global Note is not appointed by the Company within 90 days
after the Company receives such notice or becomes aware of such ineligibility,
or (B) any Notes are represented by a Global Note at a time when an Event of
Default with respect to the Notes shall have occurred and be continuing, then in
each case the Company's election pursuant to the applicable Company Order shall
no longer be effective with respect to such Global Note and the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of individual Notes of like tenor and terms in exchange for such
Global Note, shall authenticate and make available for delivery, individual
Notes of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of such Global Note in exchange for such
Global Note.  The Trustee shall not be charged with knowledge of notice of the
ineligibility of a Depositary unless a responsible officer assigned to and
working in its corporate trust administration department shall have actual
knowledge thereof.

              (2)  The Company may at any time and in its sole discretion
determine that one or more Notes issued or issuable in the form of one or more
Global Notes shall no longer be represented by such Global Note or Notes.  In
such event the Company shall execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of individual Notes of like tenor and
terms in exchange for such Global Note or Notes, shall authenticate and make
available for delivery, individual Notes of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of such
Global Note or Notes in exchange for such Global Note or Notes.

              (3)  If agreed upon by the Company and the Depositary with
respect to Notes issued in the form of a Global Note, the Depositary for such
Global Note shall surrender such Global Note in exchange in whole or in part for
individual Notes of like tenor and terms in definitive form on such terms as are
acceptable to the Company and such Depositary.  Thereupon the Company shall
execute, and the Trustee shall authenticate and make available for delivery,
without a service charge, (A) to each Person specified by the Depositary, a new
Note or Notes of like tenor and terms, and of any authorized denomination as
requested by such Person, in aggregate principal amount equal to and in exchange
for the beneficial interest of such Person in such Global Note; and (B) to such
Depositary a new Global Note of like tenor and terms and in a denomination equal
to the difference, if any, between the principal amount of the


                                         -41-



surrendered Global Note and the aggregate principal amount of Notes delivered to
Holders thereof.

              (4)  In any exchange provided for in Section 2.12(c)(1),(2) or
(3), the Company will execute and the Trustee will authenticate and make
available for delivery, individual Notes in definitive registered form in
authorized denominations.  Upon the exchange of a Global Note for individual
Notes, such Global Note shall be cancelled by the Trustee.  Notes issued in
exchange for a Global Note pursuant to this Section 2.12 shall be registered in
such names and in such authorized denominations as the Depositary for such
Global Note, pursuant to instructions from its direct or indirect participants
or otherwise, shall instruct the Trustee.  The Trustee shall deliver such Notes
to the Depositary for delivery to the Persons in whose names such Notes are so
registered, or if the Depositary shall refuse or be unable to deliver such
Notes, the Trustee shall deliver such Notes to the Persons in whose names such
Notes are registered, unless otherwise agreed upon by the Trustee and the
Company.

         (d)  Neither the Company, the Trustee or any Authenticating Agent will
have any responsibility or liability for any aspect of the records relating to,
or payments made on account of, beneficial ownership interests in a Global Note
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

         (e)  Pursuant to the provisions of this subsection, at the option of
the Trustee and upon thirty days' written notice to the Depositary, the
Depositary shall be required to surrender any two or more Global Notes which
have identical terms, including, without limitation, identical maturities,
interest rates and redemption provisions (but which may have differing Original
Issue Dates) to the Trustee, and the Company shall execute and the Trustee shall
authenticate and deliver to, or at the direction of, the Depositary a Global
Note in principal amount equal to the aggregate principal amount of, and with
all terms identical to, the Global Notes so surrendered to the Trustee, and such
new Global Note shall indicate each applicable Original Issue Date and the
principal amount applicable to each such Original Issue Date.  The exchange
contemplated in this subsection shall be consummated at least 30 days prior to
any Interest Payment Date applicable to any of the Global Notes so surrendered
to the Trustee.  Upon any exchange of any Global Note with two or more Original
Issue Dates, whether pursuant to this Section or pursuant to Section 2.06 or
Section 3.03, the aggregate principal amount of the Notes with a particular
Original Issue Date shall be the same before and after such exchange, giving
effect to any retirement of Notes and the


                                         -42-



Original Issue Dates applicable to such Notes occurring in connection with such
exchange.

         SECTION 2.13.  CUSIP NUMBERS.  The Company in issuing Notes may use 
CUSIP numbers (if then generally in use), and, if so, the Trustee shall use 
CUSIP numbers in notices of redemption as a convenience to Noteholders; 
PROVIDED that any such notice may state that no representation is made as to 
the correctness of such CUSIP numbers either as printed on the Notes or as 
contained in any notice of redemption and that reliance may be placed only on 
the other identification numbers printed on the Notes, and any such 
redemption shall not be affected by any defect in or omission of such numbers.

                                    ARTICLE THREE

               REDEMPTION OF NOTES; REPAYMENT PRIOR TO STATED MATURITY

         SECTION 3.01.  APPLICABILITY OF REDEMPTION PROVISIONS. Unless
otherwise specified in the applicable Company Order, the Notes will not be
subject to any sinking fund.  If a Company Order specifies an Initial Redemption
Date for a Note, the Company shall have an option to redeem such Note prior to
its Stated Maturity on the date or dates and at the prices specified in such
Company Order, all as provided for in Sections 3.02 and 3.03, except as
otherwise specified in the applicable Company Order.

         SECTION 3.02.  NOTICE OF REDEMPTION; SELECTION OF NOTES.

         (a)  The election of the Company to redeem any Notes shall be
evidenced by a Board Resolution which shall be given with notice of such
redemption to the Trustee at least ten Business Days prior to the giving of the
notice of redemption to Holders of such Notes.  The selection of Notes or
portions thereof to be redeemed prior to their Stated Maturity shall be in the
sole discretion of the Company; PROVIDED that the Company shall give notice
thereof to the Trustee in accordance with Section 3.02(b).  Each Note which by
its terms is redeemable prior to its Stated Maturity may be redeemed by the
Company in whole or in part without also redeeming any other Note which is
redeemable prior to its Stated Maturity.

         (b)  Notice of redemption to each Holder of Notes to be redeemed as a
whole or in part shall be given by the Company (or, at the Company's request, by
the Trustee in the name and at the expense of the Company) in the manner
provided in Section 15.10 at least 30 but not more than 60 calendar days prior
to the



                                         -43-



Redemption Date.  Any notice which is given in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Noteholder
receives the notice.  In any case, failure duly to give such notice, or any
defect in such notice, to the Holder of any Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Note.

         (c)  Each such notice shall specify the Redemption Date, the places of
redemption and the redemption price at which such Notes are to be redeemed, and
shall state that payment of the redemption price of such Notes or portion
thereof to be redeemed will be made on surrender of such Notes at such places of
redemption, that Accrued Interest to the Redemption Date will be paid as
specified in such notice and that from and after such date interest thereon will
cease to accrue.  If less than all the Notes having the same terms are to be
redeemed, the notice shall specify the particular Notes or portions thereof to
be redeemed.  In case any Note is to be redeemed in part only, the notice which
relates to such Note shall state the portion of the principal amount thereof to
be redeemed, and shall state that, upon surrender of such Note, a new Note or
Notes having the same terms in aggregate principal amount equal to the
unredeemed portion thereof will be issued.

         (d)  If at the time of the mailing of any notice of redemption the
Company shall not have irrevocably directed the Trustee to apply funds deposited
with the Trustee or held by it and available to be used for the redemption of
Notes to redeem all the Notes called for redemption, such notice may state that
it is subject to the receipt of the redemption moneys by the Trustee before the
Redemption Date and that such notice shall be of no effect unless such moneys
are so received before such date.

         SECTION 3.03.  PAYMENT OF NOTES ON REDEMPTION; DEPOSIT  OF REDEMPTION
PRICE.

         (a)  If notice of redemption shall have been given as provided in
Section 3.02, such Notes or portions of Notes called for redemption shall become
due and payable on the date and at the places stated in such notice at the
applicable redemption price, together with Accrued Interest to the Redemption
Date of such Notes, and on and after the Redemption Date; PROVIDED that the
Company shall have deposited with the Trustee on or prior to the Redemption Date
funds in an amount sufficient to pay the redemption price together with Accrued
Interest to the Redemption Date of such Notes. Interest on the Notes or portions
thereof so called for redemption shall cease to accrue and such Notes or
portions thereof shall be deemed not to be entitled to any benefit under this
Indenture except to receive payment of the


                                         -44-



redemption price together with Accrued Interest to the Redemption Date of such
Notes; PROVIDED, HOWEVER, that any payments due with respect to such Note prior
to the Redemption Date shall be payable to the Holders of record of such Notes
at the close of business on the relevant Record Date specified in the applicable
Company Order.  On presentation and surrender of such Notes at such a place of
payment in such notice specified, such Notes or the specified portions thereof
shall be paid and redeemed at the applicable Redemption Price.

         (b)  The Company shall not mail any notice of redemption of Notes
during the continuance of any Event of Default, except that (1) where notice of
redemption of any Notes has theretofore been mailed, the Company shall redeem
such Notes; PROVIDED that funds have theretofore been deposited for such
purpose, and (2) notices of redemption of all outstanding Notes may be given
during the continuance of an Event of Default.

         (c)  If any Note called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and any premium  on such
Note, shall until paid bear interest from the date fixed for redemption at the
rate borne by such Note.

         (d)  Upon surrender of any Note redeemed in part only, the Company
shall execute and register, and the Trustee shall authenticate and make
available for delivery, a new Note or Notes of authorized denominations in
aggregate principal amount equal to, and having the same terms and Original
Issue Date or Dates as, the unredeemed portion of the Note so surrendered.

         SECTION 3.04.  REPAYMENT AT THE OPTION OF THE HOLDER.

         (a) Unless otherwise specified in the applicable Company Order, Notes
shall not be repayable prior to Stated Maturity at the option of the Holder.  If
so specified, a Note shall be repayable at the option of the Holder, in whole or
in part, on a date or dates prior to Stated Maturity and at a price or prices
specified in the applicable Company Order, plus accrued and unpaid interest to
but excluding the date of repayment.

         (b)  In order for a Note that is repayable at the option of the Holder
to be repaid prior to Stated Maturity, such Holder shall deliver or cause to be
delivered to the Trustee at least 30 but not more than 45 calendar days prior to
the repayment date: (i) the Note with the form entitled "Option to Elect
Repayment" on the reverse of the Note duly completed, or (ii) a telegram, telex,
facsimile transmission, hand delivery or letter (first class, postage prepaid)
from a member of a national securities exchange or the National Association of
Securities Dealers, Inc. or a commercial bank or trust company in the United


                                         -45-



States setting forth the name of the Holder of the Note, the principal amount of
the Note, the principal amount of the Note to be repaid, the certificate number
or a description of the tenor and terms of the Note, a statement that the option
to elect repayment is being exercised thereby and a guarantee that the Note to
be repaid with the form entitled "Option to Elect Repayment" on the reverse of
the Note duly completed shall be received by the Trustee not later than five
Business Days after the date of such telegram, telex, facsimile transmission,
hand delivery or letter, if such Note and form duly completed are received by
the Trustee by such fifth Business Day.

         (c)  Exercise of the repayment option by the Holder of a Note shall be
irrevocable, except that a Holder who has tendered a Note for repayment may
revoke such tender for repayment by written notice to the Trustee received prior
to 5:00 P.M., New York City time, on the tenth calendar day prior to the
repayment date.

         (d)  Unless otherwise specified in the applicable Company Order, the
repayment option may be exercised by the Holder of a Note for less than the
entire principal amount of the Note; PROVIDED that the principal amount of the
Note remaining outstanding after such repayment is an authorized denomination.
Upon such partial repayment such Note will be cancelled and a new Note or Notes
for the remaining principal amount thereof shall be issued in the name of the
Holder thereof.

         (e)  While any Note is represented by one or more Global Notes, any
such option for repayment may be exercised by the applicable participant in the
Depositary that has an account for Notes with the Depositary, on behalf of the
beneficial owners of the Note represented by such Global Note or Notes, by
delivering a written notice substantially similar to the above-mentioned form
duly completed to the Trustee at its Corporate Trust Office (or such other
address of which the Company shall from time to time notify the Holders), at
least 30 but not more than 60 calendar days prior to the date of repayment.
Notices of election from such participants on behalf of beneficial owners of the
Global Note or Notes representing such Notes to exercise their option to have
such Notes repaid shall be received by the Trustee by 5:00 P.M., New York City
time, on the last day for giving such notice.  All notices shall be executed by
a duly authorized officer of such participant (with signatures guaranteed) and
shall be irrevocable. In addition, beneficial owners of the Global Note or Notes
representing Notes shall effect delivery to the Depositary at the time such
notices of election are given by causing the applicable participant to transfer
such beneficial owner's interest in the Global Note or


                                         -46-



Notes representing such Notes, on the Depositary's records, to the Trustee.

         SECTION 3.05.  EXTENSION.

         (a) If a Company Order specifies an Extension Period or Periods for a
Note, the Company shall have an option to extend the Stated Maturity of such
Note for one or more Extension Periods specified in such Company Order, but not
beyond the Final Maturity Date specified therein.  The Company may exercise such
option by notifying the Trustee of such exercise at least 45 but not more than
60 calendar days prior to the Pre-Exercise Stated Maturity Date of such Note,
and after receipt of such notification, the Trustee shall send not later than 40
calendar days prior to such Pre-Exercise Stated Maturity Date an Extension
Notice to the Holder of such Note.

         (b)  Upon the sending by the Trustee of an Extension Notice to the
Holder of a Note, the Stated Maturity of such Note will be extended
automatically, and, except as modified by the Extension Notice and, subject to
Section 3.05(c) and (d), such Note will have the same terms as prior to the
sending of such Extension Notice.

