                                  THE COMPANY
 
GENERAL
 
    MidAmerican Energy was formed on July 1, 1995 through the merger (the
"Merger") of Iowa-Illinois Gas and Electric Company ("Iowa-Illinois"), Midwest
Resources Inc. ("Midwest Resources") and Midwest Power Systems Inc. ("Midwest
Power") with and into MidAmerican Energy. MidAmerican Energy is a combination
electric and natural gas public utility engaged in the generation, transmission,
distribution and sale of electric energy in Illinois, Iowa and South Dakota, and
the purchase, distribution, transportation and sale of natural gas in those
states and in the state of Nebraska. MidAmerican Energy's nonregulated
operations are conducted by its MidAmerican Capital Company ("MidAmerican
Capital") subsidiary; a separate wholly-owned subsidiary, Midwest Capital Group,
Inc. ("Midwest Capital"), functions as a regional business development company
in the utility service territory.
 
    The Company is incorporated in Iowa. Its executive offices are located at
666 Grand Avenue, P.O. Box 657, Des Moines, Iowa 50303-0657 (telephone number
(515) 242-4300).
 
RECENT DEVELOPMENTS
 
    On April 24, 1996, the Company's shareholders approved a proposal to form a
holding company. The holding company will have three wholly-owned subsidiaries
consisting of MidAmerican Energy (utility operations), MidAmerican Capital and
Midwest Capital. The transaction is structured as a share exchange, with each
share of MidAmerican Energy common stock being exchanged for one share of the
holding company common stock. All regulatory approvals have been obtained and it
is management's intention to complete the formation of the holding company on or
about December 1, 1996.
 
    On May 28, 1996, MidAmerican Energy announced the restructuring of portions
of its nonregulated businesses. InterCoast Energy Company ("InterCoast") was
formed as an indirect subsidiary of MidAmerican Energy and a direct subsidiary
of MidAmerican Capital. InterCoast has operations in oil and gas, natural gas
marketing and wholesale electric power marketing and brokering. On October 17,
1996, MidAmerican Capital agreed to sell its subsidiaries which conduct oil and
gas and gas marketing operations to KCS Energy, Inc. for $174 million in cash,
$40 million in short term notes and warrants to acquire 610,000 shares of KCS
Energy, Inc. common stock for $45 per share.

(1) For purposes of computing the ratios of earnings to fixed charges,
    "earnings" consist of net income from continuing operations before interest
    charges and preferred dividend requirements, plus income
 
                                       3

    taxes, plus the estimated interest component of rentals. "Earnings" also
    include allowances for borrowed and other funds used during construction.
    Fixed charges consist of interest charges and the estimated interest
    component of rentals.
 
(2) The supplemental ratios have been calculated including obligations of the
    Company under its long-term power purchase contract with the Nebraska Public
    Power District relating to Cooper Nuclear Station.
 
(3) Reflects the formation of the holding company and the transfer of
    MidAmerican Capital and Midwest Capital to the holding company by
    MidAmerican Energy.
 
                                USE OF PROCEEDS
 
    Except as set forth in the Prospectus Supplement for a specific offering of

                              DESCRIPTION OF NOTES
 
GENERAL
 
    The Notes offered hereby will be issued under the Indenture dated as of
           , 1996, as supplemented from time to time (the "Indenture"), between
the Company and The First National Bank of Chicago, as trustee (the "Trustee").
The Indenture is subject to and governed by the Trust Indenture Act of 1939, as
amended. The summary contained herein of certain provisions of the Notes is
subject to and is qualified in its entirety by reference to the provisions of
the Indenture and the forms of Notes (including the definitions of certain terms
therein), each of which has been filed as an exhibit to the Registration
Statement, to which exhibits reference is hereby made. Certain capitalized terms
used below but not defined herein have the meanings ascribed to them in the
Indenture. Unless otherwise noted, section references below are to the
Indenture.
 
    The Notes are the only securities that may be issued under the Indenture.
The Indenture does not limit the aggregate amount of Notes that may be issued
under the Indenture, but the aggregate initial offering price of the Notes that
may be issued under this Prospectus is limited to $500,000,000, subject to
reduction in the event of sales of certain other securities under the
Registration Statement of which this Prospectus is a part. The Notes will be
denominated in United States dollars, and payments of principal of, premium, if
any, and any interest on the Notes will be made in United States dollars.
Currency amounts in this Prospectus and any Prospectus Supplement are stated in
United States dollars. Unless otherwise specified in the applicable Prospectus
Supplement, the Notes will have the terms described below.
 
    The general provisions of the Indenture do not contain any provisions that
would limit the ability of the Company to incur indebtedness or that would
afford holders of Notes protection in the event of a highly leveraged or similar
transaction involving the Company. However, the general provisions of the
Indenture contain certain restrictions on mortgages and liens. See "Restrictions
on Secured Debt" below. Reference is made to the applicable Prospectus
Supplement for information with respect to any deletions from, modifications of
or additions to the Events of Default or covenants of the Company that are
described below, including any addition of covenants or other provisions
providing event risk or similar protection.
 
    All of the Notes need not be issued at the same time, and may vary as to
interest rate, maturity and other provisions. (Section 2.05) The Notes are
offered on a continuing basis and will mature on a day from nine months to 30
years from their date of issue, as selected by the initial purchaser and agreed
to by the Company, and may be subject to redemption at the option of the Company
or repayment at the option of the Holder prior to Stated Maturity (as defined
below). See "Redemption and Repayment" below.
 
                                       4

    Each Note will be represented by either a global security (a "Book-Entry
Note") registered in the name of a nominee of the Depositary or a certificate
issued in definitive form (a "Certificated Note"), as specified in the
applicable Prospectus Supplement. Beneficial interests in Book-Entry Notes will
be shown on, and transfers thereof will be effected only through, records
maintained by DTC and its participants. Owners of beneficial interests in
Book-Entry Notes will be entitled to physical delivery of Certificated Notes
only under the limited circumstances described herein. See "Book-Entry System"
below. Unless otherwise specified in the applicable Prospectus Supplement, Notes
will be issued in denominations of $1,000 and integral multiples thereof.
(Section 2.04)
 
    Payments of interest and principal (and premium, if any) to Beneficial
Owners (as defined below under "Book-Entry System") of Book-Entry Notes are
expected to be made in accordance with the procedures of the Depositary and its
participants in effect from time to time as described below under "Book-Entry
System."
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
principal of and any premium and accrued interest on all Notes shall be payable
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 Book-Entry Note
pursuant to the terms thereof, the Company will 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
will 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 Book-Entry Note, the
Depositary will surrender, or cause to be surrendered, such Book-Entry Note to
the Trustee, whereupon a new Book-Entry Note will be issued to the Depositary.
 
    (b) With respect to any Note that is not a Book-Entry Note, principal, any
premium and accrued interest due at the Maturity of such Note will be payable in
immediately available funds when due upon presentation and surrender of such
Note at the Corporate Trust Office of the Trustee, currently c/o First Chicago
Trust Company of New York, 14 Wall Street-8th Floor-Window 2, New York, New York
10005; PROVIDED that such 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 Notes, as
defined below under "Amortizing Notes", installments of principal of) any Note
that is not a Book-Entry Note (other than accrued interest or such installments
payable at Maturity) will 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 2.11)
 
    Notwithstanding anything in this Prospectus to the contrary, unless
otherwise specified in the applicable Prospectus Supplement, if a Note is an
Original Issue Discount Note (as defined below under "Original Issue Discount
Notes"), the amount payable on such Note in the event the principal amount
thereof is declared to be due and payable immediately as described below under
"Description of Notes-- Events of Default" or in the event of redemption or
repayment thereof prior to its Stated Maturity, in lieu of the principal amount
due at the Stated Maturity thereof, will be the Amortized Face Amount of such
Note as of the date of declaration, redemption or repayment, as the case may be.
The "Amortized Face Amount" of an Original Issue Discount Note will be the
amount equal to (i) the principal amount of such Note multiplied by the Issue
Price (as defined below) specified in the applicable Prospectus Supplement plus
(ii) the portion of the difference between the dollar amount determined pursuant
to the preceding clause (i) and the principal amount of such Note that has
accreted at the yield to maturity specified in the
 
                                       5
<PAGE>
applicable Prospectus Supplement (computed in accordance with generally accepted
United States bond yield computation principles) to such date of declaration,
redemption or repayment, but in no event will the Amortized Face Amount of an
Original Issue Discount Note exceed the principal amount stated in such Note.
(Section 1.03)
 
    Each Note will bear interest at a fixed rate (a "Fixed Rate Note"), which
may be zero in the case of a Zero Coupon Note, or at a variable rate (a
"Floating Rate Note") determined by reference to the Commercial Paper Rate,
LIBOR, Prime Rate or Treasury Rate or such other interest rate formula (the
"Interest Rate Basis") as may be specified in the applicable Prospectus
Supplement as adjusted by a Spread and/or Spread Multiplier, if any (as defined
herein), applicable to such Notes. The Prospectus Supplement relating to each
Note will describe, among other things, the following items: (i) the price
(expressed as a percentage of the aggregate principal amount thereof) at which
such Note will be issued (the "Issue Price"); (ii) the date on which such Note
will be issued (the "Original Issue Date"); (iii) the date on which such Note
will mature (the "Stated Maturity") and whether the Stated Maturity may be
extended by the Company, and if so, the Extension Periods and the Final Maturity
Date (each as defined below under "Extension of Maturity"); (iv) whether such
Note is a Fixed Rate Note or a Floating Rate Note; (v) if such Note is a Fixed
Rate Note, the rate per annum at which such Note will bear interest, if any, the
Interest Payment Date or Dates, if different from those set forth below under
"Fixed Rate Notes" and whether such rate may be changed by the Company prior to
Stated Maturity; (vi) if such Note is a Floating Rate Note, the Initial Interest
Rate, the Interest Rate Basis, the Interest Reset Dates, the Interest Payment
Dates, the Index Maturity, the Spread, if any, the Spread Multiplier, if any
(all as defined herein), the maximum interest rate, if any, the minimum interest
rate, if any, and any other terms relating to the particular method of
calculating the interest rate for such Note, and whether any such Spread and/or
Spread Multiplier may be changed by the Company prior to Stated Maturity; (vii)
whether such Note is an Original Issue Discount Note, and if so, the yield to
maturity; (viii) whether such Note is an Amortizing Note, and if so, the basis
or formula for the amortization of principal and/or interest and the payment
dates for such periodic principal payments; (ix) the record date or dates for
determining the person entitled to receive payments of interest, principal and
premium, if any (a "Record Date"), if other than as set forth below; (x) whether
such Note may be redeemed at the option of the Company, or repaid at the option
of the Holder, prior to Stated Maturity and, if so, the provisions relating to
such redemption or repayment; (xi) any sinking fund or other mandatory
redemption provisions with respect to such Note; (xii) whether such Note will be
issued initially as a Book-Entry Note or a Certificated Note; and (xiii) any
other terms of such Note not inconsistent with the provisions of the Indenture.
 
    Certificated Notes may be presented for payment and for registration of
transfer or exchange at the Corporate Trust Office of the Trustee, currently c/o
First Chicago Trust Company of New York, 14 Wall Street-8th Floor-Window 2, New
York, New York 10005. (Section 6.02)
 
    All percentages resulting from any calculation with respect to any Notes
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
(e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and
all dollar amounts used in or resulting from such calculation on any Notes will
be rounded to the nearest cent with one-half cent being rounded upward. (Section
2.04)
 
    As used herein, "Business Day" means, unless otherwise specified in the
applicable Prospectus Supplement , 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 and,
with respect to Notes as to which LIBOR (as defined below under "Floating Rate
Notes--LIBOR Notes") is the applicable Interest Rate Basis is also a London
Business Day. As used herein, "London Business Day" means any day on which
dealings in deposits in United States dollars are transacted in the London
interbank market. (Section 1.03)

RESTRICTIONS ON SECURED DEBT
 
    The Notes will constitute unsecured and unsubordinated indebtedness of the
Company, and will rank on a parity with the Company's other unsecured and
unsubordinated indebtedness, but will rank junior to the first mortgage bonds of
the Company ("First Mortgage Bonds") which were issued under the Indenture of
Mortgage and Deed of Trust, dated as of March 1, 1947, from Iowa-Illinois to
Harris Trust and Savings Bank and Lynn Lloyd (C. Potter, successor individual
trustee), as trustees, and indentures supplemental thereto ("Iowa-Illinois Bond
Indenture"), or under the General Mortgage Indenture and Deed of Trust, dated as
of January 1, 1993, between Midwest Power and Morgan Guaranty Trust Company of
New York, trustee (Harris Trust and Savings Bank, successor trustee), and
indentures supplemental thereto ("Midwest Power Bond Indenture").
 
    The Iowa-Illinois Bond Indenture constitutes a first mortgage lien (subject
to permissible encumbrances) on all of the electric generating, transmission and
distribution property, and all of the gas distribution property, which was owned
by Iowa-Illinois at the time of the Merger, and properties thereafter acquired
by the Company which are an integral part of, or essential to the use or
operation of, properties which were subject to the lien of the Iowa-Illinois
Bond Indenture at the time of the Merger. The Midwest Power Bond Indenture
constitutes a first mortgage lien (subject to permissible encumbrances) on all
of the electric generating, transmission and distribution property of the
Company within the State of Iowa which was owned by Midwest Power at the time of
the Merger, and properties thereafter acquired by the Company which are an
integral part of, or essential to the use or operation of, properties which were
subject to the lien of the Midwest Power Bond Indenture at the time of the
Merger. No gas distribution property or property located outside the State of
Iowa which was owned by Midwest Power at the time of the Merger is currently
subject to the lien of the Midwest Power Bond Indenture. However, the Company
has the right to subject such exempted properties to the lien of the Midwest
Power Bond Indenture at any time or times. As a result of the Merger, the
Company has the right to issue First Mortgage Bonds under either the
Iowa-Illinois Bond Indenture or the Midwest Power Bond Indenture, but after the
Company has issued First Mortgage Bonds under one such Bond Indenture, it may
not issue First Mortgage Bonds under the other such Bond Indenture.
 
    The Company has covenanted in the Indenture that while any of the Notes are
outstanding, it will not (i) issue any additional First Mortgage Bonds, or (ii)
subject to the lien of the Iowa-Illinois Bond Indenture or the lien of the
Midwest Power Bond Indenture any property which is exempt from such liens,
unless in each case the Company concurrently issues to the Trustee under the
Indenture, a First Mortgage Bond or Bonds in the same aggregate principal amount
and having the same interest rate or rates, maturity date or dates, redemption
provisions and other terms as the Notes then outstanding and thereby give to the
holders of all outstanding Notes the benefit of the security of such First
Mortgage Bond or Bonds. (Section 4.01) At such time as the Trustee under the
Indenture is the only holder of First Mortgage Bonds outstanding under the
Iowa-Illinois Bond Indenture or the Midwest Power Bond Indenture, the Trustee
will surrender such First Mortgage Bonds to the Company for cancellation and
such Bond Indenture will be discharged and defeased. (Section 4.07).
 
    In addition, the Company has covenanted in the Indenture that neither the
Company nor a Subsidiary will create or assume, except in favor of the Company
or a Wholly-Owned Subsidiary (as defined below under "Certain Definitions"), any
mortgage, pledge, or other lien or encumbrance upon any Principal Facility (as
defined below under "Certain Definitions") or any stock of any Subsidiary or
indebtedness of any Subsidiary to the Company or any other Subsidiary whether
now owned or hereafter acquired without equally and ratably securing the
outstanding Notes. This limitation will not apply to the lien of the Iowa-
Illinois Bond Indenture, the lien of the Midwest Power Bond Indenture or certain
permitted encumbrances described in the Indenture, including (a) purchase money
mortgages entered into within specified time limits; (b) liens extending,
renewing or refunding any liens permitted by clause (a) of this covenant; (c)
liens existing on acquired property; (d) certain tax, materialmen's, mechanics'
and judgment liens, certain liens arising by operation of law and certain other
similar liens; (e) certain mortgages, pledges, liens
 
                                       7
<PAGE>
or encumbrances in favor of any state or local government or governmental agency
in connection with certain tax-exempt financings; (f) liens to secure the cost
of construction or improvement of any property entered into within specified
time limits; and (g) mortgages, pledges, liens and encumbrances not otherwise
permitted if the sum of the indebtedness thereby secured does not exceed the
greater of $100,000,000 or 10% of Common Shareholders' Equity (as defined below
under "Certain Definitions"). (Section 6.06)
 
INTEREST AND INTEREST RATES
 
    Unless otherwise specified in the applicable Prospectus Supplement, each
Note (other than a Zero Coupon Note), will bear interest from and including its
Original Issue Date or from and including the most recent Interest Payment Date
to which interest on such Note has been paid or duly provided for at a fixed
rate per annum or at a rate per annum determined pursuant to an Interest Rate
Basis, stated therein and in the applicable Prospectus Supplement, that may be
adjusted by a Spread and/or Spread Multiplier, until Maturity and the principal
thereof is paid or made available for payment. Unless otherwise specified in the
applicable Prospectus Supplement, interest will be payable on each Interest
Payment Date and at Maturity. "Maturity" means the date on which the principal
of a Note or an installment of principal becomes due and payable in accordance
with its terms and the terms of the Indenture, whether at Stated Maturity, upon
acceleration, redemption, repayment or otherwise. Interest (other than defaulted
interest which may be paid to the Holder on a special record date) will be
payable to the Holder at the close of business on the Record Date next preceding
an Interest Payment Date; provided, however, that the first payment of interest
on any Note originally issued between a Record Date and the next Interest
Payment Date will be made on the Interest Payment Date following the next
succeeding Record Date to the Holder on such next succeeding Record Date and
interest payable on the Maturity date, including, if applicable, upon
redemption, shall be payable to the person to whom principal is payable.
 
    Interest rates, interest rate formulae and other variable terms of the Notes
are subject to change by the Company from time to time, but no such change will
affect any Note already issued or as to which an offer to purchase has been
accepted by the Company. Unless otherwise specified in the applicable Prospectus
Supplement, the Interest Payment Dates and the Record Dates for Fixed Rate Notes
will be as described below under "Fixed Rate Notes." The Interest Payment Dates
for Floating Rate Notes will be as specified in the applicable Prospectus
Supplement, and unless otherwise specified in the applicable Prospectus
Supplement, each Record Date for a Floating Rate Note will be the fifteenth day
(whether or not a Business Day) preceding each Interest Payment Date.
 
    Each Note (other than a Zero Coupon Note) will bear interest at either (a) a
fixed rate or (b) a floating rate determined by reference to an Interest Rate
Basis which may be adjusted by a Spread and/or Spread Multiplier; provided that
the interest rate in effect for the ten days immediately prior to Stated
Maturity will be the interest rate in effect on the tenth day preceding such
Stated Maturity. Any Floating Rate Note may also have either or both of the
following: (i) a maximum interest rate, or ceiling, on the rate of interest
which may accrue during any interest period, and (ii) a minimum interest rate,
or floor, on the rate of interest which may accrue during any interest period.
The applicable Prospectus Supplement relating to each Note will designate either
a fixed rate of interest per annum on the applicable Fixed Rate Note or one or
more of the following Interest Rate Bases as applicable to the relevant Floating
Rate Note: (a) the Commercial Paper Rate, in which case such Note will be a
"Commercial Paper Rate Note," (b) LIBOR, in which case such Note will be a
"LIBOR Note," (c) the Prime Rate, in which case such Note will be a "Prime Rate
Note," (d) the Treasury Rate, in which case such Note will be a "Treasury Rate
Note," or (e) such other Interest Rate Basis or formula as may be specified in
such Prospectus Supplement.
 
    Notwithstanding the determination of the interest rate as provided below,
the interest rate on the Notes for any interest period shall not be greater than
the maximum interest rate, if any, or less than the minimum interest rate, if
any, specified in the applicable Prospectus Supplement. The interest rate on the
 
                                       8
<PAGE>
Notes will in no event be higher than the maximum rate permitted by New York or
other applicable law, as the same may be modified by United States federal law
of general application. Under present New York law, the maximum rate of interest
is 25% per annum on a simple interest basis. This limit may not apply to Notes
in which $2,500,000 or more has been invested.
 
FIXED RATE NOTES
 
    Unless otherwise specified in the applicable Prospectus Supplement, each
Fixed Rate Note (other than a Zero Coupon Note) will accrue interest from and
including its Original Issue Date at the annual rate stated on the face thereof,
as specified in the applicable Prospectus Supplement. Unless otherwise specified
in the applicable Prospectus Supplement, payments of interest on any Fixed Rate
Note with respect to any Interest Payment Date or Maturity 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 Maturity. Fixed
Rate Notes may bear one or more annual rates of interest during the periods or
under the circumstances specified therein and in the applicable Prospectus
Supplement. Unless otherwise specified in the applicable Prospectus Supplement,
interest on Fixed Rate Notes will be computed and paid on the basis of a 360-day
year of twelve 30-day months.
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Interest Payment Dates for Fixed Rate Notes, including Fixed Rate Amortizing
Notes, will be semi-annually on each January 15 and July 15 and the Record Dates
will be each January 1 and July 1 (whether or not a Business Day) and the Stated
Maturity. In the case of Fixed Rate Amortizing Notes, Interest Payment Dates may
be quarterly on each January 15, April 15, July 15 and October 15 if specified
in the applicable Prospectus Supplement, and the Record Dates will be each
January 1, April 1, July 1 and October 1 (whether or not a Business Day) next
preceding each such Interest Payment Date. If the Interest Payment Date or
Maturity for any Fixed Rate Note is not a Business Day, all payments to be made
on such day with respect to such 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.
 
FLOATING RATE NOTES
 
    The interest rate on each Floating Rate Note will be equal to the interest
rate calculated by reference to the specified Interest Rate Basis (i) plus or
minus the Spread, if any, and/or (ii) multiplied by the Spread Multiplier, if
any. The "Spread" is the number of basis points (one basis point equals
one-hundredth of a percentage point) specified in the applicable Prospectus
Supplement as being applicable to such Note, and the "Spread Multiplier" is the
percentage of the Interest Rate Basis (adjusted for any Spread) specified in the
applicable Prospectus Supplement as being applicable to such Note. The
applicable Prospectus Supplement will specify the Interest Rate Basis and the
Spread and/or Spread Multiplier, if any, and the maximum or minimum interest
rate, if any, applicable to each Floating Rate Note. In addition, such
Prospectus Supplement will contain particulars as to the Calculation Agent
(unless otherwise specified in the applicable Prospectus Supplement, The First
National Bank of Chicago (in such capacity, the "Calculation Agent")), Index
Maturity, Original Issue Date, the interest rate in effect for the period from
the Original Issue Date to the first Interest Reset Date specified in the
applicable Prospectus Supplement (the "Initial Interest Rate"), Interest
Determination Dates, Interest Payment Dates, Record Dates, and Interest Reset
Dates with respect to such Note.
 
    Except as provided below or in the applicable Prospectus Supplement, the
Interest Payment Dates for Floating Rate Notes, including Floating Rate
Amortizing Notes, will be (i) in the case of Floating Rate Notes that reset
daily, weekly or monthly, the third Wednesday of each month or the third
Wednesday of March, June, September and December of each year, as specified on
the face thereof and in the applicable Prospectus Supplement; (ii) in the case
of Floating Rate Notes that reset quarterly, the third Wednesday of
 
                                       9
<PAGE>
March, June, September and December of each year as specified on the face
thereof and in the applicable Prospectus Supplement; (iii) in the case of
Floating Rate Notes that reset semiannually, the third Wednesday of each of two
months of each year, as specified on the face thereof and in the applicable
Prospectus Supplement; and (iv) in the case of Floating Rate Notes that reset
annually, the third Wednesday of one month of each year, as specified on the
face thereof and in the applicable Prospectus Supplement and, in each case, at
Maturity. If any Interest Payment Date, other than Maturity, for any Floating
Rate Note is not a Business Day for such Floating Rate Note, such Interest
Payment Date will be postponed to the next day that is a Business Day for such
Floating Rate Note, except that, in the case of a LIBOR Note, if such Business
Day for such Floating Rate Note is in the next succeeding calendar month, such
Interest Payment Date will be the immediately preceding London Business Day. If
the Maturity for any Floating Rate Note falls on a day that is not a Business
Day, all payments to be made on such day with respect to such 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.
 
    The rate of interest on each Floating Rate Note will be reset daily, weekly,
monthly, quarterly, semiannually or annually (such period being the "Interest
Reset Period" for such Note, and the first day of each Interest Reset Period
being an "Interest Reset Date"), as specified in the applicable Prospectus
Supplement. Unless otherwise specified in the applicable Prospectus Supplement,
the Interest Reset Date will be, in the case of Floating Rate Notes which reset
daily, each Business Day for such Floating Rate Note; in the case of Floating
Rate Notes (other than Treasury Rate Notes) which reset weekly, the Wednesday of
each week; in the case of Treasury Rate Notes which reset weekly, the Tuesday of
each week, except as provided below; in the case of Floating Rate Notes which
reset monthly, the third Wednesday of each month; in the case of Floating Rate
Notes which reset quarterly, the third Wednesday of each March, June, September
and December; in the case of Floating Rate Notes which reset semiannually, the
third Wednesday of each of two months of each year, as specified in the
applicable Prospectus Supplement; and in the case of Floating Rate Notes which
reset annually, the third Wednesday of one month of each year, as specified in
the applicable Prospectus Supplement; provided, however, that the interest rate
in effect from the Original Issue Date to but excluding the first Interest Reset
Date with respect to a Floating Rate Note will be the Initial Interest Rate (as
specified in the applicable Prospectus Supplement). If any Interest Reset Date
for any Floating Rate Note is not a Business Day for such Floating Rate Note,
such Interest Reset Date will be postponed to the next day that is a Business
Day for such Floating Rate Note, except that in the case of a LIBOR Note, if
such Business Day is in the next succeeding calendar month, such Interest Reset
Date will be the immediately preceding London Business Day. Each adjusted rate
will be applicable on and after the Interest Reset Date to which it relates to
but excluding the next succeeding Interest Reset Date or until Maturity.
 
    The interest rate for each Interest Reset Period will be the rate determined
by the Calculation Agent on the Calculation Date (as defined below) pertaining
to the Interest Determination Date pertaining to the Interest Reset Date for
such Interest Reset Period. Unless otherwise specified in the applicable
Prospectus Supplement, the "Interest Determination Date" pertaining to an
Interest Reset Date for (a) a Commercial Paper Rate Note (the "Commercial Paper
Interest Determination Date") or (b) a Prime Rate Note (the "Prime Interest
Determination Date") will be the second Business Day immediately preceding such
Interest Reset Date. Unless otherwise specified in the applicable Prospectus
Supplement, the Interest Determination Date pertaining to an Interest Reset Date
for a LIBOR Note (the "LIBOR Interest Determination Date") will be the second
London Business Day immediately preceding such Interest Reset Date. Unless
otherwise specified in the applicable Prospectus Supplement, the Interest
Determination Date pertaining to an Interest Reset Date for a Treasury Rate Note
(the "Treasury Interest Determination Date") will be the day of the week in
which such Interest Reset Date falls on which Treasury bills would normally be
auctioned. Treasury bills are usually sold at auction on Monday of each week,
unless that day is a legal holiday, in which case the auction is usually held on
the following Tuesday, except that such auction may be held on the preceding
Friday. If an auction is so held on the preceding Friday, such Friday will be
 
                                       10
<PAGE>
the Treasury Interest Determination Date pertaining to the Interest Reset Period
commencing in the next succeeding week. If an auction date falls on any Interest
Reset Date for a Treasury Rate Note, then such Interest Reset Date will instead
be the first Business Day immediately following such auction date. Unless
otherwise specified in the applicable Prospectus Supplement, the "Calculation
Date" pertaining to any Interest Determination Date will be the earlier of (i)
the tenth calendar day after the Interest Determination Date or, if such day is
not a Business Day, the next day that is a Business Day, or (ii) the Business
Day immediately preceding the applicable Interest Payment Date or Maturity, as
the case may be.
 
    "Index Maturity" means, with respect to a Floating Rate Note, the period to
Stated Maturity of the instrument or obligation on which the interest rate
formula of such Floating Rate Note is calculated, as specified in the applicable
Prospectus Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement, each
Floating Rate Note will accrue interest from and including its Original Issue
Date at the rate determined as provided in such Note and as specified in the
applicable Prospectus Supplement. Unless otherwise specified in the applicable
Prospectus Supplement, payments of interest on any Floating Rate Note with
respect to any Interest Payment 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 Interest Payment Date or Maturity. With respect to Floating
Rate Notes, accrued interest is calculated by multiplying the face amount of a
Note by an accrued interest factor. This accrued interest factor is computed by
adding the interest factors calculated for each day from and including the
Original Issue Date, or from and including the last date to which interest has
been paid or duly provided for, to but excluding the date for which accrued
interest is being calculated. The interest factor for each such day (unless
otherwise specified) is computed by dividing the interest rate applicable to
such day by 360, in the case of Commercial Paper Rate Notes, LIBOR Notes and
Prime Rate Notes or by the actual number of days in the year, in the case of
Treasury Rate Notes.
 
    The Calculation Agent will calculate the interest rate on the Floating Rate
Notes, as provided below. The Trustee will, upon the request of the Holder of
any Floating Rate Note, provide the interest rate then in effect and, if then
determined, the interest rate which will become effective as a result of a
determination made with respect to the most recent Interest Determination Date
(defined below) with respect to such Note. For purposes of calculating the rate
of interest payable on Floating Rate Notes, the Company has entered into or will
enter into an agreement with the Calculation Agent. The Calculation Agent's
determination of any interest rate shall be final and binding in the absence of
manifest error.
 
  COMMERCIAL PAPER RATE NOTES
 
    Each Commercial Paper Rate Note will bear interest at the interest rate
(calculated with reference to the Commercial Paper Rate and the Spread and/or
Spread Multiplier, if any) specified in the Commercial Paper Rate Note and in
the applicable Prospectus Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement,
"Commercial Paper Rate" means, with respect to any Commercial Paper Interest
Determination Date, the Money Market Yield (calculated as described below) of
the rate on such date for commercial paper having the Index Maturity specified
in the applicable Prospectus Supplement as published by the Board of Governors
of the Federal Reserve System in "Statistical Release H.15(519), Selected
Interest Rates" or any successor publication of the Board of Governors
("H.15(519)") under the heading "Commercial Paper." In the event that such rate
is not published prior to 9:00 A.M., New York City time, on the Calculation Date
pertaining to such Commercial Paper Interest Determination Date, then the
Commercial Paper Rate with respect to such Commercial Paper Interest
Determination Date will be the Money Market Yield of the rate on such Commercial
Paper Interest Determination Date for commercial paper having the Index Maturity
specified in the applicable Prospectus Supplement as published by the Federal
Reserve Bank of New York in its daily statistical release "Composite 3:30 P.M.
Quotations for U.S. Government Securities" or any successor
 
                                       11
<PAGE>
publication ("Composite Quotations") under the heading "Commercial Paper." If by
3:00 P.M., New York City time, on such Calculation Date such rate is not
published in either H.15(519) or Composite Quotations, then the Commercial Paper
Rate with respect to such Commercial Paper Interest Determination Date will be
calculated by the Calculation Agent and will be the Money Market Yield of the
arithmetic mean of the offered rates (quoted on a bank discount basis) as of
11:00 A.M., New York City time, on such Commercial Paper Interest Determination
Date of three leading dealers of commercial paper in The City of New York
selected by the Calculation Agent for commercial paper having the Index Maturity
specified in the applicable Prospectus Supplement placed for an industrial
issuer whose bond rating is "AA," or the equivalent, from a nationally
recognized securities rating agency; provided, however, that if the dealers
selected as aforesaid by the Calculation Agent are not quoting as mentioned in
this sentence, the Commercial Paper Rate with respect to such Commercial Paper
Interest Determination Date will be the Commercial Paper Rate in effect
immediately prior to such Commercial Paper Interest Determination Date.
 
    "Money Market Yield" will be a yield (expressed as a percentage rounded, if
necessary, to the nearest one hundred-thousandth of a percent) calculated in
accordance with the following formula:
 
<TABLE>
<S>                      <C>              <C>
                             D x 360
Money Market Yield  =    --------------       x 100
                          360 - (D x M)
</TABLE>
 
where "D" refers to the per annum rate for commercial paper, quoted on a bank
discount basis and expressed as a decimal; and "M" refers to the actual number
of days in the period for which accrued interest is being calculated.
 
  LIBOR NOTES
 
    Each LIBOR Note will bear interest at the interest rate (calculated with
reference to LIBOR and the Spread and/or Spread Multiplier, if any) specified in
the LIBOR Note and in the applicable Prospectus Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement, "LIBOR"
means, with respect to any LIBOR Interest Determination Date, the rate
determined by the Calculation Agent in accordance with the following provisions:
 
    (i) With respect to any LIBOR Interest Determination Date, LIBOR will be
either: (a) if "LIBOR Reuters" is specified in the Note and the applicable
Prospectus Supplement, the arithmetic mean of the offered rates (unless the
specified Designated LIBOR Page (as defined below) by its terms provides only
for a single rate, in which case such single rate will be used) for deposits in
United States dollars having the Index Maturity specified in the Note and the
applicable Prospectus Supplement, commencing on the second London Business Day
immediately following such LIBOR Interest Determination Date, which appear on
the Designated LIBOR Page specified in the Note and the applicable Prospectus
Supplement as of 11:00 A.M., London time, on that LIBOR Interest Determination
Date, if at least two such offered rates appear (unless, as aforesaid, only a
single rate is required) on such Designated LIBOR Page, or (b) if "LIBOR
Telerate" is specified in the Note and the applicable Prospectus Supplement, the
rate for deposits in United States dollars having the Index Maturity specified
in the Note and the applicable Prospectus Supplement, commencing on the second
London Business Day immediately following such LIBOR Interest Determination
Date, which appears on the Designated LIBOR Page specified in the Note and the
applicable Prospectus Supplement as of 11:00 A.M., London time, on that LIBOR
Interest Determination Date. Notwithstanding the foregoing, if fewer than two
offered rates appear on the Designated LIBOR Page with respect to LIBOR Reuters
(unless the specified Designated LIBOR Page by its terms provides only for a
single rate, in which case such single rate will be used), or if no rate appears
on the Designated LIBOR Page with respect to LIBOR Telerate, whichever may be
applicable, LIBOR with respect to such
 
                                       12
<PAGE>
LIBOR Interest Determination Date will be determined as if the parties had
specified the rate described in clause (ii) below.
 
    (ii) With respect to any LIBOR Interest Determination Date on which fewer
than two offered rates appear on the Designated LIBOR Page with respect to LIBOR
Reuters (unless the specified Designated LIBOR Page by its terms provides only
for a single rate, in which case such single rate will be used), or if no rate
appears on the Designated LIBOR Page with respect to LIBOR Telerate, as the case
may be, the Calculation Agent will request the principal London office of each
of four major banks in the London interbank market selected by the Calculation
Agent to provide the Calculation Agent with its offered rate quotation for
deposits in United States dollars for the period of the Index Maturity specified
in the Note and the applicable Prospectus Supplement, commencing on the second
London Business Day immediately following such LIBOR Interest Determination
Date, to prime banks in the London interbank market as of 11:00 A.M., London
time, on such LIBOR Interest Determination Date and in a principal amount that
is representative for a single transaction in United States dollars in such
market at such time. If at least two such quotations are provided, LIBOR with
respect to such LIBOR Interest Determination Date will be calculated by the
Calculation Agent and will be the arithmetic mean of such quotations. If fewer
than two quotations are provided, LIBOR with respect to such LIBOR Interest
Determination Date will be the arithmetic mean of the rates quoted as of 11:00
A.M. New York City Time, on such LIBOR Interest Determination Date by three
major banks in The City of New York selected by the Calculation Agent for loans
in United States Dollars to leading European banks, commencing on the second
London Business Day immediately following such LIBOR Interest Determination Date
having the Index Maturity specified in the Note and the applicable Prospectus
Supplement in a principal amount that is representative for a single transaction
in such United States dollars in such market at such time; PROVIDED, HOWEVER,
that if the banks so selected by the Calculation Agent are not quoting as
mentioned in this sentence, LIBOR with respect to such LIBOR Interest
Determination Date will be LIBOR in effect immediately prior to such LIBOR
Interest Determination Date.
 
    "Designated LIBOR Page" means either (a) the display on the Reuters Monitor
Money Rates Service for the purpose of displaying the London interbank rates of
major banks for United States Dollars (if "LIBOR Reuters" is specified in the
Note and the applicable Prospectus Supplement), or (b) the display on the Dow
Jones Telerate Service for the purpose of displaying the London interbank rates
of major banks for United States dollars (if "LIBOR Telerate" is specified in
the Note and the applicable Prospectus Supplement). If neither LIBOR Reuters nor
LIBOR Telerate is specified in the Note and the applicable Prospectus
Supplement, LIBOR for United States dollars will be determined as if LIBOR
Telerate (and page 3750) had been chosen.
 
  PRIME RATE NOTES
 
    Each Prime Rate Note will bear interest at the interest rate (calculated
with reference to the Prime Rate and the Spread and/or Spread Multiplier, if
any) specified in the Prime Rate Note and in the applicable Prospectus
Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement, "Prime
Rate" means, with respect to any Prime Interest Determination Date, the rate on
such date as published in H.15(519) under the heading "Bank Prime Loan." In the
event that such rate is not published prior to 9:00 A.M., New York City time, on
the Calculation Date pertaining to such Prime Interest Determination Date, then
the Prime Rate with respect to such Prime Interest Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean of the rates
of interest publicly announced by each bank that appears on the Reuters Screen
USPRIME1 as such bank's prime rate or base lending rate as in effect with
respect to such Prime Interest Determination Date. If fewer than four such rates
appear on the Reuters Screen USPRIME1 with respect to such Prime Interest
Determination Date, the Prime Rate with respect to such Prime Interest
Determination Date will be calculated by the Calculation Agent and will be the
arithmetic mean of the prime rates quoted on the basis of the actual number of
days in the year divided by 360 as of
 
                                       13
<PAGE>
the close of business on such Prime Interest Determination Date by at least two
of the three major money center banks in The City of New York selected by the
Calculation Agent. If fewer than two quotations are provided, the Prime Rate
with respect to such Prime Interest Determination Date will be determined on the
basis of the rates furnished in The City of New York by the appropriate number
of substitute banks or trust companies organized and doing business under the
laws of the United States, or any state thereof, having total equity capital of
at least $500,000,000 and being subject to supervision or examination by federal
or state authority, selected by the Calculation Agent to provide such rate or
rates; PROVIDED, HOWEVER, that if the appropriate number of substitute banks or
trust companies selected as aforesaid are not quoting as mentioned in this
sentence, the Prime Rate with respect to such Prime Interest Determination Date
will be the Prime Rate in effect immediately prior to such Prime Interest
Determination Date.
 
    "Reuters Screen USPRIME1" means the display designated as page "USPRIME1" on
the Reuters Monitor Money Rate Service (or such other page which may replace the
USPRIME1 page on the service for the purpose of displaying the prime rate or
base lending rate of major banks).
 
  TREASURY RATE NOTES
 
    Each Treasury Rate Note will bear interest at the interest rate (calculated
with reference to the Treasury Rate and the Spread and/or Spread Multiplier, if
any) specified in the Treasury Rate Note and in the applicable Prospectus
Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement,
"Treasury Rate" means, with respect to any Treasury Interest Determination Date,
the rate resulting from the most recent auction of direct obligations of the
United States ("Treasury bills") having the Index Maturity specified in the
applicable Prospectus Supplement, as such rate is published in H.15(519) under
the heading, "Treasury bills--auction average (investment)" or, if not so
published by 3:00 P.M., New York City time, on the Calculation Date pertaining
to such Treasury Interest Determination Date, the average auction rate on such
Treasury Interest Determination Date (expressed as a bond equivalent, on the
basis of a year of 365 or 366 days, as applicable, and applied on a daily basis)
as otherwise announced by the United States Department of the Treasury. In the
event that the results of the auction of Treasury Bills having the specified
Index Maturity are not reported as provided above by 3:00 P.M., New York City
time, on the Calculation Date pertaining to such Treasury Interest Determination
Date, or if no such auction is held in a particular week, then the Treasury Rate
with respect to such Treasury Interest Determination Date will be calculated by
the Calculation Agent and will be a yield to maturity (expressed as a bond
equivalent, on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) of the arithmetic mean of the secondary market bid
rates, as of approximately 3:30 P.M., New York City time, on such Treasury
Interest Determination Date, of three leading primary U.S. government securities
dealers selected by the Calculation Agent for the issue of Treasury bills with a
remaining maturity closest to the Index Maturity specified in the applicable
Prospectus Supplement; PROVIDED, HOWEVER, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as mentioned in this
sentence, the Treasury Rate with respect to such Treasury Interest Determination
Date will be the Treasury Rate in effect immediately prior to such Treasury
Interest Determination Date.
 
ORIGINAL ISSUE DISCOUNT NOTES
 
    The Company may from time to time offer Original Issue Discount Notes. The
Prospectus Supplement applicable to certain Original Issue Discount Notes may
provide that Holders of such Notes will not receive periodic payments of
interest. For purposes of determining whether Holders of the requisite principal
amount of Notes outstanding under the Indenture have made a demand or given a
notice or waiver or taken any other action, the outstanding principal amount of
Original Issue Discount Notes shall be deemed to be the amount of the principal
that would be due and payable upon declaration of acceleration of the Stated
Maturity thereof as of the date of such determination. See "General."
 
                                       14
<PAGE>
    "Original Issue Discount Note" means (i) a Note that has a "stated
redemption price at maturity" that exceeds its "issue price" (each as defined
for United States federal income tax purposes) by at least 0.25% of its stated
redemption price at maturity multiplied by the number of complete years from the
Original Issue Date to the Stated Maturity for such Note (or, in the case of a
Note that provides for payment of any amount other than the "qualified stated
interest" (as so defined) prior to maturity, the weighted average maturity of
the Note) and (ii) any other Note designated by the Company as issued with
original issue discount for United States federal income tax purposes.
 
AMORTIZING NOTES
 
    The Company may from time to time offer Notes for which payments of
principal and interest are made in installments over the life of the Note
("Amortizing Notes"). Interest on each Amortizing Note will be computed as
specified in the applicable Prospectus Supplement. Unless otherwise specified in
the applicable Prospectus Supplement, payments with respect to an Amortizing
Note will be applied first to interest due and payable thereon and then to the
reduction of the unpaid principal amount thereof. A table setting forth
repayment information with respect to each Amortizing Note will be attached to
such Note and to the applicable Prospectus Supplement and will be available,
upon request, to subsequent Holders.
 
RESET NOTES
 
    The Prospectus Supplement relating to each Note will indicate whether the
Company has the option with respect to such Note to reset the interest rate, in
the case of a Fixed Rate Note, or to reset the Spread and/or Spread Multiplier,
in the case of a Floating Rate Note (in each case, a "Reset Note"), and, if so,
(i) the date or dates on which such interest rate or such Spread and/or Spread
Multiplier, as the case may be, may be reset (each an "Optional Interest Reset
Date") and (ii) the formula, if any, for such resetting.
 
    The Company may exercise such option with respect to a Note 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 will 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 notice (the "Reset Notice") indicating (i) that the
Company has elected to reset 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, (ii) such new interest rate or such new Spread and/or Spread Multiplier,
as the case may be, and (iii) the provisions, if any, for redemption of such
Note during the period from such Optional Interest Reset Date to the next
Optional Interest Reset Date or, if there is no such next Optional Interest
Reset Date, to the Stated Maturity of such Note (each such period a "Subsequent
Interest Period"), including the date or dates on which or the period or periods
during which and the price or prices at which such redemption may occur during
such Subsequent Interest Period.
 
    Notwithstanding the foregoing, 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 the 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. Such notice will be irrevocable. All Notes with respect to 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
 
                                       15
<PAGE>
rate, in the case of a Floating Rate Note, whether or not tendered for repayment
as provided in the next paragraph.
 
    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 will 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 below under "Redemption and Repayment" 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 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.
 
EXTENSION OF MATURITY
 
    The Prospectus Supplement relating to each Note will indicate whether the
Company has the option to extend the Stated Maturity of such Note for one or
more periods of from one to five whole years (each an "Extension Period") up to
but not beyond the date (the "Final Maturity Date") specified in such Prospectus
Supplement.
 
    The Company may exercise such option with respect to a Note by notifying the
Trustee of such exercise at least 45 but not more than 60 calendar days prior to
the Stated Maturity of such Note (including, if such Stated Maturity has
previously been extended, the Stated Maturity as previously extended) in effect
prior to the exercise of such option (the "Pre-Exercise Stated Maturity Date").
If the Company so notifies the Trustee of such exercise, the Trustee will send
not later than 40 calendar days prior to the Pre-Exercise Stated Maturity Date,
by telegram, telex, facsimile transmission, hand delivery or letter (first
class, postage prepaid) to the Holder of such Note a notice (the "Extension
Notice") relating to such Extension Period, indicating (i) that the Company has
elected to extend the Stated Maturity of such Note, (ii) the new Stated
Maturity, (iii) in the case of a Fixed Rate Note, the interest rate applicable
to such Extension Period or, in the case of a Floating Rate Note, the Spread
and/or Spread Multiplier applicable to the Extension Period, and (iv) the
provisions, if any, for redemption of such Note during the Extension Period,
including the date or dates on which or the period or periods during which and
the price or prices at which such redemption may occur during the Extension
Period. 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 as described in the next two
paragraphs, such Note will have the same terms as prior to the sending of such
Extension Notice.
 
    Notwithstanding the foregoing, not later than 20 calendar days prior to the
Pre-Exercise Stated Maturity 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 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. 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 the next paragraph.
 
                                       16
<PAGE>
    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 will have the option to elect repayment of
such Note, in whole but not in part, by the Company on the Pre-Exercise Stated
Maturity Date (including 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 Original
Stated Maturity Date, the Holder thereof must follow the procedures set forth
below under "Redemption and Repayment" 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 Original 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 Original Stated Maturity Date.
 
RENEWABLE NOTES
 
    The applicable Prospectus Supplement will indicate whether a Note (other
than an Amortizing Note) will mature at its Pre-Exercise Stated Maturity Date
unless the term of all or any portion of any such Note is renewed by the Holder
in accordance with the procedures described in such Prospectus Supplement.
 
COMBINATION OF PROVISIONS
 
    If so specified in the applicable Prospectus Supplement, any Note may be
subject to all of the provisions, or any combination of the provisions,
described above under "Reset Notes," "Extension of Maturity" and "Renewable
Notes."
 
REDEMPTION AND REPAYMENT
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Notes will not be subject to any sinking fund. The Notes will be redeemable at
the option of the Company prior to the Stated Maturity thereof only if an
Initial Redemption Date is specified in the applicable Prospectus Supplement
("Initial Redemption Date"). If so specified, the Notes will be subject to
redemption at the option of the Company on the date or dates and at the prices
specified in such Prospectus Supplement. The selection of Notes or portions
thereof to be redeemed prior to their Stated Maturity shall be in the sole
discretion of the Company. 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.
The Company may exercise any 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 a Note in part only, such Note will be cancelled and a
new Note or Notes representing the unredeemed portion thereof will be issued in
the name of the Holder thereof. (Section 3.02)
 
    Unless otherwise specified in the applicable Prospectus Supplement, a Note
will not be repayable prior to Stated Maturity at the option of the Holder. If
so specified, a Note will 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 Prospectus Supplement, plus accrued and unpaid
interest to but excluding the date of repayment.
 
    In order for a Note that is repayable at the option of the Holder to be
repaid prior to Stated Maturity, the Trustee must receive 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" set forth in 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 States setting forth the name of the Holder of the
Note, the principal
 
                                       17
<PAGE>
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" set forth in the Note duly completed will be received by the Trustee
not later than five Business Days after the date of such telegram, telex,
facsimile transmission, hand delivery or letter and such Note and form duly
completed are received by the Trustee by such fifth Business Day. Exercise of
the repayment option by the Holder of a Note will be irrevocable, except that a
Holder who has tendered a Note for repayment may revoke such tender for
repayment by written notice to the Paying Agent received prior to 5:00 P.M., New
York City time, on the tenth calendar day prior to the repayment date. 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 will be issued in the name of the
Holder thereof.
 
    While any Book-Entry Note is represented by one or more global Notes (each,
a "Global Note") held by or on behalf of the Depositary, and registered in the
name of the Depositary or its nominee, any such option for repayment may be
exercised by the applicable Participant (as defined below under "Book-Entry
System") that has an account with the Depositary, on behalf of a Beneficial
Owner of the Global Note or Notes representing such Book-Entry 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 will 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 Participants on behalf of Beneficial Owners of the
Global Note or Notes representing such Book-Entry Notes to exercise their option
to have such Book-Entry Notes repaid must be received by the Trustee by 5:00
P.M., New York City time, on the last day for giving such notice. In order to
ensure that a notice is received by the Trustee on a particular day, the
Beneficial Owner of the Global Note or Notes representing such Book-Entry Notes
must so direct the applicable Participant before such Participant's deadline for
accepting instructions for that day. Different firms may have different
deadlines for accepting instructions from their customers. Accordingly,
Beneficial Owners of the Global Note or Notes representing Book-Entry Notes
should consult the Participants through which they own their interest therein
for the respective deadlines for such Participants. All notices shall be
executed by a duly authorized officer of such Participant (with signatures
guaranteed) and will be irrevocable. In addition, Beneficial Owners of the
Global Note or Notes representing Book-Entry Notes shall effect delivery at the
time such notices of election are given to the Depositary by causing the
applicable Participant to transfer such Beneficial Owner's interest in the
Global Note or Notes representing such Book-Entry Notes, on the Depositary's
records, to the Trustee. See "Book-Entry System." (Section 3.04)
 
    If applicable, the Company will comply with the requirements of Rule 14e-1
under the Exchange Act, and any other securities laws or regulations in
connection with any such repayment.
 
REPURCHASE
 
    The Company may at any time purchase Notes at any price or prices in the
open market or otherwise. Notes so purchased by the Company may be held or
resold or, at the discretion of the Company, may be surrendered to the Trustee
for cancellation.
 
OTHER PROVISIONS
 
    Any provisions with respect to the determination of an Interest Rate Basis,
the specifications of an Interest Rate Basis, calculation of the interest rate
applicable to, or the principal payable at Maturity on, any Note, its Interest
Payment Dates or any other matter relating thereto may be modified by the terms

BOOK-ENTRY SYSTEM
 
    DTC will act as securities depositary for the Book-Entry Notes. The
Book-Entry Notes will be issued as fully-registered securities registered in the
name of Cede & Co. (DTC's partnership nominee). One fully-registered Global Note
will be issued for each issue of the Notes, each in the aggregate principal
amount of such issue, and will be deposited with DTC. If, however, the aggregate
principal amount of any issue exceeds the maximum principal amount (if any)
permitted by DTC, one Global Note will be issued with respect to such maximum
principal amount and an additional Global Note will be issued with respect to
any remaining principal amount of such issue.
 
    DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to Section 17A of the Exchange Act. DTC holds securities
that its participants ("Participants") deposit with DTC. DTC also facilitates
the settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct Participants ("Direct Participants")
include securities brokers and dealers, banks, trust companies, clearing
corporations, and certain other organizations. DTC is owned by a number of its
Direct Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to DTC's system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
    Purchases of Book-Entry Notes under DTC's system must be made by or through
Direct Participants, which will receive a credit for the Book-Entry Notes on
DTC's records. The ownership interest of each actual purchaser of each
Book-Entry Note ("Beneficial Owner") is in turn to be recorded on the Direct and
Indirect Participants' records. A Beneficial Owner will not receive written
confirmation from DTC of its purchase, but such Beneficial Owner is expected to
receive a written confirmation providing details of such transaction, as well as
periodic statements of its holdings, from the Direct or Indirect Participant
through which such Beneficial Owner entered into such transaction. Transfers of
ownership interests in the Book-Entry Notes are to be accomplished by entries
made on the books of Participants acting on behalf of the Beneficial Owners.
Beneficial Owners will not receive certificates representing their ownership
interests in Book-Entry Notes, except in the event that use of the book-entry
system for one or more Book-Entry Notes is discontinued.
 
    To facilitate subsequent transfers, all Global Notes deposited by
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of Global Notes with DTC and their registration in the
name of Cede & Co. effect no change in beneficial ownership. DTC has no
knowledge of the actual Beneficial Owners of the Book-Entry Notes; DTC's records
reflect only the identity of the Direct Participants to whose accounts such
Book-Entry Notes are credited, which may or may not be the Beneficial Owners.
The Participants will remain responsible for keeping account of their holdings
on behalf of their customers.
 
    Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
    Redemption notices for Book-Entry Notes shall be sent to Cede & Co. If less
than all of the Book-Entry Notes within an issue are being redeemed, DTC's
current practice is to determine by lot the amount of the interest of each
Direct Participant in such issue to be redeemed.
 
                                       19
<PAGE>
    Neither DTC nor Cede & Co. will consent or vote with respect to Book-Entry
Notes. Under its usual procedures, DTC will mail an "Omnibus Proxy" to the
issuer as soon as possible after the Record Date. The Omnibus Proxy assigns Cede
& Co.'s consenting or voting rights to those Direct Participants to whose
accounts the Book-Entry Notes are credited on the Record Date (identified in a
listing attached to the Omnibus Proxy).
 
    Principal and interest payments on the Book-Entry Notes will be made to DTC.
DTC's practice is to credit Direct Participants' accounts on the payable date in
accordance with their respective holdings shown on DTC's records unless DTC has
reason to believe that it will not receive payment on the payable date. Payments
by Participants to Beneficial Owners will be governed by standing instructions
and customary practices, as in the case of securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such Participants and not of DTC, the paying agent or the
Company, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of principal and interest to DTC is the
responsibility of the Company or the paying agent, disbursement of such payments
to Direct Participants is the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners is the responsibility of Direct and Indirect
Participants.
 
    A Beneficial Owner must give notice to elect to have its Book-Entry Notes
purchased or tendered, through its Participant, to the paying agent, and must
effect delivery of such Book-Entry Notes by causing the Direct Participant to
transfer the Participant's interest in the Book-Entry Notes, on DTC's records,
to the paying agent. The requirement for physical delivery of Book-Entry Notes
in connection with a demand for purchase or a mandatory purchase will be deemed
satisfied when the ownership rights in the Book-Entry Notes are transferred by
Direct Participants on DTC's records.
 
    If DTC is at any time unwilling or unable to continue as depositary or if
DTC ceases to be a "clearing agency" registered pursuant to Section 17A of the
Exchange Act, and, in either case, a successor depositary is not appointed by
the Company within 90 days, or if 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, the Company will issue individual Certificated Notes in
exchange for Book-Entry Notes represented by Global Notes. In addition, the
Company may at any time, and in its sole discretion, determine that one or more
Book-Entry Notes will no longer be represented by one or more Global Notes and,
in such event, will issue individual Certificated Notes in exchange for
Book-Entry Notes represented by such Global Notes.
 
    The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor Notes depositary). In that event,
Certificated Notes will be printed and delivered in exchange for the Book-Entry
Notes represented by the Global Notes held by DTC.
 
    The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Company believes to be reliable, but the
Company takes no responsibility for the accuracy thereof. So long as DTC or its
nominee is the registered owner of a Global Note, DTC or its nominee, as the
case may be, will be considered the sole Holder of the Notes represented by such
Global Note for all purposes under the Indenture. Except as provided above,
owners of beneficial interests in a Global Note will not be entitled to have the
Note represented by such Global Note registered in their names, will not receive
or be entitled to receive physical delivery of such Note in certificated form
and will not be considered the owners or Holders thereof under the Indenture.
The laws of some states require that certain purchasers of securities take
physical delivery of such securities in certificated form; accordingly, such
laws may limit the transferability of beneficial interests in a Global Note.
 
    None of the Company, the Agent, the Trustee, any paying agent or the
registrar for the Notes 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. (Section 2.12)

EXCHANGE, REGISTRATION AND TRANSFER
 
    Notes will be exchangeable for registered Notes of like aggregate principal
amount and of like Stated Maturity (as defined below under "Certain
Definitions") and with like terms and conditions. Upon surrender for
registration of transfer of any Note at the office or agency of the Company
maintained for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee, one or more
new registered Notes of the like aggregate principal amount of such
denominations as are authorized for Notes of a like Stated Maturity and with
like terms and conditions. No service charge will be made for any transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
(Section 3.05)
 
    The Company shall not be required (i) to register, transfer or exchange
Notes during a period beginning at the opening of business 15 days before the
day of the transmission of a notice of redemption of Notes of a like Stated
Maturity and with like terms and conditions selected for redemption and ending
at the close of business on the day of such transmission, or (ii) to register,
transfer or exchange any Note so selected for redemption in whole or in part,
except the unredeemed portion of any Note being redeemed in part. (Section 3.05)
 
EVENTS OF DEFAULT
 
    Under the Indenture, "Event of Default" with respect to any Note means any
one of the following events (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law,
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body): (1) default in the
payment of any interest upon any Note when it becomes due and payable, and
continuance of such default for a period of 30 days; (2) default in the payment
of the principal of (and premium, if any, on) any Note at its Maturity; (3)
default in the performance or breach of any covenant or warranty in the
Indenture (other than a covenant or warranty a default in whose performance or
whose breach is elsewhere in the Indenture specifically dealt with), and
continuance of such default or breach for a period of 60 days after there has
been given to the Company by the Trustee or to the Company and the Trustee by
the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, a written notice specifying such default or breach and requiring it
to be remedied; (4) default (i) in the payment of any principal of or interest
on any Indebtedness of the Company or any Subsidiary of the Company (other than
Notes), aggregating more than $10,000,000 in principal amount, when due after
giving effect to any applicable grace period or (ii) in the performance of any
other term or provision of any Indebtedness of the Company or any Subsidiary of
the Company (other than Notes) in excess of $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 to the Company by the Trustee or to the Company and the Trustee by the
Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, a written notice specifying such default or defaults; (5) the entry
against the Company or any Subsidiary of the Company of one or more judgments,
decrees or orders by a court from which no appeal may be or is taken for the
payment of money, either individually or in the aggregate, in excess of
$10,000,000, and the continuance of such judgment, decree or order unsatisfied
and in effect for any period of 45 consecutive days after the amount thereof is
due without a stay of execution; (6) certain events of bankruptcy, insolvency or
reorganization with respect to the Company; or (7) any other Event of Default
with respect to the subject Note described in the applicable Prospectus
Supplement. (Section 8.01)
 
    The Indenture requires the Company to file with the Trustee, annually, an
officer's certificate as to the Company's compliance with all conditions and
covenants under the Indenture. (Section 6.04) The Indenture provides that the
Trustee may withhold notice to the Holders of Notes of any default (except
 
                                       21
<PAGE>
payment defaults on any Note) if it determines that the withholding of such
notice is in the interest of the Holders of such Notes. (Section 8.12)
 
    If an Event of Default with respect to the Notes at the time outstanding
occurs and is continuing, then in every case the Trustee or the Holders of not
less than 25% in aggregate principal amount of the Notes then outstanding may
declare the principal amount (or, if any Notes are Original Issue Discount
Notes, the Amortized Face Amount) of all the Notes to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or Amortized
Face 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 (except as otherwise
provided in the Indenture or the Prospectus Supplement). (Section 8.02)
 
    Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default with respect to the Notes shall occur and
be continuing, the Trustee shall be under no obligation to exercise any of its
rights or powers under the Indenture at the request or direction of any of the
Holders of the Notes 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.
(Section 9.03) The Holders of a majority in principal amount of the outstanding
Notes shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee under the Indenture, or
exercising any trust or power conferred on the Trustee with respect to the
Notes, unless the Trustee determines that the proceeding or action so directed
may not lawfully be taken, would involve the Trustee in personal liability or
would be unduly prejudicial to other Holders of Notes. (Section 8.11)
 
    At any 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 provided in the Indenture, 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 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 the Notes which have become due solely by such declaration
of acceleration, have been cured or waived as provided in the Indenture. No such
rescission and waiver will affect any subsequent default or impair any right
consequent thereon. (Section 8.02)
 
MERGER OR CONSOLIDATION
 
    The Indenture provides that the Company may not consolidate with or merge
into any other corporation or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, (1) unless the corporation
formed by such consolidation or into which the Company is merged or the Person
which acquires by conveyance or transfer, or which leases, the properties and
assets of the Company substantially as an entirety (the "successor corporation")
is a corporation organized and existing under the laws of the United States or
any State or the District of Columbia and expressly assumes by a supplemental
indenture 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 the Indenture
on the part of the Company to be performed or observed; (2) unless immediately
after giving effect to such transaction, no Event of Default, and no event
which, after notice or lapse of time, or both, would become an Event of Default,
 
                                       22
<PAGE>
shall have occurred and be continuing; (3) if, as a result of any such
consolidation or merger or such conveyance, 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 the
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 such successor corporation or Person, as the case may
be, will take such steps as will be necessary effectively to secure all Notes
equally and ratably with (or prior to) all indebtedness secured thereby; and (4)
unless 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 the provisions of
the Indenture and that all conditions precedent therein provided for relating to
such transaction have been complied with. (Section 12.01)
 
MODIFICATION OR WAIVER
 
    Without the consent of any Holders, the Company and the Trustee, at any time
and from time to time, may enter into a supplemental indenture for any of the
following purposes: (1) to make such provision in regard to matters or questions
arising under the Indenture as may be necessary or desirable and not
inconsistent with the Indenture or for the purpose of supplying any omission,
curing any ambiguity, or curing, correcting or supplementing any defective or
inconsistent provision; PROVIDED that such provisions may not adversely affect
the interests of Holders of outstanding Notes created prior to the execution of
such supplemental indenture in any material respect; (2) to change or eliminate
any of the provisions of this Indenture; PROVIDED that any such change or
elimination shall become effective only when there is no outstanding Note
created prior to the execution of such supplemental indenture which is entitled
to the benefit of such provision; (3) to secure the Notes; (4) to establish the
form of Notes as permitted by the Indenture or to establish or reflect any terms
of any Note determined in accordance with the Indenture; (5) to evidence the
succession of another corporation to the Company, and the assumption by any such
successor of the covenants of the Company in the Indenture and in the Notes; (6)
to grant to or confer upon the Trustee for the benefit of the Holders any
additional rights, remedies, powers or authority; (7) to permit the Trustee to
comply with any duties imposed upon it by law; (8) to specify further the duties
and responsibilities of, and to define further the relationships among, the
Trustee, any Authenticating Agent and any paying agent; (9) to add to the
covenants of the Company for the benefit of the Holders of all or any Notes (and
if such covenants are to be for the benefit of less than all Notes, stating that
such covenants are expressly being included solely for the benefit of such
Notes), or to surrender a right or power conferred on the Company in the
Indenture; and (10) to add any additional Events of Default (and if such Events
of Default are to be applicable to less than all Notes, stating that such Events
of Default are expressly being included for the benefit of such Notes). (Section
13.01)
 
    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 by the
particular supplemental indenture, the Company and the Trustee, may at any time
and from time to time, enter into a supplemental indenture for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of the Indenture or of modifying in any manner the rights of the
Holders of such Notes; PROVIDED, HOWEVER, that no such supplemental indenture
may (i) change the Stated Maturity of any Note; or reduce the rate of interest
on any Note; or change the method of calculating interest, or any term used in
the calculation of interest or the period for which interest is payable, on any
Floating Rate Note; or reduce the principal amount of any Note or any premium
thereon, or reduce the amount of the principal of an Original Issue Discount
Note that would be due and payable upon a declaration of acceleration of the
Maturity thereof, or adversely affect the right of repayment or renewal, if any,
at the option of the Holder; or change the currency of payment of any Note; or
change the date on which any Note may be redeemed; or adversely affect the
rights of any Holder to institute suit for the enforcement of any payment of
principal of or any premium or interest on any Note; in each case without the
consent of the Holder of each Note then outstanding that would be affected
thereby, including Notes for which an offer to purchase has been accepted by the
 
                                       23
<PAGE>
Company, or (ii) reduce the aforesaid percentage of the principal amount of
Notes, the Holders of which are required to consent to any such supplemental
indenture, or the percentage in aggregate principal amount of the Notes then
outstanding, the consent of the Holders of which is required for any waiver of
certain past defaults or Events of Default hereunder or the consequences
thereof, in each case without the consent of the Holders of all of the Notes
then outstanding. (Section 13.02)
 
    Prior to any declaration accelerating the Maturity of the Notes, the Holders
of not less than a majority in aggregate principal amount of the Notes then
outstanding may on behalf of the Holders of all the Notes waive any past default
or Event of Default under the Indenture and its consequences, except a default
(1) in the payment of the principal of or any premium or interest on any Note,
or (2) in respect of a covenant or provision hereof which pursuant to the second
paragraph under "Modification or Waiver" 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 will extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon. (Section 8.11)
 
    The Company may omit in any particular instance to comply with the covenants
in the Indenture described above under "Restrictions on Secured Debt" (and if so
specified in the applicable Prospectus Supplement, any covenant not set forth in
the Indenture but specified in such Prospectus Supplement to be applicable to
any Note, except as otherwise provided in such Prospectus Supplement), if before
the time for such compliance the Holders of at least a majority in aggregate
principal amount of the Notes then outstanding either waive such compliance in
such instance or generally waive compliance with such covenants, but no such
waiver may extend to or affect any covenant except to the extent expressly so
waived, and, until such waiver becomes effective, the obligations of the Company
and the duties of the Trustee in respect of any such covenant will remain in
full force and effect. (Section 6.07)
 
DISCHARGE OF INDENTURE
 
    The Indenture may be discharged, subject to certain terms and conditions,
when (1) either (A) all Notes theretofore authenticated and delivered 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, (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, 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 the case may be;
PROVIDED, HOWEVER, in the event a petition for relief under any 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 the Indenture with respect to such Notes will not be deemed
terminated or discharged; (2) the Company has paid or caused to be paid all
other sums payable under the Indenture 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 therein provided for relating to the
satisfaction and discharge of the Indenture with respect to the Notes have been
complied with; and (4) the Company has delivered to the Trustee an opinion of
counsel or a ruling of 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. (Section 5.01)
 
                                       24
<PAGE>
PAYMENT AND PAYING AGENTS
 
    So long as any of the Notes remain outstanding, the Company will maintain in
the Borough of Manhattan, The City of New York, an office or agency where the
Notes may be presented for registration of transfer and for exchange as in the
Indenture provided, and where, at any time when the Company is obligated to make
a payment upon Notes (other than a payment which it is permitted to make by
check), the Notes may be presented for payment, and will 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 the 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 has appointed the Trustee as agent of the Company for the
foregoing purposes. (Section 6.02)
 
REGARDING THE TRUSTEE
 
    The First National Bank of Chicago is one of a number of banks with which
the Company maintains ordinary banking relationships and from which the Company
has obtained credit facilities and lines of credit, and acts as the trustee
under an indenture under which subordinated debentures of the Company may be or
become outstanding.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following summary describes the principal United States federal income
tax consequences of the purchase, ownership and disposition of Notes to
beneficial owners ("holders") of Notes purchasing Notes at their original
issuance. This summary is based on the Internal Revenue Code of 1986, as amended
(the "Code"), legislative history, administrative pronouncements, judicial
decisions and final, temporary and proposed Treasury Regulations, changes to any
of which subsequent to the date hereof may affect the tax consequences described
herein. Any such change may apply retroactively. This summary is also based on
final Treasury Regulations (the "1996 OID Regulations") published by the
Internal Revenue Service ("IRS") on June 14, 1996, which set forth rules
applicable to "contingent payment debt instruments."
 