         (c)  Notwithstanding Sections 3.05(a) and (b), not later than 20
calendar days prior to the Pre-Exercise Stated Maturity Date, the Company may,
at its option, revoke the interest rate, in the case of a Fixed Rate Note, or
the Spread and/or Spread Multiplier, in the case of a Floating Rate Note,
provided for in the Extension Notice and establish a higher interest rate, in
the case of a Fixed Rate Note, or a Spread and/or Spread Multiplier resulting in
a higher interest rate, in the case of a Floating Rate Note, for the Extension
Period by causing the Trustee to send by telegram, telex, facsimile
transmission, hand delivery or letter (first class, postage prepaid) notice of
such higher interest rate or Spread and/or Spread Multiplier resulting in a
higher interest rate, as the case may be, to the Holder of such Note, and such
notice will be irrevocable.  All Notes with respect to which the Stated Maturity
is extended will bear such higher interest rate, in the case of a Fixed Rate
Note, or Spread and/or Spread Multiplier resulting in a higher interest rate, in
the case of a Floating Rate Note, for the Extension Period, whether or not
tendered for repayment as provided in Section 3.05(d).

         (d)  If the Company extends the Stated Maturity of a Note (including,
if such Stated Maturity has previously been extended, the Stated Maturity as
previously extended), the Holder of such Note shall have the option to elect
repayment of such Note, in whole but not in part, by the Company on the Pre-



                                         -47-



Exercise Stated Maturity Date (including, if such Stated Maturity has previously
been extended, the last day of the then current Extension Period), at a price
equal to the principal amount thereof plus accrued and unpaid interest to but
excluding such date.  In order for a Note to be so repaid on the Pre-Exercise
Stated Maturity Date, the Holder thereof must follow the procedures set forth in
Section 3.04 for optional repayment, except that the period for delivery of such
Note or notification to the Trustee will be at least 25 but not more than 35
calendar days prior to the Pre-Exercise Stated Maturity Date.  A Holder who has
tendered a Note for repayment following receipt of an Extension Notice may
revoke such tender for repayment by written notice to the Trustee received prior
to 5:00 P.M., New York City time, on the tenth calendar day prior to the
Pre-Exercise Stated Maturity Date.

         SECTION 3.06.  RESET NOTES.

         (a) If a Company Order specifies Optional Interest Reset Dates for a
Note, the Company shall have an option to reset the interest rate of a Fixed
Rate Note or the Spread and/or Spread Multiplier of a Floating Rate Note,
subject to any formula for such resetting specified in such Company Order.  The
Company may exercise such option by notifying the Trustee of such exercise at
least 45 but not more than 60 calendar days prior to an Optional Interest Reset
Date for such Note.  If the Company so notifies the Trustee of such exercise,
the Trustee shall send not later than 40 calendar days prior to such Optional
Interest Reset Date, by telegram, telex, facsimile transmission, hand delivery
or letter (first class, postage prepaid) to the Holder of such Note, a Reset
Notice, including the date or dates on which or the period or periods during
which and the price or prices at which redemption of such Note may occur during
the Subsequent Interest Period commencing on such Optional Interest Reset Date.

         (b)  Notwithstanding Section 3.06(a), not later than 20 calendar days
prior to an Optional Interest Reset Date for a Note, the Company may, at its
option, revoke the interest rate, in the case of a Fixed Rate Note, or the
Spread and/or Spread Multiplier, in the case of a Floating Rate Note, provided
for in a Reset Notice and establish a higher interest rate, in the case of a
Fixed Rate Note, or a Spread and/or Spread Multiplier resulting in a higher
interest rate, in the case of a Floating Rate Note, for the Subsequent Interest
Period commencing on such Optional Interest Reset Date by causing the Trustee to
send by telegram, telex, facsimile transmission, hand delivery or letter (first
class, postage prepaid) notice of such higher interest rate or Spread and/or
Spread Multiplier resulting in a higher interest rate, as the case may be, to
the Holder of such Note, and such notice will be irrevocable.  All Notes with
respect to


                                         -48-



which the interest rate or Spread and/or Spread Multiplier is reset on an
Optional Interest Reset Date to a higher interest rate or Spread and/or Spread
Multiplier resulting in a higher interest rate will bear such higher interest
rate, in the case of a Fixed Rate Note, or Spread and/or Spread Multiplier
resulting in a higher interest rate, in the case of a Floating Rate Note,
whether or not tendered for repayment as provided in Section 3.06(c).

         (c)  If the Company elects prior to an Optional Interest Reset Date to
reset the interest rate or the Spread and/or Spread Multiplier of a Note, the
Holder of such Note shall have the option to elect repayment of such Note, in
whole but not in part, by the Company on such Optional Interest Reset Date at a
price equal to the principal amount thereof plus accrued and unpaid interest to
but excluding such Optional Interest Reset Date.  In order for a Note to be so
repaid on an Optional Interest Reset Date, the Holder thereof must follow the
procedures set forth in Section 3.04, except that the period for delivery of
such Note or notification to the Trustee will be at least 25 but not more than
35 calendar days prior to such Optional Interest Reset Date.  A Holder who has
tendered a Note for repayment following receipt of a Reset Notice may revoke
such tender for repayment by written notice to the Trustee received prior to
5:00 P.M., New York City time, on the tenth calendar day prior to such Optional
Interest Reset Date.

                    SATISFACTION AND DISCHARGE; UNCLAIMED MONEYS

         SECTION 5.01.  SATISFACTION AND DISCHARGE.  This Indenture shall, upon
the request of the Company set forth in an Officers Certificate, cease to be of
further effect and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture,
when

         (1)  either

         (A)  all Notes theretofore authenticated and delivered (other than (i)
    Notes which have been destroyed, lost or stolen and which have been
    replaced or paid as provided in Section 2.07, (ii) Notes for which payment
    money has theretofore been deposited with or paid to the Trustee and
    thereafter repaid to the Company or discharged from such trust, as provided
    in Section 5.03) have been delivered to the Trustee for cancellation; or

         (B)  all such Notes not theretofore delivered to the Trustee for
    cancellation,

              (i)  have become due and payable, or

             (ii)  will become due and payable at their Stated Maturity within
                   one year, or

            (iii)  are to be called for redemption within one year under
                   arrangements satisfactory to the Trustee for the giving of
                   notice by the Trustee in the name, and at the expense, of
                   the Company,

    and the Company, in the case of (i), (ii) or (iii) of this subclause (B),
    has irrevocably deposited or caused to be deposited with the Trustee as
    trust funds in trust for such purpose an amount in United States dollars,
    U.S. Government Obligations maturing as to principal and interest in such
    amounts and at such times as will ensure the availability of United States
    dollars, or a combination of United States dollars and U.S. Government
    Obligations, sufficient to pay and discharge the entire indebtedness on
    such Notes for principal (and premium, if any) and interest to the date of
    such deposit (in the case of Notes which have become due and payable) or to
    the Stated Maturity or Redemption Date, as


                                         -52-



    the case may be; PROVIDED, HOWEVER, in the event a petition for relief
    under the federal bankruptcy laws, as now or hereafter constituted, or any
    other applicable federal or state bankruptcy, insolvency or other similar
    law, is filed with respect to the Company within 91 days after the deposit
    and the Trustee is required to return the deposited money to the Company,
    the obligations of the Company under this Indenture with respect to such
    Notes shall not be deemed terminated or discharged;

         (2)  the Company has paid or caused to be paid all other sums payable
    hereunder by the Company;

         (3)  the Company has delivered to the Trustee an Officers' Certificate
    and an Opinion of Counsel each stating that all conditions precedent herein
    provided for relating to the satisfaction and discharge of this Indenture
    with respect to such Notes have been complied with; and

         (4)  the Company has delivered to the Trustee an Opinion of Counsel or
    a ruling by the Internal Revenue Service to the effect that Holders of the
    Notes will not recognize income, gain or loss for federal income tax
    purposes as a result of such deposit and discharge.

Notwithstanding the satisfaction and discharge of this Indenture,
this Indenture shall continue in effect as to (i) rights of registration of
transfer and exchange of Notes, (ii) substitution of apparently mutilated,
defaced, destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive
payments of principal thereof and any premium and interest thereon, upon the
original stated due dates therefor (but not upon acceleration of maturity), (iv)
the rights, obligations and immunities of the Trustee hereunder and (v) the
rights of the Holders of Notes as beneficiaries hereof with respect to the
property so deposited with the Trustee payable to all or any of them), and the
Trustee, on demand of the Company accompanied by an Officers' Certificate and an
Opinion of Counsel and at the cost and expense of the Company, shall execute
proper instruments acknowledging such satisfaction of and discharging this
Indenture.  Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 9.07 shall survive.

         SECTION 5.02.  DEPOSITED MONEYS TO BE HELD IN TRUST BY TRUSTEE.
Subject to Section 5.03, all moneys and U.S. Government Obligations deposited
with the Trustee pursuant to Section 5.01 shall be held in trust and applied by
it to the payment, either directly or through any paying agent (including the
Company if acting as its own paying agent), to the Holders of the particular
Notes for the payment or redemption of which such moneys and U.S.


                                         -53-



Government Obligations have been deposited with the Trustee, of all sums due and
to become due thereon for principal and premium, if any, and interest.

         SECTION 5.03.  RETURN OF UNCLAIMED MONEYS.  Any moneys deposited with
or paid to the Trustee for payment of the principal of or any premium or
interest on any Notes and not applied but remaining unclaimed by the Holders of
such Notes for two years after the date upon which the principal of or any
premium or interest on such Notes, as the case may be, shall have become due and
payable, shall be repaid to the Company by the Trustee on written demand and all
liability of the Trustee shall thereupon cease; and any Holder of any of such
Notes shall thereafter look only to the Company for any payment which such
Holder may be entitled to collect; PROVIDED, HOWEVER, that the Trustee before
being required to make any such repayment, may at the expense of the Company
cause to be mailed to such Holder notice that such money remains unclaimed and
that, after a date specified therein which shall not be less than 30 days from
the date of such mailing, any unclaimed balance of such money then remaining
will be repaid to the Company.

         SECTION 5.04.  REINSTATEMENT.  If the Trustee is unable to apply any
money or U.S. Government Obligations in accordance with Section 5.01 by reason
of any legal proceeding or any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture with respect to the Notes to which
such money or U.S. Government Obligations were to have been applied shall be
revived and reinstated as though no deposit had occurred pursuant to Section
5.01 until such time as the Trustee is permitted to apply such money or U.S.
Government Obligations in accordance with Section 5.01; PROVIDED, HOWEVER, that
if the Company has made any payment of principal of or any premium or interest
on any Notes because of the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Notes to receive such payment
from the money or U.S. Government Obligations held by the Trustee.


                                     ARTICLE SIX

provided, and where, at any time when the Company is obligated to make a payment
upon Notes (other than a payment as to which it is permitted to make such
payment by check), the Notes may be presented for payment, and shall maintain at
any such office or agency and at its principal office an office or agency where
notices and demands to or upon the Company in respect of the Notes or of this
Indenture may be served; PROVIDED that the Company may maintain at its principal
executive offices, one or more other offices or agencies for any or all of the
foregoing purposes; the Company hereby appoints the Trustee as agent of the
Company for the foregoing purposes.  The Company will give to the Trustee
written notice of the location of each such office or agency and of any change
of location thereof.  In case the Company shall fail to maintain any such office
or agency or shall fail to give such notice of the location or of any change in
the location thereof, presentations may be made and notices and demands may be
served at the Corporate Trust Office of the Trustee.

         SECTION 6.03.  APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE.

Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence, rights (charter and statutory)

preservation thereof is no longer desirable in the conduct of the business of
the Company.

         SECTION 6.06.  LIMITATION UPON MORTGAGES AND LIENS.  The Company will
not at any time directly or indirectly create or assume and will not cause or

or encumbrance upon any Principal Facility or any interest it may have therein
or upon any stock of any Subsidiary or any indebtedness of any Subsidiary to the
Company or any other Subsidiary, whether now owned or hereafter acquired,
without making effective provision (and the Company covenants that in such case
it will make or cause to be made, effective provision) whereby the outstanding
Notes and any other indebtedness of the Company then entitled thereto shall be
secured by such mortgage, pledge, lien or encumbrance equally and ratably with
any and all other obligations and indebtedness thereby secured, so long as any
such other obligations and indebtedness shall be so secured (provided, that for
the purpose of providing such equal and ratable security, the principal amount
of outstanding Original Issue Discount Notes shall be their Amortized Face
Amount); PROVIDED, HOWEVER, that the foregoing covenant shall not be applicable
to the lien of the Iowa-Illinois Indenture, the lien of the Midwest Power
Indenture or Permitted Encumbrances.

         SECTION 6.07.  WAIVER OF CERTAIN COVENANTS.  The Company may omit in
any particular instance to comply with any term, provision or condition set
forth in Article Four or Section 6.06 (and if so specified, any other covenant
not set forth herein and specified pursuant to Section 2.05 to be applicable to
any Notes, except as otherwise provided pursuant to Section 2.05), if before the
time for such compliance the Holders of at least a majority in aggregate
principal amount of the Notes then outstanding shall either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no waiver shall extend to or affect such term,
provision or condition except to the extent expressly so waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such


                                         -56-



term, provision or condition shall remain in full force and effect.

    for a period of 60 days after there has been given, by registered or
    certified mail, to the Company by the Trustee or to the Company and the
    Trustee by the Holders of at least 25% in principal amount of the Notes
    then outstanding, a written notice specifying such default or breach and

    $10,000,000 principal amount that results in such Indebtedness becoming or
    being declared due and payable prior to the date on which it would
    otherwise become due and payable, and such acceleration shall not have been
    rescinded or annulled, or such Indebtedness shall not have been discharged,
    within a period of 15 days after there has been given, by registered or
    certified mail, to the Company by the Trustee or to the Company and the

    money, either individually or in the aggregate, in excess of $10,000,000,
    and the continuance of such judgment, decree or other unsatisfied and in
    effect for any period of 45 consecutive


                                         -58-



    days after the amount thereof is due without a stay of execution and there
    has been given, by registered or certified mail, to the Company by the
    Trustee or to the Company and the Trustee by the Holders of at least 25% in
    principal amount of the Notes then outstanding, a written notice specifying
    such entry and continuance of such judgment, decree or order and stating
    that such notice is a "Notice of Default" hereunder; or

         (6)  the entry of a decree or order for relief in respect of the

    case under the federal bankruptcy laws, as now or hereafter constituted, or
    any other applicable federal or state bankruptcy, insolvency or other
    similar law, or a decree or order adjudging the Company a bankrupt or
    insolvent, or approving as properly filed a petition seeking
    reorganization, arrangement, adjustment or composition of or in respect of
    the Company under any applicable federal or state law, or appointing a
    receiver, liquidator, assignee, custodian, trustee, sequestrator (or other
    similar official) of the Company or of any substantial part of its

    case under any such law or to the appointment of a receiver, liquidator,
    assignee, custodian, trustee, sequestrator (or other similar official) of
    the Company or of any substantial part of its property, or the making by it
    of an assignment for the benefit of its creditors, or the admission by it
    in writing of its inability to pay its debts generally as they become due,
    or the taking of corporate action by the Company in furtherance of any such
    action; or

         (8)  any other Event of Default provided with respect to the
    particular Note specified in the applicable Company Order.