    This summary discusses only the principal United States federal income tax
consequences to those holders holding Notes as capital assets within the meaning
of Section 1221 of the Code. It does not address all of the tax consequences
that may be relevant to a holder in light of the holder's particular
circumstances or to holders subject to special rules (including pension plans
and other tax-exempt investors, banks, thrifts, insurance companies, real estate
investment trusts, regulated investment companies, dealers in securities,
currencies and persons so treated for federal income tax purposes, persons whose
functional currency (as defined in Section 985 of the Code) is other than the
United States dollar, and persons who hold Notes as part of a straddle, hedging
or conversion transaction). This summary also assumes that a taxpayer obtains
any necessary consent of the IRS before changing a method of accounting.
 
    Persons considering the purchase of Notes should consult their tax advisors
with regard to the application of United States federal income tax laws to their
particular situations as well as any tax consequences to them arising under the
laws of any state, local or foreign taxing jurisdiction. State, local and
foreign income tax laws may differ substantially from the corresponding federal
income tax laws, and this discussion does not purport to describe any aspect of
the tax laws of any state, local or foreign jurisdiction. Therefore, potential
investors should consult their own tax advisors with respect to the various
state, local and foreign tax consequences of an investment in Notes.
 
    As used herein, the term "United States Holder" means a beneficial owner of
a Note who or which is, for United States federal income tax purposes, either
(i) a citizen or resident of the United States, (ii) a corporation or
partnership created or organized in or under the laws of the United States or of
any
 
                                       26
<PAGE>
political subdivision thereof or (iii) an estate or trust the income of which is
subject to United States federal income taxation regardless of its source. The
term also includes certain holders who are former citizens of the United States
whose income and gain from the Notes will be subject to United States taxation.
 
TAXATION OF INTEREST
 
    The taxation of interest on a Note depends on whether it constitutes
"qualified stated interest" (as defined below). Interest on a Note that
constitutes qualified stated interest is includible in a United States Holder's
income as ordinary interest income when actually or constructively received, if
such Holder uses the cash method of accounting for federal income tax purposes,
or when accrued, if such Holder uses an accrual method of accounting for federal
income tax purposes. Interest that does not constitute qualified stated interest
is included in a United States Holder's income under the rules described below
under "Original Issue Discount," regardless of such Holder's method of
accounting. Notwithstanding the foregoing, interest that is payable on a Note
with a maturity of one year or less from its issue date (a "Short-Term Note") is
included in a United States Holder's income under the rules described below
under "Short-Term Notes."
 
  FIXED RATE NOTES
 
    Interest on a Fixed Rate Note will constitute "qualified stated interest" if
the interest is unconditionally payable, or will be constructively received
under Section 451 of the Code, in cash or in property (other than debt
instruments of the Company) at least annually at a single fixed rate.
 
  FLOATING RATE NOTES
 
    Interest on a Floating Rate Note that is unconditionally payable, or will be
constructively received under Section 451 of the Code, in cash or in property
(other than debt instruments of the Company) at least annually will constitute
"qualified stated interest" if the Note is a "variable rate debt instrument"
("VRDI") under the rules described below and the interest is payable at a single
"qualified floating rate" or single "objective rate" (each as defined below). If
the Note is a VRDI but the interest is payable other than at a single qualified
floating rate or at a single objective rate, special rules apply to determine
the portion of such interest that constitutes "qualified stated interest." See
"Original Issue Discount Floating--RATE NOTES THAT ARE VRDIS," below.
 
  DEFINITION OF VARIABLE RATE DEBT INSTRUMENT (VRDI), QUALIFIED FLOATING RATE
  AND OBJECTIVE RATE
 
    A Note is a VRDI if all of the four following conditions are met. First, the
"issue price" of the Note (as described below) must not exceed the total
noncontingent principal payments by more than an amount equal to the lesser of
(i) .015 multiplied by the product of the total noncontingent principal payments
and the number of complete years to maturity from the issue date (or, in the
case of a Note that provides for payment of any amount other than qualified
stated interest before maturity, its weighted average maturity) and (ii) 15% of
the total noncontingent principal payments.
 
    Second, the Note must provide for stated interest (compounded or paid at
least annually) at (a) one or more qualified floating rates, (b) a single fixed
rate and one or more qualified floating rates, (c) a single objective rate or
(d) a single fixed rate and a single objective rate that is a "qualified inverse
floating rate" (as defined below).
 
    Third, the Note must provide that a qualified floating rate or objective
rate in effect at any time during the term of the Note is set at the value of
the rate on any day that is no earlier than three months prior to the first day
on which that value is in effect and no later than one year following that first
day.
 
                                       27
<PAGE>
    Fourth, the Note may not provide for any principal payments that are
contingent except as provided in the first requirement set forth above.
 
    Subject to certain exceptions, a variable rate of interest on a Note is a
"qualified floating rate" if variations in the value of the rate can reasonably
be expected to measure contemporaneous fluctuations in the cost of newly
borrowed funds in United States dollars. A variable rate will be considered a
qualified floating rate if the variable rate equals (i) the product of an
otherwise qualified floating rate and a fixed multiple (I.E., a Spread
Multiplier) that is greater than 0.65, but not more than 1.35 or (ii) an
otherwise qualified floating rate (or the product described in clause (i)) plus
or minus a fixed rate (I.E., a Spread). If the variable rate equals the product
of an otherwise qualified floating rate and a single Spread Multiplier greater
than 1.35 or less than or equal to 0.65, however, such rate will generally
constitute an objective rate, described more fully below. A variable rate will
not be considered a qualified floating rate if the variable rate is subject to a
cap, floor, governor (I.E., a restriction on the amount of increase or decrease
in the stated interest rate) or similar restriction that is reasonably expected
as of the issue date to cause the yield on the Note to be significantly more or
less than the expected yield determined without the restriction (other than a
cap, floor or governor that is fixed throughout the term of the Note).
 
    Subject to certain exceptions, an "objective rate" is a rate (other than a
qualified floating rate) that is determined using a single fixed formula and
that is based on objective financial or economic information that is neither
within the control of the Company (or a related party) nor unique to the
circumstances of the Company (or a related party). For example, an objective
rate generally includes a rate that is based on one or more qualified floating
rates or on the yield of actively traded personal property (within the meaning
of Section 1092(d)(1) of the Code). Notwithstanding the first sentence of this
paragraph, a rate on a Note is not an objective rate if it is reasonably
expected that the average value of the rate during the first half of the Note's
term will be either significantly less than or significantly greater than the
average value of the rate during the final half of the Note's term. An objective
rate is a "qualified inverse floating rate" if (a) the rate is equal to a fixed
rate minus a qualified floating rate and (b) the variations in the rate can
reasonably be expected to reflect inversely contemporaneous variations in the
cost of newly borrowed funds (disregarding any caps, floors, governors or
similar restrictions that would not, as described above, cause a rate to fail to
be a qualified floating rate).
 
    If interest on a Note is stated at a fixed rate for an initial period of
less than one year, followed by a variable rate that is either a qualified
floating rate or an objective rate for a subsequent period, and the value of the
variable rate on the issue date is intended to approximate the fixed rate, the
fixed rate and the variable rate together constitute a single qualified floating
rate or objective rate.
 
ORIGINAL ISSUE DISCOUNT
 
    Original issue discount ("OID") with respect to a Note is the excess, if
any, of the Note's "stated redemption price at maturity" over the Note's "issue
price." A Note's "stated redemption price at maturity" is the sum of all
payments provided by the Note (whether designated as interest or as principal)
other than payments of qualified stated interest. The "issue price" of a Note is
the first price at which a substantial amount of the Notes in the issuance that
includes such Note is sold for money (excluding sales to bond houses, brokers or
similar persons or organizations acting in the capacity of underwriters,
placement agents or wholesalers).
 
    As described more fully below, United States Holders of Notes with OID that
mature more than one year from their issue date generally will be required to
include such OID in income as it accrues in accordance with the constant yield
method described below, irrespective of the receipt of the related cash
payments. A United States Holder's tax basis in a Note is increased by each
accrual of OID and decreased by each payment other than a payment of qualified
stated interest.
 
    The amount of OID with respect to a Note will be treated as zero if the OID
is less than an amount equal to .0025 multiplied by the product of the stated
redemption price at maturity and the number of
 
                                       28
<PAGE>
complete years to maturity (or, in the case of a Note that provides for payment
of any amount other than qualified stated interest prior to maturity, the
weighted average maturity of the Note). If the amount of OID with respect to a
Note is less than that amount, the OID that is not included in payments of
stated interest is generally included in income as capital gain as principal
payments are made. The amount includible with respect to a principal payment
equals the product of the total amount of OID and a fraction, the numerator of
which is the amount of such principal payment and the denominator of which is
the stated principal amount of the Note.
 
  FIXED RATE NOTES
 
    In the case of OID with respect to a Fixed Rate Note, the amount of OID
includible in the income of a United States Holder for any taxable year is
determined under the constant yield method, as follows. First, the "yield to
maturity" of the Note is computed. The yield to maturity is the discount rate
that, when used in computing the present value of all interest and principal
payments to be made under the Note (including payments of qualified stated
interest), produces an amount equal to the issue price of the Note. The yield to
maturity is constant over the term of the Note and, when expressed as a
percentage, must be calculated to at least two decimal places.
 
    Second, the term of the Note is divided into "accrual periods." Accrual
periods may be of any length and may vary in length over the term of the Note,
provided that each accrual period is no longer than one year and that each
scheduled payment of principal or interest occurs either on the final day of an
accrual period or on the first day of an accrual period.
 
    Third, the total amount of OID on the Note is allocated among accrual
periods. In general, the OID allocable to an accrual period equals the product
of the "adjusted issue price" of the Note at the beginning of the accrual period
and the yield to maturity of the Note, less the amount of any qualified stated
interest allocable to the accrual period. The adjusted issue price of a Note at
the beginning of the first accrual period is its issue price. Thereafter, the
adjusted issue price of the Note is its issue price, increased by the amount of
OID previously includible in the gross income of any holder and decreased by the
amount of any payment previously made on the Note other than a payment of
qualified stated interest. For purposes of computing the adjusted issue price of
a Note, the amount of OID previously includible in the gross income of any
holder is determined without regard to "premium" and "acquisition premium," as
those terms are defined below under "Premium and Acquisition Premium."
 
    Fourth, the "daily portions" of OID are determined by allocating to each day
in an accrual period its ratable portion of the OID allocable to the accrual
period.
 
    A United States Holder includes in income in any taxable year the daily
portions of OID for each day during the taxable year that such Holder held
Notes. In general, under the constant yield method described above, United
States Holders will be required to include in income increasingly greater
amounts of OID in successive accrual periods.
 
  FLOATING RATE NOTES THAT ARE VRDIS
 
    The taxation of OID (including interest that does not constitute qualified
stated interest) on a Floating Rate Note will depend on whether the Note is a
"VRDI," as that term is defined above under "Taxation of Interest--DEFINITION OF
VARIABLE RATE DEBT INSTRUMENT (VRDI), QUALIFIED FLOATING RATE AND OBJECTIVE
RATE."
 
    In the case of a VRDI that provides for qualified stated interest, the
amount of qualified stated interest and the amount of OID, if any, includible in
income during a taxable year are determined under the rules applicable to Fixed
Rate Notes (described above) by assuming that the variable rate is a fixed rate
equal to (i) in the case of a qualified floating rate or a qualified inverse
floating rate, the value, as of the issue date, of the qualified floating rate
or qualified inverse floating rate, or (ii) in the case of an objective
 
                                       29
<PAGE>
rate (other than a qualified inverse floating rate), the rate that reflects the
yield that is reasonably expected for the Note. Qualified stated interest
allocable to an accrual period is increased (or decreased) if the interest
actually paid during an accrual period exceeds (or is less than) the interest
assumed to be paid during the accrual period.
 
    If a Note that is a VRDI does not provide for interest at a single variable
rate as described above, the amount of interest and OID accruals are determined
by constructing an equivalent fixed rate debt instrument, as follows.
 
    First, in the case of an instrument that provides for interest at one or
more qualified floating rates or at a qualified inverse floating rate and, in
addition, at a fixed rate, replace the fixed rate with a qualified floating rate
(or qualified inverse floating rate) such that the fair market value of the
instrument, so modified, as of the issue date would be approximately the same as
the fair market value of the unmodified instrument.
 
    Second, determine the fixed rate substitute for each variable rate provided
by the Note. The fixed rate substitute for each qualified floating rate provided
by the Note is the value of that qualified floating rate on the issue date. If
the Note provides for two or more qualified floating rates with different
intervals between interest adjustment dates (for example, the 30-day Commercial
Paper Rate and quarterly LIBOR), the fixed rate substitutes are based on
intervals that are equal in length (for example, the 90-day Commercial Paper
Rate and quarterly LIBOR, or the 30-day Commercial Paper Rate and monthly
LIBOR). The fixed rate substitute for an objective rate that is a qualified
inverse floating rate is the value of the qualified inverse floating rate on the
issue date. The fixed rate substitute for an objective rate (other than a
qualified inverse floating rate) is a fixed rate that reflects the yield that is
reasonably expected for the Note.
 
    Third, construct an equivalent fixed rate debt instrument that has terms
that are identical to those provided under the Note, except that the equivalent
fixed rate debt instrument provides for the fixed rate substitutes determined in
the second step, in lieu of the qualified floating rates or objective rate
provided by the Note.
 
    Fourth, determine the amount of qualified stated interest and OID for the
equivalent fixed rate debt instrument under the rules (described above) for
Fixed Rate Notes. These amounts are taken into account as if the United States
Holder held the equivalent fixed rate debt instrument. See "Taxation of
Interest" and "Original Issue Discount--FIXED RATE NOTES," above.
 
    Fifth, make appropriate adjustments for the actual values of the variable
rates. In this step, qualified stated interest or OID allocable to an accrual
period is increased (or decreased) if the interest actually accrued or paid
during the accrual period exceeds (or is less than) the interest assumed to be
accrued or paid during the accrual period under the equivalent fixed rate debt
instrument.
 
  FLOATING RATE NOTES THAT ARE NOT VRDIS
 
    The tax treatment of Floating Rate Notes that are not VRDIs ("Contingent
Notes") is as follows. First, the Company is required to determine, as of the
issue date, the comparable yield for the Contingent Note. The comparable yield
is generally the yield at which the Company would issue a fixed rate debt
instrument with terms and conditions similar to those of the Contingent Note
(including the level of subordination, term, timing of payments and general
market conditions, but not taking into consideration the riskiness of the
contingencies or the liquidity of the Contingent Note), but not less than the
applicable federal rate announced monthly by the IRS (the "AFR"). In certain
cases where Contingent Notes are marketed or sold in substantial part to
tax-exempt investors or other investors for whom the prescribed inclusion of
interest is not expected to have a substantial effect on their U.S. tax
liability, the comparable yield for the Contingent Note, without proper evidence
to the contrary, is presumed to be the AFR.
 
    Second, solely for tax purposes, the Company constructs a projected schedule
of payments determined under the 1996 OID Regulations for the Contingent Note
(the "Schedule"). The Schedule is determined
 
                                       30
<PAGE>
as of the issue date and generally remains in place throughout the term of the
Contingent Note. If a right to a contingent payment is based on market
information, the amount of the projected payment is the forward price of the
contingent payment. If a contingent payment is not based on market information,
the amount of the projected payment is the expected value of the contingent
payment as of the issue date. The Schedule must produce the comparable yield
determined as set forth above. Otherwise, the Schedule must be adjusted under
the rules set forth in the 1996 OID Regulations.
 
    Third, under the usual rules applicable to OID and based on the Schedule,
the interest income on the Contingent Note for each accrual period is determined
by multiplying the comparable yield of the Contingent Note (adjusted for the
length of the accrual period) by the Contingent Note's adjusted issue price at
the beginning of the accrual period (determined under rules set forth in the
1996 OID Regulations). The amount so determined is then allocated on a ratable
basis to each day in the accrual period that the United States Holder held the
Contingent Note.
 
    Fourth, appropriate adjustments are made to the interest income determined
under the foregoing rules to account for any differences between the Schedule
and actual contingent payments. Under the rules set forth in the 1996 OID
Regulations, differences between the actual amounts of any contingent payments
made in a calendar year and the projected amounts of such payments are generally
aggregated and taken into account, in the case of a positive difference, as
additional interest income, or, in the case of a negative difference, first as a
reduction in interest income for such year and thereafter, subject to certain
limitations, as ordinary loss.
 
    The Company is required to provide each holder of a Contingent Note with the
Schedule described above. If the Company does not create a Schedule or the
Schedule is unreasonable, a United States Holder must set its own projected
payment schedule and explicitly disclose the use of such schedule and the reason
therefor. Unless otherwise prescribed by the IRS, the United States Holder must
make such disclosure on a statement attached to the United States Holder's
timely filed federal income tax return for the taxable year in which the
Contingent Note was acquired.
 
    In general, any gain realized by a United States Holder on the sale,
exchange or retirement of a Contingent Note is interest income. In general, any
loss on a Contingent Note accounted for under the method described above is
ordinary loss to the extent it does not exceed such Holder's prior interest
inclusions on the Contingent Note (net of negative adjustments). Special rules
apply in determining the tax basis of a Contingent Note and the amount realized
on the retirement of a Contingent Note.
 
  OTHER RULES
 
    Certain Notes having OID may be redeemed prior to maturity or may be
repayable at the option of the holder. Such Notes may be subject to rules that
differ from the general rules discussed above relating to the tax treatment of
OID. Purchasers of such Notes with a redemption feature should consult their tax
advisors with respect to such feature since the tax consequences with respect to
original issue discount will depend, in part, on the particular terms and the
particular features of the purchased Note.
 
    The Treasury Regulations relating to the tax treatment of OID contain
certain language ("aggregation rules") stating in general that, with some
exceptions, if more than one type of Note is issued in connection with the same
transaction or related transactions, such Notes may be treated as a single debt
instrument with a single issue price, maturity date, yield to maturity and
stated redemption price at maturity for purposes of calculating and accruing any
OID. Unless otherwise provided in the applicable Prospectus Supplement, the
Company does not expect to treat different types of Notes as being subject to
the aggregation rules for purposes of computing OID.
 
                                       31
<PAGE>
MARKET DISCOUNT
 
    If a United States Holder acquires a Note having a maturity date of more
than one year from the date of its issuance and has a tax basis in the Note that
is, in the case of a Note that does not have OID, less than its stated
redemption price at maturity, or, in the case of a Note that has OID, less than
its adjusted issue price (as defined above), the amount of such difference is
treated as "market discount" for federal income tax purposes, unless such
difference is less than 1/4 of one percent of the stated redemption price at
maturity multiplied by the number of complete years to maturity (from the date
of acquisition).
 
    Under the market discount rules of the Code, a United States Holder is
required to treat any principal payment (or, in the case of a Note that has OID,
any payment that does not constitute a payment of qualified stated interest) on,
or any gain on the sale, exchange, retirement or other disposition of, a Note as
ordinary income to the extent of the accrued market discount that has not
previously been included in income. Thus, partial principal payments are treated
as ordinary income to the extent of accrued market discount that has not
previously been included in income. If such Note is disposed of by the United
States Holder in certain otherwise nontaxable transactions, accrued market
discount will be includible as ordinary income by the United States Holder as if
such Holder had sold the Note at its then fair market value.
 
    In general, the amount of market discount that has accrued is determined on
a ratable basis. A United States Holder may, however, elect to determine the
amount of accrued market discount on a constant yield to maturity basis. This
election is made on a Note-by-Note basis and is irrevocable.
 
    With respect to Notes with market discount, a United States Holder may not
be allowed to deduct immediately a portion of the interest expense on any
indebtedness incurred or continued to purchase or to carry such Notes. A United
States Holder may elect to include market discount in income currently as it
accrues, in which case the interest deferral rule set forth in the preceding
sentence will not apply. Such an election will apply to all debt instruments
acquired by the United States Holder on or after the first day of the first
taxable year to which such election applies and is irrevocable without the
consent of the IRS. A United States Holder's tax basis in a Note will be
increased by the amount of market discount included in such Holder's income
under such an election.
 
    In lieu of the foregoing rules, different rules apply in the case of
Contingent Notes where a holder's tax basis in a Contingent Note is less than
the Contingent Note's adjusted issue price (determined under special rules set
out in the 1996 OID Regulations). Accordingly, prospective purchasers of
Contingent Notes should consult with their tax advisors with respect to the
application of such rules to such Notes.
 
PREMIUM AND ACQUISITION PREMIUM
 
    A United States Holder will be treated as having purchased a Note at a
"premium" (or "amortizable bond premium") if the Note's adjusted basis,
immediately after its purchase by such Holder, exceeds the sum of all amounts
payable on the Note after the purchase date other than payments of qualified
stated interest. United States Holders may elect to amortize the premium over
the remaining term of the Note (where such Note is not callable prior to its
maturity date), as a reduction in the amount of the interest payments otherwise
includible in income, and the United States Holder will not be required to
include in income OID (if any) with respect to any Note purchased at a premium.
If such Note may be called by the Company prior to maturity after the United
States Holder has acquired it, the amount of amortizable bond premium is
determined with reference to either the amount payable at maturity, or, if it
results in a smaller premium attributable to the period through the earlier call
date, with reference to the amount payable on the earlier call date. If a United
States Holder makes this election, the premium will be allocated among all the
interest payments on the Note, on the basis of the United States Holders's yield
to maturity, with compounding at the close of each accrual period. A United
States Holder who elects to amortize premium must reduce the tax basis of the
Note by the amount of the premium amortized in any year. If this election is
made with respect to any Note, it will also apply to all debt instruments held
by the United States Holder at the beginning of the first taxable year to which
the election applies and to all debt instruments acquired
 
                                       32
<PAGE>
by the United States Holder, and will be binding for all subsequent taxable
years unless the election is revoked with the consent of the IRS.
 
    On June 27, 1996, the IRS published in the Federal Register proposed
regulations (the "Proposed Premium Regulations") on the amortization of bond
premium. The Proposed Premium Regulations describe the constant yield method
under which such premium is amortized and provide that the resulting offset to
interest income can be taken into account only as a United States Holder takes
the corresponding interest income into account under such holder's regular
accounting method. In the case of instruments that may be redeemed at the option
of the Company or repaid at the option of the holder prior to maturity, the
Proposed Premium Regulations provide that the premium is calculated by assuming
that the Company will exercise or not exercise its redemption rights in the
manner that maximizes the United States Holder's yield and the United States
Holder will exercise or not exercise its repayment option in a manner that
maximizes the United States Holder's yield. The Proposed Premium Regulations are
proposed to be effective for debt instruments acquired on or after the date 60
days after the date final regulations are published in the Federal Register.
However, if a United States Holder elects to amortize bond premium for the
taxable year containing such effective date, the Proposed Premium Regulations
would apply to all the United States Holder's debt instruments held on or after
the first day of that taxable year. It cannot be predicted at this time whether
the Proposed Premium Regulations will become effective or what, if any,
modifications will be made to them prior to their becoming effective.
 
    If a United States Holder purchases a Note issued with OID at an
"acquisition premium," the amount of OID that the United States Holder includes
in gross income is reduced to reflect the acquisition premium. A Note is
purchased at an acquisition premium if its adjusted basis, immediately after its
purchase, is (a) less than or equal to the sum of all amounts payable on the
Note after the purchase date other than payments of qualified stated interest
and (b) greater than the Note's "adjusted issue price" (as described above under
"Original Issue Discount--FIXED RATE NOTES").
 
    If a Note is purchased at an acquisition premium, the United States Holder
reduces the amount of OID otherwise includible in income during an accrual
period by an amount equal to (i) the amount of OID otherwise includible in
income multiplied by (ii) a fraction, the numerator of which is the excess of
the adjusted basis of the Note immediately after its acquisition by the
purchaser over the adjusted issue price of the Note and the denominator of which
is the excess of the sum of all amounts payable on the Note after the purchase
date, other than payments of qualified stated interest, over the Note's adjusted
issue price.
 
    As an alternative to reducing the amount of OID otherwise includible in
income by this fraction, the United States Holder may elect to compute OID
accruals by treating the purchase as a purchase at original issuance and
applying the constant yield method described above.
 
    In lieu of the foregoing rules, different rules apply in the case of
Contingent Notes where a holder's tax basis in a Contingent Note is greater than
the Contingent Note's adjusted issue price (determined under special rules set
out in the 1996 OID Regulations). Accordingly, prospective purchasers of
Contingent Notes should consult with their tax advisors with respect to the
application of such rules to such Notes.
 
SHORT-TERM NOTES
 
    In the case of a Short-Term Note, no interest is treated as qualified stated
interest, and therefore all interest is included in OID. United States Holders
that report income for federal income tax purposes on an accrual method and
certain other United States Holders, including banks and dealers in securities,
are required to include OID in income on such Short-Term Notes on a
straight-line basis, unless an election is made to accrue the OID according to a
constant yield method based on daily compounding.
 
    Any other United States Holder of a Short-Term Note is not required to
accrue OID for federal income tax purposes, unless it elects to do so, with the
consequence that the reporting of such income is
 
                                       33
<PAGE>
deferred until it is received. In the case of a United States Holder that is not
required, and does not elect, to include OID in income currently, any gain
realized on the sale, exchange or retirement of a Short-Term Note is ordinary
income to the extent of the OID accrued on a straight-line basis (or, if
elected, according to a constant yield method based on daily compounding)
through the date of sale, exchange or retirement. In addition, United States
Holders that are not required, and do not elect, to include OID in income
currently are required to defer deductions for any interest paid on indebtedness
incurred or continued to purchase or carry a Short-Term Note in an amount not
exceeding the deferred interest income with respect to such Short-Term Note
(which includes both the accrued OID and accrued interest that are payable but
that have not been included in gross income), until such deferred interest
income is realized. A United States Holder of a Short-Term Note may elect to
apply the foregoing rules (except for the rule characterizing gain on sale,
exchange or retirement as ordinary) with respect to "acquisition discount"
rather than OID. Acquisition discount is the excess of the stated redemption
price at maturity of the Short-Term Note over the United States Holder's basis
in the Short-Term Note. This election applies to all obligations acquired by the
taxpayer on or after the first day of the first taxable year to which such
election applies, unless revoked with the consent of the IRS. A United States
Holder's tax basis in a Short-Term Note is increased by the amount included in
such Holder's income on such a Note.
 
ELECTION TO TREAT ALL INTEREST AS OID
 
    United States Holders may elect to include in gross income all interest that
accrues on a Note, including any stated interest, acquisition discount, OID,
market discount, DE MINIMIS OID, DE MINIMIS market discount and unstated
interest (as adjusted by amortizable bond premium and acquisition premium), by
using the constant yield method described above under "Original Issue Discount."
Such an election for a Note with amortizable bond premium will result in a
deemed election to amortize bond premium for all debt instruments owned and
later acquired by the United States Holder with amortizable bond premium and may
be revoked only with the permission of the IRS. Similarly, such an election for
a Note with market discount will result in a deemed election to accrue market
discount in income currently for such Note and for all other debt instruments
acquired by the United States Holder with market discount on or after the first
day of the taxable year to which such election first applies, and may be revoked
only with the permission of the IRS. A United States Holder's tax basis in a
Note will be increased by each accrual of the amounts treated as OID under the
constant yield election described in this paragraph.
 
EXTENDIBLE NOTES, RENEWABLE NOTES AND RESET NOTES
 
    If so specified in an applicable Prospectus Supplement relating to a Note,
the Company or a holder may have the option to extend the maturity of or renew
such Note. See "Description of Notes--Extension of Maturity" and "Description of
Notes--Renewable Notes." In addition, the Company may have the option to reset
the interest rate, the Spread or the Spread Multiplier with respect to a Note.
See "Description of Notes--Reset Notes." The treatment of a United States Holder
of Notes to which such options apply will depend, in part, on the terms
established for such Notes by the Company pursuant to the exercise of such
option by the Company or a holder. Upon the exercise of any such option, the
United States Holder of such Notes may be treated for federal income tax
purposes as having exchanged such Notes (the "Old Notes") for new Notes with
revised terms (the "New Notes"). If such holder is treated as having exchanged
Old Notes for New Notes, such exchange may be treated as either a taxable
exchange or a tax-free recapitalization.
 
    Final Treasury Regulations under Section 1001 of the Code, published on June
26, 1996 (the "Final Section 1001 Regulations"), generally provide that the
exercise of an option provided to an issuer or a holder to change a term of a
debt instrument (such as the maturity or the interest rate) in a manner such as
that contemplated for Extendible Notes, Renewable Notes and Reset Notes will
create a deemed exchange of Old Notes for New Notes if such exercise modifies
such terms to a degree that is "economically
 
                                       34
<PAGE>
significant." With respect to certain types of debt instruments, under the Final
Section 1001 Regulations a deemed exchange for tax purposes occurs if the
exercise of such an option alters the annual yield of the debt instrument by
more than the greater of (i) 25 basis points or (ii) 5 percent of the annual
yield of the debt instrument prior to modification. The exercise of an option
that changes the timing of payments under a debt instrument creates a deemed
exchange under the Final Section 1001 Regulations (whether or not the annual
yield is altered) if there is a "material deferral" of scheduled payments. In
this connection, the Final Section 1001 Regulations generally provide that a
deferral of scheduled payments within a safe-harbor period which begins on the
original due date for the first deferred payment and extends for a period not
longer than the lesser of five years or 50 percent of the original term of the
debt instrument will not be considered to be a material deferral.
 
    If the exercise of the option by the Company or a holder is not treated as
an exchange of Old Notes for New Notes, no gain or loss will be recognized by a
United States Holder as a result thereof. If the exercise of the option is
treated as a taxable exchange of Old Notes for New Notes, a United States Holder
will recognize gain or loss equal to the difference between the issue price of
the New Notes and such Holder's tax basis in the Old Notes. However, if the
exercise of the option is treated as a tax-free recapitalization, no loss will
be recognized by a United States Holder as a result thereof and gain, if any,
will be recognized to the extent of the fair market value of the excess, if any,
of the principal amount of securities received over the principal amount of
securities surrendered. In this regard, the meaning of the term "principal
amount" is not clear. Such term could be interpreted to mean "issue price" with
respect to securities that are received and "adjusted issue price" with respect
to securities that are surrendered. Legislation to that effect has been
introduced in the past. It is not possible to determine whether such legislation
will be reintroduced or enacted, and, if enacted, whether it would apply to a
recapitalization occurring prior to the date of enactment.
 
    The presence of such options may also affect the calculation of interest
income and OID, among other things. For purposes of determining the yield and
maturity of a Note, if the Company has an unconditional option or combination of
options to require payments to be made on the Note under an alternative payment
schedule or schedules (e.g., an option to extend or an option to call the Note
at a fixed premium), it will be deemed to exercise or not exercise an option or
combination of options in a manner that minimizes the yield on the Note.
Conversely, a holder having such option or combination of such options will be
deemed to exercise or not exercise such option or combination of options in a
manner that maximizes the yield on such Note. If both the Company and the holder
have options, the foregoing rules are applied to the options in the order that
they may be exercised. Thus, the deemed exercise of one option may eliminate
other options that are later in time. If the exercise of such option or options
actually occurs or does not occur, contrary to what is deemed to occur pursuant
to the foregoing rules, then, solely for purposes of the accrual of OID, the
yield and maturity of the Note are redetermined by treating the Note as reissued
on the date of the occurrence or non-occurrence of the exercise for an amount
equal to its adjusted issue price on that date. Depending on the terms of the
options described above, the presence of such options may instead cause the
Notes to be taxable as Contingent Notes under the 1996 OID Regulations. See
"Original Issue Discount--FLOATING RATE NOTES THAT ARE NOT VRDIS."
 
    THE FOREGOING DISCUSSION OF EXTENDIBLE NOTES, RENEWABLE NOTES AND RESET
NOTES IS PROVIDED FOR GENERAL INFORMATION ONLY. ADDITIONAL TAX CONSIDERATIONS
MAY ARISE FROM THE OWNERSHIP OF SUCH NOTES IN LIGHT OF THE PARTICULAR FEATURES
OR COMBINATION OF FEATURES OF SUCH NOTES AND, ACCORDINGLY, PERSONS CONSIDERING
THE PURCHASE OF SUCH NOTES ARE ADVISED AND EXPECTED TO CONSULT WITH THEIR OWN
LEGAL AND TAX ADVISERS REGARDING THE TAX CONSEQUENCES OF THE OWNERSHIP OF SUCH
NOTES.
 
INTEGRATION OF NOTES WITH OTHER FINANCIAL INSTRUMENTS
 
    Any United States Holder of Notes that also acquires or has acquired any
financial instrument which, in combination with such Notes, would permit the
calculation of a single yield to maturity or could generally constitute a VRDI
of an equivalent term, may in certain circumstances treat such Notes and such
 
                                       35
<PAGE>
financial instrument as an integrated debt instrument for purposes of the Code,
with a single determination of issue price and the character and timing of
income, deductions, gains and losses. (For purposes of determining OID, none of
the payments under the integrated debt instrument will be treated as qualified
stated interest.) Moreover, under the 1996 OID Regulations, the IRS may require
in certain circumstances that a United States Holder who owns Notes integrate
such Notes with a financial instrument held or acquired by such Holder or a
related party. United States Holders should consult their tax advisors as to
such possible integration.
 
SALE OR EXCHANGE OF NOTES
 
    A United States Holder generally will recognize gain or loss upon the sale
or exchange of a Note equal to the difference between the amount realized upon
such sale or exchange and the United States Holder's adjusted basis in the Note.
Such adjusted basis in the Note generally will equal the cost of the Note,
increased by OID, acquisition discount or market discount previously included in
respect thereof, and reduced (but not below zero) by any payments on the Note
other than payments of qualified stated interest and by any premium that the
United States Holder has taken into account. To the extent attributable to
accrued but unpaid qualified stated interest, the amount realized by the United
States Holder will be treated as a payment of interest. Generally, any gain or
loss will be capital gain or loss if the Note was held as a capital asset,
except as provided under "Market Discount," "Short-Term Notes" and "Original
Issue Discount--FLOATING RATE NOTES THAT ARE NOT VRDIS," above. Special rules
apply in determining the tax basis of a Contingent Note and the amount realized
on the retirement of a Contingent Note. The excess of net long-term capital
gains over net short-term capital losses is taxed at a lower rate than ordinary
income for certain non-corporate taxpayers. The distinction between capital gain
or loss and ordinary income or loss is also relevant for purposes of, among
other things, limitations on the deductibility of capital losses.
 
FOREIGN HOLDERS
 
    As used herein, the term "Non-United States Holder" means a holder of a Note
that is, for United States federal income tax purposes, (i) a nonresident alien
individual, (ii) a foreign corporation, (iii) a nonresident alien fiduciary of a
foreign estate or trust or (iv) a foreign partnership one or more of the members
of which is, for United States federal income tax purposes, a nonresident alien
individual, a foreign corporation or a nonresident alien fiduciary of a foreign
estate or trust.
 
    On April 15, 1996, proposed Treasury Regulations (the "1996 Proposed
Regulations") were issued which, if adopted in final form, could affect the
United States taxation of Non-United States Holders. The 1996 Proposed
Regulations are generally proposed to be effective for payments after December
31, 1997, regardless of the issue date of the Note with respect to which such
payments are made, subject to certain transition rules. It cannot be predicted
at this time whether the 1996 Proposed Regulations will become effective as
proposed or what, if any, modifications may be made to them. The discussion
under this heading and under "Backup Withholding and Information Reporting,"
below, is not intended to include a complete discussion of the provisions of the
1996 Proposed Regulations, and prospective investors are urged to consult their
tax advisors with respect to the effect the 1996 Proposed Regulations may have
if adopted.
 
    Under current United States federal income tax law now in effect, and
subject to the discussion of backup withholding in the following section,
payments of principal and interest (including OID) with respect to a Note by the
Company or by any paying agent to any Non-United States Holder will not be
subject to the withholding of United States federal income tax, provided, in the
case of interest (including OID), that (i) such Holder does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of the Company entitled to vote, (ii) such Holder is not for federal
income tax purposes a controlled foreign corporation related, directly or
indirectly, to the Company
 
                                       36
<PAGE>
through stock ownership, (iii) such Holder is not a bank receiving interest
described in Section 881(c)(3)(A) of the Code and (iv) either (A) the beneficial
owner of the Note certifies, under penalties of perjury, to the Company or
paying agent, as the case may be, that such Holder is a Non-United States Holder
and provides such Holder's name and address, or (B) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "financial
institution") and holds the Note, certifies, under penalties of perjury, to the
Company or paying agent, as the case may be, that such certificate has been
received from the beneficial owner by it or by a financial institution between
it and the beneficial owner and furnishes the payor with a copy thereof. A
certificate described in this paragraph is effective only with respect to
payments of interest (including OID) made to the certifying Non-United States
Holder after the issuance of the certificate in the calendar year of its
issuance and the two immediately succeeding calendar years. Under temporary
Treasury Regulations, the foregoing certification may be provided by the
beneficial owner of a Note on IRS Form W-8.
 
    The 1996 Proposed Regulations provide optional documentation procedures
designed to simplify compliance by withholding agents. The 1996 Proposed
Regulations would not affect the documentation rules described above, but would
add "intermediary certification" options for certain qualifying withholding
agents. Under one such option, a withholding agent would be allowed to rely on
IRS Form W-8 furnished by a financial institution or other intermediary on
behalf of one or more beneficial owners (or other intermediaries) without having
to obtain the beneficial owner certificate described in the preceding paragraph,
provided that the financial institution or intermediary has entered into a
withholding agreement with the IRS and thus is a "qualified intermediary." Under
another option, an authorized foreign agent of the U.S. withholding agent would
be permitted to act on behalf of the U.S. withholding agent, provided certain
conditions are met.
 
    For purposes of establishing entitlement to the withholding exemption
described above, the 1996 Proposed Regulations generally would, if adopted,
treat as the beneficial owners of payments on a Note those persons that, under
United States tax principles, are the taxpayers with respect to such payments.
For example, the partners of a foreign partnership, rather than the partnership
itself, would be required to provide the required certifications to qualify for
such withholding exemption. Thus, subject to certain exceptions, each partner,
rather than the partnership, would be required to provide the required
certifications to qualify for the withholding exemption described above.
 
    The 1996 Proposed Regulations provide certain presumptions with respect to
withholding for holders not providing the required certifications to qualify for
the withholding exemption described above. In addition, the 1996 Proposed
Regulations would replace a number of current tax certification forms (including
IRS Form W-8 and IRS Form 4224, discussed below) with a single, restated form
(and, in certain circumstances, additional information) and standardize the
period of time for which withholding agents could rely on such certifications.
 
    Notwithstanding the foregoing, interest described in Section 871(h)(4) of
the Code will be subject to United States withholding tax at a 30% rate (or such
lower rate as may be provided by an applicable treaty). In general, interest
described in Section 871(h)(4) of the Code includes (subject to certain
exceptions) any interest the amount of which is determined by reference to
receipts, sales or other cash flow of the issuer or a related person, any income
or profits of the issuer or a related person, any change in the value of any
property of the issuer or a related person or any dividends, partnership
distribution or similar payments made by the issuer or a related person.
Interest described in Section 871(h)(4) of the Code may include other types of
contingent interest identified by the IRS in future Treasury Regulations.
 
    If a Non-United States Holder is engaged in a trade or business in the
United States and interest (including OID) on the Note is effectively connected
with the conduct of such trade or business, the Non-United States Holder,
although exempt from the withholding tax discussed above, will be subject to
United States federal income tax on such interest (including OID) in the same
manner as if it were a United States
 
                                       37
<PAGE>
Holder. In lieu of the certificate described above, such Holder will be required
to provide a properly executed IRS Form 4224 in order to claim an exemption from
withholding tax. In addition, if such Holder is a foreign corporation, it may be
subject to a branch profits tax equal to 30% (or such lower rate as may be
specified by an applicable treaty) of its effectively connected earnings and
profits for the taxable year, subject to adjustments. For this purpose, interest
(including OID) on a Note will be included in the earnings and profits of such
Holder if such interest (including OID) is effectively connected with the
conduct by such Holder of a trade or business in the United States.
 
    Generally, any gain or income (other than that attributable to accrued
interest or OID) realized upon the sale, exchange, retirement or other
disposition of a Note will not be subject to United States federal income tax
unless (i) such gain or income is effectively connected with a trade or business
in the United States of the Non-United States Holder or (ii) in the case of a
Non-United States Holder who is a nonresident alien individual, the Non-United
States Holder is present in the United States for 183 days or more in the
taxable year of such sale, exchange, retirement or other disposition and either
(a) such individual has a "tax home" (as defined in Section 911(d)(3) of the
Code) in the United States or (b) the gain is attributable to an office or other
fixed place of business maintained by such individual in the United States.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    Under current United States federal income tax law, information reporting
requirements apply to interest (including OID) and principal payments made to,
and to the proceeds of sales before maturity by, certain non-corporate United
States Holders. In addition, a 31% backup withholding tax will apply if the
non-corporate United States Holder (i) fails to furnish such holder's Taxpayer
Identification Number ("TIN") (which, for an individual, would be his or her
Social Security Number) to the payor in the manner required, (ii) furnishes an
incorrect TIN and the payor is so notified by the IRS, (iii) is notified by the
IRS that it has failed properly to report payments of interest and dividends or
(iv) in certain circumstances, fails to certify, under penalties of perjury,
that it has not been notified by the IRS that it is subject to backup
withholding for failure properly to report interest and dividend payments.
Backup withholding will not apply with respect to payments made to certain
exempt recipients, including corporations, tax-exempt organizations, qualified
pension and profit-sharing trusts and individual retirement accounts, provided
that they establish entitlement to an exemption.
 
    In the case of a Non-United States Holder, under Treasury Regulations,
backup withholding and information reporting will not apply to payments of
principal and interest made by the Company or any paying agent thereof on a Note
with respect to which such holder has provided the required certification under
penalties of perjury that it is a Non-United States Holder or has otherwise
established an exemption, provided that (i) the Company or paying agent, as the
case may be, does not have actual knowledge that the payee is a United States
person and (ii) certain other conditions are satisfied.
 
    In general, (i) principal or interest payments on a Note collected outside
the United States by a foreign office of a custodian, nominee or other agent
acting on behalf of a beneficial owner of a Note and (ii) payments on the sale,
exchange or retirement of a Note to or through a foreign office of a broker are
not subject to backup withholding or information reporting. However, if such
custodian, nominee, agent or broker is a United States person, a controlled
foreign corporation for United States tax purposes, or a foreign person 50% or
more of whose gross income is effectively connected with the conduct of a United
States trade or business for a specified three-year period, such custodian,
nominee, agent or broker may be subject to certain information reporting (but
not backup withholding) requirements with respect to such payments unless such
custodian, nominee, agent or broker has in its records documentary evidence that
the beneficial owner is not a United States person and certain conditions are
met or the beneficial owner otherwise establishes an exemption.
 
                                       38
<PAGE>
    The 1996 Proposed Regulations would, if adopted, alter the foregoing rules
in certain respects. In particular, the 1996 Proposed Regulations would require
backup withholding in the event that the custodian, nominee, agent or broker has
actual knowledge that the beneficial owner is a United States person.
 
    Backup withholding tax is not an additional tax. Rather, any amounts
withheld from a payment to a holder under the backup withholding rules will be
allowed as a refund or a credit against such holder's United States federal
income tax, provided that the required information is furnished to the IRS.
 
    Holders should consult their tax advisors regarding the application of
information reporting and backup withholding to their particular situations, the
availability of an exemption therefrom, and the procedure for obtaining such an
exemption, if available.
 
                              PLAN OF DISTRIBUTION
 
    The Company may sell the Notes in and/or outside the United States: (i)
through underwriters or dealers; (ii) directly to a limited number of purchasers
or to a single purchaser; or (iii) through agents. The Prospectus Supplement
with respect to the Notes being offered (the "Offered Notes") will set forth the
terms of the offering of the Offered Notes, including the name or names of any
underwriters or agents, the purchase price of the Offered Notes and the proceeds
to the Company from such sale, any underwriting discounts and other items
constituting underwriters' compensation, any initial public offering price and
any discounts or concessions allowed or reallowed or paid to dealers. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
    If underwriters are used in the sale, the Offered Notes will be acquired by
the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The Notes
may be offered to the public either through underwriting syndicates represented
by one or more managing underwriters or directly by one or more underwriters.
The underwriter or underwriters with respect to a particular underwritten
offering of Notes, or, if an underwriting syndicate is used, the managing
underwriter or underwriters, will be set forth on the cover of the applicable
Prospectus Supplement. Unless otherwise set forth in the Prospectus Supplement
relating thereto, the obligations of the underwriters to purchase the Offered
Notes will be subject to conditions precedent and the underwriters will be
obligated to purchase all of the Offered Notes if any are purchased.
 
    If dealers are utilized in the sale of Offered Notes in respect of which
this Prospectus is delivered, and if so specified in the applicable Prospectus
Supplement, the Company will sell such Offered Notes to the dealers as
principals. The dealers may then resell such Offered Notes to the public at
varying prices to be determined by such dealers at the time of resale. The names
of the dealers and the terms of the transaction will be set forth in the
applicable Prospectus Supplement.
 
    The Notes may be sold directly by the Company or through agents designated
by the Company from time to time. Any agent involved in the offer or sale of the
Offered Notes in respect to which this Prospectus is delivered will be named,
and any commissions payable by the Company to such agent will be set forth, in
the Prospectus Supplement.
 
    Underwriters, dealers and agents may be entitled under agreements entered
into with the Company to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act, or to contribution
with respect to payments which the underwriters, dealers or agents may be
required to make in respect thereof. Underwriters, dealers and agents may be
customers of, may engage in transactions with, or perform services for, the
Company in the ordinary course of business.

    The    % Preferred Securities, Series A (the "Series A Preferred
Securities") offered hereby are being issued by and represent undivided
preferred beneficial interests in the assets of MidAmerican Energy Financing I,
a statutory business trust formed under the laws of the State of Delaware (the
"Series A Issuer" or the "Series A Trust"). The preferred interests represented
by the Series A Preferred Securities will have a preference under certain
circumstances with respect to cash distributions and amounts payable on
liquidation, redemption or otherwise over the trust interests represented by the
Series A Common Securities (as defined herein) issued by the Series A Issuer.
See "Description of the Preferred Securities -- Subordination of Common
Securities" in the accompanying Prospectus.
 
    MidAmerican Energy Company, an Iowa corporation ("MidAmerican Energy" or the
"Company"), is the owner of the trust interests represented by the common
securities (the "Series A Common Securities" and together with the Series A
Preferred Securities the "Series A Trust Securities") issued by the Series A
Issuer. The Series A Issuer exists for the sole purpose of issuing its trust
interests and investing the proceeds thereof in the    % Junior Subordinated
Debentures, Series A (the "Series A Debentures") issued by MidAmerican Energy.
The Series A Debentures will mature on              , 20  , which date may be
extended to a date not later than              , 20  if certain conditions are
met. See "Certain Terms of the Series A Debentures--General". MidAmerican Energy
has the right to, at any time, cause the termination of the Series A Issuer and
the distribution of the Series A Debentures to the Holders of the Series A Trust
Securities on a pro rata basis in liquidation of such Holders' interests in the
Trust. See "Certain Terms of the Series A Preferred Securities -- Termination of
the Series A Issuer and Distribution of the Series A Debentures". The First
National Bank of Chicago is the Property Trustee of the Series A Issuer and the
Indenture Trustee and Guarantee Trustee of MidAmerican Energy.

    several Underwriters against certain liabilities, including liabilities
    under the Securities Act of 1933, as amended. See "Underwriting".
 
(2) In view of the fact that the entire proceeds of the sale of the Series A
    Preferred Securities will be used to purchase the Series A Debentures, the
    Underwriting Agreement provides that MidAmerican Energy will pay to the
    Underwriters, as compensation for their arranging the investment therein of

    The Series A Preferred Securities offered hereby are offered severally by
the Underwriters, as specified herein, subject to receipt and acceptance by them
and subject to their right to reject any order in whole or in part. It is
expected that the Series A Preferred Securities will be ready for delivery in
book-entry form only through the facilities of The Depository Trust Company on
or about              , 1996, against payment therefor in immediately available
funds.
 
                            [NAMES OF UNDERWRITERS]
                                  -----------
 
         The date of this Prospectus Supplement is             , 1996.

(COVER CONTINUED)
 
    Registered owners (the "Holders") of the Series A Preferred Securities will
be entitled to receive preferential cumulative cash distributions accruing from
the date of original issuance and payable quarterly in arrears on the first day
of March, June, September and December of each year, commencing             , at
the per annum rate of        % of the liquidation preference amount of $25 per
Series A Preferred Security (together, at any given time, with any accrued but
unpaid such amounts and interest thereon, if any, "Distributions"). Interest on
the Series A Debentures is the sole source of income for the Series A Issuer
from which payment of Distributions on the Series A Preferred Securities can be
made.
 
    MidAmerican Energy has the right to defer payments of interest on the Series
A Debentures by extending the interest payment period thereon at any time or
from time to time for up to 20 consecutive quarters with respect to each
deferral period (each, an "Extension Period"), provided that any such Extension
Period may not extend beyond the maturity of the Series A Debentures and that
MidAmerican Energy may not defer any payment of Additional Interest Attributable
to Taxes (as defined in the accompanying Prospectus). If interest payments on
the Series A Debentures are deferred, Distributions on the Series A Preferred
Securities will also be deferred. During an Extension Period, quarterly
Distributions on the Series A Preferred Securities will continue to accrue and
Distributions that are in arrears will bear interest on the amount thereof at
the per annum rate of [      ]% (to the extent permitted by applicable law,
compounded quarterly), and Holders of Series A Preferred Securities will be
required to accrue income for United States federal income tax purposes. See
"Description of the Series A Debentures -- Option to Extend Interest Payment
Period" and "United States Federal Income Taxation -- Original Issue Discount."
Upon the termination of any Extension Period and the payment of all amounts then
due, including interest on deferred interest payments, MidAmerican Energy may
select a new Extension Period, subject to the above requirements.
 
    The payment of Distributions and payments on liquidation of the Series A
Issuer or the redemption of Series A Preferred Securities, in each case out of
moneys held by the Series A Issuer as set forth below, are guaranteed by
MidAmerican Energy to the extent the Series A Issuer has sufficient funds
available to make such payments (the "Series A Guarantee"). See "Certain Terms
of the Series A Guarantee." If MidAmerican Energy fails to make interest
payments on the Series A Debentures held by the Series A Issuer, the Series A
Issuer will have insufficient funds to pay Distributions on the Series A
Preferred Securities. The Series A Guarantee does not cover payment of
Distributions when the Series A Issuer does not have sufficient funds to pay
such Distributions. In such event, a Holder of Series A Preferred Securities
will have the right to institute a suit directly against MidAmerican Energy to
enforce payment of principal of or interest on the Series A Debentures. See
"Description of the Debentures-- Enforcement of Certain Rights by Holders of
Preferred Securities" in the accompanying Prospectus. MidAmerican Energy's
obligations under the Series A Guarantee are subordinate and junior in right of
payment to Senior Indebtedness (as defined in the accompanying Prospectus) of
MidAmerican Energy except any liabilities that may be made PARI PASSU expressly
by their terms. MidAmerican Energy has agreed in an Agreement as to Expenses and
Liabilities (the "Expense Agreement") to provide funds to the Series A Issuer as
needed to pay obligations of the Series A Issuer to parties other than Holders
of Series A Trust Securities. The Series A Debentures and the Series A
Guarantee, together with the obligations of MidAmerican Energy with respect to
the Series A Preferred Securities under the Indenture, the Series A Supplemental
Indenture (as defined herein), the Trust Agreement (as defined herein) and the
Expense Agreement constitute a full and unconditional guarantee of the Series A
Preferred Securities by MidAmerican Energy.
 
    The Series A Preferred Securities are subject to mandatory redemption upon
repayment of the Series A Debentures at maturity or upon their earlier
redemption. See "Description of the Preferred Securities--Redemption Procedures"
in the accompanying Prospectus. MidAmerican Energy will have the option at any
time on or after          , to redeem the Series A Debentures, in whole or in
part. MidAmerican Energy also will have the option, upon the occurrence and
during the continuation of a Special Event (as defined herein), to redeem at any
time the Series A Debentures, in whole but not in part, which will result in the
redemption of all the Series A Trust Securities by the Series A Issuer. Any
redemption of Series A Trust Securities by the Series A Issuer will be in
amounts having an aggregate liquidation preference amount equal to the aggregate
principal of Series A Debentures to be redeemed and will be at a redemption
price equal to 100% of such liquidation preference amount, plus accrued and
unpaid Distributions, if any, to the redemption date. Each class of the Series A
Trust Securities will be redeemed in
 
                                      S-2
<PAGE>
proportion to the percentage they represent of all the Series A Trust
Securities. See "Description of the Debentures -- Optional Redemption" in the
accompanying Prospectus.
 
    MidAmerican Energy will have the right, at any time, to cause the
termination of the Series A Issuer and, in connection therewith, after
satisfaction of creditors of the Series A Issuer, if any, to cause the
distribution of Series A Debentures to the Holders of Series A Preferred
Securities and the Common Securities in liquidation of the Series A Issuer. See
"Certain Terms of the Series A Preferred Securities--Termination of Series A
Issuer and Distribution of Series A Debentures".
 
    The Series A Debentures and the obligations of MidAmerican Energy under the
Guarantee are subordinate and junior in right of payment to all Senior
Indebtedness (as defined in the accompanying Prospectus) of MidAmerican Energy.
The terms of the Series A Debentures place no limitation on the amount of Senior
Indebtedness that may be incurred by MidAmerican Energy. As of            ,
    , MidAmerican Energy had approximately $  million of principal amount of
indebtedness for borrowed money and capital lease obligations constituting
Senior Indebtedness. See "Description of the Debentures -- Subordination" and
"Description of the Preferred Securities" in the accompanying Prospectus.
 
    In the event of the liquidation of the Series A Issuer, the Holders of the
Series A Trust Securities will be entitled to receive either (i) Series A
Debentures in an aggregate principal amount of $25 per Series A Preferred
Security or (ii) a liquidation preference amount of $25 per Series A Preferred
Security, plus accrued and unpaid Distributions thereon to the date of payment,
subject to certain limitations. See Description of the "Preferred Securities --
Liquidation Distribution upon Termination" in the accompanying Prospectus.
 
    Trading of the Series A Preferred Securities on the NYSE is expected to
commence within 30 days after the initial delivery of the Series A Preferred
Securities. If the Series A Debentures are distributed to the holders of Series
A Preferred Securities upon the liquidation of the Series A Issuer, MidAmerican
Energy will use its best efforts to list the Series A Debentures on the NYSE or
such other stock exchanges, if any, on which the Series A Preferred Securities
are then listed.
 
    The Series A Preferred Securities will be represented by a global
certificate registered in the name of The Depository Trust Company ("DTC") or
its nominee. Beneficial interests in the Series A Preferred Securities will be
shown on, and transfers thereof will be effected only through, records
maintained by Participants (as defined in the accompanying Prospectus) in DTC.
Except as described herein, Series A Preferred Securities in certificated form
will not be issued in exchange for the global certificate. See "Description of
the Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company" in the accompanying Prospectus.
 
    IN CONNECTION WITH THIS OFFERING, THE UNDERWRITERS MAY OVER-ALLOT OR EFFECT
TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE SERIES A
PREFERRED SECURITIES OFFERED HEREBY AT LEVELS ABOVE THOSE WHICH MIGHT OTHERWISE
PREVAIL IN THE OPEN MARKET. SUCH TRANSACTIONS MAY BE EFFECTED ON THE NEW YORK
STOCK EXCHANGE, IN THE OVER-THE-COUNTER MARKET OR OTHERWISE. SUCH STABILIZING,
IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME.

                                  RISK FACTORS
 
    Prospective purchasers of Series A Preferred Securities should carefully
review the information contained elsewhere herein and should particularly
consider the following risk factors with respect to the Series A Preferred
Securities:
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE SERIES A GUARANTEE AND THE SERIES
  A DEBENTURES
 
    MidAmerican Energy's obligations under the Series A Guarantee issued by
MidAmerican Energy for the benefit of the Holders of the Series A Preferred
Securities are unsecured and rank subordinate and junior in right of payment to
Senior Indebtedness of MidAmerican Energy, except any liabilities that may be
made PARI PASSU expressly by their terms. The obligations of MidAmerican Energy
under the Series A Debentures are subordinate and junior in right of payment to
Senior Indebtedness of MidAmerican Energy. As of               , 1996,
MidAmerican Energy had approximately $     billion principal amount of Senior
Indebtedness. There are no terms of the Series A Preferred Securities, the
Series A Debentures or the Series A Guarantee that limit MidAmerican Energy's
ability to incur additional indebtedness, including indebtedness that would rank
senior to the Series A Debentures and the Series A Guarantee. See "Description
of the Guarantee -- Status of the Guarantee" and "Description of the Debentures
- -- Subordination" in the accompanying Prospectus.
 
    The ability of the Series A Issuer to pay amounts due on the Series A
Preferred Securities is solely dependent upon MidAmerican Energy making payments
on the Series A Debentures as and when required.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
 
    MidAmerican Energy has the right under the Indenture to extend the interest
payment period at any time and from time to time on the Series A Debentures, for
a period not exceeding 20 consecutive quarters. As a consequence of any such
extension, quarterly Distributions on the Series A Preferred Securities would be
deferred by the Series A Issuer during such Extension Period, but would continue
to accumulate additional Distributions thereon at the rate of    % per annum. In
the event that MidAmerican Energy exercises this right, during any Extension
Period MidAmerican Energy may not and may not permit any of its subsidiaries to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of MidAmerican
Energy's capital stock or (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of
MidAmerican Energy (including other debentures issued pursuant to the Indenture
(as defined in the accompanying Prospectus)) that rank PARI PASSU with or junior
in interest to the Series A Debentures or make any guarantee payments with
respect to any guarantee by MidAmerican Energy of the debt securities of any of
its subsidiaries if such guarantee ranks PARI PASSU with or junior in interest
to the Series A Debentures (other than (a) dividends or distributions in Common
Stock of MidAmerican Energy, (b) payments under any Guarantee (as defined in the
accompanying Prospectus), and (c) purchases of common stock related to the
issuance of common stock under any of MidAmerican Energy's benefit plans for its
directors, officers or employees). Prior to the termination of any such
Extension Period, MidAmerican Energy may further extend the interest payment
period, provided that such Extension Period together with all such previous and
further extensions thereof may not exceed 20 consecutive quarters and that such
Extension Period may not extend beyond the maturity date of the Series A
Debentures. Upon the termination of any Extension Period and the payment of all
amounts then due on any Interest Payment Date, MidAmerican Energy may elect to
begin a new Extension Period subject to the above requirements. Consequently,
there could be multiple Extension Periods of varying lengths throughout the term
of the Series A Debentures. See "Certain Terms of the Series A Preferred
Securities--Distributions" and "Certain Terms of the Series A Debentures--Option
to Extend Interest Payment Period."
 
                                      S-4
<PAGE>
    Because MidAmerican Energy has the right to extend the interest payment
period on the Series A Debentures, the Series A Debentures will be treated as
having been issued with original issue discount ("OID") for United States
federal income tax purposes. As a result, Holders of Series A Preferred
Securities will be required to include in their gross income Distributions as
they accrue, rather than when they are paid, regardless of the Holder's regular
method of accounting. OID on the Series A Preferred Securities will be treated
as interest and, except with respect to an Extension Period, will generally be
equal to the Distributions on the Series A Preferred Securities each year.
Should an Extension Period occur, a Holder of Series A Preferred Securities will
continue to accrue interest (in the form of OID) in income in respect of its pro
rata share of the Series A Debentures held by the Series A Issuer for United
States federal income tax purposes. As a result, a Holder of Series A Preferred
Securities will include such interest in gross income for United States federal
income tax purposes in advance of the receipt of cash, and will not receive the
cash related to such income from the Series A Issuer if the Holder disposes of
the Series A Preferred Securities prior to the record date for the payment of
Distributions. See "United States Federal Income Taxation--Original Issue
Discount."
 
    MidAmerican Energy has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Series A
Debentures. However, should MidAmerican Energy elect to exercise such right in
the future, the market price of the Series A Preferred Securities is likely to
be affected. A Holder that disposes of its Series A Preferred Securities during
an Extension Period, therefore, might not receive the same return on its
investment as a Holder that continues to hold its Series A Preferred Securities.
In addition, as a result of the existence of MidAmerican Energy's right to defer
interest payments, the market price of the Series A Preferred Securities (which
represent a preferred undivided beneficial interest in the Series A Debentures)
may be more volatile than other securities on which OID accrues and which do not
contain such rights.
 
TERMINATION OF SERIES A ISSUER AND DISTRIBUTION OF SERIES A DEBENTURES
 
    MidAmerican Energy has the right to, at any time, direct the Property
Trustee to dissolve the Series A Issuer and, in connection therewith, after
satisfaction of creditors of the Series A Issuer, if any, cause the Series A
Debentures to be distributed to the Holders of Series A Trust Securities on a
pro rata basis in liquidation of such Holders' interests in the Trust. Under
current United States federal income tax law, a distribution of Series A
Debentures upon the termination and dissolution of the Series A Issuer would not
be a taxable event to holders of the Series A Preferred Securities. See "United
States Federal Income Taxation--Receipt of Series A Debentures or Cash Upon
Liquidation of the Series A Trust." Because Holders of Series A Preferred
Securities may receive Series A Debentures, prospective purchasers of Series A
Preferred Securities are also making an investment decision with regard to the
Series A Debentures and should carefully review all the information regarding
the Series A Debentures contained herein. See "Description of the Series A
Preferred Securities--Termination of Series A Issuer and Distribution of Series
A Debentures" herein and "Description of the Series A Debentures--General" in
the accompanying Prospectus.
 
MARKET PRICE
 
    There can be no assurance as to the market prices for Series A Preferred
Securities or Series A Debentures that may be distributed in exchange for Series
A Preferred Securities if the Series A Issuer were to be terminated and
dissolved. Accordingly, the Series A Preferred Securities that an investor may
purchase, whether pursuant to the offer made hereby or in the secondary market,
or the Series A Debentures that a Holder of Series A Preferred Securities may
receive on termination and liquidation of the Series A Issuer, may trade at a
discount to the price that the investor paid to purchase the Series A Preferred
Securities offered hereby.
 
                                      S-5
<PAGE>
SPECIAL EVENT REDEMPTION
 
    Upon the occurrence and continuation of a Special Event, MidAmerican Energy
has the right to redeem the Series A Debentures, in whole but not in part, and
therefore cause a mandatory redemption of all the Series A Preferred Securities
and Series A Common Securities within 90 days following the occurrence of such
Special Event. See "Certain Terms of the Series A Preferred Securities--Special
Event Redemption." The receipt of cash by the holders of the Series A Preferred
Securities upon a dissolution of the Series A Trust would be a taxable event to
such holders. See "United States Federal Income Taxation--Receipt of Series A
Debentures or Cash Upon Liquidation of the Series A Trust."
 
POSSIBLE TAX LAW CHANGES
 
    On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill") was
released, which would, among other things, generally deny interest deductions
for interest on an instrument, issued by a corporation, that has a maximum
weighted average maturity of more than 40 years. The Bill would also generally
deny interest deductions for interest on an instrument, issued by a corporation,
that has a maximum term of more than 20 years and that is not shown as
indebtedness on the separate balance sheet of the issuer or, where the
instrument is issued to a related party (other than a corporation), where the
holder or some other related party issues a related instrument that is not shown
as indebtedness on the issuer's consolidated balance sheet. The above-described
provisions of the Bill were proposed to be effective generally for debt
instruments issued on or after December 7, 1995. If either of such provisions
were to apply to the Series A Debentures, the Company would be unable to deduct
interest on the Series A Debentures. However, on March 29, 1996, the Chairmen of
the Senate Finance and House Ways and Means Committees issued a joint statement
to the effect that it was their intention that the effective date of the
President's legislative proposals, if adopted, will be no earlier than the date
of appropriate Congressional action. The Company believes that, under current
law, it will be able to deduct interest on the Series A Debentures. There can be
no assurance, however, that current or future legislative proposals or final
legislation will not affect the ability of the Company to deduct interest on the
Series A Debentures. Such a change could give rise to a Tax Event (as
hereinafter defined), which may permit the Company to cause a redemption of the
Series A Preferred Securities. See "Certain Terms of the Series Preferred A
Securities--Special Event Redemption" and "United States Federal Income
Taxation-- Possible Tax Law Changes."
 
RIGHTS UNDER THE GUARANTEE; LIMITATION AS TO FUNDS AVAILABLE TO THE SERIES A
  ISSUER
 
    The Series A Guarantee will be qualified as an indenture under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The First
National Bank of Chicago will act as indenture trustee under the Series A
Guarantee for the purposes of compliance with the Trust Indenture Act (the
"Series A Guarantee Trustee") and will hold the Guarantee for the benefit of the
Holders of the Series A Preferred Securities. The First National Bank of Chicago
will also act as trustee for the Series A Debentures and as Property Trustee
under the Series A Trust Agreement (as defined herein) pursuant to which the
Series A Issuer has been formed.
 
    The Series A Guarantee guarantees to the Holders of the Series A Preferred
Securities to the extent not paid by the Series A Issuer, the payment (but not
the collection) of (i) any accrued and unpaid Distributions required to be paid
on the Series A Preferred Securities, to the extent the Series A Issuer has
funds available therefor, (ii) the redemption price, and all accrued and unpaid
distributions to the date of redemption, with respect to Series A Preferred
Securities called for redemption by the Series A Issuer, to the extent the
Series A Issuer has funds available therefor and (iii) upon a voluntary or
involuntary dissolution, winding-up or termination of the Series A Issuer
(unless the Series A Debentures are distributed to Holders of the Series A
Preferred Securities), the lesser of (a) the aggregate of the liquidation
preference amount and all accrued and unpaid Distributions on the Series A
Preferred
 
                                      S-6
<PAGE>
Securities to the date of payment and (b) the amount of assets of the Series A
Issuer remaining available for distribution to Holders of the Series A Preferred
Securities in liquidation of the Series A Issuer. The Holders of not less than a
majority in aggregate liquidation preference amount of the Series A Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Series A Guarantee Trustee or to
direct the exercise of any trust power conferred upon the Series A Guarantee
Trustee under the Series A Guarantee. Any Holder of Series A Preferred
Securities may institute a legal proceeding directly against MidAmerican Energy
to enforce its rights under the Series A Guarantee without first instituting a
legal proceeding against the Series A Issuer, the Guarantee Trustee or any other
person or entity. If MidAmerican Energy were to default on its obligations under
the Series A Debentures, the Series A Issuer would lack available funds for the
payment of Distributions or amounts payable on redemption of the Series A
Preferred Securities or otherwise, and in such event Holders of the Series A
Preferred Securities would not be able to rely upon the Series A Guarantee for
payment of such amounts. Instead, Holders of Series A Preferred Securities would
have the limited enforcement rights described under "Description of Preferred
Securities--Events of Default; Notice" in the accompanying Prospectus. See
"Description of the Guarantees -- Status of the Guarantees" and "Description of
the Debentures -- Subordination" in the accompanying Prospectus. The Series A
Trust Agreement provides that each Holder of Series A Preferred Securities by
acceptance thereof agrees to the provisions of the Series A Guarantee and the
Indenture (as defined in the accompanying Prospectus).
 
LIMITED VOTING RIGHTS
 
    Holders of Series A Preferred Securities will generally have limited voting
rights relating only to the modification of the Series A Preferred Securities
and the dissolution, winding-up or termination of the Series A Issuer. Holders
of Series A Preferred Securities will not be entitled to vote to appoint, remove
or replace the Property Trustee or the Delaware Trustee under the Series Trust
Agreement, which voting rights are vested exclusively in the Holder of the
Common Securities except upon the occurrence of certain events. The
Administrative Trustees under the Series A Trust Agreement and MidAmerican
Energy may amend the Series A Trust Agreement to ensure that the Series A Issuer
will be classified for United States federal income tax purposes as a grantor
trust without the consent of Holders, even if such action adversely affects the
interests of Holders. See "Description of the Preferred Securities -- Voting
Rights", "-- Amendments" and "-- Co-Trustees and Separate Property Trustees" in
the accompanying Prospectus.
 
TRADING CHARACTERISTICS OF SERIES A PREFERRED SECURITIES
 
    The Series A Preferred Securities constitute a new issue of securities with
no established trading market. While MidAmerican Energy will apply to list the
Series A Preferred Securities on the NYSE, a minimum of 400 beneficial holders
and 1,000,000 outstanding securities is required for listing a new class of
securities on the NYSE. Accordingly, no assurance can be given as to the
liquidity of or the development and maintenance of trading markets for the
Series A Preferred Securities. If approved for listing, the Series A Preferred
Securities may trade at a price that does not fully reflect the value of accrued
but unpaid interest with respect to the underlying Series A Debentures. A Holder
that disposes of Series A Preferred Securities between record dates for payments
of Distributions thereon will be required to include accrued but unpaid interest
on the Series A Debentures through the date of disposition in income as ordinary
income and to add such amount to such Holder's adjusted tax basis in such
Holder's pro rata share of the underlying Series A Debentures deemed disposed
of. To the extent the selling price is less than such Holder's adjusted tax
basis (which will include, in the form of OID, all accrued and unpaid interest),
such Holder will recognize a capital loss. Subject to certain limited
exceptions, capital losses cannot be applied to offset ordinary income for
United States federal income tax purposes. See "United States Federal Income
Taxation -- Original Issue Discount" and "-- Sales of Series A Preferred
Securities."

                         MIDAMERICAN ENERGY FINANCING I
 
    MidAmerican Energy Financing I is a statutory business trust formed under
the Delaware Business Trust Act pursuant to (i) a Trust Agreement executed by
MidAmerican Energy, as Depositor of the Series A Issuer, and the Property
Trustees referred to therein and (ii) the filing of a Certificate of Trust with
the Delaware Secretary of State on October 31, 1996. Such Trust Agreement will
be amended and restated in its entirety (as so amended and restated, the "Series
A Trust Agreement") substantially in the form filed as an exhibit to the
Registration Statement of which this Prospectus Supplement is a part. The Series
A Trust Agreement will be qualified as an indenture under the Trust Indenture
Act. The Series A Issuer exists for the exclusive purposes of (i) issuing the
Series A Preferred Securities and the Series A Common Securities representing
trust interests in the Series A Issuer, (ii) purchasing the Series A Debentures
with the Series A Common Securities and the proceeds from the sale of the Series
A Preferred Securities and (iii) engaging only in those other activities
necessary or incidental thereto.
 
    All of the Series A Common Securities will be owned by MidAmerican Energy.
The Series A Common Securities will rank PARI PASSU, and payments will be made
thereon pro rata, with the Series A Preferred Securities, except that upon the
occurrence and continuance of a default under the Indenture, the rights of the
Holders of the Series A Common Securities to payment in respect of Distributions
and payments upon liquidation, redemption and otherwise will be subordinate to
the rights of the Holders of the Series A Preferred Securities. MidAmerican
Energy will acquire Series A Common Securities having an aggregate Liquidation
Amount (as defined in the accompanying Prospectus) equal to 3% of the total
capital of the Series A Issuer.
 
    The Series A Issuer will terminate on               unless earlier
terminated as provided in the Series A Trust Agreement. The Series A Issuer's
business and affairs will be conducted by the Administrative Trustees. The
duties and obligations of the Trustees shall be governed by the Series A Trust
Agreement. Philip G. Lindner, J. Sue Rozema and Paul J. Leighton, all officers
of MidAmerican Energy, will be appointed as Administrative Trustees pursuant to
the terms of the Series A Trust Agreement. Under the Series A Trust Agreement,
the Administrative Trustees will have certain duties and powers including, but
not limited to, the delivery of certain notices to the holders of the Series A
Preferred Securities, the appointment of the Paying Agent (as defined in the
accompanying Prospectus) and the Registrar (as defined in the accompanying
Prospectus) and the registering of transfers of the Series A Preferred
Securities. Under the Series A Trust Agreement, The First National Bank of
Chicago, as the Property Trustee, will have certain duties and powers including,
but not limited to, holding legal title to the Series A Debentures on behalf of
the Series A Trust, the collection of payments in respect of the Series A
Debentures, maintenance of the Payment Account (as defined in the Series A Trust
Agreement), the sending of default notices with respect to the Series A
Preferred Securities and the distribution of the assets of the Series A Trust in
the event of a winding up of the Series A Trust. See "Description of the
Preferred Securities" in the accompanying Prospectus.
 
    MidAmerican Energy has agreed to pay all fees and expenses related to the
Series A Issuer and the offering of the Series A Preferred Securities.

                           MIDAMERICAN ENERGY COMPANY
 
GENERAL
 
    MidAmerican Energy was formed on July 1, 1995 through the merger (the
"Merger") of Iowa-Illinois Gas and Electric Company ("Iowa-Illinois"), Midwest
Resources Inc. ("Midwest Resources") and Midwest Power Systems Inc. ("Midwest
Power") with and into MidAmerican. MidAmerican Energy is a combination electric
and natural gas public utility engaged in the generation, transmission,
distribution and sale of electric energy in Illinois, Iowa and South Dakota, and
the purchase, distribution, transportation and sale of natural gas in those
states and in the state of Nebraska. MidAmerican Energy's nonregulated
operations are conducted by its MidAmerican Capital Company ("MidAmerican
Capital") subsidiary; a separate wholly-owned subsidiary, Midwest Capital Group,
Inc. ("Midwest Capital"), functions as a regional business development company
in the utility service territory.
 
RECENT DEVELOPMENTS
 
    On April 24, 1996, MidAmerican Energy's shareholders approved a proposal to
form a holding company. The holding company will have three wholly-owned
subsidiaries consisting of MidAmerican Energy (utility operations), MidAmerican
Capital and Midwest Capital. The transaction is structured as a share exchange,
with each share of MidAmerican Energy common stock being exchanged for one share
of the holding company common stock. All regulatory approvals have been obtained
and it is management's intention to complete the formation of the holding
company on or about December 1, 1996.
 
    On May 28, 1996, MidAmerican Energy announced the restructuring of portions
of its nonregulated businesses. InterCoast Energy Company ("InterCoast") was
formed as an indirect subsidiary of MidAmerican Energy and a direct subsidiary
of MidAmerican Capital. InterCoast has operations in oil and gas, natural gas
marketing and wholesale electric power marketing and brokering. On October 17,
1996, MidAmerican Capital agreed to sell its subsidiaries which conduct oil and
gas and gas marketing operations to KCS Energy, Inc. for $174 million in cash,
$40 million in short term notes and warrants to acquire 610,000 shares of KCS
Energy, Inc. common stock for $45 per share.

(1) For purposes of computing the ratios of earnings to fixed charges,
    "earnings" consist of net income from continuing operations before interest
    charges and preferred dividend requirements, plus income taxes, plus the
    estimated interest component of rentals. "Earnings" also include allowances
    for borrowed and other funds used during construction. Fixed charges consist
    of interest charges and the estimated interest component of rentals.
 
(2) The supplemental ratios have been calculated including obligations of the
    Company under its long-term power purchase contract with the Nebraska Public
    Power District relating to Cooper Nuclear Station.
 
(3) Reflects the formation of the holding company and the transfer of
    MidAmerican Capital and Midwest Capital to the holding company by

                                USE OF PROCEEDS
 
    The Series A Issuer will use the proceeds from this offering of $   million
of Series A Preferred Securities, together with the issuance of the Series A
Common Securities, to purchase the Series A Debentures. MidAmerican Energy will
use the cash proceeds from the sale of the Series A Debentures net of the
Underwriters' Compensation and the other expenses of this offering, for the
repayment of a portion of its outstanding indebtedness and for general corporate
purposes. The Company has not yet selected the indebtedness to be repaid with
such net proceeds.
 
                              ACCOUNTING TREATMENT
 
    For financial reporting purposes, the Issuer will be treated as a subsidiary
of MidAmerican Energy and, accordingly, the accounts of the Issuer will be
included in the consolidated financial statements of MidAmerican Energy. The
Series A Preferred Securities will be presented as a separate line item in the
consolidated balance sheet of MidAmerican Energy and appropriate disclosures
about the Series A Preferred Securities, the Series A Guarantee and the Series A
Debentures will be included in the notes to the consolidated financial
statements. For financial reporting purposes, MidAmerican Energy will record
Distributions payable on the Series A Preferred Securities as an expense.

               CERTAIN TERMS OF THE SERIES A PREFERRED SECURITIES
 
GENERAL
 
    The following summary of certain terms and provisions of the Series A
Preferred Securities does not purport to be complete and is subject to, and
qualified in its entirety by reference to, the Series A Trust Agreement. The
form of the Series A Trust Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus Supplement and the accompanying
Prospectus are a part. See "Description of the Preferred Securities" in the
accompanying Prospectus.
 
DISTRIBUTIONS
 
    The Series A Preferred Securities represent preferred undivided beneficial
interests in the assets of the Series A Issuer, and the Distributions on each
Series A Preferred Security are payable at the rate set forth on the cover page
of this Prospectus Supplement, payable, except in the event of an extension,
quarterly in arrears on March 1, June 1, September 1 and December 1 of each
year. Distributions in arrears after the quarterly payment date therefor will
bear interest on the amount thereof at the same per annum rate (to the extent
permitted by law, compounded quarterly). The term "Distributions", as used
herein, includes interest payable on overdue Distributions, unless otherwise
stated. Distributions will accrue from the date of original issuance of the
Series A Preferred Securities. The amount of Distributions payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months
and, for any period shorter than a full month, shall be computed on the basis of
the actual number of days elapsed in such period.
 
    So long as no Event of Default under the Indenture has occurred and is
continuing, MidAmerican Energy has the right at any time and from time to time
to extend the interest payment period on the Series A Debentures for not more
than 20 consecutive quarters, provided that any such Extension Period shall not
extend beyond the maturity date or redemption date of the Series A Debentures
and that MidAmerican Energy may not defer any payment of Additional Interest
Attributable to Taxes (as defined in the accompanying Prospectus). During any
Extension Period quarterly distributions on the Series A Preferred Securities
would be deferred by the Series A Issuer and would continue to accrue, and
holders of Series A Preferred Securities would be required to accrue interest
income for United States Federal income tax purposes. See "Certain Terms of the
Series A Debentures -- Option to Extend Interest Payment Period" and "United
States Federal Income Taxation -- Original Issue Discount."
 
    MidAmerican Energy has no current intention of exercising its right to defer
payments of distributions on the Series A Preferred Securities by extending the
interest payment period on the Series A Debentures.
 
TERMINATION OF SERIES A ISSUER AND DISTRIBUTION OF SERIES A DEBENTURES
 
    MidAmerican Energy has the right to, at any time, direct the Property
Trustee to dissolve the Series A Issuer and, in connection therewith, after
satisfaction of creditors of the Series A Issuer, if any, cause the Series A
Debentures to be distributed to the Holders of Series A Trust Securities on a
pro rata basis in liquidation of such Holders' interests in the Trust. See
"Description of Preferred Securities -- Liquidation, Distribution Upon
Termination" in the accompanying Prospectus. If the Series A Debentures are
distributed to Holders of the Series A Preferred Securities as a result of the
termination of the Series A Issuer, the Company will use its best efforts to
list the Series A Preferred Securities on the NYSE or on such other exchange as
the Series A Preferred Securities are then listed.
 
    Under current United States Federal income tax law and interpretations, if
the Series A Issuer is treated as a grantor trust at the time of the
distribution, such a distribution should not be a taxable event to holders of
the Series A Preferred Securities. See "United States Taxation -- Receipt of
Series A Debentures or Cash Upon Liquidation of the Series A Trust."
 
                                      S-12
<PAGE>
REDEMPTION
 
    MidAmerican Energy has the right to redeem the Series A Debentures (a) on or
after       , 200 , in whole or in part, or (b) at any time, in whole but not in
part, upon the occurrence of a Tax Event or an Investment Company Event (each as
defined below, a "Special Event"), subject to the conditions described under "--
Special Event Redemption," below.
 
    Upon the repayment of the Series A Debentures, whether at maturity or upon
earlier redemption as provided in the Indenture, the proceeds from such payment
will be applied by the Property Trustee to redeem a Like Amount (as defined
below) of the Series A Common Securities and the Series A Preferred Securities,
upon not less than 30 nor more than 60 days' notice, at a redemption price equal
to the aggregate Liquidation Amount plus accumulated and unpaid distributions,
plus additional distributions thereon to the extent permitted by law, to the
Redemption Date. See "Certain Terms of the Series A Debentures -- Redemption."
 
    "Like Amount" means (i) with respect to a redemption of the Series A
Preferred Securities and the Series A Common Securities, Series A Trust
Securities having an aggregate Liquidation Amount (as hereinafter defined) equal
to the principal amount of Series A Debentures to be contemporaneously redeemed
in accordance with the Indenture and the proceeds of which shall be used to pay
the Redemption Price of such Series A Trust Securities and (ii) with respect to
a distribution of Series A Debentures to Holders of Series A Trust Securities in
connection with a termination or liquidation of the Series A Issuer, Series A
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Series A Trust Securities of the Holders to such Series A Debentures are
distributed.
 
SPECIAL EVENT REDEMPTION
 
    If a Special Event shall occur and be continuing with respect to the Series
A Issuer or the Series A Preferred Securities, MidAmerican Energy has the right
to redeem the Series A Debentures in whole (but not in part) and thereby cause a
mandatory redemption of the Series A Preferred Securities in whole (but not in
part) at a redemption price equal to the aggregate Liquidation Amount of such
Preferred Securities plus accumulated and unpaid distributions thereon within 90
days following the occurrence of such Special Event. In the event a Tax Event
has occurred and is continuing and MidAmerican Energy does not elect to
terminate the Series A Issuer (as described in "-- Termination of Series A
Issuer and Distribution of Series A Debentures") or redeem the Series A
Debentures (as described in the preceding sentence), the Series A Preferred
Securities will remain outstanding and Additional Interest Attributable to Taxes
(as defined in the accompanying Prospectus) will be payable on the Series A
Debentures.
 
    "Tax Event" means the receipt by the Series A Issuer of an opinion of
counsel (which may be counsel to MidAmerican Energy or an affiliate but not an
employee thereof and which must be acceptable to the Property Trustee)
experienced in such matters to the effect that, as a result of (a) any amendment
to, or change (including any announced prospective change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein affecting taxation, or (b) any amendment to,
or change in an interpretation or application of, such laws or regulations by
any legislative body, court, governmental agency or regulatory authority
(including the enactment of any legislation and the publication of any judicial
decision or regulatory determination on or after the date of issuance of the
Series A Preferred Securities), there is more than an insubstantial risk that
(i) the Series A Issuer is, or will be within 90 days of the date of such
opinion, subject to United States federal income tax with respect to interest
income received or accrued on the Series A Debentures, (ii) interest payable by
the Company on the Series A Debentures is not, or within 90 days of the date of
such opinion, will not be, deductible by the Company, in whole or in part, for
United States federal income tax purposes, or (iii) the Series A Issuer is, or
will be within 90 days of the date of such opinion, subject to more than a de
minimis amount of other taxes, duties or other governmental charges.
 
                                      S-13
<PAGE>
    "Investment Company Event" means the occurrence of a change in law or
regulation or a change in the interpretation or application of any law or
regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law") to the effect that the Series A Issuer is
or will be considered an "investment company" that is required to be registered
under the Investment Company Act of 1940, as amended, which Change in 1940 Act
Law becomes effective on or after the date of original issuance of the Series A
Preferred Securities.
 
LIQUIDATION AMOUNT
 
    The Liquidation Amount payable on the Series A Preferred Securities in the
event of any liquidation of the Series A Issuer is $25 per Series A Preferred
Security, plus accumulated and unpaid distributions unless, in connection with
such liquidation, the Series A Debentures are distributed to the holders of the
Series A Preferred Securities.
 
RIGHTS UNDER THE SERIES A GUARANTEE AND THE SERIES A DEBENTURES
 
    The Series A Guarantee will be a full unsecured guarantee with respect to
the Series A Preferred Securities from the time of issuance of the Series A
Preferred Securities, but will not apply to any payment of distributions or
other amounts due to the extent the Series A Issuer does not have sufficient
available funds to pay such distributions or other amounts due (which will occur
in the event that MidAmerican Energy has failed to make a payment of principal
or interest on the Series A Debentures). There are no preconditions to a holder
of Series A Preferred Securities instituting a legal proceeding directly against
MidAmerican Energy to enforce such holder's rights under the Series A Guarantee.
If the Guarantee Trustee fails to enforce the Series A Guarantee, any Holder of
Series A Preferred Securities may institute a legal proceeding directly against
MidAmerican Energy to enforce such Holder's rights under the Series A Guarantee
without first instituting a legal proceeding against the Series A Issuer, the
Guarantee Trustee or any other person or entity. If and to the extent
MidAmerican Energy defaults on its obligation to pay amounts payable on the
Series A Debentures, the Series A Issuer would lack sufficient available funds
for the payment of distributions on or amounts payable on redemption of the
Series A Trust Securities and, in such event, Holders of the Series A Preferred
Securities would not be able to rely on the Series A Guarantee for payment of
such amounts. Instead, Holders of Series A Preferred Securities would have the
limited enforcement rights described under "Description of Preferred Securities;
Events of Default; Notice" in the accompanying Prospectus.
 
                    CERTAIN TERMS OF THE SERIES A GUARANTEE
 
GENERAL
 
    The following summary description of the Series A Guarantee sets forth
certain portions of the description of the terms and provisions of the Series A
Guarantee included in the accompanying Prospectus under the heading,
"Description of the Guarantees," to which reference is hereby made. This summary
of certain terms and provisions of the Series A Guarantee does not purport to be
complete and is subject to, and qualified in its entirety by reference to, the
Series A Guarantee. The form of Series A Guarantee has been filed as an exhibit
to the Registration Statement of which this Prospectus Supplement and the
accompanying Prospectus are a part.
 
    MidAmerican Energy will guarantee, on an unsecured subordinated basis, the
obligations of the Series A Issuer with respect to the Series A Preferred
Securities; provided that the Series A Guarantee will not apply to any payment
of Distributions if and to the extent that the Series A Issuer does not have
funds sufficient to make such payments. If MidAmerican Energy does not make
interest payments on the Series A Debentures held by the Series A Issuer, it is
expected that the Series A Issuer will not pay Distributions on the Series A
Preferred Securities. The Series A Guarantee will rank subordinate and junior in
right of payment to all liabilities of MidAmerican Energy (except liabilities
that may be made PARI
 
                                      S-14
<PAGE>
PASSU with the Series A Guarantee by their terms). See "Description of the
Guarantees -- Status of the Guarantees" in the accompanying Prospectus.
 
EVENTS OF DEFAULT
 
    An event of default under the Series A Guarantee will occur upon the failure
of MidAmerican Energy to perform any of its payment obligations thereunder.
 
    If the Guarantee Trustee fails to enforce the Series A Guarantee, any holder
of Series A Preferred Securities may institute a legal proceeding directly
against MidAmerican Energy to enforce such holder's rights under the Series A
Guarantee without first instituting a legal proceeding against the Series A
Issuer, the Guarantee Trustee or any other person or entity. The Series A
Guarantee is a guarantee of payment, not of collection.
 
TERMINATION OF THE SERIES A GUARANTEE
 
    The Series A Guarantee will terminate and be of no further force and effect
upon full payment of the Redemption Price of all Series A Preferred Securities,
the distribution of Series A Debentures to holders of Series A Preferred
Securities in exchange for all of the Series A Preferred Securities or upon
payment in full of the amounts payable upon liquidation of the Series A Issuer.
 
                    CERTAIN TERMS OF THE SERIES A DEBENTURES
 
GENERAL
 
    The following summary description of the Series A Debentures sets forth
certain portions of the description of the terms and provisions of the
Debentures included in the accompanying Prospectus under the heading,
"Description of the Debentures," to which reference is hereby made. This summary
of certain terms and provisions of the Series A Debentures does not purport to
be complete and is subject to, and qualified in its entirety by reference to,
the Indenture, including the Series A Supplemental Indenture. The forms of
Indenture and Supplemental Indenture (as defined in the accompanying Prospectus)
have been filed as exhibits to the Registration Statement of which this
Prospectus Supplement and the accompanying Prospectus are a part.
 
    Concurrently with the issuance of the Series A Preferred Securities, the
Series A Issuer will invest the proceeds thereof, together with the Series A
Common Securities, in the Series A Debentures issued by MidAmerican Energy to
the Series A Issuer. The Series A Debentures will bear interest at the annual
rate of     %, payable quarterly in arrears, except in the event of an
extension, on March 1, June 1, September 1 and December 1 of each year
commencing            , 19  . Interest which is accrued and unpaid after the
quarterly payment date therefor will bear additional interest on the amount
thereof (to the extent permitted by law, compounded quarterly) at the rate
specified for the Series A Debentures.
 
    The Series A Debentures will be issued under the Indenture and the Series A
Supplemental Indenture. The Series A Debentures will mature on            ,
20  , which date may be extended at any time at the election of MidAmerican
Energy for one or more periods, but in no event to a date later than
             , 20  (such date, as it may be extended, the "Maturity Date"),
provided that at the time such election is made and at the time of extension (i)
MidAmerican Energy is not in bankruptcy, otherwise insolvent or in liquidation,
(ii) MidAmerican Energy is not in default in the payment of any interest or
principal on the Series A Debentures, (iii) the Series A Issuer is not in
arrears on payments of Distributions on the Series A Preferred Securities and no
deferred Distributions are accumulated, (iv) the Series A Debentures are rated
not less than BBB - by Standard & Poor's Ratings Services or Baa3 by Moody's
Investors Service, Inc. or the equivalent by any other nationally recognized
statistical rating organization and (v) the extended Maturity Date is no later
than the 49th anniversary of the initial issuance of the Series A Preferred
Securities; provided, however, that, if MidAmerican Energy exercises
 
                                      S-15
<PAGE>
its right to liquidate the Series A Issuer and distribute the Series A Preferred
Securities, effective upon such exercise the Maturity Date of the Series A
Debentures may be changed to any dates elected by MidAmerican Energy that is (i)
no earlier than the date five years after the initial issuance of the Series A
Preferred Securities and (ii) no later than the date 30 years (plus an extended
term of up to an additional 19 years if the above-referenced conditions are
satisfied) after the date of the initial issuance of the Series A Preferred
Securities. The Series A Debentures will be unsecured and will rank junior and
be subordinate in right of payment to all Senior Indebtedness of MidAmerican
Energy. See "Description of the Debentures -- Subordination" in the accompanying
Prospectus.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
    MidAmerican Energy has the right at any time and from time to time, so long
as no Event of Default under the Indenture has occurred and is continuing, to
extend the interest payment period for the Series A Debentures for up to 20
consecutive quarters; provided that no Extension Period shall extend beyond the
maturity of the Series A Debentures and that MidAmerican Energy may not defer
any payment of Additional Interest Attributable to Taxes (which shall be payable
on the relevant interest payment date). At the end of the Extension Period,
MidAmerican Energy is obligated to pay all interest then accrued and unpaid
(together with interest thereon to the extent permitted by law). During any such
Extension Period MidAmerican Energy may not, and may not permit any of its
subsidiaries to, (i) declare or pay any dividends or distribution on, or redeem,
purchase, acquire, or make a liquidation payment with respect to, any of
MidAmerican Energy's capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of MidAmerican Energy (including other debentures issued pursuant to
the Indenture) that rank PARI PASSU with or junior in interest to the Series A
Debentures or make any guarantee payments with respect to any guarantee by
MidAmerican Energy of the debt securities of any of its subsidiaries if such
guarantee ranks PARI PASSU with or junior in interest to such series of
Debentures (other than (a) dividends or distributions in common stock of
MidAmerican Energy, (b) payments under any Guarantee, and (c) purchases of
common stock related to the issuance of common stock under any of MidAmerican
Energy's benefit plans for its directors, officers or employees). This covenant
effectively requires that any Extension Period with respect to the Series A
Debentures also apply to other debentures which may be issued by MidAmerican
Energy pursuant to the Indenture. Prior to the termination of any Extension
Period, MidAmerican Energy may further extend the interest payment period,
provided that such Extension Period, together with all such previous and further
extensions thereof, may not exceed 20 consecutive quarters or extend beyond the
maturity of the Series A Debentures. Upon the termination of any Extension
Period and the payment of all amounts then due, MidAmerican Energy may select a
new Extension Period subject to the above requirements.
 
REDEMPTION
 
    The Series A Debentures are redeemable prior to maturity at the option of
MidAmerican Energy (i) at any time on or after             , 200    , in whole
or in part, and (ii) if a Special Event occurs and is continuing, in whole, but
not in part, in each case at a Redemption Price equal to 100% of the principal
amount thereof plus accrued interest to the Redemption Date. The Series A
Debentures will be subject to optional redemption in whole, but not in part,
upon the termination and liquidation of the Series A Issuer pursuant to an order
for the dissolution, termination or liquidation of the Series A Issuer entered
by a court of competent jurisdiction. For so long as the Series A Trust is the
holder of all Series A Debentures outstanding, the proceeds of any redemption
described in this paragraph shall be used by the Series A Issuer to redeem the
Series A Preferred Securities and the Series A Common Securities in accordance
with their terms.
 
                                      S-16
<PAGE>
    MidAmerican Energy may not redeem the Series A Debentures in part unless all
accrued and unpaid interest (including any Additional Interest) has been paid in
full on all Series A Debentures outstanding for all quarterly interest periods
on or prior to the Redemption Date.
 
DISTRIBUTIONS OF SERIES A DEBENTURES
 
    Under certain circumstances involving the termination of the Series A
Issuer, Series A Debentures may be distributed to the holders of the Series A
Preferred Securities in liquidation of the Series A Issuer, after satisfaction
of all liabilities to creditors of the Series A Issuer as provided by applicable
law. If distributed to holders of Series A Preferred Securities in liquidation,
the Series A Debentures will initially be issued in the form of one or more
global securities, and DTC, or any successor depositary for the Series A
Preferred Securities, will act as depositary for the Series A Debentures. It is
anticipated that the depositary arrangements for the Series A Debentures, if
distributed, would be substantially identical to those in effect for the Series
A Preferred Securities. Neither MidAmerican Energy, the Debenture Trustee, any
Paying Agent nor any other agent of MidAmerican Energy or the Debenture Trustee
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of persons holding Series A Debentures in the
form of a global security for the Series A Debentures or for maintaining,
supervising or reviewing any records relating to such holders.
 
    A global security will be exchangeable for Series A Debentures registered in
the names of persons other than DTC or its nominee only if (i) DTC notifies
MidAmerican Energy that it is unwilling or unable to continue as a depositary
for such global security and no successor depositary shall have been appointed,
or if at any time DTC ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, at a time when DTC is required to
be so registered to act as such depositary, (ii) MidAmerican Energy in its sole
discretion determines that such global security shall be so exchangeable, or
(iii) there shall have occurred and be continuing an Event of Default with
respect to such global security. Any global security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for definitive
certificates registered in such names as DTC shall direct. It is expected that
such instructions will be based upon directions received by DTC from its
Participants (as defined in the accompanying Prospectus) with respect to the
ownership of beneficial interests in such global security. In the event that
Series A Debentures are issued in definitive form, such Series A Debentures will
be issued in denominations of $25 and integral multiples thereof and may be
transferred or exchanged at the offices described below.
 
    Payments on Series A Debentures represented by a global security will be
made to DTC, as the depositary for the Series A Debentures. In the event Series
A Debentures are issued in definitive form, principal and interest will be
payable, the transfer of the Series A Debentures will be registrable, and Series
A Debentures will be exchangeable for Series A Debentures of other denominations
of a like aggregate principal amount, at the corporate office of the Debenture
Trustee in Chicago, Illinois, or at the offices of any paying or transfer agent
appointed by MidAmerican Energy, provided that payment of interest may be made,
at the option of MidAmerican Energy, by check mailed to the address of the
persons entitled thereto or by wire transfer. In addition, if the Series A
Debentures are issued in certificated form, the record dates for payment of
interest will be the 15th day preceding the first day of March, June, September
and December, respectively. For a description of DTC and the terms of the
depositary arrangements relating to payments, transfers, voting rights and other
matters, see "Description of the Preferred Securities -- Book-Entry Only
Issuance -- The Depository Trust Company" in the accompanying Prospectus.
 
    If the Series A Debentures are distributed to the holders of Series A
Preferred Securities upon the liquidation of the Series A Issuer, MidAmerican
Energy will use its best efforts to list the Series A Debentures on such stock
exchanges, if any, as the Series A Preferred Securities are then listed.

                     UNITED STATES FEDERAL INCOME TAXATION
 
GENERAL
 
    The following is a summary of certain of the material United States federal
income tax consequences of the purchase, ownership and disposition of Series A
Preferred Securities. Unless otherwise stated, this summary deals only with
Series A Preferred Securities held as capital assets by holders that purchase
the Series A Preferred Securities upon original issuance. This summary does not
address all the tax consequences that may be relevant to holders that may be
subject to special tax treatment such as, for example, banks, real estate
investment trusts, regulated investment companies, insurance companies, dealers
in securities or currencies, tax-exempt investors, persons whose functional
currency is other than the United States dollar, persons who hold Series A
Preferred Securities as part of a straddle, hedging or conversion transaction
or, except as specifically described herein, foreign taxpayers. In addition,
this summary does not address any aspects of state, local, or foreign laws. This
summary is based on the Internal Revenue Code of 1986, as amended, Treasury
regulations promulgated thereunder and administrative and judicial
interpretations thereof, as of the date hereof, all of which are subject to
change, possibly on a retroactive basis. Each holder should consult its tax
advisor as to its particular tax consequences of acquiring, holding, and
disposing of the Series A Preferred Securities, including the tax consequences
under state, local, and foreign laws.
 
CLASSIFICATION OF THE SERIES A DEBENTURES
 
    It is a condition to the issuance of the Series A Preferred Securities that
Sidley & Austin, acting as counsel to the underwriters in connection with this
offering, render its opinion generally to the effect that, under then current
United States federal income tax law and assuming full compliance with the terms
of the Indenture (and certain other documents), and based on certain facts and
assumptions contained in such opinion, the Series A Debentures held by the
Series A Trust will be classified for United States federal income tax purposes
as indebtedness of the Company. Accordingly, corporate holders of Series A
Preferred Securities will not be entitled to a dividends-received deduction with
respect to any income recognized with respect to the Series A Preferred
Securities.
 
CLASSIFICATION OF THE SERIES A TRUST
 
    It is a condition to the issuance of the Series A Preferred Securities that
Sidley & Austin, acting as counsel to the underwriters in connection with this
offering, render its opinion generally to the effect that, under then current
United Stated federal income tax law and assuming full compliance with the terms
of the Series A Trust Agreement and the Indenture (and certain other documents),
and based on certain facts and assumptions contained in such opinion, the Series
A Trust will be classified for United States federal income tax purposes as a
grantor trust and not as an association taxable as a corporation. Accordingly,
for United States federal income tax purposes, each holder of Series A Preferred
Securities will generally be considered the owner of an undivided interest in
the Series A Debentures, and each holder will be required to include in its
gross income any original issue discount ("OID") accrued with respect to its
allocable share of those Series A Debentures. Investors should be aware that the
foregoing opinions of Sidley & Austin have not been confirmed by the Internal
Revenue Service (the "Service"), by private ruling or otherwise, and are not
binding on the Service or the courts.
 
    The Company, the Series A Trust, and, by its acceptance of a Series A
Preferred Security or a beneficial interest therein, the holder of, and any
person that acquires a beneficial interest in, such Series A Preferred Security
agree to treat such Series A Preferred Security and the Series A Debentures
consistently with the foregoing opinions.
 
                                      S-18
<PAGE>
ORIGINAL ISSUE DISCOUNT
 
    Because the Company has the option, under the terms of the Series A
Debentures, to defer payments of interest by extending interest payment periods
for up to 20 quarters, all of the stated interest payments on the Series A
Debentures will be treated as OID. Holders of debt instruments issued with OID
must include that discount in income on an economic accrual basis before the
receipt of cash attributable to the discount, regardless of their method of tax
accounting. Generally, all of a holder's taxable interest income with respect to
the Series A Debentures will be accounted for as OID, and actual distributions
of stated interest will not be separately reported as taxable income. The amount
of OID that accrues in any quarter will approximately equal the amount of the
interest that accrues on the Series A Debentures in that quarter at the stated
interest rate. In the event that the interest payment period is extended,
holders will continue to accrue OID approximately equal to the amount of the
interest payment due at the end of the extended interest payment period on an
economic accrual basis over the length of the extended interest period.
 
MARKET DISCOUNT AND PREMIUM
 
    Holders of Series A Preferred Securities other than holders that purchased
the Series A Preferred Securities upon original issuance may be considered to
have acquired their undivided interest in the Series A Debentures with market
discount, amortizable bond premium or acquisition premium as such terms are
defined for the United States federal income tax purposes. Such holders are
advised to consult their tax advisors as to the income tax consequences of the
acquisition, ownership and disposition of the Series A Preferred Securities.
 
RECEIPT OF SERIES A DEBENTURES OR CASH UPON LIQUIDATION OF THE SERIES A TRUST
 
    Under certain circumstances, as described under the caption "Certain Terms
of the Series A Preferred Securities--Termination of Series A Issuer and
Distribution of Series A Debentures" and "Certain Terms of the Series A
Debentures--Distributions of Series A Debentures," Series A Debentures may be
distributed to holders in exchange for the Series A Preferred Securities and in
liquidation of the Series A Trust. Under current United States federal income
tax law, such a distribution would be treated as a non-taxable event to each
holder, and each holder would have an aggregate tax basis in the Series A
Debentures equal to such holder's aggregate tax basis in its Series A Preferred
Securities. A holder's holding period in the Series A Debentures so received in
liquidation of the Series A Trust would include the period during which the
Series A Preferred Securities were held by such holder.
 
    Under certain circumstances described herein (see "Certain Terms of the
Series A Preferred Securities -- Redemption" and "Certain Terms of the Series A
Debentures -- Distributions of Series A Debentures,"), the Series A Debentures
may be redeemed for cash and the proceeds of such redemption distributed to
holders in redemption of their Series A Preferred Securities. Under current
United States federal income tax law, such a redemption would constitute a
taxable disposition of the redeemed Series A Preferred Securities, and a holder
would recognize gain or loss as if it sold such redeemed Series A Preferred
Securities for cash. See "Sales of Series A Preferred Securities" below.
 
SALES OF SERIES A PREFERRED SECURITIES
 
    A holder that sells Series A Preferred Securities will recognize gain or
loss equal to the difference between such holder's adjusted tax basis in the
Series A Preferred Securities and the amount realized on the sale of such Series
A Preferred Securities. A holder's adjusted tax basis in the Series A Preferred
Securities will generally be the initial purchase price increased by OID
previously includible in such holder's gross income to the date of disposition
and decreased by payments received on the Series A Preferred Securities. Such
gain or loss will generally be a capital gain or loss and will generally be a
long-term capital gain or loss if the Series A Preferred Securities have been
held for more than one year.
 
                                      S-19
<PAGE>
    The Series A Preferred Securities may trade at prices that do not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Series A Debentures. A holder that disposes of Series A Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest on the Series A Debentures through the date
of disposition in income as ordinary income, and to add such amount to such
holder's adjusted tax basis in the pro rata share of the underlying Series A
Debentures deemed disposed of. To the extent that the selling price is less than
the holder's adjusted tax basis (so determined), a holder will recognize a
capital loss. Subject to certain limited exceptions, capital losses cannot be
applied to offset ordinary income for United States federal income tax purposes.
 
UNITED STATES ALIEN HOLDERS
 
    For purposes of this discussion, a "United States Alien Holder" is any
corporation, individual, partnership, estate or trust that is, as to the United
States, a foreign corporation, a nonresident alien individual, a foreign
partnership, or a nonresident fiduciary of a foreign estate or trust. The
discussion assumes that income with respect to the Series A Preferred Security
is not effectively connected with a trade or business in the United States in
which the United States Alien Holder is engaged.
 
    Under current United States federal income tax law, and subject to the
discussion of backup withholding in the following section: (1) payments of
principal and interest (including OID) by the Series A Trust or any of its
paying agents to any holder of a Series A Preferred Security that is a United
States Alien Holder will not be subject to withholding of United States federal
income tax; provided that, in the case of interest, (a) the beneficial owner of
the Series A Preferred Security does not actually or constructively own 10% of
more of the total combined voting power of all classes of stock of the Company
entitled to vote, (b) the beneficial owner of the Series A Preferred Security is
not a controlled foreign corporation that is related, directly or indirectly, to
the Company through stock ownership, and (c) either (A) the beneficial owner of
the Series A Preferred Security certifies to the Series A Trust or its agent,
under penalties of perjury, that it is a United States Alien Holder and provides
its name and address or (B) a securities clearing organization, bank or other
financial institution that holds customers' securities in the ordinary course of
its trade or business (a "Financial Institution"), and holds the Series A
Preferred Securities in such capacity, certifies to the Series A Trust or its
agent, under penalties of perjury, that such statement has been received from
the beneficial owner by it or by a Financial Institution between it and the
beneficial owner and furnishes the Series A Trust or its agent with a copy
thereof; and (2) a United States Alien Holder of a Series A Preferred Security
will generally not be subject to withholding of United States federal income tax
on any gain realized upon the sale or other disposition of a Series A Preferred
Security.
 
    On April 15, 1996, proposed Treasury Regulations (the "1996 Proposed
Regulations") were issued which, if adopted in final form, could affect the
United States taxation of United States Alien Holders. The 1996 Proposed
Regulations are generally proposed to be effective for payments after December
31, 1997, regardless of the issue date of the instrument with respect to which
such payments are made, subject to certain transition rules. It cannot be
predicted at this time whether the 1996 Proposed Regulations will become
effective as proposed or what, if any, modifications may be made to them.
Prospective investors are urged to consult their tax advisors with respect to
the effect the 1996 Proposed Regulations may have if adopted.
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
    Under current United States federal income tax law, information reporting
requirements apply to interest (including OID) and principal payments made to,
and to the proceeds of sales before maturity by, certain non-corporate persons.
In addition, a 31% backup withholding tax applies if a non-corporate person (i)
fails to furnish such person's Taxpayer Identification Number ("TIN") (which,
for an individual, is his or her Social Security Number) to the payor in the
manner required, (ii) furnishes an incorrect TIN
 
                                      S-20
<PAGE>
and the payor is so notified by the Service, (iii) is notified by the Service
that such person has failed properly to report payments of interest and
dividends or (iv) in certain circumstances, fails to certify, under penalties of
perjury, that such person has not been notified by the Service that such person
is subject to backup withholding for failure properly to report interest and
dividend payments. Backup withholding does not apply with respect to payments
made to certain exempt recipients, including corporations, tax-exempt
organizations, qualified pension and profit-sharing trusts and individual
retirement accounts, provided that they establish entitlement to an exemption.
 
    In the case of a United States Alien Holder, backup withholding and
information reporting do not apply to payments of principal and interest on a
Series A Preferred Security with respect to which such Holder has provided the
required certification under penalties of perjury that such Holder is a United
States Alien Holder or has otherwise established an exemption, provided that
certain conditions are satisfied.
 
    In general, (i) principal or interest payments on a Series A Preferred
Security collected outside the United States by a foreign office of a custodian,
nominee or other agent acting on behalf of a beneficial owner of a Series A
Preferred Security and (ii) payments on the sale, exchange or retirement of a
Series A Preferred Security to or through a foreign office of a broker are not
subject to backup withholding or information reporting. However, if such
custodian, nominee, agent or broker is a United States person, a controlled
foreign corporation for United States tax purposes, or a foreign person 50% of
more of whose gross income is effectively connected with the conduct of a United
States trade or business for a specified three-year period, such custodian,
nominee, agent or broker may be subject to certain information reporting (but
not backup withholding) requirements with respect to such payments.
 
    Backup withholding tax is not an additional tax. Rather, any amounts
withheld from a payment to a person under the backup withholding rules are
allowed as a refund or a credit against such person's United States federal
income tax, provided that the required information is furnished to the Service.
 
POSSIBLE TAX LAW CHANGES
 
    On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill"), the
revenue portion of President Clinton's budget proposal, was released. The Bill
would, among other things, generally deny interest deductions for interest on an
instrument, issued by a corporation, that has a maximum weighted average
maturity of more than 40 years. The Bill would also generally deny interest
deductions for interest on an instrument, issued by a corporation, that has a
maximum term of more than 20 years and that is not shown as indebtedness on the
separate balance sheet of the issuer, or where the instrument is issued to a
related party (other than a corporation), where the holder or some other related
party issues a related instrument that is not shown as indebtedness on the
issuer's consolidated balance sheet. For purposes of determining the weighted
average maturity or the term of an instrument, any right to extend would be
treated as exercised. The above-described provisions of the Bill were proposed
to be effective generally for instruments issued on or after December 7, 1995.
If either provision were to apply to the Series A Debentures, the Company would
be unable to deduct interest on the Series A Debentures. However, on March 29,
1996, the Chairmen of the Senate Finance and House Ways and Means Committees
issued a joint statement to the effect that it was their intention that the
effective date of the President's legislative proposals, if adopted, will be no
earlier than the date of appropriate Congressional action. The Company believes,
that, under current law, it will be able to deduct interest on the Series A
Debentures. There can be no assurance, however, that current or future
legislative proposals or final legislation will not affect the ability of the
Company to deduct interest on the Series A Debentures. Such a change could give
rise to a Tax Event, which may permit the Company to cause a redemption of the
Series A Preferred Securities. See "Certain Terms of the Series A Preferred
Securities -- Special Event Redemption." Such a tax law change would not alter
the United States federal income tax consequences of the purchase, ownership and
disposition of Series A Preferred Securities to holders thereof.

</TABLE>
 
    Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all the Series A Preferred
Securities offered hereby, if any are taken.
 
    The Underwriters propose to offer the Series A Preferred Securities in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus Supplement and in part to certain securities
dealers at such price less a concession of $     per Series A Preferred
Security. The Underwriters may allow, and such dealers may reallow, a concession
not in excess of $     per Series A Preferred Security to certain brokers and
dealers. After the Series A Preferred Securities are released for sale to the
public, the offering price and other selling terms may from time to time be
varied by the Representatives.
 
    In view of the fact that the proceeds from the sale of the Series A
Preferred Securities will be used to purchase the Series A Debentures issued by
MidAmerican Energy, the Underwriting Agreement provides that MidAmerican Energy
will pay as Underwriters' Compensation for the Underwriters arranging the
investment therein of such proceeds an amount of $     per Series A Preferred
Security for the accounts of the several Underwriters.
 
    MidAmerican Energy and the Series A Issuer have agreed that, during the
period beginning from the date of the Underwriting Agreement and continuing to
and including the earlier of (i) the date on which the distribution of the
Series A Preferred Securities ceases, as determined by the Representatives, and
(ii) 30 days after the issuance of the Series A Preferred Securities, they will
not offer, sell, contract to sell or otherwise dispose of any securities, any
other beneficial interests in the Series A Issuer or any preferred securities or
interests of any other issuer, as the case may be, that are substantially
similar to the Series A Preferred Securities (including any guarantee of such
securities or interests) or any securities that are convertible into or
exchangeable for, or that represent the right to receive, any such securities or
other interests, without the prior written consent of the Representatives,
except for the Series A Preferred Securities, the Series A Common Securities and
the Series A Guarantee.

    Prior to this offering, there has been no public market for the Series A
Preferred Securities. Application will be made to list the Series A Preferred
Securities on the New York Stock Exchange under the symbol "     ". In order to
meet one of the requirements for listing the Series A Preferred Securities on
the New York Stock Exchange, the Underwriters will undertake to sell lots of 100
or more Series A Preferred Securities to a minimum of 400 beneficial holders.
Trading of the Series A Preferred Securities on the New York Stock Exchange is
expected to commence within a thirty-day period after the initial delivery of
the Series A Preferred Securities. The Representatives have advised MidAmerican
Energy that they intend to make a market in the Series A Preferred Securities
prior to the commencement of trading on the New York Stock Exchange, but are not
obligated to do so and may discontinue market-making at any time without notice.
No assurance can be given as to the liquidity of the trading market for the
Series A Preferred Securities.
 
    MidAmerican Energy and the Series A Issuer have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933.
 
    Certain of the Underwriters or their affiliates have provided from time to

                                   ----------
 
    MidAmerican Energy Financing I and MidAmerican Energy Financing II, each a
statutory business trust formed under the laws of the State of Delaware (each,
an "Issuer" and, collectively, the "Issuers") may severally offer, from time to
time, their respective preferred securities (the "Preferred Securities")
representing preferred undivided beneficial interests in the assets of each
Issuer. MidAmerican Energy Company, an Iowa corporation ("MidAmerican Energy"),
will be the sole owner of the undivided common beneficial interests in such
assets represented by common securities (the "Common Securities", together with
the Preferred Securities herein referred to as the "Trust Securities") of each
Issuer. The payment of periodic cash distributions ("Distributions") with
respect to the Preferred Securities and payments on liquidation or redemption
with respect to such Preferred Securities will be each guaranteed by MidAmerican
Energy in the case of each Issuer (a "Guarantee"), in each case only out of
funds held by such Issuer. Concurrently with the issuance by an Issuer of its
Preferred Securities, such Issuer will invest the proceeds thereof in
MidAmerican Energy's junior subordinated debentures (the "Debentures") having
terms corresponding to such Issuer's Preferred Securities. The Debentures will
be unsecured and subordinate indebtedness of MidAmerican Energy issued under an
Indenture dated as of             , 1996 between the Company and The First
National Bank of Chicago, as Trustee (such Indenture, as the same may be
supplemented or amended from time to time, herein referred to as the
"Indenture"). The Debentures held by each Issuer will be its sole asset, and the
interest and payments of principal on such Debentures will be its only revenues.
The Debentures purchased by an Issuer may be subsequently distributed pro rata
to holders of Preferred Securities and Common Securities in connection with the
dissolution of such Issuer. See "Description of Preferred Securities--
Termination of an Issuer and Distribution of Debentures". In addition, upon the
occurrence of certain events, MidAmerican Energy may redeem the Debentures and
cause the redemption of the Preferred Securities. See "Description of the
Preferred Securities--Redemption."
 
    The Preferred Securities may be offered in amounts, at prices and on terms
to be determined at the time of offering, provided, however, that the aggregate
initial public offering price of all Preferred Securities issued pursuant to the
Registration Statement of which this Prospectus forms a part shall not exceed
$500,000,000 (subject to reduction in the event of sales of certain other
securities included in such Registration Statement)). Certain specific terms of
each Issuer's Preferred Securities in respect of which this Prospectus is being
delivered will be set forth in an accompanying Prospectus Supplement, including,
where applicable and to the extent not set forth herein, the identity of the
Issuer, the specific title, the aggregate amount, the distribution rate (or the
method for determining such rate), the stated liquidation preference, redemption
provisions, other rights, the initial public offering price and any other
special terms, as well as any planned listing on a securities exchange, of such
Preferred Securities.
 
    The Preferred Securities may be sold in a public offering to or through
underwriters or dealers designated from time to time. See "Plan of
Distribution." The names of any of the underwriters or dealers involved in the
sale of the Preferred Securities in respect of which this Prospectus is being
delivered, the number of Preferred Securities to be purchased by any such
underwriters or dealers, any applicable commissions or discounts and the net
proceeds to each Issuer will be set forth in the applicable Prospectus
Supplement.
 
    Each Prospectus Supplement will also contain information concerning certain
United States federal income tax considerations applicable to the Preferred
Securities offered thereby.

                             AVAILABLE INFORMATION
 
    The Company is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Securities and Exchange Commission (the "Commission"). MidAmerican Energy and
the Issuers have filed with the Commission a registration statement on Form S-3
(the "Registration Statement") under the Securities Act of 1933, as amended (the
"Securities Act") with respect to the Preferred Securities offered hereby and
certain other securities. This Prospectus does not contain all of the
information set forth in the Registration Statement and reference is hereby made
to the Registration Statement and the exhibits thereto for further information
with respect to the Company and the Preferred Securities offered hereby. Such
reports, proxy statements, Registration Statement and exhibits and other
information can be inspected and copied at the public reference facilities
maintained by the Commission at 450 Fifth Street, N.W., Room 1024, Washington,
D.C. 20549, and at its Northeast Regional Office located at 7 World Trade
Center, Suite 1300, New York, New York 10048 and Midwest Regional Office located

60661-2511. Copies of such material can be obtained at prescribed rates from the
Public Reference Section of the Commission, 450 Fifth Street, N.W., Washington,
D.C. 20549. The Company is subject to the electronic filing requirements of the
Commission. Accordingly, pursuant to the rules and regulations of the
Commission, certain documents, including annual and quarterly reports and proxy
statements, filed by the Company with the Commission have been filed
electronically. The Commission also maintains a World Wide Web site that
contains reports, proxy and information statements and other information
regarding registrants (including the Company) that file electronically with the
Commission at (http:// www.sec.gov). Certain of the Company's securities are
listed on the New York Stock Exchange and such reports, proxy statements and
other information may also be inspected at the offices of the New York Stock
Exchange, Inc., 20 Broad Street, New York, New York 10005.
 
    No separate financial statements of the Issuers are included herein. The
Company considers that such financial statements would not be material to
holders of the Preferred Securities because: (i) all of the Common Securities of
the Issuers are owned by MidAmerican Energy, a reporting company under the
Exchange Act; (ii) the Issuers have no independent operations, but exist for the
sole purpose of issuing the Trust Securities and holding the Debentures as trust
assets; and (iii) the obligations of the Issuers under the Preferred Securities,
to the extent funds are available therefor, are fully and unconditionally
guaranteed to the extent set forth herein by MidAmerican Energy.

                                  THE ISSUERS
 
GENERAL
 
    Each of the Issuers is a statutory business trust formed under Delaware law
pursuant to (i) a trust agreement executed by MidAmerican Energy as the
depositor of each Issuer (the "Depositor"), and the Issuer Trustees (as defined
herein) and (ii) the filing of a certificate of trust with the Delaware
Secretary of State on October 29, 1996. Each such trust agreement will be
amended and restated in its entirety (as so amended and restated, a "Trust
Agreement" and, collectively, the "Trust Agreements") substantially in the form
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. Each Trust Agreement will be qualified as an indenture under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act").
 
    The Issuers exist for the exclusive purpose of (i) issuing Trust Securities
representing undivided beneficial interests in the Issuers, (ii) holding the
Debentures as Trust Assets and (iii) engaging only in those other activities
necessary or incidental thereto. All of the Common Securities will be owned by
MidAmerican Energy. The Common Securities will rank PARI PASSU, and payments
will be made thereon pro rata, with the Preferred Securities, except that upon
the occurrence and continuance of an Event of Default under the Indenture (see
"Description of the Debentures -- Events of Default"), the rights of the holders
of the corresponding Common Securities to payment in respect of distributions
and payments upon liquidation, redemption or other acquisition of Common
Securities will be subordinated to the rights of the holders of Preferred
Securities. MidAmerican Energy will acquire Common Securities of each Issuer in
an aggregate equal to 3% of the total capital of each Issuer. Each Issuer will
have a term of approximately 30 to 49 years, as specified in the applicable
Prospectus Supplement, but may terminate earlier as provided in the Trust
Agreement with respect to such Issuer. Each Issuer's business and affairs are
conducted by its trustees, each appointed by MidAmerican Energy as holder of the
Common Securities: First Chicago Delaware Inc. (the "Delaware Trustee"), The
First National Bank of Chicago (the "Property Trustee") and three individual
trustees (the "Administrative Trustees") who are employees or officers of or
affiliated with MidAmerican Energy (collectively, the "Issuer Trustees").
 
                           MIDAMERICAN ENERGY COMPANY
 
GENERAL
 
    MidAmerican Energy was formed on July 1, 1995 through the merger (the
"Merger") of Iowa-Illinois Gas and Electric Company ("Iowa-Illinois"), Midwest
Resources Inc. ("Midwest Resources") and Midwest Power Systems Inc. ("Midwest
Power") with and into MidAmerican Energy. MidAmerican Energy is a combination
electric and natural gas public utility engaged in the generation, transmission,
distribution and sale of electric energy in Illinois, Iowa and South Dakota, and
the purchase, distribution, transportation and sale of natural gas in those
states and in the state of Nebraska. MidAmerican Energy's nonregulated
operations are conducted by its MidAmerican Capital Company ("MidAmerican
Capital") subsidiary; a separate wholly-owned subsidiary, Midwest Capital Group,
Inc., functions as a regional business development company in the utility
service territory.

<PAGE>
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
    The Preferred Securities and the Common Securities of each Issuer (together,
the "Issuer Securities") will be created pursuant to the terms of the Trust
Agreements. Each Issuer's Preferred Securities will represent undivided
beneficial interests in the assets of such Issuer and entitle registered owners
(the "Holders") thereof to a preference over such Issuer's Common Securities in
certain circumstances with respect to Distributions and amounts payable on
redemption or liquidation, as well as other benefits as described in the
applicable Trust Agreement. The following summaries of certain provisions of the
Trust Agreements do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, the provisions of the Trust
Agreements, including the definitions therein of certain terms, and the Trust
Indenture Act. Wherever particular sections or defined terms of the Trust
Agreements are referred to, such sections or defined terms are incorporated
herein by reference. The Trust Agreements have been filed as exhibits to the
Registration Statement of which this Prospectus forms a part.
 
GENERAL
 
    All of the Common Securities are owned by MidAmerican Energy. The Common
Securities of each Issuer will rank PARI PASSU, and payments will be made
thereon pro rata, with the Preferred Securities of each Issuer based on the
liquidation preference amount of the Trust Securities, except as described
herein under "-- Subordination of Common Securities." (Section 4.03). The
Debentures will be owned by the Issuers and held by the Property Trustee in
trust for the benefit of the Holders of the Trust Securities. (Section 2.09).
The Debentures and the Guarantees, together with the obligations of MidAmerican
Energy with respect to the Preferred Securities under the Indenture, the Trust
Agreements and the Expense Agreements constitute full and unconditional
guarantees of the Preferred Securities by MidAmerican Energy.
 
DISTRIBUTIONS
 
    The Distributions payable on the Preferred Securities will be fixed at the
rate per annum set forth in the applicable Prospectus Supplement. Distributions
that are in arrears will bear interest on the amount thereof at same per annum
rate (to the extent permitted by applicable law, compounded quarterly). The term
"Distributions" as used herein includes interest payable on overdue
Distributions, unless otherwise stated. The amount of Distributions payable for
any period will be computed on the basis of a 360-day year of twelve 30-day
months and for any period shorter than a full month, on the basis of the actual
number of days elapsed. (Section 4.01(b)).
 
    Distributions on the Preferred Securities will be cumulative, will accrue
from the date of initial issuance thereof, and will be payable quarterly in
arrears, on March 1, June 1, September 1 and December 1 of each year, except as
otherwise described below. Such Distributions will originally accrue from, and
include, the date of initial issuance and will accrue to, and include, the first
distribution payment date, and thereafter will accrue from, and exclude, the
last distribution payment date through which Distributions have been paid. In
the event that any date on which Distributions are otherwise payable on the
Preferred Securities is not a Business Day, payment of the distribution payable
on such date will be made on the next succeeding Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, payment of such
distribution shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such date (each date on which
Distributions are otherwise payable in accordance with the foregoing, a
distribution payment date). (Section 4.01(a)). A Business Day is used herein to
mean any day other than a Saturday or a Sunday or a day on which banking
institutions in The City of New York are authorized or required by law or
executive order to remain closed or a day on which the Corporate Trust Office of
the Property Trustee or the Debenture Trustee (as defined herein) is closed for
business.
 
                                       5
<PAGE>
    MidAmerican Energy shall have the right under the Indenture, as supplemented
by a Supplemental Indenture relating to a series of Debentures (a "Supplemental
Indenture"), to extend the interest payment period at any time or from time to
time on each series of Debentures to a period ("Extension Period") not exceeding
20 consecutive quarters. In the event that MidAmerican Energy exercises this
right, during such Extension Period quarterly Distributions on the corresponding
Preferred Securities will be deferred (and the amount of Distributions to which
holders of such Preferred Securities are entitled will accumulate additional
Distributions thereon at the rate per annum set forth in the applicable
Prospectus Supplement, compounded quarterly from the relevant payment date for
such Distributions); provided, however, that distributions attributable to
payments of Additional Interest Attributable to Taxes (as hereinafter defined),
if any, on such Debentures will not be deferred and will be payable on the
relevant interest payment date. During any such Extension Period MidAmerican
Energy may not, and may not permit any of its subsidiaries to, (i) declare or
pay any dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of MidAmerican Energy's capital stock
or (ii) make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of MidAmerican Energy (including other
Debentures) that rank PARI PASSU with or junior in interest to the series of
Debentures to which such Extension Period applies, or make any guarantee
payments with respect to any guarantee by MidAmerican Energy of the debt
securities of any of its subsidiaries if such guarantee ranks PARI PASSU or
junior in interest to such series of Debentures (other than (a) dividends or
distributions in common stock of MidAmerican Energy, (b) payments under any
Guarantee, and (c) purchases of common stock related to the issuance of common
stock under any of MidAmerican Energy's benefit plans for its directors,
officers or employees). This covenant effectively requires that any extension
period with respect to any series of Debentures also apply to all other series
of Debentures. Prior to the termination of any such Extension Period,
MidAmerican Energy may further extend the interest payment period, provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarters and that such Extension Period
may not extend beyond the maturity or the redemption date of the series of the
Debentures in question. Upon the termination of any Extension Period and the
payment of all amounts then due, MidAmerican Energy may select a new extended
interest payment period, subject to the foregoing requirements. See "Description
of the Debentures -- Interest" and "-- Option to Extend Interest Payment
Period."
 
    It is anticipated that the income of each Issuer available for distribution
to the Holders of the Preferred Securities of such Issuer will be limited to
payments on the Debentures to be purchased by such Issuer with the proceeds of
the sale of the Preferred Securities. See "Description of the Debentures." If
MidAmerican Energy does not make interest payments on the Debentures, the
Property Trustee will not have funds available to pay Distributions on the
Preferred Securities and the Common Securities. The payment of Distributions (if
and to the extent an Issuer has sufficient funds available for the payment of
such Distributions) is guaranteed by MidAmerican Energy as set forth herein
under "Description of the Guarantees."
 
    Distributions on the Preferred Securities will be payable to the Holders
thereof as they appear on the register of the applicable Issuer on the relevant
record dates, which as long as the Preferred Securities remain in book-entry
form, will be one Business Day prior to the relevant Distribution Date. Subject
to any applicable laws and regulations and the provision of the applicable Trust
Agreement, each such payment will be made as described under "-- Book-Entry Only
Issuance -- The Depository Trust Company." In the event any Preferred Securities
are not in book-entry form, the relevant record date for such Preferred
Securities shall be the date 15 days prior to the relevant distribution date or
if such date is not a Business Day, the next succeeding Business Day. (Section
4.01(d)).
 
REDEMPTION
 
    MANDATORY REDEMPTION.  Upon the repayment of any series of the Debentures,
whether at maturity or upon earlier redemption as provided in the Indenture, the
proceeds from such repayment shall be
 
                                       6
<PAGE>
applied by the Property Trustee to redeem a Like Amount (as defined herein) of
corresponding Trust Securities, upon not less than 30 nor more than 60 days'
notice, at a redemption price equal to the aggregate Liquidation Amount (as
defined herein) plus accumulated and unpaid Distributions thereon to the
Redemption Date. See "Description of the Debentures -- Optional Redemption."
 
    "Like Amount" means (i) with respect to a redemption of any series of
Preferred Securities, Preferred Securities of such series having a Liquidation
Amount (as defined below) equal to that portion of the principle amount of
Debentures to be contemporaneously redeemed in accordance with the Indenture and
the proceeds of which will be used to pay the Redemption Price of such Preferred
Securities plus accumulated and unpaid Distributions to the date of such
payment, and (ii) with respect to a distribution of Debentures to Holders of any
series of Preferred Securities in connection with a termination or liquidation
of the related Issuer, Debentures having a principal amount equal to the
Liquidation Amount of the Preferred Securities of the Holder to whom such
Debentures are distributed. "Liquidation Amount" means the stated amount of $25
per Preferred Security and Common Security.
 
    OPTIONAL REDEMPTION.  MidAmerican Energy will have the right to redeem the
Debentures of any particular series in whole or in part, on or after a date to
be specified in the Prospectus Supplement with respect to such series of
Debentures and therefore cause a mandatory redemption of the corresponding
Preferred Securities as described above.
 
    SPECIAL EVENT REDEMPTION.  If a Tax Event or an Investment Company Event
(each defined below, a "Special Event") shall occur and be continuing at any
time with respect to an Issuer or the Preferred Securities of such Issuer,
MidAmerican Energy has the right to redeem the corresponding Debentures in
whole, but not in part, and therefore cause a mandatory redemption of such
Preferred Securities at a redemption price equal to the aggregate Liquidation
Amount of such Preferred Securities plus accumulated and unpaid distributions
thereon within 90 days following the occurrence of such Special Event.
 
    "Tax Event" means the receipt by the Issuer of an opinion of counsel (which
may be counsel to the Company or an affiliate but not an employee thereof and
which must be acceptable to the Property Trustee) experienced in such matters to
the effect that, as a result of (a) any amendment to, or change (including any
announced prospective change) in, the laws (or any regulations thereunder) of
the United States or any political subdivision or taxing authority thereof or
therein affecting taxation, or (b) any amendment to, or change in an
interpretation or application of, such laws or regulations by any legislative
body, court, governmental agency or regulatory authority (including the
enactment of any legislation and the publication of any judicial decision or
regulatory determination on or after the date of issuance of the Preferred
Securities), there is more than an insubstantial risk that (i) the Issuer is, or
will be within 90 days of the date of such opinion, subject to United States
federal income tax with respect to interest income received or accrued on the
Debentures, (ii) interest payable by the Company on the Debentures is not, or
within 90 days of the date of such opinion, will not be, deductible by the
Company, in whole or in part, for United States federal income tax purposes, or
(iii) the Issuer is, or will be within 90 days of the date of such opinion,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges.
 
    "Investment Company Event" means the occurrence of a change in law or
regulation or a change in interpretation or application of law or regulation by
any legislative body, court, governmental agency or regulatory authority
("Change in 1940 Act Law") to the effect that an Issuer is or will be considered
an "investment company" that is required to be registered under the Investment
Company Act of 1940, as amended, which Change in 1940 Act Law becomes effective
on or after the date of original issuance of a particular series of Preferred
Securities.
 
REDEMPTION PROCEDURES
 
    MidAmerican Energy may not redeem fewer than all of a particular series of
Debentures then outstanding and an Issuer may not redeem fewer than all of the
corresponding series of the outstanding
 
                                       7
<PAGE>
Preferred Securities then outstanding (i) unless all accrued and unpaid
Distributions have been paid on all such Preferred Securities for all quarterly
distribution periods terminating on or prior to the date of redemption or (ii)
if a partial redemption of such Preferred Securities would result in the
delisting of such Preferred Securities by any national securities exchange on
which such Preferred Securities are then listed.
 
    Preferred Securities redeemed on each date selected for redemption (the
"Redemption Date") shall be redeemed at the Redemption Price with the proceeds
from the contemporaneous redemption of the corresponding Debentures. Redemptions
of the Preferred Securities shall be made and the Redemption Price shall be
deemed payable on each Redemption Date only to the extent that an Issuer has
funds available for the payment of such Redemption Price. (Section 4.02(c)). See
also "Subordination of Common Securities."
 
    If an Issuer gives a notice of redemption in respect of a particular series
of Preferred Securities (which notice will be irrevocable), then, on or before
the Redemption Date, such Issuer, to the extent funds are available, will, so
long as such securities are in book-entry form, irrevocably deposit with DTC
funds sufficient to pay the applicable Redemption Price and will give DTC
irrevocable instructions and authority to pay the Redemption Price to the
beneficial holders of such Preferred Securities. If such Preferred Securities
are no longer in book-entry form, such Issuer, to the extent funds are
available, will irrevocably deposit with the paying agent for such Preferred
Securities funds sufficient to pay the applicable Redemption Price and will give
such paying agent irrevocable instructions and authority to pay the Redemption
Price to the Holders thereof upon surrender of their certificates evidencing
such Preferred Securities. Notwithstanding the foregoing, Distributions payable
on or prior to the Redemption Date for any Preferred Securities called for
redemption shall be payable to the Holders of such Preferred Securities on the
relevant record dates for the related distribution payment dates. If notice of
redemption shall have been given and funds deposited as required, then on the
Redemption Date, all rights of Holders of such Preferred Securities so called
for redemption will cease, except the right of the Holders of such Preferred
Securities to receive the Redemption Price, but without interest thereon, and
such Preferred Securities will cease to be outstanding. In the event that any
date fixed for redemption of Preferred Securities is not a Business Day, then
payment of the amount payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay). In the event that payment of the Redemption Price in
respect of Preferred Securities called for redemption is improperly withheld or
refused and not paid either by the applicable Issuer or by MidAmerican Energy
pursuant to the corresponding Guarantee described herein under "Description of
the Guarantees", Distributions on such Preferred Securities will continue to
accrue at the then applicable rate, from the original Redemption Date to the
date of payment, in which case the actual payment date will be considered the
date fixed for redemption for purposes of calculating the Redemption Price.
 