         SECTION 8.02.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.  If
an Event of Default with respect to the Notes then outstanding occurs and is
continuing, then in every such case the Trustee or the Holders of not less than
25% in principal amount of the Notes then outstanding may declare the principal
amount of all the Notes to be due and payable immediately, by a notice in


                                         -59-



writing in the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount shall become immediately due and payable.
Upon payment of such amount in United States dollars, all obligations of the
Company in respect of the payment of principal of the Notes shall terminate.


         At the time after such a declaration of acceleration with respect to
the Notes has been made and before a judgment or decree for payment of the money
due has been obtained by the Trustee as hereinafter in this Article provided,
the Holders of a majority in aggregate principal amount of the Notes then
outstanding, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if

         (1)  the Company has paid or deposited with the Trustee a sum in
    United States dollars sufficient to pay

         (A)  all overdue installments of interest on all Notes,

         (B)  the principal of (and premium, if any, on) any Notes which have
              become due otherwise than by such declaration of acceleration and
              interest thereon at the rate or rates prescribed therefor in such
              Notes,

         (C)  to the extent that payment of such interest is lawful, interest
              upon overdue installments of interest on each Note at the rate
              borne by such Note, and

         (D)  all sums paid or advanced by the Trustee hereunder and the
              reasonable compensation, expenses, disbursements and advances of
              the Trustee, its agents and counsel;

    and

         (2)  All Events of Default with respect to the Notes, other than the
    nonpayment of the principal of Notes which has become due solely by such
    declaration of acceleration, have been cured or waived as provided in
    Section 8.11.

No such rescission and waiver shall affect any subsequent default or impair any
right consequent thereon.

         SECTION 8.03.  COLLECTION AND SUITS FOR ENFORCEMENT BY TRUSTEE.  The
Company covenants that if

         (1)  default is made in the payment of any installment of interest on
    any Note when such interest becomes due and


                                         -60-



    payable and such default continues for a period of 30 days, or

         (2)  default is made in the payment of principal of (or premium, if
    any, on) any Notes as and when the name shall have become due and payable,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the amount then due and payable on such Notes, for the
principal (and premium, if any) and interest, if any, and, to the extent that
payment of such interest shall be legally enforceable, interest upon the overdue
principal (and premium, if any) and upon overdue installments of interest, at
the rate borne by the Notes; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         If the Company fails to pay such amount forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor under such Notes, and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Notes wherever
situated.

         If an Event of Default with respect to any Notes occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of the Notes by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

         SECTION 8.04.  TRUSTEE MAY FILE PROOFS OF CLAIM.  In the case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceedings, or any voluntary or involuntary case under the federal bankruptcy
laws, as now or hereafter constituted, relative to the Company or any other
obligor upon the Notes or the property of the Company or of such other obligor
or their creditors, the Trustee (irrespective of whether the principal of such
Notes shall then be due and payable as therein expressed or by declaration of
acceleration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal or


                                         -61-



interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (i)  to file and prove a claim for the whole amount of principal (or,
    if any Notes are Original Issue Discount Securities, the Amortized Face
    Amount thereof or such other portion of the principal amount as may be due
    and payable with respect to such Original Issue Discount Notes pursuant to
    a declaration in accordance with Section 8.02) (and premium, if any) and
    interest owning and unpaid in respect of the Notes and to file such other
    papers or documents as may be necessary or advisable in order to have the
    claims of the Trustee (including any claim for the reasonable compensation,
    expenses, disbursements and advances of the Trustee, its agents and
    counsel) and of the Holders of such Notes allowed in such judicial
    proceeding, and

         (ii) to collect and receive any moneys or other property payable or
    deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, custodian, liquidator, sequestrator (or
other similar official) in any such proceeding is hereby authorized by each such
Holder to make such payments to the Trustee, and in the event that the Trustee
shall consent to the making of such payments directly to such Holders, to pay to
the Trustee and amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.06.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

         SECTION 8.05.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF NOTES.
All rights of action and claims under this Indenture or the Notes may be
prosecuted and enforced by the Trustee without the possession of any of such
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name, as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes in respect of which such judgment has been recovered.


                                         -62-



         SECTION 8.06.  APPLICATION OF MONEYS COLLECTED BY TRUSTEE.  Any moneys
collected by the Trustee with respect to any of the Notes shall be applied in
the order following, at the date or dates fixed by the Trustee for the
distribution of such moneys, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof
if fully paid:

         FIRST:  To the payment of all amounts due to the Trustee pursuant
    to Section 9.07;

         SECOND:  In case the principal of the Notes then outstanding in
    respect of which such moneys have been collected shall not have become
    due and be unpaid, to the payment of interest on the Notes, in the
    order of the maturity of the installments of such interest, with
    interest (to the extent allowed by law and to the extent that such
    interest has been collected by the Trustee) upon the overdue
    installments of interest at the rate borne by the Notes, such payments
    to be made ratably to the persons entitled thereto;

         THIRD:  In case the principal of the Notes then outstanding in
    respect of which such moneys have been collected shall have become
    due, by declaration or otherwise, to the payment of the whole amount
    then owing and unpaid upon the Notes for principal and any premium and
    interest thereon, with interest on the overdue principal and any
    premium and (to the extent allowed by law and to the extent that such
    interest has been collected by the Trustee) upon overdue installments
    of interest at the rate borne by the Notes; and in case such moneys
    shall be insufficient to pay in full the whole amount so due and
    unpaid upon the Notes, then to the payment of such principal and any
    premium and interest without preference or priority of principal and
    any premium over interest, or of interest over principal and any
    premium or of any installment of interest over any other installment
    of interest, or of any Note over any other Note, ratably to the
    aggregate of such principal and any premium and accrued and unpaid
    interest; and

         FOURTH:  To the payment of the remainder, if any, to the Company
    its successors or assigns, or to whomsoever may lawfully be entitled
    to the same, or as a court of competent jurisdiction may determine.


                                         -63-



         SECTION 8.07.  PROCEEDINGS BY NOTEHOLDERS.

         (a)  No Holder of any Note shall have any right by virtue of or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written
notice of default with respect to such Note and of the continuance thereof, as
hereinabove provided, and unless also the Holders of not less than a majority in
aggregate principal amount of the Notes then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding, it being understood and intended,
and being expressly covenanted by the taker and the Holder of every Note with
every other taker and Holder and the Trustee that no one or more Holders of
Notes shall have any right in any manner whatever by virtue of or by availing of
any provision of this Indenture to affect, disturb or prejudice the rights of
any other Holder of Notes, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all Holders of Notes.

         (b)  Notwithstanding any other provision in this Indenture, however,
the rights of any Holder of any Note to receive payment of the principal of and
any premium and interest on such Note, on or after the respective due dates
expressed in such Note (or, in the case of redemption, on the Redemption Date),
or to institute suit for the enforcement of any such payment on or after such
respective dates shall not be impaired or affected without the consent of such
Holder.

         SECTION 8.08.  PROCEEDINGS BY TRUSTEE.  In case of an Event of Default
hereunder the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any of such
rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.


                                         -64-



         SECTION 8.09.  REMEDIES CUMULATIVE AND CONTINUING.  All powers and
remedies given by this Article Eight to the Trustee or to the Noteholders shall,
to the extent permitted by law, be deemed cumulative and not exclusive of any
powers and remedies hereof or of any other powers and remedies available to the
Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to
enforce the performance or observance of the covenants and agreements contained
in this Indenture, and no delay or omission of the Trustee or of any Holder of
any of the Notes in exercising any right or power accruing upon any default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to Section 8.07, every power and remedy given by this
Article Eight or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or
by the Noteholders.

         SECTION 8.10.  RESTORATION OF RIGHTS AND REMEDIES.  If the Trustee or
any Noteholder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such
Noteholder, then and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Noteholders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Company, the Trustee and the Noteholders shall
continue as though no such proceeding had been instituted.

         SECTION 8.11.  DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY NOTEHOLDERS.  The Holders of a majority in aggregate principal amount
of the Notes then outstanding shall have the right to direct the time, method,
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee; PROVIDED, HOWEVER,
that (subject to Section 9.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee being advised by counsel determines
that the action or proceeding so directed may not lawfully be taken or if the
Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees or responsible officers
shall determine that the action or proceeding so directed would involve the
Trustee in personal liability or would be unduly prejudicial to the rights of
Noteholders not joining in such directions.  Prior to any declaration
accelerating the Maturity of the Notes, the Holders of a majority in aggregate
principal amount of the Notes then outstanding may on behalf of all of the
Holders of all of the Notes waive any past default or Event of Default hereunder
and


                                         -65-



its consequences, except a default (i) in the payment of principal of or any
premium or interest on any Note or (ii) in respect of a covenant or provision
hereof which pursuant to Section 13.02 cannot be modified or amended without the
consent of the Holder of each Note then outstanding that would be affected
thereby.  Upon any such waiver, such default will cease to exist, and any Event
of Default arising therefrom will be deemed to have been cured, for every
purpose of the Indenture and the Notes, but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.

         SECTION 8.12.  NOTICE OF DEFAULT.  The Trustee shall, within 90 days
after the occurrence of a default with respect to the Notes, give to all Holders
of the Notes specified in TIA Section 3.13(c), in the manner provided in Section
15.10, notice of such default, unless such default shall have been cured before
the giving of such notice, the term "default" for the purpose of this Section
8.12 being hereby defined to be any event which is or after notice or lapse of
time or both would become an Event of Default; PROVIDED that, except in the case
of default in the payment of the principal of or any premium or interest on any
of the Notes, the Trustee shall be protected in withholding such notice if and
so long as its board of directors or trustees, executive committee, or a trust
committee of directors or trustees or responsible officers in good faith
determines that the withholding of such notice is in the interests of the
Holders of the Notes.  The Trustee shall not be charged with knowledge of any
Event of Default unless a responsible officer of the Trustee assigned to the
corporate trust division of the Trustee shall have actual knowledge of such
Event of Default.

         SECTION 8.13.  UNDERTAKING TO PAY COSTS.  All parties to this
Indenture agree, and each Holder of any Note by acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but this Section 8.13 shall not apply to any suit
instituted by the Trustee, or to any suit instituted by any Noteholder, or group
of Noteholders, holding in the aggregate more than 10% in principal amount of
the Notes then outstanding, or to any suit instituted by any Noteholder for the
enforcement of the payment of the principal of or any premium or interest on any
Note on or after the due date expressed in such Note.


                                         -66-



                                     ARTICLE NINE

                                CONCERNING THE TRUSTEE

         SECTION 9.01.  CERTAIN DUTIES AND RESPONSIBILITIES.

    (a)  Except during the continuance of an Event of Default,

         (1)  the Trustee undertakes to perform such duties and only such
    duties as are specifically set forth in this Indenture, and no implied
    covenants or obligations shall be read into this Indenture against the
    Trustee; and

         (2)  in the absence of bad faith on its part, the Trustee may
    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed therein, upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture; but in
    the case of any such certificates or opinions which by any provision hereof
    are specifically required to be furnished to the Trustee, the Trustee shall
    be under a duty to examine the same to determine whether or not they
    conform to the requirements of this Indenture.

    (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

    (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that

         (1) this Subsection shall not be construed to limit the effect of
    Subsection (a) of this Section 9.01.

         (2) the Trustee shall not be liable for any error of judgment made in
    good faith by a Responsible Officer, unless it shall be proved that the
    Trustee was negligent in ascertaining the pertinent facts;

         (3) the Trustee shall not be liable with respect to any action taken
    or omitted to be taken by it in good faith in accordance with the direction
    of the Holders of not less than a majority in principal amount of the Notes
    at the time outstanding, determined as provided in Section 10.04, relating
    to the time, method and place of conducting any


                                         -67-



    proceeding for any remedy available to the Trustee, or exercising any trust
    or power conferred upon the Trustee, under this Indenture with respect to
    the Notes; and


         (4) no provision of this Indenture shall require the Trustee to expend
    or risk its own funds or otherwise incur any financial liability in the
    performance of any of its duties hereunder, or in the exercise of any of
    its rights or powers, if it shall have reasonable grounds for believing
    that repayment of such funds or adequate indemnity against such risk or
    liability is not reasonably assured to it.

         (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 9.01.

         SECTION 9.02.  NOTICE OF DEFAULTS.  Within 90 days after the
occurrence of any default hereunder the Trustee shall transmit by mail to all
Holders as their names and addresses appear in the Note register, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; PROVIDED, HOWEVER, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest on any Note or in
the payment of any sinking fund installment with respect to any Notes, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of such Notes; and PROVIDED,
FURTHER, that in the case of any default of the character specified in Section
8.01(3), no such notice to Holders shall be given until at least 30 days after
occurrence thereof.  For the purpose of this Section 9.02, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default.