    Subject to applicable law (including, without limitation, United States
federal securities law), MidAmerican Energy or its subsidiaries may at any time
and from time to time purchase outstanding Preferred Securities by tender, in
the open market or by private agreement.
 
    If less than all the outstanding Trust Securities of an Issuer are to be
redeemed on a Redemption Date, then the aggregate liquidation preference of such
securities to be redeemed shall be allocated on a pro rata basis to the Common
Securities and the Preferred Securities. The particular Preferred Securities to
be redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Property Trustee from the outstanding Preferred Securities of such series
not previously called for redemption, by such method as the Property Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of Preferred Securities in liquidation preference amounts equal to
$25 or integral multiples thereof. The Property Trustee shall promptly notify
the security registrar in writing of the Preferred Securities selected for
redemption and, in the case of any Preferred Securities selected for partial
redemption, the liquidation preference amount thereof to be redeemed. For all
 
                                       8
<PAGE>
purposes of each Trust Agreement, unless the context otherwise requires, all
provisions relating to the redemption of a series of Preferred Securities shall
relate, in the case of any Preferred Securities of such series redeemed or to be
redeemed only in part, to the portion of the liquidation preference amount of
Preferred Securities of such series that has been or is to be redeemed. (Section
4.02(f)).
 
SUBORDINATION OF COMMON SECURITIES
 
    Payment of Distributions on, and the Redemption Price of, Issuer Securities,
shall be made pro rata based on the Liquidation Amount of the Common Securities
and Preferred Securities comprising such Issuer Securities; provided, however,
that if on any distribution payment date or Redemption Date an Event of Default
under the Indenture (as described below, see "Description of the Debentures --
Events of Default") shall have occurred and be continuing, no payment of any
Distribution on, or Redemption Price of, any Common Security corresponding
thereto, and no other payment on account of the redemption, liquidation or other
acquisition of the corresponding Common Securities, shall be made unless payment
in full in cash of all accrued and unpaid Distributions on all outstanding
Preferred Securities of such series for all distribution periods terminating on
or prior thereto, or in the case of payment of the Redemption Price, the full
amount of such Redemption Price on all such outstanding Preferred Securities,
shall have been made or provided for, and all funds available to the Property
Trustee shall first be applied to the payment in full, in cash, of all
Distributions on, or Redemption Price of, Preferred Securities then due and
payable. (Section 4.03(a)).
 
    In the case of any default under a Trust Agreement resulting from an Event
of Default under the Indenture, MidAmerican Energy as Holder of the Common
Securities issued under such Trust Agreement will be deemed to have waived any
such default under such Trust Agreement until the effect of all such defaults
with respect to the Preferred Securities issued under such Trust have been
cured, waived or otherwise eliminated. Until any such default under such Trust
Agreement with respect to such Preferred Securities has been so cured, waived or
otherwise eliminated, the Property Trustee shall act solely on behalf of the
Holders of such Preferred Securities and not the Holders of such Common
Securities, and only Holders of such Preferred Securities will have the right to
direct the Property Trustee to act on their behalf. (Section 4.03(b)).
 
TERMINATION OF AN ISSUER AND DISTRIBUTION OF DEBENTURES
 
    MidAmerican Energy has the right to, at any time, direct the Property
Trustee to dissolve an Issuer and, in connection therewith, after satisfaction
of creditors of such Issuer, if any, cause the Debentures held by such Issuer to
be distributed to the Holders of the Trust Securities of such Issuer on a pro
rata basis in liquidation of such Holders' interests in the Trust. (See "--
Liquidation, Distribution Upon Termination".
 
    There can be no assurance as to the market price for the Debentures which
may be distributed in exchange for Preferred Securities if a termination and
liquidation of an Issuer were to occur. Accordingly, the Debentures which an
investor may subsequently receive on termination and liquidation of an Issuer
may trade at a discount to the price of the Preferred Securities exchanged.
 
LIQUIDATION, DISTRIBUTION UPON TERMINATION
 
    Pursuant to either Trust Agreement, an Issuer shall dissolve and shall be
liquidated by the Property Trustee on the first to occur of: (i) the expiration
of the term of the relevant Trust; (ii) the bankruptcy, dissolution or
liquidation of MidAmerican Energy; (iii) the redemption of all of the Preferred
Securities of such Issuer; (iv) delivery of written direction to the Property
Trustee by MidAmerican Energy, as Depositer, to dissolve such Issuer and
distribute the Debentures held by such Issuer to Holders of its Issuer
Securities and (v) an order for judicial dissolution of such Issuer having been
entered by a court of competent jurisdiction. (Sections 9.01 and 9.02).
 
                                       9
<PAGE>
    If an automatic or early termination occurs as described in clause (i),
(ii), (iv) or (v) above, such Issuer shall be liquidated by the Property Trustee
as expeditiously as the Property Trustee determines to be appropriate by
adequately providing for the satisfaction of liabilities of creditors, if any,
and by distributing to each Holder of Preferred Securities and Common Securities
of such Issuer a Like Amount of Debentures, unless such distribution is
determined by the Property Trustee not to be practical, in which event such
Holders will be entitled to receive, out of the assets of such Issuer available
for distribution to Holders after satisfaction of liabilities of creditors as
provided by applicable law, an amount determined as follows. In the case of
Holders of Preferred Securities, the amount will be equal to the aggregate
liquidation preference of the Preferred Securities plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"), to the extent that there are sufficient assets available. If
such Liquidation Distribution can be paid only in part because such Issuer has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by such Issuer on the Preferred
Securities shall be paid on a pro rata basis. MidAmerican Energy, as Holder of
the Common Securities, will be entitled to receive Distributions upon any such
liquidation pro rata with the Holders of the Preferred Securities, except that
if an Event of Default under the Indenture has occurred and is continuing under
the Indenture, the Preferred Securities shall have a preference over the Common
Securities. (Sections 9.04(a) and 9.04(d)). A Supplemental Indenture may provide
that if an early termination occurs as described in clause (v) above, the
Debentures will be subject to optional redemption in whole but not in part.
 
    On the date fixed for any distribution of Debentures upon termination of an
Issuer (i) the Preferred Securities and the Common Securities issued by such
Issuer will no longer be deemed to be outstanding, (ii) DTC or its nominee, as
the record holder of such Preferred Securities, will receive a registered global
certificate or certificates representing the Debentures to be delivered upon
such distribution and (iii) certificates representing such Preferred Securities
will be deemed to represent Debentures of the corresponding series having an
aggregate principal amount equal to the stated liquidation preference amount of,
and bearing accrued and unpaid interest equal to accrued and unpaid
Distributions on, such Preferred Securities until such certificates are
presented to MidAmerican Energy or its agent for transfer or reissuance.
(Section 9.02(c)).
 
EVENTS OF DEFAULT; NOTICE
 
    Any one of the following events constitutes an Event of Default under the
affected Trust Agreement (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):
 
     (i) the occurrence of an Event of Default as defined in Section 801 of the
Indenture (see "Description of the Debentures -- Events of Default"); or
 
    (ii) default by an Issuer in the payment of any Distribution when it becomes
due and payable, and continuation of such default for a period of 30 days; or
 
    (iii) default by an Issuer in the payment of any Redemption Price of any
Trust Security when it becomes due and payable; or
 
    (iv) default in the performance, or breach, in any material respect, of any
covenant or warranty of the Issuer Trustees in the applicable Trust Agreement
(other than a covenant or warranty a default in the performance of which or the
breach of which is specifically dealt with in clause (ii) or (iii) above), and
continuation of such default or breach for a period of 60 days after there has
been given, by registered or certified mail, to the Property Trustee by the
Holders of Preferred Securities of such Issuer having at least 10% of the total
liquidation preference amount of the outstanding Preferred Securities of such
Issuer, a written notice specifying such default or breach and requiring it to
be remedied and stating that such notice is a Notice of Default thereunder; or
 
                                       10
<PAGE>
    (v) the occurrence of certain events of bankruptcy or insolvency with
respect to an Issuer.
 
    Within five Business Days after the occurrence of any Event of Default, the
Property Trustee shall transmit to the Holders of Trust Securities and
MidAmerican Energy notice of any such Event of Default actually known to the
Property Trustee, unless such Event of Default shall have been cured or waived.
 
MERGER OR CONSOLIDATION OF THE PROPERTY TRUSTEE OR THE DELAWARE TRUSTEE
 
    Any entity into which the Property Trustee or the Delaware Trustee may be
merged or with which it may be consolidated, or any entity resulting from any
merger, conversion or consolidation to which the Property Trustee or the
Delaware Trustee shall be a party, or any entity succeeding to all or
substantially all the corporate trust business of the Property Trustee or the
Delaware Trustee, shall be the successor to such Trustee under the Trust
Agreements, provided such entity shall be otherwise qualified and eligible.
(Section 8.12).
 
BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
    The Depository Trust Company (the "DTC") will act as securities depositary
for all of the Preferred Securities. The Preferred Securities will be issued
only as fully-registered securities registered in the name of Cede & Co. ("DTC's
nominee"). One or more fully-registered global Preferred Securities
certificates, representing the aggregate number of Preferred Securities, will be
issued and will be deposited with DTC.
 
    DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and a "clearing agency"
registered pursuant to the provisions of Section 17A of the 1934 Act. DTC holds
securities that its participants ("Participants") deposit with DTC. DTC also
facilitates the settlement among Participants of securities transactions, such
as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations ("Direct Participants"). DTC is
owned by a number of its Direct Participants and by the New York Stock Exchange,
the American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc. Access to the DTC system is also available to others, such as
securities brokers and dealers, banks and trust companies that clear
transactions through or maintain a direct or indirect custodial relationship
with a Direct Participant ("Indirect Participants"). The rules applicable to DTC
and its Direct Participants and Indirect Participants are on file with the
Commission.
 
    Purchases of Preferred Securities within the DTC system must be made by or
through Direct Participants, which will receive a credit for the Preferred
Securities on DTC's records. The ownership interest of each actual purchaser of
each Preferred Security (the "Beneficial Owner") is in turn to be recorded in
the Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchases, but Beneficial Owners are expected to
receive written confirmations providing details of the transactions, as will as
periodic statements of their holdings, from the Participants through which the
Beneficial Owners purchased Preferred Securities. Transfers of ownership
interests in the Preferred Securities are to be accomplished by entries made on
the books of Participants acting on behalf of Beneficial Owners. Beneficial
Owners will not receive certificates representing their ownership interests in
the Preferred Securities, except in the event that use of the book-entry system
for the Preferred Securities is discontinued.
 
    To facilitate subsequent transfers, all the Preferred Securities deposited
by Direct Participants with DTC are registered in the name of DTC's nominee,
Cede & Co. The deposit of Preferred Securities with DTC and their registration
in the name of Cede & Co. effect no change in beneficial ownership. DTC has
 
                                       11
<PAGE>
no knowledge of the actual Beneficial Owners of the Preferred Securities; DTC's
records reflect only the identity of the Direct Participants to whose accounts
such Preferred Securities are credited, which may or may not be the Beneficial
Owners. The Participants will remain responsible for keeping account of their
holdings on behalf of their customers.
 
    Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants and by
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements that may be in effect from
time to time.
 
    Redemption notices shall be sent to Cede & Co. as the registered Holder of
Preferred Securities. If less than all of the Preferred Securities are being
redeemed, DTC's current practice is to determine by lot the amount of the
interest of each Direct Participant in such issue to be redeemed.
 
    Although voting with respect to the Preferred Securities is limited, in
those cases where a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Issuer as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co. consenting or voting
rights to those Direct Participants to whose accounts the Preferred Securities
are credited on the record date identified in a listing attached to the Omnibus
Proxy. MidAmerican Energy and the Issuers believe that the arrangements among
DTC, Direct and Indirect Participants, and Beneficial Owners will enable the
Beneficial Owners to exercise rights equivalent in substance to the rights that
can be directly exercised by a holder of a beneficial interest in the Issuers.
 
    Distribution payments on the Preferred Securities will be made to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payments on such payment date.
Payments by Participants to Beneficial Owners will be governed by standing
instructions and customary practices, as is the case with securities held for
the account of customers in bearer form or registered in "street name," and such
payments will be the responsibility of such Participant and not of DTC, the
Property Trustee, the applicable Issuer or MidAmerican Energy, subject to any
statutory or regulatory requirements to the contrary that may be in effect from
time to time. Payment of Distributions to DTC is the responsibility of the
Issuer in question, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursement of such payments to the Beneficial
Owners is the responsibility of Participants.
 
    Except as provided herein, a Beneficial Owner will not be entitled to
receive physical delivery of Preferred Securities. Accordingly, each Beneficial
Owner must rely on the procedures of DTC to exercise any rights under the
Preferred Securities.
 
    DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
the Issuer in question and MidAmerican Energy. Under such circumstances, in the
event that a successor securities depositary is not obtained, Preferred
Securities certificates are required to be printed and delivered. Additionally,
the Administrative Trustees (with the consent of MidAmerican Energy) may decide
to discontinue use of the system of book-entry transfers through DTC (or any
successor depositary) with respect to the Preferred Securities. In that event,
certificates for the Preferred Securities will be printed and delivered.
 
    The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that MidAmerican Energy and the Issuers believe
to be reliable, but neither MidAmerican Energy nor the Issuers take
responsibility for the accuracy thereof. Neither MidAmerican Energy nor any
Issuer has responsibility for the performance by DTC or its Participants of
their respective obligations as described herein or under the rules and
procedures governing their respective operations.
 
                                       12

VOTING RIGHTS
 
    Holders of Trust Securities shall be entitled to one vote for each $25 in
liquidation preferences represented by their Trust Securities in respect of any
matter as to which such Holders of Trust Securities are entitled to vote. Except
as described below and under "-- Amendments," and under "Description of the
Guarantees -- Amendments and Assignment" and as otherwise required by law and
the applicable Trust Agreement, the Holders of the Preferred Securities will
have no voting rights. (Section 6.01(a)).
 
    So long as any Debentures of a particular series are held by the Property
Trustee of an Issuer, the Property Trustee shall not (i) direct the time, method
and place of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on the Debenture Trustee with
respect to such Debentures, (ii) waive any past default which is waivable under
Section 813 of the Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all such Debentures shall be due and payable
or (iv) consent to any amendment, modification or termination of the Indenture
or such Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of Preferred Securities having at
least 66 2/3% of the liquidation preference amount of the outstanding Preferred
Securities of such Issuer; provided, however, that where a consent under the
Indenture would require the consent of each Holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior consent of each Holder of Preferred Securities of such Issuer. The
Property Trustee shall not revoke any action previously authorized or approved
by a vote of the holders of Preferred Securities of a particular Issuer except
pursuant to a subsequent vote of the outstanding Preferred Securities of such
Issuer. The Property Trustee shall notify all Holders of an affected series of
Preferred Securities of any notice of default received from the Debenture
Trustee. In addition to obtaining the foregoing approvals of the Holders of the
Preferred Securities of a particular series, prior to taking any of the
foregoing actions, the Property Trustee shall receive an opinion of counsel
experienced in such matters to the effect that the applicable Issuer will be
classified as a "grantor trust" and will not be classified as an association
taxable as a corporation for United States federal income tax purposes on
account of such action. (Section 6.01(b)).
 
    Notwithstanding the foregoing, a Holder of Preferred Securities of a
particular series may institute a proceeding for enforcement of payment to such
Holder directly of principal of or interest on Debentures of the corresponding
series having a principal amount equal to the aggregate liquidation preference
amount of such Preferred Securities of such Holder on or after the due dates
specified in the Debentures.
 
    Any required approval of Holders of Preferred Securities of a particular
series may be given at a separate meeting of Holders of such Preferred
Securities convened for such purpose or pursuant to written consent. The
Administrative Trustees will cause a notice of any meeting at which Holders of
such Preferred Securities are entitled to vote, or of any matter upon which
action by written consent of such Holders is to be taken, to be given to each
Holder of such Preferred Securities in the manner set forth in the applicable
Trust Agreement (Section 6.02).
 
    No vote or consent of the Holders of Preferred Securities of a particular
series will be required for the Issuer to redeem and cancel Preferred Securities
of such series in accordance with the applicable Trust Agreements.
 
    Notwithstanding that Holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities that are owned by MidAmerican Energy, the Property Trustee or any
affiliate of MidAmerican Energy or the Property Trustee, shall, for purposes of
such vote or consent, be treated as if they were not outstanding.
 
                                       13
<PAGE>
AMENDMENTS
 
    Either Trust Agreement may be amended from time to time by the applicable
Issuer (on approval of a majority of the Administrative Trustees) and
MidAmerican Energy, without the consent of any Holders of Trust Securities, (i)
to cure any ambiguity, correct or supplement any provision therein which may be
inconsistent with any other provision therein, or to make any other provisions
with respect to matters or questions arising under the applicable Trust
Agreement, which shall not be inconsistent with the other provisions of the
applicable Trust Agreement, or (ii) to modify, eliminate or add to any
provisions of the applicable Trust Agreement to such extent as shall be
necessary to ensure that the Issuer will be classified for United States federal
income tax purposes as a grantor trust at any time that any Trust Securities are
outstanding or to ensure the Issuer's exemption from the status of an
"investment company" under the Investment Company Act of 1940, as amended (the
"1940 Act"); provided, however, that, except in the case of clause (ii), such
action shall not adversely affect in any material respect the interests of any
Holder of Trust Securities issued pursuant to such Trust Agreement and, in the
case of clause (i), any amendments of such Trust Agreement shall become
effective when notice thereof is given to the Holders of Trust Securities issued
thereunder.
 
    Except as provided below, any provision of either Trust Agreement may be
amended by the Administrative Trustees and MidAmerican Energy with (i) the
consent of Holders of Trust Securities issued pursuant to such Trust Agreement
representing not less than a majority in liquidation preference of such Trust
Securities then outstanding and (ii) receipt by the applicable Trustee of an
opinion of counsel to the effect that such amendment or the exercise of any
power granted to such Trustee in accordance with such amendment will not affect
the Issuer's status as a grantor trust for United States federal income tax
purposes or affect the Issuer's exemption from status of an "investment company"
under the 1940 Act.
 
    Without the consent of each affected Holder of Trust Securities, a Trust
Agreement may not be amended to (i) change the amount or timing of any
distribution with respect to the Trust Securities issued pursuant to such Trust
Agreement or otherwise adversely affect the amount of any distribution required
to be made in respect of such Trust Securities as of a specified date or (ii)
restrict the right of a Holder of such Trust Securities to institute suit for
the enforcement of any such payment on or after such date.
 
REMOVAL OF PROPERTY TRUSTEE
 
    Unless an Event of Default under the Indenture shall have occurred and be
continuing, the Property Trustee may be removed at any time by act of
MidAmerican Energy as the Holder of the Common Securities. If an Event of
Default under the Indenture has occurred and is continuing, the Property Trustee
may be removed at such time by act of the Holders of Preferred Securities having
a majority of the liquidation preference of the Preferred Securities then
outstanding. In no event will the Holders of the Preferred Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in MidAmerican Energy as the Holder of the
Common Securities. No resignation or removal of the Property Trustee and no
appointment of a successor trustee shall be effective until the acceptance of
appointment by the successor Property Trustee in accordance with the provisions
of the Trust Agreements. (Section 8.10).
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
    Unless an Event of Default under the Indenture shall have occurred and be
continuing, at any time or times, for the purpose of meeting the legal
requirements of the Trust Indenture Act or of any jurisdiction in which any part
of the Trust Property (as defined in the applicable Trust Agreement) may at the
time be located, the Holder of the Common Securities and the Property Trustee
shall have power to appoint, and upon the written request of the Property
Trustee, MidAmerican Energy, as Depositor, shall for such purpose join with the
Property Trustee in the execution, delivery and performance of all
 
                                       14
<PAGE>
instruments and agreements necessary or proper to appoint, one or more persons
approved by the Property Trustee either to act as co-trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to act as
separate trustee of any such property, in either case with such powers as may be
provided in the instrument of appointment, and to vest in such person or persons
in such capacity, any property, title, right or power deemed necessary or
desirable, subject to the provisions of the applicable Trust Agreement. If
MidAmerican Energy, as Depositor, does not join in such appointment within 15
days after the receipt by it of a request so to do, or in case an Event of
Default under the Indenture has occurred and is continuing, the Property Trustee
alone shall have the power to make such appointment. (Section 8.09).
 
FORM, EXCHANGE AND TRANSFER
 
    Preferred Securities will be issuable only in fully registered form each
having a liquidation preference amount of $25 and any integral multiple thereof.
 
    At the option of the Holder, subject to the terms of the applicable Trust
Agreement, Preferred Securities of any series will be exchangeable for other
Preferred Securities of such series, of any authorized denomination and of like
tenor and aggregate liquidation preference.
 
    Subject to the terms of the applicable Trust Agreement, Preferred Securities
of any series may be presented for exchange as provided above or for
registration of transfer (duly endorsed or accompanied by a duly executed
instrument of transfer) at the office of the Transfer Agent designated for such
purpose. The Administrative Trustees may designate MidAmerican Energy as
Transfer Agent and as Registrar. No service charge will be made for any
registration of transfer or exchange of Preferred Securities, but MidAmerican
Energy may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. Such transfer or exchange
will be effected upon the Transfer Agent being satisfied with the documents of
title and identity of the person making the request. The Administrative Trustees
may at any time designate additional Transfer Agents or rescind the designation
of any Transfer Agent or approve a change in the office through which any
Transfer Agent acts.
 
    An Issuer will not be required to (i) issue, register the transfer of, or
exchange any of its Preferred Securities during a period beginning at the
opening of business 15 calendar days before the day of mailing of a notice of
redemption of any of its Preferred Securities called for redemption and ending
at the close of business on the day of such mailing or (ii) register the
transfer of or exchange any Preferred Securities so selected for redemption, in
whole or in part, except the unredeemed portion of any such Preferred Securities
being redeemed in part. (Section 5.04).
 
REGISTRAR AND TRANSFER AGENT
 
    Initially, The First National Bank of Chicago will act as Registrar and
Transfer Agent for the Preferred Securities.
 
    Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of either Issuer, but upon payment (with the giving of
such indemnity as the Issuer or MidAmerican Energy may require) in respect of
any tax or other governmental charges which may be imposed in relation to it.
 
    The Issuers will not be required to register or cause to be registered any
transfer of Preferred Securities after they have been called for redemption
except the unredeemed portion of any Preferred Securities being redeemed in
part. (Section 5.04).

CONCERNING THE PROPERTY TRUSTEE
 
    MidAmerican Energy maintains deposit accounts and conducts other banking
transactions with the Property Trustee in the ordinary course of its businesses.
The Property Trustee also acts as the Guarantee Trustee under the Guarantee, the
Debenture Trustee under the Indenture and under another indenture under which
medium-term notes of MidAmerican Energy are or may become outstanding.
 
MISCELLANEOUS
 
    Application will be made to list the Preferred Securities on the New York
Stock Exchange.
 
    The Delaware Trustee will act as the resident trustee in the state of
Delaware and will have no other significant duties. The Property Trustee will
hold the Debentures on behalf of the Issuers and will maintain a payment account
with respect to the Trust Securities, and will also act as trustee under the
Trust Agreements for the purposes of the Trust Indenture Act. See "-- Events of
Default; Notice." The Administrative Trustees will administer the day to day
operations of the Issuers. See "-- Voting Rights."
 
    The Administrative Trustees are authorized and directed to conduct the
affairs of each Issuer and to operate each Issuer so that neither Issuer will be
deemed to be an "investment company" required to be registered under the 1940
Act or classified other than as a grantor trust for United States federal income
tax purposes and so that the Debentures will be treated as indebtedness of
MidAmerican Energy for United States federal income tax purposes. In this
connection, the Administrative Trustees and MidAmerican Energy are authorized to
take any action, not inconsistent with applicable law, the certificate of trust
of either Issuer or the Trust Agreements, that the Administrative Trustees and
MidAmerican Energy determine in their discretion to be necessary or desirable
for such purposes, as long as such action does not materially adversely affect
the interests of the Holders of the Preferred Securities. (Section 2.07(d)).
 
    Holders of the Preferred Securities have no preemptive or similar rights.
 
                                       16
<PAGE>
                         DESCRIPTION OF THE GUARANTEES
 
    Set forth below is a summary of information concerning the Guarantees that
will be executed and delivered by MidAmerican Energy for the benefit of the
Holders from time to time of Preferred Securities of each series. Each Guarantee
will be qualified as an indenture under the Trust Indenture Act. The First
National Bank of Chicago will act as Guarantee Trustee under each Guarantee for
the purposes of compliance with the Trust Indenture Act. The terms of each
Guarantee will be those set forth in such Guarantee and those made part of such
Guarantee by the Trust Indenture Act. This summary does not purport to be
complete and is subject in all respects to the provisions of, and is qualified
in its entirety by reference to, the Guarantees, a form of which is filed as an
exhibit to the Registration Statement of which this Prospectus forms a part, and
the Trust Indenture Act. The Guarantee Trustee will hold each Guarantee for the
benefit of the Holders of the corresponding Preferred Securities.
 
GENERAL
 
    MidAmerican Energy will fully and unconditionally agree, to the extent set
forth herein, to pay the Guarantee Payments (as defined herein) in full to the
Holders of the Preferred Securities of a particular series (except to the extent
paid by or on behalf of the applicable Issuer), as and when due, regardless of
any defense, right of set-off or counterclaim that the applicable Issuer may
have or assert. The following payments with respect to the Preferred Securities,
to the extent not paid by or on behalf of the applicable Issuer (the "Guarantee
Payments"), will be subject to the related Guarantee (without duplication): (i)
any accrued and unpaid Distributions required to be paid on the Preferred
Securities of such series, to the extent the Property Trustee has available in
the payment account for such Issuer sufficient funds to make such payment, (ii)
the Redemption Price with respect to any Preferred Securities called for
redemption by the applicable Issuer, to the extent the Property Trustee has
available in the payment account for such Issuer sufficient funds to make such
payment and (iii) upon a voluntary or involuntary dissolution, winding-up or
termination of the applicable Issuer (other than in connection with a redemption
of all of the Preferred Securities), the lesser of (a) the aggregate of the
liquidation preference amount and all accrued and unpaid Distributions on such
Preferred Securities to the date of payment and (b) the amount of assets of such
Issuer remaining available for distribution to Holders of such Preferred
Securities in liquidation of such Issuer. MidAmerican Energy's obligation to
make a Guarantee Payment may be satisfied by direct payment of the required
amounts by MidAmerican Energy to the Holders of such Preferred Securities or by
causing the applicable Issuer to pay such amounts to such Holders.
 
    Each Guarantee will be a guarantee with respect to the Preferred Securities
issued by the applicable Issuer from the time of issuance of such Preferred
Securities, but will not apply to (i) any payment of Distributions if and to the
extent that such Issuer does not have funds available to make such payments, or
(ii) collection of payment. If MidAmerican Energy does not make interest
payments on the Debentures held by an Issuer, such Issuer will not have funds
available to pay Distributions on the Preferred Securities. The Guarantees will
rank subordinate and junior in right of payment to all Senior Indebtedness
(except those made PARI PASSU by their terms). See "Status of the Guarantees."
MidAmerican Energy will agree in the Agreements as to Expenses and Liabilities
(the "Expense Agreements"), a form of which is filed as an exhibit to the
Registration Statement of which this Prospectus forms a part, to provide funds
to the Issuers as needed to pay obligations of the Issuers to parties other than
Holders of Trust Securities. The Debentures and the Guarantees, together with
the obligations of MidAmerican Energy with respect to the Preferred Securities
under the Indenture, the Trust Agreements, the Guarantees and the Expense
Agreements constitute full and unconditional guarantees of the Preferred
Securities by MidAmerican Energy. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such
guarantees. It is only the combined operation of these documents that has the
effect of providing full and unconditional guarantees by MidAmerican Energy of
the Preferred Securities.

AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes that do not materially adversely affect
the rights of Holders of Preferred Securities of a particular Issuer (in which
case no vote will be required), the terms of a Guarantee may be changed only
with the prior approval of the Holders of such Preferred Securities having at
least 66 2/3% of the liquidation preference amount of such outstanding Preferred
Securities. All guarantees and agreements contained in any Guarantee shall bind
the successors, assigns, receivers, trustees and representatives of MidAmerican
Energy and shall inure to the benefit of the Holders of the corresponding
Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
    An event of default under a Guarantee will occur upon the failure of
MidAmerican Energy to perform any of its payment obligations thereunder. The
Holders of Preferred Securities of an Issuer having a majority of the
liquidation preference of such Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of such Guarantee or to direct the exercise of
any trust or power conferred upon the Guarantee Trustee under such Guarantee.
 
    Any Holder of Preferred Securities may institute a legal proceeding directly
against MidAmerican Energy to enforce its rights under a Guarantee without first
instituting a legal proceeding against the applicable Issuer, the Guarantee
Trustee or any other person or entity.
 
    MidAmerican Energy, as Guarantor, will be required to provide annually to
the Guarantee Trustee a statement as to the performance by MidAmerican Energy of
certain of its obligations under the Guarantees and as to any default in such
performance and an officer's certificate as to MidAmerican Energy's compliance
with all conditions under the Guarantees.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
    The Guarantee Trustee, prior to the occurrence of a default by MidAmerican
Energy in performance of a Guarantee, has undertaken to perform only such duties
as are specifically set forth in the Guarantees and, after default with respect
to any Guarantee, must exercise the same degree of care as a prudent individual
would exercise in the conduct of his or her own affairs. Subject to this
provision, the Guarantee Trustee is under no obligation to exercise any of the
powers vested in it by a Guarantee at the request of any Holder of Preferred
Securities of a particular series unless it is offered reasonable indemnity
against the costs, expenses and liabilities that might be incurred thereby. See
"Description of the Preferred Securities -- Concerning the Property Trustee."
 
TERMINATION OF THE GUARANTEES
 
    A Guarantee will terminate and be of no further force and effect upon full
payment of the Redemption Price of all related Preferred Securities, the
distribution of Debentures to Holders of such Preferred Securities in exchange
for all of such Preferred Securities or full payment of the amounts payable upon
liquidation of the related Issuer. Each Guarantee will continue to be effective
or will be reinstated, as the case may be, if at any time any such Holder of
Preferred Securities must restore payment of any sums paid under such Preferred
Securities or the related Guarantee.
 
STATUS OF THE GUARANTEES
 
    Each Guarantee will constitute an unsecured obligation of MidAmerican Energy
and will rank (i) subordinate and junior in right of payment to all liabilities
of MidAmerican Energy (except liabilities that may be made PARI PASSU by their
terms), (ii) PARI PASSU with the most senior preferred or preference stock now
or hereafter issued by MidAmerican Energy and with any guarantee now or
hereafter entered into
 
                                       18
<PAGE>
by MidAmerican Energy in respect of any preferred or preference stock of any
affiliate of MidAmerican Energy and (iii) senior to MidAmerican Energy's common
stock. Each Trust Agreement provides that each Holder of Preferred Securities
issued thereunder agrees, by acceptance thereof, to the subordination provisions
and other terms of the related Guarantee.
 
    Each Guarantee will rank PARI PASSU with each other Guarantee and with any
similar guarantees issued by the Guarantor on behalf of the holders of Preferred
Securities issued by any other Issuer holding Debentures issued under the
Indenture.
 
    Each Guarantee will constitute a guarantee of payment and not of collection
(i.e., the guaranteed party may institute a legal proceeding directly against
the Guarantor to enforce its rights under the applicable Guarantee without first
instituting a legal proceeding against any other person or entity).
 
GOVERNING LAW
 
    Each Guarantee will be governed by and construed in accordance with the laws
of the State of New York.
 
                         DESCRIPTION OF THE DEBENTURES
 
    Set forth below is a description of certain terms of the Debentures which
each of the Issuers will hold as trust assets. The following description does
not purport to be complete and is qualified in its entirety by reference to the
description in the Indenture, as supplemented by the Supplemental Indenture
creating each series of Debentures, between MidAmerican Energy and the Trustee
with respect to the Debentures (the "Debenture Trustee"), the forms of which are
filed as exhibits to the Registration Statement of which this Prospectus forms a
part, and to the Trust Indenture Act. Whenever particular provisions or defined
terms in the Indenture are referred to herein, such provisions or defined terms
are incorporated by reference herein. Section references used herein are
references to provisions of the Indenture unless otherwise noted.
 
    The Indenture provides for the issuance of Debentures in an unlimited amount
from time to time. Each series of Debentures will constitute a separate series
under the Indenture, will be in a principal amount equal to the aggregate stated
Liquidation Amount of the corresponding Preferred Securities plus MidAmerican
Energy's concurrent investment in the Common Securities and will rank PARI PASSU
with all other series of Debentures.
 
GENERAL
 
    Each series of Debentures will be limited in aggregate principal amount to
the sum of the aggregate liquidation preference amount of the Preferred
Securities of the applicable Issuer and the consideration paid by MidAmerican
Energy for the Common Securities of such Issuer and will have terms similar to
the terms of such Preferred Securities. The Debentures will be unsecured,
subordinated obligations of MidAmerican Energy which rank junior to all of
MidAmerican Energy's Senior Indebtedness (as defined under "--Subordination"
below). Each series of Debentures will bear interest at the same rate, payable
at the same times, as the distributions payable on the corresponding series of
Trust Securities, and will have a maturity and redemption provisions correlative
to those of such Trust Securities. The amounts payable as principal and interest
on each series of Debentures will be sufficient to provide for payment of
Distributions payable on the corresponding series of Trust Securities.
 
    Each series of Debentures may be distributed pro rata to the holders of the
corresponding series of Trust Securities in connection with the dissolution of
the applicable Issuer upon the occurrence of certain events described in the
Prospectus Supplement relating to such Trust Securities. If Debentures are
distributed to Holders of Preferred Securities in connection with the
dissolution of an Issuer, such
 
                                       19
<PAGE>
Debentures will be issued in fully registered certificated form in denominations
of $25 and integral multiples thereof and may be transferred or exchanged at the
offices described below.
 
    Payments of principal of and interest on Debentures will be payable, the
transfer of Debentures will be registrable, and Debentures will be exchangeable
for Debentures of the same series with other denominations and a like aggregate
principal amount, at the office or agency of the Company in [The City of New
York]; provided that payment of interest may be made at the option of
MidAmerican Energy by check mailed to the address of the persons entitled
thereto and that the payment in full of principal with respect to any Debenture
will be made only upon surrender of such Debenture to the Debenture Trustee.
 
OPTIONAL REDEMPTION
 
    MidAmerican Energy will have the right, at any time and from time to time on
or after the date set forth in the applicable Supplemental Indenture, to redeem
any series of Debentures, in whole or in part, at a redemption price as set
forth in such Supplemental Indenture, together with any accrued but unpaid
interest, including Additional Interest Attributable to Taxes (as defined
below), if any, to the Redemption Date.
 
    Except as otherwise specified in the applicable Prospectus Supplement, if a
Special Event shall occur and be continuing, MidAmerican Energy shall have the
right to redeem any series of Debentures, in whole but not in part, at a
redemption price equal to 100% of the principal amount of such series of
Debentures then outstanding plus any accrued and unpaid interest, including
Additional Interest Attributable to Taxes, if any, to the Redemption Date.
 
    For so long as an Issuer is the Holder of all the outstanding Debentures of
a particular series, the proceeds of any such redemption will be used by such
Issuer to redeem its Preferred Securities and Common Securities in accordance
with their terms. MidAmerican Energy may not redeem any series of Debentures in
part unless all accrued and unpaid interest (including any Additional Interest
Attributable to Taxes) has been paid in full on all outstanding Debentures of
such series for all quarterly interest periods terminating on or prior to the
date of redemption.
 
    Any optional redemption of a series of Debentures shall be made upon not
less than 30 nor more than 60 days' notice from the Debenture Trustee to the
Holders of such Debentures, as provided in the Indenture. All notices of
redemption shall state the Redemption Date; the redemption price plus accrued
and unpaid distributions; if less than all of such Debentures are to be
redeemed, the identification of those to be redeemed and the portion of the
principal amount of any such Debentures to be redeemed in part; that on the
Redemption Date, subject to the Debenture Trustee's receipt of the redemption
monies, the redemption price plus accrued and unpaid distributions will become
due and payable upon each such Debenture to be redeemed and that interest
thereon will cease to accrue on and after said date; and the place or places
where such securities are to be surrendered for payment of the redemption price
plus accrued and unpaid distributions.
 
INTEREST
 
    The Debentures of a particular series will bear interest at the rate per
annum set forth in the applicable Supplemental Indenture and from the date
specified therein. Such interest is payable quarterly in arrears on March 1,
June 1, September 1 and December 1 of each year (each, an "Interest Payment
Date"), to the person in whose name such Debentures are registered, by the close
of business on the Business Day 15 days preceding such Interest Payment Date. It
is anticipated that each Issuer will be the sole Holder of a particular series
of Debentures.
 
    The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months and for any period shorter than a full
month, on the basis of the actual number of
 
                                       20
<PAGE>
days elapsed. (Section 310).  In the event that any date on which interest is
payable on the Debentures is not a Business Day, then payment of the interest
payable on such date will be made on the next succeeding day which is a Business
Day and without any interest or other payment in respect of any such delay,
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on the date the payment was originally
payable. (Section 113).
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
    MidAmerican Energy shall have the right, at any time and from time to time
during the term of any of the Debentures, to extend the interest payment period
on such Debentures to a period not exceeding 20 consecutive quarters during
which period interest will be compounded quarterly. At the end of an Extension
Period, MidAmerican Energy must pay all interest then accrued and unpaid
(together with interest thereon at the rate specified for such Debentures
compounded quarterly, to the extent permitted by applicable law). However,
during any such Extension Period, MidAmerican Energy may not, and may not permit
any of its subsidiaries to, (i) declare or pay any dividends or distributions
on, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of MidAmerican Energy's capital stock or (ii) make any payment of principal
of, interest or premium, if any, on, or repay, repurchase or redeem any debt
securities of MidAmerican Energy (including other Debentures) that rank PARI
PASSU with or junior in interest to the series of Debentures to which such
Extension Period applies, or make any guarantee payments with respect to any
guarantee by MidAmerican Energy of the debt securities of any of its
subsidiaries if such guarantee ranks PARI PASSU or junior in interest to such
Series of Debentures (other than (a) dividends or distributions in common stock
of MidAmerican Energy, (b) payments under any Guarantee, and (c) purchases of
common stock related to the issuance of common stock under any of MidAmerican
Energy's benefit plans for its directors, officers or employees). This covenant
effectively requires that any Extension Period with respect to payment of
interest on a series of Debentures will apply to all other series of Debentures.
Prior to the termination of any such Extension Period, MidAmerican Energy may
further extend the interest payment period, provided that such Extension Period
together with all such previous and further extensions thereof shall not exceed
20 consecutive quarters at any one time or extend beyond the Maturity Date of
the Debentures in question. Upon the termination of any such Extension Period
and the payment of all amounts then due, MidAmerican Energy may select a new
Extension Period, subject to the above requirements. No interest shall be due
and payable during an Extension Period, except at the end thereof; provided,
however, that Additional Interest Attributable to Taxes, if any, shall not be
deferred and shall be payable on the relevant Interest Payment Date. MidAmerican
Energy shall give the Debenture Trustee and the Administrative Trustees of the
Issuer notice of its election of an Extension Period no less than 15 Business
Days prior to the later of (i) the Regular Record Date next preceding the first
Interest Payment Date on which a distribution would occur but for such election
and (ii) five Business Days prior to such Interest Payment Date. Upon receipt of
any such notice, the Debenture Trustee shall give written notice of the
Company's election by mail to the Holders of the affected series of Preferred
Securities not less than 10 Business Days prior to such Interest Payment Date.
MidAmerican Energy also shall make a public announcement of such election in
accordance with New York Stock Exchange Rules not less than five Business Days
prior to such Regular Record Date. (Section 311).
 
ADDITIONAL INTEREST ATTRIBUTABLE TO TAXES
 
    So long as Preferred Securities of any series remain outstanding, if the
Issuer thereof would be required to pay, with respect to its income derived from
the interest payments on the corresponding series of Debentures, any amounts for
or on account of any taxes, duties, assessments or governmental charges of
whatever nature imposed by the United States, or any other taxing authority,
then, in any such case, MidAmerican Energy will pay as interest on such
Debentures such additional interest (the "Additional Interest Attributable to
Taxes") as may be necessary in order that the net amounts received and
 
                                       21
<PAGE>
retained by such Issuer after the payment of such taxes, duties, assessments or
governmental charges shall result in such Issuer having such funds as it would
have had in the absence of the payment of such taxes, duties, assessments or
governmental charges. (Section 312).
 
EXTENSION OR ADJUSTMENT OF STATED MATURITY
 
    If provided in the applicable Prospectus Supplement, MidAmerican Energy
shall have the right to (i) extend or shorten the maturity of any series of
Debentures at the time that MidAmerican Energy exercises its right to elect to
liquidate the related Issuer and cause such Debentures to be distributed to the
Holders of such Issuer's Preferred Securities and Common Securities in
liquidation of the Issuer (see "Description of the Preferred Securities --
Termination of an Issuer and Distribution of Debentures"), and (ii) extend the
maturity of any series of Debentures at any time; provided that in the case of
both (i) and (ii) above, it can extend the maturity only if certain conditions
specified in the applicable Prospectus Supplement are met at the time such
election is made and at the time of such extension.
 
DEFEASANCE
 
    The principal amount of any series of Debentures issued under the Indenture
will be deemed to have been paid for purposes of the Indenture and the entire
indebtedness of MidAmerican Energy in respect thereof will be deemed to have
been satisfied and discharged, if there shall have been irrevocably deposited
with the Debenture Trustee or any paying agent, in trust: (a) money in an amount
which will be sufficient, or (b) in the case of a deposit made prior to the
maturity of such series of Debentures, Government Obligations (as defined
herein), which do not contain provisions permitting the redemption or other
prepayment thereof at the option of the issuer thereof, the principal of and the
interest on which when due, without any regard to reinvestment thereof, will
provide moneys which, together with the money, if any, deposited with or held by
the Debenture Trustee, will be sufficient, or (c) a combination of (a) and (b)
which will be sufficient, to pay when due the principal of and premium, if any,
and interest, if any, due and to become due on the Debentures of such series
that are outstanding. For this purpose, Government Obligations include direct
obligations of, or obligations unconditionally guaranteed by, the United States
of America entitled to the benefit of the full faith and credit thereof and
certificates, depositary receipts or other instruments which evidence a direct
ownership interest in such obligations or in any specific interest or principal
payments due in respect thereof. (Section 701).
 
    Under current United States federal income tax law any deposit contemplated
in the preceding paragraph would be treated as a taxable exchange of such
outstanding Debentures for an issue of obligations of an Issuer or a direct
interest in the cash and securities held by an Issuer. In that case, Holders of
such outstanding Debentures would recognize a gain or loss for federal income
tax purposes, as if their share of such Issuer obligations or the cash or
securities deposited, as the case may be, had actually been received by them in
exchange for their Debentures. In addition, such Holders thereafter would be
required to include in income a share of the income, gain or loss of such
Issuer. The amount so required to be included in income could be different from
the amount that would be includable in the absence of such deposit. Prospective
investors are urged to consult their own tax advisors as to the specific
consequences to them of any such deposit.
 
SUBORDINATION
 
    The Debentures will be subordinate and junior in right of payment to all
Senior Indebtedness of MidAmerican Energy to the extent provided in the
Indenture. No payment of principal of (including redemption and sinking fund
payments), or interest on, the Debentures may be made (i) upon the occurrence of
certain events of bankruptcy, insolvency or reorganization, (ii) if any Senior
Indebtedness is not paid when due, (iii) if any other default has occurred
pursuant to which the Holders of Senior Indebtedness have accelerated the
maturity thereof and with respect to (ii) and (iii), such default has not been
cured or waived, or (iv) if the maturity of any series of Debentures has been
accelerated, because
 
                                       22
<PAGE>
of an event of default with respect thereto, which remains uncured. Upon any
payment or distribution of assets of MidAmerican Energy to creditors upon any
dissolution, winding-up, liquidation or reorganization, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
principal of, and premium, if any, and interest due or to become due on, all
Senior Indebtedness must be paid in full before the Holders of the Debentures
are entitled to receive or retain any payment thereon. (Section 1502). Subject
to the prior payment of all Senior Indebtedness, the rights of the Holders of
the Debentures will be subrogated to the rights of the Holders of Senior
Indebtedness to receive payments or distributions applicable to Senior
Indebtedness until all amounts owing on the Debentures are paid in full.
(Section 1504).
 
    The term Senior Indebtedness is defined in the Indenture to mean all
obligations (other than non-recourse obligations and the indebtedness issued
under the Indenture) of, or guaranteed or assumed by, MidAmerican Energy for
borrowed money, including both senior and subordinated indebtedness for borrowed
money (other than the Debentures), or for the payment of money relating to any
lease which is capitalized on the consolidated balance sheet of MidAmerican
Energy and its subsidiaries in accordance with generally accepted accounting
principles as in effect from time to time, or evidenced by bonds, debentures,
notes or other similar instruments, and in each case, amendments, renewals,
extensions, modifications and refundings of any such indebtedness or
obligations, whether existing as of the date of the Indenture or subsequently
incurred by MidAmerican Energy unless, in the case of any particular
indebtedness, renewal, extension or refunding, the instrument creating or
evidencing the same or the assumption or guarantee of the same expressly
provides that such indebtedness, renewal, extension or refunding is not superior
in right of payment to or is PARI PASSU with the Debentures; provided that
MidAmerican Energy's obligations under the Guarantees shall not be deemed to be
Senior Indebtedness. (Section 101).
 
    The Indenture does not limit the aggregate amount of Senior Indebtedness
that may be issued. As of September 30, 1996, MidAmerican Energy had
approximately $1.2 billion principal amount of Senior Indebtedness.
 
CONSOLIDATION, MERGER, AND SALE OF ASSETS
 
    Under the terms of the Indenture, MidAmerican Energy may not consolidate
with or merge into any other entity or convey, transfer or lease its properties
and assets substantially as an entirety to any entity, unless (i) the
corporation formed by such consolidation or into which MidAmerican Energy is
merged or the entity which acquires by conveyance or transfer, or which leases,
the property and assets of MidAmerican Energy substantially as an entirety shall
be an entity organized and validly existing under the laws of any domestic
jurisdiction and such entity expressly assumes (by a Supplemental Indenture)
MidAmerican Energy's obligations on all Debentures under the Indenture, (ii)
immediately after giving effect to the transaction, 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, and (iii) MidAmerican Energy
shall have delivered to the Debenture Trustee an Officer's Certificate and an
Opinion of Counsel as provided in the Indenture. (Section 1101).
 
EVENTS OF DEFAULT
 
    Each of the following will constitute an Event of Default under the
Indenture with respect to any series of Debentures: (a) failure to pay any
interest on the Debentures of such series within 30 days after the same becomes
due and payable, provided that deferral of payment during an Extension Period
will not constitute an Event of Default; (b) failure to pay principal or
premium, if any, on the Debentures of such series when due and payable; (c)
failure to perform, or breach of, any other covenant or warranty of MidAmerican
Energy in the Indenture (other than a covenant or warranty of MidAmerican Energy
in the Indenture solely for the benefit of one or more series of Debentures
other than such series) for 60 days after written notice to MidAmerican Energy
by the Debenture Trustee, or to MidAmerican Energy and the
 
                                       23
<PAGE>
Debenture Trustee by the Holders of at least 33% in principal amount of the
Debentures of such series outstanding under the Indenture as provided in the
Indenture (provided that such 60 day period shall be automatically extended if
corrective action is initiated by MidAmerican Energy within such period and is
being diligently pursued); (d) the entry by a court having jurisdiction in the
premises of (1) a decree or order for relief in respect of MidAmerican Energy in
an involuntary case or proceeding under any applicable Federal or state
bankruptcy, insolvency, reorganization or other similar law or (2) a decree or
order adjudging MidAmerican Energy bankrupt or insolvent, or approving as
properly filed a petition by one or more Persons other than MidAmerican Energy
seeking reorganization, arrangement, adjustment or composition of or in respect
of MidAmerican Energy under any applicable Federal or state law, or appointing a
custodian, receiver, liquidator, assignee, trustee, sequestrator or other
similar official for MidAmerican Energy or for any substantial part of its
property, or ordering the winding up or liquidation of its affairs, and any such
decree or order for relief or any such other decree or order shall have remained
unstayed and in effect for a period of 90 consecutive days; and (e) the
commencement by MidAmerican Energy of a voluntary case or proceeding under any
applicable Federal or state bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated bankrupt or
insolvent, or the consent by it to the entry of a decree or order for relief in
respect of MidAmerican Energy in a case or other similar proceeding or to the
commencement of any bankruptcy or insolvency case or proceeding against it under
any applicable Federal or state law or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable Federal or
state law, or the consent by it to the filing of such petition or to the
appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or similar official of MidAmerican Energy or of
any substantial part of its property, or the making by it of an assignment for
the benefit of creditors, or the admission by it in writing of its inability to
pay its debts generally as they become due, or the authorization of such action
by the Board of Directors. (Section 801).
 
    An Event of Default with respect to the Debentures of a particular series
may not necessarily constitute an Event of Default with respect to Debentures of
any other series issued under the Indenture.
 
    If an Event of Default with respect to Debentures of any series at the time
outstanding occurs and is continuing, then either the Debenture Trustee or the
Holders of 33% in principal amount of the outstanding Debentures of such series
may declare the principal of all of the Debentures of such series and interest
accrued thereon to be due and payable immediately (subject to the subordination
provisions of the Indenture), and, should the Debenture Trustee or such Holders
of Debentures fail to make such declaration, the Holders of at least 33% in
aggregate liquidation preference of the outstanding shares (if any) of the
corresponding series of Preferred Securities shall have such right. (Section
802).
 
    At any time after the declaration of acceleration with respect to the
Debentures of any series has been made and before a judgment or decree for
payment of the money due has been obtained, the Event or Events of Default
giving rise to such declaration of acceleration will, without further act, be
deemed to have been waived, and such declaration and its consequences will,
without further act, be deemed to have been rescinded and annulled, if:
 
    (a) MidAmerican Energy has paid or deposited with the Debenture Trustee a
       sum sufficient to pay
 
       (1) all overdue interest on all Debentures of such series;
 
       (2) the principal of and premium, if any, on any Debentures of such
           series which have become due otherwise than by such declaration of
           acceleration and interest thereon at the rate or rates prescribed
           therefor in such Debentures;
 
       (3) interest upon overdue interest at the rate or rates prescribed
           therefor in such Debentures, to the extent that payment of such
           interest is lawful; and
 
       (4) all amounts due to the Debenture Trustee under the Indenture; and
 
                                       24
<PAGE>
    (b) any other Event or Events of Default with respect to Debentures of such
       series, other than the nonpayment of the principal of the Debentures of
       such series which has become due solely by such declaration of
       acceleration, have been cured or waived as provided in the Indenture.
       (Section 802).
 
    Subject to the provisions of the Indenture relating to the duties of the
Debenture Trustee in case an Event of Default shall occur and be continuing, the
Debenture Trustee will be under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any of the Holders of
the Debentures, unless such Holders shall have offered to the Debenture Trustee
reasonable indemnity. (Section 903). If an Event of Default has occurred and is
continuing in respect of a series of Debentures, subject to such provisions for
the indemnification of the Debenture Trustee, the Holders of a majority in
principal amount of the outstanding Debentures of such series will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Debenture Trustee, or exercising any trust or power
conferred on the Debenture Trustee, with respect to the Debentures of such
series; provided, however, that if an Event of Default occurs and is continuing
with respect to more than one series of Debentures, the Holders of a majority in
aggregate principal amount of the outstanding Debentures of all such series,
considered as one class, will have the right to make such direction, and not the
Holders of the Debentures of any one of such series; and provided, further, that
such direction will not be in conflict with any rule of law or with the
Indenture. (Section 812).
 
    No Holder of Debentures of any series will have any right to institute any
proceeding with respect to the Indenture, or for the appointment of a receiver
or a trustee, or for any other remedy thereunder unless (i) such Holder has
previously given to the Debenture Trustee written notice of a continuing Event
of Default with respect to the Debentures of such series, (ii) the Holders of
not less than a majority in aggregate principal amount of the outstanding
Debentures of all series in respect of which an Event of Default shall have
occurred and be continuing, considered as one class, have made written request
to the Debenture Trustee, and such Holder or Holders have offered reasonable
indemnity to the Debenture Trustee to institute such proceeding in respect of
such Event of Default in its own name as trustee and (iii) the Debenture Trustee
has failed to institute any proceeding, and has not received from the Holders of
a majority in aggregate principal amount of the outstanding Debentures of such
series a direction inconsistent with such request, within 60 days after such
notice, request and offer. (Section 807). However, such limitations do not apply
to (a) a suit instituted by a Holder of a Debenture for the enforcement of
payment of the principal of or any premium or interest on such Debenture on or
after the applicable due date specified in such Debenture, or (b) a Direct
Action by a Holder of Preferred Securities as described under "-- Enforcement of
Certain Rights by Holders of Preferred Securities." (Section 808).
 
    MidAmerican Energy will be required to furnish to the Debenture Trustee
annually a statement by an appropriate officer as to such officer's knowledge of
MidAmerican Energy's compliance with all conditions and covenants under the
Indenture, such compliance to be determined without regard to any period of
grace or requirement of notice under the Indenture. (Section 606).
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
    If an Event of Default with respect to a series of Debentures has occurred
and is continuing and such event is attributable to the failure of MidAmerican
Energy to pay interest or principal on such Debentures on the date such interest
or principal is otherwise payable, a Holder of the corresponding series of
Preferred Securities may institute a legal proceeding directly against
MidAmerican Energy for enforcement of payment to such Holder of the principal of
or interest on such Debentures having a principal amount equal to the aggregate
Liquidation Amount of the related Preferred Securities of such holder (a "Direct
Action"). MidAmerican Energy may not amend the Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of the Holders
of all of the Preferred Securities. If the right to bring a Direct Action is
removed, the applicable Issuer may become subject to the reporting
 
                                       25
<PAGE>
obligations under the Securities Exchange Act of 1934, as amended. MidAmerican
Energy shall have the right under the Indenture to set-off any payment made to a
Holder of Preferred Securities by MidAmerican Energy in connection with a Direct
Action. The Holders of Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the related Debentures.
 
MODIFICATION AND WAIVER
 
    Without the consent of any Holder of Debentures, MidAmerican Energy and the
Debenture Trustee may amend or supplement the Indenture for any of the following
purposes: (a) to evidence the assumption by any permitted successor to
MidAmerican Energy of the covenants of MidAmerican Energy in the Indenture and
the Debentures; or (b) to add one or more covenants of MidAmerican Energy or
other provisions for the benefit of the Holders of outstanding Debentures or to
surrender any right or power conferred upon MidAmerican Energy by the Indenture;
or (c) to add any additional Events of Default with respect to outstanding
Debentures; or (d) to change or eliminate any provision of the Indenture or to
add any new provision to the Indenture, provided that if such change,
elimination or addition will adversely affect the interests of the Holders of
Debentures of any series in any material respect, such change, elimination or
addition will become effective with respect to such series only (1) when the
consent of the Holders of Debentures of such series has been obtained in
accordance with the Indenture, or (2) when no Debentures of such series remain
outstanding under the Indenture; or (e) to provide collateral security for all
but not part of the Debentures; or (f) to establish the form or terms of
Debentures of any other series as permitted by the Indenture; or (g) to provide
for the authentication and delivery of bearer securities and coupons
appertaining thereto representing interest, if any, thereon and for the
procedures for the registration, exchange and replacement thereof and for the
giving of notice to, and the solicitation of the vote or consent of, the Holders
thereof, and for any and all other matters incidental thereto; or (h) to
evidence and provide for the acceptance of appointment of a successor Debenture
Trustee under the Indenture with respect to the Debentures of one or more series
and to add to or change any of the provisions of the Indenture as shall be
necessary to provide for or to facilitate the administration of the trusts under
the Indenture by more than one trustee; or (i) to provide for the procedures
required to permit the utilization of a noncertificated system of registration
for the Debentures of all or any series; or (j) to change any place where (1)
the principal of and premium, if any, and interest, if any, on all or any series
of Debentures shall be payable, (2) all or any series of Debentures may be
surrendered for registration of transfer or exchange and (3) notices and demands
to or upon MidAmerican Energy in respect of Debentures and the Indenture may be
served; or (k) to cure any ambiguity or inconsistency or to add or change any
other provisions with respect to matters and questions arising under the
Indenture, provided such changes or additions shall not adversely affect the
interests of the Holders of Debentures of any series in any material respect.
(Section 1201).
 
    The Holders of at least a majority in aggregate principal amount of the
Debentures of all series then outstanding may waive compliance by MidAmerican
Energy with certain restrictive provisions of the Indenture. (Section 607). The
Holders of not less than a majority in principal amount of the outstanding
Debentures of any series may waive any past default under the Indenture with
respect to such series (and should the holders of such Debentures fail to waive
such default, the holders of a majority in aggregate liquidation preference of
the outstanding shares (if any) of the corresponding series of Preferred
Securities shall have such right), in each case except for a default in the
payment of principal, premium, or interest and certain covenants and provisions
of the Indenture that cannot be modified or be amended without the consent of
the Holder of each outstanding Debenture of such series affected. (Section 813).
 
    Without limiting the generality of the foregoing, if the Trust Indenture Act
is amended after the date of the Indenture in such a way as to require changes
to the Indenture or the incorporation therein of additional provisions or so as
to permit changes to, or the elimination of, provisions which, at the date of
the Indenture or at any time thereafter, were required by the Trust Indenture
Act to be contained in the
 
                                       26
<PAGE>
Indenture, the Indenture will be deemed to have been amended so as to conform to
such amendment of the Trust Indenture Act or to effect such changes, additions
or elimination, and MidAmerican Energy and the Debenture Trustee may, without
the consent of any Holders, enter into one or more supplemental indentures to
evidence or effect such amendment. (Section 1201).
 
    Except as provided above, the consent of the Holders of not less than a
majority in aggregate principal amount of the Debentures of all series then
outstanding, considered as one class, is required for the purpose of adding any
provisions to, or changing in any manner, or eliminating any of the provisions
of, the Indenture or modifying in any manner the rights of the Holders of such
Debentures under the Indenture pursuant to one or more supplemental indentures;
provided, however, that if less than all of the series of Debentures outstanding
thereunder are directly affected by a proposed supplemental indenture, then the
consent only of the Holders of a majority in aggregate principal amount of
outstanding Debentures of all series so directly affected, considered as one
class, will be required; and provided further, that no such amendment or
modification may (a) change the Stated Maturity of the principal of, or any
installment of principal of or interest on, any Debenture, or reduce the
principal amount thereof or the rate of interest thereon (or the amount of any
installment of interest thereon) or change the method of calculating such rate
or reduce any premium payable upon the redemption thereof, or change the coin or
currency or other property) in which any Debenture or any premium or the
interest thereon is payable, or impair the right to institute suit for the
enforcement of any such payment on or after the Maturity Date of any Debenture
(or, in the case of redemption, on or after the Redemption Date) without, in any
such case, the consent of the Holder of such Debenture, (b) reduce the
percentage in principal amount of the outstanding Debenture of any series, (or,
if applicable, in liquidation preference of Preferred Securities) the consent of
the Holders of which is required for any such supplemental indenture, or the
consent of the Holders of which is required for any waiver of compliance with
any provision of the Indenture or any default thereunder and its consequences,
or reduce the requirements for quorum or voting, without, in any such case, the
consent of the Holder of each outstanding Debenture of such series, or (c)
modify certain of the provisions of the Indenture relating to supplemental
indentures, waivers of certain covenants and waivers of past defaults with
respect to the Debenture of any series, without the consent of the Holder of
each outstanding Debenture affected thereby. A supplemental indenture which
changes or eliminates any covenant or other provision of the Indenture which has
expressly been included solely for the benefit of one or more particular series
of Debentures, or modifies the rights of the Holders of Debentures of such
series with respect to such covenant or other provision, will be deemed not to
affect the rights under the Indenture of the Holders of the Debentures of any
other series. (Section 1202).
 
    The Indenture provides that in determining whether the Holders of the
requisite principal amount of the outstanding Debentures have given any request,
demand, authorization, direction, notice, consent or waiver under the Indenture,
or whether a quorum is present at the meeting of the Holders of Debentures,
Debentures owned by MidAmerican Energy or any other obligor upon the Debentures
or any affiliate of MidAmerican Energy or of such other obligor (unless
MidAmerican Energy, such affiliate or such obligor owns all Debentures
outstanding under the Indenture, determined without regard to this provision)
shall be disregarded and deemed not to be outstanding. (Section 101).
 
    If MidAmerican Energy shall solicit from Holders any request, demand,
authorization, direction, notice, consent, election, waiver or other act,
MidAmerican Energy may, at its option, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other such act, but MidAmerican Energy
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 such record date, but only the Holders of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of the
outstanding Debentures have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other act, and
 
                                       27
<PAGE>
for that purpose the outstanding Debentures shall be computed as of the record
date. Any request, demand, authorization, direction, notice, consent, election,
waiver or other Act of a Holder shall bind every future Holder of the same
Debenture and the Holder of every Debenture issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Debenture Trustee or
MidAmerican Energy in reliance thereon, whether or not notation of such action
is made upon such Debenture. (Section 104).
 
RESIGNATION OF DEBENTURE TRUSTEE
 
    The Debenture Trustee may resign at any time by giving written notice
thereof to MidAmerican Energy or may be removed at any time by Act of the
Holders of a majority in principal amount of all series of Debentures then
outstanding delivered to the Debenture Trustee and MidAmerican Energy. No
resignation or removal of the Debenture Trustee and no appointment of a
successor trustee will become effective until the acceptance of appointment by a
successor trustee in accordance with the requirements of the Indenture. So long
as no Event of Default or event which, after notice or lapse of time, or both,
would become an Event of Default has occurred and is continuing and except with
respect to a Debenture Trustee appointed by Act of the Holders, if MidAmerican
Energy has delivered to the Debenture Trustee a resolution of its Board of
Directors appointing a successor trustee and such successor has accepted such
appointment in accordance with the terms of the Indenture, the Debenture Trustee
will be deemed to have resigned and the successor will be deemed to have been
appointed as trustee in accordance with the Indenture. (Section 910).
 
NOTICES
 
    Notices to Holders of Debentures will be given by mail to the addresses of
such Holders as they may appear in the security register therefor. (Section
106).
 
TITLE
 
    MidAmerican Energy, the Debenture Trustee, and any agent of MidAmerican
Energy or the Debenture Trustee, may treat the Person in whose name Debentures
are registered as the absolute owner thereof (whether or not such Debentures may
be overdue) for the purpose of making payments and for all other purposes
irrespective of notice to the contrary. (Section 308).
 
GOVERNING LAW
 
    The Indenture, the Supplemental Indentures and the Debentures will be
governed by, and construed in accordance with, the laws of the State of New
York. (Section 112).
 
CONCERNING THE DEBENTURE TRUSTEE
 
    The Debenture Trustee under the Indenture is The First National Bank of
Chicago. In addition, The First National Bank of Chicago acts as Property
Trustee under the Trust Agreements and as Guarantee Trustee under the Guarantee.
First Chicago Delaware Inc. acts as the Delaware Trustee under the Trust
Agreements. See "Description of the Preferred Securities -- Concerning the
Property Trustee."

<PAGE>
                        RELATIONSHIP AMONG THE PREFERRED
                 SECURITIES, THE DEBENTURES AND THE GUARANTEES
 
    As long as payments of interest and other payments are made when due on each
series of Debentures, such payments will be sufficient to cover Distributions
and other payments due on the Preferred Securities of the corresponding series,
because: (i) the aggregate principal amount of each series of Debentures will be
equal to the sum of the aggregate stated Liquidation Amount of the corresponding
Trust Securities; (ii) the interest rate and interest and other payment dates on
each series of Debentures will correspond to the Distribution rate and
Distribution and other payment dates on the Preferred Securities of such series;
(iii) the Expense Agreements entered into by MidAmerican Energy pursuant to the
Trust Agreements provide that MidAmerican Energy shall pay for all, and an
Issuer shall not be obligated to pay, directly or indirectly, for any, costs,
expenses or liabilities of such Issuer, including any income taxes, duties and
other governmental charges, and all costs and expenses with respect thereto, to
which such Issuer may become subject, except for United States withholding taxes
and such Issuer's payment obligations to holders of the Preferred Securities of
a particular series under such Preferred Securities; and (iv) each Trust
Agreement further provides that the Trustees shall not cause or permit an Issuer
to, among other things, engage in any activity that is not consistent with the
limited purposes of each Issuer.
 
    Payments of Distributions and other amounts due on Preferred Securities of
each series (to the extent an Issuer has funds sufficient for such payments) are
guaranteed by MidAmerican Energy as and to the extent set forth under
"Description of the Guarantees." The Debentures and the Guarantees, together
with the obligations of MidAmerican Energy with respect to the Preferred
Securities under the Indenture, the Trust Agreements, the Guarantees and the
Expense Agreements constitute full and unconditional guarantees of the Preferred
Securities by MidAmerican Energy. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such
guarantees. It is only the combined operation of these documents that has the
effect of providing full and unconditional guarantees by MidAmerican Energy of
the Preferred Securities. If and to the extent that MidAmerican Energy does not
make payments on any series of Debentures, such Issuer will not pay
Distributions or other amounts due on the Preferred Securities of the
corresponding series.
 
    Notwithstanding anything to the contrary in the Indenture, MidAmerican
Energy has the right to set-off any payment it is otherwise required to make
thereunder with and to the extent MidAmerican Energy has theretofore made, or is
concurrently on the date of such payment making, a payment under the related
Guarantee.
 
    If the Guarantee Trustee fails to enforce any Guarantee, a Holder of a
Preferred Security to which such Guarantee applies may institute a legal
proceeding directly against MidAmerican Energy to enforce such Holder's rights
under such Guarantee without first instituting a legal proceeding against the
Issuer of such Preferred Security or any other person or entity.
 
    Each Issuer's Preferred Securities will evidence the rights of the Holders
thereof to the benefits of such Issuer, a trust that exists for the sole purpose
of issuing its Trust Securities and investing the proceeds of its Preferred
Securities in corresponding series of Debentures of MidAmerican Energy while
each series of Debentures represents indebtedness of MidAmerican Energy. A
principal difference between the rights of a Holder of a Preferred Security and
a Holder of a Debenture is that a Holder of a Debenture will accrue, and
(subject to the permissible extensions of the interest payment period) is
entitled to receive, interest on the principal amount of Debentures held, while
a Holder of Preferred Securities is only entitled to receive Distributions if
and to the extent the Issuer has funds sufficient for the payment of such
Distributions.
 
    Upon any voluntary or involuntary dissolution, winding up or termination of
any Issuer involving the distribution of a series of Debentures, the Holders of
Trust Securities of the corresponding series will be
 
                                       29
<PAGE>
entitled to receive, out of assets legally available for distribution to such
Holders, a Liquidation Distribution; provided, however, that if an Event of
Default under an applicable Trust Agreement shall have occurred and be
continuing, the Holders of the Common Securities shall be entitled to receive,
out of assets legally available for Distribution to such Holders, distributions
only after the Holders of the corresponding Preferred Securities. See
"Description of the Preferred Securities -- Liquidation, Distribution Upon
Dissolution." Upon any voluntary or involuntary liquidation or bankruptcy of
MidAmerican Energy, each Issuer, as a Holder of Debentures, would be a
subordinated creditor of MidAmerican Energy, junior in right of payment to all
Senior Indebtedness, but entitled to receive payment in full of principal and
interest before any stockholders of MidAmerican Energy receive any payments or
distributions. Since MidAmerican Energy has agreed to pay for all costs,
expenses and liabilities of the Issuers (other than United States withholding
taxes and other than the Issuers' obligations to the Holders of Preferred
Securities under the Preferred Securities, which obligations are independently
covered by the Guarantees), the positions of a Holder of Preferred Securities
and a Holder of Debentures relative to other creditors and to stockholders of
MidAmerican Energy in the event of a liquidation or bankruptcy of MidAmerican
Energy would be substantially the same.
 
    A default or event of default under any Senior Indebtedness will not
constitute a default or Event of Default under the Debentures. However, in the
event of payment defaults under, or acceleration of, Senior Indebtedness, the
subordination provisions of the Debentures provide that no payments may be made
in respect of the Debentures until such Senior Indebtedness has been paid in
full or any payment default thereunder has been cured or waived.
 
    Failure to make required payments on any series of Debentures would
constitute an Event of Default under the Indenture.
 
                              PLAN OF DISTRIBUTION
 
    The Preferred Securities may be sold in a public offering to or through
underwriters or dealers designated from time to time. An Issuer may sell its
Preferred Securities as soon as practicable after the effectiveness of the
Registration Statement of which this Prospectus is a part. The names of any
underwriters or dealers involved in the sale of the Preferred Securities of a
particular series in respect of which this Prospectus is delivered, the number
of Preferred Securities to be purchased by any such underwriters or dealers and
the applicable commissions or discounts will be set forth in the applicable
Prospectus Supplement.
 
    Underwriters may offer and sell Preferred Securities at a fixed price or
prices, which may be changed, or from time to time at market prices prevailing
at the time of sale, at prices related to such prevailing market prices or at
negotiated prices. In connection with the sale of Preferred Securities,
underwriters will be deemed to have received compensation from MidAmerican
Energy and/or an Issuer in the form of underwriting discounts or commissions.
Underwriters may sell Preferred Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters.
 
    Any underwriting compensation paid by MidAmerican Energy to underwriters in
connection with the offering of the Preferred Securities, and any discounts,
concessions or commissions allowed by such underwriters to participating
dealers, will be set forth in the applicable Prospectus Supplement. Underwriters
and dealers participating in the distribution of Preferred Securities may be
deemed to be underwriters, and any discounts and commissions received by them,
and any profit realized by them on resale of such Preferred Securities, may be
deemed to constitute underwriting discounts and commissions under the Securities
Act. Underwriters and dealers may be entitled, pursuant to their agreement with
MidAmerican Energy and an Issuer, to indemnification against and contribution
toward certain civil liabilities, including liabilities under the Securities
Act, and to reimbursement by MidAmerican Energy for certain expenses.
 
                                       30
<PAGE>
    In connection with the offering of the Preferred Securities of a particular
series, the Issuer thereof may grant to the underwriters an option to purchase
additional Preferred Securities to cover over-allotments, if any, at the initial
public offering price (with an additional underwriting commission), as set forth
in the applicable Prospectus Supplement.
 
    Underwriters and dealers may engage in transactions with, or perform
services for, MidAmerican Energy, an Issuer and any of their respective
affiliates.
 
    An Issuer's Preferred Securities will be a new issue of securities and will
have no established trading market. Any underwriters to whom an Issuer's
Preferred Securities are sold by such Issuer for public offering and sale may
make a market in such Preferred Securities, but such underwriters will not be
obligated to do so and may discontinue any market-making at any time without
notice. Such Preferred Securities may or may not be listed on a national
securities exchange. No assurance can be given as to the liquidity of or the
existence of meaningful trading markets for any Preferred Securities.
 
                                 LEGAL MATTERS
 
    Certain legal matters will be passed upon for MidAmerican Energy by John A.
Rasmussen, Jr., Group Vice President and General Counsel of MidAmerican Energy,
and by Richards, Layton & Finger, special Delaware counsel to MidAmerican Energy
and the Issuers. The validity of the Preferred Securities will be passed upon
for the underwriters by Sidley & Austin. Sidley & Austin regularly serves as
special counsel to MidAmerican Energy and its affiliates on certain matters.
Sidley & Austin will rely upon the opinion of John A. Rasmussen, Jr., as to
matters of Iowa law. Mr. Rasmussen is an officer and full-time employee of
MidAmerican Energy and at September 30, 1996, he owned directly and/or
beneficially 6,200 shares of common stock of MidAmerican Energy and had been
granted, pursuant to and subject to the terms of MidAmerican Energy's Long-Term
Incentive Plan, options to purchase 40,000 shares of MidAmerican Energy common
stock and 6,500 performance shares.
 
                                    EXPERTS
 
    The consolidated financial statements and supporting schedules included in
or incorporated by reference in MidAmerican Energy's 1995 Annual Report on Form

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Sections 490.850-490.855 and 490.857 of the Iowa Business Corporation Act
("IBCA") permit corporations organized thereunder to indemnify directors,
officers, employees and agents against liability under certain circumstances.
The Restated Articles of Incorporation ("Articles of Incorporation") and the
Restated Bylaws ("Bylaws") of the Company provide for indemnification of
directors, officers and employees to the full extent provided by the IBCA. The
Articles of Incorporation and the Bylaws state that the indemnification provided
therein shall not be deemed exclusive. The Company may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Company or another corporation, partnership, joint venture, trust
or other enterprise against any expense, liability or loss, whether or not the
Company would have the power to indemnify such person against such expense,
liability or loss under the IBCA. Pursuant to Section 490.857 of the IBCA, the
Articles of Incorporation and the Bylaws, the Company maintains directors' and
officers' liability insurance coverage. The Company has also entered into
indemnification agreements with certain directors and officers, and expects to
enter into similar agreements with future directors and officers, to further
assure such persons indemnification as permitted by Iowa law.
 
    As permitted by Section 490.832 of the IBCA, the Articles of Incorporation
of the Company provide that no director shall be personally liable to the
Company or its shareholders for monetary damages for breach of fiduciary duty as
a director, except for liability: (i) for any breach of the directors's duty of
loyalty to the Company or its shareholders, (ii) for acts or omissions not in
good faith or which involve intentional midconduct or a knowing violation of
law, (iii) under Section 490.833 of the IBCA (relating to certain unlawful
distributions to shareholders) or (iv) for any transaction from which the
director derived an improper personal benefit.
 
    The forms of Underwriting Agreement and Distribution Agreement filed as
Exhibits 1(a) and 1(b) hereto include provisions requiring the underwriters,
dealers or agents to indemnify directors, officers and certain controlling
persons of the Company in certain circumstances.
 
    The Trust Agreements filed as Exhibits 4(c) and 4(d) hereto provide that
MidAmerican Energy shall indemnify each of the Issuer Trustees for, and to hold
each Issuer Trustee harmless against, any and all loss, damage, claims,
liability or expense incurred without negligence (gross negligence, in the case
of any Administrative Trustee), bad faith or willful misconduct on its part,
arising out of or in connection with the
 
                                      II-1
<PAGE>
acceptance or administration of the Trust Agreements, including the reasonable
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
thereunder.
 
ITEM 16. EXHIBITS.
 
    The Exhibits to this Registration Statement are listed in the Exhibit Index
on Page E-1 of this Registration Statement, which Index is incorporated herein
by reference.
 
ITEM 17. UNDERTAKINGS.
 
    The undersigned Registrants hereby undertake:
 
    1.  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement unless the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the Registration Statement:
 
        a.  To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;
 
        b.  To reflect in the prospectus any facts or events arising after the
    effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    Registration Statement. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total dollar value of
    securities offered would not exceed that which was registered) and any
    deviation from the low or high end of the estimated maximum offering range
    may be reflected in the form of prospectus filed with the Commission
    pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
    price represent no more than a 20 percent change in the maximum aggregate
    offering price set forth in the "Calculation of Registration Fee" table in
    the effective Registration Statement;
 
        c.  To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or any
    material change to such information in the Registration Statement;
 
    2.  That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    3.  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
MidAmerican Energy' s annual report pursuant to Section 13(a) or Section 15(d)
of the Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the provisions described under Item 15 above, or
otherwise, the Registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than
 
                                      II-2
<PAGE>
the payment by the Registrants of expenses incurred or paid by a director,
officer or controlling person of the Registrants in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrants will, unless in the opinion of their counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by them is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
    The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

To the Representative named in
Schedule I hereto of the Underwriters
named in Schedule II hereto.

Ladies and Gentlemen:

         MidAmerican Energy Financing I, a statutory business trust formed 
under the laws of the State of Delaware (the "Trust") and MidAmerican Energy 
Company, an Iowa corporation, as depositor of the Trust and as guarantor (the 
"Guarantor"), propose, subject to the terms and conditions stated herein, 
that the Trust issue and sell to the Underwriters named in Schedule II hereto 
(the "Underwriters"), an aggregate of $___________, __% Cumulative Quarterly 
Income Preferred Securities, Series A (liquidation amount $25 per preferred 
security) (the "Securities") representing beneficial interests in the Trust, 
guaranteed on a subordinated basis by the Guarantor as to the payment of 
distributions, and as to payments on liquidation or redemption, to the extent 
set forth in a guarantee agreement (the "Guarantee") between the Guarantor 
and The First National Bank of Chicago, a national banking corporation (the 
"Guarantee Trustee").  The Trust is to purchase, with the proceeds of the 
Securities and its Common Securities (liquidation amount $25 per common 
security) (the "Common Securities"), an aggregate of $___________, ___% 
Junior Subordinated Debentures, Series A due [  ](the "Subordinated 
Debentures") of the Guarantor, to be issued pursuant to an Indenture (the 
"Indenture") between the Guarantor and The First National Bank of Chicago, as 
trustee (the "Debenture Trustee"). The payments made by the Guarantor on the 
Subordinated Debentures are established at a level sufficient to permit the 
Trust, upon receipt of such payments, to make payments on the Securities in 
accordance with their tenor.

    lease and operate its properties and to conduct its business as described
    in the Prospectus; and the Guarantor is duly qualified as a foreign
    corporation to transact business and is in good standing in each
    jurisdiction in which such qualification is required, whether by reason of
    the ownership or leasing of property or the conduct of business, except
    where the failure so to qualify and be in good standing would not have a
    material adverse effect on the condition, financial or otherwise, or the
    earnings, business affairs or business prospects of the Guarantor.

         (b)  PUBLIC UTILITY.  The Guarantor has the legal right to function
    and operate as an electric public utility company in the States of Iowa,

    Securities") and certain other securities, has been prepared by the 
    Guarantor and the Trust in conformity with the requirements of the 1933 
    Act and the 1933 Act Regulations and has become effective.  As used in

    the SEC pursuant to Rule 424(a) of the 1933 Act Regulations; (iii) "Basic 
    Prospectus" means the prospectus (including all documents incorporated 
    therein by reference) specifically relating to the Registered Securities

    pursuant to paragraph (b) of Rule 424 of the 1933 Act Regulations.  The 
    SEC has not issued any order preventing or suspending the use of the 
    Prospectus.  The Guarantor meets the requirements for use of Form S-3 
    under the 1933 Act and the 1933 Act Regulations.

         (e)  REGISTRATION STATEMENT AND PROSPECTUS - ACCURACY.  The 
    Registration Statement and the Prospectus contain, and (in case of any

    Act of 1934, as amended ("1934 Act"),  and the rules and regulations of 
    the SEC under such Acts; and the Registration Statement and the 
    Prospectus do not, and (in the case of any amendment or supplement to any 
    such document, or any material incorporated by reference in any such 
    document, filed with the SEC after the date as of which this 
    representation is being made) will not, at any time during the period 
    specified in Section 3(e) hereof, contain any untrue statement of a 
    material fact or omit to state any material fact required to be stated 
    therein or necessary to make the statements therein not misleading; 
    PROVIDED, HOWEVER, that the representations and warranties in this 
    subsection shall not apply to statements in or omissions from the 
    Registration Statement or Prospectus made in reliance upon and in 
    conformity with information furnished to the Trust or the Guarantor in 
    writing by any Underwriter through the Representative expressly for use 
    in the Registration Statement or Prospectus.

    reference in any Preliminary Prospectus or the Prospectus, at the time 
    they were or hereafter are filed with the SEC, complied or when so filed

    requirements of the 1934 Act and the rules and regulations promulgated

          other similar laws relating to or affecting the enforcement of 
          creditors' rights generally, and general equitable principles;

              (viii)  the Subordinated Debentures are subordinate and junior in
         right of payment to all "Senior Indebtedness" (as defined in the
         Indenture) of the Company;

              (ix)  the Company's obligations under the Guarantees are

         by the Company;

              (x) the Trust Agreement, the Indenture and the Guarantee
         Agreement each have been duly qualified under the TIA;

such amendment became effective or at the time of the most recent such filing,

         (d)  OPINION OF SPECIAL DELAWARE COUNSEL.  Richards, Layton & Finger
special Delaware counsel, shall have furnished to the Representative a letter
addressed to the Underwriters and dated the Delivery Date to the effect that:

              (i)  The Trust has been duly created and is validly existing in
         good standing as a business trust under the Delaware Business Trust
         Act, and all filings required under the laws of the State of Delaware
         with 

                                   -18-

<PAGE>


         respect to the creation and valid existence of the Trust as a
         business trust have been made.

             (ii)  Under the Delaware Business Trust Act and the Trust
         Agreement, the Trust has the requisite trust power and authority to
         own property and conduct its business, all as described in the
         Prospectus.

            (iii)  The Trust Agreement constitutes a valid and binding
         obligation of the Guarantor and the Trustees and is enforceable
         against the Guarantor and the Trustees in accordance with its terms,
         subject as to enforceability to (a) bankruptcy, insolvency,
         moratorium, receivership, reorganization, liquidation, fraudulent
         conveyance and other similar laws relating to or affecting the rights
         and remedies of creditors generally, (b) principles of equity,
         including applicable law relating to fiduciary duties (regardless of
         whether considered and applied in a proceeding in equity or at law)
         and (c) the effect of applicable public policy on the enforceability
         of provisions relating to indemnification or contribution.

              (iv) Under the Business Trust Act and the Trust Agreement, the
         Trust has the requisite trust power and authority to (a) execute and
         deliver, and to perform its obligations under, the Underwriting
         Agreement and (b) issue and perform its obligations under the
         Securities.

               (v) Under the Business Trust Act and the Trust Agreement, the
         execution and delivery by the Trust of this Agreement, and the
         performance by the Trust of its obligations thereunder, have been duly
         authorized by the requisite trust action on the part of the Trust.

              (vi) The Securities have been duly authorized by the Trust
          Agreement and are duly and validly issued and, subject to the 
          qualifications set forth herein, fully paid and nonassessable
          beneficial interests in the Trust and are entitled to the benefits
          provided by the Trust Agreement. The Holders of the Securities, as
          beneficial owners of the Trust, will be entitled to the same
          limitation of personal liability extended to stockholders of
          private corporations for profit organized under the General
          Corporation Law of the State of Delaware.  Such counsel may note
          that the Securityholders may be obligated, pursuant to the Trust
          Agreement, to (a) provide indemnity or security in connection
          with and pay taxes or governmental charges arising from transfers
          or exchanges of certificates for the Securities certificates and the
          issuance of such certificates and (b) provide security or
          indemnity in connection with requests of or directions to the

                                   -19-

          Property Trustee to exercise its rights and remedies under the
          Trust Agreement.

             (vii) The Common Securities created under the Trust have been duly
         authorized by the Trust Agreement and are validly issued and represent
         beneficial interests in the Trust.

            (viii) Under the Business Trust Act and the Trust Agreement, the
         issuance of the Securities under the Trust is not subject to
         preemptive rights.

              (ix) The issuance and sale by the Trust of the securities created
         thereunder, the execution, delivery and performance by the Trust of
         this Agreement, the consummation by the Trust of the transactions
         contemplated thereby and compliance by the Trust with its obligations
         thereunder will not violate (a) any of the provisions of the
         Certificate of Trust of the Trust or the Trust Agreement or (b) any
         applicable Delaware law or administrative regulation.

               (x) No authorization, approval, consent or order of any Delaware
         court or governmental authority or agency is required to be obtained
         by the Trust solely in connection with the issuance and sale of the
         Securities created by the Trust.

              (xi) The Holders of the Securities (other than those Holders of
         the Securities who reside or are domiciled in the State of Delaware)
         will have no liability for income taxes imposed by the State of
         Delaware solely as a result of their participation in the Trust, and
         the Trust will not be liable for any income tax imposed by the State
         of Delaware.
         
         (e)  OFFICERS' CERTIFICATE.  Each of the Trust and the Guarantor shall
    have furnished to the Representative on the Delivery Date a certificate,
    dated the Delivery Date, of its Chairman of the Board, its President or a
    Vice President and its Treasurer or an Assistant Treasurer stating that, to
    the best of their knowledge after reasonable investigation, the
    representations and warranties of the Trust and the Guarantor as the case
    may be in Section 1 hereof are true and correct as of the Delivery Date;
    the Trust and the Guarantor have complied with all of their respective 
    agreements contained herein; and the conditions set forth in Sections 4(a),
    4(h), 4(i) and 4(j) hereof have been fulfilled;

         (f)  COMFORT LETTER.  On the Delivery Date, the Underwriters shall
    have received a letter from Arthur Andersen LLP dated as of the Delivery
    Date and in form and 

                                   -20-

<PAGE>

     substance satisfactory to the Representative, to the effect that:

              (i) They are independent public accountants with respect to the
         Trust and the Guarantor within the meaning of the 1933 Act and the
         1933 Act Regulations.

              (ii) In their opinion, the financial statements and supporting
         schedule(s) of the Guarantor audited by them and included or
         incorporated by reference in the Registration Statement comply as to
         form in all material respects with the applicable accounting
         requirements of the 1933 Act and the 1933 Act Regulations with respect
         to registration statements on Form S-3 and the 1934 Act and the 1934
         Act Regulations.

              (iii) They have performed specified procedures, not constituting
         an audit, including a reading of the latest available interim
         financial statements of the Guarantor, a reading of the minute books
         of the Guarantor since the end of the most recent fiscal year with
         respect to which an audit report has been issued, inquiries of and
         discussions with certain officials of the Guarantor responsible for
         financial and accounting matters with respect to the unaudited
         consolidated financial statements of the Guarantor included in the
         Registration Statement and Prospectus and the latest available interim
         unaudited financial statements of the Guarantor, and such other
         inquiries and procedures as may be specified in such letter, and on
         the basis of such inquiries and procedures nothing came to their
         attention that caused them to believe that:  (A) the unaudited
         consolidated financial statements of the Guarantor included in the
         Registration Statement and Prospectus do not comply as to form in all
         material respects with the applicable accounting requirements of the
         1934 Act and the 1934 Act Regulations or were not fairly presented in
         conformity with generally accepted accounting principles in the United
         States applied on a basis substantially consistent with that of the
         audited financial statements included therein, or (B) at a specified
         date not more than five days prior to the date of such letter, there
         was any change in the capital stock or any increase in long-term debt
         of the Guarantor or any decrease in the common shareholders' equity of
         the Guarantor other than for the declaration of regular quarterly
         dividends, in each case as compared with the amounts shown on the most
         recent balance sheet of the Guarantor included in the Registration
         Statement and Prospectus or, during the period from the date of such
         balance sheet to a specified date not more than five days prior to the
         date of such letter, there were any decreases, as compared with the
         corresponding period in the preceding 

                                   -21-

<PAGE>

          year, in operating revenues or net income of the Guarantor, except 
          in each such case as set forth in or contemplated by the 
          Registration Statement and Prospectus or except for such exceptions 
          (e.g. inability to determine such decreases because of insufficient 
          accounting information available after the date of such most recent 
          balance sheet) enumerated in such letter as shall have been agreed 
          to by the Representative and the Guarantor.

              (iv)  In addition to the examination referred to in their report
         included or incorporated by reference in the Registration Statement
         and the Prospectus, and the limited procedures referred to in clause
         (iii) above, they have carried out certain other specified procedures,
         not constituting an audit, with respect to certain amounts,
         percentages and financial information which are included or
         incorporated by reference in the Registration Statement and Prospectus
         and which are specified by the Representative, and have found such
         amounts, percentages and financial information to be in agreement with
         the relevant accounting, financial and other records of the Guarantor
         identified in such letter.

         (g)  ADDITIONAL COMFORT LETTER.  On the Delivery Date, the
    Underwriters shall have received a letter from Deloitte & Touche LLP dated
    as of the Delivery Date and in form and substance satisfactory to the
    Representative, to the effect of Section 4(f)(i) and (ii).

         (h)  OPINION OF UNDERWRITERS COUNSEL.  Sidley & Austin, as counsel for
    the Underwriters, shall have furnished to the Representative on the
    Delivery Date such opinions with respect to the validity of the Securities
    and with respect to the Registration Statement, the Prospectus, and other
    related matters as the Representative may reasonably require and including
    that:

              (i)  under current law, for United States federal income tax
         purposes (A) the Subordinated Debentures will constitute indebtedness
         of the Company and (B) the interest on the Subordinated Debentures
         will be deductible by the Company on an economic accrual basis in
         accordance with section 163(e) of the Internal Revenue Code of 1986,
         as amended, and Treasury Regulation Section 1.163-7, subject to any
         applicable limitations on the Company's ability to deduct interest on
         any of its indebtedness;

              (ii)  under current law, the Trust will be classified for United
         States federal income tax purposes as a grantor trust and not as an
         association taxable as a corporation; accordingly, for United

                                   -22-

<PAGE>


         States federal income tax purposes, each holder of Securities
         generally will be considered the owner of an undivided interest in
         the Subordinated Debentures, and each holder will be required to
         include in its gross income any original issue discount accrued with
         respect to its allocable share of the Subordinated Debentures;

              (iii)  the discussion set forth in the Prospectus Supplement
         under the caption "United States Federal Income Taxation" is a fair
         and accurate summary of the matters addressed therein, based upon
         current law and the assumptions stated or referred to therein; and

              (iv)  the Trust is not an "investment company" or an entity
         "controlled" by an "investment company" required to be registered
         under the 1940 Act;

         (i)  FERC AND ICC ORDERS.  The orders of the FERC and the ICC referred
    to in Sections 1(p)and 1(q) hereof shall be in full force and effect and no
    proceedings to suspend the effectiveness of either such order shall be
    pending or threatened;

         (j)  RATINGS.  Subsequent to the execution of this Agreement, there
    shall not have been any decrease in the ratings of the Securities or of 
    any of the equity securities of the Guarantor by either Standard & Poor's
    Rating Group or Moody's Investors Service Inc.; 

         (k)  NO MATERIAL ADVERSE CHANGE.  Subsequent to the date of the most
    recent financial statements incorporated by reference in the Prospectus,
    there shall have been no material adverse change in the condition
    (financial or otherwise), business or results of operations of the
    Guarantor, except as set forth in the Registration Statement and the
    Prospectus, including the documents incorporated by reference therein, as
    of the effective date of this Agreement, and 

         (l)  STOCK EXCHANGE LISTING.  The Securities to be sold by the Trust
    shall have been duly listed, subject to notice of issuance, on the New York
    Stock Exchange.

All opinions, letters, evidence, and certificates mentioned above or elsewhere
in this Agreement shall be deemed to be in compliance with the provisions hereof
only if they are in form and substance reasonably satisfactory to the
Representative.

    In case any of the conditions specified above in this Section 4 shall not
have been fulfilled on the Delivery Date, this Agreement may be terminated by
the Representative by delivering written notice of termination to the Trust and
the Guarantor.  Any such termination shall be without liability of

any party to any other party except to the extent provided in Sections 3, 7

    proceedings to suspend the effectiveness of either such order shall be
    pending or threatened; and

         (c)  OPINION OF COUNSEL.  The opinion of Sidley & Austin referred to

any other party except to the extent provided in Sections 3, 7 and 9 hereof.

    Section 6.  TERMINATION BY REPRESENTATIVE.  The Representative may
terminate this Agreement, immediately upon notice to the Trust or the Guarantor,
at any time prior to the Delivery Date (i) if there has been, since the date of

financial or otherwise, or in the earnings, business affairs or business
prospects of the Guarantor, whether or not arising in the ordinary course of
business, or (ii) if there shall have occurred any material adverse change in
the financial markets in the United States or any outbreak or escalation of
hostilities or other national or international calamity or crisis the effect of
which is such as to make it, in the judgment of the Representative,
impracticable to market the Securities or (iii) if trading in any securities of

Securities or to any equity security of the Guarantor as of the date of this

agency shall have publicly announced that it has under surveillance or 
review, with possible negative implications, any such rating or (v) if there 
shall have come to the attention of the Representative any facts that would 
cause the Representative to believe that the Prospectus, at the Delivery 
Date, contained an untrue statement of a material fact or omitted to state a 
material fact necessary in order to make the statements therein, in light of 
the circumstances existing at the time of such delivery, not misleading.

    Section 7.  PAYMENT OF EXPENSES IN CERTAIN CIRCUMSTANCES.  If the purchase
of the Securities by the Underwriters is not consummated for any reason other
than a default by one or more of the Underwriters, the Guarantor shall remain
responsible for the expenses to be paid or reimbursed by it pursuant to Section
3 hereof, the respective obligations of the Trust and the Guarantor and the
Underwriters pursuant to Section 9 hereof shall remain in effect, and the
Guarantor will reimburse the Representative for the reasonable out-of-pocket
expenses of the Underwriters, not exceeding $10,000, and for the fee and
disbursements of Sidley & Austin, the Underwriters agreeing to pay such
expenses, fee and disbursements in any other event.  In no event will the Trust
or the Guarantor be liable to any of the Underwriters for damages on account of
loss of anticipated profits.

    Section 8.  DEFAULT BY UNDERWRITERS.  If one or more of the Underwriters
shall fail at the Delivery Date to purchase the Securities which it or they are
obligated to purchase under this Agreement ("Defaulted Securities"), the
Representative shall have the right, within 24 hours thereafter, to make
arrangements for one or more of the non-defaulting Underwriters, or any other
underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Representative shall not have completed such
arrangements within such 24-hour period, then:

         (a)  if the amount of Defaulted Securities does not exceed 10% of the
    amount of the Securities, each of the non-defaulting Underwriters shall be
    obligated, severally and not jointly, to purchase the full amount thereof
    in the proportions that their respective underwriting obligations

                                   -25-

<PAGE>

    hereunder bear to the underwriting obligations of all non-defaulting
    Underwriters, or 

         (b)  if the amount of Defaulted Securities exceeds 10% of the amount
    of the Securities, this Agreement shall terminate without liability on the
    part of any non-defaulting Underwriter.

         No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a
termination of this Agreement, either the Representative or the Guarantor shall
have the right to postpone the Delivery Date for a period not exceeding seven
days in order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements.

    Section 9.  INDEMNIFICATION.  (a) INDEMNIFICATION OF THE UNDERWRITERS.  The
Trust and the Guarantor agree, jointly and severally, to indemnify and hold
harmless each Underwriter and each person, if any, who controls such Underwriter
within the meaning of Section 15 of the 1933 Act as follows:

              (i)  against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement
         or alleged untrue statement of a material fact contained in the
         Registration Statement (or any amendment thereto), or the omission or
         alleged omission therefrom of a material fact necessary to make the
         statements therein not misleading or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Prospectus (or any amendment or supplement thereto) or the
         omission or alleged omission therefrom of a material fact necessary to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading; 

              (ii)  against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or investigation or proceeding
         by any governmental agency or body, commenced or threatened, or any
         claim whatsoever based upon any such untrue statement or omission, or
         any such alleged untrue statement or omission, if such settlement is
         effected with the written consent of the Guarantor; and

              (iii) against any and all expense whatsoever, as incurred,
         (including, subject to Section 9(c) hereof, the fees and disbursements
         of counsel) reasonably incurred in investigating, preparing or
         defending

                                   -26-

<PAGE>


         against any litigation, or investigation or proceeding by any 
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under (i) or (ii) above.

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Trust or the
Guarantor by any Underwriter through the Representative expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto); and PROVIDED,
FURTHER, that this indemnity agreement with respect to any preliminary
prospectus shall not inure to the benefit of any Underwriter from whom the
person asserting any such losses, liabilities, claims, damages or expenses
purchased Securities, or any person controlling such Underwriter, if a copy of
the Prospectus (as then amended or supplemented if the Trust and the Guarantor
shall have furnished any such amendment or supplement thereto, but excluding
documents incorporated or deemed to be incorporated by reference therein) was
not sent or given by or on behalf of such Underwriter to such person, if such is
required by law, at or prior to the written confirmation of the sale of such
Securities to such person and if the Prospectus (as so amended or supplemented,
but excluding documents incorporated or deemed to be incorporated by reference
therein) would have corrected the defect giving rise to such loss, liability,
claim, damage or expense, it being understood that this proviso shall have no
application if such defect shall have been corrected in a document which is
incorporated or deemed to be incorporated by reference in the Prospectus.

         (b)  INDEMNIFICATION OF THE TRUST AND THE GUARANTOR.  Each Underwriter
    severally agrees to indemnify and hold harmless the Trust and the
    Guarantor, their respective trustees and directors, each of their
    respective  officers who signed the Registration Statement, and each
    person, if any, who controls the Trust or the Guarantor within the meaning
    of Section 15 of the 1933 Act against any and all loss, liability, claim,
    damage and expense described in the indemnity contained in subsection (a)
    of this Section, as incurred, but only with respect to untrue statements or
    omissions, or alleged untrue statements or omissions, made in the
    Registration Statement (or any amendment thereto) or any preliminary
    prospectus or the Prospectus (or any amendment or supplement thereto) in
    reliance upon and in conformity with written information furnished to the
    Trust and the Guarantor by such Underwriter through the Representative
    expressly for use in the Registration Statement (or any amendment thereto)
    or such preliminary

                                   -27-

<PAGE>


    prospectus or the Prospectus (or any amendment or supplement thereto).

         (c)  GENERAL.  Each indemnified party shall give prompt notice to each
    indemnifying party of any action commenced against it in respect of which
    indemnity may be sought hereunder, but failure so to notify an indemnifying
    party shall not relieve such indemnifying party from any liability which it
    may have otherwise than on account of this indemnity agreement.  An
    indemnifying party may participate at its own expense in the defense of
    such action.  In no event shall the indemnifying parties be liable for the
    fees and expenses of more than one counsel (in addition to any local
    counsel) for all indemnified parties in connection with any one action or
    separate but similar or related actions in the same jurisdiction arising
    out of the same general allegations or circumstances.

         (d)  CONTRIBUTION.  In order to provide for just and equitable
    contribution in circumstances in which the indemnity agreements provided
    for in this Section 9 are for any reason held to be unenforceable by the
    indemnified parties although applicable in accordance with their terms, the
    Trust and the Guarantor and the Underwriters shall contribute to the
    aggregate losses, liabilities, claims, damages and expenses of the nature
    contemplated by said indemnity agreements incurred by the Trust and the
    Guarantor and one or more of the Underwriters, as incurred, in such
    proportions that the Underwriters are responsible for that portion
    represented by the percentage that the commission to the Underwriters set
    forth under "Underwriting" in the Prospectus Supplement bears to the sum of
    (a) the initial public offering price appearing thereon and (b) such
    commission, and the Trust and the Guarantor, jointly and severally, are
    responsible for the balance; PROVIDED, HOWEVER, that no person guilty of
    fraudulent misrepresentation (within the meaning of Section 11(f) of the
    1933 Act) shall be entitled to contribution from any person who was not
    guilty of such fraudulent misrepresentation.  For purposes of this Section,
    each person, if any, who controls an Underwriter within the meaning of
    Section 15 of the 1933 Act shall have the same rights to contribution as
    such Underwriter, and each trustee of the Trust, each director of the Trust
    and the Guarantor, each officer of the Trust and the Guarantor who signed
    the Registration Statement, and each person, if any, who controls the
    Guarantor within the meaning of Section 15 of 1933 Act, shall have the same
    rights to contribution as the Guarantor.

    Section 10.  NOTICES.  The Trust and the Guarantor shall be entitled to act
and rely upon any request, consent, notice of agreement by, or on behalf of, the
Representative.  Any notice by the Trust or the Guarantor to the Underwriters
shall be 

                                   -28-

<PAGE>


sufficient if given in writing or by telegraph addressed to the 
Representative at its address set forth in Schedule I hereto, and any notice 
by the Underwriter to the Trust or the Guarantor shall be sufficient if given 
in writing or by telegraph addressed to the Guarantor, 666 Grand Avenue, Des 
Moines, Iowa  50309, Attention of the Treasurer.

    Section 11.  SUCCESSORS.  This Agreement shall be binding upon the
Underwriters, the Trust, the Guarantor and their respective successors.  This
Agreement and the terms and provisions hereof are for the sole benefit of only
those persons, except that (a) the representations, warranties, indemnities and
agreements of the Trust and the Guarantor contained in this Agreement shall also
be deemed to be for the benefit of the person or persons, if any, who control
any Underwriter within the meaning of Section 15 of the 1933 Act, and (b) the
indemnity agreement of the Underwriters contained in Section 9 hereof shall be
deemed to be for the benefit of directors of the Guarantor, the trustees and
officers of the Trust and the Guarantor who have signed the Registration
Statement and any person controlling the Trust or the  Guarantor.  Nothing in
this Agreement is intended or shall be construed to give any person, other than
the persons referred to in this Section 11, any legal or equitable right, remedy
or claim under or in respect of this Agreement or any provision contained
herein.  The term "successors" shall not include any purchaser of the Securities
merely because of such purchase.

    Section 12.  GOVERNING LAW.  The validity and interpretation of this
Agreement shall be governed by the laws of the State of New York.

    Section 13.  EXECUTION IN COUNTERPARTS.  This Agreement may be executed in
counterparts, each of which shall be an original and all of which shall
constitute but one and the same instrument.

[Name and Address of Agent(s)



Dear Sirs:

         MidAmerican Energy Company, an Iowa corporation (the "Company"), 
confirms its agreement with _________________ (the "Agent") with respect to 
the issue and sale by the Company of its Medium-Term Notes described herein 
(the "Notes").  The Notes are to be issued pursuant to an indenture (the 
"Indenture") dated as of _______ __, 1996 between the Company and The First 
National Bank of Chicago, as trustee (the "Trustee").  As of the date hereof, 
the Company has authorized the issuance and sale of up to $___,000,000 
aggregate principal amount of Notes through the Agent pursuant to the terms 
of this Agreement.  It is understood, however, that the Company from time to 
time may reduce the maximum principal amount of Notes which it may issue and 
sell or authorize the issuance of additional Notes and that such additional 
Notes may be sold through or to the Agent pursuant to the terms of this 
Agreement, all as though the issuance of such Notes were authorized as of the 
date hereof.

    This Agreement provides both for the sale of Notes by the Company 
directly to purchasers, in which case the Agent will act as agent of the 
Company in soliciting Note purchases, and (as may from time to time be agreed 
to by the Company and the Agent) to the Agent as principal for resale to 
purchasers.


<PAGE>

    The Company has filed with the Securities and Exchange Commission (the 
"SEC") a registration statement on Form S-3 (No. 333-_____) for the 
registration of certain securities, including the Notes, under the Securities 
Act of 1933 (the "1933 Act") and the offering thereof from time to time in 
accordance with Rule 415 of the rules and regulations of the SEC under the 
1933 Act (the "1933 Act Regulations").  Such registration statement has been 
declared effective by the SEC and the Indenture has been qualified under the 
Trust Indenture Act of 1939, as amended (the "1939 Act").  Such registration 
statement (and any further registration statements which may be filed by the 
Company for the purpose of registering additional Notes and in connection 
with which this Agreement is included or incorporated by reference as an 
exhibit) and the prospectus specifically relating to the Notes constituting a 
part thereof, and any prospectus supplements specifically relating to the 
Notes, including all documents incorporated therein by reference, as from 
time to time amended or supplemented by the filing of documents pursuant to 
the Securities Exchange Act of 1934 (the "1934 Act") or the 1933 Act or 
otherwise, are referred to herein as the "Registration Statement" and the 
"Prospectus", respectively, except that if any revised prospectus 
specifically relating to the Notes shall be provided to the Agent by the 
Company for use in connection with the offering of the Notes which is not 
required to be filed by the Company pursuant to Rule 424(b) of the 1933 Act 
Regulations, the term "Prospectus" shall refer to such revised prospectus 
from and after the time it is first provided to an agent for such use.

SECTION 1.    APPOINTMENT AS AGENT.

    (a)  APPOINTMENT OF AGENT.  Subject to the terms and conditions stated 
herein and subject to the reservation by the Company of the right to sell 
Notes directly on its own behalf, the Company hereby appoints the Agent as 
its agent for the purpose of soliciting purchases of the Notes from the 
Company by others and agrees that, except as otherwise contemplated herein, 
whenever the Company determines to sell Notes directly to the Agent as 
principal for resale to others, it will enter into a Terms Agreement 
(hereafter defined) relating to such sale in accordance with the provisions 
of Section 3(b) hereof.  The Agent is authorized to appoint sub-agents or to 
engage the services of any other broker or dealer in connection with the 
offer or sale of the Notes.  The Company agrees that, during the period the 
Agent is acting as the Company's Agent hereunder, the Company will not 
contact or solicit potential investors introduced to it by the Agent to 
purchase the Notes.  The Company may appoint, upon one day prior written 
notice to the Agent, additional persons to serve as Agent hereunder, but 


                                    2

<PAGE>

only if each such additional person agrees to be bound by all of the terms of 
this Agreement as an agent.

    (b)  REASONABLE EFFORTS SOLICITATIONS; RIGHT TO REJECT OFFERS.  Upon 
receipt of instructions from the Company, the Agent will use its reasonable 
efforts to solicit purchases of such principal amount of the Notes as the 
Company and the Agent shall agree upon from time to time during the term of 
this Agreement, it being understood that the Company shall not approve the 
solicitation of purchases of Notes in excess of the amount which shall be 
authorized by the Company from time to time or in excess of the principal 
amount of Notes registered pursuant to the Registration Statement.  The Agent 
will have no responsibility for maintaining records with respect to the 
aggregate principal amount of Notes sold, or of otherwise monitoring the 
availability of Notes for sale under the Registration Statement.  The Agent 
will communicate to the Company, orally or in writing, each offer to purchase 
Notes, other than those offers rejected by the Agent.  The Agent shall have 
the right, in its discretion reasonably exercised, to reject any proposed 
purchase of Notes, as a whole or in part, and any such rejection shall not be 
deemed a breach of the Agent's agreement contained herein.  The Company may 
accept or reject any proposed purchase of the Notes, in whole or in part.

    (c)  SOLICITATIONS AS AGENT; PURCHASES AS PRINCIPAL.  In soliciting 
purchases of the Notes on behalf of the Company, the Agent shall act solely 
as agent for the Company and not as principal.  The Agent shall make 
reasonable efforts to assist the Company in obtaining performance by each 
purchaser whose offer to purchase Notes has been solicited by the Agent and 
accepted by the Company.  The  Agent shall not have any liability to the 
Company in the event any such purchase is not consummated for any reason.  
The Agent shall not have any obligation to purchase Notes from the Company as 
principal, but the Agent may agree from time to time to purchase Notes as 
principal.  Any such purchase of Notes by the Agent as principal shall be 
made pursuant to a Terms Agreement in accordance with Section 3(b) hereof.

    (d)  RELIANCE.  The Company and the Agent agree that any Notes the 
placement of which the Agent arranges shall be placed by the Agent, and any 
Notes purchased by the Agent shall be purchased, in reliance on the 
representations, warranties, covenants and agreements of the Company 
contained herein and on the terms and conditions and in the manner provided 
herein.


                                    3

SECTION 2.    REPRESENTATIONS AND WARRANTIES.

    (a)  The Company represents and warrants to the Agent as of the date 
hereof, as of the date of each acceptance by the Company of an offer for the 
purchase of Notes (whether through the Agent as agent or to the Agent as 
principal), as of the date of each delivery of Notes (whether through the 
Agent as agent or to the Agent as principal) (the date of each such delivery 
to the Agent as principal being hereafter referred to as a "Settlement 
Date"), and as of any time that the Registration Statement or the Prospectus 
shall be amended or supplemented (other than by an amendment or supplement 
providing solely for a change in the interest rates of Notes or similar 
changes) or there is filed with the SEC any document incorporated by 
reference into the Prospectus (other than any Current Report on Form 8-K 
relating exclusively to the issuance of debt securities under the 
Registration Statement, unless the Agent shall otherwise specify) (each of 
the times referenced above being referred to herein as a "Representation 
Date") as follows:

         (i)  DUE INCORPORATION AND QUALIFICATION.  The Company has been duly 
    incorporated and is validly existing as a corporation in good standing 
    under the laws of the state of Iowa with corporate power and authority to 
    own, lease and operate its properties and to conduct its business as 
    described in the Prospectus; and the Company is duly qualified as a 
    foreign corporation to transact business and is in good standing in each 
    jurisdiction in which such qualification is required, whether by reason 
    of the ownership or leasing of property or the conduct of business, 
    except where the failure to so qualify and be in good standing would not 
    have a material adverse effect on the condition, financial or otherwise, 
    or the earnings, business affairs or business prospects of the Company.

        (ii)  PUBLIC UTILITY.  The Company has the legal right to  function  
    and operate as an electric public utility company in the States of Iowa, 
    Illinois and South Dakota, and as a gas public utility company in the 
    States of Iowa, Illinois, South Dakota and Nebraska.

 
       (iii)  SUBSIDIARIES.  The Company has no significant subsidiaries, as 
    "significant subsidiary" is defined in Rule 405 of Regulation C of the 
    rules and regulations ("1933 Act Regulations") promulgated by the 
    Securities and Exchange Commission ("SEC") under the Securities Act of 
    1933, as amended ("1933 Act").

<PAGE>

        (iv) REGISTRATION STATEMENT AND PROSPECTUS.  At the time the 
    Registration Statement became effective, the Registration Statement 
    complied, and as of the applicable Representation Date will comply, in 
    all material respects, with the requirements of the 1933 Act and the 1933 
    Act Regulations and the 1939 Act and the rules and regulations of the SEC 
    promulgated thereunder.  The Registration Statement, at the time it 
    became effective, did not, and at each time thereafter at which any 
    amendment to the Registration Statement becomes effective or any Annual 
    Report on Form 10-K is filed by the Company with the SEC and as of each 
    Representation Date, will not, contain an untrue statement of a material 
    fact or omit to state a material fact required to be stated therein or 
    necessary to make the statements therein not misleading.  The Prospectus, 
    as of the date hereof does not, and as of each Representation Date will 
    not, contain an untrue statement of a material fact or omit to state a 
    material fact necessary in order to make the statements therein, in the 
    light of the circumstances under which they were made, not misleading; 
    PROVIDED, HOWEVER, that the representations and warranties in this 
    subsection shall not apply to statements in or omissions from the 
    Registration Statement or Prospectus made in reliance upon and in 
    conformity with information furnished to the Company in writing by the 
    Agent expressly for use in the Registration Statement or Prospectus.

        (v) INCORPORATED DOCUMENTS.  The documents incorporated by reference 
    in any Preliminary Prospectus or the Prospectus, at the time they were or 
    hereafter are filed with the SEC, complied or when so filed will comply, 
    as the case may be, in all material respects with the requirements of the 
    1934 Act and the rules and regulations promulgated thereunder ("1934 Act 
    Regulations"), and, when read together with the other information in the 
    Prospectus, did not and will at all times during the period specified in 
    Section 4(e) hereof not contain an untrue statement of a material fact or 
    omit to state a material fact required to be stated therein or necessary 
    in order to make the statements therein, in the light of the 
    circumstances under which they were or are made, not misleading.

    The Company agrees to pay the Agent a commission, in the form of a 
discount, equal to the applicable percentage of the principal amount of each 
Note sold by the Company as a result of a solicitation made by such Agent as 
set forth in Schedule A hereto.  The Agent may allow any portion of the 
commission payable pursuant hereto to dealers or purchasers in connection 
with the offer and sale of any Notes.

    The purchase price, interest rate, maturity date and other terms of the 
Notes shall be agreed upon by the Company and the Agent and set forth in a 
pricing supplement to the Prospectus to be prepared following each acceptance 
by the Company of an offer for the purchase of Notes.  Except as may be 
otherwise provided in such supplement to the Prospectus, the Notes will be 
issued in denominations of $100,000 or any larger amount that is an integral 
multiple of $1,000.  All Notes sold through the Agent as agent will be sold 
at 100% of their principal amount unless otherwise agreed to by the Company 
and the Agent.

    (b)  PURCHASES AS PRINCIPAL.  Each sale of Notes to the Agent as 
principal shall be made in accordance with the terms contained herein and

include any applicable Terms Agreement between the Company and the Agent.  
Each such Terms Agreement, whether oral or in writing, shall be with respect

Agent's commitment to purchase Notes as principal pursuant to any Terms 
Agreement or otherwise shall be deemed to have been made on the basis of the 
representations and warranties of the Company herein contained and shall be 
subject to the terms and conditions herein set forth.  Each Terms Agreement 
shall specify the principal amount of Notes to be purchased by the Agent 
pursuant thereto, the price to be paid to the Company for such Notes (which, 
if not so specified in a Terms Agreement, shall be at a discount equivalent 
to the applicable commission set forth in Schedule A hereto), the time and 
place of delivery of and payment for such Notes, any provisions relating to 
rights of, and default by purchasers acting together with the Agent in the

    the Prospectus;

         (vi) the Indenture is qualified under the 1939 Act;

         (vii) the orders of the FERC and the ICC referred to in Section 
    2(a)(xi) hereof pertaining to the Notes have been duly entered and, to 
    the best of the knowledge of such counsel, are still in force and effect; 
    and no further approval, authorization, consent, certificate or order of 
    any state or federal commission or regulatory authority (other than in 
    connection or compliance with the provisions of the securities or Blue 
    Sky laws of any jurisdiction) is necessary with respect to the issue and 
    sale of the Notes as contemplated by this Agreement;

                                      17

         (viii) the Registration Statement has become effective under the 
    1933 Act and, to the best of the knowledge of such counsel, no stop order

    issued and no proceedings for that purpose have been instituted or are 
    pending or threatened under the 1933 Act;

         (ix) the Registration Statement and the Prospectus and each 
    amendment or supplement thereto comply as to form in all material

         (x) such counsel does not know of any legal or governmental 
    proceeding required to be described in the Prospectus which is not 
    described as required, or of any contract or document of a character 
    required to be described or incorporated in the Registration Statement or 
    the Prospectus or to be filed as an exhibit to the Registration Statement 
    which is not described, incorporated or filed as required;

         (xi) neither the execution and delivery of this Agreement and the 
    Indenture nor the issuance and sale of the Notes in accordance with the 
    terms of this Agreement or Terms Agreement nor the consummation of the 
    transactions therein contemplated, nor compliance with the terms and 
    provisions thereof, will conflict with, violate or result in a breach of 
    any law, any administrative regulation or any court decree known to such 
    counsel to be applicable to the Company, conflict with or result in a 
    breach of any of the terms, conditions or provisions of the Articles of 
    Incorporation or the by-laws of the Company or of any material agreement 
    or instrument known to such counsel to which the Company is a party or by

    in the creation or imposition of any lien, charge or encombrance of any 
    nature whatsoever upon any of the properties or assets of the Company;

         (xii) the documents referred to in Section 2(a)(v) hereof, as of 
    their respective filing dates, complied as to form in all material

                                      18

<PAGE>

         (xiii) the statements made in the Prospectus which are stated 
    therein to have been made on the authority of such counsel have been 
    reviewed by him and, as to matters of law and legal conclusion, are 
    correct;

         (xiv) the Company is a public utility authorized by its Articles of 
    Incorporation to carry on the businesses in which it is engaged, as set 
    forth in the Prospectus; the Company has the legal right to function and 
    operate as an electric public utility company in the States of Iowa, 
    Illinois and South Dakota, and as a gas public utility company in the 
    States of Iowa, Illinois, South Dakota and Nebraska; and the franchises 
    and permits of the Company are valid and subsisting and authorize the 
    Company to carry on the utility businesses in which it is engaged in the 
    communities and territory covered by such franchises and permits;

         (xv) the descriptions in the Registration Statement and the 
    Prospectus of statutes, legal and governmental proceedings and contracts 
    and other documents are accurate and fairly present the information 
    required to be presented; and 

         (xvi) except as set forth in the Prospectus, (A) there are no 
    pending legal proceedings to which the Company is a party or in which any 
    of its property is the subject which are material to the Company, other 
    than ordinary routine legal proceedings incident to the business in which 
    the Company is engaged, and (B) there are no material pending 
    administrative or judicial proceedings to which the Company is a party or 
    in which any of its property is the subject arising under any federal, 
    state or local provisions regulating the discharge of materials into the 
    environment or otherwise relating to the protection of the environment, 
    and, to the best of the knowledge of said counsel, no such proceedings 
    are threatened by governmental authorities;

and such letter shall additionally state that nothing has come to the 
attention of such counsel that would lead him to believe that the 
Registration Statement, at the time it became effective, and if an amendment 
to the Registration Statement or an Annual Report on Form 10-K has been filed 
by the Company with the SEC subsequent to the effectiveness of the 
Registration Statement, then at the time such amendment became effective or 
at the time of the most recent such filing, and at the date hereof, or (if 
such opinion is being delivered in connection with a Terms Agreement pursuant 
to Section 3(b) hereof) at the date of any Terms Agreement and at the 
Settlement Date with respect thereto as the case may be, contains 

                                      19
<PAGE>

or contained an untrue statement of a material fact or omitted to state a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading or that the Prospectus as amended or 
supplemented at the date hereof, or (if such opinion is being delivered in 
connection with a Terms Agreement pursuant to Section 3(b) hereof) at the 
date of any Terms Agreement and at the Settlement Date with respect thereto, 
as the case may be, contains or contained any untrue statement of a material 
fact or omitted or omits to state a material fact necessary in order to make 
the statements therein, in the light of the circumstances under which they 
were made, not misleading.

         (d)  OFFICERS' CERTIFICATE.  The Company shall have furnished to the
    Agent on the date hereof a certificate, dated the date hereof, of its
    Chairman of the Board, its President or a Vice President and its Treasurer
    or an Assistant Treasurer stating that, to the best of their knowledge
    after reasonable investigation, the representations and warranties of the
    Company in Section 2 hereof are true and correct as of the date hereof; the
    Company has complied with all its agreements contained herein; and the
    conditions set forth in Sections 5(a), 5(g), 5(h)and 5(i) hereof have been
    fulfilled;

         (e)  COMFORT LETTER.  On the date hereof, the Agent shall have
    received a letter from Arthur Andersen LLP. dated as of the date hereof and
    in form and substance satisfactory to the Representative, to the effect
    that:

              (i) They are independent public accountants with respect to the
         Company within the meaning of the 1933 Act and the 1933 Act
         Regulations.

              (ii) In their opinion, the financial statements and supporting
         schedule(s) of the Company audited by them and included or
         incorporated by reference in the Registration Statement comply as to
         form in all material respects with the applicable accounting
         requirements of the 1933 Act and the 1933 Act Regulations with respect
         to registration statements on Form S-3 and the 1934 Act and the 1934
         Act Regulations.

              (iii) They have performed specified procedures, not constituting
         an audit, including a reading of the latest available interim
         financial statements of the Company, a reading of the minute books of
         the Company since the end of the most recent fiscal year with respect
         to which an audit report has been issued, inquiries of and 


                                     20

<PAGE>


          discussions with certain officials of the Company responsible for 
          financial and accounting matters with respect to the unaudited 
          consolidated financial statements of the Company included in the 
          Registration Statement and Prospectus and the latest available 
          interim unaudited financial statements of the Company, and such 
          other inquiries and procedures as may be specified in such letter, 
          and on the basis of such inquiries and procedures nothing came to 
          their attention that caused them to believe that:  (A) the 
          unaudited consolidated financial statements of the Company included 
          in the Registration Statement and Prospectus do not comply as to 
          form in all material respects with the applicable accounting 
          requirements of the 1934 Act and the 1934 Act Regulations or were 
          not fairly presented in conformity with generally accepted 
          accounting principles in the United States applied on a basis 
          substantially consistent with that of the audited financial 
          statements included therein, or (B) at a specified date not more 
          than five days prior to the date of such letter, there was any 
          change in the capital stock or any increase in long-term debt of 
          the Company or any decrease in the common shareholders' equity of 
          the Company other than for the declaration of regular quarterly 
          dividends, in each case as compared  with the amounts shown on the 
          most recent balance sheet of the Company included in the 
          Registration Statement and Prospectus or, during the  period from 
          the date of such balance sheet to a specified date not  more than 
          five days prior to the date of such letter, there were any 
          decreases, as compared with the corresponding period in the 
          preceding year, in operating revenues or net income of the Company, 
          except in each such case as set forth in or contemplated by the 
          Registration Statement and Prospectus or except for such exceptions 
          (e.g. inability to determine such decreases because of insufficient 
          accounting  information available after the date of such most 
          recent balance sheet) enumerated in such letter as shall have been 
          agreed to by the Representative and the Company.

              (iv)  In addition to the examination referred to in their report 
          included or incorporated by reference in the Registration Statement 
          and the Prospectus, and the limited procedures referred to in 
          clause (iii) above, they have carried out certain other specified 
          procedures, not constituting an audit, with respect to certain 
          amounts, percentages and financial information which are 

                                      21

<PAGE>

          included or incorporated by reference in the Registration Statement 
          and Prospectus and which are specified by the Agent, and have found 
          such amounts, percentages and financial information to be in 
          agreement with the relevant accounting, financial and other records 
          of the Company identified in such letter.

          (f)  ADDITIONAL COMFORT LETTER.  On the date hereof, the Agent 
     shall have received from Deloitte & Touche LLP a letter dated the date 
     hereof and in form and substance satisfactory to the Agent, to the effect 
     of Section 5(e)(i) and (ii).

          (g)  OPINION OF AGENT'S COUNSEL.  Sidley & Austin, as counsel for 
     the Agent, shall have furnished to the Agent the  date hereof such 
     opinions with respect to the validity of the Notes and with respect to 
     the Registration Statement, the Prospectus, and other related matters as 
     the Agent may reasonably require;

          (h)  FERC AND ICC ORDERS.  The orders of the FERC and ICC referred 
     to in Section 2(p) hereof shall be in full force and effect and no 
     proceedings to suspend the effectiveness of either such order shall be 
     pending or threatened;

          (i)  RATINGS.  Subsequent to the execution of this Agreement, there 
     shall not have been any decrease in the ratings of  any of the Company's 
     debt securities by Standard & Poor's Rating Service or Moody's Investors 
     Service Inc.; and

          (j)  NO MATERIAL ADVERSE CHANGE.  Subsequent to the date of the 
     most recent financial statements incorporated by reference in the 
     Prospectus, there shall have been no material adverse change in the 
     condition (financial or otherwise), business or results of operations of 
     the Company, except as set forth in the Registration Statement and the 
     Prospectus, including the documents incorporated by reference therein, 
     as of the effective date of this Agreement.

         (k)  OTHER DOCUMENTS.  On the date hereof and on each Settlement 
     Date with respect to any applicable Terms Agreement, counsel to the 
     Agent shall have been furnished with such documents and opinions as such 
     counsel may reasonably require for the purpose of enabling such counsel 
     to pass upon the issuance and sale of Notes as herein contemplated and 
     related proceedings, or in order to evidence the accuracy and 
     completeness of any of the representations and warranties, or the 
     fulfillment of any of the conditions, herein contained; and all 
     proceedings taken by the 

                                     22

<PAGE>

     Company in connection with the issuance and sale of Notes as herein 
     contemplated shall be satisfactory in form and substance to the 
     Agent and to counsel to the Agent.

    If any condition specified in this Section 5 shall not have been 
fulfilled when and as required to be fulfilled, this Agreement (or, at the 
option of the Agent, any applicable Terms Agreement) may be terminated by the 
Agent by notice to the Company at any time and any such termination shall be 
without liability of any party to any other party, except that the covenant 
regarding provision of an earnings statement set forth in Section 4(l) 
hereof, the provisions concerning payment of  expenses under Section 4(s) 
hereof, the indemnity and contribution agreement set forth in Section 9 
hereof, the provisions concerning the representations, warranties and 
agreements to survive delivery in Section 10 hereof and the provisions set 
forth under "Parties" of Section 14 hereof shall remain in effect.

    Section 6.  Conditions to the Obligations of the Company.  The obligations
of the Company to sell and deliver the Notes are subject to the following
conditions precedent:

         (a)  NO STOP ORDER.  At or before the date hereof, no stop order
    suspending the effectiveness of the Registration Statement nor any order
    directed to any document incorporated by reference in the Prospectus shall
    have been issued and prior to that time no stop order proceeding shall have
    been initiated or threatened by the SEC and no challenge shall have been
    made by the SEC to the accuracy or adequacy of any document incorporated by
    reference in the Prospectus; any request of the SEC for inclusion of
    additional information in the Registration Statement or the Prospectus or
    otherwise shall have been complied with; and

         (b)  FERC AND ICC ORDERS.  The orders of the FERC and the ICC referred
    to in Section (2)(a)(xi) hereof shall be in full force and effect and no
    proceeding to suspend the effectiveness of such order shall be pending or

<PAGE>

SECTION 7.    DELIVERY OF AND PAYMENT FOR NOTES SOLD THROUGH THE AGENT.

    Delivery of Notes sold through the Agent as agent shall be made by the 
Company to such Agent for the account of any purchaser only against payment 
therefor in immediately available funds.  In the event that a purchaser shall 
fail either to accept delivery of or to make payment for a Note on the date 
fixed for settlement, the  Agent shall promptly notify the Company and 
deliver the Note to the Company, and, if the Agent has theretofore paid the 
Company for such Note, the Company will promptly return such funds to the 
Agent.  If such failure occurred for any reason other than default by the 
Agent in the performance of its obligations hereunder, the Company will 
reimburse the Agent on an equitable basis for its loss of the use of the 
funds for the period such funds were credited to the Company's account.

SECTION 8     ADDITIONAL COVENANTS OF THE COMPANY.

    The Company covenants and agrees with the Agent that:

    (a)  REAFFIRMATION OF REPRESENTATIONS AND WARRANTIES.  Each acceptance by 
the Company of an offer for the purchase of Notes, and each delivery of Notes 
to the  Agent pursuant to a Terms Agreement, shall be deemed to be an 
affirmation by the Company that the representations and warranties of the 
Company contained in this Agreement and in any certificate theretofore 
delivered to the Agent pursuant hereto are true and correct at the time of 
such acceptance or sale, as the case may be, and an undertaking that such 
representations and warranties will be true and correct at the time of 
delivery to the purchaser or the agent of such purchaser, or to the Agent, of 
the Note or Notes relating to such acceptance or sale, as the case may be, as 
though made at and as of each such time (and it is understood that such 
representations and warranties shall relate to the Registration Statement and 
Prospectus as amended and supplemented to each such time).

    (b)  SUBSEQUENT DELIVERY OF CERTIFICATES.  Each time that the 
Registration Statement or the Prospectus shall be amended or supplemented 
(other than by an amendment or supplement providing  solely for a change in 
the interest rates of Notes or similar changes, and, unless the Agent  shall 
otherwise specify, other than by an amendment or supplement which relates 
exclusively to an offering of securities other than the Notes) or there is 
filed with the SEC any document incorporated by reference into the Prospectus 
(other than any Current Report on Form 8-K relating exclusively to the 
issuance of securities other than Notes under the Registration 


                                     24

<PAGE>

Statement, unless the Agent shall otherwise specify) or (if required pursuant 
to the terms of a Terms Agreement) the Company sells Notes to the Agent 
pursuant to a Terms Agreement, the Company shall furnish or cause to be 
furnished to the Agent forthwith a certificate dated the date of filing with 
the SEC of such supplement or document, the date of effectiveness of such 
amendment, or the date of such sale, as the case may be, in form satisfactory 
to the Agent to the effect that the statements contained in the certificate 
referred to in Section 5(d) hereof which was last furnished to the Agent is 
true and correct at the time of such amendment, supplement, filing or sale, 
as the case may be, as though made at and as of such time (except that such 
statements shall be deemed to relate to the Registration Statement and the 
Prospectus as amended and supplemented to such time) or, in lieu of such 
certificate, a certificate of the same tenor as the certificate referred to 
in said Section 5(d), modified as necessary to relate to the Registration 
Statement and the Prospectus as amended and supplemented to the time of 
delivery of such certificate.

    (c)  SUBSEQUENT DELIVERY OF LEGAL OPINIONS.  Each time that the 
Registration Statement or the Prospectus shall be amended or supplemented 
(other than by an amendment or supplement providing solely for a change in 
the interest rates of the Notes or similar changes or solely for the 
inclusion of additional financial information, and, unless the Agent shall 
otherwise specify, other than by an amendment or supplement which relates 
exclusively to an offering of securities other than the Notes) or there is 
filed with the SEC any document incorporated by reference into the Prospectus 
(other than any Current Report on Form 8-K or Quarterly Report on Form 10-Q, 
unless the Agent shall otherwise specify), or (if required pursuant to the 
terms of a Terms Agreement) the Company sells Notes to the Agent pursuant to 
a Terms Agreement, the Company shall furnish or cause to be furnished 
forthwith to the Agent and to counsel to the Agent a written opinion of John 
A. Rasmussen, Jr., Esq., counsel to the Company, or other counsel 
satisfactory to the Agent, dated the date of filing with the SEC of such 
supplement or document, the date of effectiveness  of such amendment, or the 
date of such sale, as the case may be, in form and substance satisfactory to 
the Agent, of the same tenor as the opinion referred to in Section 5(c) 
hereof, but modified, as necessary, to relate to the Registration Statement 
and the Prospectus as amended and supplemented to the time of delivery of 
such opinion; or, in lieu of such opinion, counsel last furnishing such 
opinion to the Agent shall furnish the Agent with a letter to the effect that 
the Agent may rely on such last opinion to the same extent as though it was 
dated the date of such letter authorizing reliance (except that 

                                     25

<PAGE>

statements in such last opinion shall be deemed to relate to the Registration 
Statement and the Prospectus as amended and supplemented to the time of 
delivery of such letter authorizing reliance).

    (d)  SUBSEQUENT DELIVERY OF COMFORT LETTERS.  Each time that the 
Registration Statement or the Prospectus shall be amended or supplemented to 
include additional financial information or there is filed with the SEC any 
document incorporated by reference into the Prospectus which contains 
additional financial information or, (if required pursuant to the terms of a 
Terms Agreement) the Company sells Notes to the Agent pursuant to a Terms 
Agreement, the Company shall cause Arthur Andersen LLP forthwith to furnish 
the Agent a letter, dated the date of effectiveness of such amendment, 
supplement or document with the SEC , or the date of such sale, as the case 
may be, in form satisfactory to the Agent, of the same tenor as the portions 
of the letter referred to in clauses (i) and (ii) of Section 5(e) hereof but 
modified to relate to the Registration Statement and Prospectus, as amended 
and supplemented to the date of such letter, and of the same general tenor as 
the portions of the letter referred to in clauses (iii) and (iv) of said 
Section 5(e) with such changes as may be necessary to reflect changes in the 
financial statements and other information derived from the accounting 
records of the Company; PROVIDED, HOWEVER, that if the Registration Statement 
or the Prospectus is amended or supplemented solely to include financial 
information as of and for a fiscal quarter, Arthur Andersen LLP may limit the 
scope of such letter to the unaudited financial statements included in such 
amendment or supplement unless any other information included therein of an 
accounting, financial or statistical nature is of such a nature that, in the 
reasonable judgment of the Agent, such letter should cover such other 
information.

    Section 9.  Indemnification.  (a) INDEMNIFICATION OF THE AGENT.  The 
Company agrees to indemnify and hold harmless the  Agent within the meaning 
of Section 15 of the 1933 Act as follows:

              (i)  against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement
         or alleged untrue statement of a material fact contained in the
         Registration Statement (or any amendment thereto), or the omission or
         alleged omission therefrom of a material fact necessary to make the
         statements therein not misleading or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Prospectus (or any amendment or supplement thereto) or the 
         omission or 


                                     26

<PAGE>

         alleged omission therefrom of a material fact necessary to make the
         statements therein, in the light of the circumstances under which
         they were made, not misleading; 

              (ii)  against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or investigation or proceeding
         by any governmental agency or body, commenced or threatened, or any
         claim whatsoever based upon any such untrue statement or omission, or
         any such alleged untrue statement or omission, if such settlement is
         effected with the written consent of the Company; and

              (iii) against any and all expense whatsoever, as incurred,
         (including, subject to Section 9(c) hereof, the fees and disbursements
         of counsel) reasonably incurred in investigating, preparing or
         defending against any litigation, or investigation or proceeding by
         any governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under (i) or (ii) above.

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss, 
liability, claim, damage or expense to the extent arising out of any untrue 
statement or omission or alleged untrue statement or omission made in 
reliance upon and in conformity with written information furnished to the 
Company by the Agent expressly for use in the Registration Statement (or any 
amendment thereto) or any preliminary prospectus or the Prospectus (or any 
amendment or supplement thereto); and PROVIDED, FURTHER, that this indemnity 
agreement with respect to any preliminary prospectus shall not inure to the 
benefit of the Agent from whom the person asserting any such losses, 
liabilities, claims, damages or expenses purchased Notes, or any person 
controlling the Agent, if a copy of the Prospectus (as then amended or 
supplemented if the Company shall have furnished any such amendment or 
supplement thereto, but excluding documents incorporated or deemed to be 
incorporated by reference therein) was not sent or given by or on behalf of 
the Agent to such person, if such is required by law, at or prior to the 
written confirmation of the sale of such Notes to such person and if the 
Prospectus (as so amended or supplemented, but excluding documents 
incorporated or deemed to be incorporated by reference therein) would have 
corrected the defect giving rise to such loss, liability, claim, damage or 
expense, it being understood that this 

                                     27

<PAGE>

proviso shall have no application if such defect shall have been corrected in 
a document which is incorporated or deemed to be incorporated by reference in 
the Prospectus.

         (b)  INDEMNIFICATION OF THE COMPANY.  The Agent agrees to indemnify
    and hold harmless the Company, its directors, each of its  officers who
    signed the Registration Statement, and each person, if any, who controls
    the Company within the meaning of Section 15 of the 1933 Act against any
    and all loss, liability, claim, damage and expense described in the
    indemnity contained in subsection (a) of this Section, as incurred, but
    only with respect to untrue statements or omissions, or alleged untrue
    statements or omissions, made in the Registration Statement (or any
    amendment thereto) or any preliminary prospectus or the Prospectus (or any
    amendment or supplement thereto) in reliance upon and in conformity with
    written information furnished to the Company by the Agent expressly for use
    in the Registration Statement (or any amendment thereto) or such
    preliminary prospectus or the Prospectus (or any amendment or supplement
    thereto).