         SECTION 9.03.  CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of
Section 9.01:

         (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;


                                         -68-



         (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by an Officers' Certificate and any resolution of the
Board of Directors may be sufficiently evidenced by a Board Resolution;

         (c) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (d) the Trustee may consult with counsel and the written advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon;

         (e) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

         (f) prior to the occurrence of an Event of Default and after the
curing or waiving of all such Events of Default which may have occurred, the
Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report,
notice, request, direction, consent, order, approval or other paper or document,
or the books and records of the Company, unless requested in writing to do so by
the Holders of a majority in aggregate principal amount of the Notes then
outstanding; PROVIDED, HOWEVER, that if the payment within a reasonable time to
the Trustee of the costs, expenses or liabilities likely to be incurred by it in
the making of such investigation is not, in the opinion of the Trustee,
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to so proceeding; the reasonable expense
of every such investigation shall be paid by the Company or, if paid by the
Trustee, shall be repaid by the Company upon demand; and

         (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be


                                         -69-



responsible for any misconduct or negligence on the part of any agent or
attorney appointed with due care by it hereunder.

         SECTION 9.04.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF NOTES.  The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and the Trustee
or any Authenticating Agent assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Notes.  Neither the Trustee nor any Authenticating Agent
shall be accountable for the use or application by the Company of Notes or the
proceeds thereof.

         SECTION 9.05.  MAY HOLD NOTES.  The Trustee, any Authenticating Agent,
any Paying Agent, any Note registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Notes and,
subject to Sections 9.08 and 9.13, may otherwise deal with the Company with the
same rights it would have if it were not Trustee, Authenticating Agent, Paying
Agent, Note registrar or such other agent.

         SECTION 9.06.  MONEY HELD IN TRUST.  Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law.  The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.

         SECTION 9.07.  COMPENSATION AND REIMBURSEMENT. The Company agrees:

         (1) to pay to the Trustee from time to time reasonable compensation
    for all services rendered by it hereunder (which compensation shall not be
    limited by any provision of law in regard to the compensation of a trustee
    of an express trust);

         (2) except as otherwise expressly provided herein, to reimburse the
    Trustee upon its request for all reasonable expenses, disbursements and
    advances incurred or made by the Trustee in accordance with any provision
    of this Indenture (including the reasonable compensation and the expenses
    and disbursements of its agents and counsel), except any such expense,
    disbursement or advance as may be attributable to its negligence or bad
    faith; and

         (3) to indemnity the Trustee for, and to hold it harmless against, any
    loss, liability or expense incurred without negligence or bad faith on its
    part, arising out of


                                         -70-



    or in connection with the acceptance or administration of the trust or
    trusts hereunder, including the costs and expenses of defending itself
    against any claim or liability in connection with the exercise or
    performance of any its powers or duties hereunder.

         The provisions of this Section 9.07 shall survive this Indenture.

         SECTION 9.08.  DISQUALIFICATION; CONFLICTING INTERESTS.

         (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section 9.08, with respect to the Notes, it shall, within 90
days after ascertaining that it has such conflicting interest, either eliminate
such conflicting interest or resign in the manner and with the effect
hereinafter specified in this Article Nine.

         (b) In the event that the Trustee shall fail to comply with the
provisions of Subsection (a) of this Section 9.08, the Trustee shall, within 10
days after the expiration of such 90-day period, transmit by mail to all Holders
as their names and addresses appear in the Note registrar, notice of such
failure.

         (c) For the purposes of this Section 9.08, the Trustee shall be deemed
to have a conflicting interest with respect to the Notes if

         (1) the Trustee is trustee under another indenture under which any
    securities, or certificates of interest or participation in any other
    securities, of the Company are outstanding, unless such other indenture is
    a collateral trust indenture under which the only collateral consists of
    Notes, PROVIDED that there shall be excluded from the operation of this
    paragraph this Indenture with respect to any other indenture or indenture
    under which securities, or certificates of interest or participation in
    other securities, of the Company are outstanding, if

              (i) this Indenture and such other indenture or indentures are
         wholly unsecured and such other indenture or indentures are hereafter
         qualified under the TIA, unless the Securities and Exchange Commission
         shall have found and declared by order pursuant to Section 305(b) or
         Section 307(c) of the TIA that differences exist between the
         provisions of this Indenture and the provisions of such other
         indenture or indentures which are so likely to involve a material
         conflict of interest as to make it necessary in the public interest or
         for the protection of investors to


                                         -71-



         disqualify the Trustee from acting as such under this Indenture with
         respect to such other indenture or indentures, or

              (ii) the Company shall have sustained the burden of proving, on
         application to the Securities and Exchange Commission and after
         opportunity for hearing thereon, that trusteeship under this Indenture
         with respect to such other indenture or indentures is not so likely to
         involve a material conflict of interest as to make it necessary in the
         public interest or for the protection of investors to disqualify the
         Trustee from acting as such under this Indenture with respect to such
         other indenture or indentures;

         (2)  the Trustee or any of its directors or executive officers is an
    obligor upon the Notes or an underwriter for the Company;

         (3)  the Trustee directly or indirectly controls or is directly or
    indirectly controlled by or is under direct or indirect common control with
    the Company or an underwriter for the Company;

         (4)  the Trustee or any of its directors or executive officers is a
    director, officer, partner, employee, appointee or representative of the
    Company, or of an underwriter (other than the Trustee itself) for the
    Company who is currently engaged in the business of underwriting, except
    that (i) one individual may be a director or an executive officer, or both,
    of the Trustee and a director or an executive officer, or both, of the
    Company but may not be at the same time an executive officer of both the
    Trustee and the Company; (ii) if and so long as the number of directors of
    the Trustee in office is more than nine, one additional individual may be a
    director or an executive officer, or both, of the Trustee and a director of
    the Company; and (iii) the Trustee may be designated by the Company or by
    any underwriter for the Company to act in the capacity of transfer agent,
    registrar, custodian, paying agent, fiscal agent, escrow agent or
    depositary, or in any other similar capacity, or, subject to the provisions
    of paragraph (1) of this Subsection, to act as trustee, whether under an
    indenture or otherwise;

         (5)  10% or more of the voting securities of the Trustee is
    beneficially owned either by the Company or by any director, partner or
    executive officer thereof, or 20% or more of such voting securities is
    beneficially owned, collectively, by any two or more of such persons; or
    10% or


                                         -72-



    more of the voting securities of the Trustee is beneficially owned either
    by an underwriter for the Company or by any director, partner or executive
    officer thereof, or is beneficially owned, collectively, by any two or more
    such persons;

         (6)  the Trustee is the beneficial owner of, or holds as collateral
    security for an obligation which is in default (as hereinafter in this
    Subsection defined), (i) 5% or more of the voting securities, or 10% or
    more of any other class of security, of the Company not including the Notes
    and securities issued under any other indenture under which the Trustee is
    also trustee, or (ii) 10% or more of any class of security of an
    underwriter for the Company;

         (7)  the Trustee is the beneficial owner of, or holds as collateral
    security for an obligation which is in default (as hereinafter in this
    Subsection defined), 5% or more of the voting securities of any person who,
    to the knowledge of the Trustee, owns 10% or more of the voting securities
    of, or controls directly or indirectly or is under direct or indirect
    common control with, the Company;

         (8)  the Trustee is the beneficial owner of, or holds as collateral
    security for an obligation which is in default (as hereinafter in this
    Subsection defined), 10% or more of any class of security of any person
    who, to the knowledge of the Trustee, owns 50% or more of the voting
    securities of the Company; or

         (9)  the Trustee owns, on May 15 in any calendar year, in the capacity
    of executor, administrator, testamentary or inter vivos trustee, guardian,
    committee or conservator, or in any other similar capacity, an aggregate of
    25% or more of the voting securities, or of any class of security, of any
    person, the beneficial ownership of a specified percentage of which would
    have constituted a conflicting interest under paragraph (6), (7) or (8) of
    this Subsection.  As to any such securities of which the Trustee acquired
    ownership through becoming executor, administrator or testamentary trustee
    of an estate which included them, the provisions of the preceding sentence
    shall not apply, for a period of two years from the date of such
    acquisition, to the extent that such securities included in such estate do
    not exceed 25% of such voting securities or 25% of any such class of
    security.  Promptly after May 15 in each calendar year, the Trustee shall
    make a check of its holdings of such securities in any of the
    above-mentioned capacities as of such May 15.  If the Company fails to make
    payment in full of the principal of (or premium, if any) or interest on any


                                         -73-



    of the Notes when and as the same becomes due and payable, and such failure
    continues for 30 days thereafter, the Trustee shall make a prompt check of
    its holdings of such securities in any of the above-mentioned capacities as
    of the date of the expiration of such 30-day period, and after such date,
    notwithstanding the foregoing provisions of this paragraph, all such
    securities so held by the Trustee, with sole or joint control over such
    securities vested in it, shall, but only so long as such failure shall
    continue, be considered as though beneficially owned by the Trustee for the
    purposes of paragraphs (6), (7) and (8) of this Subsection.

         The specification of percentages in paragraphs (5) to (9), inclusive,
of this Subsection shall not be construed as indicating that the ownership of
such percentages of the securities of a person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this Subsection.

         For the purposes of paragraphs (6), (7), (8) and (9) of this
Subsection only, (i) the terms "security" and "securities" shall include only
such securities as are generally known as corporate securities, but shall not
include any note or other evidence of indebtedness issued to evidence an
obligation to repay moneys lent to a person by one or more banks, trust
companies or banking firms, or any certificate of interest or participation in
any such note or evidence of indebtedness; (ii) an obligation shall be deemed to
be "in default" when a default in payment of principal shall have continued for
30 days or more and shall not have been cured; and (iii) the Trustee shall not
be deemed to be the owner or holder of (A) any security which it holds as
collateral security, as trustee or otherwise, for an obligation which is not in
default as defined in clause (ii) above, or (B) any security which it holds as
collateral security under this Indenture, irrespective of any default hereunder,
or (C) any security which it holds as agent for collection, or as custodian,
escrow agent or depositary, or in any similar representative capacity.

         (d)  For the purposes of this Section 9.08:

         (1)  The term "underwriter", when used with reference to the Company,
    means every person who, within three years prior to the time as of which
    the determination is made, has purchased from the Company with a view to,
    or has offered or sold for the Company in connection with, the distribution
    of any security of the Company outstanding at such time, or has
    participated or has had a direct or indirect participation in any such
    undertaking, or has participated or has had a




                                         -74-



    participation in the direct or indirect underwriting of any such 
    undertaking, but such term shall not include a person whose 
    interest was limited to a commission from an underwriter or 
    dealer not in excess of the usual and customary distributors' 
    or sellers' commission.

         (2)  The term "director" means any director of a corporation or any
    individual performing similar functions with respect to any organization,
    whether incorporated or unincorporated.

         (3)  The term "person" means an individual, a corporation, a
    partnership, an association, a joint-stock company, a trust, an
    unincorporated organization or a government or political subdivision
    thereof.  As used in this paragraph, the term "trust" shall include only a
    trust where the interest or interests of the beneficiary or beneficiaries
    are evidenced by a security.

         (4)  The term "voting security" means any security presently entitling
    the owner or holder thereof to vote in the direction or management of the
    affairs of a person, or any security issued under or pursuant to any trust,
    agreement or arrangement whereby a trustee or trustees or agent or agents
    for the owner or holder of such security are presently entitled to vote in
    the direction or management of the affairs of a person.

         (5)  The term "Company" means any obligor upon the Notes.

         (6)  The term "executive officer" means the president, every vice
    president, every trust officer, the cashier, the secretary and the
    treasurer of a corporation, and any individual customarily performing
    similar functions with respect to any organization whether incorporated or
    unincorporated, but shall not include the chairman of the board of
    directors.

         (e)  The percentages of voting securities and other securities
specified in this Section 9.08 shall be calculated in accordance with the
following provisions:

         (1)  A specified percentage of the voting securities of the Trustee,
    the Company or any other person referred to in this Section 9.08 (each of
    whom is referred to as a "person" in this paragraph) means such amount of
    the outstanding voting securities of such person as entitles the holder or
    holders thereof to cast such specified percentage of the aggregate votes
    which the holders of all the outstanding


                                         -75-



    voting securities of such person are entitled to cast in the direction or
    management of the affairs of such person.

         (2)  A specified percentage of a class of securities of a person means
    such percentage of the aggregate amount of securities of the class
    outstanding.

         (3)  The term "amount", when used in regard to securities, means the
    principal amount if relating to evidences of indebtedness, the number of
    shares if relating to capital shares and the number of units if relating to
    any other kind of security.

         (4)  The term "outstanding" means issued and not held by or for the
    account of the issuer.  The following securities shall not be deemed
    outstanding within the meaning of this definition:

              (i)  securities of an issuer held in a sinking fund relating to
         securities of the issuer of the same class;

             (ii)  securities of an issuer held in a sinking fund relating to
         another class of securities of the issuer, if the obligation evidenced
         by such other class of securities is not in default as to principal or
         interest or otherwise;

            (iii)  securities pledged by the issuer thereof as security for an
         obligation of the issuer not in default as to principal or interest or
         otherwise; and

             (iv)  securities held in escrow if placed in escrow by the issuer
         thereof;

    PROVIDED, HOWEVER, that any voting securities of an issuer shall be deemed
    outstanding if any person other than the issuer is entitled to exercise the
    voting rights thereof.

         (5)  A security shall be deemed to be of the same class as another
    security if both securities confer upon the holder or holders thereof
    substantially the same rights and privileges; PROVIDED, HOWEVER, that, in
    the case of secured evidences of indebtedness, all of which are issued
    under a single indenture, differences in the interest rates or maturity
    dates of various series thereof shall not be deemed sufficient to
    constitute such series different classes and PROVIDED, FURTHER, that, in
    the case of unsecured evidences of indebtedness, differences in the
    interest rates or maturity dates thereof shall not be deemed sufficient to

                                         -76-



    constitute them securities of different classes, whether or not they are
    issued under a single indenture.

         SECTION 9.09.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.  There shall
at all times be a Trustee hereunder which shall be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000
subject to supervision or examination by Federal or State authority and having
its Corporate Trust Office in Chicago, Illinois or New York, New York, to the
extent there is such an institution eligible and willing to serve.  If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the
purposes of this Section 9.09, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
9.09, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article Nine.

         SECTION 9.10.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.


         (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article Nine shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 9.11.

         (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If the instrument of acceptance by a successor Trustee
required by Section 9.11 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         (c)  The Trustee may be removed at any time by the Holders of a
majority in aggregate principal amount of the Notes then outstanding, delivered
to the Trustee and to the Company.