         (c)  GENERAL.  Each indemnified party shall give prompt notice to each
    indemnifying party of any action commenced against it in respect of which
    indemnity may be sought hereunder, but failure so to notify an indemnifying
    party shall not relieve such indemnifying party from any liability which it
    may have otherwise than on account of this indemnity agreement.  An
    indemnifying party may participate at its own expense in the defense of
    such action.  In no event shall the indemnifying parties be liable for the
    fees and expenses of more than one counsel (in addition to any local
    counsel) for all indemnified parties in connection with any one action or
    separate but similar or related actions in the same jurisdiction arising
    out of the same general allegations or circumstances.

         (d)  CONTRIBUTION.  In order to provide for just and equitable
    contribution in circumstances in which the indemnity agreements provided
    for in this Section 9 are for any reason held to be unenforceable by the
    indemnified parties although applicable in accordance with their terms, the
    Company and the Agent shall contribute to the aggregate losses,
    liabilities, claims, damages and expenses of the nature contemplated by
    said indemnity agreements incurred by the Company and the Agent, as
    incurred, in such proportions that the Agent is responsible for that
    portion represented by the percentage that the total commissions and
    underwriting discounts received 

                                     28

<PAGE>

    by such Agent to the date of such liability bears to the total sales 
    price from the sale of Notes sold to or through such Agent to the date 
    of such liability  and the Company is  responsible for the balance; 
    PROVIDED, HOWEVER, that no person guilty of fraudulent misrepresentation 
    (within the meaning of Section 11(f) of the 1933 Act) shall be entitled 
    to contribution from any person who was not guilty of such fraudulent 
    misrepresentation.  For purposes of this Section, each person, if any, 
    who controls the Agent within the meaning of Section 15 of the 1933 Act 
    shall have the same rights to contribution as the Agent, and each director 
    of the Company and each officer of the Company who signed the Registration 
    Statement, and each person, if any, who controls the Company within the 
    meaning of Section 15 of 1933 Act, shall have the same rights to 
    contribution as the Company.

SECTION 10.   REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.

    All representations, warranties and agreements contained in this 
Agreement or in certificates of officers of the Company submitted pursuant 
hereto or thereto, shall remain operative and in full force and effect, 
regardless of any investigation made by or on behalf of the Agent or any 
controlling person of any Agent, or by or on behalf of the Company, and shall 
survive each delivery of and payment for any of the Notes.

SECTION 11.   TERMINATION.

     (a) TERMINATION OF THIS AGREEMENT.  This Agreement (excluding any Terms 
Agreement) may be terminated for any reason, at any time by either the 
Company or the Agent upon the giving of 30 days' written notice of such 
termination to the other party hereto.

    (b)  TERMINATION OF A TERMS AGREEMENT.  The Agent may terminate any Terms 
Agreement, immediately upon notice to the Company, at any time prior to the 
Settlement Date relating thereto (i) if there has been, since the date of 
such Terms Agreement or since the respective dates as of which information is 
given in the Registration Statement, any material adverse change in the 
condition, financial or otherwise, or in the earnings, business affairs or 
business prospects of the Company and its subsidiaries considered as one 
enterprise, whether or not arising in the ordinary course of business, or 
(ii) if there shall have occurred any material adverse change in the 
financial markets in the United States or any outbreak or escalation of 
hostilities or other national or international calamity or crisis the effect 
of which is

                                     29

<PAGE>


such as to make it, in the judgment of Agent, impracticable to market the 
Notes or enforce contracts for the  sale of the Notes, or (iii) if trading in 
any securities of the Company has been suspended by the SEC or a national 
securities exchange, or if trading generally on either the American Stock 
Exchange or the New York Stock Exchange shall have been suspended, or minimum 
or maximum prices for trading have been fixed, or maximum ranges for prices 
for securities have been required, by either of said exchanges or by order of 
the SEC or any other governmental authority, or if a banking moratorium shall 
have been declared by either Federal or New York authorities, or (iv) if the 
rating assigned by any nationally recognized securities rating agency to any 
debt securities of the Company as of the date of any applicable Terms 
Agreement shall have been lowered since that date or if any such rating 
agency shall have publicly announced that it has under surveillance or 
review, with possible negative implications, its rating of any debt 
securities of the Company, or (v) if there shall have come to the Agent's 
attention any facts that would cause the Agent to believe that the 
Prospectus, at the time it was required to be delivered to a purchaser of 
Notes, contained an untrue statement of a material fact or omitted to state a 
material fact necessary in order to make the statements therein, in light of 
the circumstances existing at the time of such delivery, not misleading.

    (c)  GENERAL.  In the event of any such termination, neither party will 
have any liability to the other party hereto, except that (i) the Agent shall 
be entitled to any commission earned in accordance with the third paragraph 
of Section 3(a) hereof, (ii) if at the time of termination (a) the Agent 
shall own any Notes purchased pursuant to a Terms Agreement with the 
intention of reselling them or (b) an offer to purchase any of the Notes has 
been accepted by the Company but the time of delivery to the purchaser or his 
agent of the Note or Notes relating thereto has not occurred, the covenants 
set forth in Sections 4 and 7 hereof shall remain in effect until such Notes 
are so resold or delivered, as the case may be, and (iii) the covenant set 
forth in Section 4(s) hereof, the indemnity and contribution agreements set 
forth in Section 9 hereof, and the provisions of Sections 4(s), 10 and 14 
hereof shall remain in effect.

                            MIDAMERICAN ENERGY FINANCING I



         This TRUST  AGREEMENT of MidAmerican Energy Financing I (the "Trust"),

         1.   The trust created hereby shall be known as "MidAmerican Energy
    Financing I", in which name the Trustees, or the Depositor to the extent
    provided herein, may conduct the business of the Trust, make and execute
    contracts, and sue and be sued.

         2.   The Depositor hereby assigns, transfers, conveys and sets over
    to the  Trustees the sum of $10.  The Trustees hereby acknowledge receipt
    of such amount in  trust from the Depositor, which amount shall constitute
    the initial trust estate.  The  Trustees hereby declare that they will hold
    the trust estate in trust for the Depositor.  It is the intention of the
    parties hereto that  the Trust  created hereby constitute  a business trust
    under Chapter 38 of Title 12 of the Delaware Code, 12 DEL. C. S.3801 ET
    SEQ. (the "Business Trust Act"), and that this document constitutes the
    governing instrument of  the Trust.  The Trustees are hereby authorized and
    directed to execute  and file a certificate of  trust with the Delaware
    Secretary of State in accordance with the provisions of the Business Trust
    Act.

         3.   The Depositor and the  Trustees will enter into an amended and
    restated Trust Agreement, satisfactory  to each such party and
    substantially in the form to be included as an  exhibit to  the 1933  Act
    Registration  Statement referred  to  below, to provide  for  the
    contemplated  operation  of  the Trust  created hereby and  the issuance of

    Prior to  the  execution and delivery  of  such  amended  and restated
    Trust  Agreement,  the Trustees  shall not have any duty or obligation
    hereunder or with respect to the trust  estate,  except as  otherwise
    required  by applicable law or  as may be  necessary to obtain  prior to
    such  execution  and  delivery  any  licenses,  consents  or  approvals
    required by applicable law or otherwise.

clauses (i) and (ii) above is required by the rules and regulations of the 
Commission, the Exchange or state securities or blue sky laws, to be executed 
on behalf of the Trust by one or more of  the Trustees, each of the 
Trustees, in  its or  his capacity as Trustee  of the Trust, is hereby 
authorized and, to the extent so required, directed to  join in any such 
filing  and to execute on behalf  of  the Trust any and  all  of the  
foregoing, it being understood that The First National Bank of Chicago and 
First Chicago Delaware Inc., in their capacities as Trustees of the Trust, 
respectively, shall not be required to join in any such filing or 
execute on behalf of the Trust any such document unless required by the 
rules and regulations of the Commission, the  Exchange or state securities 
or blue sky laws. In connection with all of the foregoing, the Depositor and 
each Trustee, solely in its or his capacity as Trustee of the Trust, hereby 
constitutes and appoints Phillip G. Lindner, Paul J. Leighton, and J. Sue

1934 Act Registration Statement, with the Commission, granting unto said 
attorneys-in-fact and agents full power and authority to do and perform each 
and every act and thing requisite and necessary to be  done in connection 
therewith, as fully to all intents and purposes as the Depositor or such 
Trustee might or could do in person, hereby ratifying and confirming all  
that said attorneys-in-fact and agents or any of them, or their respective 
substitute or substitutes, shall do or cause to be done by virtue hereof.

     any  filing referred to in clauses (i) and (ii)  above is required by the
     rules  and regulations of the Commission, the Exchange or state securities
     or blue sky laws, to be executed on behalf of the Trust by one or more of

     or his true and lawful attorneys-in-fact and agents, with full power of
     substitution  and resubstitution, for the Depositor or such Trustee or in
     the Depositor's or such  Trustee's name, place and stead,  in any and all
     capacities,  to sign  any and  all amendments  (including post-effective
     amendments) to the 1933 Act Registration Statement and the 1934  Act
     Registration  Statement and to  file the  same,  with  all exhibits
     thereto,  and other  documents in  connection therewith  and  in connection
     with the  filing  of the  1933 Act Registration Statement and the  1934 Act
     Registration  Statement, with  the Commission,  granting unto  said
     attorneys-in-fact  and agents full power and authority to do and perform

     Depositor or such Trustee might or could do in person, hereby ratifying and
     confirming all  that said attorneys-in-fact and agents  or any of them, or
     their respective substitute  or substitutes, shall do or cause to be done

          notice of issuance of any Preferred Securities and to file or
          cause the Administrative Trustees to file thereafter with such

          from time to time to maintain such listing;

            (iv)    to prepare for filing by the Trust with the Commission

          carry out any of the foregoing activities.

          (d)   Notwithstanding anything herein to the contrary, the
Administrative Trustees are authorized and directed to conduct the affairs of
the Trust and to operate the Trust so that the Trust will not be deemed to be an
"investment company" required to be registered under the Investment Company Act
of 1940, as amended, or classified other than as a "grantor trust" for United
States federal income tax purposes and not as an association taxable as a
corporation and so that the Debentures will be treated as indebtedness of the
Depositor for United States federal income tax purposes.  In this connection,
subject to the provisions of Section 10.03, the Depositor and the Administrative
Trustees are authorized to take any action, not inconsistent with applicable
law, the certificate of trust filed with the Secretary of State of the State of
Delaware with respect to the Trust (as amended or restated from time to time,

          Section 3.01.  Payment Account.

          (a)   On or prior to the Closing Date, the Property Trustee shall
establish the Payment Account.  The Property Trustees and the Paying Agent
appointed by the Administrative Trustees shall have exclusive control and sole
right of withdrawal with respect to the Payment Account for the purpose of
making deposits in and withdrawals from the Payment Account in accordance with
this Trust Agreement.  All monies and other property deposited or held from time
to time in the Payment Account shall be held by the Property Trustee in the

for distribution as herein provided, including (and subject to) any priority of
payments provided for herein.

          (b)   The Property Trustee shall deposit in the Payment Account,

                            Distributions; Redemption

          Section 4.01.  Distributions.

          (a)   Distributions on the Trust Securities shall be cumulative, and
will accumulate whether or not there are funds of the Trust available for the
payment of Distributions.  Distributions shall accrue from the Closing Date,
and, except in the event that the Depositor exercises its right to extend the
interest payment period for the Debentures pursuant to Section 311 of the
Subordinated Indenture, shall be payable quarterly in arrears on March 1, June
1, September 1 and December 1 of each year, commencing on ___________, 199_.  If
any date on which Distributions are otherwise payable on the Trust Securities is
not a Business Day, then the payment of such Distribution shall be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay) except that, if such Business Day is in
the next succeeding calendar year, payment of such Distribution shall be made on
the immediately preceding Business Day, in each case, with the same force and
effect as if made on such date (each date on which distributions are payable in
accordance with this Section 4.01(a) a "Distribution Date").

          (b)   Distributions payable on the Trust Securities shall be fixed at
a rate of  _____% per annum of the Liquidation Amount of the Trust Securities.
The amount of Distributions payable for any full quarterly period shall be
computed on the basis of twelve

                                      -17-

<PAGE>

30-day months and a 360-day year and for any period shorter than a full month,
on the basis of the actual number of days elapsed.  If the interest payment
period for the Debentures is extended pursuant to Section 311 of the
Subordinated Indenture, then Distributions on the Preferred Securities will be
deferred for the period equal to the extension of the interest payment period
for the Debentures and the rate per annum at which Distributions on the Trust
Securities accumulate shall be increased by an amount such that the aggregate
amount of Distributions that accumulate on all Trust Securities during any such
extended interest payment period is equal to the aggregate amount of interest
(including, to the extent permitted by law, interest payable on unpaid interest
at the percentage rate per annum set forth above, compounded quarterly) that
accrues during any such extended interest payment period on the Debentures.  The
amount of Distributions payable for any period shall include the Additional
Amounts, if any.

          (c)   Distributions on the Trust Securities shall be made and shall
be deemed payable on each Distribution Date only to the extent that the Trust
has funds available in the Payment Account for the payment of such
Distributions.

          (d)   Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which
shall be 15 days prior to the relevant Distribution Date.

          Section 4.02.  Redemption.

          (a)   On each Debenture Redemption Date and on the Maturity Date of
the Debentures, the Property Trustee will be required to redeem a Like Amount of
Trust Securities at the Redemption Price plus accumulated and unpaid
Distributions to the date of such payment.

          (b)   Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register.  All notices of
redemption or liquidation shall state:

            (i)     the Redemption Date;

            (ii)    the Redemption Price and the amount of accumulated and
          unpaid Dividends to be paid on the Redemption Date;

            (iii) the CUSIP number;

            (iv)    if less than all the Outstanding Trust Securities are to be
          redeemed, the identification and the total Liquidation Amount of the
          particular Trust Securities to be redeemed; and

                                      -18-

<PAGE>


            (v)     that on the Redemption Date the Redemption Price plus
          accumulated and unpaid Distributions to the date of such payment will
          become due and payable upon each such Trust Security to be redeemed
          and that interest thereon will cease to accrue on and after said date.

          (c)   The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price plus accumulated and unpaid Distributions to
the date of such payment with the proceeds from the contemporaneous redemption
of Debentures.  Redemptions of the Trust Securities shall be made and the
Redemption Price plus accumulated and unpaid Distributions to the date of such
payment shall be deemed payable on each Redemption Date only to the extent that
the Trust has funds immediately available in the Payment Account for such
payment.

          (d)   If the Property Trustee gives a notice of redemption in respect
of any Preferred Securities, then, by 12:00 noon, New York time, on the
Redemption Date, subject to Section 4.02(c), the Property Trustee shall
irrevocably deposit with the Paying Agent (or Securities Depository, in the
event the Preferred Securities are book-entry only) funds sufficient to pay the
applicable Redemption Price plus accumulated and unpaid Distributions to the
date of such payment and will give the Paying Agent (or Securities Depository,
as the case may be) irrevocable instructions and authority to pay the Redemption
Price plus accumulated and unpaid Distributions to the date of such payment to
the Holders thereof upon surrender of their Preferred Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates.  If notice of redemption shall have been given and funds
deposited as required, then on the Redemption Date, all rights of
Securityholders holding Trust Securities so called for redemption will cease,
except the right of such Securityholders to receive the Redemption Price plus
accumulated and unpaid Distributions to the date of such payment, but without
interest thereon, and such Trust Securities will cease to be outstanding.  In
the event that any Redemption Date is not a Business Day, then payment of the
Redemption Price payable on such date plus accumulated and unpaid Distributions
to such date shall be made on the next succeeding day which is a Business Day
(and without any interest or other payment in respect of any such delay).  In
the event that payment of the Redemption Price plus accumulated and unpaid
Distributions in respect of any Trust Securities called for redemption is
improperly withheld or refused and not paid either by the Trust or by the
Depositor pursuant to the Guarantee, Distributions on such Trust Securities will
continue to accrue, at the then applicable rate, from the Redemption Date
originally established by the Trust for such Trust Securities to the date such
Redemption Price plus accumulated and unpaid Distributions is actually paid, in
which case the actual payment date will be deemed the date fixed for redemption
for purposes of calculating the Redemption Price plus accumulated and unpaid
Distributions to such date.

                                      -19-

<PAGE>

          (e)   Payment of the Redemption Price on the Trust Securities shall
be made to the Holders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be the fifteenth day
prior to the Redemption Date.

          (f)   If less than all the Outstanding Trust Securities are to be
redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust
Securities to be redeemed shall be allocated 3% to the Common Securities and 97%
to the Preferred Securities.  The particular Preferred Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Preferred Securities not previously called
for redemption, by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for a redemption of portions
(equal to $25 or integral multiples thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $25.  The Property Trustee
shall promptly notify the Transfer Agent and Registrar in writing of the
Preferred Securities selected for redemption and, in the case of any Preferred
Securities selected for partial redemption, the Liquidation Amount thereof to be
redeemed.  For all purposes of this Trust Agreement, unless the context
otherwise requires, all provisions relating to the redemption of Preferred
Securities shall relate, in the case of any Preferred Securities redeemed or to
be redeemed only in part, to the portion of the Liquidation Amount of Preferred
Securities which has been or is to be redeemed.

          Section 4.03.  Subordination of Common Securities.

          (a) Payment of Distributions (including Additional Amounts, if
applicable) on, and the Redemption Price plus accumulated and unpaid
distributions of, the Trust Securities, as applicable, shall be made pro rata
based on the Liquidation Amount of the Trust Securities; provided, however, that
if on any Distribution Date or Redemption Date a Debenture Event of Default
shall have occurred and be continuing, no payment of any Distribution (including
Additional Amounts, if applicable) on, or Redemption Price of, any Common
Security, and no other payment on account of the redemption, liquidation or
other acquisition of Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions (including Additional Amounts,
if applicable) on all Outstanding Preferred Securities for all distribution
periods terminating on or prior thereto, or in the case of payment of the
Redemption Price plus accumulated and unpaid Distributions the full amount of
such Redemption Price plus accumulated and unpaid Distributions on all
Outstanding Preferred Securities, shall have been made or provided for, and all
funds immediately available to the Property Trustee shall first be applied to
the payment in full in cash of all Distributions (including Additional Amounts,
if applicable) on, or Redemption Price plus accumulated and unpaid Distributions
of, Preferred Securities then due and payable.

          (b) In the case of the occurrence of any Event of Default resulting
from a Debenture Event of Default, the Holder of Common Securities will be
deemed to have waived any such Event of Default under this Trust Agreement until
the effect of all such Events of Default with respect to the Preferred
Securities have been cured, waived or otherwise eliminated.  Until any such
Events of Default under this Trust Agreement with respect to the

                                      -20-

<PAGE>

Preferred Securities have been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the Holders of the Preferred
Securities and not the Holder of the Common Securities, and only the Holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

          Section 4.04.  Payment Procedures.  Payments in respect of the
Preferred Securities shall be made by check mailed to the address of the Person
entitled thereto as such address shall appear on the Securities Register or, if
the Preferred Securities are held by a Securities Depository, such Distributions
shall be made to the Securities Depository, which shall credit the relevant
Persons' accounts at such Securities Depository on the applicable distribution
dates.  Payments in respect of the Common Securities shall be made in such
manner as shall be mutually agreed between the Administrative Trustees and the
Holder of the Common Securities.

          Section 4.05.  Tax Returns and Reports. The Administrative Trustees
shall prepare (or cause to be prepared), at the Depositor's expense and
direction, and file all United States federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust.  In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared or filed) the Internal Revenue Service Form 1041 (or
any successor form) required to be filed in respect of the Trust in each taxable
year of the Trust and (b) prepare and furnish (or cause to be prepared and
furnished) to each Securityholder the related Internal Revenue Service Form
1099, or any successor form or the information required to be provided on such
form.  The Administrative Trustees shall provide the Depositor and the Property
Trustee with a copy of all such returns, reports and schedules promptly after
such filing or furnishing.  The Trustees shall comply with United States federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

                          Trust Securities Certificates

          Section 5.01.  Initial Ownership.  Upon the creation of the Trust by
the contribution by the Depositor referred to in Section 2.03 and until the
issuance of the Trust Securities, and at any time during which no Trust
Securities are outstanding, the Depositor shall be the sole beneficial owner of
the Trust.

          Section 5.02.  The Trust Securities Certificates.  The Trust
Securities Certificates shall be issued in denominations of $25 Liquidation
Amount and integral multiples thereof.  Subject to Section 2.04 relating to the
original issuance of the Preferred Securities Certificate registered in the name
of the nominee of The Depository Trust Company, the Trust Securities
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of at least one Administrative Trustee and, if executed on behalf of
the Trust by facsimile
                                      -21-

<PAGE>

signature, countersigned by a Transfer Agent or its agent.  Trust Securities 
Certificates bearing the manual signatures of individuals who were, at the 
time when such signatures shall have been affixed, authorized to sign on 
behalf of the Trust and, if executed on behalf of the Trust by facsimile 
signature, countersigned by a Transfer Agent or its agent, shall be validly 
issued and entitled to the benefits of this Trust Agreement, notwithstanding 
that such individuals or any of them shall have ceased to be so authorized 
prior to the delivery of such Trust Securities Certificates or did not hold 
such offices at the date of delivery of such Trust Securities Certificates.  
A transferee of a Trust Securities Certificate shall become a Securityholder, 
and shall be entitled to the rights and subject to the obligations of a 
Securityholder hereunder, upon due registration of such Trust Securities 
Certificate in such transferee's name pursuant to Section 5.04.

          Section 5.03.  Execution and Delivery of Trust Securities
Certificates.  On the Closing Date, the Administrative Trustees shall cause
Trust Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.04 and 2.05, to be executed on behalf of the Trust, and in the case
of Preferred Securities executed by facsimile signature, countersigned by a
Transfer Agent or its agent, and delivered to or upon the written order of the
Depositor signed by its chairman of the board, any of its vice presidents or its
Treasurer, without further corporate action by the Depositor, in authorized
denominations.  The Depositor agrees to indemnify, defend and hold each Transfer
Agent harmless against any and all costs and liabilities incurred without
negligence arising out of or in connection with any such countersigning by it.

          Section 5.04.  Registration of Transfer and Exchange of Preferred
Securities Certificates.  The Registrar shall keep or cause to be kept, at its
principal corporate office, a Securities Register in which, subject to such
reasonable regulations as it may prescribe, the Registrar shall provide for the
registration of Preferred Securities Certificates and the Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided.

          Upon surrender for registration of transfer of any Preferred
Securities Certificate at the office or agency maintained pursuant to Section
5.08, the Administrative Trustees, or any one of them, shall execute on behalf
of the Trust by manual or facsimile signature and, if executed on behalf of the
Trust by facsimile signature, cause a Transfer Agent or its agent to countersign
and deliver, in the name of the designated transferee or transferees, one or
more new Preferred Securities Certificates in authorized denominations of a like
aggregate Liquidation Amount.  At the option of a Holder, Preferred Securities
Certificates may be exchanged for other Preferred Securities Certificates in
authorized denominations of the same class and of a like aggregate Liquidation
Amount upon surrender of the Preferred Securities Certificates to be exchanged
at the office or agency maintained pursuant to Section 5.08.

          Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Administrative Trustees and a
Transfer Agent duly executed by the Holder or such Holder's attorney duly
authorized in writing.  Each Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be canceled and subsequently disposed
of by the Administrative Trustees in accordance with customary practice.  The
Trust shall not be required to (i) issue, register the transfer of, or exchange
any Preferred Securities during a period beginning at the opening of business 15
calendar days before the day of mailing of a notice of redemption of any
Preferred Securities called for redemption and ending at the close of business
on the day of such mailing or (ii) register the transfer of or exchange any
Preferred Securities so selected for redemption, in whole or in part, except the
unredeemed portion of any such Preferred Securities being redeemed in part.

          No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but a Transfer Agent may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Preferred Securities
Certificates.

          Section 5.05.  Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.   If (a) any mutilated Trust Securities Certificate shall be
surrendered to a Transfer Agent, or if a Transfer Agent shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate and (b) there shall be delivered to the Transfer Agent and the
Administrative Trustees such security or indemnity as may be required by them to
save each of them and the Depositor harmless, then in the absence of notice that
such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust, shall execute by manual or facsimile signature and, if execution on
behalf of the Trust is by facsimile signature, countersigned by a Transfer
Agent; and the Administrative Trustees, or any one of them, shall make available
for delivery, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Trust Securities Certificate, a new Trust Securities Certificate of
like class, tenor and denomination.  In connection with the issuance of any new
Trust Securities Certificate under this Section, the Administrative Trustees or
the Transfer Agent may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection therewith.  Any
duplicate Trust Securities Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

          Section 5.06.  Persons Deemed Securityholders.  Prior to due
presentation of a Trust Securities Certificate for registration of transfer, the
Trustees and the Registrar shall be entitled to treat the Person in whose name
any Trust Securities Certificate shall be registered in the Securities Register
as the owner of such Trust Securities Certificate for the purpose of receiving
Distributions and for all other purposes whatsoever, and neither the Trustee nor
the Registrar shall be bound by any notice to the contrary.

          Section 5.07.  Access to List of Securityholders' Names and Addresses.
The Administrative Trustees shall furnish or cause to be furnished (x) to the
Depositor, within 15 days after receipt by any Administrative Trustee of a
request therefor from the Depositor in writing and (y) to the Property Trustee,
promptly after receipt by any Administrative Trustee of a request therefor from
the Property Trustee in writing in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, a list, in such form as
the Depositor or the Property Trustee may reasonably require, of the names and
addresses of the Securityholders as of the most recent Record Date.  If Holders
of Trust Securities Certificates evidencing ownership at such time and for the
previous six months not less than 25% of the outstanding aggregate Liquidation
Amount apply in writing to any Administrative Trustee, and such application
states that the applicants desire to communicate with other Securityholders with
respect to their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders.  Each Holder, by receiving and holding a Trust Securities
Certificate, shall be deemed to have agreed not to hold either the Depositor or
the Administrative Trustees accountable by reason of the disclosure of its name
and address, regardless of the source from which such information was derived.

          Section 5.08.  Maintenance of Office or Agency.  The Company shall or
shall cause the Transfer Agent to maintain in the Borough of Manhattan, The City
of New York, an office or offices or agency or agencies where Preferred
Securities Certificates may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company or the Transfer
Agent in respect of the Trust Securities Certificates may be served.  The
Company initially designates the Corporate Trust Office of the Property Trustee
as its office for such purposes.  The Company shall or shall cause the Transfer
Agent to give prompt written notice to the Depositor, the Property Trustee and
to the Securityholders of any change in any such office or agency.

          Section 5.09.  Appointment of Paying Agent.  The Paying Agent shall
make distributions to Securityholders from the Payment Account and shall report
the amounts of such distributions to the Administrative Trustees and the
Property Trustee.  Any Paying Agent shall have the revocable power to withdraw
funds from the Payment Account for the purpose of making the Distributions
referred to above.  The Property Trustee shall be entitled to rely upon a
certificate of the Paying Agent stating in effect the amount of such funds so to
be withdrawn and that same are to be applied by the Paying Agent in accordance
with this Section 5.09.  The Administrative Trustees or any one of them may
revoke such power and remove the Paying Agent if the Administrative Trustee or
any one of them determines in its sole discretion that the Paying Agent shall
have failed to perform its obligations under this Trust Agreement in any
material respect.  The Paying Agent may choose any co-paying agent that is
acceptable to the Administrative Trustees and the Depositor.  The Paying Agent
shall be permitted to resign upon 30 days' written notice to the Administrative
Trustees and the Depositor.  In the event of the removal or resignation of the
Paying Agent, the Administrative

                                      -24-

<PAGE>

Trustees shall appoint a successor that is reasonably acceptable to the Property
Trustee and the Depositor to act as Paying Agent (which shall be a bank, trust
company or an Affiliate of the Depositor).  The Administrative Trustees shall
cause such successor Paying Agent or any additional Paying Agent appointed by
the Administrative Trustees to execute and deliver to the Trustees an instrument
in which such successor Paying Agent or additional Paying Agent shall agree with
the Trustees that as Paying Agent, such successor Paying Agent or additional
Paying Agent will hold all sums, if any, held by it for payment to the
Securityholders in trust for the benefit of the Securityholders entitled thereto
until such sums shall be paid to such Securityholders.  The Paying Agent shall
return all unclaimed funds to the Property Trustee and upon resignation or
removal of a Paying Agent such Paying Agent shall also return all funds in its
possession to the Property Trustee.  The provisions of Sections 8.01, 8.03 and
8.06 shall apply to the Paying Agent appointed hereunder, and the Paying Agent
shall be bound by the requirements with respect to paying agents of securities
issued pursuant to the Trust Indenture Act.  Any reference in this Trust
Agreement to the Paying Agent shall include any co-paying agent unless the
context requires otherwise.

          Section 5.10.  Ownership of Common Securities by Depositor.  On the
Closing Date and on each other date provided for in Section 2.05, the Depositor
shall acquire, and thereafter retain, beneficial and record ownership of the
Common Securities.  Any attempted transfer of the Common Securities shall be
void.  The Administrative Trustees shall cause each Common Securities
Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE".  Common Securities Certificates representing
the Common Securities shall be issued to the Depositor in the form of a
typewritten or definitive Common Securities Certificate.

          Section 5.11.  Definitive Preferred Securities Certificates.  The
Definitive Preferred Securities Certificates shall be typewritten, printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Administrative Trustees, as evidenced by the execution thereof
by the Administrative Trustees, or any one of them.  The Trust shall issue no
Securities in bearer form.

          Section 5.12.  Book-Entry System.  Some or all of the Preferred
Securities may be registered in the name of the Securities Depository or a
nominee therefor, and held in the custody of the Securities Depository.  In such
event, a single certificate will be issued and delivered to the Securities
Depository for such Preferred Securities, in which case the Owners of such
Preferred Securities will not receive physical delivery of certificates for
Preferred Securities.  Except as provided herein, all transfers of beneficial
ownership interests in such Preferred Securities will be made by book-entry
only, and no investor or other party purchasing, selling or otherwise
transferring beneficial ownership of the Preferred Securities will receive, hold
or deliver any certificate for Preferred Securities.  The Depositor, the
Trustees and the Paying Agent will recognize the Securities Depository or its
nominee as the Holder of Preferred Securities for all purposes, including
notices and voting; PROVIDED, that solely for the purposes of determining
whether the Holders of the requisite amount of Preferred Securities have voted
on any matter provided for in this Trust Agreement, with


                                      -25-

<PAGE>

respect to the vote by Owners of Preferred Securities registered in the name of
a Securities Depository, or its nominee, the Trustees may conclusively rely on,
and shall be protected in relying on, any written instrument (including a proxy)
delivered to the Trustees by such Securities Depository setting forth the
Owners' votes or assigning the right to vote on any matter to any other Persons
either in whole or in part.

          The Administrative Trustees, at the direction and expense of the
Depositor, may from time to time appoint a Securities Depository or a successor
thereto and enter into a letter of representations or other agreement with such
Securities Depository to establish procedures with respect to the Preferred
Securities.  Any Securities Depository shall be a Clearing Agency.

          The Depositor and the Trustees covenant and agree to meet the
requirements of a Securities Depository for the Preferred Securities with
respect to required notices and other provisions of the letter of
representations or agreement executed with respect to such Preferred Securities.

          Whenever the beneficial ownership of any Preferred Securities is
determined through the books of a Securities Depository, the requirements in
this Trust Agreement of holding, delivering or transferring such Preferred
Securities shall be deemed modified with respect to such Preferred Securities to
meet the requirements of the Securities Depository with respect to actions of
the Trustees, the Depositor and the Paying Agent.  Any provisions hereof
permitting or requiring delivery of such Preferred Securities shall, while such
Preferred Securities are in a book-entry system, be satisfied by the notation on
the books of the Securities Depository in accordance with applicable state law.

          Section 5.13.  Rights of Securityholders.  (a) The legal title to the
Trust Property is vested exclusively in the Property Trustee (in its capacity as
such) in accordance with Section 2.09, and the Securityholders shall not have
any right or title therein other than an undivided beneficial interest in the
assets of the Trust conferred by their Trust Securities and they shall have no
right to call for any partition or division of property, profits or rights of
the Trust except as described below.  The Trust Securities shall be personal
property giving only the rights specifically set forth therein and in this Trust
Agreement.  The Preferred Securities shall have no preemptive or similar rights
and when issued and delivered to Securityholders against payment of the purchase
price therefor will be fully paid and nonassessable interests in the Trust.

          (b)  For so long as any Preferred Securities remain Outstanding, if,
upon a Debenture Event of Default that relates to the Debentures, the Debenture
Trustee fails or the holders of not less than 33% in principal amount of the
Debentures then outstanding fail to declare the principal of the Debentures to
be immediately due and payable, the Holders of at least 33% in Liquidation
Amount of the Preferred Securities then Outstanding shall have such right by a
notice in writing to the Depositor and the Debenture Trustee; and upon any such
declaration such principal amount of and the accrued interest on the Debentures
shall become

                                      -26-

<PAGE>

immediately due and payable, provided that the payment of principal and interest
on the Debentures shall remain subordinated to the extent provided in the
Subordinated Indenture.

          (c)  For so long as any Preferred Securities remain Outstanding, if
the holders of the Debentures fail to waive any past Debenture Event of Default
under the Subordinated Indenture and its consequences with respect to the
Debentures, the Holders of not less than a majority in Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any such past default and its consequences with respect to the
Debentures, except a default in the payment of principal, premium or interest or
a default in respect of a covenant or provision which under the Subordinated
Indenture cannot be modified or amended without the consent of the holder of
each outstanding Debenture.  No such rescission shall affect any subsequent
default or impair any right consequent thereon.

          (d)  For so long as any Preferred Securities remain Outstanding, to
the fullest extent permitted by law and subject to the terms of this Trust
Agreement and the Subordinated Indenture, upon a Debenture Event of Default
specified in Section 801(a) or 801(b) of the Supplemental Indenture, any Holder
of Preferred Securities shall have the right to institute a proceeding directly
against the Depositor, pursuant to Section 808 of the Subordinated Indenture,
for enforcement of payment to such Holder of the principal amount of or interest
on Debentures having a principal amount equal to the Liquidation Amount of the
Preferred Securities of such Holder (a "Direct Action").  The Depositor will be
subrogated to the rights of any such Holder to the extent of payment made to
such Holder pursuant to this Section 5.13(d).

     (e)  Except as set forth in this Section 5.13, the Holders of Preferred
Securities shall have no right to exercise directly any right or remedy
available to the holders of, or in respect of, the Debentures.

          Section 5.14.  Agreed Tax Treatment.  Each Preferred Security 
issued hereunder shall provide that the Company and, by its acceptance of a 
Preferred Security or a beneficial interest therein, the Owner of, and any 
Person that acquires a beneficial interest in, such Preferred Security agree 
that, for United States federal, state, and local tax purposes, it is 
intended that such Preferred Security constitute an undivided interest in 
indebtedness and agree to treat such Preferred Security accordingly for such 
purposes.

                                   ARTICLE VI.

                    Acts of Securityholders; Meetings; Voting

          Section 6.01.  Limitations on Voting Rights.

          (a)   Except as provided in this Section 6.01, in Section 10.03 and
as otherwise required by law, no Holder of Preferred Securities shall have any
right to vote or in any manner otherwise control the administration, operation
and management of the Trust or the

                                      -27-

<PAGE>

obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association.

          (b)   So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 813 of
the Subordinated Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable or
(iv) consent to any amendment, modification or termination of the Subordinated
Indenture or the Debentures, where such consent shall be required, without, in
each case, obtaining the prior approval of the Holders of at least 66 2/3% of
the aggregate Liquidation Amount of the Outstanding Preferred Securities;
provided, however, that where a consent under the Subordinated Indenture would
require the consent of each holder of Debentures affected thereby, no such
consent shall be given by any Trustee without the prior written consent of each
holder of Preferred Securities.  The Trustees shall not revoke any action
previously authorized or approved by a vote of the Preferred Securities, except
pursuant to a subsequent vote of the Preferred Securities.  The Property Trustee
shall notify all Holders of the Preferred Securities of any notice of default
received from the Debenture Trustee with respect to the Debentures.  In addition
to obtaining the foregoing approvals of the Holders of the Preferred Securities,
prior to taking any of the foregoing actions, the Property Trustee shall, at the
expense of the Depositor, obtain an Opinion of Counsel experienced in such
matters to the effect that the Trust will be classified as a "grantor trust" and
not as an association taxable as a corporation for United States federal income
tax purposes on account of such action.

          (c)   If any proposed amendment to the Trust Agreement provides for,
or the Trustees otherwise propose to effect, (i) any action that would
materially adversely affect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least 66 2/3% in Liquidation
Amount of the Outstanding Preferred Securities.  No amendment to this Trust
Agreement may be made if, as a result of such amendment, the Trust would not be
classified as a "grantor trust" but as an association taxable as a corporation
for United States federal income tax purposes.

          Section 6.02.  Notice of Meetings.  Notice of all meetings of the
Holders of Preferred Securities, stating the time, place and purpose of the
meeting, shall be given by the Administrative Trustees pursuant to Section 10.08
to each Holder of a Preferred Security, at his registered address, at least 15
days and not more than 90 days before the meeting.  At any such meeting, any
business properly before the meeting may be so considered whether or not

                                      -28-

<PAGE>

stated in the notice of the meeting.  Any adjourned meeting may be held as
adjourned without further notice.

          Section 6.03.  Meetings of Holders of Preferred Securities.  No annual
meeting of Securityholders is required to be held.  The Administrative Trustees,
however, shall call a meeting of Securityholders to vote on any matter upon the
written request of the Holders of 25% of the then Outstanding Preferred
Securities (based upon their aggregate Liquidation Amount) and may, at any time
in their discretion, call a meeting of Holders of Preferred Securities to vote
on any matters as to which the Holders of Preferred Securities are entitled to
vote.

          Holders of 50% of the then Outstanding Preferred Securities (based
upon their aggregate Liquidation Amount), present in person or by proxy, shall
constitute a quorum at any meeting of Securityholders.

          If a quorum is present at a meeting, an affirmative vote by the
Holders of Preferred Securities present, in person or by proxy, holding more
than the lesser of (x) 66 2/3% of the then Outstanding Preferred Securities
(based upon their aggregate Liquidation Amount) held by the Holders of then
Outstanding Preferred Securities present, either in person or by proxy, at such
meeting and (y) 50% of the Outstanding Preferred Securities (based upon their
aggregate Liquidation Amount) shall constitute the action of the
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

          Section 6.04.  Voting Rights.  Securityholders shall be entitled to
one vote for each $25 of Liquidation Amount represented by their Trust
Securities in respect of any matter as to which such Securityholders are
entitled to vote.

          Section 6.05.  Proxies, Etc.  At any meeting of Securityholders, any
Securityholder entitled to vote thereat may vote by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken.  Only Securityholders of record shall be
entitled to vote.  When Trust Securities are held jointly by several Persons,
any one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities.  A proxy purporting to be executed by or on behalf of
a Securityholder shall be deemed valid unless challenged at or prior to its
exercise, or, if earlier, until eleven months after it is sent and the burden of
proving invalidity shall rest on the challenger.

          Section 6.06.  Securityholder Action by Written Consent.  Any action
which may be taken by Securityholders at a meeting may be taken without a
meeting if Securityholders holding more than a majority of all Outstanding Trust
Securities entitled to

                                      -29-

<PAGE>

vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing (based upon their aggregate Liquidation Amount).

          Section 6.07.  Record Date for Voting and Other Purposes.  For the
purposes of determining the Securityholders who are entitled to notice of and to
vote at any meeting or by written consent, or to participate in any Distribution
on the Trust Securities in respect of which a record date is not otherwise
provided for in this Trust Agreement, or for the purpose of any other action,
the Administrative Trustees may from time to time fix a date, not more than 90
days prior to the date of any meeting of Securityholders or the payment of
Distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

          Section 6.08.  Acts of Securityholders.  Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Securityholders in person or by an agent duly
appointed in writing; and, except as otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to the Administrative Trustees.  Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.01) conclusive in favor of the Trustees, if made in the manner provided in
this Section.

          The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee deems sufficient.

          The ownership of Preferred Securities shall be proved by the
Securities Register.

          Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done,

                                      -30-

omitted or suffered to be done by the Trustees or the Trust in reliance thereon,
whether or not notation of such action is made upon such Trust Security.

          Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such Liquidation Amount.

          If any dispute shall arise between or among the Securityholders and
the Administrative Trustees with respect to the authenticity, validity or
binding nature of any request, demand, authorization, direction, consent, waiver
or other Act of such Securityholder or Trustee under this Article VI, then the
determination of such matter by the Property Trustee shall be conclusive with
respect to such matter.

          Section 6.09.  Inspection of Records.  Subject to Section 5.07
concerning access to the list of Securityholders, upon reasonable notice to the
Administrative Trustees and the Property Trustee, the other records of the Trust
shall be open to inspection by Securityholders during normal business hours for
any purpose reasonably related to such Securityholder's interest as a
Securityholder.

         Section 8.01.  Certain Duties and Responsibilities.


                                         -32-

<PAGE>

         (a)  The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, the
Trust Indenture Act, and no implied covenants or obligations shall be read into
this Trust Agreement against any of the Trustees.  Notwithstanding the
foregoing, no provision of this Trust Agreement shall require any of the
Trustees 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.  No Trustee, other than the
Property Trustee, shall be liable for its acts or omissions hereunder unless as
a result of its gross negligence or willful misconduct.  Notwithstanding
anything contained in this Trust Agreement to the contrary, the duties and
responsibilities of the Property Trustee under this Trust Agreement shall be
subject to the protections, exculpations and limitations on liability afforded
to the Property Trustee under the provisions of the Trust Indenture Act and, to
the extent applicable, Rule 3A-7 under the Investment Company Act of 1940, as
amended, or any successor rule thereunder.  Whether or not therein expressly so
provided, every provision of this Trust Agreement relating to the conduct or
affecting the liability of or affording protection to the Trustees shall be
subject to the provisions of this Section.

         (b)  All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the income and proceeds
from the Trust Property and only to the extent that there shall be sufficient
income or proceeds from the Trust Property to enable the Property Trustee or
Paying Agent to make payments in accordance with the terms hereof.  Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the income and proceeds from the Trust Property to the extent
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security.  This
Section 8.01(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

         (c)  All duties and responsibilities of the Property Trustee contained
in this Trust Agreement are subject to the following:

              (i)  the Property Trustee's sole duty with respect to the
         custody, safe keeping and physical preservation of the Trust Property
         shall be to deal with such property in a similar manner as the
         Property Trustee deals with similar property for its own account,
         subject to the protections and limitations on liability afforded to
         the Property Trustee under this Trust Agreement, the Trust Indenture
         Act and, to the extent applicable, Rule 3a-7 under the Investment
         Company Act of 1940, as amended;

             (ii)  the Property Trustee shall have no duty or liability for or
         with respect to the value, genuineness, existence or sufficiency of
         the Trust Property or the payment of any taxes or assessments levied
         thereon or in connection therewith;


                                         -33-

<PAGE>

            (iii)  the Property Trustee shall not be liable for any interest on
         any money received by it except as it may otherwise agree with the
         Depositor.  Money held by the Property Trustee need not be segregated
         from other funds held by it except in relation to the Payment Account
         established by the Property Trustee pursuant to this Trust Agreement
         and except to the extent otherwise required by law; and

             (iv)  the Property Trustee shall not be responsible for monitoring
         the compliance by the Administrative Trustees or the Depositor with
         their respective duties under this Trust Agreement, nor shall the
         Property Trustee be liable for the default or misconduct of the
         Administrative Trustees or the Depositor.

         Section 8.02.  Notice of Defaults.  Within five Business Days after
the occurrence of any Event of Default, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.08, notice of any default
known to the Property Trustee to the Securityholders and the Depositor, unless
such default shall have been cured or waived.  For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

         Section 8.03.  Certain Rights of Property Trustee.  Subject to the
provisions of Section 8.01 and except as provided by law:

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

             (ii)  if (A) in performing its duties under this Trust Agreement
         the Property Trustee is required to decide between alternative courses
         of action or (B) in construing any of the provisions in this Trust
         Agreement the Property Trustee finds the same ambiguous or
         inconsistent with any other provisions contained herein or (C) the
         Property Trustee is unsure of the application of any provision of this
         Trust Agreement, then, except as to any matter as to which the
         Preferred Securityholders are entitled to vote under the terms of this
         Trust Agreement, the Property Trustee shall deliver a notice to the
         Depositor requesting written instructions of the Depositor as to the
         course of action to be taken.  The Property Trustee shall take such
         action, or refrain from taking such action, as the Property Trustee
         shall be instructed in writing to take, or to refrain from taking, by
         the Depositor; provided, however, that if the Property Trustee does
         not receive such instructions of the Depositor within ten Business
         Days after it


                                         -34-

<PAGE>

         has delivered such notice, or such reasonably shorter period of time
         set forth in such notice (which to the extent practicable shall not be
         less than two Business Days), it may, but shall be under no duty to,
         take or refrain from taking such action not inconsistent with this
         Trust Agreement as it shall deem advisable and in the best interests
         of the Securityholders, in which event the Property Trustee shall have
         no liability except for its own bad faith, negligence or willful
         misconduct;

            (iii)  whenever in the administration of this Trust Agreement the
         Property Trustee shall deem it desirable that a matter be proved or
         established prior to taking, suffering or omitting any action
         hereunder, the Property Trustee (unless other evidence be herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and rely upon an Officers' Certificate which, upon receipt of
         such request, shall be promptly delivered by the Depositor or the
         Administrative Trustees;

             (iv)  the Property Trustee may consult with counsel of its
         selection 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;

              (v)  the Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Trust
         Agreement at the request or direction of any of the Securityholders
         pursuant to this Trust Agreement, unless such Securityholders shall
         have offered to the Property Trustee reasonable security or indemnity
         against the costs, expenses (including reasonable attorneys' fees and
         expenses) and liabilities which might be incurred by it in complying
         with such request or direction;

             (vi)  the Property 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, bond, debenture, note or other
         evidence of indebtedness or other paper or document reasonably
         believed by it to be genuine, unless requested in writing to do so by
         one or more Securityholders, but the Property Trustee, in its
         discretion, may make such further inquiry or investigation into such
         facts or matters as it may see fit, and, if the Property Trustee shall
         determine to make such further inquiry or investigation, it shall be
         entitled to examine the books, records and premises of the Depositor
         personally or by agent or attorney; 

            (vii)  the Property Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through its agents or attorneys, and the Property Trustee shall not be
         responsible for any misconduct or negligence on the part of any agent
         or attorney appointed with


                                         -35-

<PAGE>

         due care by it hereunder, provided that the Property Trustee shall be
         responsible for its own negligence or recklessness with respect to
         selection of any agent or attorney appointed by it hereunder;

           (viii)  the Property Trustee shall not be liable for any action
         taken, suffered, or omitted to be taken by it in good faith and
         reasonably believed by it to be authorized or within the discretion or
         rights or powers conferred upon it by this Trust Agreement;

             (ix)  the Property Trustee shall not be charged with knowledge of
         any default or Event of Default with respect to the Trust Securities
         unless either (1) a Responsible Officer of the Property Trustee shall
         have actual knowledge of the default or Event of Default or (2)
         written notice of such default or Event of Default shall have been
         given to the Property Trustee by the Depositor, the Administrative
         Trustees or by any Holder of the Trust Securities;

              (x)  no provision of this Trust Agreement shall be deemed to
         impose any duty or obligation on the Property Trustee to perform any
         act or acts or exercise any right, power, duty or obligation conferred
         or imposed on it in any jurisdiction in which it shall be illegal, or
         in which the Property Trustee shall be unqualified or incompetent in
         accordance with applicable law, to perform any such act or acts or to
         exercise any such right, power, duty or obligation; and no permissive
         or discretionary power or authority available to the Property Trustee
         shall be construed to be a duty;

             (xi)  no provision of this Trust Agreement shall require the
         Property Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its duties
         or in the exercise of any of its rights or powers, if the Property
         Trustee shall have reasonable grounds for believing that the repayment
         of such funds or liability is not reasonably assured to it under the
         terms of this Trust Agreement or adequate indemnity against such risk
         or liability is not reasonably assured to it;

            (xii)  the Property Trustee shall have no duty to see to any
         recording, filing or registration of any instrument (including any
         financing or continuation statement or any tax or securities) (or any
         rerecording, refiling or registration thereof);

           (xiii)  the Property Trustee shall have the right at any time to
         seek instructions concerning the administration of this Trust
         Agreement from any court of competent jurisdiction; and

            (xiv)  whenever in the administration of this Trust Agreement the
         Property Trustee shall deem it desirable to receive instructions with
         respect to enforcing


                                         -36-

<PAGE>

         any remedy or right or taking any other action hereunder the Property
         Trustee (i) may request instructions from the Holders of the Trust
         Securities, which instructions may only be given by the Holders of the
         same proportion of Liquidation Amount of the Trust Securities as would
         be entitled to direct the Property Trustee under the terms of this
         Trust Agreement in respect of such remedies, rights or actions, (ii)
         may refrain from enforcing such remedy or right or taking such other
         action until such instructions are received, and (iii) shall be
         protected in acting in accordance with such instructions.

         Section 8.04.  Not Responsible for Recitals or Issuance of Securities. 
The recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust or the Depositor, and the Trustees do not
assume any responsibility for their correctness.  The Trustees make no
representations as to the value or condition of the property of the Trust or any
part thereof or as to the title of the Trust thereto or as to the security
afforded thereby or hereby, or as to the validity or genuineness of any
securities at any time pledged and deposited with any Trustees hereunder, nor as
to the validity or sufficiency of this Trust Agreement or the Trust Securities. 
The Trustees shall not be accountable for the use or application by the Trust of
the proceeds of the Trust Securities in accordance with Section 2.05.
   
         Section 8.05.  May Hold Securities.  Except as provided in the
definition of the term "Outstanding" in Article I, any Trustee or any other
agent of any Trustee or the Trust, in its individual or any other capacity, may

Trust with the same rights it would have if it were not a Trustee or such other
agent. 

         Section 8.06.  Compensation; Fees; Indemnity.

         The Depositor agrees 

         (1)  to pay to the Trustees from time to time reasonable compensation
    for all services rendered by the Trustees 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
    Trustees upon request for all reasonable expenses, disbursements and
    advances reasonably incurred or made by the Trustees in accordance with any
    provision of this Trust Agreement (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 (gross negligence, in the case of any Administrative Trustee),
    bad faith or willful misconduct; and

         (3)  to indemnify each Trustee, any Affiliate of any Trustee, and 
    any officer, director, shareholder or employee of any Trustee for, and to 
    hold each of them harmless against, any and all loss, damage, claims, 
    liability or expenses incurred without negligence


                                         -37-

<PAGE>

    (gross negligence, in the case of any Administrative Trustee), bad faith or
    willful misconduct on its part, arising out of or in connection with the
    acceptance or administration of this Trust Agreement, including the
    reasonable costs and expenses of defending itself against any claim or
    liability in connection with the exercise or performance of any of its
    powers or duties hereunder.

         As security for the performance of the obligations of the Depositor
under this Section, each of the Trustees shall have a lien prior to the Trust
Securities upon all property and funds held or collected by such Trustee as
such, except funds held in trust for the payment of Distributions on the Trust
Securities.

         The provisions of this Section shall survive the termination of this
Trust Agreement.

         Section 8.07.  Certain Trustees Required; Eligibility.  

         (a) There shall at all times be a Property Trustee hereunder with
respect to the Trust Securities.  The Property Trustee shall be a Person that
has a combined capital and surplus of at least $50,000,000.  If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person 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 Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VIII.

         (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities.  Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal

         (c) There shall at all times be a Delaware Trustee with respect to the
Trust Securities.  The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware that
otherwise meets the requirements of applicable Delaware law and that shall act
through one or more persons authorized to bind such entity.

         Section 8.08.  Conflicting Interests.

         If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.  The Subordinated Indenture and the Guarantee Agreement shall be
deemed to be specifically described in this Trust Agreement for the purposes of
clause (i) of the first proviso contained in Section 310(b) of the Trust
Indenture Act.

         Section 8.09.  Co-Trustees and Separate Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, at any time or times, for the purpose of meeting the legal
requirements of the Trust Indenture Act or of any jurisdiction in which any part
of the Trust Property may at the time be located, the Depositor and the Property
Trustee shall have power to appoint, and upon the written request of the
Property Trustee, the Depositor shall for such purpose join with the Property
Trustee in the execution, delivery, and performance of all instruments and
agreements necessary or proper to appoint, one or more Persons approved by the
Property Trustee either to act as co-trustee, jointly with the Property Trustee,
of all or any part of such Trust Property, or to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section.  If the Depositor does not join
in such appointment within 15 days after the receipt by it of a request so to
do, or in case an Event of Default under the Subordinated Indenture has occurred
and is continuing, the Property Trustee alone shall have power to make such
appointment.

         Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged, and delivered
by the Depositor.  

         Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms,
namely:  

         (1) The Trust Securities shall be executed and delivered and all
    rights, powers, duties, and obligations hereunder in respect of the custody
    of securities, cash and other personal property held by, or required to be
    deposited or pledged with, the Trustees designated for such purpose
    hereunder, shall be exercised, solely by such Trustees.

         (2) The rights, powers, duties, and obligations hereby conferred or
    imposed upon the Property Trustee in respect of any property covered by
    such appointment shall be conferred or imposed upon and exercised or
    performed by the Property Trustee or


                                         -39-

    by the Property Trustee and such co-trustee or separate trustee jointly, as
    shall be provided in the instrument appointing such co-trustee or separate
    trustee, except to the extent that under any law of any jurisdiction in
    which any particular act is to be performed, the Property Trustee shall be
    incompetent or unqualified to perform such act, in which event such rights,
    powers, duties, and obligations shall be exercised and performed by such
    co-trustee or separate trustee.

         (3) The Property Trustee at any time, by an instrument in writing
    executed by it, with the written concurrence of the Depositor, may accept
    the resignation of or remove any co-trustee or separate trustee appointed
    under this Section 8.09, and, in case an Event of Default under the
    Subordinated Indenture has occurred and is continuing, the Property Trustee
    shall have power to accept the resignation of, or remove, any such
    co-trustee or separate trustee without the concurrence of the Depositor. 
    Upon the written request of the Property Trustee, the Depositor shall join
    with the Property Trustee in the execution, delivery, and performance of
    all instruments and agreements necessary or proper to effectuate such
    resignation or removal.  A successor to any co-trustee or separate trustee
    so resigned or removed may be appointed in the manner provided in this
    Section.

         (4) No co-trustee or separate trustee hereunder shall be personally
    liable by reason of any act or omission of the Trustee, or any other such
    trustee hereunder. 

         (5) The Property Trustee shall not be liable by reason of any act of a
    co-trustee or separate trustee.

         (6) Any Act of Holders delivered to the Property Trustee shall be
    deemed to have been delivered to each such co-trustee and separate trustee.

         Section 8.10.  Resignation and Removal; Appointment of Successor.  No
resignation or removal of any Trustee (as the case may be, the "Relevant
Trustee") and no appointment of a successor Relevant Trustee pursuant to this
Article shall become effective until the acceptance of appointment by the
successor Relevant Trustee in accordance with the applicable requirements of
Section 8.11.

         The Relevant Trustee may resign at any time by giving written notice
thereof to the Common Securityholders.  If the instrument of acceptance by a
successor Relevant Trustee required by Section 8.11 shall not have been
delivered to the Relevant Trustee within 30 days after the giving of such notice
of resignation, the resigning Relevant Trustee may petition any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, the Relevant Trustee may be removed at any time by Act of the Common
Securityholder.  If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee may be removed at such time only by Act of the
Securityholders of a majority of the aggregate


                                         -40-

<PAGE>

Liquidation Amount of the Outstanding Preferred Securities, delivered to the
Property Trustee (in its individual capacity and on behalf of the Trust).

         If the Relevant Trustee shall resign, be removed or become incapable
of continuing to act as Relevant Trustee at a time when no Debenture Event of
Default shall have occurred and be continuing, the Common Securityholder, by Act
of the Common Securityholder delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and the retiring
Relevant Trustee shall comply with the applicable requirements of Section 8.11. 
If the Property Trustee shall resign, be removed or become incapable of
continuing to act as the Property Trustee at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Preferred Securityholders of a majority in Liquidation Amount of the
Outstanding Preferred Securities delivered to the retiring Property Trustee,
shall promptly appoint a successor Property Trustee, and such successor Property
Trustee shall comply with the applicable requirements of Section 8.11.  If no
successor Relevant Trustee shall have been so appointed by the Common
Securityholders or the Preferred Securityholders and accepted appointment in the
manner required by Section 8.11, any Securityholder who has been a
Securityholder for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

         The retiring Relevant Trustee shall give notice of each resignation
and each removal of the Relevant Trustee and each appointment of a successor
Trustee to the Common Securityholders in the manner provided in Section 10.08
and shall give notice to the Depositor.  Each notice shall include the name and
address of the successor Relevant Trustee and, in the case of the Property
Trustee, the address of its Corporate Trust Office.

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes incompetent or incapacitated, the vacancy
created by such death, incompetence or incapacity may be filled by (i) the
unanimous act of remaining Administrative Trustees if there are at least two of
them or (ii) otherwise by the Depositor (with the successor in each case being a
Person who satisfies the eligibility requirements for Administrative Trustees or
Delaware Trustee, as the case may be, set forth in Section 8.07).  Additionally,
notwithstanding the foregoing or any other provision of this Trust Agreement, in
the event the Depositor reasonably believes that any Administrative Trustee who
is a natural person has become incompetent or incapacitated, the Depositor, by
notice to the remaining Trustees, may terminate the status of such Person as an
Administrative Trustee (in which case the vacancy so created will be filled in
accordance with the preceding sentence).

         Section 8.11.  Acceptance of Appointment by Successor.   In case of
the appointment hereunder of a successor Relevant  Trustee, the retiring
Relevant Trustee and each successor Trustee  shall execute and deliver an
instrument wherein each successor Relevant Trustee shall accept such appointment
and which shall contain such provisions as shall be


                                         -41-

<PAGE>

necessary or desirable to transfer and confirm to, and to vest in, each
successor Relevant Trustee all the rights, powers, trusts and duties of the
retiring Relevant Trustee with respect to the Trust Securities and the Trust and
upon the execution and delivery of such instrument the resignation or removal of
the retiring Relevant Trustee shall become effective to the extent provided
therein and each such successor Relevant Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Relevant Trustee; but, on request of the Trust or any
successor Relevant Trustee such retiring Relevant Trustee shall duly assign,
transfer and deliver to such successor Trustee all Trust Property, all proceeds
thereof and money held by such retiring Relevant Trustee hereunder with respect
to the Trust Securities and the Trust.

         Upon request of any such successor Relevant Trustee, the retiring
Relevant Trustee shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Relevant Trustee all such
rights, powers and trusts referred to in the first or second preceding
paragraph, as the case may be.

         No successor Relevant Trustee shall accept its appointment unless at
the time of such acceptance such successor Relevant Trustee shall be qualified
and eligible under this Article VIII. 

         Section 8.12.  Merger, Conversion, Consolidation or Succession to
Business.  Any Person into which the Property Trustee or the Delaware Trustee or
any Administrative Trustee or any Trustee that is not a natural person may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided such Person shall be otherwise
qualified and eligible under this Article VIII, without the execution or filing
of any paper or any further act on the part of any of the parties hereto.

         Section 8.13.  Preferential Collection of Claims Against Depositor or
Trust.  If and when the Property Trustee shall be or become a creditor of the
Depositor or the Trust (or any other obligor upon the Debentures or the Trust
Securities), the Property Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Depositor or
Trust (or any such other obligor).

         Section 8.14.  Reports by Property Trustee. 

         (a) the Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.  Such of those reports as are
required to be transmitted by the Property Trustee pursuant to Section 313(a) of
the Trust Indenture Act shall be so transmitted within 60 days after _______ of
each year, commencing ____________, 1997.


                                         -42-

<PAGE>

         (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Property Trustee with each stock exchange upon which
the Trust Securities are listed, with the Commission and with the Depositor. 
The Depositor will notify the Property Trustee when any Trust Securities are
listed on any stock exchange.

         Section 8.15.  Reports to the Property Trustee.  The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information as required by Section 314 (if
any) and the compliance certificate required by Section 314 of the Trust
Indenture Act in the form, in the manner and at the times required by Section
314 of the Trust Indenture Act.

         Section 8.16.  Evidence of Compliance with Conditions Precedent.  Each
of the Depositor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such evidence of compliance with any conditions
precedent, if any, provided for in this Trust Agreement (including any covenants
compliance with which constitutes a condition precedent) that relate to any of
the matters set forth in Section 314(c) of the Trust Indenture Act.  Any
certificate or opinion required to be given by an officer pursuant to Section
314(c)(1) of the Trust Indenture Act may be given in the form of an Officers'
Certificate.

         Section 8.17.  Number of Trustees.

         (a) The number of Trustees shall be five, provided that Depositor, by
written instrument may increase or decrease the number of Administrative
Trustees.   

         (b) If a Trustee ceases to hold office for any reason and the number
of Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the
number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur.  The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust.  Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 8.10, the Administrative
Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Trust Agreement.

         Section 8.18.  Delegation of Power.

         (a) Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.07(a), including any registration statement or amendment thereto filed with
the Commission, or making any other governmental filing; and

         (b) the Administrative Trustees shall have power to delegate from time
to time to such of their number the doing of such things and the execution of
such instruments either in the name of the Trust or the names of the
Administrative Trustees or otherwise as the Administrative Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of the Trust, as set forth herein. 

         Section 8.19.  Fiduciary Duty.

         (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Trust Agreement shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Trust Agreement.  The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person;

         (b) Unless otherwise expressly provided herein and subject to the
provisions of the Trust Indenture Act:

              (i)  whenever a conflict of interest exists or arises between an
         Indemnified Person and any Covered Person; or

             (ii)  whenever this Trust Agreement or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Trust Securities, the  
         Indemnified Person shall resolve such conflict of interest, take such
         action or provide such terms, considering in each case the relative
         interest of each party (including its own interest) to such conflict,
         agreement, transaction or situation and the benefits and burdens
         relating to such interests, any customary or accepted industry
         practices, and any applicable generally accepted accounting practices
         or principles.  In the absence of bad faith by the Indemnified Person,
         the resolution, action or term so made, taken or provided by the
         Indemnified Person shall not constitute a breach of this Trust
         Agreement or any other agreement contemplated herein or of any duty or
         obligation of the Indemnified Person at law or in equity or otherwise;
         and

<PAGE>

         (c) Unless otherwise expressly provided herein and subject to the
provisions of the Trust Indenture Act, whenever in this Trust Agreement an
Indemnified Person is permitted or required to make a decision

              (i)  in its "discretion" or under a grant of similar authority,
         the Indemnified Person shall be entitled to consider such interests
         and factors as it reasonably desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

              (ii) in its "good faith" or under another express standard, the
         Indemnified Person shall act under such express standard and shall not
         be subject to any other or different standard imposed by this Trust
         Agreement or by applicable law.

         Section 8.20   Outside Business.  The Depositor and any Trustee may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the business
of the Trust, and the Trust and the Holders of Trust Securities shall have no
rights by virtue of this Trust Agreement in and to such independent ventures or
the income or profits derived therefrom, and the pursuit of any such venture,
even if competitive with the business of the Trust, shall not be deemed wrongful
or improper.  Neither the Depositor, nor any Trustee, shall be obligated to
present any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the Trust, and the Depositor or any Trustee shall have the right to take for its
own account (individually or as a partner or fiduciary) or to recommend to
others any such particular investment or other opportunity.  Any Trustee may
engage or be interested in any financial or other transaction with the Depositor
or any Affiliate of the Depositor, or may act as depository for, trustee or
agent for, or act on any committee or body of holders of, securities or other
obligations of the Depositor or its Affiliates.

                                         -45-

<PAGE>

             (ii)  the redemption of all of the Preferred Securities;

            (iii)  delivery of written direction to the Property Trustee by the
         Depositor at any time (which direction is wholly optional and within
         the discretion of the Depositor) to dissolve the Trust and distribute
         the Debentures to Securityholders in accordance with Section 9.04;

             (iv)  an order for judicial dissolution of the Trust having been
         entered by a court of competent jurisdiction;

the Trust shall dissolve and the Trustees shall take such action as is required
by Section 9.04.

         Section 9.03.  Termination.  The respective obligations and
responsibilities of the Trustees and the Trust created hereby shall terminate
upon the latest to occur of the following: (i) the distribution by the Property
Trustee to Securityholders upon the liquidation of the Trust pursuant to Section
9.04, or upon the redemption of all of the Trust Securities pursuant to Section
4.02, of all amounts required to be distributed hereunder upon the final payment
of the Trust Securities; (ii) the payment or provision for payment of any
expenses owed by the Trust; (iii) the discharge of all administrative duties of
the Administrative Trustees, including the performance of any tax reporting
obligations with respect to the Trust or the Securityholders and (iv) the filing
of a certificate of cancellation under the Delaware Business Trust Act.

         Section 9.04.  Liquidation.  (a)   Upon the occurrence of the
Expiration Date or an Early Termination Event specified in clause (i), (iii) or
(iv) of Section 9.02, after satisfaction of creditors of the Trust, if any, as
provided by applicable law, the Trust shall be liquidated by the Property
Trustee as expeditiously as the Property Trustee determines to be appropriate by
distributing to each Securityholder a Like Amount of Debentures, subject to
Section 9.04(d).  Notice of liquidation shall be given by the Administrative
Trustees by first-class mail, postage prepaid, mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register.  All notices of
liquidation shall:

              (i)  state the Liquidation Date;

             (ii)  state that from and after the Liquidation Date, the Trust
         Securities will no longer be deemed to be outstanding and any Trust
         Securities Certificates not surrendered for exchange will be deemed to
         represent a Like Amount of Debentures; and

            (iii)  provide such information with respect to the mechanics by
         which Holders may exchange Trust Securities Certificates for
         Debentures, or if Section 9.04(d) applies, receive a Liquidation
         Distribution, as the Administrative Trustees or the Property Trustee
         shall deem appropriate.


                                         -46-

<PAGE>

         (b) Except where Section 9.02(ii) or 9.04(d) applies, in order to
effect the liquidation of the Trust, if any, and distribution of the Debentures
to Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 9.02(ii) or 9.04(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates (or, at the election of the Depositor, a Global
Debenture, subject to the provisions of the Indenture) representing a Like
Amount of Debentures will be issued to Holders of Trust Securities Certificates,
upon surrender of such Trust Securities Certificates to the Administrative
Trustees or their agent for exchange, (iii) the Depositor shall use its
reasonable efforts to have the Debentures listed on the New York Stock Exchange
or on such other securities exchange or other organization as the Preferred
Securities are then listed or traded, (iv) any Trust Securities Certificates not
so surrendered for exchange will be deemed to represent a Like Amount of
Debentures, accruing interest at the rate provided for in the Debentures from
the last Distribution Date on which a Distribution was made on such Trust
Certificates until such Trust Securities Certificates are so surrendered (and
until such Trust Securities Certificates are so surrendered, no payments or
interest or principal will be made to Holders of Trust Securities Certificates
with respect to such Debentures) and (v) all rights of Securityholders holding
Trust Securities will cease, except the right of such Securityholders to receive
Debentures upon surrender of Trust Securities Certificates.
  
         (d) In the event that, notwithstanding the other provisions of this
Section 9.04, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as the
Property Trustee determines.  In such event, on the date of the dissolution,
winding-up or other termination of the Trust, Securityholders will be entitled
to receive out of the assets of the Trust available for distribution to
Securityholders, after satisfaction of liabilities to creditors of the Trust, if
any, as provided by applicable law, an amount equal to the Liquidation Amount
per Trust Security plus accumulated and unpaid Distributions thereon to the date
of payment (such amount being the "Liquidation Distribution").  If, upon any
such dissolution, winding up or termination, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then, subject to the next
succeeding sentence, the amounts payable by the Trust on the Trust Securities
shall be paid on a pro rata basis (based upon Liquidation Amounts).  The Holder
of Common Securities will be entitled to receive Liquidation Distributions upon
any such dissolution, winding-up or termination pro rata (determined as
aforesaid) with Holders of Preferred Securities, except that, if a Debenture
Event of Default has occurred and is continuing or if a Debenture Event of
Default has not occurred solely by reason of a requirement that time lapse


                                         -47-

or notice be given, the Preferred Securities shall have a priority over the
Common Securities.     

                                      ARTICLE X.

                               Miscellaneous Provisions

         Section 10.01.  Guarantee by the Depositor and Assumption of
Obligations.  Subject to the terms and conditions hereof, the Depositor
irrevocably and unconditionally guarantees to each Person to whom the Trust is
now or hereafter becomes indebted or liable (the "Beneficiaries"), and agrees to
assume liability for, the full payment, when and as due, of any and all
Obligations (as hereinafter defined) to such Beneficiaries.  As used herein,
"Obligations" means any indebtedness, expenses or liabilities of the Trust,
other than obligations of the Trust to pay to Holders or other similar interests
in the Trust the amounts due such Holders pursuant to the terms of the Preferred
Securities or such other similar interests, as the case may be.  This guarantee
and assumption is intended to be for the benefit, of, and to be enforceable by,
all such Beneficiaries, whether or not such Beneficiaries have received notice
hereof.

         Section 10.02.  Limitation of Rights of Securityholders.  The death or
incapacity of any person having an interest, beneficial or otherwise, in a Trust
Security shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of such person or any Securityholder for such
person, to claim an accounting, take any action or bring any proceeding in any
court for a partition or winding up of the arrangements contemplated hereby, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

         Section 10.03.  Amendment.

         (a) This Trust Agreement may be amended from time to time by the Trust
(on approval of a majority of the Administrative Trustees and the Depositor,
without the consent of any Securityholders), (i) to cure any ambiguity, correct
or supplement any provision herein or therein which may be inconsistent with any
other provision herein or therein, or to make any other provisions with respect
to matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement or (ii) to
modify, eliminate or add to any provisions of this Trust Agreement to such
extent as shall be necessary to ensure that the Trust will not be classified for
United States federal income tax purposes other than as a "grantor trust" and
not as an association taxable as a corporation at any time that any Trust
Securities are outstanding or to ensure the Trust's exemption from the status of
an "investment company" under the Investment Company Act of 1940, as amended;
provided, however, that, except in the case of clause (ii), such action shall
not adversely affect in any material respect the interests of any Securityholder
and, in the case of clause (i), any amendments of this Trust Agreement shall
become effective when notice thereof is given to the Securityholders.


                                         -48-

<PAGE>

         (b) Except as provided in Sections 6.01(c) and 10.03(c), any provision
of this Trust Agreement may be amended by the Administrative Trustees and the
Depositor with (i) the consent of Holders of Trust Securities representing not
less than a majority (based upon Liquidation Amounts) of the Outstanding Trust
Securities and (ii) receipt by the Trustees of an Opinion of Counsel to the
effect that such amendment or the exercise of any power granted to the Trustees
in accordance with such amendment will not affect the Trust's status as a
grantor trust for federal income tax purposes or the Trust's exemption from
status of an "investment company" under the Investment Company Act of 1940, as
amended. 

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.03 or 6.06), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date.

         (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an "investment company" under the Investment Company Act of 1940, as
amended, afforded by Rule 3a-5 thereunder.

         (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor and the Trustees, this Trust Agreement may
not be amended in a manner which imposes any additional obligation on the
Depositor or any Trustee. 

         (f) In the event that any amendment to this Trust Agreement is made,
the Administrative Trustees shall promptly provide to the Depositor a copy of
such amendment.  

         (g) The Property Trustee is entitled to receive an Opinion of Counsel
as conclusive evidence that any amendment to this Trust Agreement executed
pursuant to this Section 10.03 is authorized or permitted by, and conforms to,
the terms of this Section 10.03, has been duly authorized by and lawfully
executed and delivered on behalf of the other requisite parties, and that it is

any provision of this Indenture, the Company shall, if requested by the Trustee,
furnish to the Trustee an Officer's Certificate stating that all conditions
precedent, if any, provided for in this Indenture relating to the proposed
action (including any covenants compliance with which constitutes a condition
precedent) have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent, if any, have been
complied with, except that in the case of any such application or request as to
which the furnishing of such documents is specifically required by any provision
of this Indenture relating to such particular application or request, no
additional certificate or opinion need be furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

         (a)  a statement that each Person signing such certificate or
    opinion has read such covenant or condition and the definitions herein

    Person has made such examination or investigation as is necessary to
    enable such Person to express an informed opinion as to whether or not

SECTION 103.  Form of Documents Delivered to Trustee.

Person, or that they be so certified or covered by only


                                         -8-
<PAGE>

one document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such Officer's Certificate or opinion are
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
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other

form one instrument.

         Whenever, subsequent to the receipt by the Trustee of any Board
Resolution, Officer's Certificate, Opinion of Counsel or other document or
instrument, a clerical, typographical or other inadvertent or unintentional
error or omission shall be discovered therein, a new document or instrument may
be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted.  Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Company which could not have been taken had the
original document or instrument not contained such error or omission, the action
so taken shall not be invalidated or otherwise rendered ineffective but shall be
and remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith.  Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Company entitled to the benefits of this Indenture equally and ratably with all
other Outstanding Securities, except as aforesaid.

SECTION 104.  Acts of Holders.

         (a)  Any request, demand, authorization, direction, notice, consent,
    election, waiver or other action provided by this Indenture to be made,
    given or taken by Holders may be embodied in and evidenced by one or more
    instruments of substantially similar

                                         -9-
<PAGE>

tenor signed by such Holders in person or by an agent duly appointed in writing
or, alternatively, may be embodied in and evidenced by the record of Holders
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders duly called and held in accordance with the
provisions of Article Thirteen, or a combination of such instruments and any
such record.  Except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments or record or both are
delivered to the Trustee and, where it is hereby expressly required, to the
Company.  Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments and so voting at any
such meeting.  Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to section 901)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.  The record of any meeting of Holders shall be proved
in the manner provided in Section 1306.

         (b)  The fact and date of the execution by any Person of any such
    instrument or writing may be proved by the affidavit of a witness of such
    execution or by a certificate of a notary public or other officer
    authorized by law to take acknowledgments of deeds, certifying that the
    individual signing such instrument or writing acknowledged to him the
    execution thereof or may be proved in any other manner which the Trustee
    and the Company deem sufficient.  Where such execution is by a signer
    acting in a capacity other than his individual capacity, such certificate
    or affidavit shall also constitute sufficient proof of his authority.

         (c)  The principal amount and serial numbers of Securities held by any
    Person, and the date of holding the same, shall be proved by the Security
    Register.

         (d)  Any request, demand, authorization, direction, notice,
    consent, election, waiver or other Act of a Holder shall bind every
    future Holder of the same Security and the Holder of every Security
    issued upon the registration of transfer thereof or in exchange
    therefor or in lieu thereof in respect of anything done, omitted or
    suffered to be done by the Trustee or the Company in reliance thereon,
    whether or not notation of such action is made upon such Security.

         (e)  Until such time as written instruments shall have been
    delivered to the Trustee with respect to the requisite percentage of
    principal amount of Securities for the action contemplated by such
    instruments, any such instrument executed and delivered by or on
    behalf of a Holder may be revoked with respect to any or all of such
    Securities by written notice by such Holder or any subsequent Holder,
    proven in the manner in which such instrument was proven.


                                         -10-

         (f)  Securities of any series authenticated and delivered after
    any Act of Holders may, and shall if required by the Trustee, bear a
    notation in form approved by the Trustee as to any action taken by
    such Act of Holders.  If the Company shall so determine, new
    Securities of any series so modified as to conform, in the opinion of
    the Trustee and the Company, to such action may be prepared and
    executed by the Company and authenticated and delivered by the Trustee
    in exchange for Outstanding Securities of such series.

         (g)  If the Company shall solicit from Holders any request,
    demand, authorization, direction, notice, consent, waiver or other
    Act, the Company may, at its option, fix in advance a record date for
    the determination of Holders 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 such record
    date, but only the Holders of record at the close of business on the
    record date shall be deemed to be Holders for the purposes of
    determining whether Holders of the requisite proportion of the
    Outstanding Securities have authorized or agreed or consented to such
    request, demand, authorization, direction, notice, consent, waiver or
    other Act, and for that purpose the Outstanding Securities shall be
    computed as of the record date.

SECTION 105.  Notices, etc. to Trustee and Company.

    Any request, demand, authorization, direction, notice, consent, election,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with, the Trustee by
any Holder or by the Company, or the Company by the Trustee or by any Holder,
shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and delivered personally to an officer or
other responsible employee of the addressee, or transmitted by facsimile
transmission or other direct written electronic means to such telephone number
or other electronic communications address as the parties hereto shall from time
to time designate, or transmitted by certified or registered mail, charges
prepaid, to the applicable address set opposite such party's name below or to

of receipt.

SECTION 106.  Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given, and shall be deemed given, to Holders if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Security Register, not later than
the latest date, if any, and not earlier than the earliest date, if any,
prescribed for the giving of such notice.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
Holders by mail, then such notification as shall be made with the approval of
the Trustee shall constitute a sufficient notification for every purpose
hereunder.  In any case, where notice to Holders is given by mail. neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.

         Any notice required by this Indenture may be waived in writing by the
Person entitled to receive such notice, either before or after the event
otherwise to specified therein, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

SECTION 107.  Conflict with Trust Indenture Act.

         If any provision of this Indenture limits, qualifies or conflicts with
another provision hereof which is required or deemed to be included in this
Indenture by, or is otherwise

<PAGE>

governed by, any of the provisions of the Trust Indenture Act, such other
provision shall control; and if any provision hereof otherwise conflicts with
the Trust Indenture Act, the Trust Indenture Act shall control.

SECTION 108.  Effect of Headings and Table of Contents.

         The Article and Section headings in this Indenture and the Table of
Contents are for convenience only and shall not affect the construction hereof.

SECTION 109.  Successors and Assigns.

         All covenants and agreements in this Indenture by the Company and
Trustee shall bind their respective successors and assigns, whether so expressed
or not.

SECTION 110.  Separability Clause.

         In case any provision in this Indenture or the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111.  Benefits of Indenture.

         Nothing in this Indenture or the Securities, express or implied, shall
give to any Person, other than the parties hereto, their successors hereunder,
the Holders and, so long as the notice described in Section 1513 hereof has not
been given, the holders of Senior Indebtedness, any benefit or any legal or
equitable right, remedy or claim under this Indenture; provided, however, if the
Property Trustee fails to enforce its rights with respect to the Securities or
the related Trust Agreement, a holder of Preferred Securities may institute a
legal proceeding directly against the company to enforce the Property Trustee's
rights with respect to the Securities or such Trust Agreement, to the fullest
extent permitted by law, without first instituting any legal proceeding against
the Property Trustee or any other person or entity.

         This Indenture and the Securities shall be governed by and construed
in accordance with the laws of the State of New York, except to the extent that
the law of any other jurisdiction shall be mandatorily applicable.

SECTION 113.  Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any


                                         -13-
<PAGE>

other provision of this Indenture or of the Securities other than a provision in
Securities of any series, or in the Board Resolution or Officer's Certificate
which establishes the terms of the Securities of such series, which specifically
states that such provision shall apply in lieu of this Section) payment of
interest or principal and premium, if any, need not be made at such Place of
Payment on such date, but may be made on the next Succeeding Business Day at
such Place of Payment, except that if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect, and in the
same amount, as if made on the Interest Payment Date or Redemption Date, or at
the Stated Maturity, as the case may be, and, if such payment is made or duly
provided for on such Business Day, no interest shall accrue on the amount so
payable for the period from and after such interest Payment Date, Redemption
Date or Stated Maturity, as the case may be, to such Business Day.

          such enforceability is considered in a proceeding in equity or at 
          law).

         If the form or terms of the Securities of any series have been
established by or pursuant to a Board Resolution or an  Officer's Certificate as
permitted by Section 201 or 301, the Trustee shall not be required to
authenticate such Securities if the issuance of such securities pursuant to this
Indenture will materially or adversely affect the Trustee's own rights, duties
or immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, each Security shall be dated the date of its
authentication.

         Unless otherwise specified as contemplated by Section 301 with respect
to any series of Securities, no Security shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on
such Security a certificate of authentication substantially in the form provided
for herein executed by the Trustee or an Authenticating Agent by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder to the Company, or any Person acting on its behalf, but
shall never have been issued and sold by the Company, and the Company shall
deliver such


                                         -20-
<PAGE>

Security to the Trustee for cancellation as provided in Section 309 together
with a written statement which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been
issued and sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits hereof.

SECTION 304.  Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company order the Trustee shall authenticate and
deliver, temporary Securities, which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as evidenced
by their execution of such Securities; provided, however, that temporary
Securities need not recite specific redemption, sinking fund, conversion or
exchange provisions.

         Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, after the preparation of definitive Securities
of such series the temporary Securities of such series shall be exchangeable,
without charge to the Holder thereof, for definitive Securities of such series
upon surrender of such temporary Securities at the office or agency of the
Company maintained pursuant to Section 602 in a Place of Payment for such
Securities.  Upon such surrender of temporary securities for such exchange, the
Company shall, except as aforesaid, execute and the Trustee shall authenticate
and deliver in exchange therefor definitive Securities of the same series, of
authorized denominations and of like tenor and aggregate principal amount.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities or the same series and or like
tenor authenticated and delivered hereunder.

SECTION 305.  Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept in each office designated pursuant
to Section 602, with respect to the Securities of each series, a register (all
registers kept in accordance with this Section being collectively referred to as
the "Security Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities of
such series and the registration of transfer thereof.  The Company shall
designate one Person to maintain the Security Register for the Securities of
each series on a consolidated basis and such Person is referred to herein, with
respect to such series, as the "Security Registrar." Anything herein to the
contrary notwithstanding, the Company may designate one or more of its offices
as an office in which a register with respect to the Securities of one
or more series shall be maintained, and the Company may designate itself the
Security Registrar with respect to one 


                                         -21-
<PAGE>

or more of such series.  The Security Register shall be open for inspection 
by the Trustee and the Company at all reasonable times.

         Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, upon surrender for registration of
transfer of any Security of such series at the office or agency of the Company
maintained pursuant to Section 602 in a Place of Payment for such series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of authorized denominations and of like tenor and aggregate
principal amount.

         Except as otherwise specified as contemplated by Section 301 with
respect to the Securities of any series, any Security of such series may be
exchanged at the option of the Holder, for one or more new Securities of the
same series, of authorized denominations and of like tenor and aggregate
principal amount, upon surrender of the Securities to be exchanged at any such
office or agency.  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

         All Securities delivered upon any registration of transfer or exchange
of Securities shall be valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company, the Trustee or the
Security Registrar) be duly endorsed or shall be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee or the
Security Registrar, as the case may be, duly executed by the Holder thereof or
his  attorney duly authorized in writing.

         Unless otherwise specified as contemplated by Section 301 with respect
to Securities of any series, no service charge shall be made for any
registration of transfer or exchange of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 406 or 1206 not
involving any transfer.

         The Company shall not be required to execute or to provide for the
registration of transfer of or the exchange of (a) Securities of any series
during a period of 15 days immediately preceding the date of the mailing of any
notice of redemption of such Securities called for redemption or (b) any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series, and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the ownership of and the destruction, loss or
theft of any Security and (b) such security or indemnity as may be reasonably
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such Security
is held by a Person purporting to be the owner of such security, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same series, and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

         Notwithstanding the foregoing, in case any such mutilated, destroyed,
lost or stolen Security has become or is about to become due and payable, the
Company in its discretion may, instead of issuing a new Security, pay such
Security.

         Upon the issuance of any new Security under this Section, 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
reasonable expenses (including the fees and expenses of the Trustee) connected
therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone other than
the Holder of such new Security, and any such new Security shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities of such series duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

         Unless otherwise specified as contemplated by Section 301 with respect
to the Securities of any series, interest on any Security which is payable, and
is punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that



                                         -23-
<PAGE>

Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

         Subject to Section 311, any interest on any Security of any series
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease
to be payable to the Holder on the related Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the Company,
at its election in each case, as provided in clause (a) or (b) below:

         a)   The Company may elect to make payment of any Defaulted Interest
    to the Persons in whose names the Securities of such series (or their
    respective Predecessor Securities) are registered at the close of business
    on a date (herein called a "Special Record Date") for the payment of such
    Defaulted Interest, which shall be fixed in the following manner.  The
    Company shall notify the Trustee in writing of the amount of Defaulted
    Interest proposed to be paid on each Security of such series and the date
    of the proposed payment, and at the same time the Company shall deposit
    with the Trustee an amount of money equal to the aggregate amount proposed
    to be paid in respect of such Defaulted Interest or shall make arrangements
    satisfactory to the Trustee for such deposit on or prior to the date of the
    proposed payment, such money when deposited to be held in trust for the
    benefit of the Persons entitled to such Defaulted Interest as in this
    clause provided.  Thereupon the Trustee shall fix a Special Record Date for
    the Payment of such Defaulted interest which shall be not more than 15 days
    and not less than 10 days prior to the date of the proposed payment and not
    less than 10 days after the receipt by the Trustee of the notice of the
    proposed payment.  The Trustee shall promptly notify the Company of such
    Special Record Date and, in the name and at the expense of the Company,
    shall promptly cause notice of the proposed payment of such Defaulted
    Interest and the Special Record Date therefor to be mailed, first-class
    postage prepaid, to each Holder of Securities of such series; at the
    address of such Holder as it appears in the Security Register, not less
    then 10 days prior to such Special Record Date.  Notice of the proposed
    payment of such Defaulted interest and the Special Record Date therefor
    having been so mailed, such Defaulted Interest shall be paid to the Persons
    in whose names the Securities of such series (or their respective
    Predecessor Securities) are registered at the close of business on such
    Special Record Date.

         b)   The Company may make payment of any Defaulted Interest on the
    Securities of any series in any other lawful manner not inconsistent with
    the requirements of any securities exchange on which such Securities may be
    listed, and upon such notice as may be required by such exchange,  if,
    after notice given by the Company to the Trustee of the proposed payment
    pursuant to this clause, such manner of payment shall be deemed practicable
    by the Trustee.


                                         -24-
<PAGE>

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
security.

SECTION 308.  Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such security is registered as the absolute owner of
such Security for the purpose of receiving payment of principal of and premium,
if any, and (subject to Sections 305 and 307) interest, if any, on such Security
and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

SECTION 309.  Cancellation by Security Registrar.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Security
Registrar, be delivered to the Security Registrar and, if not theretofore
canceled, shall be promptly canceled by the Security Registrar.  The Company may
at any time deliver to the Security Registrar for cancellation any securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever or which the Company shall not have issued and
sold, and all Securities so delivered shall be promptly canceled by the Security
Registrar.  No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture.  All canceled securities held by the Security
Registrar shall be disposed of in accordance with a Company Order delivered to
the Security Registrar and the Trustee, and the Security Registrar shall
promptly deliver a certificate of disposition to the Trustee and the Company
unless, by a Company Order, similarly delivered, the Company shall direct that
canceled Securities be returned to it.  The Security Registrar shall promptly
deliver evidence of any cancellation of a Security in accordance with this
Section 309 to the Trustee and the Company.

SECTION 310.  Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year consisting of twelve 30-day months and
for any period shorter than a full month, on the basis of the actual number of
days elapsed in such period.

SECTION 311.  Extension of Interest Payment.


                                         -25-
<PAGE>

         The Company shall have the right at any time, so long as the Company
is not in default in the payment of interest on the Securities of any series
hereunder, to extend interest payment periods on all Securities of one or more
series, if so specified as contemplated by Section 301 with respect to such
Securities and upon such terms as may be specified as contemplated by Section
301 with respect to such Securities.

SECTION 312.  Additional Interest Attributable to Taxes.

         So long as any Preferred Securities remain outstanding, if the Trust
which issued such Preferred Securities shall be required to pay, with respect to
its income derived from the interest payments on the Securities of any series,
any amounts for or on account of any taxes, duties, assessments or governmental
charges of whatever nature imposed by the United States, or any other taxing
authority, then, in any such case, the Company will pay as interest on such
series such additional interest ("Additional Interest Attributable to Taxes") as
may be necessary in order that the net amounts received and retained by such
Trust after the payment of such taxes, duties, assessments or governmental
charges shall result in such Trust's having such funds as it would have had in
the absence of the payment of such taxes, duties, assessments or governmental
charges.

SECTION 313.  Agreed Tax Treatment.

         Each Security issued hereunder shall provide that the Company and, 
by its acceptance of a Security or a beneficial interest therein, the Holder 
of, and any Person that acquires a beneficial interest in, such Security 
agree that for United States federal, state and local tax purposes it is 
intended that such Security constitute indebtedness and agree to treat such 
security accordingly for such purposes.

SECTION 314.  Extension of Maturity Date; Adjustment of
             Maturity Date Upon an Exchange.

         If specified as contemplated by Section 301 with respect to the
Securities of a particular series, the Company shall have the right to (a)
change the Maturity Date of the Securities of such series upon the liquidation
of the corresponding Trust and the exchange of such Securities for the Preferred
Securities of such Trust and (b) extend the Maturity Date for the Securities of
such series at any time and from time to time; PROVIDED, that at the time any
election to extend the Maturity Date is made and at the time of such extension
(i) the Company is not in bankruptcy, otherwise insolvent or in liquidation,
(ii) the Company is not in default in the payment of any interest or principal
on the Securities of such series and no deferred interest payments thereon have
accrued, (iii) such Trust is not in arrears in payments of Distributions on its
Preferred Securities and no deferred Distributions thereon are accumulated, (iv)
the Securities are rated not less than BBB - by Standard & Poor's Ratings
Services or Baa3 by Moody's Investors Service, Inc. or the equivalent by any
other nationally recognized statistical rating organization and (v) the extended
Maturity Date is no later than the 49th anniversary of the initial


                                         -26-
<PAGE>

issuance of the Preferred Securities of such Trust; and PROVIDED, FURTHER, that,
if the Company exercises its rights to liquidate a Trust and exchange the
Securities of such series for the Preferred Securities of such Trust as
specified in clause (a) above, any changed Maturity Date of the Securities of
such series shall be (A) no earlier than the date five years after the initial
issuance of the Preferred Securities of such Trust and (B) no later than the
date 30 years (plus an extended term of up to an additional 19 years if the

                                  ARTICLE FOUR

                            Redemption of Securities

SECTION 401.  Applicability of Article.

          Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of such
series) in accordance with this Article.

SECTION 402.  Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or an Officer's Certificate.  The Company shall,
at least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of such Securities
to be redeemed.  In the case of any redemption of Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (b) pursuant to an election of the
Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officer's Certificate
evidencing compliance with such restriction or condition.

SECTION 403.  Selection of Securities to Be Redeemed.

          If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected by the Trustee from the
Outstanding Securities of such series not previously called for redemption, by
such method as shall be provided for any particular series, or, in the absence
of any such provision, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of such series or
any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of such series; provided, however, that if, as indicated in an
Officer's Certificate, the Company shall have offered to purchase all or any
principal amount of the Securities then Outstanding of any series and less than
all of such Securities as to which


                                      -27-
<PAGE>

such offer was made shall have been tendered to the Company for such purchase
the Trustee, if so directed by Company order, shall select for redemption all or
any principal amount of such Securities which have not been so tendered.

          The Trustee shall promptly notify the Company and the Security
Registrar in writing of the securities selected for redemption and, in the case
of any Securities selected to be redeemed in part, the principal amount thereof
to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such securities which has been or is to be
redeemed.

SECTION 404.  Notice of Redemption.

          Notice of redemption shall be given in the manner provided in Section
106 to the Holders of the Securities to be redeemed not less than 30 nor more
than 60 days prior to the Redemption Date.

          All notices of redemption shall state:

          a)   the Redemption Date,

          b)   the Redemption Price,

          c)   if less than all the Securities of any series are to be redeemed,
     the identification of the particular Securities to be redeemed and the
     portion of the principal amount of any Security to be redeemed in part,

          d)   that on the Redemption Date the Redemption Price, together with
     accrued interest, if any, to the Redemption Date, will become due and
     payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          e)   the place or places where such Securities are to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required,

          f)   that the redemption is for a sinking or other fund, if such is
     the case, and

          g)   such other matters as the Company shall deem desirable or
     appropriate.


                                      -28-
<PAGE>

          Unless otherwise specified with respect to any Securities in
accordance with Section 301, with respect to any notice of redemption of
Securities at the election of the Company, unless, upon the giving of such
notice, such Securities shall be deemed to have been paid in accordance with
Section 701, such notice may state that such redemption shall be conditional
upon the receipt by the Paying Agent or Agents for such Securities, on or prior
to the date fixed for such redemption, of money sufficient to pay the principal
of and premium, if any, and interest, if any, on such Securities and that if
such money shall not have been so received such notice shall be of no force or
effect and the Company shall not be required to redeem such Securities.  In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Paying Agent or Agents for the Securities
otherwise to have been redeemed shall promptly return to the Holders thereof any
of such Securities which had been surrendered for payment upon such redemption.

          Notice of redemption of Securities to be redeemed at the election of
the Company, and any notice of non-satisfaction of a condition for redemption as
aforesaid, shall be given by the Company or, at the Company's request, by the
Security Registrar in the name and at the expense of the Company.  Notice of
mandatory redemption of Securities shall be given by the Security Registrar in
the name and at the expense of the Company.

SECTION 405.  Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, and the
conditions, if any, set forth in such notice having been satisfied, the
Securities or portions thereof so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified, and from and
after such date (unless, in the case of an unconditional notice of redemption,
the Company shall default in the payment of the Redemption Price and accrued
interest, if any) such Securities or portions thereof, if interest-bearing,
shall cease to bear interest.  Upon surrender of any such Security for
redemption in accordance with such notice, such Security or portion thereof
shall be paid by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided, however, that no such
surrender shall be a condition to such payment if so specified as contemplated
by Section 301 with respect to such Security; and provided, further, that except
as otherwise specified as contemplated by Section 301 with respect to such
Security, any installment of interest on any Security the Stated Maturity of
which installment is on or prior to the Redemption Date shall be payable to the
Holder of such Security, or one or more Predecessor Securities, registered as
such at the close of business on the related Regular Record Date according to
the terms of such Security and subject to the provisions of Section 307.

SECTION 406.  Securities Redeemed in Part.


                                      -29-
<PAGE>

          Upon the surrender of any Security which is to be redeemed only in
part at a Place of Payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge, a new Security or securities of the same series, of any
authorized denomination requested by such Holder and of like tenor and in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                  ARTICLE FIVE

                                  Sinking Funds

SECTION 501.  Applicability of Article.

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of the Securities of any series, except as otherwise
specified as contemplated by Section 301 for Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 502.  Each sinking fund payment shall be applied to the
redemption of Securities of the series in respect of which it was made as
provided for by the terms of such Securities.

SECTION 502.  Satisfaction of Sinking Fund Payments with Securities.

          The Company (a) may deliver to the Trustee Outstanding Securities
(other than any previously called for redemption) of a series in respect of
which a mandatory sinking fund payment is to be made and (b) may apply as a
credit Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities or Outstanding Securities purchased by the Company, in each case
in satisfaction of all or any part of such mandatory sinking fund payment with
respect to the Securities of such series; provided, however, that no Securities
shall be applied in satisfaction of a mandatory sinking fund payment if such
securities shall have been previously so applied.  Securities so applied shall
be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such mandatory sinking fund payment shall be reduced
accordingly.

SECTION 503.  Redemption of Securities for Sinking Fund.

          Not less than 45 days prior to each sinking fund payment date for the
Securities of any series, the Company shall deliver to the Trustee an Officer's
Certificate specifying:

          (a)  the amount of the next succeeding mandatory sinking fund payment
     for such series;

          (b)  the amount, if any, of the optional sinking fund payment to be
     made together with such mandatory sinking fund payment;

          (c)  the aggregate sinking fund payment;

          (d)  the portion, if any, of such aggregate sinking fund payment which
     is to be satisfied by the payment of cash;

          (e)  the portion, if any, of such aggregate sinking fund payment which
     is to be satisfied by delivering and crediting Securities of such series
     pursuant to section 502 and stating the basis for such credit and that such
     Securities have not previously been so credited, and the Company shall also
     deliver to the Trustee any Securities to be so delivered.  If the Company
     shall not deliver such Officer's Certificate, the next succeeding sinking
     fund payment for such series shall be made entirely in cash in the amount
     of the mandatory sinking fund payment.  Not less than 30 days before each
     such sinking fund payment date the Trustee shall select the Securities to
     be redeemed upon such sinking fund payment date in the manner specified in
     Section 403 and cause notice of the redemption thereof to be given in the
     name of and at the expense of the Company in the manner provided in Section
     404.  Such notice having been duly given, the redemption of such Securities
     shall be made upon the terms and in the manner stated in Sections 405 and
     406.

SECTION 601.  Payment of Principal, Premium and Interest.

          The Company shall pay the principal of and premium, if any, and

                                      -31-
<PAGE>

          The Company shall maintain in each Place of Payment for the Securities
of each series an office or agency where payment of such Securities shall be
made, where the registration of  transfer or exchange of such Securities may be
effected and where notices and demands to or upon the Company in respect of such
Securities and this Indenture may be served.  The Company shall give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency and prompt notice to the Holders of any such
change in the manner specified in Section 106.  If at any time the Company shall
fail to maintain any such required office or agency in respect of Securities of
any series, or shall fail to furnish the Trustee with the address thereof,
payment of such Securities shall be made, registration of transfer or exchange
thereof may be effected and notices and demands in respect thereof may be served
at the Corporate Trust Office of the Trustee, and the Company hereby appoints
the Trustee as its agent for all such purposes in any such event.

          The Company may also from time to time designate one or more other
offices or agencies with respect to the Securities of one or more series, for
any or all of the foregoing purposes and may from time to time rescind such
designations; provided, however, that, unless otherwise specified as
contemplated by Section 301 with respect to the Securities of such series, no
such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency for such purposes in each Place of
Payment for such Securities in accordance with the requirements set forth above.
The Company shall give prompt written notice to the Trustee, and prompt notice
to the Holders in the manner specified in Section 106, of any such designation
or rescission and of any change in the location of any such other office or
agency.

          Anything herein to the contrary notwithstanding, any office or agency
required by this Section may be maintained at an office of the Company, in which
event the Company shall perform all functions to be performed at such office or
agency.

SECTION 603.  Money for Securities Payments to Be Held in Trust.

          If the Company shall at any time act as its own Paying Agent with
respect to the Securities of any series, it shall, on or before each due date of
the principal of and premium, if any, and interest, if any, on any of such
Securities,  segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal and premium or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided.  The Company shall promptly notify the Trustee of any
failure by the Company (or any other obligor on such Securities) to make any
payment of principal of or premium, if any, or interest, if any, on such
Securities.

          Whenever the Company shall have one or more Paying Agents for the
Securities of any series, it shall, on or before each due date of the principal
of and premium, if any, and interest, if any, on such Securities, deposit with
such Paying Agents sums sufficient (without


                                      -32-
<PAGE>

duplication) to pay the principal and premium or interest so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such
principal, premium or interest, and (unless such Paying Agent is the Trustee)
the Company shall promptly notify the Trustee of any failure by it so to act.

          The Company shall cause each Paying Agent for the Securities of any
series, other than the company or the Trustee, to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent shall:

          (a)  hold all sums held by it for the payment of the principal of and
     premium, if any, or interest, if any, on such Securities in trust for the
     benefit of the Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

          (b)  give the Trustee notice of any failure by the Company (or any
     other obligor upon such Securities) to make any payment of principal of or
     premium, if any, or interest, if any, on such Securities; and

          (c)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent and furnish to the Trustee such
     information as it possesses regarding the names and addresses of the
     Persons entitled to such sums.

          The Company may at any time pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those
upon which such sums to be held by the Company or such Paying Agent and, if so
stated in a Company order delivered to the Trustee, in accordance with the
provisions of Article Seven; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of and premium, if
any, or interest, if any, on any Security and remaining unclaimed for two years
after such principal and premium, if any, or interest has become due and payable
shall be paid to the Company on Company Request, or, if then held by the
Company, shall be discharged from such trust; and, upon such payment or
discharge, the Holder of such Security shall, as an unsecured general creditor
and not as a Holder of an Outstanding Security, look only to the Company for
payment of the amount so due and payable and remaining unpaid, and all liability
of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any


                                      -33-
<PAGE>

such payment to the Company, may at the expense of the Company cause to be
mailed, on one occasion only, notice to such Holder 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 paid to the Company.

shall do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence.

common with others, make reasonable effort to cause) to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as,
in the judgment of the Company, may be necessary so that the business carried on
in connection therewith may be properly conducted; provided, however, that
nothing in this Section shall prevent the Company from discontinuing, or causing
the discontinuance of, the operation and maintenance of any of its properties if
such discontinuance is, in the judgment of the Company, desirable in the conduct
of its business.

need not comply with Section 102, executed by the principal executive officer,
the principal financial officer or the principal accounting officer of the
Company, as to such officer's knowledge of the Company's compliance with all
conditions and covenants under this Indenture, such compliance to be determined
without regard to any period of grace or requirement of notice under this
Indenture.

SECTION 607.  Waiver of Certain Covenants.

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in (a) Section 602 or any additional
covenant or restriction specified with respect to the Securities of any series,
as contemplated by Section 301, if before the time for such compliance the
Holders of at least a majority in aggregate principal amount of the Outstanding
Securities of all series with respect to which compliance with Section 602 or
such additional covenant or restriction is to be omitted, considered as one
class, shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such


                                      -34-

before the time for such compliance the Holders of at least a majority in
principal amount of Securities Outstanding under this Indenture shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition; but, in the case of (a) or
(b), no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect; provided, however, that so long as a Trust holds Securities of any
series, such Trust may not waive compliance or waive any default in compliance
by the Company with any covenant or other term contained in this Indenture or
the Securities of such series without the approval of the holders of at least a
majority in aggregate liquidation preference of the outstanding Preferred
Securities issued by such Trust affected, obtained as provided in the Trust
Agreement pertaining to such Trust.

SECTION 608.  Restriction on Payment of Dividends.

          So long as any Preferred Securities of any series remain outstanding,
the Company shall not declare or pay any dividend on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the Company's

if at such time (a) the Company shall be in default with respect to its payment
or other obligations under the Guarantee relating to such Preferred Securities,
(b) there shall have occurred and be continuing a payment default (whether
before or after expiration of any period of grace) or an Event of Default
hereunder or (c) the Company shall have elected to extend any interest payment
period as provided in Section 311, and any such period, or any extension
thereof, shall be continuing.

SECTION 609.  Maintenance of Trust Existence.

Company shall (i) maintain direct or indirect ownership of all interests in the
Trust which issued such Preferred Securities, other than such Preferred

thereof, shall be deemed to have been paid for all purposes of this Indenture,
and the entire indebtedness of the Company in respect thereof shall be deemed to
have been satisfied and discharged, if there shall have been irrevocably
deposited with the Trustee or any Paying Agent (other than the Company), in
trust:

          (a)  money in an amount which shall be sufficient, or

          (b)  in the case of a deposit made prior to the Maturity Date of such
     Securities or portions thereof, Government Obligations, which shall not
     contain provisions permitting the redemption or other prepayment thereof at
     the option of the issuer thereof, the principal of and the interest on
     which when due, without any regard to reinvestment thereof, will provide
     moneys which, together with the money, if any, deposited with or held by
     the Trustee or such Paying Agent, shall be sufficient, or

          (c)  a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due
and to become due on such Securities or portions thereof on or prior to the
Maturity Date; provided, however, that in the case of the provision for payment
or redemption of less than all the Securities of any series, such Securities or
portions thereof shall have been selected by the Trustee as provided herein and,
in the case of a redemption, the notice requisite to the validity of such
redemption shall have been given or irrevocable authority shall have been given
by the Company to the Trustee to give such notice, under arrangements
satisfactory to the Trustee; and provided, further, that the Company shall have
delivered to the Trustee and such Paying Agent:

               (x)  if such deposit shall have been made prior to the Maturity
          Date of such Securities, a Company Order stating that the money and
          Government Obligations deposited in accordance with this Section shall
          be held in trust, as provided in Section 703; and

          Opinion of Counsel that the obligations so deposited constitute
          Government Obligations and


                                      -36-
<PAGE>

          do not contain provisions permitting the redemption or other
          prepayment at the option of the issuer thereof, and an opinion of an
          independent public accountant of nationally recognized standing,
          selected by the Company, to the effect that the requirements set forth
          in clause (b) above have been satisfied; and

               (z)  if such deposit shall have been made prior to the Maturity
          Date of such Securities, an Officer's Certificate stating the
          Company's intention that, upon delivery of such Officer's Certificate,
          its indebtedness in respect of such securities or portions thereof
          will have been satisfied and discharged as contemplated in this
          Section.

          Upon the deposit of money or Government Obligations, or both, in
accordance with this Section, together with the documents required by clauses
(x), (y) and (z) above, the Trustee shall, upon receipt of a Company Request,
acknowledge in writing that the Security or securities or portions thereof with
respect to which such deposit was made are deemed to have been paid for all
purposes of this Indenture and that the entire indebtedness of the Company in
respect thereof has been satisfied and discharged as contemplated in this
Section.  In the event that all of the conditions set forth in the preceding
paragraph shall have been satisfied in respect of any Securities or portions
thereof except that, for any reason, the Officer's Certificate specified in
clause (z) shall not have been delivered, such Securities or portions thereof
shall nevertheless be deemed to have been paid for all purposes of this

nevertheless be no longer entitled to the benefits of this Indenture or of any
of the covenants of the Company under Article Six (except the covenants
contained in Sections 602 and 603) or any other covenants made in respect of
such Securities or portions thereof as contemplated by Section 301, but the
indebtedness of the Company in respect of such Securities or portions thereof
shall not be deemed to have been satisfied and discharged prior to the Maturity
Date for any other purpose, and the Holders of such Securities or portions
thereof shall continue to be entitled to look to the Company for payment of the
indebtedness represented thereby; and, upon Company Request, the Trustee shall
acknowledge in writing that such Securities or portions thereof are deemed to
have been paid for all purposes of this Indenture.

          If payment at Stated Maturity of less than all of the Securities of
any series is to be provided for in the manner and with the effect provided in
this Section, the Security Registrar shall select such Securities, or portions
of principal amount thereof, in the manner specified by Section 403 for
selection for redemption of less than all the Securities of a series.

          In the event that Securities which shall be deemed to have been paid
for purposes of this Indenture, and, if such is the case, in respect of which
the Company's indebtedness shall have been satisfied and discharged, all as
provided in this Section do not mature and are not to be redeemed within the 60
day period commencing with the date of the deposit of moneys or Government
obligations, as aforesaid, the Company shall, as promptly as practicable, give a


                                      -37-
<PAGE>

notice, in the same manner as a notice of redemption with respect to such
Securities, to the Holders of such Securities to the effect that such deposit
has been made and the effect thereof.

          Notwithstanding that any Securities shall be deemed to have been paid
for purposes of this Indenture, as aforesaid, the obligations of the Company and
the Trustee in respect of such Securities under Sections 304, 305, 306, 404, 503
(as to notice of redemption), 602, 603, 907 and 915 and this Article Seven shall
survive.

          The Company shall pay, and shall indemnify the Trustee or any Paying
Agent with which Government Obligations shall have been deposited as provided in
this Section against, any tax, fee or other charge imposed on or assessed
against such Government Obligations or the principal or interest received in
respect of such Government Obligations, including, but not limited to, any such
tax payable by any entity deemed, for tax purposes, to have been created as a
result of such deposit.

          Anything herein to the contrary notwithstanding, (a) if, at any time
after a Security would be deemed to have been paid for purposes of this
Indenture, and, if such is the case, the Company's indebtedness in respect
thereof would be deemed to have been satisfied or discharged, pursuant to this
Section (without regard to the provisions of this paragraph), the Trustee or any
Paying Agent, as the case may be, shall be required to return the money or
Government Obligations, or combination thereof, deposited with it as aforesaid
to the Company or its representative under any applicable Federal or State
bankruptcy, insolvency or other similar law, such Security shall thereupon be
deemed retroactively not to have been paid and any satisfaction and discharge of
the Company's indebtedness in respect thereof shall retroactively be deemed not
to have been effected, and such Security shall be deemed to remain Outstanding
and (b) any satisfaction and discharge of the Company's indebtedness in respect
of any Security shall be subject to the provisions of the last paragraph of
Section 603.

SECTION 702.  Satisfaction and Discharge of Indenture.

          This Indenture shall upon Company Request cease to be of further
effect (except as hereinafter expressly provided), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

          (a)  no Securities remain Outstanding hereunder; and

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

provided, however, that if, in accordance with the last paragraph of Section
701, any security, previously deemed to have been paid for purposes of this
Indenture, shall be deemed retroactively not to have been so paid, this
Indenture shall thereupon be deemed retroactively not to have been


                                      -38-
<PAGE>

satisfied and discharged, as aforesaid, and to remain in full force and effect,
and the Company shall execute and deliver such instruments as the Trustee shall
reasonably request to evidence and acknowledge the same.

          Notwithstanding the satisfaction and discharge of this indenture as
aforesaid, the obligations of the Company and the Trustee under Sections 304,
305, 306, 404, 503 (as to notice of redemption), 602, 603, 907 and 915 and this
Article Seven shall survive.

          Upon satisfaction and discharge of this Indenture as provided in this
Section, the Trustee shall assign, transfer and turn over to the Company,
subject to the lien provided by Section 907, any and all money, securities and
other property then held by the Trustee for the benefit of the Holders of the
Securities other than money and Government Obligations held by the Trustee
pursuant to Section 703.

SECTION 703.  Application of Trust Money.

Section 701, nor the principal or interest payments on any such Government
Obligations, shall be withdrawn or used for any purpose other than, and shall be
held in trust for, the payment of the principal of and premium, if any, and
interest, if any, on the Securities or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions
of Section 603; provided, however, that, so long as there shall not have
occurred and be continuing an Event of Default any cash received from such
principal or interest payments on such Government Obligations, if  not then
needed for such purpose, shall, to the extent practicable, be invested in
Government Obligations of the type described in clause (b) in the first
paragraph of Section 701 maturing at such times and in such amounts as shall be
sufficient to pay when due the principal of and premium, if any, and interest,
if any, due and to become due on such Securities or portions thereof on and
prior to the Maturity Date thereof, and interest earned from such reinvestment
shall be paid over to the Company as received, free and clear of any trust, lien
or pledge under this Indenture except the lien provided by Section 907; and
provided, further, that, so long as there shall not have occurred and be
continuing an Event of Default, any moneys held in accordance with this Section
on the Maturity Date of all such Securities in excess of the amount required to
pay the principal of and premium, if any, and interest, if any, then due on such
Securities shall be paid over to the Company free and clear of any trust, lien
or pledge under this Indenture except the lien provided by Section 907; and
provided, further, that if an Event of Default shall have occurred and be
continuing, moneys to be paid over to the Company pursuant to this Section shall
be held until such Event of Default shall have been waived or cured.

     prohibited by the provisions of Article Fifteen hereof); provided, however,
     that a valid extension of the interest payment period by the Company as
     contemplated in Section 311 of this Indenture shall not constitute a
     failure to pay interest for this purpose; or

          (b)  failure to pay the principal of or premium, if any, on any
     Security of such series at its Maturity Date (whether or not payment is

     such default or breach and requiring it to be remedied and stating that
     such notice is a "Notice of Default" hereunder, unless the Trustee, or the
     Trustee and the Holders of a principal amount of securities of such series
     not less than the principal amount of securities the Holders of which gave
     such notice, as the case may be, shall agree in writing to an extension of
     such period prior to its expiration; provided, however, that the Trustee,
     or the Trustee and the Holders of such principal amount of Securities of
     such series, as the case may be, shall be deemed to have agreed to an
     extension of such period if corrective action is initiated by the Company
     within such period and is being diligently pursued; or

          (d)  the entry by a court having jurisdiction in the premises of (1) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or (2) a decree or order adjudging the
     Company a bankrupt or insolvent, or approving as properly filed a petition

     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in a case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or to the commencement of any
     bankruptcy or insolvency case or proceeding against it, or the filing by it
     of a petition or answer or consent seeking reorganization or relief under
     any applicable Federal or State law, or the consent by it to the filing of
     such petition or to the appointment of or taking possession by a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or 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 creditors, or the admission by it in
     writing of its inability to pay its debts generally as they become due, or
     the authorization of such action by the Board of Directors; or

          (f)  any other Event of Default specified with respect to Securities
     of such series.

SECTION 802.  Acceleration of Maturity; Rescission and Annulment.

          (a)  If an Event of Default with respect to Securities of any series
at the time Outstanding shall have occurred and be continuing, either the
Trustee or the Holders of not less than 33% in principal amount of the
Securities of such series may then declare the principal of all Securities of
such series and interest accrued thereon to be due and payable immediately
provided that, in the case of Securities of a series issued to a Trust, if, upon
an Event of Default, the Trustee or the Holders of not less than 33% in
principal amount of the Outstanding Securities of that series fail to declare
the principal of all the Securities of that series to be immediately due and
payable, the holders of at least 33% in aggregate liquidation amount of the
corresponding series of Preferred Securities then outstanding (if any) shall
have such right by a notice in writing to the Company and the Trustee; and upon
any such declaration such principal amount (or specified amount) of and the
accrued interest (including any Additional Interest Attributable to Taxes) on
all the Securities of that series shall become immediately due and payable
(provided that the payment of principal and interest on such Securities shall
remain subordinated to the extent provided in Article Fifteen hereof).


          (b)  At any time after such a declaration of acceleration with respect
to Securities of any series shall have been made pursuant to paragraph (a) above
and before a judgment or decree for payment of the money due shall have been
obtained by the Trustee as hereinafter in this Article provided, the Event or
Events of Default giving rise to such declaration of acceleration


                                      -41-
<PAGE>

shall, without further act, be deemed to have been waived, and such declaration
and its consequences shall, without further act, be deemed to have been
rescinded and annulled, if

          (i)  the Company shall have paid or deposited with the Trustee a sum
     sufficient to pay

               (1)  all overdue interest on all Securities of such series;

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

               (3)  to the extent that payment of such interest is lawful,
          interest upon overdue interest, if any, at the rate or rates
          prescribed therefor in such Securities;

               (4)  all amounts due to the Trustee under Section 907;

          and

          (ii) any other Event or Events of Default with respect to Securities
     of such series, other than the nonpayment of the principal of Securities of
     such series which shall have become due solely by such declaration of
     acceleration, shall have been cured or waived as provided in Section 813.

No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereon.

SECTION 803.  Collection of Indebtedness and Suits for Enforcement by Trustee.


          If an Event of Default described in clause (a) or (b) of Section 801
shall have occurred and be continuing, the Company shall, upon demand of the
Trustee, pay to it, for the benefit of the Holders of the Securities of the
series with respect to which such Event of Default shall have occurred, the
whole amount then due and payable on such Securities for principal and premium,
if any, and interest, if any, and, to the extent permitted by law, interest on
premium, if any, and on any overdue principal and interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under
Section 907.

          If the Company shall fail to pay such amounts 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, may prosecute such proceeding to Judgment or final decree and may
enforce the same against the Company or any other obligor upon such Securities


                                      -42-
<PAGE>

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
Securities, wherever situated.

          If an Event of Default with respect to Securities of any series shall
have occurred and be continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series 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 804.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

          (a)  to file and prove a claim for the whole amount of principal,
     premium, if any, and interest, if any, owing and unpaid in respect of the
     Securities 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 amounts due to the Trustee under Section 907) and of the Holders
     allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each 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 the Holders, to
pay to the Trustee any amounts due it under Section 907.

          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 Securities
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 805.  Trustee May Enforce Claims Without Possession of Securities.


                                      -43-
<PAGE>

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the securities 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 in respect of which such judgment has been
recovered.

SECTION 806.  Application Of Money Collected.

          Subject to the provisions of Article Fifteen, any money collected by
the Trustee pursuant to this Article shall be applied in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal or premium, if any, or interest, if any, upon
presentation of the Securities in respect of which or for the benefit of which
such money shall have been collected and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

          First:  To the payment of all amounts due the Trustee under Section
     907;

          Second:  To the payment of the amounts then due and unpaid upon the
     Securities for principal of and premium, if any, and interest, if any, in
     respect of which or for the benefit of which such money has been collected,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on such Securities for principal, premium, if any,
     and interest, if any, respectively; and

          Third:  To the payment of the remainder, if any, to the Company or to
     whomsoever may be lawfully entitled to receive the same or as a court of
     competent jurisdiction way direct.

SECTION 807.  Limitation on Suits.

          No Holder shall have any right to institute any proceedings, judicial
or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

          (a)  such Holder shall have previously given written notice to the
     Trustee of a continuing Event of Default with respect to the Securities of
     such series;

          (b)  the Holders of not less then a majority in aggregate principal
     amount of the Outstanding Securities of all series in respect of which an
     Event of Default shall have occurred and be continuing, considered as one
     class, shall have made written request to the


                                      -44-
<PAGE>

     Trustee to institute proceedings in respect of such Event of Default in its
     own name as Trustee hereunder;

          (c)  such Holder or Holders shall have offered to the Trustee
     reasonable indemnity against the costs, expenses and liabilities to be
     incurred in compliance with such request;

          (d)  the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity shall have failed to institute any such proceeding;
     and

          (e)  no direction inconsistent with such written request shall have
     been given to the Trustee during such 60-day period by the Holders of a
     majority in aggregate principal amount of the Outstanding Securities of all
     series in respect of which an Event of Default shall have occurred and be
     continuing, considered as one class;

it being understood and intended that no one or more of such Holders 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 of
such Holders or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 808.  Unconditional Right of Holders to Receive Principal, Premium and
Interest.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Sections 307 and 311) interest (including any Additional Interest Attributable
to Taxes) on such Security on the Stated Maturity or Maturities expressed in
such Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.  In the case of Securities
of a series issued to a Trust, any holder of the corresponding series of
Preferred Securities shall have the right, upon the occurrence of an Event of
Default described in Section 801(a) or 801(b) hereof, to institute a suit
directly against the Company for enforcement of payment to such holder of
principal of (and premium, if any) and (subject to Sections 307 and 311)
interest (including any Additional Interest Attributable to Taxes) on the
Securities of such series having a principal amount equal to the aggregate
liquidation preference of the Preferred Securities of the corresponding series
held by such holder.

SECTION 809.  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding shall have been
discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee or to such Holder, then and


                                      -45-
<PAGE>

in every such case, subject to any determination in such proceeding, the
Company, and Trustee and such Holder shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and such Holder shall continue as though no such
proceeding had been instituted.

SECTION 810.  Rights and Remedies Cumulative.

          Except as otherwise provided in the last paragraph of Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 811.  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein.  Every right and remedy given by this Article or by law to the Trustee
or to the Holders say be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 812.  Control by Holders of Securities.

          If an Event of Default shall have occurred and be continuing in
respect of a series of Securities, the Holders of a majority in principal amount
of the Outstanding Securities of such series 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, with
respect to the Securities of such series; provided, however, that if an Event of
Default shall have occurred and be continuing with respect to more than one
series of Securities, the Holders of a majority in aggregate principal amount of
the Outstanding Securities of all such series, considered as one class, shall
have the right to make such direction, and not the Holders of the Securities of
any one of such series; and provided, further, that such direction shall not be
in conflict with any rule of law or with this Indenture.  Before proceeding to
exercise any right or power hereunder at the direction of such Holders, the
Trustee shall be entitled to receive from such Holders reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by
it in compliance with any such direction.

SECTION 813.  Waiver of Past Defaults.


                                      -46-
<PAGE>

          The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder and its consequences
with respect to such series, and, in the case of Securities of a series issued
to a Trust, should the holders of such Securities fail to waive such default,
the holders of a majority in aggregate liquidation preference of the related
series of Preferred Securities shall have such right, in each case except for a
default

          (a)  in the payment of the principal of or premium, if any, or
     interest (including any Additional Interest Attributable to Taxes) on any
     Security of such series, or

          (b)  in respect of a covenant or provision hereof which under Section
     1202 cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected;

provided, however, that so long as a Trust holds the Securities of any series,
such Trust may not waive any past default without the consent of at least a
majority in aggregate liquidation preference of the outstanding Preferred
Securities issued by such Trust affected, obtained as provided in the Trust
Agreement pertaining to such Trust.

          Upon any such waiver, such default shall cease to exist, and any and
all Events of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

SECTION 814.  Undertaking for Costs.

          The Company and the Trustee agree, and each Holder by his 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, suffered 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 the provisions of
this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in aggregate principal amount of
the Outstanding Securities of all series in respect of which such suit may be
brought, considered as one class, or to any suit instituted by any Holder for
the enforcement of the payment of the principal of or premium, if any, or
interest, if any, on any Security on or after the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on or after the
Redemption Date).

SECTION 815.  Waiver of Stay or Extension Laws.


                                      -47-
<PAGE>

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  ARTICLE NINE

                                   The Trustee

SECTION 901.  Certain Duties and Responsibilities.

          (a)  The Trustee shall have and be subject to all the duties and
     responsibilities specified with respect to an indenture trustee in the
     Trust Indenture Act and no implied covenants or obligations shall be read
     into this Indenture against the Trustee.

          (b)  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.

          (c)  Notwithstanding anything contained in this indenture to the
     contrary, the duties and responsibilities of the Trustee under this
     Indenture shall be subject to the protections, exculpations and limitations
     on liability afforded to the Trustee under the provisions of the Trust
     Indenture Act.

          (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.

SECTION 902.  Notice of Defaults.

          The Trustee shall give notice of any default hereunder with respect to
the Securities of any series to the Holders of Securities of such series in the
manner and to the extent required to do so by the Trust Indenture Act, unless
such default shall have been cured or waived; provided, however, that in the
case of any default of the character specified in Section 801(c), no such notice
to Holders shall be given until at least 45 days after the occurrence thereof.
For the

<PAGE>

          (a)  pay to the Trustee from time to time reasonable compensation for

     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (b)  except as otherwise expressly provided herein, reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and

Trustee hereunder.

          In addition to the rights provided to the Trustee pursuant to the
provisions of the immediately preceding paragraph of this Section 907, when the
Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 801(d) or Section 801(e), the expenses (including
the reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable Federal or State bankruptcy, insolvency or other similar law.

SECTION 908.  Disqualification; Conflicting Interests.

          If the Trustee shall have or acquire any conflicting interest within
the meaning of the Trust Indenture Act, it shall either eliminate such
conflicting interest or resign to the extent, in the manner and with the effect,
and subject to the conditions, provided in the Trust Indenture Act and this
Indenture.  For purposes of Section 310(b)(l) of the Trust Indenture Act and to
the extent permitted thereby, the Trustee, in its capacity as trustee in respect
of the Securities of any series, shall not be deemed to have a conflicting
interest arising from its capacity as trustee in respect of the Securities of
any other series.  The Trust Agreement and the Guarantee Agreement


                                      -51-

pertaining to each Trust shall be deemed to be specifically described in this
Indenture for the purposes of clause (i) of the first proviso contained in
Section 310(b) of the Trust Indenture Act.

SECTION 909.  Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder which shall be

          (a)  a corporation organized and doing business under the laws of the
     United States, any State or Territory 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 and subject to
     supervision or examination by Federal or State authority, or

          (b)  if and to the extent permitted by the Commission by rule,
     regulation or order upon application, a corporation or other Person
     organized and doing business under the laws of a foreign government,
     authorized under such laws to exercise corporate trust powers, having a
     combined capital and surplus of at least $50,000,000 or the Dollar
     equivalent of the applicable foreign currency and subject to supervision or
     examination by authority of such foreign government or a political
     subdivision thereof substantially equivalent to supervision or examination
     applicable to United States institutional trustees,

and, in either ease, qualified and eligible under this Article and the Trust
Indenture Act.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of such supervising or
examining authority, then for the purposes of this Section, 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, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

SECTION 910.  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 shall become effective until the

     applicable requirements of Section 911.

          (b)  The Trustee may resign at any time with respect to the Securities
     of one or more series by giving written notice thereof to the Company. If
     the instrument of acceptance by a successor Trustee required by Section 911
     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 with respect to the Securities of such series.


                                      -52-
<PAGE>

          (c)  The Trustee may be removed at any time with respect to the
     Securities of any series by Act of the Holders of a majority in principal
     amount of the Outstanding Securities of such series delivered to the
     Trustee and to the Company; provided that so long as any Preferred
     Securities remain outstanding, the Trust which issued such Preferred
     Securities shall not execute any Act to remove the Trustee without the
     consent of the holders of a majority in aggregate liquidation preference of
     Preferred Securities issued by such Trust outstanding, obtained as provided
     in the Trust Agreement pertaining to such Trust.

          (d)  If at any time:

               (1)  the Trustee shall fail to comply with Section 908 after
          written request therefor by the Company or by any Holder who has been
          a bona fide Holder for at least six months, or

               (2)  the Trustee shall cease to be eligible under Section 909 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, (x) the Company by a Board Resolution may remove the
Trustee with respect to all Securities or (y) subject to Section 814, any Holder
who has been a bona fide Holder for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities 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
     (other than as contemplated in clause (y) in subsection (d) of this
     Section), with respect to the Securities of one or more series, the
     Company, by a Board Resolution, shall promptly appoint a successor Trustee
     or Trustees with respect to the Securities of that or those series (it
     being understood that any such successor Trustee may be appointed with
     respect to the Securities of one or more or all of such series and that at
     any time there shall be only one Trustee with respect to the Securities of
     any particular series) and shall comply with the applicable requirements of
     Section 911.  If, within one year after such resignation, removal or
     incapability, or the occurrence of such vacancy, a successor Trustee with
     respect to the Securities of any series shall be appointed by Act of the
     Holders of a majority in principal amount of the Outstanding Securities of
     such series delivered to the Company and the retiring Trustee, the
     successor Trustee so appointed shall, forthwith upon its acceptance of such
     appointment in


                                      -53-
<PAGE>

     accordance with the applicable requirements of Section 911, become the
     successor Trustee with respect to the Securities of such series and to that
     extent supersede the successor Trustee appointed by the Company.  If no
     successor Trustee with respect to the Securities of any series shall have
     been so appointed by the Company or the Holders and accepted appointment in
     the manner required by Section 911, any Holder who has been a bona fide
     Holder of a Security of such series for at least six months may, on behalf
     of itself and all others similarly situated, petition any court of
     competent jurisdiction for the appointment of a successor Trustee with
     respect to the Securities of such series.

          (f)  So long as no event which is, or after notice or lapse of time,
     or both, would become, an Event of Default shall have occurred and be
     continuing, and except with respect to a Trustee appointed by Act of the
     Holders of a majority in principal amount of the Outstanding Securities
     pursuant to subsection (e) of this Section, if the Company shall have
     delivered to the Trustee (i) a Board Resolution appointing a successor
     Trustee, effective as of a date specified therein, end (ii) an instrument
     of acceptance of such appointment, effective as of such date, by such
     successor Trustee in accordance with Section 911, the Trustee shall be
     deemed to have resigned as contemplated in subsection (b) of this Section,
     the successor Trustee shall be deemed to have been appointed by the Company
     pursuant to subsection (e) of this Section and such appointment shall be
     deemed to have been accepted as contemplated in Section 911, all as of such
     date, and all other provisions of this Section and Section 911 shall be
     applicable to such resignation, appointment and acceptance except to the
     extent inconsistent with this subsection (f).

          (g)  The Company shall give notice of each resignation and each
     removal of the Trustee with respect to the Securities of any series and
     each appointment of a successor Trustee with respect to the Securities of
     any series by mailing written notice of such event by first-class mail,
     postage prepaid, to all Holders of Securities of such series as their names
     and addresses appear in the Security Register.  Each notice shall include
     the name of the successor trustee with respect to the Securities of such
     series and the address of its corporate trust office.

SECTION 911.  Acceptance of Appointment by Successor.

          (a)  In case of the appointment hereunder of a successor Trustee with
     respect to the Securities of all series, every such successor Trustee so
     appointed 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 all sums owed to it,
     execute and deliver an instrument transferring to such successor Trustee
     all the rights, powers and trusts of the retiring


                                      -54-
<PAGE>

     Trustee and shall duly assign, transfer and deliver to such successor
     Trustee all property and money held by such retiring Trustee hereunder.

          (b)  In case of the appointment hereunder of a successor Trustee with
     respect to the Securities of one or more (but not all) series, the Company,
     the retiring Trustee and each successor Trustee with respect to the
     Securities of one or more series shall execute and deliver an indenture
     supplemental hereto wherein each successor Trustee shall accept such
     appointment and which (1) shall contain such provisions as shall be
     necessary or desirable to transfer and confirm to, and to vest in, each
     successor Trustee all the rights, powers, trusts and duties of the retiring
     Trustee with respect to the Securities of that or those series to which the
     appointment of such successor Trustee relates, (2) if the retiring Trustee
     is not retiring with respect to all Securities, shall contain such
     provisions as shall be deemed necessary or desirable to confirm that all
     the rights, powers, trusts and duties of the retiring Trustee with respect
     to the Securities of that or those series as to which the retiring Trustee
     is not retiring shall continue to be vested in the retiring Trustee and (3)
     shall add to or change any of the provisions of this Indenture as shall be
     necessary to provide for or facilitate the administration of the trusts
     hereunder by more than one Trustee, it being understood that nothing herein
     or in such supplemental indenture shall constitute such Trustees
     co-trustees of the same trust and that each such Trustee shall be trustee
     of a trust or trusts hereunder separate and apart from any trust or trusts
     hereunder administered by any other such Trustee; and upon the execution
     and delivery of such supplemental indenture the resignation or removal of
     the retiring Trustee shall become effective to the extent provided therein
     and each 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 with respect to the Securities of that or
     those series to which the appointment of such successor Trustee relates;
     but, on request of the Company or any successor Trustee, such retiring
     Trustee, upon payment of all sums owed to it, shall duly assign, transfer
     and deliver to such successor Trustee all property and money held by such
     retiring Trustee hereunder with respect to the Securities of that or those
     series to which the appointment of such successor Trustee relates.

          (c)  Upon request of any such successor Trustee, the Company shall
     execute any instruments which fully vest in and confirm to such successor
     Trustee all such rights, powers and trusts referred to in subsection (a) or
     (b) of this Section, as the case may be.

          (d)  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.

SECTION 912.  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


                                      -55-
<PAGE>

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 Securities 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 Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 913.  Preferential Collection of Claims Against Company.

          If the Trustee shall be or become a creditor of the Company or any
other obligor upon the Securities (other than by reason of a relationship
described in Section 311(b) of the Trust Indenture Act), the Trustee shall be
subject to any and all applicable provisions of the Trust Indenture Act
regarding the collection of claims against the Company or such other obligor.
For purposes of Section 311(b) of the Trust Indenture Act:

          (a)  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;

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

SECTION 914.  Co-trustees and Separate Trustees.

          At any time or times, for the purpose of meeting the legal
requirements of any applicable jurisdiction, the Company and the Trustee shall
have power to appoint, and, upon the written request of the Trustee or of the
Holders of at least 33% in principal amount of the Securities then Outstanding,
the Company shall for such purpose join with the Trustee in the execution and
delivery  of all instruments and  agreements necessary or proper to appoint, one
or more Persons approved by the Trustee either to act as co-trustee, jointly

as may be provided in the instrument of appointment, and to vest in such Person
or Persons, in the capacity aforesaid, any property, title,


                                      -56-
<PAGE>

right or power deemed necessary or desirable, subject to the other provisions of
this Section. If the Company does not join in such appointment within 15 days
after the receipt by it of a request so to do, or if an Event of Default shall
have occurred and be continuing, the Trustee alone shall have power to make such
appointment.

          Should any written instrument or instruments from the Company be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed, acknowledged
and delivered by the Company.

          Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following conditions:

          (a)  the Securities shall be authenticated and delivered, and all
     rights, powers, duties and obligations hereunder in respect of the custody
     of securities, cash and other personal property held by, or required to be
     deposited or pledged with, the Trustee hereunder, shall be exercised
     solely, by the Trustee;

          (b)  the rights, powers, duties and obligations hereby conferred or
     imposed upon the Trustee in respect of any property covered by such
     appointment shall be conferred or imposed upon and exercised or performed
     either by the Trustee or by the Trustee and such co-trustee or separate
     trustee jointly, as shall be provided in the instrument appointing such
     co-trustee or separate trustee, except to the extent that under any law of
     any jurisdiction in which any particular act is to be performed, the
     Trustee shall be incompetent or unqualified to perform such act, in which
     event such rights, powers, duties and obligations shall be exercised and
     performed by such co-trustee or separate trustee;

          (c)  the Trustee at any time, by an instrument in writing executed by
     it, with the concurrence of the Company, may accept the resignation of or
     remove any co-trustee or separate trustee appointed under this Section,
     and, if an Event of Default shall have occurred and be continuing, the
     Trustee shall have power to accept the resignation of, or remove, any such
     co-trustee or separate trustee without the concurrence of the Company.
     Upon the written request of the Trustee, the Company shall join with the
     Trustee in the execution and delivery of all instruments and agreements
     necessary or proper to effectuate such resignation or removal. A successor
     to any co-trustee or separate trustee so resigned or removed may be
     appointed in the manner provided in this Section;

          (d)  no co-trustee or separate trustee hereunder shall be personally
     liable by reason of any act or omission of the Trustee, or any other such
     trustee hereunder; and

          (e)  any Act of Holders delivered to the Trustee shall be deemed to
     have been delivered to each such co-trustee and separate trustee.

SECTION 915.  Appointment of Authenticating Agent.