         (d)  If at any time:

         (1)  the Trustee shall fail to comply with Section 9.08(a) after
    written request therefor by the Company or by


                                         -77-



    any Holder who has been a bona fide Holder of a Note for at least six
    months, or

         (2)  the Trustee shall cease to be eligible under Section 9.09 and
    shall fail to resign after written request therefor by the Company or by
    any such Holder, or

         (3)  the Trustee shall become incapable of acting or shall be adjudged
    a bankrupt or insolvent or a receiver of the Trustee or of its property
    shall be appointed or any public officer shall take charge or control of
    the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 8.13, any Holder who has been a bona fide
Holder of a Note for at least six months may, on behalf of such Holder and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee or Trustees.

         (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or
Trustees and shall comply with the applicable requirements of Section 9.11.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by the
Holders of a majority in aggregate principal amount of the Notes then
outstanding delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 9.11, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner required by Section 9.11, any
Holder who has been a bona fide Holder of a Note for at least six months may, on
behalf of such Holder and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders as their names and addresses appear in the Note register.  Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.


                                         -78-



         SECTION 9.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)  Every successor Trustee shall execute, acknowledge and deliver to
the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

         (b)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) of this Section 9.11.

         (c)  No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article Nine.

         SECTION 9.12.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.  Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

         SECTION 9.13.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         (a)  Subject to Subsection (b) of this Section 9.13, if the Trustee
shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company within four months prior to a default, as defined in
Subsection (c) of this


                                         -79-



Section 9.13, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the Notes
and the holders of other indenture securities, as defined in Subsection (c) of
this Section 9.13:

         (1)  an amount equal to any and all reductions in the amount due and
    owing upon any claim as such creditor in respect of principal or interest,
    effected after the beginning of such four months' period and valid as
    against the Company and its other creditors, except any such reduction
    resulting from the receipt or disposition of any property described in
    paragraph (2) of this Subsection, or from the exercise of any right of
    set-off which the Trustee could have exercised if a petition in bankruptcy
    had been filed by or against the Company upon the date of such default; and

         (2)  all property received by the Trustee in respect of any claims as
    such creditor, either as security therefor, or in satisfaction or
    composition thereof, or otherwise, after the beginning of such four months'
    period, or an amount equal to the proceeds of any such property, if
    disposed of, subject, however, to the rights, if any, of the Company and
    its other creditors in such property or such proceeds.

         Nothing herein contained, however, shall affect the right of the
Trustee:

         (A)  to retain for its own account (i) payments made on account of any
    such claim by any Person (other than the Company) who is liable thereon,
    and (ii) the proceeds of the bona fide sale of any such claim by the
    Trustee to a third Person, and (iii) distributions made in cash, securities
    or other property in respect of claims filed against the Company in
    bankruptcy or receivership or in proceedings for reorganization pursuant to
    the Federal Bankruptcy Act or applicable State law;

         (B)  to realize, for its own account, upon any property held by it as
    security for any such claim, if such property was so held prior to the
    beginning of such four months' period;

         (C)  to realize, for its own account, but only to the extent of the
    claim hereinafter mentioned, upon any property held by it as security for
    any such claim, if such claim was created after the beginning of such four
    months' period and such property was received as security therefor


                                         -80-



    simultaneously with the creation thereof, and if the Trustee shall sustain
    the burden of proving that at the time such property was so received the
    Trustee had no reasonable cause to believe that a default, as defined in
    Subsection (c) of this Section 9.13, would occur within four months; or

         (D)  to receive payment on any claim referred to in paragraph (B) or
    (C), against the release of any property held as security for such claim as
    provided in paragraph (B) or (C), as the case may be, to the extent of the
    fair value of such property.

         For the purposes of paragraphs (B), (C) and (D), property substituted
after the beginning of such four months' period for property held as security at
the time of such substitution shall, to the extent of the fair value of the
property released, have the same status as the property released, and, to the
extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such pre-existing claim.

         If the Trustee shall be required to account, the funds and property 
held in such special account and the proceeds thereof shall be apportioned 
among the Trustee, the Holders and the holders of other indenture securities 
in such manner that the Trustee, the Holders and the holders of other 
indenture securities realize, as a result of payments from such special 
account and payments of dividends on claims filed against the Company in 
bankruptcy or receivership or in proceedings for reorganization pursuant to 
the Federal Bankruptcy Act or applicable State law, the same percentage of 
their respective claims, figured before crediting to the claim of the Trustee 
anything on account of the receipt by it from the Company of the funds and 
property in such special account and before crediting to the respective 
claims of the Trustee and the Holders and the holders of other indenture 
securities dividends on claims filed against the Company in bankruptcy or 
receivership or in proceedings for reorganization pursuant to the Federal 
Bankruptcy Act or applicable State law, but after crediting thereon receipts 
on account of the indebtedness represented by their respective claims from 
all sources other than from such dividends and from the funds and property so 
held in such special account.  As used in this paragraph, with respect to any 
claim, the term "dividends" shall include any distribution with respect to 
such claim, in bankruptcy or receivership or proceedings for reorganization 
pursuant to the Federal Bankruptcy Act or applicable State law, whether such 
distribution is made in cash, securities or other property, but shall not 
include any such

                                         -81-



distribution with respect to the secured portion, if any, of such claim.  The 
court in which such bankruptcy, receivership or proceedings for 
reorganization is pending shall have jurisdiction (i) to apportion among the 
Trustee, the Holders and the holders of other indenture securities, in 
accordance with the provisions of this paragraph, the funds and property held 
in such special account and proceeds thereof, or (ii) in lieu of such 
apportionment, in whole or in part, to give to the provisions of this 
paragraph due consideration in determining the fairness of the distributions 
to be made to the Trustee and the Holders and the holders of other indenture 
securities with respect to their respective claims, in which event it shall 
not be necessary to liquidate or to appraise the value of any securities or 
other property held in such special account or as security for any such 
claim, or to make a specific allocation of such distributions as between the 
secured and unsecured portions of such claims, or otherwise to apply the 
provisions of this paragraph as a mathematical formula.

         Any Trustee which has resigned or been removed after the beginning of
such four months' period shall be subject to the provisions of this Subsection
as though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such four months' period, it
shall be subject to the provisions of this Subsection if and only if the
following conditions exist:

         (i)  the receipt of property or reduction of claim, which would have
    given rise to the obligation to account, if such Trustee had continued as
    Trustee, occurred after the beginning of such four months' period; and

         (ii)  such receipt of property or reduction of claim occurred within
    four months after such resignation or removal.

         (b)  There shall be excluded from the operation of Subsection (a) of
this Section 9.13 a creditor relationship arising from:

         (1)  the ownership or acquisition of securities issued under any
    indenture, or any security or securities having a maturity of one year or
    more at the time of acquisition by the Trustee;

         (2)  advances authorized by a receivership or bankruptcy court of
    competent jurisdiction or by this Indenture, for the purposes of preserving
    any property which shall at any time be subject to the lien of this
    Indenture or of discharging tax liens or other prior liens or


                                         -82-



    encumbrances thereon, if notice of such advances and of the circumstances
    surrounding the making thereof is given to the Holders at the time and in
    the manner provided in this Indenture;

         (3)  disbursements made in the ordinary course of business in the
    capacity of trustee under an indenture, transfer agent, registrar,
    custodian, paying agent, fiscal agent or depositary, or other similar
    capacity;

         (4)  an indebtedness created as a result of services rendered or
    premises rented; or an indebtedness created as a result of goods or
    securities sold in a cash transaction, as defined in Subsection (c) of this
    Section 9.13;

         (5)  the ownership of stock or of other securities of a corporation
    organized under the provisions of Section 25(a) of the Federal Reserve Act,
    as amended, which is directly or indirectly a creditor of the Company; and

         (6)  the acquisition, ownership, acceptance or negotiation of any
    drafts, bills of exchange, acceptances or obligations which fall within the
    classification of self-liquidating paper, as defined in Subsection (c) of
    this Section 9.13.

         (c)  For the purposes of this Section 9.13 only:

         (1)  the term "default" means any failure to make payment in full of
    the principal of or interest on any of the Notes or upon the other
    indenture securities when and as such principal or interest becomes due and
    payable;

         (2)  the term "other indenture securities" means securities upon which
    the Company is an obligor outstanding under any other indenture (i) under
    which the Trustee is also trustee, (ii) which contains provisions
    substantially similar to the provisions of this Section 9.13, and (iii)
    under which a default exists at the time of the apportionment of the funds
    and property held in such special account;

         (3)  the term "cash transaction" means any transaction in which full
    payment for goods or securities sold is made within seven days after
    delivery of the goods or securities in currency or in checks or other
    orders drawn upon banks or bankers and payable upon demand;

         (4)  the term "self-liquidating paper" means any draft, bill of
    exchange, acceptance or obligation which is made,


                                         -83-



    drawn, negotiated or incurred by the Company for the purpose of financing
    the purchase, processing, manufacturing, shipment, storage or sale of
    goods, wares or merchandise and which is secured by documents evidencing
    title to, possession of, or a lien upon, the goods, wares or merchandise or
    the receivables or proceeds arising from the sale of the goods, wares or
    merchandise previously constituting the security, provided the security is
    received by the Trustee simultaneously with the creation of the creditor
    relationship with the Company arising from the making, drawing, negotiating
    or incurring of the draft, bill of exchange, acceptance or obligation;

         (5)  the term "Company" means any obligor upon the Notes; and

         (6)  the term "Federal Bankruptcy Act" means the Bankruptcy Act or
    Title 11 of the United States Code.

         SECTION 9.14.  APPOINTMENT OF AUTHENTICATING AGENT.  At any time when
any of the Notes remain outstanding the Trustee may appoint an Authenticating
Agent or Agents with respect to the Notes which shall be authorized to act on
behalf of the Trustee to authenticate Notes issued upon exchange, registration
of transfer or partial redemption thereof or pursuant to Section 2.06, and Notes
so authenticated shall be entitled to the benefits of this Indenture and shall
be valid and obligatory for all purposes as if authenticated by the Trustee
hereunder.  Wherever reference is made in this Indenture to the authentication
and delivery of Notes by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or State authority.  If such Authenticating Agent publishes reports
of condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section 9.14,
the combined capital and surplus of such Authenticating Agent shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section 9.14, such
Authenticating


                                         -84-



Agent shall resign immediately in the manner and with the effect specified in
this Section 9.14.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 9.14, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 9.14, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders as their names and addresses appear in the Note register.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section 9.14.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 9.14, and the

                              CONCERNING THE NOTEHOLDERS

         SECTION 10.01.  ACTION BY NOTEHOLDERS.  (a)  Whenever in this
Indenture it is provided that the holders of a specified percentage in aggregate
principal amount of the Notes may take any action (the making of any demand or
request, or the giving of any notice, consents or waivers in lieu of a
Noteholders' meeting or the taking of any other action) the fact that at the
time of taking any such action the Holders of such specified percentage have
joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by such Noteholders in person or by agent
or proxy appointed in writing, or (b) by the record of such Noteholders voting
in favor thereof at any meeting of Noteholders duly called and held in
accordance with Article Eleven, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Noteholders.

         (b)  Whenever in this Indenture it is provided that the Holders of a
specified percentage in aggregate principal amount of the Notes may take any
action, any party designated in writing by the Depositary, or by any party so
designated by the Depositary, as the owner of a beneficial interest of a
specified principal amount of any Global Note held by such Depositary shall be
deemed to be a Holder of Notes in such principal amount for such purpose.


                                         -86-



         SECTION 10.02.  PROOF OF EXECUTION BY NOTEHOLDERS.

         (a)  Subject to Sections 9.01 and 11.05, proof of the execution of any
instruments by a Noteholder or the agent or proxy for such Noteholder shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee.  The ownership of Notes shall be proved by the Note register of the
Company or by a certificate of the Note registrar.

         (b)  The record of any Noteholders' meeting shall be proven in the
manner provided for in Section 11.06.

         SECTION 10.03.  WHO DEEMED ABSOLUTE OWNERS.  Subject to Sections
2.04(f) and 10.01, the Company, the Trustee, any Authenticating Agent and Note
registrar may deem the person in whose name any Note shall be registered upon
the Note register of the Company to be, and may treat such person as, the
absolute owner of such Note (whether or not such Note shall be overdue) for the
purpose of receiving payment of or on account of the principal of and any
premium and interest on such Note, and for all other purposes; and neither the
Company nor the Trustee nor any Authenticating Agent nor any Note registrar
shall be affected by any notice to the contrary.  All such payments shall be
valid and effectual to satisfy and discharge the liability upon any such Note to
the extent of the sum or sums so paid.

         SECTION 10.04.  COMPANY-OWNED NOTES DISREGARDED.  In determining
whether the Holders of the requisite aggregate principal amount of Notes then
outstanding have concurred in any direction, consent or waiver under this
Indenture, Notes which are owned by the Company or any other obligor on the
Notes or by any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any other obligor on
the Notes shall be disregarded and deemed not to be outstanding for the purpose
of any such determination; PROVIDED that for the purposes of determining whether
the Trustee shall be protected in relying on any such direction, consent or
waiver only Notes which the Trustee knows are so owned shall be so disregarded.
Notes so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 10.04 if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right to vote such
Notes and that the pledgee is not a person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
such other obligor.  In the case of a dispute as to such right, any decision by
the Trustee taken upon the advice of counsel shall be full protection to the
Trustee.

         SECTION 10.05.  REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.  At any
time prior to the taking of any action by the holders of the percentage in
aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any Holder of a Note, which is shown by the
evidence to be included in the Notes the Holders of which have consented to such
action may, by filing written notice with the Trustee at the Corporate Trust
Office of the Trustee and upon proof of ownership as provided in Section
10.02(a), revoke such action so far as it concerns such Note.  Except as
aforesaid any such action taken by the Holder of any Note shall be conclusive
and binding upon such Holder and upon all future Holders and owners of such Note
and of any Notes issued in exchange or substitution therefor, irrespective of
whether or not any notation thereof is made upon such Note or such other Notes.

         SECTION 10.06.  RECORD DATE FOR NOTEHOLDER ACTS.  If the Company shall
solicit from the Noteholders any request, demand, authorization, direction,
notice, consent, waiver or other act, the Company may, at its option, by Board
Resolution, fix in advance a record date in compliance with TIA Section 3.16(c)
for the determination of Noteholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other act, but the Company
shall have no obligation to do so.  If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other act
may be given before or after the record date, but only the Noteholders of record
at the close of business on the record date shall be deemed to be Noteholders
for the purpose of determining whether Holders of the requisite aggregate
principal amount of Notes then outstanding have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other act, and for that purpose the outstanding Notes shall be
computed as of the record date; PROVIDED, HOWEVER, that no such authorization,
agreement or consent by the Noteholders on the record date shall be deemed
effective unless it shall become effective pursuant to this Indenture not later
than six months after the record date.

and secretary of the meeting and one of the duplicates shall be delivered to the

    the Company is merged (the "successor corporation") or the Person
    which acquires by conveyance or transfer, or which leases, the
    properties and assets of the Company substantially as an entirety
    shall be a corporation organized and existing under the laws of the
    United States of America or any State or


                                         -91-



    the District of Columbia, and shall expressly assume, by an indenture
    supplemental hereto, executed and delivered to the Trustee, in form
    satisfactory to the Trustee, the due and punctual payment of the principal
    of (and premium, if any) and interest on all Notes and the performance of
    every covenant of this Indenture on the part of the Company to be performed
    or observed;

         (2)  immediately after giving effect to such consolidation,
    merger, conveyance, transfer or lease, no Event of Default, and no
    event which, after notice or lapse of time, or both, would become an
    Event of Default, shall have occurred and be continuing;

    transfer or lease, properties or assets of the Company would become subject
    to a mortgage, pledge, lien, security interest or other encumbrance which
    would not otherwise be permitted by this Indenture without making effective
    provision whereby the Notes then outstanding and any other indebtedness of
    the Company then entitled thereto will be equally and ratably secured with
    any and all indebtedness and obligations secured thereby, the Company or
    the successor corporation or Person, as the case may be, will take such
    action as will be necessary effectively to secure all Notes equally and
    ratably with (or prior to) all indebtedness secured thereby; and

         (4)  the Company has delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel each stating that such
    consolidation, merger, conveyance, transfer or lease and such
    supplemental indenture comply with this Article Twelve and that all
    conditions precedent herein provided for relating to such
    consolidation, merger, conveyance or transfer have been complied with.

         SECTION 12.02.  SUCCESSOR CORPORATION SUBSTITUTED.  Upon any
consolidation or merger, or any conveyance, transfer or lease as an entirety in
accordance with Section 12.01, the successor corporation formed by such
consolidation or into which the Company is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor corporation had been named as the Company
herein; PROVIDED, HOWEVER, that no such conveyance or transfer shall have the
effect of releasing the Person named as the "Company" in the first paragraph of
this Indenture or any successor corporation which shall theretofore


                                         -92-



have become such in the manner prescribed in this Article Twelve from its
liability as obligor and maker on any of the Notes.

         (a)  Upon any application or demand by the Company to the Trustee to

for in this Indenture relating to the proposed action have been complied with

delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this Indenture shall include (1) a statement that each Person
making such certificate or opinion has read such covenant or condition and the
definitions relating thereto; (2) a brief statement as to the nature and scope

with respect to the matters upon which such certificate or opinion is based are
erroneous.  Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or

Company, unless such person knows, or in the exercise of reasonable care should
know, that the certificate or

firm of accountants, unless such officer or counsel, as the case may be, knows
that the certificate or opinion or representations with respect to the
accounting matters upon which the certificate, statement or opinion of such
officer or counsel may be based as aforesaid are erroneous, or in the exercise
of reasonable care should know that the same are erroneous.  Any certificate or

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 15.06.  BUSINESS DAYS.  Unless otherwise provided herein, in
any case where the date of Maturity of the principal of or any premium or
interest on any Note or the Redemption Date of any Note is not a Business Day,

or demand which by any provision of this Indenture is required or permitted to
be given or served by the Trustee or the Company to or on the Holders of Notes,
as the case may be, shall be given or served by first-class mail, postage
prepaid, addressed to the Holders of such Notes at their last addresses as the

referred to on the reverse hereof), for value received, hereby promises to pay

currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts, on the Maturity date specified
above and to pay interest thereon, in such coin or currency, from and including
the Original Issue Date (or if this Global Note has two or more Original Issue
Dates, interest shall, beginning on each such Original Issue Date, begin to
accrue for that part of the principal amount to which such Original Issue Date
is applicable) specified above, or from and including the most recent Interest
Payment Date specified above to which interest has been paid or duly provided
for, as the case may be.  Interest shall be paid in arrears semiannually on each
Interest Payment Date  in each year commencing on (a) the first such Interest
Payment Date next succeeding the earliest Original Issue Date or Dates, or (b)
if such Original Issue Date is after a Record Date and prior to the first
Interest Payment Date, on the second Interest Payment Date, at the per annum
Interest Rate set forth above until Maturity and the principal hereof is paid or

provided for on any Interest Payment Date will, as provided in the Indenture, be
paid to the Person in whose name this Note is registered at the close of
business on the Record Date specified above next preceding such Interest Payment
Date; PROVIDED, HOWEVER, that if an Original Issue Date falls between a Record

respect to such Original Issue Date will be paid on the second Interest Payment
Date subsequent to such Original Issue Date to the Person in whose name this
Note is registered at the close of business on the Record Date for such second
Interest Payment Date; and PROVIDED, FURTHER, that interest payable on the
Maturity date or, if applicable, upon redemption, shall be payable to the Person
to whom principal shall be payable.  Except as otherwise provided in the
Indenture, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Record Date and shall be
paid to the Person in whose name this Note is registered at the close of
business on a Record Date for the payment of such defaulted interest to be fixed
by the Company, notice whereof shall be given to Noteholders not less than
fifteen days prior to such Record Date.  Payment of the principal of and any
premium and interest on this Note shall be made on or before 10:30 A.M., New

Depositary, of the day on which such payment is due, by wire transfer into the
account specified by the Depositary; PROVIDED, HOWEVER, that as a condition to
the payment at the Maturity date of any part of the principal and any applicable
premium of this Global Note, the Depositary shall surrender, or cause to be

                                   MEDIUM-TERM NOTE

         This Global Note is one of, and a global security which represents
Notes which are part of, the duly authorized Notes of the Company (herein called
the "Notes"), issued and to be issued under an Indenture dated as of __________,
1996 (herein called the "Indenture") between the Company and The First National
Bank of Chicago, as Trustee (herein called the "Trustee", which term includes
any successor Trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Noteholders, and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

         Each Note shall be dated the date of its authentication by the
Trustee.  Each Note shall also bear an Original Issue Date or Dates which with
respect to this Global Note (or any portion thereof) shall mean the date or
dates of the original issue of the Notes represented hereby as specified on the
face hereof, and such Original Issue Date or Dates shall remain the same for all
Notes subsequently issued upon transfer, exchange or substitution of such
original Note (or such subsequently issued Notes) regardless of their dates of
authentication.  The Notes may bear different dates, mature at different times,
bear interest at different dates, be subject to different redemption provisions,
if any, and may otherwise vary, all as provided in the Indenture.

         Interest on this Note will be payable on the Interest Payment Date or
Interest Payment Dates as specified on the face hereof and, in either case, at
Maturity.  Unless otherwise specified on the face hereof, payments on this Note
with respect to any particular Interest Payment Date or the Maturity date will
include interest accrued from and including the applicable Original Issue Date,
or from and including the most recent Interest Payment Date to which interest
has been paid or duly provided for, to but excluding the particular Interest
Payment Date or the Maturity date.  Interest on this Note will be computed and
paid on the basis of a 360-day year of twelve 30-day months.

         Unless otherwise specified on the face hereof, if this Note is an
Amortizing Note, payments with respect to this Note will be applied first to
interest due and payable hereon and then to the reduction of the unpaid
principal amount hereof.  If this Note is an Amortizing Note, a table setting
forth the schedule of


                                         A-4



dates and amounts of payments of principal of and interest on this Note or the
formula for the amortization of principal and/or interest is set forth in an
annex attached to this Note.

         All percentages resulting from any calculation with respect to this
Note will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point (with five one-millionths of a percentage point rounded upward)
and all dollar amounts used in or resulting from any such calculation with
respect to this Note will be rounded to the nearest cent (with one-half cent
being rounded upward).

         "Business Day" means, unless otherwise specified on the face hereof,
any Monday, Tuesday, Wednesday, Thursday or Friday that in The City of New York
is not a day on which banking institutions are authorized or obligated by law,
regulation or executive order to close.  If an Interest Payment Date or Maturity
for this Note falls on a day that is not a Business Day, payment of principal,
premium, if any, and interest to be made on such day with respect to this Note
will be made on the next day that is a Business Day with the same force and
effect as if made on the due date, and no additional interest will be payable on
the date of payment for the period from and after the due date as a result of
such delayed payment.

         This Note will be redeemable at the option of the Company prior to its
Stated Maturity only if an Initial Redemption Date is specified on the face
hereof.  If so specified, this Note will be subject to redemption at the option
of the Company on any date on and after such Initial Redemption Date in whole or
from time to time in part in increments of $1,000 or integral multiples thereof,
at the redemption prices specified in an annex attached to this Note, plus
accrued and unpaid interest to but excluding the date of redemption, but
payments due with respect to this Note prior to the date of redemption will be
payable to the Holder of this Note of record at the close of business on the
relevant Record Date specified on the face hereof, all as provided in the
Indenture.  The Company may exercise such option by causing the Trustee to mail
a notice of such redemption, at least 30 but not more than 60 calendar days
prior to the date of redemption, in accordance with the provisions of the
Indenture.  In the event of redemption of this Note in part only, this Note will
be cancelled and a new Note or Notes representing the unredeemed portion hereof
will be issued in the name of the Holder hereof.  This Note is not subject to a
sinking fund unless otherwise specified in an annex attached hereto.


                                         A-5




         If so specified on the face of this Note, (i) this Note shall be
subject to repayment, in whole or in part, prior to Stated Maturity at the
option of the Holder on a certain date or dates and at a certain price or
prices, plus accrued and unpaid interest to but excluding the date of payment;
(ii) the Stated Maturity of this Note may be extended at the option of the
Company for one or more Extension Periods of from one to five years, as
specified on the face hereof, up to but not beyond the Final Maturity Date
specified on the face hereof; (iii) the interest rate specified on the face
hereof may be reset by the Company in accordance with a formula or otherwise on
the Optional Interest Reset Date or Dates specified on the face hereof; and/or
(iv) this Note shall be renewable at the option of the Holder, in each case in
accordance with the provisions of the Indenture applicable thereto and/or as
specified in an annex attached to this Note.

         Notwithstanding anything herein to the contrary, if this Note is an
Original Issue Discount Note as specified on the face hereof, the amount payable
in the event the principal amount hereof is declared to be due and payable
immediately by reason of an Event of Default or in the event of redemption or
repayment hereof prior to the Stated Maturity hereof, in lieu of the principal
amount due at the Stated Maturity hereof, shall be the Amortized Face Amount of
this Note as of the date of declaration, redemption or repayment, as the case
may be.  The "Amortized Face Amount" of this Note shall be the amount equal to
the principal amount of this Note multiplied by the Issue Price specified on the
face hereof plus (b) the portion of the difference between the dollar amount
thus obtained and the principal amount hereof that has accreted at the Yield to
Maturity specified on the face hereof (computed in accordance with generally
accepted United States bond yield computation principles) to such date of

Amount of this Note exceed the principal amount stated on the face hereof.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Noteholders to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not
less than a majority in aggregate principal amount of the Notes then outstanding
that would be affected thereby.  The Indenture also contains provisions
permitting the Holders of not less than a majority in aggregate principal amount
of the Notes then outstanding, on behalf of the Holders of all Notes, to waive


                                         A-6

Indenture also provides that the Holders of not less than a majority in
aggregate principal amount of the Notes then outstanding may waive certain past
defaults and their consequences on behalf of the Holders of all Notes.  Any such
consent or waiver by the Holder of this Global Note (if not timely revoked in
accordance with the Indenture) shall be conclusive and binding upon such Holder
and upon all future Holders of this Global Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Global Note
or such Note.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Notes will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder, unless such Holder shall have
previously given to the Trustee written notice of a continuing default with
respect to the Notes, the Holders of not less than a majority in aggregate
principal amount of the Notes then outstanding shall have made written request,
and offered reasonable indemnity, to the Trustee to institute such proceeding as
Trustee, and the Trustee shall have failed to institute such proceeding within
60 days; PROVIDED, HOWEVER, that such limitations do not apply to a suit
instituted by the Holder hereof for the enforcement of payment of the principal
of and any premium or interest on this Global Note on or after the respective
due dates expressed herein.

         THIS NOTE IS A GLOBAL NOTE REGISTERED IN THE NAME OF THE DEPOSITARY

FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS GLOBAL NOTE MAY NOT BE
TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY

amended, or any successor statute or regulation, the Company may appoint a
successor Depositary with respect to this Global Note.  If (A) a successor
Depositary for this Global Note is not appointed by the Company within 90 days
after the Company


                                         A-7



receives such notice or becomes aware of such ineligibility, or (B) any Notes
are represented by this Global Note at a time when an Event of Default with
respect to the Notes shall have occurred and be continuing, then in each case

Trustee, upon receipt of a Company Order for the authentication and delivery of
individual Notes in exchange for this Global Note, shall authenticate and make
available for delivery, individual Notes of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of this
Global Note in exchange for this Global Note.

issued in the form of this Global Note, the Depositary for such Global Note
shall surrender this Global Note in exchange in whole or in part for individual
Notes of like tenor and terms in definitive form on such terms as are acceptable
to the Company and such Depositary.  Thereupon the Company shall execute, and
the Trustee shall authenticate and make available for delivery, without a
service charge, (1) to each Person specified by such Depositary, a new Note or
Notes of like tenor and terms, and of any authorized denomination as requested
by such Person in aggregate principal amount equal to and in exchange for the
beneficial interest of such Person in this Global Note, and (2) to such
Depositary a new Global Note of like tenor and terms and in a denomination equal
to the difference, if any, between the principal amount of this Global Note and
the aggregate principal amount of Notes delivered to Holders thereof.