          The Trustee may appoint an Authenticating Agent or Agents with respect
to the Securities of one or more series, which shall be authorized to act on
behalf of the Trustee to authenticate Securities of such series issued upon
original issuance and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities 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 Securities 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, any State or territory 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, 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, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

          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, 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, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company.  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


                                      -58-
<PAGE>

successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

          The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, in accordance
with, and subject to the provisions of Section 907.

          The provisions of Sections 308, 904 and 905 shall be applicable to
each Authenticating Agent.

          If an appointment with respect to the Securities of one or more series
shall be made pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

          This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                                        ________________________
                                        As Trustee

                                           As Authenticating
                                              Agent

                                        By______________________
                                           Authorized Signatory

          If all of the Securities of a series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested by the Company in writing (which writing
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel), shall appoint, in accordance with this Section and in accordance with
such procedures as shall be acceptable to the Trustee, an Authenticating Agent
having an office in a Place of Payment designated by the Company with respect to
such series of Securities.

     become an Event of Default, shall have occurred and be continuing; and

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

SECTION 1102.  Successor Corporation Substituted.

          Upon any consolidation by the Company with or merger by the Company
into any other corporation or any conveyance, or other transfer or lease of the
properties and assets of the Company substantially as an entirety in accordance
with Section 1101, the successor corporation formed by such consolidation or
into which the Company is merged or the Person 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 Person had been named as the Company herein,
and thereafter, except in the case of a lease, the predecessor Person shall be
relieved of all obligations and covenants under this Indenture and the
Securities Outstanding hereunder.

                                 ARTICLE TWELVE

                             Supplemental Indentures

SECTION 1201.  Supplemental Indentures Without Consent of Holders.

          Without the consent of any Holders, the Company and the Trustee, at

          (a)  to evidence the succession of another Person to the Company and
     the assumption by any such successor of the covenants of the Company herein
     and in the Securities, all as provided in Article Eleven; or

          (b)  to add one or more covenants of the Company or other provisions
     for the benefit of all Holders or for the benefit of the Holders of, or to

     long as there shall be Outstanding, Securities of one or more specified

     any series of Securities Outstanding hereunder; or

          (d)  to change or eliminate any provision of this Indenture or to add
     any new provision to this Indenture; provided, however, that if such
     change, elimination or addition shall adversely affect the interests of the
     Holders of Securities of any series Outstanding on the date of such
     indenture supplemental hereto in any material respect, such change,
     elimination or addition shall become effective with respect to such series
     only pursuant to the provisions of Section 1202 hereof or when no Security
     of such series remains Outstanding; or

          (e)  to provide collateral security for all but not part of the

     thereon and for the procedures for the registration, exchange and
     replacement thereof and for the giving of notice to, and the solicitation
     of the vote or consent of, the holders thereof, and for any and all other
     matters incidental thereto; or

          (h)  to evidence and provide for the acceptance of appointment
     hereunder by a separate or successor Trustee with respect to the Securities
     of one or more series and to add to or change any of the provisions of this
     Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee, pursuant
     to the requirements of Section 911(b); or

          (i)  to provide for the procedures required to permit the Company to
     utilize, at its option, a noncertificated system of registration for all,
     or any series of, the Securities; or

          (j)  to change any place or places where (1) the principal of and
     premium, if any, and interest, if any, on all or any series of Securities
     shall be payable, (2) all or any series of Securities may be surrendered
     for registration of transfer, (3) all or any series of Securities may be
     surrendered for exchange and (4) notices and demands to or upon the Company
     in respect of all or any series of Securities and this Indenture may be

                                      -62-
<PAGE>

          (k)  to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other changes to the provisions hereof or to add
     other provisions with respect to matters or questions arising under this
     Indenture, provided that such other changes or additions shall not
     adversely affect the interests of the Holders of Securities of any series
     in any material respect.

          Without limiting the generality  of the foregoing, if the  Trust
Indenture Act as in effect at the date of the execution and  delivery of this
Indenture or  at any time  thereafter shall  be  amended and

               (x)  if any such amendment shall require one or more changes to
          any provisions hereof or the inclusion herein of any additional
          provisions, or shall by operation of law be deemed to effect such
          changes or incorporate such provisions by reference or otherwise, this
          Indenture shall be deemed to have been amended so as to conform to
          such amendment to the Trust Indenture Act, and the Company and the
          Trustee may, without the consent of any Holders, enter into an
          indenture supplemental hereto to effect or evidence such changes or
          additional provisions; or

               (y)  if any such amendment shall permit one or more changes to,
          or the elimination of, any provisions hereof which, at the date of the
          execution and delivery hereof or at any time thereafter, are required
          by the Trust Indenture Act to be contained herein, this Indenture
          shall be deemed to have been amended to effect such changes or
          elimination, and the Company and the Trustee may, without the consent
          of any Holders, enter into an indenture supplemental hereto to
          evidence such amendment hereof.

SECTION 1202.  Supplemental Indentures With Consent of Holders.

          With the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of all series then Outstanding
under this Indenture, considered as one class, by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or modifying
in any manner the rights of the Holders of Securities of such series under the
Indenture; provided, however, that if there shall be Securities of more than one
series Outstanding hereunder and if a proposed supplemental indenture shall
directly affect the rights of the Holders of Securities of one or more, but less
than all, of such series, then the consent only of the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all series so
directly affected, considered as one class, shall be required; and provided,
further, that no such supplemental indenture shall:


                                      -63-
<PAGE>

          (a)  except to the extent permitted by Section 311 or as otherwise
     specified as contemplated by Section 301 with respect to the extension of
     the interest payment period of the Securities of any series, change the
     Stated Maturity of the principal of, or any installment of principal of or
     interest on, any Security, or reduce the principal amount thereof or the
     rate of interest thereon (or the amount of any installment of interest
     thereon) or change the method of calculating such rate or reduce any
     premium payable upon the redemption thereof, or change the coin or currency
     (or other property), in which any Security or any premium or the interest
     thereon is payable, or impair the right to institute suit for the
     enforcement of any such payment on or after the Stated Maturity thereof
     (or, in the case of redemption, on or after the Redemption Date), without,
     in any such case, the consent of the Holder of such Security, or


          (b)  reduce the percentage in principal amount of the Outstanding
     Securities of any series (or, if applicable, in liquidation preference of
     any series of Preferred Securities), the consent of the Holders of which is
     required for any such supplemental indenture, or the consent of the Holders
     of which is required for any waiver of compliance with any provision of
     this Indenture or of any default hereunder and its consequences, or reduce
     the requirements of Section 1304 for quorum or voting, without, in any such
     case, the consent of the Holders of each Outstanding Security of such
     series, or

          (c)  modify any of the provisions of this Section, Section 607 or
     Section 813 with respect to the Securities of any series, except to
     increase the percentages in principal amount referred to in this Section or
     such other Sections or to provide that other provisions of this Indenture
     cannot be modified or waived without the consent of the Holder of each
     Outstanding Security affected thereby; provided, however, that this clause
     shall not be deemed to require the consent of any Holder with respect to
     changes in the references to "the Trustee" and concomitant changes in this
     Section, or the deletion of this proviso, in accordance with the
     requirements of Sections 911(b) and 1201(h).

          Notwithstanding the foregoing, so long as any of the Preferred
Securities remain outstanding, the Trustee may not consent to a supplemental
indenture under this Section 1202 without the prior consent, obtained as
provided in the Trust Agreement pertaining to each Trust which issued such
Preferred Securities, of the holders of not less than a majority in aggregate
liquidation preference of all Preferred  Securities issued by  each such Trust
affected thereby, considered as one class, or, in the case of changes described
in clauses (a), (b) and (c) above, 100% in aggregate liquidation preference of
all such Preferred Securities then outstanding which would be affected thereby,
considered as one class.  A supplemental indenture which changes or eliminates
any covenant or other provision of this Indenture which has expressly been
included solely for the benefit of one or more particular series of Securities,
or which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the
rights under this Indenture of the Holders of Securities of any other series.


                                      -64-
<PAGE>

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.  A waiver by a
Holder of such Holder's right to consent under this Section shall be deemed to
be a consent of such Holder.

SECTION 1203.  Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 901) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties, immunities or liabilities under this Indenture or
otherwise.

SECTION 1204.  Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby. Any supplemental indenture permitted by this Article may
restate this Indenture in its entirety, and, upon the execution and delivery
thereof, any such restatement shall supersede this Indenture as theretofore in
effect for all purposes.

SECTION 1205.  Conformity With Trust Indenture Act.

          Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 1206.  Reference in Securities to Supplemental Indentures.

          Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

SECTION 1207.  Modification Without Supplemental Indenture.


                                      -65-
<PAGE>

          If the terms of any particular series of Securities shall have been
established in a Board Resolution or an Officer's Certificate as contemplated by
Section 301, and not in an indenture supplemental hereto, additions to, changes
in or the elimination of any of such terms may be effected by means of a
supplemental Board Resolution or Officer's Certificate, as the case may be,
delivered to, and accepted by, the Trustee; provided, however, that such
supplemental Board Resolution or Officer's Certificate shall not be accepted by
the Trustee or otherwise be effective unless all conditions set forth in this
Indenture which would be required to be satisfied if such additions,  changes
or elimination  were  contained  in a supplemental indenture shall have been
appropriately satisfied. Upon the acceptance thereof by the Trustee, any such
supplemental Board Resolution or Officer's Certificate shall be deemed to be a
"supplemental indenture" for purposes of Section 1204 and 1206.

                                ARTICLE THIRTEEN

                   Meetings of Holders; Action Without Meeting

     Illinois, as the Trustee shall determine, or, with the approval of the
     Company, at any other place. Notice of every such meeting, setting forth
     the time and the place of such meeting and in general terms the action
     proposed to be taken at such meeting, shall be given, in the manner
     provided in Section 106, not less than 21 nor more than 180 days prior to
     the date fixed for the meeting.

          (b)  If the Trustee shall have been requested to call a meeting of the
     Holders of Securities of one or more, or all, series by the Company or by
     the Holders of 33% in aggregate principal amount of all of such series,
     considered as one class, for any purpose specified in Section 1301, by
     written request setting forth in reasonable detail the action proposed to
     be taken at the meeting, and the Trustee shall not have given the notice of
     such meeting within 21 days after receipt of such request or shall not
     thereafter proceed to cause the meeting to be held as provided herein, then
     the Company or the Holders of Securities of such series in the amount above
     specified, as the case may be, may determine the time and the place in the
     State of Illinois, or in such other place as shall be determined or


                                      -66-
<PAGE>

     approved by the Company, for such meeting and may call such meeting for
     such purposes by giving notice thereof as provided in subsection (a) of
     this Section.

          (c)  Any meeting of Holders of Securities of one or more, or all,
     series shall be valid without notice if the Holders of all Outstanding
     Securities of such series are present in person or by proxy and if
     representatives of the Company and the Trustee are present, or if notice is
     waived in writing before or after the meeting by the Holders of all
     Outstanding Securities of such series, or by such of them as are not
     present at the meeting in person or by proxy, and by the Company and the
     Trustee.

SECTION 1303.  Persons Entitled to Vote at Meetings.

          To be entitled to vote at any meeting of Holders of Securities of one
or more, or all, series a Person shall be (a) a Holder of one or more
Outstanding Securities of such series, or (b) a Person appointed by an

Outstanding Securities of such series by such Holder or Holders.  The only
Persons who shall be entitled to attend any meeting of Holders of Securities of
any series shall be the Persons entitled to vote at such meeting and their
counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

SECTION 1304.  Quorum; Action.

          The Persons entitled to vote a majority in aggregate principal amount
of the Outstanding Securities of the series with respect to which a meeting
shall have been called as herein before provided, considered as one class, shall
constitute a quorum for a meeting of Holders of Securities of such series;
provided, however, that if any action is to be taken at such meeting which this
Indenture expressly provides may be taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of such series, considered as one class, the Persons
entitled to vote such specified percentage in principal amount of the
Outstanding Securities of such series, considered as one class, shall constitute
a quorum. In the absence of a quorum within one hour of the time appointed for
any such meeting, the meeting shall, if convened at the request of Holders of
Securities of such series, be dissolved. In any other case the meeting may be
adjourned for such period as may be determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for such
period as may be determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting. Except as provided by Section 1305(e),
notice of the reconvening of any meeting adjourned for more than 30 days shall
be given as provided in Section 1302(a) not less than 10 days prior to the date
on which the meeting is scheduled to be reconvened. Notice of the reconvening of
an adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

<PAGE>

          Except as limited by Section 1202, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of the
series with respect to which such meeting shall have been called, considered as
one class; provided, however, that, except as so limited, any resolution with
respect to any action which this Indenture expressly provides may be taken by
the Holders of a specified percentage, which is less than a majority, in
principal amount of the Outstanding Securities of such series, considered as one
class, may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in principal amount of the Outstanding Securities
of such series, considered as one class.

          Any resolution passed or decision taken at any meeting of Holders of
Securities duly held in accordance with this Section shall be binding on all the
Holders of Securities of the series with respect to which such meeting shall
have been held, whether or not present or represented at the meeting.

SECTION 1305.  Attendance at Meetings; Determination of Voting Rights; Conduct
and Adjournment of Meetings.

          (a)  Attendance at meetings of Holders of Securities may be in person
     or by proxy; and, to the extent permitted by law, any such proxy shall
     remain in effect and be binding upon any future Holder of the Securities
     with respect to which it was given unless and until specifically revoked by
     the Holder or future Holder of such Securities before being voted.

          (b)  Notwithstanding any other provisions of this Indenture, the
     Trustee may make such reasonable regulations as it may deem advisable for
     any meeting of Holders of Securities in regard to proof of the holding of
     such Securities and of the appointment of proxies and in regard to the
     appointment and duties of inspectors of votes, the submission and
     examination of proxies, certificates and other evidence of the right to
     vote, and such other matters concerning the conduct of the meeting as it
     shall deem appropriate. Except as otherwise permitted or required by any
     such regulations, the holding of Securities shall be proved in the manner
     specified in Section 104 and the appointment of any proxy shall be proved
     in the manner specified in Section 104. Such regulations may provide that
     written instruments appointing proxies, regular on their face, may be
     presumed valid and genuine without the proof specified in Section 104 or
     other proof.

          (c)  The Trustee shall, by an instrument in writing, appoint a
     temporary chairman of the meeting, unless the meeting shall have been
     called by the Company or by Holders as provided in Section 1302(b), in
     which case the Company or the Holders of Securities of the series calling
     the meeting, as the case may be, shall in like manner appoint


                                      -68-
<PAGE>

     a temporary chairman. A permanent chairman and a permanent secretary of the
     meeting shall be elected by vote of the Persons entitled to vote a majority
     in aggregate principal amount of the Outstanding Securities of all series
     represented at the meeting, considered as one class.

          (d)  At any meeting each Holder or proxy shall be entitled to one vote
     for each $1 principal amount of Securities held or represented by him;
     provided, however, that no vote shall be cast or counted at any meeting in
     respect of any Security challenged as not Outstanding and ruled by the
     chairman of the meeting to be not Outstanding. The chairman of the meeting
     shall have no right to vote, except as a Holder of a Security or proxy.

          (e)  Any meeting duly called pursuant to Section 1302 at which a
     quorum is present may be adjourned from time to time by Persons entitled to
     vote a majority in aggregate principal amount of the Outstanding Securities
     of all series represented at the meeting, considered as one class; and the
     meeting may be held as so adjourned without further notice.

SECTION 1306.  Counting Votes and Recording Action of Meetings.

          The vote upon any resolution submitted to any meeting of Holders shall
be by written ballots on which shall be subscribed the signatures of the Holders
or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities, of the series with respect to which the
meeting shall have been called, held or represented by them.  The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports of all
votes cast at the meeting. A record of the proceedings of each meeting of
Holders shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1302 and, if
applicable, Section 1304.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

SECTION 1307.  Action Without Meeting.

          In lieu of a vote of Holders at a meeting as herein before
contemplated in this Article, any request, demand, authorization, direction,
notice, consent, waiver or other action may be made, given or taken by Holders
by written instruments as provided in Section 104.

         Immunity of Incorporators, Stockholders, Officers and Directors

SECTION 1401.  Liability Solely Corporate.

          No recourse shall be had for the payment of the principal of or
premium, if any, or interest, if any, on any Securities, or any part thereof, or
for any claim based thereon or otherwise in respect thereof, or of the
indebtedness represented thereby, or upon any obligation, covenant or agreement
under this Indenture, against any incorporator, stockholder, officer or
director, as such, past, present or future of the Company or of any predecessor
or successor corporation (either directly or through the Company or a
predecessor or successor corporation), whether by virtue of any constitutional
provision, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly agreed and understood that this
Indenture and all the Securities are solely corporate obligations, and that no
personal liability whatsoever shall attach to, or be incurred by, any
incorporator, stockholder, officer or director, past, present or future, of the
Company or of any predecessor or successor corporation, either directly or
indirectly through the Company or any predecessor or successor corporation,
because of the indebtedness hereby authorized or under or by reason of any of
the obligations, covenants or agreements contained in this Indenture or in any
of the Securities or to be implied herefrom or therefrom, and that any such
personal liability is hereby expressly waived and released as a condition of,
and as part of the consideration for, the execution of this Indenture and the
issuance of the Securities.

SECTION 1501.  Securities Subordinate to Senior Indebtedness.

          The Company, for itself, its successors and assigns, covenants and
agrees, and each Holder of the Securities of each series, by its acceptance
thereof, likewise covenants and agrees, that the payment of the principal of and
premium, if any, and interest, if any, on each and all of the Securities is
hereby expressly subordinated and subject to the extent and in the manner set
forth in this Article, in right of payment to the prior payment in full of all

          Each Holder of the Securities of each series, by its acceptance
thereof, authorizes and directs the Trustee on its behalf to take such action as
may be necessary or appropriate to effectuate the subordination as provided in

          In the event (a) of any insolvency or bankruptcy proceedings or any
receivership, liquidation, reorganization or other similar proceedings in
respect of the Company or a substantial part of its property, or of any
proceedings for liquidation, dissolution or other winding up of the Company,
whether or not involving insolvency or bankruptcy, or (b) subject to the
provisions of Section 1503, that (i) a default shall have occurred with respect
to the payment of principal of or interest on or other monetary amounts due and
payable on any Senior Indebtedness, or (ii) there shall have occurred a default
(other than a default in the payment of principal or interest or other monetary
amounts due and payable) in respect of any Senior Indebtedness, as defined
therein or in the instrument under which the same is outstanding, permitting the
holder or holders thereof to accelerate the maturity thereof (with notice or
lapse of time, or both), and such default shall have continued beyond the period
of grace, if any, in respect thereof, and, in the cases of subclauses (i) and
(ii) of this clause (b), such default shall not have been cured or waived or
shall not have ceased to exist, or (c) that the principal of and accrued
interest on the Securities of any series shall have been declared due and
payable pursuant to Section 801 and such declaration shall not have been
rescinded and annulled as provided in Section 802, then:

               (1)  the holders of all Senior Indebtedness shall first be
          entitled to receive payment of the full amount due thereon, or
          provision shall be made for such payment in money or money's
          worth, before the Holders of any of the Securities are entitled
          to receive a payment on account of the principal of or interest
          on the indebtedness evidenced by the Securities, including,
          without limitation, any payments made pursuant to Articles Four
          and Five;

               (2)  any payment by, or distribution of assets of, the
          Company of any kind or character, whether in cash, property or
          securities, to which any Holder or the Trustee would be entitled
          except for the provisions of this Article, shall be paid or
          delivered by the person making such payment or distribution,
          whether a trustee in bankruptcy, a receiver or liquidating
          trustee or otherwise, directly to the holders of such Senior
          Indebtedness or their representative or representatives or to the
          trustee or trustees under any indenture under which any
          instruments evidencing any of such Senior Indebtedness may have
          been issued, ratably according to the aggregate amounts remaining
          unpaid on account of such Senior Indebtedness held or represented
          by each, to the extent necessary to make payment in full of all
          Senior Indebtedness remaining unpaid after giving effect to any
          concurrent payment or distribution (or provision therefor) to the
          holders of such Senior Indebtedness, before any payment or
          distribution is made to the Holders of the indebtedness evidenced
          by the Securities or to the Trustee under this Indenture; and

               (3)  in the event that, notwithstanding the foregoing, any
          payment by, or distribution of assets of, the Company of any kind
          or character,


                                      -71-
<PAGE>

          whether in cash, property or securities, in respect of principal of or
          interest on the Securities or in connection with any repurchase by the
          Company of the Securities, shall be received by the Trustee or any
          Holder before all Senior Indebtedness is paid in full, or provision is
          made for such payment in money or money's worth, such payment or
          distribution in respect of principal of or interest on the Securities
          or in connection with any repurchase by the Company of the Securities
          shall be paid over to the holders of such Senior Indebtedness or their
          representative or representatives or to the trustee or trustees under
          any indenture under which any instruments evidencing any such Senior
          Indebtedness may have been issued, ratably as aforesaid, for
          application to the payment of all Senior Indebtedness remaining unpaid
          until all such Senior Indebtedness shall have been paid in full, after
          giving effect to any concurrent payment or distribution (or provision
          therefor) to the holders of such Senior Indebtedness.

Notwithstanding the foregoing, at any time after the 123rd day following the
date of deposit of cash or Government Obligations pursuant to Section 701
(provided all conditions set out in such Section shall have been satisfied), the
funds so deposited and any interest thereon will not be subject to any rights of
holders of Senior Indebtedness including, without limitation, those arising
under this Article Fifteen; provided that no event described in clauses (d) and
(e) of Section 801 with respect to the Company has occurred during such 123-day
period.

          For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment which are subordinate
in right of payment to all Senior Indebtedness which may at the time be
outstanding to the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article.  The consolidation of the
Company with, or the merger of the Company into, another corporation or the
liquidation or dissolution of the Company following the conveyance or transfer
of its property as an entirety, or substantially as an entirety, to another
corporation upon the terms and conditions provided for in Article Eleven hereof
shall not be deemed a dissolution, winding-up, liquidation or reorganization for
the purposes of this Section 1502 if such other corporation shall, as a part of
such consolidation, merger, conveyance or transfer, comply with the conditions
stated in Article Eleven hereof.  Nothing in Section 1501 or in this Section
1502 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 907.

SECTION 1503.  Disputes with Holders of Certain Senior Indebtedness.

          Any failure by the Company to make any payment on or perform any other
obligation in respect of Senior Indebtedness, other than any indebtedness
incurred by the Company or assumed or guaranteed, directly or indirectly, by the
Company for money borrowed (or any


                                      -72-
<PAGE>

deferral, renewal, extension or refunding thereof) or any other obligation as to
which the provisions of this Section shall have been waived by the Company in
the instrument or instruments by which the Company incurred, assumed, guaranteed
or otherwise created such indebtedness or obligation, shall not be deemed a
default under clause (b) of Section 1502 if (i) the Company shall be disputing
its obligation to make such payment or perform such obligation and (ii) either
(A) no final judgment relating to such dispute shall have been issued against
the Company which is in full force and effect and is not subject to further
review, including a judgment that has become final by reason of the expiration
of the time within which a party may seek further appeal or review, or (B) in
the event that a judgment that is subject to further review or appeal has been
issued, the Company shall in good faith be prosecuting an appeal or other
proceeding for review and a stay or execution shall have been obtained pending
such appeal or review.

SECTION 1504.  Subrogation.

          Senior Indebtedness shall not be deemed to have been paid in full
unless the holders thereof shall have received cash (or securities or other
property satisfactory to such holders) in full payment of such Senior
Indebtedness then outstanding.  Subject to the prior payment in full of all
Senior Indebtedness, the rights of the Holders of the Securities shall be
subrogated to the rights of the holders of Senior Indebtedness to receive any
further payments or distributions of cash, property or securities of the Company
applicable to the holders of the Senior Indebtedness until all amounts owing on
the Securities shall be paid in full; and such payments or distributions of
cash, property or securities received by the Holders of the Securities, by
reason of such subrogation, which otherwise would be paid or distributed to the
holders of such Senior Indebtedness shall, as between the Company, its creditors
other than the holders of Senior Indebtedness, and the Holders, be deemed to be
a payment by the Company to or on account of Senior Indebtedness, it being
understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders, on the one hand, and
the holders of the Senior Indebtedness, on the other hand.

SECTION 1505.  Obligation of the Company Unconditional.

          Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness and the Holders, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders the principal of and interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the Holders and creditors of the Company
other than the holders of Senior Indebtedness, nor shall anything herein or
therein prevent the Trustee or any Holder from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article of the holders of Senior Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.


                                      -73-
<PAGE>

          Upon any payment or distribution of assets or securities of the
Company referred to in this Article, the Trustee and the Holders shall be
entitled to rely upon any order or decree of a court of competent jurisdiction
in which such dissolution, winding up, liquidation or reorganization proceedings
are pending for the purpose of ascertaining the persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon, and all other facts pertinent thereto or
to this Article.

SECTION 1506.  Priority of Senior Indebtedness Upon Maturity.

          Upon the maturity of the principal of any Senior Indebtedness by lapse
of time, acceleration or otherwise, all matured principal of Senior Indebtedness
and interest and premium, if any, thereon shall first be paid in full before any
payment of principal or premium, if any, or interest, if any, is made upon the
Securities or before any Securities can be acquired by the Company or any
sinking fund payment is made with respect to the Securities (except that
required sinking fund payments may be reduced by Securities acquired before such
maturity of such Senior Indebtedness).

SECTION 1507.  Trustee as Holder of Senior Indebtedness.

          The Trustee shall be entitled to all rights set forth in this Article
with respect to any Senior Indebtedness at any time held by it, to the same
extent as any other holder of Senior Indebtedness. Nothing in this Article shall
deprive the Trustee of any of its rights as such holder.

SECTION 1508.  Notice to Trustee to Effectuate Subordination.

          Notwithstanding the provisions of this Article or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts which would prohibit the making of any payment of moneys
to or by the Trustee unless and until the Trustee shall have received written
notice thereof from the Company, from a Holder or from a holder of any Senior
Indebtedness or from any representative or representatives of such holder and,
prior to the receipt of any such written notice, the Trustee shall be entitled,
subject to Section 901, in all respects to assume that no such facts exist;
provided, however, that, if prior to the fifth Business Day preceding the date
upon which by the terms hereof any such moneys may become payable for any
purpose, or in the event of the execution of an instrument pursuant to Section
702 acknowledging satisfaction and discharge of this Indenture, then if prior to
the second Business Day preceding the date of such execution, the Trustee shall
not have received with respect to such moneys the notice provided for in this
Section, then, anything herein contained to the contrary notwithstanding, the
Trustee may, in its discretion, receive such moneys and/or apply the same to the
purpose for which they were received, and shall not be affected by any notice to
the contrary, which may be received by it on or after such date; provided,
however, that no such



                                      -74-
<PAGE>

application shall affect the obligations under this Article of the persons
receiving such moneys from the Trustee.

SECTION 1509.  Modification, Extension, etc. of Senior Indebtedness.

          The holders of Senior Indebtedness may, without affecting in any
manner the subordination of the payment of the principal of and premium, if any,
and interest, if any, on the Securities, at any time or from time to time and in
their absolute discretion, agree with the Company to change the manner, place or
terms of payment, change or extend the time of payment of, or renew or alter,
any Senior Indebtedness, or amend or supplement any instrument pursuant to which
any Senior Indebtedness is issued, or exercise or refrain from exercising any
other of their rights under the Senior Indebtedness including, without
limitation, the waiver of default thereunder, all without notice to or assent
from the Holders or the Trustee.

SECTION 1510.  Trustee Has No Fiduciary Duty to Holders of Senior Indebtedness.

          With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and objectives as
are specifically set forth in this Indenture, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee.  The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if it shall mistakenly pay over or deliver to the
Holders or the Company or any other Person, money or assets to which any holders
of Senior Indebtedness shall be entitled by virtue of this Article or otherwise.

SECTION 1511.  Paying Agents Other Than the Trustee.

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context shall otherwise
require) be construed as extending to and including such Paying Agent within its
meaning as fully for all intents and purposes as if such Paying Agent were named
in this Article in addition to or in place of the Trustee; provided, however,
that Sections 1507, 1508 and 1510 shall not apply to the Company if it acts as
Paying Agent.

SECTION 1512.  Rights of Holders of Senior Indebtedness Not Impaired.

          No right of any present or future holder of Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Company or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

SECTION 1513.  Effect of Subordination Provisions; Termination.

          Notwithstanding anything contained herein to the contrary, other than
as provided in the immediately succeeding sentence, all the provisions of this
Indenture shall be subject to the provisions of this Article, so far as the same
may be applicable thereto.

          Notwithstanding anything contained herein to the contrary, the
provisions of this Article Fifteen shall be of no further effect, and the
Securities shall no longer be subordinated in right of payment to the prior
payment of Senior Indebtedness, if the Company shall have delivered to the
Trustee a notice to such effect. Any such notice delivered by the Company shall
not be deemed to be a supplemental indenture for purposes of Article Twelve.

                                         -3-


in no case be later than __________, _____.  The Series [  ] Securities shall
bear interest at the rate of ____% per annum, from _________, ____, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, as the case may be, payable quarterly (subject to deferral as set
forth herein), in arrears, on the first day of March, June, September and
December of each year, commencing _________, ____.  The amount of interest
payable for any such period will be computed on the basis of a 360-day year of
twelve 30-day months and for any period shorter than a full month, on the basis
of the actual number of days elapsed in such period.  In the event that any
Interest Payment Date is not a Business Day, then payment of interest payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day is in the next succeeding calendar year, such Interest
Payment Date shall be the immediately preceding Business Day, in each case with
the same force and effect as if made on such Interest Payment Date.  Any
interest installment in arrears or deferred during an extension of an Interest
Payment Period as set forth below will bear interest at the rate of __% per
annum, compounded quarterly (to the extent permitted by applicable law).  

         Each installment of interest on a Series [  ] Security shall be
payable to the Person in whose name such Series [  ] Security is registered at
the close of business on the Business Day 15 days preceding the corresponding
Interest Payment Date (the "Regular Record Date") for the Series [  ]
Securities; provided, however, that if the Series [  ] Securities are held
neither by the Series [  ] Trust nor by a securities depositary, the Company
shall have the right to change the Regular Record Date by one or more Officer's
Certificates.  Any installment of interest on the Series [  ] Securities not
punctually paid or duly provided for shall forthwith cease to be payable to the
Holders of such Series [  ] Securities on such Regular Record Date, and may be
paid to the Persons in whose name the Series [  ] Securities are registered at
the close of business on a Special Record Date to be fixed by the Trustee for
the payment of such Defaulted Interest.  Notice of such Defaulted Interest and
Special Record Date shall be given to the Holders of the Series 
[  ] Securities not less than 10 days prior to such Special Record Date, or may
be paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Series [  ] Securities may
be listed, and upon such notice as may be required by such exchange, all as more
fully provided in the Indenture.


<PAGE>

                                         -4-


         The Company shall have the right, at any time during the term of the
Series [ ] Securities, from time to time to extend the interest payment period
thereon for up to 20 consecutive quarters (the "Extension Period") during which
period interest will compound quarterly and the Company shall have the right to
make partial payments of interest on any Interest Payment Date; provided that no
Extension Period may extend beyond the Maturity Date of the Securities and
provided further that the Company shall not defer the interest payment period
with respect to Additional Interest Attributable to Taxes and shall make payment
thereof on the relevant Interest Payment Date.  At the end of the Extension
Period, the Company shall pay all interest then accrued and unpaid thereon
(together with additional interest thereon at the rate of __% per annum,
compounded quarterly, to the extent permitted by applicable law).  During any
such Extension Period the Company will not, and will not permit any subsidiary
of the Company to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Company's outstanding capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Company (including other Securities) that rank PARI PASSU with
or junior in interest to the Series [  ] Securities or make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any subsidiary of the Company if such guarantee ranks PARI PASSU or junior in
interest to the Series [  ] Securities (other than (a) dividends or
distributions in common stock of the Company, (b) payments under any Guarantee,
and (c) purchases of common stock related to the issuance of common stock under
any of the Company's benefit plans for its directors, officers or employees). 
Prior to the termination of any such Extension Period, the Company may further
extend the interest payment period, PROVIDED that no Extension Period shall
exceed 20 consecutive quarters or extend beyond the  Maturity Date of the Series
[ ] Securities.  Upon the termination of any Extension Period and upon the
payment of all amounts then due, the Company may select a new Extension Period,
subject to the foregoing requirements.  Except for Additional Interest
Attributable to Taxes, no interest shall be due and payable during an Extension
Period, except at the end thereof.  The Company shall give the Trustee and, if
any Series [  ] Preferred Securities are Outstanding, the Administrative
Trustees of the Series [ ] Trust notice of its election of an Extension Period
no less than 15 Business Days prior to the later of (i) the Regular Record Date
next preceding the first Interest Payment Date on which a distribution would
occur but for such election and (ii) five Business Days prior to such Interest
Payment Date.  Upon


<PAGE>

                                         -5-


receipt of any such notice, the Trustee shall give written notice of the
Company's election by mail to the Holders of the Series 
[  ] Securities not less than 10 Business Days prior to such Interest Payment
Date.  The Company also shall make a public announcement of such election in
accordance with New York Stock Exchange Rules not less than five Business Days
prior to such Regular Record Date.

         The principal of and interest on the Series [ ] Securities shall be
payable at, and registration and registration of transfers of the Series [  ]
Securities may be effected at, the office or agency of the Company in
______________________; provided, however, that, at the option of the Company,
payment of interest may be made (i) by check mailed to the address of the
Persons entitled thereto under the Indenture or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto under the Indenture; provided further,
that for so long as any Series [ ] Security is registered in the name of the 
Property Trustee of the Series [ ] Trust, payment of principal (including 
Redemption Price and interest) shall be made by wire transfer in immediately 
available funds at such place and to such account as may be designated by the 
Property Trustee of the Series [  ] Trust. The Trustee will initially be the 
agent of the Company for such service of notices and demands; provided, 
however, that the Company reserves the right to change, by one or more Officer's
Certificates, any such office or agent.  The Company will be the Security 
Registrar and the Paying Agent for the Series [  ] Securities.

         The Series [ ] Securities shall be subordinated in right of payment to
Senior Indebtedness as provided in Article Fifteen of the Indenture.  The Series
[ ] Securities shall be pari passu with the Parent Guarantee.

         The Series [ ] Securities shall be redeemable as provided in Section
102 below and in Article Four of the Indenture.

SECTION 102.  Redemption.

         At any time on or after _____________, the Company shall have the
right to redeem the Series [ ] Securities, in whole or, subject to the last
paragraph of this Section 102, in part, from time to time, at a Redemption Price
equal to 100% of the principal amount of Series [ ] Securities to be redeemed
plus accrued but unpaid interest, including any Additional Interest Attributable
to Taxes, if any, to the Redemption Date.



<PAGE>

                                         -6-


         If a Special Event shall occur and be continuing, the Company shall 
have the right to redeem the Series [ ] Securities within 90 days of the 
occurrence of such Special Event in whole but not in part, at a Redemption 
Price equal to 100% of the principal amount thereof plus accrued but unpaid 
interest, including Additional Interest Attributable to Taxes, if any, to the 
Redemption Date.

         The Series [  ] Securities will also be redeemable, in whole but not
in part, at the option of the Company upon the termination and liquidation of
the Series [  ] Trust pursuant to an order for the dissolution, termination or
liquidation of the Series [  ] Trust entered by a court of competent
jurisdiction at a Redemption Price equal to 100% of the principal amount of the
Series [  ] Securities then Outstanding plus any accrued and unpaid interest,
including Additional Interest Attributable to Taxes, if any, to the Redemption
Date.

         "Special Event" means a Tax Event or an Investment Company Event.

         "Tax Event" means the receipt by the Series [  ] Trust of an opinion
of counsel (which may be counsel to the Company or an affiliate but not an
employee thereof and which must be acceptable to the Property Trustee of the
Series [  ] Trust) experienced in such matters to the effect that, as a result
of (a) any amendment to, or change (including any announced prospective change)
in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein affecting taxation,
or (b) any amendment to, or change in an interpretation or application of, such
laws or regulations by any legislative body, court, governmental agency or
regulatory authority (including the enactment of any legislation and the
publication of any judicial decision or regulatory determination on or after the
date of issuance of the Series [  ] Preferred Securities), there is more than an
insubstantial risk that (i) the Series [  ] Trust is, or will be within 90 days
of the date of such opinion, subject to United States federal income tax with
respect to interest income received or accrued on the Series [  ] Securities,
(ii) interest payable by the Company on the Series [  ] Securities is not, or
within 90 days of the date of such opinion, will not be, deductible by the
Company, in whole or in part, for United States federal income tax purposes, or
(iii) the Series [  ] Trust is, or will be within 90 days of the date of such
opinion, subject to more than a de minimis amount of other taxes, duties or
other governmental charges.

         "Investment Company Event" means the occurrence of a change in law or
regulation or a change in interpretation or application of law or regulation by
any legislative body, court,


<PAGE>

                                         -7-


governmental agency or regulatory authority to the effect that the Series [  ]
Trust is or will be considered an "investment company" that is required to be
registered under the Investment Company Act of 1940, as amended, which change in
law becomes effective on or after the date of original issuance of the Series
[ ] Preferred Securities.

         The Company shall not redeem the Series [ ] Securities in part unless
all accrued and unpaid interest (including any Additional Interest Attributable
to Taxes) has been paid in full on all Series [ ] Securities Outstanding for all
quarterly interest periods terminating on or prior to the Redemption Date or if
a partial redemption of the Series [  ] Preferred Securities would result in a
delisting of such securities by any national securities exchange on which they
are then listed.

SECTION 103.  Global Security.

         In the event that, at any time subsequent to the initial
authentication and delivery of the Series [  ] Securities, the Series [  ]
Securities are to be held by a securities depositary, the Company may at such
time establish the matters contemplated in clause (r) in the second paragraph of
Section 301 of the Indenture in an Officer's Certificate supplemental to this
Supplemental Indenture.

SECTION 104.  Exchange.

         At any time, the Company may terminate the Series [  ] Trust and cause
the Series [  ] Securities to be distributed to holders of the Series [  ]
Preferred Securities and Series [  ] Common Securities in liquidation of the
Series [  ] Trust.

SECTION 105.  Registration of Transfer or Exchange.

         No service charge shall be made for the registration of transfer or
exchange of the Series [  ] Securities; provided, however, that the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with the exchange or transfer.

SECTION 106.  Form of Series [  ] Security.

         Series [  ] Securities shall have such other terms and provisions as
are provided in the form set forth in Exhibit A hereto, and shall be issued in

SECTION 107.  Listing.

         In the event that the Series [  ] Securities are distributed to
holders of the Preferred Securities as a result of the termination of Series 
[ ] Trust, the Company will use its best efforts to list the Series [  ]
Securities on the New York Stock Exchange or on such other exchange as the
Series [  ] Preferred Securities are then listed.

         MIDAMERICAN ENERGY COMPANY, a corporation duly organized and existing
under the laws of the State of Iowa (herein called the "Company," which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to _________________, or registered
assigns, the principal sum of __________ DOLLARS ($__________) on _________,
____, and to pay interest on said principal sum from ___________, ____, or from,
and excluding, the most recent Interest Payment Date through which interest has
been paid or duly provided for, quarterly in arrears on the first day of March,
June, September and December of each year, commencing __________, ____, at the
rate of ____% per annum until the principal hereof is paid or made available for
payment.  The amount payable on any Interest Payment Date shall be computed on
the basis of a 360-day year of twelve 30-day months.   Interest on the
Securities of this series will accrue from, and including, __________, ____
through the first Interest Payment Date, and thereafter will accrue, from, and
excluding, the last Interest Payment Date through which interest has been paid
or duly provided for.  In the event that any Interest Payment Date is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such Interest Payment Date.  The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be the Business Day 15 days preceding
such Interest Payment Date.  Any such interest not so punctually paid or duly
provided for shall


<PAGE>

                                         -11-


forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, of which notice shall be given to Holders of Securities not less than
10 days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities of this series may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in said Indenture.

         Payment of the principal of and premium, if any, and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in [The City of New York], 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; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Securities Register or (ii) by wire
transfer in immediately available funds at such place and to such account as may
be designated by the Person entitled thereto as specified in the Securities
Register.

         Reference is hereby made to the further provisions of this Security
summarized on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                        FORM OF REVERSE OF SERIES [ ] SECURITY

         This Security is one of a duly authorized issue of securities of the
Company, designated as its ____% Deferrable Interest Subordinated Debentures
(herein called the "Securities"), limited in aggregate principal amount to
$__________ issued under an Indenture, dated as of __________, ____,
supplemented by a ______ Supplemental Indenture, dated as of _________, ____,
(herein called the "Indenture"), from the Company to 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 such supplemental
indenture (the "Supplemental Indenture") reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Trustee, the Company and the Holders of the Securities, and of
the terms upon which the Securities are, and are to be, authenticated and
delivered.  This Security is one of the series designated on the face hereof.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         The Securities of this series are subject to redemption upon not less
than 30 nor more than 60 days' notice by mail, at any time on or after
__________, ____ as a whole or in part, at the election of the Company, at a
Redemption Price equal to 100% of the principal amount, together in the case of
any such redemption with accrued interest to, but not including, the Redemption
Date, but interest installments whose Stated Maturity is on or prior to such
Redemption Date will be payable to the Holder of such Security, or one or more
Predecessor Securities, of record at the close of business on the related
Regular Record Date referred to on the face hereof, all as provided in the
Indenture.

         The Securities of this series will also be redeemable at the option of
the Company if a Tax Event or an Investment Company Event (each as defined in
the Supplemental Indenture) shall occur and be continuing, in whole but not in
part, at a redemption price equal to 100% of the principal amount of the
Securities of this series then Outstanding plus any accrued and unpaid interest,
including Additional Interest Attributable to Taxes, if any, to the redemption
date, upon not less than 30 nor more than 60 days' notice given as provided in
the Indenture.


<PAGE>

                                         -14-


         The Securities of this series will also be redeemable, in whole but
not in part, at the option of the Company upon the termination and liquidation
of the Trust pursuant to an order for the dissolution, termination or
liquidation of the Trust entered by a court of competent jurisdiction at a
redemption price equal to 100% of the principal amount of the Securities of this
series then Outstanding plus any accrued and unpaid interest, including
Additional Interest Attributable to Taxes, if any, to the redemption date, upon
not less than 30 nor more than 60 days' notice given as provided in the
Indenture.

         In the event of the redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinated and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto.  Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes.  Each Holder hereof, by his acceptance hereof, hereby
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder upon
said provisions.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security upon compliance by the Company with certain
conditions set forth in the Indenture.

         If an Event of Default with respect to the Securities shall occur and
be continuing, the principal of the Securities may be declared due and payable
in the manner and with the effect provided in the Indenture.

         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 Holders of the Securities of each series to be
affected under the


<PAGE>

                                         -15-


Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Securities at the time
Outstanding of all series to be affected. The Indenture also contains provisions
permitting Holders of specified percentages in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security 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 Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or

         The Company has the right, at any time during the term of the
Securities of this series, from time to time to extend the interest payment
period thereon for up to 20 consecutive quarters (the "Extension Period") during
which period interest will compound quarterly and the Company shall have the
right to make partial payments of interest on any Interest Payment Date;
provided that no Extension Period may extend beyond the Maturity Date of the
Securities and provided further that the Company shall not defer the interest
payment period with respect to Additional Interest Attributable to Taxes and
shall make payment thereof on the relevant Interest Payment Date.  At the end of
the Extension Period, the Company shall pay all interest then accrued and unpaid
thereon (together with additional interest thereon at the rate of __% per annum,
compounded quarterly, to the extent permitted by applicable law).  During any
such Extension Period the Company will not, and will not permit any subsidiary
of the Company to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Company's outstanding capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Company (including other Securities) that rank PARI PASSU with

the Company of the debt securities of any subsidiary of the Company if such
guarantee ranks PARI PASSU or junior in interest to the Series [  ] Securities

payments under any Guarantee, and (c) purchases of common stock related to the
issuance of common stock under any of the Company's benefit plans for its
directors, officers or employees).  Prior to the termination of any such
Extension Period, the Company may further extend the interest payment period,
PROVIDED that no Extension Period shall exceed 20 consecutive quarters or extend
beyond the  Maturity Date of the Series [ ] Securities.  Upon the termination of
any Extension Period and upon the payment of all amounts then due, the Company
may select a new Extension Period, subject to the foregoing requirements. 
Except for Additional Interest Attributable to Taxes, no interest shall be due
and payable during an Extension Period, except at the end thereof.  Notice of
the Company's election of an Extension Period will be given as provided in or
pursuant to the Indenture. 

         The Securities are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof.  As provided in the
Indenture and subject to certain

like aggregate principal amount of Securities of this series and of like tenor
and of authorized denominations, as requested by the Holder surrendering the
same.

make transfers or exchanges of Securities of this series for a period of 15 days
immediately preceding the date of the mailing of any notice of redemption of
such Securities and the Company shall not be required to make transfers or
exchanges of any Securities of this series so selected for redemption in whole
or in part (except the unredeemed portion of thereof).

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

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

interest therein, the Holder of, and any Person that acquires a beneficial 
interest in, this Security agree that for United States federal, state and 
local tax purposes it is intended that this Security constitute indebtedness

in liquidation amount of Preferred Securities may, by vote, on behalf of all of
the Holders, waive any past Event of Default and its consequences.  Upon such
waiver, any such Event of Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this
Guarantee Agreement, but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.

         SECTION 2.07   Event of Default; Notice.

         (a)  The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders, notices of all Events of Default known to the Guarantee Trustee, unless
such defaults have been cured before the giving of such notice, provided that,
the Guarantee 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 Guarantee Trustee in good faith
determines that the withholding of such notice is in the interests of the
Holders.

         (b)  The Guarantee Trustee shall not be deemed to have knowledge of
any Event of Default unless the Guarantee Trustee shall have received written
notice, or a Responsible Officer charged with the administration of the Trust
Agreement shall have obtained written notice, of such Event of Default.

         SECTION 2.08  Conflicting Interests.  The Trust Agreement and the

         POWERS, DUTIES AND RIGHTS OF GUARANTEE TRUSTEE

         SECTION 3.01   Powers and Duties of the Guarantee Trustee.

         (a)  This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement or any rights hereunder to any Person except a Holder
exercising his or her rights pursuant to Section 5.04 or to a Successor
Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its
appointment to act as Successor Guarantee Trustee.  The right, title and
interest of the Guarantee Trustee shall automatically vest in any Successor
Guarantee Trustee, and such vesting and cessation of title shall be effective
whether or not conveyancing documents have been executed and delivered pursuant
to the appointment of such Successor Guarantee Trustee.

         (b)  The Guarantee Trustee, prior to the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants or obligations shall be read
into this Guarantee Agreement against the Guarantee Trustee.  In case an Event
of Default has occurred (that has not been cured or waived pursuant to Section
2.06), the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Guarantee Agreement, and use the same degree of care and skill in
its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

              (i)  prior to the occurrence of any Event of Default and
         after the curing or waiving of all such Events of Default that
         may have occurred:

                   (A)  the duties and obligations of the Guarantee
              Trustee shall be determined solely by the express provisions
              of this Guarantee Agreement, and the Guarantee Trustee shall
              not be liable except for the performance of such duties and
              obligations as are specifically set forth in this Guarantee
              Agreement; and

                   (B)  in the absence of bad faith on the part of the
              Guarantee Trustee, the Guarantee Trustee may conclusively
              rely, as to the truth of the statements and the correctness
              of the opinions expressed therein, upon any certificates or
              opinions furnished to the Guarantee Trustee and conforming
              to the


                                         -6-

<PAGE>


              requirements of this Guarantee Agreement; but in the case of any
              such certificates or opinions that by any provision hereof are
              specifically required to be furnished to the Guarantee Trustee,
              the Guarantee Trustee shall be under a duty to examine the same
              to determine whether or not they conform to the requirements of
              this Guarantee Agreement;

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

              (iii)     the Guarantee 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 a
         Majority in liquidation amount of the Preferred Securities
         relating to the time, method and place of conducting any
         proceeding for any remedy available to the Guarantee Trustee, or
         exercising any trust or power conferred upon the Guarantee
         Trustee under this Guarantee Agreement; and

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

         SECTION 3.02   Certain Rights of Guarantee Trustee.

         (a)  Subject to the provisions of Section 3.01:

              (i)  the Guarantee Trustee may rely and shall be fully

         Officers' Certificate;

              (iii) whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a
         matter be proved or established before taking, suffering or
         omitting any action hereunder, the Guarantee Trustee (unless
         other evidence is herein specifically prescribed) may, in the
         absence of bad faith on its part, request and rely upon an

         be promptly delivered by the Guarantor;

              (iv) the Guarantee Trustee may consult with counsel of its
         choice, and the written advice or opinion of such counsel with

         and protection in respect of any action taken, suffered or
         omitted by it hereunder in good faith and in accordance with such
         advice or opinion; such counsel may be counsel to the Guarantor
         or any of its Affiliates and may include any of its employees;
         the Guarantee Trustee shall have the right at any time to seek
         instructions concerning the administration of this Guarantee
         Agreement from any court of competent jurisdiction;

              (v)  the Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this
         Guarantee Agreement at the request or direction of any Holder,
         unless such Holder shall have provided to the Guarantee Trustee
         such adequate security and indemnity as would satisfy a
         reasonable person in the position of the Guarantee Trustee,
         against the costs, expenses (including attorneys' fees and
         expenses) and liabilities that might be incurred by it in
         complying with such request or direction, including such
         reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.02(a)(v) shall
         be taken to relieve the Guarantee Trustee, upon the occurrence of
         an Event of Default, of its obligation to exercise the rights and
         powers vested in it by this Guarantee Agreement;

              (vi) the Guarantee Trustee shall not be bound to make any

         on the part of any agent or attorney appointed with due care by
         it hereunder;

to perform any such act or acts or to exercise any such right, power, duty or
obligation.  No permissive power or authority available to the Guarantee Trustee

                        Trustee.

         (a)  Subject to Section 4.03(b), unless an Event of Default shall have
occurred and be continuing, the Guarantee Trustee may be appointed or removed
without cause at any time by the Guarantor.

                                      GUARANTEE

         SECTION 5.01   Guarantee.  The Guarantor irrevocably and
unconditionally agrees to pay in full to the Holders the Guarantee Payments
(without duplication of amounts theretofore paid by the Issuer), as and when
due, regardless of any defense, right of set-off or counterclaim which the
Issuer may have or assert.  The Guarantor's obligation to make a Guarantee
Payment may be satisfied by direct payment of the required amounts by the
Guarantor to the Holders or by causing the Issuer to pay such amounts to the
Holders.

         SECTION 5.02   Waiver of Notice and Demand.  The Guarantor hereby
waives notice of acceptance of this Guarantee Agreement and of any liability to
which it applies or may apply, presentment, demand for payment, any right to

proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.

         SECTION 5.03   Obligations Not Affected.  The obligation of the
Guarantor to make the Guarantee Payments under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

         (a)  the release or waiver, by operation of law or otherwise, of
    the performance or observance by the Issuer of any express or implied
    agreement, covenant, term or condition relating to the Preferred
    Securities to be performed or observed by the Issuer;

         (b)  the extension of time for the payment by the Issuer of all
    or any portion of the Distributions, Redemption Price, Liquidation
    Distribution or any other sums payable under the terms of the
    Preferred Securities or the extension of time for the performance of
    any other obligation under, arising out of, or in connection with, the
    Preferred Securities (other than an extension of time for payment of
    Distributions, Redemption Price, Liquidation Distribution or other sum
    payable that results from the extension of any interest payment period
    on the Debentures permitted by the Indenture);

         (c)  any failure, omission, delay or lack of diligence on the
    part of the Holders to enforce, assert or exercise any right,
    privilege, power or remedy conferred on the Holders pursuant to the
    terms of the Preferred Securities, or any action on the part of the
    Issuer granting indulgence or extension of any kind;

         (d)  the voluntary or involuntary liquidation, dissolution, sale
    of any collateral, receivership, insolvency, bankruptcy, assignment
    for the benefit of

    creditors, reorganization, arrangement, composition or readjustment of debt
    of, or other similar proceedings affecting, the Issuer or any of the assets
    of the Issuer;

         (e)  any invalidity of, or defect or deficiency in, the Preferred
    Securities;

         (f)  the settlement or compromise of any obligation guaranteed
    hereby or hereby incurred; or

         (g)  any other circumstance whatsoever that might otherwise
    constitute a legal or equitable discharge or defense of a guarantor,
    it being the intent of this Section 5.03 that the obligations of the
    Guarantor hereunder shall be absolute and unconditional under any and
    all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain consent
of, the Guarantor with respect to the happening of any of the foregoing.

         SECTION 5.04   Rights of Holders.  The Guarantor expressly
acknowledges that: (i) this Guarantee Agreement will be deposited with the
Guarantee Trustee to be held for the benefit of the Holders; (ii) the Guarantee
Trustee has the right to enforce this Guarantee Agreement on behalf of the
Holders; (iii) the Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee Agreement or exercising any trust or power conferred upon the
Guarantee Trustee under this Guarantee Agreement; and (iv) any Holder may
institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement without first instituting a legal
proceeding against the Issuer or any other person or entity.

         SECTION 5.05   Guarantee of Payment.  This Guarantee Agreement creates
a guarantee of payment and not of collection.   This Guarantee Agreement will
not be discharged except by payment of the Guarantee Payments in full (without
duplication).

         SECTION 5.06   Subrogation.  The Guarantor shall be subrogated to all
(if any) rights of the Holders against the Issuer in respect of any amounts paid
to the Holders by the Guarantor under this Guarantee Agreement; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any rights which
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee Agreement,
if, at the time of any such payment, any amounts of Guarantee Payments are due
and unpaid under this Guarantee Agreement.  If any amount shall
be paid to the Guarantor in violation of the preceding sentence, the Guarantor
agrees to hold such amount in trust for the Holders and to pay over such amount
to the Holders.

         SECTION 5.07   Independent Obligations.  The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Issuer
with respect to the Preferred Securities and that the Guarantor shall be liable
as principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03.


                                      ARTICLE VI

                                    SUBORDINATION

         SECTION 6.01   Subordination.  This Guarantee Agreement will
constitute an unsecured obligation of the Guarantor and will rank (i)
subordinate and junior in right of payment to all other liabilities of the
Guarantor, including the Debentures, except those made PARI PASSU or subordinate
by their terms, (ii) PARI PASSU with the most senior preferred or preference
stock now or hereafter issued by the Guarantor and with any guarantee now or
hereafter entered into by the Guarantor in respect of any preferred or
preference stock of any Affiliate of the Guarantor, and (iii) senior to all
common stock of the Guarantor.  Nothing in this Section 6.01 shall apply to
claims of, or payments to, the Guarantee Trustee under or pursuant to Section
4.02 hereof.


                                     ARTICLE VII

         SECTION 7.01   Termination.  This Guarantee Agreement shall terminate
and be of no further force and effect upon: (i) full payment of the Redemption
Price of all Preferred Securities, and all accrued and unpaid Distributions to
the date of redemption, (ii) the distribution of Debentures to Holders in
exchange for all of the Preferred Securities or (iii) full payment of the
amounts payable in accordance with the Trust Agreement upon liquidation of the
Issuer.  Notwithstanding the foregoing, this Guarantee Agreement will continue
to be effective or will be reinstated, as the case may be, if at any time any
Holder must restore payment of any sums paid with respect to the Preferred
Securities or under this Guarantee Agreement.

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-

<PAGE>

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.

         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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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,

option, revoke the interest rate, in the case of a Fixed Rate Note, or the

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

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

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

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.

         (7)  the commencement by the Company of a voluntary 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
    the consent by it to the entry of an order for relief in an involuntary
    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-

<PAGE>

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-

<PAGE>

    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-

<PAGE>

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.

         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.

         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-

<PAGE>

         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-

<PAGE>

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.

                                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-

<PAGE>

    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-

<PAGE>

         (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-

<PAGE>

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

    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-

<PAGE>

         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-

<PAGE>

    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-

<PAGE>

    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-

<PAGE>

    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-

<PAGE>

    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-

<PAGE>

    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-

<PAGE>

    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.

         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-

<PAGE>

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-

<PAGE>

    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-

<PAGE>

distribution with respect to the secured portion, if any, of such claim.  The

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:

    given rise to the obligation to account, if such Trustee had continued as
    Trustee, occurred after the beginning of such four months' period; and

    four months after such resignation or removal.

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

         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-

<PAGE>

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
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 9.07.

         If an appointment is made pursuant to this Section 9.07, the Notes may
have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternate certificate of authentication in the following
form:

                              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.

         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.

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

affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         (c)  Any supplemental indenture authorized by this Section 13.01 may
be executed by the Company and the Trustee without the consent of the Holders of
any of the Notes then outstanding, notwithstanding any of the provisions of

then outstanding that would be affected by the particular supplemental

supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any

Noteholders; PROVIDED, HOWEVER, that no such supplemental indenture shall:

         (1)  change the Stated Maturity of any Note; or reduce the rate
    of interest on any Note; or change the method of calculating interest,
    or any term used in the calculation of interest, or the period for

    or any premium or interest thereon is payable; or change the date on which
    any Note may be redeemed; or adversely affect the rights of any Noteholder
    to institute suit for the enforcement of any payment of principal of or any
    premium or interest on any Note; in each case without the consent of the
    Holder of each Note then outstanding that would be affected thereby (for
    purposes of this Section 13.02 (a)(1) only, the term "Note" shall include
    Notes for which an offer to purchase has been accepted by the Company); or

         (2)  reduce the aforesaid percentage of Notes, the Holders of
    which are required to consent to any such supplemental indenture, or

    past defaults or Events of Default hereunder or the consequences thereof,
    in each case without the consent of the Holders of all of the Notes then
    outstanding.

         (b)  Upon the request of the Company, accompanied by a copy of the
Board Resolution authorizing the execution of any such supplemental indenture,
and upon the filing with the Trustee of evidence of the consent of Noteholders
as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

         (c)  It shall not be necessary for the consent of the Holders of Notes
under this Section 13.02 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such consent shall approve
the substance thereof.

         (d)  Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to this Section 13.02, the Company shall
give notice in the manner provided in Section 15.10, setting forth in general
terms the

of the Trustee and the Board of Directors to any modification of this Indenture
contained in any such supplemental indenture may be prepared and executed by the
Company, authenticated by the Trustee and delivered in exchange for the Notes
then outstanding.

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

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,

prepaid, addressed to the Holders of such Notes at their last addresses as the

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

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

                                   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

<PAGE>

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

<PAGE>


         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.

         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


<PAGE>

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 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.

         If at any time the Depositary for this Global Note notifies the
Company that it is unwilling or unable to continue as Depositary for this Global
Note or if at any time the Depositary for this Global Note shall no longer be
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 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

<PAGE>

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
the Company's election to issue this Note in global form shall no longer be
effective with respect to this Global Note and the Company will execute, and the
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.

         If  agreed by the Company and the Depositary with respect to Notes
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

contrary.

                              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

<PAGE>

         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

<PAGE>

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
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


                                         B-6

<PAGE>

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
of the Indenture upon compliance by the Company with certain conditions
specified therein, which provisions apply to this Note.

         Unless otherwise specified in an annex attached hereto, the Notes are
issuable only in registered form, without coupons, in denominations of $1,000
and integral multiples thereof.  As provided in the Indenture and subject to
certain limitations specified therein, this Note 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, as requested by the Holder surrendering this Note.

         As provided in the Indenture and subject to the limitations specified
therein, upon due presentment of this Note for registration of transfer at an
office or agency of the Trustee in the Borough of Manhattan, The City of New
York, maintained for such purpose, duly endorsed by, or accompanied by

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

of transfer, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

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

         The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the State of New York.

         All terms used in the Note which are defined in the Indenture but are

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

name this Note is registered at the close of business on the Record Date
specified above next preceding such Interest Payment Date; PROVIDED, HOWEVER,

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

Authenticating Agent, by manual signature of an authorized signatory, this

                              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

<PAGE>

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

<PAGE>

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

<PAGE>

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


                                         C-7

<PAGE>

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.

         If at any time the Depositary for this Global Note notifies the
Company that it is unwilling or unable to continue as Depositary for this Global
Note or if at any time the Depositary for this Global Note shall no longer be
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 this Global Note.  If (A) a successor
Depositary for this 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 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 the Company's election to issue this Note in global form shall no
longer be effective with respect to this Global Note and the Company will
execute, and the 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.

         If  agreed by the Company and the Depositary with respect to Notes
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

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

                                         C-8

<PAGE>

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.

         The Indenture contains provisions for the satisfaction and discharge
of the Indenture upon compliance by the Company with certain conditions
specified therein, which provisions apply to this Note.

         Prior to due presentment of this Global Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
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.

         The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the State of New York.

         All terms used in the Note which are defined in the Indenture but are
not defined in this Note shall have the meanings assigned to them in the
Indenture.

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

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

name this Note is registered at the close of business on the Record Date
specified above next preceding such Interest Payment Date; PROVIDED, HOWEVER

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

Note is presented to the Trustee in time for the Trustee to make such payment in

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

PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

                              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

<PAGE>

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

<PAGE>

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.

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

MidAmerican Energy Company
666 Grand Avenue
Des Moines, Iowa 50322

Ladies and Gentlemen:

I refer to the proposed issuance and sale by you ("Company") of a presently 
indeterminate number of medium-term notes ("Notes") pursuant to the terms of 
an indenture from the Company to The First National Bank of Chicago, as 
trustee ("Note Indenture"), and the registration of a presently indeterminate 
number of preferred securities ("Preferred Securities") of MidAmerican Energy 
Financing I and II ("Trusts") (and related Guarantees and Junior Subordinated 
Debentures ("Debentures") pursuant to the terms of indentures from the 
Company to The First National Bank of Chicago, as trustee ("Debenture 
Indenture" and "Guarantee Indenture")), such Preferred Securities to be 
offered in underwritten public offerings, as contemplated in the Registration 
Statement on Form S-3 to be filed by the Company on or about the date hereof 
("Registration Statement") with the Securities and Exchange Commission 
("Commission") under the Securities Act of 1933, as amended ("Act").

I have examined such documents and satisfied myself as to such matters of
procedure, law and fact as I deem relevant for the purposes of this opinion, and
based upon the foregoing, I advise you that, in my opinion, (a) the Company is a
duly incorporated and validly existing corporation under the laws of the State
of Iowa, and (b) when the following additional steps have been taken:

    1.  The issuance, execution, delivery and sale of the Notes, Debentures and
Guarantees, and the execution and delivery of the Note Indenture, the Debenture
Indenture and the Guarantee Indenture shall have been authorized by your Board
of Directors;

    2.  The Note Indenture, Debenture Indenture, Guarantee Indenture, and any
applicable Supplemental Indentures thereto shall have been qualified under the
Trust Indenture Act of 1939, as amended ("39 Act");

    3.  Your proposed Registration Statement being filed with the Commission
under the Act, and any required amendments and post-effective amendments thereto
shall have become effective under the Act;

                                                                          Page 2



    4.  The Federal Energy Regulatory Commission ("FERC") and the Illinois
Commerce Commission ("ICC") each shall have issued their appropriate orders upon
an application with respect to the Notes, Debentures and Guarantees filed with
FERC and ICC, respectively;

    5.  The Notes, Debentures and Guarantees shall have been issued and sold in
accordance with the authorizations of the Board of Directors of the Company, and
the appropriate orders of the FERC and ICC in response to the above mentioned
applications, and;

    6.  All statutory fees imposed upon or by reason of the issuance of the
Notes, Debentures and Guarantees shall have been paid,

    (i) the Notes, Debentures and Guarantees will be legally issued and will
    constitute legal, valid and binding obligations of the Company enforceable
    in accordance with their terms, except as enforcement thereof may be
    limited by bankruptcy, insolvency or other laws affecting enforcement of
    creditors' rights, or by general principles of equity, and

    (ii) the Notes, Debentures and Guarantees will be entitled to the benefits
    provided by their respective indentures, as supplemented and as to be
    supplemented by supplemental indentures creating each series of such Notes
    and Debentures.

I am further of the opinion that no approval of any state or federal regulatory
authority, other than the FERC, ICC and the Commission under the Act and the 39
Act is required with respect to the proposed offering, issuance and sale of the
Notes, Debentures and Guarantees.

I do not find it necessary for the purposes of this opinion, and accordingly I
do not purport herein, to cover the application of state securities or "blue
sky" laws relating to sales of Notes, Debentures and Guarantees.

I consent that copies of this opinion may be filed with the Commission as an 
exhibit to the  Registration Statement on Form S-3 with respect to the Notes, 
Debentures and Guarantees, and to the references to my name under the 
captions "Legal Matters" in such Registration Statement.

Sincerely,




/s/John A. Rasmussen, Jr.

          Re:  MIDAMERICAN ENERGY FINANCING I

Ladies and Gentlemen:

          We have acted as special Delaware counsel for MidAmerican Energy
Financing I, a Delaware business trust (the "Trust"), in connection with the
matters set forth herein. At your request, this opinion is being furnished to
you.

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a)  The Certificate of Trust of the Trust, dated October 24, 1996
(the "Certificate"), as filed in the office of the Secretary of State of the
State of Delaware (the "Secretary of State") on October 31, 1996;

          (b)  The Trust Agreement of the Trust, dated as of October 31, 1996,
among MidAmerican Energy Company, an Iowa corporation ("MidAmerican"), and the
trustees of the Trust named therein;

          (c)  The Registration Statement (the"Registration Statement") on Form
S-3, including a preliminary prospectus and a prospectus supplement (the
"Prospectus"), relating to the __% Preferred Securities of the Trust, Series A,
representing preferred

undivided beneficial interests in the Trust (each, a "Preferred Security" and
collectively, the "Preferred Securities"), as filed by MidAmerican, the Trust
and others as set forth therein with the Securities and Exchange Commission on
November 1, 1996;

          (d)  A form of Amended and Restated Trust Agreement of the Trust, to
be entered into among MidAmerican, the trustees of the Trust named therein, and
the holders, from time to time, of undivided beneficial interests in the Trust
(the "Trust Agreement"), attached as an exhibit to the Registration Statement;
and

          (e)  A Certificate of Good Standing for the Trust, dated the date
hereof, obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed above, and we have assumed that there exists no
provision in any document that we have not reviewed that bears upon or is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

          For purposes of this opinion, we have assumed (i) that the Trust
Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Preferred Security is to be issued by the Trust (collectively, the "Preferred
Security Holders") of a Preferred Security Certificate for such Preferred

Security and the payment for the Preferred Security acquired by it, in
accordance with the Trust Agreement and the Registration Statement, and (vii)
that the Preferred Securities are issued and sold to the Preferred Security
Holders in accordance with the Trust Agreement and the Registration Statement.
We have not participated in the preparation of the Registration Statement and
assume no responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

          Based upon the foregoing, and upon our examination of such question s
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualification, limitations and
exceptions set forth herein, we are of the opinion that:

          1.   The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 DEL. C.
Section 3801, ET SEQ.

          2.   The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.   The Preferred Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement. In addition, we
hereby consent to the use of our name under the heading "Legal Matters" in the
Prospectus. In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder. Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.

                                        Very truly yours,