         Under certain circumstances specified in the Indenture, the Depositary
may be required to surrender any two or more Global Notes which have identical
terms (but which may have differing Original Issue Dates) to the Trustee, and
the Company shall execute and the Trustee shall authenticate and deliver to, or
at the direction of, the Depositary a Global Note in principal amount equal to
the aggregate principal amount of, and with all terms identical to, the Global
Notes surrendered to the Trustee, and such new Global Note shall indicate each
applicable Original Issue Date and the principal amount applicable to each such
Original Issue Date.

         No reference herein to the Indenture and no provision of this Global
Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and any premium and
interest on this

Global Note at the times, places and rates, and in the coin or currency, herein
prescribed.

may treat the Person in whose name this Global Note is registered as the owner
hereof for all purposes, whether or not this Global Note is overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

accordance with, the laws of the State of New York.

defaulted interest to be fixed by the Company, notice whereof shall be given to
Noteholders not less than fifteen days prior to such Record Date.  Payment of

                              MIDAMERICAN ENERGY COMPANY
                                  MEDIUM-TERM NOTE

         This Note is one of the duly authorized Notes of the Company (herein
called the "Notes"), issued and to be issued under an Indenture dated as of
__________, 1996 (herein called the "Indenture") between the Company and The
First National Bank of Chicago, as Trustee (herein called the "Trustee", which
term includes any successor Trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Noteholders, and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

         Each Note shall be dated the date of its authentication by the
Trustee.  Each Note shall also bear an Original Issue Date which with respect to
this Note (or any portion thereof) shall mean the date of its original issue as
specified on the face hereof, and such Original Issue Date shall remain the same
for all Notes subsequently issued upon transfer, exchange or substitution of
such original Note (or such subsequently issued Notes) regardless of their dates
of authentication.  The Notes may bear different dates, mature at different
times, bear interest at different dates, be subject to different redemption
provisions, if any, and may otherwise vary, all as provided in the Indenture.

         Interest on this Note will be payable on the Interest Payment Date or
Interest Payment Dates as specified on the face hereof and, in either case, at
Maturity.  Unless otherwise specified on the face hereof, payments on this Note
with respect to any particular Interest Payment Date or the Maturity date will
include interest accrued from and including the Original Issue Date, or from and
including the most recent Interest Payment Date to which interest has been paid
or duly provided for, to but excluding the particular Interest Payment Date or
the Maturity date.  Interest on this Note will be computed and paid on the basis
of a 360-day year of twelve 30-day months.

         Unless otherwise specified on the face hereof, if this Note is an
Amortizing Note, payments with respect to this Note will be applied first to
interest due and payable hereon and then to the reduction of the unpaid
principal amount hereof.  If this Note is an Amortizing Note, a table setting
forth the schedule of dates and amounts of payments of principal of and interest
on this Note or the formula for the amortization of principal and/or interest is
set forth in an annex attached to this Note.


                                         B-4



         All percentages resulting from any calculation with respect to this
Note will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point (with five one-millionths of a percentage point rounded upward)
and all dollar amounts used in or resulting from any such calculation with
respect to this Note will be rounded to the nearest cent (with one-half cent
being rounded upward).

         "Business Day" means, unless otherwise specified on the face hereof,
any Monday, Tuesday, Wednesday, Thursday or Friday that in The City of New York
is not a day on which banking institutions are authorized or obligated by law,
regulation or executive order to close.  If an Interest Payment Date or Maturity
for this Note falls on a day that is not a Business Day, payment of principal,
premium, if any, and interest to be made on such day with respect to this Note
will be made on the next day that is a Business Day with the same force and
effect as if made on the due date, and no additional interest will be payable on
the date of payment for the period from and after the due date as a result of
such delayed payment.

         This Note will be redeemable at the option of the Company prior to its
Stated Maturity only if an Initial Redemption Date is specified on the face
hereof.  If so specified, this Note will be subject to redemption at the option
of the Company on any date on and after such Initial Redemption Date in whole or
from time to time in part in increments of $1,000 or integral multiples thereof,
at the redemption prices specified in an annex attached to this Note, plus
accrued and unpaid interest to but excluding the date of redemption, but
payments due with respect to this Note prior to the date of redemption will be
payable to the Holder of this Note of record at the close of business on the
relevant Record Date specified on the face hereof, all as provided in the
Indenture.  The Company may exercise such option by causing the Trustee to mail
a notice of such redemption, at least 30 but not more than 60 calendar days
prior to the date of redemption, in accordance with the provisions of the
Indenture.  In the event of redemption of this Note in part only, this Note will
be cancelled and a new Note or Notes representing the unredeemed portion hereof
will be issued in the name of the Holder hereof.  This Note is not subject to a
sinking fund unless otherwise specified in an annex attached hereto.

         If so specified on the face of this Note, (i) this Note shall be
subject to repayment, in whole or in part, prior to Stated Maturity at the
option of the Holder on the Optional


                                         B-5



Repayment Date or Dates specified on the face hereof at the Optional 
Repayment Price or Prices specified on the face hereof, plus accrued and 
unpaid interest to but excluding the date of payment; (ii) the Stated 
Maturity of this Note may be extended at the option of the Company for one or 
more Extension Periods of from one to five years, as specified on the face 
hereof, up to but not beyond the Final Maturity Date specified on the face 
hereof; (iii) the interest rate specified on the face hereof may be reset by 
the Company in accordance with a formula or otherwise on the Optional 
Interest Reset Date or Dates specified on the face hereof; and/or (iv) this 
Note shall be renewable at the option of the Holder, in each case in 
accordance with the provisions of the Indenture applicable thereto and/or the 
provisions of an annex attached to this Note.

         Notwithstanding anything herein to the contrary, if this Note is an
Original Issue Discount Note as specified on the face hereof, the amount payable
in the event the principal amount hereof is declared to be due and payable
immediately by reason of an Event of Default or in the event of redemption or
repayment hereof prior to the Stated Maturity hereof, in lieu of the principal
amount due at the Stated Maturity hereof, shall be the Amortized Face Amount of
this Note as of the date of declaration, redemption or repayment, as the case
may be.  The "Amortized Face Amount" of this Note shall be the amount equal to
the principal amount of this Note multiplied by the Issue Price specified on the
face hereof plus (b) the portion of the difference between the dollar amount
thus obtained and the principal amount hereof that has accreted at the Yield to
Maturity specified on the face hereof (computed in accordance with generally
accepted United States bond yield computation principles) to such date of
declaration, redemption or repayment but in no event shall the Amortized Face
Amount of this Note exceed the principal amount stated on the face hereof.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Noteholders to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not
less than a majority in aggregate principal amount of the Notes then outstanding
that could be affected thereby.  The Indenture also contains provisions
permitting the Holders of not less than a majority in aggregate principal amount
of the Notes then outstanding, on behalf of the Holders of all Notes, to waive
compliance by the Company with certain covenants in the Indenture.  The
Indenture also provides that the Holders of not less than a majority in

to on the reverse hereof), for value received, hereby promises to pay to

or registered assigns the principal sum specified above, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts, on the Maturity date specified
above and to pay interest thereon, in such coin or currency, from and including
the Original Issue Date (or if this Global Note has two or more Original Issue
Dates, interest shall, beginning on each such Original Issue Date, begin to
accrue for that part of the principal amount to which such Original Issue Date
is applicable) specified above, or from and including the most recent Interest
Payment Date specified above to which interest has been paid or duly provided
for, as the case may be.  Interest shall be paid in arrears monthly, quarterly,
semiannually or annually as specified above under Interest Payment Dates, on
each Interest Payment Date in each year and at Maturity, commencing on (a) the
first such Interest Payment Date next succeeding the earliest Original Issue
Date or Dates, or (b) if such Original Issue Date is after a Record Date and
prior to the first Interest Payment Date, on the second Interest Payment Date,
at a rate per annum equal to the Initial Interest Rate specified above until the
initial Interest Reset Date specified above, and thereafter at a rate per annum
determined in accordance with the provisions in the Indenture for calculating
the Interest Rate for Notes having the Interest Rate Basis specified above,
until Maturity and the principal hereof is paid or made available for payment.
The interest so payable and punctually paid or duly provided for on any Interest
Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Note is registered at the close of business on the Record Date
specified above next preceding such Interest Payment Date; PROVIDED, HOWEVER,
that if an Original Issue Date falls between a Record Date and the next Interest
Payment Date, the first payment of interest with respect to such Original Issue
Date will be paid on the second Interest Payment Date subsequent to such
Original Issue Date to the Person in whose name this Note is registered at the
close of business on the Record Date for such second Interest Payment Date; and
PROVIDED, FURTHER, that interest payable on the Maturity date or, if applicable,
upon redemption, shall be payable to the Person to whom principal shall be
payable.  Except as otherwise provided in the Indenture, any such interest not
so punctually paid or duly provided for will forthwith cease to be payable to
the Holder on such Record Date and shall be paid to the Person in whose name
this Note is registered at the close of business on a Record Date for the



                                         C-2

shall be given to Noteholders not less than fifteen days prior to such Record
Date.  Payment of the principal of and any premium and interest on this Note

Maturity date of any part of the principal and any applicable premium of this
Global Note, the Depositary shall surrender, or cause to be surrendered, this
Global Note to the Trustee.  The Company will pay any administrative costs
imposed by banks in connection with making payments by wire transfer, but not

same Original Issue Date or Dates, Maturity date, Interest Rate and redemption
and other provisions as provided herein or in the Indenture.

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS GLOBAL NOTE
SET FORTH IN FULL ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL
PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by 
the Trustee referred to on the reverse hereof, directly or through an 
Authenticating Agent, by manual signature of an authorized signatory, this 
Note shall not be entitled to any benefit under the Indenture or be valid or

                              MIDAMERICAN ENERGY COMPANY
                                   MEDIUM-TERM NOTE

         This Global Note is one of, and a global security which represents
Notes which are part of, the duly authorized Notes of the Company (herein called
the "Notes"), issued and to be issued under an Indenture dated as of __________,
1996 (herein called the "Indenture") between the Company and The First National
Bank of Chicago, as Trustee (herein called the "Trustee", which term includes
any successor Trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Noteholders, and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

         Each Note shall be dated the date of its authentication by the
Trustee.  Each Note shall also bear an Original Issue Date or Dates which with
respect to this Global Note (or any portion thereof) shall mean the date or
dates of the original issue of the Notes represented hereby as specified on the
face hereof, and such Original Issue Date or Dates shall remain the same for all
Notes subsequently issued upon transfer, exchange or substitution of such
original Note (or such subsequently issued Notes) regardless of their dates of
authentication.  The Notes may bear different dates, mature at different times,
bear interest at different dates, be subject to different redemption provisions,
if any, and may otherwise vary, all as provided in the Indenture.

         Interest on this Note will be payable on the Interest Payment Date or
Interest Payment Dates as specified on the face hereof and, in either case, at
Maturity.  Unless otherwise specified on the face hereof, payments on this Note
with respect to any particular Interest Payment Date or the Maturity date will
include interest accrued from and including the applicable Original Issue Date,
or from and including the most recent Interest Payment Date to which interest
has been paid or duly provided for, to but excluding the particular Interest
Payment Date or the Maturity date.  Interest on this Note shall be calculated
for each day during such period by dividing the interest rate applicable to such
day by 360, if the Interest Rate Basis specified on the face hereof is the
Commercial Paper Rate, LIBOR or Prime Rate, or by the actual number of days in
the year, if the Interest Rate Basis specified on the face hereof is the
Treasury Rate.  Unless otherwise provided in an annex attached hereto, the
Trustee, acting in the capacity of Calculation Agent,


                                         C-4



will calculate the Interest Rate on this Note.  Upon the request of any Holder
of this Note, the Trustee shall provide to such Holder the Interest Rate then in
effect and, if then determined, the interest rate that will become effective on
the next Interest Reset Date with respect to this Note.  Each such determination
of an Interest Rate will be final and binding in the absence of manifest error.

         Unless otherwise specified in an annex attached hereto, if this Note
is an Amortizing Note, payments with respect to this Note will be applied first
to interest due and payable hereon and then to the reduction of the unpaid
principal amount hereof.  If this Note is an Amortizing Note, a table setting
forth the schedule of dates and amounts of payments of principal of and interest
on this Note or the formula for the amortization of principal and/or interest is
set forth in an annex attached to this Note.

         All percentages resulting from any calculation with respect to this
Note will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point (with five one-millionths of a percentage point rounded upward)
and all dollar amounts used in or resulting from any such calculation with
respect to this Note will be rounded to the nearest cent (with one-half cent
being rounded upward).

         "Business Day" means, unless otherwise specified on the face hereof,
any Monday, Tuesday, Wednesday, Thursday or Friday that in The City of New York
is not a day on which banking institutions are authorized or obligated by law,
regulation or executive order to close.  If an Interest Payment Date or Maturity
for this Note falls on a day that is not a Business Day, payment of principal,
premium, if any, and interest to be made on such day with respect to this Note
will be made on the next day that is a Business Day with the same force and
effect as if made on the due date, and no additional interest will be payable on
the date of payment for the period from and after the due date as a result of
such delayed payment.

         This Note will be redeemable at the option of the Company prior to its
Stated Maturity only if an Initial Redemption Date is specified on the face
hereof.  If so specified, this Note will be subject to redemption at the option
of the Company on any date on and after such Initial Redemption Date in whole or
from time to time in part in increments of $1,000 or integral multiples thereof,
at the redemption prices specified in an annex attached to this Note, plus
accrued and unpaid interest to but excluding the date of redemption, but


                                         C-5



payments due with respect to this Note prior to the date of redemption will be
payable to the Holder of this Note of record at the close of business on the
relevant Record Date specified on the face hereof, all as provided in the
Indenture.  The Company may exercise such option by causing the Trustee to mail
a notice of such redemption, at least 30 but not more than 60 calendar days
prior to the date of redemption, in accordance with the provisions of the
Indenture.  In the event of redemption of this Note in part only, this Note will
be cancelled and a new Note or Notes representing the unredeemed portion hereof
will be issued in the name of the Holder hereof.  This Note is not subject to a
sinking fund unless otherwise specified in an annex attached hereto.

         If so specified on the face of this Note, (i) this Note shall be
subject to repayment, in whole or in part, prior to Stated Maturity at the
option of the Holder on the Optional Repayment Date or Dates specified on the 
face hereof at the Optional Repayment Price or Prices specified on the face 
hereof, plus accrued and unpaid interest to but excluding the date of payment;
(ii) the Stated Maturity of this Note may be extended at the option of the
Company for one or more Extension Periods of from one to five years, as
specified on the face hereof, up to but not beyond the Final Maturity Date
specified on the face hereof; (iii) the interest rate specified on the face
hereof may be reset by the Company in accordance with a formula or otherwise on
the Optional Interest Reset Date or Dates specified on the face hereof; and/or
(iv) this Note shall be renewable at the option of the Holder, in each case in
accordance with the provisions of the Indenture applicable thereto and/or the 
provisions of an annex attached to this Note.

         Notwithstanding anything herein to the contrary, if this Note is an
Original Issue Discount Note as specified on the face hereof, the amount payable
in the event the principal amount hereof is declared to be due and payable
immediately by reason of an Event of Default or in the event of redemption or
repayment hereof prior to the Stated Maturity hereof, in lieu of the principal
amount due at the Stated Maturity hereof, shall be the Amortized Face Amount of
this Note as of the date of declaration, redemption or repayment, as the case
may be.  The "Amortized Face Amount" of this Note shall be the amount equal to
the principal amount of this Note multiplied by the Issue Price specified on the
face hereof plus (b) the portion of the difference between the dollar amount
thus obtained and the principal amount hereof that has accreted at the Yield to
Maturity specified on the face hereof (computed in accordance with generally
accepted United States bond yield computation principles) to such date of


                                         C-6



declaration, redemption or repayment but in no event shall the Amortized Face
Amount of this Note exceed the principal amount stated on the face hereof.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Noteholders to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not
less than a majority in aggregate principal amount of the Notes then outstanding
that could be affected thereby.  The Indenture also contains provisions
permitting the Holders of not less than a majority in aggregate principal amount
of the Notes then outstanding, on behalf of the Holders of all Notes, to waive
compliance by the Company with certain covenants in the Indenture.  The
Indenture also provides that the Holders of not less than a majority in
aggregate principal amount of the Notes then outstanding may waive certain past
defaults and their consequences on behalf of the Holders of all Notes.  Any such
consent or waiver by the Holder of this Global Note (if not timely revoked in
accordance with the Indenture) shall be conclusive and binding upon such Holder
and upon all future Holders of this Global Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Global Note
or such Note.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Notes will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder, unless such Holder shall have
previously given to the Trustee written notice of a continuing default with
respect to the Notes, the Holders of not less than a majority in aggregate
principal amount of the Notes then outstanding shall have made written request,
and offered reasonable indemnity, to the Trustee to institute such proceeding as
Trustee, and the Trustee shall have failed to institute such proceeding within
60 days; PROVIDED, HOWEVER, that such limitations do not apply to a suit
instituted by the Holder hereof for the enforcement of payment of the principal
of and any premium or interest on this Global Note on or after the respective
due dates expressed herein.

    THIS NOTE IS A GLOBAL NOTE REGISTERED IN THE NAME OF THE DEPOSITARY  OR A
NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR

tender for payment of public and private debts, on the Maturity date specified
above, and to pay interest thereon, in such coin or currency, from and including
the Original Issue Date specified above, or from the most recent Interest
Payment Date specified above to which interest has been paid or duly provided
for, as the case may be.  Interest shall be paid in arrears monthly, quarterly,
semiannually or annually as specified above under Interest Payment Dates, on
each Interest Payment Date in each year and at Maturity, commencing on (a) the
first such Interest Payment Date next succeeding the Original Issue Date
specified above, or (b) if such Original Issue Date is after a Record Date and
prior to the first Interest Payment Date, on the second Interest Payment Date,
at a rate per annum equal to the Initial Interest Rate specified above until the
initial Interest Reset Date specified above, and thereafter at a rate per annum
determined in accordance with the provisions in the Indenture for calculating
the Interest Rate for Notes having the Interest Rate Basis specified above,
until Maturity and the principal hereof is paid or made available for payment.
The interest so payable and punctually paid or duly provided for on any Interest
Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Note is registered at the close of business on the Record Date
specified above next preceding such Interest Payment Date; PROVIDED, HOWEVER
that if the Original issue Date falls between a Record Date and the next
Interest Payment Date, the first payment of interest will be paid on the second
Interest Payment Date subsequent to such Original Issue Date to the Person in
whose name this Note is registered at the close of business on the Record Date
for such second Interest Payment Date; and PROVIDED, FURTHER, that interest
payable on the Maturity date, or, if applicable, upon redemption, shall be
payable to the Person to whom principal shall be payable.  Except as otherwise
provided in the Indenture, any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Record
Date and shall be paid to the Person in whose name this Note is registered at
the close of business on a Record Date for the payment of such defaulted
interest to be fixed by the Company, notice whereof shall be given to
Noteholders not less than fifteen days prior to such Record Date.  Payment of
the principal of and any premium and interest on this Note due at the Maturity
of this Note shall be payable in immediately available funds when due upon
presentation and surrender of such Note at the Corporate Trust Office of the


                                         D-2

Note is presented to the Trustee in time for the Trustee to make such payment in
such funds in accordance with its normal procedures.  Accrued Interest on (and,
if this Note is an Amortizing Note, installments of principal of) this Note
(other than Accrued Interest or such installments payable at Maturity) shall be
paid by a clearinghouse funds check mailed on the Interest Payment Date;
PROVIDED, HOWEVER, that if any Holder of Notes, the aggregate principal amount
of which equals or exceeds $10,000,000, provides a written request to the
Trustee on or before the applicable Record Date for such Interest Payment Date,
Accrued Interest (and such installments of principal) shall be paid by wire
transfer of immediately available funds to a bank within the continental United
States or by direct deposit into the account of such Holder if such account is
maintained with the Trustee.  The Company will pay any administration costs
imposed by banks in connection with making payments by wire transfer, but not
any tax, assessment or governmental charge imposed upon the Holder of this Note.

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET
FORTH IN FULL ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL
PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by 
the Trustee referred to on the reverse hereof, directly or through an 
Authenticating Agent, by manual signature of an authorized signatory, this 
Note shall not be entitled to any benefit under the Indenture or be valid or 
obligatory for any purpose.

executed.

                                         D-3



                              MIDAMERICAN ENERGY COMPANY
                                  MEDIUM-TERM NOTE

         This Note is one of the duly authorized Notes of the Company (herein
called the "Notes"), issued and to be issued under an Indenture dated as of
__________, 1996 (herein called the "Indenture") between the Company and The
First National Bank of Chicago, as Trustee (herein called the "Trustee", which
term includes any successor Trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Noteholders, and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

         Each Note shall be dated the date of its authentication by the
Trustee.  Each Note shall also bear an Original Issue Date which with respect to
this Note (or any portion thereof) shall mean the date of its original issue as
specified on the face hereof, and such Original Issue Date shall remain the same
for all Notes subsequently issued upon transfer, exchange or substitution of
such original Note (or such subsequently issued Notes) regardless of their dates
of authentication.  The Notes may bear different dates, mature at different
times, bear interest at different dates, be subject to different redemption
provisions, if any, and may otherwise vary, all as provided in the Indenture.

         Interest on this Note will be payable on the Interest Payment Date or
Interest Payment Dates as specified on the face hereof and, in either case, at
Maturity.  Unless otherwise specified on the face hereof, payments on this Note
with respect to any particular Interest Payment Date or the Maturity date will
include interest accrued from and including the Original Issue Date, or from and
including the most recent Interest Payment Date to which interest has been paid
or duly provided for, to but excluding such Interest Payment Date or the
Maturity date.  Interest on this Note shall be calculated for each day during
such period by dividing the interest rate applicable to such day by 360, if the
Interest Rate Basis specified on the face hereof is the Commercial Paper Rate,
LIBOR or Prime Rate, or by the actual number of days in the year, if the
Interest Rate Basis specified on the face hereof is the Treasury Rate.  Unless
otherwise provided in an annex attached hereto, the Trustee, acting in the
capacity of Calculation Agent, will calculate the Interest Rate on this Note.
Upon the request of any Holder of


                                         D-4



this Note, the Trustee shall provide to such Holder the Interest Rate then in
effect and, if then determined, the interest rate that will become effective on
the next Interest Reset Date with respect to this Note.  Each such determination
of an Interest Rate will be final and binding in the absence of manifest error.

         Unless otherwise specified in an annex attached hereto, if this Note
is an Amortizing Note, payments with respect to this Note will be applied first
to interest due and payable hereon and then to the reduction of the unpaid
principal amount hereof.  If this Note is an Amortizing Note, a table setting
forth the schedule of dates and amounts of payments of principal of and interest
on this Note or the formula for the amortization of principal and/or interest is
set forth in an annex attached to this Note.

         All percentages resulting from any calculation with respect to this
Note will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point (with five one-millionths of a percentage point rounded upward)
and all dollar amounts used in or resulting from any such calculation with
respect to this Note will be rounded to the nearest cent (with one-half cent
being rounded upward).

         "Business Day" means, unless otherwise specified on the face hereof,
any Monday, Tuesday, Wednesday, Thursday or Friday that in The City of New York
is not a day on which banking institutions are authorized or obligated by law,
regulation or executive order to close.  If an Interest Payment Date or Maturity
for this Note falls on a day that is not a Business Day, payment of principal,
premium, if any, and interest to be made on such day with respect to this Note
will be made on the next day that is a Business Day with the same force and
effect as if made on the due date, and no additional interest will be payable on
the date of payment for the period from and after the due date as a result of
such delayed payment.

         This Note will be redeemable at the option of the Company prior to its
Stated Maturity only if an Initial Redemption Date is specified on the face
hereof.  If so specified, this Note will be subject to redemption at the option
of the Company on any date on and after such Initial Redemption Date in whole or
from time to time in part in increments of $1,000 or integral multiples thereof,
at the redemption prices specified in an annex attached to this Note, plus
accrued and unpaid interest to but excluding the date of redemption, but
payments due with respect to this Note prior to the date of redemption will be
payable to the Holder of this Note of record at the close of business on the
relevant Record Date specified on


                                         D-5



the face hereof, all as provided in the Indenture.  The Company may exercise
such option by causing the Trustee to mail a notice of such redemption, at least
30 but not more than 60 calendar days prior to the date of redemption, in
accordance with the provisions of the Indenture.  In the event of redemption of
this Note in part only, this Note will be cancelled and a new Note or Notes
representing the unredeemed portion hereof will be issued in the name of the
Holder hereof.  This Note is not subject to a sinking fund unless otherwise
specified in an annex attached hereto.

         If so specified on the face of this Note, (i) this Note shall be
subject to repayment, in whole or in part, prior to Stated Maturity at the
option of the Holder on a certain date or dates and at a certain price or
prices, plus accrued and unpaid interest to but excluding the date of payment;
(ii) the Stated Maturity of this Note may be extended at the option of the
Company for one or more Extension Periods of from one to five years, as
specified on the face hereof, up to but not beyond the Final Maturity Date
specified on the face hereof; (iii) the interest rate specified on the face
hereof may be reset by the Company in accordance with a formula or otherwise on
the Optional Interest Reset Date or Dates specified on the face hereof; and/or
(iv) this Note shall be renewable at the option of the Holder, in each case in
accordance with the provisions of the Indenture applicable thereto and/or as
specified in an annex attached to this Note.

         Notwithstanding anything herein to the contrary, if this Note is an
Original Issue Discount Note as specified on the face hereof, the amount payable
in the event the principal amount hereof is declared to be due and payable
immediately by reason of an Event of Default or in the event of redemption or
repayment hereof prior to the Stated Maturity hereof, in lieu of the principal
amount due at the Stated Maturity hereof, shall be the Amortized Face Amount of
this Note as of the date of declaration, redemption or repayment, as the case
may be.  The "Amortized Face Amount" of this Note shall be the amount equal to
the principal amount of this Note multiplied by the Issue Price specified on the
face hereof plus (b) the portion of the difference between the dollar amount
thus obtained and the principal amount hereof that has accreted at the Yield to
Maturity specified on the face hereof (computed in accordance with generally
accepted United States bond yield computation principles) to such date of
declaration, redemption or repayment but in no event shall the Amortized Face
Amount of this Note exceed the principal amount stated on the face hereof.


                                         D-6



         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Noteholders to be affected under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not
less than a majority in aggregate principal amount of the Notes then outstanding
that would be affected thereby.  The Indenture also contains provisions
permitting the Holders of not less than a majority in aggregate principal amount
of the Notes then outstanding, on behalf of the Holders of all Notes, to waive
compliance by the Company with certain covenants in the Indenture.  The
Indenture also provides that the Holders of not less than a majority in
aggregate principal amount of the Notes then outstanding may waive certain past
defaults and their consequences on behalf of the Holders of all Notes.  Any such
consent or waiver by the Holder of this Global Note (if not timely revoked in
accordance with the Indenture) shall be conclusive and binding upon such Holder
and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note or such
Note.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Notes will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder, unless such Holder shall have
previously given to the Trustee written notice of a continuing default with
respect to the Notes, the Holders of not less than a majority in aggregate
principal amount of the Notes then outstanding shall have made written request,
and offered reasonable indemnity, to the Trustee to institute such proceeding as
Trustee, and the Trustee shall have failed to institute such proceeding within
60 days; PROVIDED, HOWEVER, that such limitations do not apply to a suit
instituted by the Holder hereof for the enforcement of payment of the principal
of and any premium or interest on this Note on or after the respective due dates
expressed herein.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the times, places and rates, and in the coin or currency, herein
prescribed.

         The Indenture contains provisions for the satisfaction and discharge
